Abstract: A UE may be configured to determine a size of the TB for transmission to a base station based on signaling received from the base station for configuration of at least one of a scale factor or a slot aggregation factor associated with size of the TB. The UE may be further configured to transmit, to the base station, information on the TB in at least one slot, the TB being of the determined size. The base station may be configured to transmit, to the UE, the signaling for configuration of at least one of a scale factor or a slot aggregation factor associated with a size of the TB to be used by the UE for transmission. The base station may be further configured to receive, from the UE, information on at least one TB having a size that is based on at least one of the scale factor or the slot aggregation factor.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a system information block (SIB) indicating a plurality of subband configurations. The UE may identify, based at least in part on one or more of the plurality of subband configurations, one or more uplink subbands in a time division duplexing (TDD) component carrier and one or more downlink subbands in the TDD component carrier. The one or more uplink subbands and the one or more downlink subbands may be frequency division duplexed within the TDD component carrier. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for cancelling transmissions during handover operations. In one aspect, a user equipment (UE) can cancel at least a portion of a first uplink transmission where the first uplink transmission overlaps with a second uplink transmission scheduled by a target cell in a dual active protocol stack (DAPS)-based handover (HO). In another aspect, a network can receive, from the UE, a capability indicating whether cancelling uplink transmission from a source cell in DAPS-based HO is supported, and the network can schedule an uplink transmission for the UE during the DAPS-based HO to the target cell based on the capability.

Abstract: A method of wireless communication at a transmitting device includes adding parity check bits to a set of information bits. The method also includes generating a non-coherent transmission signal by mapping the parity check bits and the set of information bits into a sequence of complex symbols. Further, the method may include transmitting the non-coherent transmission signal to a receiving device. A method of wireless communication at a receiving device includes receiving, from a transmitting device, a non-coherent signal having at least one segment. Each segment comprises a sequence of complex symbols corresponding to information bits and parity check bits. The method also includes jointly detecting the sequences from each segment of the received non-coherent signal by using the parity check bits.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for interference measurement and reporting by a UE. The interference measurement can be self-initiated by the UE or based on a request received from a BS. To measure the interference, the UE transmits a first signal in UL resources to a first BS concurrently with receiving a second signal in DL resources from one of the first BS or a second BS. The received second signal includes interference associated with the transmitted first signal. Based on the received second signal, the UE determines a level of the interference that is associated with the transmitted first signal. Information associated with the level of the interference is then transmitted to the first BS, such as an indication of a guard band that is to be incorporated between the UL resources and the DL resources.
