Patent number: 10785687Abstract: The application relates to the removal of one of the links in multi-flow HSPA but the proposed method is also applicable to normal HSDPA operation during handover. In particular the application aims at minimizing the negative impact of a removed radio link, i.e. drop of packets and/or delays. According to the proposed method, in which the radio link to be removed is via a first Node B NB1 (RL Removal Req), the NB1 ends the pending data transmission and informs the controlling RNC about the data which was not transmitted, in particular in the form of the lowest sequence number in its buffer. Subsequently, the RNC decides, based on this sequence number, which data packets need to be retransmitted on a second radio link via a second node B NB2, and instructs NB2 accordingly (Data Forwarding).Type: GrantFiled: July 10, 2012Date of Patent: September 22, 2020Assignee: Nokia Solutions and Networks OyInventors: Alexander Sayenko, Jani Matti Johannes Moilanen, Hans Thomas Hoehne, Isman Bazar, Karri Markus Ranta-Aho, Jeroen Wigard

Patent number: 10785801Abstract: Methods, apparatuses and computer program provide for random access in a wireless communication system. A method implemented in a network device comprises receiving, from a terminal device, a signal for initiating an RA procedure of a first RA type, the signal including a preamble portion and an information portion. In response to successfully detecting the preamble portion of the signal, but failure in detection of the information portion of the signal, transmitting to the terminal device a first response indicating a successful detection of only a preamble portion of the signal, or a second response indicating an RA procedure of a second RA type different from the first RA type. The described technique may increase the reliability of a two-step RACH procedure and/or reduce consumption of time-frequency resources.Type: GrantFiled: January 2, 2018Date of Patent: September 22, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Gen Li, Jinhua Liu, Rui Fan

Patent number: 10779352Abstract: The disclosure is related to a multi-gateway communication method. The method is applied to a wireless gateway system that includes multiple nodes including a number of gateways. A root gateway is provided among the gateways. When a gateway receives an uplink data from a node, the uplink data is transmitted to a backend server if the gateway is the root gateway. The uplink data is transmitted to a parent gateway if the gateway is not the root gateway. On the other hand, when the gateway receives downlink data from a node, it is determined if a destination node is recorded in a downlink routing table of a descendant gateway if gateway is not connected with the destination node but with the descendant gateway. If the destination node is recorded in the downlink routing table, the data is transmitted to the descendant gateway; otherwise, the downlink data is discarded.Type: GrantFiled: November 5, 2018Date of Patent: September 15, 2020Assignee: KIWI TECHNOLOGY INC.Inventors: Jian-Hong Liu, Chun-Yu Wang, Tsung-Chih Huang
