Signalling redundancy in a wireless communication system

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.

Network architecture, methods, and devices for a wireless communications network

A method performed by a first network node for handling a connection between a wireless device and a wireless communications network. The wireless communications network comprises the first network node. The first network node stores () data related to the connection, and further stores an identifier of the wireless device for locating the stored data related to the connection later. The first network node further provides () the wireless device with a command to transition from a connected mode into a suspended mode, in which suspended mode the connection is suspended and the wireless device stores the data related to the connection, and further stores the identifier of the wireless device for locating the stored data later in order to resume the connection.

Automatic central unit user plane creation

A method by a UE is provided to handle communication in a network, wherein the UE is capable of receiving a registration area configuration including area identifiers associated with different cells of different RATs. The UE receives, from a network node, a first mobile identifier and a second mobile identifier in a message during a transition of states of the UE, wherein the first mobile identifier is of a first length and the second mobile identifier is of a second length different than the first length. Furthermore, the UE uses the first mobile identifier to resume to a first network node of a first RAT in the registration area configuration of the UE, and the second mobile identifier to resume to a second network node of a second RAT in the registration area configuration of the UE.
