Abstract
A first wireless device receives, from a base station, one or more radio resource control messages indicating a type of demodulation reference signal (DMRS). The first wireless device determines a length of the DMRS. The first wireless device determines a DMRS configuration of a physical sidelink shared channel (PSSCH) based on based on the type and the length of the DMRS. The first wireless device transmits, to a second wireless device, sidelink control information comprising the DMRS configuration of the PSSCH.
Claims20
A method comprising:
- receiving, by a first wireless device from a base station, one or more radio resource control (RRC) messages indicating a type of demodulation reference signal (DMRS);
- determining a length of the DMRS;
- determining a DMRS configuration of a physical sidelink shared channel (PSSCH) based on the type and the length of the DMRS;
- and
- transmitting, to a second wireless device, sidelink control information (SCI) comprising the DMRS configuration of the PSSCH.
2 more elements
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:
- receive one or more radio resource control (RRC) messages indicating a type of demodulation reference signal (DMRS);
- determine a length of the DMRS;
- determine a DMRS configuration of a physical sidelink shared channel (PSSCH) based on the type and the length of the DMRS;
- and
- transmit, to a second wireless device, sidelink control information (SCI) comprising the DMRS configuration of the PSSCH.
5 more elements
A system comprising:
- a base station comprising:
- one or more first processors;
- and
- first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:
- transmit one or more radio resource control (RRC) messages indicating a type of demodulation reference signal (DMRS);
- and
- a wireless device comprising:
- one or more second processors;
- and
- second memory storing instructions that, when executed by the one or more second processors, cause the wireless device to:
- receive the one or more RRC messages;
- determine a length of DMRS;
- determine a DMRS configuration of a physical sidelink shared channel (PSSCH) based on the type and the length of DMRS;
- and
- transmit, to the second wireless device, sidelink control information (SCI) comprising the DMRS configuration of the PSSCH.
