    摘要： This disclosure provides a Scheduling Request transmission method (10) for decoupled downlink-uplink in heterogeneous network, where the heterogeneous network comprises at least two cells in charge of downlink and uplink transmission separately and connected with any backhaul, the method comprising: determining (11) a positive Data Scheduling Request, D-SR, is to be transmitted in a current D-SR's subframe together with HARQ-ACK/NACK on PUCCH using PUCCH format 1a/1b/3; transmitting (12) a HARQ-ACK/NACK in the current D-SR's subframe on PUCCH together with a negative D-SR using PUCCH format 1/1a/1b or format 3 while transmitting a Scheduling Request, SR, in a next SR's subframe subsequent to the current D-SR's subframe. In this method, the Scheduling Request (SR) of the UEs can be correctly detected in the Pico base station to trigger UL transmission in decoupled UL/DL scenario in various case and any kinds of backhaul can be supported.

    摘要： The invention relates to a method (20) in a device-to-device, D2D, enabled user equipment (12) of a communication system (10). The D2D enabled user equipment (12) supports D2D-communication with another D2D-enabled user equipment (15). The communication system (10) comprises a base station (15) serving one or more cellular user equipment (14) unable to support D2D communication. The D2D enabled user equipment (2, 15) and the cellular user equipment (14) share the same communication resources. The method (20) comprises: receiving (21), from the base station (13), configuration parameters comprising information on a reference signal pattern for use by the D2D enabled user equipment (12), and transmitting (22), based on the configuration parameters, cellular reference signals, enabling the cellular user equipment (14) to measure and report, to the base station (13), channel information on a channel from the D2D enabled user equipment (12) to the cellular user equipment (14). The invention also relates to D2D user equipment, methods in a base station, base station, computer programs and computer program products.

    摘要： A method, a user equipment, base stations for performing random access procedures in a network including a high power base station, a low power base station and a user equipment are provided, wherein the user equipment is in connection with the high power base station in a downlink direction and is in connection with the low power base station in an uplink direction. The method comprises performing, by the user equipment, the random access procedure with the low power base station if the random access procedure is initiated by the user equipment. The method further comprises performing, by the user equipment, the random access procedure with the high power base station if the random access procedure is initiated by the high power base station. With the present invention, the duration of the random access procedure conducted under the decoupled downlink/uplink scenario can be significantly shortened.

    摘要： The present disclosure relates to a method of radio communication between a first radio device and a second radio device using a first frequency resource and a first communication protocol by means of a network node, at least one of the radio devices being served by said network node. The method comprises determining a second frequency resource to use for non-network assisted device-to-device (D2D) communication between the first and second radio devices in case of a radio link failure between said at least one radio device and the network node. The method also comprises determining a second communication protocol to use for the non-network assisted D2D communication between the first and second radio devices in the case of a radio link failure between said at least one radio device and the network node.

    摘要： The present application relates to a DRX method in a CoMP scenario. In one embodiment, the DRX method comprises steps of detecting a new transmission on a Physical Downlink Control Channel (PDCCH) of one of at least two Base Stations (BSs) each of which is serving the UE; and triggering a DRX thread for continuously monitoring the PDCCH of the one BS on which the new transmission is detected. There is also provided a user equipment using the DRX method.
