Abstract
Wireless communications may be used to support transmission power control. A reference signal may be mapped to a power control parameter set. A message to schedule a transmission may be received that indicates the power control parameter set. A transmission power for the scheduled transmission may be determined based on the reference signal.
Claims24
A method comprising:
- based on a received medium access control (MAC) control element (CE) indicating a reference signal, mapping, by a wireless device, the reference signal to a power control parameter set;
- receiving downlink control information (DCI) for scheduling transmission of an uplink signal, wherein the DCI comprises a sounding reference signal resource indicator (SRI) field indicating the power control parameter set;
- and
- transmitting, based on the reference signal, the uplink signal.
1 more element
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- based on a received medium access control (MAC) control element (CE) indicating a reference signal, map the reference signal to a power control parameter set;
- receive downlink control information (DCI) for scheduling transmission of an uplink signal, wherein the DCI comprises a sounding reference signal resource indicator (SRI) field indicating the power control parameter set;
- and
- transmit, based on the reference signal, the uplink signal.
4 more elements
A non-transitory computer-readable medium storing instructions that, when executed, cause a wireless device to:
- based on a received medium access control (MAC) control element (CE) indicating a reference signal, map the reference signal to a power control parameter set;
- receive downlink control information (DCI) for scheduling transmission of an uplink signal, wherein the DCI comprises a sounding reference signal resource indicator (SRI) field indicating the power control parameter set;
- and
- transmit, based on the reference signal, the uplink signal.
