    摘要： A wireless communication device receives at least a section of a subframe from a base station in a wireless communication system. The subframe includes transmission resources multiplexed onto subcarriers of orthogonal frequency division multiplexed (OFDM) symbols. A first set of OFDM symbols includes a reference signal and at least a second set of OFDM symbols includes information other than the reference signal (e.g., channel-coded data). The wireless device determines which OFDM symbols of the subframe constitute the first set of OFDM symbols based on an identifier associated with a base station that transmitted the subframe. The wireless device may then process the reference signal from the OFDM symbols that are determined to be the first set of OFDM symbols. The wireless device may also determine which OFDM symbols of the subframe constitute the second set of OFDM symbols and process non-reference signal information from OFDM symbols of the second set.

    摘要： A method in a wireless communication User Equipment (UE) includes receiving a Physical Downlink Control Channel (PDCCH) message assigning a data transmission on a Physical Downlink Shared CHannel (PDSCH), wherein the PDCCH message includes scheduling information with a first New Data Indicator (NDI) bit field for a first transport block and a second New Data Indicator (NDI) bit field for a second transport block.

    摘要： A communication is provided that schedules both Distributed Virtual Resource Blocks (DVRB) and Localized Virtual Resource Blocks (LVRB) in a same frequency channel, thereby obtaining the benefits of frequency selective scheduling while minimizing the uplink feedback overhead. In one embodiment of the invention, the communication system assigns one or more downlink Physical Resource Blocks (PRBs) of multiple downlink Physical Resource Blocks (PRBs) to each user equipment (UE) given an LVRB to produce at least one reserved PRB and multiple non-reserved PRBs and assigns a part of each PRB of the multiple non-reserved PRBs to a UE given a DVRB. In another embodiment of the invention, the communication system assigns PRBs pre-reserved for localized transmission to UEs scheduled for LVRBs and assigns parts of multiple PRBs pre-reserved for distributed transmission to each UE given a DVRB.

    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.
