    Abstract: Techniques described herein include solutions for enabling user equipment (UEs) to report UE capability information based on deployed channel bandwidths (BWs) in each radio frequency (RF) band used by a base station. During an attached procedure, a base station may UE capability information from a UE and receive requested frequency band information (RFB) in response thereto. The RFB information (e.g., UE capability information) may be based on a comparison of an actual maximum BW for all possible CA combinations for the base station and Ω—a maximum aggregate BW supported by the UE. The UE may report the RFB to the base station for the CA combinations with a maximum BW that is less than or equal to Ω. After reporting, the UE may proceed with the attach procedure. Additional and alternative features and techniques are also described.

    Abstract: Apparatus and methods to access services of multiple wireless networks by a wireless device are disclosed. The wireless device attaches to a primary wireless network using a primary subscriber identity module (SIM) or electronic SIM (eSIM) via a radio access network (RAN) of the primary wireless network; establishes (i) a context for Internet Protocol (IP) network data connections using the primary SIM or eSIM and (ii) a packet data network (PDN) connection via the RAN of the primary wireless network to a gateway of a secondary wireless network using a secondary SIM or eSIM; and registers for access to services of the secondary wireless network with a server of the secondary wireless network using the secondary SIM or eSIM. The wireless device can access services of both the primary wireless network and the secondary wireless network simultaneously via the RAN of the primary wireless network.

    Abstract: In some embodiments, a wireless device such as a user equipment (UE) may communicate with a base station using an advanced form of carrier aggregation. The UE may provide signaling to the network specifying a number P of downlink component carriers to be configured for use by the UE for downlink carrier aggregation and a number Q of uplink component carriers to be configured for use by the UE for uplink carrier aggregation. The UE can only utilize a lesser number M of downlink component carriers at any given time in downlink carrier aggregation and can only utilize a lesser number N of uplink component carriers at any given time in uplink carrier aggregation. Thus the UE may request the network to configure a greater number P and Q of downlink and uplink component carriers, respectively, than the UE can actually use at any instant of time.

    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: The techniques described herein include provide solutions to optimizing the battery power of a user equipment (UE) though energy optimal radio link adaption. A UE may determine an energy optimal modulation and coding scheme (MCS). An energy optimal MCS may include an MCS that enables reception of a data payload at a lowest total energy consumed by a receiver. In some implementations, the MCS may be based on several factors, including time and/or data rate constraints and changes in transfer rates relative to changes in energy consumption. The UE may communicate the energy optimal MCS to a base station, and the base station may send a data payload to the UE using an energy optimal data transfer rate that is based on the energy optimal MCS.
