1. A method in a network node of a wireless communications network, the method comprising:
- initiating broadcast, from a base station of the wireless communications network, of a first system information signal containing a first system information part for the wireless communication network;
obtaining one or more radio properties of one or more signals received from one or more mobile devices; and
using the one or more radio properties to formulate a second system information signal containing a second system information part; and
,in response to receipt by the base station of one or more request signals from the one or more mobile devices, initiating transmission, from the base station, of the second system information signal.

Abstract
The present disclosure provides methods and apparatus for a wireless communications network in which system information can be provided on an efficient basis to mobile devices in the network. The system information is split into two parts, with the second part being transmitted to mobile devices in response to receipt of one or more request signals from those mobile devices. The second system information part may additionally be broadcast.

14. A network node for a wireless communications network, the network node comprising processor circuitry and a computer-readable storage medium, the computer-readable storage medium storing instructions that are executable by the processor circuitry whereby the network node is operative to:
-
initiate broadcast, from a base station of the wireless communications network, of a first system information signal containing a first system information part for the wireless communication network; obtain one or more radio properties of one or more signals received from one or more mobile devices; and use the one or more radio properties to formulate a second system information signal containing a second system information part; and in response to receipt by the base station of one or more request signals from one or more mobile devices, initiate transmission, from the base station, of the second system information signal.

15. A method in a mobile device of a wireless communications network, the method comprising:
-
receiving, from a base station of the wireless communications network, a first system information signal containing a first system information part for the wireless communication network; determining the received power of the first system information signal; comparing the received power to one or more threshold values; and determining which set of transmission parameters, of a plurality of sets of transmission parameters, to use for a request signal based on the comparison; transmitting to the base station the request signal requesting transmission of a second system information signal containing a second system information part, wherein the step of transmitting the request signal comprises transmitting the request signal using the determined set of transmission parameters; and receiving, from the base station, the second system information signal containing the second system information part. - View Dependent Claims (16, 17)

18. A mobile device comprising at least one antenna, processor circuitry and a computer-readable storage medium, the computer-readable storage medium storing instructions that are executable by the processor circuitry whereby the mobile device is operative to:
-
receive, from a base station of a wireless communications network, a first system information signal containing a first system information part for the wireless communication network; determine the received power of the first system information signal; compare the received power to one or more threshold values; and determine which set of transmission parameters, of a plurality of sets of transmission parameters, to use for a request signal based on the comparison; transmit to the base station the request signal requesting transmission of a second system information signal containing a second system information part, using the determined set of transmission parameters; and receive, from the base station, the second system information signal containing the second system information part.
