Abstract: Techniques for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling sidelink transmissions in one or more sets of multiple transmission time intervals (TTIs) over a shared spectrum. The UE may perform a listen-before-talk (LBT) for one or more of the TTIs in the one or more sets of multiple TTIs, and the UE may transmit, to a base station, an indication of results of the LBT performed for the one or more TTIs. Because the UE may provide the results of the LBT to the base station, the base station may be able to schedule sidelink transmissions from the UE based on the results of the LBT. As such, the UE may experience increased throughput in sidelink communications since the scheduling at the base station may be improved.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be scheduled for communicating a first message over a first communication link with a base station and a second message over second communication link with a second UE. The first UE may select to communicate using the first communication link or the second communication link based on one or more prioritization rules that may involve the priority of the first message and the second message. The first UE may identify a mapping between the priority of the first message and the priority of the second message that may enable a comparison of the priorities of the first message and the second message. The first UE may select to communicate using the communication link of the message associated with the higher priority.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of more than three orthogonal frequency division multiplexing (OFDM) symbols in the time domain to a control resource set (CORESET). In a first aspect, a method for wireless communication includes receiving, from a base station at a user equipment (UE), a first message that indicates a CORESET configuration. The CORESET configuration allocates more than three OFDM symbols in the time domain to a CORESET. The method further includes monitoring a set of time and frequency resources to receive a second message from the base station at the UE. The set of time and frequency resources have the CORESET configuration. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described that support discontinuous scheduling. A base station may transmit, to a user equipment (UE), a grant of resources of a communication channel over a multiple of aggregated TTIs. The UE may monitor a control channel for the grant of resources transmitted by base station. The base station and the UE may identify a location of an excluded TTI within the plurality of aggregated TTIs. The excluded TTI may correspond to a TTI for communicating synchronization signals, random access channel (RACH) signals, or the like. The base station may communicate with the UE via the resources of the communication channel over at least a subset of the aggregated TTIs based on the grant and the location of the excluded TTI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink message that includes a control channel monitoring periodicity and control channel offset for a radio frame. A UE may identify a set of slots within a radio frame to monitor for downlink control information (DCI) based on the received downlink message. The UE may identify a control channel candidate within a search space of each slot of the set of slots, and may identify the control channel candidate of a first slot based on calculations that include a current slot and a previous slot. There may be one or more slots that occur between the previous slot and the current slot. The UE may receive DCI that is user-specific based on the identified control channel candidate.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, a configuration indicating a channel quality threshold that the UE may use to identify an interference-based beam failure indicator type. The UE may receive a reference signal for performing one or more signal measurements in accordance with the configuration. Based on the one or more signal measurements and the channel quality threshold, the UE may report an indication of the type of beam failure indicator to the base station.

Abstract: Aspects are provided in which narrow channels are configured and carrier aggregated with defined channel bandwidths in order to support irregular channel bandwidths that are not a multiple of 5 MHz or other defined bandwidth multiple. An apparatus such as a UE receives, from a base station, a configuration for carrier aggregation for a PCell and one or more SCells. A total bandwidth of the PCell and the one or more SCells is not a defined bandwidth multiple. The apparatus communicates with the base station through the PCell and the one or more SCells. In this way, the available spectrum of wireless operators that include channel bandwidths of irregular size may be supported.

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

Abstract: Orthogonal frequency-division multiplexing (OFDM) numerologies that maintain symbol boundary alignment while distributing excess cyclic prefixes (CPs) among OFDM symbols. Communication is established using a first sub-carrier spacing (SCS) and a first OFDM numerology, such as an exemplary numerology that distributes excess CP duration among a set of symbols that occupy a time interval within or equal to a corresponding time interval of a symbol of a second OFDM numerology with a second lower SCS. The first SCS may be, e.g., 960 kHz. The second SCS may be, e.g., 120 kHz. Another exemplary OFDM numerology described herein distributes the excess CP as prefix and postfix portions to one of the symbols, such as the first symbol of a set. Communication then proceeds using the first OFDM numerology at the first SCS and, in illustrative examples, using the second OFDM numerology at the second SCS or other OFDM numerologies at other SCSs.
