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.
Claims10
A method comprising:
- selecting a signature;
- transmitting a preamble using the signature;
- receiving a signal including an acquisition indicator, wherein the acquisition indicator corresponds to the signature;
- calculating a remainder of a division of an index of the signature by a number, wherein the number is a total number of enhanced dedicated channel (E-DCH) resource configurations minus a predetermined number;
- calculating a default E-DCH resource index X based on the remainder;
- and
- controlling an E-DCH transmission based on the default E-DCH resource index X in a case where the acquisition indicator is positive.
4 more elements
A user equipment comprising:
- a processor configured to select a signature;
- a transmitter configured to transmit a preamble using the signature;
- and
- a receiver configured to receive a signal including an acquisition indicator,
- wherein the acquisition indicator corresponds to the signature,
- wherein the processor is configured to calculate a remainder of a division of an index of the signature by a number,
- wherein the number is a total number of enhanced dedicated channel (E-DCH) resource configurations minus a predetermined number,
- wherein the processor is configured to calculate a default E-DCH resource index X based on the remainder, and
- wherein the processor is configured to control an E-DCH transmission based on the default E-DCH resource index X in a case where the acquisition indicator is positive.
6 more elements
A method comprising:
- receiving a preamble from a mobile station, wherein the preamble includes a signature;
- transmitting a first signal including an acquisition indicator, wherein the acquisition indicator corresponds to the signature;
- and
- receiving a second signal of an E-DCH based on 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 based on a remainder of a division of an index of the signature by a number, and
- wherein the number is a total number of enhanced dedicated channel (E-DCH) resource configurations minus a predetermined number.
3 more elements
A base station comprising:
