Publication number: 20190273576Abstract: Various communication systems may benefit from improved transmissions. For example, a network transmission may benefit from improved throughput and efficiency in non-schedule multiple access communications. A method includes selecting at a user equipment operating in a non-scheduled access scheme at least one of a first codeword or a second codeword based on an amount of data. The data in the non-scheduled access scheme can be spread according to a spreading sequence. The method also includes determining a transport block size for at least one of the first codeword or the second codeword. In addition, the method includes transmitting the data from the user equipment to a network node using at least one of the first codeword or the second codeword.Type: ApplicationFiled: May 26, 2016Publication date: September 5, 2019Inventors: Yuantao Zhang, Zhuyan Zhao, Jingyuan Sun, Hongchao Li, Deshan Miao, Yanji Zhang, Klaus Ingemann Pedersen, Mihai Enescu

Publication number: 20190239251Abstract: Systems, methods, apparatuses, and computer program products of preamble sequence management for contention based access are provided. One method may include a user equipment sending a contention based access (CBA) request message, such as a random access procedure (RACH) message, to a network node (e.g., a base station or eNB). The CBA request message may include an indication that the user equipment wants to obtain a preamble for CBA data transmission and is not for full network access. The method may then include receiving an allocation of a preamble for CBA from the network node.Type: ApplicationFiled: July 4, 2016Publication date: August 1, 2019Inventors: Zexian Li, Yuantao Zhang, Yanji Zhang, Juha Sakari Korhonen

Publication number: 20190021134Abstract: A user equipment (UE) and a network access node (eNB or CIoT-BS) each store in their local memory the UE's context. Automatically upon a designated communication between them a timer is initiated that indicates the UE context is valid. For transitioning the UE from an idle to a connected mode, there is a selection between a first and a second procedure and this selection is based on the timer and on at least one other prescribed validity criterion (for example, context validity area, radio conditions or CE level). Data is then sent or received on a radio connection that is obtained via the selected first or second procedure, where only one of the first and second procedures utilizes the stored UE context. During that procedure, in an embodiment the UE can send to the CIoT-BS an indication that it has the stored UE context.Type: ApplicationFiled: January 8, 2016Publication date: January 17, 2019Applicant: Nokia Technologies OyInventors: Yanji ZHANG, Jussi-Pekka KOSKINEN, Sean KELLEY, Hannu Petri HIETALAHTI

Patent number: 7647421Abstract: A method and apparatus for controlling header compression and decompression for a link of a packet data network, wherein a predetermined header extension size for the link is initially set, and wherein a packet which will not be used as reference for subsequent decompression is transmitted from the compressor to the decompressor, if an extension header list of a size larger than the predetermined header extension size has been received. At the decompressing side, the transmission of an acknowledgement is suppressed, if an extension header list of the size larger than a predetermined header extension size configured at the decompressor has been received. Thereby, inconsistency of compression context between compressor and decompressor is prevented and a higher compression efficiency is achieved since there is no need to repair the context and correctly decompressed packets can be delivered to upper network layers without discarding any packets.Type: GrantFiled: August 20, 2002Date of Patent: January 12, 2010Assignee: Nokia CorporationInventors: Yanji Zhang, Keijo Harju
