t sleep cycle is reset, if this value is included, the current sleep cycle is replaced by this value. Target Carrier Index Bitmap (4 bits) If the nth bit is set, it indicates that downlink data transmission on the secondary carrier whose logical carrier index is equal to (n + 1). MS Battery This header is used to inform the BS of Terminal's battery FID (4 bits) is flow identifier and is set to 0b0001. Level Report the terminal's battery level. The battery level reporting Type (5 bits) denotes the MAC signaling header level is defined as the amount of energy type. remaining in the battery as a percentage Length (3 bits) indicates the length of the signaling of full energy level. header in bytes. MS Battery Status (1 bit) indicates whether the MS is plugged into a power source. Battery Level Indication (1 bit) indicates whether the detailed battery level report is included. MS Battery Level (3 bits): Ob000: 75% < Battery Level <100%; 0b001: 50% < Battery Level <75%; 0b010: 25% < Battery Level <5%; 0b011: 5% < Battery Level <25%; Ob100: Battery level <5%. FID (4 bits) is flow identifier and is set to 0b0001.
