A method for improving transmission efficiency of physical layer attributes in a wireless communication system is proposed, and the method comprises the following steps of: (a) defining one or more sets of physical layer channel basic attributes that must be supported, and each set being respectively represented by a value of a domain of attributes, that is, a value of Profile; (b) a transmitting apparatus sending a physical layer channel description information, wherein the value of Profile is used to represent the physical layer channel basic attributes supported by the apparatus; (c) after receiving the channel description information, based on the value of Profile within the information, a receiving apparatus judging whether a set of physical layer channel basic attributes corresponding to the value is supported.
