Abstract: Methods, systems, and devices for wireless communications are described. A first device may obtain information indicative of a configuration to provide code block group (CBG)-based feedback for one or more semi-persistent scheduling (SPS) communications scheduled for the first device. The first device may then monitor for the one or more SPS communications in one or more CBGs of a TB in accordance with one or more SPS communication configurations. Based on the monitoring of the semi-persistent scheduling communications, the first device may generate one or more feedback bits associated with the one or more SPS communications, and may communicate, with a second device, the one or more feedback bits associated with the one or more SPS communications in accordance with the configuration to provide CBG-based feedback.

Abstract: Aspects relate to a scheduling entity allocating a group of scheduled entities with resources that define an uplink channel, transmitting an uplink cancellation indication (ULCI) to the group of scheduled entities identifying at least some resource blocks and OFDM symbols in the allocated resources that are canceled for use as the uplink channel, obtaining a processing time of a scheduled entity, where the scheduled entity may use the processing time to process a command from the scheduling entity, the processing time is based on a reference subcarrier spacing (SCS) that may be less than or equal to a downlink SCS of a downlink channel carrying the ULCI, and waiting at least the processing time before utilizing the at least some resource blocks and OFDM symbols for a purpose other than the uplink channel. A scheduled entity receives the ULCI and may process the ULCI after expiry of the processing time.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may provide a feedback message to a base station that includes a feedback report that indicates successful or unsuccessful receipt of multiple downlink transmissions, and also includes an indication of a number of unsuccessful receipts that are due to unsuccessful receipt of data channel communications. The indication of the number of unsuccessful receipts of data channel transmissions may be provided as a binary representation of the total number, or may be provided as a quantized value in which each quantized point is associated with a certain number of unsuccessfully received data channel transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may receive one or more signals indicating first and second uplink messages that at least partially overlap in time. The first uplink message may be associated with a first set of parameters and a first quantity of antenna ports and the second uplink message may be associated with a second set of parameters and a second quantity of antenna ports. The UE may transmit the first and second uplink messages using a third set of scheduling parameters based on a sum of the first quantity and the second quantity of antenna ports being greater than a quantity of available radio frequency (RF) chains at the UE. The third set of scheduling parameters may be associated with a third quantity of antenna ports that is less than the sum of the first and second quantities.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for TDRA-based HARQ-ACK feedback generation. In aspects, a UE and a base station may determine that at least one TDRA candidate of a set of TDRA candidates for a PDSCH transmitted from a base station has more than one possible location within a slot. Based on the determination that the at least one TDRA candidate has more than one possible location within the slot, the UE may generate and transmit corresponding HARQ-ACK feedback to the base station, which may decode the HARQ-ACK feedback.

Abstract: Methods, systems, and devices for wireless communications are described. PAPR may be relevant to managing transmitter power, receiver sensitivity, or both, and transmissions of a particular device may consider various PAPR reduction strategies to manage transmission power at the device. However, relay devices may be configured to forward communications from multiple transmitting devices, and PAPR may not be considered for aggregate signaling via such a relay device. In some examples of the described PAPR management techniques, assisting transmitters may be configured to transmit PAPR reduction signaling that may be received by a relay device, such that an aggregated signal that is received and forwarded by the relay device may have lower PAPR. Additionally, or alternatively, in some examples of the described PAPR management techniques, a relay device itself may inject PAPR reduction signaling into a received signal to reduce PAPR of a transmission by the relay device.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for priority based decisions regarding when to cancel or maintain configured transmissions that overlap with dynamically scheduled transmissions. An example method performed by a user equipment (UE) generally includes determining that a configured transmission overlaps in time with a dynamically scheduled transmission, and deciding whether to cancel or maintain the configured transmission based on a priority of at least one of the configured transmission or an uplink transmission associated with the dynamically scheduled transmission when the time between an end of a downlink control information (DCI) that scheduled the dynamically scheduled transmission and a start of the configured transmission is greater than a threshold processing time.

Abstract: Aspects are provided which allow a UE to provide a CSI report including an expiration time to a base station to reduce the risk of improper scheduling decisions at the base station based on outdated CSI reports. The UE obtains a channel measurement signal from the base station. The UE identifies CSI based on the channel measurement signal and provides a CSI report to the base station including the CSI. The CSI report further includes an expiration time for the CSI report. The base station obtains the CSI report from the UE including the expiration time for the CSI report, and the base station processes downlink data for transmission based on the expiration time in the CSI report.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE, a capability message indicating that the second UE is capable of processing one or more types of modulated waveforms. The first UE may encode a set of orthogonal frequency division multiplexing (OFDM) symbols with a first set of data for an uplink transmission to a network entity via a communication link between the first UE and the network entity, and may modulate the set of encoded OFDM symbols with a second set of data for the second UE according to a type of the one or more types of modulated waveforms capable of being processed by the second UE. The first UE may transmit and the second UE may monitor for the modulated set of encoded OFDM symbols via the communication link.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may use a downlink control information (DCI) message to indicate timing resources to a user equipment (UE) for multiple downlink data repetitions in a slot. In a first implementation, the base station may indicate an explicit time domain resource allocation (TDRA) for one repetition in the TDRA field of the DCI, and the UE may determine implicit TDRAs for the other repetitions based on the explicit TDRA. In a second implementation, the base station may indicate a total TDRA for the full set of repetitions in the TDRA field, and the UE may divide the total TDRA into individual TDRAs for the repetitions. The UE may receive the downlink data repetitions based on determining the TDRAs and may transmit a feedback message in response based on a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook.
