    Abstract: A method and system for mobility latency reduction in a hierarchical NR architecture is provided. In an embodiment, a method in a network component for handover of a UE includes configuring, by the network component, at least one TRP determined according to UE mobility information. The configuring the at least one target TRP is performed prior to the UE moving into a border area between the at least one target TRP and a first serving TRP. Configuring the at least one target TRP results in the at least one target TRP being configured to act as a secondary serving TRP to the UE. The method also includes configuring at least one target TRP and the UE with corresponding dedicated access resource and monitoring opportunities. The method also includes activating a connection and data communication between the UE and the at least one pre-configured secondary serving TRP.

    Abstract: Embodiments of the present disclosure relate to a communication method, user equipment, and a base station. The method includes: selecting, by user equipment, a DMRS from a demodulation reference signal DMRS list; sending, by the user equipment to a base station through a first channel, first data that carries the DMRS; receiving, by the user equipment through a second channel, second data that is sent by the base station and that carries feedback information, where a resource on which the second channel is located is determined based on the DMRS and a resource on which the first channel is located, or receiving, by the user equipment through a second channel, second data that is sent by the base station and that carries information about a resource on which a third channel is located, where a resource on which the second channel is located is determined based on the DMRS and a resource on which the first channel is located, and receiving, by the user equipment through the third channel, third data that is sent by the base station and that carries feedback information; and determining, by the user equipment, that the feedback information is information fed back by the base station for the first data. In the embodiments of the present disclosure, feedback information of a plurality of user equipments can be distinguished from each other while resource utilization is ensured.

    Abstract: A method, an apparatus and a network device for user data transmission are provided, where the method includes: transmitting a multicast frame for acquiring a user scheduling request to users in a user group, the multicast frame includes a long training sequence and a spread spectrum sequence(s) allocated to all users in the user group; receiving the user scheduling request(s) fed back by a user(s) with data transmission in the user group, the user scheduling request(s) is fed back by the user(s) using at least one of the long training sequence(s) and the spread spectrum sequence(s) allocated to the user(s); scheduling user data transmission according to the user scheduling request(s). According to embodiments of the present disclosure, the delay of users with data transmission is reduced, and the quality of service for the system is improved.

    Abstract: A method includes: broadcasting, by a network device, a minimum system information (MSI) message, where identification information of each SIB/system information block group in the MSI message includes an identifier of the SIB/system information block group and a type indication of the identifier, and the type indication of the identifier is used to indicate that a type of the identifier of the SIB/system information block group is an area specific system information identifier or a cell specific system information identifier. A corresponding terminal device and network device are also disclosed.

    Abstract: Embodiments provide a data sending method and device. The data sending method includes: determining, by a transmitting device, a busy/idle state of a wireless communications channel and a communication status of a receiving device before sending data to the receiving device, where the transmitting device is a wireless access node or the transmitting device is a station, and the receiving device is a wireless access node or the receiving device is a station. The method also includes sending, by the transmitting device, the data to the receiving device if the wireless communications channel is in a busy state and the receiving device is in an idle communication state.
