  • Patent number: 9992720
    Abstract: A method in a base station (110) for enabling the base station (110) to identify a neighboring base station (120) is provided. A request is being sent (303) to a user equipment (130), commanding it to send an identification requesting message to the neighboring base station (120). In response to reception of the sent identification requesting message, a neighboring base station identifier that is associated with and identifies the neighboring base station (120), is received (303). Thereby the base station (110) is enabled to identify the neighboring base station (120). By receipt of the neighboring base station identifier, the base station becomes aware of and is enabled to contact, or connect with, the neighboring base station more directly, without the need of doing it through the user equipment. This can be done at some later point in time, for example in order to request the neighboring base station to perform handover measurements with regard to the same or another user equipment.

  • Publication number: 20180152874
    Abstract: One aspect of the teachings herein involves the temporary transfer of radio identities from one service area of a wireless communication network to another service area, where the individual radio identities are used to differentiate individual radio connections between the network and respective wireless nodes supported by the network. In particular, the temporary transfer of a given radio identity from its default service area for use in another service is limited temporally and/or geographically. Limiting the temporal and/or geographic scope of the radio identity transfer allows the network to substantially maintain default associations of radio identities and their respective service areas, which allows the network to prevent or reduce the use of conflicting radio identities in the same service area. Transfer signaling may be used transfer radio identities, and such signaling may include the temporal and/or geographic restrictions, to control the migration spread of borrowed identities in the network.

  • Publication number: 20180115989
    Abstract: Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

  • Patent number: 9917616
    Abstract: Systems and methods related to a synchronization signal particularly well suited for wireless devices in an extended coverage area of a cell of a cellular communications network are disclosed. In one embodiment, a base station transmits a synchronization signal including multiple repetitions of a basic synchronization block during a coherence time of a downlink channel over which the synchronization signal is transmitted. The multiple repetitions of the basic synchronization block during the coherence time enable coherent combining during detection of the synchronization signal at wireless devices located in the cellular communications network. This coherent combining enables, for example, wireless devices located in an extended coverage area of a cell served by the base station to synchronize to the cell using a shorter synchronization signal than that which would be required if only non-coherent combining were used.
