Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a downlink control information (DCI) message including an indication to enable discontinuous monitoring of a physical downlink control channel (PDCCH). The UE may enable the discontinuous monitoring of the PDCCH based on the received DCI message, and disable monitoring of the PDCCH during a temporal period in which at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled. The UE may thereby experience power saving by disabling monitoring of the PDCCH while still performing other wireless operations during the temporal period. The UE may, as a result, also include features for improvements to wireless communications and, in some examples, may promote high reliability and low latency wireless communications, among other benefits.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain configurations, the apparatus may include an eMBB UE. The apparatus may monitor a single preconfigured mini-slot in each of a plurality of slots for a PI. The apparatus may receive the PI in the single preconfigured mini-slot of a first slot of the plurality of slots. In certain aspects, the PI may include a resource index associated with a reduced transmission power by the UE. In certain other aspects, the resource index may include one or more resources in a second slot. The apparatus may transmit at least one packet with the reduced transmission power on the one or more resources in the second slot or refraining from transmitting the at least one packet on the one or more resources in the second slot.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message configuring the UE to communicate coordinated transmissions with multiple transmission reception points (TRPs) using a first coordinated transmission mode of a set of different coordinated transmission modes. The UE may receive, based on the configuration message, downlink control information including at least one indicator and receive a first coordinated transmission communicated in accordance with the first coordinated transmission mode. The UE may transmit, in accordance with a feedback configuration corresponding to the at least one indicator and the first coordinated transmission mode, a feedback message for the first coordinated transmission to at least one of the multiple TRPs.

Abstract: Wireless communications systems and methods related to full-duplex cooperative communication by a first device tethered with a second device communicating with a third device. With the tether, one device between the first device and the second device is designated or selected as a transmitter, and the other device as a receiver. In full-duplex operation, the transmitter may transmit outgoing data concurrent to the receiver receiving incoming data. In an example, one of the first and second devices may have a modem that is used to control the full-duplex communication. The modem controls both transmission and reception. In another example, both devices may have a modem. Each modem may assume responsibility for part of the full-duplex communication by performing some processing before either shipping received data, or transmitting outgoing data. The amount of processing may be split at a link layer. Interference cancellation may mitigate interference from full-duplex operation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant that identifies a set of uplink resources. The UE may determine whether a timing of the grant overlaps with a repetition window of a grant-free uplink communication configured on the UE. The UE may process the grant based at least in part on whether the timing of the grant overlaps with the repetition window of the grant-free uplink communication. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide a mechanism for utilizing uplink hopping patterns for HARQ transmissions. Each hopping pattern may include a sequence of different frequency resources or a sequence of different scrambling sequences for a user equipment (UE) to utilize over time for HARQ transmissions. Each of the hopping patterns may further be associated with a time index mode in which the hopping pattern is applied to time resources such that each time resource within a consecutive sequence of time resources is mapped to a different frequency resource or scrambling sequence. The base station may select a hopping pattern for a particular UE and transmit an indication of the selected hopping pattern to the UE.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may receive configuration information that signals a first set of resources and a second set of resources. The configuration information may indicate that the first set of resources is associated with high priority transmissions and the second set of resources is associated with low priority transmissions. The UE may select, based at least in part on the configuration information and a priority of a transmission, either the first set of resources or the second set of resources for transmitting the transmission. The selecting of the first set of resources or the second set of resources may be based on latency requirements or reliability requirements of transmissions to be transmitted by the UE. The UE may transmit the transmission using the selected set of resources. Other aspects are provided.
