Method and device for enabling multi-carriers aggregation transmission
First Claim
1. A transmission method with Time Division Duplex (TDD) multi-carrier aggregation, comprising:
- performing uplink and downlink configurations for each of a plurality of component carriers aggregated in a cell while ensuring coexistence of at least one identical uplink sub-frame and at least one identical downlink sub-frame between at least two of the component carriers and compliance of the configuration of at least one of the component carriers with an uplink and downlink configuration of R8; and
transmitting the uplink and downlink configuration of any one of the component carriers and those of other component carriers aggregated with the any one of the component carriers to an LTE-A UE accessing a corresponding component carrier, wherein the LTE-A UE is scheduled over sub-frames that are all in the uplink or downlink in a plurality of aggregated component carriers when the LTE-A UE is to receive or transmit data simultaneously over a plurality of carriers.

Abstract
The present invention discloses a transmission method with multi-carrier aggregation, which includes: performing uplink and downlink configurations for each of the component carriers aggregated in a cell and ensuring coexistence of at least one identical uplink sub-frame and at least one identical downlink sub-frame between at least two of the component carriers and compliance of the configuration of at least one of the component carriers with an uplink and downlink configuration of R8; and transmitting the uplink and downlink configuration of any one of the component carriers and those of the other component carriers aggregated with the any one component carrier to an LTE-A UE accessing the corresponding component carrier. The invention further provides a transmission device with multi-carrier aggregation. With the invention, uplink and downlink configurations in an LTE-A system can be performed to accommodate a demand of a TDD system.

13. A transmission method with Time Division Duplex (TDD) multi-carrier aggregation, comprising:
-
receiving, by an LTE-A UE, over an access carrier thereof, an uplink and downlink configuration of the access carrier and those of other component carriers aggregated with the access carrier transmitted from a base station; and receiving, by an LTE UE, over the access carrier thereof by the LTE UE, an uplink and downlink configuration of the access carrier transmitted from the base station, wherein physical or logic resources are preset over each component carrier to carry information on the uplink and downlink configuration of a current carrier and those of other carriers aggregated with the current carrier; extracting, by the LTE-A UE, the uplink and downlink configuration of the access carrier over the physical or logic resource preset over the access carrier to carry the information on the uplink and downlink configuration of the access carrier and extracting the uplink and downlink configurations of the other carriers aggregated with the access carrier over the physical or logic resource preset over the access carrier to carry the information on the uplink and downlink configuration of the other carriers aggregated with the access carrier, wherein the LTE-A UE is scheduled over sub-frames that are all in the uplink or downlink in a plurality of aggregated carriers when the LTE-A UE is to receive or transmit data simultaneously over a plurality of carriers; and extracting, by the LTE UE, the uplink and downlink configuration of the access carrier over the physical or logic resource preset over the access carrier to carry the information on the uplink and downlink configuration of the access carrier.
