Description

Technical Field

[0001] This application belongs to the field of mobile communication technology, and specifically relates to a beam pointing method, device and terminal. Background Technology

[0002] After beam measurement and beam reporting, the network side can perform beam indication on the downlink and uplink channels or reference signals to establish beam links between the network and the UE, enabling the transmission of channels or reference signals. R17 beam indication methods are divided into two types: one is the legacy TCI beam indication from R15 / 16, including Transmission Configuration Indication (TCI) state / spatial relation; the other is a unified TCI. In intra-cell scenarios, the terminal, also known as User Equipment (UE), can receive / transmit all channels or reference signals according to the unified TCI activated / indicated by the network. In inter-cell scenarios, beam indication is divided into two parts. The UE can receive / transmit non-UE-dedicated channels / reference signals according to the R15 TCI state activated / indicated by the network, and receive / transmit UE-dedicated channels or reference signals according to the R17 unified TCI associated with the target cell corresponding to a PCI different from the local cell's PCI activated / indicated by the network.

[0003] In this scenario, the following problems arise: When both beam indication methods are operational, the UE cannot clearly determine the beam of the non-UE-dedicated channel / reference signal due to the presence of an intersection point, resulting in poor received signal quality. When both beam indication mechanisms are operational (i.e., both inter-cell beam indication and intra-cell beam indication are working), different signaling methods can be activated and / or indicated using different signaling. Therefore, there are no clear rules for determining or updating the beam information of different channels and / or reference signals under various signaling methods carrying beam indication information. Furthermore, when both beam indication signaling mechanisms are operational, the existence of two types of transmission channels or reference signals—non-UE-dedicated channels or reference signals and UE-dedicated channels or reference signals—makes it unsuitable for the R17 scenario, as the default beam of the Physical Downlink Shared Channel (PDSCH) defined in R15 cannot be distinguished.

[0004] As can be seen, under the above circumstances, the terminal is unable to determine or update the channel and / or reference signal beam information, thereby causing the transmission of the channel or reference signal to fail and affecting the reliability of data transmission. Summary of the Invention

[0005] This application provides a beam indication method, apparatus, and terminal that can solve the problem that the terminal cannot determine or update the channel and / or reference signal beam information, thereby causing the transmission of the channel or reference signal to fail and affecting the reliability of data transmission.

[0033] The beam indication method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0034] like Figure 2 As shown in the figure, this application provides a beam indication method. The beam indication method can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. The method includes the following steps.

[0035] Step S210: The terminal receives signaling containing beam indication information;

[0036] Step S220: The terminal determines or updates the beam information of the first channel and / or reference signal according to the signaling and a preset rule, for receiving and / or transmitting.

[0037] When the terminal receives signaling containing beam indication information under different beam indication signaling mechanisms, it will determine or update the beam information of the first channel and / or reference signal according to the signaling containing beam indication information and using preset rules. Then, it will establish a beam link with the network side according to the determined or updated beam information to realize the transmission of the first channel and / or reference signal.

[0038] The preset rules can be varied according to actual needs. They can be used to determine which beam indication mechanism or beam indication signaling mechanism to use, or to determine which beam indication mechanism or beam indication signaling mechanism to use for different first channels and / or reference signals, or to determine or update which signaling containing beam indication information to adopt for different first channels and / or reference signals, or to determine or update which signaling containing beam indication information to prioritize among multiple received signaling signals containing beam indication information.

[0039] In one implementation, the signaling containing beam indication information takes one of the following forms:

[0040] Radio Resource Control (RRC) signaling;

[0041] Medium Access Control Element (MAC CE) signaling;

[0042] Downlink Control Information (DCI).

[0043] In one implementation, the first channel and / or reference signal includes at least one of the following:

[0044] UE-dedicated channels and / or reference signals;

[0045] Non-UE-dedicated channels and / or reference signals;

[0046] UE-dedicated uplink channel and / or reference signal;

[0047] UE-dedicated downlink (DL) channel and / or reference signal;

[0048] Non-UE-dedicated downlink (DL) channels and / or reference signals;

[0049] All channels and / or reference signals.

[0050] In one implementation, the Non-UE-dedicated channel and / or reference signal includes at least one of the following:

[0051] Channels and / or reference signals on the non-UE-dedicated control resource set (CORESET);

[0052] The associated channels and / or reference signals scheduled by the Physical downlink control channel (PDCCH) on the Non-UE-dedicated CORESET.

[0053] In one implementation, the PDCCH scheduling-related channels include at least one of the following:

[0054] PDSCH scheduled by the PDCCH;

[0055] The Physical Uplink Shared Channel (PUSCH) scheduled by the PDCCH;

[0056] The PUCCH containing the feedback information of the PDSCH scheduled by the PDCCH;

[0057] The PUCCH containing the feedback information corresponding to the PUSCH scheduled by the PDCCH.

[0058] In one implementation, the Non-UE-dedicated CORESET is at least one of the following:

[0059] The associated search space set (SS set) is a control resource set of the common search space set (CSS set);

[0060] The associated SS set contains at least one CORESET of the Common Search Space set;

[0061] Control resource set 0 (CORESET#0).

[0062] In one implementation, the beam indication information includes at least one of the following:

[0063] Beam indication information directly associated with the target cell;

[0064] Beam indication information indirectly associated with the target cell;

[0065] Beam indication information not associated with the target cell;

[0066] Among them, the various beam indication information includes at least one of the following beam information:

[0067] Transmission Configuration Indicator state (TCIstate), where TCI refers to the legacy TCI state defined in R15 / 16;

[0068] Joint Transport Configuration Indicator (joint TCI);

[0069] Downlink Transmission Configuration Indicator (DL TCI);

[0070] Uplink Transmission Configuration Indicator (UL TCI).

[0071] 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, which uses a single beam for both uplink and downlink; the other is separate transmission configuration indication (separate TCI), which consists of a pair of beam indication information, one for the downlink DL TCI and one for the uplink UL TCI.

[0072] It should be understood that the target cell is a cell with a different PCI than the physical cell identifier (PCI) of this cell, and this cell is the current serving cell.

[0073] It should be understood that the beam indication information directly associated with the target cell includes at least one of the joint TCI, DL TCI, or UL TCI directly associated with the cell corresponding to a PCI different from the PCI of this cell. Specifically, it can refer to the quasi-co-location (QCL) resource reference signal (RS) in the TCI state of the beam indication information being associated with the cell corresponding to a PCI different from the PCI of this cell.

[0074] It should be understood that the beam indication information indirectly associated with the target cell includes at least one of joint TCI, DL TCI or UL TCI indirectly associated with a cell corresponding to a PCI different from the PCI of this cell. Specifically, it can refer to the QCL resource RS of the TCI state in the beam indication information being associated with a cell corresponding to a PCI different from the PCI of this cell.

[0075] There are various ways to directly or indirectly associate with the target cell. In one implementation, the beam indication information associated with the target cell satisfies at least one of the following:

[0076] PCI that includes or is associated with the target cell;

[0077] Indications that include or are associated with information related to the target cell, such as determining the cell information of the target cell associated with the TCI indicated by the network through bit mapping.

[0078] It should be understood that the beam indication information not associated with the target cell may include at least one of the joint TCI, DL TCI or UL TCI of a cell with a PCI different from the PCI of this cell, and may also include the TCI state of a cell with a PCI different from the PCI of this cell, where the TCI state is the legacy TCI state defined in R15 / 16.

[0079] The phrase "not associated with the target cell" can specifically include the following two situations:

[0080] The default association can be to not associate with the TCI of a cell corresponding to a PCI that is different from the PCI of this cell;

[0081] Associated with this community.

[0082] As can be seen from the technical solutions provided by the above embodiments of the present invention, the embodiments of this application receive signaling containing beam indication information through a terminal; the terminal determines or updates the beam information of the first channel and / or reference signal according to the signaling and a preset rule, for receiving and / or transmitting, thereby enabling the terminal to accurately determine or update the beam information of the channel and / or reference signal to achieve accurate transmission of the channel and / or reference signal and improve the reliability of data transmission.

[0083] Based on the above embodiments, further, as Figure 3 As shown, steps S210-S220 may include:

[0084] Step S310: The terminal receives a first signaling message carrying beam indication information.

[0085] It should be understood that the first signaling refers to the MAC CE signaling received under the first beam indication signaling mechanism. The first beam indication signaling mechanism can also be expressed as the only MAC CE beam indication signaling mechanism, which means that both legacy TCI and unified TCI indicate beam information only through MAC CE signaling.

[0086] Furthermore, prior to step S310, the method may further include:

[0087] The terminal determines or switches the beam indication signaling mechanism based on the signaling containing beam indication information, and performs the following steps if it determines that the first beam indication signaling mechanism is adopted.

[0088] 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 based on the first signaling.

[0089] In one implementation, the first preset rule includes at least one of the following:

[0090] In the case that the first channel and / or reference signal is the UE-dedicated channel and / or reference signal, the first beam information is determined based on the joint TCI in the first signaling carrying the joint TCI that is closest to and active to the first symbol of the UE-dedicated channel and / or reference signal before the transmission of the UE-dedicated channel and / or reference signal begins;

[0091] When the first channel and / or reference signal is the DL UE-dedicated channel and / or reference signal, the first beam information is determined based on the DL TCI in the first signaling carrying the DL TCI that is closest to and active to the first symbol of the DL UE-dedicated channel and / or reference signal before the DL UE-dedicated channel and / or reference signal begins transmission;

[0092] In the case that the first channel and / or reference signal is the UL UE-dedicated and / or reference signal, the first beam information is determined based on the UL TCI in the first signaling carrying the UL TCI that is closest to and active to the first symbol of the UL UE-dedicated channel and / or reference signal before the UL UE-dedicated channel and / or reference signal begins transmission;

[0093] In the case that 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 determined based on the beam indication information in the second signaling that is closest to and active to the first symbol of all or part of the DL Non-UE-dedicated channel and / or reference signal before the transmission of the DL Non-UE-dedicated channel and / or reference signal begins;

[0094] The beam indication information in the second signaling includes at least one of the following:

[0095] Joint TCIs not associated with the target cell;

[0096] DL TCI not associated with the target cell;

[0097] TCI state, here the TCI state is the R15 / 16 legacy TCI state.

[0098] The term "effective" refers to one of the following situations:

[0099] The beam information carried in the signaling can only be used after a preset time, such as Y symbols or X ms, following the feedback of the Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) of the channel carrying the signaling;

[0100] The beam information carried in the signaling can only be used after a preset time, for example, Y symbols, following the last symbol of the channel carrying the signaling.

[0101] The preset time, such as Y symbols or X ms, can be determined by the network side based on the terminal's capabilities.

[0102] The following is an example of determining the first beam information under the first beam indication signaling mechanism.

[0103] The form of the first signaling under the first beam indication signaling mechanism may include, for example: Figure 4 The five MACCE signaling formats shown are as follows.

[0104] In this configuration, MAC CE#1 is the MAC CE signaling format for the legacy TCI state, carrying TCI state#1. MAC CE#2 to 5 are the MAC CE formats for the unified TCI. The joint TCI carried in MAC CE#2 is not associated with the current serving cell or serving 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 serving TRP. MAC CE#4 carries a DL TCI associated with the target cell or target TRP. MAC CE#5 carries both UL TCI and DL TCI associated with the target cell or target TRP. PCI#1 is the PCI of the target cell. The PCI is labeled to visually indicate whether the corresponding TCI is associated with the target cell; however, the PCI may not be carried in the actual MAC CE signaling. The PCI#1 in parentheses in MAC CE#2 indicates that the joint TCI can be associated with the target cell.

[0105] like Figure 5 As shown, the arrival times of the five MAC CEs carrying different beam indicators, the corresponding HARQ-ACK feedback times, and the valid times of each MAC CE are given. Figure 5 As shown in Table 1, the beam information changes of the channel and / or reference signal at different times under the above five types of MAC CEs carrying different beam indication information are as follows.

t14-A

[0116] Assuming 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 will remain unchanged.

[0117] As can be seen from the technical solutions provided by the above embodiments of the present invention, the embodiments of this application, under the only MAC CE beam indication signaling mechanism, receive a first signaling carrying beam indication information; the terminal determines or updates the first beam information of the first channel and / or reference signal according to the first signaling and a first preset rule, thereby enabling the terminal to accurately determine or update the beam information of the channel and / or reference signal under the only MAC CE beam indication signaling mechanism to achieve accurate transmission of the channel and / or reference signal and improve the reliability of data transmission.

[0118] Based on the above embodiments, further, as Figure 6 As shown, steps S210-S220 further include:

[0119] Step S610: The terminal receives the fourth and fifth signaling messages carrying beam indication information.

[0120] It should be understood that the fourth and fifth signaling are the MAC CE signaling received as the fourth signaling and the DCI signaling received as the fifth signaling under the second beam indication signaling mechanism. The second beam indication signaling mechanism can also be expressed as a MAC CE+DCI beam indication signaling mechanism, which means that beam information is indicated by MAC CE+DCI. Specifically, the beam indication information contained in the MAC CE signaling can activate multiple Transmission Configuration Indicator Codepoints (TCI codepoints) to obtain a beam information set, and then the beam indication information contained in the DCI can determine one of the TCI codepoints from the beam information set to determine the beam information.

[0121] Furthermore, prior to step S610, the method further includes:

[0122] The terminal determines or switches the beam indication signaling mechanism based on the signaling containing beam indication information, and performs the following steps if it determines that the second beam indication signaling mechanism is adopted.

[0123] Step S620: The terminal determines or updates the second beam information of the first channel and / or reference signal according to the fourth signaling and the fifth signaling, in accordance with the second preset rule.

[0124] In one implementation, the second preset rule includes:

[0125] The beam information set of the first channel and / or reference signal is determined based on the beam indication information in the fourth signaling that carries beam indication information and is active before the second channel and / or reference signal begins transmission, which is closest to the first symbol of the second channel and / or reference signal.

[0126] Based on the beam indication information in the fifth signaling carrying beam indication information that is active and closest to the first symbol of the first channel and / or reference signal before the first channel and / or reference signal begins transmission, the second beam information of the first channel and / or reference signal is determined in the beam information set of the first channel and / or reference signal.

[0127] Wherein, the second channel and / or reference signal is one of the following:

[0128] The first channel and / or reference signal;

[0129] The channel or reference signal carrying beam indication information and active, which is closest to the first symbol of the first channel and / or reference signal before the first channel and / or reference signal begins transmission.

[0130] In one implementation, determining the beam information set of the first channel and / or reference signal based on the beam indication information in the effective fourth signaling includes:

[0131] The first beam information set of the UE-dedicated channel and / or reference signal is determined based on the beam indication information in the fourth signaling that is closest to the first symbol of the second channel and / or reference signal and carries the first beam indication information and is in effect before the second channel and / or reference signal begins transmission; wherein the first beam indication information includes at least one of the following: joint TCI, DL TCI and UL TCI;

[0132] The second beam information set of the non-UE-dedicated and / or reference signal is determined based on the beam indication information in the fourth signaling carrying the second beam indication information that is active and closest to the first symbol of the second channel and / or reference signal before the second channel and / or reference signal begins transmission; wherein the second beam indication information includes at least one of the following: TCI state; spatial relation; joint TCI not associated with the target cell; DL TCI not associated with the target cell; UL TCI not associated with the target cell.

[0133] In one implementation, determining the second beam information of the first channel and / or reference signal in the beam information set of the first channel and / or reference signal based on the beam indication information in the effective fifth signaling includes at least one of the following:

[0134] When the first channel and / or reference signal is the UE-dedicated channel and / or reference signal, the second beam information is determined according to the TCI codepoint corresponding to the TCI field in the fifth signaling that is closest to and most active to the first symbol transmitted by the UE-dedicated channel and / or reference signal and corresponds to the TCI in the first beam information set.

[0135] When the first channel and / or reference signal is the DL UE-dedicated channel and / or reference signal, the second beam information is determined according to the DLTCI corresponding to the TCI codepoint in the fifth signaling that is closest to and most active to the first symbol transmitted by the DL UE-dedicated channel and / or reference signal in the first beam information set.

[0136] When the first channel and / or reference signal is the UL UE-dedicated channel and / or reference signal, the second beam information is determined according to the ULTCI corresponding to the TCI codepoint in the fifth signaling that is closest to and most active to the first symbol transmitted by the UL UE-dedicated channel and / or reference signal in the first beam information set.

[0137] When the first channel and / or reference signal is the DL non-UE-dedicated channel and / or reference signal, the second beam information or part of the second beam information is determined based on the beam information corresponding to the TCI codepoint in the fifth signaling that is closest to and most active to the first symbol transmitted by the DL non-UE-dedicated channel and / or reference signal in the second beam information set.

[0138] Furthermore, the fifth signaling message needs to meet the following conditions:

[0139] The transmission configuration indicator code point corresponding to the TCI field in the fifth signaling message corresponds to beam information in the second beam information set that includes at least one of the following:

[0140] TCI state, here TCI state is the R15 / 16 legacy TCI state;

[0141] Joint TCIs that are not directly or indirectly associated with the target cell;

[0142] DL TCIs that are not directly or indirectly associated with the target cell.

[0143] The following is an example of determining the second beam information under the second beam indication signaling mechanism.

[0144] The second beam indication signaling mechanism refers to the fact that both legacy TCI states and unified TCIs indicate beam information only through MAC CE+DCI. It is assumed that the correspondence between TCI codepoints activated by MAC CE and TCI states takes effect X ms 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. Considering the time for PDCCH decoding and hardware beam switching, the beam information determined by DCI only takes effect Y symbols after the last symbol of the PDCCH. Tables 2, 3, and 4 below show the formats of the three fourth signaling methods: MAC CE#1 signaling, MAC CE#2 signaling, and MAC CE#3 signaling.

[0152] Table 4

[0153] Specifically, MAC CE#1 carries beam indication information for the legacy TCI state; MAC CE#2 carries beam indication information for the unified TCI, and some TCI codepoints are associated with PCI#1, i.e., associated with the target cell; MAC CE# carries beam indication information for the unified TCI, and all TCI codepoints are associated with PCI#1. For separate TCIs, the first column in Tables 3 and 4 represents UL TCIs, and the second column represents DL TCIs.

[0154] like Figure 7 As shown, the arrival and activation times of each MAC CE and DCI are given. The second beam information of the first channel and / or reference signal is determined or updated according to the second preset rule in a manner that includes the following two methods:

[0155] Method 1: The TCI codepoint is determined based on the DCI closest to the first symbol of the first channel or reference signal before the first channel or reference signal begins transmission. The TCI state corresponding to the TCI codepoint is determined based on the beam information carried in the first MAC CE closest to the PDCCH carrying the DCI before the PDCCH carrying the DCI begins transmission.

[0156] like Figure 7 As shown, assuming the values ​​of the TCI fields in DCI#0, DCI#1, DCI#2, and DCI#3 are 0, 2, 5, and 7 respectively, the changes in the oscillation information of the channel and / or reference signal at different times under mode 1 are shown in Table 5 below.

[0160] Method 2: The TCI codepoint is determined based on the DCI closest to and active to the first symbol of the first channel or reference signal before the first channel or reference signal begins transmission. The TCI state contained in the TCI codepoint is determined based on the beam information carried in the TCI codepoints in the MAC CE closest to and active to the first symbol of the first channel or reference signal before the first channel or reference signal begins transmission.

[0161] like Figure 7 As shown in Table 6, assuming the values ​​of the TCI fields in DCI#0, DCI#1, DCI#2, and DCI#3 are 0, 2, 5, and 7 respectively, the changes in the oscillation information of the channel and / or reference signal at different times under mode 1 are shown in Table 6 below.

[0165] As can be seen from the technical solutions provided by the above embodiments of the present invention, the embodiments of this application, under the only MAC CE+DCI beam indication signaling mechanism, receive fourth and fifth signaling carrying beam indication information; the terminal determines or updates the second beam information of the first channel and / or reference signal according to the fourth and fifth signaling and a second preset rule, thereby enabling the terminal to accurately determine or update the channel and / or reference signal beam information under the only MAC CE+DCI beam indication signaling mechanism to achieve accurate transmission of the channel and / or reference signal and improve the reliability of data transmission.

[0166] Based on the above embodiments, further, as Figure 8 As shown, steps S210-S220 further include:

[0167] Step S810: The terminal receives the first signaling, the fourth signaling, and the fifth signaling carrying beam indication information.

[0168] It should be understood that the first signaling is the MAC CE signaling received under the first beam indication signaling mechanism, which is a MAC CE-only mechanism. The fourth and fifth signaling are the MAC CE signaling received as the fourth signaling and the DCI signaling received as the fifth signaling under the second beam indication signaling mechanism, which is a MAC CE+DCI beam indication signaling mechanism.

[0169] Furthermore, prior to step S810, the method may further include:

[0170] The terminal determines or switches the beam indication signaling mechanism based on the signaling containing beam indication information. When it determines that both the first beam indication signaling mechanism and the second beam indication signaling mechanism are used simultaneously, that is, different beam indication signaling mechanisms are used for different beam indication methods, for example, the first beam indication signaling mechanism is used for legacy TCI state and the second beam indication signaling mechanism is used for unified TCI, and then performs the following steps.

[0171] Step S820: The terminal determines or updates the third beam information of the first channel and / or reference signal according to the first signaling, the fourth signaling and the fifth signaling, and in accordance with the third preset rule.

[0172] In one implementation, the third preset rule includes at least one of the following:

[0173] 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 signaling and the first preset rule;

[0174] 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 fourth and fifth signaling and the second preset rule;

[0175] The third beam information is determined by the beam information whose effective time is closest to the target symbol of the first channel and / or reference signal from the first beam information and the second beam information.

[0176] The following is an example of determining the third beam information while simultaneously employing the first beam indication signaling mechanism and the second beam indication signaling mechanism.

[0177] Taking the legacy TCI state using a only MAC CE beam indication signaling mechanism and the unified TCI using a MAC CE+DCI beam indication signaling mechanism as an example. Figure 9As shown, the arrival and activation times of the first, fourth, and fifth signaling messages are given. It is assumed that MAC CE#1 is a TCI carrying legacy TCI state indication information, such as... Figure 4 As shown in Table 3 above, MAC CE#2 carries multiple TCI codepoints indicating unified TCI indication information, as indicated by MAC CE#1. DCI#0 determines one TCI codepoint from the multiple TCI codepoints indicated by MAC CE#2. According to the third preset rule, the beam information of different channels and / or reference signals at different times can be determined as follows. Taking the time periods [t4, t7] and [t7, A] as examples.

[0178] [t4, t7]: According to the first preset rule, based on the only MAC CE beam indication signaling mechanism, the effective beam information in the current time period can be determined as TCI state #1. While the multiple TCI codepoints carried by the MAC CE in the MAC CE+DCI beam indication signaling mechanism become effective at t5, the DCI signaling has not yet been detected or become effective; therefore, no unified TCI is effective. Combining the two mechanisms, the effective beam information in the current time period is determined to be TCI state #1. Therefore, the beam information of the DL non-UE-dedicated PDCCH in the current time period will be determined based on TCI state #1, while the beam information of other channels and / or reference signals will be determined based on the default beam mechanism.
