Abstract: A HARQ-ACK transmission method and an apparatus. A network device configures at least two common PUCCH resource sets for a terminal device, and sends, to the terminal device, configuration information indicating the at least two common PUCCH resource sets. After receiving the configuration information from the network device, the terminal device determines, from the at least two common PUCCH resource sets, a first PUCCH resource used to send HARQ-ACK information, and sends the HARQ-ACK information to the network device based on the first PUCCH resource. Available PUCCH frequency domain resources are able to be added for the terminal device in a same slot. PUCCH frequency domain resource collision is reduced, and a transmission delay that is increased to avoid the PUCCH frequency domain resource collision is reduced.

Abstract: This application provides an uplink transmission resource determining method and an apparatus. The method includes: receiving first system information sent by a network device, where the first system information includes a first PUSCH resource configuration; determining whether a preset condition is met; receiving second system information sent by the network device when the preset condition is not met, where the second system information includes a second PUSCH resource configuration; and determining, based on the second PUSCH resource configuration, a parameter used for uplink transmission. In this way, a terminal may flexibly select the PUSCH resource configuration in the first system information or the PUSCH resource configuration in the second system information based on a requirement of the terminal. The second system information is received only when the preset condition is not met, to reduce information obtained by the terminal and reduce power consumption of the terminal.

Abstract: A reference signal indication method and an apparatus are disclosed to indicate a to-be-reported reference signal in a random access process. The to-be-reported reference signal is a reference signal with a largest receive power. In the solutions disclosed in this application, the reference signal with the largest receive power may be reported. In this way, a network device can determine an optimal transmit beam, and can further determine an optimal receive beam, so that the optimal transmit beam and/or the optimal receive beam can be used to communicate with a terminal, to improve a beam gain of data transmission in the random access process.

Abstract: This application provides a random access method and an apparatus. The random access method includes: User equipment sends a random access message of a first-type random access procedure to a network device. The random access message of the first-type random access procedure includes a random access preamble and uplink data. The user equipment starts a first time window after transmission of the random access preamble ends, and detects first downlink control information DCI and second DCI within the first time window. The first DCI is used to schedule a first physical downlink shared channel PDSCH that carries a first response message for the random access preamble, and the second DCI is used to schedule a second PDSCH that carries a second response message for the random access message.

Abstract: Embodiments of this application provide a random access method, an apparatus, and a system. A terminal device receives, from a network device, information about a PRACH resource set and information about one or more PUSCH resources associated with each PRACH resource in the PRACH resource set. If a first PUSCH resource associated with a valid first PRACH resource in the PRACH resource set is valid, the terminal device sends a first preamble sequence to the network device on the first PRACH resource, and sends uplink data to the network device on the first PUSCH resource. The network device receives the first preamble sequence from the terminal device on the first PRACH resource, and receives the uplink data from the terminal device on the first PUSCH resource. The first preamble sequence is a preamble sequence in a preamble sequence set associated with the first PUSCH resource.
