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 table0Table 1 is a default PDSCH resource allocation table for a normal Cyclic Prefix (CP), as shown in table 1, indicating the above-mentioned resource allocation information.
Figure BDA0001943360910000011
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 BDA0001943360910000021
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 BDA0001943360910000022
A similar scheduling approach is also used for the uplink.
Based on the existing standard implementation, for the case that the subcarrier spacing of PDCCH is smaller than that of PDSCH, the number of scheduled slots is more than that of the slots for transmitting scheduling DCI, so it is desired to schedule each slot on CC with large subcarrier spacing,meaning that more DCI needs to be transmitted. Taking the example shown in fig. 1, if it is desired to schedule slots 5 and 6 on CC2 and transmit scheduling information on 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 one
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 values of the subcarrier spacing of (a) are discussed separately. Suppose the following is according to the scheduling carrier CC1And scheduled carrier CC2The values of the subcarrier spacing of (a) are discussed separately. SCS1SCS, SCS representing CC1 scheduling carrier2SCS, which indicates the scheduled carrier of CC2, may be given as F ═ SCS2/SCS1。

a sub-index value i is determined based on K, i.e., K modulo F. 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. In practical applications, K may correspond to K representing PDCCH and PDSCH slot offsets0Value or K representing PDCCH to PUSCH slot offset2The value is obtained.
Following according to the scheduling carrier CC1And scheduled carrier CC2The values of the subcarrier spacing of (a) are discussed separately.

As shown in fig. 3, in the case where the subcarrier spacing of the scheduled carrier is 2 times the subcarrier spacing of the scheduled carrier, for example, the scheduled CC1 is 15KHz and the subcarrier spacing of the scheduled CC2 is 30 KHz.
In this case, according to the existing scheme, in order to implement scheduling for CC2, the UE needs to monitor two DCI at CC1 all the time to determine that it is single-timeScheduling of slots, or both slots are scheduled, table 2 is u2/u1The existing scheme implements different scheduling states when 2.

According to the method for resource allocation provided in this embodiment, for a plurality of time slots on the scheduled carrier within the time range corresponding to one time slot of the scheduled carrier, the UE only needs to monitor one DCI for one monitor, and according to K0The value determines the scheduling time slot range, and the combination condition of the scheduling time slots can be determined by combining the sub-index value i determined by the 1 bit of the scheduling index value M and the time slot offset K value, the following behavior example, the scheduling state and M and K0The relationship of values is shown in table 3.

2、F＝SCS2/SCS1＝4
As shown in fig. 4, in the case that the subcarrier spacing of the scheduled carrier is 4 times of the subcarrier spacing of the scheduling carrier, in order to schedule 4 slots corresponding to one slot of CC1, according to the existing scheme, 4 DCIs need to be detected, so as to implement scheduling for any 1, or 2, or 3, or 4 slots.
In the method for resource allocation provided in this embodiment, there are 15 states shown in table 4 for scheduling using one DCI. Each scheduling state herein corresponds to a slot combination state that determines the number of slots that an assigned slot contains and the position in the plurality of slots that can be combined. And the base station carries out scheduling of the uplink and downlink traffic channels in the time slots determined by the time slot combination states. Since F is 4, at most 4 timeslots can be contained in one timeslot combination status, and the timeslot combination status indicates how many of the 4 timeslots are allocated and which timeslots are allocated, and further determines the location of the specific allocated timeslot according to the absolute value of K0, which is usually indicated by the timeslot number. Similar for the other embodiments corresponding to F values.

If each state is indicated, 4 bits are needed, and all the indications can be realized by adopting the method for resource allocation provided by the embodiment with only 2 bits. SCS (F ═ SCS)2/SCS1The scheduling status indication when 4 is shown in table 5.

TABLE 5
The determination step is here performed by a time slot offset value K0The examples are as follows:
based on the value of K0, a range of time slots in which the scheduled time slots are located may be determined, and a combined status of the scheduled time slots may be further determined based on the value of M and the value of K0.
Assuming that the time slot for transmitting the PDCCH is n, the determined scheduled time slot is within the range defined by equation (2),
Figure BDA0001943360910000103
based on K0Determining a sub-index value i, where i ═ mod (K)0F) that is to say K0And F is subjected to modulus taking. And determining the combination state of the time slots scheduled in the scheduled time slot range according to the scheduling state indication table 4 by combining the values of the M and the i.
As shown in fig. 4, taking the base station as an example, the base station wants to schedule slots 12,13,control channel is transmitted on time slot 1 of carrier 1, then K0Range of values of (a) from 8 to 11. The corresponding scheduling status is 4, i.e. the first two time slots are scheduled simultaneously, as obtained from table 4. In table 5, i is 0 and M is 1. Thus K0＝8；
UE is based on K0First, 8, it is determined that the scheduled time slots range from (1+8/4) × 4 to (1+8/4) × 4+3, i.e., 12 to 15. Will K0Taking the modulus of 4 to obtain i as 0, looking up table 4 to obtain the scheduling status of 4 in combination with the value of M, corresponding to the first 2 slots, i.e. slots 12 and 13, in the scheduling slots 12-15 in fig. 4.
For example, M ═ 0, K0If the value is 5, i is 1, so that in combination with table 5, firstly, the corresponding time slot range is determined to be 8-11; m-0, i-1 indicates that state 1 is scheduled, as shown in fig. 5. M is 1, K0When the corresponding time slot range is determined to be 12-15, and when i is 0, the table 4 is looked up to obtain the state 4 indicating the schedule, as shown in fig. 6.
3、F＝SCS2/SCS1＝8
For the case that the subcarrier spacing of the scheduled carrier is 8 times of the subcarrier spacing of the scheduling carrier, 255 scheduling states as shown in table 6 are needed to realize the scheduling of all the time slots and combinations.

In the prior art, if each state is indicated, 8 bits are required, but all the indications can be realized by adopting the resource allocation method provided by the embodiment with only 5 bits, so that the overhead of the control channel indication is saved. SCS (F ═ SCS)2/SCS1The scheduling status indication when 8 is shown in table 7.
