Abstract: Various solutions for low-power wake-up signal (LP-WUS) monitoring with respect to user equipment and network node in mobile communications are described. An apparatus may receive a configuration from a network node. The apparatus may comprise a main radio (MR) and a lower-power wake-up radio (LP-WUR). The apparatus may determine whether to activate or deactivate a low-power wake-up signal (LP-WUS) monitoring by the LP-WUR according to at least one pre-configured condition in the configuration. The apparatus may receive an LP-WUS from the network node via the LP-WUR in an event that the LP-WUS monitoring is activated.

Abstract: Examples pertaining to re-transmission cyclic redundancy check (CRC) for polar coding incremental-redundancy hybrid automatic repeat request (IR-HARQ) are described. An apparatus (e.g., UE) encodes a plurality of information bits using a polar code to generate a polar code block (CB). The apparatus performs one or more transmissions of the polar CB using hybrid automatic repeat request (HARQ) by performing an initial transmission of the polar CB and performing a re-transmission of the polar CB with a re-transmission cyclic redundancy check (ReTX CRC).
