Abstract
Certain aspects of the present disclosure provide techniques for indicating an overlap of downlink transmissions with one or more random access channel occasions (ROs). A method that may be performed by a user equipment (UE) includes receiving signaling from a base station (BS) including an indication of whether one or more ROs will overlap with downlink transmissions in one or more periods of time, transmitting, to the BS based on the indication, a random access channel (RACH) preamble in an RO of the one or more ROs during the one or more periods of time, and performing a RACH procedure with the BS based on the transmitted RACH preamble.
Claims29
A method of wireless communication by a user equipment (UE), comprising:
- receiving signaling from a base station (BS) including an indication of whether one or more random access channel occasions (ROs) will overlap with downlink transmissions in one or more periods of time;
- transmitting, to the BS based on the indication, a random access channel (RACH) preamble in an RO of the one or more ROs during the one or more periods of time, wherein:
- the RO of the one or more ROs comprises a full-duplex RO when the RO overlaps with the downlink transmissions;
- and
- the RO comprises a half-duplex RO when the RO does not overlap with the downlink transmissions;
- and
- performing a RACH procedure with the BS based on the transmitted RACH preamble.
A method of wireless communication by a base station (BS), comprising:
- transmitting signaling to a user equipment (UE) including an indication of whether one or more random access channel occasions (ROs) will overlap with downlink transmissions in one or more periods of time;
- receiving, from the UE based on the indication, a random access channel (RACH) preamble in an RO of the one or more ROs during the one or more periods of time, wherein:
- the RO of the one or more ROs comprises a full-duplex RO when the RO overlaps with the downlink transmissions;
- and
- the RO comprises a half-duplex RO when the RO does not overlap with the downlink transmissions;
- and
- performing a RACH procedure with the UE based on the received RACH preamble.
An apparatus for wireless communication by a user equipment (UE), comprising:
- a memory comprising executable instructions;
- and
- a processor configured to execute the executable instructions and cause the apparatus to:
- receive signaling from a base station (BS) including an indication of whether one or more random access channel occasions (ROs) will overlap with downlink transmissions in one or more periods of time;
- transmit, to the BS based on the indication, a random access channel (RACH) preamble in an RO of the one or more ROs during the one or more periods of time, wherein:
- the RO of the one or more ROs comprises a full-duplex RO when the RO overlaps with the downlink transmissions;
- and
- the RO comprises a half-duplex RO when the RO does not overlap with the downlink transmissions;
- and
- perform a RACH procedure with the BS based on the transmitted RACH preamble.
