Abstract: Various aspects of the disclosure relate to communicating control information via interleaved symbols. For example, symbols of a first handshaking process may be interleaved with symbols of a second handshaking process. In some scenarios, the control information includes request-to-send (RTS) and clear-to-send (CTS) signaling. In some aspects, different tone spacing is used for the control information than is used for data within a subframe. In some aspects, a different cyclic prefix length is used for control information than is used for data within a subframe.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may measure one or more synchronization signal blocks (SSBs); determine that the one or more SSBs are associated with a first transmit receive point (TRP) based at least in part on identification information, associated with the one or more SSBs, that distinguishes the first TRP from a second TRP with a same physical cell identifier (PCI) as the first TRP; and transmit a measurement report, associated with the first TRP, based at least in part on measuring the one or more SSBs and determining that the one or more SSBs are associated with the first TRP. Numerous other aspects are provided.

Abstract: Various aspects of the disclosure relate to wireless communication that is synchronized across different wireless communication spectrum. For example, communication on an unlicensed spectrum may, in response to a particular trigger, switch to a licensed spectrum. Here, the switch may occur in a time synchronized manner (e.g., according to a frame structure). In addition, communication across such spectrum may be synchronized among multiple systems. For example, a controller may specify a reuse pattern to be used by the different systems for communication across unlicensed spectrum and licensed spectrum.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems support mobile broadband (MBB) communications and low latency communications. To accommodate low latency communications, a base station may identify resources allocated for MBB communications, and the base station may reassign (or puncture) these resources for low latency communications. The base station may transmit an indication of the reassigned (or punctured) resources to one or more user equipments (UEs). The base station may transmit an indication of the reassigned resources over a designated indication channel during a time period that is being reassigned for low latency communications (e.g., using a current indication). The base station may also transmit another or complementary indication of the reassigned resources in a subsequent time period (e.g., using a post indication), which may include supplemental or additional information.

Abstract: Methods, systems, and devices for wireless communication are described. A first UE and a second UE may coordinate to establish a sidelink connection. The first UE may identify data to transmit to the second UE, and the first UE may transmit a request to send (RTS) message to the second UE with a first transmit power. The first UE may then determine to refrain from using the first transmit power for the data transmission, and the first UE may transmit the data to the second UE with a second transmit power that is different from the first transmit power. The UE may determine the second transmit power for the data transmission based on instantaneous channel quality information (CQI) received in a clear to send (CTS) message, a modulation and coding scheme (MCS) selected for the data transmission, a threshold power, etc.

Abstract: An apparatus may configure x subframes with a subslot configuration that includes y subslots, y being greater than x. In an aspect, each subslot of the y subslots may include a first portion having one or more symbols for carrying at least one of data or control information, a second portion having a gap, and a third portion for carrying ACK/NACK information associated with the first portion. In an aspect, the second portion may be between the first portion and the third portion. In an aspect, the second portion and the third portion may include at most one symbol. The apparatus may send information indicating the subslot configuration to at least one neighboring base station. The apparatus may communicate content with a user equipment (UE) during at least one of the y subslots.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a negative acknowledgement (NACK) corresponding to a failed communication from a first transmission/reception point (TRP) included in a coordinated multipoint network. The UE may monitor a control channel associated with a second TRP included in the coordinated multipoint network based at least in part on transmitting the NACK, wherein the first TRP and the second TRP use different frequency bands. The UE may receive a retransmission of the failed communication based at least in part on monitoring the control channel. Numerous other aspects are provided.

Abstract: A user equipment (UE) may determine that a synchronous transmission by the UE includes traffic having a priority higher than a priority of nominal traffic. In response to the determination, the UE may, alter a use of at least some of an initial portion of a discovery frame from energy detection to signal transmission. The signal transmission may be a pilot signal transmission or a non-information-carrying signal transmission. The traffic having the priority higher than the nominal traffic may include mission-critical traffic. A reliability requirement of mission-critical traffic may be higher than a reliability requirement of nominal traffic. A latency requirement of mission-critical traffic may be lower than a latency requirement of nominal traffic. The signal transmission may be at a power level that is sufficient to result in energy detection at another UE. Various additional and alternative aspects are described herein.

Abstract: Methods, systems, and devices for wireless communication are described. A relay wireless node may receive, during a first transmit time interval (TTI), a data message to be forwarded to a wireless node. The relay wireless node may forward the data message to the wireless node during the first TTI. The relay wireless node may receive, during a second TTI, a feedback message from the wireless node. The relay wireless node may retransmit the feedback message during the second TTI.

Abstract: Aspects of the present disclosure describe an indication channel for wireless communications that indicates whether an ultra-reliable low-latency communication (URLLC) transmission is present in a current mini-slot within an enhanced mobile broadband (eMBB) slot. A base station may determine that an indication message is to be transmitted within the eMBB slot. The indication message may indicate that at least a portion of the mini-slot of the eMBB slot is used for the URLLC transmission. The base station may allocate one or more resources to an indication channel in a same mini-slot as the portion of the mini-slot to be used for the URLLC transmission. The base station may transmit the indication message during the mini-slot on the indication channel using the allocated one or more resources. A UE may receive the indication channel and process at least the portion of the mini-slot based on whether the indication message is received.
