Abstract: This application provides a communication method, an apparatus, and a computer-readable storage medium. The communication method includes: generating at least one reference signal. The at least one reference signal belongs to a reference signal set, and all reference signals in the reference signal set occupy a same time-frequency resource. The reference signal set includes at least two groups of reference signals, and each group of reference signals satisfies: Each group includes a plurality of reference signals, and the plurality of reference signals are pairwise orthogonal. For reference signals with same frequency-domain sequences, corresponding time-domain sequences are orthogonal to each other. For reference signals with same time-domain sequences, corresponding first frequency-domain sequences are orthogonal to each other, and corresponding second frequency-domain sequences are also orthogonal to each other. Based on embodiments of this application, interference between reference signals can be reduced.

Abstract: 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. The sequence is a sequence {fn} consisting of 12 elements, fn represents an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition. Then, the 12 elements in the sequence {fn} 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.

Abstract: The present disclosure relates to signal processing methods and apparatus. One example method includes determining a first sequence {x(n)} based on a preset condition, generating a reference signal of a first signal by using the first sequence, and sending the reference signal on a first frequency-domain resource. The preset condition is y n = A · e j × π × s n 8 , x n = A · e j × π × s n 8 , a length of the first sequence is K=6, n=0, 1, . . . , K−1, A is a non-zero complex number, and j=√{square root over (−1)}. The first signal is a signal modulated by using π/2 binary phase shift keying (BPSK). The first frequency-domain resource comprises K subcarriers each having a subcarrier number of k, k=u+L*n+delta, L is an integer greater than or equal to 2, delta∈{0, 1, . . . , L−1}, u is an integer, and subcarrier numbers of the K subcarriers are numbered in ascending or descending order of frequencies.

The sequence is a sequence {x} including N elements, xn is an element in the sequence {xn}, and the determined sequence {xn} is a sequence satisfying a preset condition. Then, a first signal is generated and sent. By using the determined sequence, when a signal is sent on the PUSCH, relatively good sequence frequency domain flatness can be maintained, and a relatively low PAPR. value and a relatively low cross-correlation between sequences can be maintained, thereby satisfying a communications application environment in which a signal is sent on the PUSCH, especially an NR system scenario or an NR similar scenario.

Abstract: A sequence distributing and sequence processing method and apparatus in a communication system are provided. The sequence distributing method includes the following steps: generating sequence groups including a number of sequences, the sequences in the sequence groups are determined according to the sequence time frequency resource occupation manner which is supported by the system; distributing the sequence groups to cells. The method avoids the phenomenon that signaling transmission is needed to distribute the sequences to the cells for different time frequency resource occupation manner, and saves in so far as possible the wireless network transmission resource occupied during the process of distributing the sequences through distributing the sequence groups comprising a number of sequences to the cells.

Abstract: A resource allocation method includes: determining a resource block allocation field in downlink control information, where when a value indicated by five least significant bits of the resource block allocation field is less than or equal to 20, the five least significant bits of the resource block allocation field indicate a resource that is allocated within an indicated narrowband by using an uplink resource allocation type 0; or when a value indicated by five least significant bits of the resource block allocation field is greater than 20, the resource block allocation field indicates a quantity of resource block groups allocated to a terminal device and an index of a starting resource block group allocated to the terminal device. The method provided in this embodiment improves the coverage capability of the network. The method can be applied to the Internet of Things, such as MTC, IoT, LTE-M, M2M, etc.
