Abstract:
Certain aspects relate to methods and apparatus for discovering whether one or more enhanced capabilities are supported by devices (e.g., user equipment (UE), base station (BS), etc.) in a network. The enhanced capabilities may include, for example, the ability to support certain low latency procedures, enhanced component carrier (eCC) capability, and the like. The devices in the network may perform one or more handover-related procedures (e.g., cell selection/reselection, make-before-break handover, etc.) and/or other procedures (e.g., QoS negotiation, etc.) based, at least in part, on support for the one or more enhanced capabilities.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first fractional amount of a first data flow to be served to a UE via a first communication link using a first radio access technology (RAT), determines a second fractional amount of the first data flow to be served to the UE via a second communication link using a second RAT, and serves the first fractional amount of the first data flow to the UE using the first communication link.
Abstract:
Certain aspects of the present disclosure relate to techniques for aggregating data from a wireless wide area network (WWAN) and wireless local area network (WLAN). In some aspects, a packet convergence entity (e.g., PDCP layer entity) communicates with first and second radio access technology (RAT) links. The packet convergence entity may determine from which of the first and second RAT links a data packet is received and may monitor a sequence number value of each of the received data packets. The packet convergence entity may perform one or more actions based on a determination that the data packets are received out of order. For example, the packet convergence entity may deliver the data packets to an upper layer entity as they are received (e.g., in order or out of order), may reorder the data packets and ignore data packet losses, and/or may request retransmissions of missing data packets.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (LAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second LAB donor CU. The IAB node may establish the first connection with the second parent DU. The LAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.
Abstract:
Methods, systems, and devices for wireless communications are described. A wireless device may establish a radio resource control (RRC) connection over a wireless local area network (WLAN) link. For example, the wireless device may transmit a packet to an access point or WLAN termination that includes an RRC container including an RRC message for establishing (e.g., setting up, resuming) a connection with a centralized unit (CU). In some examples, the wireless device may additionally or alternatively be configured with dual connectivity over a WLAN link, including the addition, modification, and release of nodes associated with different radio access technologies. In such cases, the CU may configure connectivity with the WLAN, where the CU may configure a port number for each radio bearer via an RRC message transmitted over a direct link with the wireless device (e.g., via a distributed unit) or via the WLAN link.
Abstract:
Aspects relate to communication via multiple network slice services. A user equipment may support multiple network slice services (e.g., defined sets of network services and/or resources). At some point in time, the user equipment may communicate using a first network slice service provided by a first radio network entity (e.g., a first distributed unit, a first cell, a first base station, etc.). In addition, at some point in time, the user equipment may elect to use a second network slice service. In the event the first radio network entity is not available for the second network slice service, the user equipment may switch to a second radio network entity (e.g., a second distributed unit, a second cell, a second base station, etc.) to communicate using the second network slice service.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect radio link failure (RLF) or handover failure. The UE may perform, based at least in part on the RLF or the handover failure, one or more of layer 1 or layer 2 triggered mobility (LTM) or conditional handover based at least in part on a prioritization of LTM and conditional handover during failure recovery. Numerous other aspects are described.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a first scheduling request (SR) configuration associated with beam failure recovery (BFR) and a second SR configuration associated with BFR. The UE may detect a first beam failure associated with a first communication node. The UE may transmit a first SR on a first SR resource indicated by the first SR configuration based at least in part on detecting the first beam failure associated with the first communication node. The UE may detect a second beam failure associated with a second communication node. The UE may selectively transmit a second SR on a second SR resource indicated by the second SR configuration based at least in part on detecting the second beam failure associated with the second communication node and the configuration information. Other aspects are described.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) and/or a master node may use configurations to resume communications with one or more cells of a dual connectivity (DC) or carrier aggregation (CA) scheme. In some cases, the configuration may be used for a secondary cell group (SCG) of the DC scheme. This configuration may include the UE applying a previously stored configuration for the SCG (e.g., including higher-layer and lower-layer configurations of a last serving SN of the DC scheme) if it determines the previously stored configuration is valid. Additionally or alternatively, the configuration may include the network using a previous SCG configuration or reconfiguring the SCG and transmitting this indication in a resume communications message to the UE. In some cases, the network may determine this configuration based on assistance information or reports generated from the UE.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to transmit a packet based at least in part on receiving a packet data convergence protocol (PDCP) status report during an active state of a timer, or based at least in part on an expiration of the timer. The UE may transmit the packet based at least in part on the indication. Numerous other aspects are described.
