Methods for avoiding adverse effects caused by NES

A method performed by a network for activation of a Network Energy Saving, NES, operation, comprising:

• signaling, to one or more user equipments, UEs, an indication about activation of a NES operation at one or more cells;
• receiving, from at least one of the one or more UEs, UE feedback related to the one or more cells, wherein the UE feedback comprises a reconfiguration request or an exemption request that actively requests modification or omission of the NES operation, wherein the UE feedback is received within a pre-warning window during which UEs can request to not activate the NES operation, wherein UEs are allowed to provide the UE feedback until a certain time before a first activation time of the NES operation, and wherein UE feedback provided after said certain time is not considered by the network node;
• and
• modifying the NES operation based at least in part on the UE feedback.

A method performed by a network for activation of a Network Energy Saving, NES, operation, comprising:

• signaling, to one or more user equipments, UEs, an indication about activation of a NEW operation at one or more cells;
• receiving, from at least one of the one or more UEs, UE feedback related to the one or more cells;
• and
• modifying the NES operation based at least in part on the UE feedback,
• wherein the UE feedback comprises one or more of:
• information about lack of suitable targets for conditional handover;
• preferred configuration information related to one or more possible handover target cells;
• information about an expected duration of time during which one or more serving cells and/or target cells are not desired to operate in said NES operation;
• a request to not deactivate a serving cell of the UE;
• information about preferred cell discontinuous transmission or reception configuration;
• a preferred on-duration offset;
• a period;
• an off-duration duration;
• information about lack of suitable target candidate primary secondary cells, PSCells, for Conditional PSCell Change, CPC;
• preferred configuration in terms of NES operation related to a current PSCell and/or one or more target candidate PSCells;
• a preference to not configure or continue a NES operation on the current PSCell and/or one or more target candidate PSCells;
• information about an expected duration of time during which the current PSCell and/or one or more target candidate PSCells are not desired to operate in said NES operation;
• assistance request;
• a complaint;
• an exemption request, and
• wherein information about lack of suitable target candidate primary secondary cells, PSCells, of Conditional PSCell Change, CPC, is communicated between a master node, MN, and one or more secondary nodes, SNs, one or more source secondary nodes, S-SNs, and/or one or more target secondary nodes, T-SNs.
