Alternatively, the network device configures a DRX on-off pattern (on-off mode) or DTX on-off pattern for one or more carriers of the terminal by configuration signaling. The periodic DTX on-off pattern includes parameters such as time domain period, time domain offset, on duration, or off duration. The DRX on-off pattern of the cycle includes parameters such as a time domain cycle, a time domain offset, an on duration, or an off duration.

Taking DTX as an example, referring to fig. 1b, the period start position of DTX is the start position of on duration. Referring to fig. 1c, the cycle start position of dtx is the start position of the off duration.

In some embodiments, if the terminal has multiple serving carriers, the multiple carriers may be configured with cell DTX/DRX configurations, respectively. After the base station configures cell DTX/DRX for one or more carriers of the terminal, the base station activates cell DTX/DRX using the multicast DCI, and only after being activated, the cell DTX/DRX mechanism on the carrier starts to operate.

In some embodiments, the multiplexed information is carried in the second channel, or the multiplexed information is carried in the third channel, or the multiplexed information is carried in other channels than the second channel and the third channel.

In some embodiments, multiplexing the information carried by the at least one second channel and the information carried by the at least one third channel may also be understood as channel multiplexing the at least one second channel and the at least one third channel.

In some embodiments, the multiplexed channel is one of the at least one second channel, or the multiplexed channel is one of the at least one third channel, or the multiplexed channel is other than the second channel and the third channel.

For example, for the case that the channel carrying the feedback information of the dynamically scheduled PDSCH overlaps with the CSI-PUCCH in the time domain, assuming that the channel carrying the feedback information of the dynamically scheduled PDSCH and the CSI-PUCCH are both in the cell DRX inactivity period, the channel carrying the feedback information of the dynamically scheduled PDSCH corresponds to the second channel and the CSI-PUCCH corresponds to the third channel. CSI information in CSI-PUCCH may be carried on a channel of feedback information of dynamically scheduled PDSCH. In this case, the first channel refers to a second channel (a channel carrying feedback information of the dynamically scheduled PDSCH). The CSI-PUCCH refers to a PUCCH carrying CSI reports.

In some embodiments, the cell DRX inactivity period may also be referred to as a cell DRX inactivity period, a cell DRX inactivity duration, a cell DRX inactivity time, etc., which embodiments of the present disclosure do not limit.

In some embodiments, the at least one third channel is transmitted during a cell DRX inactivity period and the at least one second channel is not transmitted during the cell DRX inactivity period.

In some embodiments, the at least one second channel may not be transmitted during the cell DRX inactivity period or may be made such that the at least one second channel cannot be transmitted during the cell DRX inactivity period.

However, the information carried in the at least one second channel needs to be transmitted, and the at least one third channel and the at least one second channel overlap in time domain, the information of the at least one third channel and the at least one second channel may be multiplexed.

In the embodiment of the present disclosure, there is a case where the second channel is not transmitted, and when information carried by at least one channel of the plurality of channels is carried on the first channel, adjustment needs to be performed on the information carried by the second channel.

In some embodiments, the second channel comprises a channel for transmitting SRs, and when information carried by at least one of the plurality of channels is carried on the first channel, bits corresponding to the SRs are considered to be 0. Alternatively, it is also understood that SR is considered as 0.

Alternatively, the bit corresponding to SR being regarded as 0 means that SR corresponds to a bit, the number of bits is 1 bit, and the bit is set to 0. Alternatively, it is also understood that the bit corresponding to SR is set to 0.

In the embodiment of the disclosure, if the second channel is not transmitted during the cell DRX inactive period, then the bit corresponding to the SR is considered to be 0 when the pair carries information on the first channel.

Optionally, when information carried by at least one channel of the plurality of channels is carried by the first channel, a bit corresponding to the SR is 0. Optionally, when information carried by at least one channel of the plurality of channels is carried on the first channel, the bit corresponding to the SR is regarded as negative.

In some embodiments, the second channel comprises a channel for transmitting SRs, and bits corresponding to the SRs are deemed to be absent when information carried by at least one of the plurality of channels is carried on the first channel.

In some embodiments, the second channel may be a channel carrying feedback information.

In some embodiments, the feedback information proposed by the embodiments of the present disclosure is HARQ-ACK information, or HARQ-NACK information, or other information, which is not limited by the embodiments of the present disclosure.

In some embodiments, the second channel carries feedback information corresponding to SPS PDSCH in an inactive period of cell DTX, the bits corresponding to the feedback information being considered as preset bit values.

Alternatively, the bit corresponding to the feedback information is regarded as a preset bit value, which may also be understood as the bit corresponding to the feedback information is set to a preset bit value.

In some embodiments, the preset bit value is set by the terminal, or by the network device, or by a communication protocol convention, and embodiments of the present disclosure are not limited. For example, the preset bit value is 1 bit, which is for example 1, or 0. Or the preset bit value may also be 2 bits, 3 bits or other values.

In some embodiments, the second channel carries feedback information corresponding to the SPS PDSCH, the feedback information configures a feedback manner based on the CBG of the code block group, the SPS PDSCH is located in an inactive period of the cell DTX, bits corresponding to the feedback information are regarded as preset bit values, and the number of the feedback information is the same as the number of the CBG groups.

In some embodiments, the second channel carries a PUCCH for transmitting a CSI report, and when information carried by at least one of the plurality of channels is carried on the first channel, the bit corresponding to the CSI report is deemed to be absent.

It should be noted that, in the embodiments of the present disclosure, the information carried by at least one channel of the plurality of channels is carried by the terminal in the first channel as an example. In another embodiment, if each of the plurality of channels is not transmitted during the cell DRX inactivity period, the information carried in the plurality of channels does not need to be carried in the first channel.

Step S2104: the first channel is not transmitted during the DRX inactivity period, and the terminal discards the first channel.

In some embodiments, the plurality of channels includes a second channel and a third channel. Wherein the second channel is not transmitted during the cell DRX inactivity period. The third channel is transmitted during the cell DRX inactivity period.

In some embodiments, the first channel is the same as the third channel, or the first channel is the same as the second channel, or the first channel is different from the third channel, or the first channel is different from the second channel, or the first channel is different from the third channel and the second channel.

In some embodiments, the terminal discarding the first channel includes discarding the first channel and information carried by the first channel. In some embodiments, the terminal discarding the first channel includes discarding the first channel and all information carried by the first channel.

In some embodiments, the first channel is CG-PUSCH or PUCCH carrying feedback information of dynamically scheduled PDSCH.

In some embodiments, for example, in a case where a channel carrying feedback information of a dynamically scheduled PDSCH overlaps with a CG-PUSCH in a time domain, assuming that the channel carrying feedback information of the dynamically scheduled PDSCH and the CG-PUSCH are both within a cell DRX inactivity period, the channel carrying feedback information of the dynamically scheduled PDSCH corresponds to a third channel and the CG-PUSCH corresponds to a second channel. Feedback information of the dynamically scheduled PDSCH may be multiplexed onto the CG-PUSCH, so in this case, the first channel is the same as the second channel, which is the CG-PUSCH.

It should be noted that the network device determines that the first channel is not transmitted during the DRX inactivity period, and the first channel is discarded.

In some embodiments, the steps 203-205 may be understood as setting the information of the second channel to be preset content, then carrying the information carried by at least one of the channels in the first channel, and then determining whether to discard the channel in which the multiplexed information is located. Alternatively, it may be understood as determining whether to discard the multiplexed information.

The above-described scheme will be described below by way of example.

For example, the third channel is a PUCCH where HARQ-ACK corresponding to dynamically scheduled PDSCH is located, the second channel 1 is CG-PUSCH, and the second channel 2 is a PUCCH where SR is located. In case the third channel has time domain overlap with the second channel 1 and the second channel 2 to be multiplexed, then the SR is regarded as carrying bit 0 and is carried in the second channel 1 (CG-PUSCH) together with the HARQ-ACK carried in the third channel. Since the second channel 1 (CG-PUSCH) is not transmitted during the cell DRX inactivity period, the CG-PUSCH will be discarded, not transmitting the CG-PUSCH, with the multiplexed HARQ-ACKs and SRs on the CG-PUSCH discarded together.

For another example, the third channel 1 is a PUCCH where HARQ-ACK corresponding to the dynamically scheduled PDSCH is located, the third channel 2 is a PUCCH where SR is located, the second channel 1 is CG-PUSCH, and the second channel 2 is a PUCCH where CSI report is located. In case that the third channel 1, the third channel 2 and the second channel 1 and the second channel 2 have time domain overlapping to be multiplexed, the CSI report is set to 1111, and the HARQ-ACK carried by the third channel 1, the SR carried by the third channel 2, and the CSI report carried by the second channel 2 are carried together in the second channel 1 (CG-PUSCH). Since the second channel 1 (CG-PUSCH) is not transmitted during the cell DRX inactivity period, the CG-PUSCH will be discarded, not transmitting the CG-PUSCH, with the multiplexed HARQ-ACK, SR, CSI report on the CG-PUSCH discarded.

It should be noted that, in the embodiment of the present disclosure, information of a plurality of channels is directly carried on a first channel, and then the first channel is discarded for illustration. In another embodiment, other processes may be performed without performing the steps 203-205, and the other processes are described below.

In some embodiments, the second channel is discarded and information carried by at least one of the channels other than the second channel in the plurality of channels is carried on the first channel. In the embodiment of the present disclosure, the manner of carrying the information on at least one channel of the channels except the second channel is similar to the above embodiment, and will not be described herein. It should be noted that, in the above embodiment, the second channel is discarded first, and then the information carried by at least one of the remaining channels is carried by the first channel.

In some embodiments, dropping the second channels refers to dropping all of the second channels. Alternatively, it is also understood that all second channels are discarded as well as the information carried on the second channels.

In some embodiments, the second channel comprises at least one of:

a channel for transmitting an SR during a cell DRX inactivity period;

CG-PUSCH in cell DRX inactive periods;

The embodiments of the present disclosure are illustrated below.

For example, the third channel is a PUCCH where HARQ-ACK corresponding to dynamically scheduled PDSCH is located, the second channel 1 is CG-PUSCH, and the second channel 2 is a channel where SR is located. In the case where the third channel has time domain overlapping with the second channel 1 and the second channel 2 to be multiplexed, the second channel 1 and the second channel 2 are discarded first, and only the third channel remains. The third channel will be transmitted at this time.

For another example, the third channel 1 is a PUCCH where HARQ-ACK corresponding to the dynamically scheduled PDSCH is located, the third channel 2 is a dynamically scheduled PUSCH channel, the second channel 1 is a CG-PUSCH, and the second channel 2 is a channel where SR is located. In the case that the third channel 1, the third channel 2, the second channel 1 and the second channel 2 have time domain overlapping to be multiplexed, the second channel 1 and the second channel 2 are discarded first, and only the third channel 1 and the third channel 2 remain. The HARQ-ACK in the third channel 1 will be transmitted on the third channel 2 at this time and the third channel 2 will be transmitted.

Note that SR corresponds to priority. And if the second channel comprises a channel used for transmitting the SR in the cell DRX non-active period, discarding the second channel carrying other SR except the first priority in the cell DRX non-active period when discarding the second channel, and reserving the second channel carrying the SR with higher priority than the first priority.

In some embodiments, the second channel comprises CG-PUSCH. The CG-PUSCH is discarded first and at least part of the information carried by the at least one third channel and the information carried by the second channel other than the CG-PUSCH is carried on the first channel. It should be noted that, in the above embodiment, a portion of the second channel is discarded, and then the information carried by the second channel that is not discarded and the information carried by the remaining third channel are carried on the first channel.

In some embodiments, the second channel, other than CG-PUSCH, comprises at least one of:

a channel for transmitting an SR during a DRX inactive period;

The embodiments of the present disclosure are illustrated below.

For example, the third channel is a PUCCH where HARQ-ACK corresponding to dynamically scheduled PDSCH is located, the second channel 1 is CG-PUSCH, and the second channel 2 is a channel where SR is located. When the third channel overlaps with the second channel 1 and the second channel 2 in time domain, the second channel 1 is discarded first, and only the third channel and the second channel 2 remain, and the HARQ-ACK and the SR are carried on the third channel, so that the third channel is transmitted at this time.

For another example, the third channel 1 is a PUCCH where HARQ-ACK corresponding to the dynamically scheduled PDSCH is located, the third channel 2 is a dynamically scheduled PUSCH channel, the second channel 1 is a CG-PUSCH, and the second channel 2 is a channel where SR is located. In the case that the third channel 1, the third channel 2, the second channel 1 and the second channel 2 have time domain overlapping to be multiplexed, the second channel 1 is discarded first, and only the third channel 1, the third channel 2 and the second channel 2 remain. Therefore, the HARQ-ACK in the third channel 1 and the SR in the second channel 2 are transmitted to the third channel 2, and the multiplexed third channel 2 is transmitted.

In view of the foregoing, the present disclosure may be understood as providing three schemes for determining the order of multiplexing information and discarding channels.

First kind: and setting the information of the second channel as preset content, multiplexing the information carried by at least one channel in the plurality of channels to the first channel, and determining whether to discard the first channel. Alternatively, it may be understood as determining whether to discard the multiplexed information.

Second kind: the second channel is discarded first, and then the information carried by the rest channels is multiplexed to the first channel.

Third kind: a part of the second channels are discarded, and information carried by the rest channels is multiplexed to the first channels.

According to the three processing schemes provided by the disclosure, when channels conflict in the time domain, the scheme of multiplexing information borne by a plurality of channels is adopted, so that the sequence of channel discarding and channel multiplexing is determined in the DRX non-activated period, the results after multi-channel multiplexing are consistent and uniquely determined for the terminal and the base station, and the reliability of communication is further ensured.

Step S2105: the first channel is not transmitted during the DRX inactivity period, and the first channel is not received.

In the embodiment of the present disclosure, step S2105 is taken as an example for explanation. In yet another embodiment, steps S2104-S2105 may not be performed, but the terminal may instead transmit the first channel. The network device receives a first channel.

Fig. 6 is a flow chart illustrating a communication method according to an embodiment of the present disclosure, and as shown in fig. 6, the embodiment of the present disclosure relates to a communication method, which includes:

in step S6101, the terminal performs UCI multiplexing.

Step S6102: the terminal discards channels that are not transmitted because they are affected by cell DTX/cell DRX.

(1) For SRs that are not transmitted due to being located in cell DRX non-active period, sr=0 can be considered.

(2) For SPS PDSCH that is not transmitted because it is located in cell DTX non-active period, its corresponding HARQ-ACK may be considered to be=1 bit NACK; or if the UE is configured with the HARQ-ACK feedback mode of the CBG and the group number of the CBG is M, the corresponding HARQ-ACK=Mbit NACK is considered; alternatively, the HARQ-ACK information may be directly considered to be absent.

(3) For a CSI-PUCCH channel that is not transmitted due to cell DTX/cell DRX non-active period effects, the CSI-PUCCH information may be considered to be a known bit sequence (e.g., a full 1bit sequence) of a set bit amount; alternatively, the CSI information may be directly considered to be absent.

Discarding channels that are affected by cell DTX/cell DRX but not transmitted at step 2 refers to discarding CG-PUSCH within cell DRX non-active period. If UCI is taken on the discarded CG-PUSCH, UCI is discarded along with CG-PUSCH.

In some embodiments, dropping is affected by cell DTX/cell DRX without transmitting SR/HARQ-ACK because SR HARQ-ACK is not well dropped because it is already encoded together with UCI information on other carriers in UCI multiplexing.

It should be noted that the embodiments of the present disclosure are described by taking steps 601-602 as an example. In yet another embodiment, the first and second embodiments,

step 1: those channels/information that are not transmitted because of the influence of cell DTX/cell DRX are discarded first.

step 2: and then performs UCI multiplexing.

In step 1 dropping the channel, the SR/CG-PUSCH in the cell DRX non-active period is dropped. The HARQ-ACK corresponding to SPS PDSCH in cell DTX non-active period is discarded.

Discarding of SRs may further take priority into account, e.g., discarding only low priority SRs, retaining high priority (if high priority SRs can be sent during cell DRX non-active duration, then the high priority SR channel should be retained)

Still alternatively, the method may comprise,

step 1: and discarding the CG-PUSCH in the cell DRX non-active period.

Step 2: UCI multiplexing is performed

Since only CG-PUSCH is discarded in step1, there may be HARQ-ACKs corresponding to SR in cell DRX non-active period and SPS PDSCH in cell DTX non-active period. These channels need to be taken into account in UCI multiplexing.
