CPC H04W 72/23 (2023.01) [H04L 1/1819 (2013.01); H04W 92/18 (2013.01)] | 9 Claims |
1. An information transmission apparatus, comprising:
a receiver configured to receive configuration information transmitted by a network device, the configuration information configuring information of at least one hybrid automatic repeat request process for one of at least two configuration grants;
a processor configured to be configured with and activated, or, configured with or activated the at least two configuration grants, the at least two configuration grants being respectively configured with corresponding hybrid automatic repeat request processes; and
a transmitter configured to transmit uplink data or sidelink data by using the at least two configuration grants;
wherein the configuration information comprises a configuration index of the configuration grant, a start identifier of at least one hybrid automatic repeat request process and the number of the hybrid automatic repeat request processes;
and an identifier of a hybrid automatic repeat request process corresponding to the configuration grant i is calculated by using the following formula:
HARQ Process ID(i)=[floor(CURRENT symbol/periodicity(i))]modulo nrofHARQ-Processes(i)+HARQ process start ID(i);
where, HARQ Process ID (i) is the identifier of the hybrid automatic repeat request process corresponding to the configuration grant i, floor( )denotes a rounded down operation, modulo( )denotes a modulo operation, CURRENT symbol denotes a current symbol where the configuration grant i is located, periodicity (i) denotes a periodicity of the configuration grant i, HARQ process start ID (i) denotes the start identifier configured for the configuration grant i, and nrofHARQ-Processes (i) denotes the number of the hybrid automatic repeat request processes configured for the configuration grant i.
