Abstract: Embodiments of this application provide a channel encoding method for use by a communication device. The communication device obtains a quantity K of information bits, and determines a load size of a channel for transmitting the K information bits. The load size of the channel is N bits, where N?K, N=2n, and n is a positive integer. The communication device performs a polar encoding process on the K information bits, to obtain a polar code sequence that includes N bits. The N-bit polar code sequence is transmitted using the channel, without rate matching. Because a quantity of coded bits obtained after the polar encoding is equal to a load size of a channel, no rate matching process is required. This reduces encoding overheads of a channel. Complexity and latency of channel encoding are greatly reduced, and performance loss associated with the rate matching operation is avoided.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems support user equipment (UEs) achieving power savings by operating in a connected discontinuous reception (C-DRX) mode. The systems may additionally utilize wakeup signals for further power savings at a UE. For example, a UE may be configured with a wakeup signal resource configuration (e.g., a first search space configuration) for monitoring for wakeup signals while operating in a low power mode. This first search space configuration may be different from a second search space configuration for the UE operating in an active mode. When in a low power mode, the UE may monitor for wakeup signals according to the wakeup signal resource configuration. If the UE receives a wakeup signal in a wakeup signal resource defined by the configuration, the UE may initiate a wakeup procedure and transition to the active mode for data transmission and reception.
