Abstract:
In an OFDM communication system (100), wherein a frequency bandwidth is divided into multiple Physical Resource Units (PRUs), a Frequency Partitioning Configuration Module (FPCM) (118) is provided that configures a physical layer for use in multiple coverage areas. The FPCM divides (504) the PRUs into a first group, for frequency selective allocations, and a second group, for frequency diverse allocations. The FPCM subdivides (506) each of the two groups into multiple sets of PRUs, maps (510) the sets of PRUs from the first group to consecutive PRUs allocated for contiguous segment allocation (CS-PRUs), and maps (512) the sets of PRUs from the second group to consecutive PRUs allocated for distributed segment allocation (DS-PRUs). The FPCM permutes (514) the DS-PRUs and allocates (518) the CS-PRUs and the permuted DS-PRUs to at least one frequency partition.
Abstract:
A method and apparatus (300) for performing H-ARQ transmission is described herein. Bits received on a first transmission are stored (301) and combined with die bits received on later transmissions (304) thereby increasing the likelihood of a correct decoding on later transmissions (304). Additionally, a plurality of coding schemes (eg., Convolution Codes, Block Turbo Codes, Convolution Turbo Codes, Low Density Parity Check Codes,..., etc.) are utilized, with an information element being reserved to signal what form of H-ARQ is being utilized.
Abstract:
The present invention provides a method for enabling transparent relaying of data in order to improve the performance of a cellular system. Particularly, relaying on the uplink is performed by fixed entities called Transparent Relays (TR). The base station may allocate one or more TRs to relay the data transmissions associated with a particular CID (e.g., a particular subscriber station) on the uplink.
Abstract:
A base station (101) will request the transmission of quality information from a particular remote stations (102, 103) only when data is queued to be transmitted to the remote stations. Once a remote station begins the transmission of channel quality information, the transmission of such information continues until the data transmission is successfully delivered to the remote station. The base station receives the channel quality information and adjusts the modulation and coding of the remote stations accordingly. Where data is transmitted simultaneously to a plurality of remote stations, a set of queues (303) for the multiple remote stations is maintained, and based on queue status, a channel quality request messages is sent to a sub-set of remote stations with data queued.
Abstract:
A method for communicating control channel information in a wireless communication system, including transmitting a super- frame having a time-frequency resource region containing an allocation control channel and multiple pilot elements, at least some of which are associated with the allocation control channel, and indicating, in a configuration information control channel of the super-frame, a characteristic of the pilots elements associated with the allocation control channel.
Abstract:
A method in a wireless communication network (100) wherein information is communicated in a frame structure wherein each frame includes multiple sub-frames, including grouping at least two wireless communication terminals in a group, assigning the group to less than all sub-frames constituting a communication frame, and assigning a radio resource assignment control channel of one or more assigned sub-frames to the group. The control channel is used to assign radio resources to one or more terminals of the group.

Abstract:
A downlink frame (401) is divided in to similar sized resource blocks (403, 405, 407) with each co-channel sector scheduled to transmit from the beginning of its respective assigned resource block. Transmissions to remote units within the particular sector will occur only within the particular resource block, up to a point where all N resource units have been utilized. Beyond that point, additional transmissions are scheduled to be transmitted at the end of the resource blocks assigned to the other sectors.

Abstract:
A user device's (UD) radio link with a network node is determined to satisfy an entering condition for a measurement event, where there is a specified duration such as a TTT over which the entering condition shall be satisfied. A timer associated with that determination is initiated to track the specified duration, but prior to expiry of the tracked duration the UD experiences radio link blockage with the network node. Various options are presented for what measurements can be used to satisfy the requirements of the measuring event, the end result being the UD is able to wirelessly send a measurement report about the network node that satisfies the measurement event, hi various embodiments the timer is stopped and re-started, or it is suspended and resumed, and some embodiments use estimated measurements that are extrapolated and/or interpolated from actual measurements taken before and/or after the link blockage occurs.
