In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a time unit determining method, a terminal, a network device and a storage medium, so as to solve the problem that the reliability of uplink transmission is poor.

The method and the equipment are based on the same application concept, and because the principles of solving the problems of the method and the equipment are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not described again.

The technical scheme provided by the embodiment of the application can be suitable for various systems, especially 6G systems. For example, suitable systems may be global system for mobile communications (GSM) systems, code Division Multiple Access (CDMA) systems, wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) systems, long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, long term evolution (long term evolution) systems, LTE-a systems, universal mobile systems (universal mobile telecommunications systems, UMTS), universal internet Access (world interoperability for microwave Access (WiMAX) systems, new G6 Radio systems, etc. These various systems include terminal devices and network devices. The System may further include a core network portion, such as an Evolved Packet System (EPS), a 5G System (5 GS), and the like.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a network architecture to which the present application is applicable, and as shown in fig. 1, includes a terminal 11 and a network device 12.

The terminal according to the embodiments of the present application may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be referred to as a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile phone (or called a "cellular" phone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN), and may exchange languages and/or data with the RAN. For example, devices such as Personal Communication Service (PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless Local Loop (WLL) stations, personal Digital Assistants (PDAs), redcap terminals, and Low Power Wide Area (LPWA) terminals. The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in this embodiment of the present application.

The network device according to the embodiment of the present application may be a satellite, or a base station on a satellite, where the base station may include multiple cells for serving a terminal. A base station may also be called an access point, or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network device may be configured to exchange received air frames and Internet Protocol (IP) packets with one another as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communications network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiment of the present application may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) or a Code Division Multiple Access (CDMA), may be a network device (NodeB) in a Wide-band Code Division Multiple Access (WCDMA), may be an evolved Node B (eNB) or an e-NodeB) in a Long Term Evolution (LTE) System, may be a Base Station (gNB) in a 5G network architecture (next generation System), may be a Home evolved Node B (Home evolved Node B, nodeB), a relay Node (relay Node), a Home Base Station (femto), a pico Base Station (pico), and the like. In some network architectures, a network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

The network device and the terminal may each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission, and the MIMO transmission may be Single User MIMO (SU-MIMO) or Multi-User MIMO (MU-MIMO). According to the form and the number of the root antenna combination, the MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, and can also be diversity transmission, precoding transmission, beamforming transmission, etc.

Flexible timing relationships are supported in a 5G NR system. For the PUCCH, the PDCCH scheduling PDSCH or the PDCCH that needs HARQ-ACK feedback (e.g., the PDCCH indicating SPS resource release, the PDCCH indicating secondary cell (SCell) dormancy (dormant), etc.) includes an indication field of feedback timing, and the indication field indicates a time interval (i.e., K1) between the scheduled PDSCH or the PDCCH that needs HARQ-ACK feedback and the PUCCH that carries HARQ-ACK feedback, i.e., indicates a feedback timing relationship or feedback timing (HARQ timing). Specifically, the DCI used by the PDCCH includes a PDSCH-to-HARQ-ACK feedback timing indication field, where the indication field indicates the number k1 of time slots from the ending position of the PDSCH or the PDCCH that needs to perform HARQ-ACK feedback to the starting position of the HARQ-ACK, or may be a time slot offset between the time slot in which the PDSCH or the PDCCH is located and the time slot in which the HARQ-ACK is located. For example, the PDSCH ending at time slot n is HARQ-ACK transmitted in time slot n + k1, as shown in fig. 2. The full set of k1 is {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}, and the value of k1 may be in units of slots, i.e., k1=1 represents a 1 slot interval. The higher layer signaling configures a K1 set in advance, and can contain one or more K1 values. When only 1 k1 value is included, it is described that one-to-one HARQ-ACK feedback is performed, and the DCI does not need to include a feedback timing indication field; when a plurality of k1 values are contained, one k1 value is indicated through an indication domain in the DCI, a k1 set contains 8 k1 values at most in consideration of DCI indication overhead, a value meeting the minimum processing delay of a terminal is selected from 16 values of 0-15 by high-layer signaling and is configured to the terminal, and the bit number of a feedback timing indication domain in the DCI changes along with the size of the k1 set and is 3 bits at most. When the PDSCH or the PDCCH and the PUCCH which need to be subjected to HARQ-ACK feedback have different subcarrier intervals, k1=0 corresponds to a last PUCCH slot (i.e., a slot divided by the subcarrier interval of the PUCCH) overlapping the received PDSCH or the PDCCH which needs to be subjected to HARQ-ACK feedback.

For the PUSCH, the PDCCH carrying the Scheduling information thereof includes a Scheduling timing indication field indicating the PUSCH and the PDCCH, and indicates a time interval (i.e., k 2) between the PDCCH and the PUSCH, that is, the Scheduling timing indication field indicates a Scheduling timing relationship or Scheduling timing (Scheduling timing). Specifically, the time domain resource allocation indication field in the DCI used by the PDCCH indicates the time slot offset k2 between the time slot in which the PUSCH is located and the time slot in which the PDCCH is located, that is, the PDCCH of time slot n indicates that PUSCH transmission is performed in time slot n + k2, as shown in fig. 3. The full set of k2 is {0,1,2,3,4, \8230;, 32}, and is typically configured to the terminal with a maximum of 16 values through a Time Domain Resource Allocation (TDRA) table. The value of k2 may be in units of slots, i.e. k2=1 denotes an interval of 1 slot. When the PDCCH and PUSCH have different subcarrier spacings, k2=0 corresponds to the first PUSCH slot overlapping the slot in which the PDCCH was received (i.e., the slot divided by the subcarrier spacing of the PUSCH).

The values of k1 and k2 are mainly given consideration to processing delay and Timing Advance (TA) to select appropriate values to be notified to the terminal, that is, it is ensured that the actual start position of uplink transmission and downlink transmission do not overlap, and the analysis of downlink transmission and the preparation of uplink transmission can be completed. For example, as shown in fig. 2, if the processing delay is 1 timeslot and the TA value is 1 timeslot, K1 is at least 2, which means that downlink transmission in timeslot n and HARQ-ACK transmission in timeslot n +2 are performed. Specifically, according to TA, the actual transmission time of the PUCCH carrying the HARQ-ACK in slot n +2 is slot n +1, and the processing delay of 1 slot may be satisfied between slot n +1 and slot n, so as to ensure that preparation is completed before transmission on the time domain resource corresponding to the PUCCH in slot n + 1.

For the feedback timing in satellite communication, considering that the distance between the satellite and the ground is far, the required TA advance is much larger than the designed k1 value of the ground system, and therefore the k1 value of the ground system cannot cover the whole TA requirement of satellite transmission. It may be considered to introduce a semi-static configuration of fixed offset values K _offset Parameters, usually in ms, as a compensation value for TA between the satellite and a near-ground reference point, based on K1 and K _offset To jointly determine the HARQ-ACK transmission slot. As shown in fig. 4, the terminal receives PDSCH in time slot n, and in time slot

Performs HARQ-ACK. Wherein, K _offset Value configured for higher layer signaling (to compensate for satellite TA), in ms, μ _PUCCH Is the number of the subcarrier spacing corresponding to the PUCCH (the number in NR, e.g., the subcarrier spacing is 120kHz, then μ _PUCCH =3, meaning that 8 slots are included in 1ms, K _offset ms is equivalent to 8 XK _offset One time slot),

the aim is to give K in ms _offset The number of slots corresponding to the subcarrier interval converted into the PUCCH, and k1 is a value of the feedback timing defined in NR. PUSCH is similarly by K2 and K _offset To determine the scheduling timing, i.e.

μ _PUSCH The number of the subcarrier interval corresponding to the PUSCH is used.

It should be noted that, the above description only uses time units as time slots for illustration, and the present application is not limited thereto.

Referring to fig. 5, fig. 5 is a flowchart of a time unit determining method provided in the embodiment of the present application, and as shown in fig. 5, the method includes the following steps:

step 501, a terminal acquires one or more first offset values configured by a network device, wherein when only one first offset value is configured, the first offset value is related to a beam scanning period;

step 502, the terminal determines a time unit of uplink transmission according to a target first offset value;

The one or more first offset values may be configured to the terminal by the network device in a semi-static manner, for example: the one or more first offset values may be configured semi-statically through a high layer signaling or a Medium Access Control Element (MAC CE). If a plurality of first offset values are configured, a portion of the first offset values may be configured for higher layer signaling, and another portion of the first offset values may be some offset values indicated by the MAC CE among a plurality of offset values pre-configured for higher layer signaling.

When only one first offset value is configured, the first offset value is associated with the beam sweep period, which means that when a plurality of first offset values are configured, the plurality of first offset values are not limited to be associated with the beam sweep period.

In this embodiment of the present application, the beam scanning periods and/or beam scanning patterns of uplink transmission and downlink transmission may be the same or different, that is, only one beam scanning period and/or beam scanning pattern period may be defined, and uplink transmission and downlink transmission are shared, for example, in fig. 6, in one beam scanning period, downlink transmission may be performed in a time period serving for UE1, and uplink transmission may also be performed; a beam scanning period and/or a beam scanning pattern period may also be separately defined for uplink transmission and downlink transmission, for example, in the same beam scanning period, the time period of the serving terminal or the beam position is different for uplink transmission and downlink transmission, as shown in fig. 7, where in the same beam scanning period, the downlink transmission time serving for UE1 is 10ms, the uplink transmission time serving for UE1 is 10ms later, and the uplink and downlink service times are different. Of course, the above is merely an example, and other cases such as the uplink service time and the downlink service time partially overlapping may be also possible. In the case that the beam scanning periods and/or patterns of the uplink transmission and the downlink transmission are different, the determining whether the first target time unit is in the service time period of the current terminal or the current wave position may be determining whether the first target time unit is in the service time period of the uplink beam serving the current terminal or the current wave position.

In this embodiment, when a service time period of a current terminal or a current wave position, specifically, a beam of a satellite serves multiple terminals or multiple wave positions in a beam hopping manner, the beam serves different terminals or wave positions according to a beam scanning pattern defined in a fixed period, so that a service time period in which the beam serves the current terminal or the current wave position in one period can be obtained based on the beam scanning pattern and the period, and only in a time in which the beam serves the terminal or the wave position, downlink transmission sent by a base station to the terminal can be received by the terminal, and uplink transmission sent by the terminal to the base station can be received by the base station similarly. The terminal can be informed by broadcasting a beam scanning period and a pattern corresponding to a certain terminal or wave position in advance, and a beam serves the terminal or the service time of the wave position of the terminal, so that the terminal can determine a time unit contained in a beam service time slot according to the beam scanning period and the pattern to perform uplink transmission.

When a plurality of first offset values are configured, the target first offset value may be one first offset value selected by the terminal from among the plurality of first offset values, for example: selecting a first offset value according to the indication of the network equipment or selecting a first offset value according to the time period of the beam serving the terminal.

In this embodiment, the uplink transmission may include a PUCCH or may include a PUSCH.

The time unit is one of the following items:

subframe, slot, minislot, subslot, symbol.

Therefore, the subframe, the time slot, the micro time slot, the sub time slot or the symbol where the uplink transmission is located can be determined according to the target first offset value.

In the embodiment of the present application, only one first offset value related to the beam scanning period and the beam scanning pattern is configured, or a plurality of candidate first offset values are configured to meet different time interval requirements, so that compared with the prior art that the time unit where the uplink transmission is located is determined only according to one time interval (for example, k1 or k 2) configured by the network device and taking a time slot as a unit, the time unit where the uplink transmission is located can be determined in the present application embodiment by determining the service time period of the current terminal or the current wave bit, and further by determining that the time unit where the uplink transmission is located in the service time period of the current terminal or the current wave bit, so as to ensure normal uplink transmission.

As an alternative embodiment, in the case that only one first offset value is configured, the first offset value is a first type value or a second type value;

Wherein the first type of value is a value of an integer multiple of the beam scanning period (so as to ensure that the time unit of uplink transmission determined according to an offset of an integer multiple of the beam scanning period is in the service time period based on a time unit corresponding to downlink transmission in the service time period, where the integer multiple of the beam scanning period is a transmission delay that can satisfy satellite transmission (i.e., K defined in the existing satellite system) _offset ) The sum of the requirements of the transmission delay and the processing time of the terrestrial cell (i.e., K1 defined for PUCCH transmission and K2 defined for PUSCH transmission in a 5G system) should be the minimum value to satisfy the above requirements in terms of considering the delay, that is, the multiple of the integer is to ensure that the integral multiple of the beam period satisfies the requirementThe smallest integer of the above requirements);

the second type of value is the sum of an integer multiple of the beam scanning period and the length of time that the terminal is not served during the beam scanning period (from the viewpoint of considering the delay, the integer multiple is a multiple satisfying the condition that the sum is not less than the transmission delay of the satellite transmission (i.e. K defined in the existing satellite system) _offset ) A minimum integer value of the sum of the requirements of the transmission delay and the processing time of the terrestrial cell (i.e., K1 defined for PUCCH transmission and K2 defined for PUSCH transmission in the 5G system) may be 0, for example, the length of time during which the terminal is not served in the beam scanning period may be not less than the transmission delay of the satellite transmission (i.e., K defined in the existing satellite system) _offset ) The second type of value may be only the length of time that the terminal is not served in the beam sweep period when the sum of the requirements of the transmission delay and the processing time of the terrestrial cell (i.e., K1 defined for PUCCH transmission and K2 defined for PUSCH transmission in 5G system) is equal to or,

the second type of value is a sum of an integer multiple of the beam sweep period, a length of time in the beam sweep period that the terminal is not served, and a second offset value, or,

the second type of value is a length of time that the terminal is not served in the beam scanning period (so that some downlink transmissions in later time units in the service period in the current beam scanning period are compared with each other, and the time unit for obtaining the corresponding uplink transmission based on such second type of value is in earlier time units in the service period that the terminal or the wave position is served in the next beam scanning period, thereby avoiding a situation that some time units in the service time cannot be scheduled for uplink transmission because downlink transmissions in one time unit in the service period in the current beam scanning period are always scheduled for uplink transmission in one time unit at the same position in the next beam scanning period if the downlink transmissions in one time unit in the service period in the current beam scanning period are always in integer multiples of the beam period), or,

The second type of value is a sum of a length of time that the terminal is not served in the beam sweep period and the second offset value, or,

the second type of value is an offset value between the beamscan pattern of the uplink beam and the beamscan pattern of the downlink beam, or,

the second type of value is that a time interval between a time unit of the downlink transmission and a time unit of the uplink beam serving the current terminal or the current wave position in the scanning pattern of the uplink beam after the time unit of the downlink transmission is quantized to a time length in units of the first time unit (for example, if the time length is Z time slots, the Z time slots are converted to a time length in units of ms, and if the number of the subcarrier interval of the uplink transmission is μ, the ceil (Z/2) is passed through ^μ ) Where ceil () represents rounding up), or,

the second type of value is a time interval between a subframe corresponding to a time unit where the downlink transmission is located and a subframe serving a current terminal or a current wave position in a first scanning pattern of an uplink wave beam behind the subframe; (i.e. in a period, an offset value between uplink time and downlink time of the same terminal or wave position served by the terminal, or, an offset value between a starting position of a scanning pattern of an uplink beam in a scanning period and a starting position of a scanning pattern of a downlink beam in a scanning period, or directly defined as an offset value between uplink time and downlink time of the same terminal or wave position served by the terminal, that is, only an offset value between a starting position of uplink service time and a starting position of downlink service time of the same terminal or wave position served by the terminal is considered regardless of whether uplink and downlink beam periods are the same); for example, in the beam velocity scan pattern shown in fig. 7, in the same beam scan period, for the terminal 1, the offset value between the service time periods of the uplink beam and the downlink beam is 10ms, that is, the offset value between the downlink position serving the terminal 1 first and the uplink position serving the UE1 first), or K _offset3 For the offset value between the beam scanning pattern of the uplink beam and the beam scanning pattern of the downlink beam and the length of time in the beam scanning period that the current terminal or the current wave position is not served (i.e., the uplink beam is scanned)The length of time in the period that is determined by the beamsweeping pattern not to serve the current terminal or the current wave position). Or,

the second type of value is a sum of an offset value between the beam scan pattern of the uplink beam and the beam scan pattern of the downlink beam and an integer multiple of the scan period of the uplink beam, or,

the second type of value is an offset value between the beam scan pattern of the uplink beam and the beam scan pattern of the downlink beam, and a sum of an integer multiple of the scan period of the uplink beam and a second offset value, or,

the second type of value is an offset value between a beam scan pattern of an uplink beam and a beam scan pattern of a downlink beam, an integer multiple of an uplink beam scan period, a sum of lengths of time not serving the terminal in the uplink beam scan period, or,

the second type of value is an offset value between a beam scan pattern of an uplink beam and a beam scan pattern of a downlink beam, an integer multiple of an uplink beam scan period, a sum of a length of time that the terminal is not served in the uplink beam scan period and a second offset value, or,

The second type of value is a sum of an offset value between a beam scan pattern of an uplink beam and a beam scan pattern of a downlink beam, a length of time the terminal is not served in an uplink beam scan period, or,

the second type of value is a sum of an offset value between a beam scanning pattern of an uplink beam and a beam scanning pattern of a downlink beam, a time length during which the terminal is not served in an uplink beam scanning period, and a second offset value;

in the above manner of determining the second type of value, if the second offset value is not considered, the principle of determining the second type of value is that the determined second type of value is not smaller than the second offset value, so that the requirement of the second offset value can be directly included in the factors already considered in the second type of value.

In the embodiment of the present application, in the same beam scanning period, the time period of serving the terminal or the wave position is different for the uplink transmission and the downlink transmission, as shown in fig. 7, in the same beam scanning period, the downlink transmission time serving the terminal 1 is 10ms before, the uplink transmission time serving the terminal 1 is 10ms after, and the uplink and downlink service times are different. Of course, the above is merely an example, and other cases such as the uplink service time and the downlink service time partially overlapping may be also possible. In the case that the beam scanning periods and/or patterns of the uplink transmission and the downlink transmission are different, the determining whether the first target time unit is in the service time period of the current terminal or the current wave position may be determining whether the first target time unit is in the service time period of the uplink beam serving the current terminal or the current wave position.

That is, in one period, an offset value between an uplink time and a downlink time of the same terminal or wave position, or an offset value between a start position of a scan pattern of an uplink beam in one scan period and a start position of a scan pattern of a downlink beam in one scan period, or directly defined as an offset value between an uplink time and a downlink time of the same terminal or wave position (that is, only an offset value between a start position of an uplink service time and a start position of a downlink service time of the same terminal or wave position is considered regardless of whether uplink and downlink beam periods are the same, that is, regardless of whether uplink and downlink beam periods are the same); for example, in the wave velocity scan pattern shown in fig. 7, in the same beam scan cycle, for UE1, the offset value between the service time periods of the uplink beam and the downlink beam is 10ms, that is, the offset value between the downlink position serving UE1 first and the uplink position serving UE1 first.

In the embodiment of the present application, the second type of value may be defined without considering the second offset value, and actually the second type of value itself includes the second offset value, that is, the value of the second value is not less than the value of the second offset value.

The integral multiple of the beam scanning period may be an integral multiple of a beam scanning period predetermined or configured by the network device, and a specific multiple thereof is not limited.

The second offset value may be an adjustment value related to Round-Trip Time (RTT) or Timing Advance (TA) of satellite-to-ground communication. In addition, the second offset value may be pre-agreed or configured by the network device. Specifically, K in the scenario shown in fig. 4 may be _offset K is the same as _offset Are offset values that have been defined in some existing satellite systems.

In this embodiment, the time unit in which the uplink transmission is located, which is determined by the terminal, may be located in the time period in which the beam serves the terminal through the one first offset value.

As an optional implementation, the set of candidate values for the first offset value includes at least one of:

the first class of values, the second class of values;

The second offset value is described with reference to the above embodiments, and is not described herein again.

In this embodiment, the candidate value set of the first offset value includes at least one of the first class value and the second class value, and may be applied to a scenario where one first offset value or a plurality of first offset values are configured, that is, the first offset value related to the beam scanning period may also be configured in a scenario where a plurality of first offset values are configured. For example: the plurality of first offset values include a first type of value, may also include a second type of value, or includes a plurality of first offset values belonging to the first type of value, or includes a plurality of first offset values belonging to the second type of value.

As an optional implementation manner, in a case that a plurality of first offset values are configured, the plurality of first offset values may include the second offset value (see the description of the foregoing implementation manner, which is not described herein again).

Besides the second offset value, the plurality of first offset values may also include other offset values, for example: the one or more values of the first type and/or the second type associated with the beam sweep period, or the plurality of first offset values, comprise a plurality of second offset values, the plurality of second offset values having different values.

As an optional implementation manner, in a case that a plurality of first offset values are configured, the terminal determines the target first offset value according to any one of the following manners:

the second offset value is an offset value in units of a first time unit, a specific first time unit may be ms or a subframe according to the above definition of the second offset value (when a length of one subframe defined in the communication system is fixed to 1ms, ms and the subframe are equivalent in unit), and the third offset value is an offset value in units of a second time unit, where the second time unit is smaller than the time unit of the second offset value. The second time unit may be a time unit of less than 1ms, such as a slot or a sub-slot. For example, the third offset value may be a K1 value (feedback timing) in slots or sub-slots defined for the PUCCH in the 5G communication system to indicate a time interval between the PDSCH (or the PDCCH requiring feedback of the HARQ-ACK) and its HARQ-ACK transmission, and the third offset value may be a K2 value (scheduling timing) in slots or sub-slots defined for the PUSCH in the 5G communication system to indicate a time interval between the PDCCH and the scheduled PUSCH transmission.

The first indication field is an indication field for indicating one first offset value of the plurality of first offset values, that is, a corresponding relationship between each bit state of the first indication field and the indicated first offset value may be predefined or configured, and one first offset value is indicated by different bit states of the first indication field; wherein the number of bits of the first indication field may be determined based on the number of values of the first offset value. For example, as shown in the following table, the 2-bit first indication field is taken as an example (the bit numbers of the other first indication fields are similar and are not described again).

TABLE 1

Bit state of the first indication field	Corresponding first offset value
		00	Offset value 1
01	Offset value 2
		10	Offset value 3
11	Offset value 4

Wherein, the first indication domain is an indication domain defined in the reuse DCI; or the first indication domain is a newly added indication domain in the DCI.

When the first indication domain is an already defined indication domain in the reuse DCI, the first indication domain is reused for an indication domain originally indicating a third offset value in the DCI, wherein the first offset value and the third offset value are jointly encoded and indicated by the first indication domain, or the first offset value is indicated by partial bits in the indication domain originally indicating the third offset value, or the indication domain originally indicating the third offset value is directly reused to only indicate the first offset value.

When the first offset value and the third offset value perform joint coding indication, the relationship between different bit states of the first indication field and a combined state of the first offset value and the third offset value, which are defined or configured in advance, represents the first offset value and the third offset value which are indicated simultaneously, for example, a 3-bit indication field is taken as an example, as shown in the following table, wherein the table only takes the combination of 2 first offset values and 4 third offset values as an example, and the number and the combination condition of other first offset values and third offset values are not excluded; wherein the combining case may be defined separately for PUCCH and PUSCH.

TABLE 2

When the first offset value is indicated by a part of bits in the indication field originally indicating the third offset value, the indication field originally indicating the third offset value may be divided into two parts, where the first part indicates the first offset value and the second part indicates the third offset value, for example, taking a 3-bit indication field originally indicating the third offset value as an example, the indication field may be divided into a part where 1 bit (for example, the upper bit or the lowest bit) indicates the first offset value and the remaining bits indicate the third offset value.

When the indication field originally indicating the third offset value is directly reused to indicate only the first offset value, it means that the third offset value cannot be indicated, one mode considers that the configured first offset value can include the required time of the third offset value, so that the third offset value is not needed, and the other mode considers that a fixed third offset value agreed or configured in advance is used, so that the notification in the DCI is not needed; at this time, taking the indication field originally indicating the third offset value with 3 bits as an example, the third offset value may be obtained based on the first indication field according to the correspondence between the bit state of the indication field and the first offset value given in the following table.

TABLE 3

Bit state of the first indication field	Corresponding first offset value
		000	Offset value 1
001	Offset value 2
		010	Offset value 3
011	Offset value 4
		100	Offset value of 5
101	Offset value 6
		110	Offset value 7
111	Offset value of 8

In the table of the above-mentioned various corresponding relations, it is also possible not to correspond offset values to all bit states, for example, some bit states may be reserved, and corresponding offset values are not defined, so as to support subsequent extension use. Such a mapping definition is also within the scope of the present invention.

and determining the bit number of the first indication domain according to the number of the values of the first offset value. When P first offset values are configured, determining the bit number of the first indication field as ceil (log) ₂ P), where ceil () is a round-up operation; for example, when 4 first offset values are configured, the first indication field is determined to be ceil (log) ₂ 4) If the number of bits is =2, the mapping relation in table 1 may be referred to, and when 8 first offset values are configured, the first indication field is determined to be ceil (log) ₂ 8) =3 bits, the mapping relation in table 3 above may be referred to.

The first mapping relationship may indicate that one of the first offset values corresponding to each of a plurality of time portions may be obtained by dividing a time period serving for the terminal into a plurality of time portions, each of the time portions corresponds to one of the first offset values, and different time portions may be divided in units of ms or in units of time slots. And the first correspondence may be a pre-configured or notified correspondence.

The second offset value is described with reference to the above embodiment, and is not described herein again.

The number of time units corresponding to the second offset value X is defined as K _offset2 ·2 ^μ Wherein, K is _offset2 U is the number of the subcarrier spacing of the uplink channel, which is the second offset value. The time unit obtained from n + X may be obtained from n + K _offset2 ·2 ^μ The resulting time unit.

When Y is the total number of time units corresponding to the second offset value and the third offset value, it can be understood that K + K _offset2 ·2 ^μ Wherein, K is _offset2 K is the second offset value and k is the third offset value. The time unit determined according to n + Y may be determined according to n + K + K _offset2 ·2 ^μ The resulting time unit.

In the case where the uplink transmission is the PUCCH, k may be k1, and in the case where the uplink transmission is the PUSCH, k may be k2. The k1 is an offset value of a time unit where a PDCCH and a PUCCH of a PDSCH which need HARQ-ACK feedback for scheduling defined in the ground communication system are located, or the k1 is an offset value of a time unit where the PDCCH and the PUCCH need HARQ-ACK feedback for self-scheduling. The k2 schedules an offset value of a time unit in which the PDCCH of the PUSCH and the PUSCH are located.

Wherein, when the uplink transmission is a PUSCH transmission, the time unit n is a time unit corresponding to a PDCCH for scheduling the PUSCH; or

The PDCCH is a PDCCH which needs HARQ-ACK feedback; or,

the PDCCH is a PDCCH for scheduling PUSCH.

The PDCCH requiring HARQ-ACK feedback may include: a PDCCH indicating Semi-Persistent Scheduling (SPS) resource release, or a PDCCH indicating Secondary Cell (SCell) dormancy, or the like.

As an optional implementation manner, the determining, by the terminal, the time unit in which the uplink transmission is located according to the target first offset value includes at least one of the following:

numbering as PUCCH when the uplink transmission is PUCCH

Or

The time unit of (2) is used as the time unit of the uplink transmission; wherein n is the number of a time unit corresponding to the PDSCH or PDCCH needing HARQ-ACK feedback on the PUCCH, K1 is an offset value of the time unit of the PDSCH or PDCCH and the PUCCH by taking a second time unit as a unit, and K is the offset value of the time unit of the PDSCH or PDCCH and PUCCH _offset For the target first offset value, μ _PUCCH The number of the subcarrier interval corresponding to the PUCCH is set;

numbering as PUSCH when the uplink transmission is PUSCH

Or

In the above calculation method, when the third offset value (k 1 or k 2) is not considered, the time required for the third offset value is already included in the arranged first offset value.

In this embodiment, numbering as

The time unit of (2) is taken as the time unit of the PUCCH, so that the time unit of the PUCCH is positioned in the time period of the beam serving the terminal. And can realize the editingNumber is

Or

In the embodiment of the application, a terminal acquires one or more first offset values configured by network equipment, wherein when only one first offset value is configured, the first offset value is related to a beam scanning period; the terminal determines a time unit of uplink transmission according to the target first offset value; when only one first offset value is configured, the target first offset value is the configured one first offset value; when a plurality of first offset values are configured, the target first offset value is one of the plurality of first offset values. Therefore, when only one first offset value is configured, the first offset value is related to the beam scanning period, or a plurality of first offset values are configured, so that compared with the prior art that the time unit of uplink transmission is determined only according to the time interval (for example, K1 or K2) configured by the network equipment, the embodiment of the application can ensure that the determined time unit of uplink transmission is within the time period in which the beam serves the terminal, and further support normal uplink transmission in the beam hopping working mode.

It should be noted that, this embodiment is used as an implementation of a network device corresponding to the embodiment shown in fig. 5, and specific implementation of this embodiment may refer to the relevant description of the embodiment shown in fig. 5, so that, in order to avoid repeated descriptions, this embodiment is not described again, and the same beneficial effects may also be achieved.

The method provided by the embodiments of the present invention is illustrated by the following examples:

example 1

This embodiment may be as in the scenario of FIG. 9, with the transmitted subcarriers spaced at 120kHz, i.e., μ _PUSCH ＝μ _PUCCH 8 time slots are contained in 3,1ms; the beam scanning period is 20ms, the first 10ms is allocated to the wave position of the terminal 1 in every 20ms, the last 10ms is allocated to the wave position of the terminal 2, and for the terminal 1, uplink transmission can be performed only in the range of 0-10 ms, 20-30 ms and the like in the figure; assuming that the inherent TA or RTT offset value of the satellite system is 10ms (i.e., the second offset value), according to the beam scanning pattern and period, the base station can know that for the terminal 1, the calculated number of time slots = n +10 · 8= n +80 corresponding to the n + second offset value, and no matter which time slot of the 10ms that serves the terminal 1 in the first period, the calculated target time slot is not in the time period that serves the terminal 1 in the beam scanning period (but in the time period that serves the terminal 2), it can be considered that 1K time slots are configured _offset The value (i.e. first offset value), for example, configured as K _offset =20ms, i.e., 1 times of beam scanning period, the number of integer multiple of the minimum beam scanning period not smaller than the second offset value (10 ms) may be satisfied, such as

PDSCH in a time slot n in the first wave beam scanning period or PDCCH needing HARQ-ACK feedback can be obtained, correspondingly, at the position of the corresponding time slot n in the next wave beam period, the terminal sends HARQ-ACK through the PUCCH, and the base station sends HARQ-ACK through the PUCCHThe PUCCH receives the HARQ-ACK. And correspondingly to the position of the corresponding time slot n in the next beam period, the terminal sends the PUSCH, and the base station receives the PUSCH.

Example 2

This embodiment may be as shown in fig. 10, and the assumption of embodiment 1 is that the time slot obtained by (the number of time slots corresponding to n + the second offset value + the number of time slots corresponding to k 1) is used to determine whether the time slot is within the time period of the beam serving terminal, so as to consider how to select the first offset value; then, considering that k1 can range from 0 to 15, i.e. can cover a maximum time length of 2ms, when the preconfigured k1 set contains a value greater than 7, it means that k1 can bring an offset of 1ms, assuming that the currently configured k1 set contains {8,9,10 }. . .15} the PDSCH in the last slot of 1ms in the first beam scanning period of terminal 1 gets the target slot n + k1+80 based on k1= 8-15 and the second offset =10ms, meaning that it can be transmitted in the time period serving terminal 1 in the second period, so the first offset is enough to use the second offset at this time, and the PDSCH in the first slot of 9ms in the first beam scanning period of terminal 1 always falls in the time period serving terminal 2 based on the second offset =10ms no matter what value k1 takes, so a relatively large first offset needs to be configured for these positions; therefore, 2 first offset values need to be configured, where the first offset value may be 10ms, which corresponds to a slot in the last ms of 10ms serving the terminal 1 in one beam period, and the second first offset value may be 20ms (which is a value that is an integer multiple of the minimum beam scanning period that is not smaller than the second offset value (10 ms)), so that the slot served by the corresponding beam in the second period can be found for HARQ-ACK transmission; therefore, the network device can select two values of 10ms and 20ms to be configured to the terminal as the first value and the second value of the first offset value; and can be realized by any one of the following modes:

Mode 1: indication in DCI dynamically indicates one value to terminal to useBy means of a formula to inform about a certain time slot n

Calculating which K to use when transmitting the slot of HARQ-ACK _offset A value; for example, a second value (20 ms) may be indicated for the case where the PDSCH or the PDCCH requiring feedback of HARQ-ACK is transmitted in slot n in the first 9ms in the UE1 service period in the first cycle, and a first value (10 ms) may be indicated for the case where the PDSCH or the PDCCH requiring feedback of HARQ-ACK is transmitted in slot n in the last 1ms in the UE1 service period in the first cycle; correspondingly, the terminal obtains the first offset value from the received DCI according to the corresponding method, so as to calculate and obtain the time slot for transmitting the HARQ-ACK according to the same method;

mode 2: pre-configuring a corresponding relationship, for example, dividing the first 9ms of 10ms of a service terminal 1 in one cycle into a time period (first time period), dividing the last 1ms into a time period (second time period), respectively agreeing or configuring corresponding first offset values for the first time period and the second time period to be 20ms and 10ms, respectively, so that both the network device and the terminal can determine which first offset value to use according to the actual time slot position of receiving the PDSCH or the PDCCH which needs to perform HARQ-ACK feedback, thereby obtaining a corresponding HARQ-ACK transmission time slot;

Mode 3: the network device and the terminal may determine which first offset value to select according to whether the obtained time slot (the number of time slots corresponding to the (n + second offset value)) or the obtained time slot (the number of time slots corresponding to the (n + second offset value) + the number of time slots corresponding to the k 1) is within the time period of the beam serving the terminal; determining that the target slot calculated in the above manner is not within the service period for the slot in the first 9ms of the 10ms period in one cycle serving the terminal 1, and determining to use the first value (20 ms), and determining that the target slot calculated in the above manner is within the service period for the slot in the last 1ms of the 10ms period in one cycle serving the terminal 1, and determining to use the second value (10 ms);

example 3

This embodiment is implemented on the basis of embodiment 2 above, and if it is desired to avoid out-of-order scheduling, it may be considered to configure a larger first offset value for the last 1ms, for example, 40ms, for the last 9ms of 10ms, the DCI still indicates or is pre-configured or defined to use the first offset value of 20ms, and for the last 1ms of 10ms, the DCI indicates or is pre-configured or defined to use the first offset value of 40 ms.

Example 4

In this embodiment, assuming that the offset value of TA or RTT inherent to the satellite system is 5ms (i.e. the second offset value), the beam scanning pattern is the same as that in embodiments 1 and 2 described above, and the uplink transmission timeslot is determined by using (n + the number of timeslots corresponding to the second offset value + k 1) or (n + the number of timeslots corresponding to the second offset value), and assuming that the value of k1 is relatively small and is not enough to exceed the offset of 1ms, then for UE1, in a beam scanning cycle, in a time period in which 10ms serves UE1, the uplink transmission timeslot determined in the above manner in the first 5ms of downlink transmission is in the time period in which the current cycle serves the terminal (i.e. the last 5ms of 10 ms), that is, in the downlink transmission in this part of time, the uplink transmission timeslot can be determined based on the second offset value =5ms, and the 10ms serves the time period of UE1, the time slots in which the uplink transmission in the last 5ms is determined in the above manner are all time slots in which the uplink transmission is not served by the terminal in the current period (in the time slot served by the UE 2), transmission is required in the next period, at this time, if one period (20 ms) is directly used as an offset value to determine the time slot in which the uplink transmission is located, the downlink transmission in the last 5ms of the 10ms serving the UE1 in the previous period schedules the uplink transmission to also occur in the last 5ms of the 10ms serving the UE1 in the next period, and the downlink transmission in the first 5ms of the 10ms serving the UE1 can be scheduled for uplink transmission in the last 5ms of the same period, which results in that there is no way for the uplink transmission to be scheduled in the first 5ms of the 10ms serving the UE1 in one period, therefore, at this time, it is reasonable that the downlink transmission in the last 5ms of the 10ms serving the UE1 is defined as an offset according to the time period not serving the terminal in one beam cycle, that is, the offset value is 10ms, so that the uplink transmission in the first 5ms of the 10ms serving the UE1 in the next cycle can be scheduled. Then, 2 first offset values may be configured to the terminal, where the first offset value may be 5ms (that is, the size of the second offset value), and is used for providing downlink transmission in the first 5ms of 10ms serving the UE1 in one cycle to determine that corresponding uplink transmission is performed in the last 5ms of 10ms serving the UE1 in the same cycle, and the second first offset value may be 10ms, and is used for providing downlink transmission in the last 5ms of 10ms serving the UE1 in one cycle to determine that corresponding uplink transmission is performed in the first 5ms of 10ms serving the UE1 in the next cycle, as shown in fig. 11, where, for example, a specific position offset where k1 does not exist and only affects a time slot is included, and the scheme is similar and is not described again. Specifically, how to select one of the two first offset values as a target first offset value to determine a timeslot for uplink transmission may refer to the method in embodiment 2, as follows:

Mode 1: the indication in DCI dynamically indicates the way in which one of the values is used by the terminal to inform that for a certain time slot n, according to the formula

Or

Calculating which K to use when transmitting the slot of HARQ-ACK _offset A value; for example, a first value (5 ms) may be indicated for the case where the PDSCH or the PDCCH requiring feedback of HARQ-ACK is transmitted in a slot n in the first 5ms in the UE1 service period in the first cycle, and a second value (10 ms) may be indicated for the case where the PDSCH or the PDCCH requiring feedback of HARQ-ACK is transmitted in a slot n in the last 5ms in the UE1 service period in the first cycle; correspondingly, the terminal obtains the first offset value from the received DCI according to the corresponding method, so as to calculate and obtain the time slot for transmitting the HARQ-ACK according to the same method;

mode 2: pre-configuring a corresponding relationship, for example, dividing the first 5ms of 10ms of a service terminal 1 in a period into a time period (first time period), dividing the last 5ms into a time period (second time period), respectively agreeing or configuring corresponding first offset values for the first time period and the second time period to be 5ms and 10ms, respectively, so that both the network device and the terminal can determine which first offset value to use according to the actual time slot position of receiving the PDSCH or the PDCCH that needs to perform HARQ-ACK feedback, thereby obtaining a corresponding HARQ-ACK transmission time slot;

Mode 3: the network device and the terminal may determine which first offset value to select according to whether the obtained time slot (the number of time slots corresponding to the (n + second offset value)) or the obtained time slot (the number of time slots corresponding to the (n + second offset value) + the number of time slots corresponding to the k 1) is within the time period of the beam serving the terminal; then, for the time slot in the first 5ms of the 10ms period in one cycle serving the terminal 1, it is determined that the target time slot calculated in the above-described manner is within the service period, and it is determined to use the first value (5 ms), and for the time slot in the last 5ms of the 10ms period in one cycle serving the terminal 1, it is determined that the target time slot calculated in the above-described manner is not within the service period, and it is determined to use the second value (10 ms).

In the above embodiment, if the configured multiple first offset values include the second offset value, the second offset value may be 1 value directly configured by the RRC, or the RRC configures multiple candidate values in advance, and a suitable value is selected from the specific positions of the satellite and the terminal as the propagation delay compensation value between the satellite and the ground, specifically, the second offset value may be obtained in a DCI notification manner, a MAC CE notification manner, or the like, where the DCI or the MAC CE may directly notify a second offset value, or notify a deviation between the second offset value and a known second offset value, so as to form a new second offset value. The second offset value involved in the selection from the plurality of first offset values may be a new second offset value updated based on the above-mentioned manner.

It should be noted that, in order to transmit the HARQ-ACK feedback through the PUCCH, when the PDCCH is substituted for scheduling PUSCH transmission, the above method is also applicable, but only the value of k1 is adjusted to k2, and details are not described here.

It should be noted that, in the above embodiments, the uplink beam scanning pattern and the downlink beam scanning pattern are the same (that is, only one beam scanning pattern) as an example, and if the uplink beam scanning pattern and the downlink beam scanning pattern are different, in the above embodiments, when the first offset value is configured, the offset value of the service time of the uplink beam and the downlink beam serving the terminal or the beam position needs to be further considered to compensate for the offset caused by the misalignment of the uplink beam and the downlink beam.

For the above method and embodiment, if the uplink and downlink have different beam scanning patterns and/or periods, it is determined whether to be in the service time period serving the current terminal or wave position, specifically, whether to be in the service time period serving the current terminal or wave position determined according to the uplink beam scanning patterns and periods; the period of the beam scanning is specifically a scanning period of the uplink beam.
