10 . The method of claim 7 , wherein determining the pre-empted wireless resource comprises:

determining the pre-empted wireless resource based on a reference wireless resource, wherein the reference wireless resource comprises M*N resource units formed by M divisions in time domain and N divisions in frequency domain, M and N being non-negative integers, and wherein the pre-empted wireless resource comprises a subset of the M*N resource units of the reference wireless resource.

11 . A computer program product comprising a non-transitory computer-readable program medium with computer code stored thereupon, the computer code, when executed by one or more processors, causing the one or more processors to implement a method claim 1 .

12 . A method performed by a wireless communication node in a wireless network, comprising:

sending a configuration message comprising information associated with a wireless resource to a wireless terminal in the wireless network, the information being associated with data reception or data transmission by the wireless terminal; and

composing a message indicating an update to the wireless resource or a transmission parameter associated with the wireless resource based on a type of the update, the message being configured to cause the wireless terminal to determine the type of the update among a plurality of types prior to parsing the message, the update instructing the wireless terminal to transmit or receive data or to skip transmitting or receiving data using the wireless resource based on the update,

wherein the plurality of types of the update comprises:

the wireless resource, or a downlink transmission associated with the wireless resource, or an uplink transmission associated with the wireless resource being canceled;

the wireless resource being partially pre-empted;

a transmission power of the uplink transmission associated with the wireless resource being adjusted; and
