Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of a wake up procedure for a hibernating cell. The method comprises determining whether configuration information for transmitting a wake up signal is received from a second device, the wake up signal used for waking up the second device in a hibernation mode; in accordance with a determination that the configuration information is missed, obtaining one or more reference parameters associated with the wake up signal; and transmitting the wake up signal to the second device based on the one or more reference parameters. In this way, a hibernating network could be waked up and provide service at any time when the UE requires the network service. The requirement for reducing power consumption of 5G site can be realized and meanwhile the service to be provided to the UE is not downgraded.

Abstract: Embodiments of the present disclosure relate to positioning target device. According to embodiments of the present disclosure, the location of the target device is measured by two anchor devices. The distances between the target device at a location and the anchor devices are measured and the distances between the target device at a further location and the anchor devices are also measured. The location of the target device is estimated based on the distances. In this way, fewer anchor devices are used to perform the positioning.

Abstract: An apparatus (10) comprising: means for determining a current state of each of a first alert module (20_1) and a second alert module (20_2) of a group (22) of alert modules (20), wherein a current state (S_1) of the first alert module (20_1) is dependent upon at least a current location (L_1) of the first alert module (20_1) and a current state (S_2) of the second alert module (20_2) is dependent upon at least a current location (L_2) of the second alert module (20_2); means (30) for providing a first warning signal (W_1) to a first entity (40_1) dependent at least partially on the current state (S_i) of the first alert module (20_1) and/or the second alert module (20_2) of the group (22) of alert modules (20); and means (30) for providing a second warning signal (W_2) to the first entity (40_1) and/or a second entity (40_2) dependent at least partially on the current state (S_i) of the first alert module (20_1) and/or the second alert module (20_2) of the group (22) of alert modules (20).
