The satellite communication system is composed of a satellite part and a ground part. The satellite communication is characterized in that: the communication range is large; any two points can be communicated only in the range covered by the electric wave emitted by the satellite; is not easily affected by land disasters and has high reliability.

Satellite communication is used as a supplement of a ground communication system, and has the following characteristics: 1. the cover may be extended: for areas where the cellular communication system cannot cover or cover high cost, such as oceans, deserts, remote mountainous areas and the like, the problem of communication can be solved by satellite communication. 2. Emergency communication: in conditions where the infrastructure for cellular communications is unavailable due to extreme conditions in which a disaster (e.g., an earthquake, etc.) occurs, a communication connection can be established quickly using satellite communications. 3. Industry applications are provided: for example, for long-distance transmission delay sensitive services, the delay of service transmission can be reduced by satellite communication.

It is expected that in future wireless communication systems, the satellite communication system and the terrestrial cellular communication system will gradually achieve deep convergence, and truly achieve intelligent networking.

In some embodiments, in the satellite communication scenario, there is a longer signal transmission distance between the transmitting end and the receiving end, resulting in a longer time for data transmission. For transmissions with uplink and downlink relations, an offset parameter (Koffset) may be introduced to compensate for the transmission delay. Wherein K is _offset Can be applied in various scenarios, such as: physical uplink shared channel (physical uplink shared channel, PUSCH) transmission scheduled by downlink control information (downlink control information, DCI), transmission of HARQ feedback information, transmission of a medium access control (media access control, MAC) Control Element (CE), and the like.

In some embodiments, fig. 1B is a schematic diagram illustrating HARQ blocking occurring at a terminal in an NTN scenario according to an embodiment of the present disclosure. As shown in fig. 1B, the terminal is configured with one HARQ process (HRAQ process). Due to the large delay of satellite communication systems, HARQ blocking problems may occur for terminals (e.g., ioT devices), thereby reducing the transmission rate of the terminal. Optionally, in other scenarios with a larger delay, the terminal may also have a problem of HARQ blocking, thereby reducing the transmission rate of the terminal. Thus, embodiments of the present disclosure may be applied to other scenarios with larger delays, as the case may be.

1. HARQ states of HARQ processes

In the disclosed embodiments, for IoT devices, the HARQ status of the configured HARQ process may be determined by semi-static configuration from the network device. It is also possible that an indication of a DCI may be received, which may cover the HARQ states of HARQ processes in a semi-static configuration.

In the disclosed embodiments, "overlay" may be interchanged with terms "overwrite," "reconfigure," "change," "modify," "adjust," "update," and the like.

In the embodiments of the present disclosure, the term "HARQ state" may be replaced with terms such as "HARQ feedback state", "HARQ acknowledgement state", and the like.

In some embodiments, to achieve flexible configuration, system performance is improved, and HARQ states of HARQ processes may also be indicated or covered by HARQ feedback resource information. If the indication is an indication of the HARQ state of the HARQ process by DCI, this may be referred to as a DCI-based indication (DCI based indication); if the coverage is performed by indicating the HARQ status of the HARQ process by DCI, this may be referred to as DCI-based coverage (DCI based overriding).

In some embodiments, the HARQ feedback resource information is carried in a HARQ feedback resource field in the DCI. The HARQ feedback resource may be "determine acknowledgement/negative acknowledgement resource field (ACK NACK resource)", "HARQ acknowledgement resource field (HARQ ACK resource)", etc. The HARQ feedback resource field may be "ACK NACK resource field", "HARQ ACK resource field", etc.

Table 1 illustrates an example of a HARQ feedback resource set. The set of HARQ feedback resources comprises 16 HARQ states, each HARQ state corresponding to an allocated subcarrier and a time domain offset k ₀ Is assigned a time domain offset k ₀ For determining the resources (which may also be referred to as HARQ feedback resources) used by the HARQ process in transmitting HARQ feedback. When indicating or covering one HARQ state of the HARQ process by DCI, the HARQ feedback resource field of DCI is used for indicating the HARQ processSubcarrier numbers corresponding to the allocated HARQ states and time offsets k ₀ 。

Referring to table 1 below, the number of subcarriers that may be allocated in the frequency domain may be one value of the set {0, 1, 2, 3}, time domain offset k ₀ The value of (c) may be one of the values in the set 13, 15, 17, 18. ACK/NACK resource field in DCI is 4bits, wherein 2bits are used for indicating the number of the subcarrier, and 2bits are used for indicating the time domain offset k ₀ 。

In the disclosed embodiments, "disable" may be interchangeable with terms of "disable," "disable," and the like.

In some embodiments, for a certain HRAQ process, if HARQ disabling is configured, no corresponding resources need to be allocated for that HARQ.
