The cellular phone and smart home devices communicate without relaying the communication signal through the base station.

[0035] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. A base station can broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. A base station can also refer to a communication module, a modem or a chip used to be set in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs base station functions in device-to-device D2D, vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. The base station can support networks with the same or different access technologies.

[0039] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0040] Positioning Technology in Communication Systems

[0041] Referring to Figure 2, the communication system 100 may further include a positioning device 130. The positioning device 130 may be used to determine the location information of the terminal device. The positioning device 130 may be located in the core network. The positioning device 130 may sometimes also be referred to as a positioning server. Taking the NR system as an example, the positioning device 130 may be a location management function (LMF). Taking other communication systems as an example, the positioning device 130 may be a location management unit (LMU), a location management center (LMC) or an evolved serving mobile location center (E-SMLC). It is understandable that the positioning device 130 may also be other network elements, nodes or devices for determining the location information of the terminal device, such as a network element or node for determining the location information of the terminal device in a future communication system. The embodiment of the present application does not specifically limit the name of the positioning device.

[0042] Positioning in the communication system 100 includes uplink positioning and downlink positioning. Some communication systems (such as NR systems) perform downlink positioning based on a positioning reference signal (PRS). PRS, also known as a downlink positioning reference signal (DL-PRS), is a reference signal used for positioning functions. For example, in the downlink positioning process, the terminal device 120 can first measure the PRS sent by the serving cell and the neighboring cell (or adjacent cell), and estimate the relevant information of the positioning measurement. Then, the terminal device 120 can report the relevant information of the positioning measurement as a measurement result of the PRS to the positioning device 130. The positioning device 130 can solve the position of the terminal device 120 based on the positioning measurement related information reported by the terminal device 120, thereby obtaining the position information of the terminal device 120. For example, the positioning device 130 can calculate the position information of the terminal device 120 based on the triangulation method or the triangulation method.

[0043] Some communication systems (such as NR systems) perform uplink positioning based on SRS. For example, during the uplink positioning process, the terminal device 120 sends an SRS. The network device 110 (the network device of the serving cell and the network device of the neighboring cell) can obtain a measurement result based on the SRS sent by the terminal device 120. The measurement result of the SRS may include relevant information of the positioning measurement. Then, the network device 110 can send the relevant information of the positioning measurement to the positioning device 130. The positioning device 130 can solve the position of the terminal device 120 based on the positioning measurement related information reported by the network device 110, thereby obtaining the position information of the terminal device 120. For example, the positioning device 130 can calculate the position information of the terminal device 120 based on the triangulation positioning method or the triangulation positioning method.

[0044] The above-mentioned positioning measurement related information may include one or more of the following information: time information, distance information, power information, and angle information. More specifically, the positioning measurement related information may include one or more of the following information: time difference of arrival (TDOA), angle difference of arrival (ADOA), reference signal receive power (RSRP), etc.

[0045] DRX mode

[0046] When a terminal device adopts the DRX mode (DRX mechanism), the terminal device can periodically enter a sleep state at certain times and not monitor the physical downlink control channel (PDCCH); when it needs to monitor the PDCCH, the terminal device can wake up from the sleep state. The terminal device adopts the DRX mode to enable the terminal device to save power. In some cases, the terminal device's adoption of the DRX mode may have a certain impact on the data transmission delay (for example, the data transmission delay increases), but if the increased delay does not affect the user experience, then considering the UE's power consumption, it makes sense for the terminal device to perform DRX.

[0047] The implementation of the DRX mechanism may differ in different radio resource control (RRC) states. For example, the implementation of the DRX mechanism in the RRC Idle state / RRC Inactive state may differ from the implementation of the DRX mechanism in the RRC Connected state. Relatively speaking, the implementation of the DRX mechanism in the RRC Connected state is more complex. In some implementations, the DRX mechanism in the RRC Idle state and / or RRC Inactive state may also be referred to or understood as a paging mechanism.

[0048] Figure 3 is a schematic diagram of a DRX cycle. As shown in Figure 3, T1 is the terminal device wake-up time, also known as the DRX on-duration. T2 is the terminal device sleep time, also known as the DRX opportunity.

[0049] The duration of the terminal device's wake-up time can be controlled by the DRX duration timer (drx-onDurationTimer). The duration of the DRX duration timer is T1. The terminal device needs to continuously monitor the PDCCH during the wake-up time T1, but does not need to monitor the PDCCH during the sleep time T2. It is understood that the longer the T2 time, the lower the energy consumption of the terminal device.

[0050] As can be seen from Figure 3, for a long DRX cycle, the terminal device wakes up less frequently, so it is more power-saving for the terminal device; while for a short DRX cycle, the terminal device wakes up more frequently, which increases the energy consumption of the terminal device, but can increase the probability of the network device successfully scheduling the terminal device and reduce data transmission delay.

[0051] Each medium access control (MAC) entity corresponds to a DRX configuration (a DRX configuration may include one or more DRX parameters), or in other words, each MAC entity corresponds to one or more DRX parameters. The DRX configuration may include the aforementioned DRX duration timer. In addition, the DRX configuration may also include other DRX timers, which are used together to adjust the wake-up time of the terminal device.

[0052] The other DRX timers mentioned here may include, for example, one or more of the following timers: DRX deactivation timer (drx-InactivityTimer), short DRX cycle timer (drx-ShortCycleTimer), DRX downlink retransmission timer (drx-RetransmissionTimerDL), and DRX downlink hybrid automatic repeat reQuest (hybrid automatic repeat reQuest, HARQ) round-trip time (RTT) timer (HARQ-RTT-TimerDL).

[0053] The DRX deactivation timer can indicate how long the terminal device needs to continue monitoring after successfully detecting the PDCCH. The short DRX cycle timer can indicate how long the terminal device continues to follow the short DRX cycle. The DRX downlink retransmission timer can be used for the terminal device to receive downlink retransmission scheduling. This timer can indicate the length of time the terminal device needs to continuously monitor in order to receive the expected downlink retransmission scheduling. The DRX downlink hybrid automatic repeat request round-trip time (RTT) timer (HARQ-RTT-TimerDL) is used for the terminal device to receive downlink retransmission scheduling. It indicates the length of time the terminal device needs to wait before receiving the expected downlink retransmission scheduling.

[0054] In addition, the network device can also configure other DRX parameters for the terminal device, such as the short DRX cycle, the long DRX cycle, the DRX start subframe offset (drx-LongCycleStartOffset), the DRX time slot offset (drx-SlotOffset), etc.; and configure other DRX timers, such as the random access contention resolution timer (ra-ContentionResolutionTimer), the DRX uplink retransmission timer (drx-RetransmissionTimerUL), the DRX uplink HARQ round-trip time timer (HARQ-RTT-TimerUL), etc.

[0055] In the DRX mechanism, the configuration of the long DRX cycle can be the default configuration, and the configuration of the short DRX cycle can be an optional configuration. For a terminal device configured with a short DRX cycle, the long DRX cycle and the short DRX cycle can be switched between in the following ways:

[0056] When any of the following conditions are met, the terminal device uses a short DRX cycle: 1. The DRX deactivation timer (drx-InactivityTimer) times out; 2. The terminal device receives a DRX command MAC CE (DRX Command MAC CE);

[0057] When any of the following conditions is met, the terminal device uses the long DRX cycle: 1. The short DRX cycle timer (Drx-shortCycleTimer) times out; 2. The terminal device receives a long DRX command MCA CE (long DRX command MAC CE).

[0058] Regardless of whether it is a long DRX cycle or a short DRX cycle, if one or more of the following situations occurs, the terminal device is in a DRX activation state (sometimes also called a DRX on state), and the time corresponding to the DRX activation state can be called the DRX activation time (active time).

[0059] Case 1: Any of the DRX duration timer, DRX deactivation timer, DRX downlink retransmission timer, DRX uplink retransmission timer, and random access contention resolution timer is running;

[0060] Case 2: The terminal device sends a scheduling request (SR) on the PUCCH and is pending.

[0061] Case 3: There is data in the HARQ buffer of the terminal device and the terminal device is waiting for an uplink grant (UL grant) for HARQ retransmission.

[0062] Case 4: The terminal device successfully receives a random access response (RAR) in response to a preamble that is not selected by the MAC entity, but does not receive a PDCCH indicating the initial transmission using the cell radio network temporary identifier (C-RNTI) of the MAC entity.

[0063] In a DRX cycle, except for the DRX activation time, the remaining time can be called DRX deactivation time (inactive time) or sleep time. During the sleep time, the terminal device is in a sleep state (sometimes also called a DRX off state).

[0064] Extended DRX (eDRX)

[0065] eDRX is a technology introduced in 3GPP Release 13. Compared to DRX, eDRX has a longer paging cycle, enabling terminal devices to achieve greater power savings. For example, when a terminal device is in RRC Idle or RRC Inactive state, the DRX cycle and paging cycle are the same, but eDRX has a longer paging cycle than DRX. While the eDRX mechanism can achieve greater power savings, it also results in longer data transmission latency (such as longer downlink data latency).

[0066] Figure 4 is a schematic diagram of the eDRX cycle. As shown in Figure 4, during the paging time window (PTW), a terminal device monitors the paging channel according to the DRX cycle to receive downlink data (or services). Outside the PTW, the terminal device is in a dormant state, does not monitor the paging channel, and cannot receive downlink data (or services).

[0067] Positioning in DRX mode

[0068] When the terminal device is in a dormant state, it can send aperiodic SRS or measure PRS for positioning. As a result, waking up the terminal device from the dormant state during positioning is a key component of power consumption during positioning.

[0069] According to current protocols, DRX mode and uplink and downlink positioning are designed independently. In other words, the positioning process in communication systems is not currently designed with energy conservation in mind. Designing DRX mode and positioning measurements independently can lead to power consumption issues. Therefore, how to coordinate DRX mode and positioning measurements is an urgent issue that needs to be addressed.

[0070] To address the above issues, embodiments of the present application consider reducing the time difference between positioning measurement and paging monitoring (paging listening) to reduce the number of sleep transitions of the terminal device, thereby reducing the power consumption of the terminal device. For example, embodiments of the present application can minimize the time between PRS measurement / SRS transmission and paging monitoring to reduce the number of sleep transitions and thus reduce the resulting power consumption.

[0071] As a possible implementation, in order to reduce the time difference between positioning measurement and paging monitoring, thereby reducing the number of sleep transitions of the terminal device, DRX and the reference signal used for positioning (the first signal mentioned below) can be aligned. In other words, the embodiments of the present application jointly consider the configuration of DRX and the reference signal used for positioning, and try to ensure that the transmission / measurement of the reference signal used for positioning occurs within the activation time of DRX, thereby reducing the number of sleep transitions of the terminal device.

[0072] There are multiple ways to align DRX with the reference signal used for positioning. As one implementation method, the reference signal used for positioning can be fixed so that the DRX is configured in the interval corresponding to the reference signal used for positioning. For example, the transmission / measurement period of the reference signal used for positioning can be fixed. During the DRX configuration process, the DRX period can be configured according to the transmission / measurement period of the reference signal used for positioning, so that the transmission / measurement of the reference signal used for positioning occurs within the activation time of the DRX. As another implementation method, the DRX can be fixed so that the reference signal used for positioning is configured in the interval corresponding to the DRX. For example, the configuration of the DRX period can be fixed. During the configuration process of the reference signal used for positioning, the transmission / measurement period of the reference signal used for positioning can be configured according to the DRX period, so that the transmission / measurement of the reference signal used for positioning occurs within the activation time of the DRX.

[0073] During the DRX configuration process, DRX parameters (such as the DRX cycle) are configured based on the requirements of power consumption and paging delay. For example, for the RRC idle state and / or the RRC inactive state, the terminal device needs to monitor the paging occasion (PO) of each DRX cycle. Therefore, the configuration of the DRX cycle needs to take into account the requirements of the paging delay. Alternatively, in order to further reduce the power consumption of the terminal device, eDRX can be configured for the terminal device, for example, by configuring eDRX through upper layer signaling or RRC signaling. From this perspective, the eDRX cycle cannot be significantly adjusted for positioning purposes. In addition, when the terminal device is in the RRC idle state and / or the RRC inactive state, the paging opportunity position is related to the terminal device's identifier (UE_ID), and the paging opportunity adjustment space is not large. In this way, the reference signal used for positioning is fixed, making it difficult or impossible to implement DRX configuration in the interval corresponding to the reference signal used for positioning.

[0074] Therefore, the embodiment of the present application considers fixing the DRX so that the configuration of the reference signal used for positioning is in the interval corresponding to the DRX. For example, considering the situation where the reference signal used for positioning is aligned with the DRX, the embodiment of the present application can adopt an on-demand configuration process to change the configuration of the reference signal used for positioning (such as adjusting the period and time domain offset of the reference signal used for positioning) so that the reference signal used for positioning is aligned with the DRX. Taking the reference signal used for positioning as PRS as an example, for the situation where the PRS is aligned with the fixed DRX, the on-demand PRS process can be adopted to change the PRS configuration (such as adjusting the PRS period and time domain offset) so that the PRS is aligned with the DRX.

[0075] The technical solutions of the embodiments of the present application are described in detail below.

[0076] Figure 5 is a schematic flow chart of a wireless communication method provided by an embodiment of the present application. The method shown in Figure 5 is described from the perspective of the interaction between a terminal device and a network device. For example, the terminal device and the network device may be the terminal device 120 and the network device 110 shown in Figure 1, respectively. The method shown in Figure 5 may include step S510, which is described below.

[0077] In step S510, the terminal device receives first configuration information. In some embodiments, the first configuration information may be sent by the network device to the terminal device. However, the embodiments of the present application are not limited thereto. In some embodiments, the first configuration information may also be sent by a positioning device (such as LMF).

[0078] The first configuration information may be used to configure the first signal, or in other words, the first configuration information may be used to determine configuration parameters of the first signal. The first signal is a signal used for positioning (or locating a terminal device). In some embodiments, the first signal may be a reference signal (or pilot signal), for example, a positioning reference signal or a positioning pilot signal.

[0079] It should be noted that the reference signal used for positioning may include one or more of the following: an uplink positioning reference signal, a downlink positioning reference signal, and a side positioning reference signal. The uplink positioning reference signal may include, for example, an SRS. The downlink positioning reference signal may include, for example, a DL PRS. The side positioning reference signal may include, for example, an SL PRS. The embodiment of the present application does not limit the specific type of the first signal, as long as it is a reference signal that can be used for positioning. For example, the first signal may be an SRS, such as a periodic SRS and / or an aperiodic SRS. For another example, the first signal may be a PRS, such as the first signal may be one or more of the following: a periodic PRS, an aperiodic PRS, and an on-demand PRS.

[0080] It should be understood that the PRS mentioned in the embodiments of the present application may refer to DL PRS and / or SL PRS, and the embodiments of the present application are not limited thereto. For example, the first signal being a PRS may mean that the first signal is a DL PRS or that the first signal is a SL PRS.

[0081] In an embodiment of the present application, the first configuration information is determined based on the DRX parameters (or DRX configuration) of the terminal device. In other words, the first configuration information is associated with the DRX of the terminal device, that is, the determination of the first configuration information is related to the DRX of the terminal device. In an embodiment of the present application, the DRX parameters of the terminal device are taken into consideration when configuring the first signal, which helps to avoid the terminal device waking up from a sleep state to send the first signal, can reduce the number of sleep transitions of the terminal device, and thus help reduce the power consumption of the terminal device.

[0082] The embodiments of the present application do not limit the specific content of the first configuration information; the first configuration information may be any information used to configure the first signal. For example, the first configuration information may include one or more of the following parameters: parameters used to configure the time domain of the first signal; parameters used to configure the frequency domain of the first signal; parameters used to configure the code domain of the first signal; parameters used to configure the spatial domain of the first signal, etc.

[0083] Taking into account that in the embodiment of the present application, aligning the first signal with DRX mainly involves alignment in the time domain, the first configuration information is used to configure time domain related parameters of the first signal as an example to introduce the first configuration information in more detail.

[0084] In some embodiments, when the first configuration information is used to configure time domain related parameters of the first signal, the first configuration information can be used to configure one or more of the following parameters: the transmission / measurement period of the first signal, the transmission position of the first signal, and the transmission window of the first signal.

[0085] The transmission / measurement period of the first signal may be used to indicate a period for sending / measuring the first signal. Taking the first signal as an on-demand PRS as an example, the transmission / measurement period of the first signal may refer to the period of the on-demand PRS. Taking the first signal as an uplink positioning reference signal as an example, the transmission / measurement period of the first signal may refer to the period for sending the first signal (e.g., SRS); taking the first signal as a downlink positioning reference signal as an example, the transmission / measurement period of the first signal may refer to the period for measuring the first signal (e.g., DL PRS).

[0086] The transmission position of the first signal may refer to the time domain transmission position of the first signal. For example, the transmission position of the first signal may be used to indicate the time when the first signal is transmitted or the time when the first signal is measured. For example, taking the first signal as an uplink positioning reference signal as an example, the transmission position of the first signal may refer to the time when the first signal (such as an SRS) is transmitted. Alternatively, taking the first signal as a downlink reference signal as an example, the transmission position of the first signal may refer to the time when the first signal (such as a DL PRS) is measured.

[0087] In some embodiments, the transmission position of the first signal may be indicated by specific parameters. For example, the transmission position of the first signal may be indicated by the starting position (starting time) and duration of the first signal. For example, the transmission position of the first signal may refer to the number of time domain symbols in the time slot from which the first signal starts to be transmitted, and the number of time domain symbols in the time slot that the first signal occupies.

[0088] In some embodiments, the transmission position of the first signal can be indicated by a relative value, for example, by a relative value configured relative to a DRX parameter. As an example, the transmission position of the first signal can be indicated by a time domain offset of the first signal, which can be determined based on the DRX parameter. Exemplarily, the time domain offset of the first signal is 3 time domain symbols from the DRX activation moment (the starting moment of entering the DRX wake-up state), then the terminal device can determine the moment of sending / measuring the first signal as the moment corresponding to 3 time domain symbols from the DRX activation moment.

[0089] The transmission window of the first signal refers to a window configured for the first signal. The first signal can be sent within the window, and the first signal is not sent outside the configured window.

[0090] In some embodiments, the first signal is sent periodically within the transmission window of the first signal. In some embodiments, the period of sending the first signal within the transmission window of the first signal may also be configured according to the first configuration information.

[0091] In some embodiments, the transmission window of the first signal may be configured periodically. In other words, the transmission window of the first signal may be configured periodically.

[0092] In some embodiments, if the transmission window of the first signal is periodically configured and the first signal is periodically sent within the transmission window of the first signal, then the first configuration information can be used to configure two period values, one is the period of the transmission window of the first signal, and the other is the period of sending the first signal within the transmission window of the first signal.

[0093] In some embodiments, the first configuration information can be used to configure the number of transmissions for the transmission window of the first signal, so that the terminal device knows that the first signal needs to be sent within several transmission windows or the first signal needs to be measured within several transmission windows.

[0094] In some embodiments, the period of the transmission window of the first signal is different from the period of sending the first signal within the transmission window of the first signal. For example, the period of the transmission window of the first signal can be greater than the period of sending the first signal within the transmission window of the first signal. In this way, the first signal can be sent multiple times within the transmission window of the first signal, which is beneficial for reducing positioning latency or improving positioning accuracy.

[0095] For ease of understanding, an example of a transmission window for a first signal is provided below in conjunction with FIG6 . FIG6 is provided for the example of a PRS as the first signal. As shown in FIG6 , within a period (period length L1) of the PRS transmission window, the PRS is periodically transmitted within the PRS transmission window; however, outside the PRS transmission window, the PRS is not transmitted. Furthermore, in the example of FIG6 , the period (period length L2) during which the PRS is transmitted within the PRS transmission window is less than the period of the PRS transmission window.

[0096] In some embodiments, parameters related to the transmission window of the first signal may be indicated by specific parameters, such as the period of the transmission window of the first signal and the period of sending the first signal within the transmission window of the first signal.

[0097] In some embodiments, parameters related to the transmission window of the first signal may be indicated using relative values. For example, the period of the transmission window of the first signal, the period for sending the first signal within the transmission window of the first signal, etc. may be configured as relative values ​​using DRX parameters. As an example, the period of the transmission window of the first signal may be indicated using an offset relative to the DRX cycle. As another example, the period for sending the first signal within the transmission window of the first signal may be indicated using an offset relative to the DRX cycle.

[0098] In some embodiments, when the relevant parameters of the transmission window of the first signal are indicated using relative values, the offset of the period for sending the first signal within the transmission window of the first signal may be different from the offset of the period of the transmission window of the first signal. That is, the transmission window of the first signal and the first signal transmitted within the transmission window of the first signal may use different offsets. For example, the offset of the period for sending the first signal within the transmission window of the first signal and the offset of the period of the transmission window of the first signal are both offsets relative to the DRX cycle, and the offsets of the two relative to the DRX cycle are different.

[0099] In an embodiment of the present application, the first signal is a reference signal for positioning. In some embodiments, in addition to configuring the first signal, the first configuration information may also configure other parameters related to positioning measurement. For example, in addition to configuring time domain-related parameters of the first signal, the first configuration information may also configure one or more of the following parameters: positioning measurement parameters of the terminal device, and parameters related to the positioning measurement gap of the terminal device.

[0100] The embodiments of the present application do not specifically limit the positioning measurement parameters of the terminal device, as long as they are parameters related to the positioning measurement of the terminal device. For example, the positioning measurement parameters of the terminal device may include relevant parameters of the measurement method adopted by the terminal device, such as DL-AoA measurement parameters, DL-AoD measurement parameters, etc.; the positioning measurement parameters of the terminal device may include relevant parameters of the measurement quantity used by the terminal device for positioning measurement, such as reference signal received power, reference signal time difference between different cells, relative arrival time of reference signals received by the terminal device, arrival angle difference of reference signals received by the terminal device, etc.

[0101] The embodiments of the present application do not specifically limit the parameters related to the positioning measurement gap of a terminal device, as long as they can be used to determine the positioning measurement gap. For example, the parameters related to the positioning measurement gap of a terminal device may include the positioning measurement gap of the terminal device, the starting offset of the positioning measurement gap, the repetition period of the positioning measurement gap, etc.

[0102] The embodiments of the present application do not specifically limit the content of the DRX parameters (DRX configuration). The DRX parameters may be any parameters related to DRX of the terminal device. For example, the DRX parameters may include one or more of the following parameters: DRX-related time domain parameters, DRX-related frequency domain parameters, DRX-related code domain parameters, DRX-related spatial domain parameters, etc.

[0103] Taking into account that in the embodiment of the present application, aligning the first signal with the DRX mainly involves alignment in the time domain, the following takes the determination of the first configuration information mainly related to the time domain parameters of the DRX as an example to exemplify the DRX parameters.

[0104] The embodiments of the present application do not limit the time domain parameters of DRX. Exemplarily, DRX parameters may include the DRX cycle, DRX activation time (DRX wake-up time), DRX duration timer length, DRX deactivation timer length, short DRX cycle timer length, DRX downlink retransmission timer length, etc.

[0105] Based on the above introduction to the content of the first configuration information and the DRX parameters (or DRX configuration), the following is an exemplary introduction to how the first configuration information is determined according to the DRX parameters.

[0106] In some embodiments, the first configuration information may be related to the RRC state of the terminal device. In other words, the first configuration information may be configured according to the RRC state of the terminal device. That is, in embodiments of the present application, different first configuration information may be configured for the terminal device according to different RRC states. The RRC state of the terminal device may include one or more of the following RRC states: RRC connected state, RRC idle state, and RRC inactive state.

[0107] In some embodiments, the transmission / measurement period of the first signal may be configured according to the RRC state of the terminal device. For example, when the terminal device is in the RRC connected state, the sleep time of the terminal device is shorter, and therefore, the transmission / measurement period of the first signal may be configured to be shorter; when the terminal device is in the RRC idle state and / or the RRC inactive state, the sleep time of the terminal device is longer, and therefore, the transmission / measurement period of the first signal may be configured to be longer.

[0108] In some embodiments, the transmission / measurement period of the first signal corresponds to the DRX period of the terminal device. That is, the transmission / measurement period of the first signal is configured according to the DRX period of the terminal device. For example, the transmission / measurement period of the first signal may be the same as and correspond to the DRX period of the terminal device (or, the transmission / measurement period of the first signal may be synchronized with the DRX period of the terminal device). As an example, the transmission / measurement period of the first signal may include a time for transmitting / measuring the first signal and a time for not transmitting / measuring the first signal, wherein the time for transmitting / measuring the first signal may correspond to the DRX activation time, and the time for not transmitting / measuring the first signal may correspond to the DRX sleep time.

[0109] In some embodiments, the time for transmitting / measuring the first signal corresponds to the DRX activation time, which may mean that the time for transmitting / measuring the first signal is the same as the DRX activation time; the time for not transmitting / measuring the first signal corresponds to the DRX sleep time, which may mean that the time for not transmitting / measuring the first signal is the same as the DRX sleep time.

[0110] In some embodiments, the correspondence between the time of transmitting / measuring the first signal and the DRX activation time may mean that the time of transmitting / measuring the first signal is within the range of the DRX activation time.

[0111] In some embodiments, the transmission / measurement period of the first signal is configured according to the RRC state of the terminal device, and the transmission / measurement period of the first signal corresponds to the DRX period of the terminal device. In this way, the transmission / measurement of the first signal is consistent with the DRX period of the terminal device, which is conducive to reducing the number of wake-up times of the terminal device.

[0112] In some embodiments, the transmission / measurement period of the first signal corresponding to the terminal device when it is in the RRC connected state is shorter than the transmission / measurement period of the first signal corresponding to the terminal device when it is in the RRC idle state / RRC inactive state.

[0113] In some embodiments, the synchronization of the transmission / measurement period of the first signal with the DRX cycle is instructed by the network device. In some embodiments, the synchronization of the transmission / measurement period of the first signal with the DRX cycle is predefined by a protocol.

[0114] In some embodiments, the transmission position of the first signal is configured based on the RRC state of the terminal device. For example, when the terminal device is in different RRC states, the configured transmission position of the first signal may be different. As an example, when the terminal device is in an RRC connected state, the configured transmission position of the first signal is a first position; when the terminal device is in an RRC idle state and / or an inactive state, the configured transmission position of the first signal is a second position, and the first position and the second position may be different.

[0115] In some embodiments, the transmission position (time domain position) of the first signal corresponds to the DRX cycle of the terminal device. In other words, the transmission position of the first signal is configured according to the DRX cycle of the terminal device. For example, the transmission position of the first signal can be configured within the DRX activation time.

[0116] That is to say, in some embodiments, the network device may configure different parameters of the first signal for terminal devices in different RRC states (that is, the values ​​of the parameters of the first configuration information may be different). For example, the transmission / measurement period of the first signal configured for terminal devices in different RRC states mentioned above may be different, the transmission position of the configured first signal may be different, etc. For ease of understanding, the following example uses the different parameters such as the period and time domain offset of the first signal configured by the network device for terminal devices in different RRC states as an example to provide an exemplary introduction to this, wherein the first signal may be a PRS (for example, on-demand PRS, periodic PRS, etc.) or an SRS.

[0117] The network device can configure different parameters of the first signal for terminal devices in different RRC states, such as the period, time domain offset, etc. of the first signal. In some embodiments, these parameters such as period and time domain offset can be pre-configured for the terminal device. The terminal device can subsequently use different parameters to send / measure PRS according to different RRC states. As an example, the network device pre-configures the period and / or time domain offset in the RRC connected state, and the period and / or time domain offset in the RRC idle state / inactive state for the terminal device. After the terminal device receives the configuration information, when the terminal device is in the RRC connected state, the terminal device can send / measure the first signal according to the period and time domain offset of the RRC connected state; when the terminal device is in the RRC idle state / RRC inactive state, the terminal device can send / measure the first signal according to the period and time domain offset of the RRC idle state / RRC inactive state.

[0118] In some embodiments, the transmission window of the first signal is configured based on the DRX parameters of the terminal device. For example, the transmission window of the first signal may be a relative value configured based on the DRX parameters of the terminal device. However, embodiments of the present application are not limited thereto, and the transmission window of the first signal may also be a specific parameter value configured, where the specific parameter value is determined based on the DRX parameters of the terminal device.

[0119] In some embodiments, the transmission window of the first signal may correspond to the DRX activation time of the terminal device. For example, the transmission window of the first signal may be synchronized with (the same as) the DRX activation time of the terminal device; or the transmission window of the first signal may be configured within the DRX activation time of the terminal device.

[0120] In some embodiments, when the transmission window of the first signal is configured periodically, the period of the transmission window of the first signal may correspond to the DRX cycle (paging cycle) of the terminal device. For example, the period of the transmission window of the first signal may be synchronized with (the same as) the DRX cycle of the terminal device.

[0121] It should be understood that since the first signal (such as PRS) occupies more resources, the first signal transmitted in a continuous time may not be able to complete the positioning measurement of the terminal device, and the first signal needs to be sent / measured in the next time period after a period of time. Therefore, in some embodiments, it is necessary to configure multiple resources for the terminal device to send / measure the first signal at intervals. In this case, as an implementation method, a periodic first signal can be configured near the DRX activation time (such as within the DRX activation time), or the first signal is not sent / measured outside the DRX activation time. In this way, it is beneficial to ensure that the positioning measurement occurs as much as possible during the DRX activation time, reduce the number of wake-up times of the terminal device, and help reduce the power consumption of the terminal device.

[0122] In some embodiments, the first configuration information corresponding to the terminal device when it is in the RRC idle state is the same as the first configuration information corresponding to the terminal device when it is in the RRC inactive state. For example, for the transmission / measurement period of the first signal, the configuration of the transmission / measurement period of the first signal is the same when the terminal device is in the RRC idle state and when it is in the RRC inactive state. Alternatively, for the transmission position (e.g., time domain offset) of the first signal, the configuration of the transmission position of the first signal is the same when the terminal device is in the RRC idle state and when it is in the RRC inactive state.

[0123] In some embodiments, the first configuration information corresponding to the terminal device when it is in the RRC idle state may be at least partially different from the first configuration information corresponding to the terminal device when it is in the RRC inactive state. As an example, for the transmission / measurement period of the first signal and the transmission position of the first signal (e.g., time domain offset), the configuration of the transmission / measurement period of the first signal and the configuration of the transmission position of the first signal are different when the terminal device is in the RRC idle state and when it is in the RRC inactive state. As another example, for the transmission / measurement period of the first signal and the transmission position of the first signal (e.g., time domain offset), the configuration of the transmission / measurement period of the first signal may be the same, and the configuration of the transmission position of the first signal may be different when the terminal device is in the RRC idle state and when it is in the RRC inactive state; or, the configuration of the transmission / measurement period of the first signal may be different, and the configuration of the transmission position of the first signal may be the same when the terminal device is in the RRC idle state and when it is in the RRC inactive state.

[0124] In some embodiments, the terminal device may determine whether the first configuration information is related to the DRX parameter according to the instruction of the network device, or in other words, the terminal device may determine whether the first configuration information is determined according to the DRX parameter according to the instruction of the network device. This is described below with reference to FIG7 .

[0125] FIG7 is a flow chart of a wireless communication method according to another embodiment of the present application. The method shown in FIG7 may include step S710 and step S720.

[0126] In step S710, the terminal device receives first indication information, where the first indication information is used by the terminal device to determine whether the first configuration information is related to (concerned with) the DRX parameter.

[0127] In some embodiments, the first indication information can be used to indicate one or more of the following information: whether the first signal is determined according to the DRX parameters of the terminal device; whether the positioning measurement of the terminal device is determined according to the DRX parameters of the terminal device; whether the measurement gap used by the terminal device for positioning measurement is determined according to the DRX parameters of the terminal device, etc.

[0128] In some embodiments, the first indication information may be sent by the network device to the terminal device.

[0129] The terminal device can learn whether the first configuration information is related to the DRX parameters through the first indication information, which is beneficial for the terminal device to determine the first configuration information based on the DRX parameters.

[0130] In step S720, the terminal device receives first configuration information. The first configuration information is used to configure a first signal, which is a reference signal used for positioning.

[0131] For the relevant introduction of step S720, please refer to the introduction of step S510 above, and for the sake of brevity, it will not be repeated here.

[0132] The embodiment of the present application does not limit the execution order of step S710 and step S720. For example, step S710 can be executed before or after step S720, or can be executed simultaneously with step S720.

[0133] The embodiment of the present application does not limit the bearer of the first configuration information. The bearer of the first configuration information is introduced as an example below.

[0134] In some embodiments, the first configuration information may be carried in higher-layer signaling (e.g., RRC-related signaling). In some embodiments, the first configuration information may be carried in system information. In some embodiments, the first configuration information may be carried in a non-access stratum (NAS) message. In some embodiments, the first configuration information may be carried in interactive signaling related to positioning measurements.

[0135] Exemplarily, the first configuration information can be carried in one or more of the following: a system information block (SIB), an RRC release message received when the terminal device enters an RRC inactive state; a NAS message, positioning assistance information received when the terminal device performs positioning measurement, an RRC release message received when the terminal device performs positioning measurement, etc.

[0136] In some embodiments, the first configuration information and the DRX parameters of the terminal device may be carried in the same signaling. For example, the first configuration information is sent in signaling that carries the DRX parameters (DRX configuration). Exemplarily, the first configuration information and the DRX parameters may be carried in a system information block, or the first configuration information and the DRX parameters may be carried in an RRC release message, etc.

[0137] The embodiment of the present application does not limit the SIB that carries the first configuration information. For example, the first configuration information can be carried in SIB1, or the first configuration information can be carried in other SIBs other than SIB1.

[0138] In some embodiments, the first configuration information and / or the DRX configuration may be carried on a paging control channel (PCCH) in SIB 1. In some embodiments, this carrying method may be applicable when the terminal device is in an RRC idle state or an RRC inactive state.

[0139] In some embodiments, the first configuration information may be carried in an RRC release message received when the terminal device enters the RRC inactive state. For example, when the terminal device enters the RRC inactive state, the first configuration information may be carried in a PCCH configuration in the RRC release message. In some embodiments, this carrying method may be applicable when the terminal device is in the RRC inactive state.

[0140] In some embodiments, before the terminal device enters the RRC inactive state, the network device may send a DRX configuration to the terminal device via an RRC release message and notify the terminal device of the first configuration information (for example, the first configuration information corresponding to the terminal device in different RRC states).

[0141] In some embodiments, the first configuration information may be carried in a NAS message. For example, when the terminal device is in an RRC connected state, it may receive a NAS message in an RRC idle state and / or an RRC inactive state to determine the first configuration information through the NAS message.

[0142] In some embodiments, when the terminal device is in an RRC connected state, the network device may send a DRX configuration to the terminal device via a NAS message or SIB (such as SIB1). When configuring DRX via a NAS message, the network device may notify the terminal device of the first configuration information (for example, the first configuration information corresponding to the terminal device in different RRC states). As an example, when configuring DRX via a NAS message, the network device may notify the offset of the transmission position of the first signal relative to a certain DRX position (such as the time set by the DRX duration timer) in different RRC states. As another example, when configuring DRX via a NAS message, the network device may notify the transmission / measurement period of the first signal in different RRC states, etc.

[0143] In some embodiments, the first configuration information and / or DRX configuration carried in the RRC release message and NAS message received when the terminal device enters the RRC inactive state is a terminal device-specific configuration method, while the first configuration information and / or DRX configuration carried in the SIB (such as SIB1) is applicable to all terminal devices in the entire cell, and may not be suitable for changing for energy saving of a single terminal device.

[0144] In some embodiments, the first configuration information can be carried in interactive signaling related to positioning measurement. Figure 8 shows a schematic diagram of the positioning measurement process of a terminal device in the RRC idle state. In an embodiment of the present application, the first configuration information can be carried in positioning assistance information (such as step S830 in Figure 8); or, the first configuration information can be carried in an RRC release message (such as step S860 in Figure 8). However, the embodiment of the present application is not limited to this. The first configuration information can also be carried in other signaling related to positioning measurement, such as interactive signaling newly added during the positioning measurement process, and the newly added interactive signaling is used to carry the first configuration information, etc.

[0145] For ease of understanding, several examples are given below. The following examples are introduced using the first signal being a PRS as an example. It should be understood that the examples are not intended to limit the technical solutions of the present application.

[0146] It should be noted that the following examples can be used in any combination. For example, Example 1 and Example 2 can be combined, Example 1 and Example 3 can be combined, Example 2 and Example 4 can be combined, Example 1, Example 2 and Example 3 can be combined, etc.

[0147] Example 1: Configuring the PRS period based on the RRC state of the terminal device

[0148] When the terminal device is in the RRC connected state, the sleep time of the terminal device is shorter, so the on-demand PRS period is shorter. When the terminal device is in the RRC idle state and / or the RRC inactive state, the sleep time of the PRS is longer. Therefore, for the terminal device in the RRC idle state and / or the RRC inactive state, the PRS period is longer.

[0149] The network device can configure different PRS parameters, such as period or time domain offset, for terminal devices in different RRC states. These PRS parameters can be pre-configured for the terminal device, and the terminal device can subsequently use different PRS parameters to send / measure PRS according to different RRC states. For example, the network device pre-configures the period in the RRC connected state and the period in the RRC idle state / RRC inactive state for the terminal device. The terminal device receives this information. When the terminal device is in the RRC connected state, the terminal device sends / measures PRS according to the period and time domain offset of the RRC connected state. When the terminal device is in the RRC idle state / RRC inactive state, the terminal device sends / measures PRS according to the period and time domain offset of the RRC idle state / RRC inactive state.

[0150] In some embodiments, for the RRC idle state and the RRC inactive state, the network device may configure different PRS parameters for the terminal device, for example, the configured period and time domain offset values ​​are different.

[0151] In some embodiments, for the RRC idle state and the RRC inactive state, the PRS parameters configured by the network device for the terminal device may be partially the same and partially different. For example, for the RRC idle state and the RRC inactive state, the network device configures the same parameters (such as the time domain offset value) and different parameters (such as the period) for the terminal device.

[0152] Example 2: Configuring the periodic window for PRS transmission based on DRX parameters

[0153] The periodic window for PRS transmission configured according to the DRX parameters may be a specific parameter value, or a relative value configured according to the DRX parameters (relative value relative to a certain DRX parameter).

[0154] In some embodiments, because PRSs occupy a lot of resources, continuous PRS transmission at a time interval cannot complete positioning measurements. After a period of time, PRS measurements need to be performed in the next time interval. To achieve this, multiple PRS resources need to be configured at intervals. In some embodiments, periodic PRSs can be configured near the DRX activation time, and PRS transmission is not performed outside of the DRX activation time. For information on the configuration of the periodic window for PRS transmission, please refer to the description of Figure 6 above.

[0155] In some embodiments, the configuration of the PRS requires two periodicity values: for example, one is the period of the PRS transmission window, and the other is the period of PRS transmission within the window; or, one is the period within the PPW, and the other is the period of PRS transmission outside the PPW, or, one is the period within the PPW, and the other is the period of PRS transmission outside the PPW.

[0156] In some embodiments, the number of transmissions may be configured for a PRS transmission window, ie, the terminal device measures the PRSs of several windows.

[0157] In some embodiments, the window for PRS transmission and the transmission of PRS within the window may use different time domain offsets.

[0158] Example 3: Configuration signaling, configuring PRS in different states or PRS transmission window according to DRX configuration

[0159] Terminal devices can use DRX to reduce power consumption in RRC idle, RRC inactive, and RRC connected states. In RRC idle, RRC inactive, and RRC connected states, there are three ways for the network device to configure DRX for the terminal device:

[0160] Method 1: Use the PCCH configuration in SIB1, applicable to RRC idle state and RRC inactive state.

[0161] Method 2: Utilize the PCCH configuration in the RRC release message when the terminal device enters the RRC inactive state, which is applicable to the RRC inactive state.

[0162] Method 3: Utilize the NAS message received in the RRC idle state and / or RRC inactive state when the terminal device is in the RRC connected state.

[0163] It should be understood that the DRX configuration carried in the NAS message and the RRC release message is a terminal device-specific DRX configuration method. For the configuration in SIB1, since it applies to all terminal devices in the cell, it is not suitable to change it for energy saving of a single terminal device.

[0164] In some embodiments, the network device may send the first configuration information (PRS parameters) to the terminal device in the following manner.

[0165] Method 1: When the terminal device is in the RRC connected state, the DRX configuration is sent to the terminal device through a NAS message or SIB1; when DRX is configured through a NAS message, the terminal device can be notified of PRS parameters in the RRC idle state and / or RRC inactive state, and the RRC connected state, such as the offset of the PRS relative to a certain DRX position (such as the time set by the DRX duration timer).

[0166] Method 2: Before the terminal device enters the RRC inactive state, the DRX configuration is sent to the terminal device through the RRC release message to notify the terminal device of the PRS parameters in the RRC idle state and / or RRC inactive state and RRC connected state.

[0167] Example 4: Configuring signaling during positioning

[0168] Referring again to FIG8 , the network device may notify the terminal device of PRS parameters for different RRC states when performing LPP assisted data transmission (step S830 ). Alternatively, the network device may notify the terminal device of PRS parameters for different RRC states when sending an RRC release message (step S860 ).

[0169] The method embodiment of the present application is described in detail above in conjunction with Figures 1 to 8 . The device embodiment of the present application is described in detail below in conjunction with Figures 9 to 11 . It should be understood that the description of the method embodiment corresponds to the description of the device embodiment. Therefore, for portions not described in detail, reference can be made to the above method embodiment.

[0170] FIG9 is a schematic diagram of the structure of a terminal device according to an embodiment of the present application. The terminal device 900 shown in FIG9 may include a first receiving module 910 .

[0171] The first receiving module 910 can be used to receive first configuration information, where the first configuration information is used to configure a first signal, which is a reference signal for positioning; wherein the first configuration information is determined based on the DRX parameters of the terminal device.

[0172] Optionally, the first configuration information is used to configure one or more of the following parameters: the transmission / measurement period of the first signal; the transmission position of the first signal; the transmission window of the first signal; the positioning measurement parameters of the terminal device; and the parameters of the positioning measurement gap of the terminal device.

[0173] Optionally, at least one of the transmission / measurement period of the first signal and the transmission position of the first signal is configured according to the RRC state of the terminal device, and the transmission / measurement period of the first signal and / or the transmission position of the first signal corresponds to the DRX period of the terminal device.

[0174] Optionally, the transmission / measurement period of the first signal corresponding to when the terminal device is in the RRC connected state is shorter than the transmission / measurement period of the first signal corresponding to when the terminal device is in the RRC idle state and / or RRC inactive state.

[0175] Optionally, the transmission position of the first signal is indicated by a time domain offset of the first signal, and the time domain offset of the first signal is determined according to a DRX parameter of the terminal device.

[0176] Optionally, the transmission window of the first signal is a relative value configured according to the DRX parameters of the terminal device.

[0177] Optionally, the transmission window of the first signal is configured within the DRX activation time of the terminal device.

[0178] Optionally, within a transmission window of the first signal, the first signal is sent periodically.

[0179] Optionally, an offset of a period of sending the first signal within a transmission window of the first signal is different from an offset of a period of the transmission window of the first signal.

[0180] Optionally, the first configuration information is related to the RRC state of the terminal device, wherein the RRC state of the terminal device includes at least one of the following: RRC connected state, RRC idle state and RRC inactive state.

[0181] Optionally, the first configuration information corresponding to the terminal device when it is in the RRC idle state is the same as the first configuration information corresponding to the terminal device when it is in the RRC inactive state; or the first configuration information corresponding to the terminal device when it is in the RRC idle state is at least partially different from the first configuration information corresponding to the terminal device when it is in the RRC inactive state.
