Abstract: A method for defining new control channels in a wireless communications network is described, the method comprising reserving, by a first wireless communications apparatus, a portion of wireless communication resources for general data communications according to a legacy network specification, allocating, by the first wireless communications apparatus, a subset of the reserved portion of wireless communication resources for communicating control data according to a non-legacy network specification, receiving, at the first wireless communications apparatus, legacy control data from a second wireless communications apparatus, and transmitting the legacy control data over the subset from the first wireless communications apparatus. Further, a corresponding apparatus and a computer-readable medium are described.

Abstract: Systems and methodologies are described that facilitate synchronizing timing among wireless nodes in a wireless communication network. A tracking wireless node can synchronize to a global positioning system (GPS) signal if available. Alternatively, the tracking wireless node can receive quality metrics related to one or more target nodes. The quality metrics can relate to parameters that can be utilized to evaluate the target node for timing synchronization. Based on the quality metrics, the tracking wireless node can select a target wireless node for timing synchronization. The tracking wireless node can subsequently synchronize timing with the target wireless node. In addition, the tracking wireless node can continually evaluate surrounding wireless nodes to detect whether other wireless nodes have higher quality metrics than the current target wireless nodes and can accordingly resynchronize with nodes having higher metrics.

Abstract: Techniques for managing interference in a wireless network are described. A base station may receive enhanced pilot measurement reports from user equipments (UEs) and may make an interference management decision based on the received reports. The base station may select a serving base station for a UE based on an enhanced pilot measurement report received from the UE. The base station may determine resources with a low target interference level at a neighbor base station and may avoid scheduling a UE for uplink transmission on the resources. The base station may also determine whether to reserve resources for a neighbor base station based on data performance of the neighbor base station, whether the neighbor base station observes high interference from UEs served by the base station, or whether UEs served by the neighbor base station observe high interference from the base station, which may be determined based on the enhanced pilot measurement reports.

Abstract: Techniques for selecting a serving base station for a terminal in a wireless communication network are described. In one design, multiple candidate base stations for the terminal may be identified, with each candidate base station being a candidate for selection as the serving base station for the terminal. The multiple candidate base stations may include base stations with different transmit power levels and/or may support interference mitigation. One of the multiple candidate base stations may be selected as the serving base station. In one design, the serving base station may be selected based on at least one metric for each candidate base station. The at least one metrics may be for pathloss, effective transmit power, effective geometry, projected data rate, control channel reliability, network utility, etc. The selected candidate base station may have a lower SINR than a highest SINR among the multiple candidate base stations.

Abstract: SYSTEMS AND METHODOLOGIES ARE DESCRIBED THAT FACILITATE SYNCHRONIZING TIMING AMONG WIRELESS NODES IN A WIRELESS COMMUNICATION NETWORK. A TRACKING WIRELESS NODE CAN SYNCHRONIZE TO A GLOBAL POSITIONING SYSTEM (GPS) SIGNAL IF AVAILABLE. ALTERNATIVELY, THE TRACKING WIRELESS NODE CAN RECEIVE QUALITY METRICS RELATED TO ONE OR MORE TARGET NODES. THE QUALITY METRICS CAN RELATE TO PARAMETERS THAT CAN BE UTILIZED TO EVALUATE THE TARGET NODE FOR TIMING SYNCHRONIZATION. BASED ON THE QUALITY METRICS, THE TRACKING WIRELESS NODE CAN SELECT A TARGET WIRELESS NODE FOR TIMING SYNCHRONIZATION. THE TRACKING WIRELESS NODE CAN SUBSEQUENTLY SYNCHRONIZE TIMING WITH THE TARGET WIRELESS NODE. IN ADDITION, THE TRACKING WIRELESS NODE CAN CONTINUALLY EVALUATE SURROUNDING WIRELESS NODES TO DETECT WHETHER OTHER WIRELESS NODES HAVE HIGHER QUALITY METRICS THAN THE CURRENT TARGET WIRELESS NODES AND CAN ACCORDINGLY RESYNCHRONIZE WITH NODES HAVING HIGHER METRICS.
