摘要:
The disclosure relates to a method in a mobile terminal for communication with a base station in a wireless network during a random access procedure. The method comprises exchanging (202) between the mobile station and the base station, during the random access procedure, information on a selected DRX scheme to be used for communication between the mobile terminal and the base station in the random access procedure, setting (204) the mobile terminal in DRX mode according to the selected DRX scheme and receiving (206) at least one message from the base station during the random access procedure, wherein the at least one message was transmitted according to the selected DRX scheme. The disclosure also relates to a corresponding method in a base station, and to a mobile terminal and a base station. By such methods, base station and mobile terminals, battery power in a mobile terminal may be saved during a random access procedure.

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, apparatus, and computer program for selecting a communication mode for a terminal device is described herein. A communication mode is selected for a terminal device on the basis of a difference between an estimated radio channel between the terminal device and a base station and an estimated radio channel between the terminal device and another terminal device. The communication mode is selected from a group comprising a plurality of different configurations to multiplex communication over the first radio link with communication over the second radio link.
摘要:
A method performed in a radio network for determining a resource allocation between downlink and uplink for use in a radio interface between a radio network node and at least one mobile communication terminal in a mobile communication network. The method includes determining content types of a first established channel over the radio interface and of a second established channel over the radio interface, respectively. Downlink-to-uplink indicators associated with the respective content types are obtained. Resource usages of the first established channel and the second established channel, respectively, are obtained. Using the downlink-to-uplink indicators and the resource usages, a combined downlink-to-uplink ratio is determined. The combined downlink-to-uplink ratio is applied. A corresponding network node, computer program and computer program product are also presented.

Methods, apparatuses, a system and computer program products are provided for autonomously reusing an unlicensed band in a hybrid cellular and device-to-device network. In accordance with an embodiment of the invention, an apparatus receives a request for resources from a terminal, and identifies available resources on an unlicensed band based on the request. The apparatus further reserves the identified available resources for use by the terminal, and transmits a reservation response to the terminal, wherein the reservation response comprises information relating to the reserved available resources. Further, the apparatus transmits data to the terminal over a licensed band and the available resources reserved on the unlicensed band.
摘要:
In accordance with an example embodiment of the present invention, an apparatus is configured to receive a first signaling message comprising a first identifier of a first node and a second identifier of a second node, and responsive to the receiving initiate at least one policy action relating to at least one of the first node and the second node; and transmit a second signaling message to the first node, the second signaling message being configured to cause bearer establishment between the first node and the second 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.
摘要:
The present disclosure relates to a method of a first radio device in non-network assisted device-to-device (D2D) communication with a second radio device using a first frequency resource and a first communication protocol. The method comprises determining that the first radio device is within coverage of a cellular network. The method also comprises connecting to the cellular network. The method also comprises sending a message to the second radio device, informing said second radio device that the first radio device is within coverage of the cellular network. The method also comprises receiving a message from the cellular network comprising information about a second frequency resource and a second communication protocol. The method also comprises initiating a handover of the D2D communication from the first frequency resource and communication protocol to the second frequency resource and communication protocol.
摘要:
A UE, an RBS and respective methods therein for managing uplink resources from an RBS in a wireless communication network are provided. The method in the UE comprises determining that uplink resources are needed, and determining which type of service for which the uplink resources are needed. The method further comprises transmitting, to the RBS, a scheduling request for a scheduling grant, the scheduling request comprising an indication of the type of service for which the scheduling grant is requested.
摘要:
The present invention comprises an apparatus and method supporting handover of mobile relay nodes, “RNs” (56), in a wireless communication network (60), in a manner that advantageously differentiates handling of control- and user-plane connections of the wireless communication devices (58) supported by the RN (56). Rather than conventionally anchoring the control-plane connections of relay-connected UEs (58) at the donor radio base station (54-1) supporting the RN (56), the donor radio base station (54-1) includes or is communicatively linked to an anchor node (100) that, from the perspective of the involved control plane entity or entities (70) in a supporting Core Network, “CN” (68), anchors those connections. The anchor node (100) facilitates handover between donor radio base stations (54-1, 54-2) such that the control-plane connections are retained at the anchor node (100) while the user-plane connections are switched to the target radio base station (54-2) receiving the RN (56) in handover.
