    摘要： The present disclosure relates to a network node, a network control node, a wireless device and corresponding methods for optimized broadcasting of system information messages in a wireless network. The disclosure proposes a method, performed in a wireless device, of assessing system information perception capability in a wireless network that is arranged to broadcast system information on at least two frequency carriers. The method comprises receiving (S10) broadcasted system information on the at least two frequency carriers. The method also comprises determining (S12), using the received broadcasted system information, frequency carrier identity correlated information for each of the at least two frequency carriers. The method further comprises reporting (S14) receipt of the broadcasted system information on the at least two frequency carriers, wherein the report includes the frequency carrier identity correlated information.

    摘要： According to an aspect, there is provided a method of operating a first radio access node in a communication network, the first radio access node supporting a plurality of cells that are divided into one or more groups of cells, wherein at least a first group of cells comprises more than one cell, the method comprising determining (901) a first base key for a communication device that is to connect to the first radio access node via a first cell in the first group of cells; wherein the first base key is determined from an identifier for the first group of cells; using (903) the first base key to determine a first encryption key that is to be used to encrypt communications between the communication device and the first radio access node via the first cell; and in the event that the communication device is to connect to the first group of first radio access node via a second cell in the first group of cells, using (907) the first encryption key to encrypt communications between the communication device and the first radio access node via the second cell.

    摘要： Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. More specifically, in some embodiments, a statistics-assisted sCell selection process is utilized for sCell selection. This statistics-assisted sCell selection process improves the efficiency of sCell selection, particularly where there are multiple candidate sCells on multiple carrier frequencies.

    摘要： According to an aspect, one or more network nodes of a wireless communication system sends, to a wireless device operating in the wireless communication system, mobility reference signal (MRS) configuration information, the MRS configuration information specifying one or more parameters for each of a plurality of MRS configurations. The network node subsequently sends, to the wireless device, an activation command indicating that at least a first one of the MRS configurations is to be used by the wireless device, the activation command including an index identifying the first one of the MRS configurations from among the plurality of MRS configurations. The wireless device receives the MRS configuration information and the activation command. The wireless device searches for at least one MRS specified by the first one of the MRS, responsive to the activation command and performs at least one measurement on the at least one MRS.
