    摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support channel state information (CSI) operations, such as CSI reporting. A UE may identify a change in CSI pertaining to communications with a base station or any other change in communications with a base station. The UE may transmit, to the base station and based on the change in CSI, a CSI scheduling request, which may include an indication to activate or grant resources for a CSI report transmission from the UE to the base station. The UE may receive, from the base station, a CSI report trigger based on the CSI scheduling request, and transmit, in response to receipt of the CSI report trigger, a CSI report over a physical layer uplink channel (e.g., a physical uplink shared channel (PUSCH)).

    摘要： This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for frame based operation and medium contention procedures in wireless networks. In some aspects, devices of a wireless network may perform receiver side contention operations. To illustrate, reference signals from a receiving device may be transmitted to a transmitting device and used by the transmitting device to estimate interference for transmitter side transmissions. Such receiver side reference signals may more accurately reflect the interference profile that transmissions sent by the transmitting device will face, such as when operating in a spectrum shared with many devices. The transmitting device may utilize the beam(s) that satisfy interference criteria when receiving the reference signals to transmit data. Receiver side frame based operation may provide a more stable interference profile which enables better rate prediction, and the better rate prediction may increase reliability and overall network and medium throughput.

    摘要： Wireless communications systems and methods related to performing contention credit-based listen-before-talk (LBT) for communications over a shared radio frequency band (e.g., in a shared spectrum or in an unlicensed spectrum) are provided. A wireless communication device performs a first clear channel assessment (CCA) including a first countdown. The wireless communication device transmits, after a gap period from the first countdown, a first communication signal. The wireless communication device performs a second CCA including a second countdown. The wireless communication device transmits, beginning before an end of the second countdown, a second communication signal based on at least a first contention credit associated with the gap period.
