Abstract
Certain aspects of the present disclosure provide techniques for wireless communication. A method that may be performed by a base station (BS), the method including determining a plurality of root sets, wherein each root set of the plurality of root sets comprise at least a first root and a second root. In some examples, the method includes transmitting signaling that indicates the plurality of root sets.
Claims20
An apparatus method of wireless communication at a network entity, comprising:
- determining a plurality of root sets, wherein:
- determining the plurality of root sets comprises determining a respective root set for each beam of a plurality of beams based on one or more respective parameters associated with the beam;
- and
- each root set of the plurality of root sets comprise at least a first root and a second root;
- transmitting signaling that indicates the plurality of root sets;
- and
- receiving, from a user equipment (UE), a physical random access channel (PRACH) that comprises a preamble sequence, the preamble sequence based at least in part on a first root set of the plurality of root sets.
4 more elements
A network entity, comprising:
- one or more processors individually or collectively configured to execute instructions stored on one or more memories and to cause the network entity to:
- determine a plurality of root sets, wherein:
- in order to determine the plurality of root sets, the one or more processors are configured to cause the network entity to determine a respective root set for each beam of a plurality of beams based on one or more respective parameters associated with the beam;
- and
- each root set of the plurality of root sets comprise at least a first root and a second root;
- transmit signaling that indicates the plurality of root sets;
- and
- receive, from a user equipment (UE), a physical random access channel (PRACH) that comprises a preamble sequence, the preamble sequence based at least in part on a first root set of the plurality of root sets.
