Abstract
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive RACH configuration information on a downlink carrier of a first set of carriers, wherein the RACH configuration information pertains to the first set of carriers and to a second set of carriers; and selectively perform a RACH procedure with regard to the first set of carriers or the second set of carriers based at least in part on the RACH configuration information. Numerous other aspects are provided.
Claims40
A method of wireless communication performed by a user equipment, comprising:
- receiving random access channel (RACH) configuration information,
- wherein the RACH configuration information includes:
- a threshold associated with a first set of carriers and a second set of carriers,
- wherein the first set of carriers includes an uplink carrier that is a primary uplink carrier, and
- wherein the second set of carriers includes an uplink carrier that is a supplementary uplink carrier;
- and
- selectively performing a RACH procedure with regard to the first set of carriers or the second set of carriers based at least in part on the RACH configuration information.
A user equipment (UE) for wireless communication, comprising:
- memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- receive random access channel (RACH) configuration information,
- wherein the RACH configuration information includes:
- a threshold associated with a first set of carriers and a second set of carriers,
- wherein the first set of carriers includes an uplink carrier that is a primary uplink carrier, and
- wherein the second set of carriers includes an uplink carrier that is a supplementary uplink carrier;
- and
- selectively perform a RACH procedure with regard to the first set of carriers or the second set of carriers based at least in part on the RACH configuration information.
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
- receive random access channel (RACH) configuration information,
- wherein the RACH configuration information includes:
- a threshold associated with a first set of carriers and a second set of carriers,
- wherein the first set of carriers includes an uplink carrier that is a primary uplink carrier, and
- wherein the second set of carriers includes an uplink carrier that is a supplementary uplink carrier;
- and
- selectively perform a RACH procedure with regard to the first set of carriers or the second set of carriers based at least in part on the RACH configuration information.
An apparatus for wireless communication, comprising:
- means for receiving random access channel (RACH) configuration information,
- wherein the RACH configuration information includes:
- a threshold associated with a first set of carriers and a second set of carriers,
- wherein the first set of carriers includes an uplink carrier that is a primary uplink carrier, and
- wherein the second set of carriers includes an uplink carrier that is a supplementary uplink carrier;
- and
- means for selectively performing a RACH procedure with regard to the first set of carriers or the second set of carriers based at least in part on the RACH configuration information.
