Abstract:
Wireless communication at a user equipment (UE) is described. In some cases, a UE may determine that a voice call is about to be setup or in the process of being setup with a cell that supports voice calls. While the voice call is pending, the UE may be motivated to connect to a cell that does not support voice calls. The UE may recognize that the cell does not support voice calls and refrain from connecting to the cell until after the voice call setup, and/or the voice call itself, has completed.
Abstract:
A method and apparatus for radio resource control (RRC) state transitions of a user equipment (UE) are provided. For the RRC state transitions of the UE, for example, a reconfiguration message is received at the UE while the UE is in a cell dedicated channel (CELL_DCH) state of the RRC states. The reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of RRC states. A plurality of acknowledgement procedures is sent on an uplink to the network, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state to the non-dedicated channel state.
Abstract:
Aspects of the disclosure provide for a method of efficiently implementing security configurations for multiple domains between a network entity and a UE in a wireless system. For instance, this disclosure provides for a network entity sending to a UE a first security mode command for a first domain, receiving a first security mode complete message in response to the first security mode command, and sending a second security mode command for a second domain. In an aspect, the second security mode command is sent in response to receiving the first security mode complete message. In an aspect, the UE does not receive a RLC acknowledgement. In another aspect, the UE saves the second security mode command until it receives the RLC acknowledgement. In an aspect, the network entity sends the second security mode command in response to receiving a message protected with first security procedure parameters.
Abstract:
The disclosure provides for a UE handling messages in wireless communication. The disclosure provides for a UE partially exchanging a first signaling-related message associated with a first UE configuration with a network entity and triggering a state transition message that initiates a change to a second UE configuration different from the first UE configuration. In an aspect, the UE determines that the first message has not been successfully received or successfully transmitted. In an aspect, the UE sends an indication message to coordinate discarding of the first message with the network entity and receives, after sending the indication message, a second signaling-related message associated with the second UE configuration. In another aspect, the UE, after partially sending a signaling-related message, receives a reconfiguration request associated with a second UE configuration. In an aspect, the UE determines that the message has not been successfully transmitted and causes a reconfiguration failure.
Abstract:
Some aspects described herein relate to reducing a delay in the retransmission of undelivered capability information segments. For example, when transmitting capability information via multiple segments, a UE may request the network to acknowledge each segment and/or may modify a network configured parameter to reduce the delay in retransmitting undelivered segments. In some aspects, a UE may attach to a network for a priority service, such as an emergency service or a short message service. In connection with the attachment, the UE may provide a reduced set of capability information that is relevant to the priority service and that omits at least some capability information irrelevant to the priority service.
Abstract:
Methods, systems, and devices for wireless communications are described. A network entity may support communications with a user equipment (UE) that is moving at a first speed that meets or exceeds a threshold via a cell that is configured to support such communications, which may be referred to as a high speed train (HST) cell. The network entity and the UE may support cell acquisition that prioritizes camping on an HST cell over a non-HST cell. The UE and the network entity may communicate acquisition signaling associated with establishing a connection with the network entity using a first frequency associated with an HST cell and a non-HST cell. Based on an identifier indicating that the HST cell is an HST cell, the UE may prioritize the HST cell over the non-HST cell during cell acquisition and establish the connection with the network entity via the HST cell.
Abstract:
A method of wireless communication by a user equipment (UE) includes receiving, from a network, a capability request including a frequency band filter. The method further includes retrieving, from a server, a prioritized list of frequency band combinations based on a location of the UE. The method still further includes transmitting, to the network, the prioritized list adjusted based on the frequency band filter, in response to the capability request. A method of wireless communication by a network device includes receiving, from a UE, a request for a list of frequency band combinations based on a location of the UE. The method further includes transmitting, to the UE, a prioritized list of frequency band combinations for the location of the UE. The prioritized list is based on a selected network configured frequency band combination associated with the location of the UE.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to a connected state. The UE may configure, based at least in part on receiving the RRC resume message, the UE with a serving cell common configuration, associated with a serving cell of the UE, received in a system information block (SIB) associated with the serving cell. Numerous other aspects are provided.
Abstract:
This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing communications with a base station by a processor of a wireless device. In one aspect, a processor of a wireless device may receive from the base station a system information change indication in first system information. The processor may determine from the first system information scheduling information of second system information. The processor may determine a factor that a request for the second system information will collide with a request from another wireless device for the second system information. The processor may send the request for the second system information using the determined factor.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication and techniques to prevent frequent beam switching. In some aspects, a user equipment (UE) may determine a duration of time that the UE dwells on a beam. The UE may update a data structure, stored in memory of the UE, to add or modify a stored duration value associated with the beam based at least in part on determining the duration of time that the UE dwells on the beam. The UE may determine that a condition associated with the stored duration value is satisfied. The UE may modify a priority of the beam in connection with a beam selection procedure based at least in part on determining that the condition associated with the stored duration value is satisfied. Numerous other aspects are provided.
