Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station during a connection establishment procedure, a UE message indicating support for a plurality of connected modes, where the plurality of connected modes includes a first connected mode. The UE may receive, based at least in part on the UE message, a configuration message from the base station configuring resources for the UE to use while operating in the first connected mode. The UE may perform a grantless communication with the base station while operating in the first connected mode and using the configured resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to frequency hopping within a virtual BWP. In some aspects, a UE may determine a virtual bandwidth part (BWP) in which to frequency hop from a first narrow BWP to a second narrow BWP by a frequency offset. The virtual BWP may have a same subcarrier spacing as the first narrow BWP and a larger bandwidth than the first narrow BWP. The UE may perform communication based at least in part on frequency hopping within the virtual BWP. Numerous other aspects are provided.

Abstract: In an aspect, a serving BS of a UE measures ToAs of a DL-PRS from a non-serving base station of the UE and an UL-SRS-P from the UE. The serving BS transmits measurement information based on the ToA measurements of the DL-PRS and the UL-SRS-P to a position estimation entity. The position estimation entity determines a positioning estimate for the UE based in part upon the measurement information.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to adjust a random access message that is transmitted to a base station in an asynchronous uplink transmission. The UE may use a constrained mapping of time and frequency resources for the random access message or transmit all portions of the message in a continuous transmission. The UE may also adjust the timing of the portions of the message. The base station may use a portion of the message, such as a preamble, to perform channel estimation for another portion of the message, such as a payload, to improve decoding of the transmitted message. Additionally, the UE may configure a waveform of the message to improve the continuous transmission of the message, for example by reducing interference between portions of the message.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configuring associations between system information of at least one downlink (DL) anchor carrier and at least one random access channel (RACH) occasion (RO) of an uplink (UL) anchor carrier for initial access in flexible multicarrier operations. System information may be transmitted by a base station to a UE over the DL anchor carrier. In aspects, the at least one DL anchor carrier may be mapped to an UL anchor carrier, or to one or more candidate UL anchor carriers from which the UE may configurably select the UL anchor carrier, for initial access operations. In aspects, the UL anchor carrier and/or the one or more candidate UL anchor carriers may be respectively associated with one or more ROs. The UE may perform initial access operations over the UL anchor carrier using the associated one or more ROs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to-detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.

Abstract: A user equipment (UE) may report capabilities pertaining to UE feedback processing, such as a number of simultaneous feedback reports that can be processed and reported by the UE for various types of feedback. For example, UE feedback processing capability may depend on channel state information (CSI) processing units (CPUs) available to the UE for feedback processing operations (e. g., for performing channel measurements, processing feedback, generating a feedback report, etc.). A UE may report feedback processing capability separately for periodic feedback reporting and for aperiodic feedback reporting, for different types of feedback reporting (e. g., for CSI reporting, for beam management reporting, etc.), etc. As such, a UE may more efficiently report capabilities pertaining to UE feedback processing, and a base station may more efficiently configure UE feedback reporting according to UE feedback processing capability.

Abstract: Methods, systems, and devices for wireless communications are described for a two-step random access channel (RACH) procedure in which uplink random access preamble and message transmission occasions may span multiple transmission slots. Reference signal resources for transmitting a reference signal with a first random access message of the two-step RACH procedure may include at least one symbol in each of the multiple transmission slots. The reference signal resources, reference signal sequence, or both, may be identified based on a particular uplink random access message transmission occasion, random access preamble transmission occasion, random access preamble sequence configuration, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a mapping between synchronization signal blocks (SSBs) and a random access message of a two-step random access procedure based on an indication in system information signaling or radio resource control (RRC) signaling. The random access message may include a random access preamble and a random access payload. The UE may determine, based on the mapping, an association between one or more beams carrying the SSBs and one or more additional beams carrying the random access preamble and the random access payload of the random access message. As a result, the UE may perform the two-step random access procedure with a base station according to the beam association, and coexist with a four-step random access procedure in a more reliable and efficient manner.
