Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 2, the present embodiment provides a kind of channel resource indicating means, comprises the following steps:
S21, acquisition strengthen the channel resource configured information of Physical Downlink Control Channel epdcch.
S22, to user equipment send described channel resource configured information.
Wherein, described channel resource configured information includes the resource instructions field of y bit;Described resource instructions field is used for indicating
The position of the resource that described epdcch is used;Y is positive integer.
The channel resource configured information of described enhancing Physical Downlink Control Channel epdcch is in Physical Downlink Control Channel
Pdcch carries, or is carried by high-level signaling;Described high-level signaling includes mac(medium access control, and media connect
Enter to control) ce(control element, control unit) signaling or rrc(radio resource control, Radio Resource
Control) signaling, or other signaling.
It should be noted that above-mentioned steps s21 ~ s22 can be executed by base station, described channel resource configured information is by base station
It is handed down to user equipment.Certainly, above-mentioned steps s21 ~ s22 can also be executed by the equipment with base station functions.Work as user equipment
After receiving described channel resource configured information, the money that epdcch uses can be determined according to described channel resource configured information
Source.
