摘要： It provides a method (300) for polar decoding a received signal into a number, N, of bits with Successive Cancellation List, SCL. The method (300) includes: at the i-th level of a binary tree for decoding the i-th bit of the N bits, where 1≤i≤N: when the i-th bit is an information bit, calculating (310) a path metric for each of 2*Li-1 candidate paths at the i-th level, where Li-1 is an SCL size at the (i−1)-th level and L0=1; setting (320) an SCL size at the i-th level, Li, based on Li-1 and a statistical distribution of the path metrics calculated for the 2*Li-1 candidate paths; and selecting (330) Li surviving paths from the 2*Li-1 candidate paths based on their respective path metrics.

摘要： Methods and apparatuses are disclosed for facilitating roaming of terminal device. According to an embodiment, a session management node operable in a home network receives, from another session management node operable in a visiting network, a quality of service (QoS) policy per a roaming agreement between the visiting network and the home network during establishment of a protocol data unit (PDU) session for a terminal device. The session management node retrieves, from a subscriber management node, subscribed QoS parameters of the terminal device. The session management node obtains a result that is generated based on the QoS policy per the roaming agreement and the subscribed QoS parameters of the terminal device.

摘要： A Central Unit-Control Plane (CU-CP) of a radio access network (RAN) node can operate in a communication network to dynamically schedule user-plane (UP) communications. The CU-CP can be communicatively coupled to a Distributed Unit (DU) and a Central Unit-User-Plane (CU-UP) of the RAN node. The CU-CP can provide indication of one or more available UP paths to at least one network element. The at least one network element can include one or more of: a user equipment, UE; the CU-UP of the RAN node; and/or the DU of the RAN node. The CU-CP can provide indication of a scheduling strategy for data transmissions to the at least one network element.
