摘要： In soft hand over in a code division multi access mobile radio communication system, interference in a down link caused by transmission from a plurality of base stations for one mobile station, can be restricted. Control of transmission power is performed according to command from the mobile station only in the base station serving as a primary base station which has minimum propagation loss with the mobile station during soft hand over, and the base stations other than the primary base station perform transmission with restricting output. In comparison with the transmission power control performed by the conventional plural base station transmission, interference for the peripheral mobile station can be reduced to achieve higher down link capacity. Also, upon restricting transmission power of the base station other than the base stations having small propagation loss with the mobile station among base station group in soft hand over, by moderately attenuating the transmission power instead of restricting abruptly, degradation of the reception quality can be prevented when error is caused in selection of the base station.

摘要： To prevent degradation of transmission quality due to interference between scramble codes, under such a situation as soft hand over, when the number of mobile stations connected with a base station exceeds the number of the orthogonal codes. The base station decides the priority of the scramble code. The scramble code is allocated to the mobile station, in accordance with the priority. When a mobile station ends its call, or stops temporarily its call, its PN code is re-allocated to the mobile station with lowest priority code.

摘要： In a method of controlling transmission power in a mobile station which switches a plurality of base stations from one to another with a hand-off time interposed on switching, an increase of the transmission power is suppressed with reference to reception levels of pilot signals sent from the plurality of the base stations which are divided into a first group of base stations under connection and a second group of base stations under non-connection. Specifically, the transmission power is slowly or gradually increased or kept constant when the reception level of the pilot signal sent from the second group base station exceeds that of the pilot signal sent from the first group base station.

摘要： Provided are a communication system and the like capable of making a stable relay route even when a propagation channel is fluctuated by the fluctuation of RSSI. For making a tree-type communication route whose root is a core node, each slave node, after the reception of the latest reset routing packet from a node, judges if the transmission source node should be the parent of the tree-type structure based on the sequential average of the reception power of n routing packets received from the same transmission source node. As the reception power is log-normally distributed in general, an asymptotically stable relay route can be obtained, especially by using the sequential average.
