As an example, the Terminal device may include a Mobile handset, a station, a unit, a device, a Mobile Terminal (MT), a subscription station, a portable subscription station, an Internet node, a communicator, a desktop computer, a laptop computer, a notebook computer, a tablet computer, a Personal communication system device, a Personal navigation device, a Personal Digital Assistant (PDA), a positioning device, a radio broadcast receiver, an electronic book device, a gaming device, an Internet of Things (IoT) device, a vehicle device, an aircraft, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wearable device, a Terminal device in a 5G Network or any Terminal device in an evolved Public Land Mobile Network (PLMN), other devices that may be used for communication, or any combination thereof. The embodiments of the present disclosure do not limit this.

The term "access network device" as used in this disclosure is an entity or node that may be used to communicate with a terminal device. The Access Network device may be a device deployed in a Radio Access Network (RAN) to provide a Radio communication function for the mobile terminal, for example, a Radio Access Network (RAN) Network device. The access network equipment may include various types of base stations. By way of example, an access network device may include various forms of macro base stations, micro base stations, pico base stations, femto base stations, relay stations, access points, remote Radio Units (RRUs), radio Heads (RH), remote Radio Heads (RRHs), and so forth. In systems using different radio access technologies, names of access network devices may be different, for example, referred to as evolved node bs (evolved NodeB, eNB or eNodeB) in a Long Term Evolution (LTE) system, referred to as node bs (NodeB, NB) in a 3G network, referred to as G node bs (gNB) or NR node bs (NR NB) in a 5G network, and so on. In some scenarios, an access network device may include a Central Unit (CU) and/or a Distributed Unit (DU). CUs and DUs can be placed in different places, for example: and the DU is pulled away and is placed in an area with high telephone traffic, and the CU is placed in a central computer room. Alternatively, CU and DU may be located in the same room. CU and DU can also be different components under one chassis. For convenience of description, in the embodiments subsequent to the present disclosure, the above-mentioned apparatus for providing a mobile terminal with a wireless communication function is collectively referred to as an access network device, and the embodiments of the present disclosure are not limited in detail.

The term "Joint Channel Estimation (JCE)" used in the present disclosure may be used to implement Coverage Enhancement (CE). The joint Channel estimation may be used between Physical Downlink Shared channels (PUSCHs), or may be used between Physical Uplink Control Channels (PUCCHs), or may be used between the PUSCHs and the PUCCHs, or may be used between other Uplink transmissions. Joint channel estimation may be used between one scheduling or repetitions of different schedules, or between different schedules. Joint channel estimation may be performed over a Time Domain Window (TW) spanning several Time slots or symbols, and is performed on the condition that the continuity of phase and consistency of transmission power need to be maintained. The joint Channel Estimation may also be referred to as "Cross-Slot Channel Estimation" or "Demodulation Reference Signal bundling (DMRS bundling)" or the like. For convenience of description, in the following embodiments of the present disclosure, explanation is made based on "joint channel estimation".

The term "slot" as used in this disclosure is a unit of time for which data is scheduled. There are various scheduling time units, e.g., frames (frames), subframes (subframes), slots and symbols (symbols), etc., in a wireless communication system, such as 5 GNR. Generally, a time length of a frame is 10ms, and the frame includes 10 subframes, and each subframe corresponds to a time length of 1ms. Each subframe consists of several slots. Under a normal cyclic prefix, one slot includes 14 symbols; under the extended cyclic prefix, one slot includes 12 symbols. The symbols may be Orthogonal Frequency Division Multiplexing (OFDM) symbols. It should be noted that the slot in the embodiment of the present disclosure may be a slot including 14 symbols, and may also be a mini-slot (mini-slot), which is not particularly distinguished hereinafter.

The term "repetition" used in the present disclosure may be the number of times that the transmission is repeated upon PUSCH and/or PUCCH transmission. The repetition may be a repetition factor, a repetition number, a number of repeated transmission slots, and the like, and is configured by Radio Resource Control (RRC) or Downlink Control Information (DCI). For PUSCH, there are two repetition types: a repetition type a (repetition type a) and a repetition type B (repetition type B). The repetition type a is a method in which a repetition is transmitted once in each slot, and each slot occupies consecutive symbols having the same position and number, and in the repetition type a, a repetition factor of RRC or DCI configuration is equal to the number of repetitions and also to the number of repeated transmission slots. In repetition type B, the repetition factor of the RRC or DCI configuration refers to the number of nominal repetitions (nominal repetition), each nominal repetition is allocated the same number of symbols, and the time domain resources of adjacent nominal repetitions are consecutive, and the nominal repetition may also be referred to as nominal repetition. Since the transmission of repetition type B cannot use invalid symbols (invalid symbols) and cannot cross slot boundaries (slot boundaries), nominal repetition of repetition type B needs to be sliced into actual repetitions around the invalid symbols or slot boundaries when encountering the invalid symbols or slot boundaries. For PUCCH, there is a repetition type, and repetition of PUCCH is similar to repetition type a of PUSCH.

The term "Transmission Opportunity (TO)" used in the present disclosure is a representation on a time domain. For PUSCH repetition type a or for PUCCH repetition, TO may be a time domain resource occupied by one repetition, e.g., one slot. For PUSCH repetition type B, TO may be a time domain resource occupied by one actual repetition, or may be one slot.

In the current wireless communication system, the terminal device needs to determine the transmission power before performing uplink transmission. However, in the current scheme, factors such as joint channel estimation and the like are not considered when the terminal device determines the transmission power, so that the determined transmission power has low accuracy and the efficiency of uplink transmission is affected.

Embodiments of the present disclosure provide a transmission scheme. According to the scheme, the terminal equipment can determine the transmitting power based on the time domain window, so that the determined transmitting power is more accurate, and the efficiency of uplink transmission is ensured. Embodiments according to the present disclosure are described in more detail below by means of fig. 1 to8.

Fig. 1 illustrates a schematic diagram of a communication system 100 in which embodiments of the present disclosure may be implemented. As shown in fig. 1, the system 100 includes an access network device 110 and a terminal device 120, and communication can be performed between the access network device 110 and the terminal device 120.

Access network device 110 may configure higher layer signaling to terminal device 120, where the higher layer signaling refers to signaling sent by a higher layer protocol layer, and the higher layer protocol layer is at least one protocol layer above a physical layer. Illustratively, the higher layer protocol layers may include at least one of the following protocol layers: a Medium Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Resource Control (RRC) layer, and a Non-Access Stratum (NAS) layer.

Fig. 2 shows a schematic flow diagram of a transmission method 200 according to an embodiment of the present disclosure. As an example, method 200 may be implemented at terminal device 120 shown in fig. 1. For ease of understanding, the transmission method 200 is described below by taking the terminal device 120 as an example, but this is merely exemplary and is not intended to limit the embodiments of the present disclosure in any way.

The method 200 begins at block 210. At 210, the terminal device 120 determines a power control adjustment value (power control adjustment state) at the current transmission opportunity based on a time domain window prior to the current transmission opportunity, wherein the time domain window includes at least two transmission opportunities.

It can be appreciated that the current transmission opportunity is a transmission opportunity for which power control is required to re-determine the transmit power. In general, a time domain window may cover at least two transmission occasions, and power control is required at a starting transmission occasion of the time domain window.

In this embodiment of the present disclosure, at least two transmission occasions within the time domain window may have the same transmission characteristic information, where the same transmission characteristic information includes at least one of the following: the same Transmitted Precoding Matrix Indicator (TPMI) precoder, the same transmit power, the same frequency domain Resource occupancy (e.g., physical Resource Block (PRB)), phase continuity, the same antenna port, and the like.

For example, at least two transmission occasions within a time domain window have the same transmit power meaning that: no power control or power adjustment is performed at the non-initial transmission occasions of the time domain window, so that the transmission power of each transmission occasion in the time domain window can be equal.

In the embodiments of the present disclosure, the time domain window may be used for joint channel estimation, or may be used for other scenarios in which the transmit power is constant within the time domain window. In the embodiments of the present disclosure, the time domain window may also be referred to as a time window, a joint transmission opportunity, an invariant transmission opportunity, or the like. In the embodiment of the present disclosure, the power control adjustment value may also be referred to as a power control adjustment state value, a power control adjustment state parameter, a power control adjustment state item, a power control adjustment state, a power control adjustment parameter, or the like, which is not limited in the present disclosure.

Fig. 3 shows a time domain diagram 300 for terminal device transmission in accordance with an embodiment of the disclosure. In fig. 3, a time domain window 310 is shown and includes 4 TOs, TO1 TO4 respectively. It can be appreciated that the starting transmission opportunity for the time domain window 310 is TO1 301, and the current transmission opportunity after the time domain window 310 is TO5 302. That is, the starting transmission opportunity 301 is the first TO within the time domain window 310, and the current transmission opportunity 302 is the first TO after the time domain window 310.

In some examples, the current transmission opportunity may be a starting transmission opportunity of another time domain window after the time domain window. As shown in fig. 3, time domain window 310 is followed by time domain window 320, and time domain window 320 includes 4 TOs, respectively TO5 TO8. The current transmission opportunity TO5 follows the time domain window 310, and the current transmission opportunity TO5 is the starting transmission opportunity of the time domain window 320.

It is appreciated that in some embodiments, one TO may correspond TO one slot, for example in the context of PUSCH repetition type a.

Fig. 4 shows another time domain diagram 400 for terminal device transmission in accordance with an embodiment of the disclosure. In fig. 4, a time domain window 410 is shown and includes 4 TOs, respectively TO1 TO4. It can be appreciated that the starting transmission opportunity for the time domain window 410 is TO1 and the current transmission opportunity after the time domain window 410 is TO5. In addition, as shown in fig. 4, there is also an interrupt time domain resource 420 after the time domain window 410 and before the current transmission opportunity TO5.

In some examples, the length of the interrupt time domain resource 420 may be 1 or more slots, or may be 1 or more symbols, and so on. In one scenario, if there is a period of time after the time domain window 410 during which no uplink transmission is required, the period of time constitutes an interrupted time domain resource 420, that is, the interrupted time domain resource 420 is not scheduled for transmission by the current terminal device. In another case, if an interruption is caused by some factor in the process of performing joint channel estimation, the interrupted time constitutes an interrupted time domain resource 420.

For example, for a configured nominal time domain window, the nominal time domain window may be interrupted due to some factors, so that one nominal time domain window is interrupted and divided into at least two actual time domain windows. Such factors include, but are not limited to: a dynamic Slot Format Indication (SFI), an uplink cancellation Indication (UL CI), channel preemption of different priorities, timing adjustment (such as Timing Advance command (TA command) or time Advance change (TA change)), frequency offset correction, carrier Aggregation (CA), dual-Connectivity (DC), etc.

It should be noted that although the nominal and actual time domain windows are referred to in this disclosure, the distinction between nominal and actual time domain windows is intended to introduce an interruption time domain resource. Both the nominal time domain window and the actual time domain window may be time domain windows used for joint channel estimation.

Fig. 5 shows yet another time domain diagram 500 for terminal device transmission according to an embodiment of the present disclosure. In fig. 5, the nominal time domain window 510 is broken into an actual time domain window 511 and an actual time domain window 512, and between the actual time domain window 511 and the actual time domain window 512 is an interrupted time domain resource 520.

For the time domain window 511, its starting transmission opportunity is shown in fig. 5 as starting transmission opportunity 501, and the current transmission opportunity after the time domain window 511 is shown in fig. 5 as current transmission opportunity 502. It can be seen that between the starting transmission occasion 501 and the current transmission occasion 502, in addition to the time domain window 511, also an interrupted time domain resource 520 is included which is not used for joint channel estimation.

In the disclosed embodiment, the time domain window at 210 may refer to an actual time domain window. It is understood that the current transmission opportunity in the embodiments of the present disclosure may be the starting transmission opportunity of the next time domain window of the time domain window in 210, or may be other transmission opportunities other than the time domain window. And it should be understood that although the time domain window in 210 includes at least two transmission occasions, the next time domain window located after the time domain window may include one or more transmission occasions. For example, in fig. 3, the time domain window in which the current transmission opportunity is located includes 4 transmission opportunities. For another example, in fig. 5, the time domain window in which the current transmission opportunity is located includes 1 transmission opportunity. In other words, the applicable scenarios of the embodiments of the present disclosure may be: the power of the previous transmission opportunity (or the last transmission opportunity) of the current transmission opportunity is not changed, for example, no power update is performed or no calculation or re-determination of the power update is performed. More specifically, as an example, in a scenario where joint channel estimation is performed, a transmission opportunity that is prior to a current transmission opportunity belongs to a non-initial transmission opportunity of a time domain window for joint channel estimation.

In one implementation, the transmission to be made by the terminal device 120 is a PUSCH, and the power control adjustment value determined at 210 is a PUSCH power control adjustment value.

For the following description, it is assumed that the terminal apparatus 120 performs PUSCH transmission on a carrier f of an active Uplink Bandwidth Part (active UL BWP) b of the serving cell c, and expresses a PUSCH power control adjustment value of state i at a transmission timing i as f _b,f,c (i,l)。

In some embodiments, if terminal device 120 is not configured with a Transmit Power Control (TPC) Accumulation (TPC-Accumulation) parameter, then at 210, terminal device 120 may determine a Power Control adjustment value at the current Transmission opportunity based on an initial Power Control adjustment value for a starting Transmission opportunity of a time domain window and an Accumulation, wherein the Accumulation is an Accumulation of a first parameter value in all DCI received between a first time associated with the starting Transmission opportunity to a second time associated with the current Transmission opportunity.

Specifically, the terminal device 120 may obtain an initial power control adjustment value of the initial transmission opportunity of the time domain window; determining an accumulation of first parameter values in all DCI received between a first time associated with a starting transmission opportunity to a second time associated with a current transmission opportunity; a power control adjustment value for the current transmission opportunity is determined based on the initial power control adjustment value and the accumulation.

In the embodiment of the present disclosure, the TPC accumulation parameter may be configured or provided through higher layer signaling, and when the terminal device 120 is not provided with the TPC accumulation parameter, the power control adjustment value at the current transmission opportunity may be determined based on the initial power control adjustment value of the initial transmission opportunity.

Illustratively, the initial power control adjustment value for the starting transmission occasion of the time domain window may be expressed as f _b,f,c (i-i ₀ L), which may be determined when determining the transmit power of the starting transmission opportunity.

Illustratively, the first parameter value may be a TPC accumulated value corresponding to a TPC command field (TPC command field) parameter in the DCI, specifically, a TPC accumulated value for the PUSCH. In some examples, the first parameter value may be indicated by a TPC command field in a DCI format that schedules the PUSCH transmission, as shown in table 1 below. In other examples, the first parameter value may be indicated by a DCI format 2 \u2 scrambled by a transmission power control-physical uplink shared channel-radio network temporary identity (TPC-PUSCH-RNTI) through a Cyclic Redundancy Check (CRC).

TABLE 1

Exemplarily, the first parameter value for PUSCH may be denoted as δ _{PUSCH，b,f,c,} (, l), thereby representing the accumulation of the first parameter value in all DCI received between a first time associated with the starting transmission opportunity to a second time associated with the current transmission opportunity as

Set of representations D _i Sum of the accumulated values of TPCs in (1), wherein the set D _i Is determined based on the first time and the second time.

The first time associated with the starting transmission opportunity may be the first S1 th symbol of the starting transmission opportunity. That is, the first time is before the initial transmission timing, and the first time and the initial transmission timing may be separated by S1 symbols. In other words, the first time is located at the S1 th symbol before the initial transmission opportunity. For example, the first time may be the initial transmission opportunity i-i ₀ First K of _PUSCH (i-i ₀ ) 1 symbol, i.e. S1= K _PUSCH (i-i ₀ )-1。

The second time instance associated with the current transmission opportunity may be the S2 th symbol prior to the current transmission opportunity. That is, the second time is before the current transmission opportunity, and the second time and the current transmission opportunity may be separated by S2 symbols. In other words, the second time instant is located at the S2 th symbol before the current transmission opportunity. For example, the second time may be the first K of the current transmission opportunity i _PUSCH (i) One symbol, i.e. S2= K _PUSCH (i)。

Understandably, i ₀ > 0, and i ₀ Is to make PUSCH transmission opportunity i-i ₀ First K of _PUSCH (i-i ₀ ) -1 symbol earlier than the first K of PUSCH transmission opportunity i _PUSCH (i) A minimum integer number before a symbol, and i-i ₀ Is the first transmission opportunity of the time domain window, also referred to as the starting transmission opportunity.

In some examples, K may be determined in the following manner _PUSCH (i) In that respect If the PUSCH transmission is scheduled by DCI, then K _PUSCH (i) Is the number of symbols from the last symbol of the Physical Downlink Control Channel (PDCCH) corresponding to the DCI to the first symbol of the scheduled PUSCH transmission.

In other examples, K may be determined in the following manner _PUSCH (i) .1. The If the PUSCH transmission is configured by RRC, e.g., by a "configured grant configuration (ConfiguredGrantConfig)", etc., then K _PUSCH (i) Is K _PUSCH，min Number of symbols, which may be equal to the number of symbols per slot

(e.g., 12 or 14) and the minimum value indicated by the k2 field in the PUSCH-configured common field (PUSCH-ConfigCommon).

Understandably, determining K _PUSCH (i-i ₀ ) Manner of-1 and determination of K _PUSCH (i) The manner of (c) is similar and therefore not repeated here.

In an embodiment of the disclosure, the accumulation of the first parameter values is an accumulation of all first parameter values between the first time instant and the second time instant. The accumulation may be determined once, or may be determined separately for each transmission opportunity and then accumulated.

Fig. 6 shows a time domain diagram 600 for transmission of PUSCH according to an embodiment of the present disclosure. In fig. 6, the scheduled PUSCH of DCI 0\ u x contains 8 repeated transmissions, where each slot is one transmission opportunity, TO1 TO8, respectively. Two time domain windows, time domain window 601 and time domain window 602, are shown in fig. 6, where each time domain window contains 4 TOs. In addition, a first time instant associated with the starting transmission occasion TO1 of the time domain window 601 is shown in fig. 6 as a first time instant 610, in particular, shown as the kth symbol before the starting transmission occasion TO 1. The second time instant associated with the current transmission occasion TO5 after the time domain window 601 is shown in fig. 6 as second time instant 620, in particular, shown at the kth symbol before the current transmission occasion TO5. The accumulation of the first parameter value from the first time to the second time may be once, as shown by Σ δ in fig. 6.

Fig. 7 shows another time domain diagram 700 for transmission of PUSCH according to an embodiment of the present disclosure. Similar TO fig. 6, two time domain windows, time domain window 701 and time domain window 702, are shown in fig. 7, where each time domain window contains 4 TOs. In addition, a first time instant associated with the starting transmission occasion TO1 of the time domain window 701 is shown in fig. 7 as first time instant 710, and a second time instant associated with the current transmission occasion TO5 after the time domain window 701 is shown in fig. 7 as second time instant 720. The accumulation of the first parameter values from the first time to the second time may be determined separately for each transmission occasion and then accumulated.

Specifically, in fig. 7, the time domain window 701 includes 4 transmission occasions, which are TO1 TO4 respectively. Then a first accumulation of the first parameter value between a first time instant associated with the transmission occasion TO1 TO a third time instant associated with the transmission occasion TO2, denoted as Σ δ 1, may be determined. A second accumulation of the first parameter value between the third time instance associated with the transmission occasion TO2 TO the fourth time instance associated with the transmission occasion TO3, denoted as Σ δ 2, may be determined. A third accumulation of the first parameter value between the fourth time instant associated with the transmission occasion TO3 TO the fifth time instant associated with the transmission occasion TO4, denoted as Σ δ 3, may be determined. A fourth accumulation of the first parameter value between the fifth time instance associated with the transmission occasion TO4 TO the second time instance associated with the transmission occasion TO5 may be determined, denoted as Σ δ 4. Further, based on the first accumulation, the second accumulation, the third accumulation and the fourth accumulation, the accumulation of the first parameter value from the first time to the second time is obtained, and is expressed as Σ δ =Σδ 1+ ∑ δ 2+ Σδ 3+ Σδ 4.

For non-initial transmission occasions within the time domain window, the transmit power of the non-initial transmission occasions are not updated in order to maintain power consistency (i.e., transmit power is not changed) within the time domain window. At such non-initial transmission occasions, the power control adjustment value at the non-initial transmission occasions may be updated, but the updated power control adjustment value is not used to determine the transmit power at the non-initial transmission occasions.

Referring TO fig. 7, assuming that the initial power control adjustment value of the starting transmission occasion TO1 of the time domain window 701 is denoted as f1, the power control adjustment value at the transmission occasion TO2 may be determined based on f1 and the first accumulation Σ δ 1, denoted as f2. Similarly, a power control adjustment value at transmission opportunity TO3, denoted as f3, may be determined based on f2 and the second accumulation Σ δ 2. A power control adjustment value at transmission opportunity TO4, denoted as f4, may be determined based on f3 and the third accumulation Σ δ 3. In this way, even for non-initial transmission occasions of the time domain window 701, the corresponding power control adjustment value is determined. It should be noted that although the power control adjustment values at the transmission occasions TO2, TO3 and TO4 are determined, the power consistency within the time domain window 701 can be ensured by performing the determination based on f1 when determining the transmission power at the transmission occasions TO2, TO3 and TO4.

Further, the way of determining the power control adjustment value of the current transmission timing TO5 may be: the power control adjustment value for the current transmission timing TO5, denoted as f5, is determined based on the power control adjustment value f4 for the transmission timing TO4 and the fourth accumulation Σ δ 4. It can be understood that, since the current transmission timing TO5 does not belong TO the same time domain window any more, the power update needs TO be performed at the current transmission timing TO5, and therefore, the transmission power at the current transmission timing TO5 is determined based on the updated power control adjustment value f5 instead of f1.

In this manner, an accumulation of the first parameter values in all DCI received between a first time associated with the starting transmission opportunity to a second time associated with the current transmission opportunity may be obtained. Further, in the embodiment of the present disclosure, the adjustment value f may be adjusted based on the initial power control _b，f，c (i-i ₀ L) and accumulation of the first parameter value in all DCI received between the first time and the second time

Determining the power of a current transmission opportunityRate control adjustment value f _b，f，c (i，l)。

Specifically, if (1) transmission timing i-i is initiated ₀ Is the maximum transmission power and

or (2) an initial transmission opportunity i-i ₀ Has a minimum transmission power and

then f _b，f，c (i，l)＝f _b，f，c (i-i ₀ L). Otherwise, taking the accumulated sum of the initial power control adjustment value and the first parameter value as the power control adjustment value of the current transmission opportunity, and expressing as:

in other embodiments, if terminal device 120 is configured with a transmit power control, TPC, accumulation (TPC-Accumulation) parameter, then at 210, terminal device 120 may determine a scaling factor based on the time domain window; acquiring a second parameter value corresponding to the TPC command field parameter in DCI from the access network equipment; a power control adjustment value at the current transmission opportunity is determined based on the second parameter value and the scaling factor.

In the embodiment of the present disclosure, the TPC accumulation parameter may be configured or provided through higher layer signaling, and when the terminal device 120 is provided with the TPC accumulation parameter, the power control adjustment value at the current transmission occasion may be determined based on the scaling factor and the second parameter value.

Exemplarily, the second parameter value may be a TPC absolute value corresponding to a TPC command field (TPC command field) parameter in the DCI. That is, the second parameter value may be indicated by a TPC command field in a DCI format that schedules the PUSCH transmission, as shown in table 2 below. Illustratively, canTo represent the second parameter value as delta' _PUSCH,b,f,c (i,l)。

The scaling factor may be determined based at least in part on a gap length, wherein the gap length is a total length between a starting transmission opportunity to a current transmission opportunity of a time domain window or a length of the time domain window.

Illustratively, the length in the embodiments of the present disclosure represents a time domain length, which may be at least one of: the number of slots, the number of symbols, the number of transmission opportunities, the number of repetitions, etc., wherein the number of repetitions may be a nominal number of repetitions or an actual number of repetitions, etc., and the disclosure is not limited thereto.

In some examples, a total length between a starting transmission opportunity to a current transmission opportunity of the time domain window may be equal to a length of the time domain window. Optionally, in a case that the time domain resource is not included between the start transmission occasion and the current transmission occasion, a total length between the start transmission occasion and the current transmission occasion is equal to a length of the time domain window. Referring TO fig. 3, the total length or length is equal TO4 time slots or 4 TOs.

In other examples, a total length between the starting transmission opportunity to the current transmission opportunity of the time domain window may not be equal to the length of the time domain window. Optionally, in a case where an interrupted time domain resource not used for joint channel estimation is included between the starting transmission opportunity and the transmission opportunity, a total length between the starting transmission opportunity and the current transmission opportunity may not be equal to a length of the time domain window. Referring to fig. 5, the total length between the start transmission opportunity 501 and the current transmission opportunity 502 is 3 slots, and the length of the time domain window 511 between the start transmission opportunity 501 and the current transmission opportunity 502 is 2 slots.

In some examples, a total length between a starting transmission opportunity of the time domain window to a current transmission opportunity or a length of the time domain window may be taken as the interval length, and the interval length is taken as the scaling factor. Specifically, a dimensionless value after the interval length is dimensionless may be taken as the scale factor.

For example, referring to fig. 3, the total length between the starting transmission opportunity to the current transmission opportunity or the length of the time domain window is 4 slots, then the scaling factor may be equal to4. For another example, referring to fig. 5, if the total length from the start transmission opportunity to the current transmission opportunity is 3 slots, then the scaling factor may be equal to 3. By way of further example, referring to fig. 5, the time domain window is 2 slots long, and then the scaling factor may be equal to 2.

In other examples, the total length between the start transmission opportunity to the current transmission opportunity of the time domain window or the length of the time domain window may be taken as the interval length; and obtaining the scale factor corresponding to the interval length based on the corresponding relation between the interval length and the scale factor, wherein the corresponding relation is configured or predefined by the RRC of the access network equipment.

Illustratively, access network device 110 may configure the correspondence between the interval length and the scaling factor through RRC, and terminal device 120 may determine the scaling factor corresponding to the interval length based on the correspondence.

For example, the interval length and the scaling factor may have a one-to-one correspondence, for example, when the interval length is 3, the scaling factor is X1; the scale factor is X2 for a space length of 2. For another example, the interval length and the scaling factor may have a many-to-one correspondence, for example, when the interval length is 3 and 4, the scaling factor is X1; the scale factor is X2 for interval lengths of 1 and 2. For another example, the interval length and the scale factor may be interval-to-discrete value correspondence, for example, interval length interval (0, 2) corresponds to scale factor x1.

In other examples, a total length between a starting transmission opportunity of the time domain window to the current transmission opportunity or a length of the time domain window may be taken as an interval length, a scaling factor in RRC signaling or DCI from the access network device or predefined may be obtained, and the scaling factor may be determined based on the interval length and the scaling factor.

Illustratively, access network device 110 may configure one scaling factor through RRC or through DCI. Alternatively, access network device 110 may configure the multiple scaling factors by RRC, with one of the multiple scaling factors being indicated by DCI or MAC-CE. Illustratively, the product of the interval length and the scaling factor may be used as the scaling factor. Specifically, the product of the dimensionless value of the interval length after dimensioning and the scaling factor may be used as the scaling factor.

In this way, the scaling factor may be determined based on the interval length in the above manner, and further, the power control adjustment value at the current transmission occasion may be determined based on the scaling factor and the second parameter value. Illustratively, the product of the second parameter value and the scaling factor may be used as the power control adjustment value at the current transmission opportunity.

In particular, by expressing the scale factor as β, then one can pass f _b,f,c (i,l)＝β×δ′ _PUSCH,b,f,c (i, l) obtaining a power control adjustment value at the current transmission opportunity.

In the embodiments of the present disclosure, the scaling factor may also be referred to as an adjustment factor or a power control adjustment factor or other names, and the scaling factor may be used to adjust the TPC command adjustment value to determine the power control adjustment value.

In this way, in the embodiment of the present disclosure, the power control adjustment value of the current transmission opportunity is determined based on both the scaling factor and the second parameter value, and thus the actually required amplitude of power adjustment can be better adapted, where the scaling factor is determined based on the interval length, and the time domain span between two times of power control is considered, thereby ensuring the communication performance.

In other embodiments, if the terminal device 120 is configured with a transmit power control, TPC, accumulation (TPC-Accumulation) parameter, then at 210, the terminal device 120 may obtain an interval length, where the interval length is a total length between a start transmission opportunity of a time domain window and a current transmission opportunity or a length of the time domain window; obtaining TPC command field parameters in DCI from access network equipment; a power control adjustment value at the current transmission opportunity is determined based on the interval length and the TPC command field parameters.

With regard to the interval length, reference may be made to the description in relation to the above embodiments, which will not be repeated here for the sake of brevity.

In some examples, the TPC command field may occupy 2 bits, and accordingly, the TPC command field parameter is any one of values 0 to 3. In other examples, the TPC command field may occupy 3 bits, and accordingly, the TPC command field parameter is any one of values 0 to 7.

For example, determining a power control adjustment value at the current transmission opportunity based on the interval length and the TPC command field parameters may include: and determining a TPC absolute value corresponding to the interval length and the TPC command field parameter, and taking the TPC absolute value as a power control adjustment value of the current transmission opportunity.

As an example, as shown in table 3, a row of the TPC absolute value may be determined based on the TPC command field parameter, and a column of the TPC absolute value may be determined based on the gap length, so that the TPC absolute value can be determined based on both the TPC command field parameter and the gap length.

In the embodiment of the present disclosure, different TPC absolute values may be applicable for different gap lengths. For example, in Table 3, when the interval length is 3, the corresponding TPC absolute values are-8, -2, 8. When the interval length is 2, the corresponding TPC absolute value is-6, -1, 6.

TABLE 3

It should be noted that table 3 is merely illustrative, and that a certain column of absolute values of TPC may correspond to one or more interval lengths, e.g., interval lengths of 3 or 4 both correspond to column 2 of table 3, and interval lengths of 1 or 2 both correspond to column 3 of table 3; alternatively, a certain column of TPC absolute values may correspond to intervals of interval length, e.g., interval length in interval (2, 4) for column 2 of Table 3 and interval length in interval (0, 2) for column 3 of Table 3.

Therefore, in the embodiment of the present disclosure, the power control adjustment value of the current transmission opportunity is determined based on the interval length and the like, which can better adapt to the actually required power adjustment amplitude, and the time domain span between two times of power control is considered, thereby ensuring the communication performance. And optionally allows for extension of the TPC command field with some flexibility.

In another implementation, the uplink transmission to be made by terminal device 120 is PUCCH, and the power control adjustment value determined at 210 is a PUCCH power control adjustment value.

For the following description, it is assumed that terminal device 120 performs PUCCH transmission on carrier f of active Uplink Bandwidth Part (active UL BWP) b of serving cell c and expresses PUCCH power control adjustment value of l at transmission timing i as g _b,f,c (i,l)。

Specifically, at 210, terminal device 120 may determine a power control adjustment value at the current transmission opportunity based on an initial power control adjustment value for a starting transmission opportunity of a time domain window and an accumulation, where the accumulation is an accumulation of first parameter values in all DCI received between a first time associated with the starting transmission opportunity to a second time associated with the current transmission opportunity.

Illustratively, the initial power control adjustment value for the starting transmission occasion of the time domain window may be represented as g _b,f,c (i-i ₀ L), which may be determined when determining the transmit power of the starting transmission opportunity.

Exemplarily, the first parameter value may be a TPC accumulation value corresponding to a TPC command field (TPC command field) parameter in the DCI, specifically, the TPC accumulation value for the PUCCH. In some examples, the first parameter value may be indicated by a TPC command field in a DCI format scheduling a Physical Downlink Shared Channel (PDSCH) transmission corresponding to the PUCCH, as shown in table 4 below. In other examples, the first parameter value may be indicated by a DCI format 22 scrambled by a transmission power control-physical uplink shared channel-radio network temporary identity (TPC-PUSCH-RNTI) through a Cyclic Redundancy Check (CRC).

TABLE 4

TPC command field	TPC accumulated value [ dB ] of PUCCH]
		0	-1
1	0
		2	1
3	3

Exemplarily, the first parameter value for PUCCH may be represented as δ _{PUCCH，b，f，c} (m, l), further representing an accumulation of first parameter values in all DCI received between a first time associated with the starting transmission opportunity to a second time associated with the current transmission opportunity as

Representation set C _i Sum of accumulated values of TPC in (1), wherein set C _i Is determined based on the first time and the second time.

The first time associated with the starting transmission opportunity may be the first S11 th symbol of the starting transmission opportunity. That is, the first time is before the initial transmission timing, and the first time and the initial transmission timing may be separated by S11 symbols. In other words, the first time is located at the S11 th symbol before the initial transmission opportunity. For example, the first time may be the initial transmission opportunity i-i ₀ First K of _PUCCH (i-i ₀ ) 1 symbol, i.e. S11= K _PUCCH (i-i ₀ )-1。

The second time instance associated with the current transmission opportunity may be the S12 th symbol prior to the current transmission opportunity. That is to say thatThe second time is located before the current transmission opportunity, and the second time and the current transmission opportunity may be separated by S12 symbols. In other words, the second time instant is located at the S12 th symbol before the current transmission opportunity. For example, the second time instant may be the first K of the current transmission opportunity i _PUCCH (i) One symbol, i.e. S12= K _PUCCH (i)。

Understandably, i ₀ > 0, and i ₀ Is to make the PUCCH transmission opportunity i-i ₀ First K of _PUCCH (i-i ₀ ) -1 symbol earlier than the first K of PUCCH transmission opportunity i _PUCCH (i) A minimum integer number one symbol ago, and i-i ₀ Is the first transmission opportunity of the time domain window, which may also be referred to as the starting transmission opportunity of the time domain window.

In some examples, K may be determined in the following manner _PUCCH (i) In that respect K if the PUCCH transmission is in response to the detected DCI format _PUCCH (i) Is the number of symbols from the last symbol of the PDCCH corresponding to the DCI to the first symbol of the corresponding PUCCH transmission.

In other examples, K may be determined in the following manner _PUCCH (i) In that respect K if the PUCCH transmission is not in response to the detected DCI format _PUCCH (i) Is K _PUCCH，min Number of symbols, which may be equal to the number of symbols per slot

Understandably, determine K _PUCCH (i-i ₀ ) Manner of-1 and determination of K _PUCCH (i) The manner of (c) is similar and therefore not repeated here.

In an embodiment of the disclosure, the accumulation of the first parameter values is an accumulation of all first parameter values between the first time instant and the second time instant. The accumulation may be determined once, or may be determined separately for each transmission opportunity and then accumulated. This process is similar to the description for PUSCH above in connection with fig. 6 and 7, and is not repeated here for brevity.

In this manner, an accumulation of first parameter values in all DCI received between a first time associated with a starting transmission opportunity to a second time associated with a current transmission opportunity may be obtained. Further, in the embodiment of the present disclosure, the adjustment value f may be adjusted based on the initial power control _b，f，c (i-i ₀ L) and accumulation of the first parameter value in all DCI received between the first time and the second time

Determining a power control adjustment value f for a current transmission opportunity _b，f，c (i，l)。

Specifically, if (1) transmission opportunity i-i is initiated ₀ Is the maximum transmission power and

then g _b，f，c (i，l)＝g _b，f，c (i-i ₀ L). Otherwise, the accumulated sum of the initial power control adjustment value and the first parameter value is used as the power control adjustment value of the current transmission opportunity, and is represented as follows:

therefore, in the embodiment of the present disclosure, when the power control adjustment value of the current transmission opportunity is determined, the adjustment of the TPC command on the power control can be truly reflected, the transmission power control command value accumulated in the TPC cannot be omitted due to the limitation of the joint channel estimation on the power, the actual adjustment range can be better adapted, and the communication performance is ensured.

At 220, the terminal device 120 determines a transmit power at the current transmission opportunity based on the power control adjustment value at the current transmission opportunity.

In one implementation, the uplink transmission to be made by the terminal device 120 is a PUSCH, and the power control adjustment value determined at 210 is a PUSCH power control adjustment value, then accordingly, at 220, a PUSCH transmit power may be determined.

Illustratively, if the terminal device 120 performs PUSCH transmission on carrier f of active Uplink Bandwidth Part (active UL BWP) b of serving cell c, using parameter set configuration with index j, for PUSCH power control adjustment value f with state l _b，f，c (i, l), the transmission power of the PUSCH transmission occasion i is denoted P _{PUSCH，b，fc} (i，j，q _d L), can be determined according to the following formula:

in the above formula, P _CMAX，f，c (i) The maximum transmit power (maximum output power) for the PUSCH transmission opportunity i on carrier f of serving cell c is pre-configured. Min indicates that the value of the transmission power is the smaller of the upper and lower lines in the parenthesis. P _{O_PUSCH，b，f，c} (j) Is nominal power P _{O_NOMINAL_PUSCH，f，c} (j) And power budget compensation P _{O_UE_PUSCH，bf，c} (j) And may be configured by higher layers.

The bandwidth of PUSCH Resource allocation is represented by the number of Resource Blocks (RBs) used for PUSCH transmission timing. Alpha is alpha _b，f，c (j) Is a path loss compensation and can be configured by a higher layer. PL _b，f，c (qd) is the downlink path loss estimate (downlink path estimate) for active DL BWP estimated using the reference signal with index qd, and is in dB. Delta _{TF，b，f，c} (i) Is an adjustment value related to the number of Bits Per Resource Element (BPRE) transmitted.

In another implementation, the uplink transmission to be made by terminal device 120 is PUCCH, the determined power control adjustment value at 210 is a PUCCH power control adjustment value, and accordingly, at 220, PUCCH transmit power may be determined.

Illustratively, if the terminal device 120 performs PUCCH transmission on carrier f of active Uplink Bandwidth Part (active UL BWP) b of serving cell c, an index q is used _u For PUCCH power control adjustment value g of state l _b，f，c (i, l), the transmission power of PUCCH transmission occasion i is denoted as P _{PUCCH，b，f，c} (i，q _u ，q _d L), can be determined according to the following formula:

in the above formula, P _CMAX，f，c (i) The maximum transmit power of PUCCH transmission opportunity i on carrier f of serving cell c is pre-configured. P is _{O_PUCCH，b，f，c} (q _u ) Is nominal power P _{O_NOMINAL_PUCCH，f，c} (q _u ) And power budget compensation P _{O_UE_PUCCH，b，f，c} (q _u ) And may be configured by higher layers.

The bandwidth of PUCCH Resource allocation is represented by the number of Resource Blocks (RBs) used for PUCCH transmission timing. PL _b，f，c (qd) is the usage index q _d The downlink path loss estimate of active DL BWP estimated from the reference signal(s) in dB. Delta _{F_PUCCH} (F) Is an offset adjustment value, delta, respectively configured for different PUCCH formats _{TF，b，f，c} (i) Is an adjustment value related to the transmitted BPRE.

At 230, the terminal device 120 transmits at the transmit power at the current transmission opportunity.

Specifically, terminal device 120 may be designated as P _{PUSCH，b，fc} (i，j，q _d L) transmission of PUSCH, or, alternatively, with P _{PUCCH，b，fc} (i，q _u ，q _d And l) transmitting PUCCH.

Therefore, in the embodiment of the present disclosure, when determining the transmission power of the current transmission opportunity, a time domain window before the current transmission opportunity can be considered, so that the power state adjustment state can be more matched with a value to be adjusted at the opportunity, and the communication performance is ensured.

It is understood that the time domain window in the embodiments of the present disclosure may be used for joint channel estimation, and the joint channel estimation is not limited to between one scheduled PUSCH repetition or one scheduled PUCCH repetition, the joint channel estimation may be between different scheduled PUSCH repetitions, or may be between different scheduled PUCCH repetitions, or may be between PUSCH and PUCCH, or may be between message 3 repetitions (Msg 3 repetition) in a random access scenario, and the like, and the present disclosure is not limited thereto. Although the embodiments are described above for the PUSCH and PUCCH separately, the present disclosure may also include any combination of the above listed embodiments, may also include transmit power for other uplink transmissions, and so on, which are not listed in the present disclosure.

It is to be appreciated that although the above embodiments are described with respect to "time domain windows," the time domain windows may also be referred to as Joint Transmission Opportunities (JTOs), transmission opportunities for joint channel estimation (TOJ), and so on. For example, for a PUSCH repetition type a scenario or for a PUCCH repetition scenario, the joint transmission occasion corresponds TO a time domain window covering multiple TOs. For example, for the PUSCH repetition type B scenario, the joint transmission opportunity corresponds to an actual repetition, rather than a nominal repetition.

Accordingly, the process of determining a PUSCH power control adjustment value for a "Joint Transmission Opportunity (JTO)" may include: when not configured with a TPC accumulation parameter, determining a PUSCH power control adjustment value for a current joint transmission opportunity based on an initial PUSCH power control adjustment value for a previous joint transmission opportunity and an accumulation, wherein the accumulation is an accumulation of a first PUSCH parameter value in DCI from a first time associated with the previous joint transmission opportunity to a second time associated with the current joint transmission opportunity. Similarly, the process of determining a PUCCH power control adjustment value for "Joint Transmission Opportunity (JTO)" may include: determining a PUCCH power control adjustment value for a current joint transmission opportunity based on an initial PUCCH power control adjustment value for a previous joint transmission opportunity and an accumulation, wherein the accumulation is an accumulation of a first PUCCH parameter value in DCI from a first time associated with the previous joint transmission opportunity to a second time associated with the current joint transmission opportunity.

It is understood that, when determining the power control adjustment value for "Joint Transmission Opportunity (JTO)", the accumulation may be performed once or may be performed multiple times according TO, and no matter how the accumulation is determined, the manner of performing power control at the joint transmission opportunity may refer TO the existing manner. Therefore, the power control adjustment value meeting the actual requirement can be determined only by replacing the existing TO with JTO, so that the communication performance is ensured while the processing mode is simplified.

Fig. 8 shows another schematic flow diagram of a transmission method 800 according to an embodiment of the disclosure. As an example, method 800 may be implemented at terminal device 120 shown in fig. 1. For ease of understanding, the transmission method 800 is described below by taking the terminal device 120 as an example, but this is merely exemplary and is not intended to limit the embodiments of the disclosure in any way.

The method 800 begins at block 810. At 810, terminal device 120 obtains power indication information, where the power indication information is used to indicate a power adjustment value in a current time domain resource, the power indication information includes TPC indication information, and the current time domain resource includes at least two transmission occasions or a previous time domain resource of the current time domain resource includes at least two transmission occasions.

At 820, the terminal device 120 determines a power control adjustment value at the current time domain resource based on the power indication information.

At 830, the terminal device 120 determines a transmit power at the current time domain resource based on the power control adjustment value at the current time domain resource.

At 840, terminal device 120 transmits at the transmit power on the current time domain resource.

For example, time domain resources including at least two transmission occasions may be used for joint channel estimation, or may be used for other scenarios, etc., which are not limited by this disclosure. Illustratively, the time domain resources may be time domain windows, or may also be referred to as time windows, joint Transmission Opportunities (JTO), invariant transmission opportunities, transmission opportunities for joint channel estimation (TOJ), or others. For example, the power control adjustment value may also be referred to as a power control adjustment state or a power control adjustment state value or a power control adjustment state parameter or a power control adjustment state item or a power control adjustment parameter or the like, which is not limited in this disclosure.

In this embodiment of the present disclosure, at least two transmission occasions in the current time domain resource may have the same transmission characteristic information, where the same transmission characteristic information includes at least one of the following: the same TPMI, the same transmit power, the same frequency domain resource occupancy, phase continuity, the same antenna port, etc. Similarly, at least two transmission occasions within a previous time domain resource may have the same transmission characteristic information.

For example, at least two transmission occasions within the current time domain resource have the same transmit power meaning that: no power control/power adjustment is performed at the non-initial transmission occasions of the current time domain resources. Or it can be understood that the power control/power adjustment is performed at the first transmission occasion of the current time domain resource, and the transmit power of other transmission occasions after the first transmission occasion is equal to the transmit power of the first transmission occasion.

In one implementation, the method 800 shown in fig. 8 may be used to determine the PUSCH transmit power for the terminal device 120. Illustratively, without being configured with the TPC accumulation parameter, the PUSCH power control adjustment value at the current time domain resource is determined based on an initial power control adjustment value of a previous time domain resource of the current time domain resource and an accumulation, at 820, of the power adjustment values indicated by the power indication information in all DCI received between a first time instance associated with the previous time domain resource to a second time instance associated with the current time domain resource.

The power adjustment value indicated by the TPC indication information may be determined from a set of fetching values. As an example, the value set may be a TPC accumulated value, specifically, a TPC accumulated value of a PUSCH. For example, the TPC indication information may be a TPC command field parameter, and the power adjustment value indicated by the power indication information may be a TPC accumulated value of a PUSCH corresponding to the TPC command field parameter. For this embodiment, reference may be made to the description above in conjunction with table 1 and the like, and details are not repeated here for the sake of brevity.

In another implementation, the method 800 shown in fig. 8 may be used to determine the PUSCH transmit power for the terminal device 120. Illustratively, without being configured with the TPC accumulation parameter, the PUSCH power control adjustment value at the current time domain resource is determined based on the initial PUSCH power control adjustment value for the previous transmission opportunity of the current time domain resource and a PUSCH accumulation, where the accumulation is a PUSCH accumulation of power adjustment values indicated by power indication information in all DCI received between a first time associated with the previous transmission opportunity to a second time associated with the current time domain resource, at 820.

With regard to the first time and the second time, reference may be made to the description related to the first time and the second time in the above embodiments, and for the sake of brevity, this will not be repeated here.

The power adjustment value indicated by the TPC indication information may be determined from the first set of values. As one example, the TPC indication information may be a TPC command field parameter, and the power adjustment value indicated by the power indication information may be a TPC accumulated value of a PUSCH corresponding to the TPC command field parameter.

In some examples of this implementation, at least one of the elements in the first set of values is greater than 3, and/or at least one of the elements in the first set of values is less than-1.

In some examples of this implementation, the number of elements in the first set of values may be equal to4, or may be greater than 4. For example, the TPC indication information may be a TPC command field parameter, and the number of bits occupied by the TPC command field may be greater than 2, for example, 3, so that the TPC command field parameter may be a value from 0 to 7, and accordingly, the first value set may also include 8 elements, at least one of which is greater than 3 or at least one of which is smaller than-1.

In some examples, the first set of values is RRC configured or predefined.

In other examples, the first set of values is determined from at least two first sets. For example, the first set of values may be determined from the at least two first sets based on first set indication information in RRC signaling. As an example, the first set indication information may be an index. For example, the first set of values may be determined from the at least two first sets based on a predefined criterion. The predefined criteria may be a scenario for joint channel estimation, etc. As an example, the predefined criterion may be a gap length. The interval length is the length of the previous time domain resource or the length from the first transmission opportunity of the previous time domain resource to the first transmission opportunity of the current time domain resource.

Optionally, the at least two first sets may be predefined, e.g. preconfigured or pre-stored in various ways. In other examples, some or all of the at least two first sets may be configured through RRC signaling. In other examples, some or all of the at least two first sets may be indicated by DCI. In the embodiment of the present disclosure, the at least two first sets may also be configured in other manners, and the like, which are not listed here.

Optionally, part or all of the elements of the at least two first sets may be predefined or may be configured by RRC signaling.

Therefore, the embodiment of the disclosure expands the accumulated value of the TPC for the PUSCH, so that the range of the power control adjustment value is larger, the adjustment amount is finer, the power control adjustment range required by actual scenes such as joint channel estimation can be adapted, and the communication performance is ensured.

In another implementation, method 800 shown in fig. 8 can be used to determine PUCCH transmit power for terminal device 120. Illustratively, at 820, the PUCCH power control adjustment value for the current time domain resource is determined based on an initial power control adjustment value for a previous time domain resource of the current time domain resource and an accumulation, wherein the accumulation is an accumulation of power adjustment values indicated by power indication information in all DCI received between a first time associated with the previous time domain resource to a second time associated with the current time domain resource.

The power adjustment value indicated by the TPC indication information may be determined from a set of fetching values. As an example, the value set may be a TPC accumulated value, specifically, a TPC accumulated value of a PUCCH. For example, the TPC indication information may be a TPC command field parameter, and the power adjustment value indicated by the TPC indication information may be a TPC accumulated value of a PUCCH corresponding to the TPC command field parameter. For this embodiment, reference may be made to the above description in conjunction with table 4 and the like, and details are not repeated here for the sake of brevity.

In another implementation, method 800 shown in fig. 8 can be used to determine PUCCH transmit power for terminal device 120. Illustratively, at 820, a PUCCH power control adjustment value at the current time domain resource is determined based on an initial PUCCH power control adjustment value for a previous transmission opportunity of the current time domain resource and a PUCCH accumulation, wherein the accumulation is a PUCCH accumulation of power adjustment values indicated by power indication information in all DCI received between a first time associated with the previous transmission opportunity to a second time associated with the current time domain resource.

The power adjustment value indicated by the TPC indication information may be determined from the second set of values. As one example, the TPC indication information may be a TPC command field parameter, and the power adjustment value indicated by the power indication information may be a TPC accumulated value of a PUCCH corresponding to the TPC command field parameter.

In some examples of this implementation, at least one of the elements in the second set of values is greater than 3, and/or at least one of the elements in the second set of values is less than-1.

In some examples of this implementation, the number of elements in the second set of values may be equal to4, or may be greater than 4. For example, the TPC indication information may be a TPC command field parameter, and the number of bits occupied by the TPC command field may be greater than 2, for example, 3, so that the TPC command field parameter may be a value from 0 to 7, and accordingly, the second value set may also include 8 elements, where at least one is greater than 3 or at least one is smaller than-1.

In some examples, the second set of values is RRC configured or predefined.

In other examples, the second set of values is determined from at least two second sets. For example, the second set of values may be determined from the at least two second sets based on second set indication information in RRC signaling. As an example, the second set indication information may be an index. For example, the second set of values may be determined from the at least two second sets based on a predefined criterion. The predefined criteria may be a scenario for joint channel estimation, etc. As an example, the predefined criterion may be the interval length. The interval length is the length of the previous time domain resource or the length from the first transmission opportunity of the previous time domain resource to the first transmission opportunity of the current time domain resource.

Optionally, the at least two second sets may be predefined, e.g. preconfigured or pre-stored in various ways. In other examples, some or all of the at least two second sets may be configured through RRC signaling. In some other examples, some or all of the at least two second sets may be indicated by DCI. In the embodiment of the present disclosure, the at least two second sets may also be configured in other manners, and the like, which are not listed here.

Optionally, part or all of the elements of the at least two second sets may be predefined or may be configured by RRC signaling.

Therefore, the extension of the accumulated TPC value of the PUCCH is realized in the embodiment of the disclosure, so that the range of the power control adjustment value is larger, the adjustment amount is finer, the power control adjustment amplitude required by actual scenes such as joint channel estimation can be more adapted, and the communication performance is ensured.

It will be appreciated that in some embodiments, the current time domain resource comprises at least two transmission occasions, and the previous time domain resource may comprise one or more transmission occasions. Taking a time domain resource as a time domain window as an example, in one example, as shown in fig. 3, a current time domain resource (e.g., time domain window 320) includes 4 transmission opportunities, and a previous time domain resource (e.g., time domain window 310) includes 4 transmission opportunities. In another example, as shown in fig. 5, a current time domain resource (e.g., time domain window 513) includes 4 transmission opportunities and a previous time domain resource (e.g., time domain window 512) includes 1 transmission opportunity.

It is to be appreciated that in other embodiments, the current transmission resource comprises one transmission opportunity, e.g., the current transmission resource is a separate transmission opportunity for joint channel estimation, or the current transmission resource is not a separate transmission opportunity for joint channel estimation, and the previous time domain resource comprises at least two transmission opportunities. In one example, as shown in fig. 5, assume that the current time domain resource is a time domain window 512, which includes one transmission opportunity. The former time domain resource is a time domain window 511, which includes two transmission occasions.

In another implementation, the method 800 shown in fig. 8 may be used to determine the PUSCH transmit power for the terminal device 120. Illustratively, with the TPC accumulation parameter configured, at 820, a power control adjustment value at the current time domain resource is determined based on the scaling factor and the power adjustment value indicated by the TPC indication information.

In some examples, the scale factor may be pre-configured or pre-defined. That is to say, the scale factor is a predetermined value, so that the predefined scale factor can be directly obtained to determine the power control adjustment value, the efficiency is high, and the computational complexity of the terminal device is reduced.

In other examples, the scaling factor may be determined based on a third message, which may be carried in RRC signaling.

For example, the third message may include a scaling factor, so that the terminal device 120 may directly obtain the scaling factor from the third message, which is fast and efficient, and reduces the computational complexity of the terminal device.

In other examples, the scaling factor may be determined based on a third message and a fourth message, wherein the third message may be carried in RRC signaling and the third message includes a plurality of scaling factors, and wherein the fourth message may be DCI or a Medium Access Control-Control Element (MAC-CE). The fourth message is used to determine one of a plurality of scale factors.

In particular, terminal device 120 may receive a third message that includes a plurality of scale factors. Terminal device 120 may receive a fourth message that includes scale factor indication information. The terminal device 120 further acquires the scale factor indicated by the scale factor indication information from the plurality of scale factors. The scaling factor can be determined based on the third message and the fourth message, so that the configuration can be semi-statically performed by RRC and indicated by the DCI or the MAC-CE, the excessive signaling overhead of the DCI or the MAC-CE can be avoided, and the scaling factor can be updated more quickly and more flexibly.

In other examples, the scaling factor may be determined based on a predefined criterion. For example, the predefined criterion is a gap length, which is a length of a previous time domain resource or a length between a first transmission occasion of the previous time domain resource and a first transmission occasion of a current time domain resource.

In one example, the interval length may be used as a scaling factor, for example, a dimensionless value of the interval length after dimensioning is used as the scaling factor.

In another example, the scaling factor corresponding to the interval length can be obtained based on a corresponding relationship between the interval length and the scaling factor, wherein the corresponding relationship is configured or predefined by the RRC of the access network device.

In yet another example, the scaling factor may be determined based on the interval length and a predefined scaling factor. For example, the product of the interval length and the scaling factor is taken as the scaling factor.

It is understood that lengths in embodiments of the present disclosure may be at least one of: the number of slots, the number of symbols, the number of transmission opportunities, the number of repetitions, etc., wherein the number of repetitions may be a nominal number of repetitions or an actual number of repetitions, etc., and the disclosure is not limited thereto.

In other examples, the scaling factor may be determined based on the third message and a predefined criterion. The third message is carried in RRC signaling, and the predefined criterion is an interval length, where the interval length is a length of a previous time domain resource or a length from a first transmission opportunity of the previous time domain resource to a first transmission opportunity of a current time domain resource.

For example, if the third message includes a scaling factor, the product of the interval length and the scaling factor may be used as the scaling factor.

In other examples, the scaling factor may be determined based on the fourth message and a predefined criterion. The fourth message is DCI, and the predefined criterion is a gap length, where the gap length is a length of a previous time domain resource or a length from a first transmission opportunity of the previous time domain resource to a first transmission opportunity of a current time domain resource.

For example, if the fourth message includes a scaling factor, then the product of the interval length and the scaling factor may be used as the scaling factor.

In other examples, the scaling factor may be determined based on the third message, the fourth message, and a predefined criterion. The third message is carried in RRC signaling, the fourth message is DCI or AMC-CE, and the predefined criterion is the gap length.

For example, the third message includes a plurality of scaling factors, and the fourth message includes scaling factor indication information, then the scaling factor indicated by the scaling factor indication information may be obtained from the plurality of scaling factors, and then the product of the interval length and the scaling factor may be used as the scaling factor.

In some embodiments, the power adjustment value indicated by the TPC indication information may be determined from a set of values.

Optionally, the value set or elements in the value set may be predefined.

In one example, the TPC indication information may be a TPC command field parameter, and the power adjustment value indicated by the TPC indication information may be a TPC absolute value corresponding to the TPC command field parameter. As shown in table 2 above, the power adjustment value indicated by the TPC indication information may be determined from a set of values { -4, -1, 4 }.

In another example, in the value set in which the power adjustment value indicated by the TPC indication information is located, the value of at least one element is greater than 4. For example, the set of values can be { -6, -1, 6} or { -8, -2, 8} or the like.

In another example, in the value set in which the power adjustment value indicated by the TPC indication information is located, the number of included elements is greater than 4. For example, the TPC indication information may be a TPC command field parameter, and the number of bits occupied by the TPC command field may be greater than 2, for example, 3, so that the TPC command field parameter may be a value from 0 to 7, and accordingly, the value set may also include 8 elements, where at least one is greater than 4. For example, the set of values can be { -6, -4, -2, -1, 2,4,6} or the like.

In some embodiments, the value set or elements in the value set are configured by the RRC, so that the terminal device 120 can determine the indicated power adjustment value from the value set based on the TPC indication information.

In some embodiments, the set of values may be determined from at least two sets of values (hereinafter referred to as at least two sets).

In one example, a set of values can be determined from at least two sets based on set indication information in RRC signaling.

For example, the set indication information may be an index. At least two sets may have corresponding indices, with different sets having different indices. Then the corresponding set of values may be determined based on an index in the RRC signaling. Taking Table 5 as an example, there are two sets of absolute TPC values for JCE, namely { -6, -1, 6} and { -8, -2, 8}, respectively. Suppose the index of the set { -6, -1, 6} is A1 and the index of the set { -8, -2, 8} is A2. Then, if the index in the RRC signaling is A1, the set of values can be determined to be { -6, -1, 6}. If the index in the RRC signaling is A2, the set of values can be determined to be { -8, -2, 8}. It is understood that the set indication information may be in other forms, and is not listed here.

TABLE 5

In another example, a set of values may be determined from the at least two sets based on a predefined criterion. The predefined criteria may be a scenario for joint channel estimation, etc.

Taking table 5 as an example, there are two sets corresponding to the TPC command field, which are: TPC absolute value and TPC absolute value for JCE. Then in determining the transmit power of the current time domain resource for joint channel estimation, the column in which the TPC absolute value for JCE is located can be determined as the set of values, i.e., { -6, -1, 6}.

In yet another example, a set of values may be determined from the at least two sets based on a predetermined criterion. The predefined criterion may be the interval length. The interval length is the length of the previous time domain resource or the length from the first transmission opportunity of the previous time domain resource to the first transmission opportunity of the current time domain resource.

Taking table 6 as an example, there are two sets corresponding to the TPC command field, which are: interval length =3 TPC absolute value for JCE and interval length =2 TPC absolute value for JCE. Then, the terminal device 120 may first determine the interval length, and may further determine a value set based on the interval length.

TABLE 6

Therefore, by expanding the TPC command field in the row and/or column direction, the method can adapt to the actually required power adjustment range, and ensures the communication performance. Specifically, the TPC absolute value is expanded, and the expansion is not only related to a TPC command field, but also related to the interval length, so that the range of a power control adjustment value is larger, the adjustment amount is finer, the power control adjustment range required by an actual scene can be adapted, and the communication performance is ensured.

It should be noted that table 6 is merely illustrative, and that a certain column of absolute values of TPC for a JCE may correspond to one or more interval lengths, e.g., interval lengths of 3 or 4 all correspond to column 2 of table 6, and interval lengths of 1 or 2 all correspond to column 3 of table 6; alternatively, a certain column of TPC absolute values for a JCE may correspond to an interval of interval length, e.g., interval length in interval (2, 4] for column 2 of Table 6 and interval length in interval (0, 2] for column 3 of Table 6. Alternatively, TPC absolute values for a JCE may include more or fewer columns.

In addition, it is understood that the value sets may be determined from the at least two sets in other manners, which are not listed one by one.

In some examples, the at least two sets may be predefined, for example preconfigured or pre-stored in various ways. In other examples, some or all of the at least two sets may be configured through RRC signaling. In other examples, some or all of the at least two sets may be indicated by DCI. In the embodiment of the present disclosure, at least two sets may also be configured in other manners, and the like, which are not listed here.

In some embodiments, determining 820 a power control adjustment value at the current time domain resource may include: a power control adjustment value for each transmission opportunity of the current time domain resource is determined.

In some embodiments, determining 820 a power control adjustment value at the current time domain resource may include: a power control adjustment value for a first transmission opportunity of a current time domain resource is determined. Optionally, other transmission occasions (i.e. not the first transmission occasion) for the current transmission resource may be determined by other rules, for example, the other rules are: the transmit power of the other transmission occasions is equal to the transmit power of the first transmission occasion.

And, the power adjustment value (e.g., the TPC absolute value for JCE) corresponding to the TPC command indication information may have a larger value or a larger range, so that the actually required power adjustment amplitude can be adapted, and the communication performance is ensured.
