Small cell, macro cell and transmission assist method for small cell

摘要

A small cell, a macro cell and a transmission assist method are provided. The small cell includes a transceiver and a processor. The processor generates a radio link failure (RLF) indication message when determining that an RLF count in a licensed band between the small cell and a user equipment reaches a threshold. The transceiver transmits the RLF indication message to the macro cell, and receives a modification request message from the macro cell. The modification message includes resource configuration information, and the resource configuration information indicates an unlicensed band radio resource of an unlicensed band. After confirming via the transceiver that the unlicensed band radio resource is available for data transmission with the user equipment, the processor generates a modification request acknowledge message, and transmits the modification request acknowledge message to the macro cell via the transceiver.

主权项

1. A small cell, comprising:
a transceiver; and a processor, being electrically connected to the transceiver, and configured to execute the following operations:
determining whether a radio link failure (RLF) count in a licensed band between the small cell and a user equipment reaches a threshold;generating an RLF indication message if the RLF count reaches the threshold, wherein the RLF indication message carries the RLF count;transmitting the RLF indication message to a macro cell via the transceiver;receiving a modification request message from the macro cell via the transceiver, wherein the modification request message includes resource configuration information, and the resource configuration information indicates an unlicensed band radio resource of an unlicensed band;confirming that the unlicensed band radio resource is available for subsequent data transmission with the user equipment via the transceiver; andafter confirming that the unlicensed band radio resource is available for the subsequent data transmission with the user equipment, generating a modification request acknowledge message and transmitting the modification request acknowledge message to the macro cell via the transceiver.
