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 downlink 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比特在传输之前被联合编码，以维持低的峰均比（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来部分地通过假设UE在下行链路上响应授权，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 determining control region parameters related to a plurality of carriers and/or coordinated multiple point (CoMP) access points. Wireless devices can receive control region parameters related to the carriers or CoMP access points from a serving access point over control channel resources. Additionally or alternatively, wireless devices can assume all carriers or CoMP access points have substantially the same control region as indicated in a control format indicator channel from the serving access point or based on a configured value.

摘要： Providing for mixed single carrier and multi-carrier uplink transmission in a wireless communication environment is described herein. By way of example, a network is provided that can identify uplink capabilities or restrictions of respective devices of a mixed population of mobile devices, and schedule single carrier or multi-carrier transmissions accordingly. In some aspects, different subsets of multi-carrier transmission can be given priority over other subsets. Based on the priority, the network can schedule/modify relative transmit powers for respective subsets, accommodate power constraints of higher level networking protocols, and optionally give priority to one or more of the distinct transmissions. In addition, priority can be given to respective subsets of the multi-carrier transmission, to ensure high quality or reliability for important transmissions. Thus, provided is an integrated network that accommodates a powerful mix of single carrier and multi-carrier services for a mixed population of mobile devices.

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： 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： A system and method for inter-cell interference mitigation in FDM systems is provided. The system provides for increased efficiency with load metric data generated per subband for both serving and neighboring non-serving cells. The system robustly provides for sharing load metric date per subband through a backhaul channel as well as directly from cell to adjacent cell. Furthermore, a UE based communication system allows UE reduction of assigned load controls based on directly reading a neighboring cells' load metrics. The system thus robustly handles various cell types (e.g. synchronous or asynchronous) and a variety of UE capabilities while providing increased efficiency in managing inter-cell interference.

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. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.

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： Systems and methodologies are described that provide techniques for efficient cell search in a wireless communication system. In one aspect, a frequency reuse pattern can be generated by applying frequency shifts to reference signals transmitted from cells that provide coverage for a NodeB based on cell IDs or cell group IDs for the cells. The frequency shifts applied to reference signals can then be utilized as a basis for multiplexing reference signals from different cells using frequency division multiplexing (FDM) or a combination of FDM and other multiplexing techniques. Other adjustments to reference signals transmitted from respective cells, such as transmit power adjustments, can further be made to improve detection performance.

摘要： Techniques are provided for the suppression of reference signal transmissions to enable sensing in cognitive radio communications. In one example, there is provided a method, operable by a network entity (e.g., evolved Node B), that may involve communicating with another network entity to determine parameters of a quiet period, the parameters comprising at least one of when the quiet period occurs and duration of the quiet period. The method may involve transmitting a reference signal in a first channel exclusively during a first plurality of subframes of a first frame period, wherein the first frame period further includes a quiet period during which no signals are transmitted, and performing during the quiet period a sensing operation with respect to the first channel.
