Abstract: Systems, methods, and devices for wireless communication that support mechanisms for enabling sidelink demodulation reference signal (DMRS) bundling in a wireless communication system. In aspects, a transmitting user equipment (UE) may be configured for sidelink communication with a receiving UE, and a sidelink DMRS transmission may be determined to be transmitted from the transmitting UE to the receiving UE. In aspects, determining whether to enable bundling of the sidelink DMRS transmission from the transmitting UE to the receiving UE or not (e.g., whether to enable or to forego enabling bundling of the sidelink DMRS transmission) may be determined in accordance with various aspects of the present disclosure.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a communication device may receive control signaling (e.g., a broadcasted control signal) from another communication device. The control signaling may indicate beam information for one or more beams of a set of beams. The one or more beams may correspond to the serving cell or one or more neighboring cells. The beam information may include one or more metrics associated with each of the one or more beams. As such, the communication device may determine that a metric associated with each of the one or more beams satisfies a threshold, select the beam, and communicate using the selected beam. In some other examples, the beam-specific information may include beam measurement offsets for one or more beams. In such examples, the communication device may select a beam based on the beam measurement offsets and perform communications using the selected beam.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, via first frequency ranges and first time periods, a plurality of sidelink control blocks that each indicate a sidelink positioning reference signal burst pattern for one or more sidelink UEs. The UE may receive, within a second frequency range and during a second time period, a plurality of multiplexed sidelink positioning reference signals from the one or more sidelink UEs in accordance with the sidelink positioning reference signal burst patterns. The UE may determine a position of the UE based at least in part on the receiving of the plurality of multiplexed sidelink positioning reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for using layer one (L1) or layer two (L2) signaling to indicate a primary cell (PCell) or primary secondary cell (PSCell) to a user equipment (UE). The use of L1 or L2 signaling to indicate a PCell or PSCell may be referred to as L1 or L2 mobility and may lower the latency at the UE associated with transitioning to communicating with the PCell or PSCell. A UE may receive radio resource control (RRC) signaling from a base station indicating a set of cells configured for L1 or L2 mobility and indicating a list of candidate cells for a PCell or PSCell. The UE may then receive L1/L2 signaling from the base station identifying the PCell or indicating activation of the PSCell.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, techniques for an enhanced paging procedure. A method that may be performed by a user equipment (UE) includes detecting, during a paging occasion (PO), at least one downlink control information (DCI) that indicates a paging message and additional downlink signals and using the additional downlink signals to enhance processing of the paging message.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) of a group of UEs may communicate with other members of the group to provide data or other information via sidelinks. The UE may transmit a groupcast sidelink request to the base station. After receiving the sidelink request, the base station may send a sidelink grant (e.g., transmit or receive grant) in downlink control information (DCI) to the UEs in the sidelink groupcast communications group. The sidelink grant may include information for each hop such as which UEs are going to transmit or receive, the reception or transmission beams of the UEs, time and frequency resources, or the data to forward or relay. In some examples, a UE may relay information to other UEs in the sidelink groupcast communications group.

Abstract: Methods and apparatuses for transmitting and detecting channel reservation preamble in a NR shared spectrum are described. An aspect may include determining whether a first reservation preamble of a first operator is received on a first time slot of multiple time slots of a downlink channel from a first network entity, and transmitting a second reservation preamble of the first operator on an uplink channel to the second network entity. Another aspect may include generating a first reservation preamble of a first operator based on at least one of a compressed representation in a signal space, a basis function of the signal space, or a CAZAC sequences; and transmitting, on a first timeslot of multiple time slots of a downlink channel, the first reservation preamble of the first operator to at least a UE.
