摘要： According to certain aspects, techniques for aperiodically reporting channel state information (CSI) on protected and unprotected resources are provided. The protected resources may include resources in which transmissions in a first cell are protected by restricting transmissions in a second cell. According to certain aspects, a request for channel quality indicator (CQI) may be sent in a first subframe, CQI may be measured for a second subframe having a first offset from the first subframe, and a corresponding CQI report sent in a third subframe having a second offset from the first subframe.

摘要： Techniques are provided for frequency spectrum sharing that allows secondary operators to access a frequency band of a primary operator without interfering with the primary operator's use of the band, while ensuring service continuity for devices of the secondary operators. For example, there is provided a method that may involve identifying an outage on a first channel of a plurality of channels of a spectrum, wherein each of the plurality of channels is allocated to one of a plurality of operators. The method may involve migrating all mobile stations in communication over the first channel of the plurality of channels to at least one other channel of the plurality of channels during the outage.

摘要： Methods and apparatuses are provided that include determining resources over which to measure signals from a base station. One or more parameters related to a resource restriction pattern can be provided to the device for measuring signals over indicated resources. The resource restricted pattern can correspond to a bitmap where each bit relates to a time period over which signals can be transmitted by the base station, and the bit can specify whether a signal received over the resource should be measured. The resource restriction pattern can correspond to a set or protected resources negotiated using a resource partitioning scheme.

摘要： There lies a challenge to develop a technique of accurately and efficiently determining an available communication channel. In accordance with some embodiments disclosed herein, techniques for sensing a primary user of a particular communication channel are performed more efficiently. In some implementations, a geo-location of a communication device is combined with a sensing algorithm in order to more efficiently perform spectrum sensing. In some implementations, a geo-location and an accuracy determination may be used to determine all required sample regions in order to ensure that a primary user is not present in a particular location.

摘要： Time division multiplexing (TDM) partitioning is one of the inter-cell interference coordination (ICIC) mechanisms considered for a heterogeneous network (HetNet) ICIC in a co-channel deployment. For example, in subframes that are pre-allocated to an evolved Node B (eNB), neighbor eNBs may not transmit, hence interference experienced by served user equipments (UEs) may be reduced. Semi-persistent scheduling (SPS) grants may have various available periodicities, which may not be compatible with TDM partitioning. Therefore, a UE may miss an SPS opportunity that was scheduled for a subframe that was not usable by the UE. Hence, using SPS grants with small periodicities in a heterogeneous network with TDM partitioning may require changes which may include adjusting the periodicities of the SPS grants, rescheduling of uplink SPS messages based on resource partitioning information (RPI), and/or determining RPI based on current SPS grants.
摘要翻译：时分复用（TDM）分区是在同频道部署中为异构网络（HetNet）ICIC考虑的小区间干扰协调（ICIC）机制之一。例如，在预分配给演进节点B（eNB）的子帧中，相邻eNB可能不发送，因此可能减少被服务用户设备（UE）经历的干扰。半静态调度（SPS）授权可能具有各种可用的周期性，这可能与TDM分区不兼容。因此，UE可能错过针对UE不可用的子帧调度的SPS机会。因此，在具有TDM分割的异构网络中使用具有小周期的SPS许可可能需要改变，其可以包括调整SPS授权的周期性，基于资源划分信息（RPI）重新安排上行SPS消息，和/或基于当前SPS赠款。

摘要： Techniques for establishing and maintaining peer-to-peer (P2P) communication are described. In an aspect, P2P communication on an unlicensed spectrum may be established and maintained with network assistance. In one design, a user equipment (UE) may communicate with a wide area network (WAN) to establish P2P communication with at least one other UE on a first frequency band that is not licensed to the WAN. For example, the UE may receive an assignment of at least one frequency channel in the first frequency band for P2P communication. The UE may then communicate peer-to-peer with the other UE(s) on the at least one frequency channel. The UE may also communicate with the WAN to maintain P2P communication with the other UE(s), e.g., to switch to another frequency channel if necessary.
