Description

Resource allocation indicating method, resource allocation obtaining method, base station and user terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource allocation indicating method, a resource allocation obtaining method, a base station, and a user terminal.

Background

With the development of mobile communication service demand, various organizations such as International Telecommunication Union (ITU) have started to research New wireless communication systems (i.e., 5G NR, 5Generation New RAT).

Currently, two frequency domain resource allocation types are supported in NR, which are respectively referred to as resource allocation type 0 and resource allocation type 1. The Resource allocation type 1 divides a bandwidth Part (Band Width Part, BWP) into N by Resource Block Group (RGB) as a unit_RBGThe Resource allocation granularity of the RBG, Resource allocation type 1, is one Resource Block (RB).

In some scenarios of NR, for example, in a BWP handover scenario and a scenario in which a common search space within the BWP is activated, the size of Downlink Control Information (DCI) is determined according to the size of the initial BWP, but not according to the size of the activated BWP, so that the number of bits for frequency domain resource allocation is likely to be smaller than the number of bits actually required. Generally, the number of bits for resource allocation type 1 is log₂N (N +1)/2, where N is the size of BWP, so that when the number of bits used for frequency domain resource allocation is smaller than the number of bits actually needed, the processing can be performed by using only part of the bandwidth in BWP, but this will result in that the entire bandwidth of BWP cannot be used, and thus the resource utilization rate is low.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, a flowchart of a resource allocation indication method according to an embodiment of the present invention is shown. As shown in fig. 1, the method is applied to a base station, and includes the following steps:

step 101, determining frequency domain resource allocation granularity; wherein the frequency domain resource allocation granularity is greater than one RB.

The frequency domain resource allocation granularity may be M consecutive RBs, where M is greater than 1. In particular, M may be 8, 16 or other values, which are not listed here.

Step 102, dividing the BandWidth Part (BWP) according to the BWP size and BWP allocation granularity to obtain N units.

Wherein the size of BWP is the number of RBs contained within BWP. The base station may divide the RBs in the BWP to obtain N units each including several RBs, and the units divided by the base station may also be referred to as RB units.

It should be noted that, in step 102, by dividing the BWP, all RBs in the BWP may be divided into corresponding cells, or only part of RBs in the BWP may be divided into corresponding cells.

Step 103, sending scheduling information to the user terminal; the scheduling information includes a frequency domain resource allocation indication field, and the frequency domain resource allocation indication field is used for indicating a unit allocated to the user terminal in the N units.

The scheduling Information related in step 103 may be Downlink Control Information (DCI) or may also be uplink scheduling Information carried in a Random Access Response (RAR); the frequency domain resource allocation indication field involved in step 103 may be a frequency domain resource allocation indication field of a specific frequency domain resource allocation type. Specifically, the specific frequency domain resource allocation type may be resource allocation type 1 of two frequency domain resource allocation types supported in NR.

After the base station sends the scheduling information to the user terminal, the user terminal receives the scheduling information from the base station. The user terminal may determine the unit allocated to itself by the user terminal according to the frequency domain resource allocation indication field in the received scheduling information. Thereafter, the user terminal can perform data transmission and reception on the RBs in the unit allocated to itself by the base station.

Optionally, determining the frequency domain resource allocation granularity includes:

and determining the frequency domain resource allocation granularity according to the bit number used for the frequency domain resource allocation indication field in the scheduling information and the BWP size.

In this embodiment, the base station may obtain the number of bits used in the frequency domain resource allocation indication field in the scheduling information and the size of the BWP, so as to determine the frequency domain resource allocation granularity more conveniently according to the obtained number of bits and the size of the BWP.

Thereafter, the base station can directly sum B with B

Substituted into any one of the two formulas provided in the present embodiment. Therefore, the base station can very conveniently determine the minimum positive integer M which meets the formula, namely the frequency domain resource allocation granularity.

It should be noted that, since M is the smallest positive integer satisfying the above formula, the value of M is the minimum value that does not exceed the number of bits of the frequency domain resource allocation indication field, that is, the granularity of the grain allocation is small, and accordingly, the flexibility of resource allocation can be better ensured.

Optionally, dividing the BWP according to the size of the BWP and the frequency resource allocation granularity to obtain N units, including:

The result of dividing by M is rounded up to obtain N;

Wherein the base station can utilize a formula

Obtaining N. After obtaining N, the base station may allocate the granularity M according to the frequency domain resources in the order from low to high within the BWP, and divide the BWP into N units. Specifically, the base station may divide each consecutive M RBs into one cell starting from the first RB in BWP, so that the first N-1 cells each include M RBs, and the nth cell (i.e., the last cell) may include M RBs or less than M RBs.

It can be seen that, in the present embodiment, the BWP size is varied

And the frequency domain resource allocation granularity M, the base station can very conveniently divide BWP into N units to achieve continuous resource allocation in case that the frequency domain resource allocation granularity M is greater than one RB.

wherein, the starting point of the first unit in the N units is the first RB in the BWP, and each unit in the N units comprises M RBs; or, the starting point of the first unit in the N units is the first RB in the BWP, the first N-1 units in the N units comprise M RBs, and the last unit in the N units comprises the rest RBs except the RBs comprised by the first N-1 units in the BWP.

Wherein the base station can utilize a formula

To obtainAnd N is added. After obtaining N, the base station may allocate the granularity M according to the frequency domain resources in the order from low to high within the BWP, and divide the BWP into N units.

Specifically, the base station may partition starting from the first RB in BWP and ensure that only M RBs are included in each cell. Thus, is at

In the case of integer multiple of M, all RBs in BWP are divided into corresponding cells; in that

In the case of not an integer multiple of M, the last few RBs in BWP are not divided into arbitrary units.

Of course, the base station may also divide starting from the first RB in BWP and divide every consecutive M RBs into one cell. For the last division, the number of remaining RBs may be M or greater, and the base station may divide all RBs remaining at this time into the last cell.

It can be seen that, in the present embodiment, the BWP size is varied

Then, the base station directly adds B and B

Substituting into the formula provided by this embodiment, the base station can determine M, that is, the frequency domain resource allocation granularity, conveniently.

Alternatively, M may be the smallest positive integer that satisfies the following formula and is a power of 2;

in particular, M may be 2, 4, 8, 16 or other powers of 2.

In this embodiment, M is the smallest positive integer which satisfies the above formula and is a power of 2, that is, M is the smallest positive integer which is a power of 2 and does not exceed the number of bits of the frequency domain resource allocation indication field, so that on one hand, the granularity of the particle allocation is small, the flexibility of the resource allocation can be ensured, and on the other hand, the alignment with the RBG boundary can be supported, thereby facilitating the multiplexing of the user terminals of different resource allocation types.

determining scheduling information including a frequency domain resource allocation indication domain; the frequency domain resource allocation indication field is used for indicating the starting unit and the number of units of the unit allocated to the user terminal in the N units.

Wherein, the starting unit and the number of units indicated by the frequency domain resource allocation indication field can be jointly coded.

In this embodiment, since the frequency domain resource allocation indication field is used to indicate the starting unit and the number of units of the unit allocated to the user terminal among the N units, the user terminal can very conveniently determine which units are specifically allocated to the user terminal among the N units according to the indication of the frequency domain resource allocation indication field.

It should be noted that the frequency domain resource allocation indication field may also be used to indicate each of the N units allocated to the ue, or to indicate the ending unit and the number of units in the N units allocated to the ue, which is also possible.

The following is a detailed illustration of specific implementations of embodiments of the present invention.

Currently, the Resource allocation type 1 divides a bandwidth Part (BWP) into N in Resource Block Group (RGB) units_RBGThe Resource allocation granularity of the RBG, Resource allocation type 1, is one Resource Block (RB).

Wherein，N_RBGThe pair can be obtained by the following formula:

wherein the content of the first and second substances,

is the size of the BWP, and,

the starting CRB of BWP is P, which is the RBG size determined according to the size of BWP and the configuration of the terminal by the base station. In general, the first RBG has a size of

If it is

The last RBG contains the number of RBs as

Otherwise, the number of RBs contained in the last RBG is P. The number of the other RBGs is P.

In particular, assuming RBG partitioning as shown in fig. 2,

when P is 2, then

The remaining RBGs were all 2 in size.

Note that the resource allocation type 1 supports only consecutive Virtual RBs (Virtual RBs), and indicates a start VRB number and a VRB number by joint coding, and the granularity of resource allocation is one RB. The number of bits for resource allocation type 1 is log₂N (N +1)/2, N is the size of BWP.

In a BWP handover scenario and a scenario in which a common search space within BWP is activated, if the number of bits used for frequency-domain resource allocation is smaller than the number of bits actually needed, simply increasing the granularity of resource allocation may make it difficult to perform frequency-domain multiplexing on UEs (user terminals) of different resource allocation types from the network side. For example, if the granularity of resource allocation type 1 is increased to 2 RBs (referred to as VRB sets in the following figures) shown in fig. 3, resource allocation type 1 can allocate any VRB sets in which any one VRB set starts to be continuous. It can be seen that the resource allocation at this time is always not aligned with the boundary of the RBG, thereby making it difficult for UEs of different resource allocation types to multiplex.

Similarly, if the resource allocation granularity and the RBG size are not related to each other as multiples, multiplexing difficulties may also be caused. For example, as shown in fig. 4 below, the assignment granularity is 3, and if an even number of VRB sets are assigned from an even number of VRB sets, it is not aligned with the RBG boundary; if an odd number of VRB sets are assigned starting from an odd number of VRB sets, they are also not aligned with the RBG boundary.

In view of this, embodiments of the present invention provide a method for performing continuous resource allocation when the frequency domain resource allocation granularity is greater than 1 RB, and some of the methods are described below by way of example.

The first embodiment is as follows:

assume that the number of bits of the frequency domain resource allocation indication field for resource allocation type 1 in DCI is 9, that is, B is 9. BWP size is 273 RBs, i.e

The frequency domain resource allocation granularity M is satisfied

M equals 9 when the integer is the smallest positive integer.

Next, the base station may divide the BWP into N RB units according to the frequency resource allocation granularity M in order from low to high frequency within the BWP, according to the formula

N is 31. Thus, when BWP is divided, RB Unit 0 (i.e., the first RB Unit)Meta) includes RB0 to RB 8; RB unit 1 (i.e., the second RB unit) includes RB9 through RB 17; by analogy, RB unit 29 (i.e., the third tenth RB unit) includes RB261 through RB 269; the RB unit 30 (i.e., the thirty-first RB unit, which may also be referred to as the last RB unit) includes RBs 270 to 272.

Assuming that the base station allocates RB units 29 and 30 to the user terminal, the frequency domain resource allocation indication field determined by the base station is used to indicate the starting 2 RB units (i.e., corresponding RBs 261 to 272) allocated to the user terminal for RB unit 29. After the user terminal receives the DCI carrying the frequency domain resource allocation indication field, the user terminal transmits and receives data on RBs 261 to 272 according to the indication of the frequency domain resource allocation indication field.

It can be seen that, in this embodiment, the base station can obtain M very conveniently, and divide BWP into N units to achieve continuous resource allocation in the case that the frequency domain resource allocation granularity M is greater than one RB. In addition, in this embodiment, the value of M is small, so that the flexibility of resource allocation can be ensured.

Example two:

The frequency domain resource allocation granularity M is satisfied

M equals 9 when the integer is the smallest positive integer.

Next, the base station may divide the BWP into N RB units according to the frequency resource allocation granularity M in order from low to high within the BWP. According to the formula

N may be 30.

In one case of dividing BWP, RB unit 0 (i.e., the first RB unit) includes RB0 through RB 8; RB Unit 1 (i.e., the second RB Unit) includes RB9 to RB 17; by analogy, RB unit 29 (i.e., the thirtieth RB unit, which may also be referred to as the last RB unit) includes RB261 through RB 269. It can be seen that, in this case

In the case of not being an integer multiple of M, the partial RBs in BWP may not be divided into RB units.

In another case of dividing BWP, RB unit 0 (i.e., the first RB unit) includes RB0 through RB 8; RB unit 1 (i.e., the second RB unit) includes RB9 through RB 17; by analogy, RB unit 29 (i.e., the thirtieth RB unit, which may also be referred to as the last RB unit) includes RBs 261 through 272. It can be seen that, in this case

In the case where M is not an integer multiple of M, more than M RBs may be included in the last RB unit.

For the above two cases, after BWP division is completed, assuming that the base station allocates RB unit 2 and RB unit 3 to the user terminal, the frequency domain resource allocation indication field determined by the base station is used to indicate the 2 RB units allocated to the user terminal starting for RB unit 2 (i.e., corresponding RB18 to RB 35). After receiving the DCI carrying the frequency domain resource allocation indication field, the user terminal transmits and receives data on RB18 to RB35 according to the indication of the frequency domain resource allocation indication field.

Example three:

The frequency domain resource allocation granularity M is satisfied

And is the smallest positive integer of power of 2, and M is 16.

Next, the base station may divide the BWP into N RB units according to the frequency resource allocation granularity M in order from low to high frequency within the BWP,

n ═ 18 units can be obtained. In this way, when BWP is divided, RB unit 0 (i.e., the first RB unit) includes the number of RBs of

I.e. from RB0 to RB 7; the RB unit 17 (i.e., the last RB unit) includes the RB number of

One, namely RB264 to RB 272; the other RB units each include 16 RBs.

Assuming that the base station allocates RB unit 0 and RB unit 1 to the user terminal, the frequency domain resource allocation indication field determined by the base station is used to indicate the 2 units allocated to the user terminal starting for RB unit 0 (i.e., corresponding to RB0 to RB 23). After receiving the DCI carrying the frequency domain resource allocation indication field, the user terminal transmits and receives data on RBs 0 to RB23 according to the indication of the frequency domain resource allocation indication field.

It can be seen that, in this embodiment, the base station can obtain M very conveniently, and divide BWP into N units to achieve continuous resource allocation in the case that the frequency domain resource allocation granularity M is greater than one RB. In addition, in this embodiment, M is the minimum positive integer that satisfies the above condition and is a power of 2, so that on one hand, the value of M is not too large, the flexibility of resource allocation can be ensured, and on the other hand, alignment with an RBG boundary can be supported, thereby facilitating multiplexing of user terminals of different resource allocation types.

Example four:

The frequency domain resource allocation granularity M is satisfied

And is the smallest positive integer of power of 2, and M is 16.

n ═ 16 units can be obtained. Thus, when dividing BWP, each RB unit includes 18 RBs, and the starting point of RB unit 0 (i.e., the first RB unit) is the second RB unit

RB, RB8, so RB unit 0 includes RB8 to RB 23; RB unit 1 (i.e., the second RB unit) comprises RB24 to RB 39; by analogy, RB unit 15 (i.e., the sixteenth RB unit, which may also be referred to as the last RB unit) includes RB248 to RB 263.

Assuming that the base station allocates RB unit 0 and RB unit 1 to the user terminal, the frequency domain resource allocation indication field determined by the base station is used to indicate the first 2 units (i.e., corresponding RBs 8 through RB36) allocated to the user terminal for RB unit 0. After receiving the DCI carrying the frequency domain resource allocation indication field, the user terminal transmits and receives data on RBs 8 to RB36 according to the indication of the frequency domain resource allocation indication field.

In conclusion, the embodiment of the invention can better ensure the resource utilization rate.
