Abstract
In an aspect, a UE may determine an initial transmission power for transmission of a physical random access channel (PRACH) preamble of a PRACH procedure based upon a final PRACH preamble transmission power associated with a set of historical completed PRACH procedures. The UE may further attempt an initial transmission of the PRACH preamble based on the determined initial transmission power.
Claims30
A method of operating a user equipment (UE), comprising:
- determining an initial transmission power for transmission of a physical random access channel (PRACH) preamble of a PRACH procedure based upon a final PRACH preamble transmission power associated with a set of historical completed PRACH procedures;
- and
- attempting an initial transmission of the PRACH preamble based on the determined initial transmission power.
A user equipment (UE), comprising:
- means for determining an initial transmission power for transmission of a physical random access channel (PRACH) preamble of a PRACH procedure based upon a final PRACH preamble transmission power associated with a set of historical completed PRACH procedures;
- and
- means for attempting an initial transmission of the PRACH preamble based on the determined initial transmission power.
A user equipment (UE), comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- determine an initial transmission power for transmission of a physical random access channel (PRACH) preamble of a PRACH procedure based upon a final PRACH preamble transmission power associated with a set of historical completed PRACH procedures;
- and
- attempt an initial transmission of the PRACH preamble based on the determined initial transmission power.
A non-transitory computer-readable medium containing instructions stored thereon, for causing at least one processor in a user equipment (UE) to:
- determine an initial transmission power for transmission of a physical random access channel (PRACH) preamble of a PRACH procedure based upon a final PRACH preamble transmission power associated with a set of historical completed PRACH procedures;
- and
- attempt an initial transmission of the PRACH preamble based on the determined initial transmission power.
