Description

Channel occupying method, frame period indicating method, frame period determining method and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a channel occupying method, a frame period indicating method, a frame period determining method, and a device.

Background

In future communication systems, an Unlicensed Band (Unlicensed Band) may be used as a supplement to a licensed Band (licensed Band) to help an operator to expand the capacity of services. Since the unlicensed frequency band is shared by multiple Radio Access Technologies (RATs), for example, wireless fidelity (Wi-Fi), radar, Long Term Evolution (LTE-LAA) based Licensed Assisted Access frame for Long Term Evolution (LTE-LAA), and the like. Therefore, the unlicensed band must meet regulatory regulations when used to ensure that all devices can fairly share the resource, such as Listen Before Talk (LBT), Maximum Channel Occupancy Time (MCOT), and so on. When a transmission node needs to send information, the transmission node requires to execute LBT on a specified wireless channel first, and performs Energy Detection (ED) on the surrounding wireless transmission environment, and when the Energy is lower than a certain threshold, the channel is judged to be idle, and then transmission can be started; otherwise, the channel is judged to be busy, and the transmission node can not transmit. The transmission node may be a base station, a terminal device, a Wi-Fi wireless Access Point (AP), or the like. After the transmission node starts transmission, the occupied channel time cannot exceed the MCOT.

Frame Based Equipment (FBE) means that the transmission or reception timing of the Equipment adopts a periodic structure, and the Period is a Fixed Frame Period (Fixed Frame Period).

The FBE node occupies a channel by using a LBT-based channel access mechanism, wherein a node Initiating a transmission sequence including one or more continuous transmissions is called an Initiating node (Initiating Device), and other nodes are called Responding nodes (Responding devices). The FBE node may be an initiating node, a responding node or both.

The operational requirements of the originating node include:

a Fixed Frame Period value set supported by the nodes is declared by a device manufacturer, and each value requirement is within the range of 1-10 ms. The transmission can be started only at the starting time of a certain Fixed Frame Period, and the node can change the currently applied Fixed Frame Period, but the frequency of the Fixed Frame Period cannot be higher than 200ms once.

Before starting transmission at the starting time of a Fixed Frame Period, the initiating node will perform Clear Channel Assessment (CCA), and if it is determined to be idle, it may immediately transmit the Frame, otherwise, it is not allowed to transmit within the duration of the next Fixed Frame Period (except for short control signaling Transmissions specified by regulatory requirements).

In a Fixed Frame Period that has started to be sent, the corresponding initiating node can determine the total duration of transmission without re-estimating the availability of the Channel, and the total duration is defined as the Channel Occupancy Time (COT). The initiating node may transmit multiple times on the designated channel within the COT without performing an additional CCA, as long as the time interval between adjacent ones of these transmissions does not exceed 16 μ s. If the time interval between adjacent transmissions within the COT exceeds 16 mus, the initiating node needs to perform an additional CCA before continuing the transmission, and the transmission continues only if the CCA determines that the channel is clear. The time interval between all adjacent transmissions takes into account the COT duration.

The initiating node may grant usage rights for a specified channel for certain time periods within the COT to one or more associated responding nodes for transmission.

The COT cannot be longer than 95% of the Fixed Frame Period, and an Idle Period (Idle Period) follows the COT and continues until the start time of the next Fixed Frame Period ends, so that the length of the Idle Period is at least 5% of the Fixed Frame Period, and the minimum value is 100 μ s.

A node may transmit management and control frames (e.g., Acknowledgement (ACK) frames) corresponding to a data packet on a designated channel immediately after receiving the data packet for it correctly without CCA. The node needs to ensure that these consecutively transmitted frames cannot exceed the above-mentioned maximum COT duration.

After receiving the authorization of the initiating node to use the designated channel for a certain period of time, the responding node performs the following operations:

the responding node does not need to perform CCA prior to transmission if it initiates a transmission at most 16 mus after the initiating node indicates the end of the last transmission of the grant; otherwise, executing CCA before the authorized transmission time interval begins, if the channel is busy, giving up the authorization, otherwise, starting transmission on the appointed channel, occupying the rest part of COT in the current Fixed frame period at most, starting multiple transmissions in the time range of the rest part, as long as the time interval of adjacent transmissions does not exceed 16 mus, and giving up the authorization after the transmission is finished.

For a network operating based on FBE, if the Frame timing of each node cannot guarantee full synchronization (it is considered to be full synchronization only when the Fixed Frame Period adopted by each node has equal value and the start time of each Frame Period is completely aligned), the node occupying the favorable time position will continuously occupy the channel (the actual channel occupies a higher priority level) when there is a large amount of data to be continuously transmitted, and some example cases of the favorable time position include:

when the Fixed Frame Period configurations of the nodes are the same, the node closer to the start of the Frame Period monitors and preempts the channel in advance, for example, node two in fig. 1.

When the Fixed Frame Period configurations of the nodes are different, the Frame timing of some nodes can enable the nodes to monitor and preempt the channel in advance with a high probability, such as the second node in fig. 2 and 3.

When a large amount of data needs to be continuously transmitted, the nodes occupying the favorable time positions continuously occupy the channel, so that other adjacent nodes are difficult to successfully occupy the channel, unfair channel occupation is caused, the priority of the partial nodes actually occupying the channel is reduced, the probability of successfully acquiring channel resources is reduced, and lower data transmission capacity and larger transmission delay are caused.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 4, an embodiment of the present invention provides a channel occupying method, applied to a first device based on a frame, including:

step 401, performing cumulative counting on the continuous number of the frame periods of the target channel occupied by the first device to obtain a count value.

In this step, the accumulated count specifically includes: when the first device occupies the target channel for a first frame period, the count value is set to 1, and every additional frame period which is consecutive in time to the previous occupied frame period is occupied, the count value is increased by 1.

Step 402, when the count value is greater than or equal to N, starting from the next frame period, the first device stops listening and occupying the target channel within M consecutive frame periods;

In this step, when the count value is greater than or equal to N, starting from the next frame period, the first device stops listening and occupying the target channel in M consecutive frame periods, and then the first device continues listening and occupying the target channel as needed, and re-executes the operation of accumulating the count when the target channel is occupied, and executes the mute operation when the accumulated count reaches N (the mute operation specifically is to stop listening and occupying the target channel in M consecutive frame periods).

Wherein, the next frame period specifically is: when the count value is greater than or equal to N, in a next frame period adjacent to the current frame period, for example, N is equal to 4, and M is equal to 2, the count value of the first frame period occupying the target channel is 1, the count value of the second frame period occupying the target channel is 2, the count value of the third frame period occupying the target channel is 3, and the count value of the fourth frame period occupying the target channel is 4 (where the first frame period, the second frame period, the third frame period, and the fourth frame period are consecutive frame periods), and at this time, the count value is equal to 4, the monitoring and occupation of the target channel are stopped in 2 consecutive frame periods from the fifth frame period, that is, the first device stops monitoring and occupies the target channel in the fifth frame period and the sixth frame period.

It should be noted that, in M frame periods when the first device stops listening and occupying the target channel, the neighboring devices around may listen and occupy the target channel as needed, so as to avoid the single device from occupying the channel for a long time to block or postpone data transmission of the neighboring devices around.

The first device is a frame-based device, i.e., FBE, and may also be referred to as a first FBE, and similarly, the second device may also be a frame-based device, i.e., a second FBE. Preferably, the first device is a device that can serve as an initiator node, and may also be referred to as an initiator node.

Optionally, if the count value of the first device does not satisfy the condition that is greater than or equal to N, the silence of M frame periods does not need to be considered, and the first device listens and occupies the channel according to the data transmission requirement of the first device.

As an alternative embodiment, the values of the two parameters N and M may be determined based on at least one of the following manners:

the value of N and/or the value of M are configured by the network, or the value interval of N and/or the value interval of M are configured by the network.

The value of N and/or the value of M are agreed by the protocol, or the value interval of N and/or the value interval of M are agreed by the protocol.

When the first device determines that the value interval of N and/or the value interval of M is/are, the method further includes:

uniformly and randomly selecting an integer from the value interval of N as the value of N; for example, if the value interval of N is [1,8], the value of N may be any one of 1,2,3,4,5,6,7, and 8.

And/or the presence of a gas in the gas,

uniformly and randomly selecting an integer from the value interval of M as the value of M; for example, if M has a value interval of [1,5], M may have a value of any one of 1,2,3,4, and 5.

As another embodiment, the method provided in the embodiment of the present invention further includes:

adjusting the value of a parameter according to the occupation information of the target channel; wherein, the value of the parameter comprises at least one of the following: the value of N, the value of M, the upper limit value of the value interval of N and the upper limit value of the value interval of M.

In short, at least one of the value of N, the value of M, the upper limit value of the value interval of N, and the upper limit value of the value interval of M may be adaptively adjusted according to the occupation information of the target channel, so as to dynamically match the occupation condition of the target channel.

It should be noted that, if the upper limit value of the value interval of N and/or the upper limit value of the value interval of M is adjusted, the first device determines the value of N and/or M according to the adjusted value interval. The method specifically comprises the following steps:

uniformly and randomly selecting an integer from the value range of the N obtained after adjustment as the value of the N; and/or uniformly and randomly selecting an integer from the value range of the M obtained after adjustment as the value of the M.

Preferably, in the above embodiment of the present invention, the adjusting the value of the parameter according to the occupation information of the target channel includes:

the first equipment monitors a target channel in continuous M frame periods of stopping monitoring and occupying the target channel, acquires an idle ratio of the target channel, and adjusts the value of the parameter according to the idle ratio; the idle ratio of the target channel is as follows: and monitoring the target channel and judging the proportion of idle monitoring times to the total monitoring times.

When the first device needs to silence for M frame periods, periodically or regularly sampling and monitoring the target channel in M frame periods in which the target channel is not monitored and occupied, and counting the idle ratio of the target channel based on the blind idle condition of the target channel (the idle ratio is the ratio of the monitoring times of the channel judged to be idle to the total monitoring times in the M frame periods).

The first device adjusts the value of the parameter based on the idle ratio of the target channel, and if the value of N or the upper limit value of the value interval of N is adjusted, the first frame period after the current M frame periods comes into effect; if the value of M or the upper limit value of the value interval of M is adjusted, the M value is effective when the M value needs to be used for the first time after the current M frame periods.

Or, the adjusting the value of the parameter according to the occupation information of the target channel includes:

the first equipment monitors a target channel in a frame period without data transmission, acquires an idle ratio of the target channel, and adjusts the value of the parameter according to the idle ratio; the idle ratio of the target channel is as follows: monitoring the target channel and determining the proportion of idle monitoring times to total monitoring times

The first device monitors the target channel periodically or by other rules in the frame period without data transmission, and periodically counts the idle ratio of the target channel in a certain number of frame periods without data transmission recently (the idle ratio is the ratio of the monitoring times that the channel judges to be idle in the frame periods without data transmission to the total monitoring times), or counts the idle ratio of the channel in each frame period without data transmission, or counts the idle ratio of the target channel at intervals in other feasible modes.

At the time point of counting the idle ratio of the channel, the first device adjusts the value of the parameter based on the idle ratio of the channel, and if at least one of the value of N, the value of M, the upper limit value of the value interval of N, and the upper limit value of the value interval of M is adjusted, the adjusted value starts to take effect when the value of N or the value of M needs to be used for the first time after the time point (i.e., the time point of counting the idle ratio of the channel).

As an embodiment, the adjusting the value of the parameter according to the idle ratio includes:

subtracting a single step length from the value of M or the upper limit value of the value interval of M under the condition that the idle ratio is greater than or equal to a first threshold value; and if the value of M or the upper limit value of the value interval of M is less than or equal to the first minimum value, taking the first minimum value as the value of M or the upper limit value of the value interval of M. The first minimum value may be set to 1, either based on network configuration or specified by a protocol.

And/or the presence of a gas in the gas,

under the condition that the idle ratio is larger than or equal to a first threshold value, increasing the value of N or the upper limit value of the value interval of N by a single step length; and if the value of N or the upper limit value of the value interval of N is greater than or equal to the second maximum value, taking the second maximum value as the value of N or the upper limit value of the value interval of N. The second maximum value may be based on a network configuration or specified by a protocol.

The upper limit value of the value of N or the value interval of N is greater than or equal to the second minimum value and less than or equal to the second maximum value; the upper limit value of the value of M or the value interval of M is greater than or equal to the first minimum value and less than or equal to the first maximum value.

It should be noted that the step size may be set to 1 or other values, and is not limited in this respect.

As another embodiment, the adjusting the value of the parameter according to the idle ratio includes:

when the idle ratio is larger than or equal to a first threshold value, subtracting a single step length from the upper limit value of the value of M or the value interval of M, and if the upper limit value of the value of M or the value interval of M is equal to a first minimum value, increasing the upper limit value of the value of N or the value interval of N by the single step length; and if the value of N or the upper limit value of the value interval of N is greater than or equal to the second maximum value, taking the second maximum value as the value of N or the upper limit value of the value interval of N.

under the condition that the idle ratio is smaller than or equal to a second threshold value, increasing the value of M or the upper limit value of the value interval of M by a single step length; and if the value of M or the upper limit value of the value interval of M is greater than or equal to the first maximum value, taking the first maximum value as the value of M or the upper limit value of the value interval of M. The first maximum value may be based on a network configuration or specified by a protocol.

And/or the presence of a gas in the gas,

reducing the value of N or the upper limit value of the value interval of N by a single step length under the condition that the idle ratio is less than or equal to a second threshold value; and if the value of N or the upper limit value of the value interval of N is less than or equal to the second minimum value, taking the second minimum value as the value of N or the upper limit value of the value interval of N. The second minimum value may be set to 1, or may be based on network configuration or specified by a protocol.

under the condition that the idle ratio is smaller than or equal to a second threshold value, firstly reducing the upper limit value of the value of N or the value interval of N by a single step length, and if the upper limit value of the value of N or the value interval of N is equal to a second minimum value, increasing the upper limit value of the value of M or the value interval of M by a single step length; and if the value of M or the upper limit value of the value interval of M is greater than or equal to the first maximum value, taking the first maximum value as the value of M or the upper limit value of the value interval of M.

Optionally, the first threshold and the second threshold may be equal, or the first threshold is greater than the second threshold.

The second minimum value corresponding to the value of N and the second minimum value corresponding to the value interval of N may be the same value or different values; the second maximum value corresponding to the value of N and the second maximum value corresponding to the value interval of N may be the same value or different values; similarly, the first minimum value corresponding to the value of M and the first minimum value corresponding to the value interval of M may be the same value or different values; the first maximum value corresponding to the value of M and the first maximum value corresponding to the value interval of M may be the same value or different values.

Further, in the foregoing embodiment of the present invention, in a case that the frame-based first device is a network-side device, for an unauthorized communication system, the method further includes:

when the first device is started and is in an open state, the first device detects the surrounding environment, or detects the surrounding environment according to auxiliary information reported by the terminal device, so as to obtain a detection result; the detection result is used for indicating whether the first equipment detects equipment which uses a target channel and has preset characteristics;

if the equipment which uses the target channel and has the preset characteristics is detected for a single time or continuously for multiple times, accumulating and counting the continuous number of the frame periods of the target channel occupied by the first equipment; that is, if a device using the target channel and having the predetermined characteristic is detected for a single time or multiple consecutive times, the first device executes the loop of step 401 and step 402.

When the device using the target channel and having the preset feature is not detected for a single time or multiple times, the number of consecutive frame periods in which the first device occupies the target channel is not counted by accumulating, that is, step 401 is not executed (step 402 cannot be executed because step 401 is not executed), which may also be called setting N to infinity and setting M to 0, that is, the first device does not need to consider the accumulated count and silence of M frame periods, and the first device listens to and occupies the channel according to its own data transmission requirement.

Preferably, the preset features include at least one of:

the network behavior of the device complies with a preset version of the Wi-Fi specification;

the device is a network side device of an unauthorized communication system of an operator different from the first device;

the deviation between the position of the frame period of the device (which may be the start position or the end position of the frame period) and the position of the frame period of the first device (which corresponds to the position of the frame period of the device, for example, if the position of the frame period of the device is the start position of the frame period, the position of the frame period of the first device is also the start position) is greater than a preset threshold, and the device is a network-side device of an unlicensed communication system belonging to the same operator.

In short, the first device starts and terminates the aforementioned consecutive frame period accumulation count and muting operations based on the detection condition of the neighboring device of the preset feature; for example, when the network-side device (i.e., the first device) does not detect the neighboring device with the preset feature, the first device may not start the consecutive frame period counting and muting operation, and start the consecutive frame period counting and muting operation after detecting or detecting the neighboring device with the preset feature for multiple times; further, if the adjacent device with the preset characteristic is not detected for a single time or a plurality of times after the starting, the accumulation counting and the silencing operation of the continuous frame periods are stopped, and the steps are repeated.

In summary, in the above embodiments of the present invention, the frame-based device serving as the initiating node performs accumulated counting on frame periods that the initiating node continuously occupies on the target channel, and stops monitoring and occupying the target channel within M frame periods from the next frame period when the count value is greater than or equal to N, so as to avoid that a single device occupies the target channel for a long time, and improve fairness of channel occupation among devices.

It should be noted that, the manner of accumulating count and muting operation in consecutive frame periods provided by the embodiment of the present invention can avoid that a single device occupies a channel for a long time, but for the case that the maximum value of the count value is smaller than N, the following problems still exist:

for the above coordination/restriction mechanism based on continuous occupied frame Period accumulated count and silent operation, if a device occupying an advantageous time position always continuously transmits only N-1 frame periods on a target Channel when a large amount of data needs to be continuously transmitted, then leaves 1 frame Period without transmission, and continues to monitor and occupy the Channel in the next frame Period, and if the time of its Channel Clear Channel Assessment (CCA) is always within the Idle Period (Idle Period) of other adjacent node frame periods, it can successfully occupy the Channel again and continuously transmit N-1 frame periods, so that the limit of M can be ignored, resulting in unfair preferential Channel occupation.

As shown in fig. 5, assume that the parameters of the network at this time are set to: the maximum number N of the continuously occupied frame periods is 3; the number of silence frame periods M is 2. The frame timing of the node two occupies an advantageous time position, and the CCA position of the node two is located in the idle period of the frame period of the node one, and the node two can always CCA successfully when needed no matter whether the node one occupies the channel or not, namely, the channel is detected to be idle, so that the channel can be occupied and data transmission can be carried out in the next frame period. When a second node has a large amount of data to be transmitted, after continuously transmitting for 2 frame periods, in order to avoid continuously occupying additional frame periods and satisfy the condition that the continuously transmitted frame period is N, one frame period is vacated without performing channel monitoring and data transmission, then the channel is continuously monitored for CCA in the next frame period (the CCA is always successful because the CCA occupies a favorable time position), and continuously transmitting for 2 frame periods again, and repeating the steps, thereby avoiding the operation of requiring silence for continuous M frame periods.

In order to further avoid the above problem, the method provided by the embodiment of the present invention further includes:

the first device sends configuration indication information to a peripheral network, wherein the configuration indication information is used for indicating a frame period adopted by the first device and the position of the frame period.

In this case, the first device is an initiating node that has already been started to operate, and the first device sends the configuration indication information in any one of the following manners:

periodically broadcasting the configuration indication information on a target channel; for example, short control signaling transport mechanisms allowed by regulatory requirements may be employed.

And sending the configuration indication information to the second equipment when a wired network interface is established with the newly deployed second equipment.

Further, in a case that a frame period and/or a position of the frame period indicated by the configuration indication information changes, the method further includes:

and sending the changed configuration indication information to the second equipment through the established wired network interface.

When the newly deployed second device is started, the newly deployed second device firstly monitors and detects the surrounding environment on the target channel, or receives corresponding information when a wired network interface is established with a peripheral node, so that the frame period and the position of the frame period adopted by the adjacent device (namely, the first device) are obtained, a proper frame period and a proper position of the frame period are selected for the second device, and the corresponding CCA position is ensured not to always fall within the idle time period of the frame period of the first device. And then the second equipment is used as a started and operated node to inform the peripheral network of the frame period and the frame period position adopted by the second equipment.

The scheme can realize the random occupation of the channel among the nodes through the exclusive blocking effect when occupying the target channel. The scheme can be used as the operation of selecting a frame timing phase when the nodes are deployed and started, and is jointly deployed by combining the scheme based on continuous occupation frame period accumulation counting and silence.

As shown in fig. 6, an embodiment of the present invention further provides a frame period indication method, applied to a first device based on a frame, including:

step 601, sending configuration indication information to a peripheral network, where the configuration indication information is used to indicate a frame period adopted by the first device and a position of the frame period.
