Abstract: To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

Abstract: A method and apparatus of a device that handles time-varying packet size in the downlink. In some embodiments, the method performed by a user equipment (UE) comprises: receiving a first signaling comprising configuration of downlink (DL) Semi-Persistent Scheduling (SPS), wherein the DL SPS configuration comprises a periodicity of the DL SPS and a first indication for a first physical layer resource, and wherein the first physical layer resource is used to dynamically modify size of a second physical layer resource for SPS DL data transmission; receiving a second signaling that activates reception based on the DL SPS, wherein the second signaling comprises information to specify a boundary of the second physical layer resource; monitoring the first physical layer resource on each SPS occasion based on the periodicity to decode a second indication; determining the size of the second physical layer resource for SPS DL data transmission, based on the second indication; and receiving data on the second physical layer resource determined for each SPS occasion based on the determined size.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for utilizing a flexible slot indicator in wireless communication. A base station (BS) may establish communication with a first user equipment device (UE). The BS may determine a transmission direction for each of a plurality of symbols included in one or more slots. The BS may transmit a slot format indicator (SFI) to the UE. The SFI may indicate the transmission direction for each of the plurality of symbols included in one or more slots. The BS and the UE may perform communication during the one or more slots according to the determined transmission direction.

Abstract: Apparatuses, systems, and methods for performing multi-TRP transmissions using techniques for reducing wireless device power consumption. A wireless device may select a downlink signal buffering method for a communication slot. The downlink signal buffering method may be selected from a single antenna panel signal buffering method or a multi-antenna panel signal buffering method. One or more beams for which to perform downlink signal buffering for the communication slot may be selected based at least in part on the downlink signal buffering method selected. Downlink signals may be received from one or more cellular base stations during the communication slot using the selected one or more beams. The downlink signals received using the selected one or more beams may be buffered by the wireless device.

Abstract: A service device (e.g., a user equipment (UE), a new radio NR (gNB), or other network component) as a service provider/consumer can process or generate sidelink communications based on a downlink control information (DCI) for one or more sidelink configured grants that enables resource allocation for the sidelink communication. The device can determine whether to activate, release/deactivate, or request a retransmission for the one or more sidelink configured grants based on one or more fields of a DCI format 3_0 configuration of the DCI.
