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： 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： Techniques for supporting distributed multiple-input multiple-output (MIMO) transmissions are described. In one design, a user equipment (UE) determines channel estimates for multiple cells and reports the channel estimates. The UE thereafter receives a data transmission sent by the multiple cells to the UE based on the channel estimates. The data transmission may include at least one data stream, and each data stream may be sent by one cell or the multiple cells to the UE. In another design, a UE determines first and second channel estimates for first and second cells, respectively, and reports the channel estimates. The UE then receives a first data transmission sent by the first cell to the UE based on the first channel estimate. The UE also receives a second data transmission sent by the second cell to another UE and steered away from the UE based on the second channel estimate.

摘要： Techniques for supporting broadcast, multicast, and unicast services in a cellular system are described. A Node B may multiplex data for broadcast and multicast services and data for unicast services on radio resources available for transmission. The Node B may periodically send scheduling information used to determine the radio resources carrying the broadcast and multicast services. In one design, the Node B may time division multiplex the data for the broadcast and multicast services and the data for the unicast services. The scheduling information may convey time unit(s) used for each broadcast or multicast service. In another design, the Node B may map the data for the broadcast and multicast services to time frequency blocks. The scheduling information may (i) convey the time frequency block(s) used for each broadcast or multicast service or (ii) point to control information conveying the time frequency block(s) used for each service.

摘要： Systems and methodologies are described that facilitate defining and utilizing hopping patterns to transmit broadband pilot signals in a wireless communications network. Portions of bandwidth can be dedicated to transmitting the broadband pilot data, and patterns can be utilized to hop across frequencies in given time periods to effectively utilize the entire dedicated bandwidth. Moreover, the periodicity for transmitting the data is configurable to allow devices requiring additional scheduling (e.g., high activity devices) to transmit the broadband pilot data more frequently. The hopping patterns can also hop across cyclic shifts of the patterns to provide optimum diversity for transmitting broadband pilot signals.

摘要： A communication system that facilitates transmissions in accordance with a single-carrier (SC) multiplexing scheme, a multi carrier (MC) multiplexing scheme or a combination thereof is disclosed. Based on various factors such as attributes associated with a UE (user equipment) or availability of resources, a base station can signal to the UE an appropriate multiplexing scheme to be adopted for particular transmissions. The UE can be scheduled for transmission in a semi-static mode wherein the UE employs the transmission scheme for a particular time interval or it may change the mode dynamically for different transmissions. For transmissions from the UE comprising a plurality of data streams with dissimilar attributes, the base station implements a MIMO (multiple input multiple output) system for the UE. This facilitates a UE to dynamically switch between or simultaneously adopt the various multiplexing schemes for communications and thereby fully utilize advantages associated with the different schemes.

摘要： Facilitating frequency hopping for single carrier, frequency division multiple access (SC-FDMA) transmission is described herein. By way of example, user data transmitted within a transmission allocation unit can be frequency shifted with respect to time based slots of the allocation unit. As a result, frequency hopping can be accomplished while preserving single carrier constraints and a low peak to average power ratio (PAPR). Furthermore, various frequency shifted mechanisms are disclosed to accomplish preservation of single carrier restraints. For example, a scheduler can select between cyclic frequency shifting, transposed frequency shifting, and multiplexing of frequency selective scheduled and frequency hopped data based on an audit of scheduled data for the transmission allocation unit. As a result, the reduction in interference achieved through frequency hopping can be combined with the low PAPR for various data allocation configurations.
摘要翻译：本文描述了用于单载波频分多址（SC-FDMA）传输的促进跳频。作为示例，在传输分配单元内传输的用户数据可以相对于分配单元的基于时间的时隙进行频移。结果，可以在保持单载波约束和低峰均功率比（PAPR）的同时完成跳频。此外，公开了各种频移机构来完成单载波约束的保存。例如，调度器可以基于对传输分配单元的调度数据的审计在循环频移，转置频移和频率选择性调度和跳频数据的复用之间进行选择。因此，通过跳频实现的干扰减少可以与用于各种数据分配配置的低PAPR相结合。

摘要： Techniques for quickly and efficiently performing handover are described. A user equipment (UE) may maintain a link with a serving cell and may communicate with this cell via the established link. The UE may have a candidate set of non-serving cells that are candidates for handover. The UE may maintain uplink synchronization with one or more non-serving cells in the candidate set, without having to maintain links with any of the non-serving cells. The UE may update uplink synchronization with the non-serving cells via an access procedure, e.g., send access probes to the non-serving cells and receive timing adjustments from these cells. One non-serving cell with which the UE has maintained uplink synchronization may be selected as a target cell for handover. The UE may then perform handover from the serving cell to the target cell, without performing uplink synchronization during the handover, which may improve handover latency and success rate.
