  • Patent number: 10595290
    Abstract: A procedure for synchronization of re-configuration of RRC procedures between the radio base station and the UE is achieved by associating a new configuration to be used by a UE with an additional UE identity. The UE is normally identified by a first UE identity, but is informed in a re-configuration message that the UE also has the additional UE identity. The UE is identified by the additional UE identity when the new configuration is to be activated. Hence, when the radio base station detects that the UE responds to requests, which included the additional UE identity, the radio base station can conclude that the UE has activated the new configuration.

  • Patent number: 10187837
    Abstract: A mobile station is configured to support handover from a source base station to a target base station. The mobile station receives signaling from the target base station that indicates Packet Data Convergence Protocol (PDCP) protocol data units which have been successfully received at the target base station. In response, the mobile station generates further PDCP protocol data units for missing PDCP service data units from corresponding PDCP service data units buffered at the mobile station. The generating comprises using a different header compression state from that which was used for the missing PDCP service data units and ciphering specific to a connection with the target base station. The mobile station transmits the further PDCP protocol data units to the target base station.

  • Publication number: 20180123740
    Abstract: A user equipment unit (30) and a base station node (28) which is configured for operation with a synchronous HARQ protocol and with capability of sending data on an E-DCH channel either (1) in a nominal mode in single transmission time intervals of a predetermined length, or (2) in an extended mode in a pseudo transmission time interval. The pseudo transmission time interval comprises a first transmission time interval in which the data is transmitted and a second transmission time interval in which the data is re-transmitted. The second transmission time interval is consecutive to the first transmission time interval, and the first transmission time interval and the second transmission time interval are each of the (same) predetermined length.

  • Patent number: 9918307
    Abstract: UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8?n) bits, where n=the number of bits in C/T field.
