A wireless telecommunications system comprising a plurality of terminal devices operable to communicate with a base station via respective network nodes, wherein the plurality of terminal devices comprises a first group of terminal devices operable to communicate with the base station via a first network node and a second group of terminal devices operable to communicate with the base station via a second network node, wherein each of the first and second groups of terminal devices are synchronised to communicate with the first and second network nodes, respectively, in a discontinuous mode comprising a repeating signalling cycle, the repeating signalling cycle comprising a first wake period and a second wake period; wherein: the first wake period is a first portion of the repeating signalling cycle and the start of the first wake period is defined by a first offset value relative to the start of the repeating signalling cycle; the second wake period is a second portion of the repeating signalling cycle and the start of the second wake period is defined by a second offset value relative to the start of the repeating signalling cycle, the second offset value being different to the first offset value; each terminal device in the first group of terminal devices is operable to exchange predetermined signalling with the first network node during the first wake period of the repeating signalling cycle, and to not exchange the predetermined signalling with the first network node during a portion of the repeating signalling cycle other than the first wake period; and each terminal device in the second group of terminal devices is operable to exchange predetermined signalling with the second network node during the second wake period of the repeating signalling cycle, and to not exchange the predetermined signalling with the second network node during a portion of the repeating signalling cycle other than the second wake period. |
