Embodiment Construction

[0034] The principle and spirit of the present disclosure will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that these specific embodiments are described only to enable those skilled in the art to better understand and realize the present disclosure, rather than to limit the scope of the present disclosure in any way.

[0035]As mentioned above, one of the purposes of the embodiments of the present disclosure is to perform D2D discovery transmission on a non-primary cell belonging to a scenario within a public land mobile network (PLMN) or in an inter-PLMN scenario while performing cellular transmission on a primary cell. In order to achieve this goal, two problems need to be solved. The problem in the first aspect is how to obtain the discovery transmission resource in the non-primary cell, and the problem in the second aspect is how to allocate power when the user equipment needs to perform cel...

Abstract

An embodiment of the present disclosure provides a method for a user equipment that performs cellular transmission via a serving base station, the method may include: sending a request message to the serving base station to request allocation of a device-to-device D2D discovery transmission resources; receiving an indication message for indicating the allocated resources from the serving base station; and performing D2D discovery transmission and cellular transmission on the allocated resources simultaneously. Embodiments of the present disclosure also provide a method for a serving base station, a user equipment, and a serving base station.

Description

technical field [0001] Embodiments of the present disclosure relate generally to wireless communications, and more particularly to a user equipment and serving base station and methods therefor. Background technique [0002] In LTE Release 12, ProSe (ProSe) Direct Discovery has been introduced in LTE-A, ProSe is also known as Device-to-Device D2D communication service, where user equipment can transmit in the primary cell (i.e. PCell) D2D discovery signal. In LTE Release 13, ProSe Direct Discovery needs to be enhanced to support discovery transmissions in non-serving cells and / or secondary cells, which may belong to the same PLMN as the serving cell or a different PLMN. [0003] According to the agreement reached in the RAN2#89bis meeting, it may be allowed to configure the user equipment to transmit the D2D discovery signal in another carrier via RRC signaling. RRC signaling can be used to configure Type 1 or Type 2 discovery configurations for non-primary cells. However...
