Embodiment 1
[0028] Embodiment 1 of the present invention provides a PDSCH power allocation method, which dynamically adjusts the PDSCH transmission power based on the downlink path loss (PL) of the UE, thereby reasonably allocating the PDSCH transmission power and effectively reducing the downlink interference between cells, such as figure 1 As shown, the method includes the following steps:
[0029] Step 101, the base station equipment obtains downlink path loss information corresponding to the UE.
[0030] In the embodiment of the present invention, the base station device can periodically obtain the downlink path loss information corresponding to the UE, and the process of obtaining the downlink path loss information corresponding to the UE specifically includes: the base station device calculates the downlink path loss information PL corresponding to the UE through the following formula avr_n :
[0031] PL avr_n = γ·PL n +(1-γ)·PL avr_n-1
[0032] Among them, PL avr_n-1 is the d...
Embodiment 2
[0070] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a base station device, such as figure 2 As shown, the base station equipment includes:
[0071] An obtaining module 11, configured to obtain downlink path loss information corresponding to the user equipment;
[0072] The determination module 12 is configured to determine the power adjustment step size corresponding to the downlink path loss information by querying the correspondence between the path loss threshold interval and the power adjustment step size;
[0073] The allocation module 13 is configured to allocate the current PDSCH transmission power of the user equipment according to the power adjustment step size and the average transmission power of the downlink PDSCH unit resource element RE.
[0074] The obtaining module 11 is specifically configured to calculate the downlink path loss information PL corresponding to the user equipment through the fol...
