Taking the BWP definition, and the fact that up to four BWP could be configured for a UE, different BWP allocation scenarios are possible and each could better serve certain use cases.
- Allocation (a): Supporting reduced UE bandwidth capability is especially helpful for devices with limited RF capability or those not capable of full carrier bandwidth.
- Allocation (b): Supporting reduced UE power consumption for intermittent and bursty traffic profiles.
- Allocation (c): Supporting two non-contiguous BWP with different numerologies allowing different services multiplexing.
- Allocation (d): Supporting non-contiguous spectrum, allowing services to be allocated between different BWPs. This is not yet part of Release 15 and could be added into future releases.
