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: Apparatus and methods to improve compatibility between a primary wireless device including multiple subscriber identity modules (SIMs) and a cellular capable secondary wireless device are disclosed. The cellular capable secondary wireless device pairs with the primary wireless device, which provides a configurable option to allow mobile terminated connections and/or messages to be received at the cellular capable secondary wireless device for multiple SIMs when the cellular capable secondary wireless device is not within proximity of the primary wireless device and is being worn. The primary wireless device indicates conditional forwarding to a second wireless network associated with a second SIM and adjusts notification alerts to reduce time for forwarding when the cellular capable secondary wireless device is separated from the primary wireless device and in use.

Abstract: Various radio resource management techniques may be implemented to reduce in-device coexistence issues and/or interference between a Uu link established between a mobile device (first UE) and a base station (first NB), and a sidelink/PC5 link established between the first UE and another mobile device (second UE), where the second UE is served by a different base station (second NB). The first UE may receive, from the first NB, measurement configuration information that enables/configures the first UE to report to the NB any indication(s) of issues caused by communications between the first UE and the second UE over the PC5 link affecting communications between the first UE and the first NB over the Uu link, and/or communications over the Uu link affecting communications over the PC5 link. The first NB may analyze the feedback from the first UE and may implement mitigation measures to reduce/eliminate any interference and/or in-device-coexistence issues.

Abstract: This disclosure relates to techniques for efficiently handling connection rejections. A wireless device may detect barring conditions in response to receiving one or more connection rejections. The wireless device may bar one or more connections based on the barring conditions, and may attempt to access network services over one or more other connections.

Abstract: This disclosure relates to techniques for handling voice and data under uplink limited conditions in a wireless communication system. A wireless device and a base station may establish a wireless communication link. Transmission time interval bundling (TTI-B) may be enabled for uplink communications between the wireless device and the base station. It may be determined that the wireless device is experiencing uplink limited conditions. One or more rules prioritizing a first type of data over a second type of data for uplink communications may be enabled based on TTI-B being enabled and the wireless device experiencing uplink limited conditions.

Abstract: Generating and using a device-type specific preferred public land mobile network (PLMN) list for roaming PLMN selection. Wireless devices sharing one or more common characteristics may be tasked with collecting roaming PLMN selection data. That data may be collected and used to generate a preferred PLMN list specific to wireless devices sharing those common characteristics. The preferred PLMN list may be distributed to wireless devices sharing those common characteristics, which may then use it in conjunction with roaming PLMN selection.

Abstract: A wireless communication system is presented in which user equipment (UE) performs non-intra-frequency (NIF) cell reselection. The NIF cell reselection process can: detect, on a discontinues reception (DRX) cycle, whether a NIF for a second cell has passed a second reselection threshold; perform, on the DRX cycle, additional checks or measurements to determine whether a higher priority NIF for a third cell has passed a third reselection threshold; and continue a cell reselection process for the second cell and the third cell. The NIF cell reselection techniques can help ensure that the UE reselects to higher priority cells without expending an unnecessary amount power.

Abstract: Performing cell re-selection by a device. A first cell on which to camp may be selected. The device may camp on the first cell in an idle-mode. The device may be configured to perform searches for neighboring cells according to an idle-mode timeline while camping on the first cell. The device may transmit a connection request to the first cell in order to transition the device from the idle-mode to a connected-mode via the first cell. One or more searches for neighboring cells may be performed according to a connected-mode timeline after transmitting the connection request, in response to transmitting the connection request. The one or more searches may be performed before the device establishes the connected-mode with the first cell.
