Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a neighbor cell and report the result to a serving base station. Based on the report, the serving base station may identify an estimated discovery reference signal (DRS) transmission window of the neighbor cell. In some cases, the UE may estimate and report parameters of the neighbor DRS transmission window, and in other cases, the UE may make a measurement report and the base station may infer DRS transmission window parameters. The base station may then provide the UE with a DRS measurement timing configuration (DMTC) based on the estimated parameters of the neighbor cell so that the UE may monitor the neighbor cell and the serving cell in an efficient manner. For example, the UE may conserve battery life by refraining from monitoring DRS during periods when a DRS transmission is not likely.

Abstract: There may be a gap between the time a beam pair link (BPL) impacted by a beam failure (BF) event is deactivated and the time a replacement BPL is activated and becomes fully functional at a UE. The gap may be called a blackout period. A base station may not know the blackout period and may continue transmitting to the UE on the impacted BPL during the blackout period. This may result in a transmission failure. Disclosed herein are apparatus and methods for determining a blackout period associated with a beam failure (BF) event and communicating a blackout indication to a base station, the blackout indication including the blackout period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink beam indication for at least one of a channel, a resource, a resource set, a bandwidth part, or a component carrier; and use the downlink beam indication for a group of channels, resources, resource sets, bandwidth parts, or component carriers. In some aspects, a UE may receive an indication of a spatial relation and multiple physical uplink control channel (PUCCH) resources to which the spatial relation is to be applied; and use the spatial relation to transmit on one or more PUCCH resources of the multiple PUCCH resources. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide a scheduling entity in communication with a set of scheduled entities within a wireless communication network. The scheduling entity groups a plurality of tones into uplink clusters, where each uplink cluster includes one or more adjacent tones. In addition, the scheduling entity maps a first set of uplink clusters to a first virtual cluster group (VCG) for an uplink control channel, assigns the first VCG to a first scheduled entity of the set of one or more scheduled entities, provides a first VCG index identifying the first VCG to the first scheduled entity and receives uplink control information from the first scheduled entity on the first VCG over the uplink control channel.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to semi-persistent configuration of reference signals (RSs), such as measurement reference signals (MRSs) for beam refinement. An example method generally includes transmitting, to a user equipment (UE), a reference symbol (RS) configuration, wherein transmitting the RS configuration is independent of activating RS training for the UE, transmitting, to the UE, a message indicating an activation of RS training subsequent to transmitting the RS configuration, transmitting RSs to the UE periodically based on the RS configuration, and receiving, from the UE, measurement reports based on the transmitted RS.

Abstract: Certain aspects of the present disclosure provide techniques for random-access channel (RACH) communication. For example, certain aspects provide a method for providing an indication, via a first uplink transmission, of a preferred beam for a subsequent (uplink or downlink) transmission.

Abstract: In a process of beam change, the base station transmits a beam change instruction to a user equipment to confirm a change from a current beam to another beam. The base station determines to change from a first beam to a second beam. The base station generates a beam change instruction to indicate the determination to change from the first beam to the second beam. The base station transmits, to a UE, the beam change instruction in a downlink control information (DCI). The base station determines whether or not the beam change instruction is detected by the UE.

Abstract: Aspects of the disclosure provide a slot structure (e.g., the arrangement of channels and pilot signals within a slot) that can relax the processing timeline for a wireless communication device. For example, in the first or initial symbol of a slot, control information may be frequency division multiplexed (FDM) with a demodulation reference signal (DMRS) or with user data. In some cases, delayed-processing data may be sampled, and the samples may be buffered at the receiving device, for processing later, after control information needed to process the data has been received and processed. Further aspects provide for payload pre-tapering. That is, when a device delays the processing of data bits, this can cause a processing bottleneck after that buffering delay. By virtue of various pre-tapering techniques described herein, the processing load needed to process the delayed-processing data can be reduced. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining when to transmit a beam report indicating a new beam for communicating with a base station after a current beam used for communications with the base station fails. In one example, after detecting beam failure, a user equipment (UE) may compare a quality of each candidate beam available for communicating with a base station to a beam identification threshold, and the UE may perform beam reporting based on the comparisons (e.g., refrain from transmitting a beam report if the quality of each of the candidate beams is lower than the beam identification threshold). In another example, after detecting beam failure, a UE may compare a quality of each candidate beam available for communicating with a base station to a beam detection threshold, and the UE may perform beam reporting based on the comparisons.

Abstract: Methods, systems, and devices for wireless communications are described to enable base station and a user equipment (UE) to mitigate interference when using full-duplex communications. For example, a base station communicating with a UE via full-duplex communications may indicate for the UE to align the time of its uplink transmissions with the time the UE receives downlink transmissions. Additionally or alternatively, the base station may indicate a timing alignment window for the UE, where the window may consist of an allowed time period the UE may use to select a time to begin uplink transmissions. In some examples, the base station may select a cyclic prefix for full-duplex communications, where the cyclic prefix may be longer than a cyclic prefix used for other communications. Further, the base station may select uplink frequency and downlink frequency bands separated by a defined guard band for full-duplex communications.
