摘要:
Provided is a wireless communication system that efficiently carries out communications between a wireless control device and a wireless device. A wireless control device (20) has a wireless resource allocation unit (22) and a wireless resource instruction unit (24). The wireless resource allocation unit (22) allocates wireless resources that are used by a wireless device (30) when wirelessly communicating with a wireless terminal (2). The wireless resource instruction unit (24) sends, to the wireless device (30), instructions for causing the allocated wireless resources to be used. The wireless device (30) has a wireless signal processing unit (32) and a wireless transmission unit (34). On the basis of the instructions from the wireless control device (20), the wireless signal processing unit (32) performs processing, for performing wireless communications using the allocated wireless resources, on data to be sent to the wireless terminal (2). The wireless transmission unit (34) converts signals processed by the wireless signal processing unit (32) to wireless signals, and transmits the wireless signals to the wireless terminal (2).

摘要:
The object is achieved by providing a base station apparatus for performing time and frequency scheduling in uplink packet access with: an interference amount measurement part configured to measure an uplink interference amount for each interference amount measurement unit which comprises a predetermined period and a predetermined number of frequency blocks; an interference amount determination part configured to determine whether the uplink interference amount satisfies a predetermined condition; and an overload indicator reporting part configured to report an overload indicator to a neighboring cell when the predetermined condition is satisfied.
摘要:
In a data encoding/decoding circuit, a data encoding circuir (100) includes a first clock (111), a first time setting circuit (112), a first random number generator (113), and a converter (114) for receiving transmission data and converting the transmission data into output data with frame sync signals. A data decoding circuit (200) includes a second clock (211), a second time setting circuit (212), a frame sync extracting circuit (216), a time correction circuit (213) for correcting the time of the second clock, a second random number generator (214), and an inverter (215) for inverting output data from the frame sync extracting circuit with a random number from the second random number generator and outputting the inverted data as decoded data.
