摘要： A wireless communication system includes an apparatus capable of detecting whether a cell coverage is downscaled. The wireless communication system receives information used for communication between an evolved NodeB (eNodeB) and a User Equipment (UE) from the eNodeB. The UE performs at least one of pilot signal power checking for checking if a pilot signal power falls within a first reference range, DownLink (DL) Signal-to-Interference plus Noise Ratio (SINR) checking for checking if an SINR of a DL traffic channel falls within a second reference range, and UpLink (UL) SINR checking for checking if an SINR of an UL traffic channel falls within a third reference range using the received information. The UE also detects whether a cell coverage of a cell to which the eNodeB and the UE belongs is downscaled based on a checking result.

摘要： An uplink packet data transmission system and method are provided which can reduce a collision probability in a contention period by assigning a priority to mobile stations when bandwidth allocation is rejected due to lack of resources of a base station from which a best effort service is provided. In a method for transmitting best effort data in a communication system, the base station allocates resources to mobile stations for which a reservation has been made in a previous time period when bandwidth for the mobile stations requesting bandwidth allocation is insufficient, reserves bandwidth for mobile stations for which the bandwidth allocation has been rejected, and transmits reservation information. The mobile stations receive the reservation information, skip a next scheduled bandwidth allocation request, and transmit data through bandwidth allocated from the base station.
