Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method, apparatus, device, and storage medium. Background Art

[0002] In a mobile communication system, such as a fifth-generation New Radio (NR) system, when there are conflicts between transmission resources of some uplink channels and semi-static downlink symbols, and when there are conflicts between uplink channels with different priorities, it is not clear which uplink channels conflicting with the semi-static downlink symbols need to be cancelled. If there is multi-step multiplexing, it is also not clear whether uplink channels generated during the multiplexing process are needed.

[0003] As Figure 1 shown Figure 1 is a schematic diagram of the distribution of uplink channels within a time slot. There are two Physical Uplink Control Channels (PUCCHs) and Physical Uplink Shared Channels (PUSCHs) (PUCCH-1 and PUCCH-2) with high priority (HP) and a PUCCH with low priority (LP) within a certain time slot, and the conflict situation among them is as Figure 1 shown. Assume that after multiplexing HP PUCCH-1 and HP PUCCH-2, HP PUCCH-3 is obtained, and the transmission resources of HP PUCCH-3 conflict with semi-static downlink symbols. On the one hand, it is not clear whether HP PUCCH-3 will be discarded or multiplexed on HP PUSCH, and on the other hand, it is not clear whether the LP PUCCH that overlaps with HP PUCCH-3 in the time domain will be discarded.

[0004] Therefore, in the absence of a clear channel conflict resolution method, the network device and the terminal device cannot reach an agreement on resolving the above channel conflict problem, which will affect the system transmission performance. Summary of the Invention

[0032] See Figure 2 , Figure 2 is a schematic flowchart of the communication method provided by the embodiments of the present application. The communication method provided by the embodiments of the present application is applicable to terminal devices and / or network devices. As Figure 2 shown, the communication method provided by the embodiments of the present application may include the following steps:

[0033] Step S21: In response to the first low-priority uplink channel and the first high-priority uplink channel in the first time slot satisfying a first condition, determine a second low-priority uplink channel based on the first low-priority uplink channel, and determine a second high-priority uplink channel based on the first high-priority uplink channel.

[0034] In some feasible embodiments, the above-mentioned first time slot may be a time slot or a sub-time slot, which is not limited in the embodiments of the present application.

[0035] In some feasible embodiments, the above-mentioned first condition includes at least one of the following:

[0036] There are uplink channels with overlapping transmission resources in the time domain;

[0037] There are uplink channels with transmission resources conflicting with semi-static downlink symbols;

[0038] There are uplink channels with transmission resources conflicting with Synchronization Signal and PBCH block (SSB) symbols.

[0039] That is, when the first low-priority uplink channel and the first high-priority uplink channel in the first time slot satisfy one or more of the above conditions, a second low-priority uplink channel can be determined based on the first low-priority uplink channel, and a second high-priority uplink channel can be determined based on the first high-priority uplink channel.

[0040] As an example, when there are a first low-priority uplink channel and a first high-priority uplink channel in a time slot, if there are uplink channels with transmission resources conflicting with semi-static downlink symbols and there are uplink channels with overlapping transmission resources in the time domain, a second low-priority uplink channel can be determined based on the first low-priority uplink channel, and a second high-priority uplink channel can be determined based on the first high-priority uplink channel.

[0041] In some feasible embodiments, the above-mentioned first low-priority uplink channel may include at least one of the following:

[0042] Low-priority PUCCH to be transmitted determined based on Downlink Control Information (DCI);

[0043] Low-priority PUSCH to be transmitted determined based on high-layer configuration information.

[0044] As an example, the first low-priority uplink channel in the first time slot in the embodiments of the present application includes the low-priority PUCCH to be transmitted determined based on DCI in the first time slot, and the low-priority PUSCH to be transmitted determined based on high-layer configuration information.

[0045] In some feasible embodiments, the above-mentioned first high-priority uplink channel may include at least one of the following:

[0046] The high-priority PUCCH to be transmitted determined based on DCI;

[0047] The high-priority PUSCH to be transmitted determined based on high-layer configuration information.

[0048] As an example, the first high-priority uplink channel in the first time slot in the embodiments of the present application includes the high-priority PUCCH to be transmitted determined based on DCI in the first time slot, and the high-priority PUSCH to be transmitted determined based on high-layer configuration information.

[0049] In some feasible embodiments, all the uplink channels included in the above-mentioned first low-priority uplink channel are uplink channels before channel multiplexing, and all the uplink channels included in the above-mentioned first high-priority uplink channel are uplink channels before channel multiplexing.

[0050] Step S22: Communicate based on the second low-priority uplink channel and the second high-priority uplink channel.

[0051] In some feasible embodiments, the second low-priority uplink channel and the second high-priority uplink channel are the finally determined uplink channels available for communication.

[0052] Optionally, after determining the second low-priority uplink channel and the second high-priority uplink channel, communication may be performed based on at least one of the second low-priority uplink channel and the second high-priority uplink channel.

[0053] As an example, after determining the second low-priority uplink channel and the second high-priority uplink channel, communication may be performed based on the second low-priority uplink channel and the second high-priority uplink channel. If the terminal device determines the second low-priority uplink channel and the second high-priority uplink channel based on the above method, and the network device determines the same second low-priority uplink channel and the second high-priority uplink channel based on the above method, then the network device and the terminal device may communicate based on the determined second low-priority uplink channel and the second high-priority uplink channel.

[0054] In some feasible embodiments, the determination of the second high-priority uplink channel based on the first high-priority uplink channel includes:

[0055] Cancel the uplink channels that conflict with the semi-static downlink symbols and / or SSB symbols in the transmission resources of the first highest-priority uplink channel, to obtain the third highest-priority uplink channel;

[0056] Determine the second highest-priority uplink channel based on the third highest-priority uplink channel.

[0057] Optionally, the third highest-priority uplink channel can be determined as the second highest-priority uplink channel, that is, the highest-priority uplink channel after canceling the uplink channels that conflict with the semi-static downlink symbols and / or SSB symbols in the transmission resources of the first highest-priority uplink channel is determined as the highest-priority uplink channel that can finally be used for transmission.

[0058] Optionally, the second highest-priority uplink channel can be further determined based on the third highest-priority uplink channel. That is, for the first highest-priority uplink channel, all uplink channels that conflict with the semi-static downlink symbols and / or SSB symbols in the transmission resources of the first highest-priority uplink channel can be canceled, and then the highest-priority uplink channel that can finally be used for transmission is determined from the remaining highest-priority uplink channels.

[0059] Optionally, the first highest-priority uplink channel may also include the highest-priority uplink channel corresponding to the PUCCH overriding process. In other words, in the above-mentioned third highest-priority uplink channel, there may be a highest-priority uplink channel corresponding to the PUCCH overriding process.

[0060] Wherein, when there is a PUCCH resource corresponding to the Hybrid Automatic Repeat Request-Acknowledge (HARQ-ACK) feedback indicated by DCI or configured by Radio Resource Control (RRC) in a time slot, and there is another DCI indicating HARQ-ACK feedback to this time slot and corresponding to a new PUCCH, the highest-priority uplink channel corresponding to the PUCCH overriding process includes the highest-priority uplink channel finally determined by the PUCCH overriding process and the highest-priority uplink channels that appear during the PUCCH overriding process.

[0061] Wherein, the highest-priority uplink channel finally determined by the PUCCH overriding process is the highest-priority PUCCH for HARQ-ACK feedback indicated by the last DCI indicating HARQ-ACK feedback to this time slot. The highest-priority uplink channels that appear during the PUCCH overriding process are the other DCIs or the highest-priority PUCCHs configured by RRC for HARQ-ACK transmission in this time slot except for the DCI corresponding to the highest-priority uplink channel finally determined by the PUCCH overriding process.

[0062] In some feasible embodiments, the above-mentioned first high-priority uplink channel does not include the high-priority uplink channel corresponding to the PUCCH rewriting process. That is, the first high-priority uplink channel only includes at least one of the high-priority PUCCH determined to be transmitted based on DCI or the high-priority PUSCH determined to be transmitted based on high-layer configuration information.

[0063] As an example, the above-mentioned first high-priority uplink channel only includes the high-priority PUCCH determined to be transmitted based on DCI and the high-priority PUSCH determined to be transmitted based on high-layer configuration information. For all high-priority uplink channels within the first time slot, only the uplink channels whose transmission resources conflict with semi-static downlink symbols and / or SSB symbols among the high-priority PUCCH determined to be transmitted based on DCI and the high-priority PUSCH determined to be transmitted based on high-layer configuration information are cancelled to obtain the third high-priority uplink information, so as to determine the second high-priority uplink channel based on the third high-priority uplink channel.

[0064] In some feasible embodiments, after obtaining the third high-priority uplink channel based on the first high-priority uplink channel, the second high-priority uplink channel can be determined based on the third high-priority uplink channel. Specifically, it includes:

[0065] Execute the channel multiplexing process among the third high-priority uplink channels to obtain the fourth high-priority uplink channel. At this time, the fourth high-priority uplink channel includes the uplink channels generated during the channel multiplexing process, the uplink channels finally determined by the channel multiplexing process, and the uplink channels in the third high-priority uplink channels that do not participate in the channel multiplexing.

[0066] For example, if the third high-priority uplink channel includes PUCCH-1, PUCCH-2, and PUSCH, and if the transmission resources of PUCCH-1 and PUCCH-2 overlap in the time domain, then PUCCH-1 and PUCCH-2 can be multiplexed on PUCCH-3. If the transmission resources of PUCCH-3 and PUSCH overlap in the time domain, then the uplink control indicator (UCI) carried by PUCCH-3 can be multiplexed on PUSCH. At this time, the above-mentioned PUCCH-3 is the uplink channel generated during the channel multiplexing process, and the above-mentioned PUSCH is the uplink channel finally determined by the channel multiplexing process.

[0067] Optionally, if the high-priority uplink channel corresponding to the PUCCH rewriting process is included in the first high-priority uplink channel, then execute the channel multiplexing process among the third high-priority uplink channels and the PUCCH rewriting process of the high-priority uplink channel to obtain the fourth high-priority uplink channel.

[0068] At this time, the fourth highest priority uplink channel includes the uplink channels generated during channel multiplexing, the uplink channels finally determined during channel multiplexing, the uplink channels during PUCCH rewriting, the uplink channels finally determined during PUCCH rewriting, and the uplink channels in the third highest priority uplink channel that do not participate in channel multiplexing and PUCCH rewriting.

[0069] Furthermore, after obtaining the above-mentioned fourth highest priority uplink channel, the second highest priority uplink channel can be determined based on the fourth highest priority uplink channel. Specifically, the fourth highest priority uplink channel can be determined as the second highest priority uplink channel, or the second highest priority uplink channel can be determined from the fourth highest priority uplink channel.

[0070] In some feasible embodiments, the determining the second highest priority uplink channel based on the fourth highest priority uplink channel includes:

[0071] Canceling the uplink channels in the fourth highest priority uplink channel where the transmission resources conflict with semi-static downlink symbols and / or SSB symbols to obtain the fifth highest priority uplink channel;

[0072] Determining the uplink channels finally determined during channel multiplexing, the uplink channels finally determined during PUCCH rewriting, and the uplink channels that do not participate in channel multiplexing and PUCCH rewriting in the fifth highest priority uplink channel as the second highest priority uplink channel.

[0073] That is, when determining the second highest priority uplink channel based on the fourth highest priority uplink channel, the uplink channels in the fourth highest priority uplink channel where the transmission resources conflict with semi-static downlink symbols and / or SSB symbols can be canceled first. Then, if there are uplink channels finally determined during channel multiplexing, uplink channels finally determined during PUCCH rewriting, and uplink channels that do not participate in channel multiplexing and PUCCH rewriting among the remaining uplink channels, the uplink channels finally determined during channel multiplexing, uplink channels finally determined during PUCCH rewriting, and uplink channels that do not participate in channel multiplexing and PUCCH rewriting among the remaining uplink channels are determined as the finally available high priority uplink channels for transmission.

[0074] Alternatively, the uplink channels generated during channel multiplexing and the uplink channels during PUCCH rewriting in the fourth highest priority uplink channel can be canceled first, and then the uplink channels in the remaining uplink channels where the transmission resources conflict with semi-static downlink symbols and / or SSB symbols are canceled, and finally the available high priority uplink channels for transmission are obtained.

[0075] In some feasible embodiments, when performing the channel multiplexing process between the third highest priority uplink channels, if there are multiple steps of multiplexing, the transmission resources of the uplink channel generated in each multiplexing process can be determined whether they conflict with the semi-static downlink symbols and / or SSB symbols. If there is a conflict, the uplink channel is immediately cancelled. Based on this method, the transmission resources of the uplink channels generated in the channel multiplexing process included in the fourth highest priority finally obtained do not conflict with the semi-static downlink symbols and / or SSB symbols.

[0076] For example, if the third highest priority uplink channels include PUCCH-1, PUCCH-2, and PUSCH, and the transmission resources of PUCCH-1 and PUCCH-2 overlap in the time domain, PUCCH-1 and PUCCH-2 can be multiplexed on PUCCH-3. At this time, PUCCH-3 is the uplink channel generated in the channel multiplexing process, and then it can be determined whether the transmission resources of PUCCH-3 conflict with the semi-static downlink symbols and / or SSB symbols. If there is a conflict, PUCCH-3 is immediately cancelled. If the transmission resources of PUCCH-3 and PUSCH overlap in the time domain, the UCI carried by PUCCH-3 can be multiplexed on PUSCH to obtain PUSCH.

[0077] Similarly, when performing the PUCCH rewriting process of the high priority uplink channel, the uplink channels in the PUCCH rewriting process whose transmission resources conflict with the semi-static downlink symbols and / or SSB symbols can also be cancelled during the rewriting process, so that the transmission resources of the uplink channels generated in the PUCCH rewriting process included in the fourth highest priority finally obtained based on this method do not conflict with the semi-static downlink symbols and / or SSB symbols.

[0078] As an example, the high priority uplink channels in the first time slot include the high priority PUCCH to be transmitted determined based on DCI before channel multiplexing, the high priority PUSCH to be transmitted determined based on the high layer configuration information, and the high priority uplink channel corresponding to the PUCCH rewriting process.

[0079] Step 1: Cancel the high priority uplink channels whose transmission resources conflict with the semi-static downlink symbols and / or SSB symbols among the other uplink channels except the high priority uplink channel corresponding to the PUCCH rewriting process in all high priority uplink channels.

[0080] Step 2: Perform the channel multiplexing process and the PUCCH rewriting process among the remaining high priority uplink channels in Step 1 to obtain the uplink channels finally determined by the channel multiplexing process, the uplink channels finally determined by the PUCCH rewriting process, and the uplink channels that do not participate in the channel multiplexing and PUCCH rewriting processes.

[0081] Step 3: Cancel the uplink channels in the uplink channels obtained in Step 2 where the transmission resources conflict with the semi-static downlink symbols and / or SSB symbols, and then determine the high-priority uplink channels that can finally be used for transmission from the remaining uplink channels, including the uplink channels finally determined in the channel multiplexing process, the uplink channels finally determined in the PUCCH rewriting process, and the uplink channels that do not participate in channel multiplexing and PUCCH rewriting.

[0082] In some feasible embodiments, determining the second low-priority uplink channel based on the first low-priority uplink channel includes:

[0083] Cancel the uplink channels in the first low-priority uplink channel where the transmission resources conflict with the semi-static downlink symbols and / or SSB symbols to obtain the third low-priority uplink channel;

[0084] Determine the second low-priority uplink channel based on the third low-priority uplink channel.

[0085] Optionally, the third low-priority uplink channel can be determined as the second low-priority uplink channel, that is, the low-priority uplink channel after canceling the uplink channels in the first low-priority uplink channel where the transmission resources conflict with the semi-static downlink symbols and / or SSB symbols is determined as the low-priority uplink channel that can finally be used for transmission.

[0086] Optionally, the second low-priority uplink channel can be further determined based on the third low-priority uplink channel. That is, for the first low-priority uplink channel, all the uplink channels in the first low-priority uplink channel where the transmission resources conflict with the semi-static downlink symbols and / or SSB symbols can be canceled, and then the low-priority uplink channel that can finally be used for transmission is determined from the remaining low-priority uplink channels.

[0087] Optionally, the first low-priority uplink channel further includes the low-priority uplink channel finally determined in the PUCCH rewriting process and does not include the low-priority uplink channels that appear in the PUCCH rewriting process.

[0088] Among them, when there is a PUCCH resource corresponding to the HARQ-ACK feedback indicated by DCI or configured by RRC in a time slot, and there is another DCI indicating HARQ-ACK feedback to this time slot and corresponding to a new PUCCH resource, the low-priority uplink channel finally determined in the PUCCH rewriting process is the low-priority PUCCH for HARQ-ACK feedback indicated by the last DCI indicating HARQ-ACK feedback to this time slot, and the low-priority uplink channels that appear in the PUCCH rewriting process are the high-priority PUCCHs for HARQ-ACK transmission indicated by other DCIs or configured by RRC in this time slot except for the DCI corresponding to the low-priority uplink channel finally determined in the PUCCH rewriting process.

[0089] In some feasible embodiments, after canceling the uplink channels where the transmission resources in the first low-priority uplink channel conflict with the semi-static downlink symbols and / or SSB symbols to obtain the third low-priority uplink channel, a channel multiplexing process between the third low-priority uplink channels can be performed to obtain the fourth low-priority uplink channel.

[0090] Among them, the fourth low-priority uplink channel includes the uplink channels finally determined by the channel multiplexing process and the uplink channels in the third low-priority uplink channel that do not participate in the channel multiplexing.

[0091] In other words, after performing the channel multiplexing process between the third low-priority uplink channels, the uplink channels finally determined in the multiplexing process and the uplink channels in the third low-priority uplink channel that do not participate in the multiplexing process can be determined as the fourth low-priority uplink channel.

[0092] Further, after obtaining the fourth low-priority uplink channel, the second low-priority uplink channel can be determined based on the fourth low-priority uplink channel. Specifically, the fourth low-priority uplink channel can be determined as the second low-priority uplink channel, or the second low-priority uplink channel can be determined from the fourth low-priority uplink channel.

[0093] In some feasible embodiments, after determining the fourth low-priority uplink channel from the first low-priority uplink channel, the uplink channels in the fourth low-priority uplink channel that overlap with the third high-priority uplink channel in the time domain can be canceled to obtain the fifth low-priority uplink channel, and then the second low-priority uplink channel can be determined based on the fifth low-priority uplink channel.

[0094] Among them, the above-mentioned third high-priority uplink channel is obtained after canceling the uplink channels where the transmission resources in the first high-priority uplink channel conflict with the semi-static downlink symbols and / or SSB symbols.

[0095] Further, the second low-priority uplink channel is determined based on the fifth low-priority uplink channel. Specifically, the fifth low-priority uplink channel can be determined as the second low-priority uplink channel, or the second low-priority uplink channel can be determined from the fifth low-priority uplink channel.

[0096] In some feasible embodiments, determining the second low-priority uplink channel based on the fifth low-priority uplink channel includes:

[0097] Determining the second low-priority uplink channel based on the fifth low-priority uplink channel and the fourth high-priority uplink channel.

[0098] Among them, the fourth highest-priority uplink channel is the uplink channel generated in the channel multiplexing process obtained by performing the channel multiplexing process between the above-mentioned third highest-priority uplink channels and the PUCCH rewriting process of the high-priority uplink channel, the uplink channel finally determined by the channel multiplexing process, the uplink channel in the PUCCH rewriting process, the uplink channel finally determined by the PUCCH rewriting process, and the uplink channel in the third highest-priority uplink channel that does not participate in channel multiplexing and PUCCH rewriting.

[0099] Specifically, the uplink channel with time-domain overlap between the transmission resources of the fifth lowest-priority uplink channel and the fourth highest-priority uplink channel can be cancelled to obtain the sixth lowest-priority uplink channel, and the sixth lowest-priority uplink channel can be determined as the second lowest-priority uplink channel, or further, the uplink channel with conflict between the transmission resources of the sixth lowest-priority uplink channel and the semi-static downlink symbol and / or SSB symbol can be cancelled to obtain the second lowest-priority uplink channel.

[0100] In other words, the uplink channel with time-domain overlap between the transmission resources of the fifth lowest-priority uplink channel and the uplink channel generated in the channel multiplexing process obtained by performing the channel multiplexing process between the above-mentioned third highest-priority uplink channels and the PUCCH rewriting process of the high-priority uplink channel, the uplink channel finally determined by the channel multiplexing process, the uplink channel in the PUCCH rewriting process, the uplink channel finally determined by the PUCCH rewriting process, and the uplink channel in the third highest-priority uplink channel that does not participate in channel multiplexing and PUCCH rewriting is cancelled, and the remaining uplink channel is used as the finally available low-priority uplink channel for transmission, or further, the uplink channel with conflict between the transmission resources of the remaining uplink channel and the semi-static downlink symbol and / or SSB symbol is cancelled to obtain the finally available low-priority uplink channel for transmission.

[0101] Optionally, in some feasible embodiments, determining the second lowest-priority uplink channel based on the fifth lowest-priority uplink channel includes:

[0102] Determining the second lowest-priority uplink channel based on the fifth lowest-priority uplink channel and the fifth highest-priority uplink channel.

[0103] Among them, the fifth highest-priority uplink channel is obtained by cancelling the uplink channel with conflict between the transmission resources of the fourth highest-priority uplink channel and the semi-static downlink symbol and / or SSB symbol.

[0104] Specifically, the uplink channel with time-domain overlap between the transmission resources of the fifth lowest-priority uplink channel and the fifth highest-priority uplink channel can be cancelled to obtain the seventh lowest-priority uplink channel, and further, the uplink channel with conflict between the transmission resources of the seventh lowest-priority uplink channel and the semi-static downlink symbol and / or SSB symbol can be cancelled to obtain the second lowest-priority uplink channel.

[0105] In other words, among the uplink channels generated in the channel multiplexing process obtained by performing the channel multiplexing process between the above-mentioned third-highest-priority uplink channels and the PUCCH rewriting process of the high-priority uplink channels, the uplink channels finally determined in the channel multiplexing process, the uplink channels in the PUCCH rewriting process, the uplink channels finally determined in the PUCCH rewriting process, and the uplink channels among the third-highest-priority uplink channels that do not participate in channel multiplexing and PUCCH rewriting, for the uplink channels with time-domain overlapping transmission resources, the uplink channels with transmission resource conflicts with semi-static downlink symbols and / or SSB symbols are cancelled to obtain the fourth-highest-priority uplink channels. Furthermore, based on the fifth-lowest-priority uplink channels and the fourth-highest-priority uplink channels, the second-lowest-priority uplink channels are determined.

[0106] As an example, the high-priority uplink channels in the first time slot include the high-priority PUCCH and / or PUSCH to be transmitted determined based on DCI before channel multiplexing, the high-priority PUCCH and / or PUSCH to be transmitted determined based on high-layer configuration information, and the high-priority uplink channels corresponding to the PUCCH rewriting process. The low-priority uplink channels in the first time slot include the low-priority PUCCH and / or PUSCH to be transmitted determined based on DCI before channel multiplexing, the low-priority PUCCH and / or PUSCH to be transmitted determined based on high-layer configuration information, and the low-priority uplink channels finally determined in the PUCCH rewriting process.

[0107] Step 1: Cancel the low-priority uplink channels with transmission resource conflicts with semi-static downlink symbols and / or SSB symbols among all low-priority uplink channels.

[0108] Step 2: Perform the channel multiplexing process among the low-priority uplink channels obtained in Step 1 to obtain the low-priority uplink channels finally determined in the channel multiplexing process and the low-priority uplink channels that do not participate in channel multiplexing.

[0109] Step 3: Cancel the high-priority uplink channels with transmission resource conflicts with semi-static downlink symbols and / or SSB symbols among the other uplink channels except the high-priority uplink channels corresponding to the PUCCH rewriting process among all high-priority uplink channels.

[0110] Step 4: Cancel the low-priority uplink channels with time-domain overlapping transmission resources between the transmission resources of the low-priority uplink channels obtained in Step 2 and the transmission resources of the high-priority uplink channels obtained in Step 3.

[0111] Step 5: Perform the channel multiplexing process and the PUCCH rewriting process among the remaining high-priority uplink channels in Step 1 to obtain the high-priority uplink channels finally determined by the channel multiplexing process, the high-priority uplink channels finally determined by the PUCCH rewriting process, and the high-priority uplink channels that do not participate in the channel multiplexing and PUCCH rewriting processes, and cancel the uplink channels among the obtained high-priority uplink channels whose transmission resources conflict with the semi-static downlink symbols and / or SSB symbols.

[0112] Step 6: Cancel the uplink channels whose transmission resources in the low-priority uplink channels obtained in Step 4 and the transmission resources of the high-priority uplink channels obtained in Step 5 overlap in the time domain.

[0113] Step 7: Cancel the uplink channels whose transmission resources in the low-priority uplink channels obtained in Step 6 conflict with the semi-static downlink symbols and / or SSB symbols to obtain the finally available low-priority uplink channels for transmission. Determine the high-priority uplink channels finally determined by the channel multiplexing process, the high-priority uplink channels finally determined by the PUCCH rewriting process, and the high-priority uplink channels that do not participate in the channel multiplexing and PUCCH rewriting among the high-priority uplink channels determined in Step 5 as the finally available high-priority uplink channels for transmission.

[0114] Optionally, another implementation manner of the above Steps 5 to 7 is:

[0115] Step 5: Perform the channel multiplexing process and the PUCCH rewriting process among the remaining high-priority uplink channels in Step 1 to obtain the high-priority uplink channels finally determined by the channel multiplexing process, the high-priority uplink channels finally determined by the PUCCH rewriting process, and the high-priority uplink channels that do not participate in the channel multiplexing and PUCCH rewriting processes.

[0116] Step 6: Cancel the uplink channels whose transmission resources in the low-priority uplink channels obtained in Step 4 and the transmission resources of the high-priority uplink channels obtained in Step 5 overlap in the time domain.

[0117] Step 7: Cancel the uplink channels whose transmission resources in the low-priority uplink channels obtained in Step 6 conflict with the semi-static downlink symbols and / or SSB symbols to obtain the finally available low-priority uplink channels for transmission. Cancel the uplink channels whose transmission resources conflict with the semi-static downlink symbols and / or SSB symbols among the high-priority uplink channels finally determined by the channel multiplexing process, the high-priority uplink channels finally determined by the PUCCH rewriting process, and the high-priority uplink channels that do not participate in the channel multiplexing and PUCCH rewriting determined in Step 5, and the remaining high-priority uplink channels are the finally available high-priority uplink channels for transmission.

[0118] In some feasible embodiments, for any one of the above-mentioned low-priority uplink channels and high-priority uplink channels, the conflict between the transmission resources of the uplink channel and the semi-static downlink symbols includes at least one of the following:

[0119] The time-domain symbols occupied by the transmission resources overlap with the semi-static downlink symbols;

[0120] The time interval between the start time of the first time-domain symbol occupied by the transmission resources and the end time of the last downlink symbol in the semi-static downlink symbols is less than the first threshold;

[0121] The time interval between the end time of the last time-domain symbol occupied by the transmission resources and the start time of the first downlink symbol in the semi-static downlink symbols is less than the second threshold.

[0122] Wherein, the specific values of the above-mentioned first threshold and the above-mentioned second threshold can be determined based on actual requirements and are not limited in this application.

[0123] In some feasible embodiments, for any one of the above-mentioned low-priority uplink channels and high-priority uplink channels, the conflict between the transmission resources of the uplink channel and the SSB symbols includes at least one of the following:

[0124] The time-domain symbols occupied by the transmission resources overlap with the SSB symbols;

[0125] The time interval between the start time of the first time-domain symbol occupied by the transmission resources and the end time of the last symbol in the SSB symbols is less than the third threshold;

[0126] The time interval between the end time of the last time-domain symbol occupied by the transmission resources and the start time of the first symbol in the SSB symbols is less than the fourth threshold.

[0127] Wherein, the specific values of the above-mentioned third threshold and the above-mentioned fourth threshold can be determined based on actual requirements and are not limited in this application.

[0128] As an example, see Figure 3 , Figure 3 is a schematic distribution diagram of an uplink channel provided by an embodiment of this application. As can be seen from Figure 3 , LP PUCCH-1 and LP-PUCCH-2 overlap in the time domain, and HP PUCCH-1, HP PUCCH-2 and HP PUSCH overlap in the time domain. Then, the steps for determining the final uplink channel used for communication based on the communication method provided by the embodiment of this application are as follows:

[0129] Step 1. Assume Figure 3If LP PUCCH-1 and LP-PUCCH-2 in the indicated time slot are not the uplink channels corresponding to the PUCCH rewriting process, then the first low-priority uplink channels are LP PUCCH-1 and LP-PUCCH-2.

[0130] Step 2: If the transmission resources of LP-PUCCH-2 conflict with the semi-static downlink symbols, then cancel LP-PUCCH-2 to obtain LP-PUCCH-1.

[0131] Step 3: Since there is no conflict between the remaining uplink channel (LP-PUCCH-1) and other low-priority uplink channels, there is no need to perform channel multiplexing of low-priority uplink channels at this time.

[0132] Step 4: Assume Figure 3 If HP PUCCH-1 and HP PUCCH-2 in the indicated time slot are not the uplink channels corresponding to the PUCCH rewriting process, then the first high-priority uplink channels are HP PUCCH-1, HP PUCCH-2, and HP PUSCH. Since the transmission resources of HP PUCCH-1, HP PUCCH-2, and HP PUSCH do not conflict with the semi-static downlink symbols, there is no need to cancel any of the uplink channels. Based on this step, HP PUCCH-1, HP PUCCH-2, and HP PUSCH can be obtained.

[0133] Step 5: Since there is no conflict between LP PUCCH-1 obtained in Step 3 and HP PUCCH-1, HP PUCCH-2, and HP PUSCH obtained in Step 4, there is no need to cancel LP PUCCH-1. Based on this step, LP PUCCH-1 can be obtained.

[0134] Step 6: Perform channel multiplexing on the high-priority uplink channels obtained in Step 4, that is, multiplex HP PUCCH-1 and HP PUCCH-2 to obtain HP PUCCH-3. Since the transmission resources of HP PUCCH-3 and HP PUSCH overlap in the time domain, it is necessary to multiplex the UCI carried by HP PUCCH-3 onto HP-PUSCH to obtain HP PUCCH-3 and HPPUSCH. Further cancel the uplink channels whose transmission resources in HP PUCCH-3 and HP PUSCH conflict with the semi-static downlink symbols or SSB symbols to obtain HP PUSCH.

[0135] Step 7: Since the transmission resources of LP PUCCH-1 obtained in Step 5 and HP PUSCH obtained in Step 6 do not overlap in the time domain, there is no need to cancel LP PUCCH-1. Based on this step, LP PUCCH-1 can be obtained.

[0136] Step 8: Since the LP PUCCH-1 obtained in Step 7 does not conflict with the semi-static downlink symbols, there is no need to cancel LP PUCCH-1. Thus, LP PUCCH-1 is determined as the final low-priority uplink channel available for transmission. For the transmission resources of the HP PUSCH (which carries the UCI of both HP PUCCH-1 and HP PUCCH-2) obtained in Step 6 that do not conflict with the semi-static downlink symbols or SSB symbols, HP PUSCH is determined as the final high-priority uplink channel available for transmission.

[0137] Step 9: Based on the HP PUSCH and LP PUCCH-1 finally available for transmission obtained in Step 8, communication is then carried out based on the HP PUSCH and LP PUCCH-1.

[0138] In this example, another implementation manner of Steps 6 to 9 is as follows:

[0139] Step 6: Perform channel multiplexing on the high-priority uplink channel obtained in Step 4, that is, multiplex HP PUCCH-1 and HP PUCCH-2 to obtain HP PUCCH-3. Since the transmission resources of HP PUCCH-3 and HP PUSCH overlap in the time domain, the UCI carried by HP PUCCH-3 needs to be multiplexed onto HP-PUSCH to obtain HP PUCCH-3 and HP PUSCH.

[0140] Step 7: Since the transmission resources of the LP PUCCH-1 obtained in Step 5 and the HP PUCCH-3 obtained in Step 6 overlap in the time domain, it is necessary to cancel LP PUCCH-1. Since all the low-priority uplink channels obtained in Step 5 are cancelled, no low-priority uplink channel is obtained in this step.

[0141] Step 8: For the transmission resources of the HP PUSCH (which carries the UCI of both HP PUCCH-1 and HP PUCCH-2) obtained in Step 6 that do not conflict with the semi-static downlink symbols or SSB symbols, HP PUSCH is determined as the final high-priority uplink channel available for transmission.

[0142] Step 9: Based on Step 8, the HP PUSCH finally available for transmission can be obtained, and then communication is carried out based on the HP PUSCH.

[0143] As an example, refer to Figure 4 , Figure 4 which is another distribution schematic diagram of the uplink channel provided by the embodiment of the present application. From Figure 4It can be known that, assuming that LP PUCCH-1 is covered by LP-PUCCH-2, that is, LP PUCCH-1 is the uplink channel corresponding to the PUCCH rewriting process, and LP-PUCCH-2 is the uplink channel finally determined by the PUCCH rewriting process. Assuming that HP PUCCH-1 is covered by HP-PUCCH-2, that is, HP PUCCH-1 is the uplink channel corresponding to the rewriting process, and HP-PUCCH-2 is the uplink channel finally determined by the PUCCH rewriting process.

[0144] Then, determining the uplink channel finally used for communication based on the communication method provided by the embodiments of the present application includes the following steps:

[0145] Step 1: Determine that the low-priority uplink channel finally determined by the PUCCH rewriting process in this time slot is LP PUCCH-2.

[0146] Step 2: Since the transmission resources of LP PUCCH-2 obtained in Step 1 do not conflict with semi-static downlink symbols, LP PUCCH-2 is not cancelled. Based on this step, LP PUCCH-2 can be obtained.

[0147] Step 3: Since there is no conflict between LP PUCCH-2 obtained in Step 2 and other low-priority uplink channels, channel multiplexing of low-priority uplink channels is not required at this time.

[0148] Step 4: Since HP PUCCH-1 and HP PUCCH-2 are high-priority uplink channels corresponding to the PUCCH rewriting process, no high-priority uplink channels are obtained based on this step.

[0149] Step 5: Since no high-priority uplink channels are obtained in Step 4, any low-priority uplink channels in Step 3 do not need to be cancelled. Based on this step, LP PUCCH-2 can be obtained.

[0150] Step 6: Cancel the uplink channels whose transmission resources conflict with semi-static downlink symbols or SSB symbols in HP PUCCH-1 and HP PUCCH-2 to obtain HP PUCCH-2.

[0151] Step 7: Since the transmission resources of LP PUCCH-2 obtained in Step 5 and HP PUCCH-2 obtained in Step 6 do not overlap in the time domain, LP PUCCH-2 does not need to be cancelled. Based on this step, LP PUCCH-2 is obtained.

[0152] Step 8: Since the transmission resources in the LP PUCCH-2 obtained in Step 7 and the HP PUCCH-2 obtained in Step 6 do not conflict with semi-static downlink symbols or SSB symbols, the LP PUCCH-2 and HP PUCCH-2 are determined as the final uplink channels available for transmission.

[0153] Step 9: Based on the LP PUCCH-2 and HP PUCCH-2 finally available for transmission obtained in Step 8, communication is then performed based on the LP PUCCH-2 and HP PUCCH-2.

[0154] In this example, another implementation of Steps 6 to 9 is as follows:

[0155] Step 6: Since the transmission resources of the HP PUCCH-1 and HP PUCCH-2 obtained in Step 4 do not conflict with semi-static downlink symbols or SSB symbols, the HP PUCCH-1 and HP PUCCH-2 are not cancelled. The HP PUCCH-1 and HP PUCCH-2 are obtained based on this step.

[0156] Step 7: Since the transmission resources of the LP PUCCH-2 obtained in all of Step 5 and the HP PUCCH-1 obtained in Step 6 overlap in the time domain, the LP PUCCH-2 needs to be cancelled. No low-priority uplink channels are obtained based on this step.

[0157] Step 8: Cancel the HP PUCCH-1 in which the transmission resources in the HP PUCCH-1 and HP PUCCH-2 obtained in Step 6 conflict with semi-static downlink symbols or SSB symbols, and obtain the HP PUCCH-2. Since no high-priority uplink channels are obtained in Step 7, the HP PUCCH-2 available for transmission can be obtained based on this step.

[0158] Step 9: Based on the HP PUCCH-2 finally available for transmission obtained in Step 8, communication is then performed based on the HP PUCCH-2.

[0159] Based on the communication method provided in the embodiments of the present application, when there are low-priority uplink channels and high-priority uplink channels in a time slot for a network device and a terminal device, and there are uplink channels in which the transmission resources conflict with semi-static downlink symbols and uplink channels in which the transmission resources overlap in the time domain among the uplink channels, a unified method can be used to determine the uplink channels for communication, which can improve the communication transmission performance and has high applicability.
