Abstract: Apparatuses and methods for waveform determination for uplink (UL) transmissions. A method includes receiving first information indicating whether transform precoding is enabled or disabled, second information indicating a presence of a transform precoder indication (TPI) field in a downlink control information (DCI) format, third information for a configuration related to a resource allocation associated with transmissions of physical uplink shared channels (PUSCHs) with transform precoding disabled, and a channel providing the DCI format that schedules a transmission of a PUSCH. The method further includes determining whether the transform precoding is enabled based on the TPI field, that the configuration is used when transform precoding is disabled, and that the configuration is not used when transform precoding is enabled.

Abstract: A user equipment (UE) in a wireless communication system includes a processor. The processor is configured to determine a channel bandwidth for a frequency band in which the wireless communication system operates, and when the channel bandwidth is 3 megahertz (MHz), determine a punctured bandwidth of a synchronization signals and physical broadcast channel (SS/PBCH) block as 144 subcarriers, wherein subcarriers 0 to 47 and subcarriers 192 to 239 are punctured from 240 subcarriers of the SS/PBCH block bandwidth, and all 4 symbols of the SS/PBCH block are punctured. The UE further includes a transceiver operably coupled to the processor. The transceiver is configured to receive the SS/PBCH block based on the punctured bandwidth of the SS/PBCH block.

Abstract: Apparatuses and methods for random access procedures with multiple transmission reception points or cells in a wireless communication system. A method for performing random access (RA) procedures by a user equipment includes receiving a first configuration for RA. The method further includes initiating a first RA procedure with a first transmission-reception point (TRP) based on the first configuration and initiating a second RA procedure with a second TRP prior to completion of the first RA procedure. A method for operating a base station includes transmitting a first configuration for RA corresponding to a first TRP and transmitting a second configuration for RA corresponding to a second TRP. The first TRP and the second TRP are associated with a same cell.

Abstract: Methods and apparatuses for resource association and link recovery for repeaters in a wireless communication system. A method for a network-controlled repeater (NCR) includes receiving first information for time-domain resources and for corresponding beams for an access link and receiving or transmitting radio frequency (RF) signals on the access link using the beams over the corresponding time-domain resources prior to a link failure event. The method further includes determining the link failure event on a control link (C-link) and performing a link recovery procedure on the C-link. The method further includes suspending receiving or transmitting the RF signals on the access link using the beams over the corresponding time-domain resources during the link recovery procedure.
