Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determining that a first physical downlink control channel (PDCCH) candidate and a second PDCCH candidate in a control resource set (CORESET) are aligned with each other, wherein the first PDCCH candidate is a common search space (CSS) candidate and the second PDCCH candidate is a UE-specific search space (UESS) candidate; and decode downlink control information in accordance with a selected candidate, of the CSS candidate or the UESS candidate, based at least in part on a rule indicating whether the time-domain resource allocation is to be determined in accordance with the CSS candidate or the UESS candidate. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.

Abstract: Methods, systems, and devices are described for handling transmissions or channels in wireless communications that collide with one another. The described techniques relate to handling the collision between multiple overlapping channels (e.g., two or more channels of the same priority). For example, a collision resolution configuration may include resolving the collisions among the channels of the same priority first (e.g., feedback information transmissions first, and then control information), among the channels of the same service type first (e.g., normal channels first, and then low latency channel(s)), or across all of the channels of all priorities at once. Collisions may be resolved by dropping or rescheduling overlapping information from the lower priority transmission(s) or channel(s) in consideration of the higher priority transmission(s) or channel(s), or by multiplexing or piggybacking overlapping information from a first priority transmission(s) or channel(s) with a second priority transmission(s) or channel(s).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may cyclically shift, based at least in part on a cyclic shift index selected from a group of cyclic shift indexes, a demodulation reference signal (DMRS) sequence. The UE may transmit, on a physical uplink control channel (PUCCH), a DMRS corresponding to the shifted DMRS sequence with pi/2 binary phase shift key (BPSK) modulation. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.

Abstract: The present disclosure relates to methods and devices for communication which may include a user equipment (UE) and a base station. In one aspect, the UE may receive a trigger to measure an uplink Aperiodic Channel State Information Reference Signal (A-CSI-RS). The UE may also receive an allocation of a first resource for an uplink shared channel. Additionally, the UE can receive at least one indication for an A-CSI report to comprise a null A-CSI report. Moreover, the UE can determine whether to alter another uplink transmission. In some aspects, this determination can be based, at least in part, on whether the first resource allocated for the uplink channel overlaps in time with a second resource for the other uplink transmission.

Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may identify a set of allocated resource blocks and a number of the allocated resource blocks. The transmitting device may determine a bit sequence length corresponding to the number of allocated resource blocks. The transmitting device may generate a reference signal based on a bit sequence having the bit sequence length and transmit the reference signal within the allocated resource blocks. The transmitting device may modulate the bit sequence using a π/2 binary phase shift keying modulation scheme. The transmitting device may modulate a data bit sequence using the same modulation scheme to generate a modulated data bit sequence, where a peak to average power ratio (PAPR) of tones transporting the modulated data bit sequence satisfies a PAPR threshold and a PAPR of tones transporting the reference signal also satisfies the PAPR threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a first sub-slot periodicity for downlink semi-persistent scheduling (SPS). The UE may receive a plurality of transmissions according to the first sub-slot periodicity in a first slot, wherein the first sub-slot periodicity enables receiving the plurality of transmissions within a single slot. The UE may transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) information in a second slot, wherein the second slot includes a plurality of physical uplink control channels (PUCCHs) with a second sub-slot periodicity, and wherein the HARQ-ACK information is associated with the plurality of transmissions. Numerous other aspects are provided.
