Abstract
Description
Communication method, device and storage medium
[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on October 31, 2023, with application number 202311439135.3 and invention name “Communication Method, Device and Storage Medium”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the field of communication technology, and in particular to a communication method, device, and storage medium. Background Art
[0003] Access network equipment can configure standard terminals to transmit a broadband sounding reference signal (SRS) for positioning. The accuracy of the positioning measurement is determined by the SRS bandwidth. The larger the bandwidth, the higher the measurement accuracy, and the more accurate the terminal's position is.
[0004] Compared to standard terminals, a reduced-capability terminal (redcap UE) is a simplified terminal with reduced complexity. Based on the maximum channel bandwidth that a terminal must support, the maximum bandwidth for a single SRS transmission within frequency range 1 (FR1) is 20 MHz. To achieve the same measurement accuracy as a 100 MHz bandwidth SRS, a redcap UE must transmit the SRS multiple times using frequency hopping. This ensures that the frequency hopping transmission of a narrowband SRS is equivalent to, or similar to, the actual transmission of a wideband SRS by the terminal.
[0005] A reduced-capability terminal requires a certain amount of transition time when switching from the bandwidth location corresponding to one hop to the bandwidth location corresponding to another hop in the frequency domain to transmit SRS. The location of the first or last hop is outside the terminal's initial bandwidth part (BWP) or activated BWP, and the transition time for the first or last hop may be longer than that between the two intermediate hops. The initial or activated BWP is used to transmit / receive other channels or signals. When the time interval between each two hops of the frequency-hopping SRS is relatively long, the terminal needs to switch back and forth between the initial BWP or activated BWP and the frequency-hopping SRS resource location, resulting in higher terminal power consumption.
[0006] In view of this, how to reduce the power consumption of the terminal when sending the frequency hopping SRS is a problem that needs to be solved.
[0007] Summary of the Invention
[0008] The present application provides a communication method, device, and storage medium to reduce power consumption when a terminal sends a signal.
[0009] In a first aspect, a communication method is provided, wherein the method is implemented by an access network device, or a chip or circuit used for the access network device.
[0010] The method includes: the access network device sends resource configuration and / or scheduling information of a first signal to the terminal, the resource configuration and / or scheduling information is used to configure and / or schedule multiple resources of the first signal, wherein the time domain positions of the multiple resources do not overlap, and the frequency domain positions of the multiple resources partially overlap or do not overlap at all; and the access network device receives the first signal from the terminal at the position of the multiple resources within a first time period; wherein the terminal is not configured and / or scheduled to send a second signal within the first time period.
[0011] By adopting this method, the access network device configures and / or schedules multiple resources of the first signal, so that the terminal can send the first signal at the location of multiple resources within the first time period, and does not configure and / or schedule the terminal to send the second signal within the first time period. By clarifying the configuration and / or scheduling behavior of the access network device, the terminal does not need to switch back and forth between the initial BWP or activated BWP and the frequency-hopping SRS, or between multiple frequency-hopping SRS resources, thereby saving network and terminal power consumption; and when the first signal is used for uplink positioning, the access network device can receive a first signal that is equivalent to or similar to a broadband signal according to a frequency hopping pattern, thereby improving positioning accuracy.
[0012] With reference to the first aspect, in a possible implementation, the method further includes: sending configuration information of the first time period to the terminal.
[0013] In a second aspect, a communication method is provided, which is implemented by a terminal, or a chip or circuit used for a terminal.
[0014] The method includes: the terminal receives resource configuration and / or scheduling information of a first signal from an access network device, the resource configuration and / or scheduling information is used to configure and / or schedule multiple resources of the first signal, wherein the time domain positions of the multiple resources do not overlap, and the frequency domain positions of the multiple resources partially overlap or do not overlap at all; and the terminal sends the first signal at the multiple resource positions within a first time period; wherein the terminal does not expect the access network device to configure or schedule the terminal to send a second signal within the first time period.
[0015] By adopting this method, the terminal configures and / or schedules multiple resources of the first signal through the access network device. The terminal can send the first signal at the location of multiple resources within the first time period, and the terminal is not configured and / or scheduled to send the second signal within the first time period. By clarifying the configuration and / or scheduling behavior of the access network device, the terminal does not need to switch back and forth between the initial BWP or activated BWP and the frequency-hopping SRS, or between multiple frequency-hopping SRS resources, thereby saving network and terminal power consumption; and when the first signal is used for uplink positioning, the access network device can receive a first signal that is equivalent to or similar to a broadband signal according to a frequency hopping pattern, thereby improving positioning accuracy.
[0016] In combination with the second aspect, in a possible implementation, the method further includes: the terminal receiving configuration information of the first time period from the access network device.
[0017] In combination with the first aspect or the second aspect, in another possible implementation, the configuration information of the first time period includes at least one of the following: the starting system frame number of the first time period, the starting time slot, the starting symbol, the period of the first time period, and the duration of the first time period.
[0018] In combination with the first aspect or the second aspect, in another possible implementation, the starting position of the first time period is the starting position of the earliest first signal in the first signal in the time domain, and the ending position of the first time period is the ending position of the latest first signal in the first signal in the time domain.
[0019] In combination with the first aspect or the second aspect, in another possible implementation, the first signal is a positioning reference signal; and the second signal is a positioning reference signal or an uplink channel.
[0020] With this implementation, the terminal does not expect the access network device to configure, activate, or schedule other uplink channels or signals for transmission within the first time period, nor does it expect the first signal to overlap with other uplink channels or signals. Consequently, the access network device can receive an uplink Positioning Reference Signal (SRS) that is equivalent to or similar to a broadband signal according to an SRS frequency hopping pattern, thereby improving positioning accuracy.
[0021] In combination with the first aspect or the second aspect, in another possible implementation, the first signal and the second signal are positioning reference signals, and the first signal and the second signal are any one of the following: a periodic signal, a semi-continuous signal, or a non-periodic signal.
[0022] With this implementation, when both the first and second signals are periodic positioning reference signals, the terminal does not expect the access network device to configure more than one periodic frequency-hopping SRS resource for transmission within the first time period. That is, the access network device may configure only one periodic frequency-hopping SRS resource 1 for transmission within the first time period. Alternatively, the access network device may configure one periodic frequency-hopping SRS resource 1 for transmission within the first time period without configuring other periodic frequency-hopping SRS resources 2. Consequently, the access network device can receive and obtain an uplink positioning reference signal (SRS) that is equivalent to or similar to a broadband signal according to an SRS frequency-hopping pattern, thereby improving positioning accuracy.
[0023] For another example, when both the first signal and the second signal are non-periodic positioning reference signals, the terminal does not expect the access network device to trigger more than one non-periodic frequency-hopping SRS resource to be sent within the first time period. That is, the access network device can only trigger one non-periodic frequency-hopping SRS resource 1 to be sent within the first time period, or in other words, the access network device triggers one non-periodic frequency-hopping SRS resource 1 to be sent within the first time period without triggering other non-periodic frequency-hopping SRS resources 2. Thus, the access network device can receive and obtain an uplink positioning reference signal SRS that is equivalent to or similar to a broadband signal according to an SRS frequency-hopping pattern, thereby improving positioning accuracy. Alternatively, the terminal does not expect the access network device to trigger more than one non-periodic frequency-hopping SRS resource with overlapping portions.
[0024] For another example, when both the first signal and the second signal are semi-persistent positioning reference signals, the terminal does not expect the access network device to activate more than one semi-persistent frequency hopping SRS resource for transmission within the first time period. That is, the access network device can only activate one semi-persistent frequency hopping SRS resource 1 for transmission within the first time period, or in other words, the access network device activates one semi-persistent frequency hopping SRS resource 1 for transmission within the first time period without activating other semi-persistent frequency hopping SRS resources 2. Thus, the access network device can receive and obtain an uplink positioning reference signal SRS that is equivalent to or similar to a broadband signal according to an SRS frequency hopping pattern, thereby improving positioning accuracy. Alternatively, the terminal does not expect the access network device to activate more than one semi-persistent frequency hopping SRS resource with overlapping portions.
[0025] According to a third aspect, a communication method is provided, which is implemented by a terminal, or a chip or circuit for a terminal.
[0026] The method includes: the terminal receives resource configuration and / or scheduling information of a first signal from an access network device, and receives configuration or scheduling information of a second signal, wherein the resource configuration and / or scheduling information of the first signal is used to configure and / or schedule multiple resources of the first signal, the time domain positions of the multiple resources do not overlap, and the frequency domain positions of the multiple resources partially overlap or do not overlap at all, and the time domain position of at least one resource among the multiple resources of the first signal is no later than that of the second signal; and the terminal only sends the first signal within a first time period.
[0027] By adopting this method, the terminal itself clarifies the uplink sending behavior, reduces the constraints on the network side configuration or scheduling, clarifies the terminal behavior when certain configurations occur, and enables the network side and the terminal to have a consistent understanding of the terminal behavior.
[0028] In combination with the third aspect, in a possible implementation, the method further includes: the terminal does not send the second signal within the first time period.
[0029] With this implementation, after receiving the resource configuration and / or scheduling information for the first signal and the configuration or scheduling information for the second signal, the terminal only sends the first signal to the access network device during the first time period and does not send the second signal during the first time period. This ensures that the first signal can be fully transmitted or received across multiple resources.
[0030] In combination with the third aspect, in another possible implementation, the time domain position of at least one resource among the multiple resources of the first signal is no later than that of the second signal, and the first signal and the second signal are signals of the same type, and the type of the signal includes any one of the following: a periodic signal, a semi-continuous signal, or a non-periodic signal.
[0031] With this implementation, assuming both the first and second signals are periodic, and the access network device configures more than one periodic frequency-hopping SRS resource for transmission within the first time period, or more than one periodic frequency-hopping resource overlaps, the terminal only transmits the earliest periodic frequency-hopping SRS transmitted within the first time period and discards other periodic frequency-hopping SRSs with later transmission start times. This ensures that a complete periodic frequency-hopping SRS is transmitted, and eliminates the need to transmit other periodic frequency-hopping SRSs, thereby saving terminal power consumption.
[0032] Assuming that both the first signal and the second signal are aperiodic signals, and the access network device triggers more than one aperiodic signal to be sent within the first time period, or more than one aperiodic resource overlaps, the terminal only sends the earliest aperiodic signal sent within the first time period and discards other aperiodic signals with later start times. The network and the terminal have a consistent understanding of the terminal's behavior.
[0033] Assume that both the first signal and the second signal are semi-persistent signals. If the access network device activates more than one semi-persistent signal to be sent within the first time period, or if more than one semi-persistent signal resource overlaps, the terminal only sends the semi-persistent signal sent earliest within the first time period and discards other semi-persistent signals with later start times. The network and the terminal have a consistent understanding of the terminal's behavior.
[0034] In combination with the third aspect, in another possible implementation, the first signal is a non-periodic signal, and the second signal is a periodic signal or a semi-continuous signal.
[0035] With this implementation, if the access network device triggers an aperiodic signal to be sent within a first time period and also configures a periodic signal or activates a semi-persistent signal to be sent within the first time period, or if the aperiodic resources overlap with the periodic or semi-persistent resources, and the aperiodic signal has a higher priority or urgency than the periodic or semi-persistent signal, the terminal will only send the aperiodic signal within the first time period and discard the periodic or semi-persistent signal. The network and the terminal have a consistent understanding of this terminal's behavior.
[0036] In a fourth aspect, a communication method is provided, which is implemented by a terminal, or a chip or circuit used for a terminal.
[0037] The method includes: the terminal receives resource configuration and / or scheduling information of a first signal from an access network device, and receives configuration or scheduling information of a second signal, wherein the resource configuration and / or scheduling information of the first signal is used to configure and / or schedule multiple resources of the first signal, wherein the time domain positions of the multiple resources do not overlap, and the frequency domain positions of the multiple resources partially overlap or do not overlap at all, and the time domain position of at least one resource among the multiple resources of the first signal is not later than that of the second signal; and within a first time period, the terminal does not send the first signal, and only sends the second signal.
[0038] By adopting this method, the terminal itself clarifies the uplink sending behavior, reduces the constraints on the network side configuration or scheduling, clarifies the terminal behavior when certain configurations occur, and enables the network side and the terminal to have a consistent understanding of the terminal behavior.
[0039] In combination with the fourth aspect, in a possible implementation, the first signal is a periodic signal, and the second signal is a non-periodic signal or a semi-continuous signal.
[0040] With this implementation, the access network device configures a periodic signal to be sent within the first time period, and also configures resources for a non-periodic signal or a semi-persistent signal to be sent within the first time period; or, the resources for the non-periodic signal or the semi-persistent signal overlap with the resources for the periodic signal. Since the priority of the non-periodic signal or the semi-persistent signal is higher than that of the periodic signal, during the first time period, the terminal does not send the first signal (discards the first signal) and only sends the second signal. This ensures the timely transmission of high-priority signals. For example, if the non-periodic signal or the semi-persistent signal is an uplink positioning reference signal SRS, emergency positioning requirements are met.
[0041] In combination with the fourth aspect, in another possible implementation, the first signal is a semi-continuous signal, and the second signal is a non-periodic signal.
[0042] With this implementation, the access network device configures a semi-persistent signal and also configures resources for a non-periodic signal to be sent within the first time period; alternatively, the resources for the semi-persistent signal overlap with the resources for the periodic signal. Because the non-periodic signal has a higher priority than the semi-persistent signal, the terminal does not send the first signal (discards the first signal) and only sends the second signal within the first time period. This ensures the timely transmission of the high-priority signal. For example, if the non-periodic signal is an uplink positioning reference signal (SRS), emergency positioning requirements are met.
[0043] In combination with the third aspect or the fourth aspect, in another possible implementation, the starting position of the first time period is the starting position of the earliest first signal in the first signal in the time domain, and the ending position of the first time period is the ending position of the latest first signal in the first signal in the time domain.
[0044] In combination with the third aspect or the fourth aspect, in another possible implementation, the method further includes: the terminal receiving configuration information of the first time period from the access network device.
[0045] In combination with the third aspect or the fourth aspect, in another possible implementation, the configuration information of the first time period includes at least one of the following: the starting system frame number of the first time period, the starting time slot, the starting symbol, the period of the first time period, and the duration of the first time period.
[0046] In a fifth aspect, a communication device is provided for implementing the communication method in any one of the second, third, and fourth aspects or the second, third, and fourth aspects. The device may be a terminal, a module applied to a terminal (e.g., a processor, a chip, or a chip system), or a logical node, a logical module, or software that implements all or part of the terminal's functions.

The device may be an access network device, a module (such as a processor, chip, or chip system) applied to an access network device, or a logical node, logical module, or software capable of implementing all or part of the functions of the access network device.

[0081] The solution of this application is further described below with reference to the accompanying drawings.
[0082] Figure 1 shows a possible, non-limiting system diagram. As shown in Figure 1, communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one RAN node (e.g., 110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 1). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wiredly connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device that integrates core network logical functions and radio access network logical functions.
[0083] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 may also be a communication system that integrates two or more of the above systems.
[0084] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and facilitates wireless access for terminals. Multiple RAN nodes 110 in communication system 1000 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminal 120j accessing RAN 100 via network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functionality, and network elements 120a-120j can be understood as communication devices with terminal functionality.
[0085] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can be a macro base station (such as 110a in Figure 1 ), a micro base station or an indoor station (such as 110b in Figure 1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Alternatively, a RAN node can be a server, a wearable device, a vehicle, or an onboard device. For example, the access network device in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).
[0086] In another possible scenario, multiple RAN nodes assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).
[0087] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.
[0088] A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal may be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.
[0089] The communication between the access network device and the terminal device follows a certain protocol layer structure. The protocol layer may include a control plane protocol layer and a user plane protocol layer.

[0092] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.
[0093] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.
[0094] In the embodiments of the present application, a base station is also referred to as an access network device. The device used to implement the functions of the access network device can be the access network device; it can also be a device that can support the access network device in implementing the functions, such as a chip system, a hardware circuit, a software module, or a hardware circuit and a software module. The device can be installed in the access network device or used in conjunction with the access network device. In the embodiments of the present application, only the device used to implement the functions of the access network device is used as an example, and the embodiments of the present application are not limited to the solutions of the embodiments of the present application.
[0095] It can be understood that the present application can be applied between access network equipment and terminals.
[0096] It should be understood that the number and type of each device in the communication system shown in Figure 1 are for illustration only, and the present application is not limited to this. In actual applications, the communication system may also include more terminals, more access network devices, and other network elements, such as core network devices, and / or network elements for implementing artificial intelligence functions.
[0097] It is understandable that all or part of the functions implemented by one or more of the terminals, access network devices, core network devices, or network elements for implementing artificial intelligence functions can be virtualized, that is, implemented by one or more of the proprietary processors or general-purpose processors and the corresponding software modules. Among them, since the terminal and the access network device involve an interface for air interface transmission, the transceiver function of the interface can be implemented by hardware. Core network equipment, such as operation administration and maintenance (OAM) network elements, can be virtualized. Optionally, one or more functions of the virtualized terminal, access network device, core network device, or network elements for implementing artificial intelligence functions can be implemented by cloud devices, such as cloud devices in an over the top (OTT) system.
[0098] The following explains several terms involved in the embodiments of this application:
[0099] (1) Reduced capability terminals:
[0100] Compared to ordinary terminals, a reduced-capability terminal is a simplified terminal with reduced complexity. Based on the specified maximum channel bandwidth capabilities that must be supported by the terminal, within the FR1 frequency range (410MHz-7125MHz), the mandatory capability of a reduced-capability terminal is to support a maximum terminal channel bandwidth of 20MHz, while ordinary terminals must support a maximum terminal channel bandwidth of 100MHz. In the FR2 frequency range (24250MHz-52600MHz), the mandatory capability of a reduced-capability terminal is to support a maximum terminal channel bandwidth of 100MHz, while ordinary terminals must support a maximum terminal channel bandwidth of 400MHz.
[0101] (2) Frequency hopping transmission for positioning
[0102] For a 100MHz bandwidth carrier within the FR1 range, the access network equipment can configure ordinary terminals to send a broadband SRS (for example, 100MHz) for positioning. The access network equipment directly receives and measures the 100MHz bandwidth SRS signal through several transmission reception points (TRPs) deployed at different geographical locations. It obtains the time of arrival (ToA) from the terminal sending the SRS to the TRP receiving the SRS, and reports the ToA measurement value to the location management function (LMF), which ultimately calculates the terminal's position. This process is a method of uplink positioning based on the cellular network. The ToA measurement accuracy is determined by the SRS bandwidth. The larger the bandwidth, the higher the measurement accuracy, and the more accurate the terminal's position is ultimately determined.
[0103] For a reduced-capability terminal, the maximum bandwidth for a single SRS transmission is 20 MHz. To obtain measurement results with the same or similar accuracy as a 100 MHz bandwidth SRS, the reduced-capability terminal needs to transmit the SRS multiple times in a continuous frequency hopping manner, so that frequency hopping to transmit a narrowband SRS is equivalent to or similar to the terminal actually transmitting a wideband SRS, as shown in the SRS frequency hopping pattern in Figure 2. The receiving end receives and processes the frequency-hopped SRS and obtains measurement results equivalent to or similar to those of a 100 MHz bandwidth SRS.
[0104] The reduced-capability terminal obtains configuration information sent by the access network device, including the location of the starting physical resource block (PRB) in the frequency domain for the first hop in the time domain, the bandwidth of each hop, the number of resources overlapped in the frequency domain between two consecutive hops (such as the number of overlapping PRBs), the time slot offset and starting symbol of the first hop in the time domain, the time slot offset and starting symbol of each hop after the first hop, the number of consecutive symbols in each hop, and the total number of hops. This configuration information uniquely determines the frequency hopping SRS pattern, as shown in Figure 2. After obtaining this configuration information, the terminal transmits the SRS according to the frequency hopping pattern.
[0105] Figure 3 illustrates the switching time for frequency-hopping SRS transmission. When a reduced-capability terminal transmits SRS according to a frequency-hopping pattern, a switching time is required to switch from one hop's bandwidth location to another hop's bandwidth location in the frequency domain. Specifically, if the first or last hop is outside the terminal's initial or activated BWP, or if the subcarrier spacing, bandwidth, or cyclic prefix (CP) size differs between the first and last hops, the switching time (T0 in the figure) is longer than the switching time between the two intermediate hops. Possible values include {100us, 140us, 200us, 300us, 500us}, applicable to both FR1 and FR2. The longest possible switching time (T1 in the figure) between two consecutive intermediate hops includes {35us, 70us, 125us}. This value depends on the terminal's implemented capabilities.
[0106] Understandably, the configuration of terminals using frequency hopping to transmit SRS by access network equipment may not be limited to terminals with reduced capabilities. For standard terminals, the activated BWP may be configured to be smaller to reduce power consumption, and SRS can only be transmitted within the activated BWP. Therefore, the bandwidth available for SRS transmission is limited by the bandwidth of the activated BWP, making it impossible to achieve high-precision positioning by transmitting wideband SRS.
[0107] When a terminal is configured to transmit a positioning SRS using frequency hopping, the terminal transmits the SRS according to the above-described frequency hopping pattern. Furthermore, as shown in FIG4 , a schematic diagram of frequency hopping SRS transmission in a time-division duplex (TDD) system, the time slots used for downlink transmission and the time slots used for uplink transmission in the TDD system are staggered in the time domain (the figure is described using an uplink (UL): downlink (DL) ratio of 2:8 and a subcarrier spacing (SCS) of 30 kHz as an example). Given the flexibility of the access network device in configuring the frequency hopping pattern, it is possible that consecutive uplink time slots may not allow the terminal to continuously complete frequency hopping SRS transmission. The last hop must be transmitted within the uplink time slot of the next TDD cycle. Therefore, before completing the last hop, the terminal must receive a downlink channel or signal within the downlink time slot.
[0108] Alternatively, regardless of whether it is a TDD system or a frequency-division duplex (FDD) system, given the flexibility of the access network device in configuring the frequency hopping pattern, between every two hops, the access network device may schedule / configure the terminal to receive a downlink channel or signal, or schedule / configure the terminal to send an uplink channel or signal. Whether receiving a downlink or sending an uplink, the terminal requires time to switch from the resource location where the frequency-hopping SRS is sent to the resource location where the downlink or uplink is received, as shown in Figures 5A and 5B. If the time required to switch from the location where the SRS is sent to the location where the downlink or uplink is received, and then from the location where the downlink or uplink is received to the location where the SRS is sent on the next hop, is less than the time domain interval between the two hops, then the terminal can switch locations to receive a downlink or send an uplink without affecting the transmission of the frequency-hopping SRS.
[0109] When the time interval between two hops of the frequency hopping SRS is relatively long, the terminal needs to switch back and forth between the resource locations of the data activation BWP or the initial BWP and the frequency hopping SRS, resulting in high power consumption of the terminal.
[0110] To address the above problems, the present application provides a communication solution that clarifies the configuration and / or scheduling behavior of the access network device so that the terminal does not need to switch back and forth between the initial BWP or activated BWP and the frequency-hopping SRS, thereby saving network and terminal power consumption; or the terminal itself clarifies the uplink sending behavior to reduce its own power consumption.
[0111] The communication solution of this application can be used in various communication scenarios, such as uplink and downlink communication and uplink positioning. As shown in Figure 6, an uplink and downlink communication and positioning system architecture diagram provided by an embodiment of this application is provided. The terminal can perform uplink and downlink communication with its serving base station, and the terminal can also send uplink positioning reference signals (SRS) to neighboring base stations for uplink positioning.
[0112] As shown in Figure 7, a flow chart of a communication method provided in an embodiment of the present application is shown. Exemplarily, the method may include the following steps:
[0113] S701. An access network device sends resource configuration and / or scheduling information of a first signal to a terminal. Correspondingly, the terminal receives the resource configuration and / or scheduling information of the first signal.
[0114] In this embodiment, the access network device configures and / or schedules the terminal to send a first signal on multiple resources. Therefore, the access network device sends resource configuration and / or scheduling information of the first signal to the terminal. The resource configuration and / or scheduling information is used to configure and / or schedule multiple resources for the first signal. The time domain positions of the multiple resources do not overlap, and the frequency domain positions of the multiple resources partially overlap or do not overlap at all. Exemplarily, the first signal can be the SRS transmitted by the above-mentioned frequency hopping. The SRS is used for uplink positioning. Furthermore, the access network device can also configure an SRS pattern. The SRS can be periodic, aperiodic, or semi-continuous.
[0115] Exemplarily, the access network device may send resource configuration information of the first signal to the terminal through radio resource control (RRC) signaling or the like.
[0116] Exemplarily, the access network device may send resource scheduling information of the first signal to the terminal via downlink control information (DCI) or the like, to activate the configured resources of the first signal.
[0117] S702. The terminal sends a first signal to the access network device at multiple resource locations within a first time period. Correspondingly, the access network device receives the first signal from the terminal at multiple resource locations within the first time period.
[0118] After receiving the resource configuration and / or scheduling information of the first signal, the terminal, taking into account the need to meet positioning accuracy requirements, sends the first signal to the access network device at multiple resource locations within a first time period. This first time period can also be called a first time window.
[0119] The above-mentioned first time period can be pre-defined by the protocol, or pre-negotiated by the terminal and the access network device, or configured by the access network device. In this case, the method can further include the following steps: the access network device sends configuration information of the first time period to the terminal. Accordingly, the terminal receives the configuration information of the first time period. The configuration information of the first time period includes at least one of the following: the starting system frame number (SFN) of the first time period, the starting time slot, the starting symbol, the period of the first time period, and the duration of the first time period. Exemplarily, the configuration of the first time period can be periodic. The configured first time period is shown in Figure 8.
[0120] The starting position of the first time period is the starting position of the earliest first signal in the time domain, and the ending position of the first time period is the ending position of the latest first signal in the time domain.
[0121] Since the above-mentioned first time period and multiple resources of the first signal are configured to the terminal by the access network device, the access network device can configure a suitable first time period and multiple resources of the first signal, so that the terminal sends the first signal on multiple first resources within the first time period according to the configuration.
[0122] In order to avoid the terminal having to switch back and forth between the resource locations of the data activation BWP or the initial BWP and the frequency hopping SRS, resulting in high power consumption of the terminal, in this embodiment, the access network device does not configure and / or schedule the terminal to send the second signal within the first time period. That is, within the first time period, if there are multiple resources configured and / or scheduled for the first signal, the terminal only sends the first signal within the first time period and does not send other uplink channels or signals. It can be understood that if there is reception of a downlink channel (a media access control element (MAC CE) carried on a physical downlink shared channel (PDSCH)) as shown in Figure 9A or reception of a downlink signal (DCI carried on a physical downlink control channel (PDCCH)) as shown in Figure 9B within the first time period, it will not be affected, that is, the terminal can complete the reception of the downlink channel or signal within the first time period. However, the uplink channel or signal activated by the MAC CE or scheduled by the DCI cannot appear within the first time period. Alternatively, the uplink channel or signal activated by the MAC CE or scheduled by the DCI appears within a first time period, and the terminal does not send the uplink channel or signal within the first time period.
[0123] The terminal does not expect the access network device to configure redundant resources other than the multiple resources of the first signal to be sent within the first time period, that is, the access network device can only configure the multiple resources of the first signal to be sent within the first time period, or in other words, the access network device configures the multiple resources of the first signal to be sent within the first time period, but does not configure the multiple resources of the second signal to be sent within the first time period. Thus, the access network device can receive and obtain an uplink positioning reference signal SRS that is equivalent to or similar to a broadband signal according to an SRS frequency hopping pattern, which can improve positioning accuracy. For example, the access network device does not configure overlapping signal resources as shown in Figure 10A (multiple R1 signals and multiple R2 signals partially overlap in frequency domain position within the first time period), and the terminal does not expect the access network device to configure overlapping signal resources to be sent within the first time period. The access network device can configure non-overlapping signal resources as shown in Figure 10B (multiple R1 signals and multiple R2 signals do not overlap in frequency domain position within the first time period).
[0124] In one example, the first signal is a positioning reference signal, and the second signal is a positioning reference signal, wherein the first signal and the second signal are any of the following: a periodic signal, a semi-persistent signal, or an aperiodic signal.
[0125] For example, when both the first signal and the second signal are periodic positioning reference signals, the terminal does not expect the access network device to configure more than one periodic frequency-hopping SRS resource for transmission within the first time period. That is, the access network device may configure only one periodic frequency-hopping SRS resource 1 for transmission within the first time period. Alternatively, the access network device may configure one periodic frequency-hopping SRS resource 1 for transmission within the first time period, but may not configure other periodic frequency-hopping SRS resources 2 for transmission within the first time period. Thus, the access network device can receive and obtain an uplink positioning reference signal (SRS) that is equivalent to or similar to a broadband signal according to an SRS frequency-hopping pattern, thereby improving positioning accuracy.
[0126] For another example, when the first signal and the second signal are both non-periodic positioning reference signals, the terminal does not expect the access network device to trigger more than one non-periodic frequency hopping SRS resource to be sent within the first time period, that is, the access network device can only trigger one non-periodic frequency hopping SRS resource 1 to be sent within the first time period, or in other words, the access network device triggers one non-periodic frequency hopping SRS resource 1 to be sent within the first time period, but does not trigger other non-periodic frequency hopping SRS resources 2 to be sent within the first time period. Thus, the access network device can receive and obtain an uplink positioning reference signal SRS that is equivalent to or similar to a broadband signal according to an SRS frequency hopping pattern, thereby improving positioning accuracy. Alternatively, the terminal does not expect the access network device to trigger more than one overlapping non-periodic frequency hopping SRS resource to be sent within the first time period.
[0127] For another example, when both the first signal and the second signal are semi-continuous positioning reference signals, the terminal does not expect the access network device to activate more than one semi-continuous frequency hopping SRS resource to be sent within the first time period, that is, the access network device can only activate one semi-continuous frequency hopping SRS resource 1 to be sent within the first time period, or in other words, the access network device activates one semi-continuous frequency hopping SRS resource 1 to be sent within the first time period, and does not activate other semi-continuous frequency hopping SRS resources 2 to be sent within the first time period. Thus, the access network device can receive and obtain an uplink positioning reference signal SRS that is equivalent to or similar to a broadband signal according to an SRS frequency hopping pattern, thereby improving positioning accuracy. Alternatively, the terminal does not expect the access network device to activate more than one overlapping semi-continuous frequency hopping SRS resource to be sent within the first time period.
[0128] It can be understood that the second signal may be a frequency hopping signal like the first signal, or may not be a frequency hopping signal.
[0129] In another example, the first signal is a positioning reference signal, and the second signal is an uplink channel. The terminal does not expect the access network device to configure, activate or schedule other uplink channels or signals to be sent within the first time period, or does not expect the first signal to overlap with other uplink channels or signals within the first time period. Overlap means that there are other uplink channels or signals within the span of a complete frequency hopping SRS pattern. The second signal can be an uplink positioning reference signal SRS but without frequency hopping, or other SRS other than the uplink positioning reference signal SRS (for example, for beam management, channel measurement based on codebook or non-codebook downlink transmission, or channel measurement for antenna switching, etc.), or a physical uplink shared channel (PUSCH), or a physical uplink control channel (PUCCH), or an uplink physical random access channel (PRACH), or an uplink scheduling request (SR). For example, the access network device only configures one periodic frequency hopping SRS resource 1 for transmission in the first time period, or in other words, the access network device configures one periodic frequency hopping SRS resource 1 for transmission in the first time period, but does not configure, activate, or schedule other uplink channels or signals for transmission in the first time period, or the transmission in the first time period overlaps with other uplink channels or signals. For another example, the access network device may only activate one semi-persistent frequency hopping SRS resource 1 for transmission in the first time period, or in other words, the access network device activates one semi-persistent frequency hopping SRS resource 1 for transmission in the first time period, but does not configure, activate, or schedule other uplink channels or signals for transmission in the first time period, or the transmission in the first time period overlaps with other uplink channels or signals. For another example, the access network device may only activate one semi-persistent frequency hopping SRS resource 1 for transmission in the first time period, or in other words, the access network device activates one semi-persistent frequency hopping SRS resource 1 for transmission in the first time period, but does not configure, activate, or schedule other uplink channels or signals for transmission in the first time period, or the transmission in the first time period overlaps with other uplink channels or signals. Thus, the access network device can receive an uplink positioning reference signal (SRS) that is equivalent to or similar to a broadband signal according to an SRS frequency hopping pattern, thereby improving positioning accuracy. Alternatively, the terminal does not expect the access network device to configure, activate, or schedule more than one overlapping uplink channel or signal to be transmitted within the first time period.
[0130] According to a communication method provided by an embodiment of the present application, an access network device configures and / or schedules multiple resources of a first signal, so that a terminal can send a first signal at the location of multiple resources within a first time period, and does not configure and / or schedule the terminal to send a second signal within the first time period. By clarifying the configuration and / or scheduling behavior of the access network device, the terminal does not need to switch back and forth between an initial BWP or an activated BWP and a frequency-hopping SRS, or between multiple frequency-hopping SRS resources, thereby saving network and terminal power consumption; and when the first signal is used for uplink positioning, the access network device can receive a first signal that is equivalent to or similar to a broadband signal according to a frequency hopping pattern, thereby improving positioning accuracy.
[0131] The above embodiments describe that by clarifying the configuration and / or scheduling behavior of the access network device, the terminal does not need to switch back and forth between the initial BWP or activated BWP and the frequency-hopping SRS, or between multiple frequency-hopping SRS resources, thereby saving network and terminal power consumption.
[0132] The following embodiment will describe how the terminal explicitly performs uplink transmission to reduce its own power consumption.
[0133] As shown in Figure 11, it is a flowchart of another communication method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:
[0134] S1101. An access network device sends resource configuration and / or scheduling information of a first signal and configuration or scheduling information of a second signal to a terminal. Correspondingly, the terminal receives the resource configuration and / or scheduling information of the first signal and configuration or scheduling information of the second signal from the access network device.
[0135] In this embodiment, the access network device configures and / or schedules multiple resources for the first signal, and configures and / or schedules resources for the second signal. The access network device sends resource configuration and / or scheduling information for the first signal, as well as configuration or scheduling information for the second signal, to the terminal. That is, in addition to configuring multiple resources for the first signal, the access network device also configures resources for the second signal; or, the resources for the second signal overlap with at least one of the multiple resources for the first signal. "Configuration" can include sending configuration information via RRC signaling, for example, and "scheduling" can include scheduling via DCI, for example.
[0136] It is understandable that the resource configuration and / or scheduling information of the first signal and the configuration or scheduling information of the second signal can be located in the same message or in different messages. This embodiment does not limit the order in which the access network device sends the resource configuration and / or scheduling information of the first signal and the configuration or scheduling information of the second signal, nor does it limit the order in which the terminal receives the resource configuration and / or scheduling information of the first signal and the configuration or scheduling information of the second signal.
[0137] The resource configuration and / or scheduling information of the first signal is used to configure and / or schedule multiple resources for the first signal. The time domain locations of the multiple resources do not overlap, and the frequency domain locations of the multiple resources partially overlap or do not overlap at all. The first signal may be a frequency-hopping signal, such as an uplink Positioning Reference Signal (SRS) transmitted using frequency hopping. For the meaning of "overlap," refer to the above description.
[0138] In which, the time domain position of at least one resource among the multiple resources of the first signal is not later than that of the second signal. In other words, the time domain position of at least one resource among the multiple resources of the first signal is earlier than that of the second signal, or the time domain position of at least one resource among the multiple resources of the first signal is the same as the time domain position of the resources of the second signal.
[0139] In one example, the first signal and the second signal are signals of the same type. For example, the first signal is a periodic signal (e.g., an SRS transmitted in a frequency hopping manner), and the second signal is also a periodic signal; the first signal is a semi-persistent signal, and the second signal is also a semi-persistent signal; the first signal is an aperiodic signal, and the second signal is also an aperiodic signal.
[0140] In another example, the first signal is a non-periodic signal, and the second signal is a periodic signal or a semi-continuous signal.
[0141] S1102: The terminal sends a first signal only to the access network device within a first time period. Correspondingly, the access network device receives the first signal within the first time period.
[0142] After receiving the resource configuration and / or scheduling information for the first signal and the configuration or scheduling information for the second signal, the terminal transmits only the first signal to the access network device during the first time period and does not transmit the second signal during the first time period. This ensures the complete transmission or reception of the first signal across multiple resources. When the first signal is a frequency-hopping SRS, the access network device can receive an uplink positioning reference signal (SRS) that is equivalent to or similar to a broadband signal according to an SRS frequency-hopping pattern, thereby improving positioning accuracy.
[0143] In the first example above, assuming both the first and second signals are periodic, and the access network device configures more than one periodic frequency-hopping SRS resource for transmission within the first time period, or more than one periodic frequency-hopping resource overlaps within the first time period, the terminal only transmits the periodic frequency-hopping SRS transmitted earliest within the first time period and discards other periodic frequency-hopping SRSs with later transmission start times. This ensures that a complete periodic frequency-hopping SRS is transmitted, and eliminates the need to transmit other periodic frequency-hopping SRSs, thereby saving terminal power consumption.
[0144] Assuming that both the first signal and the second signal are aperiodic signals, and the access network device triggers more than one aperiodic signal to be sent within the first time period, or more than one aperiodic resource overlaps within the first time period, the terminal only sends the earliest aperiodic signal sent within the first time period and discards other aperiodic signals with later start times. The network and the terminal have a consistent understanding of the terminal's behavior.
[0145] Assuming that both the first signal and the second signal are semi-persistent signals, and the access network device activates more than one semi-persistent signal to be sent within the first time period, or more than one semi-persistent resource overlaps within the first time period, the terminal only sends the semi-persistent signal sent earliest within the first time period and discards other semi-persistent signals with later start times. The network and the terminal have a consistent understanding of the terminal's behavior.
[0146] In another example, the first signal is a non-periodic signal, and the second signal is a periodic signal or a semi-persistent signal. In addition to triggering a non-periodic signal to be sent within the first time period, the access network device also configures a periodic signal or activates a semi-persistent signal to be sent within the first time period, or the non-periodic resources overlap with the periodic or semi-persistent resources within the first time period. Since the priority and urgency of the non-periodic signal are higher than those of the periodic or semi-persistent signal, the terminal only sends the non-periodic signal within the first time period and discards the periodic or semi-persistent signal. The network side and the terminal have a consistent understanding of the behavior of the terminal.
[0147] The first time period may be pre-defined by a protocol, pre-negotiated between the terminal and the access network device, or configured by the access network device. Furthermore, the method may include the following steps: the access network device sends configuration information for the first time period to the terminal. Accordingly, the terminal receives the configuration information for the first time period. The configuration information for the first time period includes at least one of the following: the starting system frame number of the first time period, the starting timeslot, the starting symbol, the period of the first time period, and the duration of the first time period. Exemplarily, the configuration of the first time period may be periodic. The configured first time period is shown in FIG8 .
[0148] The starting position of the first time period is the starting position of the second signal in the time domain, and the ending position of the first time period is the ending position of the second signal in the time domain.
[0149] Exemplarily, when the second signal is an SRS sent by frequency hopping, the second signal is sent at multiple resource locations, then the starting position of the first time period is the starting position of the earliest second signal in the time domain among the second signals, and the end position of the first time period is the end position of the latest second signal in the time domain among the second signals.
[0150] According to a communication method provided in an embodiment of the present application, the terminal itself clarifies the uplink sending behavior, reduces the constraints on the network side configuration or scheduling, clarifies the behavior of the terminal when certain configurations occur, and enables the network side and the terminal to have a consistent understanding of the terminal behavior.
[0151] Another embodiment in which the terminal specifies its own uplink sending behavior to reduce its own power consumption will be described below.
[0152] FIG12 is a flow chart of another communication method provided in an embodiment of the present application. Exemplarily, the method may include the following steps:
[0153] S1201. An access network device sends resource configuration and / or scheduling information of a first signal and configuration or scheduling information of a second signal to a terminal. Correspondingly, the terminal receives the resource configuration and / or scheduling information of the first signal and configuration or scheduling information of the second signal from the access network device.
[0154] In this embodiment, the access network device configures and / or schedules multiple resources for the first signal, and configures and / or schedules resources for the second signal. The access network device sends resource configuration and / or scheduling information for the first signal, as well as configuration or scheduling information for the second signal, to the terminal. That is, in addition to configuring multiple resources for the first signal, the access network device also configures resources for the second signal; or, the resources for the second signal overlap with at least one of the multiple resources for the first signal. "Configuration" can include sending configuration information via RRC signaling, for example, and "scheduling" can include scheduling via DCI, for example.
[0155] It is understandable that the resource configuration and / or scheduling information of the first signal and the configuration or scheduling information of the second signal can be located in the same message or in different messages. This embodiment does not limit the order in which the access network device sends the resource configuration and / or scheduling information of the first signal and the configuration or scheduling information of the second signal, nor does it limit the order in which the terminal receives the resource configuration and / or scheduling information of the first signal and the configuration or scheduling information of the second signal.
[0156] The resource configuration and / or scheduling information of the first signal is used to configure and / or schedule multiple resources for the first signal. The time domain locations of the multiple resources do not overlap, and the frequency domain locations of the multiple resources partially overlap or do not overlap at all. The first signal is a frequency-hopping signal, such as an uplink positioning reference signal (SRS) transmitted using frequency hopping. The second signal can be a frequency-hopping signal or a non-frequency-hopping signal. For the meaning of "overlap," please refer to the above description.
[0157] In which, the time domain position of at least one resource among the multiple resources of the first signal is not later than that of the second signal. In other words, the time domain position of at least one resource among the multiple resources of the first signal is earlier than that of the second signal, or the time domain position of at least one resource among the multiple resources of the first signal is the same as the time domain position of the resources of the second signal.
[0158] In one example, the first signal is a periodic signal, and the second signal is a non-periodic signal or a semi-continuous signal.
[0159] In another example, the first signal is a semi-continuous signal, and the second signal is a non-periodic signal.
[0160] S1202. In the first time period, the terminal does not send the first signal and only sends the second signal.
[0161] After the terminal receives the resource configuration and / or scheduling information of the first signal and the configuration or scheduling information of the second signal, the terminal does not send the first signal within a first time period and only sends the second signal.
[0162] In the first example above, the first signal is a periodic signal, and the second signal is a non-periodic signal or a semi-continuous signal. That is, the access network device configures the periodic signal to be sent within the first time period, and also configures the resources for the non-periodic signal or the semi-continuous signal to be sent within the first time period; or, the resources for the non-periodic signal or the semi-continuous signal overlap with the resources for the periodic signal within the first time period. Since the priority of the non-periodic signal or the semi-continuous signal is higher than that of the periodic signal, the terminal does not send the first signal (discards the first signal) and only sends the second signal within the first time period. This ensures that the high-priority signal is sent in a timely manner. For example, the non-periodic signal or the semi-continuous signal is an uplink positioning reference signal SRS, which can be a frequency-hopping SRS or a non-frequency-hopping SRS, thus meeting the emergency positioning requirements.
[0163] In the second example above, the first signal is a semi-continuous signal, and the second signal is a non-periodic signal. That is, the access network device configures the semi-continuous signal to be sent within the first time period, and also configures the resources for the non-periodic signal to be sent within the first time period; or, the resources for the semi-continuous signal overlap with the resources for the periodic signal within the first time period. Since the priority of the non-periodic signal is higher than that of the semi-continuous signal, the terminal does not send the first signal (discards the first signal) and only sends the second signal within the first time period. This ensures that the high-priority signal is sent in a timely manner. For example, the non-periodic signal is an uplink positioning reference signal SRS, which can be a frequency-hopping SRS or a non-frequency-hopping SRS, which meets the emergency positioning requirements.
[0164] The first time period may be pre-defined by a protocol, pre-negotiated between the terminal and the access network device, or configured by the access network device. Furthermore, the method may include the following steps: the access network device sends configuration information for the first time period to the terminal. Accordingly, the terminal receives the configuration information for the first time period. The configuration information for the first time period includes at least one of the following: the starting system frame number of the first time period, the starting timeslot, the starting symbol, the period of the first time period, and the duration of the first time period. Exemplarily, the configuration of the first time period may be periodic. The configured first time period is shown in FIG8 .
[0165] The starting position of the first time period is the starting position of the earliest second signal in the time domain, and the ending position of the second time period is the ending position of the latest second signal in the time domain.
[0166] In the above-mentioned embodiments, not configuring, not sending or not scheduling may be applied to overlapping symbols; the first time period may refer to the time period corresponding to the overlapping symbols.
[0167] According to a communication method provided in an embodiment of the present application, the terminal itself clarifies the uplink sending behavior, reduces the constraints on the network side configuration or scheduling, clarifies the behavior of the terminal when certain configurations occur, and enables the network side and the terminal to have a consistent understanding of the terminal behavior.
