Description

Communication processing method and related equipment

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a communication processing method and related devices.

Background

In the current communication system, in a case where there is resource overlap in the time domain between a physical uplink control channel (Physical Uplink Control Channel, PUCCH) for transmitting uplink control information (Uplink Control Information, UCI) (e.g., hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) information, etc.) and an uplink shared physical channel (Physical Uplink Shared Channel, PUSCH) for transmitting data, a terminal (UE) may multiplex UCI to be transmitted on the PUCCH for transmission on a PUSCH overlapping the PUCCH.

In the process that the terminal multiplexes UCI on PUSCH and transmits, the modulation symbol corresponding to UCI is usually mapped and transmitted from the next orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol of the demodulation reference signal (Demodulation Reference Signal, DMRS) symbol of PUSCH, that is, UCI is transmitted on PUSCH based on the DMRS of PUSCH. However, the PUSCH overlapped with the PUCCH may not include the DMRS, for example, in order to reduce DMRS overhead to improve PUSCH transmission performance, the DMRS may not be mapped in consecutive partial PUSCH, which may result in degradation of communication performance of the terminal.

As can be seen, there is a problem that the communication performance of the terminal is low because PUSCH overlapped with PUCCH does not include DMRS.

The network side device 12 may be a macro station, an LTE eNB, a 5G NR gNB, etc.; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, etc., or the network side device 12 may be an Access Point (AP); the network-side device 12 may also be a network node formed by a Central Unit (CU) and a plurality of transmission and reception points (Transmission Reception Point, TRP) managed and controlled by the Central Unit. It should be noted that, in the embodiment of the present invention, the specific type of the network side device 12 is not limited.

Referring to fig. 2, an embodiment of the present invention provides a communication processing method, which is applied to a terminal, and as described in fig. 2, the communication processing method includes the following steps:

step 201, executing any one of the following when the first PUSCH overlapping with the first uplink control channel PUCCH does not include the demodulation reference signal DMRS:

In this way, in the case where the PUSCH (i.e., the first PUSCH) overlapping the PUCCH (i.e., the first PUCCH) with resources does not include the DMRS, the terminal performs operations in any one of the above three manners, thereby improving communication performance of the terminal.

In this embodiment, the first UCI may be any UCI, and specifically, the first UCI may include at least one of hybrid automatic repeat request acknowledgement HARQ-ACK information, channel state information (Channel State Information, CSI), and uplink scheduling request (Scheduling Request, SR) SR information.

In the above step 201, in the process of transmitting the first UCI, the terminal may determine whether there is a first PUSCH overlapping with the first PUCCH resource for transmitting the first UCI and excluding the DMRS, and in the case where it is determined that there is a first PUSCH overlapping with the first PUCCH resource and excluding the DMRS, the terminal may perform operations in one to three of the following manners, that is:

mode one, do not multiplex the first UCI for transmission on the first PUSCH;

multiplexing the first UCI on a first PUSCH for transmission, wherein the mapping mode of the first PUSCH for transmitting the first UCI is different from the first mapping mode, and the first mapping mode is a mapping mode of the PUSCH containing the DMRS for transmitting the UCI;

mode three, the first UCI is multiplexed on the second PUSCH and transmitted, and the second PUSCH is a PUSCH including the DMRS.

The overlapping of the PUCCH and PUSCH resources means that the PUCCH resource time and the PUSCH resource time are partially or completely identical.

In this embodiment, the first PUCCH may overlap with some or all of the at least one PUSCH, and the first PUSCH may be one or more PUSCHs that do not include the DMRS in the some or all of the PUSCHs.

For example, as shown in fig. 3, the first PUCCH for transmitting the first UCI overlaps only PUSCH presence resources that do not include DMRS among one of the plurality of PUCCHs (i.e., the first PUSCH includes only one PUSCH); alternatively, the first PUCCH overlaps with at least two PUSCHs of the plurality of puchs, and the at least two PUSCHs include one or more PUSCHs (i.e., the first PUSCH) without DMRS, i.e.,: as shown in fig. 4, the first PUCCH overlaps with two PUSCHs including one PUSCH containing no DMRS; alternatively, as shown in fig. 5, the first PUCCH overlaps with three PUSCHs including one PUSCH not including the DMRS; alternatively, as shown in fig. 6, the first PUCCH overlaps with three PUSCHs including two PUSCHs that do not include DMRS; alternatively, as shown in fig. 7, the first PUCCH overlaps with four PUSCHs including two PUSCHs that do not include DMRS, and so on.

Note that, in the case where the first PUCCH overlaps with some or all of the at least one PUSCH, the at least one PUSCH may be scheduled for transmission of downlink control information (Downlink Control Information), configured grant (Configured grant) for RRC configuration, or the like; in the case where the first PUSCH includes a plurality of PUSCHs, the plurality of PUSCHs included in the first PUSCH may be continuous PUSCHs or discontinuous PUSCHs.

In addition, the at least one PUSCH may be a PUSCH transmitted only once; alternatively, the first PUSCH may be part or all of at least two PUSCHs transmitted at least twice, where the at least two PUSCHs satisfy at least one of the following:

PUSCH, which is a continuous transmission;

the transmitted data blocks are identical;

the DMRS included satisfies a Quasi Co-located (QCL) relationship.

Here, the PUSCH transmitted at least twice is a PUSCH transmitted continuously, which is understood to mean that the PUSCH transmitted at least twice is continuous in time, and different frequency positions may be used in continuous time, that is: in the PUSCH transmitted at least twice, the same or different frequency positions can be used in one PUSCH; the same or different frequency locations may be used between different PUSCHs.

The PUSCH transmitted at least twice may be different in data block for each PUSCH transmission, and is not limited herein.

In the first mode, some information may be transmitted on the first PUSCH, for example, the information may be higher in priority than the first UCI, and the terminal does not multiplex the first UCI for transmission on the first PUSCH, so that in the case that the PUSCH overlapping with the first PUCCH has resources and does not include DMRS, normal transmission of the information to be transmitted by the first PUSCH may be ensured, influence on information transmission on the first PUSCH is reduced, and further communication performance of the terminal is improved.

In some embodiments, in the case where the above is performed without multiplexing the first UCI for transmission on the first PUSCH, the above further includes at least one of:

transmitting the first UCI on the first PUCCH;

and not transmitting the first PUSCH.

Here, in the case that the first PUSCH overlapping with the first PUCCH does not include the DMRS, transmission of the first UCI may be achieved through the first PUCCH, thereby ensuring normal transmission of the first UCI; or, the terminal does not transmit the first PUSCH, so that the resource overhead of the terminal can be saved.

In this embodiment, in the case where the first PUSCH may be part or all of at least two PUSCHs transmitted at least twice (for example, as shown in fig. 3, the first PUSCH is one PUSCH of PUSCHs that are transmitted continuously for a plurality of times and scheduled by one DCI), the first UCI is not multiplexed on the first PUSCH and may be only not transmitted on the first PUSCH or not transmitted.

Alternatively, in some embodiments, the foregoing not multiplexing the first UCI for transmission on the first PUSCH may include:

in the case that the first PUSCH is a part of PUSCHs among PUSCHs of at least two transmissions, not multiplexing the first UCI for transmission on the PUSCH of the at least two transmissions; or alternatively

And not transmitting the PUSCH transmitted at least twice.

Here, the terminal may not multiplex the first UCI on the PUSCH including at least two transmissions of the first PUSCH, or not transmit the PUSCH of at least two transmissions, thereby further improving communication performance of the terminal.

In the prior art, in the case that the PUSCH overlapping with the PUCCH existence resource for transmitting UCI includes DMRS, the terminal multiplexes UCI to be transmitted on the PUCCH on the PUSCH overlapping with the PUCCH existence resource in a first mapping manner, and the first mapping manner is generally that a modulation symbol corresponding to the UCI is mapped from an OFDM symbol of the DMRS symbol of the PUSCH or a neighboring symbol of the DMRS symbol, for example, a next OFDM symbol.

In the second mode, when the first PUSCH does not include the DMRS, the terminal may transmit the first UCI through a second mapping mode different from a mapping mode (i.e., a first mapping mode) of the PUSCH including the DMRS for transmitting UCI, so that UCI to be transmitted on a PUCCH where the PUSCH including no DMRS normally transmits and overlaps with the existing resources may be implemented, resource overhead of the terminal may be saved, and further communication performance of the terminal may be improved.

It should be noted that, the second mapping manner may be a mapping manner preset by the terminal, preconfigured by the network side, or agreed by a protocol, and the terminal may invoke the mapping manner to multiplex the first UCI on the first PUSCH for transmission when the first PUSCH does not include the DMRS.

In addition, the second mapping method may be any mapping method capable of multiplexing the first UCI for transmission on the first PUSCH when the first PUSCH does not include the DMRS, and the mapping method is different from the first mapping method.

In some embodiments, multiplexing the first UCI on the first PUSCH may include: and multiplexing the first UCI on a first symbol in the first PUSCH (i.e., the second mapping manner is that the first UCI is mapped on the first symbol on the first PUSCH) for transmission, where the first symbol is an OFDM symbol determined according to the position of the DMRS included in the third PUSCH.

Here, the terminal may determine the position of the OFDM symbol on the first PUSCH for transmitting the first UCI according to the position of the DMRS in the PUSCH including the DMRS, so that the symbol on the first PUSCH suitable for transmitting the first UCI may be determined, and further, the communication performance of the terminal may be improved. The third PUSCH including the DMRS and the first PUSCH including no DMRS may be PUSCHs of PUSCHs that are continuously transmitted at least twice, and the third PUSCH and the first PUSCH may be adjacent or not adjacent, and are not limited herein.

In addition, the third PUSCH may be any PUSCH that satisfies the preset condition and includes the DMRS in the at least two continuously transmitted PUSCHs, and specifically, the DMRS included in the third PUSCH is closest to the first PUSCH in time, that is, the third PUSCH may be a PUSCH including the DMRS located before the first PUSCH or a PUSCH including the DMRS located after the first PUSCH in the at least two continuously transmitted PUSCHs, so as to enable the terminal to more quickly determine the OFDM symbol used for transmitting the first UCI on the first PUSCH that does not include the DMRS.

In the above embodiment, the DMRS included in the third PUSCH is closest to the first PUSCH in time, and may be understood as an interval between the DMRS in the third PUSCH and the first PUSCH in the time domain, which is closer than an interval between the DMRS in other PUSCHs and the first PUSCH.

In addition, the terminal may determine the first OFDM based on the third PUSCH including the DMRS closest to the first PUSCH in time according to a preset rule, for example, may select an OFDM symbol in the first PUSCH as the first symbol according to a front-back relationship between the third PUSCH and the first PUSCH in the time domain, or may determine the first symbol according to a time interval between the first PUSCH and the DMRS symbol of the third PUSCH, and so on.

In some embodiments, in the case where the third PUSCH is a PUSCH preceding the first PUSCH (i.e., the third PUSCH is a PUSCH including DMRS that is temporally preceding the first PUSCH among PUSCHs of at least two consecutive transmissions), the first OFDM symbol is the first Y OFDM symbols of the first PUSCH, and Y is a positive integer, i.e., Y is an integer greater than or equal to 1; alternatively, in the case where the third PUSCH is a PUSCH located after the first PUSCH (i.e., the third PUSCH is a PUSCH including DMRS located after the first PUSCH in the time domain among PUSCHs of at least two consecutive transmissions), the first OFDM symbol is the last Y OFDM symbols of the first PUSCH.

For example, as shown in fig. 8, PUSCH1, PUSCH2 and PUSCH3 are PUSCHs transmitted three times in succession, and PUSCH1 and PUSCH3 each contain DMRS, PUSCH2 contains no DMRS, and in the case where PUSCH2 (i.e., first PUSCH) overlaps with PUCCH (i.e., first PUSCCH) for transmitting UCI, since PUSCH2 is the closest in time to the DMRS of PUSCH3, the terminal may transmit UCI to be transmitted on the PUCCH on the last 2 OFDM symbols (i.e., y=2) of its 4 OFDM symbols.

In the case where the first symbol includes at least two OFDM symbols (i.e., Y is an integer greater than 1), the terminal multiplexes the first UCI on the first symbol for transmission, and may map the modulation symbols of the first UCI on the at least two OFDM symbols in a time-from-back order, or may map the modulation symbols of the first UCI on the at least two OFDM symbols in a time-from-front order.

In addition, in the case where the first PUSCH includes a plurality of PUSCHs, the terminal may determine OFDM symbols that each PUSCH of the plurality of PUSCHs may be used to transmit UCI, and use the OFDM symbols determined by part or all of the plurality of PUSCHs as the first OFDM.

For example, as shown in fig. 6, the first PUCCH has resource overlapping with two PUSCHs (i.e., the first PUSCH) that do not include DMRS, and the terminal may determine that each PUSCH of the two PUSCHs that do not include DMRS is an OFDM symbol that can be used to transmit UCI, respectively, if the first PUSCH that does not include DMRS is closest to the DMRS included in the previous PUSCH, determine that the first two OFDM symbols that do not include DMRS are OFDM symbols that can be used to transmit UCI; and if the second PUSCH without DMRS is closest to the DMRS included in the next PUSCH, determining that the second two last OFDM symbols without DMRS are OFDM symbols available for transmission of UCI, the terminal may multiplex the first UCI on the first two first OFDM symbols without DMRS or the second two last OFDM symbols without DMRS, or may also transmit the first two first OFDM symbols without DMRS and the second two last OFDM symbols without DMRS.

Note that, the above-mentioned first PUCCH may overlap with a plurality of PUSCHs, and the plurality of PUSCHs may include a PUSCH including a DMRS and a PUSCH including no DMRS, in which case, the terminal may map the first UCI to be transmitted on the PUSCH including the DMRS according to the first mapping manner, and map the first UCI to be transmitted on the PUSCH including no DMRS according to the second mapping manner.

For example, as shown in fig. 8, if there is a resource overlap between the first PUCCH and PUSCH1 and PUSCH2, the terminal may map the modulation symbol corresponding to the first UCI from the OFDM symbol of the DMRS symbol of PUSCH1, and map the modulation symbol corresponding to the first UCI on the second two OFDM symbols of PUSCH 2.

In some embodiments, in a case where multiplexing the first UCI is performed on a first PUSCH, a β -compensation parameter value (i.e., beta-offset) of the first PUSCH is a parameter value indicated by a network side.

Here, the β -compensation parameter value is a parameter value for determining the number of Resource blocks (REs) of UCI in PUSCH and a corresponding code rate, and the β -compensation parameter value of the first PUSCH is indicated by the network side, which may be understood that the β -compensation parameter value of PUSCH without DMRS and the β -compensation parameter value of PUSCH with DMRS are configured independently by the network side, so as to further improve the communication performance of the terminal.

The value of the β -compensation parameter of the PUSCH including no DMRS may be the same value or different from the value of the β -compensation parameter of the PUSCH including DMRS.

Similarly, in the case of performing multiplexing of the first UCI on the first PUSCH, the α (alpha) parameter value of the first PUSCH may be a parameter value indicated by the network, that is, configured independently, where the α parameter value is used to determine the number of REs occupied by the PUSCH after the UCI is multiplexed and the corresponding code rate. It should be noted that the α parameter value may be a scaling (scaling) primer configured for higher layer signaling, and is used to determine the proportion of REs used for transmitting data in PUSCH in scheduled PUSCH-REs.

Preferably, in case of performing multiplexing of the first UCI for transmission on the first PUSCH, the α (alpha) parameter value and the β compensation parameter value of the first PUSCH are calculated based on the corresponding α parameter value and β compensation parameter value of the PUSCH including the DMRS, for example, adding an offset value, a differential value on the basis of the above parameter values; or further multiplying a coefficient based on the parameters, wherein the coefficient is a positive number.

In the third mode, under the condition that the first PUSCH overlapped with the first PUCCH does not include the DMRS, the terminal may multiplex the first UCI on the second PUSCH including the DMRS, so that the first UCI may be ensured to be transmitted on the PUSCH, resource overhead of the terminal is saved, and communication performance of the terminal is improved.

In this embodiment, the second PUSCH may be any PUSCH including a DMRS, and the second PUSCH and the first PUSCH may be PUSCHs in PUSCHs that are continuously transmitted at least twice, for example, in a plurality of PUSCHs including the first PUSCH that are scheduled by one DCI, the terminal may select any PUSCH including a DMRS other than the first PUSCH to transmit the first UCI, and specifically may multiplex the first UCI on a PUSCH transmission including a DMRS next to the first PUSCH.

For example, in the continuously transmitted PUSCH as shown in fig. 3, the PUCCH overlaps only the second PUSCH of the continuously transmitted PUSCH, and the second PUSCH does not include the DMRS, at this time, the terminal may multiplex the DMRS to be transmitted on the PUCCH on the third PUSCH of the continuously transmitted PUSCH, where the third PUSCH includes the DMRS.

In some embodiments, the second PUSCH includes at least one of:

PUSCH of PUSCHs that are continuously transmitted at least twice;

PUSCH satisfying a preset time requirement;

and the PUSCH overlapped with the first PUCCH exists.

Here, the second PUSCH may satisfy at least one of the three conditions, so that the PUSCH selected for transmitting the first UCI and including the DMRS is more suitable, and further, the communication performance of the terminal is improved.

In this embodiment, the second PUSCH includes PUSCH of at least two PUSCHs that are consecutively transmitted, and the second PUSCH and the first PUSCH may be PUSCH of at least two PUSCHs that are consecutively transmitted.

In addition, if the first PUCCH transmission is a HARQ-Ack feedback bit for a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by DCI and there is a resource overlap between the PUSCH scheduled by DCI and the first PUCCH, the time interval between the first OFDM symbol of the first PUCCH and the first OFDM symbol of the PUSCH and the last OFDM symbol of the PDSCH is greater than t_proc, and the starting OFDM symbols of the first PUCCH and the PUSCH are after time S (i.e. the preset time requirement), the terminal may perform transmission of the first UCI multiplexing.

It should be noted that, the second PUSCH includes a PUSCH satisfying a preset time requirement, and may be a part or all of PUSCHs in which the second PUSCH satisfies the preset time requirement; similarly, the second PUSCH includes a PUSCH overlapping with the first PUCCH, and may be a part or all of PUSCHs overlapping with the first PUCCH.

For example, as shown in fig. 4, the first PUCCH overlaps with a second PUSCH and a third PUSCH among PUSCHs continuously transmitted multiple times, and the second PUSCH does not include the DMRS, and the third PUSCH includes the DMRS, the terminal may multiplex the first UCI for transmission on the third PUSCH.

In some embodiments, the second PUSCH may include:

a first PUSCH or all PUSCHs of a plurality of PUSCHs satisfying a preset time requirement among the PUSCHs continuously transmitted at least twice; or alternatively

And in the PUSCHs overlapped with the first PUCCH, one PUSCH or all PUSCHs in a plurality of PUSCHs started by the first PUSCH.

In this embodiment, when there is an overlap between a plurality of PUSCHs including DMRS and a first PUCCH, the terminal may transmit a first UCI on a first PUSCH of a plurality of PUSCHs including DMRS, which is started by the first PUSCH, in the PUSCH overlapped with the first PUCCH.

For example, as shown in fig. 5, if the first PUCCH overlaps with the first PUSCH, the second PUSCH, and the third PUSCH in the continuously transmitted PUSCH, and the first PUSCH and the third PUSCH both include DMRS, and the second PUSCH does not include DMRS, the terminal may multiplex the first UCI on the first PUSCH for transmission.

Alternatively, in the case where there is overlap between a plurality of PUSCHs including DMRS and the first PUCCH, the terminal may also transmit the first UCI on all PUSCHs among the PUSCHs overlapping with the first PUCCH.

For example, as shown in fig. 5, the terminal may multiplex the first UCI for transmission on the first PUSCH and the third PUSCH.

Or, in case that a plurality of PUSCHs among the PUSCHs continuously transmitted at least two times satisfy the preset time requirement, the terminal may transmit the first UCI in a first PUSCH among the plurality of PUSCHs satisfying the preset time requirement among the PUSCHs continuously transmitted at least two times.

For example, as shown in fig. 6, if the first PUSCH of the multiple continuous transmissions contains a DMRS and does not meet the requirement of the timeline (i.e., the preset time requirement), that is, the starting symbol is after S, the third PUSCH and the fifth PUSCH contain the DMRS and meet the requirement of the timeline, the terminal may multiplex the first UCI onto the third PUSCH for transmission.

Or, in the case that a plurality of PUSCHs in the PUSCHs that are continuously transmitted at least twice meet the preset time requirement, the terminal may transmit the first UCI in all PUSCHs in the plurality of PUSCHs that meet the preset time requirement in the PUSCHs that are continuously transmitted at least twice.

For example, as shown in fig. 6, the terminal may multiplex the first UCI onto the third PUSCH and the fifth PUSCH for transmission.

Of course, the second PUSCH may also be a PUSCH that satisfies a preset time requirement and overlaps the first PUCCH, and in a case where a plurality of PUSCHs satisfy a preset time requirement and a PUSCH that overlaps the first PUCCH, the second PUSCH may be the first PUSCH or all PUSCHs of the plurality of PUSCHs.

For example, as shown in fig. 7, in the PUSCHs continuously transmitted for a plurality of times, the third PUSCH and the fifth PUSCH both include DMRS and satisfy the requirement of the time line and overlap with the first PUCCH, and then the terminal may transmit the first UCI on the third PUSCH or may transmit the first UCI on the third PUSCH and the fifth PUSCH.

In the communication process, since the terminal may transmit PUSCH in at least two serving cells simultaneously, and the first PUCCH may overlap with PUSCH resources of any one serving cell in the at least two serving cells, the first PUSCH and the second PUSCH may be PUSCH in the same or different serving cells, that is: in the case where the first PUCCH overlaps with PUSCHs of at least two serving cells, and the first PUSCH is a PUSCH of a first serving cell of the at least two serving cells, the second PUSCH may include: PUSCH in the first serving cell; or PUSCH in a second serving cell, where the second serving cell is a serving cell other than the first serving cell in the at least two serving cells, so that the selection of the second PUSCH is more flexible.

In this embodiment, the second serving cell may be a serving cell other than the first serving cell among the at least two serving cells, and may include one serving cell or a plurality of serving cells.

For example, as shown in fig. 9, if there is an overlap between the first PUCCH and PUSCH on the first serving cell (cell-1) and the second serving cell (cell-2), and the PUSCH of the first serving cell overlapping with the first PUCCH does not include DMRS, the terminal may transmit the first UCI on the PUSCH including DMRS on the second serving cell.

Note that, in the case where the second serving cell includes one serving cell, the second PUSCH may be a PUSCH that satisfies a preset condition and includes a DMRS in the one serving cell, for example, may be a first PUSCH including a DMRS that is temporally after the first PUSCH, or a PUSCH overlapping with the first PUCCH, and so on.

In addition, in the case where the second serving cell includes a plurality of serving cells (e.g., N cells, where N is an integer greater than 1), the second PUSCH may be a PUSCH in some or all of the N cells, for example, a PUSCH including a DMRS in any one of the serving cells, and so on.

In some embodiments, the second serving cell comprises N cells, N being an integer greater than 1;
