Method for determining channel state information transmission resources, user equipment and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for determining channel state information transmission resources, a user equipment, and a base station.

Background

In an LTE (Long Term Evolution ) wireless communication system, aperiodic CSI (Channel State Information) is transmitted through a physical uplink shared Channel PUSCH, and a base station eNodeB triggers a user equipment UE to report the aperiodic CSI through downlink control Information DCI for scheduling uplink data. An information field exists in DCI for scheduling uplink data and is used for triggering aperiodic CSI reporting, and when the information field indicates that UE needs to report aperiodic CSI, the UE reports the aperiodic CSI at a predefined position through a PUSCH.

At present, with the development of mobile communication service demand, organizations such as ITU (International Telecommunication Union) and 3GPP (3rd Generation Partnership Project) are beginning to research New wireless communication systems (e.g., 5G NR, 5Generation New RAT, fifth Generation New access technology).

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Aiming at the problem that the CSI resource mapping mechanism in LTE can not be applied to determine the CSI transmission resource on the PUSCH without service data transmission in the existing 5G NR, the invention provides a method for determining the channel state information transmission resource, which determines the transmission resources respectively used by two parts of CSI on the PUSCH without service data transmission and ensures the normal transmission of the CSI.

As shown in fig. 1, a method for determining channel state information transmission resources according to an embodiment of the present invention includes:

step 101, receiving downlink control information sent by a base station, where the downlink control information indicates that user equipment has no service data transmission on a physical uplink shared channel PUSCH and reports channel state information CSI, where the CSI includes a first part of CSI and a second part of CSI, the first part of CSI includes rank indication information and part of information in supplemental information, the second part of CSI includes remaining part of information in the supplemental information, and the supplemental information includes at least one of channel quality indication information CQI, precoding matrix information PMI, channel state information reference signal resource indication CRI, and number indication of nonzero width amplitude coefficients on each transmission layer;

step 102, determining transmission resources of the first partial CSI and the second partial CSI on the PUSCH without service data transmission according to the available resource units on the PUSCH and the respective bit number and code rate offset value of the first partial CSI and the second partial CSI.

Through the above steps, the method for determining channel state information transmission resources of the embodiment of the present invention is applied to a user equipment, and first, downlink control information DCI sent by a base station is received, where the DCI indicates that the user equipment does not have service data transmission on a PUSCH and reports CSI (the CSI includes a first part CSI and a second part CSI, the first part CSI includes rank indication information RI and part information in supplemental information, and the second part CSI includes remaining part information in the supplemental information, specifically, the supplemental information includes at least one of CQI, PMI, CRI, and number indication of nonzero width amplitude coefficients on each transmission layer), and the user equipment can know a CSI reporting requirement of the base station on itself through the DCI; and then the user equipment can determine the transmission resources of the first part of CSI and the second part of CSI on the PUSCH without service data transmission according to the available resource units on the PUSCH and the respective bit number and code rate deviation value of the first part of CSI and the second part of CSI, so that the user equipment can report the CSI to the base station through the corresponding transmission resources on the PUSCH without service data transmission, the correct transmission of the CSI on the PUSCH in the 5G NR is ensured, and the performance of the system is further ensured.

Specifically, step 102 includes:

according to the formula

Wherein the content of the first and second substances,

a represents the number of bits of the first partial CSI,

a code rate offset value representing the second partial CSI,

representing the number of the available resource units;

Here, it should be noted that the available resource elements REs on the PUSCH often refer to idle REs except for REs occupied by preset information such as demodulation reference signals DMRS, acknowledgement information ACK/NACK, etc. on the PUSCH without traffic data transmission. For example, when the base station indicates that the user equipment has no service data transmission on the PUSCH through the DCI and reports the CSI (aperiodic), the base station allocates 14 orthogonal frequency division multiplexing OFDM symbols and 2 resource blocks RB to the PUSCH for the current service data transmission, where the DMRS occupies the 3rd blockOne OFDM symbol, the number of available REs on the current PUSCH

And 312 (14-1) × 12 × 2 ═ 312. Assuming that the bit number A of the first partial CSI (CSI part1) is 50 bits, the code rate offset value relative to the PUSCH transmission

Is 5; bit number B of the second partial CSI (CSI part2) is 100 bits, and code rate offset value relative to PUSCH transmission

Is 2. Then by the formula

The number of REs needed for obtaining the CSI part1 is as follows:

and (4) respectively. Thereafter, further from the obtained

Bonding of

Determining the number of REs required by the CSI part2 according to the difference between the two

Preferably, the first and second liquid crystal materials are,

continuing with the above example, the process continues,

and (4) respectively. As such, the resource usage of CSI part1 and CSI part2 on PUSCH without traffic data transmission is as shown in fig. 2, where left slash shading indicates REs transmitting CSI part1, cross-bar shading indicates REs transmitting CSI part2, and dot shading indicates REs occupied by DMRS.

However, it should also be understood that there are situations where the available REs on the PUSCH cannot satisfy the resource usage of CSI part1 and CSI part2, and therefore, to ensure reporting of the CSI critical information, CSI part1 including the rank indication information RI and the partial information in the supplemental information is transmitted preferentially. Configuring the maximum code rate value of the CSI part1 for the ue by the base station, and preferably using the maximum code rate value of the CSI part1 as a preset code rate threshold. Therefore, on the basis of the above embodiment, the method further comprises:

Here, the number of REs required to obtain CSI part1 is first determined

Then, the actual code rate C of the CSI part1 is calculated^CSI-1：

Wherein Q_MIndicating the modulation order. Then, the obtained C is subjected to^CSI-1Comparing with a preset code rate threshold, and then further judging according to a comparison result: if C^CSI-1If the available RE on the PUSCH cannot meet the use of the CSI part1 and CSI part2 resources, the CSI part2 is discarded to ensure the transmission of the CSI part 1; if the actual code isRate C^CSI-1If the number of the available REs on the PUSCH is smaller than or equal to the preset code rate threshold, it can be known that the available REs on the PUSCH can satisfy the use of both the CSI part1 and CSI part2 resources, and the determining step of the number of REs required for CSI part2 transmission is continuously performed.

For example, when the base station indicates, through the DCI, that the user equipment does not transmit the service data on the PUSCH and reports the CSI (aperiodic), the base station allocates 14 OFDM symbols and 1 resource block RB to the PUSCH without transmitting the service data this time, where the DMRS occupies the 3rd OFDM symbol, and then the number of available REs on the current PUSCH is equal to the number of available REs on the PUSCH

And (4) respectively. Assuming that the bit number A of the CSI part1 is 50 bits, the code rate offset value relative to the PUSCH transmission

Is 5; bit number B of CSI part2 is 100 bits, and code rate offset value relative to PUSCH transmission

Is 2. Then by the formula

The number of REs needed for obtaining the CSI part1 is as follows:

and (4) respectively. And the base station configures the maximum code rate value of the CSI part1, namely the preset code rate threshold value, of 0.25 to the user equipment, Q_MFor 2, after determining the number of REs in CSI part1, the actual code rate of CSI part1 is also calculated:

comparing the code rate with a preset code rate threshold, if the actual code rate of the CSI part1 is known to be greater than the preset code rate threshold, discarding the CSI part2, and making the REs transmitting the CSI part1 on the PUSCH be all available REs on the PUSCH, that is, all 156 available REs on the PUSCH are used for transmitting the CSI part1, thereby ensuring the reporting of the CSI key information.

Then, on the basis of the above embodiment, the method further includes:

Here, the determined number of REs for transmitting CSI part1 and the determined number of REs for transmitting CSI part2 are allocated to the PUSCH without traffic data transmission to transmit CSI part1 or CSI part1 and CSI part2, and the CSI is transmitted correctly on the PUSCH without traffic data transmission to ensure the performance of the NR system.

For the condition that the number of REs of the CSI part1 and the number of REs of the CSI part2 are determined, corresponding RE transmission CSI part1 and CSI part2 are distributed on the PUSCH without service data transmission; for the case where only the number of REs of CSI part1 is determined, and CSI part2 is discarded, the available REs on PUSCH without traffic data transmission will all be used for transmitting CSI part 1.

In summary, in the method for determining CSI transmission resources according to the embodiments of the present invention, after knowing the CSI reporting requirement of the base station on the base station through the received DCI, the transmission resources of the CSI part1 and the CSI part2 on the PUSCH without service data transmission are determined according to the available REs on the PUSCH, and the bit numbers and the code rate offset values of the CSI part1 and the CSI part2, so that the user equipment can report the CSI to the base station through the corresponding transmission resources on the PUSCH without service data transmission, thereby ensuring correct transmission of the CSI on the PUSCH in the 5G NR and further ensuring the performance of the system.

As shown in fig. 3, an embodiment of the present invention further provides a method for determining channel state information transmission resources, including:

step 301, predicting the bit number of a second part of CSI according to the bit number of a first part of CSI in the CSI and a preset bit number range of the second part of CSI; the first partial CSI comprises rank indication information and partial information in supplementary information, and the second partial CSI comprises the rest information in the supplementary information, wherein the supplementary information comprises at least one of channel quality indication information (CQI), Precoding Matrix Information (PMI), channel state information reference signal resource indication (CRI) and number indication of nonzero width amplitude coefficients on each transmission layer;

step 302, determining transmission resources of the first part of CSI and the second part of CSI on a PUSCH without service data transmission according to available resource elements on a physical uplink shared channel PUSCH and respective bit numbers and code rate offset values of the first part of CSI and the second part of CSI;

step 303, receiving CSI on the PUSCH without traffic data transmission according to the transmission resources of the first partial CSI and the second partial CSI on the PUSCH without traffic data transmission.

According to the above steps 301 to 303, the method for determining CSI part transmission resources according to the embodiment of the present invention is applied to a base station, and first, the bit number of CSI part2 is predicted by combining the bit number of CSI part1 in CSI and the preset bit number range of CSI part2, so that the base station can also determine transmission resources of CSI part1 and CSI part2 on a PUSCH without service data transmission according to an available RE on the PUSCH, and the bit number and the code rate offset value of each of CSI part1 and CSI part2, and finally, accurately receive CSI on the PUSCH without service data transmission, thereby ensuring the performance of an NR system.

The CSI part1 includes RI and part information of the supplemental information, and the CSI part1 includes the remaining part information of the supplemental information, where the supplemental information includes at least one of CQI, PMI, CRI, and an indication of the number of nonzero width amplitude coefficients per transmission layer.

In addition, the preset CSI part2 bit number range corresponds to the CSI part1 bit number, for example, the bit number a1 corresponding to CSI part1, and the preset CSI part2 bit number range is: and X and Y, blind detection can be carried out by respectively predicting the bit number of the CSI part2 to be X or Y.

Optionally, step 302 includes:

according to the formula

Wherein the content of the first and second substances,

a represents the number of bits of the first partial CSI,

a code rate offset value representing the second partial CSI,

representing the number of the available resource units;

Here, the number of resource elements required for transmission of CSI part1 and CSI part2 can be determined by the above steps through the known available REs on PUSCH and the bit number and code rate offset value of each of CSI part1 and CSI part2 (the bit number of CSI part2 is predicted in step 301). The specific implementation is the same as the implementation of the previous embodiment of the method for determining the channel state information transmission resource applied to the ue, and details are not repeated herein.

Certainly, corresponding to the case that the ue discards the CSI part2 and does not perform transmission, in order to simplify the processing flow, in this embodiment of the present invention, the method further includes:

Calculating an actual code rate C of the first partial CSI^CSI-1Wherein Q is_MRepresentation modulationThe order;

Here, the base station will calculate the actual code rate C of CSI part1 after obtaining the number of REs required for CSI part1 transmission^CSI-1Then through C^CSI-1Comparing with a preset code rate threshold, judging whether the user equipment transmits CSI part2 in advance: if C^CSI-1If the code rate is larger than the preset code rate threshold value, determining that the received CSI does not include the CSI part 2; if C^CSI-1And if the number of REs is less than or equal to the preset code rate threshold, the step of determining the number of REs required for transmitting the CSI part2 is executed continuously. Likewise, C^CSI-1The specific calculation is the same as the implementation of the previous embodiment of the method for determining the channel state information transmission resource applied to the ue, and is not described herein again.

Thereafter, step 303 comprises:

Here, CSI part1, or CSI part1 and CSI part2, will be obtained on the PUSCH without traffic data transmission based on the number of REs required for the respective transmissions of CSI part1 and CSI part2 determined above.

Specifically, for the case that the number of REs in CSI part1 and the number of REs in CSI part2 are both determined, corresponding REs on PUSCH without service data transmission are acquired to CSI part1 and CSI part 2; for the case where only the number of REs of CSI part1 is determined and CSI part2 is discarded, only CSI part1 can be acquired on PUSCH without traffic data transmission.

In summary, the method for determining CSI part2 according to the embodiments of the present invention is applied to a base station, and first predicts the bit number of CSI part2 by combining the bit number of CSI part1 in CSI and the preset bit number range of CSI part2, so that the base station can also determine the transmission resources of CSI part1 and CSI part2 on the PUSCH without service data transmission according to the available REs on the PUSCH, and the bit numbers and the code rate offset values of CSI part1 and CSI part2, and finally accurately receive CSI on the PUSCH without service data transmission, thereby ensuring the performance of the NR system.
