Methods, apparatuses and systems for flexible channel access in shared spectrum
Methods, systems, and devices for wireless communication are described. A wireless device may perform a listen before talk (LBT) procedure on a channel bandwidth using an energy detection (ED) threshold. The ED threshold being associated with a transmission bandwidth that is narrower than the channel bandwidth. The wireless device may also, responsive to a successful LBT procedure, transmit on the transmission bandwidth according to a frequency hopping pattern during a first channel occupancy time (COT). The frequency hopping pattern comprises a first resource allocation and a second resource allocation different from the first resource allocation.
Vehicle-to-everything (V2X) inter-user equipment (UE) coordination
A method for wireless communication performed by a sensing user equipment (UE) includes identifying resource availability during a sensing window. The method further includes receiving a request to share resource information with a transmitter UE. The method still further includes determining a sharing condition is satisfied. The method also includes sharing the resource availability with the transmitter UE based on satisfying the sharing condition.
Dynamic reclamation of resources reserved for forward compatibility
Certain aspects of the present disclosure relate to methods and apparatus for dynamic reclamation of resources reserved for forward compatibility using communications systems operating according to new radio (NR) technologies. Certain aspects provide a method for wireless communication. The method generally includes identifying resources previously reserved for forward compatibility (FC) that are available for reuse, and providing signaling, to one or more user equipments (UEs), indicating the identified resources are available for reuse.

Listen-before-talk (LBT) failure detection in dormant cell and outside discontinuous reception (DRX) active time
Wireless communications systems and methods related to communications in a network are provided. A UE receives a listen-before-talk (LBT) failure detection configuration associated with at least one of a dormant mode or a discontinuous reception (DRX) cycle in a first cell of a wireless communication network. The UE performs, based on the LBT failure detection configuration, an LBT failure detection in the first cell while operating in the dormant mode for the first cell or during an inactive DRX configured-on duration of the DRX cycle. The UE transmits an LBT failure detection report based on the LBT failure detection.
Rach procedures in new radio-unlicensed (NR-U)
Systems and methods related to UL communications in a wireless network are provided. A UE receives an indication of a plurality of TXOPs for a RACH procedure from a BS. In an embodiment, the UE starts a timer after either successfully transmitting a random access message to the BS or failing to succeed in any of the TXOPs. In another embodiment, the UE starts the timer at a pre-agreed time after one of the TXOPs, regardless of whether the random access message has been successfully transmitted yet or not. In another embodiment, the UE receives as part of a RACH response an indication of whether the RACH response is split into multiple parts. If the UE does not locate an identifier corresponding to the UE in the RACH response, the UE checks for the indication and, if present, listen for the next RACH response identified from the indication.
Method and device in UE and base station for identifying start time of transmission using subcarrier spacing information used for wireless communication
The present disclosure provides a method and a device in a UE and a base station for wireless communications. The UE receives first information, and transmits a first radio signal in a first time window in a first sub-band. The first information is used for determining the first time window; a time offset of a start time for a transmission of the first radio signal relative to a reference time belongs to a target offset set, the target offset set including W offset value(s); time offset(s) of W start time(s) respectively relative to the reference time is(are) respectively equal to the W offset value(s); any of the W start time(s) belongs to one of N time units, any of the N time units includes at least one of the W start times.

Co-channel co-existence in a wireless communications system
There are provided mechanisms for sharing channels in a wireless communications system among wireless devices that use a plurality of different access technologies. First and second wireless devices are operable to share a channel in the wireless communication system with each other. The first wireless device is operable to provide an indication to the second wireless device that the first wireless device is using a first access technology to access the channel. The second wireless device is operable to receive the indication and determine, based on the indication, that the first wireless device is using a first access technology to access the channel. Accordingly, the second wireless device can determine, based on compatibility of its access technology with that of the first wireless device, whether to refrain from using the channel or to share the channel.
