Support for fixed wireless and vehicle mounted user equipment usage scenarios, with broader rural coverage and higher data rates is envisioned as part of deployment configurations in LTE band 12 and band 5 and band 13, and in NR band n5 and band n13 and band n71. Improvements in coverage, availability, and throughput performance to meet the market demands associated with fixed wireless and vehicle mounted usage would be enabled with user equipment specified with a power class 1 (31dBm) up-link transmission capability.
The fixed wireless access scenario provides a variety of benefits consisting of rapid deployment, and a reduction of costs associated with the transport to a customer premise, relative to wireline types of transport. The enablement of fixed wireless user equipment provides backhauling services to an appropriate base station in a serving network, for any other equipment at the customer premise. Similarly, vehicle mounted access scenario provides both direct access to other devices and indirect access to other devices, via the network.
The SI on High-power UE operation for fixed-wireless/vehicle-mounted use cases in Band 12, Band 5, and Band n71 is completed with the approval of
TR 37.880. Therefore, a WI can be started to further discuss and agree on the corresponding HPUE requirements in the RAN4 specifications.
This is a basket WI including following E-UTRA and NR bands.
As stated in the conclusion of
TR 37.880, the following topics should be further discussed and agreed during the WI phase:
Common Objectives:
-
UE MOP, MPR, and ACLR, considering the interactions between them (e.g. MRP and ACLR) and other related parameters
Band Specific objectives:
-
Coexistence studies between HPUE in Band 5 and adjacent channel public safety operation in the same geographical area.
-
UE REFSENS exception due to self-desens.
-
UE A-MPR, and impact of other related parameters (e.g. larger NR spectrum utilization for band n71).
-
Investigate the feasibility of filter with small duplex for B13, n13 and n71.
-
Coexistence study for B13 and n13.
The corresponding HPUE requirements for fixed wireless/vehicular-mounted use cases for each can be included in the RAN4 specifications independently when the work on this band is complete, i.e. no need to wait for the completion of other bands.
