Abstract

A method and a device in nodes used for wireless communications. A node receives a first information block; and monitors M1 control channel candidates in a first time window, and the M1 control channel candidates occupy M2 control channel elements; the first information block is used to indicate a scheduled cell set, and serving cells comprised by the scheduled cell set are divided into a first cell group and a second cell group; the scheduled cell set comprises a target cell, and K1 scheduling cells are capable of scheduling the target cell; a number of control resource pools of the K1 scheduling cells is used to determine a cell group to which the target cell belongs; a first quantitative value and a second quantitative value respectively correspond to the first cell group and the second cell group. The present disclosure ensures the flexibility of control signaling under multiple TRPs.

Dependent claims

A User Equipment (UE) for wireless communications, the UE comprising:

a receiver configured to:
receive signaling that indicates a scheduled cell set, wherein the scheduled cell set is divided into a first cell group and a second cell group, wherein the first cell group includes one or more serving cells, wherein a corresponding scheduling cell for each of the one or more serving cells in the first cell group has one or no Control Resource Set (CORESET) pool, and the second cell group includes one or more serving cells, wherein a corresponding scheduling cell for each of the one or more serving cells in the second cell group has at least two CORESET pools;
and
monitor a first plurality of control channel candidates in a time window, wherein:
the first plurality of control channel candidates occupy a second plurality control channel elements, the first plurality is less than or equal to a first threshold, the second plurality is less than or equal to a second threshold, the first threshold and the second threshold are determined based on a number the one or more serving cells in the first cell group, a number of the one or more serving cells in the second cell group, and a target factor, wherein the target factor is a number.
