摘要： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

摘要： Techniques for sending messages for system access are described. In one aspect, a user equipment (UE) sends a first message with power headroom and/or buffer size information for system access. A Node B determines at least one parameter (e.g., a resource grant, power control information, etc.) based on the power headroom and/or buffer size information. The Node B sends a second message with the parameter(s). The UE sends a third message based on the parameter(s), e.g., with uplink resources indicated by the resource grant, with transmit power determined based on the power control information, etc. In another aspect, the UE sends a radio environment report in the third message.

摘要： 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.

摘要： Techniques for sending multiple-input multiple-output (MIMO) transmissions in wireless communication systems are described. In one design, a transmitter sends a first reference signal via a first link, e.g., a cell-specific reference signal via the downlink. The transmitter receives channel quality indicator (CQI) information determined by a receiver based on the first reference signal. The transmitter also receives a second reference signal from the receiver via a second link, e.g., a sounding reference signal via the uplink. The transmitter obtains at least one MIMO channel matrix for the first link based on the second reference signal. The transmitter determines at least one precoding matrix based on the at least one MIMO channel matrix, e.g., in accordance with ideal eigen-beamforming or pseudo eigen-beamforming. The transmitter then sends a data transmission to the receiver based on the at least one precoding matrix and the CQI information.

摘要： Systems and methodologies are described that facilitate employing constrained frequency hopping of downlink reference signals. Constrained frequency hopping of reference signals provides a sufficiently large set of frequency hopping patterns while enhancing channel estimation. Respective subsets of resource elements can be selected to carry reference signals from a plurality of antennas for a first subframe of a sequence. Further, respective subsets of resource elements used to carry reference signals from the plurality of antennas for a second subframe can be constrained based upon the respective subsets for the first subframe. Moreover, the first subframe frame and the second subframe (and similarly any additional subframes in the sequence) can be transmitted. An access terminal receiving the sequence of subframes can combine reference signals sent from common antennas at common frequency locations in the plurality of subframes and perform channel estimation as a function of the combined reference signals.

摘要： Systems and methodologies are described that facilitate employing periodic closed loop power control corrections in a wireless communication environment. A periodic power control command can be sent over a downlink to control and/or correct an uplink power level employed by an access terminal. Each periodic power control command can be generated based upon an uplink periodic transmission sent from the access terminal. The periodic power control commands can be communicated via a Physical Downlink Control Channel (PDCCH) or in-band signaling. Moreover, access terminals can be grouped to enhance efficiency of downlink transfer of the periodic power control commands. The periodic power control commands can be halted upon access terminal uplink resources being deallocated. For instance, these resources can be deallocated after an inactivity period of the access terminal. Thereafter, the access terminal can initiate random access (e.g., leveraging open loop mechanisms) to resume periodic power control command transmission.

摘要： Systems and methodologies are described that facilitate arrangement and transmission of control information in a wireless communication system. As described herein, a scheduled transmission of acknowledgement (ACK) signaling and channel quality information (CQI) signaling in a common subframe can be adapted for network implementations with limited link budget wherein ACK signaling is configured for repetition over multiple subframes to ensure a desired error rate level for the ACK signaling. To these ends, various aspects described herein facilitate modification of a coding rate applied to ACK signaling to be transmitted with data based on a repetition factor of the ACK signaling. Additionally and/or alternatively, various aspects described herein facilitate dropping of CQI signaling and transmission of only ACK signaling on subframes where CQI and ACK signaling are to be transmitted substantially simultaneously and ACK transmission is configured for repetition over multiple subframes.

摘要： Systems and methodologies are described that facilitate allocation of uplink acknowledgement (ACK) resources for a wireless communication system. Various aspects described herein facilitate explicit creation and transmission of a bundled assignment of downlink communication resources and uplink resources for ACK transmission, thereby facilitating overhead-efficient ACK allocation for users that can communicate pursuant to a persistent resource assignment without requiring scheduling information from an associated control channel. Additionally, indexing schemes for uplink ACK resources are provided herein to facilitate ACK allocation for systems in which both scheduled and persistent users can communicate at a common transmission time interval (TTI).

摘要： Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations.
