Abstract
It is possible to solve the problem that a downstream control information amount is significantly increased if allocation information is periodically reported because no allocation method of a default E-DCH resource configuration is defined for a preamble signature. A base station and a mobile station decide a default resource configuration by using a total number of resource configurations or a value obtained from the total number.
Claims6
A base station, wherein said base station receives a preamble transmitted by a mobile station, and transmits a response to the received preamble to said mobile station, and in a case that said response is a first response, said mobile station transmits data using information about at least a part of a default resource configuration of the own mobile station that is determined using the total number of resource configurations or a value obtained from said total number,
- wherein:
- said base station prepares a plurality of said default resource configurations for each said preamble signature,
- said base station prepares a plurality of values of a parameter for calculating said default resource configuration, selects a value of said parameter, and broadcasts it, and
- said parameter is comprised of a positional offset and a spacing offset, and said base station calculates a default resource configuration Dind for each group as Dind=(Cj*PreInd+Bi) mod Y, where the positional offset is designated as Bi (i=1, . . . , N;
- N is a natural number), and the spacing offset is designated as Cj (j=1, . . . , L;
- L is a natural number).
A mobile station for transmitting a preamble to abuse station,
- wherein:
- said mobile station transmits a preamble to a base station and receives a response to said preamble from said base station,
- in a case that said response is a first response, said mobile station transmits data using information about at least a part of a default resource configuration of the own mobile station that is determined using the total number of resource configurations or a value obtained from said total number,
- said default resource configurations are prepared each said preamble signature by base station which prepares a plurality of values of a parameter for calculating said default resource configuration, selects a value of said parameter, and broadcasts it, and
- said parameter is comprised of a positional offset and a spacing offset, and said base station calculates a default resource configuration Dind for each group as Dind=(Cj*PreInd+Bi) mod Y, where the positional offset is designated as Bi (i=1, . . . , N;
- N is a natural number), and the spacing offset is designated as Cj (j=1, . . . , L;
- is a natural number).
A response determination method for a base station,
- comprising receiving a preamble transmitted by a mobile station and transmitting a response to the received preamble to said mobile station, and in a case that said response is a first response, said mobile station transmitting data using information about at least apart of a default resource configuration of the own mobile station that is determined using the total number of resource configurations or a value obtained from said total number,
- wherein:
- said base station prepares a plurality of said default resource configurations for each said preamble signature,
- said base station prepares a plurality of values of a parameter for calculating said default resource configuration, selects a value of said parameter, and broadcasts it, and
- said parameter is comprised of a positional offset and a spacing offset, and said base station calculates a default resource configuration Dind for each group as Dind=(Cj*PreInd+Bi) mod Y, where the positional offset is designated as Bi (i=1, . . . , N;
- N is a natural number), and the spacing offset is designated as Cj (j=1, . . . , L;
- L is a natural number).
A resource configuration determination method for a mobile station, comprising:
- said mobile station transmitting a preamble to a base station and receiving a response to said preamble from said base station,
- determining a default resource configuration of the own mobile station using the total number of resource configurations or a value obtained from said total number, and
- in a case that said response is a first response, said mobile station transmitting data using information about a least a part of a default resource configuration of the own mobile station,
- wherein:
- said default resource configurations are prepared each said preamble signature by base station which prepares a plurality of values of a parameter for calculating said default resource configuration, selects a value of said parameter, and broadcasts it, and
- said parameter is comprised of a positional offset and a spacing offset, and said base station calculates a default resource configuration Dind for each group as Dind=(Cj*PreInd+Bi) mod Y, where the positional offset is designated as is a natural number), and the spacing offset is designated as Cj (j=1, . . . , L;
- L is a natural number).
A non-transitory computer readable medium storing a program for causing an information processing apparatus to execute processing, said program causing said information processing apparatus to execute a process of receiving a preamble transmitted by a mobile station and transmitting a response to the received preamble to said mobile station, and in a case that said response is a first response, said mobile station transmitting data using information about at least a part of a default resource configuration of the own mobile station that is determined using the total number of resource configurations or a value obtained from said total number,
- wherein:
- said information processing apparatus prepares a plurality of said default resource configurations for each said preamble signature,
- said information processing apparatus prepares a plurality of values of a parameter for calculating said default resource configuration, selects a value of said parameter, and broadcasts it, and
- said parameter is comprised of a positional offset and a spacing offset, and said information processing apparatus calculates a default resource configuration Dind for each group as Dind=(Cj*PreInd+Bi) mod Y, where the positional offset is designated as Bi (i=1, . . . , N;
- N is a natural number), and the spacing offset is designated as Cj (j=1, . . . , L;
- L is a natural number).
A non-transitory computer readable medium storing a program for causing an information processing apparatus to execute processing, said program causing said information processing apparatus to execute a process of determining a default resource configuration in a mobile station using the total number of resource configurations or a value obtained from said total number, said mobile station transmitting a preamble to a base station and receiving a response to said preamble from said base station, and in a case that said response is a first response, said mobile station transmitting data using information about at least a part of a default resource configuration of the own mobile station;
- wherein:
- said default resource configurations are prepared each said preamble signature by base station which prepares a plurality of values of a parameter for calculating said default resource configuration, selects a value of said parameter and broadcasts it, and
- said parameter is comprised of a positional offset and a spacing offset, and said base station calculates a default resource configuration Dind for each group as Dind=(Cj*PreInd+Bi) mod Y, where the positional offset is designated as Bi (i=1, . . . , N;
- N is a natural number), and the spacing offset is designated as Cj (j=1, . . . , L;
- L is a natural number).
