| 20080212551 | WIRELESS DATA TRANSMISSION METHOD, TRANSMITTING SYSTEM, AND RECEIVING SYSTEM - A wireless data transmission method is disclosed, in which a transmitter buffers current RLC layer data. The method includes the following steps: the transmitter transmits the current RLC layer data to a receiver; receives a data-receiving packet indicating that the data is incorrectly received, the physical layer of the receiver generated and fed back by the physical layer of the receiver if a physical layer of the receiver determines that the data is incorrectly received; and transmits the buffered current RLC layer data to the receiver. A transmitting system and a receiving system are further disclosed. The method of the present disclosure may enhance the data transmission speed over the RLC layer. | 09-04-2008 |
| 20090010366 | METHOD AND DEVICE FOR SUPPRESSING NARROWBAND INTERFERENCE - The method obtains an interference detection result by detecting sampled digital signals in real time in a transform domain, then maps the interference detection result into an interference suppression pulse function on the basis of a unit noise pulse function, and carries out interference suppression filtering in the transform domain according to the interference suppression pulse function. The present invention is capable of detecting narrowband interference such as monotone, frequency modulation, and phase modulation interferences in a receive channel adaptively in real-time, and suppressing the interference adaptively according to the quantity, energy and bandwidth of the interference, so as to reduce the influence of the interference. Therefore, the present invention may enhance robustness of the communication system against interference. Moreover, the present invention does not need multiple notch devices, costs low and may be implemented simply and reliably. | 01-08-2009 |
| 20110013577 | METHOD AND NETWORK DEVICE FOR CONTROLLING USER EQUIPMENT ACCESS IN MULTI-FREQUENCY SYSTEM - A method for controlling user equipment (UE) access in a multi-frequency system in the field of communication is provided. The method includes the following steps. A network side receives an access preamble sent by a UE on one frequency. When the network side determines that the UE needs to access on another frequency, the network side notifies the UE to access by switching to another frequency. Network device is also provided at the same time. Therefore, the UE access can be controlled according to a practical situation of the UE or each frequency, and the flexibility of the multi-frequency system is enhanced. | 01-20-2011 |
| 20110026422 | METHOD AND APPARATUS FOR CONTROLLING CARRIER FREQUENCY IN MULTI-CARRIER/CELL SYSTEM - A method and an apparatus for controlling a carrier frequency in a multi-carrier/cell system are provided. The method includes receiving Channel Quality Indicator (CQI) information of a carrier frequency reported by a terminal, determining whether to deactivate or activate the carrier frequency according to the CQI information, and instructing the terminal to deactivate or activate the carrier frequency according to a result of the determining. Thus, a certain carrier frequency is flexibly activated or deactivated in the multi-carrier/cell system through carrier frequency quality reporting and threshold comparison. | 02-03-2011 |
| 20110149781 | RESOURCE MANAGEMENT METHOD, APPARATUS AND SYSTEM IN A MULTI-CARRIER SYSTEM - The present invention relates to the field of communications technologies. A resource management method, apparatus, and system in a multi-carrier system are disclosed. The multi-carrier system includes at least one multi-carrier cell and the multi-carrier cell includes at least two single carrier establishing cooperation. The method includes the following steps: A base station measures the cooperative resource usage information of each cooperation established single carrier cell; the base station reports the cooperative resource usage information to a radio network controller for the radio network controller to perform resource management. The information measured and reported by the base station in the embodiment of the present invention can satisfy the needs of the multi-carrier performing resource management and make sure that the radio network controller can perform reasonable admission control over multi-carrier UEs. | 06-23-2011 |
