Abstract:
Aspects described herein relate to configuring and indicating radio resource control (RRC) message types in wireless communications, to support new UE categories, new operation modes, new use cases, or a combination thereof. Configuration and indication methods that may support co-existence of new and legacy RRC message types and/or user equipment (UE) procedures for decoding new RRC message type are also described.
Abstract:
A user equipment (UE) may receive an indication of a frequency allocation of at least one of a dynamic resource grant, a semi-persistent scheduling (SPS) activation message or assignment, or a control resource set (CORESET) configuration for one or more communications with a base station. The UE may receive a set of channel state information reference signals having a configuration that is based at least in part on the frequency allocation of the at least one of the dynamic resource grant, the SPS activation message or assignment, or the CORESET configuration.
Abstract:
This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a user equipment (UE) may generate an indication of a first doppler shift associated with the wireless communication device moving with reference to a first target base station (BS), obtain, from the serving BS, a handover command for conditional handover (CHO) (with the handover command including a first trigger for handover to the first target BS), and synchronize with the first target BS during CHO after the first trigger is met, wherein the first trigger is associated with the first doppler shift. In another aspect, a serving BS generates the handover command for CHO and provides the handover command to the UE. The UE is to synchronize with the first target BS during CHO after the first trigger associated with a first doppler shift is met.
Abstract:
Certain aspects of the present disclosure provide techniques for coordinated sidelink power savings configurations. A wireless node may select a sidelink power savings configuration to use for a sidelink between the wireless node and a user equipment (UE), provide the selected configuration to the UE, and follow the configuration for the sidelink. The selection may be based on input from the UE or without input from the UE. The selection may be a current power savings configuration at the wireless node, a power savings configuration suggest by the UE, or a different power savings configuration determined by the wireless node based on the current and suggested power savings configuration. When a new UE connects to the wireless node, the wireless node may reselect a power savings configuration to use for the sidelinks and provide the reselected power savings configuration to the UEs having a sidelink with the wireless node.
Abstract:
Techniques and apparatus for a control plane design for bandwidth part (BWP) in new radio (NR) are provided. One technique includes sending information with an indication of a BWP capability of a user equipment (UE) to a base station (BS). A configuration from the BS indicating a set of BWPs available to use for communication is received in response to the indication. Communications are performed on at least one of the set of BWPs. Another technique includes receiving information having an indication of a BWP capability of the UE. A configuration indicating a set of BWPs available for the UE to use for communication is determined. The configuration is sent to the UE.
Abstract:
Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.
Abstract:
Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.
Abstract:
Methods and apparatus are described for reducing round-trip time (RRT) for communications between a proxy and a browser. The methods and apparatus may include receiving a webpage from a server in response to forwarding to the server a first request received from the browser. Further, the methods and apparatus may include parsing the webpage for one or more object identifiers. Moreover, the methods and apparatus may include requesting one or more objects from the server based on the one or more object identifiers. Additionally the methods and apparatus may include storing the one or more objects received from the server.
Abstract:
Certain aspects of the present disclosure provide techniques for techniques for determining when to perform medium access control (MAC) control element (CE) (MAC-CE) triggered actions across multiple user equipments (UEs). A method includes receiving a MAC-CE comprising an indication to perform one or more actions and an indication of an absolute application time; and based on receiving the MAC-CE, perform the one or more actions at the absolute application time.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration indication that specifies a configuration of multiple operating zones that are based at least in part on a first range of potential values for a first operating metric and a second range of potential values for a second operating metric. The UE may transmit an operating state indication that indicates a particular operating zone of the multiple operating zones. The UE may receive scheduling information that is based at least in part on the particular operating zone. Numerous other aspects are described.
