Different Tasks and States of RRC Protocol in LTE-EUTRAN The RRC protocol for EUTRAN is responsible for the basic configuration of the radio protocol stack. But one should note, that some radio management functions (scheduling, physical resource assignment for physical channels) are handled by layer 1 and layer 2 autonomously. MAC and layer 1 signaling … Read more
The structure is based on the principle that the layers and planes are logically independent of each other. Protocol structures in UTRAN terrestrial interfaces are designed according to the same general protocol model. This model is shown in below. The structure is based on the principle that the layers and planes are logically independent of … Read more
UMTS Closed Loop Mode Transmit Diversity Used in DPCH and HS-PDSCH. The closed-loop-mode transmit diversity can only be applied to the UMTS downlink channel if there is an associated UMTS uplink channel. Thus this mode can only be used with UMTS dedicated channels. The chief operating principle of the closed loop mode is that the … Read more
Means for transmitting UE In order to avoid signaling of the radio access capability of the UE via an air interface at each transition from RRC_IDLE to RRC_CONNECTED, the core network stores AS capabilities (such as E-UTRA and the possibility GERAN), while the UE is in the RRC_IDLE / EMM-registered. After the connection S1, the … Read more
The E-UTRAN can configure the UE to report measurement information to support the control of UE mobility. The following measurement configuration elements can be signaled via the RRC Connection Reconfiguration message. E-UTRAN may configure the UE to report measurement information to support the control elements mobility. Following measurement configuration message can be supplied via the … Read more
Here I write on 3GPP Services Classification and EUTRAN Capacity Limiting Factors for LTE. 3GPP Services Classification Being a data centric technology, LTE has well defined classifications for Quality of Service. In general, there are two main classes of service type, with Guaranteed Bit rate vs with Non Guaranteed Bit rate. RT (Real Time) services … Read more
