Timing offset indications for higher frequency bands
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, a physical downlink control channel (PDCCH) that includes a grant for a communication scheduled via the PDCCH prior to a radio resource control configuration indicating a timing offset between the PDCCH and the communication scheduled via the PDCCH. The UE and/or the network node may determine a timing offset between the PDCCH and the communication scheduled via the PDCCH based at least in part on a default time domain resource assignment table for a subcarrier spacing associated with the communication. Numerous other aspects are described.
1. A user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
receive, from a network node, a physical downlink control channel (PDCCH) that includes a grant for a communication scheduled via the PDCCH prior to a radio resource control (RRC) configuration indicating a timing offset between the PDCCH and the communication scheduled via the PDCCH, wherein:
the timing offset includes a k0 parameter based at least in part on the communication including a physical downlink shared channel, or
the timing offset includes a k2 parameter based at least in part on the communication including a physical uplink shared channel; and
determine a timing offset between the PDCCH and the communication scheduled via the PDCCH based at least in part on a default time domain resource assignment (TDRA) table for a subcarrier spacing associated with the communication, wherein the default TDRA table indicates a maximum value for the timing offset that is based at least in part on a default PDCCH monitoring periodicity defined for the subcarrier spacing associated with the communication.
2. The UE of claim 1 , wherein the timing offset is associated with a start and length indicator value that covers a whole slot based at least in part on the k0 parameter having a value greater than zero.
3. The UE of claim 1 , wherein the one or more processors are further configured to:
receive an RRC configuration that includes a table indicating a range of timing offset values between a subsequent PDCCH and a subsequent communication scheduled via the subsequent PDCCH, wherein the range of timing offset values indicated in the table is based at least in part on the subcarrier spacing.
4. The UE of claim 1 , wherein the subcarrier spacing is at least 480 kilohertz.
5. A network node for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
transmit, to a user equipment (UE), a physical downlink control channel (PDCCH) that includes a grant for a communication scheduled via the PDCCH prior to a radio resource control (RRC) configuration indicating a timing offset between the PDCCH and the communication scheduled via the PDCCH, wherein:
the timing offset includes a k0 parameter based at least in part on the communication including a physical downlink shared channel, or
the timing offset includes a k2 parameter based at least in part on the communication including a physical uplink shared channel; and
determine a timing offset between the PDCCH and the communication scheduled via the PDCCH based at least in part on a default time domain resource assignment (TDRA) table for a subcarrier spacing associated with the communication, wherein the default TDRA table indicates a maximum value for the timing offset that is based at least in part on a default PDCCH monitoring periodicity defined for the subcarrier spacing associated with the communication.
6. The network node of claim 5 , wherein the timing offset is associated with a start and length indicator value that covers a whole slot based at least in part on the k0 parameter having a value greater than zero.
7. The network node of claim 5 , wherein the one or more processors are further configured to:
transmit, to the UE, an RRC configuration that includes a table indicating a range of timing offset values between a subsequent PDCCH and a subsequent communication scheduled via the subsequent PDCCH, wherein the range of timing offset values indicated in the table is based at least in part on the subcarrier spacing.
8. The network node of claim 5 , wherein the subcarrier spacing is at least 480 kilohertz.
