Abstract

The present invention provides a method and apparatus for wireless communication. [Solution] A method for wireless communication in a user device (UE) 115-a, wherein the UE receives an activation message from a network device 105-a for one of a plurality of bandwidth portions configured for the UE, monitors downlink permissions 215 for receiving one or more downlink signals within the active bandwidth portion while operating within the bandwidth portion, and if it fails to detect one or more downlink permissions from the network device while operating within the bandwidth portion, adjusts the number of active receivers in the UE based on whether one or more downlink permissions have been detected.
