Problems solved by technology

[0011] In this case, even if each side of the connection obeys the UE's processing capability, neither the macro base station nor the small base station can ensure that the total resource allocation of the two connections can respect the UE's processing capability

Embodiment Construction

[0067] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0068] refer to figure 1 , the communication system according to the present invention includes a macro base station, at least one small base station corresponding to the macro base station, and at least one user equipment, wherein the user equipment can be connected to a macro base station and a small base station at the same time, that is, the user There is dual connectivity between the device and a macro base station and a small base station.

[0069] Wherein, the small base station according to the present invention includes, but is not limited to, a base station implemented by technologies such as femtocell (Femtocell), picocell (Picocell), and microcell (Microcell).

[0070] refer to figure 2 . figure 2 A flowchart of a method for transmitting data with a UE through dual connectivity according to an embodiment of the present invention is shown. ac...

Abstract

An objective of the present invention lies in providing a method, apparatus, and system for performing data transmission and processing via dual connectivity. A method according to the present invention comprises: obtaining capability related information of the UE; obtaining allocation related information; determining available allocation information corresponding to said macro base station itself and capability allocation information corresponding to said small base station based on the capability related information of said UE and said allocation related information; configuring connection between said macro base station and said UE based on said available allocation information, so as to perform data transmission between said macro base station and said UE and transmit said capability allocation information to said small base station. An advantage of the present invention lies in that by setting processing capability thresholds of a UE which is available respectively for the macro base station and the small base station based on capability related information of the UE, the data transmission on dual connectivity of the UE to the macro base station and the small base station will not exceed the processing capability of the UE.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, device and system for data transmission and processing through dual connections. Background technique [0002] In the prior art, when configuring and scheduling user equipment (UE, User Equipment), the evolved UMTS terrestrial radio access network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) needs to comply with UE radio access capability parameters (Radio Access parameters). [0003] UE wireless access parameters include UE type and parameter information independent of UE type, including Packet Data Convergence Protocol (PDCP, Packet Data Convergence Protocol) parameters supported by UE, radio link control (RLC, Radio Link Control) parameters, physical layer parameters supported by the UE, radio frequency (RF, Radio Frequency) parameters supported by the UE, and so on. When the UE accesses the network for the first time, the network...
