Abstract: Systems, devices, media, and methods are presented for throttling (i.e., adjusting) the workload of an application (e.g., number of task requests) in order to improve processor core usage within a heterogeneous multiprocessor system. When high-performance processing is beneficial to the application, the number of task requests may be increased in order to have high-performance processor cores within the heterogeneous multiprocessor system core processor perform the tasks. On the other hand, when high-performance processing is not beneficial, the number of task requests may be decreased in order to have low-performance processor cores within the heterogeneous multiprocessor system perform the tasks. Processor core usage is monitored, and the number of tasks being performed are adjusted to match the processor core usage to a target processor core usage for functions the application is performing.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, wireless devices may encode and decode transmissions using polar codes. A transmitting device may encode a payload based on a selected payload size. For example, the transmitting device may construct a bit vector including payload bits, parity bits, frozen bits, or some combination of these, and may modify the bits or the order of the bits based on the selected payload size. The device may generate a polar-encoded codeword based on this bit vector, and may transmit the polar-encoded codeword to a receiving device. The receiving device may blind decode the polar-encoded codeword, and may determine the correct payload size based on the decoded bit vector. For example, the device may perform decoding or may check decoded bits based on a payload size hypothesis, where the decoding may fail for any incorrect payload size hypothesis.

Abstract: A device may identify that an incremental redundancy hybrid automatic repeat request (IR-HARQ) scheme is used in association with sequential transmissions of an information bit vector to or from another wireless device, where each transmission in the scheme is associated with a resource size. The device may identify a mother code length for a polar code based at least in part on an aggregate resource size associated with the sequential transmissions. The device may identify an adjusted bit index set for the polar code based at least in part on the IR-HARQ scheme. The device may transmit (or receive), for each transmission of the information bit vector, a respective subset of encoded bits generated by mapping the information bit vector to a set of polarized bit channels of the polar code in accordance with the bit index set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may perform a first polar code encoding process on a first transmission of a hybrid automatic repeat request (HARQ) process; generate a second transmission of the HARQ process by relocating a portion of bits in less reliable positions of the first transmission to more reliable positions of the second transmission of the HARQ process, wherein the less reliable positions and the more reliable positions are evaluated based at least in part on a channel transform, wherein the channel transform is based at least in part on the first transmission, the second transmission, the first polar encoding process and a second polar encoding process associated with the second transmission; and transmit the second transmission of the HARQ process. Numerous other aspects are provided.
