Abstract
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.
Claims72
A method used in a wireless communications system that facilitates minimizing delay and random access load, comprising:
- accessing a system information block;
- identifying a number available random access resources based upon the accessed system information block;
- and
- utilizing at least one of the number of available random access resources.
A wireless communications apparatus, comprising:
- at least one processor configured to:
- access a system information block;
- identify a number available random access resources based upon the accessed system information block;
- utilize at least one of the number of available random access resources;
- and
- a memory coupled to the at least one processor.
A wireless communications apparatus that minimizes delay and random access load within a wireless environment, comprising:
- means for accessing a system information block;
- means for identifying a number available random access resources based upon the accessed system information block;
- and
