摘要： Methods and apparatus for beamforming for femtocells, such as in LTE wireless networks, to provide inter-cell coordination and interference mitigation are disclosed. A macrocell user equipment (UE) may determine information regarding an interfering femtocell node, such as a home eNodeB (HeNB). The information may be sent directly or indirectly, such as by a backhaul communication link, to the HeNB. The HeNB may adjust an output based on the information. The information may include spatial channel information, which may be used for beamforming at the HeNB output so as to mitigate interference in the direction of the UE.

摘要： Providing for resource-specific interference reporting to facilitate short-term channel quality and transmission parameterization in wireless communications is provided herein. By way of example, a UE observing high interference can utilize reference signals of a second UE (e.g., that observes less interference) for short-term channel quality measurements. These measurements can be on an order of one or two signal subframes, or less, to reflect interference resulting from distinct scheduling decisions of an interfering transmitter. Based on the short-term channel quality measurements, a base station serving the UE can initiate detailed interference mitigation, perform scheduling decisions that compensate for distinct parameterization of the interfering cell, or the like. This can result in improved wireless communications even for UEs observing very high wireless interference.

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： Techniques for reporting channel state information (CSI) are described. A user equipment (UE) may receive data transmission from one or more cells among a plurality of cells and may report CSI for each of the plurality of cells. In an aspect, the UE may generate CSI with different quantization granularity (e.g., different codebook sizes), or different frequency granularity (e.g., different subband sizes), and/or different time granularity (e.g., different reporting intervals) for different cells based on the performance impact of each cell for data transmission to the UE. The performance impact of each cell may be determined based on a long-term channel gain or received power of the cell at the UE. The UE may quantize the CSI for each cell based on the codebook size for the cell. The UE may generate the CSI for each cell based on the subband size and/or the reporting interval for the cell.

摘要： Providing for wireless communication involving supplemental wireless nodes is described herein. By way of example, prior signaling is employed between a macro base station and a set of associated supplemental nodes to support pending wireless communication with a user terminal. In some aspects, the prior signaling can include control or data traffic transmitted to or received from the user terminal. In addition, the supplemental nodes can synchronize transmission or reception of the control or data traffic transmissions with similar transmission or reception of the macro base station. In some aspects, the supplemental nodes can also replicate pilot signal transmissions on OFDM symbols employed by the macro base station for pilot signals, to give consistent downlink channel for both traffic and pilot signals. Accordingly, the user terminal observes consistent pilot transmissions over various time slots, as well as concurrent traffic transmissions that can generally be decoded with a common reference signal.

摘要： Estimating a channel impulse response (CIR) for a wireless transmission, for example a multimedia broadcast multicast services single frequency network (MBSFN) transmission, may be performed by a receiver of an wireless subframe, without requiring operational memory in excess of what is needed for CIR estimation of unicast signaling, while providing enhanced delay spread coverage. The wireless subframe may be a MBSFN subframe. The receiver may form an aggregate vector of pilot tones extracted from an OFDM reference symbol of an wireless subframe. The receiver may subsample the aggregate vector to obtain a plurality of sub-vectors each comprising a distinct subsampling phase. The receiver may process the plurality of sub-vectors using an inverse fast Fourier transform to obtain time domain representations of each of the sub-vectors. The receiver may combine the time domain representations in various ways to obtain a CIR estimate for the wireless subframe.

摘要： Providing for improved implementation of supplemental wireless nodes in a wireless base station deployment is described herein. By way of example, a donor base station is configured to send a schedule of data transmission to and from a set of UEs served by the base station, and further can provide the schedule and identifiers for the set of UEs to one or more wireless nodes serving the base station. Respective access channel measurements between respective UEs and respective wireless nodes can be forwarded to the base station, which in turn can identify optimal access channels for the set of UEs. Additionally, the donor base station can schedule multiple data transmissions on these access channels in a common transmission time slot, to achieve cell-splitting gains for the data transmissions. Range boosting, differential coding, and supplemental channel quality mechanisms are also provided for various wireless communication arrangements described herein.

摘要： Methods, systems, and devices for wireless communication are described. A transmitting device may identify a duration of a slot used for communications with a receiving device. The transmitting device may determine that the communications with the receiving device comprises frequency division duplexing (FDD) communications. The transmitting device may transmit communications to the receiving device during a first portion of the slot, a duration of the first portion being less than the duration of the slot and the duration of the first portion is based at least in part on the determination that the communications comprise FDD communications. The transmitting device may select, based at least in part on the determination that the communications comprise FDD communications and that the communications are transmitted during the first portion of the slot, a hybrid automatic repeat request (HARQ) scheme to use during the communications.
