Abstract: This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A remote wireless device may transmit a radio resource control message that includes information configured to be relayed to a cellular base station to a relay wireless device, which may relay the information to the cellular base station. The cellular base station may also transmit a radio resource control message that includes information configured to be relayed to the remote wireless device to the relay wireless device, which may relay the information to the remote wireless device.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and a network to perform flexible acknowledgement. A UE may determine whether or not to solicit feedback (e.g., HARQ ACK/NACK) for one or more groupcast transmissions. The determination may be based on factors such as a remaining time to perform the transmission and the amount of time needed to perform the transmission with and without allowing time to receive and process feedback.

Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Abstract: This disclosure relates to providing in order packet delivery for compressed radio bearers. A wireless device may receive packet data at a packet data convergence protocol layer. A packet reordering timer length to use for the packet data at the packet data convergence protocol layer may be adaptively selected from multiple possible packet reordering timer lengths. The packet data may be processed at the packet data convergence protocol layer using the selected packet reordering timer length. The packet reordering timer length may be selected based at least in part on a robust header compression decompressor state of the packet data convergence protocol layer.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to communicate an RRC message (such as an RRC configuration message) having a size that exceeds PDCP SDU size constraints. According to some embodiments, a base station may generate a large RRC message, e.g., by encoding an RRC configuration as a single large RRC message. The base station may then segment the RRC message, e.g., at the RRC layer or the PDCP layer, into a series of PDUs that comply with the size constraints. According to some embodiments, the base station may encode an RRC configuration as a series of RRC messages, each complying with the size constraints. The base station may further provide an indication of when a receiving user equipment should apply the RRC configuration.

Abstract: Apparatuses, systems, and methods for a wireless device avoiding reselection or handover to cells of different operators. The wireless device may attach to a first base station of a first network operator. The wireless device may determine that a neighboring base station is associated with a second network operator. Based on determining the neighboring base station is associated with the second network operator, the wireless device may exclude the third base station from handover or reselection.

Abstract: Techniques and devices for service-specific tagging of data by an application processor (AP) of a user equipment device (UE). A first indication may be sent from the UE to a baseband processor (BB) of the UE of one or more quality of service preferences for an upcoming data session, and the BB may configure one or more layers of the BB according to the quality of service preferences. The BB may further communicate with a network to establish protocols for the quality of service preferences. The BB may determine one or more network conditions, and may transmit feedback from the BB to the AP related to the determined network conditions. In response, the AP may send a second indication of one or more updated quality of service preferences to the BB based at least in part on the feedback received from the BB.

Abstract: Apparatuses, systems, and methods for improving efficiency in IMS registration and management in a wireless communication device, such as a UE. In some scenarios, the UE may, while implementing IMS services (e.g. for VoLTE) over a wireless communication link with a cellular network, determine that the wireless communication link is not performing at an acceptable level. In response, the UE may start a timer and buffer IMS SIP signaling messages while the timer is running. If the wireless communication link performance is restored to an acceptable level before expiration of the timer, the UE may transmit the buffered IMS SIP signaling messages. If the timer expires prior to restoration of the wireless communication link, the buffered messages may be cleared, and the UE may locally deregister from IMS registration and IMS PDN. In some scenarios, select IMS SIP signaling messages may be omitted or removed from the buffer.
