Abstract: An apparatus for use by a first communication network control element configured to control a communication connection of at least one communication element in a first network area providing a specific communication capability, the apparatus including processing circuitry, and memory for storing instructions to be executed by the processing circuitry, wherein the memory and the instructions are configured to, with the processing circuitry, cause the apparatus at least: to determine that a communication element communicating in the first network area and using the specific communication capability enters a second network area which does not provide the specific communication capability and that there is a switching of the communication connection to the second network area, and to cause sending of connection switching information related to the switching of the communication connection of the communication element to a second communication network control element.

Abstract: The present invention introduces a beam-based UE mobility state estimate for power saving purposes, based on monitoring the distinct beam(s) (302) detected by the UE. In other words, the number N of distinct serving beams changed by the UE within a time window T is monitored (302) against the configured threshold values. If N is below a first threshold value “Thr1”, a low/stationary mobility state is determined (303) and the UE applies a first measurement configuration (305) associated with the low/stationary mobility state. If N is between first and second threshold values “Thr1” and “Thr2”, a medium mobility state is determined (304) and the UE applies a second measurement configuration (306) associated with the medium mobility state. If N is above the second threshold value “Thr2”, a high mobility state is determined and the UE applies a third measurement configuration associated with the high mobility state.

Abstract: A method includes receiving, from a base station, network signaling including information about one or more of a timing advance scaling parameter, a processing-delay compensation parameter, and a timing advance extension parameters enabling threshold/condition; receiving a timing advance index from the base station; adjusting parameters for uplink transmissions using the received timing advance index for the one or more of the timing advance scaling parameter, the processing-delay compensation parameter, and the timing advance extension parameters enabling threshold/condition; and performing uplink transmissions according to the configured and adjusted parameters. Another method includes sending, to a user equipment, network signaling including information about one or more of a timing advance scaling parameter, a processing-delay compensation parameter, and a timing advance extension parameters enabling threshold/condition; sending a timing advance index to the user equipment; and receiving uplink transmissions according to the configured and adjusted parameters.

Abstract: A user equipment (UE) has both cellular and non-cellular links. The network sends it a first indication to maintain using a first set of security keys generated from a parameter specific to a source access node after the UE hands over the cellular link to a target access node without changing a wireless termination (WT) that is connected with the UE via the non-cellular link. The network uses that key to maintain the non-cellular link with the UE after the cellular link handover. From the UE's perspective it uses that key to authenticate its non-cellular link prior to the cellular link handover, but this handover does not change the WT which communicates with the UE via the non-cellular link so the UE can, only in response to receiving a first indication associated with the handover, use that same key to maintain that non-cellular link after the handover.

Abstract: Various communication systems may benefit from communication between two different radio access technologies. For example, a long term evolution network may benefit from receiving resource availability information from a wireless local area network. A method includes receiving a request from a first RAT at a network node in a second RAT, and at least partially rejecting or at least partially accepting the request. The method also includes sending an indication of the at least partial rejection or at least partial acceptance to the first radio access technology, where the indication is used in determining whether to activate or continue radio access aggregation.

Abstract: There are provided measures for measurement relaxation change based on the total received power, in particular on an indicator of the total received power. Such measures exemplarily comprise, at a terminal in a radio resource management measurements relaxation mode having a reduced radio resource management measurements activity within a first relaxation mode scope as a relaxation mode scope of said radio resource management measurements relaxation mode, the terminal being served by a radio cell in a frequency band, achieving information on a parameter indicative of a total power received by said terminal at said frequency band, and deciding on a change of said relaxation mode scope of said radio resource management measurements relaxation mode based on said information on said parameter indicative of said total power received by said terminal at said frequency band.
