Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0049] In order to solve the problem that in the prior art communication system, when the carriers overlap, the carriers interfere with each other, resulting in failure to work normally, the embodiment of the present invention is based on Figure 1A , Figure 1B or Figure 1C The communication system shown as an example proposes a solution to eliminate interference between carriers while improving resource utilization in the communication system.

[0050] Such as Figure 1A , Figure 1B and Figure 1C As shown, the embodiment of the present invention provides a communication system 100 . The communication system 100 includes at least one base station (base station, BS) and multiple UEs. For example, in Figure 1A , Figure 1B and Figure 1C In , multiple UEs can be respe...

Abstract

The invention relates to the technical field of wireless communications and provides a carrier transmission method, a base station, user equipment and a communication system. The method discloses a base station to send a second carrier, wherein at least part of the second carrier shares the same resource area with a first carrier, and the resource area comprises a plurality of resource units; thefirst carrier and the second carrier occupy different resource units; the base station sends blank resource unit indication information to the user equipment receiving the second carrier, wherein theblank resource unit indication information is used for indicating the position of a resource unit occupied by the first carrier in the shared resource region. According to the scheme provided by the embodiment, the resource utilization rate of the communication system is improved, and interference between carriers is avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a carrier transmission method, base station, user equipment and system. Background technique [0002] In a wireless communication system, usually each carrier is deployed in a frequency division multiplex (frequency division multiplex, FDM) manner, and a guard interval is reserved between two carriers. For example, carrier one occupies a fixed 10M bandwidth, carrier two occupies a fixed 20M bandwidth, and carrier one and carrier two reserve a certain guard interval bandwidth. [0003] The traditional carrier width is generally fixed, for example, it is fixed at 5M in Universal Mobile Telecommunications System (UMTS), and it is fixed at 1.4M, 3M, 5M, 15M, 20M, etc. in Long Term Evolution (LTE). Using a fixed carrier bandwidth will easily cause a waste of spectrum resources when the spectrum is irregular. Therefore, in order to solve this problem, the exist...
