    Publication number: 20230284102
    Abstract: The present disclosure generally relates to the field of Radio Resource Control (RRC). More specifically, the present disclosure relates to techniques of supporting and initiating RRC connection establishment in a wireless communication network. A method embodiment relates to supporting RRC connection establishment in a wireless communication network and comprises setting up context information during a first RRC connection establishment procedure to establish a first RRC connection towards a radio access network element (200) of the wireless communication network implementing a first Radio Access Technology (RAT). The context information is associated with a wireless communication device (100) of the wireless communication network and is usable for a second RRC connection establishment procedure to establish a second RRC connection towards a radio access network element of the wireless communication network implementing a second RAT.

    Abstract: Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

    Abstract: Embodiments include methods for a network node of a 3GPP RAN. Such methods include determining a configuration that enables a UE to steer the UE's traffic between the 3GPP RAN and a WLAN without receiving a traffic steering command from the 3GPP RAN. The configuration includes a forward traffic steering configuration comprising a first plurality of thresholds/conditions for which the UE, when connected to 3GPP RAN, can initiate steering at least some of the UE's traffic from 3GPP RAN to WLAN; and a backward traffic steering configuration comprising a second plurality of thresholds/conditions for which the UE, when connected to WLAN, can initiate steering at least some of the UE's traffic from WLAN to 3GPP RAN. The backward traffic steering configuration includes threshold(s)/condition(s) based on different values of a same parameter as threshold(s)/condition(s) of the forward traffic steering configuration. The configuration is sent to the UE in a single message.

  • Energy-saving mechanisms in a heterogeneous radio communication network
    Patent number: 11218960
    Abstract: There is provided support mechanisms for at least one adding and removing a cell from operation in a heterogeneous radio network having a first type of basic cell for providing basic radio coverage and a second type of cell associated to a basic cell as a capacity enhancing cell. A capacity enhancing cell is selectively switched on and off. When the capacity enhancing cell is shut down the cell does not exist over the air while cell configuration information is kept. When the capacity enhancing cell is switched on the cell becomes available again over the air interface. An indication of shut-down and a wake-up call message for switch-on of the capacity enhancing cell are communicated between a base station serving the capacity enhancing cell and a base station serving the basic cell. In this way energy savings can be supported without disrupting service availability.

  • Network nodes and methods performed therein for enabling communication in a communication network
    Patent number: 10966128
    Abstract: Embodiments herein relate to a method performed by a wireless device, for handling a mobility procedure in a communication network. The communication network comprises a first network and a second network. The first network is associated with a core network node and a first RAN node. The second network is associated with a second RAN node. The first RAN node and the second RAN node each support a set of cells. The first and the second network comprise partitioned sets of functionalities, wherein a first set of functionalities belongs to a first network slice supporting the wireless device. The wireless device is associated with the first network and the first network slice in a first cell of the first RAN node. The network slices and corresponding network slice identities are uncoordinated between the first and the second network. The wireless device receives, from the core network node, a message comprising an indication of combinations of networks and network slices equivalent to the first network slice.
