Fig. 2A is an interactive schematic diagram illustrating an information transmission method according to an embodiment of the present disclosure. As shown in fig. 2A, an embodiment of the present disclosure relates to an information transmission method, which includes:

in step S2101, the core network device 101, e.g., LMF, sends a first message to the access network device 102.

In some embodiments, the access network device 102 receives the first message.

In some embodiments, the first message is used for requesting the access network device to measure and report a measurement result according to an uplink positioning reference signal frequency hopping configuration.

In some embodiments, the uplink positioning reference signal may be an uplink positioning reference signal transmitted by the terminal 103, including but not limited to a channel sounding reference signal (Sounding Reference Signal, SRS).

In some embodiments, the terminal 103 hops to transmit the uplink positioning reference signal. For example, as shown in fig. 2B, the terminal 103 may hop and send the uplink positioning reference signal, where the terminal 103 sends the uplink positioning reference signal on different frequency domain resources at different time points. The frequency hopping for transmitting the uplink positioning reference signal can enable the access network device 102 to measure the uplink positioning reference signal on a larger bandwidth, thereby improving positioning accuracy.

When the terminal 103 hops to send the uplink positioning reference signal, two adjacent hops may have a gap (gap) in the time domain and may overlap in the frequency domain.

In some embodiments, the uplink positioning reference signal frequency hopping configuration refers to a relevant configuration of the terminal 103 for frequency hopping transmission of uplink positioning reference signals, including but not limited to time domain information transmission, frequency domain information transmission, and the like.

In some embodiments, the access network device 102 performs measurements according to an uplink positioning reference signal hopping configuration, where the obtained measurements include, but are not limited to, at least one of:

measuring a result value; a time stamp; measuring quality; measuring beam information; uplink positioning reference signal resource types; address resolution protocol (Address Resolution Protocol, ARP) identification; channel model information.

Wherein the measurement values may include, but are not limited to, at least one of: an uplink arrival angle; reference signal received power (Reference Signal Receiving Power, RSRP) of the uplink positioning reference signal; uplink relative arrival time (UpLink Relative Time of Arrival, UL RTOA); the transmission-reception time difference of the access network device 102; vertical angle of arrival (zenith Angle Of Arrival, z-AOA); a plurality of upstream arrival angles.

It should be noted that the measurement result is associated with the uplink positioning reference signal hopping configuration.

In some embodiments, the name of the first message is not limited, and is, for example, a request message, request signaling, first signaling, and the like.

In some embodiments, the first message may be a new air interface positioning protocol a (New Radio Positioning Protocol a, NRPPa) message.

In some embodiments, the first message may be a measurement request (MEASUREMENT REQUEST) message.

In some embodiments, the MEASUREMENT REQUEST message is sent by the core network device 101, e.g., LMF, to request the access network device 102, e.g., next generation radio access network (Next Generation Radio Access Network, NG-RAN) node, to configure the positioning measurements.

In some embodiments, the first message may include first frequency hopping information requesting uplink positioning reference signals measured by the access network device 102.

In some embodiments, the first frequency hopping information includes, but is not limited to, at least one of: the initial frequency domain unit index and the frequency domain unit number included by the uplink positioning reference signal resource; starting time units and the number of time units included in the uplink positioning reference signal resource; cycle duration and offset; uplink positioning reference signal sequence identification; number of hops; the number of time units between two adjacent hops; the number of frequency domain units overlapping two adjacent hops; and (5) frequency hopping index.

In one example, the frequency domain unit may be in units of Resource Blocks (RBs).

In one example, the time units may be in units of slots (slots), orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols, duration (span), which is not limited by the present disclosure. Wherein a span comprises a plurality of consecutive symbols.

In one example, the period duration refers to a period length of the terminal 103 for transmitting the uplink positioning reference signal in a frequency hopping manner, and the offset refers to an offset of a start time unit relative to a period start time unit.

In one example, the number of hops refers to the number of hops that the terminal 103 transmits the uplink positioning reference signal.

In one example, the frequency hopping index may be a positive integer, e.g., 1, 2, … …, indicating hop 1, hop 2 … ….

In some embodiments, the first frequency hopping information may include, but is not limited to, at least one of: one or more hopping group identifications; one or more uplink positioning reference signal resource identifiers.

The first frequency hopping information multiplexes the uplink positioning reference signal resource identifier to indicate.

Illustratively, each hop-group identity corresponds to one or more uplink positioning reference signal resource identities.

For example, if the first frequency hopping information sent by the core network device 101 includes the frequency hopping group identifier 1 and the frequency hopping group #1 corresponds to the uplink positioning reference signal resource #1 and the uplink positioning reference signal resource #2, the access network device 102 determines that the first frequency hopping information indicated by the core network device 101 includes the uplink positioning reference signal resource #1 and the uplink positioning reference signal resource #2.

Illustratively, when the hop-group identification is multiple, it may be sent to the access network device 102 in list form.

The core network device 101 illustratively sends one or more uplink positioning reference signal resource identifiers directly to the access network device 102.

Wherein the uplink positioning reference signal resource identifier is one or more, the core network device 101 may provide the access network device 102 with a plurality of uplink positioning reference signal resource identifiers through the uplink positioning reference signal resource identifier list.

For example, the first frequency hopping information transmitted by the core network device 101 includes an uplink positioning reference signal resource #1 and an uplink positioning reference signal resource #2.

In some embodiments, the first frequency hopping information may be carried in an SRS configuration (SRS configuration) information element of the measurement request message.
