Abstract: Provided are a method, a user equipment, a device and a recording medium in which: resource allocation information associated with a plurality of symbols is received; symbols which cannot be used for uplink transmission among the plurality of symbols are determined on the basis of the resource allocation information; and the uplink transmission is performed in at least one of the remaining symbols from the plurality of symbols excluding the symbols which cannot be used. The symbols which cannot be used comprise a symbol (DL symbol) in which a slot format is instructed as downlink (DL) and K non-DL symbols immediately after the DL symbol among the plurality of symbols. Each of the K non-DL symbols is a symbol in which a slot format is not instructed as DL, and K is an integer greater than 0.

Abstract: One disclosure in the present specification presents a method for a wireless device to receive a paging message. The method may comprise: a step of deciding a wake up signal occasion (WUSO) window for attempting to receive a wake up signal (WUS); and a step of monitoring a downlink control channel during a paging window so as to attempt to receive a paging message, if the WUS is received within the decided WUSO window. Here, the WUSO window may be decided according to a duration size and offset.
