CELL SEARCH PROCEDURE FOR TIME DIVISION DUPLEX COMMUNICATIONSYSTEMS USING CODE DIVISION MULTIPLE ACCESS |
摘要 |
A base station sends a synchronization signal in an assigned time slot to a user equipment in a time division duplex code division multiple access communication system. The base station has an assigned code group out of a predetermined number of code groups. The base station transmits selected secondary synchronization code signals out of a set of secondary synchronization code signals. The plurality of secondary synchronization code signals number s less than half of the predetermined number of code groups. The user equipmen t identifies the transmitted selected secondary code signals. Based on in part the identified secondary synchronization code signals, the assigned code group i s determined.
