Detailed Description
The invention provides a scheme for realizing pilot frequency measurement suitable for LTE system UE, in the scheme, the UE executes pilot frequency measurement in a certain measurement gap time period, and the key in the process of executing the pilot frequency measurement is how to obtain the measurement gap time period.
The method for obtaining the measurement gap time period provided by the invention comprises the following steps:
(1) before the pilot frequency measurement is executed, the network side allocates resources to a user terminal (user for short) according to a predefined sequence or a predefined formula, and then when the pilot frequency measurement is executed, the user can know the time for executing the pilot frequency measurement according to the resources allocated by the network side, namely the predefined sequence or the predefined formula;
(2) when the pilot frequency measurement is executed, the network side issues measurement gap (measurement gap) information to tell the UE the time for the pilot frequency measurement;
that is, when the inter-frequency measurement needs to be performed, the network side reallocates resources to the user according to a predefined sequence or a predefined formula, and informs measurement gap (measurement gap) information in a measurement indication message sent down, wherein the measurement gap information can represent a certain predefined sequence or a certain formula, and the UE can know the time for performing the inter-frequency measurement according to the measurement gap information;
(3) determining the time for executing pilot frequency measurement according to the resource distributed to the user by the network side;
in this case, the sequence indicating the inter-frequency measurement time is not fixed, that is, the time domain resource allocated to each UE is not arranged according to a certain fixed sequence or a fixed formula, and in this case, the time that can be specifically used for inter-frequency measurement is related to a specific resource scheduling algorithm, that is, the time for the UE to perform the inter-frequency measurement is determined according to the idle time in the time domain resource allocated to the UE by the network side.
As can be seen from the various implementations of determining the time for performing inter-frequency measurement described in (1) to (3) above, the case of measuring gap may be considered or may not be considered when the network side schedules resources. For different situations, the UE will implement the inter-frequency measurement operation in different processing manners. In the two implementation manners of (1) and (2), the time allocated to each UE for inter-frequency measurement may be the same or different, and the time allocated to a certain UE in each radio frame for inter-frequency measurement or the time allocated to a certain UE for service transmission may be the same or different, and at this time, the UE only needs to determine the time for performing inter-frequency measurement according to the allocated time for inter-frequency measurement or the time allocated to service transmission.
In the present invention, the network side may specifically trigger the pilot frequency measurement processing procedure of the ue, for example, the network side implements the triggering operation through the measurement indication message issued, where the measurement indication message includes: the system message may be a message sent by the network side when the UE is in an idle state or a connected state, and the measurement control message is a control message sent by the network side when the UE is in the connected state and used for triggering measurement operation.
In the present invention, the pilot frequency measurement processing procedure may also be triggered by the user equipment itself, for example, the user in an idle state may start the pilot frequency measurement operation according to the needs of the user.
In order to facilitate a further understanding of the invention, several specific implementations of the invention are described below with reference to the accompanying drawings.
Example one
In the embodiment, before performing inter-frequency measurement, resource scheduling processing is performed for the UE, that is, corresponding time domain resources are allocated to the UE, in the resource allocation process, time for the UE to perform the inter-frequency measurement is considered, and then, when the UE needs to perform the inter-frequency measurement, the time for the UE to perform the inter-frequency measurement is determined according to the allocated time domain resources, and corresponding inter-frequency measurement operation is performed.
The specific implementation process of this embodiment is shown in fig. 1, and specifically includes the following steps:
step 11: a network side schedules downlink resources for UE, namely time domain resources are distributed for the UE according to a certain predefined sequence or a certain predefined formula;
in the predefined sequence or the predefined formula, since the time information for the UE to perform the inter-frequency measurement is considered in the resource scheduling process, the UE can know the time available for the inter-frequency measurement in a certain measurement period through the sequence or the formula;
the predefined formula is mainly determined according to the size of TTI (transmission time interval) or/and the manner of identification data, and it is also necessary to have a formula indicating or the network side indicating at what time the UE can start to perform inter-frequency measurement or/and at what time to start transmission of service data, so that the UE can determine the starting time for specifically starting to perform the inter-frequency measurement;
the predefined sequence is mainly determined according to the requirement of minimum gap (gap) or/and service type or/and service volume, and when the network side determines the predefined sequence, it needs to explain when the UE starts transmission of service data or when the UE starts inter-frequency measurement, so that the UE determines the start time for specifically starting to perform inter-frequency measurement;
in the LTE system, the possible representation manners of the predefined sequence include: each frame or each subsequence (a subsequence may be formed by one or more radio frames) is provided with a time available for inter-frequency measurement, for example, in fig. 2 and 3, a radio frame or a subsequence has a time of 4ms for transmission of traffic data, and other times can be used for performing inter-frequency measurement operation, the representation manner of the 4ms may be two representation manners as shown in fig. 2 and 3, where fig. 2 represents that the time of 4ms can be represented in an exploded manner, and fig. 3 represents that the time of 4ms cannot be represented in different manners:
step 12: the network side issues a measurement indication message and starts the pilot frequency measurement;
the measurement indication message comprises: system messages or dedicated measurement control messages, etc., and the information carried in the messages may include: at least one item of information of the same-frequency adjacent cells and the different-frequency adjacent cells, information of the same-layer adjacent cells and information of different-layer adjacent cells;
step 13: the UE determines the time for executing the pilot frequency measurement according to a known sequence or formula;
step 14: the UE carries out pilot frequency measurement at the time when the pilot frequency measurement can be carried out;
step 15: when the UE determines to end the inter-frequency measurement, the UE notifies the network side that the inter-frequency measurement process is ended, which is an optional step, that is, the UE may end the processing process of the inter-frequency measurement in other manners.
Example two
In the embodiment, when the pilot frequency measurement needs to be performed, the network side allocates a corresponding time domain resource to the UE, and in the resource allocation process, the time for the UE to perform the pilot frequency measurement is considered, and then the UE determines the time for the UE to perform the pilot frequency measurement according to the allocated time domain resource and performs a corresponding pilot frequency measurement operation.
The embodiment comprises the following steps in the specific implementation process:
firstly, a network side issues a measurement indication message, such as a system message or a special measurement control message, so as to start a pilot frequency measurement process;
the information carried in the measurement indication message may include: at least one of same-frequency neighbor cell information, information of different-frequency neighbor cells, neighbor cell information, same-layer neighbor cell information, different-layer neighbor cell information, and measurement gap information;
the determination principle of the measurement gap information may be as follows: allocating time domain resources to users according to a certain sequence or a certain formula;
secondly, after receiving the measurement indication message, the UE determines the time for executing pilot frequency measurement according to the measurement gap information;
thirdly, when the time for executing the pilot frequency measurement arrives, corresponding pilot frequency measurement is started to be executed;
optionally, after the pilot frequency measurement is finished, the UE may also report information of finishing the pilot frequency measurement process to the network side, so that the network side determines that the pilot frequency measurement process of the UE is finished.
EXAMPLE III
In this embodiment, the network side does not consider the time of the inter-frequency measurement in the time domain resource allocated to the UE, so when the UE needs to perform the inter-frequency measurement, the time for performing the inter-frequency measurement may be determined according to the idle time in the time domain resource allocated to the UE, so as to perform the inter-frequency measurement.
The embodiment comprises the following steps in the specific implementation process:
firstly, a network side schedules downlink resources including time domain and frequency domain resources for UE;
before the pilot frequency measurement is executed, the network side allocates corresponding time domain resources for the UE, but the time for executing the pilot frequency measurement is not considered in the process of scheduling the resources for the UE;
secondly, when a network side issues a measurement indication message, such as a system message or a special measurement control message, a pilot frequency measurement process is started;
the information carried in the measurement indication message may include: at least one of information of the same-frequency neighboring cell and the different-frequency neighboring cell, information of the same-layer neighboring cell and information of the different-layer neighboring cell;
the measurement indication message does not contain the information of the measurement gap;
thirdly, after receiving the measurement indication message, the UE side demodulates the message and determines that the pilot frequency measurement operation needs to be executed on the adjacent cell according to the indication message of the network side;
since the measurement indication message received by the UE may also be measurement indication information other than the inter-frequency measurement, the subsequent steps in this embodiment are only executed when the measurement indication message indicates that the inter-frequency measurement needs to be performed;
fourthly, the UE determines the time available for inter-frequency measurement according to the time domain resources allocated by the network side, that is, the time domain resources other than the time domain resources allocated to the user may be used for inter-frequency measurement, which specifically may be:
(1) the time vacated by the network side, namely the idle time meets the requirement of executing the pilot frequency measurement, and the UE carries out the pilot frequency measurement in the idle time;
(2) the time vacated by the network side partially meets the requirement for executing the pilot frequency measurement, and partially does not meet the requirement, the UE only utilizes the gap meeting the pilot frequency measurement requirement to carry out the pilot frequency measurement, and abandons the gap not meeting the requirement, namely does not carry out the pilot frequency measurement operation;
(3) if all the time vacated by the network side does not accord with the pilot frequency measurement requirement, the UE reports the situation to the network side, and the network side reallocates resources so as to determine the pilot frequency measurement time according to the reallocated resources and further perform pilot frequency measurement operation;
wherein, the requirement of inter-frequency measurement may be: the requirement of minimum gap, i.e. the minimum value of the gap length for inter-frequency measurement, must be such that the UE can adjust the receiver to the inter-frequency and get synchronized with the target cell.
Example four
In this embodiment, before the UE performs the inter-frequency measurement, the UE is already allocated with resources, and the inter-frequency measurement time is taken into account in the process of scheduling the resources.
The specific implementation process of the embodiment comprises the following steps:
firstly, a network side schedules downlink resources for UE, the time of pilot frequency measurement needs to be considered when scheduling resources in a time domain, and the requirement that the gap length reserved in each frame after scheduling at least needs to be larger than the minimum gap for executing pilot frequency measurement needs to be ensured;
secondly, a network side issues a measurement indication message, such as a system message or a special measurement control message, so as to control the UE to start a corresponding pilot frequency measurement operation;
the information carried in the measurement indication message may include: at least one item of information of the same-frequency adjacent cells and the different-frequency adjacent cells, information of the same-layer adjacent cells and information of different-layer adjacent cells;
thirdly, after receiving the measurement indication message, the UE side demodulates the message and executes the fourth step when determining that the pilot frequency measurement operation needs to be executed on the adjacent cell according to the indication message of the network side;
fourthly, the UE can determine the time for performing pilot frequency measurement according to the known allocated resources, namely the UE performs pilot frequency measurement within the gap time for performing pilot frequency measurement, wherein the gap time is determined according to the gap in each frame of the downlink resources allocated to the UE by the network side.
EXAMPLE five
The specific implementation process of the embodiment comprises the following steps:
firstly, a network side issues a measurement indication message, such as a system message or a special measurement control message, so as to start the pilot frequency measurement operation of the UE;
the information carried in the measurement indication message may include: at least one of information of co-frequency neighbor cells and inter-frequency neighbor cells, information of co-layer neighbor cells, information of inter-layer neighbor cells, and measurement gap information;
the determination principle of the measurement gap information may include: the network side schedules the UE through the known time resource scheduled for the UE, the time required to be scheduled must meet the requirement of the minimum gap for executing pilot frequency measurement, and if a plurality of time resources which can be used for the gap exist in the range of the frame length and part of the gap resources meet the requirement, the network side can issue gap messages meeting the requirement to users, or the network side schedules resources again for the users according to a scheduling algorithm and the requirement of the measurement gap, schedules the time resources meeting the requirement of the measurement gap for the users, or the network side schedules resources again for the users according to a certain formula;
secondly, after receiving the measurement indication message, the UE side demodulates the message, and when determining that the pilot frequency measurement needs to be performed on the adjacent cell according to the indication message of the network side, the third step is performed;
and thirdly, the UE carries out pilot frequency measurement according to the indicated measurement gap.
