Abstract: DISCLOSED ARE A WIRELESS COMMUNICATION APPARATUS AND FREQUENCY HOPPING METHOD WHICH MINIMIZE THE CHANGE IN THE INSTANTANEOUS POWER DISTRIBUTION CHARACTERISTICS OF THE TIME WAVEFORM OF TRANSMISSION SIGNALS WHEN A PLURALITY OF CHANNELS ARE MULTIPLEXED BY FREQUENCY DIVISION. AT A TERMINAL (200, 200A), A MAPPING UNIT (212) MAPS THE PUCCH TO FREQUENCY RESOURCES OF A FIRST SLOT, MAPS THE PUSCH TO FREQUENCY RESOURCES, AMONG THE FREQUENCY RESOURCES OF THE FIRST SLOT, SEPARATED EXACTLY BY PREDETERMINED FREQUENCY SPACING (B) FROM THE FREQUENCY RESOURCES TO WHICH THE PUCCH IS MAPPED, AND CYCLICALLY SHIFTS THE FREQUENCIES SO AS TO MAP THE PUCCH AND PUSCH TO FREQUENCY RESOURCES, WITHIN AN IDFT OR IFFT BANDWIDTH, OF A SECOND SLOT WHILE MAINTAINING THE PREDETERMINED FREQUENCY SPACING (B), THEREBY ALLOWING FREQUENCY HOPPING OF THE PUCCH AND PUSCH BETWEEN THE FIRST SLOT AND THE SECOND SLOT.

Abstract: The invention relates to a method for efficiently discarding data packets destined to a mobile station connected to both a master base station and a secondary base station. The master base station configures a secondary discard function in a lower layer of the secondary base station, based on the master discard function in the higher layer of the master base station. The master base station forwards the data packet from the higher layer to the lower of the secondary base station. The secondary discard function of the lower layer at the secondary base station discards the received data packet upon expiry of the secondary timer started by the lower layer upon reception of the data packet from the higher layer at the master base station.

Abstract: An image coding method using arithmetic coding. The method includes: performing arithmetic coding on a first flag (greater1_flag) that indicates whether or not an absolute value of a target coefficient in a target coefficient block is greater than 1 (S701); and performing arithmetic coding on a second flag (greater2_flag) that indicates whether or not the absolute value is greater than 2 (S702). In the arithmetic coding on the first flag and the arithmetic coding on the second flag, it is determined whether or not an immediately-prior coefficient block that has been coded immediately prior to the target coefficient block includes a coefficient having an absolute value greater than a threshold value (S711). Based on a result of the determination, respective contexts to be used in the arithmetic coding on the first and second flags are selected (S712).

Abstract: Por medio de la presente invención, el número de bits de codificación distribuidos a la codificación del espectro de banda extendida es reducido mientras es suprimida la degradación de la calidad de sonido en la banda extendida. Una unidad de compresión de banda (105) crea combinaciones de espectros de su banda en pares de dos muestras cada una en un orden a partir del lado de intervalo bajo en una subbanda de objetivo de compresión por banda, después, selecciona un espectro que tiene un valor absoluto entre las combinaciones, y coloca el espectro seleccionado junto al lado de intervalo bajo en el eje de frecuencia. Una unidad de recálculo de número de unidades (106) redistribuye los bits guardados en la subbanda para la cual fue realizada la compresión de banda en un intervalo bajo fuera de la banda extendida, y redistribuye el número de unidades en función de los bits redistribuidos.
