smissions, and possible re-transmissions to UEs, where RRC defines the periodicity of the semi-persistent uplink grant and PDCCH indicates whether the uplink grant is a semi-persistent one, i.e., whether it can be implicitly reused in the following TTI according to the periodicity defined by RRC. In the subframes where the UE has a semi-persistent uplink resource, if the UE cannot find its C-RNTI on the PDCCH an uplink transmission according to the semi-persistent allocation that the UE has been assigned in the TTI can be made. The network performs decoding of the predefined physical resource blocks according to the predefined MCS. Otherwise, in the subframes where the UE has a semi-persistent uplink resource, if the UE finds its C-RNTI on the PDCCH, the PDCCH allocation overrides the persistent allocation for that TTI and the mobile terminal's transmission follows the PDCCH allo- cation. The re-transmissions are either implicitly scheduled where the UE uses the semi-persistent uplink allocation, or explicitly allocated via PDCCH where the UE does not follow the semi-persistent allocation. There is no blind decoding in uplink; therefore, when the UE does not have enough data to fill the allocated resource, padding is used. The measurement reports are required to enable the scheduler to operate in both uplink and downlink. These include transport volume and measurements of a user terminal's radio environment. The uplink Buffer Status Report (BSR) is needed to provide support for QoS-aware packet sched- uling. In E-UTRAN, uplink buffer status reports refer to the data that is buffered in for a group of radio bearers in the UE. Four radio bearer groups and two formats are used for reporting in uplink, i.e., a short format for which only one BSR is reported, and a long format for which all four BSRs are reported. Uplink buffer status reports are transmitted using MAC signaling. The time and frequency resources used by the UE to report CQI are under the control of the eNB. The CQI reporting can be either periodic or a
