Abstract: A method for determining a search space includes determining the number of downlink control information bits of each type of control channel currently required to be monitored by a UE. A temporary search space corresponding to the each type of control channel is determined according to a mapping relationship currently used by the UE. It is determined that an actual search space corresponding to a selected type of control channel is all or a part of CCEs of a union of temporary search spaces corresponding to all or a part of control channels with the same number of the downlink control information bits when the DCI bit number of one or more other control channels is the same as the DCI bit number of the selected type of control channel.

Abstract: A method is provided to improve resource utilization efficiency of an uplink control channel carrying feedback information, including: a terminal device receives one or more downlink channels carried in one or more first time units, which belong to a time unit set; determines a second time unit for carrying feedback information corresponding to the downlink channels according to a first association relationship between the time unit set and the second time unit; and sends uplink control information including a determined first codebook in the second time unit. When a downlink channel is received in first time units that belong to a subset of the time unit set, and there is a second association relationship between the subset of the time unit set and the second time unit, the first codebook includes only feedback information corresponding to the downlink channel carried in the first time units in the subset.

Abstract: A method and an apparatus for sending hybrid automatic repeat request acknowledgement/negative acknowledgement information are disclosed, and relate to the communications field, to specify a mechanism for feeding back information indicating whether a decoding result of downlink data repeatedly transmitted in a slot is correct. The method includes: determining a first downlink data occasion set based on a time domain resource indicated by a time domain resource allocation (TDRA) table; determining a first downlink data occasion based on a start time domain resource for sending downlink data; adding feedback information (for example, information indicating whether a decoding result of the downlink data is correct) to a feedback location corresponding to the first downlink data occasion; determining a feedback slot based on a slot to which the start time domain resource for sending the downlink data belongs and a first offset K1; and feeding back a HARQ-ACK codebook in the feedback slot.

Abstract: This application discloses a communication method, apparatus, and system. A network device sends a first downlink common signal (for example, an SSB) to a terminal device. The terminal device receives system information from the network device based on the SSB. The system information carries information indicating a first frequency domain resource and a second frequency domain resource. The first frequency domain resource and the second frequency domain resource may be two carriers or two BWPs, and the two frequency domain resources correspond to different uplink-downlink configurations. The terminal device selects a first random access resource from a random access resource set based on an association relationship between an SSB and a random access resource to send a random access preamble. The random access resource set includes a random access resource on the first frequency domain resource and a random access resource on the second frequency domain resource.
