In the embodiments of the present invention, sub-frame configuration of a backhaul link can be performed in the switching process, configuration of a carrier aggregation cell is coordinated, influence on operation of the RN is reduced, service continuity of a user is ensured maximally, and the number of discarded packets is reduced, thereby providing good network experiences for the user. | 2013-11-21 |
20130308523 | METHOD FOR CONFIGURING A BACKHAUL LINK SUBFRAME IN A WIRELESS COMMUNICATION SYSTEM TO WHICH A CARRIER AGGREGATION SCHEME IS APPLIED AND AN APPARATUS FOR THE SAME - A method for configuring a backhaul link subframe in a wireless communication system to which a carrier aggregation scheme is applied and an apparatus for the same are disclosed. The method comprises determining one of a plurality of subframe configurations as a first subframe configuration for a primary component carrier allocated to the relay node; configuring subframe configuration candidates for one or more secondary component carriers allocated to the relay node on the basis of the determined first subframe configuration; determining a second subframe configuration for each of the one or more secondary component carriers by using the configured subframe configuration candidates; and transmitting and receiving a signal to and from the relay node in accordance with the first subframe configuration and the second subframe configuration. | 2013-11-21 |
20130308524 | DISTRIBUTED INTERFERENCE MANAGEMENT ALGORITHM - A method, a computer program product, and an apparatus are provided. In a first configuration, an AP receives a transmission request from a UE in a communication link with the AP. The AP determines whether to yield a transmission request response to the transmission request based on one or more transmission requests received from at least one communication link with at least one other AP, but not from UEs in communication links with the AP. In a second configuration, an AP receives a transmission request response from a UE in a communication link with the AP. The AP determines whether to yield a data transmission to the UE based on one or more transmission requests responses received from at least one communication link with at least one other AP, but not from UEs in communication links with the AP. | 2013-11-21 |
