摘要： In an OFDM communication system, wherein a frequency bandwidth is divided into multiple Physical Resource Units (PRUs), a Frequency Partitioning Configuration Module (FPCM) is provided that configures a physical layer for use in multiple coverage areas. The FPCM divides the PRUs into a first group, for frequency selective allocations, and a second group, for frequency diverse allocations. The FPCM subdivides each of the two groups into multiple sets of PRUs, maps the sets of PRUs from the first group to consecutive PRUs allocated for contiguous segment allocation (CS-PRUs), and maps the sets of PRUs from the second group to consecutive PRUs allocated for distributed segment allocation (DS-PRUs). The FPCM permutes the DS-PRUs and allocates the CS-PRUs and the permuted DS-PRUs to at least one frequency partition.

摘要： During operation, the choice of the initial ranging code (sometimes referred to as a ranging preamble code, or a random-access preamble) at the mobile station is associated with a PMI feedback to be signaled to the base station during the initial ranging. More particularly, during initial system access a ranging code is transmitted by the mobile station to the base station. The mobile station chooses one of the available ranging codes based on the channel conditions and associates the ranging code with channel feedback information. The ranging code is then transmitted to the base station, and provides the base station with the channel feedback information.

摘要： A determination of link quality (CSR) is made from the subscriber station to a relay station. A determination of link quality (CRB) is made from the relay station to the base station, and a determination of link quality (CSB) is made from the subscriber station to the base station. A quality of a first link path from the subscriber station to the base station that passes through the relay station is determined based on at least the link qualities (Csr, Crb). A quality of a second link path from the subscriber station to the base station that does not pass through the relay station is determined based on at least the link quality (Csb). Finally, a determination is made whether to utilize the first link path or the second link path from the subscriber station to the base station based on at least the quality of the first and second link paths.

摘要： A mobile station (110) selects an initial data rate for communication between base station (107) and mobile station (110). Mobile station (110) communicates the selected initial data rate to base station (107) through uplink (112). Base station (107) determines a difference level of interference condition experienced by mobile station (107) between a time when the initial data rate was selected by mobile station (110) and a time when base station (107) prepares to communicate to mobile station (110). Base station (107) selects a final data rate for transmission from base station (107) to mobile station (110) based on the determined difference level of interference condition. As such, the initial data rate may be modified to the final data rate while maximizing the down link capacity.

摘要： Remote units (113) having large amounts of data to transmit will be dynamically assigned Orthogonal Variable Spreading Factor (OVSF) codes corresponding to higher data rates and remote units (113) with lower amounts of data to be transmitted will be assigned OVSF codes corresponding to lower data rates. Additionally, in an alternate embodiment of the present invention, once system interference becomes greater than a predetermined threshold, the data rate between the base station (100) and remote units (113) in communication with the base station (100) is reduced. The reduction of the data rate between the base station (100) and remote units (113) occurs by changing the current OVSF codes utilized by both the remote units (113) and the base station (100).
摘要翻译：具有大量要发送的数据的远程单元（113）将被动态地分配对应于较高数据速率的正交可变扩频因子（OVSF）代码和具有较低数据量的远程单元（113）将被分配对应于较低的数据速率。另外，在本发明的替代实施例中，一旦系统干扰变得大于预定阈值，则与基站（100）通信的基站（100）和远程单元（113）之间的数据速率减小。基站（100）和远程单元（113）之间的数据速率的降低通过改变由远程单元（113）和基站（100）所使用的当前OVSF代码而发生。
