Abstract: Aspects of the disclosure are directed to processor prefetching. In accordance with one aspect, processor prefetching includes determining if an exposed latency parameter is greater than zero; determining if a loop is present in a program code; determining if access overlap across fibers is true; and performing one of the following: a) insert a prefetch every quantity K fibers at a prefetch distance D; b) insert a prefetch every quantity K fibers with a maximum of quantity N iterations; or c) insert a prefetch per fiber with a maximum of quantity N iterations ahead; and wherein, the prefetch distance D is equal to an exposed latency parameter divided by an average instruction latency parameter, the quantity K is equal to a cache line size divided by a per fiber access size, and the quantity N is equal to an exposed latency parameter divided by an average iteration latency parameter.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a network entity may output, and a user equipment (UE) may receive, a first control message identifying a first discontinuous reception (DRX) cycle and a second, different DRX cycle for the UE to use, the first and second DRX cycles having a first and second active duration, respectively. The network entity may also output a second control message identifying periodic resources for the UE to use to monitor for a periodic signal, the periodic resources being outside at least the first active duration. The UE may monitor for, and the network entity may output, based on the periodic resources being outside the first active duration, the periodic signal during the first active duration based on updating the first active duration, updating the periodic resources, or both.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE may receive signaling configuring the UE with first and second sounding reference signal (SRS) resource sets. The UE may receive a first downlink control information (DCI) that schedules a first physical uplink shared channel (PUSCH) and indicates a first sounding reference signal (SRS) resource indicator (SRI) value, and a second DCI that schedules a second PUSCH and indicates a second SRI value. The UE may determine SRS resources indicated by the first and second SRI values based on an association between control resource set (CORESET) pool index values and the first and second SRS resource sets. The UE may transmit the first PUSCH indicated by the first SRI value and the second PUSCH indicated by the second SRI value, in accordance with the determination.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from two or more transmitters, two or more sidelink control informations (SCIs) that schedule channel occupancy time (COT) resources for the two or more transmitters. The receiver may transmit, to a transmitter of the two or more transmitters, an acknowledgement or negative acknowledgement (A/N) feedback via a mini-slot carrying a physical sidelink feedback channel (PSFCH) or sidelink feedback information (SLFI) with SCI. The A/N feedback may be transmitted before a listen-before-talk (LBT) and physical sidelink shared channel (PSSCH) transmission. The receiver may receive, from the transmitter using a COT resource, the PSSCH transmission based at least in part on the A/N feedback. The LBT and the PSSCH transmission may be adjustable at the transmitter based at least in part on the A/N feedback. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission power for an uplink shared channel communication based at least in part on at least one of a code rate parameter, a block length parameter, or a target block error rate parameter associated with the uplink shared channel communication. In some aspects, the user equipment may transmit the uplink shared channel communication using the transmission power based at least in part on determining the transmission power. Numerous other aspects are provided.

Abstract: The present disclosure relates to methods and devices for wireless communication at a wireless device of a wireless wearable device. In one aspect, the wireless device may transmit a first report based on one of a location of the wireless wearable device, a time period, or reception of a user-controlled indication to transmit the first report. The wireless device may also receive, based on the transmitted first report, a configuration to switch from a first mode to a second mode. In some aspects, the configuration can include at least one parameter associated with a power savings at the wireless wearable device while in the second mode. Additionally, the wireless device can operate based on the at least one parameter while in the second mode.

Abstract: Certain aspects of the present disclosure provide techniques for a user equipment (UE) to transmit assistance information to request changes to discontinuous reception (DRX) parameters to improve performance of the UE and its connection to a wireless network. A method that may be performed by a user equipment (UE) includes detecting one or more conditions; and transmitting, in response to the detection, a request to change a connected mode discontinuous reception (CDRX) configuration to a first network.
