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.
Claims8
A communications method, by a mobile station, comprising:
- selecting a signature;
- transmitting a first signal including the selected signature;
- receiving a second signal including an acquisition indicator corresponding to the selected signature;
- calculating a default E-DCH resource index X as X=Dind mod Y, wherein the Dind is an index of the selected signature and the Y is a total number of E-DCH resource configurations;
- controlling an E-DCH transmission using a first resource corresponding to the default E-DCH resource index X, in a case where the acquisition indicator is positive.
2 more elements
A mobile station comprising:
- a selector configured to select a signature;
- a transmitter configured to transmit a first signal including the selected signature;
- a receiver configured to receive a second signal including an acquisition indicator corresponding to the selected signature;
- a calculator configured to calculate a default E-DCH resource index X as X=Dind mod Y, wherein the Dind is an index of the selected signature and the Y is a total number of E-DCH resouce configurations;
- a transmission controller configured to control an E-DCH transmission using a first resource corresponding to the default E-DCH resource index X, in a case where the acquisition indicator is positive.
2 more elements
A communication method, by a base station, comprising:
- receiving a first signal including a signature selected by a mobile station;
- transmitting a second signal including an acquisition indicator corresponding to the signature;
- receiving a third signal of an E-DCH using a first resource corresponding to a default E-DCH resource index X in a case where the acquisition indicator is positive, wherein the dfault E-DCH resource index X is calculated as X=Dind mod Y, wherein the Dind is an index of the signature and the Y is a total number of E-DCH resource configurations.
A base station comprising:
- a receiver configured to reecive a first signal including a signature selected by a mobile station;
- and
- a transmitter configured to transmit a second signal including an acquisition indicator corresponding to the signature, wherein
- the receiver receives a third signal of an E-DCH using a first resource corresponding to a default E-DCH resource index X in a case where the acquisition indicator is positive, wherein the default E-DCH resource index X is calculated as X=Dind mod Y, wherein the Dind is an index of the signature and the Y is a total number of E-DCH resource configurations.
