Description

Resource allocation method, device and computer readable storage medium
Technical Field
The present invention relates to communications technologies, and in particular, to a method, an apparatus, and a computer-readable storage medium for resource allocation.
Background
In nr (new radio), carrier aggregation is performed between carriers supporting different numerologies, and cross-carrier scheduling is also supported. When the uplink and downlink traffic channel transmission is scheduled through the DCI, a time domain resource allocation (time domain resource allocation) in the DCI provides an index value, and the time slot offset value K can be determined by combining the index value with a resource allocation table0A Start and length indicator value for scheduling, or directly a starting symbol S and an allocation length L, and a PDSCH/PUSCH mapping type. Table 1 is a default PDSCH resource allocation table for a conventional Cyclic Prefix (CP), as shown in table 1, indicating the above-mentioned resource allocation information.
Figure BDA0002047783970000011
TABLE 1
Taking the scheduling resource allocation of the downlink PDSCH as an example, if the scheduled DCI is received in the time slot n, the allocated time slot for PDSCH transmission is:
Figure BDA0002047783970000021
K0is determined based on numerology of the scheduled PDSCH. Mu.sPDSCHAnd muPDCCHThe subcarrier spacing of the PDSCH and the subcarrier spacing of the PDCCH, respectively. Taking the scheduling case shown in fig. 1 as an example, the DCI scheduling information transmitted in slot 1 of slot CC1 is due to μPDSCH＝1，μPDCCHIf 0, the time slot of PDSCH is allocated
Figure BDA0002047783970000022
A similar scheduling approach is also used for the uplink.
Based on the existing standard implementation, for the case that the subcarrier spacing of the PDCCH is smaller than the subcarrier spacing of the PDSCH, the number of scheduled slots is greater than the number of slots for transmitting the scheduling DCI, and thus it is intended to schedule each slot on the CC with a large subcarrier spacing, which means that more DCI needs to be transmitted. Taking the example shown in fig. 1, it is desirable to schedule time slots 5,6 on CC2 ifTo transmit scheduling information in slot 1 on CC1, two DCIs are needed, each using K 02 slots can be scheduled 3 and 4. For the terminal, two control channels need to be detected, which means greater power consumption; on the other hand, for the network, two control channels are transmitted, which means larger overhead and larger control channel blocking probability.

Example two
Application scenario of carrier aggregation
The determined time slot may be scheduled according to the method for resource allocation provided in this embodiment. Specifically, scheduling of one or more time slots in cross-carrier scheduling may be achieved by combining N bits of control information in DCI with time domain resource allocation information.
Following according to the scheduling carrier CC1And scheduled carrier CC2The value conditions of the subcarrier intervals are discussed respectively:
hereinafter with SCS1Represents CC1SCS, SCS for scheduling carriers2Represents CC2SCS of scheduled carrier, which can make F ═ SCS2/SCS1。
Based on the slot offset value K (which may be K)0Or K2) A slot range in which the scheduled slot is located may be determined, and further, a combination status of the scheduled slot may be determined based on the M value of N bits and the slot offset value K.
Specifically, the determination method may be: the K value is converted into binary system and is divided into high H bit and low L bit. Wherein, L is log2F, the value of H depends on the value of K, when the time domain resource allocation table configured at the high level is determined, the digit of K is determined, for example, the maximum value of K in the time domain resource allocation table is K maxThe binary number determines the number of K bits, where the number of K bits can be expressed by the formula:
Figure BDA0002047783970000164
h is NK-L. For example, if F is 4, L is 2. When K ismaxWhen it is 11, the corresponding binary is a 4-bit binary ratioSpecial 1011, NKAnd 4, L is 2, and H is 2.
The bit value of the H bit determines the time slot range where the scheduled time slot is located, and the value is: and the offset value or the difference value between the time slot number of the scheduling carrier corresponding to the scheduled time slot and the time slot number of the sending scheduling DCI. Based on the offset value or the difference value, the time slot range of the scheduling carrier where the scheduled time slot is located can be determined, and the time slot range scheduled on the scheduling carrier can also be determined. Further, the N bits in combination with the L bits determine the combined status of the scheduled time slots within the range of time slots.
Taking fig. 5 as an example, from the perspective of the base station, the time slot to be scheduled is CC 212 and 13. Their corresponding scheduling carriers CC1The time slot above is 3, the sending time slot of the DCI is 1, and the difference is 2, which indicates that the high order value of the H bit is 10. Then, the value of L bit and the value of M of N bit are determined. Since slots 12 and 13 are scheduled, the corresponding scheduling state of table 4 is 4, which is represented by 0100 with 4 bits (a total of 15 states, which need to be represented by 4 bits).
In a specific implementation process, the order of the N bits and the low L bits of K may be adjusted, for example, N bits may be first followed by L bits. For example, if N bits are placed in front of L bits, 0100 corresponds to L bits 00, and N bits take the value of 01, i.e., K0To combine the H bit (10) and the L bit (00), the value is 8, and the corresponding N bit M value is 1, which has the same effect as the first embodiment.
If the way of first L bits and then N bits is adopted, 0100 corresponds to L bits of 01 and N bits of 00, namely K0To merge the H bit (10) and L bit (01), 1001, value 9, corresponding N bit M value 0;
correspondingly, when the UE side receives the K value and the N-bit M value, it will make a corresponding judgment to determine the combination status of the scheduled time slots within a certain time slot range. For example, assume that N bits are first and L bits are later to determine the slot combination status. Receiving M value of 1, K sent by the base station0(with K)0For example, K may be set2) The value was 8.
K0The 2-system of (2) is 1000, and since F is 4, L is 2 and H is 2. Height ofThe H bit is 10, and the slot range of the scheduling carrier where the scheduled slot is located is determined to be n +2(2 corresponds to 10). Corresponding to fig. 4, the scheduled timeslot is n-1, the scheduled timeslot is located in timeslot n + 2-3 on the scheduling carrier, and the corresponding timeslot range corresponding to the scheduled carrier is (n +2) × 4, (n +2) × 4+1, … …, (n +2) × 4+4-1, i.e. in the range of 12 to 15, which is equivalent to the formula (1) in the embodiment. But for a different expression.
The low L bits in combination with the N bits determine the combined status of the scheduled time slots within the range of scheduled time slots. In the case of F ═ 4, the slot combination status is 15 in table 4, and therefore, in combination with 4 bits of low K, L ═ 2 bits and N ═ 2 bits, the combination status of the slots scheduled in the scheduled slot range can be indicated and judged. When N bits are placed in front of L bits, K0When the value of N bit M is 01 corresponding to L bit 00, the corresponding state is 0100, the corresponding state is scheduling state 4, the first two slots are scheduled simultaneously within the corresponding 4 scheduling slot range, and the slot range determined by combining the high order of H bit is 12 to 15, which means that the scheduled time is slots 12 and 13.
In practical application, K may correspond to K indicating PDCCH and PDSCH slot offset0Value or K representing PDCCH to PUSCH slot offset2The value is obtained.
For the case of other F values, the principle is similar and not listed.
EXAMPLE III
Application scenario for situations of two-carrier scheduling or self-carrier scheduling
In this case, the number P of slots scheduled using the same DCI is configured by the network, and the slots that are likely to be scheduled at the same time are determined based on the value of P. And determining the time slot scheduling condition in the same DCI (control information) through the time slot offset value and the N-bit control information.
In total 2P-1 status required indication, need

A single bit in combination with a slot offset value indicates all states. For example, configuring the time slot scheduled at most simultaneously to be P ═ 4, it may be agreed toThe time slot determined by the following formula is allowed to be scheduled by the same DCI:
Figure BDA0002047783970000182
first, based on the slot offset value K, the slot range in which the scheduled slot is located may be determined, and further, based on the value M and the slot offset value K, the combination status of the scheduled slot may be determined.
Assuming that the time slot for transmitting the PDCCH is n, the determined scheduled time slot is located within the range defined by equation (3),
Figure BDA0002047783970000183
a sub-index value i is determined based on K, where i ═ mod (n + K, P), i.e., n + K modulo P. And determining the combined state of the time slots scheduled in the scheduled time slot range according to the scheduling state indication table by combining the value of M and the value of i.
The states that need to be indicated are the same as in table 2, and N-2 bits are needed to indicate all the states in conjunction with the value i determined by the slot offset value, which is the same as in table 3.
For example, in the case of self-carrier scheduling as shown in fig. 8, for example, if slot 9 is scheduled in slot 3, and corresponding to scheduling state 1, M is 0 and K is required0The value corresponds to the 2 nd of 8,9,10,11, i.e. K0It is desired to schedule time slots 12,13,14 simultaneously in time slot 6, corresponding to state 10, requiring M2, K 0The value is taken to be 3 rd of 12,13,14,15, namely K0＝8。
Similar to the second embodiment, the high H bits of K may be used to determine the scheduled time slot range, and the low L bits of K may be used in combination with N bits to determine the combination status of the scheduled time slots within the scheduled time slot range. The method is described in detail in example two.
Example four
The resource allocation method provided by the embodiment is suitable for a cross-carrier scheduling scenario, a single-carrier scheduling scenario or a self-carrier scheduling scenario. Note that K0/K2 here is similar to K above0/K2Are the same meaning.
In order to realize multi-slot scheduling, when the information of the PDSCH-timedomain resource allocation list or the PUSCH-timedomain resource allocation list is configured through a high layer, the value of k0/k2 in each PDSCH-timedomain resource allocation or PUSCH-timedomain resource allocation is configured as an integer value set.
Taking PDSCH as an example, k0 is an integer value of 0 to 32 in the existing standard, and the value is configured as a set of integer values as shown below. Thus, under the condition of not changing the existing DCI, the multi-slot scheduling can be realized. The specific content of the information element PDSCH-timedomainresource allocation list information element of the PDSCH time domain resource allocation table is as follows:

By combining the dynamic indication of the DCI, one PDSCH-timedomainresource allocation can be selected, which corresponds to one k0 set, thereby realizing scheduling of different time slot combinations of different time slots.
