    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of control resource sets for reduced bandwidths. In a first aspect, a method of wireless communication includes receiving, from a base station at a user equipment (UE) having a first type, a master information block (MIB) within a physical broadcast channel (PBCH). The MIB includes CORESET size information and search space information for devices having a second type. The method also includes selecting a CORESET size from a plurality of preconfigured CORESET sizes based on a subcarrier spacing used to communicate with the base station. The method further includes monitoring a set of time and frequency resources to receive a message from the base station. The set of time and frequency resources has the selected CORESET size. Other aspects and features are also claimed and described.

    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: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for channel state information (CSI) report structure for dynamic antenna port adaptation. In some aspects, a user equipment (UE) and a network entity may support a CSI report configuration according to which the UE may include a respective set of CSI parameters for each of multiple codebooks. For example, the UE may compute a respective set of CSI parameters for each of multiple codebooks in accordance with a CSI report configuration and may transmit a CSI report including the respective sets of CSI parameters for each of the multiple codebooks. The network entity may use the respective sets of CSI parameters for each of the multiple codebooks to inform a dynamic antenna panel configuration update at the network entity.
