  • Publication number: 20240032041
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adjust resources (e.g., time resources, frequency resources) used to transmit repetitions of uplink control information (UCI) over a physical uplink control channel (PUCCH). The UE may adjust two parameters corresponding to different scales (e.g., levels) of adjustment, where a first parameter corresponds to a number of repetitions of a PUCCH resource and a second parameter corresponds to a number of slots within each PUCCH repetition. The UE may adjust the resources based on the first parameter, the second parameter, a size of UCI, a maximum coding rate, or some combination thereof, such that the PUCCH resources carrying UCI satisfy the maximum code rate and UCI size.

  • Publication number: 20240008035
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may convey uplink control information (UCI) to a base station using a multi-slot or single slot uplink channels. In some cases, however, transmissions scheduled on a first set of resources allocated for multi-slot transmission of a first uplink channel may overlap with one or more slots of a second set of resources allocated for multi-slot transmission of a second uplink control channel. Accordingly, the UE may employ a number of different techniques to transmit the UCI. In a first case, the UE may map the UCI to at least one of the overlapping slots of the first uplink channel. In a second case, the UE may drop the second uplink channel which carries the UCI. In a third case, and the UE may map the UCI to an overlapping slot of the second uplink channel.

  • Patent number: 11863272
    Abstract: The described techniques relate to improved methods, systems, devices, or apparatuses that support channel state information feedback for semi-open-loop and open-loop schemes. The described techniques provide for a user equipment (UE) to determine an open-loop, semi-open-loop, or closed-loop transmission scheme for deriving channel quality information (CQI). In the case of determined open-loop transmission scheme, the UE may select a transmission scheme corresponding to a time offset value and a precoder cycling granularity value. The UE may determine one or more of a time offset value, a precoder cycling granularity value, and a precoding matrix indicator (PMI) for a channel state information (CSI) report, and generate CQI accordingly. Additionally, the UE may include the determined values in the CSI report to indicate the transmission scheme used for the CQI derivation. Based on the CQI, the base station can then determine the transmission scheme and perform link adaption accordingly.

  • Patent number: 11855776
    Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.
