Abstract: Embodiments herein may relate to a method performed by a UE (10) for determining a start position of a SI window to acquire a SI message in a wireless communication network (1). One or more SI messages are scheduled using a first or a second list of scheduling information. The UE (10) determines, if the SI message is scheduled using the first list of scheduling information, the start position of the SI window based on a location of the SI message in the first list of scheduling information. The UE (10) determines, if the SI message is scheduled using the second list of scheduling information, the start position of the SI window by taking a received input parameter into account, wherein the received input parameter is indicating the start position of the SI window used for acquiring the SI message.

Abstract: Techniques for providing and receiving system information messages from a wireless network. An example method, in a user equipment, UE, comprises receiving (510) at least one segment of a segmented system information block, SIB, in a first cell and receiving (520) at least one other segment of the SIB in a second cell. The example method further comprises determining (530), based on information received from the wireless network, whether the at least one segment of the SIB received in the first cell can be concatenated with the at least one other segment of the SIB received in the second cell. The example method still further comprises concatenating (540) the at least one segment received in the first cell with the at least one other segment received in the second cell, to form the SIB, or discarding the at least one segment received in the first cell, depending on said information.

Abstract: A method, in a distributed unit (DU) of a base station comprising a central unit (CU) and one or more DUs, each DU serving one or more cells, comprises sending, to the CU, information indicative of capacity in the DU for sending segmented messages and/or indicative of a capability of the DU to send segmented messages. In some embodiments, the information is indicative of capacity in the DU for sending segmented Public Warning System (PWS) messages and/or indicative of a capability of the DU to send segmented PWS messages. In some embodiments, the method further comprises receiving, from the CU, a segmented PWS message in system information blocks (SIBs), each SIB carrying a segment of the PWS message, and broadcasting the SIBs.

Abstract: A simulated Public Warning System (PWS) message is defined for efficient PWS testing. The simulated PWS message mimics a conventional PWS message, but indicates that it is not to be propagated across an air interface to UEs. However, the simulated PWS message is otherwise propagated through the network as a PWS message. This allows for testing the generation and propagation of PWS messages, without wasting valuable air interface and battery resources. In some embodiments, network nodes may initiate testing by requesting a simulated PWS message. An Access and Mobility management Function (AMF) node in a wireless communication network collects and reports network status to a PWS entity. The AMF node ascertains the functionality of network functions, nodes, and interfaces to which it is connected, independently from receiving reports of such functionality, and an indication of any detected fault or failure is sent to the PWS entity.

Abstract: A method performed by a traffic analyzing element in a communication network in which a radio device communicates over a packet switched (PS) radio access bearer (RAB) with a radio access network (RAN) using compression in uplink (UL). The method comprises measuring at least one property of radio traffic between the radio device and the RAN. The method also comprises predicting a fraction of UL data on the PS RAB which will be compressible, based on the measuring. The method also comprises outputting information about the predicted fraction to a memory size estimating element in the communication network. Related are a method performed by a memory size estimating element, as well as to a memory size estimating element and a traffic analyzing element.

Abstract: Embodiments herein relate to a method in a mobile terminal for requesting access to a wireless communication system. The mobile terminal receives broadcasted system information that indicates a first available resource of a contention based channel. The mobile terminal derives a second available resource of the contention based channel based on the first available resource of the contention based channel. The mobile terminal further transmits an access request preamble mapped to the second available resource to access the wireless communication system.

Abstract: Embodiments herein relate to a method in a mobile terminal for requesting access to a wireless communication system. The mobile terminal receives broadcasted system information directly indicating first access request preambles for a first contention based channel, and indirectly indicating second access request preambles for a second contention based channel based on the directly indicated first access request preambles. The mobile terminal further derives the second access request preambles from the first access request preambles. Additionally, the mobile terminal requests access using the second access request preambles or the first access request preambles to access the wireless communication system.
