Abstract

técnicas para atualizar tamanho de janela de contenção.trata-se de técnicas para definir uma duração de referência e uma ou mais transmissões de referência que são utilizadas para atualização de janela de contenção para abordar esses novos recursos. um aparelho, como um dispositivo sem fio, determina uma duração de referência de um tempo de ocupação de canal (cot), a duração de referência com base pelo menos em parte em um espaçamento de subportadora (scs) e com base na recepção de uma transmissão de canal físico compartilhado de enlace descendente (pdsch). o aparelho atualiza uma janela de contenção (cw) com base pelo menos em parte na recepção da transmissão de pdsch durante a duração de referência. por exemplo, o aparelho pode aumentar a cw quando uma confirmação negativa (nack) é recebida para o determinado pdsch no cot e pode atribuir a cw com um valor mínimo predeterminado (cw_min) quando uma confirmação positiva (ack) é recebida para o determinado pdsch.techniques for updating contention window size. these are techniques for defining a reference duration and one or more reference streams that are used for contention window updating to address these new features. a device, such as a wireless device, determines a reference duration of a channel occupation time (cot), the reference duration based at least in part on a subcarrier spacing (scs) and based on the reception of a downlink shared physical channel (PDSCH) transmission. the device updates a contention window (cw) based at least in part on the reception of the pdsch transmission during the reference duration. for example, the device can increase cw when a negative acknowledgment (nack) is received for the given pdsch in the cot and can assign the cw with a predetermined minimum value (cw_min) when a positive acknowledgment (ack) is received for the given pdsch .
