Abstract: According to various embodiments, a method performed by a user equipment (UE) in a wireless communication system, comprising: receiving, from a base station, a channel state information (CSI)-reference signal (RS) during an observation window (OW); predicting at least one first type CSI report during the OW; transmitting, to the base station, the at least one predicted first type CSI report during the OW and a second type CSI report at an end of the OW based on the received CSI-RS. The linear prediction based method is used for CSI-feedback in the wireless communication network, in situations where high/medium velocity feedback (i.e., Doppler) is present. The method can be used to enable a CSI-Type 2 codebook feedback feature during a mobility scenario.

Abstract: The disclosure relates to a pre-5G or 5G communication system to be provided for supporting higher data rates beyond a 4G communication system, such as LTE. A method includes receiving, in a first search space and a second search space that are linked for PDCCH repetition, at least one PDCCH including DCI; and receiving a PDSCH scheduled by the DCI based on QCL information of a CORESET with a lower ID among a first CORESET associated with the first search space and a second CORESET associated with the second search space, in case that the DCI does not include a TCI field and a time offset between a reception of the DCI and the PDSCH is greater than or equal to a threshold.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods for managing CSI feedback compression in wireless network by base station. The method includes transmitting at least one pilot symbol over first window. The method includes receiving at least one of a first and second type feedback from a UE at an end of the first window or after the first window. The method includes receiving the compressed CSI feedback based on predefined precoder weights in the first window. The method includes computing and predicting at least one precoder weight for the UE in at least one time instant in a second window for at least one sub-band of the UE based on the at least one of the first and second type feedback. The method includes managing the received CSI feedback compression based on the predicted precoder weight.

Abstract: The disclosure relates to a pre-5G or 5G communication system to be provided for supporting higher data rates beyond a 4G communication system, such as LTE. A method includes receiving, by a UE, PDCCH information from a network entity, where the PDCCH information includes DCI and PDSCH information, and determining, by the UE, the default beam behavior based on a CORESET with a lowest ID among first and second CORESETs, in response to determining that a TCI state is not present in the DCI and the scheduling offset between reception of all transmission occasions of DL DCI and the corresponding PDSCH information of the serving cell is greater than or equal to the threshold.
