Abstract
A method, system and apparatus for dynamic indication of physical uplink shared channel (PUSCH) transmission to a single transmission/reception point (TRP) or multiple TRPs are disclosed. According to one aspect, a method in a network node includes configure the WD with a first sounding reference signal, SRS, resource set, and with a second SRS resource set for physical uplink shared channel, PUSCH, and schedule, by sending a downlink control information, DCI, to the WD, a PUSCH transmission by the WD in at least one PUSCH transmission occasion associated with one of the first SRS resource set, the second SRS resource set, and both the first and the second SRS resource sets.
Claims14
A network node configured to communicate with a wireless device, WD, the network node comprising processing circuitry configured to:
- transmit to the WD a transmission and reception point, TRP, indicator, TRPI, field, the TRPI field indicating one or both of a first TRP and a second TRP to which a physical uplink shared channel, PUSCH, is to be transmitted, the TRPI field indicating which of a plurality of sounding reference signals, SRS, of an SRS resource set is enabled for the indicated one or both TRPs, the TRPI field indicating at least three codepoints, a first codepoint indicating a first SRS resource set, a second codepoint indicating a second SRS resource set, and a third codepoint indicating both the first and the second SRS resource sets;
- and
- schedule, by sending a downlink control information, DCI, to the WD, a PUSCH transmission by the WD in at least one PUSCH transmission occasion associated with the one or both of the first TRP and the second TRP.
A method implemented in a network node configured to communicate with a wireless device, WD, the method comprising:
- transmitting to the WD a transmission and reception point, TRP, indicator, TRPI, field, the TRPI field indicating one or both of a first TRP and a second TRP to which a physical uplink shared channel, PUSCH, is to be transmitted, the TRPI field indicating which of a plurality of sounding reference signals, SRS, of an SRS resource set is enabled for the indicated one or both TRPs, the TRPI field indicating at least three codepoints, a first codepoint indicating a first SRS resource set, a second codepoint indicating a second SRS resource set, and a third codepoint indicating both the first and the second SRS resource sets;
- and
- scheduling, by sending a downlink control information, DCI, to the WD, a PUSCH transmission by the WD in at least one PUSCH transmission occasions associated with the one or both of the first TRP and the second TRP.
A wireless device, WD, configured to communicate with one or more network nodes, the WD comprising a radio interface configured to:
- receive from one of the one or more network nodes a configuration of a transmission and reception point, TRP, indicator, TRPI, field, the TRPI field indicating one or both of a first TRP and a second TRP to which a Physical Uplink Shared Channel, PUSCH, transmission is to be transmitted, the TRPI field indicating which of a plurality of sounding reference signals, SRS, of an SRS resource set is enabled for the indicated one or both TRPs, the TRPI field indicating at least three codepoints, a first codepoint indicating a first SRS resource set, a second codepoint indicating a second SRS resource set, and a third codepoint indicating both the first and the second SRS resource sets;
- receive a downlink control information, DCI, configured to schedule a PUSCH transmission in at least one PUSCH transmission occasion,
- transmit the scheduled PUSCH transmission to the indicated one or both of the first TRP and the second TRP during the at least one PUSCH transmission occasion.
A method in a wireless device, WD, configured to communicate with one or more network nodes, the method comprising:
- receiving from one of the one or more network nodes a configuration of a transmission and reception point, TRP, indicator, TRPI, field, the TRPI field indicating one or both of a first TRP and a second TRP to which a Physical Uplink Shared Channel, PUSCH, transmission is to be transmitted, the TRPI field indicating which of a plurality of sounding reference signals, SRS, of an SRS resource set is enabled for the indicated one or both TRPs, the TRPI field indicating at least three codepoints, a first codepoint indicating a first SRS resource set, a second codepoint indicating a second SRS resource set, and a third codepoint indicating both the first and the second SRS resource sets;
- receiving a downlink control information, DCI, configured to schedule a PUSCH transmission in at least one PUSCH transmission occasion;
- and
- transmitting the scheduled PUSCH transmission to the indicated one or both of the first TRP and the second TRP during the at least one PUSCH transmission occasion.
