Description

Communication transmission method and equipment

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method and apparatus for communication transmission.

Background

During communication transmission, CSI (Channel State Information ) transmission through PUSCH (Physical Uplink Shared Channel ) is supported. In NR (New Radio), the case of carrying CSI on PUSCH includes carrying only SP-CSI (Semi-Persistent Channel State Information ) on PUSCH; or the PUSCH carries only a-CSI (Aperiodic Channel State Information ); or the PUSCH carries the a-CSI and UL-SCH (UpLink-Shared CHannel).

Further, in order to enhance the PUSCH transmission reliability, PUSCH retransmission is also supported. The types of PUSCH repetition transmission may be classified into PUSCH repetition type a and PUSCH repetition type B. The PUSCH repetition type a is a time slot based repetition transmission, and PUSCH is repeated in consecutive time slots. When the PUSCH has the CSI, the terminal equipment only carries out repeated transmission when the PUSCH has the A-CSI and the UL-SCH, and if the PUSCH only carries the CSI, the PUSCH does not carry out repeated transmission and only carries out transmission in the first time slot. The PUSCH repetition type B is characterized in that the terminal device determines the symbol number of a nominal PUSCH repetition (nominal PUSCH repetition) according to the PUSCH symbol number indicated by the network device and the repetition number K, and the nominal PUSCH repetition end-to-end occupies a plurality of continuous symbols. A nominal PUSCH repetition is segmented when it encounters slot boundaries, uplink and downlink switching, and unavailable symbols, possibly into multiple actual PUSCH repetitions (actual PUSCH repetition). At this time, the number of symbols of one actual PUSCH repetition is smaller than the number of PUSCH symbols of one nominal PUSCH repetition indication.

However, in the PUSCH repetition type a, when there is a-CSI and UL-SCH on the PUSCH, it is not explicitly specified on which PUSCH or PUSCHs the terminal device transmits a-CSI. Furthermore, in the PUSCH repetition type B, there is also no provision provided for the terminal device to transmit CSI on which PUSCH or PUSCHs.

In summary, the current scheme of transmitting CSI on PUSCH repetition is not perfect.

Detailed Description

In the communication transmission process, supporting CSI transmission through a PUSCH. In the NR, the case of carrying the CSI on the PUSCH includes carrying only the SP-CSI on the PUSCH; or the PUSCH only carries the A-CSI; or the a-CSI and UL-SCH are carried on PUSCH.

To enhance PUSCH transmission reliability, PUSCH repetition transmission is supported. For example, in Rel-15 NR, a terminal device repeats PUSCH transmission in a plurality of consecutive slots according to the number of PUSCH repetition times configured by a network device, where such a transmission scheme is referred to as PUSCH repetition type a in NR. For the PUSCH repetition type a, the terminal device only performs repeated transmission on the PUSCH when there are a-CSI and UL-SCH on the PUSCH, and if the PUSCH only carries CSI, the PUSCH does not perform repeated transmission, and only performs transmission in the first slot. However, in the PUSCH repetition type a, when there is no a-CSI and UL-SCH provided on the PUSCH, the terminal device does not have an explicit provision on which PUSCH or PUSCHs the a-CSI is transmitted.

For another example, in Rel-16 NR, PUSCH repetition type B is introduced. The PUSCH repetition type B is characterized in that the terminal device determines the symbol number of a nominal PUSCH repetition (nominal PUSCH repetition) according to the PUSCH symbol number indicated by the network device, and a plurality of nominal PUSCH repetitions occupy a plurality of continuous symbols end to end. A nominal PUSCH repetition is segmented when it encounters slot boundaries, uplink and downlink switching, and unavailable symbols, possibly into multiple actual PUSCH repetitions (actual PUSCH repetition). At this time, the number of symbols of one actual PUSCH repetition is smaller than the number of PUSCH symbols of one nominal PUSCH repetition indication. However, in the PUSCH repetition type B, currently, on which PUSCH or PUSCHs the terminal device transmits CSI has not been specified explicitly.

In order to solve the above-mentioned problems, an embodiment of the present application provides a method for communication transmission, and the technical solution of the embodiment of the present application may be applied to various communication systems, for example: long term evolution (long term evolution, LTE) systems, worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX) communication systems, future fifth generation (5th Generation,5G) systems such as new generation radio access technologies (new radio access technology, NR), and future communication systems such as 6G systems.

The base station may be configured to inter-convert the received air frames with Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network.

Furthermore, the terms "comprising" and "having" in the embodiments of the application and in the claims and drawings are not exclusive. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to only those steps or modules but may include other steps or modules not listed.

In the embodiment of the present application, in the case of PUSCH repetition transmission, there are various methods for determining PUSCH repetition for transmitting CSI, and the method is not limited to the following methods.

Determining a first mode: and the terminal equipment determines one or more PUSCH repetition carrying the CSI according to the priority of the PUSCH.

In the embodiment of the present application, the communication system determines, according to the method of the determining manner, the content of the repetition of one or more PUSCHs carrying CSI, and the steps described in fig. 2 may be referred to.

S200, the terminal device determines the priority of PUSCH.

In the embodiment of the present application, the terminal device may determine the priority of the PUSCH in multiple manners.

For example, the terminal device determines the priority of the PUSCH according to the downlink control information DCI sent by the received network device, where the DCI includes the priority indication of the PUSCH.

For another example, the terminal device determines a preconfigured or predefined PUSCH priority as the PUSCH priority.

S201, the terminal device determines at least one PUSCH repetition for transmitting CSI according to the priority of the PUSCH.

Specifically, in the embodiment of the present application, if the PUSCH is of high priority, the terminal device determines that all PUSCH repetitions are loaded with CSI; and if the PUSCH is of low priority, the terminal equipment selects part of PUSCH repetition from the PUSCH repetition to bear the CSI.

Further, in an optional manner of this embodiment of the present application, if the PUSCH is of low priority, the terminal device selects the first or last PUSCH repetition of the PUSCH repetitions to carry CSI.

In the embodiment of the present application, the terminal device selects the first PUSCH repetition or the last PUSCH repetition of the PUSCH repetition to carry CSI in various manners, and is not limited to the following.

Case 1: and the terminal equipment selects the first or last nominal PUSCH repetition in the PUSCH repetition to bear the CSI.

And when the nominal PUSCH repetition is segmented, the terminal equipment selects all actual PUSCH repetition bearing CSI in the first or last nominal PUSCH repetition.

Case 2: and the terminal equipment selects the first or last actual PUSCH repetition in the PUSCH repetition to bear the CSI.

And S202, the terminal equipment repeatedly transmits the CSI to the network equipment through the at least one PUSCH.

And S203, the network equipment determines the priority of the PUSCH.

And S204, the network equipment repeatedly receives the CSI from the terminal equipment on the at least one PUSCH according to the priority of the PUSCH.

It should be noted that the sequence of steps described in fig. 2 does not constitute a limitation of the embodiment of the present application, for example, the step S203 may occur before the step S200.

The embodiment of the present application is illustrated for the determination mode based on PUSCH repetition type a and PUSCH repetition type B, respectively:

illustratively, as shown in fig. 3, it is assumed that the terminal device receives PUSCH scheduling information of the network device. Wherein, the PUSCH scheduling information indicates PUSCH repetition type a, the PUSCH carries SP-CSI, the number of symbols of the PUSCH l=7, the repetition number k=2, and the PUSCH repetition number starts from symbol #7 of slot n.

Therefore, when the PUSCH is of high priority, the terminal device carries SP-CSI on both PUSCH repetitions, i.e. the terminal device carries SP-CSI on PUSCH repetition numbered #1 and PUSCH repetition numbered # 2.

And when the PUSCH is of low priority, the terminal equipment only carries the SP-CSI on one PUSCH repetition. The specific PUSCH repetition on which the terminal device carries the SP-CSI may be determined according to a rule predefined in the protocol, for example, the terminal device carries the SP-CSI on the first PUSCH repetition, i.e. the terminal device carries the SP-CSI on the PUSCH repetition numbered # 1; or the terminal equipment carries the SP-CSI on the last PUSCH repetition, namely the terminal equipment carries the SP-CSI on the PUSCH repetition numbered # 2.

It should be noted that, in the embodiment of the present application, in fig. 3, a slot is shown to include 14 symbols, numbered from 0 to 13, and in fig. 3, only the first SP-CSI is included, and for brevity of description, other PUSCHs of subsequent periodicity are not included in the figure.

For example, as shown in fig. 4, it is assumed that the terminal device receives PUSCH scheduling information of the base station, where the PUSCH scheduling information indicates PUSCH repetition type B, the PUSCH carries only a-CSI without UL-SCH, the number of symbols of the PUSCH is l=7, and the repetition number is k=2, and starts from the 12 th symbol of the slot n.

In fig. 4, since the first nominal PUSCH repetition crosses the slot boundary, it is segmented into two actual PUSCH repetitions with symbol numbers of 2 and 5, i.e., actual PUSCH repetition numbered #1 and PUSCH repetition numbered #2, respectively, while the second nominal PUSCH repetition is not segmented. That is, fig. 4 shows that the terminal apparatus transmits PUSCH repetition #1 having a symbol number of 2, PUSCH repetition #2 having a symbol number of 5, and PUSCH repetition #3 having a symbol number of 7, respectively, from the 12 th symbol of the slot n.

Therefore, when the PUSCH is of high priority, the terminal device carries a-CSI on all three PUSCH repetitions, i.e. the terminal device carries a-CSI on PUSCH repetition numbered #1, PUSCH repetition numbered #2 and PUSCH repetition numbered #3.

And when the PUSCH is of low priority, the specific PUSCH repetition on which the terminal device carries the a-CSI may be determined according to a rule predefined in the protocol.

For example, if the terminal device selects the first or last nominal PUSCH repetition to carry CSI in the PUSCH repetition, in fig. 4, the terminal device selects the last nominal PUSCH repetition to carry a-CSI, that is, the terminal device carries a-CSI on PUSCH repetition numbered # 3; or the terminal equipment selects a first nominal PUSCH repetition to bear the A-CSI, wherein, as the first nominal PUSCH repetition is segmented, the terminal equipment selects all actual PUSCH repetition bearing CSI in the first nominal PUSCH repetition, namely, the terminal equipment bears the A-CSI on the PUSCH repetition with the number of #1 and the PUSCH repetition with the number of # 2.

For another example, if the terminal device selects the first or last actual PUSCH repetition in the PUSCH repetition to carry CSI, in fig. 4, the terminal device selects the first actual PUSCH repetition to carry a-CSI, that is, the terminal device carries a-CSI on the PUSCH repetition numbered # 1; or the terminal equipment selects the last actual PUSCH repetition to bear the A-CSI, namely the terminal equipment bears the A-CSI on the PUSCH repetition with the number of # 3.

And a second determination mode: and the terminal equipment determines at least one PUSCH repetition of the CSI according to the number of the symbols of the PUSCH.

In the embodiment of the present application, the communication system determines, according to the method described in the second determination mode, the content of the repetition of one or more PUSCHs carrying CSI, and may refer to the steps described in fig. 5.

S500, the terminal equipment determines the actual number of transmission symbols of each PUSCH repetition in the PUSCH repetition.

S501, the terminal device determines at least one PUSCH repetition for transmitting CSI according to the actual number of transmission symbols of each PUSCH repetition.

Specifically, in the embodiment of the present application, the determining, by the terminal device, at least one PUSCH repetition for transmitting CSI according to the actual number of transmission symbols of each PUSCH repetition includes:

And the terminal equipment determines the PUSCH repetition with the largest actual transmission symbol number in the PUSCH repetition as the PUSCH repetition carrying the CSI.

Further, in an optional manner in the embodiment of the present application, the terminal device selects the actual PUSCH repetition carrying CSI with the largest number of symbols in the first or last nominal PUSCH repetition.

In the embodiment of the present application, if there are a plurality of PUSCH repetitions with equal numbers of actual transmission symbols, the terminal device selects one PUSCH repetition with earliest time from the PUSCH repetitions with equal numbers of actual transmission symbols to carry CSI; or if there are multiple PUSCH repetitions with equal numbers of actual transmission symbols, the terminal device carries CSI on the PUSCH repetitions with equal numbers of actual transmission symbols.

S502, the terminal device repeatedly transmits the CSI to the network device through the at least one PUSCH.

S503, the network device determines the number of symbols of the PUSCH.

And S504, the network equipment repeatedly receives the CSI from the terminal equipment on the at least one PUSCH according to the number of symbols of the PUSCH.

It should be noted that the sequence of steps described in fig. 5 does not constitute a limitation of the embodiment of the present application, for example, the step S503 may occur before the step S500.

The embodiment of the application is illustrated based on PUSCH repetition type B for the determination mode two:

for example, as shown in fig. 6, it is assumed that the terminal device receives PUSCH scheduling information of the network device, where the PUSCH scheduling information indicates PUSCH repetition type B, there is UL-SCH and a-CSI on the PUSCH, the number of symbols of the PUSCH is l=7, and the number of repetitions is k=2, and starts from the 12 th symbol of the slot n.

In fig. 6, since the first nominal PUSCH repetition crosses the slot boundary, it is segmented into two actual PUSCH repetitions with symbol numbers of 3 and 4, i.e., actual PUSCH repetition numbered #1 and PUSCH repetition numbered #2, respectively, while the second nominal PUSCH repetition is not segmented. That is, fig. 4 shows that the terminal apparatus transmits PUSCH repetition #1 having a symbol number of 3, PUSCH repetition #2 having a symbol number of 4, and PUSCH repetition #3 having a symbol number of 7, respectively, from the 12 th symbol of the slot n.

Further, on which PUSCH repetition the terminal device specifically carries the a-CSI may be determined according to predefined rules in the protocol.

For example, if the terminal device selects, from all PUSCH repetitions, PUSCH repetition carrying CSI with the largest number of symbols in the actual PUSCH repetition, in fig. 6, the terminal device selects to carry a-CSI on the last PUSCH repetition, that is, the terminal device carries a-CSI on PUSCH repetition with number #3.

For another example, if the protocol agrees that the terminal device selects the PUSCH repetition carrying CSI with the largest number of actual PUSCH repetition symbols in the first nominal PUSCH repetition, in fig. 6, the terminal device selects to carry a-CSI on the second actual PUSCH repetition, i.e. the terminal device carries a-CSI on the PUSCH repetition numbered # 2.

For example, as shown in fig. 7, it is assumed that the terminal device receives PUSCH scheduling information of the network device, where the PUSCH scheduling information indicates PUSCH repetition type B, there is UL-SCH and a-CSI on the PUSCH, the number of symbols of the PUSCH is l=7, and the number of repetitions is k=4, and starts from the 12 th symbol of the slot n.

In fig. 7, the first nominal PUSCH repetition spans the slot boundary and is segmented into two actual PUSCH repetitions with symbol numbers of 2 and 5, i.e., an actual PUSCH repetition numbered #1 and an actual PUSCH repetition numbered #2, and the second nominal PUSCH repetition is not segmented, i.e., a PUSCH repetition numbered # 3. The third nominal PUSCH repetition crosses the slot boundary, is segmented into two actual PUSCH repetitions with symbol numbers of 2 and 5, respectively, namely an actual PUSCH repetition numbered #4 and an actual PUSCH repetition numbered #5, and the fourth nominal PUSCH repetition is not segmented, namely a PUSCH repetition numbered # 6.

For example, the terminal device selects the PUSCH repetition with the largest number of symbols in the actual PUSCH repetition from all PUSCH repetitions to carry CSI. As can be seen from fig. 7, the PUSCH repetition of No. 3 and the PUSCH repetition of No. 6 are 7 symbols.

Therefore, if the protocol agrees that if there are multiple PUSCH repetitions with equal numbers of actual transmission symbols, the terminal device selects one PUSCH repetition with earliest time to carry CSI from the PUSCH repetitions with equal numbers of actual transmission symbols, and according to a predefined rule, the terminal device carries a-CSI on PUSCH repetition with number # 3.

In addition, if the protocol agrees that if there are multiple PUSCH repetitions with equal numbers of actual transmission symbols, the terminal device carries CSI on all PUSCH repetitions with equal numbers of actual transmission symbols, and according to a predefined rule, the terminal device carries a-CSI on both PUSCH repetitions numbered #3 and PUSCH repetitions numbered # 6.

And determining a third mode: and the terminal equipment determines at least one PUSCH repetition of the CSI according to the priority of the PUSCH and the symbol number of the PUSCH.

In the embodiment of the present application, the communication system determines, according to the third method of the determining manner, the content of the repetition of one or more PUSCHs carrying CSI, and may refer to the step in fig. 8.

S800, the terminal equipment determines the priority of the PUSCH.

S801, the terminal device determines an actual number of transmission symbols of each PUSCH repetition in the PUSCH repetitions.

S802, the terminal equipment determines at least one PUSCH repetition of the CSI according to the priority of the PUSCH and the symbol number of the PUSCH.

Specifically, in the embodiment of the present application, the determining, by the terminal device, at least one PUSCH repetition of CSI according to the priority of the PUSCH and the number of symbols of the PUSCH includes:

if the PUSCH is of high priority, the terminal equipment determines that all PUSCH repetition is carried with CSI; or if the PUSCH is of low priority, the terminal device determines at least one PUSCH repetition for transmitting CSI according to the actual number of transmission symbols of each PUSCH repetition.

In an optional manner in this embodiment of the present application, when the terminal device determines at least one PUSCH repetition for transmitting CSI according to the number of actual transmission symbols of each PUSCH repetition, the terminal device may select, in the first or last nominal PUSCH repetition, the actual PUSCH repetition with the largest number of symbols to carry CSI.

In addition, in the embodiment of the present application, if there are a plurality of PUSCH repetitions with equal numbers of actual transmission symbols, the terminal device selects one PUSCH repetition with earliest time from the PUSCH repetitions with equal numbers of actual transmission symbols to carry CSI; or if there are multiple PUSCH repetitions with equal numbers of actual transmission symbols, the terminal device carries CSI on the PUSCH repetitions with equal numbers of actual transmission symbols.

S803, the terminal device repeatedly transmits the CSI to the network device through the at least one PUSCH.

S804, the network device determines the priority of the PUSCH and the number of symbols of the PUSCH.

And S805, the network equipment repeatedly receives the CSI from the terminal equipment on the at least one PUSCH according to the priority of the PUSCH and the number of symbols.

It should be noted that the sequence of steps described in fig. 8 does not constitute a limitation of the embodiment of the present application, for example, the step S801 may occur before the step S800.

The embodiment of the application is illustrated based on the PUSCH repetition type B for the determination mode three:

illustratively, as shown in fig. 4 above, the specific PUSCH repetition on which the terminal device carries the a-CSI may be determined according to predefined rules in the protocol.

For example, when determining that the priority of the PUSCH is high, the terminal device selects to carry the a-CSI on all PUSCH repetitions, i.e. the terminal device carries the a-CSI on PUSCH repetitions numbered #1, numbered #2, and numbered # 3.

For another example, when the terminal device determines that the priority of the PUSCH is low, the terminal device selects, from all PUSCH repetitions, PUSCH repetition with the largest number of symbols in actual PUSCH repetitions to carry CSI, and in fig. 4, the terminal device selects to carry a-CSI on the last PUSCH repetition, that is, the terminal device carries a-CSI on the PUSCH repetition numbered # 3.

In the third determining manner, the terminal device selects, from all PUSCH repetitions, a PUSCH repetition carrying CSI with the largest number of symbols in the actual PUSCH repetition, which is described in detail in the second determining manner, and is not described in detail herein for brevity.

It should be noted that, in the embodiment of the present application, the content of the at least one PUSCH repetition for determining the received CSI by the network device is similar to the content of the at least one PUSCH repetition for determining the transmitted CSI by the terminal device, specifically refer to the description of the terminal device in the first to third determining modes, and are not repeated herein for brevity.
