Ta timing advance
WebA method of managing multiple timing advance (TA) groups, maintaining multiple TA timers, and performing UL synchronization in a multi-carrier wireless system is provided. When a new component carrier (CC) is configured, it is assigned to a TA group having a TA group identifier. The TA groups are managed statically or dynamically. WebMay 20, 2024 · 1. GSM uses 6-bits to represent Timing Advance (TA). 2. TA value is therefore limited to the range 0 to 26-1, i.e 0 - 63 or (0 -233μs ). 3. Therefore, the maximum coverage distance of the GSM is calculation is as follows: 𝑅= 1 2 𝑏𝑁𝑏 where 𝑏 (1/(270.833x103) 𝑁𝑏 = 63bit is the maximum bit for time coordination (guard band)
