Abstract
Method and apparatus for using different beams for PDCCH and PDSCH. The apparatus receives a PDCCH transmission using a first receive beam, the PDCCH transmission scheduling a PDSCH transmission. The apparatus receives the PDSCH transmission using a second receive beam. The apparatus may select the second receive beam for the PDSCH transmission separately from the first receive beam for the PDCCH transmission. The apparatus may switch from the first receive beam to the second receive beam after reception of the PDCCH transmission to receive the PDSCH transmission.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the apparatus to:
- receive a physical downlink control channel (PDCCH) transmission using a first receive beam, the PDCCH transmission scheduling a physical downlink shared channel (PDSCH) transmission;
- and
- receive the PDSCH transmission using a second receive beam.
A method of wireless communication at a user equipment (UE), comprising:
- receiving a physical downlink control channel (PDCCH) transmission using a first receive beam, the PDCCH transmission scheduling a physical downlink shared channel (PDSCH) transmission;
- and
- receiving the PDSCH transmission using a second receive beam.
An apparatus for wireless communication at a user equipment (UE), comprising:
- means for receiving a physical downlink control channel (PDCCH) transmission using a first receive beam, the PDCCH transmission scheduling a physical downlink shared channel (PDSCH) transmission;
- and
- means for receiving the PDSCH transmission using a second receive beam.
A computer-readable medium storing computer executable code at a user equipment (UE), the code when executed by at least one processor causes the at least one processor to:
- receive a physical downlink control channel (PDCCH) transmission using a first receive beam, the PDCCH transmission scheduling a physical downlink shared channel (PDSCH) transmission;
- and
- receive the PDSCH transmission using a second receive beam.
