Abstract: Systems and methods configured to provide size matching of downlink control information (DCI) formats to restrict a number of DCI format sizes for a set of DCI formats for concurrent use are described, in accordance with embodiments of the present disclosure, size matching at least two DCI formats of a set of DCI formats to restrict a number of DCI format sizes for the set of DCI formats for concurrent use is implemented. Restrictions with respect to the number of DCI format sizes for the set of DCI formats may correspond both to a first number of DCI sizes parameter based on a total number of DCI format sizes per wireless communication slot, and to a second number of DCI sizes parameter based on a total number of DCI format sizes for DCI formats used to carry DCI payload encoded using an identifier per wireless communication slot.

Abstract: Certain aspects of the present disclosure provide techniques for slot aggregation in new radio (NR) systems. A method of wireless communication by a user equipment (UE) includes receiving radio resource control (RRC) signaling providing a semi-static configuration for transmission and/or reception of a repeated transport block (TB) and/or a different TB in each of a plurality of aggregated slots. The UE transmits or receives the TBs in the plurality of aggregated slots based on the semi-static configuration. Another method is provided in which the UE transmits and/or receives a demodulation reference signal (DMRS) in each of a plurality of aggregated slots, each DMRS associated with a repeated TB or a different TB in the slot. The UE determines, based on received signaling, whether the DMRS use a same precoder or a different precoder and modulates and/or demodulates the TBs in the plurality of aggregated slots based on the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a remaining minimum system information control resource set (RMSI CORESET) monitoring configuration based at least in part on information received by the UE in a first frame; and monitor, during a second frame and based at least in part on the RMSI CORESET monitoring configuration, for an RMSI CORESET based at least in part on a synchronization signal block (SSB), associated with the RMSI CORESET, that is received in the first frame. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a bandwidth part switch from a first bandwidth part to a second bandwidth part. The user equipment may transition from the first bandwidth part to the second bandwidth part after determining the bandwidth part switch and based at least in part on a critical section defined for the transitioning from the first bandwidth part to the second bandwidth part. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a reference signal preemption scheme associated with one or more reference signal resources being preempted for priority transmissions during a time period. The UE may determine that resources of one or more reference signals have been preempted during the time period and in accordance with the reference signal preemption scheme. The UE may implement a reference signal preemption response scheme that is selected based at least in part on the resources of the one or more reference signals being preempted.

Abstract: Methods, systems, and devices for wireless communications are described. A network device such as a next generation (gNB) may identify control information for transmission on a downlink control channel e.g., a physical downlink control channel (PDCCH). The network device may identify a candidate set of decoding candidates to which the control information is able to be mapped. In some examples, each decoding candidate may include one or more control channel elements (CCEs). The network device may select, from the candidate set of decoding candidates, an actual set of decoding candidates to which the control information is to actually be mapped, and map the control information into the actual set of decoding candidates. Upon decoding the control information, the network device may transmit the control information within a search space including the actual set of decoding candidates to a user equipment (UE).

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes selecting between a first frequency range and a second frequency range to transmit a physical channel, the second frequency range being higher than the first frequency range, and jointly encoding at least two fields of the physical channel based at least in part on the selected frequency range. In some cases, the method includes selecting between a first frequency range and a second frequency range to transmit a physical channel. In some cases, the second frequency range is higher than the first frequency range. The method may further include adjusting a quantity of bits associated with a field of the physical channel based at least in part on the selected frequency range.

Abstract: Techniques are described for signaling a downlink bandwidth part (BWP) switching event and an aperiodic channel state information (A-CSI) request in a paired spectrum environment. The base station may transmit uplink scheduling downlink control information (DCI) to a user equipment (UE) that includes the A-CSI request and an identifier for the downlink BWP of the downlink BWP switching event. After receiving the A-CSI request and the downlink BWP, the UE may perform one or more CSI measurements using the downlink BWP. The UE may use physical uplink shared channel (PUSCH) resources associated with the uplink scheduling DCI to transmit the CSI report to the base station. Using these techniques, the base station may be configured to indicate that a downlink BWP switching event is to occur and allocate PUSCH resources to the UE to be used to transmit the CSI report associated with the downlink BWP switching event.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication, with focus on reducing problems of downlink control information, DCI, size ambiguity when polar coding is used. In some aspects, a user equipment may receive a communication that includes DCI, wherein a size of the DCI affects a cyclic redundancy check, CRC, value associated with the communication; and determine the DCI or the size of the DCI based at least in part on the CRC value. Numerous other aspects are provided.
