Embodiment Construction

[0050] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0051] Figure 1a It is a flowchart illustrating a method for flexibly disabling / enabling cross-carrier scheduling in carrier aggregation wireless data transmission according to an embodiment of the present invention.

[0052] In step 101, the radio network node 300 allocates component carriers to the mobile node 200a for radio data transmission in carrier aggregation. In step 102, the radio network node 300 allocates a time division duplex uplink / downlink configuration for the allocated component carriers. Then at step 103, the allocated TDD UL / DL configuration is sent to the mobile node 200a.

[0053] Then in step 104, the radio network node 300 configures cross-carrier scheduling for the mobile node 200a. In step 105, the configured cross-carrier scheduling configuration is sent to the mobile node 200a.

[0054] In step 106 the r...

Abstract

The invention allows flexible disabling / enabling of cross-carrier scheduling in carrier-aggregated wireless data transmission. In response to detecting a predetermined disabling indication of cross-carrier scheduling of received carrier aggregated wireless data transmission, the disabling indication targeting subframes allocated to uplink in a first component carrier transmitted from a cross-carrier scheduling cell and to downlink in a second component carrier transmitted from a cross-carrier scheduled cell: a downlink control region in the targeted subframes in the second component carrier is monitored for uplink / downlink grants; and in response to detecting an uplink / downlink grant, the detected uplink / downlink grant is utilized in uplink / downlink scheduling of the targeted subframe in the second component carrier.

Description

technical field [0001] The present invention relates generally to mobile communications. In particular, the present invention relates to a method, an apparatus and a radio network node for flexibly disabling / enabling cross-carrier scheduling in wireless data transmission in carrier aggregation. Background technique [0002] Long Term Evolution (LTE) was introduced in Release 8 of the 3rd Generation Partnership Project (3GPP), which is a technical specification for a 3rd generation mobile communication system. LTE is a technology for mobile data transmission that aims, among other things, to increase data transfer rates and reduce latency. LTE uses Orthogonal Frequency Division Multiple Access (OFDMA) as its multiple access method in the downlink. The uplink uses Single Carrier Frequency Division Multiple Access (SD-FDMA). 3GPP Release 10 introduced the next version of LTE, called LTE-Advanced (LTE-A), to address the 4th generation system requirements. [0003] Both LTE a...
