    Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting a downlink control channel. The downlink control channel includes a first downlink control channel and a second downlink control channel. The first downlink control channel includes a first RS and first DCI. A method for receiving a downlink control channel by user equipment includes: obtaining a first RS time-frequency resource corresponding to the first RS; determining a first DCI time-frequency resource corresponding to the first DCI based on the first RS time-frequency resource; detecting the first RS on the first RS time-frequency resource, and demodulating the first DCI on the first DCI time-frequency resource by using the first RS; and determining a second time-frequency resource corresponding to the second downlink control channel based on the first DCI.

    Abstract: Embodiments of the present invention provide information sending and receiving methods and devices. The information sending method includes: determining, by a base station, a downlink subframe that is used to send first information to user equipment UE; and sending, by the base station, the first information to the UE by using the downlink subframe, where the downlink subframe is a first subframe, a second subframe, or a third subframe, where the first subframe includes at least two sub-physical resource block pairs, the second subframe includes at least two physical resource block pairs, and the third subframe includes at least one sub-physical resource block pair and at least one physical resource block pair. According to the embodiments of the present invention, an LTE communications system efficiently and flexibly supports various network architectures and various types of UEs.

    Abstract: Embodiments provide a channel sounding information feedback method, user equipment, and a base station. The method includes: determining, by UE, a first period used to periodically report channel sounding information; and periodically sending, by the UE based on received preset downlink control information DCI that is sent by a base station, the channel sounding information by using the first period as a sending period. System overheads can be reduced, a configuration response can be improved, and spectrum utilization of a system can be improved while periodic feedback of indication is reduced.

    Abstract: Embodiments of the present invention provide a detecting method, a transmitting method and an apparatus for a common control channel. The detecting method includes: determining a candidate resource set within virtual downlink resources of a current cell. The candidate resource set can include at least one candidate resource carrying a common control channel of the current cell. A detection is performed on at least one candidate resource in the candidate resource set, so as to acquire the common control channel of the current cell. In the embodiments of the present invention, a selection range of resources for transmitting a common control channel is extended, so that inter-cell interference of the common control channel can be coordinated, and a detection performance of the common control channel can be improved.

    Abstract: A method and an apparatus for allocating ACKnowledgement (ACK)/Non-ACKnowledgement (NACK) channel resources and processing confirmation information are disclosed. The method includes: The network side determines one physical channel area among multiple physical channel areas to be used by an ACK/NACK channel, and notifies the determined physical channel area to a User Equipment (UE) so as to enable the UE to determine a channel for receiving or sending ACK/NACK information in the determined physical channel area according to a mapping rule. Moreover, the network side may send or receive ACK/NACK information on the physical channel area that includes the ACK/NACK channel. The method and apparatus improve the utilization ratio and flexibility of the ACK/NACK channel, and reduce the probability of conflict generated by the ACK/NACK channel.
