摘要： Aspects relate to the amount of shared bandwidth to be used for channel occupancy time (COT) sharing. An initiator device may use a clear channel assessment procedure to gain access to wireless communication resources for a COT that will be shared between the initiator device and a responder device. In some examples, the responder device may determine the shared bandwidth based on information that is implicit in a transmission from the initiator device. For example, the responder device may determine the shared bandwidth based at least in part on a bandwidth of a transmission from the initiator device.

摘要： A random access control method can be applied to electronic devices and include: determining, when a medium access control layer receives a beam failure instance indication sent by a physical layer, whether a count value of a beam failure indication counter is greater than or equal to a preset value; detecting, when the count value of the beam failure indication counter is greater than or equal to the preset value, whether the electronic device is currently performing a random access; triggering, when the electronic device is not currently performing the random access, a new random access. According to the embodiments of the present disclosure, the user device can be prevented from occupying resources for a contention free random access (CFRA) for a long time.

摘要： Aspects of the disclosure provide a method of beam failure handling. The method can include performing beam quality measurement of one or more beams transmitted from a base station (BS) at a user equipment (UE) in a beamformed wireless communication system, determining a beam failure occurs based on the beam quality measurement, and performing a beam recovery process that includes at least one of a contention-free beam recovery process or a contention-based beam recovery process. The one or more beams are used for transmitting physical downlink control channels (PDCCHs).

摘要： This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for one or more wireless devices to gain access to a wireless channel of a radio frequency spectrum band. In some aspects, a recurring coordinated medium interval is defined in the time domain and associated with the wireless channel. The coordinated medium interval includes a first time period, which may be referred to as a common reservation window, and a second time period, which may be referred to as a scheduled medium access window. During the first time period, access points (APs) attempting to gain access to the wireless channel may transmit reservation signals to reserve one or more scheduled service periods within the second time period of the same coordinated medium interval. The scheduled service periods reserved by an individual AP may be used for UL/DL communications between that AP and its associated stations (STAs).

摘要： An information processing device includes a control unit. A first device that transmits data to the information processing device has a multiplexing function for multiplexing and transmitting data from a plurality of devices including the first device to the information processing device. The control unit provided in the information processing device performs control to tell the first device having the multiplexing function a multiplexing method for notification information and presence of data addressed to the first device. The notification information indicates that the first device has shifted from a functional suspension state to a data receivable state. The information processing device can reduce power consumption.

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.

摘要： Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a transmission configuration for a first random access message based at least in part on one or more parameters associated with a target base station for initiating a backhaul connection. The transmission configuration may include information associated with a physical random access channel (PRACH) resource associated with transmitting the first random access message. The PRACH resource differs from a PRACH resource associated with a transmission of a random access message by a user equipment. The base station may transmit the first random access message using the transmission configuration. Numerous other aspects are provided.
