Abstract:
Aspects of the present disclosure relate to methods and apparatuses for wireless communication using a protocol data unit (PDU) including a service data adaptation protocol (SDAP) PDU that has an unciphered header. The unciphered SDAP header facilitates various optimizations in wireless communication.
Abstract:
A system and method of performing a handover include detecting an out of sync event while being connected to a current cell, determining whether a measurement report time-to-trigger signal is active, sending, in response to the detection of the out of sync even and the measurement report time-to-trigger signal being active, a first new measurement report and a first special cause flag prior to a next scheduled measurement report to the communication network, receiving a first list of one or more neighboring cells suitable for a handover, identifying a first neighboring cell from the first list for the handover, and attempting to perform the handover from the current cell to the first neighboring cell.
Abstract:
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a trigger condition relating to at least one of historical information stored by the UE, a user interaction with the UE, a mobility state of the UE, or an active or foreground application on the UE; and/or transmit a request for or proposal of a discontinuous reception (DRX) cycle length or configuration based at least in part on identifying the trigger condition, wherein the request for or proposal of the modified DRX cycle length identifies a positive or negative adjustment to the DRX cycle length. Numerous other aspects are provided.
Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for quality of service (QoS) configuration for wireless communications. Certain aspects provide a method for wireless communication by a base station. The method generally includes determining a channel quality for a user equipment communicating on a wireless channel. The method further includes selecting one or more values for the one or more parameters for providing QoS to the user equipment in a range of parameter values based on the determined channel quality.
Abstract:
Various aspects are described herein. In some aspects, the present disclosure provides a method for communicating in a wireless communication network. The method includes transmitting a message. The method further includes receiving a control protocol data unit (PDU) including a payload, the payload including an acknowledgement service data unit (SDU) of the transmitted message, in response to transmitting the message. The method further includes processing the control PDU at a lower layer based on a priority of the control PDU, wherein the priority of the control PDU is above a priority of data PDUs. The method further includes determining, based on the processing of the control PDU at the lower layer, that the payload of the control PDU includes an acknowledgement SDU. The method further includes forwarding the acknowledgement SDU to a higher layer, bypassing the lower layer. The method further includes processing the acknowledgment SDU at the higher layer.
Abstract:
Aspects of the present disclosure relate to performing a tune-away from a first radio access technology (RAT) to a second RAT. These techniques include, for example, a method in which one or more radio resources of a user equipment are tuned away from the first RAT (e.g., LTE technology) to the second RAT (e.g., legacy 2G/3G technology and/or Wi-Fi or Bluetooth technology). Based on detecting a need to tune away one or more radio resources, the UE may then determine a tune-away metric for each serving cell based on one or more performance impact factors associated with the serving cell being tuned away. The UE may select one or more of the cells to be tuned away based on the determined tune-away metrics. The UE may then tune one or more radio resources corresponding to the selected at least one cell away from the first RAT to the second RAT.
Abstract:
Certain aspects of the present disclosure provide methods and apparatus for implementing extended signaling in wireless communications. An example method generally includes generally includes receiving, from a base station, an indication of an ability to support communications using extended signaling not defined by a radio access technology (RAT) standard and a grant of resources sized to accommodate extended signaling from the UE, transmitting, to the base station, an indication that the UE supports communications with the base station using extended signaling, and communicating with the base station using extended signaling. Numerous other aspects are provided.
Abstract:
Aspects are disclosed for facilitating a hand-in to a femto cell. An identifier is assigned to a femto cell in which the identifier is based on a scrambling parameter and a timing parameter. A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified based on the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcast according to an offset related to the timing parameter. In yet another embodiment, a femto cell is detected during an active call. An identifier associated with the femto cell is then ascertained and reported.
Abstract:
Methods, systems, and devices for wireless communication are described. A network entity may configure a user equipment (UE) to report applicability information associated with artificial intelligence (AI) and/or machine learning (ML) functionalities and/or models. The applicability information indicates an applicability of a functionality and/or model per AI/ML-enabled feature or feature group. Based on the applicability information and a handover of the UE from a source network entity to a target network entity, the target network entity may configure a functionality and/or model. Additionally, or alternatively, the UE may be configured with a reference configuration and one or more additional configurations corresponding to respective AI/ML functionalities and/or models. The UE may apply an additional configuration based on a handover to the target network entity, the additional configuration satisfying an applicability condition, or both. Based on an indication of the applied configuration, one or more functionalities or models may be activated.
Abstract:
Disclosed are techniques for wireless positioning. In an aspect, a network node transmits, to a network entity, a request for transmission of one or more first positioning reference signals (PRS) resources having one or more physical layer security properties, and measures the one or more first PRS resources having the one or more physical layer security properties. In an aspect, a network entity receives, from a first network node, a request for transmission of one or more first positioning reference signals (PRS) resources having one or more physical layer security properties, and transmits, to a second network node, a request for the second network node to transmit the one or more first PRS resources having the one or more physical layer security properties to the first network node.
