RANDOM ACCESS FOR LOW LATENCY WIRELESS COMMUNICATIONS

摘要

Wireless devices may exchange data related to multiple available random access procedures for network access. A random access procedure of the available random access procedures may be selected, and a random access message transmitted based on the selected random access procedure. Available random access procedures may include procedures that provide for a different number of random access messages or that are for use in communications having different transmission time intervals (TTIs). For example, a random access procedure may include a total of two random access messages or a total of four random access messages for accessing the wireless communications network. The use of one random access procedure instead of the other may depend on a wireless device's location relative to its serving base station.
