  • Publication number: 20170127422
    Abstract: A sending node sends information to a receiving node. Said nodes are comprised in a wireless communication network. Communication between said nodes is associated with a first cell. The sending node obtains predefined scrambling for scrambling the information and which predefined scrambling is specific for the first cell. The receiving node correspondingly obtains de-scrambling. The sending node sends, to the receiving node, the information repeatedly a certain number of times, wherein each time the information is sent it is scrambled differently based on the obtained scrambling. Each time the information is received by the receiving node it is de-scrambled differently based on the obtained de-scrambling.

  • Patent number: 9521673
    Abstract: A method for resolving a Temporary Block Flow (TBF) in a wireless network including one or more mobile stations exchanging data with a base station system. The method comprises receiving a RLC/MAC block and retrieving a first TFI in the RLC/MAC header. The TFI is compared to an assigned TFI. The capability for the associated MS to resolve TBFs based on extended TFI addressing is determined. If the received first TFI matches assigned TFI and represents a comprehensive TFI for the associated MS, the payload of the RLC/MAC block is decoded. When the first TFI matches assigned TFI value and is identified as a code point to an eTFI, at least a predetermined field of the RLC data block is decoded and an extended TFI, eTFI, is retrieved. The eTFI is compared with an assigned eTFI. Following a match, the payload of the RLC data block is decoded.

  • Publication number: 20160352466
    Abstract: Method performed by a transmitting device (101) for transmitting a block to a receiving device (102). The transmitting device (101) and the receiving device (102) operate in a wireless communications network (100). The transmitting device (101) transmits a block to the receiving device (102). The block comprises four bursts. The four bursts further comprise Uplink State Flag, USF, Stealing Flag, SF, and data and header fields. The USF and the SF fields are interleaved and mapped over the four bursts. The data and header fields are interleaved over one burst but repeated over the four bursts. The data and header fields are overlapping with and overridden by bits from the USF field in different positions in each burst. In a method performed by the receiving device (102), the receiving device (102) receives the transmitted block. In a method performed by a controlling node (140), the controlling node (140) selects a block format for transmission by the transmitting device.

  • Publication number: 20160134398
    Abstract: Embodiments herein relate to a method performed in a transmitting node (12) for transmitting at least one burst of energy to one or more receiving nodes (10,13) in a wireless communication network (1). The transmitting node (12) comprises a number of transmit antennas being more than one and wherein the at least one burst of energy carries a payload for one or more receiving nodes (10,13). The transmitting node (12) determines a shift, for one or more transmit antennas, in one or more signal characteristics of a burst of energy of the at least one burst of energy. The shift indicates one or more additional information bits, in addition to the payload, for a first receiving node (10). The transmitting node further transmits, over the one or more transmit antennas, the burst of energy of the at least one burst of energy with the shift in the signal characteristic carrying the payload to one or more receiving nodes (10,13) in the wireless communication network (1).

  • Patent number: 9232534
    Abstract: A method in a mobile station (120) for enabling more than eight mobile stations to share one uplink Packet Data Channel (PDCH) in a GSM network (100) is provided. A combination of Uplink State Flag values in a set of two or more downlink radio blocks is received. The received Uplink State Flag values of the combination are jointly interpreted. Packet data are only transmitted (706; 1402) when an assigned combination of Uplink State Flag values has been received. Conventionally in GSM only a maximum of 8 unique mobile stations can share one PDCH using one timeslot (of eight conventionally available). By the combination of the USF values and joint interpretation thereof, more than 8 unique mobile station can share the same PDCH. Compatibility is also enabled with legacy mobile stations supporting only a single USF value.

  • Patent number: 9094177
    Abstract: The invention relates to a method in a mobile network for resolving a Temporary Block Flow, a TBF, in a wireless network including one or more mobile stations exchanging data with a base station system. The packet data is transmitted by means of one or more RLC/MAC blocks each associated with the TBF. The TBF is identified by means of an Temporary Flow Identity, a TFI, and associated to an MS. The inventive method is applicable in a wireless communication system with an extended TFI addressing space. The method comprises steps of receiving a RLC/MAC block and retrieving a first TFI in the RLC/MAC header. The TFI is compared to an assigned TFI. The capability for the associated MS to resolve TBFs based on extended TFI addressing is determined. If the received first TFI matches assigned TFI and represents a comprehensive TFI for the associated MS, the payload of the RLC/MAC block is decoded.
