摘要： A method and apparatus for performing spatial-division multiple access within a communication system is provided herein. During operation, nodes will return null subspace information along with their channel subspace information. The null subspace is similar to the channel subspace except that the null subspace information directs a base station to the matrix in a predefined codebook that results in minimum power being received at the node. The null subspace for each node is taken into consideration when communicating with a particular node.

摘要： A method (300, 400, 500, 600) of communicating with a subscriber station (102). Responsive to determining that a supplemental communication link with the subscriber station is desirable, at least a second access point (106, 108, 110, 112, 114, 116) can be identified to establish the supplemental communication link with the subscriber station. Information can be communicated to the second access point. The information can identify the subscriber station and a pilot zone in which downlink supplemental data is to be transmitted from the second access point to the subscriber station. Downlink supplemental data (150) also can be communicated to the second access point. The downlink supplemental data can improve integrity of data transmitted from a first access point (104) to the subscriber station when the downlink supplemental data is transmitted to the subscriber station from the second access point.

摘要： A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.

摘要： Multiple transmit antenna transmission together with preferably pseudo-random, antenna-specific, scrambling (PRAS) is utilized to scramble incoming data differently on different antennas for those users requiring frequency diversity type transmissions. When PRAS is activated for a particular allocation, each transmit antenna applies a different scrambling sequence to the data symbols that are transmitted in the allocation.

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： In an OFDM system the same Walsh code is used at the same time for a plurality of transmitters. The multiple transmitters can be from the same, or different devices (e.g., different base stations on the downlink, different terminals on the uplink). Each subcarrier/antenna combination will share a similar pilot Walsh code, except for the fact that the scrambled spread pilot signals will be phase shifted on some subcarriers of some antennas, based on the subcarrier/antenna combination.
