Description

Communication method, electronic device, and storage medium

Technical Field

The embodiment of the disclosure relates to the technical field of mobile communication, in particular to a communication method, electronic equipment and a storage medium.

Background

With the rapid development of mobile communication technology, wireless fidelity (WIRELESS FIDELITY, wi-Fi) technology has made great progress in terms of transmission rate, throughput, and the like. Currently, wi-Fi technology is researched, for example, 320Mhz bandwidth transmission, aggregation and collaboration of multiple frequency bands, and the like, and the main application scenarios of the Wi-Fi technology are video transmission, augmented Reality (Augmented Reality, AR), virtual Reality (VR), and the like.

Specifically, aggregation and collaboration of multiple frequency bands means that devices communicate in 2.4GHz, 5.8GHz, 6GHz and other frequency bands at the same time, and for a scenario in which devices communicate in multiple frequency bands at the same time, a new medium access Control (MEDIA ACCESS Control, MAC) mechanism needs to be defined for management. In addition, aggregation and collaboration of multiple frequency bands are expected to support low latency transmission.

Currently, in the multi-band aggregation and collaboration technology, the maximum bandwidth to be supported is 320MHz (160 mhz+160 MHz), and in addition, 240MHz (160 mhz+80 MHz) and other bandwidths supported by the existing standards may be supported.

Among Wi-Fi technologies currently under study, wireless local area network (Wireless Local Area Network, WLAN) aware (Sensing) technologies may be supported. For example, application scenarios such as location discovery, proximity detection (Proximity Detection), and presence detection (Presence Detection) in dense environments (e.g., home environments and business environments).

In the WLAN awareness measurement scenario, there is a Station device (Unassociated-Station, U-STA) that does not establish an association with an Access Point device (AP), and the U-STA may participate in subsequent awareness measurement; if the U-STA participates in the subsequent sensing measurement, the AP may be required to assign a User Identifier (UID) to the U-STA; it is therefore desirable to provide a way to indicate whether an AP assigns a UID for a U-STA.

Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

The embodiment of the disclosure provides a communication method, electronic equipment and a storage medium, which are used for providing a mode for determining whether an AP needs to allocate a UID for a U-STA.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

As shown in fig. 1, the disclosed embodiments provide a communication method, optionally applicable to an access point device, which may include the steps of:

step 101, a first wireless frame is sent to a station device, and whether the first wireless frame comprises a user identifier UID distributed by the access point device AP for the station device is indicated through first indication information of the first wireless frame and/or sending time of the first wireless frame;

The UID refers to a unique identifier allocated to a site device by an AP or multi-connection access point device (AP MLD), wherein the site device is an unassociated site device (U-STA) which does not establish initial association with the AP.

As a first example, referring to fig. 2 to 4, an architecture of WLAN SENSING and a WLAN SENSING procedure to which the communication method provided by the embodiments of the present disclosure is applied are first described.

FIG. 2 shows a schematic architecture diagram of WLAN SENSING (process); where a aware Initiator Sensing Initiator (or Initiator) initiates WLAN SENSING (e.g., initiates a WLAN aware session), there may be multiple aware respondents (Sensing Responder, or aware receivers) or respondents responding thereto, as shown by respondent 1, respondent 2, and respondent 3 in fig. 2. When the awareness initiating end initiates WLAN SENSING, multiple associated or non-associated awareness responding ends WLAN SENSING may respond.

Referring to fig. 3, the sensing initiation end and the sensing response end communicate through a communication connection, as shown by a communication connection S1; the sensing response ends communicate through a communication connection S2.

Wherein each perception initiator may be a Client (Client); each of the sensing respondents (in this example, sensing respondent 1 to sensing respondent 3) may be a Station (STA) or an Access Point (AP). In addition, the STA and AP may assume multiple roles in the WLAN awareness process; for example, during WLAN awareness, the STA may also act as a awareness initiator, which may be the awareness transmitter (SENSING TRANSMITTER), the awareness receiver (SENSING RECEIVER), or both or neither. In the WLAN sensing process, the sensing response end may also be the sensing transmitting end, the sensing receiving end or both.

As another architecture, as shown in fig. 4, the sensing initiation end and the sensing response end may be both clients, and both may communicate by being connected to the same access point device (AP); in fig. 4, client1 is a sensing initiation end, and Client2 is a sensing response end.

The method comprises the steps that an AP sends a first wireless frame to a U-STA, and the U-STA is indicated by the first wireless frame to determine whether the U-STA comprises a UID distributed by the AP for the U-STA; the indication may be explicit and/or implicit. Specifically, the explicit indication manner indicates through the first indication information of the first radio frame, for example, the first indication information may occupy one bit; the bit position "0" indicates that the UID is not included in the first radio frame; the bit position "1" indicates that the UID is included in the first radio frame.

The implicit mode is determined according to the sending time of the first wireless frame; the first radio frame may be a radio frame transmitted in response to a second radio frame, and the transmission time may be a time between when the AP receives the second radio frame and when the AP transmits the first radio frame; for example, when the AP receives the second radio frame at time t1 and transmits the first radio frame at time t2, the time between time t1 and time t2 is the transmission time of the first radio frame. And if the sending time (duration) is within a preset time range, the UID is included in the first wireless frame, otherwise, the UID is not included. The U-STA may determine the transmission time according to the time when the first radio frame was received; for example, if the U-STA receives the first radio frame within a preset time range after sending the second radio frame, the first radio frame is considered to include the UID; optionally, a timer may be started when the U-STA sends the second radio frame, and if the first radio frame is received in the timing time of the timer, the UID is considered to be included in the first radio frame, otherwise, the UID is not included in the first radio frame. In addition, an explicit mode and an implicit mode can be adopted to indicate whether the first wireless frame comprises the UID distributed by the AP to the station equipment or not; for example, in the case where both explicit and implicit indications that the UID is included in the first wireless frame, determining that the UID is included in the first wireless frame; for example, the first indication information is set to "1", and the transmission time (i.e., the transmission duration) of the first radio frame is within the timer timing time, it is determined that the UID is included in the first radio frame, and otherwise, it is not included.

For example, in a Proxy By Proxy (SBP) scenario, if the U-STA does not establish any type of Sensing or ranging measurements with the AP before sending the second radio frame, the AP needs to assign a UID to the U-STA; if the U-STA has established any type of sensing or ranging measurement with the AP before transmitting the second radio frame, the AP has allocated a UID to the U-STA during the previous sensing or ranging measurement (for convenience of distinction, the UID will be referred to as a history UID later), the current time may not allocate a UID to the U-STA, but continue to establish sensing measurement using the history UID.

Alternatively, the second radio frame may be a sensing measurement setup (MeasurementSetup, MS) request frame (or a measurement setup request frame), and then the first radio frame includes an MS response frame; the second radio frame may be an MS Query frame and the first radio frame may include an MS request frame.

In a Proxy By Proxy (SBP) scenario, the second wireless frame includes a Proxy aware SBP request frame and the first wireless frame includes an SBP response frame.

In the embodiment of the disclosure, an AP sends a first radio frame to a station device, and indicates, in the first radio frame, whether the first radio frame includes a user identifier UID allocated by the access point device AP to the station device by using first indication information and/or a sending time of the first radio frame, that is, by adopting an explicit and/or implicit mode. The disclosed embodiments provide a way to determine whether an AP needs to assign a UID to a U-STA.

In the explicit indication manner, the indication is indicated by the first indication information of the first radio frame, for example, the first indication information may occupy one bit; the bit position "0" indicates that the UID is not included in the first radio frame; the bit position "1" indicates that the UID is included in the first radio frame.

Transmitting a first wireless frame to a station device, and indicating whether the first wireless frame comprises a UID distributed by the AP for the U-STA or not through the transmission time of the first wireless frame; the sending time is within a first preset time, and the UID is included in the first wireless frame; the station equipment is unassociated station equipment U-STA which does not establish initial association with the AP.

Wherein, the implicit mode is determined according to the sending time of the first wireless frame; the first radio frame may be a radio frame transmitted in response to a second radio frame, and the transmission time may be a time between when the AP receives the second radio frame and when the AP transmits the first radio frame; and if the sending time (duration) is within a preset time range, the UID is included in the first wireless frame, otherwise, the UID is not included. Alternatively, the first preset time may be 10 milliseconds (ms) or 30ms.

The U-STA can determine the sending time according to the time of receiving the first wireless frame; for example, if the U-STA receives the first radio frame within a preset time range after sending the second radio frame, the first radio frame is considered to include the UID; optionally, a timer may be started when the U-STA sends the second radio frame, and if the first radio frame is received in the timing time of the timer, the UID is considered to be included in the first radio frame, otherwise, the UID is not included in the first radio frame.

And sending a first wireless frame to site equipment, wherein the first indication information and the sending time both indicate that the UID is included in the first wireless frame, and indicate that the UID is included in the first wireless frame.

An explicit and implicit combination manner may be adopted to indicate whether the first radio frame includes a UID allocated by the AP to the station device; for example, in the case where both explicit and implicit indications that the UID is included in the first wireless frame, determining that the UID is included in the first wireless frame; for example, if the first indication information is set to "1", and the transmission time (i.e., the transmission duration) of the first wireless frame is within the timer timing time, it is determined that the UID is included in the first wireless frame; if the explicit or implicit indication mode includes a mode of indicating that the UID is not included in the first radio frame, the UID is not included.

step 501, receiving a second radio frame sent by the U-STA;

Step 502, a first radio frame is sent to a U-STA, and whether the first radio frame includes a user identifier UID allocated by the access point device AP to the U-STA is indicated by first indication information of the first radio frame and/or a sending time of the first radio frame.

Step 601, receiving an agent aware SBP request frame sent by a U-STA; the SBP request frame includes second indication information, and the first indication information indicates the U-STA to participate in wireless local area network WLAN awareness measurement.

The U-STA sends an SBP request frame to the AP, wherein the SBP request frame comprises second indication information (identification bit or information bit) for identifying the U-STA to participate in the sensing measurement, and the AP may allocate a UID to the U-STA, wherein the UID is used for identifying uplink resources or downlink resources required by the U-STA in the sensing measurement.

Step 602, an SBP response frame is sent to the U-STA, and whether the user identifier UID allocated by the AP for the U-STA is included in the SBP response frame is indicated by the first indication information of the SBP response frame and/or the sending time of the SBP response frame.

The AP transmits an SBP response frame to a station device (U-STA), and the SBP response frame indicates whether a user identifier UID allocated by the AP to the station device is included in the SBP response frame in an explicit and/or implicit mode.

The AP needs to inform the U-STA in advance that the AP supports the SBP capability information, namely the AP supports the SBP process; alternatively, the third radio frame may be a broadcast beacon (beacon) frame, or a unicast, broadcast Probe Response frame (Probe Response).

After receiving the SBP aware measurement capability information supported by the AP, the U-STA will complete Pre-association security negotiation (Pre-Associated Security Negotiation, PASN) procedure with the AP to negotiate session keys.

And establishing SBP perception measurement with the U-STA in a second preset time.

After the AP completes PASN with the U-STA, the SBP sensing measurement with the U-STA can be established in a second preset time period so as to save the electric quantity of the U-STA. Alternatively, the second preset time may be 10 milliseconds (ms).

Referring to fig. 7, an embodiment of the present disclosure provides a communication method, optionally applicable to a station apparatus, which may include the steps of:

Step 701, receiving a first wireless frame sent by an access point device AP; the station equipment is unassociated station equipment U-STA which does not establish initial association with the AP.

Specifically, the explicit indication manner indicates through the first indication information of the first radio frame, for example, the first indication information may occupy one bit; the bit position "0" indicates that the UID is not included in the first radio frame; the bit position "1" indicates that the UID is included in the first radio frame.

The implicit mode is determined according to the sending time of the first wireless frame; the first radio frame may be a radio frame transmitted in response to a second radio frame, and the transmission time may be a time between when the AP receives the second radio frame and when the AP transmits the first radio frame; for example, the U-STA transmits the second radio frame at time t1 and receives the first radio frame at time t2, and the time between time t1 and time t2 is the transmission time of the first radio frame. And if the sending time (duration) is within a preset time range, the UID is included in the first wireless frame, otherwise, the UID is not included.

In addition, an explicit mode and an implicit mode can be adopted to indicate whether the first wireless frame comprises the UID distributed by the AP to the station equipment or not; for example, in the case where both explicit and implicit indications that the UID is included in the first wireless frame, determining that the UID is included in the first wireless frame; for example, the first indication information is set to "1", and the transmission time (i.e., the transmission duration) of the first radio frame is within the timer timing time, it is determined that the UID is included in the first radio frame, and otherwise, it is not included.

To further identify whether a UID is carried, a bit may be used to identify whether a UID is contained in the SBP response frame, e.g., the U-STA and the AP have previously established any form of sensing or ranging measurements, then this bit is set to "0" to identify that no UID is contained, beyond the time of timing that the previously assigned UID cannot be reused by the U-STA, and if not, to "1" to identify that a UID is contained in the frame.

Alternatively, the second radio frame may be a perceptual measurement setup (MeasurementSetup, MS) request frame, and the first radio frame includes an MS response frame; the second radio frame may be an MS Query frame and the first radio frame may include an MS request frame.

In the embodiment of the disclosure, a U-STA receives a first radio frame sent by an AP, and determines, according to first indication information of the first radio frame and/or a sending time of the first radio frame, whether the first radio frame includes a user identifier UID allocated by the AP to the U-STA, that is, whether the first radio frame includes the user identifier UID allocated by the AP to the station device in an explicit and/or implicit manner.
