– A resource grid is characterized by one subframe in time domain and full carrier bandwidth in the frequency domain . – There are a set of resource grids per transmission direction (uplink or downlink).
Read moreWhat is SSF in LTE?
A Special subframe has three past DwPTS(Downlink Pilot Time Slot),GP (Guard Period) and UpPTS (Uplink Pilot Time Slot) and all of these have configurable lengths while the sum of the lengths has to be 1 ms or 14 symbols.
Read moreWhat is HARQ in LTE?
HARQ stands for Hybrid Automatic Repeat Request . HARQ = ARQ + FEC (Forward Error Correction)/Soft Combining. ARQ refers to Automatic Repeat Request i.e. if sender doesn’t receive Acknowledgement (ACK) before timeout, the receiver discards the bad packet and sender shall re-transmits the packet.18 Eki 2018
Read moreHow many HARQ process in LTE?
The eNodeB will keep transmitting the same transport block using different RV values until the UE receives an error free transport block or the total retransmission limit occurs. In LTE the total number of HARQ processes which can be initiated at any given time is 8 .
Read moreHow many slots are in a subframe?
Each of sub frame consists of 2 slots , each of which is 0.5 ms in length.
Read moreHow many symbols are there in LTE frame?
A typical LTE frame is 10 ms (milliseconds) long. Each LTE frame has 10 sub-frames (1 ms each) while each sub-frame is further divided into 2 slots (0.5 ms each). The slots are divided into symbols – each slot has either 6 or 7 symbols .
