摘要： This disclosure relates to performing cellular communication in unlicensed spectrum using a flexible slot structure. A cellular base station may perform a listen-before-talk procedure, and may transmit a reservation frame when the listen-before-talk procedure is successful. The reservation frame may reserve a wireless medium for a transmit opportunity. Transmission slots may be scheduled for communication with one or more wireless devices during the transmit opportunity. The transmission slots may be selected from multiple possible uplink transmission slot types and multiple possible downlink transmission slot types. Indications of the scheduled transmission slots, including indications of slot types of the scheduled transmission slots, may be provided to the wireless devices. Wireless communication may be performed between the cellular base station and the wireless devices according to the scheduled transmission slots.

摘要： A wireless device, such as a user equipment device (UE), and a base station are disclosed, which may communicate with more efficient use of dynamic transmit time interval durations to enable a faster and more efficient ramp up of TCP communications to a higher or maximum throughput. The UE may communicate uplink or downlink communications with the base station according to a first shorter TTI duration for a first period of time. After the first period of time, the UE may communicate uplink or downlink communications to the base station according to a second longer TTI duration. For the case of uplink communications, the UE may be configured to increase a congestion window size after each acknowledgement of an uplink communication received by the base station during the first period of time. For the case of downlink communications, the base station may be configured to increase a congestion window size after each acknowledgement of a downlink communication received by the UE during the first period of time.

摘要： Performing a circuit-switched fallback, CSFB, call with improved reliability. A request to establish a CSFB call may be received by a UE (106) that is currently in a pool overlap area. The network resource controller (172), or the base station (102), transmits information to the UE which indicates the pools in which neighboring cells are operating. The UE uses this information to select a circuit-switched cell on which to operate for the CSFB operation, wherein the selected CS cell is in the same pool area as the current pool area. This prevents the UE from inadvertently camping on a CS cell in a different pool area, which could cause call failure on some networks. The information provided by the base station may comprise a pool area id, or may comprise mapping relation information that is useable by the UE to determine the current pool area.
摘要翻译：执行电路交换后备，CSFB，提高可靠性。建立CSFB呼叫的请求可以由当前在池重叠区域中的UE（106）接收。网络资源控制器（172）或基站（102）向UE发送指示相邻小区正在操作的池的信息。 UE使用该信息来选择其上用于CSFB操作的电路交换小区，其中所选择的CS小区与当前池区域在同一池区域中。这样可以防止UE在不同池区域的CS小区上无意中驻留，这可能导致某些网络的呼叫失败。由基站提供的信息可以包括池区域id，或者可以包括可用于UE来确定当前池区域的映射关系信息。

摘要： Mobile devices, base stations, and/or relay stations may implement methods for decreasing required guard bands while also minimizing Adjacent Channel Leakage Ratio, when multiple mobile devices communicate over different respective adjacent specified frequency bands. For communications over at least one specified frequency band of the different respective adjacent frequency bands, a first bandwidth of uplink communications and/or a second bandwidth of downlink communications may be adjusted to differ from each other, and/or a communications bandwidth within the specified frequency band may be adjusted to be of a first size during a first portion of a specified data transmission period and to be of a second size during a second portion of the specified data transmission period, when at least some of the communications over the specified frequency band take place at frequencies adjacent to frequencies at which at least some of the communications take place over another specified frequency band.

摘要： This disclosure relates to using a dedicated reference subframes in a cellular communication system. According to one embodiment, a base station may transmit reference signals in a dedicated synchronization and measurement reference subframe. Neighboring base stations may also transmit reference signals in dedicated reference subframes in a temporally coordinated (synchronized) manner. The reference signals transmitted be each base station may be orthogonal with the reference signals transmitted by each neighboring base station. The reference subframes may be transmitted periodically, and data subframes may be transmitted between reference subframes. Some or all of the data subframes may not include cell-specific reference symbols, as their function may be unnecessary given the use of the dedicated reference subframes.

摘要： This disclosure relates to aggregation of radio resources provided according to multiple radio interfaces. According to some embodiments, a base station may establish a radio bearer with a wireless user equipment (UE) device. The radio bearer may initially utilize a first radio interface between the base station and the UE. The base station may receive an indication to aggregate radio resources of an access point that utilizes a second radio interface for the UE. Based on the indication to aggregate radio resources for the UE, the base station may redirect at least a portion of data of the radio bearer by way of the access point to be exchanged with the UE using the second radio interface.
