Abstract: Apparatus and methods for time division multiplexing of radio frequency channels in unlicensed radio frequency bands by a wireless device in communication with a cellular wireless network are disclosed. The wireless device obtains, from an eNodeB, a configuration for carrier aggregation using a primary component carrier (PCC) in a licensed radio frequency band and at least one secondary component carrier (SCC) in an unlicensed radio frequency band. The configuration information specifies an “on” time period and an “off” time period for a repetitive time division cycle to use the at least one SCC in the unlicensed radio frequency band. During an “on” time period, the wireless device can transmit or receive using the PCC and the at least one SCC, as scheduled by the eNodeB. During an “off” time period, the wireless device can transmit or receive using the PCC and not using the at least one SCC.

Abstract: 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.

Abstract: Techniques are disclosed relating to informing a network that a UE desires packet-switched voice communication. In one embodiment, a method includes receiving first information from a UE device requesting voice communication over a packet-switched network. In this embodiment, the method further includes transmitting, in response to the first information, second information to a base station serving the UE device, wherein the second information indicates that the UE device is requesting voice communication over the packet-switched network. In this embodiment, the transmitting is performed prior to establishment of a dedicated bearer by the base station for the UE device. In this embodiment, the second information operates to configure communications between the base station and the UE device to provide a particular quality of service for the packet-switched voice communication using the dedicated bearer.

Abstract: Performing a circuit-switched fallback (CSFB) call with improved reliability. A request to establish a CSFB call may be received by a UE that is currently in a pool overlap area. The network resource controller, or the base station, 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.

Abstract: Mobile devices, base stations, and/or relay stations may implement CSFB (circuit switched fallback) operations by using RRC (radio resource control) connection release and/or handover procedures. If the CSFB RAT (radio access technology) target is not well configured, the UE may be informed and provisioned by the NW during a CSFB procedure with the information to return to LTE. Having this information, the UE may perform an autonomous search of LTE cells after the CSFB call release, speeding up return to LTE. To minimize potential call failures during CSFB, the UE may autonomously perform an additional cell search, in particular a search for cells on a RAT different from the initial target RAT. This creates an opportunity to prevent call failure of CSFB calls that would otherwise fail. The UE may be provisioned during the CSFB procedure with information to perform the additional cell search, should such a search be necessary.

Abstract translation: 移动设备，基站和/或中继站可以通过使用RRC（无线电资源控制）连接释放和/或切换过程来实现CSFB（电路交换回退）操作。 如果CSFB RAT（无线电接入技术）目标没有被很好地配置，则在CSFB过程期间可以通过NW向UE通知和提供UE返回到LTE的信息。 具有这种信息，UE可以在CSFB呼叫释放之后执行LTE小区的自主搜索，加速返回到LTE。 为了最小化CSFB期间的潜在呼叫失败，UE可以自主地执行附加小区搜索，特别是搜索与初始目标RAT不同的RAT上的小区。 这将创造一个机会来防止否则会失败的CSFB呼叫的呼叫失败。 如果需要这样的搜索，则可以在CSFB过程期间为UE提供执行附加小区搜索的信息。

Abstract: 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.

Abstract: This disclosure relates to using a wake up signal in conjunction with cellular communication in unlicensed spectrum. A cellular base station may provide a wake up signal on an unlicensed frequency channel after successful completion of a listen-before-talk procedure. The wake up signal may include a preamble configured for coherent detection, and information indicating channel occupancy time for a cellular communication by the cellular base station and a cell identifier for the cellular base station. A wireless device may monitor the unlicensed frequency channel for a wake up signal, and may determine whether to monitor the unlicensed frequency channel for control channel signaling based on whether a wake up signal is received, and potentially also based on the contents of the wake up signal if a wake up signal is received.

Abstract: A circuit component may determine whether first signal indicative of at least one of the plurality of communication interface circuits accessing the FEM during a respective communication slot associated with the FEM has been received, determine a first Received Signal Strength Indicator (RSSI) value for the respective communication slot used by the FEM based on data associated with the respective communication slot, and store the first RSSI value in response to the first signal not being received. The circuit component may then determine a first gain for a subsequent slot based on the first RSSI value and discard the first RSSI value in response to the first signal being received.
