Abstract
Methods, apparatuses and systems are described. A device, in the active state, receives, from a serving transmission point, a device connection identifier (DCID) associated with the device. The device, in the standby state, periodically transmits, to the same or different serving transmission point, an identifying signal that identifies the first device using the DCID, to synchronize the first device with a wireless communications network.
Claims19
A method performed by a first device, the method comprising:
- in an active state:
- performing an initial access procedure to associate the first device with a serving transmission point in a wireless communications network;
- receiving, from the serving transmission point during the initial access procedure, a device connection identifier (DCID) associated with the first device, the DCID containing multiple fields, the multiple fields of the DCID including a type field for identifying a device type of the first device, the type field providing information useable by the wireless communications network to determine network resources to be used for sending data to the first device;
- and
- transitioning from the active state to a standby state different from the active state;
- in the standby state different from the active state, the DCID being maintained in the standby state, the standby state supporting a reduced set of device functionality and being supported by reduced network resources compared to the active state:
- periodically transmitting, to the same or different serving transmission point, an identifying signal that identifies the first device using the DCID, to synchronize the first device with the wireless communications network;
- after synchronization, receiving or transmitting data from the same or different serving transmission point, while remaining in the standby state;
- and
- transitioning from the standby state to the active state, and maintaining the DCID from the standby state to the active state.

An apparatus comprising:
- a communications interface for communicating with a wireless communications network;
- and
- a processor coupled to the communications interface, the processor being configured to execute computer-readable instructions that, when executed by the processor, cause the apparatus to:
- in an active state:
- perform an initial access procedure to associate the apparatus with a serving transmission point in the wireless communications network;
- receive, from the serving transmission point during the initial access procedure, a device connection identifier (DCID) associated with the apparatus, the DCID containing multiple fields, the multiple fields of the DCID including a type field for identifying a device type of the apparatus, the type field providing information useable by the wireless communications network to determine network resources to be used for sending data to the apparatus;
- and
- transition from the active state to a standby state different from the active state;
- in the standby state different from the active state, the DCID being maintained in the standby state, the standby state supporting a reduced set of device functionality and being supported by reduced network resources compared to the active state:
- periodically transmit, to the same or different serving transmission point, an identifying signal that identifies the apparatus using the DCID, to synchronize the apparatus with the wireless communications network;
- after synchronization, receive or transmit data from the same or different serving transmission point, while remaining in the standby state;
- and
- transition from the standby state to the active state, and maintain the DCID from the standby state to the active state.

A system, comprising a wireless device and a first serving transmission point;
- wherein the wireless device is configured to:
- in an active state:
- perform an initial access procedure to associate the wireless device with the first serving transmission point in a wireless communications network;
- receive, from the first serving transmission point during the initial access procedure, a device connection identifier (DCID) associated with the wireless device, the DCID containing multiple fields, the multiple fields of the DCID including a type field for identifying a device type of the wireless device, the type field providing information useable by the wireless communications network to determine network resources to be used for sending data to the wireless device;
- and
- transition from the active state to a standby state different from the active state;
- in the standby state different from the active state, the DCID being maintained in the standby state, the standby state supporting a reduced set of device functionality and being supported by reduced network resources compared to the active state:
- periodically transmit, to the first serving transmission point, an identifying signal that identifies the wireless device using the DCID;
- and
- wherein the first serving transmission point is configured to:
- receive, from the wireless device that is in the standby state, the identifying signal;
- and
- provide synchronization information to the wireless device;
- wherein the wireless device is further configured to:
- receive the synchronization information;
- synchronize with the wireless communications network using the synchronization information;
- after synchronization, receive or transmit data from the first serving transmission point, while remaining in the standby state;
- and
- transition from the standby state to the active state, and maintain the DCID from the standby state to the active state.
