Abstract
A communication resource that includes a communication channel is allocated in response to a received communication resource access request, wherein the access request is received while a message received via the communication channel is being demodulated. In response to receiving the request, a grant of access to the communication channel is generated and transmitted, which grant authorizes the source of the access request to use the communication channel.
Claims21
In a broadband communication system, a method for allocating a communication resource that comprises a reverse link traffic channel, the method comprising steps of:
- receiving a communication resource access request at a time that data received via the reverse link traffic channel is currently being demodulated;
- and
- in response to receiving the communication resource access request, transmitting a grant of access to the reverse link traffic channel wherein the step of transmitting a grant of access to the reverse link traffic channel comprises steps of:
- determining a time that a demodulator will be available;
- determining a time that a grant of access to the reverse link traffic channel can be transmitted based on the time that the demodulator will be available;
- and transmitting an access grant based on the received request and on the determined time that the grant of access to the reverse link traffic channel can be transmitted.
An apparatus for allocating a communication resource in a broadband communication system, wherein the communication resource comprises a reverse link traffic channel, the apparatus comprising:
- an access request detector that detects a receipt of a communication resource access request;
- a demodulator that is capable of demodulating messages received via the reverse link traffic channel;
- a means for generating a grant of access to the reverse link traffic channel and the demodulator in response to reception of the communication resource access request;
- and
- wherein the communication resource access request is received at a time that the demodulator is engaged in a demodulation of a message received via the reverse link traffic channel wherein the means for generating a grant of access to the reverse link traffic channel comprises:
- a means for determining a time that a demodulator will be available;
- a means for determining a time of transmission of a grant of access to the reverse link traffic channel based on the determined time of demodulator availability;
- and a means for generating an access grant based on the received communication resource access request and on the determined time of transmission of the access grant.
A communication device capable of operating in a broadband communication system, the communication device comprising:
- a receiver for receiving an communication resource access request;
- an access request detector coupled to the receiver that detects a receipt of the communication resource access request;
- a demodulator coupled to the receiver that is capable of demodulating messages received via reverse link traffic channel;
- a means for generating a grant of access to the demodulator in response to reception of the communication resource access request;
- a modulator for modulating the access grant onto a radio frequency signal to produce a modulated access grant;
- a transmitter for transmitting the modulated access grant and
- wherein the communication resource access request is received at a time that the demodulator is engaged in a demodulation of a message received via the reverse link traffic channel wherein the means for generating a grant of access to the reverse link traffic channel comprises:
- a means for determining a time that the demodulator will be available;
- a means for determining a time of transmission of a grant of access to the reverse link traffic channel based on the determined time of demodulator availability;
- and a means for generating an access grant based on the received communication resource access request and on the determined time of transmission of the access grant.
