Description

Wireless communication method and device Technical Field

[0001] The present application relates to the field of communications, and more particularly, to a method and apparatus for wireless communications. Background Art

[0002] With the advancement of communication technology, data units (DUs) and radio units (RUs) can be located in different locations to improve network coverage and jointly provide services to users. When the enhanced common public radio interface (eCPRI) connects the DU and RU, it splits the gNodeB's baseband processing into two parts: the baseband high (BBH) processing unit on the DU side, known as the baseband unit (BBU), and the baseband low (BBL) processing unit on the RU side, known as the active antenna unit (AAU).

[0003] In current technology, the BBH and BBL semi-statically determine the division and deployment of uplink and downlink channels on the BBH and BBL through a negotiation mechanism at system startup. However, the division and functional deployment of each channel on the BBL and BBH are largely independent of each other. In existing networks, the actual utilization of some channels on the BBL is far below the designed processing capacity, while the processing specifications of other channels are often limited, hindering the performance of wireless communication systems.

[0004] Therefore, there is an urgent need for a communication method that can support dynamic and flexible segmentation and deployment of channels, fully utilize the processing capabilities of the BBL side, and improve the performance of wireless communication.

[0056] The technical solution in this application will be described below with reference to the accompanying drawings.

[0057] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as long term evolution (LTE) systems, frequency division duplex (FDD) systems, time division duplex (TDD) systems, fifth generation (5G) systems or new radio (NR), sixth generation (6G) systems or future communication systems. The 5G mobile communication system described in this application includes a non-standalone (NSA) 5G mobile communication system or a standalone (SA) 5G mobile communication system. The communication system can also 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 other communication systems.

[0058] In addition, the network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0059] To facilitate understanding of the embodiment of the present application, an application scenario of the embodiment of the present application is first described in detail with reference to FIG1 .

[0060] Figure 1 is a schematic structural diagram of a communication system applicable to an embodiment of the present application. First, the devices that may be involved in the communication system are described.

[0061] Radio Unit (RU) 110: The RU 110 can perform functions such as intermediate frequency (IF) signal processing, RF signal processing, and duplexing. For example, the RU 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 elements or communication devices capable of processing IF signals, RF signals, or IF / RF signals.

[0062] Data unit (DU) 120: The data unit 120 can implement baseband signal processing functions. For example, the data unit 120 can be a baseband unit (BBU), a centralized control unit (CU), a distributed control unit (DU), an open baseband unit (O-distributed unit, O-DU) in O-RAN, or other network elements or communication devices with baseband signal processing capabilities. The module used for baseband processing in the data unit 120 can be called a baseband board, and the number of baseband boards can be one or more.

[0063] The communication interface between the data unit 120 and the radio frequency unit 110 can be called a fronthaul interface. For example, the fronthaul interface can be a common public radio interface (CPRI), an enhanced common public radio interface (eCPRI) interface, or other interfaces defined in the future for connecting the data unit 120 and the radio frequency unit 110. This application does not specifically limit this.

[0064] CPRI is a key communication interface specification commonly used between radio equipment control (REC) and radio equipment (RE) in cellular wireless networks. The CPRI interface rate is proportional to the number of antennas and carrier bandwidth. As the number of antennas and bandwidth in NR networks increases, the rate requirements for the CPRI interface are also increasing, significantly increasing transmission costs. Because data transmitted on the communication protocol stack increases layer by layer, the amount of data increases as it goes down. Therefore, the eCPRI interface was introduced. This allows data processing at the upper physical layer to be performed at the BBU, while processing data at the lower layers is performed at the RRU, thereby reducing the transmission rate requirements.

[0065] When the eCPRI interface is used to connect the DU and RU, the eCPRI interface divides the baseband processing of the gNodeB into two parts: the baseband processing unit (BBH) on the DU side is called the BBU, and the baseband processing unit (BBL) on the RU side is called the AAU.

[0066] Different interfaces may adopt different functional division methods. The following uses an O-RAN system applicable to an embodiment of the present application as an example to illustrate different interfaces.

[0067] FIG2 shows a system diagram of an access network. The access network equipment includes one or more functional modules for implementing signal processing. As shown in FIG2 , taking the physical layer function as an example, the access network equipment includes one or more of the following functions: coding, rate matching, scrambling, modulation, layer mapping, precoding, resource element (RE) mapping, digital beamforming (BF), inverse fast Fourier transform (IFFT) / cyclic prefix (CP) addition, decoding, rate matching removal, descrambling, demodulation, inverse discrete Fourier transform (IDFT), channel equalization (or channel estimation), RE mapping removal, digital BF, fast Fourier transform (FFT) / CP removal, digital to analog (DA) conversion, analog BF (uplink), analog to digital (AD) conversion, or analog BF (downlink).

[0068] The above-mentioned one or more functional modules can be implemented by software, hardware, or a combination of software and hardware. They can be physically discrete or integrated. It is understood that the above-mentioned functional modules are merely examples. The access network device may include more other modules (for example, 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) according to the design, or may not include a functional module shown in Figure 2 (for example, not including a digital BF module). The access network device also includes a fronthaul (FH) interface between the DU and the RU for implementing 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 and the RU is located in the RRU / AAU / RRH. The interface between the BBU and the RRU / AAU / RRH may also be called a fronthaul interface. To implement the fronthaul interface, the BBU and the RRU / AAU / RRH may be connected via a fronthaul network, or the DU and the RU may be connected via a fronthaul network. For example, fronthaul networks include but are not limited to: fiber direct connection and wavelength division network.

[0069] The access network equipment can support one or more types of fronthaul interfaces, and different fronthaul interfaces correspond to DUs and RUs with different functions. As shown in Figure 2, if the fronthaul interface between the DU and the RU is CPRI, the DU is configured to implement one or more baseband functions, and the RU is configured to implement one or more RF functions. If the fronthaul interface between the DU and the RU is eCPRI, relative to CPRI, part of the downlink and / or uplink baseband functions are moved from the DU to the RU for implementation. The division method between the DU and the RU is different, corresponding to different types (category, referred to as Cat) of eCPRI. Figure 2 gives six examples of eCPRI, represented by Cat A, B, C, D, E, and F (can also be represented as Option A to F, or Option 1 to 6, or other methods). It can be understood that there may be other division methods between the DU and the RU, that is, there may be other types of eCPRI.

[0070] Taking eCPRI Cat A as an example, for downlink transmission, based on layer mapping, the DU is configured to implement layer mapping and one or more functions preceding it (i.e., one or more of coding, rate matching, scrambling, modulation, and layer mapping), while other functions after layer mapping (e.g., RE mapping, digital BF, or one or more of IFFT / CP addition) are moved to the RU for implementation. For uplink transmission, based on RE demapping, the DU is configured to implement demapping and one or more functions preceding it (i.e., one or more of decoding, derate matching, descrambling, demodulation, IDFT, channel equalization, and RE demapping), while other functions after demapping (e.g., one or more of digital BF or FFT / CP removal) are moved to the RU for implementation.

[0071] Similarly, eCPRI Cat B, Cat C, Cat D, Cat E, and Cat F correspond to different DU and RU segmentation methods, respectively. The segmentation point and the functions before the segmentation point are implemented by the DU, while the functions after the segmentation point are implemented by the RU. The segmentation points of each type of eCPRI are shown in Figure 2 and will not be described in detail. For example, for eCPRI Cat B, RE mapping is used as the segmentation for downlink transmission, and de-RE mapping is used as the segmentation for uplink transmission. For uplink transmission, RE mapping and the functions before RE mapping are implemented by the DU, while the functions after RE mapping and the RF functions are implemented by the RU. For downlink transmission, de-RE mapping and the functions before de-RE mapping are implemented by the DU, while the functions after de-RE mapping and the RF functions are implemented by the RU.

[0072] The eCPRI segmentation scheme can be symmetrical for uplink and downlink, as shown in Figure 2 for eCPRI Category B and Category C. Alternatively, the eCPRI segmentation scheme can be asymmetrical for uplink and downlink, as shown in Figure 2 for eCPRI Category A, Category D, Category E, and Category F. This is not a limitation. Optionally, different segmentation schemes can be configured for different channels or different channel groups for uplink and / or downlink, i.e., different types of eCPRI can be configured. A channel group can include one or more channels.

[0073] In one possible design, the DU is located in the BBU and the RU is located in the RRU / AAU / RRH. The processing unit in the BBU used to implement the baseband function is called the baseband high layer (BBH) unit, and the processing unit in the RRU / AAU / RRH used to implement the baseband function is called the baseband low layer (BBL) unit.

[0074] FIG3 is a schematic diagram of a system for a connection method applicable to an embodiment of the present application. The system may include multiple RF units connected in a direct connection manner. For example, referring to FIG3 , data unit 121 is directly connected to RF unit 111 and RF unit 112, respectively, and data unit 111 and RF unit 112 communicate directly with each other via an interface (e.g., an ECPRI interface).

[0075] Optionally, the system may also be a system including multiple radio frequency units connected in a cascaded manner or a system including multiple data units.

[0076] It should be understood that the above is only an illustration of several connection methods applicable to the embodiments of the present application. The embodiments of the present application can also be applied to other connection methods in which the radio frequency unit and the data unit can communicate, and the present application does not specifically limit this.

[0077] Currently, the BBH and BBL use a negotiation mechanism to determine the division and deployment of uplink and downlink data channels. Taking the physical uplink shared channel (PUSCH) as an example, after eCPRI division, due to the independent physical deployment of different RUs, the BBLs of different RUs cannot form a resource pool. Therefore, the BBL's PUSCH channel specifications must be designed according to peak requirements. However, in actual networks, PUSCH channel load fluctuates greatly, with high peak specifications and low average utilization. As a result, processing resources are wasted on the BBL side when the PUSCH channel peak is not reached. The same problem also exists when 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), are deployed on the BBL.

[0078] Similar to the PUSCH channel, the SRS channel also has various splitting options. As shown in Figure 4, taking SRS-Alternative 1 as an example, all uplink processing functions of the SRS channel are deployed on the BBL side. Taking SRS-Alternative 4 as an example, the BBL side includes FFT / CP removal, and the BBH side includes digital beamforming (BF) (optional), channel estimation, and single-user (SU) weight calculation. In this case, most of the uplink processing functions of the SRS channel are deployed on the BBH side. Comparing SRS-Alternative 1 and SRS-Alternative 4, SRS-Alternative 1 deploys more functions on the BBL side, consuming more BBL resources; SRS-Alternative 4 deploys more functions on the BBH side, consuming more BBH resources.

[0079] In time division duplexing (TDD) systems, wireless communication performance depends on the quality of SRS channel measurements. Due to the aging effect of SRS channels, shorter SRS channel transmission periods generally result in more timely and accurate SRS channel measurements, leading to better wireless performance. However, shorter SRS periods also mean larger SRS specifications and increased processing resource consumption. In actual products, SRS specifications are often restricted due to limited processing resources, which hinders improvements in TDD system wireless performance.

[0080] In current technology, the BBH and BBL semi-statically determine the division and deployment of uplink and downlink channels (PUSCH / PDSCH / PDCCH / PUCCH / SRS) on the BBH and BBL through a negotiation mechanism at system startup. Taking the SRS channel division and deployment scheme shown in Figure 4 as an example, a cell's air interface is configured with four SRS combs. After negotiation between the BBH and BBL, combs 0 and 1 are deployed on the BBL side (using SRS-Alternative 1), while combs 2 and 3 are deployed on the BBH side (using SRS-Alternative 4). However, as mentioned above, the division and functional deployment of each channel on the BBL and BBH are currently largely independent. In existing networks, the utilization of certain channels, such as PUSCH, on the BBL is far below the designed processing capacity. Furthermore, the processing specifications of the SRS channel are often limited, hindering the improvement of TDD system wireless performance.

[0081] Based on the above reasons, this application proposes a communication method that can support dynamic and flexible segmentation and deployment of SRS channels, fully utilize the processing capabilities of the BBL side, achieve the effect of improving the SRS channel specifications, and further improve wireless performance.

[0082] FIG5 is a flow chart illustrating an example wireless communication method according to an embodiment of the present application. The first communication device may be the BBH described above, or other devices with corresponding functions defined in the future, which are not specifically limited in this application. The second communication device may be the BBL described above, or other devices with corresponding functions defined in the future, which are not specifically limited in this application.

[0083] S510: A first communication device receives a first channel processing capability of a second communication device.

[0084] Correspondingly, the second communication device sends the first channel processing capability of the second communication device.

[0085] The first channel processing capability includes an SRS channel processing capability.

[0086] Optionally, the first channel processing capability may also include one or more of PDSCH channel processing capability, PDCCH channel processing capability, PUSCH channel processing capability, and PUCCH channel processing capability.

[0087] S520: The first communication device receives a channel capability conversion rule.

[0088] Correspondingly, the second communication device sends a channel capability conversion rule.

[0089] The channel capability conversion rule includes a conversion rule between SRS channel capability and non-SRS channel capability in the first channel. The first channel includes at least an SRS channel and may also include one or more of a PDSCH channel, a PDCCH channel, a PUSCH channel, and a PUCCH channel.

[0090] In an embodiment of the present application, the second communication device sends the first channel processing capability and / or channel capability conversion rule of the second communication device to the first communication device, which can be sent in the form of eCPRI interface signaling when the system is restarted or reconfigured. Among them, the first channel processing capability and channel capability conversion rule of the second communication device can be carried in the same signaling and sent, or they can be carried in different signaling and sent separately. The signaling that defines the channel conversion rule can facilitate the interconnection of DUs and RUs between different manufacturers, and products from the same manufacturer are also conducive to the decoupling of the design between DUs and RUs.

[0091] S530: The second communication device processes the SRS signal according to the first SRS channel processing scheme to obtain a first SRS channel processing result.

[0092] The first SRS channel processing solution is a locally stored SRS processing solution, such as SRS-Alternative 4, to obtain advantages of processing resource pooling and flexible evolution.

[0093] Optionally, the second communication device may further process the corresponding signal according to other locally stored channel processing schemes, including but not limited to the PDSCH channel, the PDCCH channel, the PUSCH channel, and the PUCCH channel, to obtain corresponding channel processing results. The set of these channel processing results and the first SRS channel processing result may be referred to as the first channel processing result.

[0094] S540: The first communication device receives a first channel processing result, including a first SRS channel processing result.

[0095] Correspondingly, the second communication device sends the first channel processing result, including the first SRS channel processing result.

[0096] S550: The first communication device determines a second SRS channel processing scheme according to the first SRS channel processing result.

[0097] Specifically, the first communication device can calculate the margin of 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 in the current cycle, as well as the first channel processing capability of the second communication device, and thereby determine the SRS channel processing scheme for the next cycle based on the margin of the first channel processing capability of the second communication device. For example, since the PUSCH, PUCCH, and SRS channels are all uplink channels, they have similar functional modules in algorithm processing, and the industry's baseband processing generally has a certain degree of programmability. Therefore, it is feasible to interchange the specifications of the PUSCH, PUCCH, and SRS channels in terms of design. Similarly, the difference in computing power between the downlink channels PDSCH / PDCCH and SRS channels can be analyzed to convert the specifications. The conversion rule takes the conversion of PUSCH and SRS specifications as an example. Assuming that the total processing capacity of the PUSCH channel and the SRS channel is A, the consumption capacity of each PUSCH channel basic processing unit is a1, and the PUSCH channel processing specification is b1; the consumption of each SRS channel basic processing unit is a2, and the SRS channel processing specification is b2; as long as the condition is met: a1*b1+a2*b2<=A, the system supports any combination of b1 and b2. Therefore, the embodiment of the present application can realize dynamic and flexible segmentation and functional deployment of the SRS channel. The first communication device (BBH) can periodically count the business conditions of each channel and convert the idle channel processing specifications of other channels into SRS channel processing specifications through the conversion rules to improve the SRS processing capability.

[0098] The first channel processing result corresponds to the channel processing result in the current cycle, and the second SRS channel processing scheme corresponds to the SRS channel processing scheme in the next cycle. The second SRS channel processing scheme includes but is not limited to a slicing option (used to determine the SRS deployment function on the BBL side), the time slot number of the SRS channel, the symbol of the SRS channel, the frequency domain position of the SRS channel, and the combing information of the SRS channel.

[0099] S560: The first communication device sends a second SRS channel processing solution.

[0100] Correspondingly, the second communication device receives the second SRS channel processing solution.

[0101] The first communication device may send the second SRS channel processing solution in the form of eCPRI interface signaling, and correspondingly, the second communication device receives the eCPRI interface signaling to obtain the second SRS channel processing solution.

[0102] Optionally, the notification frequency of the eCPRI interface signaling may be determined by the actual application scenario, which may be in milliseconds or seconds, and is not limited in this application.

[0103] S570: The second communication device processes the SRS signal according to the second SRS channel processing scheme to obtain a second SRS channel processing result.

[0104] Specifically, after receiving the second SRS channel processing solution, the second communication device updates the channel configuration according to the processing solution. When the SRS signal arrives, the second communication device completes the SRS channel processing according to the updated channel configuration and obtains the second SRS channel processing result.

[0105] Optionally, the content included in the second SRS channel processing result is determined by the content of the current segmentation option, for example, it may include channel information, weight information, etc.

[0106] S580: The first communication device receives a second SRS channel processing result.

[0107] Correspondingly, the second communication device sends a second SRS channel processing result.

[0108] The second communication device may send the second SRS channel processing result in the form of eCPRI interface signaling. Correspondingly, the first communication device receives the eCPRI interface signaling to obtain the second SRS channel processing result.

[0109] Optionally, the first communication device can also determine the third SRS channel processing scheme based on the second SRS channel processing result. In this way, the processing scheme for the next cycle can be continuously adjusted according to the processing result of the current cycle, and dynamic adjustment of the processing scheme can be achieved, thereby making full use of the idle processing resources on the BBL side, improving the processing specifications of the SRS channel, and further improving the wireless performance.

[0110] During cell operation, when the load of PUSCH, PDSCH, PDCCH, and PUCCH channels in the actual network does not reach the peak specifications, the technical solution of the present application can use the idle channel processing capabilities of the BBL to process the SRS channel, thereby making full use of the idle processing resources on the BBL side, improving the processing specifications of the SRS channel, and further improving the wireless performance.
