example 1

[0163] Example 1: Signaling of an interference overload coded sequence. Directly use the interference overload coding sequence as the signaling of the interference overload indication (step S510).

[0164] use image 3 In the interference overload scenario shown, the schematic diagram of this embodiment is shown in Figure 5 shown. For spectrum resource blocks 1 to 10, the interference overload code on each spectrum resource block is 2 bits, and the signaling for interference overload indication is formed by cascading the interference overload codes of spectrum resource blocks 1 to 10, namely "01000001111000000000" , and its signaling overhead is 20 bits.

[0165] The base station that receives the interference overload indication combines the bit sequences in pairs into an interference overload code, and then decodes it according to Table 1, and obtains the interference overload levels of spectrum resource blocks 1 to 10 as "low, none, none, low , High, Medium, None, None...

example 2

[0167] Example 2: Signaling of an interference overload coded sequence. Directly use the interference overload coding sequence as the signaling of the interference overload indication (step S510).

[0168] use Figure 4 In the interference overload scenario shown, the schematic diagram of this embodiment is shown in Image 6 shown. For spectrum resource blocks 1 to 10, the interference overload code on each spectrum resource block is 2 bits, and the signaling for interference overload indication is formed by cascading the interference overload codes of spectrum resource blocks 1 to 10, namely "10010110111001010101" , and its signaling overhead is 20 bits.

[0169] The base station that receives the interference overload indication combines the bit sequences in pairs into an interference overload code, and then decodes it according to Table 2, and obtains the interference overload levels of spectrum resource blocks 1 to 10 as "medium, low, low, medium , High, Medium, Low, L...

example 3

[0171] Example 3: The concatenation of the index number interferes with the signaling of the overload coded sequence. For spectrum resource blocks with higher levels of interference overload, their index numbers are concatenated with corresponding interference overload codes to achieve a one-to-one correspondence between spectrum resource block index numbers and interference overload codes, and then all higher-level interference overload codes are The above-mentioned signaling set of the spectrum resource block is used as the signaling of the interference overload indication (step S510).

[0172] use image 3 In the interference overload scenario shown, the schematic diagram of this embodiment is shown in Figure 7 shown. "Low interference overload level", "medium interference overload level" and "high interference overload level" are regarded as higher-level interference overload. For spectrum resource blocks 1 to 10, the spectrum resource block with higher-level interferen...

Abstract

The invention provides an interference indication generating method, an interference indication triggering method, an interference indication method and a base station using the methods for an uplink FDMA cellular communication system. The base station comprises an interference overload indication triggering subsystem (1000), an interference overload indication generating subsystem (2000) and a transceiving subsystem (3000). The interference overload indication triggering subsystem (1000) firstly judges whether a triggering condition of interference indication is met. Only when the condition is met, the interference overload indication generating subsystem (2000) is triggered to operate so as to reduce the signaling overhead of the interference indication; and in order to further reduce the signaling overhead, interference indication signaling is generated and sent by adopting methods of differential coding, state coding, bit tables and the like. The invention has the advantages that a triggering mechanism of the interference indication is simple, the signaling overhead of the interference indication is lower, and the like.
