Simultaneous sharing of radio channel(s) inside one radio timeslot

- 1 FR channel shared : 2 FR users

- 2 HR channels shared : 4 HR users

In downlink

- The BTS transmits simultaneously to 2 MSs on the same timeslot and frequency

- Using two different Training Sequences (TSC)- With adaptive-QPSKmodulation

- -

(1,0) (0,0)

,to a different sub-channel

- Allows to double the throughput compared to legacy GMSK

- Variant of PSK allowin for inde endent ower control for the two users

I

In uplink

- 2 MSs transmit simultaneously on the same timeslot and frequency, using GMSK and different TSC

(1,1) (0,1)

- The BTS uses the different TSC to separate the signals from the two MSs


16/31


Two levels of VAMOS MSs

- eve : s a n a on are a e o use ra n ng sequences o e new se edefined in 3GPP for VAMOS MS

- Level 2: VAMOS-specific algorithms for interference cancellation instead of SAIC

Pairing is not limited to VAMOS mobiles

- Also possible with Legacy SAIC MS, as they are able to operate at low SIR values

- pa r ng s a owe u w a m e se o com na ons o e , o ensure

sufficient performance. There is therefore an impact on TSC planning

- Legacy non-SAIC mobiles could also support VAMOS operation but only if coupled to VAMOS Level 2 MS

VAMOS has low MS impacts;

BSS

Support by Twin TRX and MC-TRX/MC-RRH; Supported by BSC Evolution;

Pre-requisite: IP transport in BSS; ,


19/31


VAMOS allows to carry up to 4 calls per radio timeslot

- In TDM, existing mapping between one radio timeslot and one A-bis nibble does not work any more:16 kbits/s are not enough

A solution may consist in using two 16 kbits/s nibbles

- To avoid doubling the A-bis bandwidth requirements for voice, whereas only a part of the traffic will beusing VAMOS, dynamic allocation of one or two nibbles per radio timeslots (depending on whether

- This is a complex feature to implement in all network elements, whereas IP transport in the BSS allowsdynamic allocation natively

Alcatel-Lucent understand the significant efforts for its customers to move their transportlayer towards IP

Main target: Removal of TC from BSS: CAPEX gains Use TC resources in NGN Core

IP between core and BSC: Transmission costs reduction when BSC remains decentralized

Mixed Mode: in case of no / not enough TC resources in the Core + smoother migration No transcoding for intra-PLMN calls: BetterVoice Quality

TrFO should be easier than TFO in BSS Can be of interest for WB-AMR introduction
