Abstract: A method and apparatus for allocating and processing sequences in a communication system is disclosed. The method includes: dividing sequences in a sequence group into multiple sub-groups, each sub-group corresponding to its own mode of occupying time frequency resources; selecting sequences from a candidate sequence collection corresponding to each sub-group to form the sequences in the sub-group by: the sequences in a sub-group i in a sequence group k being composed of n sequences in the candidate sequence collection, the n sequences making a |ri/Ni−ck/Np1| or |(ri/Ni−ck/Np1) modu mk,i| function value the smallest, second smallest, till the nth smallest respectively; allocating the sequence group to cells, users or channels. It prevents the sequences highly correlated with the sequences of a specific length from appearing in other sequence groups, thus reducing interference, avoiding the trouble of storing the lists of massive sequence groups.

Abstract: A method for determining a search space includes determining the number of downlink control information bits of each type of control channel currently required to be monitored by a UE. A temporary search space corresponding to the each type of control channel is determined according to a mapping relationship currently used by the UE. It is determined that an actual search space corresponding to a selected type of control channel is all or a part of CCEs of a union of temporary search spaces corresponding to all or a part of control channels with the same number of the downlink control information bits when the DCI bit number of one or more other control channels is the same as the DCI bit number of the selected type of control channel.

Abstract: This disclosure discloses signal configuration methods and apparatuses. In an implementation, a method comprises: generating at least two reference signals of a same type corresponding to at least two antenna ports indicated to a terminal device, wherein the at least two reference signals comprise a first reference signal and a second reference signal, wherein a first sequence of the first reference signal is obtained based on a first initialization factor determined based on an index of a first code division multiplexing (CDM) group, and wherein a second sequence of the second reference signal different from the first sequence is obtained based on a second initialization factor determined based on an index of a second CDM group; and transmitting the at least two reference signals.

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 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.
