Description

User equipment, network equipment and uplink control information transmission method

Technical Field

The present invention relates to communications technologies, and in particular, to a user equipment, a network device, and an uplink control information transmission method.

Background

In order to improve the broadband and data transmission rate of the communication system, Long Term Evolution (LTE) 8 th edition (Release 8, Rel-8 for short) and 9 th edition (Release 9, Rel-9 for short) of the third generation partnership Project (3rd generation partnership Project, 3GPP) are sequentially enhanced, and Long Term Evolution-Advanced (LTE-a) 10/11/12/13 th edition (Release 10/11/12/13, Rel-10/11/12/13 for short) and more Advanced editions are proposed. The LTE-a system improves the system bandwidth and the data transmission rate by using a Carrier Aggregation (CA) technique.

In an LTE-a system, a network device may configure simultaneous transmission to enable an uplink control channel and an uplink data channel of a User Equipment (UE) to perform frequency division multiplexing in a subframe. If the network device does not configure simultaneous transmission and Uplink Control Information (UCI for short) of the Uplink Control channel needs to be transmitted simultaneously, the UE multiplexes Uplink Control Information (UCI) of the Uplink Control channel to the Uplink data channel for transmission. The UE may map a part of the uplink control information to a preset time-frequency resource of the uplink data channel, then map uplink data according to another time-frequency resource in the uplink data channel other than the preset time-frequency resource, and then punch a part of data on the other time-frequency resource of the uplink data channel by using another part of the uplink control information, so as to map the another part of the uplink control information.

In the LTE-a system, the CA technology makes the number of bits of the uplink control information fed back to the base station by the UE be larger, which makes the mapping of the UE to the other part of information in the uplink control information cause more punctured data, and makes the data loss be serious.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The scheme of the embodiment of the invention can be applied to the Rel-10/11/12/13 of LTE-A and the LTE-A system of more advanced version technology which are proposed by sequentially enhancing Rel-8 and Rel-9 based on LTE, and UE carries UCI through an uplink data channel, thereby realizing multiplexing of uplink control information and data on the uplink data channel when simultaneous transmission is not configured.

Example one

The embodiment of the invention provides UE. Fig. 1 is a schematic structural diagram of a UE according to a first embodiment of the present invention. As shown in fig. 1, the UE 100 may include: a mapping module 101 and a sending module 102.

The mapping module 101 may be configured to map the UCI to a preset time-frequency resource of the uplink data channel, and map the uplink data to other time-frequency resources outside the resource occupied by the preset time-frequency resource and the reference signal on the uplink data channel.

Specifically, in the LTE system, transmission resources are divided according to time and frequency. In the time domain, the largest time unit is a 10ms radio frame, which is divided into 101 ms subframes, each of which is divided into two 0.5ms slots (slots). For the case of adding a Normal Cyclic Prefix (NCP), one slot consists of 7 Orthogonal Frequency Division Multiplexing (OFDM) symbols; for the case of an Extended Cyclic Prefix (ECP), one slot consists of 6 OFDM symbols. In the frequency domain, every 12 subcarriers constitute a Resource Element (RE) of 180 kHz.

The smallest element of a time-frequency resource is a RE, which is a two-dimensional resource consisting of one subcarrier in frequency and one OFDM symbol duration in time. 1 Resource Block (RB) is a Resource Block of 12 subcarriers in a slot frequency domain in a time domain. For NCP, one RB contains 84 time-frequency resource elements RE, and for ECP, one RB contains 72 time-frequency resource elements RE.

The 1 RB pair consists of two RBs consisting of 12 subcarriers in frequency and one subframe in time. For NCP, one RB pair contains 168 time-frequency resource elements REs, and for ECP, one RB pair contains 144 time-frequency resource elements REs. The schematic diagram of the attached drawings of the invention is 1 RB pair or N RB pairs as no special description.

Optionally, the UCI may be control information to be transmitted by a Physical uplink control Channel (PUCCH for short) in a Physical uplink Channel. The UCI may be channel information obtained by the UE performing measurement on a downlink or feedback whether downlink reception is correct, or the like. The UE maps the UCI to the preset time-frequency resource of the uplink data channel and sends the time-frequency resource to the network device, so that the network device can control downlink transmission according to the UCI to ensure downlink data transmission.

The uplink data Channel may be a Physical uplink shared Channel (PUSCH for short) in the Physical uplink Channel. The preset time-frequency Resource includes a time-domain Resource corresponding to at least one Resource Element (RE for short) of the uplink data channel, which is determined by the UE according to a preset parameter.

The mapping module 101 is configured to map the UCI to the preset time-frequency resource of the uplink data channel, and may be configured to fill the UCI into each RE of the preset time-frequency resource. The mapping module 101 may perform mapping of the UCI according to an order of information bits in the UCI and/or a time-frequency order of REs of the preset time-frequency resource. The mapping module 101 may also adopt other manners, such as not according to any order, as long as the UCI is mapped to each RE of the preset time-frequency resource.

The mapping module 101 may be configured to fill the uplink data into each RE of other time frequency resources except the resource occupied by the preset time frequency resource and the reference signal on the uplink data channel. The mapping module 101 may perform mapping on the uplink data according to an order of information bits in the uplink data and/or a time-frequency order of REs of the other time-frequency resources. The mapping module 101 may also adopt other manners, such as not according to any sequence, as long as the uplink data is mapped to each RE of the predetermined time-frequency resource.

The Reference Signal may include a Demodulation Reference Signal (DMRS). The Reference Signal may include at least one of a DMRS and a Sounding Reference Signal (SRS).

The sending module 102 is configured to send the UCI and the uplink data on the uplink data channel.

The sending module 102 may send the UCI and the uplink data to the network device on the uplink data channel of an uplink carrier. The uplink carrier may be at least one of at least two uplink carriers of the UE. The at least two uplink carriers of the UE may include: one Primary Component Carrier (PCC) and at least one Secondary Component Carrier (SCC).

For example, if the UE is in a carrier aggregation scenario of the Rel-10 based LTE-a system, the number of uplink carriers of the UE may be at most 5, that is, the UE may have at most 5 uplink carriers, where one uplink carrier is a PCC and the rest are SCCs. In this scenario, the sending module 102 may send the UCI and the uplink data to the network device on the uplink data channel of the PCC, thereby implementing concurrent transmission of the UCI and the uplink data on the uplink data channel.

For example, if the UE is in a carrier aggregation scenario of the Rel-13 based LTE-a system, the number of uplink carriers of the UE may be at most 32, that is, the UE may have at most 32 uplink carriers, where one uplink carrier is a PCC and the rest are SCCs, or some uplink carriers are PCCs (CCs carrying PUCCH) and the rest are SCCs. In this scenario, the sending module 102 may send the UCI and the uplink data to the network device on the uplink data channel of the PCC and/or the at least one SCC, so as to implement concurrent transmission of the UCI and the uplink data on the uplink data channel.

The UE provided in the first embodiment of the present invention may map the UCI to the preset time-frequency resource of the uplink data channel through the mapping module, then map the uplink data to other time-frequency resources outside the resource occupied by the preset time-frequency resource and the reference signal on the uplink data channel, and then send the UCI and the uplink data on the uplink data channel through the sending module, so as to avoid data loss caused by puncturing the uplink data, and ensure integrity of the uplink data.

Example two

The second embodiment of the invention also provides the UE. Optionally, in the method of the second embodiment, the mapping module 102 may be configured to map the uplink data on the uplink data channel on the time-frequency resources outside the resources occupied by the preset time-frequency resources and the reference signals by performing rate matching on the uplink data on the time-frequency resources outside the resources occupied by the preset time-frequency resources and the reference signals on the uplink data channel.

Optionally, the UCI includes: at least one of Hybrid Automatic Repeat reQuest (HARQ) feedback information, Rank Indicator (RI) information, and channel Indicator information. Wherein the channel indication information includes: at least one of Channel Quality Indicator (CQI) information, Precoding Matrix Indicator (PMI) information, and Precoding Type Indicator (PTI) information.

The RI information and the Channel indication information are generally referred to as Channel State Information (CSI). The HARQ feedback information may include Acknowledgement/Negative Acknowledgement (a/N) information.

The UCI may further include Scheduling Request (SR) information.

If the UCI comprises: HARQ feedback information; the preset time frequency resource may include: a time frequency resource started from one end of an in-band frequency domain corresponding to a first symbol in a subframe where the uplink data channel is located; wherein the first symbol comprises adjacent symbols of two symbols corresponding to the DMRS in the subframe.

The mapping module 101 is further configured to map the HARQ feedback information to a time-frequency resource starting at one end of the in-band frequency domain corresponding to the first symbol in the subframe.

Optionally, the subframe in which the uplink data channel is located is a subframe corresponding to a resource allocated to the UE by the network device. For example, for dynamic scheduling, if FDD, the base station sends a scheduling grant command in N subframes, indicating that resources of N +4 subframes are allocated to the UE; if the TDD is adopted, the base station sends a scheduling permission command in N subframes to indicate that resources of N + k subframes are allocated to the UE, wherein k is 4, 5, 6 and 7, and different values are allocated to different TDD ratios; for TTI bundling or SPS scheduling, multiple subframes may be occupied. The in-band may be a bandwidth of the system bandwidth outside the guard bandwidth. One end of the in-band frequency domain may be an end corresponding to the highest frequency or the lowest frequency of the in-band frequency domain. The frequency domain width of the preset time frequency resource may be determined according to the bit size of the UCI.

The uplink data channel is carried in subframes, wherein each subframe may include: two slots. Each slot includes the same number of symbols. If in the NCP case, each slot in the subframe may include 7 symbols. If in the ECP case, each slot in the subframe may include 6 symbols.

Due to the two symbols corresponding to the DMRS, the adjacent symbols of the two symbols corresponding to the DMRS include: the adjacent symbol of either of the two symbols.

Fig. 2 is a schematic time-frequency diagram of mapping the UCI in an uplink data channel under the NCP condition in the second embodiment of the present invention. As shown in fig. 2, if NCP is the case, the subframe may have 0-13 symbols and 14 symbols. Where symbols 0-6 are symbols of a first slot and symbols 7-14 are symbols of a second slot. Then, the two symbols corresponding to the DMRS may be symbol 3 and symbol 10. The adjacent symbols of the two symbols corresponding to the DMRS include: symbol 2, symbol 4, symbol 9 and symbol 11. That is, if in the NCP case, the first symbol may include symbol 2, symbol 4, symbol 9, and symbol 11. The mapping module 101 maps the HARQ feedback information in the frequency domain wideband of the first symbol in the subframe, for example, the frequency domain wideband may be started from one end of the in-band frequency domain, and the number of REs required for HARQ, which is determined according to the bits of the HARQ feedback information, is determined by the number of carriers of the HARQ feedback information on each symbol. In fig. 2, only one end of the lowest frequency of the in-band frequency domain is illustrated as an example. In fig. 2, the HARQ feedback information is represented by a/N.

Fig. 3 is a schematic time-frequency diagram of mapping the UCI in an uplink data channel under the ECP condition in the second embodiment of the present invention.

As shown in fig. 3, if in the ECP case, there may be 12 symbols from 0 to 11 in the subframe. Where symbols 0-5 are symbols of a first slot and symbols 6-11 are symbols of a second slot. Then, the two symbols corresponding to the DMRS may be symbol 2 and symbol 8. The adjacent symbols of the two symbols corresponding to the DMRS include: symbol 1, symbol 3, symbol 7, and symbol 9. That is, if in the ECP case, the first symbol may include symbol 1, symbol 3, symbol 7, and symbol 9. The frequency-domain wideband of the first symbol mapped in the subframe by the HARQ feedback information may be, for example, the number of REs required for HARQ, which is determined according to the bits of the HARQ feedback information, starting from one end of the frequency domain in the band, that is, the number of carriers of the HARQ feedback information on each symbol. Fig. 3 illustrates only one end of the lowest frequency of the in-band frequency domain as an example.

If the UCI includes RI information, the preset time-frequency resource includes: a time frequency resource started from one end of an in-band frequency domain corresponding to a second symbol in a subframe where the uplink data channel is located; wherein the second symbol includes a symbol separated by one symbol by two symbols corresponding to the DMRS.

The mapping module 101 is further configured to map the RI information to a time-frequency resource starting at one end of the in-band frequency domain corresponding to the second symbol in the subframe.

As shown in fig. 2, in the NCP case, symbol 3 and symbol 10 are two symbols corresponding to the DMRS. Symbol 3 includes symbol 1 and symbol 5, symbol 10 includes symbol 8 and symbol 12, and thus, the second symbol includes: symbol 1, symbol 5, symbol 8, symbol 12. The frequency-domain wideband mapping of the RI information to the second number in the subframe may be, for example, started from one end of the frequency domain in the band, and the number of REs required for the RI information is determined according to bits of the RI information, that is, the number of carriers of the RI information on each symbol is determined. In fig. 2, only one end of the lowest frequency of the in-band frequency domain is illustrated as an example.

As shown in fig. 3, in the ECP case,

symbols

2 and 8 are two symbols corresponding to the DMRS. Symbol 2 includes symbol 0 and symbol 4, symbol 8 includes symbol 6 and symbol 10, and then the second symbol includes: symbol 0, symbol 4, symbol 6, symbol 10. The frequency-domain wideband mapping of the RI information to the second number in the subframe may be, for example, started from one end of the frequency domain in the band, and the number of REs required for the RI information is determined according to bits of the RI information, that is, the number of carriers of the RI information on each symbol is determined. In fig. 3, only one end of the lowest frequency of the in-band frequency domain is described as an example.

If the UCI includes channel indication information, the predetermined time-frequency resource includes: a time frequency resource started from one end of an in-band frequency domain corresponding to a third symbol in a subframe where the uplink data channel is located; wherein the channel indication information includes: at least one of CQI information, PMI information, PTI information.

The third symbol includes: and other symbols except for the two symbols corresponding to the DMRS, the first symbol and the second symbol. The first symbol comprises adjacent symbols of two symbols corresponding to the DMRS in the subframe; the second symbol includes a symbol separated by one symbol from two symbols corresponding to the DMRS.

The mapping module 101 may be further configured to map the channel indication information to a time-frequency resource starting from one end of the in-band frequency domain corresponding to the third symbol in the subframe.

As shown in fig. 2, if the first symbol in the subframe includes symbol 2, symbol 4, symbol 9 and symbol 11, and the second symbol includes symbol 1, symbol 5, symbol 8 and symbol 12 in the case of NCP, the two symbols corresponding to the DMRS include

symbols

3 and 10. If the uplink data channel under the NCP condition includes an SRS, and a symbol corresponding to the SRS is symbol 13, the third symbol includes: symbol 0, symbol 6, symbol 7. If the uplink data channel under the NCP condition does not include the SRS, the third symbol includes: symbol 0, symbol 6, symbol 7, symbol 13. In fig. 2, the channel indication information is represented by CQI/PMI/PTI. In fig. 2, the uplink data channel including the SRS in the NCP case is described.

As shown in fig. 3, if the first symbol in the subframe includes symbol 1, symbol 3, symbol 7 and symbol 9, and the second symbol includes symbol 0, symbol 4, symbol 6 and symbol 10 in the ECP case, the two symbols corresponding to the DMRS include

symbols

2 and 8. If the uplink data channel includes an SRS under the ECP condition, and a symbol corresponding to the SRS is a symbol 11, the third symbol includes: symbol 5. If the uplink data channel does not include the SRS under the ECP condition, the third symbol includes: symbol 5, symbol 11. In fig. 3, the channel indication information is represented by CQI/PMI/PTI. Fig. 3 illustrates that the SRS is included in the uplink data channel in the ECP case.

It should be noted that the mapping module maps the UCI to the preset time domain resource on the uplink data channel shown in fig. 2 and fig. 3, and the mapping module may be applied to any of the following scenarios: the number of downlink carriers corresponding to the UCI is greater than 5 and less than or equal to 8, greater than 1 RB and less than or equal to 3 RBs of the data resource corresponding to the UE, the number of bits of the HARQ feedback information in the UCI is greater than 2 bits and less than or equal to 4 bits, the number of bits of the CSI in the UCI is greater than 11 bits and less than or equal to 22 bits, and the number of bits of the UCI is greater than 22 bits.

It should be noted that, if the UCI only includes HARQ feedback information, the mapping module 101 maps the HARQ feedback information to a time-frequency resource starting from one end of the in-band frequency domain corresponding to the first symbol in the subframe, for example, after the time-frequency resource starting from one end of the in-band frequency domain corresponding to the first symbol in fig. 2 or fig. 3, the mapping of the entire UCI is completed. If the UCI only includes RI information, the mapping module 101 maps the RI information to the time-frequency resources starting from the end of the in-band frequency domain corresponding to the second symbol in the subframe, for example, the time-frequency resources starting from the end of the in-band frequency domain corresponding to the second symbol in fig. 2 or fig. 3, and the mapping of the entire UCI is completed. If the UCI only includes the channel indication information, the mapping module 101 maps the channel indication information to the time-frequency resources starting from the end of the in-band frequency domain corresponding to the third symbol in the subframe, such as the time-frequency resources starting from the end of the in-band frequency domain corresponding to the third symbol described in fig. 2 or fig. 3, and the entire UCI mapping is completed.

If the UCI includes HARQ feedback information and RI information, or includes HARQ feedback information and channel indication information, or includes HARQ feedback information and RI information and the channel indication information, the mapping module 101 not only maps the HARQ feedback information to the time-frequency resource started by the end of the in-band frequency domain corresponding to the first symbol in the subframe, but also maps the RI information to the time-frequency resource started by the end of the in-band frequency domain corresponding to the second symbol, or maps the channel indication information to the time-frequency resource started by the end of the in-band frequency domain corresponding to the third symbol, or maps the RI information to the time-frequency resource started by the end of the in-band frequency domain corresponding to the second symbol, and maps the channel indication information to the time-frequency resource started by the end of the in-band frequency domain corresponding to the third symbol. If the UCI includes RI information and channel indication information, the mapping module 101 not only maps the RI information to the time-frequency resource started by the end of the in-band frequency domain corresponding to the second symbol, but also maps the channel indication information to the time-frequency resource started by the end of the in-band frequency domain corresponding to the third symbol.

Optionally, if the number of resource units required by the channel indication information is greater than the number of resource units corresponding to the third symbol, the preset time-frequency resource further includes: the first symbol and/or the second symbol in the subframe correspond to a time-frequency resource starting from the other end of the in-band frequency domain.

The mapping module 101 is further configured to map the channel indication information to a time-frequency resource starting from the other end of the in-band frequency domain corresponding to the first symbol and/or the second symbol in the subframe.

Optionally, the mapping module 101 may map information bits exceeding the maximum bit number carried by the number of resource units corresponding to the third symbol in the channel indication information to the time-frequency resource starting at the other end of the in-band frequency domain corresponding to the first symbol and/or the second symbol in the subframe.

As shown in fig. 4, in the NCP case, the first symbol in the subframe includes symbol 2, symbol 4, symbol 9, and symbol 11, and the second symbol includes symbol 1, symbol 5, symbol 8, and symbol 12. If one end of the in-band frequency domain is the lowest frequency end of the in-band frequency domain, the other end of the in-band frequency domain is the highest frequency end of the in-band frequency domain; if the one end of the in-band frequency domain is the highest frequency end of the in-band frequency domain, the other end of the in-band frequency domain is the lowest frequency end of the in-band frequency domain. Fig. 4 illustrates that one end of the in-band frequency domain is the lowest frequency end of the in-band frequency domain, and the other end of the in-band frequency domain is the highest frequency end of the in-band frequency domain. The channel indication information is represented by CQI/PMI/PTI in fig. 4. Fig. 4 illustrates that the uplink data channel includes the SRS in the NCP case.

As shown in fig. 4, the mapping module 101 maps information bits of the channel indication information, which exceed the maximum bit number carried by the number of resource units corresponding to the third symbol, to the time-frequency resources starting from one end of the highest frequency in the in-band frequency domain corresponding to the first symbol and/or the second symbol, i.e., symbol 2, symbol 4, symbol 9, symbol 11, and/or symbol 1, symbol 5, symbol 8, symbol 12 in the subframe.

Fig. 5 is a schematic time-frequency diagram illustrating mapping of the UCI in an uplink data channel under another ECP condition in the second embodiment of the present invention. As shown in fig. 5, in the ECP case, the first symbol in the subframe includes symbol 1, symbol 3, symbol 7 and symbol 9, and the second symbol includes symbol 0, symbol 4, symbol 6 and symbol 10. If one end of the in-band frequency domain is the lowest frequency end of the in-band frequency domain, the other end of the in-band frequency domain is the highest frequency end of the in-band frequency domain; if the one end of the in-band frequency domain is the highest frequency end of the in-band frequency domain, the other end of the in-band frequency domain is the lowest frequency end of the in-band frequency domain. Fig. 5 illustrates that one end of the in-band frequency domain is the lowest frequency end of the in-band frequency domain, and the other end of the in-band frequency domain is the highest frequency end of the in-band frequency domain.
