Section: 6.1.3.16 AUL confirmation MAC Control Element
Content: The AUL confirmation MAC control element of one octet is identified by a MAC PDU subheader with LCID as specified in table 6.2.1-2. It has a fixed size and consists of a single octet containing seven C-fields and one R-field. The AUL confirmation MAC control element with one octet is defined as follows (figure 6.1.3.16-1). The AUL confirmation MAC control element of four octets is identified by a MAC PDU subheader with LCID as specified in table 6.2.1-2. It has a fixed size and consists of a four octets containing 31 C-fields and one R-field. The AUL confirmation MAC control element of four octets is defined as follows (figure 6.1.3.16-2). For the case with no serving cell with a ServCellIndex (TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [8]) larger than 7, AUL confirmation MAC control element of one octet is applied, otherwise AUL confirmation MAC control element of four octets is applied. - Ci: if there is an SCell configured with SCellIndex i as specified in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [8], this field indicates whether a PDCCH containing AUL activation or AUL release of the autonomous uplink configuration in the SCell with SCellIndex i has been received, else the MAC entity shall ignore the Ci field. The Ci field is set to "1" to indicate that a PDCCH containing AUL activation or AUL release of the autonomous uplink configuration in the SCell with SCellIndex i has been received in the TTI in which AUL confirmation has been triggered. The Ci field is set to "0" to indicate that a PDCCH containing AUL activation or AUL release of the autonomous uplink configuration in the SCell with SCellIndex i has not been received in the TTI in which AUL confirmation has been triggered; - R: Reserved bit, set to "0".
