Method and apparatus for multiple PUSCH transmissions over unlicensed spectrum

Abstract

Embodiments of the present disclosure relate to methods and devices for multiple physical uplink shared channel (PUSCH) transmissions on unlicensed spectrum. According to embodiments of the present disclosure, a method for wireless communication performed by a user equipment includes: receiving one or more signals from a base station to allocate multiple PUSCHs for transmitting uplink data, wherein the multiple PUSCHs are continuous in the time domain; dividing the multiple PUSCHs into a first group of PUSCHs and a second group of PUSCHs, and further dividing the uplink data into a first part of the uplink data and a second part of the uplink data, wherein the first group of PUSCHs is used to transmit the first part of the uplink data and the second group of PUSCHs is used to transmit the second part of the uplink data; performing at least one channel access procedure to transmit the first part of the uplink data using the first group of PUSCHs and to transmit the second part of the uplink data using the second group of PUSCHs.
