20130265992 | METHOD, APPARATUS AND SYSTEM FOR SYNCHRONIZATION BETWEEN BASE STATIONS - The present invention provides a method, an apparatus, and a system for synchronization between base stations. The method for synchronization between base stations includes: A first base station receives synchronization information sent by a user equipment, where the first base station is a serving base station of the user equipment; and the first base station adjusts a downlink sending time point and an uplink receiving time point of the first base station according to the synchronization information, so as to keep consistency between the downlink sending time point of the first base station and a downlink sending time point of a second base station that serves as a synchronization time reference and keep consistency between the uplink receiving time point of the first base station and an uplink receiving time point of the second base station. | 10-10-2013 |
20140098746 | COMMUNICATION METHOD, BASE STATION, AND TERMINAL DEVICE - The present invention provides a communication method. The method includes: determining, by a first base station serving a first cell, a position of an almost blank subframe and transmission power of the almost blank subframe according to obtained adjustment information about a second cell of a second base station; and determining a frame structure for the second cell according to the adjustment information, the position of the almost blank subframe, and the transmission power of the almost blank subframe. The present invention further provides a base station and a terminal device. With the present invention, transmission power of each almost blank subframe may be adaptively adjusted according to the adjustment information about the second cell, so that interference between the first cell and the second cell is reduced. | 04-10-2014 |

20150289260 | Wireless Communication Method, Access Device, and Wireless Communications System - The present invention relates to a wireless communication method, an access device, and a wireless communications system. The method includes: acquiring, by a first access device, uplink information of a second access device, where the first access device and the second access device are inter-frequency devices or inter-system devices; and receiving, by the first access device, an uplink signal of the second access device according to the uplink information, where the uplink information includes frequency information of an uplink of the second access device. According to the present invention, an objective that the first access device receives a signal sent by user equipment of the inter-system or inter-frequency second access device, and that the first access device identifies whether the user equipment falls within a coverage area of the first access device or is near to the first access device is achieved, thereby enhancing cooperation between different access devices. | 10-08-2015 |
20150296447 | WIRELESS LOCAL AREA NETWORK ACCESS POINT SEARCH METHOD, APPARATUS, AND SYSTEM - The present application discloses a wireless local area network access point search method, an apparatus, and a system, relates to the field of communications technologies, and can reduce power consumption for passive scanning. According to the method, beacon sending information of a wireless local area network access point and measurement information of a user equipment are matched, so that the user equipment can search for the wireless local area network access point only at the time when and a frequency channel number at which the wireless local area network access point sends a beacon. Compared with the prior art in which a user equipment needs to continuously keep a state of searching for a wireless local area network access point, the present application greatly shortens time spent by the user equipment in listening to a beacon, and therefore reduces power consumption of passive scanning. | 10-15-2015 |
