ll edge UE. Further, the bandwidth allocation for cell edge users can be either static or dynamic. In static resource allocation, the frequency band for the cell edge users and cell center users are statically configured. In dynamic resource allocation, for each subframe, the target allocation bandwidth is determined by resource usage in past subframes. When the system is less loaded, all users will be scheduled within the edge band only when the system is overloaded beyond a particular threshold. Edge users will be scheduled in the edge band, and center users will be scheduled in the center band. RACH Optimization In LTE, a random access procedure can be performed by user equipment under the following conditions: IDLE user equipment performs an initial access procedure to move to the CONNECTED state. User equipment performs a handover to a target cell. When user equipment is in a CONNECTED state but out of time, synchronization occurs with the network, and it receives downlink data. When a UE is in a CONNECTED state but out of time, synchronization occurs with the network, and it attempts to transmit uplink data. When a UE performs reestablishment after it detects a radio link failure. Need for RACH Optimization In a homogenous network wherein the neighboring cells are using the same center frequency for uplink transmission, PRACH planning becomes very important and can very well be performed using self-optimization techniques. User equipment that intends to move from an IDLE to a CONNECTED state to send or receive data will need to first perform a RANDOM ACCESS procedure. CHAPTER 2 SELF-ORGANIZING NETWORKS IN LTE DEPLOYMENT The necessarily cell-specific RANDOM ACCESS procedural details are provided to the UE in systemInformationBlockType2( (SIB2). Each of these broadcasted SIB2 parameters can be fine tuned or optimized by the network in order to: Optimize the balance between the RANDOM ACCESS opportunities and UL data transfer. This is especially a concern in TDD modes of operation where there are not too many
