Document Type and Number:
WIPO Patent Application WO/2023/287346
Kind Code:
A3
Abstract:
A wireless communication device (12) is configured for use in a wireless communication network (10). The wireless communication device (10) switches from a first state (S1), in which wireless communication equipment (16) of the wireless communication device (12) keeps track of time, to a second state (S2) in which the wireless communication equipment (16) does not keep track of time. Before or as part of switching from the first state (S1) to the second state (S2), the wireless communication device (12) obtains a time reference (22). While in the second state (S2), the wireless communication device (12) stores the time reference (22) in memory (24). After or as part of switching from the second state (S2) to the first state (S1), the wireless communication device (12) resumes track of time using the time reference (22). (Figure 1A)
