摘要： Shared spectrum operation is disclosed for sharing spectrum among multiple wireless deployments. Coordination procedures between and among 2nd and 3rd Tier deployments include the use of beacons transmitted by the 2nd Tier for clearing access to spectrum occupied by 3rd Tier users and multiple 3rd Tier deployments sharing resources using a group-listen before talk (LBT) protocol, rather than a per-node LBT protocol. The 2nd Tier beacon signals are transmitted to alert 3rd Tier users of their presence, which, upon detection, will leave the particular spectrum within a predetermined time. For the shared LBT protocol, the 3rd Tier deployments share the channel with each other through an LBT with random backoff, in which the start time of clear channel assessment (CCA) procedure and the random backoff values are synchronized among nodes of the same deployment.

摘要： Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. A first method includes performing clear channel assessment (CCA) to determine availability of an unlicensed spectrum, transmitting a request-to-send (RTS) signal to a set of user equipments (UEs) using the unlicensed spectrum when a determination is made that the unlicensed spectrum is available, and receiving, in the unlicensed spectrum, a common clear-to-send (CTS) signal and an individual CTS signal from one or more of the UEs in response to the RTS signal. A second method includes transmitting an RTS signal in an unlicensed spectrum or a V-RTS signal in a licensed spectrum, addressed to a set of UEs, and transmitting a CTS-to-self signal in the unlicensed spectrum along with the transmission of the V-RTS signal.

摘要： In macro/RRH setups, channel state information reference signals (CSI-RS) and demodulation reference signals (DM-RS) may be used to decouple control and data transmission. Data transmission (e.g. for LTE Rel 10 and beyond) may be based on CSI-RS and DM-RS, while control may be received from a different set of cells or TxPs via CRS. Certain aspects of the present disclosure introduce a reporting framework, in which configuration of data-serving cells/TxPs may be carried out based on CSI-RS. In certain aspects, a new concept of CSI-RS groups, i.e., a set of CSI-RS ports that a UE considers as one group for precoding matrix indicator (PMI)/channel quality indicator (CQI)/rank indicator (RI) reporting, may be defined.
摘要翻译：在宏/ RRH设置中，信道状态信息参考信号（CSI-RS）和解调参考信号（DM-RS）可用于去耦合控制和数据传输。数据传输（例如，对于LTE Rel 10及其以外）可以基于CSI-RS和DM-RS，而可以经由CRS从不同的小区集合或TxP接收控制。本公开的某些方面引入了报告框架，其中可以基于CSI-RS来执行数据服务小区/ TxP的配置。在某些方面，CSI-RS组的新概念，即UE认为一组用于预编码矩阵指示符（PMI）/信道质量指示符（CQI）/秩指示符（RI）报告）的一组CSI-RS端口，可以被定义。

摘要： Systems, apparatuses, and methods are disclosed for a relay station (120) for use in a communication system with a base station (eNB) and user equipment (UE). The relay station may decode and forward a data packet between the base station and the UE that the relay station services in which the relay station does not establish a direct link with the UE. Further, the relay station indicates successful decoding of the data packet to the base station such that if the base station receives information indicating successful decoding of the data packet from the relay station, the base station terminates a HARQ transmission on a direct link between the base station and the UE such that HARQ retransmission time is extended compared to direct communications between the base station and the UE.

摘要： Techniques for sending control information are described. In an aspect, information to send in a control message may be fragmented into multiple parts, with each part including information of a particular type. The multiple parts may be segregated into multiple categories such as dynamic, semi-static, and static. A full message containing all parts may be generated and sent at a first rate. A first partial message containing parts in the dynamic category may be generated and sent at a highest rate. A second partial message containing parts in the semi-static category may be generated and sent at a second rate that is slower than the highest rate. A third partial message containing parts in the static category may be generated and sent at a third rate that is slower than the second rate.

摘要： System(s) and method(s) that facilitate assignment mismatch recovery are provided. A projected level of resources required to satisfy one or more communication constraints (e.g., inter-cell and intra-cell interference) is generated. The projected resources are contrasted with scheduled resources and a determination is made as to whether a mismatch between assigned and projected resources exists. A mismatch is recovered through an adaptive response that feeds back magnitudes for the communication resources which are compatible with the communication constraints.

摘要： Systems and methodologies are described that facilitate soft handoff and enhanced performance in a wireless communication environment. In multiple access systems, access points assign certain resources (e.g., time, frequency, code) to each terminal. This assignment information can also be provided to neighboring sectors, allowing such sectors to receive and decode terminal transmissions. The information can be provided via backhaul signaling. Decoding by sectors within the active set of the terminal facilitates smooth transition as terminals move between sectors during soft handoff. In addition, sectors can signal successful receipt and decoding of transmissions, avoiding redundant processing.
