Description

[Technical field]

[0001] The present disclosure relates to the field of wireless communication, and more particularly, to a communication method and device. [Background technology]

[0002] The areas currently being researched for Wi-Fi technology include 320MHz bandwidth transmission, multi-band aggregation and cooperation, and are expected to increase speed and throughput by at least four times compared to existing standards. Its main application scenarios include video transmission, AR (Augmented Reality), VR (Virtual Reality), etc.

[0003] Multi-band aggregation and cooperation refers to devices communicating simultaneously in the 2.4GHz, 5GHz and 6GHz frequency bands. To communicate simultaneously in multiple bands between devices, new media access control (MAC) mechanisms need to be defined and managed. It is also expected that multi-band aggregation and cooperation can support low latency transmission.

[0004] Currently, the maximum bandwidth supported by multi-band aggregation and system technology is 320 MHz (160 MHz+160 MHz), with the possibility of supporting 240 MHz (160 MHz+80 MHz) and other bandwidths. Current technology can use single-type resource units or composite resource units for data transmission.

[0005] In addition, communication systems usually use a multi-user multiple-input multiple-output (MU-MIMO) mechanism to increase spectrum utilization. However, in the conventional technology, the identification of the capability information of MU-MIMO needs to be enhanced because it only supports a single type resource unit and does not support a composite resource unit.

[0019] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as understood by one of ordinary skill in the art to which this disclosure belongs.

[0020] FIG. 1 is an exemplary diagram of a wireless communication scene.

[0021] In a wireless local area network, a Basic Service Set (BSS) can consist of an Access Point (AP) and one or more non-APs (also called Stations (STAs)) that communicate with the AP. A Basic Service Set can connect to a Distribution System (DS) via an AP device, and then access another Basic Service Set to form an Extended Service Set (ESS).

[0022] AP is a wireless switch for wireless networks and is the core of wireless networks. APs can be used as wireless base stations and are mainly used as bridges that connect wireless networks to wired networks. By using such APs, wired and wireless networks can be integrated.

[0023] As an example, an AP may include software applications and / or circuits to allow other types of nodes in a wireless network to communicate with the outside and inside of the wireless network through the AP. For example, an AP may be a terminal device or a network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0024] By way of example, a station (STA) may include, but is not limited to, a cellular phone, a smart phone, a wearable device, a computer, a personal digital assistant (PDA), a personal communication system (PCS) device, a personal information manager (PIM), a personal navigation device (PND), a global location system, a multimedia device, an Internet of Things (IoT) device, and the like.

[0025] Although FIG. 1 shows one AP communicating with three stations (STA1, STA2, STA3), this is merely an example and embodiments of the present disclosure are not limited thereto, for example, the APs and STAs can have any number and / or type.

[0026] In an exemplary embodiment of the present disclosure, the AP and the station STA (STA1, STA2, STA3 shown in FIG. 1) may be multi-link devices (MLDs), and may be represented as AP MLD and non-AP STA MLD, respectively. That is, the AP MLD may represent an access point supporting a multi-link communication function, and the non-AP STA MLD may represent a station supporting a multi-link communication function. That is, the AP MLD and the non-AP STA MLD may support a function of simultaneously transmitting and / or receiving on a multi-link at the same time. For example, there may be multiple connections at different frequencies between the AP MLD and the non-AP STA MLD, such as connections at 2.4 GHz, 5 GHz, and 6 GHz, or several same or different bandwidth connections under 2.4 GHz, 5 GHz, and 6 GHz. There may also be multiple channels under each connection. The communication method and communication device provided by the embodiment of the present disclosure may be applied to communication between the AP MLD and the non-AP STA MLD, that is, to a multi-link communication environment.

[0027] 2 is a flowchart of a communication method according to an embodiment. The communication method shown in FIG. 2 can be applied to a multi-link communication environment. Specifically, the communication method shown in FIG. 2 can be applied to a transmitting side, which can be a communication device that can support multi-link, such as AP MLD or non-AP STA MLD. However, the present disclosure is not limited thereto, and for example, the communication method shown in FIG. 2 can be applied to a single-connection communication environment.

[0028] Referring to Fig. 2, in step 210, a first message frame can be determined, where the first message frame can include information about multi-user multiple input / output (MU-MIMO), in which the information about MU-MIMO can be used to identify a communication device's support for a single-type resource unit and a composite resource unit.

[0029] According to an embodiment, when the communication method shown in FIG. 2 is applied to an access point (e.g., AP MLD), the first message frame may be a beacon frame, a probe response frame, an association response frame, or a re-association response frame. Also, when the communication method shown in FIG. 2 is applied to a station (e.g., non-AP STA MLD), the first message frame may be a probe request frame, an association request frame, or a re-association request frame. However, the above embodiment of the first message frame is merely illustrative and is not a limitation of the present disclosure, and any other type of frame is also possible.

[0030] In the embodiment of the present disclosure, the method of determining the first message frame may be various, for example, the first message frame may be generated based on at least one of the network conditions, the load conditions, the hardware capabilities of the transmitting / receiving device, the traffic type, and the related protocol definition, and the embodiment of the present disclosure is not particularly limited. In the embodiment of the present disclosure, the first message frame may be obtained from an external device, and the embodiment of the present disclosure is not particularly limited.

[0031] According to an embodiment of the present disclosure, the first message frame may carry information about MU-MIMO in the form of an information element. For example, the information about MU-MIMO may be realized using a physical layer (PHY) capability information domain of an extreme high-throughput (EHT) capability information element. The information about MU-MIMO will then be described in detail with reference to Tables 1 and 2.

[0032] In step 220, a first message frame can be transmitted. In a multi-link communication environment, a transmitter can transmit the first message frame under any connection of multiple connections to inform a receiver of its MU-MIMO capability information.

[0033] As an example, the EHT capability information element may have the format shown in Table 1 below.

[0034] [Table 1]

[0035] In Table 1, an element ID is set to a specific value to identify an EHT capability information element, a length represents the length information of the EHT capability information element, and an EHT PHY capability information domain can include information on MU-MIMO. In addition, the EHT capability information elements shown in Table 1 are merely examples, and the present disclosure is not limited thereto. For example, the EHT capability information element in Table 1 can further include an element ID extension domain, an EHT MAC capability information domain, a supported ETH-MCS and NSS aggregation domain, etc.

[0036] The EHT PHY capability information domain may have multiple bytes (octets), for example, but not limited to, 11 bytes. Each bit in the multiple bytes of the EHT PHY capability information domain may represent a different sub-domain and is used to carry different capability information. According to an embodiment of the present disclosure, information about MU-MIMO may be represented using bits in the EHT PHY capability information domain. For example, as shown in Table 2, information about MU-MIMO may be represented using a partial bandwidth DL MU-MIMO sub-domain and / or a partial bandwidth UL MU-MIMO sub-domain in the EHT PHY capability information domain.

[0037] In other words, the information about MU-MIMO in the first message frame may include partial bandwidth downlink MU-MIMO information and / or partial bandwidth uplink MU-MIMO information, as shown in Table 2 below.

[0038] [Table 2]

[0039] Referring to Table 2, for downlink transmission, the support status of single type resource units and / or composite resource units can be identified using partial bandwidth downlink MU-MIMO sub-domain, and for uplink transmission, the support status of single type resource units and / or composite resource units can be identified using partial bandwidth uplink MU-MIMO sub-domain, in which the single type resource and / or composite resource unit does not occupy the entire operation bandwidth, for example, in a 20MHz bandwidth, the single type resource used may be 52-tone, and the composite type resource may be 106+26-tone. In other words, the partial bandwidth downlink MU-MIMO information (partial bandwidth DL MU-MIMO in Table 2) can be used to identify that the communication device supports downlink communication using single type resource units and / or composite resource units, and the partial bandwidth uplink MU-MIMO information (partial bandwidth UL MU-MIMO in Table 2) can be used to identify that the communication device supports uplink communication using single type resource units and / or composite resource units.

[0040] In the embodiments of the present disclosure, a single-type resource unit may refer to a resource unit including only a specific number of subcarriers (tones), for example, the single-type resource unit may be 26-tone, 52-tone, 106-tone, 242-tone, 484-tone, 996-tone, 2*996-tone, or 4*996-tone. According to the embodiments, a composite resource unit may be composed of a single-type resource unit. In one embodiment, a composite resource unit may be composed of two specific single-type resource units and may be related to a bandwidth. For example, a composite resource unit may include at least a first single-type resource unit and a second single-type resource unit, in which the first single-type resource unit and the second single-type resource unit have different numbers of subcarriers (tones). Also, the composite resource unit may be composed of at least two different kinds of single-type resource units, such as 52+26-tone, 106+26-tone, 484+242-tone, 996+484-tone, 996+484+242-tone, 3×996-tone, etc. However, the present disclosure is not limited thereto, and the composite resource unit may further include 2×996+484-tone, 3×996+484-tone, etc.

[0041] The identification of MU-MIMO capability information provided by the embodiments of the present disclosure can not only support a single type resource unit, but also support composite resource units, thereby improving system throughput.

[0042] In one embodiment of the present disclosure, the communication method shown in FIG. 2 can be applied to a station that supports multilink (e.g., non-AP STA MLD). In this case, the partial bandwidth downlink MU-MIMO information (partial bandwidth DL MU-MIMO subdomain shown in Table 2) can be used to identify that the station supports downlink communication using single type resource units and / or composite resource units in the supported bandwidth. For example, the partial bandwidth downlink MU-MIMO (partial bandwidth DL MU-MIMO) subdomain in Table 2, when set to a first specific value (e.g., "1"), can indicate that the station supports receiving protocol data units (PPDUs) with single type resource units and / or composite resource units in the supported bandwidth. According to an embodiment, the single type resource units and / or composite resource units do not occupy the entire supported bandwidth. For example, the partial bandwidth downlink MU-MIMO information can identify that the station can support transmission to receive downlink MU-MIMO 26-tone in a 20 MHz bandwidth, and can also support transmission of 106+26-tone.

[0043] When the communication method shown in FIG. 2 is applicable to a station (e.g., non-AP STA MLD) supporting multi-link, the communication method shown in FIG. 2 may further include a step of receiving a protocol data unit (PPDU) using a single type resource unit or a composite resource unit (not shown). According to an embodiment, a signaling field (e.g., U-SIG part) of the protocol data unit (PPDU) may include a station identification bit (STA-ID) and a single type resource unit or composite resource unit number (RU / MRU number). For example, the station identification bit (STA-ID) may be used to represent an address of the non-AP STA MLD, or may represent an address of an attached STA corresponding to a connection of the non-AP STA MLD. For example, the station identification bit may be an association identifier (AID). For example, the single type resource unit or composite resource unit number (RU / MRU number) may be used to represent an RU / MRU number in a corresponding bandwidth.

[0044] When the communication method shown in FIG. 2 is applicable to a station supporting multilink (e.g., non-AP STA MLD), the partial bandwidth uplink MU-MIMO information (partial bandwidth UL MU-MIMO sub-domain shown in Table 2) can be used to identify that the station supports transmitting trigger-based MU-MIMO transmission using single type resource units and / or composite resource units. For example, it can be identified that the station supports transmitting EHT TB PPDU with single type resource units and / or composite resource units in the supported bandwidth via the partial bandwidth uplink MU-MIMO information. According to an embodiment, the single type resource and / or composite resource units used when the station transmits the EHT TB PPDU do not occupy the entire supported bandwidth.

[0045] In another embodiment of the present disclosure, the communication method shown in FIG. 2 can be applied to an access point that supports multilink (e.g., AP MLD). In this case, the partial bandwidth uplink MU-MIMO information (partial bandwidth UL MU-MIMO sub-domain shown in Table 2) can be used to identify that the access point supports receiving trigger-based MU-MIMO transmission using single type resource units and / or composite resource units. For example, it can be identified that the access point supports receiving UL MU-MIMO transmission of TB in a certain bandwidth (e.g., receiving EHT TB PPDU) via the partial bandwidth uplink MU-MIMO information. According to the embodiment, the single type resource and / or composite resource unit used when the access point receives the EHT TB PPDU does not occupy the entire supported bandwidth.

[0046] According to an embodiment of the present disclosure, in the EHT capability information element, specifically, the partial bandwidth DL MU-MIMO sub-domain and the partial bandwidth UL MU-MIMO sub-domain carried in the PHY capability information domain can identify the status of single type resource unit (RU) or multiple resource unit (MRU) supported by the device, specifically, The partial bandwidth DL MU-MIMO sub-domain is used to identify non-AP STAs that support receiving downlink RU / MRU communication in the supported bandwidth by MLD. For example, a station can support receiving downlink MU-MIMO 26-tone transmission in a 20MHz bandwidth, and can also support 106+26-tone transmission. In the received PPDU format, the signaling field (e.g. U-SIG) part is the STA-ID+RU / MRU number; The partial bandwidth UL MU-MIMO sub-domain: for AP MLD, it identifies that UL MU-MIMO transmission is supported to receive TB (trigger-based) in a certain bandwidth, where the transmission resource used may be RU or MRU, for example, in a 20 MHz bandwidth, it may be 26-tone RU or 106+26-tone MRU; for non-AP STA MLD, it identifies that UL MU-MIMO transmission is supported to send TB, where the transmission resource used may be RU or MRU.

[0047] Although the examples in this specification describe single-type resource units and composite resource units in a 20 MHz bandwidth, it should be understood that the present disclosure is not limited thereto and that various resource units in other bandwidths are also within the scope of the present disclosure.

[0048] According to an embodiment, the composite resource units identified and supported in the partial bandwidth DL MU-MIMO sub-domain and the partial bandwidth UL MU-MIMO sub-domain are at least one of 52+26-tone, 106+26-tone, 484+242-tone, 996+484-tone, 996+484+242-tone, and 3×996-tone. According to an embodiment, all the above composite resource units are identified in the partial bandwidth DL MU-MIMO sub-domain and the partial bandwidth UL MU-MIMO sub-domain, or partial composite resource units therein are supported. However, the composite resource units shown here are merely illustrative examples rather than present in the present disclosure, and composite resource units of other sizes are also within the scope of the present disclosure.

[0049] 3 is a flowchart of a communication method of an embodiment. The communication method shown in FIG. 3 can be applied to a receiving side in a multi-link communication environment, and the receiving side can be a communication device that can support multi-link. For example, the sending side can be an AP MLD and the receiving side can be a non-AP STA MLD, or the sending side can be a non-AP STA MLD and the receiving side can be an AP MLD. However, the present disclosure is not limited thereto, and for example, the communication method shown in FIG. 3 can be applied to a single-connection communication environment.

[0050] 3, in step 310, a first message frame is received from a communication device (i.e., a transmitting side) that supports multi-link. Specifically, in step 310, the receiving side can receive a first message frame from a transmitting side (i.e., a communication device that supports multi-link in step 310). According to an embodiment, the first message frame can include information about Multi-User Multiple Input / Output (MU-MIMO), in which the information about MU-MIMO can be used to identify the support status of the communication device for the single-type resource unit and the composite resource unit.

[0051] According to an embodiment, the information about MU-MIMO may include partial bandwidth downlink MU-MIMO information. If the communication device in step 310 is a station supporting multilink, the partial bandwidth downlink MU-MIMO information is used to identify that the station supports downlink communication using single type resource units and / or composite resource units in the supported bandwidth.

[0052] According to an embodiment, the information regarding MU-MIMO may include partial bandwidth uplink MU-MIMO information, which is used to identify that the communication device supports uplink communication using single type resource units and / or composite resource units.

[0053] According to an embodiment, if the communication device is a station supporting multilink, the partial bandwidth uplink MU-MIMO information is used to identify that the station can support transmitting trigger-based MU-MIMO transmission using single type resource units and / or composite resource units.

[0054] According to an embodiment, if the communication device is an access point supporting multilink, the partial bandwidth uplink MU-MIMO information is used to identify that the access point supports receiving trigger-based MU-MIMO transmission using single type resource units and / or composite resource units.

[0055] According to an embodiment, the composite resource unit is at least one of 52+26-tone, 106+26-tone, 484+242-tone, 996+484-tone, 996+484+242-tone, 3×996-tone.

[0056] The first message frame, information related to MU-MIMO, partial bandwidth uplink MU-MIMO information, partial bandwidth downlink MU-MIMO information, single type resource unit, and composite resource unit in step 310 are similar to the embodiment described with reference to FIG. 2 and Tables 1 and 2, and for the sake of brevity, duplicated description will be omitted here.

[0057] In step 320, a communication operation can be performed based on the first message frame. The receiving side can know the MU-MIMO capability information of the transmitting side through the first message frame, and can select an appropriate resource for communication based on the known capability information.

[0058] It should be understood that the communication method illustrated in Fig. 3 is merely an example and is not a limitation of the present disclosure. For example, the communication method illustrated in Fig. 3 may further include receiving a protocol data unit (PPDU) using a single type resource unit or a composite resource unit if the communication device in step 310 is a station supporting multilink. According to an embodiment, a signaling field of the received protocol data unit (PPDU) may include an identification bit of the station and a number of the single type resource unit or the composite resource unit.
