摘要： Methods, systems, and devices for wireless communications are described. The method may include receiving from a master cell group of a dual connectivity environment a first message indicating that a secondary cell group of the dual connectivity environment is suspended, maintaining a lower layer configuration for the secondary cell group and modifying a measurement report configuration for the secondary cell group based on the first message and while the secondary cell group is suspended, receiving from the master cell group a second message indicating that the secondary cell group is no longer suspended, and reconnecting to the secondary cell group using the lower layer configuration for the secondary cell group based on the second message.

摘要： Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.

摘要： Wireless communications systems may support flexible waveform configuration for autonomous uplink transmissions. A base station may transmit broadcast signaling (e g , a system information block (SIB)) indicating waveform configuration information for an autonomous uplink transmission by a user equipment (UE). In some cases, the broadcast signaling may include a waveform configuration field (WCF) that may indicate whether flexible waveforms for autonomous uplink are supported, may configure a waveform type, may indicate waveform configuration mapping rules, etc. As such, a UE may identify whether flexible waveform configuration for autonomous uplink is supported, and may determine waveform types for autonomous uplink transmissions based on waveform type configuration information from a base station (e.g., which may include an indication of whether flexible waveform configuration is supported, an indication of waveform type/scenario mapping rules, etc.), one or more LUTs, identified autonomous uplink scenarios, autonomous uplink transmission parameters, or some combination thereof.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, one or more downlink reference signals. The UE may transmit, to the base station, a random access channel (RACH) message associated with a RACH procedure using a first RACH configuration that is associated with repetitions or a second RACH configuration that is not associated with repetitions based at least in part on whether a measurement of the one or more downlink reference signals satisfies a measurement threshold, wherein a selection of a RACH configuration is evaluated by the UE prior to a transmission of an initial message associated with the RACH procedure. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive first information indicating a first set of parameters associated with repetition of a second random access message (RAM) associated with a random access channel (RACH) procedure. The UE may transmit, using the first set of parameters, an initial RAM in association with the RACH procedure. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to configurations for new radio (NR) devices with reduced capabilities. In some aspects, a user equipment (UE) may determine a configuration from stored configuration information, where the configuration specifies a subset of features that NR UE with reduced capabilities is to support. The UE may communicate according to the configuration of reduced capabilities, or fall back to a set of further reduced UE capabilities. Numerous other aspects are provided.

摘要： Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.
