Abstract: The present invention relates to methods and apparatuses as well as a measurement report signal for reporting measurements on ranging signals (RS1-RS4) received by a mobile station from satellites (SV1-SV4) or calculating a position based on such measurements, wherein each of said ranging signal comprises a stream (201) of data bits (202) spread by a spreading code (203). After synchronizing (501) to data bit edges in the stream of data bits on a ranging signal, a position in time modulo the data bit length for said stream of data bits with respect to a selected point in time is measured (502). The measured position in time could be used by the apparatus performing the measurements on the received ranging signals for calculating (504) the position of the mobile station. Alternatively the apparatus could transmit (503) a wireless signal including data representing said measured position in time, allowing the mobile station position to be determined in another apparatus (101).

Abstract: Systems and methods are disclosed for power assised Radio Frequency (RF) Electric and Magnetic Field (EMF) average power control for a Radio Access Network (RAN) node of a cellular communications system. In one embodiment, a method of operation of a controller for a RAN node comprises computing an average total transmit power over a control period and computing an initial Physical Resource Block (PRB) limit for transmission of a Physical Downlink Shared Channel (PDSCH) for the cell based on a comparison of the computed average and a reference. The method further comprises determining whether power scaling is to be used, adjusting the initial PRB limit and providing the adjusted PRB limit and a power scaling indication to a scheduler associated to the cell if power scaling is to be used, and otherwise providing the initial PRB limit and an indication of no power scaling to the scheduler.

Abstract: A method performed by first network node for determining a number of paths in a communication between a second network node and a Wireless Device (WD) in a wireless communications network is provided. The first network node obtains (401) 5service requirements on a communication service provided to the WD. The service requirements comprise a latency requirement and error rate requirement. The first network node determines (402) the number of paths for the communication based on the obtained service requirements. Each path out of the number of paths, is to be scheduled for a respective replicated data transmission. The first network node determines (403) 10path specific operation target parameters for each respective replicated data transmission. The determination is based on the determined number of paths and the service requirements. The respective path specific operation target parameter comprises at least a (BLER) target and a maximum latency. The first network node sends (404) a request to the second network node. The request requests transmission of replicated data 15of each path of the number of paths, according to the path specific operation target parameters.20Publ.

Abstract: A method for kinematic state estimation of a UE (10) in a wireless communication system (1). The method comprises estimating of a kinematic state comprising two-dimensional position, two-dimensional velocity (14) and a frequency bias of the UE (10). The estimation is based on and fully enabled by obtained measurements of Doppler shifts (22A; 22B), relative two different antennas of the wireless communication system (1), of radio signals (12) transmitted from the UE (10), and obtained distance-establishing measurements (R) associated with the UE (10). A network node performing the method and a computer program therefore are also presented.

Abstract: There is provided mechanisms for controlling total average transmission power of a radio base station. A method is performed by a control device. The method comprises performing, for a current discrete time value t, control of total average transmission power { P tot } (t) of the radio base station according to a back-off power control loop. The total average transmission power { P tot } (t) is computed over an averaging time window T of the present value of momentary transmission power and the N — 1 values of momentary transmission power preceding the present value of momentary transmission power. The method comprises evaluating, for a future discrete time value less than, or equal to, t + T , the total average transmission power, assuming that values of momentary transmission power for all discrete time values from t up to t + T , starting at the next discrete time value t + 1, is limited to a minimum value of said momentary transmission power. The method comprises limiting the momentary transmission power to the minimum value for at least the next future discrete time value when the evaluated total average transmission power, for any of the future discrete time values, exceeds a power threshold value based on a regulatory limit.

Abstract: A method for transmission control in a multi-connectivity communication system comprises obtaining (S1) of an indication of decreased data rate through a first transmitting node of a multi-connectivity communication system. At least a subset of packets, originally scheduled for, and buffered in, the first transmitting node is rescheduled (S2) to at least one second transmitting node, different from the first transmitting node, of the multi- connectivity communication system, in response to the obtaining of the indication. A network node for transmission control is also disclosed.

Abstract: A method for generating a probability map for a cell served by a network node is provided. The method includes generating a first probability map (P1) indicating a likelihood of primary beam directions (step 602). Generating the first probability map includes recording a first direction of a first user equipment (UE), the first direction indicating a direction of a first beam (e.g., a first set of antenna weights (a.k.a., precoding vector)) associated with the first UE when the first UE appears in the cell served by the network node. The method further includes generating a second probability map (P2) indicating a joint likelihood of primary and secondary beam directions (step 604). Generating the second probability map includes recording a second direction of a second beam associated with the first UE when the first UE switches from the first beam to the second beam, the second direction being recorded in association with the first direction. 28 3602-1538WO1 (P73007WO1)

Abstract: A method is provided for monitoring beam quality in a cell served by a network node. The method includes the network node communicating with a user equipment using a first beam (e.g., a first set of antenna weights (a.k.a., precoding vector)). The method further includes determining a change in a signal measurement with respect to the first beam over a time period T (S T ). The method further includes determining a maximum value of the signal measurement with respect to a second beam over the time period T (S secondary,max ). The method further includes determining whether a condition is true, wherein determining whether the condition is true comprises: i) determining whether S T is less than a first threshold (th 1 and ii) determining whether S secondary,max is greater than a second threshold (th 2 ). The method further includes, in response to determining that the condition is true, triggering a switch to the second beam.
