A method and a device for determining a search space and for determining candidate control channel resources are provided in present invention. The method for determining the 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; determining a temporary search space corresponding to the each type of control channel according to a mapping relationship currently used by the UE; and determining 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.

A method, a base station, a User Equipment (UE) and a system for sending and receiving Physical Downlink Control Channel (PDCCH) signaling are disclosed. The method for sending PDCCH signaling includes the following steps: the base station determines locations of a first search space and second search space; and the base station sends only PDCCH signaling exclusive of a Carrier Indication Field (CIF) to the UE in a physically overlapped region between the first search space and the second search space if the physically overlapped region exists and length of PDCCH signaling exclusive of a CIF in the first search space is equal to length of PDCCH signaling inclusive of a CIF in the second search space.

A method and apparatus for mapping and detecting control channel are provided. The method for mapping a control channel includes: for the same aggregation level, according to a signaling length of a control channel corresponding to a component carrier, determining a corresponding search space for at least two control channels that have the same signaling length, so as to enable the at least two control channels that have the same signaling length to use the same search space, and mapping the at least two control channels that have the same signaling length to the determined corresponding search space. Therefore, conflicts between the control channels are reduced, and the number of times of blind detection of the control channels is also reduced.

A control channel mapping method is provided, which includes: determining a search space corresponding to each object for a same aggregation level, where more than one object exist and are determined according to a component carrier; and mapping a control channel corresponding to the object into the determined search space. A detection method is further provided, which includes: determining an initial location of a search space corresponding to the object, where more than one search space exist for the same aggregation level, and the object is determined according to a component carrier, and determining a size of the search space corresponding to the object; and detecting a control channel in the determined search space. A User Equipment (UE) and a network equipment are also provided. Therefore, the collision of control channels is reduced, and an impact probability of control channels is reduced.

A resource allocation method, a network device and a wireless system are disclosed. The method includes: sorting Resource Blocks (RBs) used by a terminal of a first system and a terminal of a second system according to a use situation of the RBs used by the terminal of the first system and the terminal of the second system; and allocating the sorted RBs. When some RBs are available to a Long Term Evolution (LTE) terminal, coexistence of an LTE-Advanced (LTE-A) terminal and the LTE terminal is enabled, and compatibility between the LTE-A terminal and the LTE terminal is ensured.

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.
