Claim:
A high speed uplink packet access adaptive retransmission method, characterized by comprising: obtaining, by a network device, a resource limitation state of a cell on basis of a load limitation state of the cell determined according to upper and lower received total wideband power (RTWP) thresholds for the cell; performing, by the network device, adjustment decision according to the resource limitation state of the cell obtained on basis of the load limitation state of the cell determined according to the upper and lower RTWP thresholds and a current target number of retransmissions of a UE; and adjusting, by the network device, according to a result of the adjustment decision performed according to the resource limitation state of the cell obtained on basis of the load limitation state of the cell determined according to the upper and lower RTWP thresholds, the target number of retransmissions of the UE between a preset large target number of retransmissions and a preset small target number of retransmissions, wherein the large target number of retransmissions is greater than the small target number of retransmissions, wherein the obtaining the load limitation state of the cell comprises: comparing, by the network device, an RTWP of the cell with the upper RTWP threshold; if the RTWP of the cell is higher than the upper RTWP threshold, determining that the load of the cell covering the UE is limited; and if the RTWP of the cell is lower than the upper RTWP threshold, determining that the load of the cell covering the UE is not limited; or comparing, by the network device, the RTWP of the cell with the upper RTWP threshold; if the RTWP of the cell is higher than the upper RTWP threshold, determining that the load of the cell covering the UE is limited; and if the RTWP of the cell is lower than the lower RTWP threshold, determining that the load of the cell covering the UE is not limited, wherein the upper RTWP threshold is higher than the lower RTWP threshold; wherein the performing of the adjustment decision comprises: adjusting the target number of retransmissions of the UE from the preset small target number of retransmissions to the lame target number of retransmissions, when the load of the cell that covers the UE is limited and the UE currently uses the small target number of retransmissions; and/or adjusting the target number of retransmissions of the UE from the preset lame target number of retransmissions to the small target number of retransmissions, when the load of the cell that covers the UE is not limited and the UE currently uses the lame target number of retransmissions.
