Abstract: Systems, methods, and software of directly connecting a SIM-less device with a cellular network. In one embodiment, User Equipment (UE) includes a Subscriber Identity Module 5 (SIM) provisioned with a plurality of subscription profiles for subscriptions to the cellular network. The UE establishes a direct communication with a SIM-less device that does not have a subscription with the cellular network. The UE selects one of the subscriptions provisioned in the SIM as a temporary subscription assigned to the SIM-less device to allow the SIM-less device to establish a direct connection with the cellular network using the 10 temporary subscription, and transmits a message to the SIM-less device via the direct communication containing subscription credentials for the temporary subscription. The SIM-less device may therefore register with the cellular network using the subscription credentials provided by the UE, and establish a direct connection with the cellular network using the temporary subscription.

Abstract: Systems, methods, apparatuses, and computer program products for indicating network node fixed frame period (FFP) or UE FFP. A UE may transmit an uplink (UL) signal at a start of a UE FFP. A network node may respond by allocating UL resource(s) for subsequent UE transmission(s). The network node may implicitly signal, in Downlink Control Information (DCI), whether a UL transmission is to be transmitted based on assuming a UE FFP or a network node FFP for the UL transmission. The UE may make this assumption based on a cyclic prefix (CP) extension indication in DCI. For example, for certain CP extensions, the UE may determine to transmit the UL transmission according to the UE FFP. Otherwise, the UE may determine to transmit the UL transmission according to a network node FFP.

Abstract: A network node allocates primary frequency resources and at least one secondary frequency resource to a user equipment (UE) within a dynamically changing bandwidth (BW) of a cell served by the network node. The network node further configures the UE to use the primary frequency resources for an UL transmission when the primary frequency resources fall within an UL part of the BW, and to use the secondary frequency resource for the UL transmission when the primary frequency resources fall, at least partly, within a downlink (DL) part and/or a Guard Band (GB) of the BW, and/or fall, at least partly, outside the BW. The UE may dynamically, based on such configuration from the network node, adapt its resource allocation to perform the UL transmission even if the primary frequency resources are not fully within the UL part of the BW in a current time resource.

Abstract: A node configured to support a method of communicating between two nodes in the unlicensed spectrum is disclosed where a channel can be simultaneously used for downlink and uplink communication. The method performed at a node involves assessing at that node, for example, a UE, that there is a transmission to be made to a further node, for example a gNB. The first node receives an indication that communication with the further node is supportable on a channel within an unlicensed spectrum using flexible frequency division duplex (FDD) techniques. The first node determines whether transmission by the further node is being made within a first portion of the channel within the unlicensed spectrum; and if so, transmits to the further node within a second portion of the channel which does not overlap with the first.
