Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for enabling user equipment (UE) mobility within an area. In one aspect, a base station (BS) may configure a set of cells for serving a UE, as well as a set of relay UEs to relay communications for the UE, for example via sidelink communications. The BS may transmit control signaling to the UE indicating the configured set of cells and the set of relay UEs. The UE may establish communications links via sidelink connections with one or more of the relay UEs, and determine an activated subset of cells for data and control transfer. In some implementations, the UE may be configured to autonomously activate or deactivate relay UEs based on the mobility of the UE, and report the activation or deactivation to the BS.

Abstract: Certain aspects of the present disclosure provide various synchronization channel and physical broadcast channel (PBCH) designs. A method for wireless communications by a user equipment (UE). The UE detects a synchronization channel and a secondary synchronization signal (SSS) transmitted with the synchronization channel. The UE demodulates a PBCH based on the SSS and determines system bandwidth corresponding to the downlink bandwidth based on system information in the PBCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a serving base station may identify that the UE is a potential victim of interference from a neighboring base station. The UE may transmit an interference coordination message to the neighboring base station. The interference coordination message may request modification of one or more transmission parameters at the neighboring base station. The neighboring base station may modify its transmission parameters to decrease interference with the UE, and the UE may communicate with the serving base station after transmitting the interference coordination message.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support aperiodic and cross component carrier PRSs. Generally, the described techniques provide for receiving a dynamic trigger indicating that a UE is to monitor for one or more downlink positioning reference signals (PRSs). The UE may generate a timing measurement for the one or more downlink PRSs, and may transmit a measurement report that indicates the timing measurement to a transmission/reception point. A UE may also transmit a capability indicator, indicating that the UE is capable of maintaining phase coherence for a PRS that spans multiple component carriers, receive control signaling that indicates multiple component carries on which the PRS is phase coherent, generate a timing measurement for the PRS based on the control signaling, and transmit a measurement report that indicates the timing measurement to the transmission/reception point.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request message to a base station while operating in an idle mode. The base station may generate, in response to the request message, a response message including a random access preamble index corresponding to the received request message. In some cases, the base station may determine a radio network temporary identifier (RNTI) based on the random access preamble index and scramble a cyclic redundancy check (CRC) of the response message with the RNTI. In some examples, the random access preamble index may be included in a payload of the response message. The UE may monitor a physical downlink control channel for the response message to the request message and receive the response message on the physical downlink control channel.

Abstract: This disclosure provides systems, methods and apparatus for wireless communications that support fallback from a 2-step to a 4-step random access procedures. A user equipment (UE) may establish a connection with a base station using a random access procedure. The random access procedure may be a 2-step random access procedure and reduce a number of handover exchange messages. The 2-step random access procedure may include the UE transmitting, to the base station, a first random access message including a preamble and a payload. In some implementations, the base station may receive the preamble but fail to receive or decode the payload. The random access procedure may utilize the received preamble information instead of performing retransmission of the first random access message. The base station may transmit a second random access message to the UE indicating, explicitly or implicitly, a fallback to a 4-step random access procedure for connection establishment.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to a physical uplink control channel (PUCCH) sequence design. In some cases, a UE receives (from a network entity, such as a base station/gNB) signaling indicating a base sequence from a set of base sequences available for use in sending one or more bits of uplink control information (UCI) within a transmission time interval (TTI), receives signaling indicating a set of feasible cyclic shifts, selects one of the cyclic shifts based on a value of the one or more bits of UCI, and transmits the UCI using the base sequence and the selected cyclic shift.

Abstract: Aspects described herein relate to configuring a media access control (MAC)-control element (CE) to update a sounding reference signal (SRS) beam within a wireless communication system. Other aspects described herein relate to configuring default beam information for determining a beam for data channel communications within the wireless communication system. A user equipment (UE) or other device can determine to use the default beam information for configuring the beam for a data channel communication and for performing power control using, e.g., physical uplink shared channel (PUSCH) parameters. In addition, in some examples, the device can transmit the data channel communication using a beam configured based on the default beam information.

Abstract: Methods, systems, and devices for wireless communications are described for block feedback of multiple semi-persistent scheduling (SPS) occasions. Block feedback may be provided based on variable feedback timing values that are associated with one or more SPS occasions. A user equipment (UE) may determine feedback for each of two or more SPS occasions, and transmit a block feedback that indicates the feedback. A separate feedback timing between a SPS occasion and uplink feedback resources may be provided for multiple SPS occasions, which are associated with a single uplink feedback resource. Alternatively, a minimum feedback timing value and a maximum feedback timing value may be configured for a particular uplink resource, and block feedback for multiple SPS occasions within the minimum and maximum feedback timing values may be reported in the uplink feedback resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration message indicating that transmission of a control message is to be repeated via a set of control message repetitions. The UE may identify that a repetition instance of the set of control message repetitions is designated as a triggering instance for a delay parameter, where the delay parameter corresponds to a time delay between the triggering instance and an operation associated with the control message. The UE may then receive, from the base station, the triggering instance during a first transmission time interval and perform the operation during a second transmission time interval that is after the first transmission time interval by at least the time delay.
