Section: 6.1.3.22 GNSS Measurement Command MAC Control Element
Content: The GNSS Measurement Command MAC Control Element is identified by a MAC PDU subheader with LCID as specified in table 6.2.1-1. It has a fixed size and consists of a single octet defined as follow (Figure 6.1.3.22-1): - T: The Type field is a flag indicating UE is triggered by network to perform GNSS measurement or just a GNSS measurement gap length is provided for UE-autonomous measurement. The T field set to "0" indicates UE needs to perform GNSS measurement with the GNSS measurement gap length configured in this MAC CE. The T field set to "1" indicates the GNSS measurement gap length configured in this MAC CE needs to be stored and used for the subsequent UE-autonomous GNSS measurement; - R: Reserved bit, set to 0; - GNSS Measurement Gap Length: the field corresponds to the configuration of GNSS measurement gap length as shown in Table 6.1.3.22-1. The length of the field is 4 bits. Figure 6.1.3.22-1: GNSS Measurement Command MAC control element Table 6.1.3.22-1: Values of GNSS Measurement Gap Length field
