Publication number: 20220386385Abstract: Presented are systems and methods for transmission of preamble and payload messages in random access procedures. A wireless communication device may transmit, in a random access (RA) procedure, a RA preamble and a corresponding uplink channel payload to a wireless communication node. The wireless communication device may retransmit, to the wireless communication node, the corresponding uplink channel payload through an uplink grant, responsive to a failure of the transmitted uplink channel payload for the wireless communication node.Type: ApplicationFiled: August 12, 2022Publication date: December 1, 2022Inventors: Zhihong QIU, He HUANG, Eswar Kalyan VUTUKURI

Patent number: 11490257Abstract: A method for carrying out data integrity protection on a communication network. According to an implementation, a wireless communication device indicates, to a wireless network, the maximum data rate up to which integrity protection is supported for user plane data. A network node (e.g., a node of the core network, such as an SMF) receives this information and determines whether or not to enable integrity protection for user plane data based on the information (possibly in conjunction with other information such as the minimum data rate to be supported, etc.). The network node then communicates the decision to enable or disable integrity protection to a RAN node (e.g., a wireless base station).Type: GrantFiled: June 7, 2021Date of Patent: November 1, 2022Assignee: ZTE CorporationInventors: Eswar Kalyan Vutukuri, He Huang

Patent number: 9356785Abstract: A method and system for enhanced security for A5/1 encoding, the method including choosing, at a transmitter, bits within a layer 1 header of a slow associated control channel (‘SACCH’) message for randomization; and setting, at the transmitter, the chosen bits randomly prior to channel coding and encryption of the slow associated control channel message. Further the method may include choosing, at a transmitter, a number of bits to toggle after convolution coding of a message containing a slow associated control channel message, the number of toggled bits being sufficiently low to allow correction at a receiver; and toggling, at the transmitter, said bits based on the channel conditions of the message.Type: GrantFiled: August 15, 2013Date of Patent: May 31, 2016Assignee: BlackBerry LimitedInventors: Michael Eoin Buckley, Eswar Kalyan Vutukuri
