 CLC Active Cycle Type | CLC Class Example FIGURE 6-26 An illustration of system behavior during CLC active intervals [2] CHAPTER 6 The IEEE 802. 16m MAC CPS (Part I) BS via backhaul. The CLC active cycle and interval parameters remain the same. If the CLC active cycle is one frame, the MS uses a CLC active bitmap to configure a Type II CLC class. The bitmap is used to indicate the CLC active interval within the designated frame, where every bit in the bitmap corresponds to a subframe within the radio frame and, if set to 1, would indicate the corresponding subframe is a CLC active interval (i.e., non-IEEE 802.1 16m radio activity interval). 6.13 3GPP LTE RADIO RESOURCE CONTROL FUNCTIONS In 3GPP LTE, a user terminal can be in two different states, as shown in Figure 6-27. The Radio Resource Control (RRC) layer in the eNB makes handover decisions based on neighbor cell measurements sent by the UE, pages for the UEs over the air-interface, broadcasts system information, controls UE measurement reporting such as the periodicity of channel quality reports and allocates cell-level temporary identifiers to active UEs. It also executes transfer of UE context from the source eNB to the target eNB during handover, and performs integrity protection of RRC messages. The RRC layer is responsible for setup and maintenance of radio bearers. A UE is in RRC_CONNECTED state when an RRC connection has been established. If no RRC connection is established, the UE is said to be in RRC_IDLE state. The RRC states can further be characterized as follows: RRC_IDLE is a state where a UE specific Discontinuous Reception (DRX) may be configured by upper layers. In the idle mode, the UE is saving power and does not inform the network of each cell change. The network knows the location of the UE to the granularity of a few cells, called the Tracking Area (TA). The UE monitors a paging channel to detect incoming traffic, performs neighboring cell measurements and cell selection/reselection, and acquires system information. In brief, the RRC_I
