As shown in Figure 2, an embodiment of the present disclosure provides a resource processing method, which is executed by a base station. The method includes:

S1110: In response to allocating resources to the first type of terminal, resource allocation is performed according to the bandwidth supported by the first type of terminal.

The resource processing method may include allocating resources by the base station to the first type of terminal.

The base station includes but is not limited to an evolved base station (eNB) and/or a next-generation base station (gNB).

For example, the first type of terminal may be a RedCap terminal or an enhanced eRedCap terminal.

As another example, the transceiver bandwidth supported by the first type of terminal may be 20 MHz or even 5 MHz.

Of course, the above is just an example of the first type of terminal, and the specific implementation is not limited to the above example.

Terminals capable of communicating with the terminal may also include: a second type of terminal, which is different from the first type of terminal. For example, the bandwidth supported by the second type of terminal is greater than the bandwidth supported by the first type of terminal. Illustratively, the second type of terminal includes, but is not limited to, enhanced Mobile Broadband (eMBB) terminals.

When allocating resources to the first type of terminal, the resources will be allocated according to the bandwidth supported by the first type of terminal. The resource allocation here includes: frequency domain resource allocation according to the bandwidth supported by the first type of terminal.

For example, allocating resources according to the bandwidth supported by the first type of terminal may include: determining the bandwidth of the activated BWP or initial BWP of the first type of terminal according to the bandwidth supported by the first type of terminal. Also for example, according to the bandwidth supported by the first type of terminal, the number of resource blocks (Resource Block, RB) allocated to the first type of terminal at one time is determined. This RB can also be called a Physical Resource Block (PRB).

In the embodiment of the present disclosure, there are many ways to allocate resources to the first type of terminal, which may specifically include:

Type (Type) 0, a non-continuous allocation method of frequency domain resources;

Type 1, a continuous allocation method of frequency domain resources.

In this embodiment of the present disclosure, the S1110 may include: responding to using Type 1 to allocate resources to the first type of terminal, and allocating resources according to the bandwidth supported by the first type of terminal.

Using this method to allocate resources to the first type of terminals can, on the one hand, enable the first type of terminals to transmit data on the resources allocated to them without frequently switching the central frequency point of operation. On the other hand, according to the requirements of the first type of terminals, When resources are allocated with the supported bandwidth, fewer bits are required for resource allocation information, thereby reducing the bit overhead of resource allocation.

As shown in Figure 3, an embodiment of the present disclosure provides a resource processing method, which is executed by a base station. The method includes:

S1210: In response to allocating resources for the first type of terminal, determine the number of RBs that can be included in the bandwidth part BWP configured for the first type of terminal according to the first bandwidth supported by the first type of terminal; wherein, the first bandwidth It is determined based on the maximum frequency range that the first type of terminal can receive or transmit.

The first bandwidth capability of the first type terminal includes but is not limited to: the transceiving bandwidth of the first type terminal. The transceiver bandwidth may be: the maximum operating bandwidth of the radio frequency structure of the first type terminal. For example, the transceiving bandwidth of the first type of terminal may be the maximum bandwidth supported by the antenna included in the first type of terminal.

If the working BWP (also called activated BWP or initial BWP) of the first type terminal is determined based on the first bandwidth capability of the first type terminal, once the BWP is determined, there is no need for resource allocation information to separately indicate the number of RBs included in the allocated BWP. , thus reducing the bit overhead.

As shown in Figure 4, an embodiment of the present disclosure provides a resource processing method, which is executed by a base station. The method includes:

S1310: In response to allocating resources to the first type of terminal, allocate the number of RBs for data transmission to the first type of terminal according to the second bandwidth supported by the first type of terminal; wherein the second bandwidth is based on the second bandwidth supported by the first type of terminal. The maximum number of processing RBs supported by the first type of terminal for data transmission is determined.

This resource processing method can be executed alone or in combination with the technical solutions provided in any of the foregoing embodiments.

The second bandwidth supported by the first type of terminal includes but is not limited to: the baseband processing bandwidth of the first type of terminal.

For example, the processing bandwidth of the baseband processor of the first type of terminal may be the baseband processing bandwidth.

If the number of RBs is allocated according to the second bandwidth supported by the first terminal, subsequent resource allocation information does not need to additionally indicate the number of RBs allocated to the first type of terminal each time or reduce the number of bits required to indicate the number of RBs allocated to each resource allocation. , thereby reducing bit overhead.

If the number of one-time RBs is scheduled according to the second bandwidth supported by the first type of terminal, efficient data processing by the first type of terminal is facilitated.

For example, the number of RBs allocated by the first type terminal for data transmission is less than or equal to the second bandwidth supported by the first type terminal.

In the embodiment of the present disclosure, if the number of RBs allocated to the first type terminal for data transmission is less than or equal to the second bandwidth supported by the first type terminal, the bandwidth allocated to the first type terminal at one time can be reduced. Large, resulting in large encoding and decoding delays for the first type of terminal.

As shown in Figure 5, an embodiment of the present disclosure provides a resource processing method, which is executed by a base station. The method includes:

S1410: In response to allocating resources to the first type of terminal, resource allocation is performed according to the bandwidth supported by the first type of terminal.

S1420: Use the resource indicator RIV to jointly indicate the starting RB number S and the number of continuously distributed RBs L allocated to the first type of terminal.

In this embodiment of the present disclosure, type 1 is used to allocate resources to the first type of terminal. Therefore, the RBs allocated for data transmission for the first type terminal on the active BWP of the first type terminal will be continuously distributed.

After the resources are allocated to the first type terminal, the RIV will be used to jointly indicate the number S of the starting RB allocated to the first type terminal and the number of continuously allocated RBs.

For example, the RIV can be a resource index. This resource index simultaneously corresponds to a starting RB number S and the number (or length) of RBs L. The RIV corresponds to the RB number S and the number of RBs. The corresponding relationship between L can be specified by the protocol or written in advance into the first type terminal and the base station.

In this way, when the base station uses RIV to indicate the resources allocated to the first type terminal, it can determine the RIV that needs to be issued based on the corresponding relationship and the starting numbers S and L of the RBs currently allocated to the first type terminal; and then The first type of terminal sends RIV.

It is worth noting that when the base station allocates resources to the first type of terminals, it can make full use of each RB according to the remaining RB status of the activated BWP for the first type of terminals, and can flexibly determine the location of the starting RB and the individual RB. number.

In this disclosed embodiment, all RIVs are determined based on BWP-size and Lmax. The BWP-size is the size of the BWP where the RB allocated to the first type terminal is located. Lmax is determined based on the second bandwidth supported by the first type of terminal. Further, the BWP-size is determined based on the first bandwidth supported by the first type of terminal.

Specifically, when the S is less than or equal to the difference between BWP-size and Lmax, the value of the RIV is: S*Lmax+L;

When the S is greater than the difference between BWP-size and Lmax, the value of the RIV is: (BWP-size-Lmax)*Lmax+{(Lmax-1)+(Lmax-2)+…+(Lmax- (S-(BWP-size-Lmax)))};

Wherein, the Lmax is the maximum number of RBs of the first type of terminal;

The L is the actual number of the first type terminal RB;

The BWP-size is the size of the BWP where the RB allocated to the first type terminal is located.

If the RB numbers on the BWP are 0 to BWP-size-1, the value range of S can be from 0 to BWP-size-2. In the embodiment of the present disclosure, if L RBs are allocated to the first type of terminal, the value range of S at this time is from 0 to BWP-size-2-L.

Lmax is the maximum number of RBs supported by the first type of terminal. For example, the Lmax may be determined according to the second bandwidth supported by the first type of terminal. For example, Lmax may be equal to the number of RBs corresponding to the second bandwidth supported by the first type of terminal, etc. Assuming that the second bandwidth supported by the first type of terminal is 5 MHz, the Lmax is equal to the downward rounding of the quotient between 5 MHz and the bandwidth value of a single RB.

The value of L is any positive integer.

BWP-size can be considered as the number of RBs included in the activated BWP for the first type of terminal work.

In the embodiment of the present disclosure, the base station and the first type of terminal may both know the conversion relationship between RIV and S and L. Then, after the base station completes resource allocation, the RIV can be determined based on the conversion relationship, and the first type terminal receives the The RIV then determines the S and L referred to by the current receiving RIV based on the conversion relationship, thereby knowing the RB allocated by the base station to the first type of terminal.

It can be seen that in the embodiment of the present disclosure, the RIV is determined based on Lmax, which has the characteristics of simple RIV numbering and small bit overhead.

In some embodiments, the BWP-size may be determined according to the first bandwidth supported by the first type of terminal. For example, BWP-size may be equal to the number of RBs corresponding to the first bandwidth supported by the first type of terminal. Assuming that the first bandwidth supported by the first type of terminal is 20 MHz, the BWP-size may be equal to 20 MHz, or the BWP-size may be the downward rounding of the quotient between 20 MHz and the bandwidth value of a single RB.

If S is greater than the difference between BWP-size and Lmax, it means that the number of remaining available RBs in the BWP is less than the number of Lmax, but these remaining RBs can still be allocated. At this time, the value of RIV can be based on the actual situation each time. The allocated (Lmax-1), (Lmax-2)...(Lmax-(S-(BWP-size-Lmax), etc. are related, therefore, the RIV at this time is (BWP-size-Lmax)*Lmax+{(Lmax -1)+(Lmax-2)+…+(Lmax-(S-(BWP-size-Lmax)))}.

In some embodiments, the method further includes:

S1430: Send downlink control information (Downlink Control Information, DCI) including the RIV.

The RIV is carried in DCI and sent to the first type of terminal. The DCI of the first type of terminal has the characteristics of good dynamics. In this way, after the resource allocation of the first type of terminal is completed, the DCI can be used flexibly and quickly to send the RIV to the third type of terminal. A type of terminal.

DCI belongs to physical layer signaling. In other embodiments, the RIV can also be carried in non-physical layer signaling. For example, the RIV can also be carried in MAC CE or RRC signaling. Of course, this is just an example, and the specific implementation is not limited to this example.

In some embodiments, the first type of terminal includes: enhanced capability reduced eRedCap terminal.

In some embodiments, the first type of terminal includes, but is not limited to, an eRedCap terminal, and may also be other types of terminals. For example, other types of terminals here include, but are not limited to, MTC terminals, etc.

As shown in Figure 6, an embodiment of the present disclosure provides a resource processing method, which is executed by a first-type terminal. The method includes:

S2110: Receive DCI including resource allocation information, where the resource allocation information indicates frequency domain resources allocated to the first type of terminal, where the frequency domain resources are supported by the first type of terminal. Bandwidth is determined.

The resource processing method can be executed by the first type terminal itself.

The first type of terminal will receive the resource allocation information carried in the DCI. The frequency domain resources indicated by the resource allocation information are allocated according to the bandwidth supported by the first type of terminal. If this resource allocation method is adopted, the bits consumed by the resource allocation information can be reduced, thereby reducing the bit overhead of DCI.

It is worth noting that in the embodiment of the present disclosure, the frequency domain resource allocation method may include type 0 and type 1. In this embodiment of the present disclosure, the frequency domain resource allocation method of the first type of terminal may adopt Type 1.

In some embodiments, the receiving DCI including resource allocation information includes:

Receive DCI including RIV, wherein the RIV jointly indicates the starting RB number S and the number of continuously distributed RBs L allocated by the base station to the first type terminal.

In this embodiment of the present disclosure, the DCI carries an RIV, and one RIV will simultaneously indicate the number S of the starting RB and the number L of continuously allocated RBs. In this way, after receiving the RIV, the first type of terminal determines S and L based on the RIV, and then determines the corresponding RB on its own working BWP as the RB scheduled by the base station for data transmission.

In some embodiments, the number of RBs included in the BWP of the first type terminal is determined based on the first bandwidth supported by the first type terminal, wherein the first bandwidth is determined based on the first bandwidth. The maximum frequency range that the terminal can receive or transmit is determined;

and / or,

The number of RBs allocated to the first type of terminal is less than or equal to the second bandwidth supported by the first type of terminal, wherein the second bandwidth is based on the maximum number of processing RBs supported by the first type of terminal for data transmission. definite.

In some embodiments, when the S is less than or equal to the difference between BWP-size and Lmax, the value of the RIV is: S*Lmax+L;

When the S is less than or equal to the difference between BWP-size and Lmax, the value of the RIV is: (BWP-size-Lmax)*Lmax+{(Lmax-1)+(Lmax-2)+…+( Lmax-(S-(BWP-size-Lmax)))};

Wherein, the Lmax is the maximum number of RBs of the first type of terminal;

The L is the actual number of the first type terminal RB;

Lmax is the maximum number of RBs supported by the first type of terminal. For example, the Lmax may be determined based on the second bandwidth supported by the first type of terminal. For example, Lmax may be equal to the number of RBs corresponding to the second bandwidth supported by the first type of terminal, etc. Assuming that the second bandwidth supported by the first type of terminal is 5 MHz, the Lmax is equal to the downward rounding of the quotient between 5 MHz and the bandwidth value of a single RB.

The value of L is any positive integer.

In the embodiment of the present disclosure, both the base station and the first type of terminal may know the conversion relationship between RIV and S and L. Then, after the base station completes the resource allocation, the RIV can be determined based on the conversion relationship, and the first type terminal receives the The RIV then determines the S and L referred to by the current receiving RIV based on the conversion relationship, thereby knowing the RB allocated by the base station to the first type of terminal.

In the New Radio (NR) communication system, the maximum resource that a terminal can allocate can be the same as the size of the BWP. Therefore, in the type 1 resource allocation method, the resource allocation amount supported by the terminal is equal to the bandwidth of the BWP.

However, the maximum allocated resources supported by eRedCap terminals are not equal to the width of the BWP allocated to the terminal. If the resource allocation instructions and DCI bits are still determined based on the BWP bandwidth at this time, the DCI overhead of the terminal will increase. .

In view of this, the type 1 resource allocation method of eRedCap terminals is enhanced to reduce DCI overhead.

Exemplarily, the response is a first type terminal, and resource allocation is determined based on the terminal's transceiver bandwidth and/or BWP bandwidth. The first type of terminal includes but is not limited to eRedCap terminal.

The frequency range (Range of Frequency, RF) transceiver bandwidth supported by the first type of terminal is different from the baseband processing bandwidth. For example, the RF transceiver bandwidth of the eRedCap terminal is 20MHz, and the baseband processing bandwidth can be 5MHz.

The starting RB allocated to the terminal can be any RB in the BWP, and the total number of consecutive RBs allocated to the terminal is not greater than the total number of RBs included in the baseband processing bandwidth of the terminal.

The resource allocation indication is jointly coded according to the transceiver bandwidth and/or the BWP bandwidth of the terminal, and the joint coding is used to indicate the starting RB allocated to the terminal and the number of consecutive RBs. This joint encoding is one type of RIV mentioned above.

The details are as follows: BWP_size is the total number of RBs included in the BWP, Lmax is the maximum number of continuously distributed RBs allocated to the terminal, and Lmax is determined by the baseband processing bandwidth of the terminal.

If S<=BWP_size-Lmax, then RIV=S*Lmax+L

If S>BWP_size-Lmax, then RIV=(BWP_size-Lmax)*Lmax+{(Lmax-1)+(Lmax-2)+…+(Lmax-(S-(BWP_size-Lmax)))

The number of bits occupied by the resource allocation domain in DCI can be determined by the baseband processing bandwidth of the terminal and the bandwidth of the BWP.

For example, the number of bits occupied by the resource allocation field can at least indicate the maximum index value of the RIV.
