摘要： Techniques for transmitting synchronization signals to assist user equipments (UEs) perform cell searches are described. In one design, a base station for a cell may generate and transmit a primary synchronization signal and a secondary synchronization signal, which may be used by the UEs for initial cell search at power up. The base station may also generate and transmit one or more beacon signals, which may be used by the UEs for neighbor cell search to detect for neighbor cells. The number of beacon signals to transmit and the set of subcarriers usable for each beacon signal may be determined based on the system bandwidth. Each beacon signal may be mapped to one subcarrier in the set of subcarriers in each beacon symbol period. This one subcarrier may be determined based on a beacon hopping pattern or a beacon code and may be dependent on a cell identifier (ID).

摘要： Techniques for efficiently supporting frequency selective scheduling (FSS) and frequency diversity scheduling (FDS) are described. In one design, a first transmission for an FSS user may be mapped to a subband selected for this user from among at least one subband in a first frequency region of the system bandwidth. The first transmission may be mapped to a fixed portion or different portions of the selected subband in different time intervals. A second transmission for an FDS user may be mapped across multiple subbands in a second frequency region of the system bandwidth. The second transmission may be mapped to different subbands or different resource blocks in the second frequency region in different time intervals. Each time interval may correspond to a symbol period, a slot, a subframe, etc. The frequency hopping may be performed based on a fixed hopping pattern or a pseudo-random hopping pattern.

摘要： Techniques for supporting MIMO transmission are described. User equipments (UEs) are classified into a first group of UEs to be scheduled individually and a second group of UEs that can be scheduled together. The classification may be based upon the number of transmit and receive antennas, sector loading, data requirements, long-term channel statistics, the number of UEs, etc. Channel quality indicator (CQI) information received from the UEs is interpreted in different manners depending on the groups to which the UEs belong. A single UE may be selected at a time from the first group or multiple UEs may be selected at a time from the second group for MIMO transmission. A MIMO transmission may be sent to a single UE in the first group or multiple UEs in the second group at rates selected based upon the CQI information.

摘要： Techniques to mitigate inter-cell interference using joint time and frequency division are described. A frequency band is divided into multiple non-overlapping frequency subbands. The transmission timeline is divided into T in and T out time intervals. Data is exchanged with users in at least one inner region of a cell on the entire frequency band in the T in time intervals. Data is exchanged with users in multiple outer regions of the cell on the multiple frequency subbands in the T out time intervals. The frequency band may be partitioned into three frequency subbands. Data may then be exchanged with users in first, second and third outer regions on first, second and third frequency subbands, respectively. The regions in which the users are located may be determined based on pilot and/or other measurements.

摘要： Methods and apparatus provide for channel selection within a wireless network. A multi-channel wireless access point may select a channel for a wireless device requesting data or voice service based on the transmit times of each channel supported by the multi-channel wireless access point. The transmit times may be based on the physical rates of the devices assigned to each channel. The channel may also be selected based on the quality of service requested by the wireless device, the medium occupancy of each channel, or the number of wireless devices assigned to each channel. Alternatively the wireless device may select the channel for assignment based on channel statistics information provided by the multi-channel wireless access point. This information may be provided through one or more beacon signals, or supplied in response to a request for the information from a wireless device.

摘要： In release 8 of the LTE standard ("Rel-8"), a control channel and its associated data channel for downlink may be found in the same subframe. However, decoding of the control channel may be difficult if there is strong interference from different cells (e.g., due to interference from strong/dominant interfering cells). Communication in a dominant interference scenario may be supported by performing inter-cell interference coordination (ICIC). For example, cells may partition subframes to avoid interference. For some embodiments, allocating resources for a downlink data channel on one subframe may come from a PDCCH on a different subframe, which can be referred to as a cross-subframe assignment. Certain aspects of the present disclosure provide subframe-specific search spaces that may be used when there is at least one cross-subframe assignment in a subframe.
摘要翻译：在LTE标准（“Rel-8”）的版本8中，可以在同一子帧中找到用于下行链路的控制信道及其相关联的数据信道。然而，如果存在来自不同小区的强干扰（例如，由于来自强/主导干扰小区的干扰），则控制信道的解码可能是困难的。可以通过执行小区间干扰协调（ICIC）来支持主要干扰场景中的通信。例如，单元可以分割子帧以避免干扰。对于一些实施例，在一个子帧上为下行链路数据信道分配资源可以来自不同子帧上的PDCCH，其可以被称为跨子帧分配。本公开的某些方面提供了子帧专用的搜索空间，其可以在子帧中存在至少一个跨子帧分配时使用。

摘要： Systems and methods for facilitating inter-cell interference coordination using resource partitioning are described. A UE may receive or determine information related to received interference and/or future scheduling. The information may be communicated to a serving base station, which may use the information to allocate uplink or downlink resources between cells. The uplink and/or downlink resource may be partitioned in subbands to mitigate interference from adjacent network nodes. The eNBs may communicate, such as directly, via a backhaul connection, and/or between UEs to configure interference coordination and signaling.

摘要： In 3GPP LTE, the uplink ACK and CQI bits are jointly coded prior to transmission to maintain a low peak to average ratio (PAR) waveform. Further, when data needs to be transmitted, the uplink control channels are multiplexed with data prior to transmission. However, due to errors on downlink (DL) and uplink (UL) assignments, an evolved Base Node (eNB) receiver needs to employ a set of rules to decode the control channels, to minimize the number of blind decoding hypotheses. This innovation describes the rules employed by a receiver to reduce complexity and computational overhead in part by assuming that the UE is responding to grant on the download while providing for combinations in which one or more types of grants are not received. Energy detection in accordance with metrics and normalizing for differing power controls enables selecting the correct combination for decoding.
摘要翻译：在3GPP LTE中，上行链路ACK和CQI比特在发送之前被联合编码以保持低的峰值平均比（PAR）波形。此外，当需要发送数据时，将上行链路控制信道与传输之前的数据进行多路复用。然而，由于下行链路（DL）和上行链路（UL）分配上的错误，演进的基站（eNB）接收机需要采用一组规则来解码控制信道，以使盲目解码假设的数量最小化。该创新描述了接收机采用的规则，以部分地通过假设UE在下载时响应授权，同时提供未接收到一种或多种类型的授权的组合，来降低复杂性和计算开销。能量检测按照度量标准化和不同的功率控制标准化，可以选择正确的组合进行解码。

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.
