摘要： A method for a user equipment maintaining a first set of configuration parameters includes: measuring strength of signals transmitted by a first base station, measuring strength of signal transmitted by at least one of a set of neighbor base stations operating in unlicensed spectrum, determining a second set of configuration parameters corresponding to the cellular network for a second base station in a set of neighbor base stations, by retrieving said set of configuration parameter from said second base station, considering the second base station for cell re-selection when: the measured signal strength for the second base station is higher than said measured signal strength of first base station, and said determined second set of configuration parameters corresponds to said first set of configuration parameters, and carrying out a cell selection to said second base station when these conditions are met.

摘要： Provided is a method to operate a base station that is part of a cellular network. The base station is configured to ascertain capability information from said reduced-capability user equipment indicating a capable uplink frequency bandwidth and a capable downlink frequency bandwidth. The method includes transmitting at least one first downlink signal for user equipment considering the received capability information, said first downlink signal indicating an assignment to a scheduled uplink frequency band, and scheduling information in the scheduled downlink frequency band for synchronously transmission in a predetermined nominal spacing to said scheduled uplink frequency band based on the center of the scheduled uplink frequency band and the scheduled downlink frequency band.

摘要： Provided is a method to operate a base station of a cellular network, the base station being capable of supporting bandwidth limited operation of user equipments camping on said base station, comprising the step for said base station of broadcasting a set of system information items. The set of system information items additionally comprises a first system information item indicating that camping is allowed for at least one first user equipment supporting bandwidth limited operation only. The set of system information items comprise a second system information item indicating whether newly camping is allowed for at least one second user equipments supporting additionally other modes of operation than bandwidth-limited operation, under the condition that said second user equipment is intending to use at least one of the features specific to a base station supporting bandwidth-limited operation. Other embodiments disclosed.

摘要： Provided is a method for data transmission from a user equipment to a remote server by means of a base station of a cellular network, wherein the user equipment is configured to carry out payload data transmission to said remote server. It comprises: carrying out a first signaling data transmission to the base station, determining a first power value representative of the power spent for said first signaling data transmission, maintaining the first power value as reference value, carrying out a second signaling data transmission to the base station, and determining a second power value representative of the power spent for said second signaling data transmission. In case said second power value exceeds said first power value by a predetermined threshold value, it delays the next payload data transmission for a predetermined time.

摘要： A method for a base node of a cellular network for signalling system information items in one or more system information blocks, wherein at least one system information block is transmitted only for a limited period of time lasting at least one broadcast modification period, hereinafter the on-demand system information provisioning period, the base node further signalling a primary block periodically. The method incudes: —signalling during a broadcast modification period in the primary block one first information element indicating whether in one system information item of one signaled system information block a content change appeared in comparison with the signaled system information blocks signaled prior to the broadcast modification period, and —signalling during the on-demand system information provisioning period in the primary block one second information element indicating a change in system information block scheduling compared to the scheduled system information prior to the provisioning period.
