Abstract: Some aspects relate to apparatuses and methods for calculating an uplink pathloss in a wireless communication system. A user equipment (UE) can be configured to perform operations for calculating the uplink pathloss. The operations can include determining a transmission power of a physical uplink shared channel (PUSCH) transmission for a UE, TxpPUSCH, where the PUSCH transmission is from the UE to a base station. The operations can further include determining a receiving power of a sounding reference signal (SRS) by the base station, Rxpsrs; and further calculating the uplink pathloss based on the transmission power of the PUSCH transmission TxpPUSCH and the receiving power of the SRS Rxpsrs.

Abstract: A user equipment (UE) includes a first subscriber identification module (SIM) and a second SIM. The UE is configured to establish a first cellular network connection based on, at least, the first SIM and a second cellular network connection based on, at least, the second SIM. The UE detects a collision between i) multiple paging occasions or ii) multiple paging frames. The UE then initiates a procedure for updating a paging occasion for the first cellular network connection. The UE monitors for a page over the first cellular network connection during the paging occasion.

Abstract: A mobile device collects received information and processes it. In some instances, the mobile device detects, based on the collected information, that a base station is likely not legitimate, i.e., it is likely a fake base station, and the mobile device bars communication with the base station for a time. In some embodiments, the mobile device determines, based on the received information, that the base station is a genuine base station. When the mobile device determines that the base station is a genuine base station or the mobile device does not determine that it is likely the base station is a fake base station, the mobile device allows or continues communication with the base station.

Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A 5G-capable wireless device of an MNO, while connected to or camped on a legacy 4G LTE cell of the MNO and not engaged in a 4G only LTE service, determines whether an NSA 5G cell of another MNO satisfies performance criteria before measuring and/or sending measurement data for an NSA 4G LTE anchor cell associated with the NSA 5G cell to a wireless network. Refraining from measuring and/or sending measurement data under certain conditions causes the 5G-capable wireless device of the MNO to remain connected to or camped on the legacy 4G LTE cell of the MNO rather than reselecting or handing over to the NSA 4G LTE cell of another MNO. The 5G-capable wireless device also maintains a database of information for valid NSA 4G LTE cells to which to reselect/handover.

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station; and a processor communicatively coupled to the transceiver. The processor is configured to receive a sounding reference signal (SRS) resource configuration from the base station, wherein the SRS resource configuration indicates at least a first SRS resource and a second SRS resource. The processor is further configured to transmit a first SRS via the first SRS resource to the base station using a first antenna coupled to the transceiver and transmit a second SRS via the second SRS resource to the base station using a second antenna coupled to the transceiver. The processor is further configured to receive an SRS resource indicator (SRI) from the base station based on at least one of the transmission of the first SRS or the second SRS; select the first antenna based on the SRI indicating the first SRS resource; and transmit uplink data to the base station using the first antenna.

Abstract: Apparatus and methods to reuse wireless circuitry to communicate with multiple wireless networks to support multiple subscriber identities in a wireless communication device are disclosed. A representative method includes receiving signaling messages for a second subscriber identity from a second wireless network while connected to a first wireless network for a first subscriber identity. A portion of radio frequency wireless circuitry is reconfigured to communicate with the second wireless network to establish a signaling channel and respond to signaling messages received from the second wireless network. The portion of radio frequency wireless circuitry is reconfigured between the first and second wireless networks to maintain a connection with the first wireless network while also receiving from the second wireless network limited information that can be provided to a user. Representative information includes an indication of an originator of a mobile terminated connection request and short message service data.
