Abstract
A wireless communications network includes a mobile station and wireless access equipment. In communications between the wireless access equipment and the mobile station (such as in the forward link), a data rate is specified. However, the effective data rate can be reduced (with respect to the specified data rate) if it is determined that the specified data rate is not needed. In one arrangement, the effective data rate is reduced by waiting to fill a physical layer packet before transmission.
Claims26
A method of wireless communication, comprising:
- receiving an indication of a data rate for communicating data over a wireless link between a mobile station and wireless access equipment;
- determining whether the data rate specified by the indication is greater than a rate at which data to be communicated over the wireless link is received by one of the mobile station and wireless access equipment;
- and
- reducing an effective data rate of communicating data over the wireless link in response to a determination that the data rate specified by the indication is greater than the rate at which data to be communicated over the wireless link is received.
An article comprising at least one storage medium containing instructions that when executed cause a system to:
- provide a scheduling procedure for wireless communications between a mobile station and a wireless access equipment;
- receive a specified data rate for the wireless communications;
- and
- provide an effective data rate that is different from the specified data rate in response to determining that the specified data rate is greater than a rate at which data to be communicated wirelessly is received by one of the mobile station and the wireless access equipment.
A wireless network control apparatus, comprising:
- an interface to a wireless link for communicating wirelessly with a mobile station;
- and
- a controller adapted to:
- receive a specified data rate for communicating data with the mobile station,
- determine whether the specified data rate is greater than a rate at which data to be communicated wirelessly is received by the wireless network control apparatus, and
- provide an effective data rate in communicating the data with the mobile station, the effective data rate being different from the specified data rate, in response to determining that the specified data rate is greater than the rate at which data to be communicated wirelessly is received by the wireless network control apparatus.
