Patent number: 10070428Abstract: In an aspect, a wireless terminal, operating in a wireless communication system with distinct areas that each include base stations, transmits a data packet to a network node on a common channel. The data packet includes a header with an identifier that is an area-specific identifier for the wireless terminal. The wireless terminal has been allocated an area-specific identifier but not a cell-specific identifier. A network node of the wireless communication system receives the data packet sent from the wireless terminal. The network node associates the area-specific identifier for the wireless terminal in the data packet with a network-wide identifier for the wireless terminal and handles the data packet according to the network-wide identifier.Type: GrantFiled: November 17, 2015Date of Patent: September 4, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Waikwok Kwong, Sofia Brismar, Fredrik Ovesjö, Jose Luis Pradas

Patent number: 10064214Abstract: A method and system to reduce a probability of incorrect interruption of an uplink transmission of a wireless device are disclosed. According to one aspect, decoding of a sequence of bits obtained from a signal received by the wireless device is performed without knowing whether the sequence corresponds to one of a grant for uplink transmission and noise. Decoding of the sequence of bits is performed to determine a probability metric associated with a first m bits of the sequence, where m is an integer greater than 1. The probability metric is compared to a threshold. The received signal is interpreted as having a grant sequence if the probability metric is greater than the threshold. The received signal is interpreted as noise if the probability metric is not greater than the threshold.Type: GrantFiled: March 31, 2015Date of Patent: August 28, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Stefania Sesia, Göran Bergman, Waikwok Kwong, Gerardo Agni Medina Acosta

Patent number: 9559827Abstract: A wireless device (105) for managing reporting of channel quality is configured to communicate with a mobile radio communication network (102). The wireless device (105) identifies (404) there being no downlink activity between the wireless device (105) and the mobile radio communication network (102). The wireless device (105) reduces (406), in response to the identification, a level of channel quality reporting when there is no downlink activity. In a multi Radio Access Bearer (RAB) scenario this supports reduction of a higher drop rate of multi-RAB, e.g. speech and data, compared to e.g. stand-alone speech RAB.Type: GrantFiled: December 23, 2013Date of Patent: January 31, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Waikwok Kwong, Jose Luis Pradas

Patent number: 9549408Abstract: The present disclosure concerns interference congestion control in radio communication networks. Disclosed herein are methods as well radio network nodes. A radio network node may, for example, estimate a neighboring cell interference. The radio network node may also detect a sudden significant increase in the estimated neighboring cell interference. In response to detecting a sudden significant in the estimated neighboring cell interference, the radio network node may also transmit a message to at least one other radio network node. This message may include an indicator indicating to said at least one radio network node to initiate an interference congestion control procedure. Hereby it is made possible to allow for interference congestion control in radio communication networks.Type: GrantFiled: March 14, 2013Date of Patent: January 17, 2017Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Torbjörn Wigren, Patrik Karlsson, Waikwok Kwong, Billy Hogan
