摘要： A cell within cellular network includes user equipment (UE) that transmits data to a base station (eNB). When a UE does not have data to transmit, it may enter a low power mode (DRX) having silent intervals during which the eNB does not expect to receive a transmission from the UE and the UE is not required to monitor DL control channels from the eNB. While in DRX mode, the UE may detect an event, such as data ready for transmission or a need to request a timing adjustment (TA) update. The UE transmits a scheduling request indicator (SRI) to the eNB in response to detection of the event, wherein the SRI carries information identifying the triggering event.

摘要： This invention extends the coverage and improves the capacity of wireless communication networks using relay nodes. The relay nodes are wirelessly connected to the base station. The base station uses the same radio access technology for a link between the base station and user equipment and between the base station and the relay node.

摘要： A transmission within a wireless cellular network may include a first and second type of information. A subframe includes a plurality of symbols, at least one symbol is designated as a data symbol and at least one symbol is designated as a reference signal symbol that contains a pre-defined reference signal. The first type of information is embedded in the data symbols. If the second type of data is expected, then the second type of information is embedded in at least one reference symbol by quadrature amplitude modulating the pre-defined reference signal. The subframe is then transmitted from one node in the network to a second node. If it is determined that the second node is not expecting the second type of information, then a discontinuous transmission (DTX) response is embedded in the reference symbol instead of the second type of information.
