Abstract
A system and method for random access configurations are disclosed herein. In one embodiment, a method performed by a communication device includes: defining, based on a parameter for communication with a communication node, at least one of: a plurality of random access channel (RACH) groups, and a relationship between individual RACH groups of the plurality of RACH groups and measurement results; obtaining the measurement results from a plurality of signals; determining a matching RACH group from the plurality of RACH groups based on the measurement results; and sending a message using at least one resource of the matching RACH group.

A method performed by a communication device, the method comprising:
- determining, based on at least one parameter for communication with a communication node:
- a plurality of random access channel (RACH) groups, and
- a relationship between an individual RACH group of the plurality of RACH groups and a plurality of signals, wherein each individual RACH group of the plurality of RACH groups comprises at least one RACH occasion and a number of contention-based RACH preambles per synchronization signal (SS) block, and the at least one parameter indicates the number of contention-based RACH preambles in each individual RACH group and a number of RACH groups per RACH occasion, wherein each RACH occasion corresponds to a time instance in which a contention-based RACH preamble may be transmitted and wherein the plurality of RACH groups are determined based on a RACH group period;
- obtaining measurement results from the plurality of signals, wherein the plurality of signals comprises at least one SS block;
- determining a matching RACH group from the plurality of RACH groups based on the measurement results;
- and
- sending a message using at least one resource of the matching RACH group to the communication node.
