For example, in 5G systems, the base station is called a gNB. For convenience of description, in the embodiments of the present, the above-described devices that provide wireless communication functions for user equipment are collectively referred to as a network device.

[00114] As an example, said channel may include at least one, or any combination, of the following channels:

It should also be noted that the channels and reference signals listed above are purely examples and are not limiting of the present invention.

[00129] In embodiments of the present invention, a target common beam is used for communication between a user equipment and a network device. Depending on the direction of communication, these at least two types of communication may include channels and/or reference signals belonging to the uplink communication; channels and/or reference signals belonging to the downlink; or channels and/or reference signals, some of which are used for uplink communications and some of which are used for downlink communications. Below we will consider, accordingly, several of the possible implementations.

[00130] As a first possible implementation, the target common beam may be used to transmit at least two channels. For example, a target common beam may be used for both a PDSCH and a PDCCH, where the PDSCH may include all PDSCHs or only a portion of the PDSCHs, such as UE-specific PDSCHs; and the PDCCH may include all PDCCHs or only a portion of the PDCCHs, such as dedicated user equipment (UE) PDCCHs.

As another example, a target common beam may be used for both a PUSCH and a PUCCH, where the PUSCH may include all PUSCHs or only a portion of the PUSCHs, such as UE-specific PUSCHs, and the PDSCH may include all PDSCHs or only part of the PDSCHs, for example, dedicated user equipment (UE) PDSCHs. In the case where a target common beam is used for a PDSCH and a PDCCH, the target common beam may be called a target common beam (DL common beam). In the case where a target common beam is used for a PUSCH and a PUCCH, the target common beam may be called an uplink target common beam (UL common beam). In the case where a target common beam is used for a PUSCH and a PDSCH, the target common beam may be called a common beam, that is, it may be used for both uplink and downlink channels.

[00131] As a second possible implementation, the target common beam may be used to transmit at least two reference signals. These applied at least two reference signals may both belong to a downlink reference signal, or may both belong to an uplink reference signal, or may be a combination of a downlink reference signal and an uplink reference signal, without limitation. implementation of the present invention in this regard. For example, the downlink reference signal may include at least one of the following: an SSB signal, CSI-RS, PRS, TRS, or DMRS. Alternatively, as another example, the uplink reference signal may include at least one of the following: an SRS signal or a DMRS signal. In the case of some reference signals, such as CSI-RS, the reference signal may include all CSI-RS signals; or instead of all CSI-RS signals, the reference signal may include one or more CSI-RS signals intended for at least one purpose, for example, at least one of the following: channel state information measurement, beam measurement, loss estimation transmission or location measurement. As another example, the SRS signal may include all SRS signals; or instead of all SRS signals, the SRS signal may include one or more SRS signals intended for at least one purpose, for example, at least one of the following: non-codebook based channel state information measurement, beam measurement, switching antennas or position measurement.

[00132] As a third possible implementation, the target common beam may be used to transmit at least one reference signal and at least one channel. For example, the target common beam may be used to transmit a PDSCH and a downlink reference signal, wherein the downlink reference signal may include at least one of an SSB, CSI-RS, PRS, TRS, or DMRS signal. Alternatively, as another example, the target common beam may be used to transmit a PUSCH and an uplink reference signal, wherein the uplink reference signal may include at least one of an SRS signal or a DMRS signal. Similarly, the PDSCH in this case may include all PDSCHs or only part of the PDSCHs, for example, dedicated user equipment (UE) PDSCHs; the PUSCH in this case may include all PUSCHs or only part of the PUSCHs, for example, dedicated PUSCHs to a specific user equipment (UE); and the reference signal in this case, for example a CSI-RS or SRS signal, may include CSI-RS or SRS signals intended for any purpose or intended for at least one purpose.

[00133] It should be noted that the downlink channels, uplink channels, downlink reference signals and uplink reference signals mentioned above are for illustration purposes only. Specific implementations are not limited to these several types of channels and reference signals, and they do not limit the scope of the present invention.

[00134] In one possible implementation of embodiments of the present invention, the first indication information further includes indication information of the at least two communication types. That is, the indication information indicates specific types of these at least two communication types specified for a user equipment (UE) to communicate with a network device using a target common beam. For example, the indication information may indicate that the communication carried out between the user equipment and the network device using the target common beam is PDSCH transmission and PDCCH transmission. However, specific implementations of the at least two types of communication mentioned above are described above and will not be presented here again.

[00135] In embodiments of the present invention, the target common beam may be a single beam or may include multiple beams, without limiting the embodiments of the present invention in this regard.

[00136] In the case where a target common beam includes multiple beams, a corresponding target common beam related to each transmission and reception point (TRP), or a corresponding target common beam related to each management resource set pool index (CORESET pool index) , must be determined according to the first indication information transmitted by the network device, that is, the target TCI state index in the first indication information must correspond to the TRP index or the CORESET pool index.

[00137] In embodiments of the present invention, the first indication information is transmitted to the user equipment (UE) by the network device, whereby after receiving the first indication information transmitted by the network device, the user equipment (UE) communicates with the network device using the target common beam for at least two channels or at least two reference signals, or at least one reference signal and at least one channel. By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communications, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the amount of transmission service information.

[00138] FIG. 2 is a block diagram of another beam indicating method proposed in embodiments of the present invention, which is used in a user equipment (UE).

[00139] Using the beam indicating method shown in FIG. 2, a method for specifying a target common beam is illustrated. In accordance with the illustration of FIG. 2, the method includes the steps described below.

[00140] At step 201, the target common index, or combination of indices, of the transmission configuration indicator (TCI) state is received.

[00141] For a description of the user equipment (UE) and network device shown in the drawing, refer to the above discussion of any of the previous embodiments of the present invention. It will not be repeated here.

[00142] In embodiments of the present invention, the first indication information received by the user equipment includes a target common index, or combination of indexes, of transmission configuration indicator (TCI) states transmitted by the network device. A combination of target common TCI status indexes can be identified using a combination identifier. For example, the values 01 and 02 can indicate, respectively, different combinations of indices. Alternatively, indicating different combinations of indices can be done using different code points. For example, the three-bit code points 000 and 001 can indicate different combinations of indices, respectively. Various index combinations contain one or more TCI status indexes. One or more target common TCI status indexes may be present. Each target common TCI state index corresponds to one or more reference signals (RS), with each reference signal used to indicate a target uplink common beam and/or a target downlink common beam.

[00143] In embodiments of the present invention, the target common state TCI includes at least one of the following: a target common state TCI of the downlink, a target common state of the uplink TCI, or a target common state of the uplink and downlink TCI.

[00144] It is to be understood that the reference signal corresponding to the target common downlink TCI, eg, the RS signal, is not used to indicate the target common uplink channel beam or the uplink reference signal; and a reference signal corresponding to the target uplink common TCI status index, for example, an RS signal, is not used to indicate the target common downlink channel beam or the downlink reference signal. One or more reference signals corresponding to the target common uplink and downlink TCI, eg, one or more RS signals, may indicate the target uplink common beam or the target uplink common beam simultaneously. For example, indicating a target uplink common beam and a target downlink common beam may be performed using a single reference signal (RS) or using multiple reference signals (RS), respectively.

[00145] In one implementation, a network device may configure a mapping between target common state indices TCIs and reference signals (RS) for user equipment (UE) using radio resource control (RRC) signaling. After receiving the target TCI state index, the user equipment (UE) requests said mapping between the target common TCI state indices and reference signals (RS) according to the target TCI state index, and obtains a reference RS signal corresponding to the target TCI state index. Thus, the user equipment (UE) determines the corresponding beam according to the reference signal RS. Optionally, the mapping between the TCI status indices and the RC reference signals may be in the form of a TCL table or other form, and the TCI table mapping is provided by way of example for illustration purposes only. The TCI table may contain TCI state indices (eg, TCI state IDs), reference signal indices (reference signal ID, RS ID), or similar information.

[00146] It should be noted that when a combination of target common state indexes TCI is obtained, a plurality of target common state indexes TCI thereof is determined according to the correspondence relationship between the identifiers of the index combinations, or bit mapped code points, and the index combinations, wherein the corresponding target common beam determined according to a preconfigured correspondence between the TCI status indices and the RS reference signal indices.

[00147] As one possible implementation, the TCI status index transmitted by the network device may indicate either a target uplink common beam or a target downlink common beam. That is, the target uplink common state TCI is used to indicate the target uplink common beam, and the target downlink common state TCI is used to indicate the target downlink common beam.

[00148] As yet another possible implementation, a target common TCI transmitted by a network device may be used to indicate a target uplink common beam and a target downlink common beam. In one implementation, the target common TCI transmitted by the network device may be used to indicate the target uplink common beam and the target downlink common beam. In one implementation, the target common state index TCI transmitted by the network device may indicate a corresponding reference signal for each TRP, wherein said reference signal RS may indicate a target uplink common beam or a target downlink common beam. In yet another implementation, the target common TCI transmitted by the network device may indicate two corresponding reference signals for each TRP, wherein one of the two reference signals is used to indicate the target common uplink beam and the second is used to indicate the target common beam. downlink beam.

[00149] It should be noted that the target common state index TCI corresponds to one transmit and receive point (TRP) index or one CORESET pool index. That is, the target common TCI is universal for multiple transmissions with a single TRP, while different target common TCIs are used for different TRPs; and the target common state index TCI is universal for multiple transmissions with one CORESET pool index, while different target common state indexes TCI are used for different CORESET pool indexes.

[00150] It should be noted that in one embodiment of the present invention, in the case of one TRP, the common beam found will be the beam corresponding to that TRP. In yet another embodiment of the present invention, in the case of multiple TRPs, different TRPs will have corresponding target common TCIs, each target common TCI having a corresponding reference RS signal, and according to the correspondence between the target common beam and the RS signal, a target common beam corresponding to the desired TPR can be determined.

[00151] At step 202, according to the target common TCI state index or combination of indices, the target common beam is determined.

[00152] The index combination includes a plurality of TCI status indexes, with each of the plurality of TCI status indexes corresponding to a different TRP point.

[00153] In one implementation, a network device may pre-configure a mapping between target common state indices TCIs and reference signals (RS) for user equipment (UE) using upper layer signaling, such as radio resource control (RRC) signaling or control element signaling ( CE) media access control (MAC) layer. According to the predetermined mapping, the user equipment (UE) can determine the corresponding target common beam according to the target common TCI status index dynamically indicated by the network device.

[00154] At step 203, at least two types of communication with the network device are performed using a target common beam. Communication includes communication of a channel and/or a reference signal.

[00155] In embodiments of the present invention, step 203 may be performed using any of the implementations described in various embodiments of the present invention, which will not be repeated here and which do not limit the embodiments of the present invention.

[00156] In embodiments of the present invention, the first common beam target indication information is transmitted to the user equipment (UE) by the network device, whereby after receiving the first common beam target indication information transmitted by the network device, the user equipment (UE) communicates with a network device using a target common beam for at least two channels or at least two reference signals, or at least one reference signal and at least one channel. By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communications, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the amount of transmission service information.

[00157] FIG. 3 is a block diagram of yet another beam indicating method proposed in embodiments of the present invention. The proposed method is executed in a user equipment (UE).

[00158] In embodiments of the present invention, a possible method for transmitting first common beam target indication information is provided. In accordance with the illustration of FIG. 3, the method includes the steps described below.

[00159] At step 301, media access layer control element signaling (MAC CE signaling) is received from the network device. The MAC CE signaling contains second indication information for activating one or more TCI status indexes, with one TCI status index corresponding to one TRP index or one CORESET pool index.

[00160] For a description of the user equipment (UE) and network device shown in the drawing, refer to the above discussion of any of the previous embodiments of the present invention. It will not be repeated here.

[00161] MAC CE signaling includes an indication bit that stores second indication information for activating one or more TCI status indexes. That is, the second indication information indicates the need to activate one or more TCI status indices.

[00162] Optionally, the MAC CE signaling has a corresponding indication bit for each TCI status index, whereby the user equipment (UE) determines the corresponding TCI status index according to the second indication information in the indication bit, wherein one TCI status index corresponds to one TRP index or one pool index CORESET.

[00163] It should be noted that said beam may be an uplink beam, an uplink beam, or a common uplink and downlink beam. The one or more activated beams may include at least one downlink beam and/or at least one downlink beam, or at least one common uplink and downlink beam. Embodiments of the present invention are not limited in the number of activated beams .

[00164] At step 302, first indication information is determined according to one or more TCI status indexes activated by the second indication information.

[00165] The first indication information is used to indicate the target common beam.

[00166] In embodiments of the present invention, one TCI status index corresponds to one TRP index or one CORESET pool index.

[00167] In one possible scenario, one TCI status index is activated by the second indication information for one TRP index or one CORESET pool index, whereby the first indication information is determined to be said one TCI status index activated by the second indication information . For example, one TCI may have one TCI status activated for one TRP, then the TCI status index corresponding to that TRP will be the activated TCI status index. In one example, the activated TCI may correspond to a target downlink common TCI, in which case the reference signal corresponding to the activated TCI indicates the target downlink common beam, and the target downlink common beam for a given TRP will be a downlink beam indicated by a reference signal corresponding to said TCI status index. In yet another example, the activated TCI may correspond to a target uplink common TCI, in which case the reference signal corresponding to the activated TCI indicates the target uplink common beam, and the target uplink common beam for a given TRP there will be an uplink beam that is indicated by a reference signal corresponding to said TCI status index. In yet another example, the activated TCI status index may correspond to the target common TCI status index, in which case the reference signal corresponding to the activated TCI status index indicates the target uplink common beam and the target downlink common beam, and the target uplink common beam communication and the target common downlink beam for a given TRP will be the uplink beam and the downlink beam, which are indicated by a reference signal corresponding to said TCI status index.

[00168] In one possible scenario, the second indication information activates a plurality of TCI status indexes for one TRP index or one CORESET pool index, that is, it is necessary to determine, as the first indication information, a target common index, or combination of indexes, of the TCI status according to the corresponding TRP index or CORESET pool index from this set of TCI status indexes. In one implementation, a first signaling with downlink control information (DCI) is received from a network device. The first DCI signaling contains first indication information, wherein the first indication information includes one target common TCI state index, or combination of indices, from a plurality of TCI state indices activated by the second indication information.

[00169] It should be noted that said index combination contains a plurality of common TCI status indices, with different TCI status indices corresponding to different TRPs or different CORESET pool indices.

[00170] At step 303, at least two types of communication with the network device are performed using a target common beam. Communication includes communication of a channel and/or a reference signal.

[00171] In embodiments of the present invention, step 303 may be performed by any of the implementations described in various embodiments of the present invention, which will not be repeated herein and which do not limit the embodiments of the present invention.

[00172] In embodiments of the present invention, the first common beam target indication information is transmitted to the user equipment (UE) by the network device, whereby after receiving the first common beam target indication information transmitted by the network device, the user equipment (UE) communicates with a network device using a target common beam for at least two channels or at least two reference signals, or at least one reference signal and at least one channel. By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communications, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the amount of transmission service information.

[00173] FIG. 4 is a block diagram of yet another beam indicating method proposed in embodiments of the present invention. The proposed method is executed in a user equipment (UE).

[00174] In embodiments of the present invention, a possible method for transmitting first common beam target indication information is provided. In accordance with the illustration of FIG. 4, the method includes the steps described below.

[00175] At step 401, a first signaling with downlink control information (DCI) is received from the network device.

[00176] For a description of the user equipment (UE) and network device shown in the drawing, refer to the above discussion of any of the previous embodiments of the present invention. It will not be repeated here.

[00177] The first DCI signaling includes first target common beam indication information. That is, the target common index, or combination of indices, TCI states, and resource configuration information are in different DCI signaling, wherein in the first DCI signaling is the target common index, or combination of indices, TCI states, that is, the first information instructions.

[00178] The first DCI signaling may be based on a single TRP or multiple TRPs, without limiting this embodiment of the invention in this regard.

[00179] In one possible implementation of embodiments of the present invention, a user equipment (UE) uses one or more receive beams to receive one or more DCI signaling transmissions, that is, a network device uses one or more TRPs to perform one or more DCI transmissions - signaling, with each TRP corresponding to a separate beam, which avoids blocking signal transmission and improves communication quality to ensure the reception of the first DCI signaling.

[00180] At step 402, first hybrid automatic repeat request (HARQ) feedback information is transmitted to the network device.

[00181] The first HARQ feedback information is used to indicate to the network device whether the first DCI signaling was successfully received.

[00182] The HARQ feedback resource used to transmit the first HARQ feedback information is configured using the first DCI signaling or is set by default.

[00183] In one possible scenario, the first DCI signaling is transmitted, by the network device, once, and accordingly, from the user equipment (UE) point of view, one or more candidate PUCCH/PUSCH resources may be present for transmitting the first feedback information HARQ.

[00184] In yet another possible scenario, the first DCI signaling is transmitted, by the network device, multiple times, and accordingly, from the user equipment (UE) point of view, one or more candidate PUCCH/PUSCH resources may be present for transmitting the first information HARQ feedback.

[00185] Optionally, the user equipment (UE) may transmit first HARQ feedback information whenever it receives the first DCI signaling.

[00186] Alternatively, the network device may periodically transmit the first DCI signaling at N transmission instants respectively, and thus the user equipment (UE) may be configured to use L candidate PUCCH/PUSCH resources to transmit the first HARQ feedback information, where L is less than or equal to N, some of the L candidate PUCCH/PUSCH resources precede the end of the N transmission times, and some of them are located after the end of the N transmission times. In case of correct reception, by the user equipment (UE), of the first DCI signaling before the N transmission times, the user equipment (UE) may select one of the PUCCH/PUSCH candidate resources to transmit HARQ feedback information up to the N transmission times. In the case of the user equipment (UE) correctly receiving the first DCI signaling after the end of the N transmission times, the UE may select another candidate PUCCH/PUSCH resource for transmitting the HARQ feedback information after the end of the N transmission times.

[00187] Alternatively, the network device may periodically transmit the first DCI signaling at N transmission instants respectively, and thus the user equipment (UE) may be configured to use one PUCCH/PUSCH candidate resource to transmit the first HARQ feedback information, at herein, the user equipment (UE) may transmit the first HARQ feedback information after the completion of the N transmission instants.

[00188] In this case, during subsequent communication of the user equipment (UE) with the network device, the user equipment (UE) uses a target common beam to perform at least two types of communication with the network device. Communication includes communication of a channel and/or a reference signal.

[00189] In one embodiment of the present invention, the transmit beam for transmitting the second HARQ feedback information is a transmit beam corresponding to the target common beam corresponding to the target common TCI status index or combination of indices in the first DCI signaling.

[00190] In yet another embodiment of the present invention, the transmit beam for transmitting the second HARQ feedback information is a transmit beam corresponding to the receive beam for receiving the first DCI signaling.

[00191] At step 403, the second DCI signaling transmitted by the network device is received using the target common beam on the physical downlink control channel (PDCCH).

[00192] In embodiments of the present invention, for convenience of description, DCI signaling containing communication resource configuration information is referred to as second DCI signaling.

[00193] The second DCI signaling contains resource configuration information for configuring a communication resource for a reference signal, a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and/or or physical downlink shared channel (PDSCH).

[00194] The configured reference signal may include, but is not limited to, at least one of the following signals:

[00195] channel state information reference signal, CSI-RS;

[00196] synchronization signal block and Strategic Missile Forces, SSB;

[00197] demodulation reference signal, DMRS;

[00198] position reference signal, PRS;

[00199] tracking reference signal, TRS; or

[00200] SRS sounding reference signal.

[00201] The reference signals listed above can be used in various scenarios, for example, for beam measurement, channel state information measurement, propagation loss estimation, antenna switching, position measurement, channel estimation or demodulation timing tracking, and the like. , however, in embodiments of the present invention they will not be listed. Specific implementations of the present invention are not limited to the above several types of reference signals, nor do the mentioned types of reference signals limit the scope of the present invention.

[00202] It should be understood that the second DCI signaling may be the DCI signaling that is transmitted first after the first DCI signaling is transmitted. The time interval between the first DCI signaling and the second DCI signaling is sufficient for the user equipment (UE) to return HARQ feedback to the network device, that is, the time interval is sufficient for the user equipment to decode the received first DCI signaling and return HARQ to the network device .

[00203] In embodiments of the present invention, the first common beam target indication information is transmitted to the user equipment (UE) by the network device, whereby after receiving the first common beam target indication information transmitted by the network device, the user equipment (UE) communicates with a network device using a target common beam for at least two channels or at least two reference signals, or at least one reference signal and at least one channel. By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communications, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the amount of transmission service information.

[00204] FIG. 5 is a block diagram of yet another beam indicating method proposed in embodiments of the present invention. The proposed method is executed in a user equipment (UE).

[00205] In embodiments of the present invention, a possible method for transmitting first common beam target indication information is provided. In accordance with the illustration of FIG. 5, the method includes the steps described below.

[00206] At step 501, the first DCI signaling sent by the network device is received.

[00207] For a description of the user equipment (UE) and network device shown in the drawing, refer to the above discussion of any of the previous embodiments of the present invention. It will not be repeated here.

[00208] The first DCI signaling includes first indication information and contains resource configuration information for configuring a communication resource for at least one of a reference signal, a PRACH, a PUSCH, a PUCCH, or a PDSCH.

[00209] In one possible implementation, the first DCI signaling contains resource configuration information for a downlink communication resource, wherein the first DCI signaling is DCI signaling that is used for scheduling downlink resources. The first DCI signaling may take the form of predefined DCI signaling, for example, DCI information format 10, 11 or 12, newly defined DCI signaling, or other DCI signaling that will not be listed in embodiments of the present invention, wherein the present the invention is not limited in this regard.

[00210] In yet another possible implementation, the first DCI signaling contains resource configuration information for an uplink communication resource, wherein the first DCI signaling is DCI signaling that is used for scheduling uplink resources. The first DCI signaling may take the form of predefined DCI signaling, for example, format 0_0, 0_1 or 0_2 DCI information, newly defined DCI signaling, or other DCI signaling that will not be listed individually in embodiments of the present invention, when The present invention is not limited in this regard.

[00211] In a third possible implementation, the first DCI signaling contains resource configuration information for uplink and downlink communication resources, wherein the first DCI signaling is DCI signaling that is used for scheduling uplink and downlink resources.

[00212] The first DCI signaling may be DCI signaling for resource configuration for a single TRP or for multiple TRPs, without limiting the present embodiment in this regard.

[00213] At step 502, second HARQ feedback information is transmitted to the network device.

[00214] In embodiments of the present invention, in the case where the HARQ feedback resource is configured, the second HARQ feedback information is transmitted to the network device.

[00215] The user equipment (UE) may use the same beam that was used to transmit the first DCI signaling to transmit the second HARQ feedback information to the network device, or use the target common beam indicated by the first indication information contained in the first DCI signaling, for transmitting the second HARQ feedback information to the network device, without limiting the present invention in this regard.

[00216] In one possible implementation, if a network device schedules two HARQ feedback resources using the first DCI signaling, or if the user equipment (UE) is pre-configured to use two HARQ feedback resources, the second HARQ feedback information includes: the first feedback information configured to return information about whether the first DCI signaling has been successfully received, and second feedback information configured to return information about whether the PDSCH and/or downlink reference signal configured to using the first DCI signaling.

[00217] In yet another possible implementation, if a network device schedules one HARQ feedback resource using first DCI signaling, or if the user equipment (UE) is pre-configured to use the HARQ feedback resource, the second HARQ feedback information includes: the first feedback information and second feedback information for which said HARQ feedback resource is shared.

[00218] In one implementation of embodiments of the present invention, the HARQ feedback resources used to transmit the first feedback information and/or the second feedback information are configured with the first DCI signaling or are set by default.

[00219] In one implementation of embodiments of the present invention, the HARQ feedback resources used to transmit the first feedback information and/or the second feedback information are identical HARQ feedback resources and/or different HARQ feedback resources.

[00220] In one example, when the HARQ feedback resources used to transmit the first feedback information and/or the second feedback information are identical HARQ feedback resources and/or different HARQ feedback resources, the first feedback information and/or or the second feedback information corresponds to the same or different bits in one HARQ feedback resource.

[00221] In one possible scenario, the first DCI signaling is transmitted, by the network device, once, and accordingly, from the user equipment (UE) point of view, one or more candidate PUCCH/PUSCH resources may be present for transmitting the second feedback information HARQ.

[00222] In yet another possible scenario, the first DCI signaling is transmitted, by the network device, multiple times, and accordingly, from the user equipment (UE) point of view, one or more candidate PUCCH/PUSCH resources may be present for transmitting the second information HARQ feedback. Optionally, the user equipment (UE) may transmit second HARQ feedback information whenever it receives the first DCI signaling. Alternatively, the network device may periodically transmit the first DCI signaling at N transmission instants, respectively, and thus the user equipment (UE) may be configured to use L PUCCH/PUSCH candidate resources to transmit the first HARQ feedback information, where L is less than or is N, a portion of the L candidate PUCCH/PUSCH resources precede the end of the N transmission instants, and a portion of them are located after the end of the N transmission instants. In case of correct reception, by the user equipment (UE), of the first DCI signaling before the N transmission times, the user equipment (UE) may select one of the PUCCH/PUSCH candidate resources for transmitting the second HARQ feedback information up to the N transmission times. In case of correct reception, by the user equipment (UE), of the first DCI signaling at or after the end of the N transmission instants, the user equipment (UE) may select a candidate PUCCH/PUSCH resource to transmit the second HARQ feedback information after the end of the N transmission instants. . Alternatively, the network device may periodically transmit the first DCI signaling at N transmission times, respectively, and thus, the user equipment (UE) may be configured to use one PUCCH/PUSCH candidate resource to transmit the first HARQ feedback information, wherein the user equipment the equipment (UE) may transmit second HARQ feedback information after the N transmission instants.

[00223] In one embodiment of the present invention, the transmit beam for transmitting the second HARQ feedback information is a transmit beam corresponding to the target common beam corresponding to the target common TCI status index or combination of indices in the first DCI signaling.

[00224] In one embodiment of the present invention, the transmit beam for transmitting the second HARQ feedback information is a transmit beam corresponding to the receive beam for receiving the first DCI signaling.

[00225] The step is to communicate with a network device using a communication resource configured in accordance with the resource configuration information contained in the first DCI signaling.

[00226] In embodiments of the present invention, in a case where HARQ feedback information indicating whether the first DCI signaling has been successfully received is not transmitted separately, the network device determines whether the user equipment (UE) has received the first DCI signaling, that is, whether the network device has completed configuration, according to whether the user equipment (UE) uses the configured communication resource to communicate with the network device.

[00227] In one implementation of embodiments of the present invention, in the case where the time interval between transmission from the user equipment (UE) and reception of the first DCI signaling is less than a threshold value, the same beam as for DCI signaling is used for communication.

[00228] In yet another implementation of embodiments of the present invention, in the case where the time interval between transmission from the user equipment (UE) and reception of the first DCI signaling is greater than or equal to a threshold value, a target common beam corresponding to the target common index is used for communication TCI states in the first DCI signaling.

[00229] In embodiments of the present invention, the threshold value 503 is set in the user equipment by default. In one possible implementation, said threshold value is notified by a network device. In yet another possible implementation, the threshold determination may be performed according to the previous communication time, without limiting the embodiments of the present invention in this regard.

[00230] In one example, said threshold value may be notified by a network device.

[00231] In one possible implementation, the user equipment (UE) transmits a reference time to a network device, wherein the reference time is configured for use by the network device to determine said threshold value. The reference time includes a time for decoding the first DCI signaling, a time for HARQ feedback corresponding to the first DCI signaling, and a time for beam switching; or the reference time includes a HARQ feedback time corresponding to the first DCI signaling and a time for beam switching. Accordingly, the user equipment (UE) determines that the first DCI signaling is decoding. HARQ feedback and beam switching may be performed within the reference time, or that HARQ feedback and beam switching may be performed within the reference time.

[00232] In one possible implementation, the threshold value determined by the network device is greater than or equal to the reference time.

[00233] Embodiments of the present invention are discussed in detail based on examples in which communication includes uplink transmission from a user equipment to a network device and/or downlink reception by the user equipment.

[00234] In embodiments of the present invention, in the case where the HARQ feedback resource indicating whether the first DCI signaling has been successfully received is not separately configured, the network device determines whether the user equipment (UE) has received the first DCI signaling, that is, whether the network device has completed configuration, according to whether the user equipment (UE) uses the configured communication resource for downlink transmissions to the network device; or the network device uses the configured communication resource for downlink transmission to the user equipment (UE) and determines whether the user equipment (UE) has successfully received and decoded the first DCI signaling according to the HARQ feedback information that is returned by the user equipment (UE), and indicates whether the user equipment (UE) successfully received and decoded the downlink transmission.

[00235] It should be noted that in the case where the time interval between the uplink communication and/or downlink communication and the first DCI signaling is less than a threshold value, for the uplink communication and/or downlink communication communications use the same beam as for the first DCI signaling. In the case where the time interval between the uplink transmission and/or downlink transmission and the first DCI signaling is greater than or equal to the threshold value, the same beam is used for the uplink transmission and/or downlink transmission. same as the target common beam corresponding to the target common TCI status index or combination of indices in the first DCI signaling. The threshold value is at least one of the following: the time required for the user equipment (UE) to return, to the network device, information about whether the first DCI signaling was correctly received, or the time for beam switching. The time threshold may be determined by an agreement between the user equipment (UE) and the network device.

[00236] After the network device determines that the user equipment (UE) has correctly received the first DCI signaling, in subsequent communications between the user equipment (UE) and the network device, the user equipment (UE) may use the target common beam to implement at least at least two types of communication with the network device so as to use the target common beam to perform uplink and/or downlink communication with the network device.

[00237] At step 504, at least two types of communication with the network device are performed using a target common beam.

[00238] The time is counted from the moment when the first DCI signaling is received, and at least two types of communication are performed if it is determined that the counted time has reached the above-mentioned threshold, that is, channel and/or reference signal communication at the above-mentioned at least two types of communication are performed using a network device using a target common beam, which reduces the amount of signaling overhead.

[00239] In embodiments of the present invention, step 503 may be performed using any of the implementations described in various embodiments of the present invention, which will not be repeated herein and which do not limit the embodiments of the present invention.

[00240] In embodiments of the present invention, the first common beam target indication information is transmitted to the user equipment (UE) by the network device, whereby after receiving the first common beam target indication information transmitted by the network device, the user equipment (UE) communicates with a network device using a target common beam for at least two channels or at least two reference signals, or at least one reference signal and at least one channel. By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communication, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the volume transmitted service information.

[00241] Embodiments of the present invention provide a possible beam pointing and beam switching method. In embodiments of the present invention, as one possible implementation, the user equipment may also receive third indication information transmitted by the network device, wherein the third indication information is configured to indicate to the user equipment (UE) to apply the target common beam or dedicated beam to implement the said at least two types of communication.

[00242] In one implementation, the third indication information received by the user equipment may be received before the user equipment receives the first indication information, causing the user equipment to decide whether to use the target common beam or to use a dedicated beam to carry out the aforementioned at least two types of communication according to the third indication information. In one example, if a decision is made to use a dedicated beam to carry out at least two types of communication, the two types of communication are carried out in accordance with the dedicated beam. Different signaling is used to indicate a dedicated beam for each transmission. In yet another example, if it is decided to use a target common beam to perform at least two types of communication, the target common beam used for communication is further determined according to the received first indication information. For detailed information regarding this, reference may be made to any of the above-described implementations of any of the embodiments of the present invention and will not be repeated here.

[00243] In yet another implementation, the third indication information received by the user equipment may be received after the user equipment receives the first indication information, wherein the network device determines that the target common beam should be switched to a dedicated beam according to the third indication information , and the dedicated beam must be separately indicated by means of separate signaling for each channel and/or each reference signal. In one possible application scenario, a network device may need to switch a given channel or reference signal to a dedicated beam, that is, only the indication information for that dedicated dedicated beam corresponding to said channel or reference signal may be transmitted, while the remaining channels and reference signals signals that have not received the dedicated beam indication information continue to use the target common beam. In yet another possible application scenario, the network device may switch each channel and/or reference signal currently using a target common beam to a dedicated beam and transmit dedicated beam indication information for each channel or reference signal, respectively.

[00249] The first indication information may be contained in control signaling, such as radio resource control (RRC) signaling, media access control (MAC) layer control element (CE) signaling, or MAC CE signaling for short, signaling with downstream control information communication line (DCI), or a combination of at least two of these signalings. In embodiments of the present invention, there is no limitation on the method of transmitting the first common beam target indication information.

[00250] As an example, said channel may include at least one, or any combination, of the following channels:

[00251] physical downlink control channel, PDCCH;

[00263] SRS sounding reference signal.

[00264] The reference signals listed above can be used in various scenarios, for example, for beam measurement, channel state information measurement, propagation loss estimation, antenna switching, position measurement, channel estimation or demodulation timing tracking, and the like. , however, in embodiments of the present invention they will not be listed separately. The channels and reference signals listed above are purely examples and do not limit the present invention.

[00265] In embodiments of the present invention, a target common beam is used for communication between a user equipment and a network device. Depending on the direction of communication, these at least two types of communication may include channels and/or reference signals belonging to the uplink communication; channels and/or reference signals belonging to the downlink; or channels and/or reference signals, some of which are used for uplink communications and some of which are used for downlink communications. Below we will consider, accordingly, several of the possible implementations.

[00266] As a first possible implementation, the target common beam may be used to transmit at least two channels. For example, a target common beam may be used for both a PDSCH and a PDCCH, where the PDSCH may include all PDSCHs or only a portion of the PDSCHs, such as UE-specific PDSCHs; and the PDCCH may include all PDCCHs or only a portion of the PDCCHs, such as dedicated user equipment (UE) PDCCHs. Alternatively, as another example, a target common beam may be used for both a PUSCH and a PUCCH, wherein the PUSCH may include all PUSCHs or only a portion of the PUSCHs, such as UE-specific PUSCHs and the The PUCCH may include all PUCCHs or may include only a portion of the PUCCHs, such as dedicated user equipment (UE) PUCCHs. As another example, a target common beam may be used for both a PUSCH and a PUCCH, where the PUSCH may include all PUSCHs or only a portion of the PUSCHs, such as UE-specific PUSCHs, and the PDSCH may include all PDSCHs or only part of the PDSCHs, for example, dedicated user equipment (UE) PDSCHs. In the case where a target common beam is used for a PDSCH and a PDCCH, the target common beam may be called a target common beam (DL common beam). In the case where a target common beam is used for a PUSCH and a PUCCH, the target common beam may be called an uplink target common beam (UL common beam). In the case where a target common beam is used for a PUSCH and a PDSCH, the target common beam may be called a common beam, that is, it may be used for both uplink and downlink channels.

[00267] As a second possible implementation, the target common beam may be used to transmit at least two reference signals. These applied at least two reference signals may both belong to a downlink reference signal, or may both belong to an uplink reference signal, or may be a combination of a downlink reference signal and an uplink reference signal, without limitation. implementation of the present invention in this regard. For example, the downlink reference signal may include at least one of the following: an SSB signal, CSI-RS, PRS, TRS, or DMRS. Alternatively, as another example, the uplink reference signal may include at least one of the following: an SRS signal or a DMRS signal. In the case of some reference signals, such as CSI-RS, the reference signal may include all CSI-RS signals; or instead of all CSI-RS signals, the reference signal may include one or more CSI-RS signals intended for at least one purpose, for example, at least one of the following: channel state information measurement, beam measurement, loss estimation transmission or location measurement. As another example, the SRS signal may include all SRS signals; or instead of all SRS signals, the SRS signal may include one or more SRS signals intended for at least one purpose, for example, at least one of the following: non-codebook based channel state information measurement, beam measurement, switching antennas or location measurement.

[00268] As a third possible implementation, the target common beam may be used to transmit at least one reference signal and at least one channel. For example, the target common beam may be used to transmit a PDSCH and a downlink reference signal, wherein the downlink reference signal may include at least one of an SSB, CSI-RS, PRS, TRS, or DMRS signal. Alternatively, as another example, the target common beam may be used to transmit a PUSCH and an uplink reference signal, wherein the uplink reference signal may include at least one of an SRS signal or a DMRS signal. Similarly, the PDSCH in this case may include all PDSCHs or only part of the PDSCHs, for example, dedicated user equipment (UE) PDSCHs; the PUSCH in this case may include all PUSCHs or only part of the PUSCHs, for example, dedicated PUSCHs to a specific user equipment (UE); and the reference signal in this case, for example a CSI-RS or SRS signal, may include CSI-RS or SRS signals intended for any purpose or intended for at least one purpose.

[00269] It should be noted that the downlink channels, uplink channels, downlink reference signals and uplink reference signals mentioned above are for illustration purposes only. Specific implementations are not limited to these several types of channels and reference signals, and they do not limit the scope of the present invention.

[00270] In one possible implementation of embodiments of the present invention, the first indication information further includes indication information of the at least two communication types. That is, the indication information indicates specific types of the at least two communication types specified for a user equipment (UE) to communicate with a network device using a target common beam. For example, the indication information may indicate that the communication carried out between the user equipment and the network device using the target common beam is PDSCH transmission and PDCCH transmission. However, specific implementations of the at least two types of communication mentioned above are described above and will not be presented here again.

[00271] In embodiments of the present invention, the target common beam may be a single beam or may include multiple beams, without limiting the embodiments of the present invention in this regard.

[00272] In the case where the target common beam includes multiple beams, the corresponding target common beam associated with each TRP or the corresponding target common beam associated with each CORESET pool index needs to be determined according to the first indication information transmitted by the network device, then there is a target TCI status index in the first indication information that must match the TRP index or the CORESET pool index.

[00273] In embodiments of the present invention, the first indication information is transmitted to the user equipment (UE) by the network device, whereby after receiving the first indication information transmitted by the network device, the user equipment (UE) communicates with the network device using the target common beam for at least two channels or at least two reference signals, or at least one reference signal and at least one channel. By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communication, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the amount of transmission service information.

[00274] FIG. 7 is a block diagram of another beam indicating method proposed in embodiments of the present invention, which is used in user equipment.

[00275] Using the beam indicating method shown in FIG. 7, indicating a target common beam is illustrated. In accordance with the illustration of FIG. 7, the method includes the steps described below.

[00276] At step 701, the target common TCI state index, or combination of indices, is transmitted to the user equipment (UE), so that the user equipment (UE) can determine the target common beam corresponding to the target common TCI state index, or combination of indices, and implement at least two types of communication with a network device using a target common beam.

[00277] For a description of the user equipment (UE) and network device shown in the drawing, refer to the above discussion of any of the previous embodiments of the present invention. It will not be repeated here.

[00278] In embodiments of the present invention, the first indication information received by the user equipment includes a target common index, or combination of indexes, of transmission configuration indicator (TCI) states transmitted by the network device. A combination of target common TCI status indexes can be identified using a combination identifier. For example, the values 01 and 02 can indicate, respectively, different combinations of indices. Alternatively, indicating different combinations of indices can be done using different code points. For example, the three-bit code points 000 and 001 can indicate different combinations of indices, respectively. Various index combinations contain one or more TCI status indexes. One or more target common transmission configuration indicator (TCI) status indexes may be present. Each target common state index TCI corresponds to one or more reference signals (RS), with each reference signal being used to indicate a target uplink common beam and/or a target downlink common beam.

[00279] In embodiments of the present invention, the target common state TCI includes at least one of the following: a target common state TCI of the downlink, a target common state of the uplink TCI, or a target common state of the uplink and downlink TCI .

[00280] It is to be understood that the reference signal corresponding to the target common downlink TCI, eg, the RS signal, is not used to indicate the target common uplink channel beam or the uplink reference signal; and a reference signal corresponding to the target uplink common TCI status index, for example, an RS signal, is not used to indicate the target common downlink channel beam or the downlink reference signal. One or more reference signals corresponding to the target common uplink and downlink TCI, eg, one or more RS signals, may indicate the target uplink common beam or the target uplink common beam simultaneously. For example, indicating the target uplink common beam and the target downlink common beam may be performed using a single reference signal (RS) or using one or more reference signals (RS), respectively.

[00281] In one implementation, a network device may configure a mapping between target common state indices TCIs and reference signals (RS) for user equipment (UE) using radio resource control (RRC) signaling. After receiving the target TCI state index, the user equipment (UE) requests said mapping between the target common TCI state indices and reference signals (RS) according to the target TCI state index, and obtains a reference RS signal corresponding to the target TCI state index. Thus, the user equipment (UE) determines the corresponding beam according to the reference signal RS. Optionally, the mapping between the TCI status indices and the RC reference signals may be in the form of a TCI table or other form, with the TCI table mapping being provided by way of example for illustration purposes only. The TCI table may contain TCI state indices (eg, TCI state IDs), reference signal indices (reference signal IDs, RS IDs), or similar information.

[00282] It should be noted that when a combination of target common state indexes TCI is obtained, a plurality of target common state indexes TCI thereof is determined according to the correspondence relationship between the identifiers of the index combinations, or bit mapped code points, and the index combinations, wherein the corresponding target common beam determined according to a preconfigured correspondence between the TCI status indices and the RS reference signal indices.

[00283] As one possible implementation, the TCI status index transmitted by the network device may indicate either a target uplink common beam or a target downlink common beam. That is, the target uplink common state TCI is used to indicate the target uplink common beam, and the target downlink common state TCI is used to indicate the target downlink common beam.

[00284] As yet another possible implementation, a target common TCI transmitted by a network device may be used to indicate a target uplink common beam and a target downlink common beam. In one implementation, the target common TCI transmitted by the network device may be used to indicate the target uplink common beam and the target downlink common beam. In one implementation, the target common state index TCI transmitted by the network device may indicate a corresponding reference signal for each TRP, wherein said reference signal RS may indicate a target uplink common beam or a target downlink common beam. In yet another implementation, the target common TCI transmitted by the network device may indicate two corresponding reference signals for each TRP, wherein one of the two reference signals is used to indicate the target common uplink beam and the second is used to indicate the target common beam. downlink beam.

[00285] It should be noted that the target common state index TCI corresponds to one transmit and receive point (TRP) index or one CORESET pool index. That is, the target common TCI is universal for multiple transmissions with a single TRP, while different target common TCIs are used for different TRPs; and the target common state index TCI is universal for multiple transmissions with one CORESET pool index, while different target common state indexes TCI are used for different CORESET pool indexes.

[00286] It should be noted that in one embodiment of the present invention, in the case of one TRP, the common beam found will be the beam corresponding to that TRP. In yet another embodiment of the present invention, in the case of multiple TRPs, different TRPs will have corresponding target common TCIs, each target common TCI having a corresponding reference RS signal, whereby a target common beam related to corresponding TPR point.

[00287] Here, the user equipment (UE) determines the target common beam according to the target common state index TCI or a combination of indices, and performs at least two types of communication with the network device using the target common beam.

[00288] In embodiments of the present invention, a network device may pre-configure a mapping between target common state indices TCIs and reference signals (RS) for user equipment (UE) using upper layer signaling, such as radio resource control (RRC) signaling or control element signaling (CE) media access control (MAC) layer. According to the predetermined mapping, the user equipment (UE) can determine the corresponding target common beam according to the target common TCI status index dynamically indicated by the network device.

[00289] In embodiments of the present invention, the user equipment uses a target common beam that has been determined to perform at least two types of communication. Communication includes communication of a channel and/or a reference signal. Communication may be accomplished using any of the implementations described in various embodiments of the present invention, which will not be repeated herein and which do not limit the embodiments of the present invention.

[00290] In embodiments of the present invention, the first common beam target indication information is transmitted to the user equipment (UE) by the network device, whereby after receiving the first common beam target indication information transmitted by the network device, the user equipment (UE) communicates with a network device using a target common beam for at least two channels or at least two reference signals, or at least one reference signal and at least one channel. By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communication, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the amount of transmission service information.

[00291] FIG. 8 is a block diagram of another beam indicating method proposed in embodiments of the present invention, which is applied to a network device.

[00292] In embodiments of the present invention, a possible method for transmitting first common beam target indication information is provided. In accordance with the illustration of FIG. 8, the method includes the steps described below.

[00293] At step 802, media access layer control element signaling (MAC CE signaling) is transmitted to the user equipment (UE).

[00294] For a description of the user equipment (UE) and network device shown in the drawing, refer to the above discussion of any of the previous embodiments of the present invention. It will not be repeated here.

[00295] MAC CE signaling includes second indication information for activating one or more TCI status indexes, wherein one TCI status index corresponds to one TRP index or one CORESET pool index.

[00296] MAC CE signaling includes an indication bit that stores second indication information for activating one or more TCI status indexes. That is, the second indication information indicates the need to activate one or more TCI status indices.

[00297] Optionally, the MAC CE signaling has a corresponding indication bit for each TCI state index, whereby the user equipment (UE) determines the corresponding TCI state index according to the second indication information in the indication bit, wherein one TCI state index corresponds to one TRP index or one index CORESET pool.

[00298] It should be noted that said beam may be an uplink beam, an uplink beam, or a common uplink and downlink beam. The one or more activated beams may include at least one downlink beam and/or at least one downlink beam, or at least one common uplink and downlink beam. Embodiments of the present invention are not limited in the number of activated beams .

[00299] Here, the user equipment (UE) determines the first indication information according to one or more TCI status indexes activated by the second indication information.

[00300] In embodiments of the present invention, one TCI state index corresponds to one TRP index or one CORESET pool index.

[00301] In one possible scenario, one TCI status index is activated by the second indication information for one TRP index or one CORESET pool index, whereby the first indication information is determined to be said one TCI status index activated by the second indication information . For example, one TCI may have one TCI status activated for one TRP, then the TCI status index corresponding to that TRP will be the activated TCI status index. In one example, the activated TCI may correspond to a target downlink common TCI, in which case the reference signal corresponding to the activated TCI indicates the target downlink common beam, and the target downlink common beam for a given TRP will be a downlink beam indicated by a reference signal corresponding to said TCI status index. In yet another example, the activated TCI may correspond to a target uplink common TCI, in which case the reference signal corresponding to the activated TCI indicates the target uplink common beam, and the target uplink common beam for a given TRP there will be an uplink beam that is indicated by a reference signal corresponding to said TCI status index. In yet another example, the activated TCI status index may correspond to the target common TCI status index, in which case the reference signal corresponding to the activated TCI status index indicates the target uplink common beam and the target downlink common beam, and the target uplink common beam communication and the target common downlink beam for a given TRP will be the uplink beam and the downlink beam, which are indicated by a reference signal corresponding to said TCI status index.

[00302] In one possible scenario, the second indication information activates a plurality of TCI status indexes for one TRP index or one CORESET pool index, that is, it is necessary to determine, as the first indication information, a target common index, or combination of indexes, of the TCI status according to the corresponding TRP index or CORESET pool index from this set of TCI status indexes. In one implementation, a first signaling with downlink control information (DCI) is received from a network device. The first DCI signaling contains first indication information, wherein the first indication information includes one target common TCI state index, or combination of indices, from a plurality of TCI state indices activated by the second indication information.

[00303] It should be noted that the index combination contains a plurality of common TCI status indexes, with different TCI status indexes corresponding to different TRPs or different CORESET pool indices.

[00304] In embodiments of the present invention, the user equipment uses a target common beam that has been determined to perform at least two types of communication. However, the communication can be carried out using any of the implementations described in various embodiments of the present invention, which will not be repeated here and which do not limit the embodiments of the present invention. Communication includes communication of a channel and/or a reference signal.

[00305] In embodiments of the present invention, the first common beam target indication information is transmitted to the user equipment (UE) by the network device, whereby after receiving the first common beam target indication information transmitted by the network device, the user equipment (UE) communicates with a network device using a target common beam for at least two channels or at least two reference signals, or at least one reference signal and at least one channel. By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communication, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the volume transmitted service information.

[00306] FIG. 9 is a block diagram of yet another beam indicating method proposed in embodiments of the present invention. The proposed method is performed on a network device.

[00307] In embodiments of the present invention, a possible method for transmitting first common beam target indication information is provided. In accordance with the illustration of FIG. 9, the method includes the steps described below.

[00308] At step 901, the first signaling with downlink control information (DCI) is transmitted to the user equipment (UE).

[00309] For a description of the user equipment (UE) and network device shown in the drawing, refer to the above discussion of any of the previous embodiments of the present invention. It will not be repeated here.

[00310] The first DCI signaling includes first target common beam indication information. That is, the target common index, or combination of indices, TCI states, and resource configuration information are in different DCI signaling, wherein in the first DCI signaling is the target common index, or combination of indices, TCI states, that is, the first information instructions.

[00311] The first DCI signaling may be based on a single TRP or multiple TRPs, without limiting this embodiment of the invention in this regard.

[00312] In one possible implementation of embodiments of the present invention, a user equipment (UE) uses one or more receive beams to receive one or more DCI signaling transmissions, that is, a network device uses one or more TRPs to perform one or more DCI transmissions - signaling, with each TRP corresponding to a separate beam, which avoids blocking signal transmission and improves communication quality to ensure the reception of the first DCI signaling.

[00313] At step 902, first hybrid automatic retransmission request feedback information, HARQ, is received from the user equipment (UE).

[00314] The first HARQ feedback information is used to indicate to the network device whether the first DCI signaling was successfully received.

[00315] The HARQ feedback resource used by the user equipment (UE) to transmit the first HARQ feedback information is configured using the first DCI signaling or is set by default.

[00316] In one possible scenario, the first DCI signaling is transmitted, by the network device, once, and accordingly, from the user equipment (UE) point of view, one or more candidate PUCCH/PUSCH resources may be present for transmitting the first feedback information HARQ.

[00317] In yet another possible scenario, the first DCI signaling is transmitted, by the network device, multiple times, and accordingly, from the user equipment (UE) point of view, there may be one or more candidate PUCCH/PUSCH resources for transmitting the first HARQ feedback information.

[00318] Optionally, the user equipment (UE) may transmit first HARQ feedback information whenever it receives the first DCI signaling.

[00319] Alternatively, the network device may periodically transmit the first DCI signaling at N transmission instants, respectively, and thus the user equipment (UE) may be configured to use L candidate PUCCH/PUSCH resources to transmit the first HARQ feedback information. where L is less than or equal to N, a portion of the L candidate PUCCH/PUSCH resources precede the end of the N transmission instants, and a portion of them are located after the end of the N transmission instants. In case of correct reception, by the user equipment (UE), of the first DCI signaling before the N transmission times, the user equipment (UE) may select one of the PUCCH/PUSCH candidate resources to transmit HARQ feedback information up to the N transmission times. In the case of the user equipment (UE) correctly receiving the first DCI signaling after the end of the N transmission times, the UE may select another candidate PUCCH/PUSCH resource for transmitting the HARQ feedback information after the end of the N transmission times.

[00320] Alternatively, the network device may periodically transmit the first DCI signaling at N transmission instants, respectively, and thus, the user equipment (UE) may be configured to use one PUCCH/PUSCH candidate resource to transmit the first HARQ feedback information, at herein, the user equipment (UE) may transmit the first HARQ feedback information after the completion of the N transmission instants.

[00321] Here, during subsequent communication of the user equipment (UE) with the network device, the user equipment (UE) uses a target common beam to perform at least two types of communication with the network device. Communication includes communication of a channel and/or a reference signal.

[00322] In one embodiment of the present invention, the transmit beam for transmitting the second HARQ feedback information is a transmit beam corresponding to the target common beam corresponding to the target common TCI status index or combination of indices in the first DCI signaling.

[00338] In embodiments of the present invention, a possible method for transmitting first common beam target indication information is provided. In accordance with the illustration of FIG. 10, the method includes the steps described below.

[00339] In step 1001, the first signaling with downlink control information (DCI) is transmitted to the user equipment (UE).

[00340] For a description of the user equipment (UE) and network device shown in the drawing, refer to the above discussion of any of the previous embodiments of the present invention. It will not be repeated here.

[00341] In embodiments of the present invention, the first DCI signaling includes first indication information and contains resource configuration information for configuring a communication resource for at least one of a reference signal, a PRACH, a PUSCH, a PUCCH, or a PDSCH.

[00342] In one possible implementation, the first DCI signaling contains resource configuration information for a downlink communication resource, wherein the first DCI signaling is DCI signaling that is used for scheduling downlink resources. The first DCI signaling may take the form of predefined DCI signaling, for example, DCI information format 10, 11 or 12, newly defined DCI signaling, or other DCI signaling that will not be listed individually in embodiments of the present invention, when The present invention is not limited in this regard.

[00343] In yet another possible implementation, the first DCI signaling contains resource configuration information for an uplink communication resource, wherein the first DCI signaling is DCI signaling that is used for scheduling uplink resources. The first DCI signaling may take the form of predefined DCI signaling, for example, format 0_0, 0_1 or 0_2 DCI information, newly defined DCI signaling, or other DCI signaling that will not be listed separately in embodiments of the present invention, when The present invention is not limited in this regard.

[00344] In a third possible implementation, the first DCI signaling contains resource configuration information for uplink and downlink communication resources, wherein the first DCI signaling is DCI signaling that is used for scheduling uplink and downlink resources.

[00345] The first DCI signaling may be DCI signaling for resource configuration for a single TRP or for multiple TRPs, without limiting this embodiment of the invention in this regard.

[00346] At step 1002, second HARQ feedback information is received from the user equipment (UE).

[00347] In embodiments of the present invention, in the case where the HARQ feedback resource is configured, the second HARQ feedback information is transmitted to the network device.

[00348] The user equipment (UE) may use the same beam that was used to transmit the first DCI signaling to transmit the second HARQ feedback information to the network device, or use the target common beam indicated by the first indication information contained in the first DCI signaling, for transmitting the second HARQ feedback information to the network device, without limiting the present invention in this regard.

[00349] In one possible implementation, if a network device schedules two HARQ feedback resources using the first DCI signaling, or if the user equipment (UE) is pre-configured to use two HARQ feedback resources, the second HARQ feedback information includes: the first feedback information configured to return information about whether the first DCI signaling has been successfully received, and second feedback information configured to return information about whether the PDSCH and/or downlink reference signal configured to using the first DCI signaling.

[00350] In yet another possible implementation, if a network device schedules one HARQ feedback resource using first DCI signaling, or if the user equipment (UE) is pre-configured to use one HARQ feedback resource, the second HARQ feedback information includes: first feedback information and second feedback information for which said HARQ feedback resource is shared.

[00351] In one implementation of embodiments of the present invention, the HARQ feedback resources used to transmit the first feedback information and/or the second feedback information are configured with the first DCI signaling or are set by default.

[00352] In one implementation of embodiments of the present invention, the HARQ feedback resources used to transmit the first feedback information and/or the second feedback information are identical HARQ feedback resources and/or different HARQ feedback resources.

[00353] In one example, when the HARQ feedback resources used to transmit the first feedback information and/or the second feedback information are identical HARQ feedback resources and/or different HARQ feedback resources, the first feedback information and/or or the second feedback information corresponds to the same or different bits in one HARQ feedback resource.

[00354] In one possible scenario, the first DCI signaling is transmitted, by the network device, once, and accordingly, from the user equipment (UE) point of view, one or more candidate PUCCH/PUSCH resources may be present for transmitting the second feedback information HARQ.

[00355] In yet another possible scenario, the first DCI signaling is transmitted, by the network device, multiple times, and accordingly, from the user equipment (UE) point of view, one or more candidate PUCCH/PUSCH resources may be present for transmitting the second information HARQ feedback. Optionally, the user equipment (UE) may transmit second HARQ feedback information whenever it receives the first DCI signaling. Alternatively, the network device may periodically transmit the first DCI signaling at N transmission instants respectively, and thus the user equipment (UE) may be configured to use L candidate PUCCH/PUSCH resources to transmit the first HARQ feedback information, where L is less than or is N, a portion of the L candidate PUCCH/PUSCH resources precede the end of the N transmission instants, and a portion of them are located after the end of the N transmission instants. In case of correct reception, by the user equipment (UE), of the first DCI signaling before the N transmission times, the user equipment (UE) may select one of the PUCCH/PUSCH candidate resources for transmitting the second HARQ feedback information up to the N transmission times. In the case of the user equipment (UE) correctly receiving the first DCI signaling after the end of the N transmission times, the user equipment (UE) may select a candidate PUCCH/PUSCH resource for transmitting the second HARQ feedback information after the end of the N transmission times. Alternatively, the network device may periodically transmit the first DCI signaling at N transmission instants, respectively, and thus, the user equipment (UE) may be configured to use one PUCCH/PUSCH candidate resource to transmit the first HARQ feedback information, wherein the user equipment The UE may transmit second HARQ feedback information after the N transmission instants.

[00356] In one embodiment of the present invention, the transmit beam for transmitting the second HARQ feedback information is a transmit beam corresponding to the target common beam corresponding to the target common TCI status index or combination of indices in the first DCI signaling.

[00357] In one embodiment of the present invention, the transmit beam for transmitting the second HARQ feedback information is a transmit beam corresponding to the receive beam for receiving the first DCI signaling.

[00358] At step 1003, communication is carried out with the user equipment (UE) according to the resource configuration information contained in the first DCI signaling.

[00359] In embodiments of the present invention, in a case where HARQ feedback information indicating whether the first DCI signaling has been successfully received is not transmitted separately, the network device determines whether the user equipment (UE) has received the first DCI signaling, that is, whether the network device has completed configuration, according to whether the user equipment (UE) uses the configured communication resource to communicate with the network device.

[00360] In one implementation of embodiments of the present invention, in the case where the time interval between transmission from the user equipment (UE) and reception of the first DCI signaling is less than a threshold value, the same beam as for DCI signaling is used for communication.

[00361] In yet another implementation of embodiments of the present invention, in the case where the time interval between transmission from the user equipment (UE) and reception of the first DCI signaling is greater than or equal to a threshold value, a target common beam corresponding to the target common index is used for communication TCI states in the first DCI signaling.

[00362] In embodiments of the present invention, the threshold value in step 1003 is set in the user equipment by default. In one possible implementation, the threshold may be determined by the network device. In yet another possible implementation, the determination of the threshold value may be performed by the network device according to the previous communication time, without limiting the embodiments of the present invention in this regard.

[00363] In one possible implementation, the network device transmits threshold indication information to the user equipment (UE) in accordance with the reference time transmitted by the user equipment (UE). The reference time includes a time for decoding the first DCI signaling, a time for HARQ feedback corresponding to the first DCI signaling, and a time for beam switching; or the reference time includes a HARQ feedback time corresponding to the first DCI signaling and a time for beam switching. Accordingly, the user equipment (UE) determines that the first DCI signaling is decoding. HARQ feedback and beam switching may be performed within the reference time, or that HARQ feedback and beam switching may be performed within the reference time.

[00364] In one possible implementation, the threshold value determined by the network device is greater than or equal to the reference time.

[00365] Embodiments of the present invention are discussed in detail based on examples in which communication includes uplink transmission from a user equipment to a network device and/or downlink reception by the user equipment.

[00366] In embodiments of the present invention, in the case where the HARQ feedback resource indicating whether the first DCI signaling has been successfully received is not separately configured, the network device determines whether the user equipment (UE) has received the first DCI signaling, that is, whether the network device has completed configuration, according to whether the user equipment (UE) uses the configured communication resource for downlink transmissions to the network device; or the network device uses the configured communication resource for downlink transmission to the user equipment (UE) and determines whether the user equipment (UE) has successfully received and decoded the first DCI signaling according to the HARQ feedback information that is returned by the user equipment (UE), and indicates whether the user equipment (UE) successfully received and decoded the downlink transmission.

[00367] It should be noted that in the case where the time interval between the uplink communication and/or downlink communication and the first DCI signaling is less than a threshold value, for the uplink communication and/or downlink communication communications use the same beam as for the first DCI signaling. In the case where the time interval between the uplink transmission and/or downlink transmission and the first DCI signaling is greater than or equal to the threshold value, the same beam is used for the uplink transmission and/or downlink transmission. same as the target common beam corresponding to the target common TCI status index or combination of indices in the first DCI signaling. The threshold value is at least one of the time required for the user equipment (UE) to return, to the network device, information about whether the first DCI signaling was correctly received, or the time for beam switching. The time threshold may be determined by an agreement between the user equipment (UE) and the network device.

[00368] After the network device determines that the user equipment (UE) has correctly received the first DCI signaling, in subsequent communications between the user equipment (UE) and the network device, the user equipment (UE) may use the target common beam to implement at least at least two types of communication with a network device.

[00369] Also, time is counted from the moment when the first DCI signaling is received, and at least two types of communication are performed if it is determined that the counted time has reached the above-mentioned threshold, that is, channel and/or reference signal communication at The at least two types of communication mentioned above are performed using the network device using a target common beam, which reduces the amount of signaling overhead.

By only transmitting the first target common beam indication information once, the target common beam can be used for multiple types of communication, including reference signal transmission and channel transmission, that is, separate beam indications are not needed for each channel transmission or reference signal transmission, thereby reducing the amount of transmission service information.

[00372] Embodiments of the present invention provide a possible beam pointing and beam switching method. In embodiments of the present invention, as one possible implementation, third indication information may also be transmitted to the user equipment, wherein the third indication information is configured to direct the user equipment (UE) to use a target common beam or a dedicated beam to implement the at least mentioned at least two types of communication.

[00373] In one implementation, the third indication information received by the user equipment may be received before the user equipment receives the first indication information, causing the user equipment to decide whether to use the target common beam or whether to use a dedicated beam to accomplish the above. at least two types of communication according to the third indication information. In one example, if a decision is made to use a dedicated beam to carry out at least two types of communication, the two types of communication are carried out in accordance with the dedicated beam. Different signaling is used to indicate a dedicated beam for each transmission. In yet another example, if it is decided to use a target common beam to perform at least two types of communication, the target common beam used for communication is further determined according to the received first indication information. For detailed information regarding this, reference may be made to any of the above-described implementations of any of the embodiments of the present invention, which will not be repeated here.

[00374] In yet another implementation, the third indication information received by the user equipment may be received after the user equipment receives the first indication information, wherein the network device determines that the target common beam should be switched to a dedicated beam according to the third indication information , also, the dedicated beam must be separately indicated by means of separate signaling for each channel and/or each reference signal. In one possible application scenario, a network device may need to switch a given channel or reference signal to a dedicated beam, that is, only the indication information for that dedicated dedicated beam corresponding to said channel or reference signal may be transmitted, while the remaining channels and reference signals , which have not received the dedicated beam indication information, continue to use the target common beam. In yet another possible application scenario, the network device may switch each channel and/or reference signal currently using a target common beam to a dedicated beam and transmit dedicated beam indication information for each channel or reference signal, respectively.
