Abstract
Aspects of the disclosure provide a method for observed time difference of arrival (OTDOA) positioning. The method can include receiving from a serving cell of a first network assistance data for measuring time difference of arrival of positioning reference signals (PRSs) received from a plurality of neighboring cells of a second network, receiving from the serving cell a gap pattern for decoding a master information block (MIB) of a first neighboring cell of the plurality of neighboring cells, or a system frame number (SFN) offset of the first neighboring cell, and determining an SFN timing of the first neighboring cell based on the gap pattern for decoding the MIB of the first neighboring cell or the SFN offset of the first neighboring cell.
Claims21
A method for observed time difference of arrival (OTDOA) positioning, comprising:
- receiving, by a user equipment (UE), assistance data from a serving cell of a first network, the assistance data for determining a time difference between the arrival of positioning reference signals (PRSs) received from a plurality of neighboring cells of a second network;
- receiving, by the UE, a gap pattern from the serving cell, the gap pattern for decoding a master information block (MIB) of a first neighboring cell of the plurality of neighboring cells, the gap pattern specifying starting times of multiple measurement gaps during which no uplink or downlink transmissions are scheduled for the UE;
- and
- determining, by the UE, a system frame number (SFN) timing of the first neighboring cell based on the gap pattern.
A method for observed time difference of arrival (OTDOA) positioning, comprising:
- transmitting, by a serving cell of a first network, assistance data to a user equipment (UE), the assistance data for determining a time difference between the arrival of positioning reference signals (PRSs) received from a plurality of neighboring cells of a second network at the UE;
- and
- transmitting, by the serving cell, a first gap pattern for decoding a master information block (MIB) of a first neighboring cell of the plurality of neighboring cells, the first gap pattern specifying starting times of multiple measurement gaps during which no uplink or downlink transmissions are scheduled for the UE.
(canceled)
A user equipment (UE) comprising:
- a memory storage comprising instructions;
- and
- one or more processor in communication with the memory, wherein the one or more processors execute the instructions to:
- receive assistance data from a serving cell of a first network, the assistance data for determining a time difference between the arrival of positioning reference signals (PRSs) received from a plurality of neighboring cells of a second network;
- receive a gap pattern from the serving cell, the gap pattern for decoding a master information block (MIB) of a first neighboring cell of the plurality of neighboring cells, the gap pattern specifying starting times of multiple measurement gaps during which no uplink or downlink transmissions are scheduled for the UE;
- and
- determine a system frame number (SFN) timing timing of the first neighboring cell based on the gap pattern.
A serving cell of a first network, the serving cell comprising:
- a memory storage comprising instructions;
- and
- one or more processor in communication with the memory, wherein the one or more processors execute the instructions to:
- transmit assistance data to a user equipment (UE), the assistance data for determining a time difference between the arrival of positioning reference signals (PRSs) received from a plurality of neighboring cells of a second network at the UE;
- and
- transmit a first gap pattern for decoding a master information block (MIB) of a first neighboring cell of the plurality of neighboring cells, the first gap pattern specifying starting times of multiple measurement gaps during which no uplink or downlink transmissions are scheduled for the UE.
