Abstract: Methods, systems, and devices for wireless communications are described that support various configurations that enable repetitions of physical downlink shared channel (PDSCH) transmission according to a semi-persistent scheduling (SPS) configuration. A user equipment (UE) may receive downlink control information (DCI) associated with a PDSCH configuration and an SPS configuration. The UE may determine a number of PDSCH repetitions for a PDSCH transmission (e.g., an SPS PDSCH transmission) based on a rule associated with a priority between time domain resource allocation (TDRA) entries and configured repetition factors in an SPS configuration or a PDSCH configuration. The repetition number may be included in the TDRA entry, and the UE may receive a number of PDSCH repetitions based on a value of the PDSCH repetition number, or one instance of PDSCH may be received in each SPS period.

Abstract: A wireless station (STA) in a wireless local area network (WLAN) performs a method to avoid media access control (MAC) padding of a physical layer convergence protocol data unit (PPDU) (e.g., a trigger-based (TB) PPDU, etc.). The method can reduce current or power consumption by the STA, which can in turn optimize the STA and, in certain instances, the WLAN as whole. In one example, the method includes the STA receiving a trigger frame from an access point (AP). The trigger frame specifies a length of a PPDU. The method further includes the STA generating a TB PPDU based on the specifications in the trigger frame. In particular, the STA generates a PPDU that has a length that is less than the length specified by the trigger frame. The method also includes the STA transmitting the generated PPDU to the AP.

Abstract: Use of high frequency waves, such a millimeter waves, in many circumstances is prevented due to their inability to diffract around common obstacles. Disclosed herein is a system and method for transforming an incident high frequency wave. The system includes meta-atom pairs that define a surface. The meta-atom pairs generate an electro-magnetic response by interacting with an incident wave. This electro-magnetic response can be modulated by applying voltage to the meta-atom pairs. The electro-magnetic response transforms the incident wave into an emitted wave based on its controlled properties. The system and method are able to, by changing the voltage applied, steer the emitted wave a full 360 degrees as wells as transmit it through the surface without significant power loss. Embodiments enable the transmission through or around many obstacles that would normally interfere with high frequency waves.

The adjustment allows a transmission within the first sub-band and a reception within a second sub-band of the plurality of sub-bands to occur simultaneously at the mobile base station.
