摘要： Systems and methodologies are described that facilitate cycling through precoders for transmitting wireless network communications in a time domain. The precoders can be cycled according to a precoder sequence for each data symbol transmission. When the last precoder is selected the cycle can begin again, a new precoder sequence can be received or defined, and/or the like. A precoder sequence related to a subset of precoders present in a wireless device can be defined sequentially, cyclically shifted according to an identifier or one or more communications parameters, randomly, pseudo-randomly according to an identifier or one or more communications parameters, and/or the like. In addition, the precoder sequence can be utilized to select a precoder for one or more retransmissions. Such cycling of precoders can increase transmit diversity.

摘要： In a Time Division Duplex (TDD) system, downlink and uplink communications share the same bandwidth but occupy different subframes. When the downlink has more subframes than the uplink, special treatment on user equipment (UE) ACK/NACK feedback is needed. One uplink may need to ACK multiple downlink subframes. A downlink association without unnecessary ACK/NACK resources sets accounts for subframes for which ACK feedback is not desired. Examples of such subframes include: a blank subframe; an almost blank subframe where only a cell specific Reference Signal (RS) is transmitted; a Time Division Multiplex (TDM) partition in which an evolved NodeB (eNB) only transmits a Physical Downlink Shared Channel (PDSCH) or a Physical Downlink Control Channel (PDCCH) indicating Semi-persistent scheduling (SPS) at certain downlink subframes; a Downlink Pilot Timeslot (DwPTS) with a certain special subframe configuration where an eNB does not send the PDSCH and the UE is not in SPS active mode in the DwPTS; and a Multi-Media Broadcast over a Single Frequency Network (MBSFN) subframe when the UE is not in SPS active mode in the MBSFN subframe.

摘要： Techniques for transmitting a reference signal on multiple non-contiguous clusters of resources are described. A user equipment (UE) may be scheduled for data transmission on the multiple non-contiguous clusters, and each cluster may cover a set of contiguous subcarriers. The UE may generate the reference signal based on at least one reference signal (RS) sequence using code division multiplexing (CDM) or frequency division multiplexing (FDM). In an design, the UE generates the reference signal with CDM based on a single RS sequence having a length matching the total length of the multiple non-contiguous clusters. In another design, the UE generates the reference signal with CDM based on one RS sequence for each cluster. In yet another design, the UE generates the reference signal with FDM and transmits the reference signal on a subset of all subcarriers for the multiple non-contiguous clusters.

摘要： In a wireless communication system, from available data resource elements (REs) in a subframe, REs are assigned to transmissions of a reference signal, thereby resulting in a plurality of remaining data REs. Furthermore, REs from the plurality of remaining data REs are assigned for data transmission to a wireless device in groups of a predetermined number of REs such that all assigned data REs within a group are within a predetermined number of symbols of each other in time domain and within a second predetermined number of subcarriers of each other in frequency domain, thereby resulting in at least one ungrouped RE.

摘要： Techniques for handling inconsistent control information in a wireless communication system are described. In an aspect, inconsistent control information is handled in different manners for the downlink and uplink. In one design, a user equipment (UE) receives a first grant with first control information for a first data transmission and also receives a second grant with second control information for a second data transmission. The UE determines that the second control information is inconsistent with the first control information, e.g., due to the two grants conveying different transport block sizes. The UE determines whether to retain or discard the second grant based on whether the two grants are for data transmissions on the downlink or uplink. In one design, the UE retains the second grant if the two grants are for data transmissions on the downlink and discards the second grant if the two grants are for data transmissions on the uplink.

摘要： Techniques for performing channel interleaving to achieve similar SINRs for multiple code blocks are described. In one design, a transmitter station (e.g., a base station or a UE) determines a plurality of resource groups assigned for data transmission. Each resource group includes a plurality of resource elements formed by a cluster of subcarriers in a time interval. The transmitter station partitions a transport block into a plurality of code blocks, processes each code block to obtain data symbols for that code block, and maps the data symbols for each code block to at least one resource element in each of the plurality of resource groups. The transmitter station transmits the mapped data symbols for the plurality of code blocks to a receiver station. In one design, the transmitter station receives an ACK or a NACK for the transport block and retransmits all code blocks if a NACK is received.
