摘要： A Method and arrangement for determining the position of mobile terminals in a cell of a mobile communication network where time alignment (TA) is employed for terminal transmissions in timeslots to a serving base station. First, the distance to the base station is determined (200) for at least one mobile terminal in the call using a TA independent positioning method.A current TA value used by the at least one mobile terminal for time alignment of signal transmissions in an allocated timeslot, is also obtained (202).A relation between the determined TA independent distance and the obtained current TA value for each mobile terminal, is then estimated (204), and a TA bias of the cell is determined (206) based on the estimated relation. The position of any subsequent terminals can then be determined using a TA based positioning method and the TA bias,such that the current TA value used by the subsequent terminal is adjusted by the TA bias. Thereby, the TA based positioning method will become more closely related to the true terminal position.

摘要： Random access preamble detection for propagation delay is described herein. The proposed solution predicts energy levels for a set of hypotheses, compares the predicted energy with measured energy, and selects the hypothesis that minimizes a cost function based on the difference of the predicted energy and the measured energy. Some embodiments of the proposed solution may make it possible to extend cell range by allowing a maximum round-trip time exceeding the period of the random access preamble sequence. For the long preamble formats for Long Term Evolution (LTE) and New Radio (NR), the cell range may be extended beyond 120 kilometers (km). For millimeter wave applications, the cell range may be extended beyond 2.5 km.

摘要： There is provided mechanisms for CSI reporting on protocol layer 2. A method is performed by a wireless device. The wireless device is served by an access network node on a serving beam. The wireless device is configured with event conditions as to when to provide the CSI reporting to the access network node and with reporting configuration as to how to provide the CSI reporting to the access network node. The method comprises obtaining CSI values by monitoring candidate beams in which reference signals are transmitted by the access network node. The method comprises determining, based on comparing the CSI values to the event conditions, that at least one of the event conditions for CSI reporting is fulfilled. The method comprises sending the CSI reporting to the access network node as a protocol layer 2 CSI report and in accordance with the reporting configuration.

摘要： A method performed by a network node for controlling a maximum number of Random Access (RA) preambles for the network node to handle concurrently in a first cell in a wireless communications network is provided. A runtime parameter associated with the network node restricts the network node to handle at most a first maximum number of RA preambles concurrently. The network node monitors (401) load characteristics. The load characteristics are associated with the first cell. When the load characteristics fulfil a triggering condition, the network node selects (402) a second maximum number of RA preambles to be handled concurrently by the network node. The second maximum number is selected such that a probability value fulfils a threshold. The probability value is associated with a probability that RA preambles that are to be concurrently transmitted in the first cell will exceed the second maximum number of RA preambles. The network node adjusts (403) the runtime parameter to restrict the network node to handle at most the second maximum number of RA preambles concurrently.

摘要： A method performed by a network node for restraining false preamble detections in a Random Access, RA, procedure from a User Equipment, UE, to a first Transmission and Reception Point, TRP, in a multi TRP cell in a wireless communications network. The multi TRP cell comprising a set of TRPs. The network node calculates (602) an average coverage range per TRP in the set of TRPs based on an obtained coverage range for each respective TRP out of the set of TRPs. The network node determines (603) an adjustment parameter, such that the adjustment parameter multiplied with the calculated average coverage range is below a first threshold. The network node determines (604) a parameter related to a preamble detection zone. The parameter is based on: The adjustment parameter and the calculated average coverage range. The parameter is further based on any one or more out of: A false preamble detection rate according to historical data, and a success rate for RA according to historical data. The network node configures (606) the respective TRPs in the set of TRPs to use the determined parameter related to the preamble detection zone, in order to restrain false preamble detections in the RA procedure between the UE and the first TRP.
