US 2018/0027429 A1 · DATA TRANSMISSION METHOD, USER EQUIPMENT, AND BASE STATION

Abstract

Embodiments of the present disclosure provide a data transmission method, including: receiving, by a first user equipment (UE), a first message sent by a second UE, where the first message includes indication information that the second UE is capable of acting as a relay UE; and performing, by the first UE, data transmission with a base station via the second UE, where the second UE acts as a relay UE. In embodiments of the present disclosure, when first UE is unable to directly perform data transmission with a base station, the first UE uses second UE as a relay UE according to indication information sent by the second UE that the second UE is capable of acting as a relay UE, and then is unable to perform data transmission via the relay UE. Therefore, a success rate of data transmission can be ensured, and further transmission efficiency can be increased.

Dependent claims

A data transmission method, comprising:

receiving, by a first user equipment (UE), a first message sent by a second UE, wherein the first message comprises indication information that the second UE is capable of acting as a relay UE;
and
performing, by the first UE, data transmission with a base station via the second UE, wherein the second UE acts as a relay UE.

A data transmission method, comprising:

receiving, by a second user equipment (UE), a relay request message sent by a first UE or by a base station, wherein the relay request message indicates that the first UE needs an assistance relay service;
determining, by the second UE according to the relay request message, that the second UE is capable of acting as a relay UE for the first UE;
and
acting, by the second UE, as a relay UE to assist the first UE to perform data transmission with the base station.

1 more element

A second user equipment (UE), comprising:

a receiver, configured for the second UE to receive a relay request message sent by a first UE or by a base station, wherein the relay request message indicates that the first UE needs an assistance relay service;
and
a processor, configured to:
determine, according to the relay request message, that the second UE is capable of acting as a relay UE for the first UE, and
use the second UE as a relay UE to assist the first UE to perform data transmission with the base station.
