Abstract
Methods, a base unit and a remote unit are disclosed. A method comprises determining two or more SRS resource sets for codebook or non-codebook based UL transmission of the mobile unit in the condition that the number of antenna ports simultaneously used by the mobile unit for transmitting is smaller than the number of antenna ports simultaneously used by the mobile unit for receiving; and transmitting a trigger associated with the two or more SRS resource sets to the mobile unit to trigger SRS resource transmissions by the mobile unit.
Claims12
A base station, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the base station to:
- transmit a configuration comprising information to configure at least two sounding reference signal (SRS) resource sets for a user equipment (UE) for a codebook based transmission or a non-codebook based transmission;
- and
- transmit a first SRS resource indicator and a second SRS resource indicator to the UE for a physical uplink shared channel (PUSCH) transmission, wherein each of the first SRS resource indicator and the second SRS resource indicator indicates an SRS resource within one of the at least two SRS resource sets.
A user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive a configuration comprising information to configure at least two sounding reference signal (SRS) resource sets for the UE for a codebook based transmission or a non-codebook based transmission;
- and
- receive a first SRS resource indicator and a second SRS resource indicator from a base unit for a physical uplink shared channel (PUSCH) transmission, wherein each of the first SRS resource indicator and the second SRS resource indicator indicates an SRS resource within one of the at least two SRS resource sets.
A processor for wireless communication, comprising:
- at least one controller coupled with at least one memory and configured to cause the processor to:
- receive a configuration comprising information to configure at least two sounding reference signal (SRS) resource sets for the processor for a codebook based transmission or a non-codebook based transmission;
- and
- receive a first SRS resource indicator and a second SRS resource indicator from a base unit for a physical uplink shared channel (PUSCH) transmission, wherein each of the first SRS resource indicator and the second SRS resource indicator indicates an SRS resource within one of the at least two SRS resource sets.
A method performed by a user equipment (UE), the method comprising:
- receiving a configuration comprising information to configure at least two sounding reference signal (SRS) resource sets for the UE for a codebook based transmission or a non-codebook based transmission;
- and
- receiving a first SRS resource indicator and a second SRS resource indicator from a base unit for a physical uplink shared channel (PUSCH) transmission, wherein each of the first SRS resource indicator and the second SRS resource indicator indicates an SRS resource within one of the at least two SRS resource sets.
