As shown in fig. 2, the present embodiment provides a method for processing resource allocation, which is applied to a first device, and the method includes the following steps:

step S21: receiving a reference signal sent by second equipment;

step S22: determining the channel quality transmitted by the second equipment on idle Resource Blocks (RBs) and allocating the weight coefficient of each idle RB to the second equipment according to the receiving quality of the reference signal;

step S23: and sending the resource scheduling information of the allocated idle RB to the second equipment according to the channel quality and the weight coefficient.

In this disclosure, the first device may be a base station or a user equipment. The second device is a user device.

Here, the base station may be an access device for accessing the user equipment to the mobile network. The base station may be various types of base stations, for example, the base station may be a 3G base station, a 4G base station, a 5G base station, or the like.

Here, the user device may be a mobile phone, a computer, a server, a transceiver device, a tablet device, a medical device, or a wearable device, and so on.

For example, in some cellular network application scenarios, the first device is a base station. As another example, in some application scenarios of Device to Device (D2D) or vehicle to wireless communication technology (V2X), the first Device is a user equipment if there is no need for a base station to allocate resources. For another example, in some application scenarios of D2D or V2X, if the base station needs to allocate resources, the first device is the base station.

Here, the reference signal is a signal for channel measurement. For example, the Reference signals are Demodulation Reference Signal (DMRS) and uplink Sounding Reference Signal (SRS).

In some embodiments, the step S22 includes:

determining the channel quality transmitted by the second equipment on an idle Resource Block (RB) according to the receiving quality of the reference signal;

and distributing the weight coefficient of each idle RB for the second equipment according to the receiving quality of the reference signal.

The reception quality includes at least one of:

signal to noise ratio;

a signal-to-interference ratio;

a transmission power;

the power is received.

Here, the signal-to-noise ratio is a ratio of a useful signal to a noise signal.

Here, the signal-to-interference ratio is a ratio of a desired signal to a sum of an interference signal and a noise signal.

In an embodiment, the determining, according to the reception quality of the reference signal, the channel quality of transmission on idle resource blocks RB by the second device includes:

and determining the channel quality transmitted by the second equipment on the idle Resource Block (RB) according to the signal-to-noise ratio in the receiving quality.

Of course, in other embodiments, the channel quality of the second device uploading on the RB may also be determined according to the signal-to-interference ratio in the reception quality.

In some embodiments, the determining, according to the reception quality of the reference signal, a weight coefficient for allocating each idle RB to the second device includes:

Here, the idle RB is an RB that has not been allocated or an RB to be allocated.

In an embodiment, the determining a path loss of the second device according to the reception quality of the reference signal comprises:

determining the path loss of the second device based on a difference between a transmit power and a receive power in the reception quality.

Here, the weight coefficient is determined according to a path loss and/or a position of the free RB in a channel bandwidth.

In the disclosed embodiments, the weight coefficient is positively correlated with the probability of being allocated to an idle RB. That is, in response to the weight coefficient being larger, it means that the second device is more easily allocated to the idle RB; indicating that the second device is harder to allocate to the free RB in response to the smaller weight coefficient.

For example, in response to the weight factor being a first value, the probability that the second device is assigned to the free RB is a first probability; in response to the weight coefficient being a second value, the probability that the second device is assigned to the idle RB is a second probability; wherein the first numerical value is greater than the second numerical value, and the first probability is greater than the second probability.

Thus, in the embodiment of the present disclosure, when allocating an idle RB to the second device, not only the channel quality of the second device in the idle RB is considered, but also a weight coefficient allocated to the idle RB to the second device based on the reception quality of the reference signal is considered, so that the idle RB allocated to the second device can be determined more accurately, thereby facilitating enhancement of uplink coverage capability.

In some embodiments, the step S23 includes:

In some embodiments, said determining a scheduling value for scheduling the idle RB by the second device according to the channel quality and the weight coefficient comprises:

and determining a scheduling value of the second equipment for scheduling the idle RB according to the product of the channel quality and the weight coefficient.

Of course, in other embodiments, if a fair ratio algorithm is used, the determining the scheduling value of the second device for scheduling the idle RB according to the product of the channel quality and the weight coefficient may be: determining a metric value based on the channel quality, wherein the metric value is: a ratio of a bit transmission rate of the idle RB at a current time slot to an average bit transmission rate of the idle RB within a predetermined number of time slots prior to the current time slot; and determining a scheduling value for the second device to schedule the idle RB according to the product of the metric value and the weight coefficient. Here, the predetermined number is a positive integer greater than or equal to 2.

In an embodiment, the sending, to the second device, resource scheduling information of the allocated idle RB according to the scheduling value includes:

and according to the scheduling value, determining to allocate the idle RB with the scheduling value larger than a preset scheduling threshold value to the second equipment, and sending resource scheduling information of the allocated idle RB to the second equipment.

Thus, in the embodiment of the present disclosure, the scheduling value of each idle RB scheduled by the second device may be determined according to the channel quality and the weight coefficient; determining that the second device can schedule the free RB in response to a scheduling value of the second device scheduling the free RB exceeding a certain threshold.

Here, the weight coefficient is positively correlated with the scheduling value; that is, the greater the scheduling value, the greater the weight coefficient, indicating a greater probability of being assigned to an idle RB.

In an embodiment, the channel bandwidth is a carrier bandwidth of the second device. For example, the channel bandwidth is an uplink carrier bandwidth of the second device.

Here, the network in which the second device is located may be a fifth generation communication technology (5G) network or a fourth generation communication technology (4G) network.

For example, as shown in fig. 3, the total system bandwidth in a 5G network system is BW; the carrier bandwidth allocated to the second device i is BW_iThe carrier bandwidth allocated to the second device j is BWj. Thus, in this example, the channel bandwidth is BW for the second device i_i(ii) a For the second device j, the channel bandwidth is BWj.

Here, the system bandwidth is a total idle bandwidth of a network in which the second device is located. The middle position RB is the middle RB, and the edge position RB is the edge RB.

In another embodiment, the channel bandwidth is a system Bandwidth (BW) or a system bandwidth part (BWP).

Here, the network in which the second device is located may be a 4G or third generation communication technology (3G) network, and the like.

For example, as shown in fig. 4, the system bandwidth in the 4G network system is BW. Thus, in this example, the channel bandwidth of the second device is BW.

Here, according to the position of the idle RB in the channel bandwidth, the idle RB includes: middle RB and edge RB; the edge RB includes: an edge RB of a higher frequency than the middle RB, and an edge RB of a lower frequency than the middle RB.

For example, referring again to fig. 4, the channel bandwidth may be divided into M resource blocks RB, and the positions of the resource blocks RB in the channel bandwidth may be numbered by numbers or letters. For example, the positions of M RBs are numbered as 0, 1, 2, … …, C, … … and M-1; wherein M is a positive integer greater than 1. Here, RB at position 0₀And RB at position M-1_M-1May both be edge RB; RB of position C_CMay be the middle RB. Alternatively, it may be close to RB₀And RB_M-1At least one or more RBs of (a) are intermediate RBs; or close to RB_CIs an edge RB. Here, C is greater than or equal to 0 and less than or equal to M.

In the above example, in response to M being equal to 49, the channel bandwidth may be divided into 50 RBs; the positions of the 50 RBs are respectively numbered as 0, 1, 2, … and 50. Here, positions that can be numbers 10 to 14, and 35 to 19 are edge positions, and their corresponding RBs are edge RBs; positions numbered 15 to 34 are intermediate positions, and the corresponding RB is an intermediate RB.

Here, one position-numbered RB may be one or more.

Here, the one RB is a predetermined number of subcarriers. For example, the predetermined number is 12.

In this way, in the embodiment of the present disclosure, the weight coefficient for allocating each idle RB by the second device may be determined according to the path loss and the position of the idle RB in the channel bandwidth. Therefore, the influence of the position of the RB on the maximum power back-off is considered, and the influence of the position of the RB on the uplink power control is further considered, so that the scheduling value can be determined more accurately, and the realization of more accurate scheduling of idle RB resources is facilitated.

As shown in fig. 5, in some embodiments, the determining, according to the path loss and the positions of the idle RBs in the channel bandwidth, a weight coefficient allocated to each idle RB for the second device includes:

step S221: determining a first weight factor of the second device according to the path loss;

step S222: determining a second weight factor of the idle RB according to the position of the idle RB in a channel bandwidth;

step S223: determining the weight coefficient of the second device at the idle RB based on the first weight factor and the second weight factor.

In the embodiment of the present disclosure, different path losses correspond to different first weight factors; the positions of the different RBs in the channel bandwidth correspond to different second weighting factors.

For example, in one embodiment, the second weight factor of the middle RB is different from the second weight factor of the edge RB. In another embodiment, the second weight factor of the middle RB is greater than the second weight factor of the edge RB.

Here, one way to implement step S221 is:

the path loss is positively correlated with the first weight factor; i.e. the larger the path loss, the larger the first weighting factor.

And determining the first weight factor for the second equipment from large to small according to the sequence of the path loss of the second equipment from high to low. For example, in one embodiment, the path losses of the N second devices are X respectively₁、X₂、X₃、……、X_NThe first weighting factors respectively correspond to: e₁、E₂、E₃、……、E_N(ii) a If X₁＞X₂、＞X₃、……、＞X_NThen E is₁＞E₂＞E₃、……、＞E_N(ii) a Wherein N is 1 or moreA positive integer.

In an embodiment of the disclosure, the first weight factor of the second device increases with increasing path loss based on a corresponding attenuation parameter; alternatively, the first weight factor of the second device decreases as the path loss decreases based on a corresponding attenuation parameter.

Here, one way to implement step S222 is to:

the second sub-weight factors determined for the idle RBs are from large to small based on the order of the positions of the idle RBs in the channel bandwidth from the middle to the edge; i.e. the second weight factor decreases gradually from the middle of the channel bandwidth to the edge idle RB.

In some embodiments, the step S223 includes:

determining the weight factor of the second device at the idle RB based on a product of the first weight factor and the second weight factor.

In other embodiments, step S223 includes:

determining the weight factor of the second device at the idle RB based on a sum of the first weight factor and the second weight factor.

In the embodiment of the present disclosure, a first weighting factor may be determined according to a path loss, a second weighting factor may be determined according to a position of the idle RB in a channel bandwidth, and a weighting coefficient of the second device in the idle RB may be determined based on the first weighting factor and the second weighting factor. Therefore, the influence of the path loss and the position of the idle RB in the channel bandwidth on the weight coefficient is considered, so that the obtained scheduling value is more accurate, and the corresponding idle RB can be more reasonably distributed to each second device.

Moreover, in the embodiment of the present disclosure, since the larger the path loss is, the larger the determined first weighting factor is, the smaller the path loss is, the smaller the determined first weighting factor is; the position of the idle RB is more in the middle of the channel bandwidth, the determined second weight factor is larger, and the position of the idle RB is more in the edge of the channel bandwidth, the determined second weight factor is smaller. In this way, the second device with larger path loss can allocate idle RBs at the middle position of the channel bandwidth as much as possible; in this way, the maximum power back-off of the second device for transmitting signals can be reduced, and the uplink coverage capability of the cell can be increased. And moreover, the maximum power back-off is reduced, so that the power amplification efficiency of the second equipment can be improved, and the energy conservation of the second equipment is facilitated.

Of course, the second device with smaller path loss may also allocate the idle RB at the edge of the channel bandwidth; thus, the RB in the whole channel bandwidth can be reasonably called.

As shown in fig. 6, in some embodiments, the determining, according to the pathloss and the position of the idle RB in the channel bandwidth, a weight coefficient allocated to each idle RB by the second device includes:

step S224: in response to the path losses of the N second devices being greater than or equal to a predetermined path loss threshold, determining that the weight coefficients of the N second devices in the middle RB are all greater than a predetermined weight value; wherein N is a positive integer greater than or equal to 1;

In one embodiment, the middle RB is an inner zone RB; the edge RB is an outer region RB; the inner zone RB is an RB with Maximum Power Reduction (MPR) smaller than a preset Maximum Power Reduction threshold; the outer region RB is an RB in which the MPR is greater than or equal to the predetermined maximum power back-off threshold.

In one embodiment, the predetermined weight value is 1.

Referring again to fig. 6, in other embodiments, the determining, according to the path loss and the position of the idle RB in the channel bandwidth, a weight coefficient allocated to each idle RB by the second device further includes:

step S225: determining that the weight coefficients of the N second devices at the edge RB are all predetermined weight values in response to the path losses of the N second devices being less than the predetermined path loss threshold.

In this way, in the embodiment of the present disclosure, the second device with the path loss greater than the predetermined path loss threshold may be prioritized to invoke the intermediate RB, so that the maximum power back-off of the signal transmitted by the second device can be reduced, and the uplink coverage capability of the cell can be increased. And moreover, because the maximum power back-off is reduced, the power amplification efficiency of the second equipment can be improved, and the energy conservation of the second equipment is facilitated.

To facilitate understanding of the above-described embodiments of the present disclosure, the following examples are given as examples herein.

Example one

As shown in fig. 7, a processing method of resource allocation is disclosed, the method includes the following steps:

step S31: receiving a reference signal of a second device;

optionally, the first device receives reference signals of N second devices, where N is a positive integer greater than or equal to 1.

Here, the first device is a base station or a user equipment.

Here, the N second devices are numbered in sequence as: 1. 2, … …, i, … …, N; wherein i is a positive integer greater than or equal to 1 and less than or equal to N.

Step S321: determining the channel quality transmitted by the second device on an idle RB according to the receiving quality of the reference signal;

optionally, the first device determines, according to a signal-to-noise ratio in the reception quality of the reference signal, a channel quality of transmission on an idle RB by the second device.

Step S322: determining a path loss of the second device according to the reception quality;

Step S33: determining a first weight factor of the second device according to the path loss;

optionally, the first device determines a first weight factor of the second device according to the path loss; wherein the path loss is positively correlated with the first weight factor.

optionally, the first device determines a second weighting factor of the idle RB according to a position of the idle RB in a channel bandwidth; wherein the second weight factor decreases gradually from the middle of the channel bandwidth to the edge free RB.

Step S35: determining a weight coefficient of the second device in the idle RB according to the first weight factor and the second weight factor;

optionally, the first device determines a weight coefficient of the second device in the idle RB according to a product of the first weight factor and the second weight factor.

For example, in response to the ith second device having a path loss of X_iThe first weight factor of the ith second device is E_iAnd the second weight coefficient of the free RB at the C position is F_CThe weighting factor W of the ith second device_i＝E_i×F_c。

Here, the weight coefficient is maximized when the second device responding to the maximum path loss allocates the free RB of the most middle position.

Step S36: determining a scheduling value of the second equipment for scheduling the idle RB according to the channel quality and the weight coefficient;

optionally, the first device determines a metric value according to the channel quality; wherein the metric value is: a ratio of a bit transmission rate of the idle RB at a current time slot to an average bit transmission rate of the idle RB within a predetermined number of time slots prior to the current time slot; and determining a scheduling value for the second device to schedule the idle RBs based on the metric value and the weight system.

Here, the predetermined number is a positive integer greater than or equal to 2. For example, the predetermined number is 10.

Step S37: and sending the resource scheduling information of the allocated idle RB to the second equipment according to the scheduling value.

Optionally, the first device sends, to the second device, resource scheduling information of one or more idle RBs of which the scheduling value is greater than a predetermined scheduling threshold according to the scheduling value.

In the embodiment of the present disclosure, the scheduling value for scheduling the RB may be determined according to the channel quality transmitted by the second device on the idle RB, i.e., according to the quality of the channel, and according to the weight coefficient for allocating the idle RB to the second device based on the reception quality, i.e., considering the probability that the second device can be scheduled in a matching manner with each idle RB; therefore, the idle RB allocated to the second equipment can be more accurately determined, and the uplink coverage capability can be enhanced.

In addition, in the embodiment of the present disclosure, when the path loss of the second device is relatively large, that is, the second device at the edge of the cell, the idle RB in the middle of the channel bandwidth may be allocated as soon as possible. Therefore, on one hand, the maximum power of the signal transmitted by the second equipment can be reduced, so that the uplink coverage capability of the cell can be increased; on the other hand, the maximum power back-off is reduced, so that the efficiency of the power amplifier of the second equipment can be improved, and the energy conservation of the second equipment is facilitated.

In addition, in the embodiment of the present disclosure, when the path loss of the second device is relatively small, that is, when the channel quality is relatively good, the second device in the middle of the cell may also allocate an idle RB at the edge of the channel bandwidth to the second device; thereby facilitating the RBs in the entire channel bandwidth to be properly called.

As shown in fig. 8, a processing method for resource allocation is disclosed, which is applied to a first device, and the method includes the following steps:

step S41, step S421 and step S422 correspond to the contents of step S31, step S321 and step S322 in the first example.

Step S43: determining a weight coefficient of each idle RB distributed by the second equipment according to the path loss and the position of the idle RB in a channel bandwidth;

wherein, the step S43 includes:

step S431: determining that the weight coefficient of the second device at an intermediate RB is greater than a predetermined weight value in response to the path loss being greater than or equal to a predetermined path loss threshold.

Here, the weight coefficients of the second devices corresponding to different path losses in the intermediate RB are different.

Here, the weight coefficients of the N second devices in the same intermediate RB increase as the path loss increases based on the corresponding attenuation parameters; the weight coefficients of the N second devices in the same middle RB decrease as the path loss decreases based on corresponding attenuation parameters.

Please refer to fig. 4, RB at position number C_CIs the middle RB.

In one embodimentIn the system, the path losses of the N second devices are respectively X₁、X₂、X₃、……、X_NThe weight coefficients corresponding to the intermediate RBs are W₁、W₂、W₃、……、W_N(ii) a If the X is₁＞X₂、＞X₃、……、＞X_N≥X_yzThen W is₁＞W₂＞W₃、……、＞W_N≥W_yz(ii) a Wherein, X is_yzFor a predetermined path loss threshold, W_yzIs a predetermined weight value.

In one embodiment, the predetermined weight value is 1.

Of course, in other embodiments, the weight factor of the second device in the middle RB is also gradually decreased from the middle to the edge of the channel bandwidth.

step S432: determining the weight coefficient of the second device at an edge RB as the predetermined weight value in response to the path loss being less than a predetermined path loss threshold.

Please refer to fig. 4, RB at position number 0₀And RB numbering the M-1 position_M-1Is the edge RB.

In one embodiment, the path losses of the N second devices are X respectively₁、X₂、X₃、……、X_NAnd if the weight coefficients of the N second devices at the edge RB are all smaller than the predetermined path loss threshold, the weight coefficients are all predetermined weight values.

Step S44 and step S45 correspond to the contents of step S36 and step S37, respectively, in the first example.

In the embodiment of the present disclosure, the second device with a large path loss may schedule the middle RB as much as possible; therefore, on one hand, the maximum power back-off of the signal transmitted by the second equipment is reduced, so that the uplink coverage capability of the cell can be increased; on the other hand, the maximum power back-off is reduced, so that the efficiency of the power amplifier of the second equipment can be improved, and the energy conservation of the second equipment is facilitated.
