Abstract: Methods, systems, and devices are described for wireless communications that support transmitting channel state information (CSI) feedback utilizing flexible uplink control resources. A method may include determining a size of a frequency subband corresponding to components of a CSI feedback report based on configuration signaling or a size of allocated uplink control resources. A method may include encoding a CSI report into a single packet and transmitting the single packet over uplink control resources. A method may include encoding a first plurality of components of a CSI report in a first packet, encoding a second plurality of components of the CSI report in a second packet, and mapping the packets to uplink control resources. A method may include transmitting a first plurality of components of a CSI report on a first slot and a second plurality of components of the CSI report on one or more subsequent slots.

Abstract: A user equipment (UE) may be configured with a first set of indexed timing offsets for determining offsets between uplink grants and uplink data transmissions and a second set of indexed timing offsets for determining offsets between an aperiodic channel state information (CSI) trigger and transmission of an aperiodic CSI report. A UE may receive both an uplink grant for an uplink data transmission and an aperiodic CSI report trigger. The UE may determine a timing offset for transmission of both the uplink data transmission and the aperiodic CSI report. The timing offset may be based at least in part on the first set of indexed timing offsets, the second set of indexed timing offsets, or a third set of indexed timing offsets for joint transmission of uplink data and aperiodic CSI. The UE may transmit the uplink data transmission and the aperiodic CSI report according to the timing offset.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting a channel state information (CSI) report from a user equipment (UE). The CSI report may be a UE initiated CSI report or may be based on a downlink grant. The UE may determine to transmit the CSI report in response to a measurement of a CSI measurement resource or in response to a downlink grant requesting the CSI. The UE may determine a reserved uplink resource to carry the CSI based at least in part on configurations associated with the CSI report. The UE may transmit the CSI report on the determined uplink resource.

Abstract: A device may identify that an incremental redundancy hybrid automatic repeat request (IR-HARQ) scheme is used in association with sequential transmissions of an information bit vector to or from another wireless device, where each transmission in the scheme is associated with a resource size. The device may identify a mother code length for a polar code based at least in part on an aggregate resource size associated with the sequential transmissions. The device may identify an adjusted bit index set for the polar code based at least in part on the IR-HARQ scheme. The device may transmit (or receive), for each transmission of the information bit vector, a respective subset of encoded bits generated by mapping the information bit vector to a set of polarized bit channels of the polar code in accordance with the bit index set.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform channel state information (CSI) measurements on one or more reference signal transmissions received from a base station. Based on the CSI measurements, the UE may generate a CSI report, and the UE may transmit the CSI report to the base station. In some cases, the generated CSI report may include a first portion and a second portion. The first portion may indicate whether the second portion of the CSI report includes full-band CSI feedback or partial-band CSI feedback. The second portion may provide the CSI feedback for one or more identified sub-bands. In some cases, the second portion may include a sub-band index indicating the identified sub-bands. Additionally or alternatively, the second portion may include a bitmap indicating a correspondence between multiple CSI feedback values and multiple corresponding sub-band indexes.

Abstract: A user equipment (UE) may be configured with a first set of indexed timing offsets for determining offsets between uplink grants and uplink data transmissions and a second set of indexed timing offsets for determining offsets between an aperiodic channel state information (CSI) trigger and transmission of an aperiodic CSI report. A UE may receive both an uplink grant for an uplink data transmission and an aperiodic CSI report trigger. The UE may determine a timing offset for transmission of both the uplink data transmission and the aperiodic CSI report. The timing offset may be based at least in part on the first set of indexed timing offsets, the second set of indexed timing offsets, or a third set of indexed timing offsets for joint transmission of uplink data and aperiodic CSI. The UE may transmit the uplink data transmission and the aperiodic CSI report according to the timing offset.
