Patent number: 7418010Abstract: A transmission method of multiple services combination is as follow. During service initialization of both communication sides, an identical TFCS (Transport Format Combination Set), containing all TFC (Transport Format Combination), is created in both sides. When a data is transmitted according to specific TFC at the transmitting end, a corresponding TFCI (Transport Format Combination Indicator) of the TFC is transmitted simultaneously. At the receiving end, the TFCI is used to look for the TFC in the TFCS. The TFCS is divided into no less than one sub-sets according to the specific channel characteristics of the service. TFCI is only used for looking for TFC in a sub-set, but not used to indicate the sub-set where the TFC is located. When data of services are transmitted with TFC at the transmitting end, the service specific channel characteristics are used to define a sub-set where the TFC is located at the receiving end, and the TFCI is used to look for the TFC in the sub-set.Type: GrantFiled: June 12, 2003Date of Patent: August 26, 2008Assignee: Huawei Technologies Co., Ltd.Inventors: Zhaohui Cai, Zexian Li

Publication number: 20040001529Abstract: The invention discloses a method for improving the channel estimation accuracy of a wireless communication system with uplink synchronization or downlink synchronization. The method uses a code block with a interference free window as pilot symbols, or a code block with a interference free window to make spread spectrum for the pilot symbols. The window width of the interference free window is greater than the maximum channel transmission impulse response length, and the codes number with a interference free window is greater than the maximum subscribers number of the system. With this method, during system inherent channel estimation the interference is reduced, so the channel estimation accuracy is improved. At the same time, multiple access interference of the system is suppressed and other noise affection is reduced, so the system performance is improved too. By configuring the system pilot symbols, the system can have more subscribers.Type: ApplicationFiled: April 18, 2003Publication date: January 1, 2004Applicant: Huawei Technologies Co., Ltd.Inventor: Zhaohui Cai
