摘要： The embodiments of the present application provide a synchronization signal block information processing method and device, and a communication device. The method includes determining, by a terminal device, whether a first SSB and a second SSB are QCL or not according to identifiers of the first and second SSBs, and first indication information, where the identifier indicates a transmission position of the SSB within a set period of time. This method cannot only ensure that the terminal device accurately obtains the QCL relationship between the SSBs, but also can effectively use the channel resources between a start position of channel occupation and a start position of SSB transmission, and ensure the utilization efficiency of system resources in the unlicensed spectrum.

摘要： A method and device for determining time-domain resources, a storage medium, and a system. The method comprises: receiving allocation information of time-domain resources to be scheduled, which is sent by a network device (S401), the time-domain resources to be scheduled comprising time-domain resources for performing channel transmission; determining time-domain positions corresponding to the time-domain resources to be scheduled according to a set determining rule and uplink and downlink time-domain resource configuration information and the allocation information (S402); and performing, by means of the time-domain resources to be scheduled, channel transmission according to the time-domain positions corresponding to the time-domain resources to be scheduled (S403). The condition of failure to transmit a channel by a terminal in a short time period due to a conflict with time-domain configuration information when the terminal performs channel transmission is avoided, signaling overheads when the terminal performs channel transmission with the base station are reduced, and the increase of the probability of erroneous detection caused by repeated transmission of control signaling is also avoided.
