APPARATUS AND METHOD FOR REDUCING UPSTREAM CONTROL CHANNEL RESOURCES IN A COMMUNICATIONS SYSTEM

摘要

A system and method for allocating one or more Physical downlink Control Channel (PDCCH) resource and correspondingly allocating one or more Physical Uplink Control Channel (PUCCH) resource within the PUCCH. The allocation of the one or more PUCCH resource can be based on the allocation of one or more previously allocated PUCCH resources within the PUCCH that are associated with one or more other mobile devices. For example, the allocation of the current PDCCH resource and corresponding PUCCH resource can include determining the interference between the current PUCCH resource and the one or more other PUCCH resources having been previously allocated. Based on the interference, a corresponding PDCCH resource can be re-allocated so as to re-allocate the current PUCCH resource.

1. A communication device, comprising:
a transceiver configured to communicate via a communication path; and a controller communicatively coupled to the transceiver, and configured to:
analyze a first Physical Uplink Control Channel (PUCCH) resource that has been previously allocated to a first mobile device; andallocate a Physical Downlink Control Channel (PDCCH) resource to a second mobile device based on the analysis of the first PUCCH resource.
