US 10,772,064 B2 · Positioning enhancements for narrowband internet of things

Abstract

Systems and methods of providing location techniques for a NB UE are described. The UE transmits, to a location server, a capability message that indicates position capabilities of the UE to support different positioning methods and common information related to the position methods, including that the UE is a NB UE. The UE receives a request for location information that includes a request for positioning measurements for a particular positioning method, a NB message size limit that indicates a limit on an amount of location information to return, and a NB response time to provide the positioning measurements. At least one of the response time or message size limit is different than for the NB UE than for non-NB UEs. The UE enters an idle state, performs the measurements, and transmits at expiry of or before the NB response time, a message containing the measurements.

Dependent claims

An apparatus of user equipment (UE), the apparatus comprising:

processing circuitry arranged to:
decode a request for location information Long Term Evolution (LTE) Positioning Protocol (LPP) message from a location server, the request for location information LPP message comprising a request for positioning measurements and a narrowband (NB) response time to provide the positioning measurements;
decode a Radio Resource Control (RRC) connection release message from an evolved NodeB (eNB) after reception of the request for location information LPP message;
enter an idle state in response to reception of the RRC connection release message;
after entry into the idle state, perform measurements indicated by the request for location information LPP message;
and
encode, for transmission to the location server within the NB response time to obtain the positioning measurements, at least one LPP Provide Location Information message containing the positioning measurements;
and
a memory configured to store the NB response time and the positioning measurements.

6 more elements

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE), the one or more processors to configure the UE to, when the instructions are executed:

transmit to a location server, a capability message that indicates position capabilities of the UE to support different positioning methods and common information related to a plurality of the position methods, wherein the information comprises an indication of a type of the UE, the type being narrowband (NB);
receive a request for location information Long Term Evolution (LTE) Positioning Protocol (LPP) message from a location server after transmission of the capability message, the request for location information LPP message comprising a request for positioning measurements and a NB response time to provide the positioning measurements, wherein the NB response time is longer than 128 seconds;
receive a Radio Resource Control (RRC) connection release message from an evolved NodeB (eNB) after reception of the request for location information LPP message;
enter an idle state in response to reception of the RRC connection release message;
after entry into the idle state, perform measurements indicated by the request for location information LPP message;
and
transmit, to the location server at expiry of or before the NB response time, at least one LPP Provide Location Information message containing the positioning measurements.
