Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for dynamically triggering or skipping channel state feedback (CSF). A method that may be performed by a user equipment (UE) includes receiving, from a network entity, a configuration indicating CSF reporting occasions, receiving a downlink (DL) transmission, and transmitting CSF on only some CSF reporting occasions after receiving the DL transmission when one or more trigger conditions are met. According to certain aspects, when one or more trigger conditions are not met, the UE skips at least some CSF reporting occasions.

Abstract: Aspects of the present disclosure provide techniques for multiplexing high priority uplink control information (UCI) and low priority UCI on a physical uplink control channel (PUCCH). A method includes determining a total number of resource blocks to transmit encoded UCI bits based on a quantized payload size of a second one or more encoded UCI bits of a second priority and a non-quantized payload size of a first one or more encoded UCI bits of a first priority. The method generally includes mapping the second one or more encoded UCI bits to a first number of resource elements associated with the quantized payload size and the first one or more encoded UCI bits to a second number of REs and transmitting the encoded UCI bits in a PUCCH in accordance with the mapping.

Abstract: Certain aspects of the present disclosure provide techniques for a hybrid automatic repeat request (HARQ) procedure for the random access channel (RACH) response message in a two-step RACH procedure. A method that may be performed by a user equipment (UE) includes sending a RACH message to a base station (BS) during a two-step RACH procedure. The RACH message includes a RACH preamble and a RACH payload. The UE monitors a RACH response message from the BS during a random access response (RAR) window. The UE transmits a retransmission of the RACH message, an acknowledgement (ACK) to the RACH response message, a negative acknowledgment (NACK) to the RACH response message, or does not transmit, to the BS based on whether a RACH response message carrying a success RAR or a fallback RAR, or no RACH response message, is received from the BS during the window.

Abstract: Techniques related to multiplexing uplink control information (UCI) onto a multi-transport block (TB) physical uplink shared channel (PUSCH) transmission are disclosed. Some aspects of the disclosure relate to devices and methods for wireless communication where a user equipment (UE) receives an uplink grant for a PUSCH transmission having a plurality of TBs, each being associated with a respective TB priority index. The UE then transmits the PUSCH including the plurality of TBs. The UE may further transmit a plurality of UCIs multiplexed with the PUSCH, where each UCI is associated with a respective UCI priority index. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a plurality of physical uplink control channel (PUCCH) repetitions of different lengths using vectors of orthogonal cover code (OCC) matrices that differ in size across two or more of the plurality of PUCCH repetitions. The UE may transmit the plurality of PUCCH repetitions. Numerous other aspects are provided.

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: 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: Methods, systems, and devices for wireless communications are described that support signaling for energy harvesting at a first device. In some examples, the first device may transmit, to a second device, an indication of one or more an energy conversion efficiency factors, power threshold parameters, power levels, battery power levels, or the like. Based on receiving the indication of the one or more of the characteristics, the second device may determine a radio frequency power for subsequent signaling. The second device may transmit a signal having the determined radio frequency power, and the first device may receive the signaling and convert at least a first portion of the radio frequency power to direct current (DC) power.

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.
