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: Apparatuses, systems, and methods for a wireless device to perform master cell group failure recovery in a dual connectivity cellular communication system. The wireless device may establish a first wireless link to a cellular network via a first cell group. The first cell group may be configured as a master cell group for the wireless device. The wireless device may establish a second wireless link to the cellular network via a second cell group. The second cell group may be configured as a secondary cell group for the wireless device. The wireless device may determine that link failure for the first wireless link has occurred. The wireless device may perform master cell group link failure recovery using the second wireless link based at least in part on the link failure for the first wireless link.

Abstract: To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

Abstract: This disclosure relates to techniques for performing consecutive conditional handovers. A cellular base station may provide conditional handover information for multiple conditional handovers to a wireless device. The conditional handover information may include information for performing a conditional handover from a cell provided by the cellular base station to at least one cell, and information for performing a conditional handover from one or more of those cells to at least one cell. The wireless device may perform multiple consecutive conditional handovers using the conditional handover information.

Abstract: Apparatuses, systems, and methods for performing multi-TRP transmissions using techniques for reducing wireless device power consumption. A wireless device may select a downlink signal buffering method for a communication slot. The downlink signal buffering method may be selected from a single antenna panel signal buffering method or a multi-antenna panel signal buffering method. One or more beams for which to perform downlink signal buffering for the communication slot may be selected based at least in part on the downlink signal buffering method selected. Downlink signals may be received from one or more cellular base stations during the communication slot using the selected one or more beams. The downlink signals received using the selected one or more beams may be buffered by the wireless device.

Abstract: Apparatuses, systems, and methods for a wireless device to perform single transmitter dual connectivity cellular communication. The wireless device may establish a radio resource control connection with a base station. The wireless device may provide an indication of radio frequency capability information for the wireless device to the base station. Providing the radio frequency capability information for the wireless device may affect whether and how the wireless device is configured for dual connectivity cellular communication.

Abstract: 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 transmits a connection request message to a base station over a first network using the first SIM, where the connection request message includes one or more capability indications of the UE. The UE receives a connection accept message from the base station, where the connection accept message includes one or more network capability indications corresponding to respective UE capability indications of the one or more UE capability indications. The UE performs communications with the base station according to the one or more network capability indications.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to configure a UE for dual connectivity. In an example, a network node requests the UE to indicate the capability it supports for the dual connectivity. This request can implicitly or explicitly indicate that the UE should report carrier grouping information. In response, this information is sent by the UE, and the network node can configure an MCG and an SCG for the UE based on the reported carrier grouping information.
