Physical random access channel resource selection

摘要

Systems and methodologies are described that facilitates managing assignment of available random access resources in order to minimize delay and random access load. A number of available random access resources can be defined by a network or a base station, wherein a user equipment can access the number of available random access resources via an information block. The user equipment can be randomly assigned or uniformly assigned to at least one of the number of available random access resources. Additionally, the network can adjust the defined number of available random access resources based upon reported delay, base station load, or historic load data for a base station.

1. A method used in a wireless communications system, comprising:
accessing a system information block comprising information regarding available random access resources for a base station available to any mobile device in a plurality of mobile devices; utilizing at least one of available random access resources; and implementing a time shift between a first Physical Random Access Channel (PRACH) configuration and a second Physical Random Access Channel (PRACH) configuration, wherein the first Physical Random Access Channel (PRACH) configuration relates to a mobile device in the plurality of mobile devices and the second PRACH configuration relates to a disparate mobile device in the plurality of mobile devices.
