Abstract
A method for transmitting uplink control information (UCI) is provided. The method includes determining, by a user equipment (UE), the physical uplink control channel (PUCCH) resource for transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information and scheduling request (SR) information, and determining, by the UE, an occupied PUCCH resource and transmitting the HARQ-ACK and SR according to the SR resource and whether it is necessary to transmit the SR currently.
Claims18
A method for transmitting uplink control information (UCI), the method comprising:
- determining, by a user equipment (UE), physical uplink control channel (PUCCH) resources for transmitting at least one selected from hybrid automatic repeat request acknowledgement (HARQ-ACK) information and scheduling request (SR) information, wherein one of the PUCCH resources are used as an SR resource;
- determining, by the UE, an occupied PUCCH resource;
- determining, by the UE, whether it is necessary to transmit the SR information currently;
- and
- transmitting the HARQ-ACK information and the SR information according to the SR resource.
A method for setting uplink time advance (TA), the method comprising:
- for one user equipment (UE), configuring the TA as NTA+=NTA,prop++NTA,offset+, wherein, NTA,prop+ is the necessary TA to align an uplink slot and a downlink slot, and NTA,offset+ is an additional TA;
- and
- for another UE, configuring the TA as NTA−=NTA,prop−−NTA,offset−,
- wherein, NTA,prop− is the necessary TA to align an uplink slot and a downlink slot, and NTA,offset− is a decreased TA, and
- wherein, the sum of NTA,prop+ and NTA,offset− is equal to an integer multiple of the slot length.
A user equipment (UE) comprising:
- a transceiver;
- at least one memory configured to store instructions;
- and
- at least one processor configured to perform the stored instructions to:
- determine physical uplink control channel (PUCCH) resources for transmitting at least one selected from hybrid automatic repeat request acknowledgement (HARQ-ACK) information and scheduling request (SR) information, wherein one of the PUCCH resources are used as an SR resource,
- determine the occupied PUCCH resource,
- determine whether it is necessary to transmit the SR information currently, and
- transmit the HARQ-ACK information and the SR information according to the SR resource.
