摘要： A method is provided for determining a location of a mobile device (130) in a wireless network. The method includes receiving global navigation satellite system (GNSS) (141-144) measurements from the mobile device, and receiving terrestrial measurements from corresponding transceivers (111-114) in the wireless network, each terrestrial measurement indicating a distance between the corresponding transceivers and the mobile device. The method further includes selecting at least one terrestrial measurement having an uncertainty value within a predetermined accuracy threshold. The location of the mobile device is determined as a function of the GNSS measurements and the selected terrestrial measurement.

摘要： Methods and apparatus for selecting component carriers for random access attempts. A user equipment arranged to communicate with the base station over multiple component carriers, selects a component carrier from the multiple component carriers, based on a likelihood, and transmits a random access attempt to the base station over the selected component carrier. After maintaining statistics of component carriers selected for random access attempts per component carrier of the multiple component carriers, the user equipment adjusts the likelihood of selecting a specific component carrier for a subsequent transmission of a random access attempt based on the maintained statistics.

摘要： A mobile terminal receives, over a first cell configured on a carrier frequency, at least one parameter associated with a second cell configured on a carrier frequency. The at least one parameter comprises a cell identity. The mobile terminal then derives at least one physical layer characteristic for the second cell based on the received at least one parameter. Thereby, the mobile terminal is able to receive transmissions over the second cell, even if it could not initially detect the presence of the cell.

摘要： According to the present invention, a receiving node of a telecommunications network (20) (e.g. a radio base station (22) in uplink, or a mobile terminal (24) in downlink) transmits a single acknowledgement message to a transmitting node (e.g. a mobile terminal (24) in uplink, or a radio base station (22) in downlink) in respect of signals received over a plurality of frequency-aggregated carriers (component carriers) (10) between the transmitting and receiving nodes. If all signals are decoded correctly in the receiving node, a positive acknowledgement message (ACK) is sent to the transmitting node; if not all signals are decoded correctly, a negative acknowledgement message (NACK) is sent, or no acknowledgement message is sent. In this way, a single acknowledgement message can be sent for signals received over multiple carriers. The acknowledgement message can have the same format as legacy standards (for example, as specified in Release 8 of the 3GPP specifications), providing compatibility with existing equipment. The number of messages is also reduced compared with the straightforward approach of transmitting individual acknowledgement messages per component carrier.

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.

摘要： Measurement event evaluation is of interest in a user equipment (UE) configured with multiple downlink component carriers (CCs). The UE performs measurements of a neighbor and a specific one of the configured CCs, being used as a reference CC. The UE evaluates, based on the measurements of the neighbor and the reference CC, being a specific one of the configured CCs, an evaluation criterion for triggering a measurement report from the UE. In this way, the number of event evaluations and measurement reports can be reduced, since a specific reference CC is used for the purpose of measurement event evaluation in a scenario when the UE is configured with multiple CCs.

摘要： The present invention relates to a method and an arrangement for reducing a state transition time from a power saving state for a user equipment (18) in a communication network. The state transition time is reduced by retaining in the user equipment (18) one or more information parameter, such as the radio network temporary identifier for a high speed downlink shared channel (H-RNTI), when performing a state transition to said power saving state so as to enable a time reduction when said user equipment switches back from said power saving state.

摘要： The present invention relates to methods and a transmitter and a receiver for a mobile communication system. The basic idea of the present invention is to recursively derive from previous HARQ feedback the number of HARQ transmissions that is required to be able to decode the transmitted data successfully and to only transmit explicit HARQ feedback information if the decoding result differs from the derived result.

摘要： The invention relates to a method in a user equipment 4 for determination of timing of a Hybrid Automatic Repeat re-Request, HARQ, response. The user equipment 4 operates in a communication network 1 comprising a primary radio access technology system 2 and a secondary radio access technology system 3. The user equipment 4 receives on at least one downlink carrier on the first radio access technology system 2 and on at least one downlink carrier on the second radio access technology system 3. The method comprises determining a downlink timing related to the secondary radio access technology system 3; determining a virtual uplink timing for HARQ response on the secondary radio access technology system 3 based on the downlink timing; determining an uplink timing related to the primary radio access technology system 2; and determining, based on the virtual uplink timing and the uplink timing for the primary radio access technology system 2, an uplink time instance for transmission of the HARQ response on an uplink carrier of the primary radio access technology system 2, wherein the HARQ response relates to data received on the downlink carrier on the secondary radio access technology system 3. The invention also relates to user equipment, radio base stations and methods therein.
