Description

[Technical field]

[0001] The present application relates to the field of communications technology, and in particular to a reference signal resource configuration method and apparatus. [Background technology]

[0002] In order to improve the positioning accuracy, new radio (NR) technology is used for positioning. In the uplink-based positioning technology, the terminal transmits a reference signal, such as a sounding reference signal (SRS), based on the configuration by the base station. The base station measures the reference signal transmitted by the terminal to obtain the time of arrival or the angle of arrival of the reference signal, so as to obtain the distance and direction between the terminal and the base station and estimate the position of the terminal.

[0003] Currently, SRS is used for multiple purposes, such as beam management, codebook transmission, non-codebook transmission, and antenna switching. Now, positioning function is added, and SRS resources used for positioning and SRS resources used for other purposes are configured separately. In other words, both SRS resources used for positioning and SRS resources used for other purposes are configured simultaneously for the terminal. The terminal needs to transmit SRS resources for multiple purposes simultaneously. SRS resource configuration includes bandwidth, cycle, initial value, and time-frequency position, etc. In an example shown in FIG. 1, the cycle of SRS resources used for non-codebook transmission is different from that of SRS resources used for positioning, and the cycles of SRS resources used for positioning in different resource sets are different. For both cases, collisions on the same slot may occur. However, collisions on the same symbol may also occur for SRS resources for the same purpose with the same cycle.

[0004] Generating multiple SRS resources simultaneously or on the same symbol is a big challenge for the processing capacity of the chip of the terminal. The total chip resource used for SRS resource processing is limited, and the chip resource occupied for SRS processing changes for different purposes. For example, more resources may be occupied for processing SRS resources used for non-codebook transmission than for processing SRS resources used for positioning. Therefore, when the total processing resource is fixed, how to properly configure SRS resources for multiple purposes has become an urgent problem to be solved. Summary of the Invention

[0005] The embodiments of the present application provide a reference signal resource configuration method and apparatus for appropriately configuring reference signal resources for multiple purposes.

[0006] According to a first aspect, a reference signal resource configuration method is provided. The method includes receiving reference signal resource configuration information from a base station, and, if at least two reference signal resources indicated by the reference signal resource configuration information are located on the same orthogonal frequency division multiplexing (OFDM) symbol, mapping one of the at least two reference signal resources to the OFDM symbol.

[0007] According to this aspect, when the base station configures parallel processing of multiple reference signal resources, the terminal discards conflicting reference signal resources according to a specific rule, and appropriately configures reference signal resources for multiple purposes, thereby avoiding the collision of reference signal resources, improving communication reliability, and reducing the processing complexity of the terminal chip.

[0008] In a possible implementation, a first reference signal resource of the at least two reference signal resources is used for a first purpose and a second reference signal resource of the at least two reference signal resources is used for a second purpose, and the terminal maps only the first reference signal resource used for the first purpose to the OFDM symbol, or the first reference signal resource of the at least two reference signal resources is used for the first purpose and the second reference signal resource of the at least two reference signal resources is used for a second purpose, and the terminal maps only the second reference signal resource used for the second purpose to the OFDM symbol, or all of the at least two reference signal resources are used for a second purpose, and the terminal maps one of the at least two reference signal resources used for the second purpose to the OFDM symbol, and the first purpose includes any one of beam management, antenna switching, codebook transmission, and non-codebook transmission, and the second purpose includes positioning.

[0009] According to this aspect, if the terminal finds that the reference signal resource used for positioning and the reference signal resource used for another purpose configured by the base station appear on the same symbol, the terminal may choose to map only the reference signal resource used for positioning or the reference signal resource for another purpose. If the terminal finds that multiple reference signal resources used for positioning configured by the base station appear on the same symbol, the terminal may map one of the reference signal resources used for positioning to this symbol.

[0010] According to a second aspect, a reference signal resource configuration method is provided. The method includes transmitting reference signal resource configuration information to a terminal, and, when at least two reference signal resources indicated by the reference signal resource configuration information are located on the same OFDM symbol, receiving one of the at least two reference signal resources transmitted by the terminal on the OFDM symbol.

[0011] According to this aspect, the configuration behavior of the base station is not limited. When the base station configures parallel processing of multiple reference signal resources, the terminal discards conflicting reference signal resources according to a specific rule to appropriately configure reference signal resources for multiple purposes. This avoids the collision of reference signal resources and improves communication reliability.

[0012] In a possible implementation, a first reference signal resource of the at least two reference signal resources is used for a first purpose and a second reference signal resource of the at least two reference signal resources is used for a second purpose, and the terminal maps only the first reference signal resource used for the first purpose to an OFDM symbol, or the first reference signal resource of the at least two reference signal resources is used for the first purpose and the second reference signal resource of the at least two reference signal resources is used for a second purpose, and the terminal maps only the second reference signal resource used for the second purpose to the OFDM symbol, or all of the at least two reference signal resources are used for a second purpose, and the terminal maps one of the at least two reference signal resources used for the second purpose to the OFDM symbol, and the first purpose includes any one of beam management, antenna switching, codebook transmission, and non-codebook transmission, and the second purpose includes positioning.

[0013] According to a third aspect, a reference signal resource configuration method is provided. The method includes receiving reference signal resource configuration information from a base station, where N reference signal resources indicated by the reference signal resource configuration information are located on different OFDM symbols, where N is an integer greater than or equal to 2, and mapping the N reference signal resources indicated by the reference signal resource configuration information to different OFDM symbols.

[0014] According to this aspect, the reference signal resource configuration behavior of the base station may be limited, and time division multiplexing is performed on different reference signal resources to properly configure the reference signal resources for multiple purposes, thereby avoiding the collision of reference signal resources, improving communication reliability, and reducing the processing complexity of the terminal chip.

[0015] In a possible implementation, the N reference signal resources indicated by the reference signal resource configuration information used for positioning occupy different OFDM symbols, or the N reference signal resources indicated by the reference signal resource configuration information used for positioning and having the same cycle correspond to different slot offsets, or the N reference signal resources indicated by the reference signal resource configuration information are used for different purposes, and the N reference signal resources occupy different OFDM symbols, or the N reference signal resources correspond to different slot offsets, and the different purposes specifically include any one of beam management, antenna switching, codebook transmission, non-codebook transmission, and positioning.

[0016] In this implementation, when the base station configures reference signal resources used for positioning, different reference signal resources occupy different symbols. Alternatively, when the base station configures multiple reference signal resources used for positioning and having the same cycle, it may configure different slot offsets for the multiple reference signal resources, so that the multiple reference signal resources can be mapped to different symbols. Alternatively, when the base station configures reference signal resources for multiple purposes, only reference signal resources for the same purpose are configured on the same symbol, and multiple reference signal resources for different purposes are configured to occupy different symbols within a slot, thereby implementing time division multiplexing. Alternatively, when the base station configures reference signal resources for different purposes, it may implement time division multiplexing by configuring different slot offsets, so that the multiple reference signal resources for different purposes can be mapped to different symbols.

[0017] According to a fourth aspect, a reference signal resource configuration method is provided. The method includes a step of receiving reference signal resource configuration information to a terminal, where N reference signal resources indicated by the reference signal resource configuration information are located on different orthogonal frequency division multiplexing OFDM symbols, where N is an integer greater than or equal to 2, and a step of receiving the N reference signal resources based on the reference signal resource configuration information.

[0018] In a possible implementation, the N reference signal resources indicated by the reference signal resource configuration information used for positioning occupy different OFDM symbols, or the N reference signal resources indicated by the reference signal resource configuration information used for positioning have the same cycle and correspond to different slot offsets, or the N reference signal resources indicated by the reference signal resource configuration information are used for different purposes, and the N reference signal resources occupy different OFDM symbols, or the N reference signal resources correspond to different slot offsets, and the different purposes specifically include any one of beam management, antenna switching, codebook transmission, non-codebook transmission, and positioning.

[0020] According to this aspect, the terminal reports its capability of processing reference signal resources, and the base station appropriately configures the reference signal resources for the terminal based on the capability reported by the terminal to appropriately configure the reference signal resources for multiple purposes. This avoids the collision of reference signal resources, improves communication reliability, and reduces the processing complexity of the terminal chip. In addition, multiple reference signal resources are mapped to the same OFDM symbol, which results in improved time domain resource utilization.

[0021] In a possible implementation, the number of reference signal resources that can be mapped to the same OFDM symbol includes any one of the number of reference signal resources used for positioning that can be mapped to the same OFDM symbol and the total number of reference signal resources used for positioning and any other purpose that can be mapped to the same OFDM symbol, or the number of reference signal resources used for positioning that can be mapped to the same OFDM symbol and the total number of reference signal resources that can be mapped to the same OFDM symbol, where the any other purpose includes beam management, antenna switching, codebook transmission and non-codebook transmission.

[0065] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings in which the embodiments of the present application are described.

[0066] For example, FIG. 2 is a schematic diagram of the architecture of a communication system to which the present application is applicable. The communication system may include a core network, a radio access network (RAN) and a terminal device. The core network may include functions such as an access and mobility management function (AMF) and a location management function (LMF). The AMF may implement functions such as a gateway, and the LMF may implement functions such as a positioning center. Of course, the core network may further include other network elements not listed one by one here. The AMF and the LMF may be connected by using an NLs interface. The RAN may include one or more network devices. The network device may be, but is not limited to, an ng-eNB or a gNB. The ng-eNB is an LTE base station that accesses a 5G core network, and the gNB is a 5G base station that accesses a 5G core network. The terminal device includes one or more user equipments (UEs). The radio access network may be connected to the core network by using an NG-C interface and an AMF, and the terminal device may be connected to the radio access network by using LTE-Uu and ng-eNB, or may be connected to the radio access network by using NR-Uu, ng-eNB and gNB.

[0067] 3 is a schematic diagram of another communication system architecture to which the present application is applicable. A network device in the communication system may include a location management component (LMC). The LMC may implement some functions of the LMF, so that the 5G core network does not need to be deployed by using the AMF.

[0068] A communication system to which the embodiments of the present application are applicable may include one or more gNBs and one or more UEs. One gNB may transmit data to one or more UEs and control signaling to one or more UEs. Multiple gNBs may transmit data to one UE and control signaling to one UE simultaneously.

[0069] It should be understood that Figures 2 and 3 are merely illustrative examples and do not specifically limit the types, numbers, connection methods, etc. of network elements included in a communication system to which the present application is applicable.

[0070] The LMF in the embodiments of the present application is a device or component deployed in the core network to provide positioning functionality for the UE.

[0071] The LMC in an embodiment of the present application is a functional component of the LMF and can be integrated into the gNB on the NG-RAN side.

[0072] A base station in this application may be a device capable of communicating with a terminal. A base station may be any device having wireless transmission / reception capabilities, including, but not limited to, a NodeB (NodeB), an evolved NodeB (eNodeB), a base station in a fifth generation (5G) communication system, a base station in a future communication system, an access node in a Wi-Fi system, a wireless relay node, and a wireless backhaul node, etc. A base station may alternatively be a radio controller in a cloud radio access network (CRAN) scenario. Alternatively, a base station may be a small cell, a transmission reception point (TRP), a NodeB for gNB or 6G, etc. A specific technology and a specific device form used by a base station are not limited in the embodiments of this application.

[0073] The terminal in this application is a device having a wireless transceiver function. The device may be a device deployed on land, including indoor or outdoor devices, or a handheld device, a wearable device, or an in-vehicle device, and may be deployed on water, such as a ship, or in the air, such as an aircraft, a balloon, and a satellite. The terminal may be a mobile phone, a tablet computer (pad), a computer with wireless transmission and reception function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a wearable device, or an in-vehicle device, etc. The application scenario is not limited to the embodiments of this application. In some cases, a terminal may also be referred to as a user equipment (UE), an access terminal device, a UE unit, a mobile station, a remote station, a remote terminal device, a mobile device, a wireless communication device, a UE agent, or a UE device.

[0074] It should be noted that the terms "system" and "network" may be used interchangeably in the embodiments of the present application. "Multiple" means two or more. In view of this, in the embodiments of the present application, "multiple" may also be understood as "at least two". The term "and / or" describes a correspondence to describe related objects, and indicates that three relationships may exist. For example, A and / or B may represent three cases: only A exists, both A and B exist, and only B exists. In addition, the symbol " / " generally indicates an "or" relationship between related objects.

[0075] In the following, the uplink based positioning procedure in the embodiment of the present application will be described.

[0076] The uplink-based positioning may be, for example, an uplink-time difference of arrival (UL-TDOA)-based uplink positioning technique and an uplink-angle of arrival (UL-AOA)-based uplink positioning technique. FIG. 4 is a schematic flow chart of the uplink-based positioning according to an embodiment of the present application. The following steps are included: First, the serving base station indicates SRS configuration information to the terminal. The terminal starts to transmit the SRS after receiving the indication from the base station. Then, the base station performs positioning based on the received SRS resource, as shown in the schematic diagram of FIG. 5, the serving base station and the neighbor base station perform related measurements on the received SRS, such as measuring the time of arrival (TOA), angle of arrival (AOA) or reference signal receive power (RSRP) of the SRS. Finally, the base station reports the measurement result to the LMF or LMU, and the LMF or LMU estimates the position based on the received measurement information.

[0077] In addition, the time domain types of reference signal resources in this application are described.

[0078] Time domain types of reference signal resources include periodic reference signal resources, semi-persistent reference signal resources and aperiodic reference signal resources.

[0079] Periodic reference signal resources mean that after the configuration of higher layer radio resource control (RRC) signaling is completed, the terminal continuously transmits the reference signal resources based on the configured cycle. Semi-persistent reference signal resources mean that after the RRC configuration of the reference signal resources is completed, the terminal does not immediately transmit the reference signal resources. After the medium access control (medium access control-control element (MAC-CE)) signaling is activated, the terminal device continuously transmits the reference signal resources based on the configured cycle. The transmission is stopped only after the MAC-CE signaling is deactivated. Aperiodic reference signal resources mean that after the RRC configuration is completed, downlink control information (DCI) is required to trigger the transmission of the aperiodic reference signal resources, and the aperiodic reference signal resources are transmitted only once.

[0080] The present application provides a reference signal resource configuration method and apparatus to solve the problem that a terminal may be configured with parallel processing of reference signal resources for multiple purposes. The base station's reference signal resource configuration behavior is limited, and time division multiplexing is performed on different reference signal resources to avoid collision. Alternatively, the base station's configuration behavior is not limited. When the base station configures parallel processing of multiple reference signal resources, the terminal discards conflicting reference signal resources according to a specific rule. Alternatively, the terminal may report its ability to process reference signal resources, and the base station appropriately configures reference signal resources for the terminal based on the ability reported by the terminal. Thus, the reference signal resources for multiple purposes are appropriately configured, which avoids the collision of reference signal resources, improves communication reliability, and reduces the processing complexity of the terminal chip.

[0081] In some scenarios, the configuration behavior of the base station may not be limited. When the base station configures parallel processing of multiple reference signal resources, the terminal discards conflicting reference signal resources according to a specific rule to appropriately configure reference signal resources for multiple purposes. This avoids the collision of reference signal resources and improves communication reliability. Figure 6 is a schematic flowchart of a reference signal resource configuration method according to an embodiment of the present application. The method may include the following steps.

[0082] S101: A base station transmits reference signal resource configuration information to a terminal, where at least two reference signal resources indicated by the reference signal resource configuration information are located on the same OFDM symbol.

[0083] In response, the terminal receives reference signal resource configuration information transmitted by the base station.

[0084] Before the terminal transmits the reference signal resource, the base station needs to configure the transmission of the reference signal resource, and configure the bandwidth, cycle, initialization value and time-frequency location of the reference signal resource, etc. As mentioned above, the reference signal resource can be used for multiple purposes, such as beam management, antenna switching, codebook transmission, non-codebook transmission and positioning. The multiple reference signal resources configured by the base station can be located on the same OFDM symbol. This embodiment does not limit the configuration behavior of the base station. Therefore, the base station transmits reference signal resource configuration information to the terminal after configuring multiple reference signal resources. At least two reference signal resources indicated by the reference signal resource configuration information are located on the same OFDM symbol. Specifically, the base station may transmit the reference signal resource configuration information via RRC signaling or system information, etc. The terminal receives the reference signal resource configuration information transmitted by the base station.

[0085] S102: A terminal maps one of the at least two reference signal resources to an OFDM symbol.

[0086] When a base station configures multiple reference signal resources for parallel processing, a terminal needs to discard conflicting reference signal resources according to certain rules to properly configure reference signal resources for multiple purposes and avoid collision of reference signal resources.

[0087] In this embodiment, in order to avoid collisions between reference signal resources, a terminal maps one of at least two reference signal resources to an OFDM symbol.

[0088] The terminal may discard the conflicting reference signal resources according to a certain rule. Specifically, there may be several implementations as follows:

[0089] In one implementation, a first reference signal resource of the at least two reference signal resources is used for a first purpose, and a second reference signal resource of the at least two reference signal resources is used for a second purpose, and the terminal maps only the first reference signal resource used for the first purpose to an OFDM symbol. The first purpose includes one of beam management, antenna switching, codebook transmission, and non-codebook transmission, and the second purpose includes positioning. Specifically, when the terminal finds that the reference signal resource used for positioning and the reference signal resource used for the first purpose configured by the base station appear on the same OFDM symbol, the terminal discards the reference signal resource used for positioning and transmits only the reference signal resource used for the first purpose on the OFDM symbol.

[0090] Further referring to the schematic diagram of parallel processing of SRS resources for different purposes shown in FIG. 1, in a case where the SRS resources in SRS resource set 1 used for non-codebook transmission and the SRS resources in SRS resource set 2 used for positioning are simultaneous (in other words, overlap on a symbol), when the terminal receives the configuration information transmitted by the base station, the terminal maps only the SRS resources used for non-codebook transmission to one OFDM symbol.

[0091] Since the configuration behavior of the base station is not limited, the base station may configure a plurality of first reference signal resources and a plurality of second reference signal resources. For example, the terminal may discard a plurality of second reference signal resources. In the case of a plurality of first reference signal resources, for example, a first reference signal resource having a lower time domain behavior priority is discarded. If there are at least two first reference signal resources with the same time domain behavior, a first reference signal resource with a shorter cycle may be discarded. If there are at least two more first reference signal resources with the same cycle, the terminal may randomly select and map one of the at least two first reference signal resources. Alternatively, the terminal may alternately transmit the at least two first reference signal resources, for example, transmit a first reference signal resource in a first cycle and transmit another first reference signal resource in the next cycle. The order of performing the discard operation in the above example may be further adjusted. This is not limited in the present application.

[0092] For example, the base station configures four SRS resources. Two SRS resources are used for positioning, and two SRS resources are used for beam management. In this case, the terminal first discards the two SRS resources used for positioning. Then, it is assumed that one of the two SRS resources used for beam management is periodic and the other is aperiodic. The priority of the time domain behavior of the reference signal resource is aperiodic > semi-persistent > periodic. The terminal discards the periodic SRS resource and maps only the aperiodic SRS resource to the OFDM symbol. Alternatively, it is assumed that both of the two SRS resources used for beam management are aperiodic, and the cycle of one SRS resource is longer than that of the other SRS resource. In this case, the terminal discards the SRS resource with the shorter cycle, and maps only the SRS resource with the longer cycle to the OFDM symbol.

[0093] In another implementation, a first reference signal resource of the at least two reference signal resources is used for a first purpose, a second reference signal resource of the at least two reference signal resources is used for a second purpose, and the terminal maps only the second reference signal resource used for the second purpose to the OFDM symbol. The first purpose and the second purpose have the same meaning as described above. Specifically, when the terminal finds that the reference signal resource used for positioning and the reference signal resource used for the first purpose configured by the base station appear on the same OFDM symbol, the terminal discards the reference signal resource used for the first purpose and transmits only the reference signal resource used for positioning on the OFDM symbol. If the base station configures multiple first reference signal resources and multiple second reference signal resources, the terminal may discard other reference signal resources by referring to the above-mentioned rules for the terminal to discard / select reference signal resources in the above-mentioned implementation, and map the selected reference signal resource to the OFDM symbol.

[0094] In another implementation, at least two reference signal resources are all used for a second purpose, and the terminal maps one of the at least two reference signal resources used for the second purpose to an OFDM symbol. The second purpose is positioning. Specifically, when the terminal finds that multiple reference signal resources used for positioning configured by the base station appear on the same OFDM symbol, the terminal may map one of the reference signal resources used for positioning to an OFDM symbol. When the base station configures multiple reference signal resources used for positioning, the terminal may discard other reference signal resources by referring to the above-mentioned rules for the terminal to discard / select reference signal resources in the above-mentioned implementation, and map the selected reference signal resource to an OFDM symbol.

[0095] With further reference to the schematic diagram of parallel processing of SRS resources for the same purpose shown in FIG. 1, when an SRS resource in SRS resource set 2 used for positioning and an SRS resource in SRS resource set 3 used for positioning are simultaneous (in other words, overlap on a symbol), the terminal may discard the SRS resource in resource set 2 or resource set 3 and map one of the SRS resources in these resource sets to the OFDM symbol.

[0096] It may be understood that the simultaneous reference signal resources in this embodiment belong to the same time domain type (periodic, semi-persistent or aperiodic) (regardless of purpose), in other words, the simultaneous reference signal resources are periodic, or the simultaneous reference signal resources are semi-persistent, or the simultaneous reference signal resources are aperiodic.

[0097] S103: The terminal transmits, to the base station, one of the at least two reference signal resources mapped to the OFDM symbol.

[0098] In response, the base station receives one of the at least two reference signal resources mapped to the OFDM symbol.

[0099] In the above step, the terminal discards one of the at least two reference signal resources and maps one of the at least two reference signal resources to an OFDM symbol. As a result, the terminal transmits one of the at least two reference signal resources mapped to the OFDM symbol to the base station. Since the terminal processes the conflicting reference signal resources, the base station can receive one of the at least two reference signal resources mapped to the OFDM symbol in a timely manner.

[0100] Furthermore, since the base station receives one of the at least two reference signal resources mapped to an OFDM symbol, when the base station later configures a reference signal resource for the terminal, the base station does not configure the terminal to simultaneously use the at least two reference signal resources on the same OFDM symbol.

[0101] According to the reference signal resource configuration method provided in this embodiment of the present application, when the base station configures the parallel processing of multiple reference signal resources, the terminal discards the conflicting reference signal resources according to a specific rule, and appropriately configures the reference signal resources for multiple purposes, thereby avoiding the collision of reference signal resources, improving communication reliability, and reducing the processing complexity of the terminal chip.

[0102] In another scenario, the reference signal resource configuration behavior of the base station may be limited, and time division multiplexing is performed on different reference signal resources to properly configure the reference signal resources for multiple purposes. This avoids the collision of reference signal resources and improves communication reliability. Figure 7 is a schematic flow chart of another reference signal resource configuration method according to an embodiment of the present application. The method may include the following steps.

[0103] S201: A base station sends reference signal resource configuration information to a terminal, where N reference signal resources indicated by the reference signal resource configuration information are located on different OFDM symbols, and N is an integer greater than or equal to 2.

[0104] In response, the terminal receives reference signal resource configuration information.

[0105] As described above, a reference signal resource can be used for multiple purposes, such as beam management, antenna switching, codebook transmission, non-codebook transmission, and positioning. A terminal needs to transmit multiple reference signal resources used for different or the same purpose to a base station. Before a terminal transmits a reference signal resource, the base station needs to configure the transmission of the reference signal resource and configure the bandwidth, cycle, initialization value, and time-frequency location of the reference signal resource, etc. This embodiment may limit the configuration by the base station. Specifically, the base station configures multiple reference signal resources to be located on different OFDM symbols. The base station transmits reference signal resource configuration information to a terminal. Multiple reference signal resources indicated by the reference signal resource configuration information are located on different OFDM symbols. Specifically, the base station may transmit the reference signal resource configuration information via RRC signaling, system information, etc. The terminal receives the reference signal resource configuration information.

[0106] S202: A terminal maps N reference signal resources indicated by the reference signal resource configuration information to different OFDM symbols.

[0107] After receiving the reference signal resource configuration information, the terminal maps the multiple reference signal resources indicated by the reference signal resource configuration information to different OFDM symbols to avoid collisions between the multiple reference signal resources.

[0108] Specifically, in one implementation, the N reference signal resources for positioning indicated by the reference signal resource configuration information occupy different OFDM symbols. In other words, when the base station configures the reference signal resources for positioning, the different reference signal resources occupy different OFDM symbols. For example, Figure 8 is a schematic diagram of configuring multiple reference signal resources (12 OFDM symbols) in one slot. Different starting symbol positions are configured for resource-1 for positioning and resource-2 for positioning in one slot, and different symbol positions are occupied to avoid collision.

[0109] In another implementation, the N reference signal resources used for positioning and indicated by the reference signal resource configuration information that have the same cycle correspond to different slot offsets. Specifically, when the base station configures multiple reference signal resources used for positioning and that have the same cycle, the base station may configure different slot offsets for the multiple reference signal resources, so that the multiple reference signal resources can be mapped to different OFDM symbols. Figure 9 is a schematic diagram of configuring multiple reference signal resources in multiple slots. Although the cycle of both resource-1 used for positioning and resource-3 used for positioning is 4 slots, resource-1 and resource-3 are located at different slot offsets, so that resource-1 and resource-3 can be mapped to different OFDM symbols to avoid collision.

[0110] In another implementation, the N reference signal resources indicated by the reference signal resource configuration information are used for different purposes, and the N reference signal resources occupy different OFDM symbols. The different purposes specifically include any one of the following purposes: beam management, antenna switching, codebook transmission, non-codebook transmission, and positioning. In other words, when the base station configures reference signal resources for multiple purposes, only reference signal resources for the same purpose are configured on the same OFDM symbol, and multiple reference signal resources for different purposes are configured to occupy different OFDM symbols in a slot, thereby implementing time division multiplexing. Further, see Figure 8. Resource-1 used for positioning and resource-3 used for another purpose occupy different symbol positions in one slot to avoid collision.

[0111] In another implementation, the N reference signal resources indicated by the reference signal resource configuration information are used for different purposes, and the N reference signal resources correspond to different slot offsets. The meaning of different purposes is the same as that described above. Specifically, when configuring reference signal resources for different purposes, the base station may implement time division multiplexing by configuring different slot offsets, so that multiple reference signal resources for different purposes can be mapped to different OFDM symbols. Further, see Figure 9. Resource-1 used for positioning and resource-2 used for another purpose have different slot offsets. The slot offset of resource-1 is {0}, and the slot offset of resource-2 is {2}. Therefore, resource-1 and resource-2 can be mapped to different OFDM symbols.

[0112] S203: The terminal transmits, to the base station, the N reference signal resources mapped to different OFDM symbols.

[0113] In response, the base station receives the N reference signal resources based on the reference signal resource configuration information.

[0114] The terminal maps the N reference signal resources indicated by the reference signal resource configuration information to different OFDM symbols, and then transmits the multiple reference signal resources mapped to different OFDM symbols to the base station. The base station receives the multiple reference signal resources for measurements for the same purpose or different purposes.

[0115] According to the reference signal resource configuration method provided in this embodiment of the present application, the reference signal resource configuration behavior of the base station is limited, and time division multiplexing is performed on different reference signal resources to properly configure the reference signal resources for multiple purposes, thereby avoiding the collision of reference signal resources, improving communication reliability, and reducing the processing complexity of the terminal chip.

[0116] In yet another scenario, the terminal may report its capability to process reference signal resources, and the base station appropriately configures the reference signal resources for the terminal based on the capability reported by the terminal to appropriately configure the reference signal resources for multiple purposes. This avoids the collision of reference signal resources and improves communication reliability. Figure 10 is a schematic flow chart of another reference signal resource configuration method according to an embodiment of the present application. The method may include the following steps.

[0117] S301: A terminal reports capability information to a base station, where the capability information indicates a supported number of reference signal resources that can be mapped to the same OFDM symbol.

[0118] In response, the base station receives the capability information reported by the terminal.

[0119] Whether a terminal can simultaneously use reference signal resources on the same OFDM symbol depends on the chip processing capability of the terminal, etc., specifically, on the number of reference signal resources supported by the terminal that can be mapped to the same OFDM symbol.

[0120] In this embodiment, the terminal reports capability information to the base station. The capability information indicates the number of reference signal resources supported that can be mapped to the same OFDM symbol. The base station receives the capability information reported by the terminal, so that the base station can obtain the number of reference signal resources supported by the terminal that can be mapped to the same OFDM symbol.

[0121] S302: A base station transmits reference signal resource configuration information to a terminal, where the number of reference signal resources indicated by the reference signal resource configuration information does not exceed the capability information.

[0122] In response, the terminal receives reference signal resource configuration information from the base station.

[0123] After receiving the capability information reported by the terminal, the base station configures reference signal resources for the terminal based on the capability of the terminal. The number of simultaneous reference signal resources on the same OFDM symbol configured by the base station for the terminal does not exceed the aforementioned capability information. Therefore, the base station transmits reference signal resource configuration information to the terminal. The number of reference signal resources indicated by the reference signal resource configuration information does not exceed the capability information. The base station may transmit the reference signal resource configuration information via RRC signaling or system information, etc.

[0124] S303: The terminal maps the number of reference signal resources indicated by the reference signal resource configuration information to an OFDM symbol based on the reference signal resource configuration information.

[0125] The base station delivers reference signal resource configuration information according to the capability information reported by the terminal. Thus, after receiving the reference signal resource configuration information, the terminal maps at least one reference signal resource to an OFDM symbol according to the reference signal resource configuration information. The number of the mapped reference signal resources does not exceed the capability of the terminal.

[0126] S304: The terminal transmits the number of reference signal resources indicated by the reference signal resource configuration information to the base station on the OFDM symbol.

[0127] In response, the base station receives the number of reference signal resources indicated by the reference signal resource configuration information over the OFDM symbol based on the reference signal resource configuration information.

[0128] The terminal maps the reference signal resource to the OFDM symbol based on the reference signal resource configuration information, and then transmits the reference signal resource to the base station on the OFDM symbol. The reference signal resource can be used for one or more purposes. In this embodiment, multiple reference signal resources can be mapped to the same OFDM symbol, which improves time domain resource utilization.

[0129] Specifically, the capability information reported by the terminal may include some of the following implementations:

[0130] In one implementation, the terminal reports the number of reference signal resources used for positioning that can be mapped to the same OFDM symbol, and the total number of reference signal resources used for positioning and any other purpose that can be mapped to the same OFDM symbol, including beam management, antenna switching, codebook transmission, and non-codebook transmission.

[0131] For example, the terminal reports the number N1 of SRS resources used for positioning that can be mapped to the same OFDM symbol. Possible candidate values ​​of N1 are {1, 2, 4, 6, 8}. The terminal reports the total number N1+N2 of SRS resources used for positioning and non-codebook transmission that can be mapped to the same OFDM symbol. Possible candidate values ​​of N1+N2 are {1, 2, 4, 8, 12}. In addition, the terminal may further report in advance the number N2 of SRS resources used for non-codebook transmission (or codebook transmission, beam management, or antenna switching) that can be mapped to the same OFDM symbol by the terminal, or the base station may be notified of such number N2 in advance. Possible candidate values ​​of N2 are {1, 2, 3, 4}. It may be understood that the candidate values ​​of N1 and N2 are merely examples.

[0132] Specifically, for example, if the number N1 of SRS resources used for positioning that can be mapped to the same OFDM symbol reported by the terminal is 4, the total number N1+N2 of SRS resources used for positioning and non-codebook transmission that can be mapped to the same OFDM symbol reported by the terminal is 6, and the number N2 of SRS resources used for non-codebook transmission (or codebook transmission, beam management, or antenna switching) that can be mapped to the same OFDM symbol by the terminal is 4, the SRS resources that can be configured on the same OFDM symbol by the base station must satisfy N1≦4, N2≦4, and N1+N2≦6.

[0133] Regarding the above capability information, the following Table 1 shows examples of several base station configurations. [Table 1] [Table 1]

[0134] It can be seen from Table 1 that if the number of SRS resources used for positioning is 5 and the number of SRS resources used for non-codebook transmission is 1, this configuration by the base station is not supported because the number of SRS resources used for positioning exceeds the number of SRS resources used for positioning that can be mapped to the same OFDM symbol reported by the terminal (in the above example, the number reported by the terminal is 4). If the number of SRS resources used for positioning is 4 and the number of SRS resources used for non-codebook transmission is 4, the total number of SRS resources used for positioning and SRS resources used for non-codebook transmission is 8, which exceeds the total number of SRS resources used for positioning and SRS resources used for non-codebook transmission reported by the terminal (in the above example, the number reported by the terminal is 6).

[0135] In another implementation, the terminal reports the number of reference signal resources used for positioning that can be mapped to the same OFDM symbol and the total number of reference signal resources that can be mapped to the same OFDM symbol, where the total number is the total number of reference signal resources used for multiple purposes that can be mapped to the same OFDM symbol by the terminal, where the multiple purposes include beam management, antenna switching, codebook transmission, non-codebook transmission, and positioning.

[0136] For example, the terminal reports the number N3 of reference signal resources used for positioning that can be mapped to the same OFDM symbol. Candidate values ​​of N3 are {1, 2, 4, 6, 8}. The terminal also reports the total number N4 of reference signal resources that can be mapped to the same OFDM symbol by the terminal. Candidate values ​​of N4 are {1, 2, 4, 8, 12}. It can be understood that the candidate values ​​of N3 and N4 are only examples. It can be understood that if N3=1 and N4=1 are reported, this indicates that the terminal does not support parallel processing of reference signal resources used for positioning and reference signal resources used for other purposes, and does not expect reference signal resources used for positioning and reference signal resources used for other purposes to be configured by the base station to be located on the same OFDM symbol.

[0137] Specifically, for example, if the number N3 of reference signal resources used for positioning that can be mapped to the same OFDM symbol reported by a terminal is 4, and the total number N4 of reference signal resources that can be mapped to the same OFDM symbol by the terminal is 8, the SRS resources that can be configured on the same OFDM symbol by the base station must satisfy N3≦4 and N4≦8.

[0138] Regarding the above capability information, the following Table 2 shows examples of several base station configurations. [Table 2] [Table 2]

[0139] In Table 2, the total number of SRS resources used for positioning and SRS resources used for other purposes is 10, which is greater than the total number N4 (in the above example, N4=8) of reference signal resources that can be mapped to the same OFDM symbol by the terminal. Therefore, this configuration by the base station is not supported.

[0140] In another implementation, the terminal reports the number N5 of reference signal resources used for positioning that can be mapped to the same OFDM symbol. For example, the terminal reports N5. Candidate values ​​for N5 are {1, 2, 4, 6, 8, 16}. The base station configures the reference signal resources used for positioning for the terminal based on the capability information reported by the terminal. The number of configured reference signal resources used for positioning does not exceed N5.

[0141] The terminal does not report the number of alternative reference signal resources that may be mapped to the same OFDM symbol, but the base station needs to configure the alternative reference signal resources. If the terminal finds that the reference signal resources used for positioning and the reference signal resources used for alternative purposes configured by the base station collide on the OFDM symbol, the terminal may have the following collision resolution scheme.

[0142] One collision resolution scheme is that if the reference signal resource used for positioning and the reference signal resource used for another purpose have the same time-domain behavior, the terminal may only map the reference signal resource used for the other purpose to an OFDM symbol. The same time-domain behavior means that both the reference signal resource used for positioning and the reference signal resource used for the other purpose are periodic reference signal resources, semi-persistent reference signal resources, or aperiodic reference signal resources.

[0143] Another collision resolution scheme is that if a reference signal resource used for positioning and a reference signal resource used for another purpose have the same time domain behavior, the terminal may map only the reference signal resource used for positioning to an OFDM symbol.

[0144] Another collision resolution scheme is that if a reference signal resource used for positioning and a reference signal resource used for another purpose have the same time domain behavior, the terminal may map only the reference signal resource with a longer cycle onto an OFDM symbol.

[0145] Another collision resolution scheme is that when the reference signal resources used for positioning and the reference signal resources used for other purposes have different time domain behaviors, the terminal may map the reference signal resources with the higher time domain behavior to the OFDM symbol. The reference signal resources used for positioning and the reference signal resources used for other purposes have different time domain behaviors. For example, the reference signal resources used for positioning may be periodic and the reference signal resources used for other purposes may be semi-persistent, or the reference signal resources used for positioning may be aperiodic and the reference signal resources used for other purposes may be semi-persistent.

[0146] For example, the priority of the time domain behavior of the reference signal resource is aperiodic>semi-persistent>periodic. Specifically, if an aperiodic reference signal resource collides with a periodic or semi-persistent reference signal resource on the same OFDM symbol, the terminal preferentially transmits the aperiodic reference signal resource and discards another conflicting reference signal resource on this symbol; or, if a semi-persistent reference signal resource collides with a periodic reference signal resource on the same OFDM symbol, the terminal preferentially transmits the semi-persistent reference signal resource and discards another conflicting reference signal resource on this symbol.

[0147] In another implementation, the terminal reports a total number N6 of reference signal resources that can be mapped to the same OFDM symbol. For example, the terminal reports N6. Candidate values ​​for N6 are {1, 2, 4, 6, 8, 16}. The base station configures reference signal resources used for one or more purposes for the terminal based on the capability information reported by the terminal. The number of configured reference signal resources does not exceed N6.

[0148] According to the reference signal resource configuration method provided in this embodiment of the present application, a terminal reports its capability of processing reference signal resources, and a base station appropriately configures reference signal resources for the terminal according to the capability reported by the terminal, so as to appropriately configure reference signal resources for multiple purposes. This avoids collision of reference signal resources, improves communication reliability, and reduces the processing complexity of terminal chip. In addition, at least one reference signal resource is mapped to the same OFDM symbol, so as to improve time domain resource utilization.

[0149] Based on the same concept as the above-mentioned reference signal resource configuration method, an embodiment of the present application further provides a terminal. As shown in FIG.

[0158] According to the base station provided in this embodiment of the present application, the configuration behavior of the base station is not limited. When the base station configures the parallel processing of multiple reference signal resources, the terminal discards conflicting reference signal resources according to a specific rule, and appropriately configures reference signal resources for multiple purposes.
