    摘要： A method of operating a terminal node (310) configured to communicate with one or more network nodes using a re-configurable relaying device (330), RRD, is provided. The RRD is re-configurable to provide spatial filters, each one of the spatial filters being associated with a respective spatial direction into which incident signals are selectively transmitted by the RRD. The method comprises receiving (6002) a plurality of positioning reference signals, PRSs, transmitted by the one or more network nodes, and, upon a first PRS (363) and a second PRS (362) of the plurality of PRSs being received from a same network node (320) of the one or more network nodes, the first PRS (363) being received along a path which is relayed at the RRD (330): transmitting (6006) a measurement report message comprising positioning information for the terminal node (310) based on at least the first PRS (363) and second PRS (362).

    摘要： Examples provide a method of operating a first communication node (CN), wherein the first CN is configured for controlling a re-configurable relaying device (RRD), the RRD being re-configurable to provide spatial polarization filtering, the spatial polarization filtering being associated with an input spatial direction from which incident signals on a radio channel are accepted and with an output spatial direction into which the incident signals are transmitted by the RRD with configurable output polarizations set by the spatial polarization filtering, the method comprising providing, to the RRD, a control message indicative of predefined measurement spatial polarization filters; providing, to a second CN, a message requesting the second CN to transmit first reference signals associated with the predefined measurement spatial polarization filters, and receiving, on the radio channel from the second CN, first reference signals associated with the predefined measurement spatial polarization filters indicated by said control message, for estimation of channel matrices. Further, examples provide a method of operating a second CN and an RRD as well as corresponding first CNs, second CNs and RRDs.

    摘要： A method of operating a wireless communication device (or, simply device) is provided. The wireless communication device is configured for communication with a wireless communications network in a disconnected operational mode. The method comprises: monitoring for at least one wake-up signal included in a beam-swept burst of multiple wake-up signals in the disconnected operational mode prior to a paging occasion included in a beam swept burst of multiple paging occasions, wherein the at least one wake-up signal enables the wireless communication device to synchronize with the wireless communications network, and wherein the at least one wake-up signal is indicative of at least one time-frequency resource element of the paging occasion allocated to a paging indication that is transmitted using the same downlink transmit beam as the at least one wake-up signal; and responsive to detection of the at least one wake-up signal, monitoring the at least one time-frequency resource element of the downlink transmit beam where the wake-up signal was detected for a paging indication based on the detected at least one wake-up signal, wherein the detected at least one wake-up signal enables the wireless communication device to receive the paging indication without first monitoring for a synchronization signal block.

    摘要： A method of operating a wireless communication device (102) configured to communicate with a communications network (100) using frequency duplex transmission in an uplink frequency band (601) and in a downlink frequency band (602) is provided. The method includes monitoring for first downlink reference signals (445, 6052) transmitted by an access node (101) of the communications network (100) in the uplink frequency band (601) and using multiple first downlink transmit beams (351-354); and monitoring for second downlink reference signals (411, 446) transmitted by the access node (101) of the communications network (100) in the downlink frequency band (602) and using multiple second downlink transmit beams (361-364).

    摘要： According to a first aspect, examples provide a method of operating a first communication node (CN) wherein the first CN is configurable for transmitting, to a second CN on a radio channel, orthogonal frequency-division multiplexing (OFDM) symbols via a first propagation path and a second propagation path, wherein each OFDM symbol comprises a prefix, in particular a cyclic prefix, wherein transmitting the OFDM symbols via the first propagation path comprises transmitting the OFDM symbols to the second CN via a coverage enhancing device, wherein the method comprises providing, to the CED, a message indicative of a delay which is to be applied, by the CED, to incident signals, wherein the first CN selects the delay which is to be applied, by the CED, to the incident signals, to result in an arrival, at the second CN, of a first signal portion transmitted via the first propagation path of a first OFDM symbol being aligned with an arrival, at the second CN, of a second signal portion transmitted via the second propagation path of a second OFDM symbol. Further, a method of operating a second CN as well as a first CN and a second CN are provided.
