Abstract: In a communication method disclosed in this application, a terminal device receives, from a network device, a synchronization signal and a system information signal that are generated based on a first subcarrier spacing. The terminal device sends a random access request signal to the network device based on a second subcarrier spacing and a first transmission resource, where a type of the first transmission resource corresponds to a third subcarrier spacing and/or a fourth subcarrier spacing. The terminal device further receives a random access response signal generated based on the fourth subcarrier spacing, where the random access response signal is used for instructing the terminal device to access a network or the random access response signal is used for instructing the terminal device to prepare to access network. Thereby, cell search for and random access to a network using a plurality of subcarrier spacings can be supported.

Abstract: Embodiments of this application provide a control information sending method and apparatus. A network device generates first control information for a first TB, where the first TB includes n code block (CB) groups, where N is a maximum quantity of CB groups included in the first TB; each CB group includes at least one CB; the first control information includes N control information fields, and the N control information fields are in correspondence with the maximum N CB groups included in the first TB; and a control information field i in the N control information fields is used to indicate whether a CB group corresponding to the control information field i is to be sent or received, and i∈[1, N]. In this way, a quantity of bits included in downlink control information can remain fixed, thereby reducing blind detection complexity of a terminal device.

Abstract: In a data sending method, a terminal device receives first control information in a first time unit. The first control information indicates a first time domain resource that is used to send a first information block. The terminal device receives the first information block on at least a part of the first time domain resource based on the first control information. The terminal device further receives second control information in a second time unit. The second control information indicates a second time domain resource that is used to send the first information block. The terminal device receives the first information block on the second time domain resource based on the second control information. The first time unit is different from the second time unit, and the first time domain resource and the second time domain resource have an overlapping time domain resource.

Abstract: A method is provided, including: determining, a first receiving state corresponding to a first data channel and a second receiving state corresponding to a second data channel; generating, a hybrid automatic repeat request-acknowledgement HARQ-ACK feedback message, where the HARQ-ACK feedback message is at least used to indicate the first receiving state and the second receiving state, a first time length of a time domain resource occupied by the first data channel is less than a second time length of a time domain resource occupied by the second data channel; and sending, the HARQ-ACK feedback message on a time domain resource having a third time length. By using the foregoing solution, the terminal device can efficiently feed back, receiving states corresponding to a plurality of data channels or a plurality of pieces of data transmission that occupy time domain resources of different lengths, thereby ensuring communication service quality.

Abstract: Devices and methods are provided for receiving a first indication and a second indication, the first indication associated with a first set of transmission parameter information for a first repetition of data received in a Physical Downlink Shared Channel (PDSCH) and the second indication associated with a second set of transmission parameter information for a second repetition of data received in the PDSCH. Each set of transmission parameter information corresponds to a Quasi-Co-Location (QCL) information for the respective repetition of data. In addition, the method involves receiving a first PDSCH repetition and a second PDSCH repetition. A channel estimate can then be performed for the first PDSCH repetition based on the QCL information for the first PDSCH repetition and a channel estimate for the second PDSCH repetition based on the QCL information for the second PDSCH repetition.
