20120275327 | NETWORK-CENTRIC LINK ADAPTATION FOR COORDINATED MULTIPOINT DOWNLINK TRANSMISSION - A Coordinated MultiPoint (CoMP) cell controller performs network-centric link adaptation for User Equipment (UE) in the CoMP cell. The CoMP cell controller receives at least infrequent channel estimates from a UE in the CoMP cell, from which it estimates downlink channel and thermal noise at the UE. The CoMP cell controller is aware of the desired signal to be received at the UE, and the intra-CoMP cell interference to the UE caused by transmissions to other UEs in the CoMP cell. The CoMP cell receives from the UE reports of inter-CoMP cell interference caused by transmissions by other CoMP cells. Based on the downlink channel quality, the desired signal, the intra-CoMP cell interference, the inter-CoMP cell interference, and the thermal noise, the CoMP cell controller performs link adaptation by selecting modulation and coding schemes, and other transmission parameters, for an upcoming transmission duration (such as a TTI). | 2012-11-01 |

20120275421 | TECHNIQUES FOR ALIGNING APPLICATION OUTPUT AND UPLINK RESOURCE ALLOCATION IN WIRELESS COMMUNICATION SYSTEMS - A technique for reducing a time delay between an application output at a subscriber station and uplink resource allocation for the subscriber station includes scheduling, between periodic uplink resource allocations, one or more probe uplink resource allocations for the subscriber station. Next, respective information in at least one of the one or more probe uplink resource allocations is received at an access point. Finally, subsequent periodic uplink resource allocations are scheduled based on at least one of the one or more probe uplink resource allocations. | 2012-11-01 |

A method of operating a Base Station (BS) includes configuring a bitmap to indicate whether radio resources are allocated to respective Access Terminals (ATs) according to resource scheduling, generating a resource allocation message including the configured bitmap and at least one of bit allocation information of the bitmap and bit deallocation information of the bitmap, and transmitting the resource allocation message. | 2012-11-01 |
20120275423 | DISTRIBUTED CHANNEL ASSIGNMENT - Disclosed, in example embodiment herein, is an apparatus comprising an interface and channel selection logic coupled to the interface. The channel selection logic is operable to receive data representative of neighboring wireless devices to a wireless device occupying a channel for a plurality of channels via the interface. The channel selection logic is responsive to receiving the data representative of neighboring wireless devices occupying the plurality of channels to generate a graph for each of the plurality of channels, wherein vertices of the graph represent the wireless device and neighboring wireless devices occupying the channel and edges of the graph represent wireless devices with overlapping coverage areas. The channel selection logic selects the channel for the wireless device whose graph has the smallest radius. | 2012-11-01 |
