Description

Carrier measurement method and terminal equipment

Technical Field

The present application relates to the field of communications, and in particular, to a method for carrier measurement and a terminal device.

Background

A terminal device supporting New Radio (NR) system communication needs to perform cell identification and measurement on a carrier other than a serving carrier. The serving carrier is a carrier where a serving cell accessed by the terminal device is located. A carrier is a carrier adjacent to a serving carrier. For example, the terminal apparatus searches and detects a Synchronization Signal Block (SSB) of a cell on a carrier to acquire a physical cell identification, timing information, and measurement results based on the SSB of the cell, and the like.

For each carrier, the network device configures corresponding reference signal configuration information for notifying the terminal device of information such as the period of the reference signal on the carrier. The network device configures a uniform measurement interval pattern for all carriers that the terminal device needs to detect. The terminal device may perform cell identification or measurement operation on all carriers according to the information included in the measurement interval pattern, for example, in the measurement interval included in the measurement interval pattern. Currently, for a terminal device, all carriers to be detected need to be measured according to measurement indexes specified by a protocol. However, in the fifth Generation mobile communication technology (5-Generation,5G), there is no definition related to the measurement index, so that an error may occur in the terminal device during the measurement of multiple carriers, which affects normal communication.

The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment.

The Network device in this embodiment may be a device for communicating with a terminal device, where the Network device may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) System or a Code Division Multiple Access (CDMA) System, may also be a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, may also be an evolved node b (eNB, or eNodeB) in an LTE System, may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or may be a relay Station, an Access point, a vehicle-mounted device, a wearable device, a Network device in a future 5G Network, or a Network device in a future evolved PLMN Network, and the like, and the embodiment of the present invention is not limited.

Fig. 1 is a schematic diagram of a communication system suitable for use with the method of carrier measurement of the present application. As shown in fig. 1, the communication system 100 includes a network device 102, and the network device 102 may include a plurality of antennas, e.g.,

antennas

104, 106, 108, 110, 112, and 114. Additionally, network device 102 can additionally include a transmitter chain and a receiver chain, each of which can comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, encoders, demultiplexers, or antennas, etc.), as will be appreciated by one skilled in the art.

Network device 102 may communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it is understood that network device 102 may communicate with any number of terminal devices similar to

terminal devices

116 or 122.

End devices

116 and 122 can be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable device for communicating over wireless communication system 100.

As shown in fig. 1, terminal device 116 is in communication with antennas 112 and 114, where antennas 112 and 114 transmit information to terminal device 116 over forward link 118 and receive information from terminal device 116 over reverse link 120. In addition, terminal device 122 is in communication with

antennas

104 and 106, where

antennas

104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.

In a FDD system, for example, forward link 118 may utilize a different frequency band than that used by reverse link 120, and forward link 124 may utilize a different frequency band than that used by reverse link 126.

As another example, in TDD systems and full duplex (full duplex) systems, forward link 118 and reverse link 120 can utilize a common frequency band and forward link 124 and reverse link 126 can utilize a common frequency band.

Each antenna (or group of antennas consisting of multiple antennas) and/or area designed for communication is referred to as a sector of network device 102. For example, antenna groups may be designed to communicate to terminal devices in a sector of the areas covered by network device 102. During communication by network device 102 with

terminal devices

116 and 122 over forward links 118 and 124, respectively, the transmitting antennas of network device 102 may utilize beamforming to improve signal-to-noise ratio of forward links 118 and 124. Moreover, mobile devices in neighboring cells can experience less interference when network device 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage area, as compared to a manner in which a network device transmits through a single antenna to all its terminal devices.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to produce multiple code blocks.

Furthermore, the communication system 100 may be a PLMN network or a device-to-device (D2D) network or a machine-to-machine (M2M) network or other networks, and fig. 1 is a simplified schematic diagram for example, and other network devices may be included in the network, which is not shown in fig. 1.

Terminal equipment supporting NR system communication needs to perform cell identification and measurement on multiple carriers. It should be understood that these carriers may be either co-frequency carriers or inter-frequency carriers. The serving carrier refers to a carrier in which a serving cell of the terminal device is located, and may also be referred to as a co-frequency carrier. The terminal device may perform data transmission and reception with the serving cell on the serving carrier. The inter-frequency carrier is a carrier other than the serving carrier. The different-frequency carrier and the same-frequency carrier may belong to the same system, for example, an NR system, an LTE system, a GSM system, and the like. Of course, the co-frequency carrier and the inter-frequency carrier may belong to different systems. The terminal device does not perform data transmission and reception on the pilot frequency carrier, but performs cell search, measurement of a synchronization signal block SSB and a reference signal of a detection cell, and the like to acquire a physical cell identifier, timing information, a measurement result based on the reference signal, and the like of the pilot frequency cell. The intra-frequency carrier may be an intra-frequency carrier defined by an existing protocol. The inter-frequency carrier may be an inter-frequency (inter-frequency) carrier defined by an existing protocol.

A Synchronization signal block, or referred to as a Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) block, is a signal structure suitable for use in 5G and beyond communication systems. Fig. 2 is a schematic diagram of one possible structure of a Synchronization Signal block, which includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH), as shown in fig. 2. The PSS and SSS mainly serve to help the ue identify and synchronize with the cell, and the PBCH contains the most basic system information such as the system frame number, intra-frame timing information, etc. The successful reception of the synchronization signal block by the user equipment is a prerequisite for its access to the cell.

For each carrier, especially for inter-frequency carriers, the network device configures corresponding reference signal configuration information for notifying the terminal device of information such as a period for measuring or receiving the reference signal on the carrier. Taking the sync signal block as an example for explanation, the network device configures SSB Measurement Timing Configuration (SMTC) to the terminal device. The SMTC includes an SMTC period, where the SMTC period is a period for the terminal device to receive or measure the SSB, and the SMTC may further include a position and a length of a SSB reception window. That is, for different carriers, such as an inter-frequency carrier or an inter-frequency carrier, the network device configures an SMTC pattern (corresponding to SMTC) accordingly. Fig. 3 is a schematic diagram of 5 SMTC patterns configured for 5 carriers. The SSB is used as an example for explanation. The SMTC pattern may include information of the SMTC period, the position of the SSB reception window, etc., and as shown in fig. 3, the SMTC period is 20ms for carrier 1, i.e., the time interval between the reception windows of two SSBs is 20 ms. For carriers 2 to 5, the SMTC periods are 40ms, 80ms, 160ms, respectively.

It should be understood that fig. 3 is merely exemplary, and is intended to illustrate the form and inclusion of SMTC. The SMTC may also be in other representations, for example, in the form of a table. Alternatively, the SMTC may also include other content. The embodiments of the present application are not limited thereto.

For a certain terminal device, the network device configures a uniform Measurement Gap Pattern (MGP) for all or part of carriers (including co-frequency carriers and/or inter-frequency carriers) that the terminal device needs to detect, or all or part of carriers (including co-frequency carriers and/or inter-frequency carriers) within a certain frequency range. The MGP may include information of a Measurement Gap Length (MGL), a Measurement Gap Repetition Period (MGPR), and the like. The terminal device may perform cell identification or Measurement operation on multiple carriers according to information included in the Measurement interval pattern, for example, in a time period with a duration of a Measurement interval (Measurement Gap) time length. Fig. 4 is a schematic diagram of a measurement interval pattern for a 5 carrier configuration. The description will be made by taking the synchronization signal block as an example. As shown in fig. 4, the measurement interval repetition period is 40ms, and the SMTC periods are 20ms, 40ms, 80ms, 160ms, and 160ms for carriers 1 to 5, respectively. The measurement interval pattern is applied to carriers 1 to 5. The terminal device may perform operations such as measurement of the SSB on the carriers 1 to 5 in a time period in which the measurement interval is located (the time length is the measurement interval length). For example, during the measurement interval labeled 1, the reference signals on carriers 1,2, and 3 may be measured simultaneously. The reference signals on carriers 1,2 and 4 can be measured simultaneously during the measurement interval labeled 2.

In the standard protocol, some measurement indicators (measurement requirements) need to be defined to specify the measurement behavior of the terminal device, especially in inter-frequency measurement. For example, the measurement indicator may include a cell identification time. Synchronization signal detection time, reference signal index reading time, etc. The terminal device performs measurement and the like of signals on a plurality of carriers based on these measurement indexes.

Currently, in the LTE system, for a terminal device, all carriers that it needs to measure define the same measurement index. However, since the periods of the reference signals configured on the respective carriers in NR are different. The chances that each carrier can be measured in the same time period are different. For example, the description will be made by taking the example shown in fig. 3. The SMTC periods for carriers 1 to 5 are configured differently. The SMTC period for carrier 1 is 20ms, the SMTC period for carrier 5 is 160ms, and the MGPR value is 40 ms. In the same time period, the starting positions of the receive windows of carrier 1 and carrier 5 are assumed to be the same. For example, carrier 1 may get 4 measurement opportunities and carrier 5 may only get 1 measurement opportunity in a 160ms period. To ensure that there are enough measurement opportunities on those carriers with large SMTC periods, it is necessary to define a long measurement index. For example. Long cell identification time or measurement period, etc. However, the long measurement index is not favorable for the fast moving performance of the terminal device. The performance of the terminal equipment is poor, and the user experience is influenced.

In 5G, the measurement index of the co-channel carrier assumes that the terminal device has at least one measurement opportunity in each SMTC period (or each MGPR) on average. It is assumed that the measurement index of the pilot carrier is similar to the above definition. That is, the inter-frequency measurement indicator is that the terminal device has at least one chance to perform measurement in each SMTC period (or each MGPR) on average for each carrier. Since the inter-frequency carrier needs to be measured on multiple carriers, as shown in fig. 4, for a terminal device, there may be multiple carriers that need to be measured at the same time within a certain same Measurement Gap (Measurement Gap). For example, over measurement interval 1, reference signals on carriers 1,2,3 need to be measured simultaneously. That is, the measurement interval available for one carrier may collide with the measurement interval available for the other carrier. If the terminal device does not support simultaneous measurements on two or more carriers, then there is no guarantee that measurements will be available within each SMTC period (or each MGRP) for one or both of carriers 1,2, 3. That is, such measurement indexes require the terminal device to meet certain capability requirements, which may increase the cost of the terminal device.

The existing protocol has no definition of pilot frequency carrier measurement requirements, and pilot frequency measurement behaviors of terminal equipment cannot be restricted. The performance of the terminal equipment during the pilot frequency carrier measurement is affected, which causes the pilot frequency measurement delay of the terminal equipment to be too long, and affects the normal communication of the terminal equipment.

Based on the foregoing problems, embodiments of the present application provide a method for carrier measurement, and for a terminal device, a measurement indicator on a carrier may be defined according to measurement configuration information related to each carrier that the terminal device needs to measure. The fairness and the competitiveness of the measurement opportunities of different carriers are considered. On the basis of fully considering the equal measuring opportunity on each carrier, the measuring time delay of the terminal equipment can be reduced. Meanwhile, the method avoids the over-high requirement on the measuring capability of the terminal equipment and reduces the cost of the terminal equipment. The terminal equipment can normally carry out communication. The user experience is improved. It should be understood that the carrier measurement method can also be applied to co-channel carriers.

The method for carrier measurement provided in the present application is described in detail below with reference to fig. 5, where fig. 5 is a schematic flowchart of a method 200 for carrier measurement according to an embodiment of the present application, and the method 200 may be applied to the scenario shown in fig. 1, and of course, may also be applied to other communication scenarios, and the embodiment of the present application is not limited herein.

As shown in fig. 5, the method 200 includes:

s210, the terminal device determines a first measurement requirement on a first carrier according to first measurement configuration information, second measurement configuration information and a first parameter of the first carrier, where the second measurement configuration information includes measurement configuration information applied to at least two carriers, and the at least two carriers include the first carrier.

The first parameter is determined according to the first measurement configuration information and the second measurement configuration information of the first carrier, or the first parameter is determined according to the number of effective detected carriers of the terminal device.

S220, the terminal device performs measurement on the first carrier according to the first measurement requirement.

In the carrier measurement method provided by the present application, for each carrier to be measured that needs to be measured by the terminal device, the measurement requirement (measurement index) of the carrier to be measured is determined according to the measurement configuration information (first measurement configuration information) on the carrier to be measured (first carrier), the carrier measurement configuration information (second measurement configuration information) applicable to the plurality of carriers that need to be detected by the terminal device (including the carrier to be measured), and one parameter (first parameter). The first parameter is determined according to the measurement configuration information of the carrier to be measured and the second measurement configuration information, and corresponds to the carrier to be measured. Or the first parameter is determined according to the number of effective detection carriers of the terminal equipment. That is, in the determination process of the measurement requirement of the carrier to be measured, the configuration information of the carrier to be measured and other measurement configuration information related to the carrier to be measured are fully considered. And determining the measurement requirement corresponding to each carrier according to the actual situation of each carrier. And realizing differential processing on different carriers. The fairness and the competitiveness of the measurement opportunities of different carriers are considered. On the basis of fully considering the measurement opportunity of each carrier, the measurement delay of the terminal equipment can be reduced. Meanwhile, the method avoids the over-high requirement on the measuring capability of the terminal equipment and reduces the cost of the terminal equipment. The terminal equipment can normally carry out communication. The user experience is improved.

Specifically, in S210, when the terminal device needs to measure one of the carriers (taking the first carrier as an example for description), it is necessary to determine a first measurement requirement of the first carrier, which may be referred to as a first measurement index or the like, for standardizing the measurement behavior of the terminal device on the first carrier.

The first measurement requirement is determined according to first measurement configuration information, second measurement configuration information and a first parameter of the first carrier. The first measurement configuration information is measurement configuration information corresponding to the first carrier, and the corresponding first measurement configuration information may be the same or different for different carriers. For example, as shown in fig. 3 or fig. 4, 5 carriers respectively have first measurement configuration information corresponding to the carriers, and the 5 first measurement configuration information are different. It should be understood that the measurement configuration information corresponding to 5 carriers, respectively, may be referred to as first measurement configuration information, but the content included in the 5 first measurement configuration information is actually different, or the measurement configuration information corresponding to 5 carriers, respectively, may be referred to as different measurement configuration information. The embodiments of the present application are not limited thereto. For example, the first measurement configuration information may be an SMTC pattern or the like. The SMTC pattern for each carrier may be different.

The second measurement configuration information includes configuration information applied to a plurality of carriers (at least two carriers) including the first carrier. For example, as shown in fig. 4, the second measurement configuration information may be a measurement interval pattern applied to carriers 1 to 5, and the first carrier may be any one of carriers 1 to 5. It should be understood that the multiple carriers may be all carriers that the terminal device needs to detect, or all carriers within a certain frequency range. The embodiments of the present application are not limited thereto. The first parameter corresponds to the first carrier and is determined according to the first measurement configuration information and the second measurement configuration information of the first carrier, or the first parameter is determined according to the number of effective detection carriers of the terminal device. The number of valid detection carriers is related to the capabilities of the terminal device. The number of valid detection carriers corresponding to different terminal devices may be the same or different. The number of active monitor carriers for each carrier may be the same or different. That is, various measurement configuration information related to the first carrier is fully considered in the process of determining the first measurement requirement of the first carrier. It is ensured that the differentiated processing is carried out for different carriers.

When the first parameter is determined according to the number of effective detected carriers of the terminal device, the number of effective detected carriers corresponding to different terminal devices may be different because the number of effective detected carriers is related to the capability of the terminal device. Also, for a terminal device, the requirements for different carriers are different, or in other words, the importance of different carriers to the terminal device is different. Therefore, the number of active monitoring carriers corresponding to each carrier may be the same or different. For all carriers that need to be measured, the same first parameter (carrier coefficient) is corresponded. Or, it may be a first parameter corresponding to each carrier to be measured. The embodiments of the present application are not limited thereto.

In S220, the terminal device performs measurement on the first carrier according to the first measurement requirement. For example, the terminal device performs measurement of the reference signal on the first carrier according to the determined first measurement requirement, and the like. The terminal equipment measures signals according to the measurement requirement corresponding to the carrier waves to be measured, and differential processing of different carrier waves can be guaranteed. Different carriers can use different measurement requirements, and fairness and competitiveness of measurement opportunities of the different carriers are fully considered.

It should be understood that, in the embodiment of the present application, the first carrier may be an inter-frequency carrier, and may also be an intra-frequency carrier. At least two carriers applied by the second measurement configuration information may be both common-frequency carriers and pilot-frequency carriers, or may include common-frequency carriers, pilot-frequency carriers, and the like, or may include other standard carriers and the like. The embodiments of the present application are not limited thereto.

Optionally, as an embodiment, the first parameter is determined according to the first measurement configuration information and the second measurement configuration information of each of the at least two carriers.

Specifically, the second measurement configuration information includes measurement configuration information applied to at least two carriers. The first carrier is included in the at least two carriers. And, each of the at least two carriers corresponds to one measurement configuration information. For example, the description will be given by taking the example shown in fig. 4. The second measurement configuration information includes measurement configuration information applied to carriers 1 to 5. The second measurement configuration information may be a measurement interval pattern. One SMTC pattern for each of carriers 1 through 5. The 5 SMTC patterns may be understood as first measurement configuration information corresponding to each carrier. I.e. the first measurement configuration information for each carrier is different. It should be understood that, although the measurement configuration information corresponding to each of the carriers 1 to 5 is referred to as first measurement configuration information, the content, for example, the period, and the like, included in the 5 pieces of first measurement configuration information are different. Alternatively, the measurement configuration information corresponding to each carrier may be named as different measurement configuration information and may be distinguished by the name. For example, the measurement configuration information corresponding to carriers 1 to 5 may be respectively referred to as: the carrier measurement configuration information includes carrier measurement configuration information No. 1, carrier measurement configuration information No. 2, carrier measurement configuration information No. 3, carrier measurement configuration information No. 4, and carrier measurement configuration information No. 5. The embodiments of the present application are not limited thereto. The first parameter is determined according to the measurement configuration information corresponding to each carrier and the second measurement configuration information in the at least two carriers. For example, the description will be given by taking the example shown in fig. 4. The first parameter is determined according to the measurement interval pattern information and the SMTC pattern information corresponding to 5 carriers, respectively. In other words, the first parameter is determined according to the measurement configuration information corresponding to each of the at least two carriers, the second measurement configuration information applied to the plurality of carriers, and the first measurement configuration information on the first carrier. In this embodiment, the first parameter is determined by using the measurement configuration information corresponding to each carrier and the second measurement configuration information in the at least two carriers, and various measurement configuration information related to the first carrier are fully considered. It is ensured that the differentiated processing is carried out for different carriers. It is realized that the parameters corresponding to different carriers may be different. The fairness and the competitiveness of the measurement opportunities of different carriers are improved.

It is to be understood that the first parameter may also be determined from other measurement configuration information related to the first carrier. The embodiments of the present application are not limited thereto.

Optionally, as an embodiment, the first parameter is determined according to a total number of carriers of the at least two carriers that collide with the first measurement configuration information of the first carrier.

Specifically, the description will be given by taking the example shown in fig. 4. The second measurement configuration information includes measurement configuration information applied to carriers 1 to 5. Assuming that the first carrier is carrier 1, the measurement configuration information of carrier 1 may be the SMTC pattern of carrier 1. It can be seen that the terminal needs to perform the measurement on the carrier 1 according to the second measurement configuration information. But the second measurement configuration information is applied to carriers 2 to 5 at the same time. Therefore, when the carrier 1 is measured, there is a high possibility that the interference with the measurement of the carriers 2 to 5 by the terminal device may occur. For example, signals on carrier 1 are measured according to the second measurement configuration information at the same time, and signals on carriers 2 and 3 are measured according to the second measurement configuration information. It may happen that a measurement collision with the first carrier occurs at the same time. That is, the terminal device measures the first carrier and also measures other carriers at the same time. A measurement conflict may occur. Thus, the first parameter is determined based on a total number of carriers of the at least two carriers that collide with the first measurement configuration information of the first carrier. I.e., the total number of carriers with measurement collisions including the first carrier, at the same time. By determining the first parameter in this manner, it may be more accurately and truly reflected that the first parameter corresponds to the first carrier. The accuracy of the first parameter is improved. So that the first parameter can reflect the fairness and the competitiveness of the measurement opportunities of different carriers more truly.

It should be understood that, in the embodiment of the present application, the first parameter may also be determined according to the first measurement configuration information and the second measurement configuration information, or other configuration information related to the first carrier. The embodiments of the present application are not limited thereto.

Alternatively, in the case that the first parameter is determined according to the number of valid detected carriers of the terminal device, for example, as shown in fig. 4, if the terminal is capable of simultaneously performing SSB measurements on carriers 1 to 5, the first parameter may also be equal to the total number of carriers having collision with carrier 1 minus 4 for carrier 1, i.e. the first parameter may be 1 for carrier 1. Alternatively, for carrier 1, the first parameter may be at least one same total number of carriers minus 4 as the interval in which the measurement window of carrier 1 is located. I.e. the first parameter is 1. It should be understood that, in the case that the first parameter is determined according to the number of effective detected carriers of the terminal device, the minimum value of the first parameter is 1. The network device can configure different measurement configuration information for different terminal devices according to the first parameter reported by the terminal device. The measurement performance and the user experience of the terminal equipment are improved.

Optionally, as an embodiment. The first measurement configuration information includes a measurement window and the second measurement information includes a measurement interval. The impact then includes: the measurement interval of the measurement window on the carrier included in the at least two carriers is at least one same as the measurement interval of the measurement window on the first carrier.

Specifically, the method is described. For each carrier, the first measurement configuration information may include a measurement window (reception window), where the measurement window is configured by the network device and used for notifying the terminal device of a period or a position when receiving on the carrier or measuring the measurement window, and the like. The second measurement configuration information includes a measurement interval. The second measurement configuration information is also configured by the network device, and is used for notifying the terminal device of measurement information and the like when measuring a plurality of carriers. For example, the terminal device may perform cell identification or Measurement operation on the multiple carriers in each Measurement interval (Measurement Gap) notified by the second Measurement configuration information. Then the colliding of the first measurement configuration information with the first carrier of the at least two carriers comprises: the measurement interval of the measurement window on the carrier included in the at least two carriers is at least one same as the measurement interval of the measurement window on the first carrier. I.e. the total number of carriers that need to be measured in the same measurement interval, including the first carrier itself. By using the method to judge whether the collision occurs, the result can be accurately and quickly obtained. The efficiency of determining the first parameter by the terminal equipment is improved.

For example, the description will be given by taking the example shown in fig. 4. The measurement interval period included in the second measurement configuration information is 40ms, and the SMTC periods are 20ms, 40ms, 80ms, 160ms, and 160ms for carriers 1 to 5, respectively. Assume that the first carrier is carrier 1 and the at least two carriers are 5 carriers. The at least two carriers include carrier 1. For carrier 1 itself, the measurement interval of each SSB receive window is the same as that of carrier 1 itself, and carrier 1 itself can be considered to collide with itself. The measurement interval of the second SSB receive window on carrier 2 is within the same measurement interval as the third SSB receive window on carrier 1. Carrier 2 may also be considered to collide with carrier 1. The measurement interval in which the first SSB receive window on carrier 3 is located is within the same measurement interval as the first SSB receive window on carrier 1. Carrier 3 can be considered to collide with carrier 1. The measurement interval of the first SSB receiving window on carrier 4 is within the same measurement interval as the third SSB receiving window on carrier 1. Carrier 4 can be considered to collide with carrier 1. The measurement interval of the first SSB receiving window on carrier 5 is within the same measurement interval as the seventh SSB receiving window on carrier 1. Carrier 5 can be considered to collide with carrier 1. Therefore, of the 5 carriers, the total number of carriers having an impact with the carrier 1 is 5. I.e. for carrier 1 the value of the first parameter is 5.

Similarly, for carrier 2, the SSB window on carrier 2 is measured at {0,1,2,3,4, … }. The SSB window on carrier 3 is measured at 0,2,4,8,10, …. The SSB window on carrier 4 is measured at 1,5,9,13,17, … intervals. The SSB window on carrier 5 is measured at 3,7,11,15,19, … intervals. Correspondingly, the other carriers having the "SSB measurement interval collision" with the carrier 2 are carriers 1, 3,4, and 5, and the value of the first parameter corresponding to the carrier 2 is 5. The other carriers having "SSB measurement interval collision" with the carrier 3 are carriers 1 and 2, and the value of the first parameter corresponding to the carrier 3 is 3. The other carriers having "SSB measurement interval collision" with the carrier 4 are carriers 1 and 2, and the value of the first parameter corresponding to the carrier 4 is 3. The other carriers having "SSB measurement interval collision" with the carrier 5 are 1 and 2, and the value of the first parameter corresponding to the carrier 5 is 3.

Optionally, as an embodiment. The first measurement configuration information comprises a measurement window and the second measurement information comprises a measurement interval; the collision includes at least one measurement window on a carrier included in the at least two carriers being within the same measurement interval as at least one measurement window on the first carrier.

Specifically, the method is described. For each of the plurality of carriers, the first measurement configuration information may include measurement window (reception window) information, the measurement window being configured by the network device to inform the terminal device of a period or a position of the reception or measurement window, and the like. The second measurement information includes a measurement interval and the like. The second measurement configuration information is also configured by the network device, and is used for notifying the terminal device of measurement information and the like when measuring a plurality of carriers. The terminal device may perform cell identification or Measurement operation on the multiple carriers in each Measurement interval (Measurement Gap). Then the colliding of the first measurement configuration information with the first carrier of the at least two carriers comprises: the carrier of the at least two carriers includes at least one measurement window within the same measurement interval as the at least one measurement window on the first carrier. I.e. the same measurement interval, in which the measurement windows of other carriers are present in addition to the first carrier.

For example, the description will be made by taking the example shown in fig. 4. The measurement interval period is 40ms, and the SMTC periods are 20ms, 40ms, 80ms, 160ms, and 160ms for carriers 1 to 5, respectively. Assuming that the first carrier is carrier 1, the at least two carriers include 5 carriers. The at least two carriers include carrier 1, and for carrier 1, the measurement interval in which the first SSB measurement window and the second SSB reception window on carrier 2 are located is within the same measurement interval. Carrier 2 may also be considered to collide with carrier 1. The measurement interval in which the first SSB receive window on carrier 3 is located is within the same measurement interval as the first SSB receive window on carrier 1. Carrier 3 can be considered to collide with carrier 1. The measurement interval of the first SSB receiving window on carrier 4 is within the same measurement interval as the third SSB receiving window on carrier 1. Carrier 4 can be considered to collide with carrier 1. The measurement interval of the first SSB receiving window on carrier 5 is within the same measurement interval as the seventh SSB receiving window on carrier 1. Carrier 5 can be considered to collide with carrier 1. Therefore, of the 5 carriers, the total number of carriers having an impact with the carrier 1 is 5. That is, the total number of carriers having collision with carrier 1 is obtained by adding 1 to the number of carriers (4) having collision with carrier 1, excluding carrier 1, and the value of the first parameter for carrier 1 is 5.

Optionally, as an embodiment. The first measurement configuration information comprises a measurement window and the second measurement information comprises a measurement interval; the collision includes that the measurement intervals in which the measurement windows on the carriers included in the at least two carriers are located are all the same or all overlap with the measurement intervals in which the measurement windows on the first carrier are located.

Specifically, for example, as shown in fig. 4, the measurement interval period is 40ms, and the SMTC periods are 20ms, 40ms, 80ms, 160ms, and 160ms for carriers 1 to 5, respectively. Assuming that the first carrier is carrier 1, the at least two carriers include 5 carriers. The at least two carriers include carrier 1, and each SSB receiving window on carrier 2 is all the same or all overlapping with the time interval in which the receiving window of the SSB on carrier 1 is located. I.e. carrier 2 needs to be measured when measuring carrier 1 during any one measurement interval. Thus, carrier 2 and carrier 1 collide.

Optionally, as an embodiment. The first measurement configuration information comprises a measurement window and the second measurement information comprises a measurement interval; the collision includes that the measurement interval in which the measurement windows on the carriers included in the at least two carriers are located is partially identical or partially overlapping with the measurement interval in which the measurement windows on the first carrier are located.

Specifically, for example, as shown in fig. 4, the measurement interval period is 40ms, and the SMTC periods are 20ms, 40ms, 80ms, 160ms, and 160ms for carriers 1 to 5, respectively. Assuming that the first carrier is carrier 1, the at least two carriers include 5 carriers. The measurement interval of each SSB reception window on carrier 3 is the same or partially overlapping with the measurement interval of the reception window of the SSB on wave 1. For example, during the measurement interval of the second SSB receive window on carrier 1, the SSB receive window measurement on carrier 3 is not needed. I.e., only a portion of the measurement intervals in which all SSB receive windows of carrier 1 are located, carrier 3 also needs to be measured when carrier 1 is measured. Thus, carrier 3 and carrier 1 collide. Similarly, carriers 4 and 5 are also colliding with carrier 1.

It should be understood that if the terminal is configured with a measurement interval that is used for NR carrier measurement and heterogeneous carrier measurement at the same time, these heterogeneous carriers are considered to have "measurement interval clash" with other NR carriers. The heterogeneous carrier includes, but is not limited to, LTE, Evolved Universal Terrestrial Radio Access Network (UTRAN), GSM, High Rate Packet Data (HRPD), and the like. The embodiments of the present application are not limited thereto.

It is also to be understood that the explanation or description of the collision may be of other relevant descriptions, but that the nature of the collision is within the same measurement interval in which the measurement windows of other carriers need to be measured in addition to the first carrier. Therefore, other similar descriptions may be made for the pair of impacts. Are intended to be covered by the scope of this application. The embodiments of the present application are not limited thereto.

Optionally, as an embodiment, the first measurement configuration information includes a measurement window including at least one of a start position of the measurement window, a duration of the measurement window, and a period of the measurement window. The second measurement information includes a measurement interval including at least one of a measurement interval start location, a measurement interval duration, and a measurement interval period.

Specifically, for each carrier, the network device configures corresponding measurement configuration information for notifying the terminal device of information such as the period of measuring or receiving signals on the carrier. Thus, the measurement window further comprises at least one of a measurement window start position, a measurement window duration and a measurement window period. The terminal equipment can really measure when and how long the measurement time is according to the information such as the starting position of the measurement window on each carrier and the duration of the measurement window. Taking the example shown in fig. 3 as an example, the start position of the measurement window corresponds to the start position of the SSB reception window, the duration of the measurement window corresponds to the length of the SSB reception window, and the period of the measurement window corresponds to the SMTC period. The second measurement information includes a measurement interval including at least one of a measurement interval start position, a measurement interval duration, and a measurement interval period. For informing the terminal device that measurements of signals on the multiple carriers can be made within these measurement intervals, etc. The measurement interval starting position is used for the terminal equipment to determine the position of the measurement interval. The measurement interval duration corresponds to the time length of the measurement interval. The measurement interval period corresponds to the length of time between every two measurement intervals. For example as shown in fig. 4. The measurement interval period (measurement interval repetition period) is 40 ms. When the first measurement configuration information and the second measurement configuration information include the above contents, the first measurement requirement determined by the terminal device can be made to reflect the characteristic of the first carrier more accurately and truly. The accuracy of the first parameter and the first measurement requirement is improved. Therefore, the first measurement requirement can more truly reflect the fairness and the competitiveness of the measurement opportunities of different carriers.

It should be understood that the measurement window included in the first measurement configuration information may also include other information related to the measurement window. The second measurement information includes a measurement interval and other information related to the measurement interval, and embodiments of the present application are not limited herein.

Optionally, as an embodiment, in S210, the terminal device determines a first measurement requirement on a first carrier according to first measurement configuration information, second measurement configuration information, and a first parameter of the first carrier, where the determining includes determining, by the terminal device, the first measurement requirement according to the measurement window period, the measurement interval period, and the first parameter on the first carrier.

Specifically, since the first measurement information includes the measurement window period, since the second measurement information includes the measurement interval period. Accordingly, the terminal device may determine the first measurement requirement according to the measurement window period, the measurement interval period and the first parameter on the first carrier. This allows the determined first measurement requirement to more accurately and truly reflect the characteristics of the first carrier. The accuracy of the first measurement requirement is improved. The first measurement requirement can reflect the fairness and the competitiveness of the measurement opportunities of different carriers more truly. On the basis of fully considering the measurement opportunity of each carrier, the measurement delay of the terminal equipment can be reduced. Meanwhile, the method avoids the over-high requirement on the measuring capability of the terminal equipment and reduces the cost of the terminal equipment. The user experience is improved.

Optionally, as an embodiment, the determining, by the terminal device, the first measurement requirement according to the measurement window period, the measurement interval period and the first parameter on the first carrier includes:

the first measurement requirement is determined according to the following equation (1),

S＝R×Max(T1,T2)×A(1)

wherein S is a value of the measurement indicator of the first measurement requirement, R is a constant, T1 is the measurement window period, T2 is the measurement interval period, Max (T1, T2) is the larger value of T1 and T2, and a is the first parameter.

Specifically, the terminal device may calculate the value of the measurement index corresponding to the first measurement requirement according to the above formula (1). R is a constant (corresponding to a coefficient), and the value of R is a positive number. T1 is a measurement window period corresponding to the first carrier included in the first measurement configuration information, and the measurement window periods corresponding to different carriers may be different. T2 is a measurement gap period for the multiple carriers included in the second measurement configuration information. Max (T1, T2) is the larger of T1 and T2, and a is the first parameter corresponding to the first carrier.

The description will be given by taking the example shown in fig. 4. Assuming that the first carrier is carrier 1, the measurement window period of the first carrier is 20ms, i.e. the value of T1 is 20 ms. T2 is the measurement interval period for the 5 carriers included in the second measurement configuration information, i.e., the value of T2 is 40ms for carriers 1 to 5. The value of Max (T1, T2) is 40 ms. According to the above explanation of the first parameter, it can be found that the first parameter corresponding to the carrier is 5. R is a predefined constant. Therefore, according to the values of the parameters, the value of the measurement indicator of the first measurement requirement on the first carrier can be calculated. Similarly, for the carriers 2 to 5, the values of the measurement indexes of the measurement demand corresponding to each carrier can be calculated respectively by using the method described above.

Alternatively, in equation (1), R may represent the number of measurement opportunities required. For example, if the first measurement requirement (measurement index) is cell identification time/delay, then R represents the number of measurement opportunities needed within the time of cell identification. If the first measurement requirement is the detection time of Primary Synchronization Signal (PSS)/Secondary Synchronization Signal (SSS), then R represents the number of measurement opportunities required within the PSS/SSS detection time. If the measurement index is the SSB index detection time, the measurement opportunity number required by the SSB index detection time is represented. If the first measurement requirement is an SSB measurement period, then R represents the number of measurement opportunities required in the time to obtain an SSB measurement. It should be understood that the R values may be the same or different for different carriers. For different measurement indexes, the values of R may be the same or different.

the first measurement requirement is determined according to the following equation (2),

S＝Max(T1,T2)×A(2)

wherein, S is the value of the measurement indicator of the first measurement requirement, T1 is the measurement window period, T2 is the measurement interval period, Max (T1, T2) is the larger value of T1 and T2, and a is the first parameter.

Specifically, in addition to calculating the value of the measurement index corresponding to the first measurement requirement using the above equation (1), the value of the measurement index corresponding to the first measurement requirement may be calculated using equation (2). No constant coefficient is required to correct the calculation. T1 is a measurement window period corresponding to the first carrier included in the first measurement configuration information, and the measurement window periods corresponding to different carriers may be different. T2 is a measurement gap period for the multiple carriers included in the second measurement configuration information. Max (T1, T2) is the larger of T1 and T2, and a is the first parameter corresponding to the first carrier. The calculation method is similar to that described above. For brevity, they are not described in detail herein.

The value of the measurement index of the first measurement requirement is calculated by using the formulas (1) and (2), so that the first measurement requirement can be quickly and accurately obtained, and the efficiency of the terminal equipment for carrying out carrier detection is improved. The user experience is improved.

It should be understood that, in addition to calculating the value of the measurement index of the first measurement requirement using the above equations (1) and (2), other equations may be used, for example, the relationship between S and Max (T1, T2), A, R may also satisfy any possible form of quadratic function, exponential function, and the like. The embodiments of the present application are not limited thereto.

Optionally, as an embodiment, the first measurement configuration information of the first carrier is first measurement configuration information of a synchronization signal block SSB on the first carrier.

Specifically, if the first measurement configuration information of the first carrier is the first measurement configuration information of the SSB on the first carrier, it is as shown in fig. 3 or fig. 4. The first measurement configuration information may be SMTC on the first carrier, the measurement window included in the first measurement configuration information may be an SSB measurement window, and the SSB measurement window may include an SSB measurement window start position, an SBB measurement window duration, an SMTC period, and the like. The measurement interval included in the second measurement configuration information may be an SSB measurement interval, and the measurement interval period may be an SSB measurement interval period.

It should be understood that the first measurement configuration information of the first carrier may also be first measurement configuration information of other reference signals on the first carrier, and the embodiments of the present application are not limited herein.

Optionally, as an embodiment, the first measurement requirement includes: at least one of a cell identification time or delay, a reference signal detection time, a reference signal index detection time, a reference signal measurement period, a radio resource management, RRM, measurement period. For example, the value of the measurement indicator of the first measurement requirement calculated by using the above equations (1) and (2) may be a value of a cell identification time, or a value of some reference signal index detection time, etc. It should be understood that the first measurement requirement may also include other information or indicators. The embodiments of the present application are not limited thereto.

Optionally, as shown in fig. 6, the method 200 further includes:

s230, the terminal device sends the first parameter to the network device.

Specifically, when the first parameter is determined according to the number of effective detected carriers of the terminal device, since the number of effective detected carriers is related to the capability of the terminal device, the number of effective detected carriers corresponding to different terminal devices may be different. Also, for a terminal device, the requirements for different carriers are different, or in other words, the importance of different carriers to the terminal device is different. Therefore, the number of active monitoring carriers corresponding to each carrier may be the same or different. The terminal device may report only the same first parameter for all carriers that need to be measured, or may report the first parameter corresponding to each carrier that needs to be measured. After the network device receives the first parameter. Different first measurement configuration information and second measurement configuration information can be configured for different carriers or different terminal devices according to the first parameter, so that the mode of configuring the first measurement configuration information and the second measurement configuration information is more flexible. And is more targeted.

For example, as shown in fig. 4, if the terminal is capable of performing SSB measurements on carriers 1 to 5 simultaneously, the first parameter may also be equal to the total number of carriers having collisions with carrier 1 minus 4 for carrier 1, i.e. the first parameter may be 1 for carrier 1. Alternatively, for carrier 1, the first parameter may be at least one same total number of carriers minus 4 as the interval in which the measurement window of carrier 1 is located. I.e. the first parameter is 1. It should be understood that, in the case that the first parameter is determined according to the number of effective detected carriers of the terminal device, the minimum value of the first parameter is 1. The network device can configure different measurement configuration information for different terminal devices according to the first parameter reported by the terminal device. The measurement performance and the user experience of the terminal equipment are improved.
