DECIDING WHETHER TO SEND UPLINK CONTROL SIGNALING BASED ON THE ACTIVE TIME STATUS OF A USER EQUIPMENT CONFIGURED WITH DISCONTINUOUS RECEPTION (DRX)

摘要

A method in a user equipment for deciding whether or not to send an uplink transmission (ie. Channel State Information, CSI, and/or Sounding Reference Signal, SRS) to a radio access network node (Node B) is provided. The user equipment and radio access network node (Node B) are comprised in a communications network. The user equipment is configured with Discontinuous Reception, DRX, to be in active time or not be in active time. The user equipment decides (201) whether or not to send the uplink transmission at a transmission time t, based on whether the user equipment was in active time or not at a predefined earlier time instance relative to the transmission time t.
