Patent number: 11277845Abstract: The present disclosure relates to a network node and a method performed by the network node for radio resource allocation. The method includes allocating a number of subframes to a first terminal device for uplink transmission, in which the first terminal device repeatedly transmits its data to the network node for N times, wherein N is an integer greater than 1. Then the network node decodes the data received from the first terminal device after the data has been received for M times, wherein M is an integer smaller than N; and records, after the received data from the first terminal device is successfully decoded, rest of subframes being allocated to the first terminal device as recycling uplink resource. The recycling uplink resource can be reused by other communication links although been allocated to the first terminal device, thus radio resource can be utilized more efficiently.Type: GrantFiled: September 18, 2017Date of Patent: March 15, 2022Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Pu Yao, Qingyu Miao, Jiying Xu, Wei Wang, Jie Chen

Patent number: 10285073Abstract: Embodiments of the present disclosure provide a cell configuration method in a wireless network with a plurality of carriers. The method is performed at a base station of the wireless network. The method comprises generating a common cell from a first plurality of sectors at a first carrier of the plurality of carriers and identifying one or more high-traffic sectors from a second plurality of sectors at a second carrier of the plurality of carriers by monitoring a traffic volume of each of the second plurality of sectors. Each of the identified high-traffic sectors has the traffic volume higher than a predetermined threshold. The method also comprises generating one or more independent high-traffic cells from the one or more high-traffic sectors. The first plurality of sectors at least partially overlaps with the second plurality of sectors. Correspondingly, there is also provided an apparatus for cell configuration in a wireless network with a plurality of carriers.Type: GrantFiled: June 2, 2015Date of Patent: May 7, 2019Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Jiying Xu, Yang Tian, Min Huang, Feng Li

Publication number: 20040258813Abstract: The present invention relates to a method for processing tea tree product, in particularly, a method for processing tea flower. The process comprises of the following steps: picking, dehydrating, steaming, drying, quick-freezing and pulverizing of the tea flowers. The picking step is preferably carried out in the time interval beginning from 2-3 days before the pollination of the tea flower to 2-3 days after the pollination of the tea flower. Hollow baskets made of bamboo or plastics are used to accommodate the picked tea flowers during the picking and the said tea flowers must be immediately graded and spread. In the dehydrating step, the said tea flowers should be spread at a thickness of 2-5 cm on bamboo mat or cement floor and should be gently turned over once every 1 hour. The time of dehydrating for the spread fresh flowers does not exceed 10 hours and the most preferred spreading time is 6 hours. Having been dehydrated, the tea flowers are steamed.Type: ApplicationFiled: August 16, 2004Publication date: December 23, 2004Inventor: Jiying Xu
