Embodiment Construction

[0135] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0136] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood that the ...

Abstract

Provided in the present disclosure are a cross-carrier scheduling method and device, wherein the method comprises: sending scheduling information to a terminal, the scheduling information being used for cross-carrier scheduling a target bandwidth portion on at least one target carrier by means of a scheduling carrier, wherein the target carrier is a carrier that is scheduled by the scheduling carrier and that is configured with at least one bandwidth portion, the bandwidth portion is a frequency domain resource pre-designated on a carrier, and the target bandwidth portion is a bandwidth portion that is scheduled by the scheduling carrier among all bandwidth portions on the target carrier. According to the present disclosure, a target bandwidth portion on at least one target carrier may bescheduled by a scheduling carrier, and the target carrier configured with the at least one bandwidth portion may be scheduled across bandwidth portions at the same time that cross-carrier scheduling is implemented, thereby achieving a more flexible scheduling mode. In addition, at the same time that cross-bandwidth portion scheduling is implemented, resources of different bandwidth portions on a carrier may be fully utilized, thereby reducing the blocking probability of a control signaling.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a cross-carrier scheduling method and device. Background technique [0002] In the related art, in order to avoid the interference problem on the control channel in the heterogeneous network and to realize the load balancing of the control areas on different carriers, cross-carrier scheduling can be performed. At least one other carrier is scheduled through the scheduling carrier carrying the scheduling information. [0003] In a new generation communication system, a terminal may support at least one bandwidth part on one carrier, and the terminal may have different numerology (parameter sets) on different carriers or bandwidth parts. However, in the related art, there is no solution on how to schedule bandwidth parts across carriers. Contents of the invention [0004] In order to overcome the problems existing in related technologies, the embodiments o...
