摘要： Methods and arrangements for adjusting timing of transmissions in a radio communication system in which aggregation of component carriers is employed are disclosed. A base station sends a first TA command applicable to a first component carrier to a user equipment. A need to maintain different uplink transmission timing for the first user equipment component carrier and second uplink component carrier is detected by the base station. The base station then sends a second TA command based on the detected need to maintain different uplink transmission timing. The second TA command is applicable to uplink transmissions on the first component carrier and/or the second component carrier. The user equipment adjusts uplink transmissions on the first component carrier and/or the second uplink component carrier based on the second timing advance command.

摘要： The present invention relates to method and arrangements for using an identifier of a predefined type, e.g. an RNTI identifying one configuration on an out-band control channel for activating the configuration identifiable by that identifier. The identifier is sent from the network to the UE, when a configuration corresponding to that identifier is to be activated. This implies that both the UE and the radio base station comprise a mapping between each configuration and the corresponding identity of each configuration.

摘要： A method for sending buffer status information includes checking if a quality of service (QoS) parameter is defined for a first logical channel and at least one condition of the set of predetermined conditions associated with a logical channel group is fulfilled. If the QoS parameter is defined and at least one condition of the set is fulfilled, the method includes setting a number of bits in a media access control header according to a first semantic. The bits carry buffer status information, and the first semantic—is based on the QoS parameter of the first logical channel. Otherwise, the method includes setting the number of bits carrying the buffer status information according to a second semantic that is based on an amount of data available for transmission across the logical channel group.

摘要： In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.

摘要： 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.
