Abstract: Methods, systems, and devices for wireless communication are described to support reducing conflicts with between scheduling request opportunities and downlink resources. A base station may configure a user equipment (UE) with a scheduling request periodicity and offset for identifying scheduling request opportunities. The UE and base station may apply the periodicity and the offset to a first subset of time periods of a set of multiple time periods, where the first subset of time periods may include scheduling request opportunities that do not overlap with resources allocated for downlink transmissions. Based on applying the offset and periodicity to the first subset of time periods, the UE may identify a scheduling request opportunity, in a first time period of the first subset, and may transmit a scheduling request to the base station via the scheduling request opportunity.

Abstract: This disclosure provides systems, methods and apparatus, for measurement and reporting procedures associated with a sidelink positioning reference signal (SL-PRS). In one aspect, a first user equipment (UE), which may function as a sidelink anchor node, may transmit an SL-PRS to a second UE in accordance with a slot format or structure that is dedicated for SL-PRS transmissions. The first UE may select resources for the transmission of the SL-PRS via sensing and exclusion or using a set of resources that are dedicated for SL-PRS transmissions. The second UE may receive the SL-PRS and use the SL-PRS to acquire positioning information, in accordance with an observed time difference of arrival (OTDOA)-based positioning method, or may transmit a second SL-PRS to the first UE to facilitate acquisition of positioning information at the first UE, in accordance with a round-trip-time (RTT)-based positioning method.

Abstract: Methods, systems, and devices for wireless communications are described in which a narrowband device may communicate in a wireless communications network according to frequency hopping techniques. Devices using narrowband communications and frequency hopping techniques may maintain separate radio link monitoring (RLM) processes, beam failure detection (BFD) processes, beam failure recovery (BFR) processes, or combinations thereof, for multiple bandwidth parts (BWPs) or hop regions of a full channel bandwidth. Such separate processes may provide for enhanced estimates of beam failures per BWP or hop region, which may be used to enhance communications reliability.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of modulations for a random access message associated with a two-step random access channel (RACH) procedure. The set of modulations may be either a first set of modulations or a second set of modulations that is different from the first set of modulations. The set of modulations may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The UE may transmit the random access message based at least in part on the determined set of modulations. The random access message may include a physical uplink shared channel modulated using the determined set of modulations. Numerous other aspects are provided.

Abstract: Aspects relate to spectrum sharing for use in a wireless communication network that serves both prioritized and non-prioritized user access terminals. In one example, a user access terminal, e.g., a user equipment (UE), senses an amount of signal energy within a frequency band during one or more sensing intervals in response to a determination that the access terminal is a non-prioritized access terminal. If the amount of signal energy does not exceed a sensed energy threshold, the user access terminal transmits wireless signals following the sensing intervals. On the other hand, if the amount of signal energy exceeds the sensed energy threshold, the user access terminal modifies transmissions while the amount of signal energy sensed during one or more subsequent sensing intervals exceeds the sensed energy threshold. For example, the access terminal may delay or adjust transmissions until the amount of signal energy no longer exceeds the sensed energy threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message which schedules a sidelink transmission from the first UE to a second UE on a first set of resources associated with a sidelink shared channel. The first UE may additionally receive a second DCI which indicates a second set of resources which are cancelled from the first set of resources. Based on the cancellation indication, the first UE may modify or cancel at least a portion of the sidelink transmission originally scheduled for the second UE, and may transmit the modified sidelink transmission over a portion of the first set of resources in accordance with the cancellation indication, the first DCI, and the second DCI.

Abstract: Some aspects provide a method for wireless communication by a first wireless device. The method generally includes transmitting one or more sidelink channel state information (CSI) reference signals (CSI-RSs) targeting a group of user equipments (UEs). The method generally includes requesting one or more CSI reports from a selected one or more UEs of the group of UEs. The method generally includes receiving one or more CSI reports from the selected one or more UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A downlink message associated with a feedback process identifier may be received at a first time. An uplink feedback message for the downlink message may be scheduled for a third time. Another downlink message associated with the feedback process identifier may be received after the first time and before the third time. Additionally or alternatively, an uplink grant associated with a feedback process identifier may be received at a first time. An uplink message may be scheduled by the uplink grant for a third time. Another uplink grant associated with the feedback process identifier may be received after the first time and before the third time, and another uplink message may be scheduled by the other uplink grant for a fourth time after the third time.

Abstract: Techniques are described herein for beam pair link procedures used in dual connectivity operations. A master base station may be configured to determine a timing window for a user equipment (UE) to monitor a downlink channel associated with a secondary base station. In some cases, the master base station may determine the timing window during a dual connectivity procedure or during a carrier aggregation procedure. The UE may monitor the downlink channel during the timing window and establish a beam pair link with the secondary base station based on the monitoring.

Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.
