Abstract: A user equipment (UE) may operate in a reception mode that includes a set of sleep cycles and a set of wake cycles. During a sleep cycle of the UE, a signal quality of an active beam carrying a control channel or a data channel may degrade. This may result in the UE failing to decode the control channel or the data channel during a subsequent wake cycle. In some aspects, the UE may perform a measurement of one or more beams, of a set of beams, prior to the wake cycle. In some aspects, the UE may identify a beam, of the one or more beams, to use for communication with a base station (BS). In this way, the UE reduces a delay in data transfer associated with performing beam recovery after failing to decode the control channel or data channel during the wake cycle.

Abstract: Methods, systems, and devices for wireless communication are described for event triggering and reporting with multiple reference signals. A user equipment (UE) may receive event configuration data that specifies at least one permitted combination of reference signals of different types for generating a signal quality comparison and receive a first reference signal and a second reference signal. The UE may generate signal quality comparison data based at least in part on the event configuration data, the first reference signal, and the second reference signal, and transmit a report to a base station that includes the signal quality comparison data.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may receive a first measurement report from a user equipment (UE) that includes an indication of a measurement parameter associated with a first beamformed reference signal. The base station may receive additional measurement reports from the UE for additional base stations. The additional measurement reports may include an indication of measurement parameters associated with additional beamformed reference signals transmitted by the additional base stations. The base station may identify a location of the UE based on the first measurement report and the additional measurement report. Alternatively, the UE may transmit multiple beamformed sounding reference signals to multiple base stations, and a single base station may identify a location of the UE based on multiple reports collected from the multiple base stations.

Abstract: Various aspects of the disclosure relate to controlling reporting operations based on the timing of certain reporting events. In some aspects, the manner in which an apparatus performs reporting operations may depend on how far apart in time two reporting events occur. As one example, if the timing of an event-triggered report closely follows the timing of a request-triggered report, the apparatus may skip or otherwise alter the event-triggered reporting.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for beam recovery and radio link failure (RLF) in communications systems using beamforming and operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes communicating using beamforming with a base station (BS) via a transmit beam and a receive beam of an active beam pair and obtaining an indication of one or more alternative beams for the UE to use to send a beam recovery message to the BS in the event the transmit beam and the receive beam of the active beam pair become misaligned.

Abstract: Aspects of the disclosure relate to beam failure recovery requests. In one example, a beam failure of a beam is detected, and a determination is made of which beam failure recovery resources to utilize for a beam failure recovery request based on a network configuration. The beam failure recovery request can be transmitted via beam failure recovery resources. In another example, a scheduling entity determines beam failure conditions associated with detecting a beam failure, and ascertains a network configuration for a scheduled entity that can include parameters associated with the beam failure conditions, as well as parameters associated with determining beam failure recovery resources or for transmitting a beam failure recovery request. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support beamformed transmissions between devices (e.g., to improve coverage range). The beamformed transmissions may depend on discovery and maintenance of receive and transmit beams over which a given device may communicate with another device. Various receive and transmit beams for a given device may be compared using reference signals. As the number of devices attempting to access a cell increases, the number of reference signals to be transmitted may scale proportionally. Large numbers of reference signals may flood time-frequency resources of the system and/or require excessive processing at a mobile device. Scrambling sequences for reference signals may be employed to improve efficiency of resource usage. In aspects, the scrambling sequences may be implicitly determined (e.g., based on resources over which the access request was transmitted). Such an implicit association may reduce the need for additional signaling.
