Abstract:
Certain aspects relate to methods and apparatus for wireless communications, comprising determining to use a reduced paging cycle to page a user equipment (UE) of a first type that supports the reduced paging cycle, the reduced paging cycle having a shorter period relative to a paging cycle used with UEs of a second type which do not support the reduced paging cycle, and paging the UE of the first type in accordance with the reduced paging cycle. Certain aspects relate to methods and apparatus for conveying system information by a base station, comprising broadcasting a first system information common to each cell of a group of cells in an area and broadcasting a second system information that can vary between cells in the group of cells, wherein the second system information is broadcast more frequently than the first system information.
Abstract:
Techniques for handover procedure management are described herein. An example method may include monitoring, at a target base station, reference signal information associated with a UE based on a reference signal configuration of the UE received by the target base station from a source base station. Additionally, the example method may include estimating, at the target base station, timing information for the UE based on the reference signal information. Further, the example method may include transmitting, by the target base station, the timing information to the source base station, where the source base station provides the timing information to the UE for handover to the target base station.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus serves data to a UE or receives data from the UE via a first communication link that uses a first RAT, transmits a configuration message to the UE indicating that data will be served or received via a second communication link that uses a second RAT, and initiates a configuration procedure to switch service or reception of data from the first communication link that uses the first RAT to the second communication link that uses the second RAT.
Abstract:
Methods and apparatus for switching bearers between radio access technologies (RATs) are described. According to aspects of the present disclosure, the uplink part of a bearer may be served by one RAT, while the downlink part of the bearer is served by another RAT. A part of a bearer may be served by more than one RAT. Methods and apparatus for communicating via bearer with parts served by differing RATs are also described.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive a message indicating that a user equipment (UE) has determined that a condition for a conditional primary secondary cell (PSCell) change has been satisfied for a candidate target PSCell. The candidate target PSCell may be one of a set of candidate target PSCells associated with the UE in a conditional PSCell change configuration provided by a base station. The MN may transmit, to a source secondary node, a confirmation message associated with the conditional PSCell change. Numerous other aspects are provided.
Abstract:
Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently collecting and reporting minimization of drive test (MDT) measurements for one or more radio access technology (RAT) types and/or for multiple base stations in a dual connectivity deployment. In one example, a user equipment (UE) may receive an MDT measurement configuration indicating a first RAT type for collecting measurements and a second RAT type for reporting measurements. In this example, the UE may use the measurement configuration to collect MDT measurements for the first RAT type, and the UE may report the MDT measurements to a base station associated with the second RAT. Further techniques for efficiently collecting and reporting MDT measurements in a dual connectivity deployment are also described herein.
Abstract:
Wireless communication devices, systems, and methods related to mechanisms to aid a user equipment (UE) in determining the channel access priority (CAPC) to use for a data radio bearer (DRB) on sidelink that includes multiple quality of service (QOS) flows for a transmission. The UE may receive an indication from a base station (BS) regarding what CAPC to use, or it may itself determine the CAPC based on a rule. The UE may map the plurality of QoS flows to the DRB and transmit the QoS flows using the DRB and the selected CAPC.
Abstract:
Methods, systems, and devices for wireless communications are described. In some examples, a first cell of a network entity may receive a first control message indicating a configuration associated with a user equipment (UE). Additionally, the first cell may identify a condition associated with transmitting a second control message indicating for the UE to perform a cell switch procedure. In some examples, the first cell may determine whether to forward the first control message to the UE based on the condition. In some other examples, the first cell may forward the first control message and transmit the second control message within the threshold duration of forwarding the first control message. In such cases, the UE may trigger the cell switch procedure based on receiving the second control message and may determine whether to apply the configuration associated with the first control message.
Abstract:
Wireless communications systems and methods related to communicating ACK/NACK feedbacks for multi-user and unicast physical down-link shared channel (PDSCH) communications are provided. A UE may receive a multi-user PDSCH communication including a first transport block (TB) for the UE and may receive a unicast PDSCH communication including a second TB for the UE. The UE may determine a hybrid automatic repeat request (HARQ) codebook for the first TB associated with the multi-user PDSCH communication and the second TB associated with the unicast PDSCH communication. The UE may transmit a first acknowledgement/negative-acknowledgment (ACK/NACK) feedback for the first TB and a second ACK/NACK feedback for the second TB based on the determined HARQ codebook.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a relay device associated with a serving cell, a discovery message including a system information block with an identifier associated with the serving cell. Accordingly, the UE may determine, using the identifier associated with the serving cell, a global identity associated with a base station of the serving cell. In some aspects, a UE may determine a radio resource control state associated with the UE. Accordingly, the UE may transmit, to a relay device, a paging configuration associated with the UE. Numerous other aspects are described.
