Abstract: Aspects presented herein may enhance the determination of ED threshold to improve the channel access probability of the UE and the base station. In one aspect, a UE or a base station determines an ED threshold for a transmission, where the ED threshold is based on a characteristic of the transmission, a channel, or the UE/base station excluding a maximum transmit power of the UE or the base station. The UE or the base station determines whether an energy on the channel is less than the determined ED threshold. The UE or the base station transmits on the channel when the energy is determined to be less than the ED threshold.

Abstract: Methods, systems, and devices for wireless communications are described. An energy receiver may receive a first message that includes information indicative of a time division duplex (TDD) configuration for wireless energy and information transfer, the TDD configuration indicating a temporal arrangement of energy and information resources. In some examples, an energy transmitter may configure the TDD configuration as cell-specific, energy receiver-specific, or using a slot format indication (SFI). In addition, the TDD configuration may include flexible resources able to be used for energy or information transfer. The energy receiver may receive one or more energy signals during the energy resources in accordance with the TDD configuration, the one or more energy signals providing energy to the energy receiver. Accordingly, the energy receiver may transmit one or more information signals during the information resources in accordance with the TDD configuration.

Abstract: Methods, systems, and devices for wireless communications are described. Methods, systems, and devices for wireless communications are described. The described techniques provide for joint hybrid automatic repeat request (HARQ) feedback for sidelink transmissions and downlink transmissions. In some examples, a base station may transmit control signaling to a user equipment (UE) indicating a configuration for a joint HARQ codebook. The UE may receive a set of sidelink transmissions and a set of downlink transmissions, generate a joint HARQ codebook based on a downlink counter (e.g., a counter downlink assignment index) for the downlink transmissions and a sidelink counter (e.g., a counter sidelink assignment index) for the sidelink transmissions, where the downlink counter and the sidelink counter are jointly summed, and transmit feedback message to the base station for the downlink transmissions and the sidelink transmissions based on the joint HARQ codebook.
