[0017] The following clearly describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative efforts fall within the scope of protection of the present application.

[0018] The terms "first," "second," etc., used in the specification and claims of this application are intended to distinguish between similar objects and are not intended to describe a specified order or sequence. It should be understood that such terms are interchangeable where appropriate, so that embodiments of this application may be performed in orders other than those illustrated or described herein, and that objects distinguished by "first" and "second" generally are of the same type and do not limit the number of objects; for example, a first object may be one or more. In the specification and claims, "and" indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between related objects.

[0019] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the described techniques may be used in the above-mentioned systems and radio technologies as well as other systems and radio technologies. However, although the following description describes New Radio (NR) systems for illustrative purposes and uses NR terminology in most of the following description, these technologies may also be used in applications other than NR system applications, such as sixth generation (6G) systems. th This may be applied to 6G (6th Generation) communication systems.

[0020] In this specification, a terminal may be referred to as a terminal device or user equipment (UE), and the terminal may be a terminal-side device such as a mobile phone, an integrated access and backhaul mobile termination (IABMT), a tablet personal computer, a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, a vehicle-mounted equipment (VUE), a pedestrian terminal (PUE), etc., and wearable devices include bracelets, earphones, glasses, etc. It should be noted that the embodiments of this application are not limited to a specific type of terminal.

[0021] In this specification, the network side equipment may be a base station or a core network, where the base station may be referred to as a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), or any other suitable term in the art, and as long as the same technical effect is achieved, the base station is not limited to the specified technical term. It should be noted that in the embodiments of this application, only base stations in an NR system are taken as examples, and the specific type of base station is not limited.

[0022] To facilitate understanding of the embodiments of the present application, the following technical points are introduced below.

[0023] (1) Measurement gap To perform PRS measurements, the terminal must measure within a measurement gap. Otherwise, the terminal is not expected to perform PRS measurements. A measurement gap may be understood as a periodic time interval during which the terminal suspends data / control signaling transmission and can only measure relevant signals, such as signals for positioning (e.g., PRS), signals for Radio Resource Management (RRM) (e.g., synchronization signals and PBCH blocks (SSBs)), etc.

[0024] For example, the measurement gap configuration in the prior art is included in the measurement interval configuration (MeasGapConfig) of Radio Resource Control (RRC) signaling.

[0025] The measurement gap period is {20, 40, 80, 160} milliseconds (ms) and the duration is {1.5, 3, 3.5, 4, 5.5, 6, 10, 20} ms. When a measurement gap is placed, data transmission is interrupted within the measurement gap.

[0026] Before receiving the measurement gap configuration, the terminal sends a measurement gap request to the serving new radio node (NR Node B, gNB) to assist the serving gNB in ​​configuring an appropriate measurement gap for positioning measurements. The request signaling includes information such as the terminal's desired measurement interval period, period offset, length, and measurement frequency bin.

[0027] 2. Positioning reference signal A positioning reference signal may include a PRS, a tracking reference signal (TRS), or other reference signals evolved for positioning, and this specification will use a PRS as an example.

[0028] The PRS is a downlink positioning reference signal for positioning, and is used by a terminal to perform positioning measurements. To complete positioning, the terminal needs to measure the PRSs transmitted by multiple cells.

[0029] Optionally, the period of the PRS is

number

[0030] According to related art, the measurement gap period is up to 160 ms, and a terminal may need to wait 160 ms to perform PRS measurement, which significantly limits the positioning delay. Note that the placement of the measurement gap also limits the flexibility of the PRS placement (the PRS period is much more flexible than the measurement gap).

[0031] 3 shows a block diagram of a wireless communication system to which the embodiments of the present application can be applied. The wireless communication system includes a terminal 31 and a network side device 32. Here, the terminal 31 may be referred to as a terminal device or user equipment (UE), and may be a terminal side device such as a mobile phone, a tablet personal computer (PDA), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, a vehicle-mounted equipment (VUE), a pedestrian-mounted equipment (PUE), etc., and wearable devices include a bracelet, an earphone, glasses, etc. It should be noted that the embodiments of the present application do not limit the specific type of the terminal 31. The network side equipment 32 may be a base station or a core network side equipment, where the base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), or any other suitable term in the art, and as long as the same technical effect is achieved, the base station is not limited to the specified technical term. It should be noted that in the embodiments of this application, only base stations in an NR system are taken as examples, and the specific type of base station is not limited.
