Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive an indication of a set of corresponding physical downlink control channel (PDCCH) candidates that includes at least a first PDCCH candidate included in a first control resource set (CORESET) and a corresponding second PDCCH candidate included in a second CORESET, wherein the first CORESET and the second CORESET have different transmission configuration indication (TCI) states; and selectively perform, based at least in part on a configuration, at least one of: independent decoding of the first PDCCH candidate, independent decoding of the second PDCCH candidate, or joint decoding of the first PDCCH candidate and the second PDCCH candidate. Numerous other aspects are provided.

Abstract: Techniques and apparatus for reporting channel state information (CSI) for unlicensed coordinated multipoint (CoMP) operations are provided. One technique includes determining, based on one or more conditions, for each of a plurality of base stations available for a coordinated multipoint (CoMP) transmission, whether the base station has transmitted a channel state information reference signal (CSI-RS) in unlicensed spectrum. CSI feedback is reported based on the determination.

Abstract: Aspects of the disclosure relate to a method and apparatus for receiving a joint transport block transmission. A user equipment (UE) receives a configuration message configuring the UE to receive a joint transport block (TB) transmission of data from a plurality of transmission points (TRPs). The UE determines a transport block size (TBS) for receiving the joint TB transmission, receives transport blocks corresponding to the joint TB transmission, each transport block from a respective one of the plurality of TRPs, combines the transport blocks when a size of each of the transport blocks is the determined TBS, and recovers the data based on the combined transport blocks. Other aspects, embodiments, and features are also claimed and described.

Abstract: A transmission opportunity (TO) allows a transmitting device, such as a base station to transmit up to a pre-determined TO duration. For new radio (NR), subcarrier spacing (SCS) is no longer fixed. This may limit a TO duration for a UE to a small portion of the allowed TO duration, for new radio (NR), a transport block (TB) takes up one slot. A method, apparatus, and computer-readable medium are disclosed extend a TB over more than one slot to maximize utilization of a TO duration, for improved resource utilization and service quality. A method, apparatus, and computer-readable medium implemented by a communication device are disclosed to receive a signaling message, to configure a flexible transport block (TB) to extend the TB over more than one slot. Then the communication device may receive a portion of the flexible TB, based on the received signaling message.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for aggregation level (AL) design for physical downlink control channel (PDCCH) transmissions. New aggregation levels may be used in an effort to improve the reliability for PDCCH transmissions.

Abstract: Apparatuses and methods are disclosed for determining a transport block size (TBS) as a function of various parameters without cyclic dependencies between the parameters and TBS. The disclosed function can determine a TBS in a single pass, and the determined TBS allows the use of code blocks with equal code block size (CBS) in a transport block segmentation process. The determined TBS can provide byte-aligned code block lengths and require no padding bits in a transport block.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to random access channel (RACH) procedures in deployments where a RACH transmission may be sent on different UL carriers. An exemplary method performed by a base station includes receiving a random access (RA) preamble on a first component carrier (CC) of a plurality of CCs including at least one uplink (UL) CC and at least one supplemental uplink (SUL) CC and transmitting a response to the RA preamble, wherein the response indicates the first CC.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. More particularly, aspects of the present disclosure provide multiplexing schemes which may be suited for the single carrier waveform. For example, some techniques and apparatuses described herein permit multiplexing of multiple, different data streams without destroying the single-carrier properties of the waveform. Additionally, or alternatively, some techniques and apparatuses described herein may provide unequal error protection, unequal bandwidth allocation, and/or the like as part of the multiplexing schemes. Examples of multiplexing schemes described herein include in-phase/quadrature (I/Q) multiplexing, superposition quadrature amplitude modulation (QAM) based at least in part on layered bit mapping, polarization division multiplexing of QAM with superposition coding, and frequency division multiplexing using UE-specific beams.
