    摘要: Methods and apparatuses are provided for bundling resource blocks (RB) for varying bandwidth scenarios in wireless communication. Where multiple access points form a coordinated multiple point (COMP) set for a device. the access points may be configured to use a common RB bundling size for precoding transmissions to the device. In another aspect, where a device is allocated a bandwidth and a bandwidth extension, a RB bundling size may be determined for the bandwidth and bandwidth extension, jointly or individually. The RB bundling size may be determined based on the bandwidth or on the bandwidth and the bandwidth extension.

    摘要: A precoding scheme to accommodate user equipment (UEs) having higher Doppler speeds. In such transmission schemes, a different precoding matrix is applied to each orthogonal frequency division multiplex (OFDM) symbol in the transmission stream. Additionally, a downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE is able to read the set of parameters as applied to the selected transmission scheme.

    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 sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

    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 accordance with one or more aspects and corresponding disclosure thereof, various aspects are described in connection with channel quality indicator (CQI) feedback in connection with one or more downlink carriers. An anchor carrier scheme is employed to provide channel quality indicator (CQI) feedback of one or more downlink carriers. An indication is set to identify that a designated uplink carrier is used to convey the CQI feedback. An uplink carrier is selected from a set of uplink carriers as an anchor carrier to convey the CQI feedback. CQI feedback is transmitted for one or more downlink carriers using the designated carrier.
