Techniques in configured grant uplink transmission in new radio (NR) systems operating in unlicensed spectrum
摘要
說明書
As used herein, the term “circuitry” may refer to, be part of, or include any combination of integrated circuits (for example, a field-programmable gate array (FPGA), an application specific integrated circuit (ASIC), etc.), discrete circuits, combinational logic circuits, system on a chip (SOC), system in a package (SiP), that provides the described functionality. In some embodiments, the circuitry may execute one or more software or firmware modules to provide the described functions. In some embodiments, circuitry may include logic, at least partially operable in hardware.
As used herein, the term “configured grant (CG) UL transmission” may refer to, be part of, or include a UL transmission without grant from anchored base station. Further, “autonomous UL transmission,” “grant-free UL transmission,” “grantless UL transmission (GUL),” and “UL transmission without dynamic grant” are used interchangeably throughout the discussions herein.
As earlier discussed, a CG UL transmission may improve or mitigate the impact caused by the quadruple contention for a UE to access a UL transmission in an unlicensed spectrum. Accordingly, an activation and deactivation of the CG UL may be needed to activate and/or deactivate the CG in the NR network operating in an unlicensed spectrum. A grant-free transmission for New Radio (NR) operating on unlicensed spectrum may address the above-mentioned concerns. In the grant-free transmission for NR operating on unlicensed spectrum, new techniques may be required in handling activation/deactivation of CG UL transmission and other related solutions in this regard. Various embodiments herein addresses how the CG UL may be activated and/or deactivated and corresponding acknowledgement of the activation/deactivation of the CG UL, to avoid or reduce any mismatch and/or improve system performance.
