Multiplexing of physical sidelink control channel (pscch) and physical sidelink shared channel (pssch)

A transmit (Tx) user equipment (UE) operative to perform sidelink vehicle-to-everything (V2X) transmission, comprising:

• an antenna;
• a transceiver coupled to the antenna;
• one or more processors coupled to the transceiver;
• and
• memory coupled to the one or more processors, wherein the one or more processors are operative to:
• identify transmission parameters for communicating with a receive (Rx) UE;
• map the transmission parameters to time-and-frequency resources assigned to the Tx UE for the sidelink V2X communication;
• encode control information and data according to the transmission parameters;
• and
• transmit, via the transceiver and the antenna, encoded control information in a Physical Sidelink Control Channel (PSCCH) and encoded data in a Physical Sidelink Shared Channel (PSSCH) using a first portion and a second portion, respectively, of the time-and-frequency resources, wherein
• a first part of the PSSCH uses a first set of time resources overlapping with the PSCCH and a first set of frequency resources non-overlapping with the PSCCH, and
• a second part of the PSSCH uses a second set of time resources non-overlapping with the PSCCH and a second set of frequency resources overlapping with the PSCCH.

A receive (Rx) user equipment (UE) operative to receive sidelink vehicle-to-everything (V2X) transmission, comprising:

• an antenna;
• a transceiver coupled to the antenna;
• one or more processors coupled to the transceiver;
• and
• memory coupled to the one or more processors, wherein the one or more processors are operative to:
• decode received symbols for control information over one or more subchannels using blind detection;
• based on the control information, identify a first portion and a second portion of time-and-frequency resources used by a transmit (Tx) UE as a Physical Sidelink Control Channel (PSCCH) and a Physical Sidelink Shared Channel (PSSCH), respectively, for the sidelink V2X transmission;
• and
• decode data in the PSSCH according to the control information in the PSCCH, wherein
• a first part of the PSSCH uses a first set of time resources overlapping with the PSCCH and a first set of frequency resources non-overlapping with the PSCCH, and
• a second part of the PSSCH uses a second set of time resources non-overlapping with the PSCCH and a second set of frequency resources overlapping with the PSCCH.
