A METHOD AND DEVICE FOR HANDLING DIFFERENT DCI MESSAGES IN A WIRELESS NETWORK NODE OF A CELLULAR COMMUNICATION SYSTEM PROVIDING MULTIPLE BANDWIDTHS

摘要

The disclosure relates to a method of transmitting downlink control signalling in a wireless network node of a cellular communication system, when the node provides more than one transmission bandwidth. In particular it relates to a method in a wireless network node (10) of a cellular communication system for transmitting downlink control signalling (10) to at least one wireless device (20). The wireless network node (10) operates over at least two different transmission bandwidths (201, 202). The method comprises transmitting (S1) information about at least one of the transmission bandwidths (201, 202) to wireless devices (20) in the cellular communication system, configuring (S2) properties of at least one downlink control message, to represent one of the at least two different transmission bandwidths and transmitting (S3) the at least one downlink control message to the at least one wireless device in the cellular communication system. The disclosure further relates to a wireless device as well as to a method of receiving downlink control signalling in a wireless device. The method comprises retrieving (S11) information about the available transmission bandwidths in the cellular communication system, receiving (S12) at least one downlink control message from the cellular communication system and determining (S13) based on properties of the at least one received downlink control message, which of the available transmission bandwidths is represented by the at least one downlink control message.
