Embodiments of the present disclosure provide a method in a base station for coordinating resources in a wireless communications system with carrier aggregation in which a first group of terminal devices is served by a primary cell and one or more secondary cells under control of the base station. The method comprises obtaining information indicating arrival of a second group of terminal devices at coverage of the base station. A speed of any terminal device of the second group is higher than a speed of any terminal device of the first group. The method also comprises releasing resources on at least one secondary cell of the one or more secondary cells and allocating the released resources to the second group of terminal devices.

Method and apparatus for coordinating resources

A method performed by a first network node operating in with a Radio Access Technology with split architecture. The first network node is a Distributed Unit. The first network node receives one or more second indications from a second network node, a Centralized Unit. The indications comprise: i) a positive or a negative acknowledgement of a configuration conflict between a first RACH configuration in a first cell being a served cell, and a second RACH configuration in a second cell, the second cell being a neighbour cell to the first cell, ii) CU RACH assistance information associated to the conflict, the information comprising the second RACH configuration, and/or iii) a first third RACH configuration for the first cell. The first network node then updates the first RACH configuration to a second third RACH configuration, based on the indications.

First network node, second network node and methods performed thereby for handling a random access channel configuration conflict

Certain embodiments disclose systems, methods, and apparatus for establishing and using multiple Stream Control Transmission Protocol (SCTP) associations. An example method includes a network node establishing a first SCTP association and a second SCTP association for an application protocol connection with a core network node. The network node moves a user equipment (UE) associated signaling stream from the first SCTP association to the second SCTP association.

Multiple SCTP associations per S1AP connection and moving S1AP signaling connection between SCTP associations

Example embodiments presented herein are directed towards a wireless terminal and base station, and corresponding methods therein, for providing a handover for a subset of bearers associated with the wireless terminal. The subset of bearers is less than a total number of bearers associated with the wireless terminal. Thus, upon the completion of the handover procedure, at least one bearer will stay connected with a source base station.

Node and method for enabling a wireless terminal to be served by multiple cells in a communications network

Systems, methods, and apparatus for operating RAN and CN nodes are disclosed. An example method of operating a RAN node includes receiving, from a CN node, a PDU for a wireless device that is in an inactive state. The RAN node pages the wireless device in response to receiving the PDU from the CN node. The RAN node sends a non-delivery message to the CN node in response to failure of the paging for the wireless device, where the non-delivery message includes an indication that the wireless device is in the inactive state. An example method of operating a CN node includes the CN node sending a PDU for a wireless device to a RAN node. The CN node then receives a non-delivery message from the RAN node, where the non-delivery message includes an indication that the wireless device is in an inactive state.

Methods providing UE state indication upon delivery failure and related networks and network nodes

A wireless device registers with a first PLMN having a first PLMN identity. A first plurality of RA procedures is performed while registered with the first PLMN. First information related to the first plurality of RA procedures is stored. The wireless device registers with a second PLMN having a second PLMN identity different than the first PLMN identity after registering with the first PLMN and after performing the first plurality of RA procedures. The first information is discarded responsive to registering with the second PLMN. A second plurality of RA procedures is performed while registered with the second PLMN. Second information related to the second plurality of RA procedures is stored. An information message is transmitted to the second PLMN. The information message includes a plurality of RACH reports corresponding to the second plurality of RA procedures based on the second information.

Methods providing information messages including RACH reports and related wireless devices

Embodiments include methods performed by an evolved Node B (eNB) configured with a Long-Term Evolution (LTE) radio access technology (RAT). Such methods include managing access to resources of the LTE RAT by a user equipment (UE) served by the eNB, based on one or more radio resource management (RRM) policies for the LTE RAT. Such methods also include sending, to a next-generation Node B (gNB) configured with a New Radio (NR) RAT, a request to establish dual connectivity with the UE as a secondary node (SN), wherein the request includes a Subscribers Profile ID for RAT/Frequency Priority (SPID) that is associated with the one or more RRM policies. Other embodiments include complementary methods performed by a gNB, as well as eNBs and gNBs configured to perform such methods.

Slicing of network resources for dual connectivity using NR

According to certain embodiments, a method for allocating TEIDs by a CU-CP of a network node includes receiving, from a CU-UP, at least one uplink TEID (UL TEID) associated with a DRB. The at least one UL TEID is sent to a distributed unit (DU). At least one downlink TEID (DL TEID) associated with the DRB is received from the DU. The at least one DL TEID associated with the DRB is then sent to the CU-UP.

Bearer setup and establishment using tunnel endpoint identifiers (TEIDs)

A user equipment starts a first timer and a second timer in response to different respective network events. The starting of the first and second timers causes the first and second timers to simultaneously elapse. In response to one of the simultaneously elapsing timers expiring, the user equipment sends a radio link failure report to a node of a wireless communication network indicating which of the simultaneously elapsing timers expired.

Mobility robustness in a cellular network

A method in a radio access network, RAN, node for paging user equipment in an area spanning across a plurality of radio access technologies, RATs, comprises determining the capabilities of a user equipment to which a paging message is intended, and transmitting the paging message to the UE via one or more RATs which the UE is determined as being capable of communicating with.

According to certain embodiments, a method is disclosed for use in a network node. The method comprises obtaining network slice availability associated with one or more neighboring network nodes. The network slice availability indicates which of a plurality of network slices is supported by each of the one or more neighboring network nodes. The method further comprises managing slice connectivity of a wireless device based on the network slice availability of the one or more neighboring network nodes.

Handling limited network slice availability

A shared Radio Network Node, RNN, and a method for managing overload in a core network. The shared RNN is configured to serve a wireless device, and the wireless device and the RNN are operating in a wireless communications network connected to the core network. The RNN receives a connection request from the wireless device, wherein the connection request comprises a mapping parameter configured to map to an MME connected to the RNN. Further, the MME is logically partitioned into several MMEs and configured to support multiple MME Codes, MMECs, each of which MMECs is pointing at a sharing operator. The mapping parameter comprises an MMEC configured to map to one MMEC supported by the MME. Further, the RNN rejects or redirects the connection request when the MMEC configured to map to one MMEC supported by the MME is associated with an overload action.

Managing overload in at least one core network

According to certain embodiments, a method by a master network node is provided for resource coordination with a secondary network node for dual connectivity. The method includes transmitting, to the secondary network node, resource coordination information for use by the secondary network node in coordinating resource utilization between the master network node and the secondary network node for a wireless device.

Management of resource allocation and notification control over RAN interfaces

Techniques and apparatus for enabling and disabling of muting patterns in Radio Access Network (RAN) nodes for the purpose of allowing better detection and use of reference symbols used for over-the-air synchronization. An example method, in a base station operating in a wireless communications network, includes determining that a first neighbor cell of a plurality of neighbor cells is interfering with or is likely to interfere with a signal, from a second neighbor cell, that is used for synchronization. The method further includes sending, towards the first neighbor cell, a request for activation of a reference signal muting pattern by the first neighbor cell, the request including information identifying the second neighbor cell or a stratum of the second neighbor cell.
