36.3315.5.2.9测量间隔配置

UE将：

1>如果measGapConfig设置为‘tup’，那么：

2>如果已经建⽴测量间隔配置，那么释放该测量间隔配置；

2>根据接收的gapOfft，建⽴measGapConfig表⽰的测量间隔，即，每⼀个间隔在SFN处开始，并且⼦帧满⾜如下条件：

SFNmodT=FLOOR(gapOfft/10);

subframe=gapOfftmod10;

其中T=MGRP/10，定义在TS36.133[16]中；

1>否则：

2>释放该测量间隔配置；

这取决于UE需要发送/接收间隙进⾏相关测量，测量分为间隙辅助或⾮间隙辅助。⾮间隙辅助测量是⼀种在不需要传输/接收间

隔（gap）的⼩区上的测量，以便允许进⾏测量。间隙辅助测量是⼀种测量在⼀个⼩区上，这是⼀个需要传输/接收间隙，以允

许测量进⾏测量。gap模式（相对于⾮gap模式）由rrc进⾏配置和激活

在enb调度过程中，对于配置了gap的ue，需要考虑的是

上⾏调度：

1.测量周期不可分配dci0

0分配的pusch不应在测量周期内

0分配的测量周期反馈的ack不应在测量周期内

下⾏调度：

1.测量周期不下发pdcch&pdsch

对应的ulack不应该在测量周期内
