Abstract
A wake-up signal being for providing an indication to one or more of the communications devices (UEs) that they should receive a paging message in one or more of a plurality of paging occasions, and transmitting a candidate indicator message to the one or more UEs in an unused portion of radio resources of the wireless access interface that is allocated for signals other than the candidate indicator message, the candidate indicator message indicating one or more characteristics of the wake-up signal by which the wake-up signal may be transmitted as one or more candidates, wherein the one or more candidates are to be searched for detection of the wake-up signal by the one or more UEs.
Claims18
A method of operating an infrastructure equipment in a wireless communications system comprising the infrastructure equipment forming part of a wireless communications network and a plurality of communications devices, wherein the method comprises:
- providing a wireless access interface for communication between the infrastructure equipment and the communications devices,
- allocating a portion of radio resources of the wireless access interface as a search space for the communications devices to search for a wake-up signal transmitted by the infrastructure equipment, the wake-up signal being for providing an indication to one or more of the communications devices that they should receive a paging message in one or more of a plurality of temporally spaced paging occasions, and
- initiating a two-level wake-up signaling (WUS) operation, including, as part of a first level of the two-level WUS operation, transmitting, prior to the wake-up signal, a candidate indicator message to the one or more communications devices in an unused portion of radio resources of the wireless access interface that is allocated for signals other than the candidate indicator message,
- wherein the candidate indicator message indicates one or more characteristics of the wake-up signal associated with transmission of the wake-up signal as one or more candidates, and
- wherein the one or more candidates are to be searched for detection of the wake-up signal by the one or more communication devices.
Circuitry for an infrastructure equipment forming part of a wireless communications system comprising the infrastructure equipment and a plurality of communications devices, wherein the infrastructure equipment comprises transceiver circuity and controller circuitry which are configured in combination
- to provide a wireless access interface for communication between the infrastructure equipment and the communications devices,
- to allocate a portion of radio resources of the wireless access interface as a search space for the communications devices to search for a wake-up signal transmitted by the infrastructure equipment, the wake-up signal being for providing an indication to one or more of the communications devices that they should receive a paging message in one or more of a plurality of temporally spaced paging occasions, and
- to initiate a two-level wake-up signaling (WUS) operation, including, as part of a first level of the two-level WUS operation, to transmit, prior to the wake-up signal, a candidate indicator message to the one or more communications devices in an unused portion of radio resources of the wireless access interface that is allocated for signals other than the candidate indicator message,
- wherein the candidate indicator message indicates one or more characteristics of the wake-up signal associated with transmission of the wake-up signal as one or more candidates, and
- wherein the one or more candidates are to be searched for detection of the wake-up signal by the one or more communication devices.
Circuitry for a communications device forming part of a wireless communications system comprising an infrastructure equipment and the communications device, wherein the communications device comprises transceiver circuitry and controller circuitry which are configured in combination
- to receive, based on a two-level wake-up signaling (WUS) operation, as part of a first level of the two-level WUS operation, a candidate indicator message from the infrastructure equipment in an unused portion of radio resources of the wireless access interface that is allocated for signals other than the candidate indicator message, and
- to search, after receiving the candidate indicator message, in a portion of radio resources defining a search space, for a wake-up signal transmitted by the infrastructure equipment,
- wherein the wake-up signal is for providing an indication to the communications device that the communication device should receive a paging message in one or more of a plurality of temporally spaced paging occasions,
- wherein the candidate indicator message indicates one or more characteristics of the wake-up signal associated with transmission of the wake-up signal as one or more candidates, and
- wherein the one or more candidates are to be searched for detection of the wake-up signal by the one or more communication devices.
