Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.

User equipment having multiple subscriber identity modules with improved suspend / resume operation

The present application relates to devices and components including apparatus, systems, and methods for concatenating in the packet data convergence protocol sublayer or the service data adaptation sublayer in wireless networks.

Communication devices and methods for concatenating service data units

The present application relates to devices and components including apparatus, systems, and methods for user equipments and network components performing or assisting in packet filtering operations.

Technologies for packet filtering for protocol data unit sessions

Techniques discussed herein can facilitate inactive state transmissions for a Base Station (BS) via a 4-step or 2-step inactive state RACH process. One example aspect is a BS including communication circuitry and one or more processors communicatively coupled to the communication circuitry and configured to cause the BS to transmit a radio link quality threshold and an uplink data size for a Radio Resource Control (RRC) inactive data transmission. Receive a Random Access Channel (RACH) preamble in response to the radio link quality threshold and the uplink data size being satisfied. Receive the RRC inactive data transmission, and transmit a RACH message in response to receiving the RRC inactive data transmission.

Systems and methods for providing random access channel (RACH) signaling to user equipment (UE) during inactive direct transmissions

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 sends, by the first SIM, a first registration request to the network, wherein the first registration request comprises an identification indicating the multi-SIM device is a type of multi-SIM device, receives, by the first SIM, a first registration accept message indicating the first registration request has been accepted, wherein the first registration accept message comprises a first temporary identification for the first SIM and sends, by the second SIM, an access network message comprising one of the first temporary identification or a further temporary identification based on, at least, the first temporary identification.

Control plane for multi-SIM devices

A remote user equipment (UE) configured to access a network via one of a direct link with a base station or a relay link with a relay UE performs a method including receiving link selection criteria, the link selection criteria configured by the network, identifying that the relay UE is available for camping, selecting the relay UE based on the link selection criteria, camping on the relay link corresponding to the relay UE and initiating a network access procedure via the relay link.

Link selection for an idle or inactive user equipment

A method and apparatus of a device that communicates data between a user equipment (UE) device and a base station when the user equipment is in the inactive state is described. In some embodiments, the last serving base station of the UE and the new base station of the UE coordinate with each other to complete the transfer of data while the UE is in the inactive state.

Context fetch procedure for inactive direct data transmission

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.

Radio resource control connection procedures for remote wireless devices

A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Transmitting wake-up signals for paging operations

A base station may operate in a context where the propagation delay between the base station and user equipment (UE) devices is large. The base station configures UE devices with a common delay. The base station receives a random access preamble from a UE device. The base station determines a time slot in which the random access preamble was transmitted, based on a configured correspondence between allowable time slots and subsets of an available set of preambles. The base station computes a Random Access Radio Network Temporary Identifier (RA-RNTI) based on parameter values including an index, of the determined time slot. The base station employs the computed RA-RNTI to address a random access response for the UE device.

Resolution of mismatch in calculation of random access radio network temporary identifier

A client device in a wireless network accesses a queue comprising Transmission Control Protocol Acknowledgement (TCP ACK) packets. At least some packets include packet descriptors with a flow identifier indicating a corresponding TCP flow, and a TCP ACK Generation Count. The device inspects a packet descriptor of a first TCP ACK packet, and identifies a first flow identifier and a first TCP ACK Generation Count. The device accesses entries in a data structure that each includes a first field and a second field respectively storing a flow identifier and a TCP ACK Generation Count. The device determines that a condition is satisfied, comprising that an entry in the data structure includes a flow identifier and a TCP ACK Generation Count matching the first flow identifier and the first TCP ACK Generation Count, respectively. In response to the determination, the device marks the first TCP ACK packet to be dropped.

Systems and methods for managing transmission control protocol (TCP) acknowledgements

A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

Traffic-rate based branch deactivation for UE power efficiency in a dual-connectivity mode

A base station associated with a wireless communication system is disclosed. The base station comprises one or more processors configured to generate a service configuration signal to be provided to a user equipment (UE) associated therewith. In some embodiments, the service configuration signal comprises an indication of one or more service configurations associated with a data transmission that are allowed to be transmitted by the UE during an INACTIVE state of the UE. In some embodiments, the one or more processors is further configured to provide the service configuration signal to the UE.
