摘要： To reduce inter-sector interference for “weak” users and combat a potentially large variation in interference levels observed by “strong” and weak users, system resources (e.g., frequency subbands) available for data transmission in a system are partitioned into multiple (e.g., three) disjoint sets. Each sector in the system is assigned one subband set. Neighboring sectors are assigned different subband sets such that the subband set assigned to each sector is orthogonal to the subband sets assigned to neighboring sectors. Each sector has an assigned subband set and an unassigned subband set, which contains all subbands not in the assigned set. Weak users in each sector (which are typically strong interferers to neighboring sectors) are allocated subbands in the assigned set. Strong users in each sector are allocated subbands in the unassigned set. The weak users in each sector are then orthogonal to strong interferers in neighboring sectors.

摘要： Method and apparatus for transmission of information in multiple access communication system is claim. Information using incremental redundancy is transmitted. A determination is made as to whether reverse link performance drops below a predetermined threshold. Determination of reverse link performance may be done in variety of ways, including use of a filter percentage of ACK erasures, measured error rates on the reverse link control channel, reverse link data channel error rates, and other methods. Upon determination of channel degradation, the access point can decide whether to ignore messages sent from the access terminal to instruct the access terminal to cease transmission.

摘要： Techniques for utilizing a capacity-based effective signal-to-noise ratio (SNR) to improve wireless communication are described herein. In an embodiment, a mobile terminal can determine the effective SNR from a forward link channel using pilot/data symbols. The mobile terminal can convey the effective SNR to a base station. In order to minimize transmission overhead, the mobile terminal can quantize the effective SNR prior to transmitting it to the base station. In another embodiment, the base station can determine the effective SNR from a reverse link. The base station can utilize the effective SNR to facilitate scheduling transmissions from the mobile terminal, transmitting power control commands to the mobile terminal, and determining a supporting data rate for the mobile terminal, for example. Suitable SNRs include constrained, unconstrained, average, and/or approximated effective SNRs. In addition, various filters, such as an averaging filter, can be utilized to further process the effective SNR.

摘要： For restrictive reuse, each cell (or each sector) is assigned (1) a set of usable subbands that may be allocated to users in the cell and (2) a set of forbidden subbands that is not used. The usable and forbidden sets for each cell are orthogonal to one other. The usable set for each cell also overlaps the forbidden set for each neighboring cell. A user u in a cell x may be allocated subbands in the usable set for that cell. If user u observes/causes high level of interference from/to a neighboring cell y, then user u may be allocated subbands from a “restricted” set containing subbands included in both the usable set for cell x and the forbidden set for cell y. User u would then observe/cause no interference from/to cell y. The subband restriction may be extended to avoid interference from multiple neighboring cells.
