    摘要: The embodiments of the present disclosure provide a method and apparatus for transmitting and receiving a signal using an unlicensed carrier, applied in a base station. After a right to use the unlicensed carrier is preempted by the base station, the signal in remaining resources and/or a subframe subsequent is transmitted to the remaining resources, herein the signal includes one or more of start symbol identity information, a synchronization signal, a reference signal, and a service data signal, herein, the remaining resources includes the complete Orthogonal Frequency-Division Multiplexing (OFDM) symbols located in a contention back-off window and after a time point when the right to use the unlicensed carrier is contended, or complete OFDM symbols from the time point when the right to use the unlicensed carrier is contended by the base station up to an end time of a subframe in which the time point is located.

    摘要: A method and apparatus for sending information are provided, herein the method for sending information includes: the sending end using a physical control channel (PDCCH) or an enhanced physical control channel (ePDCCH) or downlink control information (DCI) transmitted in the agreed resources to describe the information about time that the unlicensed carriers are occupied; the sending end sending the DCI information through licensed carriers or the unlicensed carriers; herein, the information about time includes: a starting subframe occupying an unlicensed carrier and the number of subframes that are continuously occupied starting from the starting subframe. Through the present disclosure, how to enable base stations to mutually inform about an occupation situation of the unlicensed carrier in the related art is achieved, the coordination and utilization of the unlicensed carriers in a wireless communication system are simplified the utilization rate of the unlicensed carriers is improved.

    摘要: Methods, systems, and devices related to mobility management (e.g., reducing transmission delay and interference, and/or increasing transmission reliability) using the unlicensed spectrum are described. In one representative aspect, a method for wireless communication includes receiving, at a wireless communication node, a first message from a mobile device requesting a reestablishment of a network connection; transmitting, from the wireless communication node, a second message to the mobile device, the second message including information for reestablishing and reconfiguring the network connection; and receiving, at the wireless communication node, a third message from the mobile device acknowledging at least one of (1) completing a reestablishment of the network connection, or (2) completing a reconfiguration of the network connection.
