Abstract: Methods, systems, and devices for wireless communications are described. A base station of a wireless communications system may transmit, to a user equipment (UE), a configuration message that indicates a transmission time interval (TTI) format for a plurality of TTIs. At least one format for the plurality of TTIs includes uplink resources and downlink resources separated in the frequency domain, which may be an example of a subband full duplex (SBFD) slot. Since the pattern may include some transitions between uplink and downlink resources, one or more gap periods (e.g., time gaps) may be positioned between such resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine whether to perform a simplified uplink control information (UCI) multiplexing procedure or select an overlapping uplink channel having the highest priority and drop the remaining overlapping uplink channels. The UE may determine that a first symbol period of the physical uplink scheduled channel (PUSCH) is aligned with a first symbol period of the physical uplink control channel (PUCCH) and the UE may multiplex UCI with an uplink data transmission. The UE may transmit the multiplexed UCI and uplink data on the PUSCH and drop the PUCCH. The UE may perform UCI multiplexing for overlapping PUCCH and PUSCH, located on the same component carrier (CC). The UE may refrain from performing UCI multiplexing if the PUSCH and the PUCCH are located on different CCs, and may simultaneously transmit UCI and uplink data over the different CCs.

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 a downlink control message from a base station scheduling multiple downlink messages and indicating a first offset for communicating a first feedback message of multiple feedback messages including feedback information for the multiple downlink messages. The UE may additionally receive, from the base station, a second offset for communicating the remaining feedback messages of the multiple feedback messages after communicating the first feedback message. The UE may transmit the first feedback message a quantity of resources equal to the first offset after receiving a first downlink message. The UE may then transmit the remaining feedback messages a quantity of resources equal to the second offset after transmitting the first feedback message. Each of the feedback messages may include feedback information for one downlink message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration signaling indicating a parameter for generating a plurality of first orthogonal matrices, wherein the plurality of first orthogonal matrices are based at least in part on a second orthogonal matrix, and wherein a size of the second orthogonal matrix is based at least in part on a number of one or more time periods configured for conveying a payload and a number of one or more frequency tones configured for conveying the payload. The UE may generate a plurality of codebooks corresponding to the plurality of first orthogonal matrices. The UE may transmit a first portion the payload using a first sequence from a first codebook of the plurality of codebooks and a second portion of the payload using a second codebook of the plurality of codebooks.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.
