Abstract
A transmission parameter configuration method includes a first device that determines a transmission parameter used for group communication, and sends information including the transmission parameter to a second device in a group through a broadcast message, where the first device is a management device of the group, and the transmission parameter includes a frequency domain resource or a demodulation reference signal (DMRS) pattern that is used for group communication of the group.
Claims18
A transmission parameter configuration method implemented by a first device, wherein the transmission parameter configuration method comprises:
- determining a transmission parameter for a first group communication, wherein the first device is a management device of a group, and wherein the transmission parameter comprises a demodulation reference signal (DMRS) pattern that is for a second group communication of the group;
- sending information comprising the transmission parameter to a second device in the group through a broadcast message, wherein the broadcast message is a master information block-sidelink (MIB-SL) message transmitted on a physical sidelink broadcast channel (PSBCH) or a sidelink control information (SCI) message transmitted on a physical sidelink control channel (PSCCH);
- and
- performing one of:
- add a field indicating the DMRS pattern to the transmission parameter in the MIB-SL message when the broadcast message is the MIB-SL message transmitted on the PSBCH;
- or
- send the information to the second device in the group on the resource through the SCI message when the broadcast message is the SCI message transmitted on the (PSCCH), wherein the SCI message comprises a field indicating the DMRS pattern.
A first device comprising:
- a memory configured to store a program;
- and
- a processor coupled to the memory, wherein the program causes the processor to be configured to:
- determining a transmission parameter for a first group communication, wherein the first device is a management device of a group, and wherein the transmission parameter comprises a demodulation reference signal (DMRS) pattern that is for a second group communication of the group;
- sending information comprising the transmission parameter to a second device in the group through a broadcast message, wherein the broadcast message is a master information block-sidelink (MIB-SL) message transmitted on a physical sidelink broadcast channel (PSBCH) or a sidelink control information (SCI) message transmitted on a physical sidelink control channel (PSCCH);
- and
- performing one of:
- add a field indicating the DMRS pattern to the transmission parameter in the MIB-SL message when the broadcast message is a master information block-sidelink (MIB-SL) message transmitted on a physical sidelink broadcast channel (PSBCH);
- or
- send the information to the second device in the group on the resource through the SCI message when the broadcast message is a sidelink control information (SCI) message transmitted on a physical sidelink control channel (PSCCH), wherein the SCI message comprises a field indicating the DMRS pattern.
A computer program product comprising computer- executable instructions for storage on a non-transitory computer-readable medium that, when executed by a processor, cause an apparatus to:
- determine a transmission parameter for a first group communication, wherein the apparatus is a management device of a group, and wherein the transmission parameter comprises a demodulation reference signal (DMRS) pattern that is for a second group communication of the group;
- and
- send information comprising the transmission parameter to a second device in the group through a broadcast message, wherein the broadcast message is a master information block-sidelink (MIB-SL) message transmitted on a physical sidelink broadcast channel (PSBCH) or a sidelink control information (SCI) message transmitted on a physical sidelink control channel (PSCCH);
- and
- perform one of:
- add a field indicating the DMRS pattern to the transmission parameter in the MIB-SL message when the broadcast message is a master information block- sidelink (MIB-SL) message transmitted on a physical sidelink broadcast channel (PSBCH);
- or
- send the information to the second device in the group on the resource through the SCI message when the broadcast message is a sidelink control information (SCI) message transmitted on a physical sidelink control channel (PSCCH).
