摘要： Techniques for supporting communication in a wireless network are described. In an aspect, association and resource partitioning may be performed jointly to select serving base stations for user equipments (UEs) and to allocate available resources to base stations. In another aspect, adaptive association may be performed to select serving base stations for UEs. In one design, a base station computes local metrics for different possible actions related to association and resource partitioning (or only association). The base station receives local metrics for the possible actions from at least one neighbor base station and determines overall metrics for the possible actions based on the computed and received local metrics. The base station determines serving base stations for a set of UEs and resources allocated to the set of base stations (or just serving base stations for the set of UEs) based on the overall metrics for the possible actions.

摘要： In wireless communication systems, received signal estimation and detection is computationally intensive. During such processing, received signal matrices may be conditioned prior to inversion to improve stability. In particular, code domain conditioning, followed by time domain conditioning prior to inversion results in improved receiver performance. Such code and time domain conditioning may be particularly suited to a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system where code values are not averaged out of a received signal matrix.

摘要： Timing acquisition may be performed without typical correlation computations by determining a power of a received signal at certain points in time and using the determined power to identify gaps in the received signal. By determining gaps in the received signal, frame timing may be estimated, particularly in time-division networks where the location of guard periods within a frame is known. Gap detection may thus be used for timing acquisition.

摘要： Systems and methods are described to supply positioning reference signal (PRS) in a telecommunication system. A base station supplies a PRS sequence according at least to a time-frequency pattern of modulation symbols, wherein the time-frequency pattern assigns a modulation symbol to each frequency tone in a block of time-frequency resources allocated to transmit PRS. The base station associates a modulation symbol in the time-frequency pattern with a reference symbol in the PRS sequence through a mapping that represents the time-frequency pattern. The PRS sequence is conveyed to user equipment through delivery of a set of modulation symbols established through the mapping. Different time-frequency patterns can be exploited based on time-structure of a radio sub-frame. The user equipment receives the PRS sequence according to at least the time-frequency pattern of modulation symbols and utilizes at least the PRS sequence as part of a process to produce a location estimate.

摘要： Techniques for performing adaptive resource partitioning are described. In one design, a node computes local metrics for different possible actions related to resource partitioning to allocate available resources to a set of nodes that includes the node. Each possible action is associated with a set of resource usage profiles for the set of nodes. The node sends the computed local metrics to at least one neighbor node in the set of nodes. The node also receives local metrics for the possible actions from the neighbor node(s). The node determines overall metrics for the possible actions based on the computed local metrics and the received local metrics. The node then determines allocation of the available resources to the set of nodes based on the overall metrics. For example, the node may select the action with the best overall metric and may utilize the available resources based on a resource usage profile for the selected action.
