Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] Physical uplink shared channel (PUSCH) transmission based on orthogonal cover code (OCC) sequence encoding refers to the transmission of the same data encoded by an OCC sequence by a terminal device across multiple time slots, multiple orthogonal frequency division multiplexing (OFDM) symbols, or multiple resource elements (REs) within the same slot. OCC sequences enable multiple terminal devices to repeatedly transmit data on the same time-domain resources.

[0003] If the time-frequency resources corresponding to the same data encoded by the OCC sequence overlap with the reserved resources, it will cause transmission conflicts and destroy the phase continuity of the OCC sequence encoding. Summary of the Invention

[0004] This application provides a communication method and apparatus that can avoid transmission conflicts and ensure the phase continuity of OCC sequence encoding.

[0005] In a first aspect, this application provides a communication method applied to a first communication device, comprising: determining that a first time-frequency resource overlaps with a first reserved resource; wherein the first time-frequency resource includes resources for transmitting a first data packet, the first data packet including a plurality of encoded data, the encoded data indicating data encoded based on an orthogonal overlay code sequence; transmitting at least one encoded data in the first data packet based on a second time-frequency resource; wherein the time corresponding to the second time-frequency resource is later than the time corresponding to the first reserved resource, and the second time-frequency resource does not include the reserved resource.

[0006] In the above design, when there is a conflict between the encoded data transmission based on OCC sequence encoding and the reserved resources, the transmission of part or all of the encoded data is delayed, which can avoid transmission conflicts and ensure the phase continuity of OCC sequence encoding.

[0007] In one possible design, the first data packet includes first encoded data, and the resources used to transmit the first encoded data overlap with the first reserved resources. Sending at least one encoded data item in the first data packet based on a second time-frequency resource includes sending the first encoded data based on the second time-frequency resource. This design, by delaying the transmission of encoded data that conflicts with the reserved resources, can reduce the impact of resource reservation on the decoding performance of the network side.

[0008] In one possible design, the resource used to transmit the first encoded data overlaps with the first reserved resource by multiple symbols. Optionally, if the first data packet also includes second encoded data, and the resource used to transmit the second encoded data overlaps with the first reserved resource by one symbol, the method further includes: sending the second encoded data through the resource used to transmit the second encoded data, and discarding the data in the second encoded data at the one symbol. In this design, no delayed transmission processing is performed on the encoded data overlapping by one symbol, which can reduce the complexity of data processing by the terminal device and reduce data transmission latency.

[0009] In one possible design, the encoded data in the first data packet is divided into a first part of encoded data and a second part of encoded data. The resources used to transmit the first part of encoded data overlap with the first reserved resources, while the resources used to transmit the second part of encoded data do not overlap with the first reserved resources. Sending at least one part of encoded data in the first data packet based on the second time-frequency resource includes: discarding the first part of encoded data and sending the second part of encoded data based on the second time-frequency resource. This design, by discarding the overlapping encoded data, reduces the amount of data requiring delayed transmission, thereby reducing the complexity of data processing by the terminal device and reducing data transmission latency.

[0010] In one possible design, transmitting at least one encoded data item in the first data packet based on the second time-frequency resource includes: discarding the first encoded data item in the first data packet, and transmitting the encoded data in the first data packet excluding the first encoded data item based on the second time-frequency resource. This design, by discarding only the first encoded data item and allowing processing time for the delayed transmission of subsequent encoded data, ensures the continuity of subsequent encoded data transmission and reduces the impact of resource reservation on the decoding performance of the network side.

[0011] In one possible design, if the overlap between the first time-frequency resource and the first reserved resource falls within a first time duration range, then at least one encoded data in the first data packet is transmitted based on the second time-frequency resource. This design, which determines whether data is dropped or delayed based on the degree of conflict, i.e., the length of the overlap, offers greater flexibility. It reduces the complexity of data processing for terminal devices while avoiding transmission conflicts and ensuring the phase continuity of the OCC sequence encoding.

Figure 1 As shown, Figure 1 This is a schematic diagram of the architecture of the communication system 10 used in an embodiment of this application. Figure 1 As shown, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 10 may also include an Internet 300. The RAN 100 includes at least one RAN node (e.g., ...). Figure 1 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure 1 RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1(Not shown in the image). Terminal 120 connects wirelessly to RAN node 110, and RAN node 110 connects wirelessly or via a wired connection to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes.

[0077] The network device involved in this application embodiment can be a RAN node. A RAN node, also known as a radio access network device, RAN entity, or access node, is used to help terminals access a communication system wirelessly. In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next-generation base station in a future communication system, or a base station in a future mobile communication system. A RAN node can also be a macro base station (such as...) Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b in the middle can also be a relay node or a donor node.

[0078] Terminal equipment can be any device or module that accesses the aforementioned communication system and possesses corresponding communication functions. Terminal equipment can also be referred to as user equipment (UE), terminal, user device, access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, terminal unit, terminal station, terminal device, wireless communication equipment, user agent, or user device. Terminal equipment typically contains communication modules, circuits, or chips that perform the corresponding communication functions.

[0080] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0081] The roles of base stations and terminals can be relative, for example, Figure 1The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0082] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0083] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0084] based on Figure 1 The description of the communication system architecture shown illustrates, for example, the non-terrestrial network (NTN) communication system applicable to the embodiments of this application. NTN includes nodes such as satellite networks, high-altitude platforms, and drones, and has significant advantages such as global coverage, long-distance transmission, flexible networking, convenient deployment, and no geographical limitations. It has been widely used in various fields such as maritime communication, positioning and navigation, disaster relief, scientific experiments, video broadcasting, and Earth observation. Terrestrial 5G networks and satellite networks are integrated, complementing each other's strengths, to jointly form a globally seamless, integrated sea, land, air, space, and ground communication network, meeting the ubiquitous and diverse service needs of users. In the embodiments of this application, NTN communication is exemplified by satellite communication, or in other words, the NTN communication system is exemplified by a satellite system. Figure 2As shown, the NTN communication system includes a satellite 201 and terminal equipment 202. The explanation of terminal equipment 202 can be found in the descriptions of terminal equipment 101 to 106 above. Satellite 201 can also be referred to as a high-altitude platform, high-altitude aircraft, or satellite base station. In relation to the NTN communication system and the terrestrial network communication system, satellite 201 can be considered as one or more network devices in the terrestrial network communication system architecture. Satellite 201 provides communication services to terminal equipment 202, and satellite 201 can also connect to core network equipment. The structure and functions of network equipment 202 can also be found in the description of network equipment 202 above. The communication method between satellite 201 and terminal equipment 202 can also be found in the description above. Figure 1 The description in the document is omitted here. The solutions in the embodiments of this application can also be applied directly or with slight modifications as can be conceived by those skilled in the art, and will not be described further here.

[0085] Taking 5G as an example, a 5G satellite communication system architecture is as follows: Figure 3A As shown, ground terminal equipment accesses the network via the 5G New Radio interface. 5G base stations are deployed on satellites and connected to the ground core network via wireless links. Simultaneously, wireless links exist between satellites to facilitate signaling interaction and user data transmission between base stations. Figure 3A The devices and interfaces described are as follows:

[0086] 5G Core Network: Handles services such as user access control, mobility management, session management, user security authentication, and billing. It consists of multiple functional units, which can be divided into control plane and data plane functional entities. The Access and Mobility Management (AMF) network element is responsible for user access management, security authentication, and mobility management. The User Plane Function (UPF) network element is responsible for managing user plane data transmission, traffic statistics, and other functions.

[0091] like Figure 3BAs shown in the embodiments of this application, another 5G satellite communication system architecture is also provided, in which the satellite acts as a transparent relay node.

[0092] The technical terms used in the embodiments of this application will be described below.

[0093] (1) Subcarrier and subcarrier spacing

[0094] In an orthogonal frequency division multiplexing (OFDM) system, frequency domain resources are divided into several sub-resources. Each sub-resource in the frequency domain can be called a subcarrier, which can also be understood as the smallest granularity of frequency domain resources. Subcarrier spacing refers to the interval between the center or peak positions of two adjacent subcarriers in the frequency domain in an OFDM system. Generally, uplink scheduling occupies 1, 3, 6, or 12 subcarriers in the frequency domain, and supports subcarrier spacing of 15 kHz or 3.75 kHz.

[0095] (2) PUSCH transmission based on OCC sequence encoding

[0096] In NTN, scheduling resources for different terminal devices are often differentiated using time-division or frequency-division multiplexing. Excessive repetition of data transmission by a single terminal device can lead to reduced spectral efficiency and resource utilization. Therefore, multiple terminal devices can consider reusing the same resources. Generally, due to the large coverage area of ​​satellites, terminals within the coverage area may be far apart, allowing for spatial separation of their data using two receiving beams. However, for two terminals that are close together, the propagation path between the satellite and the terminal device lacks scatterers, resulting in strong direct components in the channel. The spatial correlation between the channels from multiple terminal devices to the satellite is extremely high, making spatial separation impossible. Closely located terminal devices often have similar path losses, similar link budgets, and may require a similar number of repetitions for data transmission. Therefore, OCC sequence encoding can be used to multiplex the data of multiple terminal devices using the same time-domain resources. This method can also be called PUSCH transmission based on OCC sequence encoding.

[0097] The same terminal device can also transmit the same data encoded by OCC sequences on multiple slots, multiple OFDM symbols, or multiple REs in the same slot. The same data encoded by an OCC sequence can be understood as one OCC encoding unit. Different terminal devices can extend the data repetition through OCC sequences. For two terminal devices (such as UE1 and UE2) that multiplex the same time domain resources to transmit data, two OCC sequences can be used. Let the length of the OCC sequence be L. The first OCC sequence can be represented as {a1,…,aL}, and the second OCC sequence can be represented as {b1,…,bL}. UE1 uses the first OCC sequence to generate L repetitions of data a1, denoted as {a1×s1,…,aL×s1}. UE2 uses the second OCC sequence to generate L repetitions of data b1, denoted as {b1×s2,…,bL×s2}. The data of UE1 and UE2 are transmitted on the same time domain resources. The network device can use the first OCC sequence to parse the data of UE1 and the second OCC sequence to parse the data of UE2.

[0098] (3) Reserve resources

[0099] In scenarios where NR and NB-IoT communication coexist, reserving some resources for NR data transmission avoids interference with NB-IoT data transmission. These reserved resources can be periodic, and the level (or granularity) of the reserved resources can be subframes, time slots, or symbols. For example, reserved resources might consist of multiple periodic subframes, multiple periodic time slots, or multiple periodic symbols. It's understood that "symbol" refers to OFDM symbols. Correspondingly, the capabilities of terminal devices are categorized as supporting time slot level, supporting subframe level, supporting both subframe and time slot levels but not symbol level, or not supporting time slot level, etc.

[0100] If the time-frequency resources reused by multiple terminal devices overlap with the reserved resources, it will cause transmission conflicts and disrupt the phase continuity of the OCC coding unit, resulting in poor reception and decoding performance on the network side.

[0101] In view of this, embodiments of this application provide a communication method that can avoid transmission conflicts, ensure the phase continuity of OCC encoding units and the orthogonality between uplink transmissions of different terminals, and improve the reception and decoding performance on the network side.

[0102] like Figure 4This illustration primarily uses the interaction process between a first communication device and a second communication device as an example to describe the communication method. The first communication device can be applied to a terminal device; for example, the first communication device is a terminal device, or a device capable of implementing the functions of a terminal device, or a module within a terminal device. The second communication device can be applied to an access network device; for example, the second communication device is an access network device, or a device capable of implementing the functions of an access network device, or a module within an access network device. The method mainly includes the following steps.

[0103] S401, the first communication device determines that the first time-frequency resource overlaps with the first reserved resource.

[0104] The first time-frequency resource is a pre-configured resource for transmitting the first data packet, which includes multiple encoded data. The first time-frequency resource includes resources for transmitting each encoded data. The encoded data is data encoded based on orthogonal coverage code (OCC) sequence encoding, and can also be described as an OCC coding unit. The first reserved resource can be one of a periodically configured reserved resource, or it can be a separately configured reserved resource. The resource level can be subframe level, slot level, or symbol level. Optionally, the first reserved resource can be used for uplink data transmission in NR communication.

[0105] It is understood that the overlap between the first time-frequency resource and the first reserved resource can be an overlap in time-domain resources and / or frequency-domain resources. The overlap between the first time-frequency resource and the first reserved resource can include the following situations: there is partial or complete overlap between the resource corresponding to one coded data in the first data packet and the first reserved resource; there is partial or complete overlap between the resources corresponding to multiple coded data in the first data packet and the first reserved resource.

[0106] S402, the first communication device transmits at least one encoded data in the first data packet based on the second time-frequency resource.

[0107] The second time-frequency resource corresponds to a time later than the time corresponding to the first reserved resource, and the second time-frequency resource does not include the reserved resource. It is understood that the second time-frequency resource can carry at least one encoded data item from the first data packet.

[0108] In a first possible design, the first data packet includes first encoded data, and the resources used to transmit the first encoded data overlap with the first reserved resources. In this case, the first communication device transmits the first encoded data based on the second time-frequency resources. The first reserved resources and the second time-frequency resources in this design will be described in detail below.

[0109] Example 1: This design can be applied to scenarios where the terminal device does not support symbol-level and time-slot-level capabilities. The first reserved resource can be a subframe-level resource, for example, the first reserved resource corresponds to one subframe (the first subframe). The second time-frequency resource corresponds to one or more subframes after the first reserved resource and does not include the reserved resource. For example, if the time corresponding to the resource used to transmit the first encoded data is less than one subframe, when the first communication device determines that the resource used to transmit the first encoded data overlaps with the first subframe, it delays the transmission of the first encoded data to the next subframe after the first subframe that has not been reserved by the resource. Alternatively, if the time corresponding to the resource used to transmit the first encoded data is greater than one subframe, when the first communication device determines that the resource used to transmit the first encoded data overlaps with the first subframe, it delays the transmission of the first encoded data to multiple consecutive subframes after the first subframe that have not been reserved by the resource.

[0110] Optionally, if multiple symbols overlap between the resource used to transmit the first encoded data and the first reserved resource, the first communication device may transmit the first encoded data as described in Example 11.

[0111] Example 2: This design can be applied to scenarios where the terminal device supports slot-level capabilities but not symbol-level capabilities. The first reserved resource can be a slot-level resource. The first reserved resource corresponds to one slot (first slot), and the resource level corresponding to the second time-frequency resource is the subframe level, that is, the second time-frequency resource corresponds to at least one subframe after the first reserved resource and does not include the reserved resource; or, the first reserved resource corresponds to one slot (first slot), and the resource level corresponding to the second time-frequency resource is the slot level, that is, the second time-frequency resource corresponds to at least one slot after the first reserved resource and does not include the reserved resource.

[0112] Optionally, if multiple symbols overlap between the resource used to transmit the first encoded data and the first reserved resource, the first communication device may transmit the first encoded data as described in Example 12.

[0113] Optionally, the resource level corresponding to the second time-frequency resource can be determined by the subcarrier spacing corresponding to the uplink scheduling. For example, if the first communication device determines that the resource used to transmit the first coded data overlaps with the first time slot, and the subcarrier spacing corresponding to the uplink scheduling is 15 kHz, then the resource level corresponding to the second time-frequency resource is at the subframe level. If the subcarrier spacing corresponding to the uplink scheduling is 3.75 kHz, then the resource level corresponding to the second time-frequency resource is at the time slot level. It can be understood that the duration of the time slot corresponding to 3.75 kHz is equivalent to twice the duration of the subframe corresponding to 15 kHz, and the time slot corresponding to 3.75 kHz includes two subframes, that is, the delay granularity of 15 kHz is smaller than the delay granularity of 3.75 kHz.

[0114] Taking the resource level corresponding to the second time-frequency resource as the subframe level as an example, if the time corresponding to the resource used to transmit the first encoded data is less than one subframe, when the first communication device determines that the resource used to transmit the first encoded data overlaps with the first subframe, it delays transmitting the first encoded data on the next subframe that has not been reserved by the resource. If the time corresponding to the resource used to transmit the first encoded data is greater than one subframe, when the first communication device determines that the resource used to transmit the first encoded data overlaps with the first subframe, it delays transmitting the first encoded data on multiple consecutive subframes that have not been reserved by the resource after the first subframe. Taking the resource level corresponding to the second time-frequency resource as the time slot level as an example, if the time corresponding to the resource used to transmit the first encoded data is less than one time slot, when the first communication device determines that the resource used to transmit the first encoded data overlaps with the first time slot, it delays transmitting the first encoded data on the next time slot that has not been reserved by the resource after the first time slot. If the time corresponding to the resource used to transmit the first encoded data is greater than one time slot, when the first communication device determines that the resource used to transmit the first encoded data overlaps with the first time slot, it delays the transmission of the first encoded data to a series of consecutive time slots that have not been reserved by the resource after the first time slot.

[0115] Example 3 illustrates that this design can be applied to scenarios where the terminal device supports symbol-level capabilities. The first reserved resource can be a symbol-level resource. The first reserved resource corresponds to one or more symbols, and the second time-frequency resource corresponds to at least one subframe, at least one time slot, or at least one symbol that follows the first reserved resource but does not include the reserved resource. It is understood that the number of time slots, subframes, or symbols corresponding to the second time-frequency resource is determined by the time required to transmit the first coded data.

[0116] Optionally, the resource level corresponding to the second time-frequency resource can be determined by the subcarrier spacing corresponding to the uplink scheduling. For example, if the first communication device determines that the resource used to transmit the first coded data overlaps with the first reserved resource, and the subcarrier spacing corresponding to the uplink scheduling is 15 kHz, then the resource level corresponding to the second time-frequency resource is the symbol level, that is, the second time-frequency resource corresponds to one or more consecutive symbols after the first reserved resource, excluding the reserved resource, and supporting the carrying of the first coded data; if the subcarrier spacing corresponding to the uplink scheduling is 3.75 kHz, then the resource level corresponding to the second time-frequency resource is the time slot level, that is, the second time-frequency resource corresponds to one or more consecutive time slots after the first reserved resource, excluding the reserved resource, and supporting the carrying of the first coded data. Alternatively, if the subcarrier spacing corresponding to the uplink scheduling is 15 kHz, then the resource level corresponding to the second time-frequency resource is the time slot level, that is, the second time-frequency resource corresponds to one or more consecutive time slots after the first reserved resource, excluding the reserved resource, and supporting the carrying of the first coded data; if the subcarrier spacing corresponding to the uplink scheduling is 3.75 kHz, then the resource level corresponding to the second time-frequency resource is the subframe level, that is, the second time-frequency resource corresponds to one or more consecutive subframes after the first reserved resource, excluding the reserved resource, and supporting the carrying of the first coded data.

[0117] It is understandable that the duration of the time slot corresponding to 3.75KHz is twice the duration of the subframe corresponding to 15KHz. The time slot corresponding to 3.75KHz includes two subframes, meaning that the delay granularity of 15KHz is smaller than that of 3.75KHz.

[0118] In a second possible design, the first data packet includes first coded data and second coded data. The resource for transmitting the first coded data overlaps with a first reserved resource by multiple symbols, and the resource for transmitting the second coded data overlaps with the first reserved resource by one symbol. The first communication device can then send the first data packet as follows: the resource for transmitting the second coded data sends the second coded data, discarding data in the second coded data at the one symbol; and the first coded data is sent based on the second time-frequency resource. It is understood that in this design, the transmission time of the second coded data is earlier than the transmission time of the first coded data.

[0119] Optionally, the definition of the second time-frequency resource and the method by which the first communication device transmits the first encoded data based on the second time-frequency resource can be understood with reference to the descriptions in Examples 1 to 3, and will not be repeated in this embodiment. It is understood that the second time-frequency resource can carry the first encoded data.

[0120] In the third possible design, the encoded data in the first data packet is divided into a first part of encoded data and a second part of encoded data. The resources used to transmit the first part of encoded data overlap with the first reserved resources, while the resources used to transmit the second part of encoded data do not overlap with the first reserved resources. In this case, the first communication device can discard the first part of encoded data and send the second part of encoded data based on the second time-frequency resources.

[0121] The method by which the first communication device transmits the second portion of encoded data based on the second time-frequency resource can be understood by referring to the description of transmitting the first encoded data in Examples 1 to 3, and will not be repeated in this embodiment. It is understood that the second time-frequency resource is capable of carrying the second portion of encoded data.

[0122] In a fourth possible design, the first communication device may discard the first encoded data in the first data packet and transmit the encoded data in the first data packet other than the first encoded data based on the second time-frequency resource.

[0123] The method by which the first communication device transmits encoded data other than the first encoded data based on the second time-frequency resource can be understood by referring to the description of transmitting the first encoded data in Examples 1 to 3, and will not be repeated in this embodiment. It is understood that the second time-frequency resource can carry encoded data in the first data packet other than the first encoded data.

[0124] Optionally, the first communication device, the second communication device, or the protocol predefines a first duration range. For example, this first duration range may include two thresholds, such as a range from a lower limit of 2 symbols to an upper limit of 5 symbols. When the overlap duration between the first time-frequency resource and the first reserved resource falls within the first duration range, the first communication device transmits at least one encoded data from the first data packet based on the second time-frequency resource, as described in the above design. When the overlap duration between the first time-frequency resource and the first reserved resource is less than the lower limit of the first duration range (e.g., only one symbol overlaps), the first communication device discards the data on the overlapping symbol and transmits the remaining encoded data normally without further delay. When the overlap duration between the first time-frequency resource and the first reserved resource exceeds the upper limit of the first duration range, the first communication device may discard the entire data packet as described above for the first data packet.

[0125] S403, the second communication device receives at least one encoded data in the first data packet based on the second time-frequency resource.

[0126] The receiving process of the second communication device can be understood as corresponding to the sending process in S402, and will not be described in detail in this embodiment.

[0127] Based on the same concept, see [link / reference] Figure 5 This application provides a communication device 500, which includes a processing module 501 and a communication module 502. The communication device 500 can be a first communication device, or a communication device applied to or used in conjunction with a first communication device to implement a communication method executed on the first communication device side; alternatively, the communication device 500 can be a second communication device, or a communication device applied to or used in conjunction with a second communication device to implement a communication method executed on the second communication device side.

That is, the communication module includes a receiving unit and a sending unit.

Alternatively, the communication device can be understood with reference to the fourth aspect of the invention and the possible designs within the fourth aspect.
