摘要:
A method in a second wireless device for handling relay assistance from a first wireless device in a wireless network is provided. The second wireless device sends (202) a first beacon signal to the first wireless device, which first beacon signal advertises that the second wireless device needs relay assistance in a radio communication, and/or the second wireless device receives (203) a second beacon signal from the first wireless device, which second beacon signal advertises that the first wireless device provides relay assistance in a radio communication in the wireless network. The second wireless device then configures (209) a Device to Device, D2D, bearer between the first wireless device and the second wireless device based on the first beacon signal and/or the second beacon signal. This enables said communication to be performed via the D2D bearer wherein the first wireless device acts as a relay node.

The present disclosure relates to a method and a network node 100 in a wireless communications network 1. In particular, it relates to selecting a frequency band for operation for user equipment 9 in the wireless communications network 1. The frequency band to be selected is either a licensed frequency band or an unlicensed frequency band. The network node 100 is a macro base station 5, or a home base station (7, 700), and is adapted to communicate with user equipments 9 in the wireless communications network 1 which comprises both the macro base station 5 and the home base station (7, 700). The home base station (7, 700) is adapted to support operation in both the licensed frequency band and the unlicensed frequency band. The method comprises obtaining radio condition measurements performed on the licensed frequency band and/or on the unlicensed frequency band; selecting the frequency band, based on the obtained radio condition measurements; and updating the home base station of the selected frequency band to be used for communication with one or more of the user equipments.

The present solution relates to a method in a user equipment (110) for providing navigation signals to a navigator device (104) for use in determining the location of the navigator device. The user equipment (110) selects a plurality of satellites whose signals are to be emulated. After determining the position of the user equipment (110), the user equipment (110) translates the determined position to emulating navigation signals using a parameter derived from each of the respective selected satellites. The user equipment (110) transmits, to the navigator device (104), the emulated navigation signals. The emulated navigation signals enable the navigator device to determine the location of the navigator device (104).

A system (100) may include a source node (122-1 ) to collect radio resource management (RRM) information, determine that a handover is to be initiated for user equipment (UE), and send, in response to the determination that a handover is to be initiated, a handover request message that includes the RRM information. The system may further include a target node (122-2) to receive the handover request message from the source node, identify, in response to receiving the handover request message, current network information for the target node, generate handover feedback information for the UE based on the RRM information and the identified current network information, and send a handover response message to the source node, the handover response message including the generated handov er feedback information, the generated handover feedback information assisting the source node in making a decision regarding the handover.
摘要:
A method and apparatus related to a first radio network node serving a first UE in a first mobile radio network for enabling a D2D communication with a second UE served by a second radio network node in a second radio network. The first radio network node establishes a connection with the second radio network node. The first UE (230) requests to the first radio network node to enable a communication with the second user equipment (290). The first radio network sends a first message comprising information related to the first UE (230) to the second radio network node (280) for configuration of the second UE (290). The first radio network node receives a second message for configuration of the first UE (230) and sends to the first UE (230) a third message related to the second UE.
摘要:
A method in a network node for assisting a first user equipment in interference mitigation. The network node is comprised in a cellular communications network. The cellular communications network further comprises the first user equipment and a second user equipment. The second user equipment causes interference to the first user equipment when at least one of the first user equipment and second user equipment communicate by using Device-to-Device communication. The network node obtains information about the receiver of the first user equipment. The network node then determines one or more parameters required by the first user equipment for mitigating the interference. The parameters relate to the obtained information and to the interfering second user equipment. The network node then sends the one or more parameters to the first user equipment thereby assisting the first user equipment to mitigate interference caused by the second user equipment.
摘要:
Parameters that define the frequency raster points to be used in an unlicensed band are used to support operation of wireless devices in both licensed and unlicensed frequency bands. Corresponding signaling messages are used to exchange information regarding the device's capabilities, preferences, transmission power, etc. In one method, implemented in a wireless communication device (410) configured to operate in at least first and second frequency bands, a radio access network is accessed (510), using a first radio access mode and the first frequency band. The method further comprises transmitting (520) frequency raster data to the radio access network, wherein the frequency raster data corresponds to the second band, indicates a tuning capability of the wireless communication device (410), and comprises at least a first frequency index and a granularity indicator. Methods and apparatus for maintaining a database of access point capabilities in unlicensed bands are also disclosed.

Methods and arrangements (400, 600) in network nodes (101, 102, 110) for controlling radio emission from a mobile terminal (102) are provided. The mobile terminal (102) is located in a critical area. The network node sends a location parameter of the critical area, wherein the location parameter indicates a geographical location of the critical area. The first radio network node (101, 110) sends a first set of control parameters to the mobile terminal. The mobile terminal determines a geographical location of the mobile terminal and controls radio emission from the mobile terminal based on the first set of control parameters, the location parameter and the geographical location of the mobile terminal. Methods and arrangements (900) in a first radio network node (101, 110) for performing admission control are provided. The first radio network node (101, 110) receives a service request. In another step, the first radio network node (101, 110) denies the service request if an aggregated number of mobile terminals attached to the first radio network node (101, 110) exceeds a predetermined mobile terminal number or total received power at the first radio network node exceeds a predetermined threshold.
