当上行链路传输在时间上重叠至少一个符号持续时间时用于上行链路功率控制的方法和装置
Abstract:
一种方法和装置以减少的延迟对上行链路传输进行调度。可在设备处基于与第一TTI长度相关联的较高层配置的功率控制参数的第一集合来确定(1030)第一上行链路传输的第一传输功率。第一上行链路传输可横跨第一TTI长度。第一TTI长度可包括第一数目的符号。可基于与第二TTI长度相关联的较高层配置的功率控制参数的第二集合来确定(1040)第二上行链路传输的第二传输功率。第二上行链路传输可横跨所述第二TTI长度。第二TTI长度可包括第二数目的符号。可在子帧中使用第一传输功率来发送(1050)第一上行链路传输。可在子帧中使用第二传输功率来发送(1060)至少第二上行链路传输。第一上行链路传输和第二上行链路传输可在时间上重叠至少一个符号持续时间。
Abstract(English):

A method and apparatus schedule uplink transmissions with reduced latency. A first transmission power of a first uplink transmission can be determined at a device based on a first set of higher layer configured power control parameters associated with a first TTI length. A higher layer can be higher than a physical layer. The first uplink transmission can span the first TTI length. The first TTI length can include a first number of symbols. A second transmission power of a second uplink transmission can be determined based on a second set of higher layer configured power control parameters associated with a second TTI length. The second uplink transmission can span the second TTI length. The second TTI length can include a second number of symbols. The second number can be different from the first number. The first uplink transmission can be transmitted in a subframe using the first transmission power. At least the second uplink transmission can be transmitted in the subframe using the second transmission power. The first uplink transmission and the second uplink transmission can overlap in time for at least one symbol duration.
