Abstract: Techniques described herein may help conserve the power of user equipment devices (UEs) in a radio access network (RAN) that is implementing a communication policy involving flexible frame structures. A network device, such as a base station or wireless router, may monitor network traffic in the RAN and determine an appropriate frame structure based on the network traffic. The network device may convey the frame structure to UEs in the RAN so that the UEs know when an ongoing frame will transition from downlink (DL) subframes to uplink (UL) subframes. Doing so may alleviate a need for the UEs to continue monitoring the network for the actual transition from UL subframes to UL subframes, thereby conserving the power usage of the UEs.

Abstract translation: 这里描述的技术可以帮助保存正在实现涉及灵活帧结构的通信策略的无线电接入网络（RAN）中的用户设备装置（UE）的功率。 诸如基站或无线路由器之类的网络设备可以监视RAN中的网络业务并且基于网络业务来确定适当的帧结构。 网络设备可以将帧结构传送给RAN中的UE，使得UE知道正在进行的帧何时将从下行链路（DL）子帧转变到上行链路（UL）子帧。 这样做可以减轻对UE继续监视网络以寻求从UL子帧到UL子帧的实际转变的需要，从而节约UE的功率使用。

Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to enable the signaling of a discovery reference signal (DRS) over an unlicensed band. A scheduling component can process a downlink (DL) transmission comprising a DRS transmission window (DTxW) associated with the DRS, based on a set of predetermined criteria. The DL transmission can be transmitted or received with an unlicensed carrier over a physical broadcast channel (PBCH). The predetermined criteria can comprise a network cell specific identification of a network cell associated with the DTxW to enable an initial random access to the network cell by one or more UEs.

Abstract: In the context of License Assisted Access on a wireless network, LAA LTE, to unlicensed spectrum, uplink scheduling and reception at an evolved Node B, eNB, and contention access and transmission at a User euipment, UE, are described. the eNB schedules uplink resources consisting of multiple subframes. The UE performs Listen-Before-Talk, LBT, procedures before transmitting within the scheduled subframes. transmission puncturing is applied either before a subframe or at the end of a subframe. A first, second and third circuitry are described. The first circuitry may be operable to identify a first subframe being unavailable for a first Listen-Before-Talk (LBT) procedure within the unlicensed spectrum, in which the first LBT procedure determined the unlicensed spectrum to be busy. The second circuitry may be operable to perform a second LBT procedure in a second subframe subsequent to the first subframe. The third circuitry may be operable to generate an Uplink (UL) transmission over the unlicensed spectrum in the second subframe. The UE that acquires the uplink channel sends a reservation signal, for example, a demodulation reference signal, DM-RS.

Abstract: Devices and methods of transmitting on an unlicensed band are generally described. A UE determines that an unlicensed medium is idle using a LBT procedure and transmits a burst that ranges from a partial PUSCH to multiple PUSCHs that are aligned or asynchronistic with the PCell boundary. The burst can be scheduled by the eNB or autonomously scheduled by the UE. In the latter case, the UE indicates the presence of the burst in a preamble and aligns to the boundary. In the former case, an initial and ending PUSCH is generated that occupies a partial or super frame. Control information is provided in a UCI of a PUCCH, which is provided simultaneously with the PUSCHs or before start of the UL burst that spans one or more OFDM symbols.

Abstract: Systems, apparatus, user equipment (UE), evolved node B(eNB), computer readable media, and methods are described for license assisted access (LAA) communications on an unlicensed channel. The eNB determines if a subframe to be transmitted is a partial subframe, and if the subframe is not a partial subframe, constructs the subframe to contain both a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) at fixed symbol positions within the subframe. In further embodiments, the eNB determines if a last subframe of a downlink (DL) transmission burst to be transmitted is a partial subframe, and if the subframe is not a partial subframe, constructs the subframe to contain a discovery reference signal (DRS) for transmission.
