Abstract: Methods, systems, and devices for wireless communications are described. One method may include receiving, by a user equipment (UE) from a base station, a resource allocation indicator corresponding to a total number of resource elements to allocate for uplink control information within a resource allocation of a shared data channel. The UE may determine anchor resources within the resource allocation, and determine a plurality of transmission parameters for an autonomous uplink transmission based on the total number of resource elements. The UE may transmit, to the base station, the uplink control information within the anchor resources to indicate the plurality of transmission parameters for the autonomous uplink transmission.

Abstract: Wireless communications systems and methods related to communicating in a shared communication medium with flexible scheduling are provided. A first wireless communication device communicates, with a second wireless communication device during a reservation period, a channel reservation request for a first transmission opportunity (TXOP) in a spectrum. The first wireless communication device communicates, with the second wireless communication device during a response period in response to the channel reservation request, a channel reservation response. The first wireless communication device communicates, with a third wireless communication device during a first time period between the reservation period and the response period, a first communication signal.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as a user equipment may receive control signaling that configures the communication device with a set of configured grant configurations. The communication device may receive, via a group control channel, group downlink control information (DCI) for a plurality of communication devices that includes the communication device. In some examples, the group control channel may be a group physical downlink control channel. The communication device may communicate a data transmission in accordance with a first configured grant configuration of the plurality of configured grant configurations based on a configuration indication in the group DCI indicating the first configured grant configuration.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may use a downlink control information (DCI) message to indicate timing resources to a user equipment (UE) for multiple downlink data repetitions in a slot. In a first implementation, the base station may indicate an explicit time domain resource allocation (TDRA) for one repetition in the TDRA field of the DCI, and the UE may determine implicit TDRAs for the other repetitions based on the explicit TDRA. In a second implementation, the base station may indicate a total TDRA for the full set of repetitions in the TDRA field, and the UE may divide the total TDRA into individual TDRAs for the repetitions. The UE may receive the downlink data repetitions based on determining the TDRAs and may transmit a feedback message in response based on a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook.

Abstract: Wireless communications systems and methods related to uplink control channel transmissions with user multiplexing and reference signal transmissions are provided. A first wireless communication device obtains an uplink control channel multiplex configuration. The first wireless communication device communicates, with a second wireless communication device, a grant indicating a plurality of resource blocks spaced apart from each other by at least one other resource block in a shared radio frequency band, the plurality of resource blocks scheduled for multiple wireless communication devices based on the uplink control channel multiplex configuration. The first wireless communication device communicates, with the second wireless communication device, a first uplink control channel signal in one or more of the plurality of resource blocks based on the uplink control channel multiplex configuration.

Abstract: Methods, systems, and devices for multiplexing code block group (CBG) level and transport block (TB) level feedback are described. An example method includes receiving a set of TBs, generating a bit sequence providing CBG-level feedback on a first subset of the TBs and TB-level feedback on at least a second subset of the TBs, and transmitting the bit sequence. Another example method includes transmitting a set of TBs, receiving a bit sequence providing CBG-level feedback on a first subset of the TBs and TB-level feedback on at least a second subset of the TBs, and retransmitting at least one CBG for each TB in the first subset of TBs and the second subset of TBs based at least in part on the bit sequence.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a coreset of time and frequency resources within a control region of a coreset bandwidth. In one aspect, the coreset bandwidth may be based on a minimum bandwidth configuration associated with one or more UEs in a set of UEs. The apparatus may also transmit a PDCCH as a single-carrier waveform via the coreset of time and frequency resources. In one aspect, the PDCCH may be transmitted to each UE in the set of UEs using the coreset bandwidth.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may multiplex reference signal (RS) transmissions for different antenna ports over a set of resource elements using a code division multiplexing (CDM) group spreading in a time dimension and a frequency dimension. The base station may transmit the RS transmissions over the set of resource elements based at least in part on the multiplexing to a user equipment (UE). The UE may demultiplex the RS transmissions based at least in part on a CDM group and may select at least one of the time dimension or the frequency dimension over which to demultiplex the RS transmissions based on a determination or other information.
