Abstract
Certain aspects of the present disclosure provide techniques for a multi-user data packet, such as a physical downlink shared channel (PDSCH) packet. A method by a base station (BS) includes sending a control channel, such as physical downlink control channel (PDCCH), scheduling a plurality of user equipment (UEs) for a data packet transmission and sending data for the plurality of UEs in a single transport block on the scheduled data packet. The UE receives the control channel and data packet, and determines the data in the multi-user data packet that is intended for the UE.
Claims29
A method for wireless communications by a user equipment (UE), comprising:
- receiving a downlink grant on a physical downlink control channel (PDCCH), wherein the downlink grant schedules a physical downlink shared channel (PDSCH) transmission for a plurality of UEs;
- receiving the PDSCH transmission, wherein the PDSCH transmission includes a single transport block with data for the plurality of UEs;
- determining at least a portion of the data in the PDSCH transmission that is intended for the UE;
- sending a negative acknowledgement (NACK) for a previous PDSCH transmission;
- and
- monitoring for the PDCCH based on sending the NACK.
An apparatus for wireless communications, comprising:
- means for receiving a downlink grant on a physical downlink control channel (PDCCH), wherein the downlink grant schedules a physical downlink shared channel (PDSCH) transmission for a plurality of apparatuses;
- means for receiving the PDSCH transmission, wherein the PDSCH transmission includes a single transport block with data for the plurality of apparatuses;
- means for determining at least a portion of the data in the PDSCH transmission that is intended for the apparatus;
- sending a negative acknowledgement (NACK) for a previous PDSCH transmission;
- and
- monitoring for the PDCCH based on sending the NACK.
An apparatus for wireless communications, comprising:
- a receiver configured to:
- receiving a downlink grant on a physical downlink control channel (PDCCH), wherein the downlink grant schedules a physical downlink shared channel (PDSCH) transmission for a plurality of apparatuses;
- receiving the PDSCH transmission, wherein the PDSCH transmission includes a single transport block with data for the plurality of apparatuses;
- at least one processor coupled with a memory and configured to determine at least a portion of the data in the PDSCH transmission that is intended for the apparatus;
- sending a negative acknowledgement (NACK) for a previous PDSCH transmission;
- and
- monitoring for the PDCCH based on sending the NACK.
A non-transitory computer readable medium having computer executable code stored thereon for wireless communications by user equipment (UE), comprising:
- code for receiving a downlink grant on a physical downlink control channel (PDCCH), wherein the downlink grant schedules a physical downlink shared channel (PDSCH) transmission for a plurality of UEs;
- coded for receiving the PDSCH transmission, wherein the PDSCH transmission includes a single transport block with data for the plurality of UEs;
- code for determining at least a portion of the data in the PDSCH transmission that is intended for the UE;
- code for sending a negative acknowledgement (NACK) for a previous PDSCH transmission;
- and
- code for monitoring for the PDCCH based on sending the NACK.
