    • Techniques for performing system selection and acquisition are described. In one design, a terminal may obtain at least one system record for at least one system utilizing orthogonal frequency division multiplexing (OFDM) or single-carrier frequency division multiplexing (SC-FDM). Each system record may include system identification information for an associated system and an index for an associated acquisition record. The terminal may also obtain at least one acquisition record for the at least one system. Each acquisition record may include at least one value for at least one configurable system parameter, e.g., FFT size, cyclic prefix length, number of guard subcarriers, etc. The terminal may perform acquisition for the at least one system in accordance with the at least one system record and the at least one acquisition record. The system and acquisition records may be stored in a Preferred Roaming List (PRL) or a Most Recently Used (MRU) list.
    • 用于执行系统选择和采集技术进行了描述。 在一种设计中,终端可以获取至少一个系统用于记录至少一个系统利用正交频分复用(OFDM)或单载波频分复用(SC-FDM)。 每个系统记录可包括在相关联的系统和索引在相关联的采集记录系统识别信息。 因此,终端可获得至少一个采集记录的至少一个系统,每个采集记录可以包括用于至少一个可配置的系统参数,例如,FFT大小,循环前缀长度,保护子载波的数量等的至少一个值 该终端可以用于与所述至少一个系统记录和所述至少一个采集记录雅舞蹈的至少一个系统执行捕获。 该系统和采集记录可以存储在优选漫游列表(PRL)或最近使用的(MRU)列表。
