    Abstract: A method and a device for detecting downlink control information. The method includes: a Relay Node (RN) receiving control information born in a Relay Physical Downlink Control Channel (R-PDCCH) sent by an evolved Node B (eNB) to acquire a control resource; the RN performing detection on the control resource according to an index of the control resource to acquire own control information; wherein the control resource is a Relay Control Channel Element (R-CCE) or a Physical Resource Block (PRB). System overhead can be saved and system transmission efficiency can be improved.

    Abstract: A method and system for transmitting a relay link control channel are disclosed for realizing the mapping and transmission of a control channel on a link from an eNode-B to a relay node. In the present invention, in a frequency division multiplex mode, control information is carried by one or more resource blocks in the frequency direction and the universal set of OFDM symbols available to a relay link in a subframe in the time direction; in a time division and frequency division multiplex mode, control information is carried by one or more resource blocks in the frequency direction and a subset of OFDM symbols available to a relay link in a subframe in the time direction; in a time division multiplex mode, control information is carried by all the resource blocks in the frequency direction and a subset of OFDM symbols available to a relay link in a subframe in the time direction; and the mapping of the control channel includes mapping in the time direction and/or the frequency direction. The present invention has backward compatibility and can obtain frequency diversity again. The time division multiplex mode can save power consumption, and the frequency division multiplex mode and the time division and frequency division multiplex mode have the advantages of flexible service scheduling.

    Abstract: A device classifies access or control channel signals into a first class or a second class, initializes a dormancy timer associated with the device, and sets the dormancy timer to a default value. The device also sets a signal target utilization threshold, receives actual signals via the access or control channel, and identifies, when a number of the actual signals exceeds the signal target utilization threshold, a particular signal, from the actual signals, as belonging to the first class or the second class. The device further increases the default value of the dormancy timer when the particular signal belongs to the first class, and decreases the default value of the dormancy timer when the particular signal belongs to the second class.
