Embodiments of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

1 is a flowchart of a spectrum sharing method according to an embodiment of the present invention. As shown in FIG. 1, the method includes:

Step 100: The transmitting node determines an initial data transmission time and a silent time in a preset time.

In this step, the transmission node is a transmission node in one of the transmission systems using the shared spectrum, and the transmission system may be an LTE system.

In this step, it is assumed that the preset time is T1, the data transmission time is T2, the silence time is T3, and T1=T2+T3. It is determined that the initial data transmission time T2 and the silence time T3 within the preset time T1 may adopt one of the following methods:

The first way:

Detecting the number of transmission nodes of the first system, and the number of transmission nodes of other systems and/or the resource idle condition of the shared spectrum within the detection time window W in the detection time window W;

Determining an initial data transmission time T2 and silence time T3, the initial data transmission time and the minimum value _min T2 T2 based on the detected information.

Or,

Detecting activity of transmission nodes of other systems in the detection time window W, and service requirements of the transmission nodes of the first system and/or resource idle conditions of the shared spectrum within the detection time window W;

Determining an initial data transmission time T2 and silence time T3, the initial data transmission time and the minimum value _min T2 T2 based on the detected information.

The detection time window W includes a silent time, or the detection time window W is a preset time window.

The specific implementation of determining the data transmission time T2 and the silence time T3, and the minimum value T2 _min of the initial data transmission time T2 is easily implemented by a person skilled in the art, and the implementation manner is also many, and is not limited to one type. . Here is an example, for example, according to the number of transmission nodes, assuming that the number of transmission nodes of the first system and other systems are X and Y, respectively, the transmission time T2 can be determined as X/(X+Y)*T1, silent time T3 can be determined as Y/(X+Y)*T1. The preset time T1 may be determined based on the detection time window W, or may be notified to the transmission node of the first system by a carrier (also referred to as an authorized carrier) on the licensed spectrum, where T1=T2+T3.

Wherein, how to detect a well-known technology belonging to those skilled in the art, the specific implementation is not intended to limit the scope of protection of the present invention, and generally includes: by detecting some unique signals (such as synchronization signals) of the first system and/or other systems. Detecting the number of transmission nodes of the first system and/or other systems; detecting the resource idleness of the shared spectrum in the time window by detecting the signal energy in the detection window, when the unit time (or the preset time length) is detected When the signal energy is lower than the preset threshold, the channel resource is considered to be idle.

The second way:

The carrier on the licensed spectrum notifies the transmission node of the first system by signaling, the initial data transmission time T2 and the silence time T3, and the minimum value T2 _{min of the} initial data transmission time T2. It is emphasized here that by signaling the carrier on the licensed spectrum, the existing signaling or the newly defined signaling may be utilized, which is not intended to limit the scope of protection of the present invention.

The third way:

The initial data transmission time T2 and silence time T3, and the default value of the initial data transmission time T2 T2 _min is the minimum value set in advance, such as T2: T3 = 1: 1, the initial data transmission time T2 is the minimum value T2 _min Equal to the initial data transmission time T2.

In this step, the detection time window W may be periodic, and the period size is configured by signaling on the carrier on the licensed spectrum, or may be preset;

Alternatively, the detection time window W is triggered, and the transmission node of the first system is triggered by the carrier on the licensed spectrum to perform re-detection; further, the condition that the carrier on the licensed spectrum triggers the retransmission of the transmission node of the first system may include: It is not limited to the following: the number of transmission nodes of the first system and other systems varies greatly; or the service of the first system or other systems undergoes a large change.

Step 101: The transmitting node performs data transmission on the shared spectrum during the data transmission time, and detects resource utilization on the shared spectrum in a silent time.

In this step, during the data transmission time T2, the transmission node of the first system uses the mechanism of the existing first system for data transmission. During the data transmission time T2, the transmission nodes of other systems cannot be occupied.

Further, the starting point of the data transmission time T2 of all the transmission nodes of the first system within the network coverage is aligned.

The detection of resource utilization on the shared spectrum in the silent time in this step specifically includes:

According to the preset time granularity T _step , the silent time T3 is divided into a plurality of equal parts, assuming N equal parts, each aliquot is called a time granularity T _step aliquot, and the length of time is equal to the time granularity T _step ;

Detecting resource utilization on the shared spectrum within each time granularity T _step ;

When it is detected that the signal energy in the time granularity T _step is lower than the preset threshold, the resource in the time granularity T _step is marked as idle, and the idle resource counter K may be added to the processing.

The time granularity T _step may be determined by a transmission unit of a certain system, such as a subframe of the LTE system, etc., it should be noted that how to determine the temporal granularity T _step is merely a simple example, and is not used. The scope of protection of the present invention is not limited thereto.

Step 102: Adjust the data transmission time and the silence time in the next preset time according to the detected resource utilization on the shared spectrum.

The data transmission time and the silence time in the next preset time in this step include: when the resource is idle during the silence time T3, the data transmission time in the next preset time T1 is adjusted in one of the following manners. T2' and silence time T3':

The first adjustment method:

If the idle resource has k equal parts and k<N, the k idle time granularity T _{step is} adjusted to the data transmission time T2′ of the next preset time T1: the data transmission time T2′ of the next preset time T1 The sum of the product of the data transmission time T2 of the current preset time T1 and the product of the number of idle resources k and the time granularity T _step , that is, T2′=T2+kT _step ; the silent time T3′ of the next preset time T1 The difference between the silent time T3 of the current preset time T1 and the product of the product of the idle resource number k and the time granularity _Tstep , that is, T3'=T3-kT _step ;

If the idle resource has k equal parts and k=N, the (k-1) idle time granularity _{Tstep is} adjusted to the data transmission time T2' of the next preset time T1: data of the next preset time T1 the transmission time T2 of the current preset time T1 data transmission time T2 and (the number of idle resource k-1) product value of the product of the time granularity T _step of and, i.e. T2 '= T2 + (k- 1) T step; The quiet time of the next preset time T1 is the time granularity T _step , that is, T3=T _step ;

If there are no free resources, no adjustment; or a preset time T1 the next data transmission time T2 'is adjusted to the minimum value of the data transmission time T2 _min T2, i.e. T2 = T2 _min, at a preset time T1 silence period T3 'time T1 is preset to a preset value difference of the data transmission time of the time T1 T2 T2 is the minimum value _min of the current, i.e., T3' = T1-T2 _min;

Specifically, if p idle aliquots are continuously detected, the silent period is terminated, and the data transmission time T2' of the next preset time T1 is immediately immediately advanced. Here, it is assumed that the resources after the consecutive p idle equal resources in the original silent period are also idle. Therefore, the data transmission time T2' of the next preset time T1 is the data transmission time T2 of the current preset time T1 and The sum of the product values of the product of the equal number Nm and the time granularity _Tstep , that is, T2'=T2+(Nm) _Tstep ; the silent time T3' of the next preset time T1 is m and the silent time time The product of the product of the granularity T _step , that is, T3' = mT _step . Where m is the number of aliquots of resources that are detected before the p consecutive aliquots are detected, and m+p<=N is assumed here.

The second adjustment method:

If the idle resource has k equal parts and k>1, the (k-1) idle time granularity T _{step is} adjusted to the time T2 ′ of the data transmission of the next preset time T1, and the next preset time T1 The data transmission time T2' is the sum of the product of the data transmission time T2 and the (free resource number k-1) and the time granularity _Tstep of the current preset time T1, that is, T2'=T2+(k-1)T _Step ; the silent time T3' of the next preset time T1 is the product of the difference between the difference between the equal score N and the (free resource number k-1) and the time granularity _Tstep , that is, T3'=(N -k+1)T _step ;

If only one aliquot of resources is available, no adjustments are made;

If there is no idle resource, the time T2′ and the silent time T3′ of the data transmission of the next preset time T1 are adjusted according to the step size of the time granularity T _step , which specifically includes: the data transmission time T2′ of the next preset time T1. The difference between the current data transmission time and the time granularity T _step , that is, T2′=T2-T _step ; the silent time T3′ of the next preset time T1 is the current silent time and time granularity T _step and the sum, i.e., T3 '= T3 + T _step; wherein the next predetermined time period after the adjustment of the data transfer time T1 T2' that is not less than or equal to the initial data is greater than the transmission time of the minimum value T2 _min T2, if The data transmission time T2 of the current preset time T1 is equal to the minimum value T2 _{min of the} data transmission time T2, and no adjustment is performed;

Specifically, if p idle aliquots are continuously detected, the silent period is terminated, and the data transmission time of the next preset time T1 is directly advanced in advance. Here, it is assumed that the resources after the consecutive p idle equal resources in the original silent period are also idle. Therefore, the data transmission time T2' of the next preset time T1 is the data transmission time T2 of the current preset time T1 and The sum of the product values of the product of the equal-quantity Nm-1 and the time granularity _Tstep , that is, T2'=T2+(Nm-1) _Tstep ; the silent time T3' of the next preset time T1 is (m) +1) a product value of the product of the quiet time time granularity _Tstep ; wherein m is a number of resource aliquots detected before the p idle aliquots are continuously detected, and m+ is assumed here. p<=N.

In the data transmission time and the silent time mode of the next preset time in the adjustment of this step, p is a preset value.

If the detection time window W is periodic, then continue to adjust until the end of the period of the detection time window W, and wait for the detection time window of the next week to arrive; if the detection time window W is triggered, then continue to adjust until the reception is received again. Trigger the detection time window.

Through the method of the invention, the coexistence problem between the LTE system and other systems on the shared spectrum is solved, and the normal operation of the LTE on the shared spectrum is realized.

    The data transmission time of the next preset time T1 T2 'current is adjusted to the data transmission time T2 of the preset time T1 T2 minimum value _min; i.e., T2' = T2 _min; the next preset time T1 of the silent The time T3′ is the difference between the preset time T1 and the minimum value T2 _min of the data transmission time T2 of the current preset time T1; that is, T3′=T1-T2 _min ;

    Wherein, the plurality of aliquots are N equal parts, and N is T3/T _step ;

    Alternatively, the adjustment module is set to:

    When p idle aliquots are continuously detected, the data transmission time T2' of the next preset time T1 is entered;

    The data transmission time T2' of the next preset time T1 is the sum of the product of the data transmission time T2 of the current preset time T1 and the product of the (equal fraction Nm) and the temporal granularity _Tstep , that is, T2' =T2+(Nm)T _step ;

    The silent time T3' of the next preset time T1 is a product of the product of m and the silent time time granularity _Tstep , that is, T3'=mT _step ;

    Where m is a number of aliquots of resources that are detected before being continuously detected for p idle aliquots; and m+p<=N;

    Alternatively, the adjustment module is set to:

    When the idle resource has k equal parts and k>1, the (k-1) idle time granularity _{Tstep is} adjusted to the time T2' of the data transmission of the next preset time T1:

    The data transmission time T2' of the next preset time T1 is the sum of the product value of the product of the data transmission time T2 and the (free resource number k-1) of the current preset time T1 and the time granularity _Tstep , That is, T2'=T2+(k-1)T _step ;

    And, the silent time T3′ of the next preset time T1 is a product of the difference between the difference between the equal score N and the (free resource number k-1) and the time granularity T _step , that is, T3 '=(N-k+1)T _step ;

    Or, when only one aliquot of resources is idle, no adjustment is made;

    Alternatively, when there is no idle resource, the time T2′ and the silence time T3′ of the data transmission of the next preset time T1 are adjusted according to the step size for the time granularity T _step :

    The next time a predetermined data transfer time T1 T2 'is the time difference between the current data and the difference between the transmission time T _step of particle size, i.e. T2' = T2-T _step; the next preset time The silent time T3' of T1 is the sum of the sum of the current silent time T3 and the temporal granularity _Tstep , that is, T3'=T3+ _Tstep ; wherein, the data transmission time T2 of the next preset time T1 Is greater than or equal to the minimum value T2 _min of the initial data transmission time T2; if the data transmission time T2 of the current preset time T1 is equal to the minimum value T2 _{min of the} data transmission time T2, no adjustment is performed;

    Alternatively, the adjustment module is set to:

    When continuously detecting p idle aliquot resources, the data transmission time T2' of the next preset time T1 is entered;

    The data transmission time T2' of the next preset time T1 is the sum of the product of the data transmission time T2 of the current preset time T1 and the product of the (equal fraction Nm-1) and the time granularity _Tstep , that is, T2'=T2+(Nm-1)T _step ;

    The silent time T3 ′ of the next preset time T1 is a product of the product of (m+1) and the silent time time granularity T _step ;

    Where m is the number of aliquots of resources that are detected before the p consecutive aliquot resources are continuously detected; and m+p<=N.
