US 2018/0324658 A1 · Packet-Switched Wireless Communication for Link Budget Limited Wireless Devices

Abstract

This disclosure relates to techniques for a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.

Claims20

Dependent claims

A user equipment (UE), comprising:

at least one antenna;
a radio coupled to the at least one antenna for performing wireless cellular communications;
and
at least one processing element coupled to the radio, wherein the at least one processing element is configured to:
indicate to a cellular base station that the UE is link budget limited;
provide configuration information to the cellular base station via an index value during random access channel (RACH) communication, wherein the configuration information specifies a set of one or more parameter values designed to provide improved performance for a link budget limited device, wherein the one or more parameter values are usable to configure the UE;
and
receive communication from the cellular base station based on the set of one or more parameter values.
