Title:

RANDOM ACCESS CHANNEL DESIGN, METHODS, AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2018/082639

Kind Code:

A1

Abstract:

In response to receiving a random access channel message from a User Equipment (UE), a network element in a communication network may initiate a random access procedure, for example. The random access channel message includes multiple sequences, such as a first sequence associated with a group of UEs that includes the UE and a second sequence associated with the UE, and may be in any one of multiple different message formats. The random access procedure could include respective search stages for each of the multiple sequences. Power control for random access message transmission is also implemented by the UE in some embodiments.
