Description

[Technical Field]

[0001] TECHNICAL FIELD This application relates to the field of communications, and more particularly to wireless communication methods and apparatus. [Background technology]

[0002] With the development of communication technology, in order to improve the network coverage capability, data units (DUs) and radio units (RUs) can be located in different geographical locations to jointly provide services to users. When the enhanced common public radio interface (eCPRI) is the interface connecting the DU and RU, the eCPRI divides the baseband processing of the gNodeB into two parts: the DU side is called the baseband processing unit (BBH) of the baseband unit (BBU), and the RU side is called the baseband processing unit (BBL) of the active antenna unit (AAU).

[0003] In current technology, the division and deployment solutions for uplink and downlink channels on the BBH and BBL are semi-statically determined using a negotiation mechanism between the BBH and BBL during system startup. However, the division and deployment of channels on the BBL and BBH are essentially independent of each other. In addition, the actual usage of some channels on the BBL in a live network is far less than the designed processing capacity, and the processing specifications of other channels are usually limited. This limits the performance improvement of wireless communication systems.

[0004] Therefore, there is an urgent need for a communication method that supports dynamic and flexible channel division and deployment, fully utilizes the processing power on the BBL side, and improves wireless communication performance. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0048] The technical solutions of the present application are described below with reference to the accompanying drawings.

[0049] The technical solutions of the embodiments of the present application may be applied to various communication systems, such as a long term evolution (LTE) system, a frequency division duplex (FDD) system, a time division duplex (TDD) system, a fifth generation (5G) system or new radio (NR), and a sixth generation (6G) system, or future communication systems. The 5G mobile communication system in the present application includes a non-standalone (NSA) 5G mobile communication system or a standalone (SA) 5G mobile communication system. The communication system may alternatively be a public land mobile network (PLMN), a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, an Internet of things (IoT) communication system, a vehicle-to-everything (V2X) communication system, an unmanned aerial vehicle (UAV) communication system, or another communication system.

[0050] In addition, the network architectures and service scenarios described in the embodiments of the present application are intended to more clearly explain the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions provided in the embodiments of the present application. As those skilled in the art can understand, with the evolution of network architectures and the emergence of new service scenarios, the technical solutions provided in the embodiments of the present application can also be applied to similar technical problems.

[0051] To facilitate understanding of the embodiments of the present application, the application scenario of the embodiments of the present application will be described in detail first with reference to FIG.

[0052] 1 is a diagram of the structure of a communication system to which an embodiment of the present application can be applied. First, a description will be given of devices that can be included in this communication system.

[0053] Radio unit (RU) 110: The radio unit 110 can perform functions such as intermediate frequency processing, radio frequency processing, and signal duplexing. For example, the radio unit 110 can be a remote radio unit (RRU), an active antenna unit (AAU), an open-radio unit (O-RU) in an open-radio access network (O-RAN), or other network element or communication device capable of processing intermediate frequency signals, radio frequency signals, or intermediate radio frequency signals.

[0054] Data unit (DU) 120: The data unit 120 can perform baseband signal processing functions. For example, the data unit 120 may be a baseband unit (BBU), a central unit (CU), a distributed unit (DU), an open-distributed unit (O-DU) in an O-RAN, or other network element or communication device with baseband signal processing capabilities. A module configured to perform baseband processing in the data unit 120 may be referred to as a baseband board, and there may be one or more baseband boards.

[0055] The communication interface between the data unit 120 and the radio unit 110 may be referred to as a fronthaul interface. For example, the fronthaul interface may be a common public radio interface (CPRI), an enhanced common public radio interface (eCPRI), or any other interface defined in the future and used to connect the data unit 120 and the radio unit 110. This is not specifically limited in this application.

[0056] CPRI is typically used as the primary communication interface specification between radio equipment control (REC) and radio equipment (RE) in cellular wireless networks, and CPRI rates are directly proportional to the number of antennas and carrier bandwidth. As the number of antennas and bandwidth in NR networks increase, the requirements for CPRI rates become increasingly higher, significantly increasing transmission costs. Data transmitted in the communication protocol stack is encapsulated at each layer, with more data being transmitted at lower layers. Therefore, eCPRI is introduced. At the physical layer, data from higher layers is processed on the BBU, and data from lower layers is processed on the RRU, thereby reducing transmission speed requirements.

[0057] When eCPRI is the interface connected between the DU and the RU, eCPRI divides the baseband processing of the gNodeB into two parts, the DU side is called the baseband processing unit of the BBU (base band high, BBH), and the RU side is called the baseband processing unit of the AAU (base band low, BBL).

[0058] The various interfaces can use various functional division schemes, and the various interfaces will be described below using an example of an O-RAN system to which the embodiments of the present application are applicable.

[0059] Figure 2 is a system diagram of an access network. The access network device includes one or more functional modules configured to process signals. As shown in Figure 2, physical layer functions are used as an example. The access network device includes one or more of the following functions: encoding, rate matching, scrambling, modulation, layer mapping, precoding, resource element (RE) mapping, digital beamforming (BF), inverse fast Fourier transformation (IFFT) / cyclic prefix (CP) addition, decoding, rate de-matching, descrambling, demodulation, inverse discrete Fourier transformation (IDFT), channel equalization (or channel estimation), RE demapping, and one or more of digital BF, fast Fourier transformation (FFT) / CP removal, digital-to-analog (DA) conversion, analog BF (uplink direction), analog-to-digital (AD) conversion, or analog BF (downlink direction).

[0060] One or more functional modules may be implemented by software, hardware, or a combination of software and hardware, and may be physically separated or integrated. It should be understood that the aforementioned functional modules are merely examples. The access network device may include more other modules (e.g., a scheduling module, a power control module, a hybrid automatic repeat request (HARQ) module, a flow control module, a mobility management module, or an artificial intelligence (AI) module) based on the design, or may not include the specific functional modules shown in FIG. 2 (e.g., a digital BF module). The access network device further includes a fronthaul (FH) interface between the DU and the RU, configured to implement communication between the DU and the RU. The fronthaul interface includes, but is not limited to, CPRI or eCPRI. In one possible implementation, the DU is located in the BBU, the RU is located in the RRU / AAU / RRH, and the interface between the BBU and the RRU / AAU / RRH may also be referred to as a fronthaul interface. To implement a fronthaul interface, the BBU and the RRU / AAU / RRH may be connected through a fronthaul network, or the DU and the RU may be connected through a fronthaul network. For example, the fronthaul network includes, but is not limited to, an optical fiber direct connect network and a wavelength division network.

[0061] An access network device can support one or more categories of fronthaul interfaces. The various fronthaul interfaces correspond to DUs and RUs with various functions. As shown in FIG. 2, when the fronthaul interface between the DU and RU is CPRI, the DU is configured to perform one or more baseband functions, and the RU is configured to perform one or more radio frequency functions. When the fronthaul interface between the DU and RU is eCPRI, compared to CPRI, some downlink and / or uplink baseband functions are moved from the DU to the RU for implementation. Various division schemes between the DU and RU correspond to various categories of eCPRI (abbreviated as "Cat"). FIG. 2 provides six eCPRI examples represented by Cat A, B, C, D, E, and F (which may also be represented as Option A to F, Option 1 to 6, or another scheme). It should be understood that other division schemes between the DU and RU may exist, i.e., other categories of eCPRI may exist.

[0062] Using eCPRI Cat A as an example, for downlink transmission, layer mapping is used as the division. The DU is configured to perform layer mapping and one or more previous functions (specifically, one or more of coding, rate matching, scrambling, modulation, and layer mapping). Other functions after layer mapping (e.g., one or more of RE mapping, digital BF, or IFFT / CP addition) are removed to the RU for implementation. For uplink transmission, RE demapping is used as the division. The DU is configured to perform demapping and one or more previous functions (specifically, one or more of decoding, rate demapping, descrambling, demodulation, IDFT, channel equalization, and RE demapping). Other functions after demapping (e.g., one or more of digital BF or FFT / CP removal) are removed to the RU for implementation.

[0063] Similarly, eCPRI Cat B, Cat C, Cat D, Cat E, and Cat F each correspond to different DU and RU segmentation schemes. The segmentation point and pre-segmentation functions are performed by the DU, while the post-segmentation functions are performed by the RU. See Figure 2 for the segmentation points of various eCPRI categories. Details are omitted. For example, in the case of eCPRI Cat B, RE mapping is used for segmentation of downlink transmissions, and RE demapping is used for segmentation of uplink transmissions. For uplink transmissions, RE mapping and pre-RE mapping functions are performed by the DU, while post-RE mapping and radio frequency functions are performed by the RU. For downlink transmissions, RE demapping and pre-RE demapping functions are performed by the DU, while post-RE demapping and radio frequency functions are performed by the RU.

[0064] The eCPRI partitioning scheme may be symmetric with respect to the uplink and downlink, such as eCPRI Cat B and Cat C shown in Figure 2. Alternatively, the eCPRI partitioning scheme may be asymmetric with respect to the uplink and downlink, such as eCPRI Cat A, Cat D, Cat E, and Cat F shown in Figure 2. This is not limiting. Optionally, different partitioning schemes may be configured for different channels or different channel groups for the uplink and / or downlink, in other words, different categories of eCPRI are configured. A group of channels may include one or more channels.

[0065] In one possible design, the DU is located in the BBU, the RU is located in the RRU / AAU / RRH, a processing unit configured to perform baseband functions in the BBU is referred to as a baseband high (BBH) unit, and a processing unit configured to perform baseband functions in the RRU / AAU / RRH is referred to as a baseband low (BBL) unit.

[0066] 3 is a diagram of a system applicable to a connection method according to an embodiment of the present application. The system may be a system including multiple radio units connected in a direct connection method. For example, see FIG. 3. The data unit 121 is directly connected to the radio unit 111 and the radio unit 112 separately, and the data unit 111 communicates directly with the radio unit 112 through an interface (e.g., eCPRI).

[0067] Optionally, the system may alternatively be a system including multiple radio units connected in a cascade, or a system including multiple data units.

[0068] It should be understood that the above only describes some connection methods applicable to the embodiments of the present application, and the embodiments of the present application may be further applicable to other connection methods by which the wireless unit and the data unit can communicate with each other, which is not particularly limited in the present application.

[0069] Currently, the BBH and BBL use a negotiation mechanism to determine the splitting and deployment solutions for uplink and downlink data channels. We use the physical uplink shared channel (PUSCH) as an example. After eCPRI splitting, the physical deployments of different RUs are independent, and the BBLs of different RUs cannot form a resource pool. Therefore, the PUSCH channel specification for the BBL must be designed based on the peak specification requirements. However, in actual networks, the PUSCH channel load fluctuates greatly, resulting in high peak specifications and low average usage. As a result, if the peak value of the PUSCH channel on the BBL side is not reached, processing resources are wasted. The same problem exists for processing other channels, such as the physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), physical uplink control channel (PUCCH), and sounding reference signal (SRS), when they are deployed on the BBL.

[0070] Similar to the PUSCH channel, the SRS channel also has multiple alternative splitting solutions. As shown in Figure 4, SRS-Alternative 1 is used as an example. All uplink processing functions of the SRS channel are deployed on the BBL side. SRS-Alternative 4 is used as an example. The BBL side includes FFT / CP removal, while the BBH side includes digital beamforming (BF) (optional), channel estimation, and single-user (SU) weight calculation. In this case, most uplink processing functions of the SRS channel are deployed on the BBH side. Comparing SRS-Alternative 1 and SRS-Alternative 4, SRS-Alternative 1 has more functions deployed on the BBL side and consumes more BBL resources, while SRS-Alternative 4 has more functions deployed on the BBH side and consumes more BBH resources.

[0071] In a time division duplex (TDD) system, wireless communication performance depends on the measurement quality of the SRS channel. The SRS channel has an aging effect. Therefore, a shorter transmission period of the SRS channel usually means more timely and accurate measurement of the SRS channel and better wireless performance. However, a shorter SRS period also means a larger SRS specification and more processing resource consumption. In practical products, the SRS specification is limited due to limited processing resources. This limits the improvement of wireless performance in TDD systems.

[0072] In current technology, a negotiation mechanism is used between the BBH and BBL. When the system is started up, the partitioning and deployment solutions for the uplink and downlink channels (PUSCH / PDSCH / PDCCH / PUCCH / SRS) on the BBH and BBL are semi-statically determined. The SRS channel partitioning and deployment solution shown in Figure 4 is used as an example. Four SRS combs are configured on the air interface of a specific cell. After the BBH negotiates with the BBL, Comb 0 and Comb 1 are deployed on the BBL side (using SRS Alternative 1), and Comb 2 and Comb 3 are deployed on the BBH side (using SRS Alternative 4). However, as mentioned above, currently, the partitioning and deployment functions of the channels on the BBL and BBH are essentially independent of each other. In addition, the actual usage of some channels, such as the PUSCH on the BBL in a live network, is much less than the designed processing capacity, and the processing specifications for the SRS channel are usually limited. This limits the improvement of the wireless performance of TDD systems.

[0073] In view of the above reasons, the present application provides a communication method to support dynamic and flexible division and deployment of SRS channels, fully utilize the processing capabilities of the BBL side, achieve the effect of improving SRS channel specifications, and further improve wireless performance.

[0074] 5 is a schematic flowchart of an example of a wireless communication method according to an embodiment of the present application. The first communication device may be the above-mentioned BBH, or may be another device having corresponding functions and to be defined in the future. This is not particularly limited in the present application. The second communication device may be the above-mentioned BBL, or may be another device having corresponding functions and to be defined in the future. This is not particularly limited in the present application.

[0075] S510: A first communication device receives a first channel handling capability of a second communication device.

[0076] Correspondingly, the second communication device transmits the first channel handling capabilities of the second communication device.

[0077] The first channel processing capability includes an SRS channel processing capability.

[0078] Optionally, the first channel processing capability may further include one or more of a PDSCH channel processing capability, a PDCCH channel processing capability, a PUSCH channel processing capability, and a PUCCH channel processing capability.

[0079] S520: The first communication device receives a channel capability conversion rule.

[0080] Correspondingly, the second communication device transmits a channel capability conversion rule.

[0081] The channel capability conversion rule includes a conversion rule between an SRS channel capability and a non-SRS channel capability on a first channel, wherein the first channel includes at least an SRS channel and may further include one or more of a PDSCH channel, a PDCCH channel, a PUSCH channel, and a PUCCH channel.

[0082] In this embodiment of the present application, the second communication device can transmit its first channel handling capability and / or channel capability conversion rule to the first communication device in the form of eCPRI signaling during system restart or reconfiguration. The first channel handling capability and channel capability conversion rule of the second communication device can be carried in the same signaling for transmission, or can be carried in separate signaling for each transmission. The signaling for specifying the channel conversion rule can facilitate interconnection between DUs and RUs from different vendors, and also facilitate design separation between DUs and RUs for products from the same vendor.

[0083] S530: The second communication device processes the SRS based on the first SRS channel processing solution to obtain a first SRS channel processing result.

[0084] To take advantage of processing resource pooling and flexible evolution, the first SRS channel processing solution is a locally stored SRS processing solution, for example SRS-Alternative4.

[0085] Optionally, the second communication device may further process corresponding signals based on locally stored processing solutions of other channels, including but not limited to, a PDSCH channel, a PDCCH channel, a PUSCH channel, and a PUCCH channel, to obtain corresponding channel processing results, and the set of these channel processing results and the first SRS channel processing result may be referred to as a first channel processing result.

[0086] S540: The first communication device receives a first channel processing result including a first SRS channel processing result.

[0087] Correspondingly, the second communication device transmits the first channel processing result, which includes the first SRS channel processing result.

[0088] S550: The first communication device determines a second SRS channel processing solution based on the first SRS channel processing result.

[0089] Specifically, the first communication device can calculate a margin for the first channel processing capability of the second communication device based on the PDSCH channel processing results, PDCCH channel processing results, PUSCH channel processing results, PUCCH channel processing results, and SRS channel processing results for the current period and the first channel processing capability of the second communication device, and determine an SRS channel processing solution for the next period based on the margin for the first channel processing capability of the second communication device. For example, the PUSCH, PUCCH, and SRS channels are all uplink channels and have similar functional modules in algorithm processing. In addition, baseband processing in the industry usually has certain programmability. Therefore, specification exchange for the PUSCH, PUCCH, and SRS channels can be realized by design. Similarly, specification conversion can be performed by analyzing the difference in computational power between the PDSCH / PDCCH and SRS channels. Regarding the conversion rule, the conversion between the PUSCH specification and the SRS specification is used as an example. Let A be the total processing capacity of the PUSCH channel and the SRS channel, a1 be the consumption capacity of each basic processing unit of the PUSCH channel, b1 be the processing specification of the PUSCH channel, a2 be the consumption of each basic processing unit of the SRS channel, and b2 be the processing specification of the SRS channel. The system supports any combination of b1 and b2 as long as the following condition is met: a1 * b1 + a2 * b2 ≦ A. Therefore, this embodiment of the present application can implement dynamic and flexible SRS channel division and function deployment. To improve SRS processing capacity, the first communication device (BBH) can periodically collect statistics on the service status of channels and use conversion rules to convert the processing specification of another idle channel into the processing specification of the SRS channel.

[0090] The first channel processing result corresponds to the channel processing result in the current period, and the second SRS channel processing solution corresponds to the SRS channel processing solution in the next period, and the second SRS channel processing solution includes, but is not limited to, a splitting option (used to determine the SRS deployment function of the BBL side), a slot number of the SRS channel, a symbol of the SRS channel, a frequency domain position of the SRS channel, and combing information of the SRS channel.

[0091] S560: The first communication device transmits a second SRS channel processing solution.

[0092] Correspondingly, the second communication device receives the second SRS channel processing solution.

[0093] The first communication device can transmit the second SRS channel processing solution in the form of eCPRI signaling, and the second communication device receives the eCPRI signaling to obtain the second SRS channel processing solution accordingly.

[0094] Optionally, the notification frequency of eCPRI signaling may be determined based on the actual application scenario, and may be at the millisecond level or second level, which is not limited in this application.

[0095] S570: The second communication device processes the SRS based on the second SRS channel processing solution to obtain a second SRS channel processing result.

[0096] Specifically, after receiving the processing solution, the second communication device updates the channel configuration based on the second SRS channel processing solution, and when the SRS arrives, the second communication device completes SRS channel processing based on the updated channel configuration to obtain a second SRS channel processing result.

[0097] Optionally, the content included in the second SRS channel processing result is determined by the content of the current splitting option, and may include, for example, channel information, weight information, etc.

[0098] S580: The first communication device receives the second SRS channel processing result.

[0099] Correspondingly, the second communication device transmits the second SRS channel processing result.

[0100] The second communication device can send the second SRS channel processing result in the form of eCPRI signaling, and the first communication device receives the eCPRI signaling to obtain the second SRS channel processing result accordingly.

[0101] Optionally, the first communication device may further determine a third SRS channel processing solution based on the second SRS channel processing result. In this way, the processing solution in the next period can be continuously adjusted based on the processing result in the current period, so that the processing solution can be dynamically adjusted, thereby making full use of the idle processing resources on the BBL side, improving the processing specifications of the SRS channel, and further improving wireless performance.

[0102] During the operation process of a cell, if the load of the PUSCH, PDSCH, PDCCH, or PUCCH channel in the actual network does not reach the peak specification, according to the technical solution of the present application, the processing capacity of another idle channel on the BBL is used to process the SRS channel, so that the idle processing resources on the BBL side are fully utilized, the processing specification of the SRS channel is improved, and the wireless performance is further improved.

Thus, all references to embodiments in this specification do not necessarily refer to the same embodiment. In addition, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0134] It should be further understood that ordinal numbers such as "first" and "second" in the embodiments of the present application are used to distinguish between multiple objects, but are not intended to limit the size, content, order, chronological order, priority, importance, etc. of the multiple objects. For example, first information and second information do not indicate a difference in the amount, content, priority, importance, etc. of the information.

[0135] It should be further understood that in this application, both "when" and "if" mean that the network element will perform the corresponding processing in the intended situation, but do not limit the time, require the network element to have the action determined during implementation, or imply any other limitation.

[0136] It should be further understood that, in this application, "at least one" means one or more, and "plurality" means two or more. "At least one of the items (portions)" or similar expressions refers to one item (portion) or multiple items (portions), i.e., any combination of these items, including any combination of singular items (portions) or multiple items (portions).

[0138] It should be further understood that the term "and / or" in this application describes only the relational relationship between related objects and indicates that three relationships may exist. For example, A and / or B can represent the following cases: A exists alone, A and B both exist, and B exists alone, and A and B may be singular or plural. The character " / " generally indicates an "or" relationship between related objects. For example, A / B indicates A or B.

[0139] It should be further understood that in the embodiments of the present application, "B corresponding to A" means that B is associated with A and B can be determined based on A. However, it should be further understood that determining B based on A does not mean that B is determined based only on A. B can instead be determined based on A and / or other information.
