Abstract
There is provided a wireless terminal device and a network node in a communications network. The wireless terminal device is operable in a plurality of modes including a first mode, in which the wireless terminal device is able to receive paging messages from the wireless communications network, and a second mode in which the wireless terminal device is unable to receive paging messages from the wireless communications network. The method in the wireless device includes receiving a signal from a network node operable in the wireless communications network, wherein the signal includes information related to the paging occasions; and responsive to a determination to that signal, operating in at least the second mode.
Claims8
A method performed by a wireless terminal, the method comprising:
- awakening from a sleep mode and detecting a Wake-up Signal (WUS) indicating a plurality of paging occasions (POs) in a paging time window transmitted by a network node of a wireless communications network;
- determining whether to perform further WUS detection within the paging time window based on whether the wireless terminal awakened in a same cell with respect to last entering the sleep mode;
- and
- monitoring the plurality of POs indicated by the WUS without performing further WUS detection within the paging time window, in response to detecting the WUS and determining that the wireless terminal awakened in the same cell.
A wireless terminal comprising:
- transceiver circuitry;
- and
- processing circuitry configured to use the transceiver circuitry to:
- awaken from a sleep mode and detect a Wake-up Signal (WUS) indicating a plurality of paging occasions (POs) in a paging time window transmitted by a network node of a wireless communications network;
- determine whether to perform further WUS detection within the paging time window based on whether the wireless terminal awakened in a same cell with respect to last entering the sleep mode;
- and
- monitor the plurality of POs indicated by the WUS without performing further WUS detection within the paging time window, in response to detecting the WUS and determining that the wireless terminal awakened in the same cell.
