摘要： A communication system supports H-ARQ, AMC, active set handoff, and scheduling functions in a distributed fashion by allowing a mobile station (MS) to signal control information corresponding to an enhanced reverse link transmission to Active Set base transceiver stations (BTSs) and by allowing the BTSs to perform control functions that were supported by an RNC in the prior art. The communication system allows time and SIR-based H-ARQ flush functions at the BTSs during soft handoff (SHO), provides an efficient control channel structure to support scheduling, H-ARQ, AMC functions for an enhanced reverse link, or uplink, channel in order to maximize throughput, and enables an MS in a SHO region to choose a scheduling assignment corresponding to a best TFRI out of multiple assignments it receives from multiple active set BTS. As a result, the enhanced uplink channel can be scheduled during SHO without any explicit communication between the BTSs.

摘要： A base station communicates a positioning reference signal (PRS) to wireless communication devices over a downlink in a wireless communication system by encoding a PRS into a first set of transmission resources, encoding other information into a second set of transmission resources, multiplexing the two sets of resources into a subframe such that the first set of resources is multiplexed into at least a portion of a first set of orthogonal frequency division multiplexed (OFDM) symbols based on an identifier associated with the base station and the second set of resources is multiplexed into a second set of OFDM symbols. Upon receiving the subframe, a wireless communication device determines which set of transmission resources contains the PRS based on the identifier associated with the base station that transmitted the subframe and processes the set of resources containing the PRS to estimate timing (e.g., time of arrival) information.

摘要： Receiving units will switch between performing a DC bias suppression and not removing the DC distortion at the receiver depending on the amount of DC interference level observed/measured/estimated. Since the overall DC interference is from all uplink transmitters, potentially at different power levels, the amount of DC distortion can be measured based on the difference between the received power level and the expected power level on the DC sub-carrier. Additionally it can be estimated based on the number of active transmitters, their allocation bandwidth, power control target and/or a rough estimate of the DC distortion introduced by each active transmitter and also the distortion introduced by the receiver. Once this distortion level is estimated, a decision is then made whether or not to remove the DC distortion.
摘要翻译：接收单元将在执行直流偏置抑制之间进行切换，而不会根据观测/测量/估计的直流干扰电平的量消除接收机的直流失真。由于整个DC干扰来自所有上行链路发射机，潜在地处于不同的功率电平，所以可以基于DC子载波上的接收功率电平与预期功率电平之间的差异来测量DC失真量。此外，可以基于活动发射机的数量，其分配带宽，功率控制目标和/或由每个有源发射机引入的DC失真的粗略估计以及由接收机引入的失真来估计。一旦估计出该失真水平，则作出是否去除DC失真的决定。
