摘要： An uplink channel sending method includes sending, by a terminal device, a first uplink channel to a network device at a first power in a first time unit of a first Bandwidth Part (BWP) region, and sending, by the terminal device, the first uplink channel to the network device at a second power in a second time unit of a second BWP region. The second time unit is adjacent to the first time unit, the second BWP region is different from the first BWP region, and the second power is determined using a reset accumulated closed-loop power, an absolute closed-loop power, or the first power and an offset value.

摘要： Example methods and apparatus for sending an uplink control channel and receiving an uplink control channel are described. One example method for sending an uplink control channel includes determining a resource set to be used for an uplink control channel by a terminal device, where the uplink control channel carries uplink control information and a demodulation reference signal (DMRS). The resource set includes N resource subsets, each of the N resource subsets includes a plurality of consecutive symbols in time domain, and N is greater than or equal to 1. The terminal device determines, for each of the N resource subsets, a quantity of symbols used to carry the DMRS, where the quantity of symbols is one of at least two candidate symbol quantities. The terminal device sends the uplink control channel by using the resource set.

摘要： A slot type indication method and an apparatus and a slot type determining method and an apparatus are provided. Under the slot type indication method, a first indication information can be generated by a network device. The first indication information indicates a slot type of a first slot. When the slot type of the first slot is a predefined type, the first indication information further indicates whether a second slot is an uplink-only slot, and the first slot is a slot that includes a downlink control channel. The first indication information can be sent, by the network device, by using the downlink control channel of the first slot.

摘要： The present invention provides an information transmission method and an apparatus, so as to resolve a problem of high power consumption of a base station resulted from excessively high information overheads for transmitting an MIB by the base station. The method includes: generating, by a base station, an MIB including first bandwidth indication information and a radio frame configuration field; and sending the MIB using a time-frequency resource in a radio frame. Compared with a conventional MIB including a plurality of configuration parameters such as system bandwidth information, a frame number of a radio frame for transmitting the MIB, and PHICH configuration information, the MIB transmitted by the base station in embodiments of the present invention includes two configuration parameters: the first bandwidth indication information and the radio frame configuration field.

摘要： A data transceiving method includes: receiving a first reference signal transmitted on a subcarrier in a target physical resource block, and performing, according to a first mapping rule, corresponding processing on the first reference signal received from the subcarrier in the target physical resource block, where the first mapping rule defines at least mapping of the first reference signal to 10 specified subcarriers in a physical resource block, none of the 10 specified subcarriers are in a DC subcarrier candidate set, and the first reference signal includes a PCRS. In the embodiments of this application, only the 10 specified subcarriers in the physical resource block that are not used as DC subcarriers are selected to transmit the first reference signal, and no additional DC subcarrier is set. In this way, a quantity of downlink subcarriers in a system does not change dynamically.

摘要： A sequence-based signal processing method and apparatus are provided. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined, where the sequence is a sequence {fn} consisting of N elements, fn is an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition; then, the N elements in the sequence {fn} are respectively mapped to N subcarriers to generate a first signal; and the first signal is sent. By using the determined sequence, when a signal is sent by using a PUCCH, a low sequence correlation can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and cubic metric (CM) value can also be maintained, thereby meeting a requirement of a communication application environment in which a signal is sent by using a PUCCH.
