Abstract: Techniques are described for wireless communication. One method includes winning a contention for access to an unlicensed radio frequency spectrum band, transmitting a request message upon winning the contention for access to the unlicensed radio frequency spectrum band, and receiving a response message over the unlicensed radio frequency spectrum band. The request message is transmitted by a user equipment (UE) on an enhanced physical random access channel (ePRACH) or shortened ePRACH (SePRACH), to access a cell that operates in the unlicensed radio frequency spectrum band. The response message is received in response to transmitting the request message, and the request message may be transmitted irrespective of whether a base station has gained access to the unlicensed radio frequency spectrum band.

Abstract: Methods, systems, and devices for wireless communication are described. A receiving device may detect a signal associated with low latency transmissions and decode a non-low latency communication accordingly. The receiving device may receive an indicator from a transmitting device that indicates where and when low latency communications occur. The indication may specify frequency resources or symbols used by the low latency communication. The indicator may be transmitted during the same subframe as the low latency communication, at the end of a subframe, or during a subsequent subframe. The receiving device may use the indicator to mitigate low latency interference, generate channel estimates, and reliably decode the non-low latency communication. In some cases, the interfering low latency communication may occur within the serving cell of the receiving device; or the interfering low latency communication may occur in a neighboring cell.

Abstract: UE-aided channel selection within unlicensed frequency bands. A base station may communicate with UEs using LTE/LTE-A carrier waveforms (e.g., configured as a secondary cell) in the unlicensed frequency band. The base station may configure UEs for wide-band interference feedback for channels in the unlicensed frequency band. The measurements of wide-band signal strength may be performed by the UEs on channels for which the base station is not currently transmitting, or during silent periods of a configured secondary cell. The UEs may feedback an average total received power over a measurement bandwidth for one or more frequency channels of the unlicensed frequency band. The base station may receive the wide-band signal strength feedback from the UEs and identify potential frequency channels for channel selection for the secondary cell based on its own measurements of the candidate channels, and the wide-band signal strength feedback from the UEs.

Abstract: Methods and apparatuses are provided that include mitigating interference for devices communicating with femto nodes or other low power base stations by assigning protected resources for communicating therewith. The protected resources can be negotiated with a macrocell base station using interference cancellation. The protected resources can be assigned based on an early or late handover event, which can indicate that the device may be susceptible to interference from the macrocell base station.

Abstract: Semi-connected state operation for UEs in multiple-access networks is described. In the semi-connected state, UEs may monitor system information and paging, and mobility may be UE-controlled. Base stations may determine whether to transition UEs from the connected state to the semi-connected state based on capabilities, priority, data connections, or loading conditions. Base stations may maintain context information and logical traffic connections for UEs while UEs continue to be served by the base station in the semi-connected state. Thus, when a transition from the semi-connected state to the connected state occurs, the base station does not have to re-establish security parameters, nor re-establish logical traffic connections within the network for carrying control plane and user plane data for the UE. Context information for semi-connected state UEs may be shared between neighboring base stations or base stations within a context area. The techniques may be applied to LTE/LTE-A networks.

Abstract translation: 描述了在多址网络中的UE的半连接状态操作。 在半连接状态下，UE可以监视系统信息和寻呼，移动性可以由UE控制。 基站可以基于能力，优先级，数据连接或加载条件来确定是否将UE从连接状态转换到半连接状态。 基站可以维护用于UE的上下文信息和逻辑业务连接，而UE在半连接状态下继续由基站服务。 因此，当从半连接状态到连接状态的转变发生时，基站不必重新建立安全参数，也不必在网络内重新建立用于承载控制平面和用户平面数据的逻辑业务连接 UE。 半连接状态UE的上下文信息可以在上下文区域内的相邻基站或基站之间共享。 这些技术可以应用于LTE / LTE-A网络。

Abstract: Updated media access control (MAC) operations for semi-persistent scheduling (SPS) and discontinuous reception (DRX) operations with enhanced component carrier (eCC) secondary cells (SCells) is disclosed. For SPS operations, an SPS operation is defined and monitored on the eCC SCell which is separate and independent from SPS operations on the primary cell (PCell). The eCC SCell SPS operation may be identified using either the network identifier for the PCell or a newly defined network identifier specifically for the eCC SCell SPS operation. For DRX operations, the DRX operations for the eCC SCell are defined with separate and independent timers from the DRX operations of the PCell.

Abstract: Techniques are described for wireless communication. A method for wireless communication may include identifying interference at a first node operating in a shared radio frequency spectrum band. The interference may be caused by a second node operating in the shared radio frequency spectrum band. The second node may operate asynchronously to the first node in the shared radio frequency spectrum band. The method may also include adaptively enabling, based at least in part on the identified interference, a synchronization of the first node with at least a third node in the shared radio frequency spectrum band.
