Problems solved by technology

For the terminal, it needs to detect two control channels, which means greater power consumption; on the other hand, for the network, sending two control channels means greater overhead and greater control channel blocking probability

Embodiment 1

[0096] 1. Application Scenarios of Carrier Aggregation

[0097] The determined time slots 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.

[0098] The following is based on the scheduling carrier CC 1 and the scheduled carrier CC 2 The value of the subcarrier spacing of , is discussed separately. Assume the following according to the scheduling carrier CC 1 and the scheduled carrier CC 2 The value of the subcarrier spacing of , is discussed separately. SCS 1 Indicates the SCS of the CC1 scheduling carrier, SCS 2 Indicates the SCS of the carrier to be scheduled by CC2, you can set F=SCS 2 / SCS 1 .

[0099] Based on the time slot offset value K, the time slot range of the scheduled time slot can be determined, and bas...

Embodiment 2

[0144] 2. Application scenarios of single-carrier scheduling or self-carrier scheduling

[0145] In this case, the number P of time slots scheduled using the same DCI is configured through the network, and the time slots that may be scheduled at the same time are determined based on the value of P. The time slot scheduling situation in the same control information DCI is determined by combining the time slot offset value with the N-bit control information.

[0146] Total 2 P - 1 status requires indication, requires bits in combination with the slot offset value to indicate all states. For example, if the maximum number of concurrently scheduled time slots is configured as P=4, it can be stipulated that the time slots determined by the following formula are allowed to be scheduled by the same DCI:

[0147]

[0148] Firstly, based on the time slot offset value K, the time slot range of the scheduled time slot can be determined, and based on the M value and the time slot o...

Abstract

The invention discloses a resource allocation method and device and a computer readable storage medium, the method comprising: sending control information, with the control information comprising an N-bit information domain, N being a positive integer, information carried by the N-bit information domain being used for indicating a time slot combination state allocated by a terminal in combinationwith time domain resource allocation information; wherein the distributed time slot combination state comprises one or more time slots, or the number and positions of the time slots.

Description

technical field [0001] The present invention relates to communication technology, in particular to a resource allocation method, device and computer-readable storage medium. Background technique [0002] In NR (new radio), carrier aggregation between carriers of different numerology is supported, and cross-carrier scheduling is also supported. When scheduling uplink and downlink traffic channel transmission through DCI, the time domain resource assignment field (time domain resource assignment) in DCI provides an index value, and the time slot offset value K can be determined by combining the index value with the resource allocation table 0 , the scheduled SLIV value (Start and length indicator value), or directly indicate the start symbol S, the allocation length L, and the PDSCH / PUSCH mapping type. Table 1 is a default PDSCH resource allocation table for a conventional cyclic prefix (Cyclic Prefix, CP). As shown in Table 1, it indicates the above resource allocation infor...
