Random access method, network node and user equipment
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides a random access method, a network node and a user equipment. With the solution of the above embodiment of the present disclosure, the performance of the UE randomly accessing the target cell can be improved.
1. A method by a user equipment (UE) in a wireless communication system, the method comprising:
measuring a signal of a target cell;
transmitting, to a network node, a measurement report on the signal of the target cell;
receiving, from the network node, a handover command including resource configuration information comprising random access resource configuration information indicating that a random access is to be performed on a supplementary uplink; and
performing the random access to the target cell based on the resource configuration information.
2. The method according to claim 1 , wherein the resource configuration information includes an indication indicating to the UE whether to use a normal uplink or the supplementary uplink for the random access.
3. A method by a network node in a wireless communication system, the method comprising:
receiving, from a user equipment (UE), a measurement report on a signal of a target cell; and
transmitting, to the UE, a handover command including resource configuration information comprising random access resource configuration information indicating that a random access is to be performed on a supplementary uplink based on the measurement report.
4. The method according to claim 3 , wherein the resource configuration information includes an indication indicating to the UE whether to use a normal uplink or the supplementary uplink for the random access.
5. A user equipment, comprising:
a communication interface configured to communicate;
a processor; and
a memory storing computer-executable instructions that, when executed by the processor, cause the processor to perform the following operations:
measuring a signal of a target cell;
transmitting, to a network node, a measurement report on the signal of the target cell;
receiving, from the network node, a handover command including resource configuration information comprising random access resource configuration information indicating that a random access is to be performed on a supplementary uplink; and
performing the random access to the target cell based on the resource configuration information.
6. The user equipment according to claim 5 , wherein the resource configuration information includes an indication indicating to the UE whether to use a normal uplink or the supplementary uplink for the random access.
7. A network node, comprising:
a communication interface configured to communicate;
a processor; and
a memory storing computer-executable instructions that, when executed by the processor, cause the processor to perform the following operations:
receiving, from a user equipment (UE), a measurement report on a signal of a target cell; and
transmitting, to the UE, a handover command including resource configuration information comprising random access resource configuration information indicating that a random access is to be performed on a supplementary uplink based on the measurement report.
8. The network node according to claim 7 , wherein the resource configuration information includes an indication indicating to the UE whether to use a normal uplink or the supplementary uplink for the random access.
