Wherein, the first candidate resource set is one of the K1 candidate resource sets, the resource group occupied by the first candidate resource set belongs to the first resource pool, and the first identifier is used to identify the A first resource pool, in the K1 candidate resource sets, a resource group occupied by a candidate resource set belongs to a resource pool other than the first resource pool, and the first identifier is a non-negative integer; the K1 The candidate resource sets are indexed sequentially, the index of the first candidate resource set in the K1 candidate resource sets is the first index, and the first identifier and the target information are both used to determine the A first index, where the first index is used to determine the time-frequency positions of a positive integer number of resource groups occupied by the first candidate resource set; the K1 is a positive integer greater than 1.
The method in the second node according to claim 22, wherein the second candidate resource set is a candidate resource out of the K1 candidate resource sets and outside the first candidate resource set Set; the first candidate resource set and the second candidate resource set both occupy the same number of resource groups, and the resource group occupied by the second candidate resource set belongs to the first resource pool; the The index of the second candidate resource set in the K1 candidate resource sets is the second index, and the target information is used to determine whether the first index and the second index are continuous.
The method in the second node according to claim 23, wherein when the target information indicates that the first index and the second index are non-contiguous, the K1 candidate resource sets include K2 The first-type candidate resource set, the K2 first-type candidate resource sets occupy the same number of resource groups, and the first candidate resource set and the second candidate resource set belong to the K2 A first-type candidate resource set, where K2 is a positive integer greater than 1, the K2 indexes corresponding to the K2 first-type candidate resource sets are continuous, and the K2 first-type candidate resources The set is sequentially mapped to M1 candidate resource pools, the M1 candidate resource pools including the first resource pool; the M1 is a positive integer greater than 1, the M1 is equal to the K2, or the K2 is a positive integer multiple of M1.
The method in the second node according to claim 23, wherein when the target information indicates that the first index and the second index are consecutive, the K1 candidate resource sets include K3 The first-type candidate resource set, the K3 first-type candidate resource sets occupy the same number of resource groups, and the first candidate resource set and the second candidate resource set belong to the K3 The first-type candidate resource set, where K3 is a positive integer greater than 1, the K3 indexes corresponding to the K3 first-type candidate resource sets are continuous, and the K3 first-type candidate resources The set includes at least two first-type candidate resource sets corresponding to consecutive indexes and is mapped to a given resource pool.
The method in the second node according to any one of claims 22 to 25, wherein the first index of the sentence is used to determine the number of positive integers occupied by the first candidate resource set The time-frequency position of a resource group means: the first candidate resource set occupies Q1 resource groups, where Q1 is a positive integer, and the candidate resource pool group includes M1 candidate resource pools, where M1 is greater than 1. A positive integer, the M1 candidate resource pools include a total of Q2 resource groups, and the Q2 is a positive integer greater than Q1; the first index is used to determine the Q1 resources from the Q2 resource groups The position of the group; the M1 candidate resource pools include the first resource pool.
The method in the second node according to claim 26, wherein a positive integer number of resource groups occupied by any candidate resource set in the K1 candidate resource sets belong to the M1 candidate resource pools The Q2 resource groups included; the target information is used to indicate whether the detection order of the K1 candidate resource sets is the first order or the second order; the first order refers to the first node The K1 candidate resource sets are detected in the order of the first aggregation level and the second in the candidate resource pool; the second order means that the first node is ranked first in the candidate resource pool and the second in the aggregation level. The detection sequence detects the K1 candidate resource sets.
The method in the second node according to any one of claims 22-27, characterized in that it comprises:

Execute the first signal;

Wherein, the first signaling is used to indicate the third time-frequency resource set; the execution is sending, or the execution is receiving.
