A UE receives configuration for interference mitigation pattern(s) indicating which resource elements in a time-frequency resource space should be measured. The UE performs interference measurements based on the received one or more interference mitigation patterns. A network node determines configuration for interference mitigation pattern(s0 indicating which resource elements in a time-frequency resource space should be measured by a user equipment. The network node sends, toward the user equipment, the configuration for use by the user equipment to perform interference measurements of the one or more interference mitigation patterns.

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of energy harvesting information supported User Equipment (UE) scheduling. The method includes reporting, to a network device in the radio network, energy harvesting capability of the terminal device indicating a first energy value (ΔE) collected during a first time interval (Δt) and a second energy value (E) averaged over a second time interval; and communicating with the network device to transmit data according to scheduling information received from the network device and determined based on the energy harvesting capability of the terminal device. In this way, the terminal device may be scheduled by the network based on its energy harvesting capability, to maintain a trade-off between harvested energy utilization and fairness in scheduling from Passive IoT UEs.

This disclosure presents processes for improving the quality of NR PDCCH reception at a UE when transmitted in a same orthogonal frequency-division multiplexing (OFDM) symbol and a same frequency domain resource element as an LTE CRS. Using a capability parameter of the UE, a network node can transmit an LTE CRS and NR PDCCH in the same OFDM symbol and the same frequency domain resource elements using various encoding schemes. The encoding schemes can be one or more of puncture signalling, superposition signalling, relative power levels, UE type, adjusting the AL of the LTE CRS, or various combinations thereof. The UE can decode the PDDCH using the encoding scheme. Legacy UEs can be supported with this disclosure by the network node selecting supported UE capabilities for the encoding. The network node can balance transmission reliability with available resources.

A determination is made that a registration attempt by a UE with a cell of a wireless network has failed when the UE is in a current tracking area. The UE updates a first list with indications(s) corresponding to the cell and an indication of the current tracking area, and the UE uses the first list for additional registration attempts. A network node sends, toward the UE, a request for the UE to store information, the storing to be in response to registration attempts by the UE with cells of the wireless network having failed while in corresponding tracking areas. The information is to include indication(s) corresponding to the cells and corresponding indication(s) of the tracking areas for the cells. The network node receives, in response to a successful secure connection having been performed between the wireless network and the UE, the information from the user equipment.
