MAC notifies RLC of a transmission opportunity asking for data each TTI. So does RLC respond with multiple PDUs one for each UE (with different RLC SNs for each of the PDU). Or just sends down one PDU (with one RLC SN) having data of all the scheduled UEs? This same question could be put this way too: Are the RLC SNs assigned independently for each UE or are they assigned by incrementing by 1 every TTI?
As per 3gpp 36.322 Release 12.0 RLC specification, Extended RLC LI field = 15 bit is newly included in AM mode. Can anyone please explain, exactly in what condition this 15-bit LI value will be used.
Can anyone please provide some detailed information about these two?
