| 20080232492 | METHOD AND APPARATUS FOR PROVIDING CHANNEL QUALITY AND PRECODING METRIC FEEDBACK IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATION SYSTEM - An Orthogonal Frequency Division Multiplexing communication system, wherein a frequency bandwidth is divided into one or more Resource Blocks Groups (RBGs) each having one or more Resource Blocks, provides for feedback of channel quality information and precoding metrics for a same at least one RBG of the one or more RBGs. More particularly, a user equipment measures one or more channel quality parameters associated with at least one RBG of the one or more RBGs, determines channel quality information and a precoding metric for an RBG of the at least one RBG, and reports the channel quality information and a precoding metric determined for the RBG to a radio access network. In one embodiment of the invention, the RBG whose channel quality information and precoding metric are reported may be selected from the at least one RBG based on the measured channel quality parameters. | 09-25-2008 |
| 20090067377 | MEDIUM ACCESS CONTROL FRAME STRUCTURE IN WIRELESS COMMUNICATION SYSTEM - A wireless communication infrastructure entity configured to allocate radio resources, in a radio frame, to a wireless terminal compliant with a first protocol and to a wireless terminal compliant with a second protocol. The radio frame including a first protocol resource region and a second protocol resource region. The radio frame including a first protocol allocation control message that allocates resources within the first protocol resource region to the wireless terminal compliant with the first protocol, and a second protocol allocation control message that allocates resources within the second protocol resource region to the wireless terminal compliant with the second protocol. | 03-12-2009 |
| 20090111445 | METHOD AND APPARATUS FOR CONTROLLING UPLINK TRANSMISSION TIMING IN A COMMUNICATION NETWORK - A method and corresponding system for controlling uplink timing in a communication network ( | 04-30-2009 |
| 20090147735 | SYSTEM AND METHOD FOR NON-STANDARD WIRELESS BANDWIDTH COMMUNICATIONS - A wireless communications method and device including a transmitter ( | 06-11-2009 |
| 20090154605 | SYSTEM AND METHOD FOR PERFORMING DIRECT MAXIMUM LIKELIHOOD DETECTION - A method, wireless device, and wireless communication system perform Maximum Likelihood Detection. At least one data signal is accepting on at least one communication channel ( | 06-18-2009 |
| 20100165951 | System and Method for Downlink Signaling for High Speed Uplink Packet Access - A wireless communication system ( | 07-01-2010 |
| 20110190018 | METHOD AND APPARATUS FOR PROVIDING A DISTRIBUTED ARCHTECTURE DIGITAL WIRELESS COMMUNCIATION SYSTEM - A communication system supports H-ARQ, AMC, active set handoff, and scheduling functions in a distributed fashion by allowing a mobile station (MS) to signal control information corresponding to an enhanced reverse link transmission to Active Set base transceiver stations (BTSs) and by allowing the BTSs to perform control functions that were supported by an RNC in the prior art. The communication system allows time and SIR-based H-ARQ flush functions at the BTSs during soft handoff (SHO), provides an efficient control channel structure to support scheduling, H-ARQ, AMC functions for an enhanced reverse link, or uplink, channel in order to maximize throughput, and enables an MS in a SHO region to choose a scheduling assignment corresponding to a best TFRI out of multiple assignments it receives from multiple active set BTS. As a result, the enhanced uplink channel can be scheduled during SHO without any explicit communication between the BTSs. | 08-04-2011 |
| 20110310837 | METHOD AND APPARATUS FOR REDUCING ROUND TRIP LATENCY AND OVERHEAD WITHIN A COMMUNICATION SYSTEM - During operation radio frames are divided into a plurality of subframes. Data is transmitted over the radio frames within a plurality of subframes, and having a frame duration selected from two or more possible frame durations. | 12-22-2011 |
