Abstract: This disclosure presents processes for improving the quality of NR PDCCH reception at a UE when transmitted in a same orthogonal frequency-division multiplexing (OFDM) symbol and a same frequency domain resource element as an LTE CRS. Using a capability parameter of the UE, a network node can transmit an LTE CRS and NR PDCCH in the same OFDM symbol and the same frequency domain resource elements using various encoding schemes. The encoding schemes can be one or more of puncture signalling, superposition signalling, relative power levels, UE type, adjusting the AL of the LTE CRS, or various combinations thereof. The UE can decode the PDDCH using the encoding scheme. Legacy UEs can be supported with this disclosure by the network node selecting supported UE capabilities for the encoding. The network node can balance transmission reliability with available resources.

One method may include providing, to at least one user equipment registered to a network within a registration area, information comprising one or more lists of single network slice selection assistance information (S-NSSAIs) and one or more lists of tracking area identities (TAIs). The one or more single network slice selection assistance information (S-NSSAIs) is included in a list of rejected single network slice selection assistance information (S-NSSAIs) or in a list of extended rejected single network slice selection assistance information (S-NSSAIs), and is associated with a cause value indicating that the one or more single network slice selection assistance information (S-NSSAIs) is not supported uniformly in the registration area and is not supported in a current tracking area.

Abstract: Systems, methods, apparatuses, and computer program products for simultaneous registration to multiple networks are provided. A user equipment (UE) may perform dual registration to multiple networks, e.g., a 5G system (5GS) of equivalent public land mobile networks (PLMNs), equivalent stand-alone non-public networks (SNPNs), or a combination of PLMNs and SNPNs. When a UE is registered to the first network, the UE may select the second network for a second registration based on one or more criteria.
