Claim of US Patent No. 11,071,088


1. A first user device apparatus comprising:at least one processor; and
at least one non-transitory memory including computer program code, the at least one memory and the computer program code configured, with the at least one processor, to cause the first user device to perform the following:
receive, within a wireless network, an indication that slice-specific grouped paging is supported for at least a first slice-specific paging group, wherein the first user device is a member of the first slice-specific paging group;
decode received downlink control information directed to the first slice-specific paging group to obtain scheduling information for a paging message for the first slice-specific paging group;
derive a first slice-specific paging group identifier associated with the first slice-specific paging group from a subset of bits of a first slice identifier associated with a service;
determine a paging format for which data is transmitted during the decoding of the downlink control information using the derived first slice-specific paging group identifier, wherein the received downlink control information indicates the paging format of the paging message;
receive from a base station based on the scheduling information, the paging message for the first slice-specific paging group, wherein the paging message for the first slice-specific paging group is addressed using the first slice-specific paging group identifier;
determine a data processing procedure to receive the data based on the determined paging format, the data processing procedure comprising at least one of:identifying a device identifier within a paging record included within the paging message, and initiating a service request procedure prior to receiving the data, the service request procedure comprising performing random access with the base station, the data being distinct for the first user device; or
receiving the data directly within the paging message as a data payload within the paging message; and

receive the data based on the paging message and based on the data processing procedure.
