Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

Abstract: Some techniques and apparatuses described herein may be used to avoid or reduce collisions between uplink data communications and uplink control communications for an enhanced machine-type communication user equipment (eMTC UE) operating in an unlicensed radio frequency spectrum band. Furthermore, some techniques and apparatuses may avoid such collision while still allowing efficient use of resources, such as by deferring the uplink data communication within a data segment, rate matching an uplink data communication around uplink control resources (e.g., cell-specific uplink control resources and/or UE-specific uplink control resources), puncturing the uplink data communication to avoid the uplink control resources, multiplexing uplink control information on an uplink data channel, and/or the like.

Abstract: Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. 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, an event trigger may be based on aggregated measurements from multiple links.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure a system bandwidth of shared spectrum partitioned into a plurality of bandwidth parts based on interference associated with each of the plurality of bandwidth parts. The base station may then transmit the configuration of the system bandwidth to a plurality of devices. A UE may receive, from a base station, a configuration of a system bandwidth of shared spectrum. The system bandwidth may be partitioned into a plurality of bandwidth parts based on interference associated with each of the plurality of bandwidth parts. The UE may then communicate with the base station on at least one of the bandwidth parts.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a transmission detection procedure on each base station before combining control information. The UE may use demodulation reference signals (DMRS) as a detection mechanism. If the UE detects a DMRS from a base station, the UE may determine that a control resource set associated with the base station is valid for combining. If the UE does not detect DMRS from the base station, the UE may refrain from combining control information from the base station. In another example, base stations that pass a listen-before-talk (LBT) pr6ocedure may transmit a preamble before transmitting control information. A preamble may carry a preamble sequence associated with a specific control resource set. The UE may identify a preamble sequence and determine that the corresponding control resource set is valid for control information combining.

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.

Abstract: Wireless communications systems and methods related to coordinating shared radio resources for spectrum sharing are provided. A spectrum resource control unit allocates a first resource for exclusive access by a first network operating entity in a spectrum. The exclusive access is configured for at least one of a network information communication or a feedback communication. The spectrum resource control unit allocates a second resource in the spectrum for shared access by the first network operating entity and a second network operating entity. The shared access is configured for at least a downlink control information communication. The spectrum resource control unit transmits, to the first network operating entity and the second network operating entity, a configuration indicating the first resource allocated for exclusive access by the first network operating entity and the second resource allocated for shared access by the first network operating entity and the second network operating entity.
