摘要： A user equipment is configured to operate in a wireless communications network being operated in a TDD scheme, the TDD scheme including a plurality of TDD-frames, each TDD-frame including a guard period arranged between a downlink symbol and an uplink symbol of the TDD-frame. The user equipment is configured to receive a first number of symbols during the guard period or is configured to transmit the uplink symbol and to transmit a second number of symbols previous to transmitting the uplink symbol.

摘要： A transmitter includes a 3-dimensional antenna array including a plurality of antenna elements, each antenna element having a radiation pattern, wherein the radiation patterns mutually overlap. The plurality of antenna elements is adapted for coherent wireless communication in a wireless communication system. The 3D-antenna array includes first and second and third antenna elements spanning a 2-dimensional antenna plane, and includes a fourth antenna element arranged outside the 2-dimensional antenna plane; or the 3D-antenna array includes a first antenna element configured to direct a transmitted signal into a first direction, and a second antenna element configured to direct a transmitted signal into a second direction and not into the first direction. The transmitter further includes a precoder connected through the 3D-antenna array, to form one or more transmit beams and/or receive beams with the 3D-antenna array.

摘要： A receiver has a plurality of antennas and receives a plurality of radio signals from a plurality of transmitters of different cells of a wireless communication network. Each radio signal has a position reference signal sequence and is transmitted to the receiver via a radio channel including a plurality of path components. The receiver processes the radio signal to estimate for a path component the time of arrival of the PRS sequence and to determine for a path component a path strength value of the PRS sequence. A position of the receiver is estimated using the ToAs and the PS values.

摘要： The present invention is concerned with different novel concepts for reducing latency in data transmission. These concepts may be exploited by a transceiver configured to perform wireless data communication with a third party device by aggregating time division duplex carriers having different temporal distribution of uplink times and downlink times. These concepts may further be exploited by an apparatus configured to perform data transmission or reception via allocations of transmission resources of aggregated carriers in units of transmission time intervals into which the aggregated carriers are subdivided, wherein the aggregated carriers are temporally subdivided into the transmission time intervals in a temporal grid, respectively, wherein the aggregated carriers' grids are temporally mutually offset.
