CPC H04W 72/0453 (2013.01) [H04L 5/001 (2013.01); H04W 72/0446 (2013.01); H04W 16/14 (2013.01)] | 18 Claims |
1. A first node for wireless communications, comprising:
a first receiver, receiving first information, the first information being used for determining a target carrier;
a second receiver, detecting a first signaling in a first candidate resource set; and
a first transceiver, when the first signaling is detected, operating a first signal in a first carrier, and the first signaling being used for determining time-frequency resources occupied by the first signal in the first carrier;
wherein the operating action is receiving, or, the operating action is transmitting; the first signaling carries a first identifier, and the first identifier is used for identifying the first carrier; the first candidate resource set comprises a positive integer number of candidate resource group(s), and the first signaling occupies a candidate resource group in the first candidate resource set; any candidate resource group in the first candidate resource set belongs to a target time-frequency-resource pool, and the target time-frequency-resource pool comprises time-frequency resources other than a candidate resource group comprised in the first candidate resource set; frequency-domain resources occupied by the target time-frequency-resource pool belong to the target carrier; a target identifier is a non-negative integer, which is used for determining the first candidate resource set out of the target time-frequency-resource pool; the target time-frequency-resource pool is one of a first time-frequency-resource pool or a second time-frequency-resource pool; whether the target time-frequency-resource pool is the same as the first time-frequency-resource pool is used for determining the target identifier out of a first integer and a second integer; the first integer is not equal to the second integer, and the first integer and the second integer are both non-negative integers; the target time-frequency-resource pool is a Control Resource Set (CORESET); the first time-frequency-resource pool is a CORESET; the second time-frequency-resource pool is a CORESET; a physical layer channel carrying the first signaling is a PDCCH; the first signaling is a DL Grant and the operating action is receiving, or the first signaling is a UL Grant, and the operating action is transmitting.
