    摘要: A method, an apparatus, and a computer program product for wireless communication are provided in which a first message to reconfigure an uplink transmission mode of a user equipment (UE) from a first uplink transmission mode to a second uplink transmission mode is transmitted. Further, a reconfiguration scheme to assure at least one of two or more second messages are recognizable by the UE during a transition period after transmission of the first message is implemented. In another example, a UE and eNB may be equipped to respectively transmit and receive a first message to reconfigure a SRS mode used by a UE. In such an aspect the first message may respectively indicate and be used to determine an SRS transmission port specified in a field capable of indicating a number of SRS transmission ports that is greater than a number of physical UE antenna ports.

    摘要: Techniques for receiving reference signals from multiple nodes and determining channel state information (CSI) for the nodes are disclosed. A user equipment (UE) may determine and report CSI for the multiple nodes to support data transmission to the UE. The nodes may transmit reference signals based on different configurations. The configuration for each node may indicate when, where, and how the node transmits its reference signal. The UE may determine CSI for different nodes and/or different combinations of nodes based on the reference signals transmitted by these nodes as well as an indication of which subframes to use to determine each CSI reported by the UE. The UE may report different CSIs for different subframes and may receive data transmission sent by a single node or a combination of nodes based on the reported CSIs.

    摘要: Techniques for supporting channel measurement and reporting in a wireless communication system are described. In one design, a cell transmits a cell-specific reference signal (CRS) used for channel estimation and coherent demodulation and a channel spatial information reference signal (CSI-RS) used for channel measurement and channel feedback reporting. The cell may transmit the CSI-RS less frequently than the CRS, or from more antenna ports than the CRS, or on fewer resource elements than the CRS, or a combination thereof. In one design, a user equipment (UE) determines at least one bandwidth part configured for the UE, with each bandwidth part covering at least one subband. The UE receives the CRS and CSI-RS from the cell, determines channel feedback information for the at least one bandwidth part based on the CSI-RS, sends the channel feedback information to the cell, and receives data transmitted by the cell based on the channel feedback information.

    摘要: A method includes receiving a cross-subframe assignment in a first subframe, targeting a second subframe in which a transmission power control (TPC) command is to be applied. The method may also include adjusting transmit power in accordance with the TPC command during a third subframe, a predefined number of subframes after the first subframe. Another method includes receiving a cross-subframe assignment in a first subframe. The cross-subframe assignment targets a second subframe in which a first TPC command is to be applied. The method may also include receiving a nominal grant in the first subframe that targets an identified subframe to which a second TPC command is to be applied. The method may also include adjusting the transmit power according to the first TPC command, the second TPC command or a function of the first TPC command and the second TPC command during the second subframe or the identified subframe.

    摘要: Systems and methodologies are described that facilitate reducing false detections of control channels during blind decode when multiple component carriers are configured. A UE can perform blind detection of control channels on a plurality of carriers, wherein each control channel detected can be validated to reduce false detections. In one aspect, a reference carrier can be selected, wherein one or more detected control channels are validated so long as one detected control channel is on the reference carrier. In another aspect, control channel can be bundled such that multiple control channel detections are required for validation. Moreover, dummy control channels can be introduced that provide UE with guidance during blind decoding, as well as provide validation of detections. Further, various combinations of a reference carrier, bundling, and/or a dummy control channel can be utilized.

    摘要: Techniques for performing frequency hopping in a wireless network are described. In an aspect, frequency hopping may be performed based on both cell identity (ID) and system time information. In one design, a user equipment (UE) may determine a cell ID of a cell and may obtain system time information for the cell. The UE may determine resources to use for transmission with frequency hopping based on the cell ID and the system time information. In one design, the UE may initialize a PN generator in each radio frame with an initial value determined based on the cell ID and a system frame number (SFN) for the radio frame. The UE may determine the resources to use for transmission based on a hopping function, a mirroring function, and a PN sequence from the PN generator. The UE may send a transmission on the resources to the cell.
