Abstract
An embodiment of a system that operates a user equipment as a serving user equipment in a personal cell. The user equipment is configured to receive a communication resource from a base station to operate as a serving user equipment in a personal cell, the communication resource including a personal cell ID, and transmit in a cellular downlink the personal cell ID and control channel information included in the communication resource to a second user equipment. The communication resource can comprise a downlink of a cellular network for data transmission by the user equipment to the second user equipment. The user equipment retains a cellular communication link to a base station.
Claims22
A user equipment, comprising:
- a transceiver;
- and
- a processor coupled to the transceiver, the processor, in conjunction with the transceiver, configured to:
- receive an allocation of a communication resource from a base station to function as a serving user equipment (“UE”) in a personal cell (“PC”), the communication resource including a PC identifier (“ID”) that identifies the personal cell, and
- transmit in a cellular downlink the PC ID and control channel information included in the communication resource.
A base station, comprising:
- a transceiver;
- and
- a processor coupled to the transceiver, the processor, in conjunction with the transceiver, configured to cause the base station to transmit a communication resource to a first UE for the first UE to operate as a serving UE in a PC, the communication resource including a PC ID and another communication resource for another UE to respond to the PC ID in an uplink to establish a D2D communication link with the first UE.
A method comprising:
- receiving by a user equipment a communication resource from a base station to operate the user equipment as a serving UE in a PC, the communication resource including a PC ID;
- and
- transmitting in a cellular downlink the personal cell ID and control channel information contained in the communication resource.
A method for base station operations, the method comprising transmitting a communication resource to a first UE for the first UE to function as a serving UE in a PC, the communication resource including a PC ID and a communication resource for another UE to respond to the PC ID in an uplink to establish a D2D communication link with the first UE.
