Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

Abstract: A user equipment (UE) is grouped into a paging subgroup for the purposes of receiving pages from a network. The UE receives, from the network, a paging configuration for a Radio Resource Control (RRC) idle state or an RRC inactive state paging operation, the paging configuration comprising a paging subgroup identification for the UE and monitors paging occasions based on at least the paging subgroup identification.

Abstract: A user equipment (UE) is configured to communicate with a further UE via a sidelink (SL). The UE encodes traffic for transmission to the further UE, wherein the traffic comprises a payload and a medium access control (MAC) subheader, wherein the MAC subheader indicates whether the payload corresponds to non-routed traffic between the UE and the further UE or routed traffic between either one of the UE or the further UE and a base station, wherein an other one of the UE or the further UE functions as a relay for the routed traffic and transmits the traffic.

Abstract: A user equipment (UE) is configured to decode a system information block (SIB). The UE receives a first signal, wherein the first signal includes a first individual system information block (SIB) segment of a SIB, receives a second signal, wherein the second signal includes a second individual SIB segment of the SIB, reassembles the SIB using first SIB segment and the second SIB segment and decodes the contents of the SIB.

Abstract: The exemplary embodiments relate to a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. A user equipment (UE) enters into a first state including one of a non-dormant state or a dormant state with a secondary serving cell (SCell) of a network, the SCell being configured to provide either one of a non-dormant bandwidth part (BWP) as a secondary component carrier (SCC) in the non-dormant state or a dormant BWP as an SCC in the dormant state. The UE switches from the first state to a second state including the other one of the non-dormant state or the dormant state, the switch being based on network configuration, a dormancy timer, or a radio condition.

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 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.

Abstract: A device and method for a user equipment (UE) to implement power savings mechanisms when operating within a significant location. The UE identifies that the UE is at a significant location. The significant location is a location relative to a currently camped cell of a network. At a first time and at the significant location, the UE performs a type of operation related to the network connection. The UE stores information corresponding to the performance of the type of operation at the first time in a profile associated with the significant location. At a second time and at the significant location, the UE performs the type of operation related to the network connection. The performance of the type of operation at the second time is modified based on the information stored in the profile associated with the significant location.

Abstract: 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.

Abstract: The exemplary embodiments describe devices, systems and methods for implementing various exemplary techniques related to fifth generation (5G) new radio (NR) cell search. A user equipment (UE) selects a frequency band to scan during a cell search procedure and identifies a frequency within the frequency band that is associated with a synchronization signal block (SSB) based on an indication of the frequency stored locally at the UE prior to the cell search procedure. The UE then scans the frequency for the SSB and determines that the SSB has been broadcast by a cell over the frequency.
