How to increase data rates

Section 3

How to increase data rates General characteristics of the PHY layer

Context

Remember the Shannon formula C asymp nantW log2(1 + SINR)

In practice however This is a not achieved upper boundThis function is bounded (by Cmax) because we use finite modulationsCapacity should be shared by all active users in the cellSome resources should be dedicated to signaling

To increase data rates we have few options Increase W but issues with inter-symbol interferenceDecrease interference with lower frequency spatial reuse but lessbandwidth per cellIncrease Cmax by densifying the modulation but the signal is moresensitive to noise and interferenceIncrease nant but signal processing algorithm complexity increasesand space is needed for antennasDensify the network in order to decrease the number of users per cellbut more sites = more investments

The FFT spreads every QAM symbol over M sub-carriers

Every sub-carrier successively carriers all QAM symbols

At a given instant a unique QAM symbol is transmitted

The resulting PAPR is thus the same as for a QAM modulation

Contention-based access II1) The UE obtains from SIB the PRACH configuration the PRACH

frequency location the preamble format the target received powerand the list of sequences to be used (64 Zadoff-Chu sequencesincluding those reserved to the conflict-free access)

3) The UE chooses at random one sequence among those available4) It sends the preamble on the PRACH with an open loop power

control the UE tries to compensate the path-loss by usingmeasurements made on DL RSs rArr power control makes sequencedetection easier at the BS

Collision several UEs have used the same sequence on the same radioresourceCapture the eNB manages to decode one of the messages in collision

Contention-based access III

5) If there is no answer from the network power ramping (like inCDMA) ie the UE stepwise increases its transmit power

6) The RAR identifies the decoded preamble + provides the timingadvance (TA) + gives an UL allocation + a temporary identity(temporary C-RNTI address)

7) CCCH message on the PUSCH = eg a RRC connection request +temporary C-RNTI

8) Collision resolution the eNB sends a copy of the CCCH message onthe DL The UE that recognizes its message adopts the temporaryC-RNTI (now its address) other UEs leave the procedure

Conflict-free access

The UE has a valid identity (C-RNTI)The eNB sends a (DCI) message on the PDCCH including theZadoff-Chu sequence to be usedCollisions are no more possible no collision resolution phase
