Abstract
Embodiments provide a user equipment handover method, and a device. In embodiments of the present invention, when a handover is to be performed, user equipment may send first information that is used to request a handover, and then a destination network device may allocate a first uplink resource to the user equipment.
Claims23
An apparatus, comprising:
- at least one processor;
- and
- a non-transitory memory storing instructions executable by the at least one processor, wherein the instructions instruct the at least one processor to perform operations comprising:
- send a measurement report to a control network device;
- receive a handover command from the control network device, wherein the handover command notifies the apparatus of a symbol location of a synchronization signal of a destination network device, wherein the synchronization signal is usable to complete downlink synchronization with the destination network device;
- and
- receive, according to the received symbol location, the synchronization signal from the destination network device.
4 more elements
An apparatus, comprising:
- at least one processor;
- and
- a non-transitory memory storing instructions executable by the at least one processor, wherein the instructions instruct the at least one processor to perform operations comprising:
- receive a measurement report from user equipment (UE);
- and
- send a handover command to the UE, wherein the handover command notifies the UE of a symbol location of a synchronization signal of a destination network device, and wherein the synchronization signal is usable to complete downlink synchronization with the destination network device.
3 more elements
An apparatus, comprising:
- at least one processor;
- and
- a non-transitory memory storing instructions executable by the at least one processor, wherein the instructions instruct the at least one processor to perform operations comprising:
- receive a handover request from a control network device, wherein the handover request indicates that user equipment (UE) requests to be handed over to the apparatus;
- and
- send a handover response to the control network device, wherein the handover response notifies the control network device of a symbol location of a synchronization signal of the apparatus, and wherein the synchronization signal is usable to complete downlink synchronization with the apparatus.
3 more elements
A communication system, comprising:
- a control network device;
- and
- a destination network device;
- wherein the control network device comprises:
- a first non-transitory memory storage comprising first instructions;
- and
- a first hardware processor in communication with the first non-transitory memory storage, wherein the first hardware processor executes the first instructions to:
- receive a measurement report from user equipment (UE);
- and
- send a handover request to the destination network device, wherein the handover request indicates that the UE requests to be handed over to the destination network device;
- wherein the destination network device comprises:
- a second non-transitory memory storage comprising second instructions;
- and
- second hardware processor in communication with the second non-transitory memory storage, wherein the second hardware processor executes the second instructions to:
- send a handover response to the control network device, wherein the handover response notifies the control network device of a symbol location of a synchronization signal of the destination network device, and wherein the synchronization signal is usable to complete downlink synchronization with the destination network device;
- and
- wherein the first hardware processor further executes the first instructions to:
- receive the handover response from the destination network device;
- and
- send a handover command to the UE based on the handover response, wherein the handover command notifies the UE of the symbol location of the synchronization signal of the destination network device.
