technical field

The present application belongs to the technical field of mobile communication, and in particular relates to a beam indicating method, device and terminal.

Background technique

After beam measurement and beam reporting, the network side can make beam indications for downlink and uplink channels or reference signals, which are used to establish beam links between the network and UE to realize the transmission of channels or reference signals. There are two ways of R17 beam indication: one is to follow the R15/16 beam indication legacy TCI, including transmission configuration indication (Transmission Configuration Indication, TCI) state (state)/spatial relation (spatial relation); the other is unified Transport configuration indication (unified TCI). For intra-cell (intra-cell) scenarios, a terminal, also called user equipment (User Equipment, UE), can receive/send all channels or reference signals according to the unified TCI activated/indicated by the network; for inter-cell (Inter-cell) cell) scenario, the beam indication is divided into two parts, in which UE can be used to receive/send non-UE-dedicated (non-UE-dedicated) channels/reference signals according to the R15 TCI state activated/indicated by the network, and according to the network activated/indicated The R17 unified TCI associated with the target cell corresponding to the PCI different from the PCI of the current cell is used to receive/send the terminal-dedicated (UE-dedicated) channel or reference signal.

In this case, there is the following problem: In the case where the above two beam indication methods are both working, due to the existence of cross-point non-UE-dedicated channel/reference signal, the UE cannot clearly determine the non-UE-dedicated channel/reference signal The beam of the reference signal, resulting in poor quality of the received signal; in the case where the above two beam indication mechanisms are working, that is, both inter-cell beam indication and intra-cell beam indication are working, different beam indication mechanisms can use different signal Therefore, there are no clear rules on how to determine or update the beam information of different channels and/or reference signals under various signalings carrying beam indication information; both of the above two beam indication signaling mechanisms work In the case of , since there are two types of transmission channels or reference signals, non-UE-dedicated channel or reference signal and UE-dedicated channel or reference signal, the default beam of the Physical downlink shared channel (PDSCH) defined in R15 cannot be distinguished, so it is not suitable for R17 scenarios.

It can be seen that, in the above situation, the terminal cannot determine or update the channel and/or reference signal beam information, so that the transmission of the channel or reference signal fails, affecting the reliability of data transmission.

The joint TCI, DL TCI and UL TCI all belong to the unified TCI architecture. The unified TCI can adopt two schemes, one is joint TCI, that is, the uplink and downlink use one beam uniformly; the other is separate transmission configuration indication (separate TCI), indicating information by a pair of beams, one for the DL TCI applied to the downlink and one for the UL TCI applied to the uplink.

It should be understood that the target cell is a cell corresponding to a PCI different from the physical cell identifier (Physical Cell Identifier, PCI) of the current cell, and the current cell is the current serving cell.

It can be seen from the above technical solutions provided by the embodiments of the present invention that in the embodiments of the present application, the terminal receives the signaling containing the beam indication information; the terminal determines or updates the first channel and/or the reference signal according to the preset rules according to the signaling. The beam information is used for receiving and/or sending, so that the terminal can accurately determine or update the channel and/or reference signal beam information to realize accurate transmission of the channel and/or reference signal, and improve the reliability of data transmission.

Based on the above embodiment, further, as shown in FIG. 3, the steps S210-S220 may include:

Step S310, the terminal receives first signaling carrying beam indication information.

It should be understood that the first signaling refers to MAC CE signaling received when the first beam indication signaling mechanism is adopted. The first beam indication signaling mechanism may also be expressed as an only MAC CE beam indication signaling mechanism, which means that both legacy TCI and unified TCI indicate beam information only through MAC CE signaling.

Further, before the step S310, the method may also include:

The terminal determines or switches the beam indication signaling mechanism according to the signaling including the beam indication information, and performs the following steps when it is determined to adopt the first beam indication signaling mechanism.

Step S320, the terminal determines or updates the first beam information of the first channel and/or reference signal according to the first preset rule according to the first signaling.

In one embodiment, the first preset rule includes at least one of the following:

In the case where the first channel and/or reference signal is the UE-dedicated channel and/or reference signal, the first beam information according to before the UE-dedicated channel and/or reference signal starts to transmit, determine the joint TCI in the first signaling carrying the joint TCI that is closest to the first symbol of the UE-dedicated channel and/or the reference signal and is effective;

In the case where the first channel and/or reference signal is the DL UE-dedicated channel and/or reference signal, the first beam information starts transmission according to the DL UE-dedicated channel and/or reference signal Previously, the DL TCI in the first signaling carrying the DL TCI that is nearest to the first symbol of the DL UE-dedicated channel and/or the reference signal and is in effect is determined;

In the case where the first channel and/or reference signal is the UL UE-dedicated and/or reference signal, the first beam information is based on the UL UE-dedicated channel and/or reference signal before transmission starts , determining the UL TCI in the first signaling carrying the UL TCI that is nearest to the first symbol of the UL UE-dedicated channel and/or reference signal and is effective;

In the case where the first channel and/or reference signal is a DL Non-UE-dedicated channel and/or reference signal, the first beam information or part of the first beam information is based on the DL Non-UE-dedicated Before the transmission of the channel and/or reference signal starts, the beam indication information in the second signaling that is closest to the first symbol of all or part of the DL Non-UE-dedicated channel and/or reference signal and takes effect is determined;

Wherein, the beam indication information in the second signaling includes at least one of the following:

joint TCI not associated with the target cell;

DL TCI not associated with the target cell;

TCI state, the TCI state here is the legacy TCI state of R15/16.

Wherein, the entry into force refers to one of the following situations:

The beam information carried in the signaling can only work after a preset time, such as Y symbols or X ms, after the Hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback of the channel carrying the signaling ;

The beam information carried in the signaling can work only after a preset time, for example, Y symbols, after the last symbol of the channel carrying the signaling.

Wherein, the preset time, such as Y symbols or X ms, may be determined by the network side according to the capability of the terminal.

An example for determining the first beam information under the first beam indication signaling mechanism is given below.

The form of the first signaling under the first beam indication signaling mechanism may include five MAC CE signaling formats as shown in FIG. 4 .

Among them, MAC CE#1 is the MAC CE signaling format of legacy TCI state carrying TCI state#1, and MAC CE#2~5 are MAC CE formats of unified TCI. The joint TCI carried in MAC CE#2 is not associated with the current serving cell or service transmission and reception point (Transmission and Reception Point, TRP); the UL TCI and DL TCI carried in MAC CE#3 are both associated with the current serving cell or service TRP; MAC CE#4 carries DL TCI associated with the target cell or target TRP, and MAC CE#5 carries UL TCI and DL TCI associated with the target cell or target TRP. The PCI#1 is the PCI of the target cell. In order to visually reflect whether the corresponding TCI is associated with the target cell by marking the PCI, the actual MAC CE signaling may not carry PCI, and the PCI#1 in the brackets of MAC CE#2 indicates that the joint TCI can Associate the target cell.

As shown in Figure 5, the arrival time of the MAC CE carrying different beam indications for the above five types, the time for replying to the corresponding HARQ-ACK feedback, and the valid time of each MAC CE are shown in Figure 5. The above five types Under the MAC CE carrying different beam indication information, the channel and/or beam information changes of the reference signal at different times are shown in Table 1 below.

Table 1

Among them, A is a certain moment after t14.

As shown in Table 1:

[t0, t10]: Since before t10, all the beam information determined by the MAC CE has not yet taken effect, at this time, the beam information of all channels and/or reference signals can be determined according to the default beam mechanism and the initial access of the terminal SSB correlation of the current serving cell;

[t10-t11]: The beam information TCI state#1 carried in MAC CE#1 takes effect at t10, but since TCI state#1 is only applicable to non-UE-dedicated channels and/or reference signals, UE-dedicated channels and /or the beam information of the reference signal remains unchanged for a period of time, and is related to the SSB of the terminal's initial access to the current serving cell;

[t11-t12]: The beam information TCI state-r17#2 carried in MAC CE#2 takes effect at t11. Since TCI state-r17#2 is a joint TCI and is not associated with the target cell, it is applicable to all channels and/or Reference signal, the beam information of all channels and/or reference signals are updated to TCI state-r17#2;

[t12-t13]: The beam information carried in MAC CE#3 UL TCI—TCI state-r17#3 and DL TCI—TCI state-r17#4 take effect at t12, TCI state-r17#3 and TCI state-r17# 4 are not associated with the target cell, and apply to all UL channels and/or reference signals and DL channels and/or reference signals respectively, so the beam information of all UL channels and/or reference signals are updated to TCI state-r17#3, Beam information of all DL channels and/or reference signals are updated to TCI state-r17#4;

[t13-t14]: The beam information UL TCI—TCI state-r17#5 and DL TCI—TCI state-r17#6 carried in MAC CE#4 take effect at t13. Since TCI state-r17#5 is associated with the target cell, So TCI state-r17#5 applies only to UL UE-dedicated channels and/or reference signals, while TCI state-r17#6 applies to all DL channels and/or reference signals, so UL UE-dedicated channels and/or reference signals The beam information of all DL channels and/or reference signals is updated to TCI state-r17#5, the beam information of UL non-UE-dedicated channels and/or reference signals remains unchanged, and the beam information of all DL channels and/or reference signals is updated to TCI state-r17 #4;

[t14-A]: The beam information UL TCI—TCI state-r17#7 and DL TCI—TCI state-r17#8 carried in MAC CE#5 take effect at t14, because TCI state-r17#7 and TCI state-r17 #8 is associated with the cell corresponding to the PCI different from the PCI of this cell, so TCI state-r17#7 and TCI state-r17#8 are only applicable to UL UE-dedicated channels and/or reference signals and DL UE dedicated channels and /or reference signal. Therefore, the beam information of UL UE-dedicated channel and/or reference signal is updated to TCI state-r17#7, the beam information of DL UE-dedicated channel and/or reference signal is updated to TCI state-r17#8, all non-UE - The beam information of the dedicated channel and/or reference signal remains unchanged;

Assuming that MAC CE#5 carries a joint TCI associated with the target cell—TCI state-r17#9, after t14 takes effect, the beam information of all UE-dedicated channels and/or reference signals will be updated to TCI state-r17#9 , while the beam information of non-UE-dedicated channels and/or reference signals remains unchanged.

It can be seen from the technical solutions provided by the above embodiments of the present invention that in the embodiments of the present application, under the only MAC CE beam indication signaling mechanism, according to receiving the first signaling carrying beam indication information; the terminal according to the first signaling , determine or update the first beam information of the first channel and/or reference signal according to the first preset rule, so that the terminal can accurately determine or update the channel and/or reference signal beam under the only MAC CE beam indication signaling mechanism information to achieve accurate transmission of channel and/or reference signals and improve the reliability of data transmission.

Based on the above embodiment, further, as shown in FIG. 6, the steps S210-S220 further include:

Step S610, the terminal receives fourth signaling and fifth signaling carrying beam indication information.

It should be understood that the fourth signaling and the fifth signaling are MAC CE signaling as the fourth signaling and DCI signaling as the fifth signaling received under the second beam indication signaling mechanism. The second beam indication signaling mechanism can also be expressed as only MAC CE+DCI beam indication signaling mechanism, which refers to indicating beam information through MAC CE+DCI, specifically, multiple beam indication information can be activated by MAC CE signaling. A beam information set is obtained from TCI codepoints, and then the beam indication information contained in the DCI is used to determine one of the TCI codepoints from the beam information set to determine the beam information.

Further, before the step S610, the method also includes:

The terminal determines or switches the beam indication signaling mechanism according to the signaling including the beam indication information, and performs the following steps when it is determined to adopt the second beam indication signaling mechanism.

Step S620, the terminal determines or updates the second beam information of the first channel and/or the reference signal according to the second preset rule according to the fourth signaling and the fifth signaling.

In one embodiment, the second preset rule includes:

Wherein, the second channel and/or reference signal is one of the following:

said first channel and/or reference signal;

Carrying the fifth signaling channel or reference signal that carries beam indication information and takes effect and is nearest to the first symbol of the first channel and/or reference signal before the transmission of the first channel and/or reference signal starts .

In an implementation manner, the determining the beam information set of the first channel and/or reference signal according to the beam indication information in the effective fourth signaling includes:

According to the beam indication information in the fourth signaling that carries the first beam indication information and is effective before the transmission of the second channel and/or reference signal is closest to the first symbol of the second channel and/or reference signal Determine the first beam information set of the UE-dedicated channel and/or reference signal; wherein the first beam indication information includes at least one of the following: joint TCI, DL TCI and UL TCI;

In an embodiment, according to the beam indication information in the effective fifth signaling, the first channel and/or reference signal of the first channel and/or reference signal is determined in the beam information set of the first channel and/or reference signal Two-beam information, including at least one of the following:

It is assumed that the effective time of the corresponding relationship between TCI codepoints and TCI states activated by the MAC CE is the Xms time after the time slot occupied by the HARQ-ACK corresponding to the PDSCH carrying the MAC CE, for example, the first time slot after 3 ms; In consideration of the time for PDCCH decoding and beam switching by hardware devices, the beam information determined by the DCI can only take effect after Y symbols after the last symbol of the PDCCH. Table 2, Table 3, and Table 4 below show the formats of three fourth signalings, which are MAC CE#1 signaling, MAC CE#2 signaling, and MAC CE#3 signaling.

It can be seen from the technical solutions provided by the above embodiments of the present invention that in the embodiments of the present application, under the only MAC CE+DCI beam indication signaling mechanism, according to receiving the fourth signaling and the fifth signaling carrying beam indication information; the terminal According to the fourth signaling and the fifth signaling, determine or update the second beam information of the first channel and/or reference signal according to the second preset rule, so that the terminal can indicate signaling in only MAC CE+DCI beam Under the mechanism, accurately determine or update channel and/or reference signal beam information to realize accurate transmission of channel and/or reference signal and improve the reliability of data transmission.

Based on the above embodiment, further, as shown in FIG. 8, the steps S210-S220 further include:

Step S810, the terminal receives the first signaling, the fourth signaling and the fifth signaling carrying beam indication information.

It should be understood that the first signaling is MAC CE signaling received when the first beam indication signaling mechanism is adopted, and the first beam indication signaling mechanism is an only MAC CE mechanism. The fourth signaling and the fifth signaling are the received MAC CE signaling as the fourth signaling and the DCI signaling as the fifth signaling when the second beam indication signaling mechanism is adopted, so The second beam indication signaling mechanism is the MAC CE+DCI beam indication signaling mechanism.

Further, before the step S810, the method may also include:

The terminal determines or switches the beam indication signaling mechanism according to the signaling containing the beam indication information, and when it is determined to use the first beam indication signaling mechanism and the second beam indication signaling mechanism at the same time, that is, for different beams The indication mode adopts different beam indication signaling mechanisms, for example, the first beam indication signaling mechanism is adopted for legacy TCI state, and the second beam indication signaling mechanism is adopted for unified TCI, and the following steps are performed.

Step S820, the terminal determines or updates third beam information of the first channel and/or reference signal according to a third preset rule according to the first signaling, the fourth signaling and the fifth signaling.

In one embodiment, the third preset rule includes at least one of the following:

The third beam information is determined by determining or updating the first beam information of the first channel and/or reference signal according to the first preset rule according to the first signaling;

The third beam information is determined by determining or updating the second beam information of the first channel and/or reference signal according to the second preset rule according to the fourth signaling and the fifth signaling;

The third beam information is determined for the beam information whose effective time is closest to the target symbol of the first channel and/or reference signal among the first beam information and the second beam information.

An example of determining the third beam information under the simultaneous adoption of the first beam indication signaling mechanism and the second beam indication signaling mechanism is given below.

Take legacy TCI state adopts only MAC CE beam indication signaling mechanism, and unified TCI adopts MAC CE+DCI beam indication signaling mechanism as an example. As shown in FIG. 9 , the arrival time and effective time of each of the first signaling, the fourth signaling and the fifth signaling are given. Among them, it is assumed that MAC CE#1 is a TCI carrying legacy TCI state indication information, as shown in MAC CE#1 in Figure 4, and MAC CE#2 is TCI codepoints carrying multiple unified TCI indication information, as shown in Table 3 above Indicates that DCI#0 determines a TCI codepoint from multiple TCI codepoints indicated by MAC CE#2. According to the third preset rule, beam information of different channels and/or reference signals at different times may be determined as follows. Take [t4, t7] and [t7, A] as an example.

[t4, t7]: According to the first preset rule, according to the only MAC CE beam indication signaling mechanism, it can be determined that the effective beam information in the current time period is TCI state#1, and according to the MAC CE+DCI beam indication signaling mechanism Although the multiple TCI codepoint information carried by the MAC CE takes effect at t5, the DCI signaling has not been detected or taken effect, so no unified TCI takes effect. The combination of the two mechanisms judges that the effective beam information in the current time period is TCI state#1. Therefore, the beam information of DL non-UE-dedicated PDCCH in the current period will be determined according to TCI state#1, while the beam information of other channels and/or reference signals is determined according to the default beam mechanism.

[t7, A]: According to the first preset rule, according to the only MAC CE beam indication signaling mechanism, it can be determined that the first beam information effective in the current time period is TCI state#1; due to the MAC CE+DC beam indication signaling mechanism The multiple TCI codepoint information carried by the MAC CE in DCI has taken effect at t5, and the beam information indicated by the DCI signaling also takes effect at t7. Therefore, according to the second preset rule, if the value of the TCI field in DCI#0 is 0 , the second beam information effective in the current time period is joint TCI—TCI state-r17#1. The two mechanisms are combined to judge. Since TCI state-r17#1 is closest to the first symbol of all channels or signals in the current period and is not associated with the joint TCI of the target cell to indicate the beam information of all channels, the beam information of all channels will be Determined according to TCI state-r17#1; if the value of the TCI field in DCI#0 is 3, the second beam information effective in the current time period is separate TCI—(UL TCI:TCI state-r17#6, associated PCI DL for #1:TCI state-r17#7). For the UL channel and/or reference signal, since the available beam information is not indicated in MAC CE#1, the current time period, the UL channel and/or reference signal is determined according to TCI state-r17#6; for the DL channel and/or Reference signal, although TCI state-r17#7 is the latest effective beam information, but because it is associated with the target cell, it can only determine the beam information of DL UE-dedicated channel and/or reference signal in the current time period. The beam information of DL non-UE-dedicated channel and/or reference signal can continue to be determined according to TCI state#1, or determined according to the default beam mechanism.

It can be seen from the above technical solutions provided by the embodiments of the present invention that in the embodiments of the present application, by using the first beam indication signaling mechanism and the second beam indication signaling mechanism at the same time, according to receiving the first signaling carrying beam indication information , the fourth signaling and the fifth signaling; the terminal determines or updates the first channel and/or the reference signal according to the third preset rule according to the first signaling, the fourth signaling and the fifth signaling The third beam information, so that the terminal can accurately determine or update the channel and/or reference signal beam information to realize the channel and/or reference signal while using the first beam indication signaling mechanism and the second beam indication signaling mechanism.
