Abstract: A method and an apparatus is provided for sending and receiving uplink control information, including: receiving, by a terminal, a first PDCCH and a second PDCCH that are sent by a network device, where the first PDCCH and the second PDCCH are transmitted in a same time unit, the first PDCCH indicates a first PUCCH resource and is used to schedule a first downlink TB, and the second PDCCH indicates a second PUCCH resource and is used to schedule a second downlink TB; and sending, by the terminal on the first PUCCH resource, response information of the first downlink TB and response information of the second downlink TB to the network device. When one PUCCH fails to be received, the network device may obtain the response information of the two downlink TBs from the other PUCCH, thereby ensuring that HARQ feedback information of the downlink TBs is correctly received.

Abstract: Embodiments of this application provide an information transmission method and apparatus. The method includes: sending system information, wherein the system information comprises first configuration information, wherein the first configuration information is used to indicate at least one of followings: both a fixed-downlink time-frequency resource and a fixed-uplink time-frequency resource, or, that the first configuration information is used to indicate that a type of each unit time-frequency resource is not limited. This approach leads to a relatively low access delay of the user equipment, implements rapid configuration of a time-frequency resource transmission type, and improves quality of service.

Abstract: Various embodiments provide a method for receiving reference signal and a method for sending a reference signal. In those embodiments, a terminal device can determine a location of a resource element to which a reference signal is mapped. The terminal device can determine a reference signal sequence corresponding to the resource element. The index of each element in the reference signal sequence is determined based on a resource block index of a resource block corresponding to the resource element, a quantity of resource elements that carry the reference signal in the resource block, a resource block offset, or an inter-symbol offset. The terminal device can receive the reference signal by using the resource element, and performing channel estimation or channel sounding based on the received reference signal and the reference signal sequence. Therefore, the terminal device can complete channel estimation without learning of a system bandwidth.

Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting a downlink control channel. The downlink control channel includes a first downlink control channel and a second downlink control channel. The first downlink control channel includes a first RS and first DCI. A method for receiving a downlink control channel by user equipment includes: obtaining a first RS time-frequency resource corresponding to the first RS; determining a first DCI time-frequency resource corresponding to the first DCI based on the first RS time-frequency resource; detecting the first RS on the first RS time-frequency resource, and demodulating the first DCI on the first DCI time-frequency resource by using the first RS; and determining a second time-frequency resource corresponding to the second downlink control channel based on the first DCI.

Abstract: In a physical broadcast channel sending/receiving method, after receiving two broadcast channel signals on two corresponding physical broadcast channels at two time-frequency resource locations, the terminal device determines that information other than an offset of a corresponding time-frequency resource location is the same in two pieces of broadcast information carried in the two broadcast channel signals, obtains a time offset difference between the foregoing two time-frequency resource locations, and generates a scrambling code sequence based on the time offset difference; and the terminal device separately descrambles the two broadcast channel signals based on the scrambling code sequence and a preset scrambling code sequence.

Abstract: Embodiments provide a channel sounding information feedback method, user equipment, and a base station. The method includes: determining, by UE, a first period used to periodically report channel sounding information; and periodically sending, by the UE based on received preset downlink control information DCI that is sent by a base station, the channel sounding information by using the first period as a sending period. System overheads can be reduced, a configuration response can be improved, and spectrum utilization of a system can be improved while periodic feedback of indication is reduced.
