Abstract: Aspects are provided which allow a UE configured with PUCCH repetitions to determine, in response to an indication from a base station to switch carriers for PUCCH repetitions, which CCs of a PUCCH group are configured for PUCCH repetitions, when CCs are configured for PUCCH repetitions, what resources in CCs are configured for PUCCH repetitions, and/or how to count PUCCH repetitions in configured CCs. For instance, the UE may receive a RRC-configured time pattern from a base station for switching between CCs of a PUCCH group for PUCCH transmissions, determine a time pattern of the CCs for the PUCCH transmissions from the RRC-configured time pattern, and transmit the PUCCH transmissions in the CCs according to the time pattern. The UE may also determine a subset of the CCs for the PUCCH transmissions, a resource allocation for each of the PUCCH transmissions, or a count for each of the PUCCH transmissions.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication by a user equipment, comprising receiving a first configuration indicating a scheduled time at which a signal is to be communicated between the apparatus and a network entity, the scheduled time being within a time interval associated with a first network energy state of the network entity. The implementations further include receiving a second configuration mapping the signal with a second network energy state of the network entity. The implementations further include receiving or transmitting the signal at the scheduled time while the network entity is in the second network energy state based on the second configuration.

Abstract: RACH occasion repetition and PRACH format selection in an NTN are disclosed. The base station may determine, based on at least one beam, a first PRACH configuration for at least one first UE and a second PRACH configuration for at least one second UE. The base station may transmit, to at least one of the at least one first UE or the at least one second UE, an indication of the first PRACH configuration and the second PRACH configuration. The UE, based on whether it is a first UE or a second UE, may select, based on the received indication, the first PRACH configuration or the second PRACH configuration for at least one beam. The UE may initiate, via the at least one beam, a RACH procedure for the selected first PRACH configuration or the selected second PRACH configuration.
