[0202] A network controlled repeater (NCR) is introduced in the related art to support beamforming of a forwarding link to improve the receiving performance of a terminal / user equipment (UE).

[0203] The so-called intelligent behavior of the repeater means that the repeater can adjust the sending or receiving process in real time according to the actual needs of the service terminal. Generally, in order to support the real-time adjustment process of the smart repeater (SR), the base station needs to send some auxiliary information or control information to the SR, so the SR is also called NCR.

[0204] Figure 1 This is a schematic diagram of NCR's network topology. Figure 1 As shown, NCR includes two functional modes: NCR terminal (function) and NCR forwarding (function):

[0205] NCR terminal: It is used to interact with the base station for control signaling; the control signaling user controls the forwarding parameters of the NCR, for example, controls the beam direction of the access link.

[0206] NCR forwarding: used to forward signals from the base station to the terminal, and forward signals from the terminal to the base station. And related forwarding parameters are sent by the terminal of the NCR. The link from the NCR to the UE is called a forwarding link or an access link.

[0207] Figure 2 It is a schematic diagram of the beam indication information of the control signaling indicating the access link, such as Figure 2 As shown, for the TDD (time division duplex, or unpaired spectrum) scenario, the base station (gNB) instructs the NCR on the beam information on the forwarding link through control signaling, and the indicated beam information includes the beam index and the time domain indication corresponding to the beam.

[0208] The control signaling includes: periodic beam information configured by RRC signaling; semi-persistent beam information activated by MAC-CE; and dynamic beam indication information indicated by the physical layer.

[0209] Taking the dynamic beam indication information indicated by the physical layer as an example, the specific steps of beam indication are as follows:

[0210] Step 1: Configure the non-periodic forwarding link configuration information through high-level signaling.

[0211] Aperiodic forwarding link configuration information (AperiodicFwdConfig) includes the following:

[0212] 1. K aperiodic forwarding time domain resource information (AperiodicFwdTimeResource), K is greater than or equal to 1, and each aperiodic forwarding resource includes an aperiodic forwarding resource ID and a corresponding time domain resource.

[0213] 2. Reference subcarrier spacing SCS.

[0214] 3. Aperiodic beam field indication bit width M (aperiodicBeamFieldWidth), used to indicate the number of bits occupied in dynamic signaling.

[0215] 4. Indication of the number of beams N (numberOfFields): used to indicate the time domain and the number of corresponding beams indicated by a dynamic signaling.

[0216] Step 2: The base station sends physical layer signaling to indicate the dynamic beam information of the forwarding link.

[0217] The relevant physical layer signaling includes the following:

[0218] 1. Multiple beam index indications (beamindex), for example, Beamindex 1, Beam index 2,…, Beamindex N.

[0219] 2. Multiple time resource indications (Time resource indication), for example, Time resource indication 1, Time resource indication 2,…, Time resource indication N.

[0220] Where N corresponds to the number of beams N indicated by the configuration information in step 1. The number of bits occupied by each beam index indication is the bit width M of the non-periodic beam domain indication indicated in step 1. The number of bits occupied by each Time resource indication indication is K is K non-periodic forwarding time domain resource information configured in step 1, and the indication information is the non-periodic forwarding resource identifier (ID).

[0221] For TDD scenarios, uplink and downlink are on the same spectrum, and beam indication does not distinguish between uplink and downlink. If the time domain information corresponds to uplink, the beam indication is uplink, otherwise it is downlink. That is:

[0222] The terminal indicates the uplink / downlink time domain ratio according to the uplink / downlink time domain ratio indication information. When the time corresponding to the time domain resource indication is uplink, the beam indication is used for uplink transmission.

[0223] The terminal indicates the uplink / downlink time domain ratio according to the information. When the time corresponding to the time domain resource indication is downlink, the beam indication is used for downlink transmission.

[0224] Figure 3 This is a schematic diagram of the application of beam indication in TDD scenarios, such as Figure 3As shown, it is assumed that the base station indicates 8 beams in the time domain, corresponding to time slots 1-8 respectively. For time slot-1, it is downlink, so beam-1 is used for downlink transmission. For time slot-4, it is uplink, so beam-4 is used for uplink transmission.

[0225] For the FDD (frequency division duplex, or paired spectrum) scenario, the uplink and downlink are on different spectrums, and the beam indication scheme in the TDD scenario in the related technology cannot be used. How to indicate the beam information corresponding to the uplink and downlink spectrum is a problem that needs to be studied.

[0226] It should be noted that: NCR uses the corresponding indicated beam to forward the link in the corresponding indicated time domain according to the beam indication indicated by the base station, and does not forward (i.e. stops sending or receiving on the forwarding link) in the time domain without indication. This usage method is also applicable to FDD scenarios.

[0227] Based on the above technical problems, the method, device and storage medium for indicating the forwarding link beam provided in the present application indicate through beam indication information that each beam resource configured for NCR for use on the forwarding link is used for uplink or downlink transmission, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0228] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0229] Figure 4 is one of the flowcharts of the method for indicating a forwarding link beam provided in an embodiment of the present application, such as Figure 4 As shown, an embodiment of the present application provides a method for indicating a forwarding link beam, and the execution subject may be an intelligent repeater, such as an NCR. The method includes:

[0230] Step 401: Obtain beam indication information sent by a network device.

[0231] Specifically, in an embodiment of the present application, the terminal first obtains beam indication information sent by a network device; the beam indication information is used to indicate that each beam resource configured for the NCR for use on a forwarding link is used for uplink or downlink transmission.

[0232] Uplink transmission is the transmission direction from the terminal to the NCR, which can also be called the reception of the NCR on the access link.

[0233] Downlink transmission is the transmission direction from NCR to terminal, which can also be called the transmission of NCR on the access link.

[0234] The beam indication information may include a variety of different information.

[0235] For example, the beam indication information may include two beam resource set lists, where each beam resource in each beam resource set in the first beam resource set list is used for uplink transmission; and each beam resource in each beam resource set in the second beam resource set list is used for downlink transmission.

[0236] For another example, the beam indication information includes multiple beam resource sets, each beam resource in the Nth beam resource set among the multiple beam resource sets is used for uplink transmission, and each beam resource in the N+1th beam resource set is used for downlink transmission, where N is a positive integer.

[0237] For another example, the beam indication information includes a dynamic scheduling command for beam resources. The beam resources corresponding to a value of 0 in a certain indication field information in the dynamic scheduling command are used for uplink transmission, and the beam resources corresponding to a value of 1 in a certain indication field information in the dynamic scheduling command are used for downlink transmission.

[0238] Step 402: Based on the beam indication information, determine that one or more beam resources configured by the network device are used for uplink or downlink transmission; wherein the one or more beam resources are used on a forwarding link.

[0239] Specifically, in an embodiment of the present application, after the NCR obtains the beam indication information sent by the network device, it determines one or more beam resources configured by the network device for uplink or downlink transmission based on the beam indication information; wherein the one or more beam resources are used on the forwarding link.

[0240] For example, the beam indication information may include two beam resource set lists. After the NCR obtains the two beam resource set lists, it determines that each beam resource in each beam resource set in the first beam resource set list is used for uplink transmission, and each beam resource in each beam resource set in the second beam resource set list is used for downlink transmission.

[0241] For another example, the beam indication information includes multiple beam resource sets. After the NCR obtains the multiple beam resource sets sent by the network device, it determines that each beam resource in the Nth beam resource set among the multiple beam resource sets is used for uplink transmission, and each beam resource in the N+1th beam resource set is used for downlink transmission, where N is a positive integer.

[0242] For another example, the beam indication information includes a dynamic scheduling command for beam resources. After the NCR obtains the dynamic scheduling command for beam resources sent by the network device, it determines that the beam resources corresponding to a value of 0 in a certain indication field information in the dynamic scheduling command are used for uplink transmission, and the beam resources corresponding to a value of 1 in a certain indication field information in the dynamic scheduling command are used for downlink transmission.

[0243] The method for indicating the forwarding link beam provided in the present application indicates through beam indication information that each beam resource used on the forwarding link configured for the NCR is used for uplink or downlink transmission, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0244] In some embodiments, the beam indication information includes two beam resource set lists, each of the beam resource set lists includes one or more beam resource sets, and each of the beam resource sets includes one or more beam resources;

[0245] The determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0246] Determine that each beam resource in each beam resource set in the first beam resource set list configured by the network device is used for uplink transmission;

[0247] Determine that each beam resource in each beam resource set in the second beam resource set list configured by the network device is used for downlink transmission.

[0248] Specifically, in an embodiment of the present application, the beam indication information includes two beam resource set lists, each of the beam resource set lists includes one or more beam resource sets, and each of the beam resource sets includes one or more beam resources.

[0249] For example, the beam resource set list may be a periodic forwarding time domain resource set list (periodicFwdRsrcSetToAddModList).

[0250] It can be pre-agreed through a protocol that each beam resource in each beam resource set in the first beam resource set list is used for uplink transmission, and each beam resource in each beam resource set in the second beam resource set list is used for downlink transmission.

[0251] For example, each beam resource in each beam resource set in List-1 is used for uplink transmission, and each beam resource in each beam resource set in List-2 is used for downlink transmission; or vice versa.

[0252] After acquiring two beam resource set lists sent by the network device, the NCR determines that each beam resource in each beam resource set in the first beam resource set list configured by the network device is used for uplink transmission.

[0253] Determine that each beam resource in each beam resource set in the second beam resource set list configured by the network device is used for downlink transmission.

[0254] For periodic beam indication, the network device can configure two beam resource set lists to the NCR through a Radio Resource Control (RRC) message.

[0255] For example, the base station configures two periodic forwarding time domain resource set lists (periodicFwdRsrcSetToAddModList) in the forwarding configuration (NCR_FwdConfig), one of which is used for uplink beam indication, and the other is used for downlink beam indication.

[0256] The forwarding configuration NCR-FwdConfig includes the following:

[0257] {

[0258] Periodic forwarding time domain resource set list-1 (PeriodicFwdRsrcSetToAddModList-1) (when the duplex mode is FDD, the configuration information of this list is used to indicate the uplink forwarding link beam indication);

[0259] Periodic forwarding time domain resource set list-2 (PeriodicFwdRsrcSetToAddModList-1) (when the duplex mode is FDD, the configuration information of this list is used to indicate the downlink forwarding link beam indication).

[0260] }

[0261] Of course, the protocol may also stipulate that: the periodic forwarding time domain resource set list-1 configuration information is used to indicate the downlink beam indication, and the periodic forwarding time domain resource set list-2 configuration information is used to indicate the uplink beam indication, and there is no restriction here.

[0262] For another example, the base station can configure the "forwarding configuration (NCR_FwdConfig)" twice, and indicate in the configuration information whether this configuration is for an uplink or downlink beam indication.

[0263] The forwarding configuration NCR-FwdConfig includes the following:

[0264] {

[0265] Periodic forwarding time domain resource set list (PeriodicFwdRsrcSetToAddModList)

[0266] Uplink / Downlink indicator

[0267] Aperiodic forwarding configuration (aperiodicFwdConfig)

[0268] }

[0269] Among them, "uplink / downlink indication" indicates whether this configuration is used for uplink or downlink beam indication. For example, the enumeration type {DOWNLINK, UPLINK, BOTH}, DOWNLINK indicates that it is used for downlink, UPLINK indicates that it is used for downlink, and BOTH indicates that it is used for both uplink and downlink.

[0270] It can also be specified by the protocol in the "Forwarding Configuration (NCR_FwdConfig)" configuration:

[0271] If the "Forwarding Configuration (NCR_FwdConfig)" is configured once, the configuration is used for both upstream and downstream;

[0272] If "Forwarding Configuration (NCR_FwdConfig)" is configured twice, the first one is used for uplink and the second one is used for downlink, or vice versa.

[0273] Among them, a periodic forwarding time domain resource set list (PeriodicFwdRsrcSetToAddModList) includes multiple periodic forwarding time domain resource sets (PeriodicFwdResourceSet), and a periodic forwarding time domain resource set includes multiple periodic forwarding resources (PeriodicFwdResource).

[0274] For semi-static beam indication, the beam resources are indicated for uplink or downlink transmission through RRC configuration and MAC-CE activation command.

[0275] For example, different logical channel number identifiers (LCID values) are used to indicate that the beam resource is used for uplink or downlink transmission. For FDD scenarios, the logical channel number identifier code point 223 indicates that the beam resource is used for uplink transmission, and the logical channel number identifier code point 224 indicates that the beam resource is used for downlink transmission.

[0276] For another example, Figure 5 is a schematic diagram of MAC-CE provided in an embodiment of the present application, such as Figure 5As shown, the (reserved) bit R1 in the MAC-CE activation command is used to indicate that the beam resources activated this time are used for uplink or downlink transmission. For FDD scenarios, when the R1 value is 0, it indicates that the beam resources activated / deactivated by the MAC-CE this time are used for uplink transmission, and when the R1 value is 1, it indicates that the beam resources activated / deactivated by the MAC-CE this time are used for downlink transmission, or, when the R1 value is 0, it indicates that the beam resources activated / deactivated by the MAC-CE this time are used for downlink transmission, and when the R1 value is 1, it indicates that the beam resources activated / deactivated by the MAC-CE this time are used for uplink transmission. MAC-CE can activate / deactivate a list of beam resource sets, activate / deactivate a beam resource set, or activate / deactivate a beam resource.

[0277] The method for indicating the forwarding link beam provided in the present application configures two beam resource set lists to indicate that each beam resource in each beam resource set in the first beam resource set list is used for uplink transmission, and each beam resource in each beam resource set in the second beam resource set list is used for downlink transmission, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0278] In some embodiments, the obtaining of beam indication information sent by the network device includes:

[0279] Determine two beam resource set lists configured by the network device;

[0280] Obtain indication field information from each of the beam resource set lists, where the indication field information is used to indicate that each beam resource in each beam resource set in the corresponding beam resource set list is used for uplink or downlink transmission.

[0281] In some embodiments, determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0282] Based on the indication field information, it is determined that each beam resource in each beam resource set in the corresponding beam resource set list is used for uplink or downlink transmission.

[0283] Specifically, in an embodiment of the present application, by adding indication field information, it is indicated that each beam resource in each beam resource set in the beam resource set list is used for uplink or downlink transmission.

[0284] For example, if the value of the indication domain information in the first beam resource set list is 0, then each beam resource in each beam resource set in the first beam resource set list is used for uplink transmission; if the value of the indication domain information in the second beam resource set list is 1, then each beam resource in each beam resource set in the second beam resource set list is used for downlink transmission.

[0285] The method for indicating the forwarding link beam provided in the present application configures the indication field information in the beam resource set list to indicate that each beam resource in each beam resource set in the beam resource set list is used for uplink or downlink transmission, thereby realizing the beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0286] In some embodiments, the beam indication information includes a plurality of beam resource sets, each of the beam resource sets includes one or more beam resources;

[0287] The determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0288] Determine that each beam resource in the Nth beam resource set among the multiple beam resource sets configured by the network device is used for uplink transmission, and each beam resource in the N+1th beam resource set is used for downlink transmission; or,

[0289] Determine that each beam resource in the Nth beam resource set among the multiple beam resource sets configured by the network device is used for downlink transmission, and each beam resource in the N+1th beam resource set is used for uplink transmission;

[0290] Wherein, N is a positive integer.

[0291] Specifically, in an embodiment of the present application, the beam indication information includes multiple beam resource sets, and each of the beam resource sets includes one or more beam resources.

[0292] It can be agreed in advance through the protocol that each beam resource in the first beam resource set is used for uplink transmission, each beam resource in the second beam resource set is used for downlink transmission, each beam resource in the third beam resource set is used for uplink transmission, each beam resource in the fourth beam resource set is used for downlink transmission, and so on.

[0293] After obtaining a list of multiple beam resource sets sent by the network device, the NCR determines that each beam resource in the Nth beam resource set among the multiple beam resource sets configured by the network device is used for uplink transmission, and each beam resource in the N+1th beam resource set is used for downlink transmission; or vice versa; where N is a positive integer.

[0294] The method for indicating the forwarding link beam provided in the present application configures the indication field information in the beam resource set list to indicate that each beam resource in each beam resource set in the beam resource set list is used for uplink or downlink transmission, thereby realizing the beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0295] The method for indicating the forwarding link beam provided in the present application configures multiple beam resource set lists to indicate that each beam resource in each beam resource set in the Nth beam resource set list is used for uplink transmission, and each beam resource in each beam resource set in the N+1th beam resource set list is used for downlink transmission, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0296] In some embodiments, the beam indication information includes a plurality of beam resource sets, each of the beam resource sets includes one or more beam resources;

[0297] The determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0298] Determine that each beam resource in the 1st to Nth beam resource sets among the multiple beam resource sets configured by the network device is used for uplink transmission, and each beam resource in the N+1th to last beam resource set is used for downlink transmission; or,

[0299] Determine that each beam resource in the 1st to Nth beam resource sets among the multiple beam resource sets configured by the network device is used for downlink transmission, and each beam resource in the N+1th to last beam resource set is used for uplink transmission;

[0300] Wherein, N is a positive integer.

[0301] Specifically, in an embodiment of the present application, in an embodiment of the present application, the beam indication information includes multiple beam resource sets, and each of the beam resource sets includes one or more beam resources.

[0302] It can be agreed in advance through a protocol that each beam resource in the 1st to Nth beam resource sets is used for uplink transmission, and each beam resource in the N+1th to last beam resource set is used for downlink transmission; or vice versa.

[0303] For example, each beam resource in the 1st to M / 2nd beam resource sets is used for uplink transmission, and each beam resource in the M / 2nd to Mth beam resource sets is used for downlink transmission, where M is the total number of beam resource sets and M is an even number.

[0304] After acquiring a list of multiple beam resource sets sent by the network device, the NCR determines that each beam resource in the 1st to Nth beam resource sets is used for uplink transmission, and each beam resource in the N+1th to last beam resource sets is used for downlink transmission; or,

[0305] It is determined that each beam resource in the 1st to Nth beam resource sets is used for downlink transmission, and each beam resource in the N+1th to last beam resource set is used for uplink transmission.

[0306] The method for indicating the forwarding link beam provided in the present application configures multiple beam resource set lists to indicate that each beam resource in the 1st to Nth beam resource sets is used for uplink transmission, and each beam resource in the N+1th to the last beam resource set is used for downlink transmission; or vice versa, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0307] In some embodiments, the beam indication information includes multiple beam resource set identifiers, each of the beam resource set identifiers is used to indicate a beam resource set, and the beam resource set includes one or more beam resources;

[0308] The determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0309] Determine that each beam resource in a beam resource set with an even-numbered beam resource set identifier value is used for uplink transmission, and each beam resource in a beam resource set with an odd-numbered beam resource set identifier value is used for downlink transmission; or,

[0310] It is determined that each beam resource in a beam resource set whose beam resource set identifier value is an even number is used for downlink transmission, and each beam resource in a beam resource set whose beam resource set identifier value is an odd number is used for uplink transmission.

[0311] Specifically, in an embodiment of the present application, the beam indication information includes multiple beam resource set identifiers, each of the beam resource set identifiers is used to indicate a beam resource set, and the beam resource set includes one or more beam resources.

[0312] It can be agreed in advance through the protocol that each beam resource in a beam resource set with an even-numbered beam resource set identifier value is used for uplink transmission, and each beam resource in a beam resource set with an odd-numbered beam resource set identifier value is used for downlink transmission; or vice versa.

[0313] After obtaining multiple beam resource set lists sent by the network device, the NCR determines that each beam resource in the beam resource set with an even-numbered beam resource set identification value is used for uplink transmission, and each beam resource in the beam resource set with an odd-numbered beam resource set identification value is used for downlink transmission; or vice versa.

[0314] The above identification value is an odd number, which can also be expressed as identification value %2=1, and the identification value is an even number, which can also be expressed as identification value %2=0, where % represents the remainder.

[0315] The method for indicating the forwarding link beam provided in the present application configures multiple beam resource set identifiers to indicate that each beam resource in a beam resource set with an even-numbered beam resource set identifier value is used for uplink transmission, and each beam resource in a beam resource set with an odd-numbered beam resource set identifier value is used for downlink transmission; or vice versa, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0316] In some embodiments, the obtaining of beam indication information sent by the network device includes:

[0317] Determine a plurality of beam resource sets configured by the network device;

[0319] In some embodiments, determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0320] Based on the indication field information, it is determined that each beam resource in the corresponding beam resource set is used for uplink or downlink transmission.

[0321] Specifically, in an embodiment of the present application, by adding indication field information in a beam resource set, it is indicated that each beam resource in the beam resource set is used for uplink or downlink transmission.

[0322] For example, if the value of the indication domain information in the first beam resource set is 0, then each beam resource in the first beam resource set is used for uplink transmission; if the value of the indication domain information in the second beam resource set is 1, then each beam resource in the second beam resource set is used for downlink transmission.

[0323] The method for indicating the forwarding link beam provided in the present application configures indication domain information in the beam resource set to indicate that each beam resource in the beam resource set is used for uplink or downlink transmission, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0326] It is determined that the beam resources whose number of periodic time domain parameters used on the forwarding link configured for the NCR is a first value are applied to uplink transmission, and the beam resources whose number of periodic time domain parameters is a second value are applied to downlink transmission.

[0327] Specifically, in the embodiment of the present application, each periodic forwarding resource includes the following information:

[0328] Periodic forwarding resource (PeriodicFwdResource) =

[0329] {

[0330] Periodic forwarding resource ID (periodicFwdRsrcId) (periodic resource identification number);

[0331] Periodic time domain parameters (periodicTimeRsrc) (configured time domain parameters);

[0332] Beam indication (beamIndex) (the beam index corresponding to the above periodic time domain parameters).

[0333] }

[0334] The periodic time domain parameters include the following information:

[0335] Periodic time domain parameter (periodicTimeRsrc) =

[0336] {

[0337] Period / Offset (periodicityAndOffset) (time domain period parameters, including period value and offset);

[0338] Symbol Offset (symbolOffset) (the offset relative to the start position of a time slot);

[0339] The number of symbols (durationInSymbols).

[0340] }

[0341] For example, a parameter (such as period / offset, SlotPeriodicityAndSlotOffset configures a value) can be configured in a part of the beam resources to indicate that the beam resources are used for uplink transmission.

[0342] Two parameters (such as symbol offset symbolOffset and symbol duration durationInSymbols) can be configured in a part of the beam resources to indicate that the beam resources are used for downlink transmission.

[0343] For another example, a parameter (such as period / offset, SlotPeriodicityAndSlotOffset configures a value) can be configured in a part of the beam resources to indicate that the beam resources are used for downlink transmission.

[0344] Two parameters (such as symbol offset symbolOffset and symbol duration durationInSymbols) can be configured in a part of the beam resources to indicate that the beam resources are used for uplink transmission.

[0345] The method for indicating the forwarding link beam provided in the present application indicates that each beam resource is used for uplink or downlink transmission through the number of parameters in the beam resource, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0346] In some embodiments, the beam indication information includes a semi-static activation command of a beam resource;

[0347] The determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0348] It is determined that the beam resources whose logical channel identifier corresponding to the semi-static activation command is a first identifier are used for uplink transmission, and the beam resources whose logical channel identifier corresponding to the semi-static activation command is a second identifier are used for downlink transmission.

[0349] Specifically, in an embodiment of the present application, a semi-static activation command (or deactivation) of a beam resource is used to indicate that each beam resource is used for uplink or downlink transmission.

[0350] For example, different logical channel number identifiers (LCID values) are used to indicate that the beam resource is used for uplink or downlink transmission. For FDD scenarios, the logical channel number identifier code point 223 indicates that the beam resource is used for uplink transmission, and the logical channel number identifier code point 224 indicates that the beam resource is used for downlink transmission.

[0351] The method for indicating the forwarding link beam provided in the present application indicates that each beam resource is used for uplink or downlink transmission through a logical channel identifier, thereby realizing beamforming of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0352] In some embodiments, the beam indication information includes a semi-static activation command of a beam resource;

[0353] The determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0354] It is determined that the beam resources whose indication field information in the semi-static activation command is a first value are used for uplink transmission, and the beam resources whose indication field information in the semi-static activation command is a second value are used for downlink transmission.

[0355] Specifically, in an embodiment of the present application, a semi-static activation command of a beam resource indicates that each beam resource is used for uplink or downlink transmission.

[0356] Figure 4 is a schematic diagram of MAC-CE provided in an embodiment of the present application, such as Figure 4 As shown, the (reserved) bit R1 in the MAC-CE activation command is used to indicate that the beam resources activated this time are used for uplink or downlink transmission.

[0357] For example, for the FDD scenario, when the R1 value is 0, it means that the beam resources activated / deactivated by this MAC-CE are used for uplink transmission; when the R1 value is 1, it means that the beam resources activated / deactivated by this MAC-CE are used for downlink transmission; or, when the R1 value is 0, it means that the beam resources activated / deactivated by this MAC-CE are used for downlink transmission; when the R1 value is 1, it means that the beam resources activated / deactivated by this MAC-CE are used for uplink transmission.

[0358] The method for indicating the forwarding link beam provided in the present application indicates that each beam resource is used for uplink or downlink transmission through the (reserved) bit R1 in the MAC-CE activation command, thereby realizing beam forming of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0359] In some embodiments, the beam indication information includes a dynamic scheduling command of beam resources;

[0360] The determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0361] It is determined that the beam resources whose indication field information in the dynamic scheduling command is a first value are used for uplink transmission, and the beam resources whose indication field information in the dynamic scheduling command is a second value are used for downlink transmission.

[0362] Specifically, in an embodiment of the present application, a dynamic scheduling command is used to indicate whether each beam resource is used for uplink or downlink transmission.

[0363] In the DCI used for dynamic scheduling, a 1-bit or 2-bit indication may be used to indicate whether the current DCI transmission is for uplink or downlink transmission.

[0364] For example, the field UplinkDownlink indicator is added to DCI format 2_8, and the field occupies 1 bit or 2 bits. The value of UplinkDownlink indicator is 0, indicating that the scheduled beam resources are used for uplink transmission, and the value of UplinkDownlink indicator is 1, indicating that the scheduled beam resources are used for downlink transmission.

[0365] For another example, the field UplinkDownlink indicator is added to DCI format 2_8, and the field occupies 1 bit or 2 bits. The value of UplinkDownlink indicator is 0, indicating that the scheduled beam resources are used for downlink transmission, and the value of UplinkDownlink indicator is 1, indicating that the scheduled beam resources are used for uplink transmission.

[0366] The method for indicating the forwarding link beam provided in the present application indicates that each beam resource is used for uplink or downlink transmission through the indication field information in the dynamic scheduling command, thereby realizing the beam forming of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0367] In some embodiments, the beam indication information includes a dynamic scheduling command of beam resources;

[0368] The determining, based on the beam indication information, that one or more beam resources configured by the network device are used for uplink or downlink transmission includes:

[0369] Determine a target beam resource scheduled by the dynamic scheduling command; the target beam resource is at least one beam resource among the one or more beam resources configured by the network device;

[0370] The target beam resource is determined to be used for uplink or downlink transmission based on one or more predefined beam resources configured by the network device for uplink or downlink transmission.

[0371] In some embodiments, the Nth beam resource among the one or more beam resources configured by the network device is used for uplink transmission, and the N+1th beam resource among the one or more beam resources configured by the network device is used for downlink transmission; or,

[0372] The Nth beam resource among the one or more beam resources configured by the network device is used for downlink transmission, and the N+1th beam resource among the one or more beam resources configured by the network device is used for uplink transmission;

[0373] Wherein, N is a positive integer.

[0374] Specifically, in an embodiment of the present application, a dynamic scheduling command is used to indicate whether each beam resource is used for uplink or downlink transmission.

[0375] The Nth beam resource among one or more beam resources configured by the network device can be predefined or configured in advance for uplink transmission, and the N+1th beam resource among one or more beam resources configured by the network device can be used for downlink transmission, or vice versa.

[0376] After receiving the dynamic scheduling command, the NCR determines the target beam resource scheduled by the dynamic scheduling command, and based on which beam resource the target beam resource corresponds to, determines whether the target beam resource is used for uplink or downlink transmission.

[0377] The method for indicating the forwarding link beam provided in the present application can determine whether the target beam resource is used for uplink or downlink transmission through the position or identifier of the target beam resource scheduled by the dynamic scheduling command, thereby realizing the beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0378] In some embodiments, the 1st to Nth beam resources of the one or more beam resources configured by the network device are used for uplink transmission, and the N+1th to the last beam resources of the one or more beam resources configured by the network device are used for downlink transmission; or,

[0379] The first to Nth beam resources among the one or more beam resources configured by the network device are used for downlink transmission, and the N+1th to the last beam resources among the one or more beam resources configured by the network device are used for uplink transmission;

[0380] Wherein, N is a positive integer.

[0381] Specifically, in an embodiment of the present application, a dynamic scheduling command is used to indicate whether each beam resource is used for uplink or downlink transmission.

[0382] It can be predefined or configured in advance by the network device, so that the 1st to Nth beam resources among the one or more beam resources configured by the network device are used for downlink transmission, and the N+1th to the last beam resources among the one or more beam resources configured by the network device are used for uplink transmission; or vice versa.

[0383] After receiving the dynamic scheduling command, the NCR determines the target beam resource scheduled by the dynamic scheduling command, and based on which beam resource the target beam resource corresponds to, determines whether the target beam resource is used for uplink or downlink transmission.

[0384] For example, the 1st to M / 2nd beam resources are used for uplink transmission, and the M / 2nd to Mth beam resources are used for downlink transmission, where M is the total number of beam resources and M is an even number. After receiving the dynamic scheduling command, the NCR determines that the scheduled beam resource is the M / 2-1th beam resource, and can determine that it is used for uplink transmission.

[0385] The method for indicating the forwarding link beam provided in the present application can determine whether the target beam resource is used for uplink or downlink transmission through the position or identifier of the target beam resource scheduled by the dynamic scheduling command, thereby realizing the beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.

[0386] In some embodiments, the beam indication information includes a dynamic scheduling command of beam resources;

[0387] The dynamic scheduling command is also used to indicate grouping information of one or more beam resources configured by the network device;

[0388] Each beam resource in the first group is used for uplink transmission, and each beam resource in the second group is used for downlink transmission.

[0389] Specifically, in an embodiment of the present application, in an embodiment of the present application, a dynamic scheduling command is used to indicate that each beam resource is used for uplink or downlink transmission.

[0390] The dynamic scheduling command is used to schedule the target beam resources used by the NCR on the forwarding link.

[0391] The dynamic scheduling command is also used to indicate the grouping information of one or more beam resources configured by the network device, wherein each beam resource in the first group is used for uplink transmission, and each beam resource in the second group is used for downlink transmission.

[0392] After receiving the dynamic scheduling command, the NCR first determines which group the target beam resource scheduled by the dynamic scheduling command belongs to. Based on the corresponding group of the target beam resource, it can determine whether the target beam resource is used for uplink or downlink transmission.

[0393] For example, two groups of beam resources and beamindex are indicated, one group is for uplink and the other group is for downlink.

[0394] BeamNumforupink(X) / / Used for uplink, indicating the number of beam / time domain resources indicated by DCI.

[0395] Multiple beam index indications: Beamindex 1, Beamindex 2, …, Beamindex X.

[0396] Multiple time resource indications: Time resource indication 1, Time resource indication 2,…, Time resource indication X.

[0397] BeamNumfordownlink(Y) / / Used for downlink, indicating the number of beam / time domain resources indicated by DCI.

[0398] Multiple beam index indications: Beamindex 1, Beamindex 2, …, Beamindex Y.

[0399] Multiple time domain resource indications: Time resource indication 1, Time resource indication 2,…, Time resource indication Y.

[0400] Here, X+Y is less than the threshold configured by the base station. In this way, the base station can flexibly indicate the number of uplink and downlink beam indications while ensuring that the total bit length of the DCI information remains unchanged or is controlled within a certain range.

[0401] The method for indicating the forwarding link beam provided in the present application determines whether the target beam resource is used for uplink or downlink transmission through the group of target beam resources scheduled by the dynamic scheduling command, thereby realizing beam shaping of the forwarding link in the FDD scenario and improving the receiving performance of the terminal.
