WebBSR (Buffer Status Report) BSR is a kind of MAC CE from UE to Network carrying the information on how much data is in UE buffer to be sent out. Putting it another way, it is a kind of MAC layer message from UE to Network (eNodeB) saying "I have something to transmit, would you give me a Grant to send this data ?" WebF stands for 'Format'. It indicates the size of the Length field. There is one F field per MAC subheader except for subheaders corresponding to fixed-sized MAC CEs and padding. The size of the F field is 1 bit. 0 indicates 8 bits of the Length field. 1 indicates 16 bits of the Length field. Followings table shows the LCID field in MAC Subheader ...

WebBSR REIT WebYou would see that the length of PRACH preamble varies depending on the preamble format. For example, the length of PRACH with preamble format 0 is (3186 + 24567) Samples. (As you know, one sample (Ts) is 1/30.72 (=0.03255) us. It is defined as 1/ (15000 x 2048) seconds (=0.03255 us) in 36.211 4 Frame structure). buses from st pancras to marble arch

Webii) If you have access to eNB log, you have to check the data transmission status at each subframe and confirm that there is no data transmission at MAC/PHY level. iii) If you have access to UE log, you have to check the data reception or SR (Scheduling Request) / BSR (Buffer Status Report) for long enough to trigger CDRX sleep mode. Webi) Transmit send a signal to reciever. ii) Reciever measure the power of the signal from the transmitter. iii) if the measured power is too low, the reciever send a special command saying "increase the power". And if the measured power is too strong, it would send another command saying "decrease the power".
