Description

A method, apparatus and computer-readable storage medium for resource allocation

technical field

The present invention relates to communication technologies, and in particular, to a method, device and computer-readable storage medium for resource allocation.

Background technique

In NR (new radio), carrier aggregation between carriers of different numerologies is supported, and cross-carrier scheduling is also supported. When the uplink and downlink traffic channel transmission is scheduled through the DCI, the time domain resource assignment in the DCI provides an index value, and the time slot offset value K ₀ , the scheduling value can be determined through the index value combined with the resource allocation table. SLIV value (Start and length indicator value), or directly indicate the start symbol S and allocation length L, and the PDSCH/PUSCH mapping type. Table 1 is a default PDSCH resource allocation table for a regular cyclic prefix (Cyclic Prefix, CP). As shown in Table 1, the above-mentioned resource allocation information is indicated.

Table 1

K₀是基于被调度的PDSCH的numerology确定的。μ_PDSCH和μ_PDCCH分别是PDSCH的子载波间隔和PDCCH的子载波间隔。以图1所示调度情况为例，在时隙CC1的时隙1上发送的DCI调度信息，由于μ_PDSCH＝1，μ_PDCCH＝0，则分配的PDSCH的时隙为

对于上行也是类似的调度方式。Take the scheduling resource allocation of PDSCH below as an example, when the scheduled DCI is received in time slot n, the allocated time slot for PDSCH transmission is:

K ₀ is determined based on the numerology of the scheduled PDSCH. _μPDSCH and μPDCCH are the subcarrier spacing of PDSCH and the subcarrier spacing of _PDCCH , respectively. Taking the scheduling situation shown in FIG. 1 as an example, in the DCI scheduling information sent on time slot 1 of time slot CC1, since μ _PDSCH =1 and μ _PDCCH =0, the allocated PDSCH time slot is

A similar scheduling method is also used for the uplink.

Based on the existing standard implementation, for the case where the subcarrier spacing of PDCCH is smaller than that of PDSCH, and the number of scheduled time slots is more than the number of time slots for transmitting and scheduling DCI, then you want to schedule to a larger subcarrier spacing Each slot on the CC means that more DCI needs to be transmitted. Taking the example shown in Figure 1, if you want to schedule time slots 5 and 6 on CC2, if you want to transmit scheduling information in time slot 1 on CC1, two DCIs are required, and K ₀ =3 and 4 can be used respectively to convert 2 time slots for scheduling. For the terminal, the need to detect two control channels means greater power consumption; on the other hand, for the network, sending two control channels means greater overhead and greater control channel blocking probability.

The method for resource allocation provided by this embodiment is described in detail below with reference to specific application scenarios.

Example 1

1. Application Scenarios of Carrier Aggregation

The determined time slot may be scheduled according to the resource allocation method provided in this embodiment. Specifically, the scheduling of one or more time slots in the cross-carrier scheduling can be implemented by combining the N-bit control information in the DCI with the time-domain resource allocation information.

The following discussion is based on the values of the subcarrier intervals of the scheduling carrier CC ₁ and the scheduled carrier CC ₂ respectively. SCS ₁ represents the SCS of the carrier scheduled by CC ₁ , and SCS ₂ represents the SCS of the carrier scheduled by CC ₂ , and F=SCS ₂ /SCS ₁ can be set.

Based on the time slot offset value K, the time slot range in which the scheduled time slot is located may be determined, and based on the M value and the time slot offset value K, the combined state of the scheduled time slots is further determined.

Assuming that the time slot for sending PDCCH is n, the determined scheduled time slot is within the range defined by equation (1),

A sub-index value i, is determined based on K, that is, K modulo F. Combining the value of M and the value of i, the combined state of the time slots scheduled within the range of the scheduled time slots is determined according to the scheduling state indication table. In practical applications, K may correspond to the value of K ₀ representing the offset of the PDCCH and the PDSCH time slot or the value of K ₂ representing the offset of the time slot of the PDCCH and the PUSCH.

The following discussion is based on the values of the subcarrier intervals of the scheduling carrier CC ₁ and the scheduled carrier CC ₂ respectively.

1. F=SCS ₂ /SCS ₁ =2

As shown in FIG. 4 , when the subcarrier spacing of the scheduled carrier is twice the subcarrier spacing of the scheduled carrier, for example, the scheduled CC1 is 15KHz, and the scheduled _CC2 has _a subcarrier spacing of 30KHz.

In this case, according to the existing solution, in order to realize the scheduling of CC ₂ , the UE needs to monitor the two DCIs of the monitor in CC ₁ all the time to determine whether it is a single-slot scheduling or whether both time slots are used for scheduling. Scheduling, Table 2 shows that the existing solutions achieve different scheduling states when u ₂ /u ₁ =2.

Table 2

According to the method for resource allocation provided in this embodiment, for multiple time slots on the scheduled carrier within the time range corresponding to one time slot of the scheduling carrier, the UE only needs to monitor one DCI of the monitor, and determine the scheduled time slot according to the K ₀ value. The time slot range, combined with 1 bit of the scheduling index value M and the sub-index value i determined by the time slot offset K value, can determine the combination of the scheduled time slots. The following row is an example, the scheduling status and the values of M and K ₀ The relationship is shown in Table 3.

table 3

2. F=SCS ₂ /SCS ₁ =4

As shown in FIG. 5 , in the case where the subcarrier spacing of the scheduled carrier is 4 times the subcarrier spacing of the scheduling carrier, in order to schedule 4 time slots corresponding to one time slot of CC ₁ , according to the existing scheme, it is necessary to detect 4 DCIs, realize the scheduling of any 1, or 2, or 3, or 4 time slots.

In the method for resource allocation provided in this embodiment, in order to use one DCI scheduling, there are 15 states as shown in Table 4. Each scheduling state here corresponds to a time slot combination state, which determines the number of time slots included in the allocated time slot and the position in the multiple time slots that can be combined. The base station performs scheduling of uplink and downlink traffic channels in the time slots determined by the combined state of these time slots. Because F=4 at this time, a time slot combination state can contain up to 4 time slots, and the time slot combination state indicates how many of the 4 time slots are and which ones are allocated time slots, which is further combined with K ₀ The absolute value determines the location of the specific allocated time slot, which is usually represented by the number of the time slot. Similar for other F values in corresponding embodiments.

Table 4

If each state is indicated, 4 bits are required, while the resource allocation method provided in this embodiment only needs 2 bits to realize all indications. Table 5 shows the scheduling status indication when F=SCS ₂ /SCS ₁ =4.

table 5

Here, the determination steps are expressed as follows by taking the time slot offset value K ₀ as an example:

Based on the value of K ₀ , the time slot range in which the scheduled time slot is located can be determined, and the combined state of the scheduled time slot is further determined based on the value of M and the value of K ₀ .

Assuming that the time slot for sending PDCCH is n, the determined scheduled time slot is within the range limited by equation (2),

A sub-index value i is determined based on K ₀ , where i=mod(K ₀ , F), that is, taking K ₀ modulo F. Combined with the value of M and the value of i, the combined state of the time slots scheduled within the range of the scheduled time slots is determined according to the scheduling state indication table 4.

As shown in Figure 5, taking the base station as an example, the base station wants to schedule time slots 12 and 13 on CC ₂ , and the control channel is sent on time slot 1 of carrier 1, so the value range of K ₀ is 8 to 11. The corresponding scheduling state obtained from Table 4 is 4, that is, the first two time slots are scheduled at the same time. Look up Table 5, corresponding to i=0, M=1. Therefore, K ₀ =8; based on K ₀ =8, the UE first determines that the scheduled time slots range from (1+8/4)*4 to (1+8/4)*4+3, ie, 12 to 15. Taking K ₀ =8 modulo 4 to obtain i is 0, combined with the value of M, look up Table 4 to obtain the scheduling status as 4, which corresponds to the first 2 time slots in the scheduling time slots 12 to 15 in Figure 5, namely the time slot 12, 13.

For example, if M=0, and K ₀ is 5, then i=1. Therefore, in combination with Table 5, the corresponding time slot range is first determined to be 8 to 11; M=0, i=1 indicates that state 1 is scheduled. , as shown in Figure 5. M=1, K ₀ =8, first determine that the corresponding time slot range is 12-15, secondly i=0, look up table 4 to obtain that state 4 is scheduled, as shown in FIG. 7 .

3. F=SCS ₂ /SCS ₁ =8

For the case where the subcarrier spacing of the scheduled carrier is 8 times the subcarrier spacing of the scheduling carrier, to realize the scheduling of all time slots and combinations, 255 scheduling states as shown in Table 6 are required.

Table 6

In the prior art, if each state is indicated, 8 bits are required, while the resource allocation method provided in this embodiment only needs 5 bits to realize all indications, thus saving the overhead of control channel indication. Table 7 shows the scheduling status indication when F=SCS ₂ /SCS ₁ =8.

Table 7

It can be concluded from the above three situations: when the scheduled time slot and the time slot of the control information are located on different carriers, in the control information of N bits, the value of N satisfies:

其中；

in;

为向上取整运算。SCS ₂ is the subcarrier spacing of the traffic channel, SCS ₁ is the subcarrier spacing of the control channel,

is a round-up operation.

It should be noted that, in this embodiment, K ₀ can be replaced by K ₂ , that is, this solution is applicable to both downlink and uplink scheduling. In addition, the bits of the time slot offset and the N bits can also be combined, and different values can be used to represent the conditions of different scheduled time slots.

Embodiment 2

1. Application Scenarios of Carrier Aggregation

The determined time slot may be scheduled according to the resource allocation method provided in this embodiment. Specifically, the scheduling of one or more time slots in the cross-carrier scheduling can be implemented by combining the N-bit control information in the DCI with the time-domain resource allocation information.

The following discussion is based on the value of the subcarrier spacing of the scheduling carrier CC ₁ and the scheduled carrier CC ₂ respectively:

Hereinafter, SCS ₁ represents the SCS of the carrier scheduled by CC ₁ , and SCS ₂ represents the SCS of the carrier scheduled by CC ₂ , so that F=SCS ₂ /SCS ₁ .

Based on the time slot offset value K (which can be K ₀ or K ₂ ), the time slot range in which the scheduled time slot is located can be determined, and further, the scheduled time slot can be determined based on the M value of N bits and the time slot offset value K The combined state of the time slots.

H为N_K-L。以F＝4为例，则L＝2。当K_max＝11时，对应二进制为4位二进制比特1011，N_K＝4，则L＝2，H＝2。Specifically, the determination method may be: converting the K value into binary, and dividing it into high H bits and low L bits. Among them, the value of L is log ₂ F, and the value of H depends on the value of K. After the time-domain resource allocation table configured by the high-level is determined, the number of bits of K is determined. For example, the value of K in the time-domain resource allocation table is determined. The maximum value is K _max , then its binary digits determine the number of digits of K. Here, the number of digits of K can be expressed as:

H is NK- _L . Taking F=4 as an example, then L=2. When K _max =11, the corresponding binary is 4 binary bits 1011, N _K =4, then L=2, H=2.

The bit value of the H bit determines the time slot range in which the scheduled time slot is located, and its value is: the offset between the time slot number of the scheduling carrier corresponding to the scheduled time slot and the time slot number for sending the scheduled DCI value or difference. Based on the offset value or difference value, the time slot range of the scheduled carrier where the scheduled time slot is located may be determined, and the scheduled time slot range on the scheduled carrier may also be determined. Further, the N bits are combined with the L bits to determine the combined state of the scheduled time slots within the time slot range.

Taking FIG. 5 as an example, from the point of view of the base station, the time slots to be scheduled are 12 and 13 on CC ₂ . The time slot on their corresponding scheduling carrier CC ₁ is 3, the transmission time slot of the DCI is 1, and the difference is 2, indicating that the high-order value of the H bit is 10. After that, the value of the L bit and the value M of the N bit must be determined. Since time slots 12 and 13 are scheduled, the corresponding scheduling state in Table 4 is 4, which is represented by 0100 using 4 bits (there are 15 states in total, and 4 bits are required for representation).

In a specific implementation process, the sequence of the N bits and the lower L bits of K can be adjusted, for example, the N bits can be first followed by the L bits. For example, if N bits are placed in front of L bits, 0100 corresponds to L bit 00, and the value of N bit is 01, that is, K ₀ is the combination of H bit (10) and L bit (00), the value is 8, the corresponding N The value of the bit M is 1, and the effect is the same as that in the first embodiment.

If the method of L-bit first and then N-bit is adopted, then 0100 corresponds to L-bit 01, N-bit is 00, that is, K ₀ is the combination of H-bit (10) and L-bit (01), which is 1001, and the value is 9, corresponding to The N-bit M value of 0 is 0;

Correspondingly, from the perspective of the UE side connection, upon receiving the K value and the N-bit M value, it will also make corresponding judgments to determine the combined state of the scheduled time slots within a certain time slot range. For example, it is assumed that N bits are first and L bits are last to determine the slot combination state. The value of M received from the base station is 1, and the value of K ₀ (taking K ₀ as an example, it may also be K ₂ ) is 8.

The binary representation of K ₀ is 1000. Since F=4, L=2 and H=2. The high H bit is 10, which determines that the time slot range of the scheduling carrier where the scheduled time slot is located is n+2 (2 corresponds to 10). Corresponding to Fig. 4, the scheduled time slot is n=1, the scheduled time slot is located in the time slot n+2=3 on the scheduled carrier, and the corresponding time slot range of the scheduled carrier is (n+2)* 4, (n+2)*4+1, ..., (n+2)*4+4-1, that is, in the range of 12 to 15, is equivalent to formula (1) in the embodiment. Just a different way of expressing it.

The lower L bits in combination with the N bits determine the combined state of the time slots scheduled within the range of the scheduled time slots. In the case of F=4, the time slot combination states are 15 kinds in Table 4. Therefore, combining the low L=2 bits of K and N=2 bits, a total of 4 bits can indicate and judge that when scheduled The combined state of the time slots scheduled within the slot range. When N bits are placed in front of L bits, K ₀ =8, corresponding to L bit 00, and N bit M value is 01, then the corresponding state is 0100, which is scheduling state 4, corresponding to 4 scheduling time slots before simultaneous scheduling For the two time slots, the time slot range determined in combination with the high bit of the H bit is 12 to 15, indicating that time slots 12 and 13 are scheduled this time.

In practical applications, K may correspond to the value of K ₀ representing the offset of the PDCCH and the PDSCH time slot or the value of K ₂ representing the offset of the time slot of the PDCCH and the PUSCH.

For other F values, the principle is similar and will not be listed one by one.

2. Application scenarios of single-carrier scheduling or self-carrier scheduling

In this case, the number of timeslots P scheduled using the same DCI is configured by the network, and the timeslots that may be scheduled at the same time are determined based on the value of P. The time slot scheduling in the same control information DCI is determined by combining the time slot offset value with the N-bit control information.

个比特结合时隙偏移值指示所有状态。例如配置最多同时调度的时隙为P＝4，则可以约定以下公式确定的时隙是允许被同一个DCI调度的：There are a total of 2 ^P -1 states that need to be indicated, need

bits to indicate all states in combination with the slot offset value. For example, if the time slot that can be scheduled at most at the same time is configured as P=4, it can be agreed that the time slot determined by the following formula is allowed to be scheduled by the same DCI:

First, based on the time slot offset value K, the time slot range in which the scheduled time slot is located can be determined, and based on the M value and the time slot offset value K, the combined state of the scheduled time slot is further determined.

Assuming that the time slot for sending PDCCH is n, the determined scheduled time slot is within the range defined by equation (3),

A sub-index value i is determined based on K, where i=mod(n+K, P), that is, n+K modulo P. Combining the value of M and the value of i, the combined state of the time slots scheduled within the range of the scheduled time slots is determined according to the scheduling state indication table.

The states that need to be indicated are the same as those in Table 2, and all the states need to be indicated by N=2 bits combined with the i value determined by the time slot offset value, and the indicated states are the same as those in Table 3.

For example, in the case of self-carrier scheduling shown in Figure 8, for example, if you want to schedule time slot 9 in time slot 3, corresponding to scheduling state 1, you need M=0, and the value of K ₀ corresponds to 8, 9, 10, and 11. The second of , that is, K ₀ =6. If you want to schedule time slots 12, 13, and 14 in time slot 6 at the same time, corresponding to state 10, you need M = 2, and the value of K ₀ takes 12, 13, 14, and 15. The third one, namely K ₀ =8.

Similar to Embodiment 2, the high H bits of K may be used to determine the range of scheduled time slots, and the low L bits of K combined with N bits may be used to determine the combined state of the time slots scheduled within the range of scheduled time slots. The method is described in detail in the second embodiment.

Embodiment 4

The resource allocation method provided in this embodiment is applicable to a cross-carrier scheduling scenario, a single-carrier or self-carrier scheduling scenario. It should be noted that k0/k2 here has the same meaning as K ₀ /K ₂ above.

In order to implement multi-slot scheduling, the k0/k2 value in each PDSCH-TimeDomainResourceAllocation or PUSCH-TimeDomainResourceAllocation can be configured as an integer value set when the PDSCH-TimeDomainResourceAllocationList or PUSCH-TimeDomainResourceAllocationList information can be configured by the high layer.

Taking PDSCH as an example below, k0 is an integer value from 0 to 32 in the existing standard. As shown below, the value is configured as a set of integer values. In this way, multi-slot scheduling can be realized without changing the existing DCI. The specific content of the information element PDSCH-TimeDomainResourceAllocationList informationelement of the PDSCH time domain resource allocation table is as follows:

Figure 9 is a configuration example of the k0 set, in which the PDSCH-TimeDomainResourceAllocationList is 16 PDSCH-TimeDomainResourceAllocations, each of which corresponds to the 16 k0 value sets in Figure 9, respectively {0}, {0,1 }, {0,1,2}, {0,1,2,3}, {4}, {4,5}, {4,5,6}, {4,5,6,7}, {8 }, {8,9}, {8,9,10}, {8,9,10,11}. Combined with the dynamic indication of DCI, a PDSCH-TimeDomainResourceAllocation can be selected, corresponding to a k0 set, so as to realize the scheduling of different time slot combinations of different time slots.
