摘要： This application discloses a communication method and a communication apparatus. In the method, a terminal device can report a first capability indication to an access network device. The first capability indication can indicate that the terminal device causes no uplink transmission interruption in a band that does not involve uplink radio frequency chain switching in an uplink radio frequency chain switching period, and the uplink radio frequency chain switching is supported between a band in which uplink switching is performed in the uplink radio frequency chain switching period and the band that does not involve the uplink radio frequency chain switching. In other words, when both a band in which uplink radio frequency chain switching is being performed and a band that does not involve the uplink radio frequency chain switching exist in several bands that support the uplink radio frequency chain switching, no uplink transmission interruption is caused in the band that does not involve the uplink radio frequency chain switching. When no uplink interruption is caused in the band that does not involve the uplink radio frequency chain switching, this helps avoid a waste of time-frequency resources.

摘要： This application provides a sequence-based signal processing method and apparatus. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined The sequence is a sequence { f n } consisting of 12 elements, f n represents an element in the sequence { f n }, and the determined sequence { f n } is a sequence meeting a preset condition. Then, the 12 elements in the sequence { f n } are respectively mapped to 12 subcarriers, to generate a first signal, and the first signal is sent. By using the determined sequence, when the signal is sent by using the PUCCH, a low correlation between sequences can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and a relatively small cubic metric (CM) value can be maintained. Therefore, a requirement of a communication application environment in which the signal is sent by using the PUCCH is met.

摘要： This application provides an uplink transmission method and a communication apparatus. In the method, a terminal device receives first indication information, and the first indication information indicates at least two uplink carriers, to effectively reduce control signaling overheads. In addition, the terminal device sends uplink transmission on the at least two uplink carriers based on the first indication information, so that the terminal device sends the uplink transmission on a plurality of uplink carriers. Therefore, in this application, the uplink transmission is sent on the plurality of uplink carriers when control signaling overheads are reduced, so that an objective of using a plurality of uplink spectrum resources to increase an uplink capacity is achieved.

摘要： A communication method and apparatus are provided. The method includes: A terminal device determines a first sequence whose length is ∑ i = 0 M − 1 K i , and sends the first sequence on M subcarrier groups, where an i th subcarrier group in the M subcarrier groups includes K i subcarriers on a same symbol, i = 0,1, ... , M - 1, and frequency domain positions of subcarriers included in any two of the M subcarrier groups are different and belong to different symbols; and a sequence carried in each of the M subcarrier groups is a fragment of the first sequence, and fragments carried in any two subcarrier groups are different. According to the method, the terminal device sends the first sequence on the M subcarrier groups, so that interference between different terminal devices is small when channel estimation is performed by combining M symbols. This can effectively improve accuracy of channel estimation.

摘要： This application provides a sequence-based signal transmission method and a communication apparatus. The method includes: determining a first sequence based on a first parameter, a second parameter, and a third parameter, where the first sequence is determined based on the third parameter and a second sequence, the second sequence is determined based on the first parameter and the second parameter, the first parameter and the second parameter are root indexes of the second sequence, and the third parameter is a time domain cyclic shift value; and sending a signal based on the first sequence. According to the method provided in this application, one root sequence (the second sequence) is determined based on the two root indexes (the first parameter and the second parameter). The first sequence is determined based on the second sequence and the time domain cyclic shift value, and the signal is determined based on the first sequence. A quantity of different root sequences may be increased, so that a probability that different terminal devices use a same sequence is reduced, and the different terminal devices are prevented from using a same signal. This reduces interference between signals sent by the different terminal devices and can ensure efficiency of signal transmission for more users.

摘要： A control information transmission method, a base station, and user equipment are disclosed. The transmission method includes: sending, by a base station, first control information on a second carrier, where the first control information is used by the base station to send data on a first carrier according to the first control information; and sending, by the base station, the data on the first carrier according to the first control information; where duration of a transmission time interval of the first carrier is less than duration of a transmission time interval of the second carrier. A base station sends data on a first carrier, and sends first control information on a second carrier. Because a frequency of the second carrier is less than a frequency of the first carrier, a large-scale loss on the second carrier is less than a large-scale loss on the first carrier. Therefore, sending the first control information on the second carrier improves reliability of transmission of the first control information.
