Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling identifying a configuration for reporting channel metrics for transport blocks that each include a plurality of code block group. The UE may receive a first transport block that includes a first plurality of code block groups. The UE may transmit a report indicating a channel metric for one or more code block groups of the first plurality of code block groups of the first transport block in accordance with the configuration for reporting channel metrics. In some cases, the UE may report a differential channel metric, based in part on a reference metric. Additionally or alternatively, the UE may report compressed feedback for a group CBGs.

Abstract: Aspects of the present disclosure relate to wireless communication systems configured to provide user equipment (UE)-specific slot structures based on the individual propagation delay experienced by each UE. In some examples, the duration of uplink transmissions for a particular UE within a slot may be configured based on the propagation delay between the base station and that particular UE. For example, the duration of an uplink burst and/or an uplink traffic transmission may be configured based on the propagation delay. In addition, a downlink burst within a slot may be configured for a particular UE on the propagation delay experienced by that UE. Downlink traffic transmissions may further be configured for the cell based on the maximum propagation delay experienced by the UEs in the cell.

Abstract: Methods, systems, and devices for wireless communication are described to support reducing conflicts with between scheduling request opportunities and downlink resources. A base station may configure a user equipment (UE) with a scheduling request periodicity and offset for identifying scheduling request opportunities. The UE and base station may apply the periodicity and the offset to a first subset of time periods of a set of multiple time periods, where the first subset of time periods may include scheduling request opportunities that do not overlap with resources allocated for downlink transmissions. Based on applying the offset and periodicity to the first subset of time periods, the UE may identify a scheduling request opportunity, in a first time period of the first subset, and may transmit a scheduling request to the base station via the scheduling request opportunity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling that indicates whether feedback for each of one or more downlink messages scheduled to be received at the UE is to be single-bit feedback or multi-bit feedback. The UE may monitor for the one or more downlink messages. The UE may generate, based at least in part on the monitoring for the one or more downlink messages, a codebook for reporting the feedback pertaining to each downlink message, the codebook supporting inclusion of both single-bit feedback and multi-bit feedback based at least in part on the signaling. The UE may transmit a feedback message that is based at least in part on the codebook.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support configurations for grouping feedback information within a codebook. A user equipment (UE) may support one or more types of feedback. In some cases, the UE may generate subsets of feedback information within the codebook based on each type of feedback, which may increase overhead. To reduce overhead, the UE may receive signaling that indicates a configuration for grouping feedback information within a codebook. The UE may receive downlink messages that may be associated with a same set of uplink resources for transmitting a feedback message. The UE may generate a codebook to include one or more groups of feedback information in accordance with the configuration and based on the downlink messages. The UE may transmit the feedback message based on the codebook and via the set of uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a first transmission of a first service type (e.g., enhanced mobile broadband (eMBB)) and a second transmission of a second service type (e.g., ultra-reliable low-latency communication (URLLC)). The UE may identify a feedback codebook size for the first service type. The UE may multiplex a first feedback codebook having the identified feedback codebook size and generated for the first transmission with a second feedback codebook generated for the second transmission. Multiplexing the first and second feedback codebooks may produce a multiplexed feedback codebook. In some cases, the UE may perform the multiplexing based on a feedback multiplexing condition being satisfied. The UE may transmit the multiplexed feedback codebook in a control channel (e.g., a physical uplink control channel (PUCCH)) or a shared data channel (e.g., a physical uplink shared channel (PUSCH)).

Abstract: Methods, systems, and devices for wireless communications are described. A method of wireless communication at a user equipment (UE) is described that may include receiving a data packet transmission over a wireless channel from a base station. The method may further include determining a set of intrinsic log likelihood ratios (LLRs) based at least in part on the data packet transmission and determining an accumulated capacity for the wireless channel based at least in part on the set of intrinsic LLRs. The method may also include determining a channel quality indicator index or a transmission rank for the wireless channel based at least in part on the accumulated capacity and transmitting a feedback message that indicates the channel quality indicator index or the transmission rank for the wireless channel to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive one or more messages scheduling a first uplink transmission over a first physical uplink control channel (PUCCH) resource on a first component carrier and a second uplink transmission over a second PUCCH resource on a second component carrier and, if the first PUCCH resource and the second PUCCH resource overlap in time, the UE 115 may transmit the first uplink transmission and the second uplink transmission using spatial relation information in accordance with a spatial relation configuration that is dedicated for selecting spatial relation information for simultaneous PUCCH transmissions on different component carriers. A network entity may configure the UE with spatial relation information for the overlapping PUCCH resources and the UE may select spatial relation information to use for the simultaneous uplink transmissions in accordance with the spatial relation configuration.

Abstract: Techniques and apparatus for transmitting control information to maintain hybrid automatic repeat request (HARQ) processes for multiple carriers in different frequency ranges, such as frequency range 1 (FR1) and frequency range 2 (FR2), in carrier aggregation scenarios are described. A first numerology of a first component carrier (CC) in FR1 and a second numerology of a second CC in FR2 are determined. A HARQ configuration that includes an indication of a set of physical uplink control channel (PUCCH) resources is determined. A number of symbols of the set of PUCCH resources is based on the first numerology and the second numerology. The HARQ configuration is transmitted to a user equipment (UE). HARQ feedback is transmitted on the first CC for data received on the second CC, using the set of PUCCH resources of the HARQ configuration.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a transmission of uplink control information (UCI) from a user equipment (UE) to a base station using uplink shared channel resources in the absence of other uplink shared channel data. Based in the UCI and uplink control parameters, the UE may determine an uplink power for transmission of the UCI based at least in part on a spectrum efficiency or a number of bits per resource element (BPRE) for the UCI.
