Packet-Switched Wireless Communication for Link Budget Limited Wireless Devices

摘要

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.

主权项

1. A user equipment (UE), comprising:
at least one antenna; a radio coupled to the at least one antenna for performing wireless cellular communications; at least one processing element coupled to the radio; wherein the UE is configured to:
connect to a base station of a first cell in a cellular network, wherein the UE is link budget limited;perform a measurement of signal to interference noise ratio (SINR) of communications received by the UE in the first cell;generate a received signal power value based at least in part on the SINR measurement, wherein the UE generates 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 adequate SINR; andcommunicate the generated received signal power value to the base station as a received signal power measurement, wherein the generated received signal power value is used by the base station in determining when a handover of the UE should occur from the first cell to a second cell.
