The present invention is designed to provide a user terminal, a radio base station and a radio communication method of novel structures that can achieve a good communication environment. A radio base station non-orthogonal-multiplexes downlink signals for a plurality of user terminals over a given radio resource, a user terminal having received the downlink signals for the plurality of user terminals decodes downlink signal for another user terminal, judges whether or not the downlink signal for the other user terminal has been successfully received, based on the decoding result of the downlink signal, reports a judgement result as to whether or not the downlink signal for the other user terminal has been successfully received and a judgement result as to whether or not a downlink signal for the user terminal has been successfully received, to the radio base station, and then the radio base station executes retransmission control of downlink signals based on reports from the user terminal.

User terminal, radio base station and radio communication method

A wireless telecommunication system comprises base stations for communicating with terminal devices. One or more base stations support a power boost operating mode in which a base station's available transmission power is concentrated in a subset of its available transmission resources to provide enhanced transmission powers as compared to transmission powers on these transmission resources when the base station is not operating in the power boost mode. A base station establishes an extent to which one or more base stations in the wireless telecommunications system support the power boost operating mode conveys an indication of this to a terminal device. The terminal device receives the indication and uses the corresponding information to control its acquisition of a base station of the wireless telecommunication system, for example by taking account of which base stations support power boosting and/or when power boosting is supported during a cell attach procedure.

Network architecture, methods, and devices for a wireless communications network

A user equipment, UE, (20) determines a mobility state of a Wi-Fi access point, AP, as one of a moving mobility state and a non-moving mobility state along with control information relating to UE cell (re-)selection and/or handover behavior based on the determined mobility state of the Wi-Fi access point, AP. The UE then controls its cell (re-)selection and/or handover behavior in relation to the Wi-Fi access point, AP based on the determined control information. In a preferred embodiment, the UE can communicate with a cellular base station, BS, and with the Wi-Fi access point, AP. The UE detects the Wi-Fi AP, determines that the Wi-Fi AP is moving based on a moving AP indication, and controls cell (re- Selection and/or handover behavior of the UE based on the determination that the Wi-Fi AP is moving along with other information.

Synchronization Time Difference measurements in OFDM Systems

Embodiments herein relate to a method in a wireless device (10) for performing a positioning measurement procedure in a radio communications network, which positioning measurement procedure is performed using at least uplink transmitted signals from the wireless device (10). The wireless device (10) obtains information related to a maximum power reduction applied, or a maximum power reduction expected to be applied on uplink signals transmitted from the wireless device (10), which uplink signals are used for performing at least one positioning measurement. The wireless device (10) further takes the maximum power reduction applied, or the maximum power reduction expected to be applied into account when performing the positioning measurement procedure related to the at least one positioning measurement and/or a radio transmission procedure involving uplink radio signals transmitted by the wireless device (10) to enhance positioning measurement performance of the positioning measurement procedure.

Wireless device, measuring node, network node, methods therein, computer program, and computer-readable storage medium

Conventional positioning methods based on measurements of wireless device transmissions may fail to account for adjustments to uplink transmit timing made by the wireless device. Problems caused by this failure may become even more severe when multiple timing advances are applied on different carriers, in multi-carrier operation where the carriers are non-co-located. One example method for handling timing measurements used for positioning, according to several of the techniques detailed herein, begins with obtaining (810) one or more timing measurement values for timing measurements performed on radio signals transmitted by a wireless device. Information related to one or more transmit timing adjustments applied to radio signal transmissions by a wireless device is also obtained (820). Finally, one or more of the timing measurement values are compensated (830) with a compensation value, based on the obtained information related to the one or more transmit timing adjustments applied by the wireless device.

Enhancing positioning with transmit-timing adjustment information

The invention provides a method and a network node for controlling configuration of measurements to be performed by a user equipment (150a, 150b) operating in a wireless communication system (101). A configured measurement corresponds to at least one reporting criteria and the user equipment (150a, 150b) is able to support a limited number of parallel reporting criteria. Measurements to be performed by the user equipment in parallel may be requested by different network nodes such as a positioning server (140) and an eNodeB (110a, 110b). By letting a network node, such as the positioning server (140) or the (eNodeB 110a, 110b), obtain information on measurements requested by another network node the network node is able to configure the user equipment with a set of measurements that does not exceed at least one predetermined threshold for parallel reporting criteria
