Detailed Description

The present invention will be described in further detail with reference to the drawings and examples.

Currently, in a 4G system, when data transmission is performed, uplink or downlink time-frequency domain physical resources may be grouped into RBs, and the RBs are used as a physical resource unit for scheduling and allocation. For example, when the network device needs to perform uplink scheduling on the terminal, the terminal may be allocated with a corresponding RB, so that the terminal can perform uplink signal transmission using the allocated RB.

In the foregoing manner, in order to satisfy radio frequency indexes such as EVM, adjacent channel leakage ratio (ALCR), spectrum template (SEM), and Spurious Emission (SM), the power required to be backed off when the terminal performs uplink signal transmission is large, so that the transmission power of the terminal is reduced, and the uplink coverage performance is further reduced.

Based on this, in the embodiment of the present invention, an RB is allocated to a control channel of a terminal; the allocated RB is an inner RB within the corresponding channel bandwidth. And selecting the allocated RB as an inner RB or an outer RB for the PUSCH based on the transmitting power, the power level and the modulation mode of the terminal.

An embodiment of the present invention provides a resource allocation method, which is applied to a first network device, and as shown in fig. 1, the method includes:

step 101: allocating RBs for control channels of the terminals; the allocated RB is an inner RB within the corresponding channel bandwidth.

Here, the first network device may refer to a base station, a Control Unit (CU), and a Distributed Unit (DU). In a fifth Generation mobile communication (5g, first Generation) system, the base station may be a next Generation node B (gNB).

Here, the Control Channel may refer to a Physical Uplink Control Channel (PUCCH) or a Physical Random Access Channel (PRACH).

Here, the RB may refer to a resource block consisting of all OFDM symbols within one slot and 12 subcarriers in the frequency domain.

Here, in the 5G system, RBs can be classified into three categories, inner, edge, and outer. Wherein, the edge RB may refer to an RB which is located at the edge of the channel and has a continuous RB length of not more than 2 RBs; wherein the maximum number of RBs can be represented by NRB given a channel bandwidth and a subcarrier spacing. The contiguous RB length of the Inner RB is represented by LCRB, which is related to NRB by: LCRB ≦ ceil (NRB/2), and the starting RB position of Inner RB is denoted by (RBStart, low), where RBStart, low = max (1,floor (LCRB/2)), and the ending RB position of Inner RB is denoted by (RBStart, high), where RBStart, high = NRB-RBStart, low-LCRB. The RBs except edge RB and inner RB are Outer RB. FIG. 2 is a schematic diagram of inner RB, outer RB and edge RB.

Tables 1 and 2 show the MPR indices of inner RB, outer RB and edge RB. Table 1 shows MPR indexes of an inner RB, an outer RB, and an edge RB obtained by testing power required to be backed-off when a terminal of power class 3 performs uplink signal transmission using different types of RBs. Table 2 shows MPR indexes of inner RB, outer RB, and edge RB obtained by testing power required to be backed off when a terminal of power class 2 performs uplink signal transmission using different types of RBs. As can be seen from tables 1 and 2, the terminal needs the minimum power for backoff in uplink signal transmission using the inner RB. For example, the power required to be backed off when the terminal with the power level 2 performs uplink signal transmission by using the edge RB and adopting the DFT-S-OFDM PI/2 modulation mode is 3.5dB, the power required to be backed off when the terminal performs uplink signal transmission by using the outer RB and adopting the DFT-S-OFDM PI/2 modulation mode is 0.5dB, and the power required to be backed off when the terminal performs uplink signal transmission by using the inner RB and adopting the DFT-S-OFDM PI/2 modulation mode is 0dB.

TABLE 1

TABLE 2

In practical application, considering that the difference between the values of the MPRs corresponding to the inner RB and the non-inner RB exists, that is, the MPR value corresponding to the inner RB is the minimum, in this way, the first network device may allocate the inner RB to the control channel of the terminal, so that the terminal can implement power backoff through the minimum MPR value, and further, uplink coverage performance can be improved.

Specifically, the first network device may allocate inner RB to PUCCH and PRACH of the terminal in a semi-static allocation manner, so that allocation of edge RB and outer RB to PUCCH and PRACH of the terminal may be avoided, and reduction of transmission power of the terminal by reducing power required to be backed off is avoided, thereby improving uplink coverage performance. The semi-static allocation method may be that only one inner RB needs to be allocated to the PUCCH and the PRACH of the terminal, and then the terminal may be reused.

In practical application, when channel bandwidths corresponding to control channels of terminals are different, the number of inner RBs required by the terminals for uplink signal transmission is also different, and thus, the network device may further configure the number of inner RBs.

Based on this, in an embodiment, when allocating an inner RB for a control channel of a terminal, the method further includes: configuring the number of inner RBs.

Here, the number of inner RBs may be configured according to a channel bandwidth corresponding to a control channel of a terminal. Table 3 is a correspondence of channel bandwidth to the number of inner RBs.

For example, assuming that the PUCCH of the terminal corresponds to a channel bandwidth of 1.4MHz, looking up table 3, the number of inner RBs is 1, and thus, the network device may configure the number of inner RBs as 1. Assuming that the channel bandwidth corresponding to the PRACH of the terminal is 5MHz, looking up table 3, the number of inner RBs obtained is 8, and thus, the network device may configure the number of inner RBs to be 8.

Channel bandwidth	inner RB number
		1.4MHz	1
3MHz	4
		5MHz	8

TABLE 3

Step 102: transmitting an inner RB allocated for a control channel of a terminal to the terminal.

Here, the inner RB allocated to the control channel of the terminal is sent to the terminal, so that the terminal can perform uplink signal transmission by using the allocated inner RB, for example, the terminal may send the cell level parameters to the first network device by using the inner RB allocated to the PRACH.

By adopting the technical scheme provided by the embodiment of the invention, the first network equipment allocates the inner RB for the control channel of the terminal, so that the power required for backing back when the terminal carries out uplink signal transmission is smaller, the transmission power of the terminal cannot be reduced too much, and the uplink coverage performance can be improved.

An embodiment of the present invention provides a resource allocation method, which is applied to a second network device, and as shown in fig. 3, the method includes:

step 301: and selecting the allocated RB as an inner RB or an outer RB for the PUSCH based on the transmission power, the power level and the modulation mode of the terminal.

The Modulation scheme may include Quadrature Phase Shift Keying (QPSK), quadrature Amplitude Modulation (QAM), and the like. The power level may be determined according to a communication system of the terminal, for example, the power level 4 corresponding to GSM/GPRS 850/900; GSM/GPRS1800/1900 corresponds to power class 1, and so on.

In practical application, in order to select the allocated RB as an inner RB or an outer RB for the PUSCH based on the transmission power, the power level, and the modulation mode of the terminal, the second network device needs to estimate the transmission power of the terminal.

Based on this, in an embodiment, the method may further include: and estimating the transmitting power of the terminal.

Here, the second network device may estimate the transmit Power of the terminal based on a Power Headroom Report (PHR) reported by the terminal; or, the second network device may estimate the transmit power of the terminal based on a Modulation and Coding Scheme (MCS) and a Physical Resource Block (PRB) used by the terminal for performing the transmission using the PUSCH.

In practical application, since the maximum transmission power of the terminal is affected by the size of the MPR value, when the transmission power of the terminal reaches full power transmission, the uplink coverage performance is affected by the difference between the MPR values corresponding to the inner RB and the MPR values corresponding to the non-inner RB.

Based on this, in an embodiment, the selecting the RB to be allocated for the PUSCH as an inner RB or an outer RB based on the transmission power, the power level, and the modulation scheme of the terminal includes: judging whether the transmitting power of the terminal is equal to the maximum transmitting power configured for the terminal by the second network equipment; and when the transmission power of the terminal is determined to be equal to the maximum transmission power configured for the terminal by the second network equipment, selecting the allocated RB as an inner RB or an outer RB for the PUSCH based on the obtained power level and modulation mode of the terminal.

In practical application, whether the MPR values of the inner RB and the non-inner RB have a difference is related to the power level and the modulation scheme of the terminal, so that the second network device may obtain the power level and the modulation scheme of the terminal, and determine whether the MPR values of the inner RB and the non-inner RB have a difference based on the obtained power level and the modulation scheme of the terminal.

Based on this, in an embodiment, the selecting the allocated RB for the PUSCH to be an inner RB or an outer RB based on the obtained power level and modulation scheme of the terminal includes: judging whether the values of the MPRs corresponding to the inner RB and the non-inner RB are the same or not based on the obtained power level and the modulation mode of the terminal; when the numerical value of the MPR corresponding to the inner RB and the non-inner RB is determined to be different, the RB selected to be distributed for the PUSCH is the inner RB; and when the value of the MPR corresponding to the inner RB and the non-inner RB is determined to be the same, selecting the RB to be allocated for the PUSCH as the outer RB.

Here, the second network device may dynamically select an RB allocated for a PUSCH of a terminal as an inner RB or an outer RB.

For example, when it is determined that the transmission power of the terminal is equal to the maximum transmission power configured for the terminal by the second network device, if there is a gap between the MPR values of inner RB and non-inner RB, inner RB is allocated for PUSCH; otherwise, allocating outer RB for PUSCH.

In practical application, in order to determine whether there is a difference between the MPR values of the inner RB and the non-inner RB based on the power level and the modulation mode of the terminal, the second network device may establish a resource difference table, where a corresponding relationship between the power level, the modulation mode, and the resource difference value of the terminal is stored in the resource difference table.

Based on this, in an embodiment, the determining whether the value of the MPR corresponding to the inner RB is the same as the value of the MPR corresponding to the non-inner RB based on the obtained power level and the obtained modulation scheme of the terminal includes: based on the obtained power grade and the modulation mode of the terminal, searching a first resource difference value corresponding to the power grade and the modulation mode from a resource difference table; the resource difference table stores the corresponding relation between the power grade of the terminal, the modulation mode and the resource difference value; judging whether the first resource difference value is equal to a preset threshold value or not; when the first resource difference value is determined to be equal to a preset threshold value, determining that the numerical values of MPRs corresponding to an inner RB and a non-inner RB are different; otherwise, determining that the value of the MPR corresponding to the inner RB and the non-inner RB is the same.

Table 4 is an established resource difference table, and as shown in table 4, the resource difference table stores the correspondence between the power level of the terminal, the modulation method, and the resource difference value. For example, assuming that the modulation scheme is DFT-s-OFDM QPSK, the power level of the terminal is power level 2, and querying the resource difference table may query that the first resource difference value is Y, where "Y" represents that there is a difference between MPR values of inner RB and non-inner RB. Assuming that the modulation mode is DFT-s-OFDM 256QAM, the power level of the terminal is power level 2, and querying the resource difference table may query that the first resource difference value is N, where "N" represents that there is no difference between the MPR values of inner RB and non-inner RB.

TABLE 3

For example, suppose that the second network device needs to perform uplink scheduling on terminal a and terminal B at a certain time. Assuming that the terminal a is located in a cell close to the second network device, so that the PHR reported by the terminal a to the second network device is large, assuming that the modulation mode adopted by the terminal a is CP-OFDM 64QAM or CP-OFDM 256QAM, after the second network device obtains the power level and the modulation mode of the terminal a, querying the resource difference table, and querying that the first resource difference value is N, where "N" represents that there is no difference between MPR values of an inner RB and a non-inner RB, so that when the second network device allocates RBs for PUSCH, it is not necessary to consider the difference between the inner RB and the non-inner RB. Assuming that the terminal B is located in a cell far away from the second network device, and the PHR reported by the terminal B to the second network device is small, and assuming that the modulation mode adopted by the terminal B is CP-OFDM or DFT-S-OFDM, after the network device obtains the power class and the modulation mode of the terminal B, the resource difference table is queried, and it can be queried that the first resource difference value is Y, where "Y" represents that a difference exists between MPR values of inner RB and non-inner RB. In this way, the second network device preferentially allocates the inner RB to the PUSCH, avoiding using the edge RB.

Step 302: and sending an inner RB or outer RB allocated for the PUSCH of the terminal to the terminal.

Here, the inner RB or outer RB allocated for the PUSCH of the terminal is transmitted to the terminal, so that the terminal can perform uplink signal transmission using the allocated inner RB or outer RB, for example, the terminal may transmit the cell level parameters to the second network device using the inner RB or outer RB allocated for the PRACH.

By adopting the technical scheme provided by the embodiment of the invention, the second network equipment selects the RB allocated for the PUSCH of the terminal as the inner RB or the outer RB, in other words, the second network equipment preferentially allocates the inner RB and forbids allocation of the edge RB for the PUSCH of the terminal. Therefore, when the terminal transmits the uplink signal, the power back-off of the edge user can be reduced, the uplink power of the terminal can be fully exerted, and the uplink coverage performance of the system can be improved.

To implement the method according to the embodiment of the present invention, an embodiment of the present invention further provides a resource allocation apparatus, which is disposed on a first network device, and as shown in fig. 4, the apparatus includes:

a first allocation unit 41 configured to allocate RBs for control channels of terminals; the allocated RB is an inner RB within the corresponding channel bandwidth.

A first transmitting unit 42, configured to transmit an inner RB allocated for a control channel of a terminal to the terminal.

Here, the first network device may refer to a base station, CU, DU. In a 5G system, the base station may be a next generation node B (gNB).

Here, the control channel may refer to a Physical Uplink Control Channel (PUCCH), a Physical Random Access Channel (PRACH).

Here, in the 5G system, RBs can be classified into three categories, inner, edge, and outer.

In practical application, considering that the difference exists between the values of the MPRs corresponding to the inner RB and the MPRs corresponding to the non-inner RB, that is, the MPR value corresponding to the inner RB is the minimum, the base station can allocate the inner RB to the control channel of the terminal, so that the terminal can implement power backoff through the minimum MPR value, and the uplink coverage performance can be improved.

Based on this, when allocating inner RBs for the control channel of the terminal, the first allocating unit 41 is further configured to allocate the number of inner RBs.

Here, the number of inner RBs may be configured according to a channel bandwidth corresponding to a control channel of a terminal.

Here, the inner RB allocated to the control channel of the terminal is sent to the terminal, so that the terminal can perform uplink signal transmission by using the allocated inner RB, for example, the terminal may send the cell-level parameters to the first network device by using the inner RB allocated to the PRACH.

In practical applications, the first allocating unit 41 may be implemented by a processor in a resource allocating device, and the first sending unit 42 may be implemented by a communication interface in the resource allocating device.

In order to implement the method according to the embodiment of the present invention, an embodiment of the present invention further provides a resource allocation apparatus, which is disposed on a second network device, and as shown in fig. 5, the apparatus includes:

the second allocating unit 51 is configured to select an RB allocated to the PUSCH as an inner RB or an outer RB based on the transmission power, the power level, and the modulation scheme of the terminal.

A second transmitting unit 52, configured to transmit an inner RB or an outer RB allocated for a PUSCH of a terminal to the terminal.

Based on this, in an embodiment, the apparatus further comprises: and the estimation unit is used for estimating the transmitting power of the terminal.

Here, the second network device may predict the transmit power of the terminal based on the PHR reported by the terminal; or, the second network device may estimate the transmit power of the terminal based on the MCS and the PRB used by the terminal for the current transmission using the PUSCH.

In practical application, since the maximum transmission power of the terminal is affected by the size of the MPR value, when the transmission power of the terminal reaches full power transmission, the uplink coverage performance is affected by the difference between the MPRs corresponding to the inner RB and the MPR corresponding to the non-inner RB.

Based on this, in an embodiment, the second allocating unit 51 is specifically configured to determine whether the transmission power of the terminal is equal to the maximum transmission power configured for the terminal by the second network device; and when the transmission power of the terminal is determined to be equal to the maximum transmission power configured for the terminal by the second network equipment, selecting the allocated RB as an inner RB or an outer RB for the PUSCH based on the obtained power level and modulation mode of the terminal.

Based on this, in an embodiment, the second allocating unit 51 is specifically configured to determine whether the values of the maximum power back-off MPRs corresponding to the inner RB and the non-inner RB are the same based on the obtained power level and the modulation mode of the terminal; when the value of the MPR corresponding to the inner RB and the non-inner RB is determined to be different, the RB selected and distributed for the PUSCH is the inner RB; and when the value of the MPR corresponding to the inner RB and the non-inner RB is determined to be the same, selecting the RB to be allocated for the PUSCH as the outer RB.

Based on this, in an embodiment, the second allocating unit 51 is specifically configured to search, based on the obtained power level and modulation scheme of the terminal, a first resource difference value corresponding to the power level and the modulation scheme from a resource difference table; the resource difference table stores the corresponding relation of the power grade, the modulation mode and the resource difference value of the terminal; judging whether the first resource difference value is equal to a preset threshold value or not; when the first resource difference value is determined to be equal to a preset threshold value, determining that the numerical values of MPRs corresponding to an inner RB and a non-inner RB are different; otherwise, determining that the value of the MPR corresponding to the inner RB and the non-inner RB is the same.

Here, the inner RB or outer RB allocated for the PUSCH of the terminal is sent to the terminal, so that the terminal can perform uplink signal transmission by using the allocated inner RB or outer RB, for example, the terminal may send the cell level parameter to the second network device by using the inner RB or outer RB allocated for the PRACH.

In practice, the second allocating unit 51 and the pre-estimating unit may be implemented by a processor in the resource allocating device, and the second sending unit 52 may be implemented by a communication interface in the resource allocating device.

An embodiment of the present invention further provides a first network device, as shown in fig. 6, where the first network device 60 includes: a first communication interface 61, a first processor 62, a first memory 63; wherein,
