摘要： A method for allocating resources in a wireless communications environment comprises receiving a mapping between a first hop-port and frequency range, and determining whether to map a second access terminal to a second hop-port that is mapped to at least the same frequency range during a substantially similar instance in time, the determination made as a function of characteristics relating to a first access terminal associated with the first hop-port. The method can further include determining that the first access terminal is a candidate for employing Space-Division Multiple Access (SDMA), and mapping the second-hop port and associating the second access terminal with the second hop-port when the second access terminal is also a candidate for employing SDMA.

摘要： A signaling channel that punctures traffic channels is used to send signaling, e.g., acknowledgments (ACKs). To send signaling, resources for the signaling channel are determined, e.g., based on a frequency hopping pattern. Signaling is spread with a spreading code (e.g., a Walsh code) to generate spread signaling, which is mapped to the resources for the signaling channel. Each resource may be partitioned into multiple clusters. A signaling message may be mapped to different clusters to achieve diversity. Traffic data may also be mapped to other resources for a traffic channel assigned for use. Traffic data mapped to the other resources for the signaling channel is punctured. The mapped signaling and traffic data are further processed (e.g., for OFDM or SC-FDMA) and transmitted.

摘要： A wireless communication system can implement beamforming across multiple omni-directional antennas to create beams at different spatial directions. The communication system can arrange the beams in sets, with each set arranged to provide substantially complete coverage over a predetermined coverage area. The communication system can arrange the multiple SDMA beam sets to support substantially complementary coverage areas, such that a main beam from a first set provides coverage to a weak coverage area of the second beam set. The wireless communication system assigns or otherwise allocates substantially orthogonal resources to each of the beam sets. The wireless communication system allocates resources to a communication link using a combination of beam sets and substantially orthogonal resources in order to provide improved coverage without a corresponding increase in interference.

摘要： Apparatuses and methodologies are described that increase system capacity in a multi-access wireless communication system. Spatial dimensions may be utilized to distinguish between multiple signals utilizing the same channel and thereby increase system capacity. Signals may be separated by applying beamforming weights based upon the spatial signature of the user device-base station pair. Grouping spatially orthogonal or disparate user devices on the same channel facilitates separation of signals and maximization of user device throughput performance. User devices may be reassigned to groups periodically or based upon changes in the spatial relationships between the user devices and the base station.

摘要： A shared signaling channel can be used in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system to provide signaling, acknowledgement, and power control messages to access terminals within the system. The shared signaling channel can be assigned to a predetermined number of sub-carriers within any frame. The assignment of a predetermined number of sub-carriers to the shared signaling channel establishes a fixed bandwidth overhead for the channel. The actual sub-carriers assigned to the channel can be varied periodically, and can vary according to a predetermined frequency hopping schedule. The amount of signal power allocated to the signaling channel can vary on a per symbol basis depending on the power requirements of the communication link. The shared signaling channel can direct each message carried on the channel to one or more access terminals. Unicast messages allow the channel power to be controlled per the needs of individual communication links.

摘要： Techniques for sending acknowledgement (ACK) and/or other control information with a configurable timeline are described. A receiver may have limited processing resources and may need different amounts of time to process different amounts of data. The receiver may send ACK information earlier (or later) if less (or more) receive processing time is required. In one design, the receiver may receive a transmission of data in accordance with a grant, decode the received transmission to recover the data, and determine ACK information based on decoding result. The receiver may determine a frame to send the ACK information based on the grant. The determined frame may be one of multiple frames available for sending the ACK information. For example, different grant sizes may be associated with different frames. The receiver may send the ACK information for the transmission of data in the determined frame.

摘要： Signaling-only access may be established with an access node (104) under certain circumstances such as, for example, upon determining that a node (102) is not authorized for data access at the access node (102). A node (104) that is not authorized for data access at an access node (104) may still be paged by the access node (104) through the use of signaling-only access. In this way, transmissions by the access node (104) may not interfere with the reception of pages at the node (302). A first node may be selected for providing paging (102) while a second node (106) is selected for access (304) under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.
摘要翻译：在特定情况下，例如在确定节点（102）不被授权用于在接入节点（102）处的数据访问时，可以在接入节点（104）上建立仅信令访问。在接入节点（104）处未被授权用于数据接入的节点（104）仍然可以由接入节点（104）通过使用仅信令接入进行寻呼。以这种方式，接入节点（104）的传输可能不干扰节点（302）处的页面的接收。可以选择第一节点来提供寻呼（102），而在某些情况下例如在确定第二节点提供比第一节点更理想的服务之后，第二节点（106）被选择用于接入（304）。

摘要： Systems and methodologies are described that facilitate resource scaling for inter-access point fairness in a wireless communication system. As described herein, an offered load of an access point can be determined based on one or more loading metrics relating to associated terminals, throughput, data rate, quality of service (QoS), or the like. Based on the determined offered load of an access point, resources used by the access point and/or power utilized for communication over those resources can be scaled based on a comparison of the offered load of the access point to a nominal or default offered load. Centralized techniques for resource scaling are described herein, wherein one or more centralized controllers coordinate resource scaling with respective access points via backhaul messaging. In addition, distributed techniques for resource scaling are described herein, wherein neighboring access points communicate with each other via over-the-air messaging to determine a local optimal resource apportionment.

摘要： Systems and methodologies are described that facilitate employing distributed frequency planning and reuse factor optimization based upon forward link and/or reverse link interference management techniques. An optimal reuse factor for a base station can be determined based upon a metric that evaluates levels of service associated with neighboring base stations. Moreover, a subset of available resource sets can be selected for use by the base station; thus, a base station specific collection of resource sets can be formed through such selection. Further, mappings of each resource set to a set of physical resources can be disseminated in a network or portion thereof. According to another example, frequency hopping can be constrained to use of resources within a resource set (rather than across more than one resource set) as provided in a base station specific hopping pattern.
