Description

Method, device, equipment and storage medium for processing physical channel transmission

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on April 9, 2020, the application number is CN202010274878.X, and the invention title is "Methods, devices, equipment and storage media for processing physical channel transmission", all of which The content is incorporated in this application by reference.

Technical field

The present invention relates to the field of communication technology, and in particular to methods, devices, base station equipment, user equipment, and storage media for processing physical channel transmission.

Background technique

In order to enhance the reliability and robustness of wireless transmission, 5G NR (New Radio) introduces multiple transmission reception points (multiple Transmission Reception Point, referred to as "multi-TRP"), TRP and user equipment for air interface transmission. In the multi-TRP transmission scenario, multiple TRPs can simultaneously serve one user equipment and perform data transmission.

The multi-TRP transmission may include two scenarios: multi-DCI (multi-DCI based, where DCI is the abbreviation of Downlink Control Information (Downlink Control Information)) transmission and single-DCI (single-DCI based) transmission.

In the case of multi-DCI-based transmission, two base station devices can each act as a TRP, and the interaction between them is not timely and send DCI separately. The user equipment can be based on the control resource set (control resource set, abbreviated as " coreset”) to distinguish which TRP the DCI received at this time belongs to.

In the case of single-DCI-based transmission, two base station devices can each act as a TRP, and they can exchange information in time, so that DCI can be sent through one TRP. The DCI contains control information that the two base stations need to issue, such as At this time, one codeword in the Transmission configuration indication field in the DCI can correspond to two transmission configuration indication states (Transmission Configuration Indication state, referred to as "TCI state"), which respectively indicate that the user equipment receives a physical downlink shared channel (Physical Downlink). The direction of the beam of Shared Channel ("PDSCH" for short), or the direction of the beam (beam) of a physical uplink shared channel (Physical Uplink Shared Channel, "PUSCH" for short) sent by the user equipment.

In the scenario of multi-TRP transmission of URLLC services, PDSCH repetition (PDSCH repetition) and PUSCH repetition (PUSCH repetition) are involved.

Regarding PDSCH repetition, the PDSCH repetition scheme 4 (PDSCH repetition scheme 4) of Release 16 of the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") describes the different time slots (slot) For PDSCH repetition, the specific configuration includes that the Transmission configuration indication field in the DCI indicates two TCI states, and the PDSCH-TimeDomainResourceAllocation field includes RepNumR16 (the number of times to indicate PDSCH repetition), and the DMRS port indicated by the Antenna Port(s) field is Come from the same CDM group. According to the configuration of time domain resources, the PDSCH is transmitted on the same symbol position on different slots.

The TCI mapping of multi-TRP PDSCH repetition can be configured as CycMapping or SeqMapping.

SeqMapping indicates that the first TCI state maps the first PDSCH transmission and the second PDSCH transmission, the second TCI state maps the third PDSCH transmission and the fourth PDSCH transmission, and the first TCI state and the second The TCI state maps the remaining PDSCH transmissions in this way.

As shown in Figure 1, TCI state 1 maps the first PDSCH transmission (which is in slot n) and the second PDSCH transmission (which is in slot n+1), and TCI state 2 maps the third PDSCH transmission (which is in slot n+1). The transmission of the fourth PDSCH (within slot n+2) and the fourth PDSCH transmission (within slot n+3) reflect the SeqMapping of the TCI state.

CycMapping indicates that the first TCI state and the second TCI state respectively map the first PDSCH transmission and the second PDSCH transmission, and the first TCI state and the second TCI state map the remaining PDSCH transmissions in this way.

As shown in Figure 2, TCI state 1 maps the first PDSCH transmission (which is in slot n) and the third PDSCH transmission (which is in slot n+2), and TCI state 2 maps the second PDSCH transmission (which is in slot n+2). The transmission of the fourth PDSCH (within slot n+1) and the fourth PDSCH transmission (within slot n+3) reflect the CycMapping of the TCI state.

Regarding PUSCH repetition, it includes PUSCH repetition type A (PUSCH repetition type A) and PUSCH repetition type B (PUSCH repetition type B).

PUSCH repetition type A is described in 3GPP Release 15. The number of PUSCH repeated transmissions can be configured through the high-level parameter pusch-AggregationFactor, and the PUSCH is transmitted on the same symbol position on different slots.

In 3GPP Release 16, PUSCH repetition type A and PUSCH repetition type B are described. For PUSCH repetition type A, the number of PUSCH repetitions can be dynamically indicated through the TDRA table, and the PUSCH is transmitted on the same symbol position on different slots. For PUSCH repetition type B, the nominal transmission times of PUSCH repetition can be dynamically indicated through the TDRA table. Regarding the transmission position of the time domain resource, TDRA indicates the position of the time domain of the first nominal transmission, the next transmission is immediately after the previous transmission; when it encounters downlink symbols, slot boundaries, or invalid symbols (invalid symbol), the nominal transmission will be divided into the actual transmission.

The TCI mapping of multi-TRP PUSCH repetition type A can be configured as SeqMapping or CycMapping. Among them, SeqMapping indicates that the first TCI state maps the first PUSCH transmission and the second PUSCH transmission, the second TCI state maps the third PUSCH transmission and the fourth PUSCH transmission, and the first TCI state and the second PUSCH transmission The two TCI states map the remaining PUSCH transmissions in this way; CycMapping means that the first TCI state and the second TCI state map the first PUSCH transmission and the second PUSCH transmission respectively, and the first TCI state and the second PUSCH transmission The two TCI states map the remaining PUSCH transmissions in this way.

The TCI mapping of multi-TRP PUSCH repetition type B is based on the actual transmitted segment.

As shown in Figure 3, a PUSCH transmission starts from the 3rd symbol, that is, S=3; the number of nominal repetitions is 2, which are the first nominal transmission (Nominal Rep. 1) and the second nominal transmission ( Nominal Rep. 2), that is, K=2; the symbol length L of a nominal repetition is 6 symbols, that is, L=6. Among them, the nominal transmission is divided by the downlink symbol (indicated by "D" in the figure) and the slot boundary, and a total of 4 actual transmissions are obtained, namely: Actual Rep.1, Actual Rep.2, Actual Rep.3, Actual Rep.4 .

In multi-TRP PDSCH repetition, there may be dropping of PDSCH transmission; similarly, in multi-TRP PUSCH repetition, there may be dropping of PUSCH transmission. However, the prior art does not consider the need to increase the transmission gain in these dropping situations.

Detailed ways

In multi-TRP PDSCH repetition, there are multiple situations in which one or more PDSCH transmissions may be dropped or dropped. The remaining valid PDSCH transmission after being dropped can be referred to as real PDSCH transmission.

For example, the PDSCH transmission that conflicts with the uplink symbol may be dropped, and the PDSCH transmission that may collide with the downlink transmission channel in the time domain may be dropped (for example, if the priority of the PDSCH is lower than the priority of the downlink transmission channel, then The former is dropped; for example, if the PDSCH is a PDSCH without PDCCH scheduling and other PDSCHs without PDCCH scheduling collide in the time domain, and the high-level parameter sps-ConfigIndex corresponding to the PDSCH corresponds to a higher identifier, the PDSCH will also be drop), PDSCH transmissions that may be dropped due to collisions with reference signals or uplink transmission channels in the time domain; these valid PDSCH transmissions remaining after being dropped can be called true PDSCH transmissions.

As shown in Figure 4, in the two slots of slot n+2 and slot n+3, there are 1 and 2 uplink symbols (indicated by U) respectively, and the PDSCH on these two slots can be dropped; The remaining valid PDSCH transmissions in the two slots of slot n and slot n+1 are real PDSCH transmissions.

In multi-TRP PUSCH repetition, there are multiple situations where one or more PUSCH transmissions may be dropped. The remaining valid PUSCH transmission after being dropped can be referred to as real PUSCH transmission.

For example, for the first type of PUSCH transmission belonging to PUSCH repetition type A, the PUSCH transmission that conflicts with the downlink symbol may be dropped, and the PUSCH transmission that collides with the uplink transmission channel in the time domain may be dropped (for example, if the PUSCH and The PUCCH that is repeatedly transmitted collides in the time domain, and the PUSCH is discarded), and the PUSCH transmission that may collide with the reference signal or the downlink transmission channel in the time domain may be dropped.

For another example, for the second type of PUSCH transmission belonging to PUSCH repetition type B, the nominal repetition of the PUSCH will be divided into several actual transmissions by the downlink symbol, slot boundary, or invalid symbol; it can be split into PUSCH transmissions with a length of one symbol. PUSCH transmissions that drop collisions with the uplink transmission channel in the time domain and are discarded (for example, if the PUSCH and the repeated PUCCH collide in the time domain, the PUSCH will be discarded), it may drop and the reference signal or the downlink transmission channel PUSCH transmissions that are discarded due to collisions in the time domain.

For another example, the second type of PUSCH transmission belonging to PUSCH repetition type B includes Configured grant PUSCH transmission (that is, semi-static PUSCH transmission and semi-persistent PUSCH transmission). For Configured grant PUSCH transmission, it can be dropped and high-level configured dynamics. The actual PUSCH transmission in which downlink symbols in a slot format indicator (slot format indicator, abbreviated as "SFI") or flexible symbols conflict and are discarded.

The remaining valid PUSCH transmission after being dropped can be referred to as real PUSCH transmission.

As shown in Figure 3, the nominal transmission of PUSCH includes Nominal Rep. 1 and Nominal Rep. 2, which are divided by the downlink symbol D and slot boundary to obtain a total of 4 actual transmissions Actual Rep. 1, Actual Rep. 2, Actual Rep. 3 and Actual Rep. 4, where the length of Actual Rep. 4 is only one symbol, therefore, Actual Rep. 4 can be dropped; after the drop, there are 3 effective actual transmissions: Actual Rep. 1, Actual Rep. 2 and Actual Rep. .3 can be called real PUSCH transmission.

The prior art uses a cyclic mapping method (for example, CycMapping, SeqMapping) to map TCI. When the remaining secondary transmissions (such as secondary PDSCH transmission or secondary PUSCH transmission), based on the cyclic mapping method, the remaining secondary transmissions should correspond to different TCIs.

However, PDSCH transmission or PUSCH transmission may be dropped. In the real transmission that is valid after the drop, the remaining two real transmissions may correspond to the same TCI, that is, the remaining two real transmissions are for the same TRP, for example, both are Transmissions from the same TRP, or transmissions sent to the same TRP, cannot obtain the gain based on two TRP transmissions.

In the embodiment of the present invention, it can be judged whether the TCI state corresponding to the remaining two real transmissions is the same. If they are the same, the other TCI state configured by the higher layer corresponds to the second real transmission in the second real transmission. , So that the remaining two real transmissions come from the transmission of two TRPs to obtain transmission gain.

The embodiment of the present invention can be applied to a multi-TRP scenario. In this scenario, there may be multiple base station devices, each serving as different TRPs.

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 5 is a flowchart of a method 100 for user equipment processing physical channel transmission according to an embodiment of the present invention.

The physical channel can be PDSCH or PUSCH. The physical channel transmission may be PDSCH transmission or PUSCH transmission.

The initial physical channel transmission can be the initial PDSCH transmission or the initial PUSCH transmission, which is the initial configuration without being dropped; if the nominal repetition of the PUSCH is divided, the initial PUSCH transmission is the actual PUSCH after being divided and not being dropped. transmission.

The real physical channel transmission may be real PDSCH transmission or real PUSCH transmission. Regarding real PDSCH transmission and real PUSCH transmission, reference may be made to the above description.

Method 100 includes:

Step S110: Obtain the remaining number of real physical channel transmissions;

Step S120: If the remaining number of times is two, it is judged whether the TCI state corresponding to the two real physical channel transmissions is the same;

Step S130: If the TCI states corresponding to the two real physical channel transmissions are the same, make another TCI state configured by the higher layer correspond to the second real physical channel transmission in the two real physical channel transmissions.

Steps S110, S120 and S130 are executed at the user equipment.

In the execution of step S110, the initial physical channel repetition may include multiple times, and the TCI mapping of the initial physical channel repetition may be based on CycMapping, SeqMapping, and the like. Real physical channel transmission can be obtained after the initial physical channel that is not available for drop is repeated.

In the process of physical channel transmission, the remaining number of real physical channel transmissions can be dynamically obtained.

If the remaining number of times is two, step S120 is executed.

In the execution of step S120, it is determined whether the TCI states corresponding to the two real physical channel transmissions are the same.

In specific implementation, the base station equipment can send DCI on the Physical Downlink Control Channel (PDCCH), and use the TCI state in the DCI to instruct the user equipment to receive PDSCH transmission or send the beam used for PUSCH transmission. , The beams indicated by different TCI states can correspond to different TRPs; the user equipment can receive the TCI state in high-level signaling.

If the TCI states corresponding to the two real physical channel transmissions are the same, step S130 is executed.

Among them, the same TCI state corresponding to the second real physical channel transmission means that the user equipment uses the same beam to receive PDSCH transmission, for example, uses the same beam to receive the second real PDSCH transmission from a TRP; or, the user equipment Use the same beam to send PUSCH transmissions, for example, use the same beam to send two real PUSCH transmissions to a TRP.

In the execution of step S130, another TCI state configured by the higher layer corresponds to the second real physical channel transmission in the second real physical channel transmission.

Among them, the "same TCI state" used as the judgment condition in step S120 may be referred to as "one TCI state", which is different from the above-mentioned "another TCI state".

The base station equipment may send DCI on the PDCCH, and the DCI may include indications of two different TCI states. The user equipment can receive DCI to obtain different TCI states and their corresponding relationships with real physical channel transmissions.

Specifically, the upper layer can configure two different TCI states, which correspond to different beams that the user equipment can use when receiving PDSCH transmissions or sending PUSCH transmissions, and different beams correspond to different TRPs.

After configuring the corresponding relationship between TCI state and real PDSCH transmission at the base station equipment, it can send real PDSCH transmission or receive real PUSCH transmission based on the corresponding relationship, where real PDSCH transmission or real PUSCH transmission has the configuration It also instructs the user equipment to receive PDSCH transmission based on the beam determined by the corresponding relationship; it can also receive real PUSCH transmission based on the corresponding relationship, and the PUSCH transmission sent by the user equipment is based on the corresponding relationship. The determined beam sends PUSCH transmission to the corresponding TRP.

At the user equipment, high-level signaling can be received to obtain different TCI states and their corresponding relationships with PDSCH transmission or PUSCH transmission. The user equipment can receive or send real physical channel transmissions based on the correspondence. For example, the real PDSCH transmission can be received from the corresponding TRP based on the beam determined by the correspondence between the TCI state and the real PDSCH transmission; it can also be sent to the corresponding beam based on the beam determined by the correspondence between the TCI state and the real PUSCH transmission. TRP sends real PUSCH transmission.

By making the remaining two real PDSCH transmissions or PUSCH transmissions correspond to two different TCI states, the user equipment can receive PDSCH transmissions or send PUSCH transmissions based on different beams, thereby obtaining gains based on two TRP transmissions.

The description is given below in conjunction with specific embodiments.

As shown in Figure 6a, the two initial PDSCH transmissions in slot n+2 and slot n+3 have an uplink symbol (indicated by "U"), then the PDSCH on these two slots can be dropped; After the initial PDSCH transmission used, two real PDSCH transmissions are obtained, which are located in slot n and slot n+1 respectively. These two real PDSCH transmissions correspond to the same TCI state (TCI state 1 as shown in the figure).

After the initial PUSCH transmission used, two real PUSCH transmissions are obtained, which are located in slot n and slot n+1 respectively. These two real PUSCH transmissions correspond to the same TCI state (TCI state 1 as shown in the figure).

The PUSCH transmission in slot n can be called the first real PUSCH transmission, and the PUSCH transmission in slot n+1 can be called the second real PUSCH transmission.

When it is determined that the remaining number of real PUSCH transmissions is 2 and their corresponding TCI states are the same (both are TCI state 1), you can make another TCI state configured by the higher layer (TCI state 2 as shown in the figure) corresponds to the second A real PUSCH transmission.
