Abstract
Abstract A communication apparatus according to the present invention includes an RF signal processing means for processing a received RF signal, an RF demodulating means for demodulating an output signal of the RF signal processing means, a decoding means for decoding an output signal from the RF demodulating means, an encoding means for encoding a predetermined information signal, an RF modulating means for modulating an output signal from the encoding means, and a transmission signal processing means for processing an output signal from the RF modulating means. The encoding means includes a memory means for storing a predetermined control data, a selecting means for selecting the predetermined control data in accordance with an information of circuit quality obtained from the decoding means, and an adding means for adding the transmission data with an output of the selecting means. An output power of the transmission signal processing means is controlled by the information of the circuit quality.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
65 words
A communication method in a predetermined band
width with a predetermined format for multiple access by each
cell, comprising the steps of: a detecting step of detecting an interference to a
communication between a first apparatus and a second
apparatus by communication of a third apparatus; and a lowering step of lowering an information transmission
rate of said communication between said first and second
apparatus.
Claim 2
Dependent Claim
101 words
A communication method in a predetermined band
width with a predetermined format for multiple access by each
cell, comprising the steps of: a detecting step of detecting an interference to a
communication between a third apparatus and the other
apparatus by a communication between a first apparatus and a
second apparatus; an informing step of sending an information that said
interference is detected in said detecting step or an
information that existence of said interference is unknown to
said first or second apparatus; a lowering step of lowering an information transmission
rate of said communication between said first and second
apparatus.
Claim 3
Dependent Claim
99 words
A communication method in a predetermined band
width with a predetermined format for multiple access by each
cell, comprising the steps of: a detecting step of detecting a status that a first
base station is communicating with a subscriber in a cell
where said first base station is located and said subscriber
located at an edge of said cell where said first base station
is located is approaching to a cell where said second base
station is located; and a lowering step of lowering an information transmission
rate of said communication between said first base station
and said subscriber.
Claim 4
Dependent Claim
37 words
A communication method according to claim 2,
wherein said third apparatus is a base station of the other
cell, and a processing in said informing step is carried out
through a radio communication among plural base stations.
Claim 5
Dependent Claim
38 words
A communication method according to any one of
claims 1, 2 or 4, wherein a common frequency band for
communication is employed in a cell said first apparatus
belongs to and a cell said third apparatus belongs to.
Claim 6
Dependent Claim
34 words
A communication method according to claim 3,
wherein a common frequency band for communication is employed
in a cell said first base station belongs to and a cell said
second base station belongs to.
Claim 7
Dependent Claim
38 words
A communication method according to any one of the
preceding claims, wherein said predetermined format employs a
multicarrier signal formed by a unit which includes
subcarriers of a predetermined number and a time slots of a
predetermined number.
