Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying, while the UE is in a connected mode with a network, a radio resource configuration of the UE, selecting a dedicated set of resources for the UE or a common set of resources for a plurality of UEs based at least in part on the identified radio resource configuration, and transmitting a pilot signal to the network using the selected set of resources. Methods for wireless communication at a network access device and a network access device controller are also described.

Systems and methods are provided for reducing communications between servers and a mobile device and providing enhanced security and privacy to wireless beacon services. This can involve a broadcast device transmitting a beacon transmission using a short range wireless radio, such a Bluetooth or WiFi, and including a MAC address, a first unique identifier, and a beacon service identifier. The mobile device then selects one or more unique identifiers from received beacon transmissions, by filtering (that is, selecting) those beacon transmissions which include the beacon service identifier. The wireless device then takes further action, if the first unique identifier is present among the selected one or more unique identifiers, using stored information from the server. The stored information may be delivered to the wireless device in response to the wireless device sending the first unique identifier to a server, or the stored information may have been previously downloaded.

According to an example embodiment, a method may include receiving, by a user equipment from a serving base station associated with a source cell, a reconfiguration message that includes a target cell configuration for a target cell, a configuration of a conditional handover execution condition, and information that indicates that the user equipment should immediately decode and apply the target cell configuration upon receiving the reconfiguration message; and immediately decoding and applying, by the user equipment, the target cell configuration upon receiving the reconfiguration message, without waiting for the conditional handover execution condition to be fulfilled.

The present disclosure relates to performing communication after mobility wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving, from a network, a measurement configuration comprising a measurement identity (ID); receiving, from a network, a conditional mobility command for a target cell, wherein the conditional mobility command comprises a mobility condition for the target cell, and the mobility condition for the target cell is related to the measurement ID; performing a mobility to the target cell based on the conditional mobility command for the target cell; and removing the measurement ID after performing the mobility to the target cell.

A method performed by a master node (MN) serving a wireless device with a secondary node (SN) in dual connectivity (DC) in a wireless communication system, the method including: transmitting, to the wireless device, a conditional primary serving cell (PSCell) mobility command for a first cell in the SN; transmitting, to the SN, a message requesting a modification of the conditional PSCell mobility command for the first cell, the message including an identity (ID) of the wireless device, a target cell ID of the first cell for which the conditional PSCell mobility is to be modified, and an indication to modify the conditional PSCell mobility command for the first cell; receiving, from the SN, an acknowledgement (ACK) message for modification of the conditional PSCell mobility command for the first cell; and transmitting, to the wireless device, information related to modification of the conditional PSCell mobility command for the first cell.

Passive collection of neighbor base station configuration information through handover messages is provided. In one embodiment, a base station comprises: a processor coupled to a memory, the base station coupled to a core network for a wireless network operator, the base station radiates downlink RF signals to at least one UE and receives uplink RF signals from the UE. The processor implements: a UE handover function that receives and processes a handover request message associated with a UE transferring to the cell from a neighboring cell; and a handover request parser that evaluates information elements in the handover request message to extract neighbor information. The handover request parser stores the extracted neighbor information as a set of neighbor information in the memory; and wherein the processor is configured to adjust operation of the base station based on the set of neighbor information stored in the memory.

A method of operating a mobile communication system of a motor vehicle is provided for initiating a voice call with a third party. The system includes an ECU, and the ECU includes a controller and a memory storing computer code. The method includes the steps of: (a) initiating a timer; (b) operating the ECU in a first mode in which the ECU attempts to engage in a VoNR call via a first network; (c) repeating step (b) within a predetermined amount of time until the ECU successfully engages in the VoNR call; and (d) operating the ECU in a second mode to attempt to engage in a VoLTE call via a second network in response to the controller determining that the ECU in the first mode did not successfully engage in the VoNR call within a predetermined amount of time.

Cell handover method and apparatus, RRC reestablishment method and apparatus, medium and UE are provided. The cell handover method includes: receiving conditional handover command information from a base station, wherein the conditional handover command information includes a handover trigger condition, selecting a target cell from a plurality of candidate target cells that satisfy the handover trigger condition based on priority information, wherein the priority information includes priority levels of the plurality of candidate target cells; and performing a cell handover operation from a current serving cell to the target cell. The RRC reestablishment method includes: if RRC reestablishment is triggered, performing cell selection, and determining a target access cell from a plurality of cells searched in the cell selection based on priority information, and performing the RRC reestablishment in the target access cell, wherein the priority information includes priority levels of the plurality of cells used for conditional handover.

A central unit (CU) of a distributed base station for configuring a dual active protocol stack (DAPS) procedure at a UE communicating with the distributed base station via a source distributed unit (DU) (i) determines (1002) that the UE is to perform the DAPS procedure in order to disconnect from the source DU and connect to a target DU; and (ii) transmits (1008), to the source DU, an indication that the source DU is to continue communicating with the UE during the DAPS procedure.
