Abstract
A method for performing wireless communication by a first device and a device for supporting same are provided. The method may include receiving a plurality of reference signals from a second device through a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH), herein, the plurality of reference signals are transmitted through a plurality of antenna ports, determining a reference signal received power (RSRP) value using the plurality of reference signals based on indexes for the plurality of antenna ports, and transmitting the RSRP value to the second device.
Claims15
A method for performing, by a first device, wireless communication, the method comprising:
- receiving sidelink control information (SCI) carried on a physical sidelink control channel (PSCCH) used for scheduling of a physical sidelink shared channel (PSSCH);
- receiving demodulation reference signals (DMRSs) associated with a physical sidelink shared channel (PSSCH);
- measuring PSSCH reference signal received power (RSRP) over DMRS resource elements for the PSSCH according to the SCI,
- wherein the PSSCH RSRP is a linear average over power contributions of the DMRS resource elements of antenna ports that carry the DMRSs associated with the PSSCH summed over the antenna ports.
A first device for performing wireless communication, the first device comprising:
- one or more memories storing instructions;
- one or more transceivers;
- and
- one or more processors connected to the one or more memories and the one or more transceivers,
- wherein the one or more processors execute the instructions to:
- receive sidelink control information (SCI) carried on a physical sidelink control channel (PSCCH) used for scheduling of a physical sidelink shared channel (PSSCH);
- receive demodulation reference signals (DMRSs) associated with a physical sidelink shared channel (PSSCH);
- measure PSSCH reference signal received power (RSRP) over DMRS resource elements for the PSSCH according to the SCI,
- wherein the PSSCH RSRP is a linear average over power contributions of the DMRS resource elements of antenna ports that carry the DMRSs associated with the PSSCH summed over the antenna ports.
A device configured to control a first user equipment (UE), the device comprising:
- one or more processors;
- and
- one or more memories being operably connectable to the one or more processors and storing instructions,
- wherein the one or more processors execute the instructions to:
- receive sidelink control information (SCI) carried on a physical sidelink control channel (PSCCH) used for scheduling of a physical sidelink shared channel (PSSCH);
- receive demodulation reference signals (DMRSs) associated with a physical sidelink shared channel (PSSCH);
- measure PSSCH reference signal received power (RSRP) over DMRS resource elements for the PSSCH according to the SCI,
- wherein the PSSCH RSRP is a linear average over power contributions of the DMRS resource elements of antenna ports that carry the DMRSs associated with the PSSCH summed over the antenna ports.
