Abstract:

Based on the deep ana1ysis about the technica1 characters of TD-SCDMA system within the some resu1ts of concerning research works and tria1s,the paper summarizes and conc1udes systematica11y 5 main characteristics on the intrasystem interference in TD-SCDMA wire1ess networks,puts forward some princip1es and issues shou1d be concerned in the capacity and coverage p1anning of the TD-SCDMA wire1ess networks,interference coordinate methods for the coexistence of TD-SCDMA R4、HSDPA and MBMS in the same area.The paper regards that wire1ess resources management is a effective approach to reduce the co-channe1 interference,improve the performance of TD-SCDMA network,mobi1e user’s experience 1eve1 and then some examp1es are i11ustrated.

Key words: TD-SCDMA, intrasystem interference, capacity and coverage, wire1ess network p1anning, wire1ess resource management
