In step S2101, the network apparatus 102 transmits first information to the terminal 101.

In some embodiments, the first information is used to "configure positioning reference signals PRS of the terminal".

In some embodiments, the name of the first information is not limited, and is, for example, "first configuration information" or the like.

In some embodiments, the first information includes at least one of: subcarrier spacing SCS of PRS; the number of time domain resource units occupied by PRS; the number of repeated transmissions of PRS; resource time interval of PRS; and the frequency hopping protection period of the PRS.

In some embodiments, the first information is carried by a medium access layer control element (Medium Access Controlcontrolelement, MACCE) or radio resource control (Radio Resource Control, RRC) signaling or downlink various control information (Downlink Control Information, DCI).

In some embodiments, terminal 101 is a reduced capability RedCap terminal.

In some embodiments, the terminal 101 supports receive hopping of PRSs.

In some embodiments, the number of hops depends on PRS configuration, e.g., how many repetitions are available for measurement at MG occasions, RF switching time, and the number of overlapping RBs between hops. The number of repetitions depends on the PRS configuration. The RF switch time has been agreed in the last RF conference as UE capability.

In some embodiments, in order to check whether the current measurement gap pattern is suitable for RAN1 protocol based Rx hopping, RAN4 needs to check how many hops can be allocated within the measurement gap duration.

In some embodiments, the preferred values for the number of repeated transmissions of PRS include {1,2,4,6,8, 16, 32}.

In some embodiments, the frequency hopping guard period of the PRS is a guard period between reception of a next hop from one hop to the next.

TABLE 1

Table 1 is a gap pattern configuration table when PRS SCS is 15k, allowing for multi-hopping within a single gap is not feasible for the maximum possible PRS configuration duration (e.g., DL PRS resource repetition factor=32) shown in table 1.

However, if we take some other possible configuration to evaluate the number of hops allowed, as shown in tables 2-4, we can observe that a pattern of most gaps is feasible.

For example, we list several possible combinations of parameters, as follows:

combination 1: scs=15 khz, dl-PRS-numsymbols=1, dl-PRS-resourcerepetationfactor=1, dl-PRS-resourcetimegap=1

Combination 2: scs=15 khz, dl-PRS-numsymbols=2, dl-PRS-resourcerepetationfactor=2, dl-PRS-resourcetimegap=1

Combination 3: scs=15 khz, dl-PRS-numsymbols=2, dl-PRS-resourcerepetationfactor=2, dl-PRS-resourcetimegap=2

TABLE 3 Table 3

TABLE 4 Table 4

From tables 1-4 we can conclude that:

it is not possible that all PRS configurations support multi-hops within a single measurement gap.

Any other enhanced measurement gap is introduced to allow.

PRS configurations with RX hopping should be limited according to existing gap patterns.
