Title:
A METHOD AND AN APPARATUS FOR PERFORMING NETWORK AIDED POWER SAVING IN NR UES IN DSS NETWORKS DEPLOYING TDM DSS PATTERNS
Document Type and Number:
WIPO Patent Application WO/2021/221403
Kind Code:
A1
Abstract:
The present invention generally relates to a wireless communication network, and more particularly, relates to Cellular Wireless Networks with Dynamic Shared Spectrum (DSS) feature enabled, and NR capable UEs. Specifically, to increase power save in 5G NR UEs, DSS networks that operate Time Division Multiplexed scheduling of LTE:NR downlink TTIs adopt an energy allocation strategy in the (RBs of) LTE guard bands. Such DSS networks indicate use of this strategy to 5G NR UEs that are in their coverage area, at the time of their respective initial attach procedures. 5G NR UEs in coverage of such DSS networks will be aware of the network strategy to allocate energy in (RBs of) LTE guard bands (only in the first symbol of every TTI). The 5G NR UEs avoid blind PDCCH decoding attempts in LTE operated downlink TTIs, and can turn off their NR receivers early.
