Abstract: 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.

Abstract: Techniques for sending control information in a wireless communication system are described. In an aspect, a UE spreads control information across frequency with a DFT and across time with an orthogonal sequence to obtain output data for the control information. In one design, the UE receives codewords for N HARQ processes in N downlink subframes, determines an ACK value for each HARQ process, codes N ACK values for the N HARQ processes to obtain ACK information, generates output data for the ACK information, and sends the output data in one of M uplink subframes. In another aspect, first control information is processed based on a first coding and multiplexing scheme utilizing code division multiplexing in time and frequency domains. Second control information is processed based on a second coding and multiplexing scheme utilizing code division multiplexing in time domain and spreading in frequency domain.

Abstract: Feedback information for multiple serving cells are transmitted on high speed dedicated physical control channel (HS-DPCCH). A slot format for transmitting feedback information is determined based on the number of configured secondary serving cells and whether multiple input multiple-output (MIMO) is configured in the serving cells. Spreading factor is reduced to 128 when two secondary serving cells are configured and MIMO is configured in at least one of the two configured secondary serving cells, or when three secondary serving cells are configured. The serving cells are grouped into feedback groups, each feedback group having one or more serving cells. Channel coding may be applied to feedback information for the feedback groups. The resulting encoded feedback information for the feedback groups is concatenated to form composite feedback information.

Abstract: Disclosed is multiplexing transmissions of Uplink Control Information (UCI) signals having variable payloads from User Equipments (UEs). The UCI transmission uses a first format type if its size is less than or equal to a predetermined values and it uses a second format type if its size is greater than a predetermined value. When the first format type is used the UE multiplexing is through a first method while when the second format type is used the UE multiplexing is through a second method which is different than the first method. The structure of the second format type is the same as the structure used for the transmission of data information by UEs. The UEs can also be grouped and UCI transmission can be triggered through the reception of control signaling addressing a group of UEs and indicating UCI transmission by a sub-group of UEs in the group of UEs.

Abstract: Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.
