Abstract
A multi-carrier terminal scheduling method and system are provided. The method includes, when accessing a network in an uplink, a multi-carrier terminal sending an uplink access request to a base station through an Enhanced Dedicated Channel Random Access Uplink Control Channel (E-RUCCH) over a carrier where a main frequency point selected by a wireless network controller for the multi-carrier terminal is located, and the base station scheduling the multi-carrier terminal through an Enhanced Dedicated Channel Absolute Grant Channel (E-AGCH). The system includes an access request transmission module located in the multi-carrier terminal and a scheduling module located in the base station for use in performing the method.
Claims7
A multi-carrier terminal scheduling method, comprising:
- a wireless network controller selecting a main frequency point for a multi-carrier terminal, and determining a carrier where the main frequency point is located as a sending carrier of E-Enhanced Dedicated Channel Random Access Uplink Control Channel (E-RUCCH);
- when accessing a network in an uplink, the multi-carrier terminal sending an uplink access request to a base station through the E-RUCCH over the sending carrier of the E-RUCCH;
- and
- the base station scheduling the multi-carrier terminal through an Enhanced Dedicated Channel Absolute Grant Channel (E-AGCH);
- wherein the step of the base station scheduling the multi-carrier terminal through the E-AGCH comprises:
- when the base station schedules the multi-carrier terminal, selecting some or all carriers supported by the multi-carrier terminal for scheduling, and sending authorization information to the multi-carrier terminal through the E-AGCH over the scheduled carrier;
- and
- after the multi-carrier terminal receives the authorization information sent by the base station, sending a serving and neighbor cell path loss (SNPL) value of the scheduled carrier and SNPL values of other carriers measured by the present terminal to the base station over the scheduled carrier through an enhanced dedicated channel physical uplink channel (E-PUCH);
- wherein, when the base station schedules the multi-carrier terminal for a first time, the authorization information is configured by the base station using a default value of the SNPL;
- and
- when the base station schedules the multi-carrier terminal again after scheduling for the first time, the authorization information is configured by the base station using the measured SNPL value of the scheduled carrier and the SNPL values of other carriers sent by the multi-carrier terminal.
A multi-carrier terminal scheduling system, comprising an access request transmission module and a scheduling module, wherein,
- the access request transmission module is located in the multi-carrier terminal, and configured to:
- when the multi-carrier terminal accesses a network in an uplink, send an uplink access request to a base station through an Enhanced Dedicated Channel Random Access Uplink Control Channel (E-RUCCH) over a carrier where a main frequency point selected by a wireless network controller for the multi-carrier terminal is located;
- and
- the scheduling module is located in the base station, and configured to schedule the multi-carrier terminal through an Enhanced Dedicated Channel Absolute Grant Channel (E-AGCH);
- the multi-carrier terminal scheduling system further comprises the wireless network controller, configured to select the main frequency point for the multi-carrier terminal, and determine a carrier where the main frequency point is located as a sending carrier of the E-RUCCH;
- wherein, the scheduling module is configured to schedule the multi-carrier terminal through the E-AGCH by means of:
- when scheduling the multi-carrier terminal, selecting some or all carriers supported by the mufti-carrier terminal for scheduling, and sending authorization information to the multi-carrier terminal through the E-AGCH over the scheduled carrier;
- and
- the system further comprises a signal quality information transmission module located in the terminal, configured to:
- after receiving the authorization information sent by the base station, send a serving and neighbor cell path loss (SNPL) value of the scheduled carrier and SNPL values of other carriers measured by the present terminal to the base station over the scheduled carrier through an enhanced dedicated channel physical uplink channel (E-PUCH);
- wherein, the system further comprises an authorization information configuration module located in the base station, configured to:
- configure the authorization information by using a default value of the SNPL when the base station schedules the multi-carrier terminal for a first time;
- and configure the authorization information by using the SNPL value of the scheduled carrier and the SNPL values of other carriers measured by the multi-carrier terminal sent by the multi-carrier terminal when the base station schedules the multi-carrier terminal again after scheduling for the first time.
