Abstract

A method for a user equipment (UE) includes decoding an information element (IE) MAC-CellGroupConfig, determining that a field lch-BasedPrioritization of the IE MAC-CellGroupConfig is not configured, determining that a plurality of configured grants (CGs) overlap in time domain, each of the plurality of CGs indicative of uplink resources for allocation to a corresponding one of a plurality of CG physical uplink share channels (CG-PUSCH), causing uplink control information (UCI) to be multiplexed onto a CG-PUSCH, and selecting the CG-PUSCH with multiplexed UCI for transmission.

Claims (28)

1. A method for a user equipment (UE), comprising:

decoding an information element (IE) MAC-CellGroupConfig;

determining that a field Ich-BasedPrioritization of the IE MAC-CellGroupConfig is not configured;

determining that a plurality of configured grants (CGs) overlap in time domain, each of the plurality of CGs indicative of uplink resources for allocation to a corresponding one of a plurality of CG physical uplink share channels (CG-PUSCHs);

causing uplink control information (UCI) to be multiplexed onto a CG-PUSCH; and

selecting the CG-PUSCH with multiplexed UCI for transmission over other CG-PUSCHs without the multiplexed UCI that correspond to CGs that overlap in the time domain without the multiplexed UCI, wherein the CG-PUSCH is selected over the other CG-PUSCHs based on the presence of the multiplexed UCI.

2. The method of claim 1 , wherein the selecting comprises:

selecting, from the plurality of CGs, a CG indicative of uplink resources for allocation to the CG-PUSCH with multiplexed UCI; and

creating a medium access control (MAC) protocol data unit (PDU) for the CG-PUSCH with multiplexed UCI.

3. The method of claim 2 , further comprising:

in accordance with a determination that the CG indicative of uplink resources for allocation to the CG-PUSCH with multiplexed UCI has been selected, not creating a MAC PDU for a different CG-PUSCH than the CG-PUSCH with multiplexed UCI.

4. The method of claim 1 , further comprising:

determining that there is logical channel (LCH) data available for one of the plurality of CG-PUSCHs,

wherein the causing the UCI to be multiplexed comprises:

causing the UCI to be multiplexed onto the CG-PUSCH for which the LCH data is available.

5. The method of claim 1 , further comprising:

causing the selected CG-PUSCH with multiplexed UCI to be transmitted.

6. The method of claim 1 , wherein the IE MAC-CellGroupConfig is derived from a message received from a network, the message selected from a group consisting of an RRCSetup message and an RRCReconfiguration message.

7. The method of claim 1 , wherein the UCI comprises at least one selected from a group consisting of a hybrid automatic repeat request acknowledgement/non-acknowledgement (HARQ ACK/NACK), channel state information (CSI), a channel quality indicator (CQI), a precoding matrix indicator (PMI), and a rank indication (RI).

8. A method for a user equipment (UE), comprising:

decoding an information element (IE) MAC-CellGroupConfig;

determining that a field Ich-BasedPrioritization of the IE MAC-CellGroupConfig is not configured;

determining that a plurality of configured grants (CGs) overlap in time domain; and

causing uplink control information (UCI) to be multiplexed onto a physical uplink control channel (PUCCH) and not onto a physical uplink share channel (PUSCH) in response to determining that the plurality of CGs overlap in the time domain.

9. The method of claim 8 , further comprising:

causing the PUCCH with multiplexed UCI to be transmitted.

10. The method of claim 8 , wherein the IE MAC-CellGroupConfig is derived from a message received from a network, the message selected from a group consisting of an RRCSetup message and an RRCReconfiguration message.

11. The method of claim 8 , wherein the UCI comprises at least one selected from a group consisting of a scheduling request (SR), a hybrid automatic repeat request acknowledgement/non-acknowledgement (HARQ ACK/NACK), channel state information (CSI), a channel quality indicator (CQI), a precoding matrix indicator (PMI), and a rank indication (RI).
