Methods and apparatus related to resource allocation in a wireless communications system

Abstract

Methods and apparatus of efficient communication of resource allocation are described. A base station transmits a resource assignment message, e.g., a state transition message, to a wireless terminal including a first part, e.g., a base station assigned wireless terminal On state identifier, identifying a resource being assigned and a second part, e.g., an ON state mask, identifying a portion of the resource allocated to the wireless terminal. The same resource allocation message information also communicates one of a plurality of different modes of commanded On state operation. The resource allocation message structure supports flexible allocation of available resources facilitating a resource to be partitioned differently at different times accommodating current needs. A predetermined recurring channel structure and association of segments with particular mask bits, facilitates allocated control segments to be used unambiguously without the need to include an overhead wireless terminal identifier field with the control report bits being communicated.

Description

technical field [0001] In general, the present invention relates to multi-user communication systems, and in particular, the present invention relates to methods and devices related to resource allocation in wireless communication systems. Background technique [0002] As wireless communication systems proliferate and the provision of multiple types of data communication services grows, the demand for the limited available air link resources (eg, spectrum) allocated to a particular base station for its cell continues to grow. Furthermore, the number of users and user demand for resources can vary over time and with events that can cause desired and undesired spikes in demand. The large number of users active simultaneously in a cell poses a challenge to meet user needs for timely transmission of uplink and / or Downlink user data. Resources (eg, allocations) used for control signaling purposes reduce the amount of resources available for transmission of user data. Complicat...

Problems solved by technology

Another approach involves reserving a fixed amount of control channel resources for each wireless terminal that will be simultaneously operating in the on state; however, when different wireless terminal types have different resource requirements and / or the same wireless terminal has This approach will not be efficient enough for different resource requirements (e.g. due to different channel conditions, applications used, power availability, etc.)
