摘要： This application provides a downlink control information transmission method and a related apparatus. In the method, a terminal device receives first configuration information (S102). The first configuration information may indicate the terminal device to monitor a physical downlink control channel PDCCH candidate in a first scheduling cell and a second scheduling cell, and the PDCCH candidate is used to carry downlink control information for scheduling data transmission in a same scheduled cell. Further, the terminal device determines, for the same scheduled cell, monitoring upper limits of the PDCCH candidate in a first unit time and a second unit time (S103). The first unit time is determined based on a subcarrier spacing of an active downlink bandwidth part in the first scheduling cell, and the second unit time is determined based on a subcarrier spacing of an active downlink bandwidth part in the second scheduling cell. It can be learned that monitoring upper limits corresponding to two subcarrier spacings are considered in this application, and this resolves a problem of how to determine a monitoring upper limit in a scenario in which two cells schedule a same cell.

摘要： Embodiments of this application provide a paging method and an apparatus, to reduce paging overheads, and relate to the field of wireless communication technologies. In the method, a serving network device may receive positioning area information. A positioning area represented by the positioning area information herein is used by a terminal device to send an SRS in an inactive mode or an idle mode. The serving network device may send a paging message to one or more neighboring network devices in a paging area. The paging area may be determined based on the positioning area. Based on the solution, a serving base station may determine the paging area based on the positioning area, and the paging area may be a large range in the positioning area, to implement an optimal paging area configuration method, so that some unnecessary network devices can be reduced from participating in paging, to reduce resource overheads of the network device.

摘要： A method for determining feedback information, a terminal device, and a network device are disclosed. The method includes: obtaining, by a receive end device, time unit aggregation information and DAI indication information that are sent by a transmit end device; determining feedback information for at least one transport block based on the time unit aggregation information and the DAI indication information; and finally sending the feedback information for the at least one transport block to the transmit end device. This can improve a manner of determining HARQ feedback information in an NR system, so as to support a scenario with a flexible quantity of aggregated/scheduled time units, thereby avoiding understanding inconsistency and disorder of the HARQ feedback information between a terminal device and a base station on a premise of ensuring downlink control overheads and uplink feedback overheads.

摘要： This application provides a time domain resource configuration method, an apparatus, and a system. The method includes: sending, by a network device, time domain resource allocation indication information to a terminal device. The time domain resource allocation indication information is used to indicate N 1 time domain resource allocations, where N 1 is an integer greater than or equal to 1. The N 1 time domain resource allocations may be used to determine N 2 candidate time domain resources, where N 2 is an integer greater than N 1 . According to the method, more candidate time domain resources may be configured with relatively low signaling overheads.
