Description

Communication method, device and computer readable storage medium

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a communication method, an apparatus, and a computer readable storage medium.

Background

Compared with the long term evolution (Long Term Evolution, LTE) and long term evolution advanced (Long Term Evolution Advanced, LTE-A) wireless communication systems, the 5G New Radio (NR) wireless communication system is deployed in a higher frequency band, and can acquire a larger communication bandwidth. However, higher frequency bands result in greater path loss and penetration loss, making the coverage performance of NR far inferior to LTE and LTE-a. For the uplink of NR, the transmit power of the User Equipment (UE) is limited by regulations and is far lower than that of the network device, so that the uplink coverage performance loss of NR is more serious and needs to be enhanced.

In order to enhance uplink coverage performance of a New air interface (NR), 3GPP proposes a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) technology across multi-Slot transport blocks (Transport Block over Multi-Slot, TBoMS) in Release 17 research phase. The technique can aggregate small packets on each time slot into one large packet and complete the transmission of the large packet on multiple time slots. Packet header overhead can be reduced by packet aggregation, cyclic redundancy code overhead can be reduced by reducing the number of Transport Block (TB) segmentation, coding gain can be improved by increasing the Transport Block size (Transport Block Size, TBs), power spectral density can be improved by reducing the number of physical resource blocks (Physical Resource Block, PRB), and finally the purpose of enhancing NR uplink coverage can be achieved.

In BG selection for PUSCH transmission, the target code rate of TBoMS PUSCH is configured by the network device. When the scaling factor is smaller than the number of slots, the actual code rate of TBoMS PUSCH transmission is smaller than the target code rate, which may result in a higher probability of UE selecting base map (BG) 1 than BG2. Further, since BG2 has a higher coding gain than BG1, performance is deteriorated.

Detailed Description

In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

The definitions of technical terms that may appear in the embodiments of the present application are given below. The terminology used in the description section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

(1) Cross multi-Slot transport block (Transport Block over Multi-Slot, TBoMS)

In order to enhance uplink coverage performance of NR, 3GPP proposed TBoMS physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) technology in Release17 research phase. The technique aggregates small packets on each time slot into a large packet and completes the transmission of the large packet on multiple time slots. Packet header overhead can be reduced by packet aggregation, cyclic redundancy code overhead can be reduced by reducing the number of Transport Block (TB) segmentation, coding gain can be improved by increasing the Transport Block size (Transport Block Size, TBs), power spectral density can be improved by reducing the number of physical resource blocks (Physical Resource Block, PRB), and finally the purpose of enhancing NR uplink coverage can be achieved.

It is proposed on 3GPP RAN1#106-e conference that the intermediate parameter of TBS calculation of TBoMS PUSCH transmission-information bit N _info The calculation formula of (2) is as follows:

N _info ＝K·N _RE ·R·Q _m ·v

wherein N is _RE Represents the number of Resource Elements (RE) on a slot, R represents the code rate, Q _m Representing modulation order, v represents the number of multiple-Input multiple-Output (MIMO) layers, K is a scaling factor, representing the aggregation of TBs over K slots into one large TB. Meanwhile, the number N of slots allocated to TBoMS PUSCH transmission indicates that a TB aggregating K slots is transmitted over N slots, where the number N of slots and the scaling factor K satisfy the condition: K.ltoreq.N, which means that the number of slots for TB aggregation and the number of slots for TB transmission may be the same or different. Referring to fig. 1, fig. 1 is a schematic diagram of TBoMS PUSCH transmission. As shown in fig. 1 (a), assuming that the uplink and downlink timeslot ratio of the time division duplex (Time Division Duplex, TDD) spectrum is DDSUU, k=n=8, i.e. the TBoMS PUSCH transmission transmits a large TB with 8 timeslots aggregated over 8 uplink timeslots (U). Wherein S represents a flexible time slot, which is also called a special time slot, D represents a downlink time slot, U represents an uplink time slot, and uplink and downlink switching is usually performed in the S time slot, wherein the S time slot comprises a downlink time domain symbol, a flexible time domain symbol and an uplink time domain symbol . As shown in fig. 1 (b), n= 8,K =4, i.e., TBoMS PUSCH transmission transmits a large TB aggregated of 4 slots over 8 uplink slots (U).

(2) TBS determination for PUSCH transmissions

The calculation flow of TBS by Rel-15/16 protocol is summarized as follows, and reference is made to sections 38.214, sections 5.1.3.2 and 6.1.4.2.

Step 1): a User Equipment (UE) determines the number N 'of Resource Elements (REs) allocated to PUSCH transmission in one slot' _RE 。

First determining the number of REs allocated to PUSCH transmissions in a PRB, i.e

Wherein,,

representing the number of sub-carriers in one PRB, < +.>

Representing the number of symbols allocated to PUSCH transmission in a slot,/->

Representing the number of REs occupied by DMRS including the overhead of DMRS-RS CDM group and excluding data within the time range of scheduling PUSCH transmission within one PRB, +.>

Representing the overhead configured by the higher layer parameters.

UE determines the total RE number N allocated to PUSCH transmission _RE

N _RE ＝min(156，N′ _RE )·n _PRB

Wherein n is _PRB Indicating the number of allocated PRBs.

Step 2): the number of unquantized temporary information bits satisfies:

N _info ＝N _RE ·R·Q _m ·v

wherein R represents code rate, Q _m The modulation order is denoted, and v denotes the number of MIMO layers.

If N _info 3824 or less, performing the step 3); otherwise, step 4) is performed.

Step 3): when N is _info And at a temperature of 3824, TBS is determined according to the following procedure.

Find closest and not less than N 'according to Table 1' _info Is a TBS of (C).

Table 1: when N is _info TBS at 3824 or less

Step 4): when N is _info At > 3824, TBS was determined according to the following procedure.

Quantized temporary information bit number

Wherein the method comprises the steps of

round represents four inclusive rounding. />

If R is less than or equal to 1/4,

if N' _info ＞8424，

Otherwise the first set of parameters is selected,

(3) Base Graph (BG) selection for PUSCH transmission

Referring to fig. 2, fig. 2 is a schematic diagram of a base map selection. As shown in fig. 2, one of the 2 BGs may be selected as a BG of PUSCH transmission according to R and/or TBS. The size of BG1 is 46x68, and the lowest supported code rate is 1/3, so that the method can be mainly used for scenes with higher throughput requirements, higher code rate and longer code length. The BG2 has a size of 42x52, and can be mainly used for scenes with low throughput requirements, low code rate and short code length. If TBS is less than or equal to 292, or TBS is less than or equal to 3824, R is less than or equal to 0.67, or R is less than or equal to 0.25, BG2 is selected; otherwise, BG1 is selected.

In BG selection of PUSCH transmission, a target code rate R of TBoMS PUSCH is configured by a network device, and when the scaling factor is smaller than the number of slots, an actual code rate of TBoMS PUSCH transmission is smaller than the target code rate. The probability of selecting BG1 is higher than BG2, and the performance is deteriorated because the coding gain of BG2 is higher than BG1.

The technical problems to be solved by the embodiments of the present application may include: and under the condition that the scaling factor is smaller than the time slot number, the terminal equipment determines a base map according to the target code rate and/or the transmission block size of the first signal, and then generates the first signal according to the transmission block size of the first signal and the base map. Therefore, BG2 with high coding gain can be selected with higher probability, so that higher coding gain is obtained, and further, the uplink coverage performance can be enhanced.
