摘要： For soft handoff on the reverse link with restrictive reuse, a wireless terminal searches for pilots transmitted by sectors in a wireless system, measures the detected pilots, selects a serving sector (e.g., the strongest received sector), and identifies non-serving sectors that may receive high interference from the terminal. The serving sector assigns the terminal with subband(s) that are usable by the serving sector and unusable by the non-serving sectors. The terminal transmits data symbols on the assigned subbands to the serving and non-serving sectors. These sectors process the reverse link transmission from the terminal and obtain soft-decision symbols, which are estimates of the transmitted data symbols. The soft-decision symbols from co-located sectors may be combined and then decoded to obtain decoded packets. The sectors may also independently decode the soft-decision symbols, and the decoded packets from these sectors may be combined to obtain final decoded packets for the terminal.

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.

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： Systems and methodologies are described that facilitate resolving resource assignment conflicts between access terminals in a wireless communication environment. A first access terminal may receive a persistent, or “sticky” assignment of a set of resources, such as subcarriers. In the event that a second access terminal requires a brief resource assignment, a time-limited, or “non-sticky” resource assignment may be granted to the second access terminal. If a resource in the non-sticky assignment is already assigned to the first access terminal via the sticky assignment, the first access terminal may receive an indication of the conflict along with information related to a duration of the non-sticky assignment, may surrender the conflicted resource, and may resume control over the conflicted resource after the termination of the non-sticky assignment.

摘要： Systems and methodologies are described that facilitate dynamically supplementing resource assignments to mobile devices in a wireless network environment without requiring transmission of replacement assignments. Supplemental assignments can be generated based on information related to mobile device need and resource availability. Additionally, assignment validation can be performed to mitigate generation of conflicting resource assignment to multiple devices. Moreover, resource assignments can be persisted for a mobile device.

摘要： A method and apparatus to determine whether a transmission was successfully received in a multiple access communication system is claimed. First and second encoded data packets are received and decoded. The first and second data packets are then re-encoded, and correlated to determine whether the first and second re-encoded data packets are the same. If there is a high degree of correlation, an indicator of acknowledgement is transmitted to indicate that there is a high degree of correlation between the first and second re-encoded data packets. If there is a low degree of correlation, a determination is made that the previously transmitted indicator of acknowledgement was correctly received.

摘要： Systems and methodologies are described that facilitate communication by supplying an immediate re-send of an assignment, when such assignment is not decoded by an access node (“AN”). In one embodiment, the assignment to AT can be re-sent immediately, hence mitigating a requirement for the AT to indicate that “Yes” the assignment was received, or “No” that the assignment was not received. Accordingly, if the AN does not decode the assignment, the assignment is re-sent, and a request latency can be removed.
