Abstract: Methods, systems, and devices are described for wireless communication employing two-stage control channel messaging. Systems, methods, and apparatuses for two stage two-stage physical downlink control channel (PDCCH) with a downlink control information (DCI) flag and DCI format size indicator are described. For instance, the present disclosure presents an example method of wireless communication at a wireless device, which may include receiving, at a first bandwidth and during a transmission time interval (TTI), a first control channel message. In addition, the example method may include determining, based on a flag in the first control channel message, whether a second control channel message is present in the TTI. Furthermore, the example method may include receiving, at a second bandwidth, the second control channel message where the flag indicates that the second control channel message is present for the TTI.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may employ a multiplexing configuration based on latency and efficiency considerations. The base station may transmit a resource grant, a signal indicating the length of a downlink (DL) transmission time interval (TTI), and a signal indicating the length of a subsequent uplink (UL) TTI to one or more user equipment (UEs). The base station may dynamically select a new multiplexing configuration by, for example, setting the length of an UL TTI to zero or assigning multiple UEs resources in the same DL TTI. Latency may also be reduced by employing block feedback, such as block hybrid automatic repeat request (HARQ) feedback. A UE may determine and transmit HARQ feedback for each transport block (TB) of a set of TBs, which may be based on a time duration of a downlink TTI.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a network may schedule a user equipment (UE) for multiple transmission/reception point (TRP) communication. The network may transmit a single downlink control information (DCI) message to the UE to dynamically configure multiple transmission configuration indicator (TCI) states for the multiple TRPs. In a first example, the DCI message may include a bit field indicating a set of antenna ports and the multi-TRP scheme for transmission. In a second example, the DCI message may include a separate field indicating the multi-TRP scheme (e.g., based on UE capabilities). In a third example, the DCI may indicate redundancy versions (RVs) for different TRPs in an RV field or across multiple fields. In a fourth example, the DCI may include an indication of a precoding resource block group (PRG) size that may be interpreted differently based on the indicated multi-TRP scheme.

Abstract: In order to overcome problems that a UE may face in determining a default beam for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL assumptions, UL resources, and/or spatial relationships are selected for a COT. A UE receives, from a base station, an indication corresponding to a COT. The indication is for at least one of a set of CORESETs, a set of QCL assumptions, a set of UL resources, or a set of spatial relations for determining a default beam. The UE determines the default beam from the base station for use during the COT based on the indication. The UE transmits or receives a transmission using the default beam.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor for discovery reference signal (DRS) transmissions, physical downlink shared channel (PDSCH) transmissions, or combinations thereof within a DRS transmission window. The UE may attempt to decode DRS or PDSCH transmissions for a subframe based on detection of DRS transmissions, prioritization of DRS transmissions relative to PDSCH transmissions, locations of subframes within a radio frame, overlapping of the DRS transmission window with a paging opportunity, or any combination thereof. In some cases, one or more radio link monitoring (RLM) parameters may be adjusted based on decoding of PDSCH or DRS transmissions.

Abstract: Wireless communications systems and methods related to transmitting communication signals are provided. A first wireless communication device performs a first LBT during a first time period for transmitting a first communication signal associated with a first priority. The first wireless communication device performs a second LBT during a second time period for transmitting a second communication signal associated with a second priority, wherein the first time period is at least partially overlapping with the second time period, and wherein the first priority is different from the second priority. The first wireless communication device communicates with a second wireless communication device, at least one of the first communication signal or the second communication signal based on at least one of the first LBT or the second LBT.
