Title: Methods and apparatus for sidelink communications on unlicensed spectrum
Inventor: CHENG JUNQIANG
IPC: H04W74/08
Filed: 2022-02-11
Abstract: This disclosure describes methods and apparatus for sidelink communications on unlicensed spectrum. Each sidelink device may perform independent and asynchronous sensing mechanism to collect the sensing information of the unlicensed spectrum. Then before the device can access the unlicensed spectrum, it should execute channel access (LBT) procedures to judge the state of the unlicensed spectrum. The sensing results can be used to assist the channel access procedures to reduce the device power consumption. Besides, to combat channel access failure, the random back-off counter generation time and/or the channel access trigger time and/or the number of resource overbooking and/or the gap between LBT successful position and resource selection/reservation position can be configured/indicated dependently or independently according to the channel status and/or the layer1 priority. Only when the channel access is successful, the device can occupy the corresponding unlicensed spectrum in the following COT. The COT can be used by the initiating device only and can also be shared to the other devices in the group. Within the COT, the initiating device should execute sidelink resource selection procedures to select/reserve resources for the current and/or the next traffic (re-) transmission. The resources reserved by the other devices within the COT can be shared to the corresponding devices by the initiating device. If the resources are reserved within the current COT, Type 2 channel access (s) can be configured for the device to execute before the reserved resources. If the resources are reserved out of the current COT, Type 1 channel access can be configured for the device to initiate a new COT before the reserved resource. For the latter case, the device may switch from Type 1 channel access to Type 2A channel access if the ideal resources are within the determined COT duration shared from another device. Moreover, the channel access type can be scheduled/configured by the initiating device/cluster header, and/or can be determined by the sharing device/cluster member according to the gap between two consecutive transmissions in the COT.
