Abstract: Aspects of the disclosure relate to random access procedures. In one example, a user equipment (UE) can multiplex an uplink (UL) message with uplink control information (UCI) on a data region of a first slot and transmit the multiplexed UL message with the UCI to a base station in UL transmission or UL retransmission as part of the random access procedure. The UE may further employ UL message repetition to be transmitted with the multiplexed UL message with the UCI. The base station may receive the multiplexed UL message with the UCI with or without UL message repetition. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive first control signaling indicating a first network operation sequence associated with a first component carrier, the first network operation sequence including a first set of time intervals corresponding to a first set of network operation modes for the first component carrier. The UE may additionally receive second control signaling indicating a second network operation sequence associated with a second component carrier, the second network operation sequence including a second set of time intervals corresponding to a second set of network operation modes for the second component carrier. The UE may then communicate via the first component carrier in accordance with the first network operation sequence, and communicate via the second component carrier in accordance with the second network operation sequence.

Abstract: A user equipment (UE) may be configured to encode at least one partial uplink (UL) repetition using a sequence-based encoding based on a codebook, the first partial UL repetition not including a demodulation reference signal (DM-RS). A base station may transmit a configuration of the encoding scheme of the partial UL repetitions to the UE, and the UE may encode the at least one partial UL repetition based on the received configuration. The base station may decode the received at least one partial UL repetition based on the configuration.

Abstract: Methods, systems, and devices for wireless communications are described that relate to a two-step random access procedure. Generally, the described techniques allow different configurations for a first message of a random access procedure depending on a connected-state of the user equipment (UE) performing the random access procedure. A base station may transmit configuration information to the UE and the UE may use the configuration information to determine resources, coding, block size, or other factors for transmitting the first message based on the radio resource control (RRC) connected state of the UE. The UE may then monitor for a random access response from the base station based on the first message from the UE.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive downlink control information (DCI) comprising an indication of a bandwidth part (BWP) switch for a secondary cell to a dormant BWP and transition the secondary cell from an active state to a dormant state based on the indication of the BWP switch of the secondary cell to a dormant BWP.

Abstract: Methods, systems, and devices for wireless communications are described for cell access techniques in carrier aggregation configurations in which one or more carriers do not provide discovery signals such as synchronization signal block (SSB) transmissions. A UE may be configured with an anchor carrier on which SSBs are transmitted, and one or more non-anchor carriers on which SSBs are not transmitted. A single cell barring indication may be provided for the anchor carrier, in which case the UE may follow cell barring indications for associated non-anchor carriers. In other cases, separate cell barring indications may be provided for one or more anchor carriers and one or more non-anchor carriers.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a system information block (SIB) that indicates a selected set of message repetition numbers from a plurality of sets of message repetition numbers. The UE may receive, from the base station, a bit field in a random access response (RAR) or downlink control information (DCI) that indicates a selected message repetition number from the selected set of message repetition numbers indicated in the SIB. The UE may transmit, to the base station, a message during a random access procedure based at least in part on the selected message repetition number. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to bandwidth-efficient utilization of peak reduction tone resource are provided. An example method of wireless communications performed by a user equipment (UE) includes receiving, from a base station in a first subband, a resource allocation indicating a set of transmission tones comprising a set of first data tones, a set of second data tones and a set of peak reduction tones (PRTs). The resource allocation can indicate the set of first data tones overlaps at least a portion of the set of PRTs at respective locations of a set of PRT locations and the set of second data tones is arranged at a set of data tone locations within a particular bandwidth. The UE can communicate, with the base station in a second subband, a data transmission using an outgoing waveform based at least in part on the resource allocation.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to system information acquisition over bandwidth parts (BWPs) in communications system operating according to new radio (NR) technologies. In an exemplary method, a user equipment (UE) receives system information (SI) via a transmission in a downlink (DL) bandwidth part (BWP) of a system bandwidth and transmits, to a serving base station (BS) and in response to receiving the SI, an indication that the UE has completed SI acquisition.
