Patent

CA 2278755

Mobile station radio communication equipment MS is provided with a transmission-reception amplifying section AMP, a radio communication section TRX, a base-band signal processing section BB, a mobile station control section MS-CNT, and a terminal interface section TERM-INT. In multi-code transmission, the availability of a frequency resource and communication quality are improved by transmitting control information (pilot symbol and TPC symbol) only with one designated individual physical channel boosted in electric power. In addition, the availability of the frequency resource and communication quality are improved and, at the same time, the power consumption is reduced by deciding the transmission/cancellation of transmission information in accordance with the communication quality and communication state. Moreover, the availability of the frequency resource is improved and the power consumption is reduced by avoiding the occurrence of frequent calls.

Le matériel de radiocommunications d'une station mobile (SM) comprend une partie (AMP) amplifiant l'émission-réception, une partie radiocommunications (TRX), une partie (BB) traitement du signal de la bande de base, une partie commande (CM) de la station mobile et une partie (INT-TERM) interface de terminal. Dans l'émission multicode on améliore la disponibilité d'une ressource de fréquence et la qualité de la communication par la transmission d'informations de commande (symbole pilote et symbole TPC) sur un seul canal physique individuel désigné qui est suralimenté en puissance électrique. On améliore également la disponibilité de la ressource de fréquence et la qualité de la communication et dans le même temps on réduit la consommation de puissance en décidant de la transmission/annulation des informations de transmission en fonction de la qualité de la communication et de l'état de cette dernière. En outre on améliore la disponibilité de la ressource de fréquence et on réduit la consommation de puissance en empêchant des appels fréquents de se produire.
