[0111] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0112] In some embodiments, the network device can configure a downlink subband for the terminal on a downlink time domain unit or on a flexible time domain unit. These time domain units configured with downlink subbands can be called subband full-duplex (SBFD) time domain units, and time domain units that are not configured with uplink subbands and / or downlink subbands can be called non-SBFD (also called non-SBFD) time domain units.

[0113] In some embodiments, the network device can configure a downlink sub-band for the terminal on the uplink time domain unit or on the flexible time domain unit. These time domain units configured with downlink sub-bands can be called subband full-duplex (SBFD) time domain units, and time domain units not configured with downlink sub-bands can be called non-SBFD (also called non-SBFD) time domain units.

[0114] The present disclosure does not limit the time domain unit, and for example, it may include at least one of the following: frame, subframe, time slot, symbol, and sub-slot.

[0115] The network device can receive information sent by the terminal in the uplink subband of the SBFD time domain unit, and can send information to the terminal in the frequency domain resources outside the uplink subband corresponding to the SBFD time domain unit, so that the network device can achieve full-duplex communication in the SBFD time domain unit.

[0116] In some embodiments, the network device and the terminal may communicate based on a beam.

[0117] For example, a network device configures an uplink subband for a first terminal in some downlink time domain units, but does not configure an uplink subband for a second terminal in these downlink time domain units. The first terminal can perform uplink communication in the uplink subband in these downlink time domain units, but the second terminal can only perform downlink communication in these downlink time domain units. This may cause interference between the uplink communication of the first terminal and the downlink communication of the second terminal. To avoid such interference, the first terminal can adjust the beam (for example, the transmit beam).

[0118] In the downlink time domain unit not configured with the uplink subband, the first terminal and the second terminal only perform downlink communication, so the above-mentioned interference does not exist. Therefore, in the downlink time domain unit, the first terminal does not need to adjust the beam to avoid interference.

[0119] For network devices, since they can perform both uplink and downlink communications in SBFD time domain units and only downlink communications in non-SBFD time domain units, in order to adapt to different communication situations in SBFD time domain units and non-SBFD time domain units, network devices can use different beams in SBFD time domain units and non-SBFD time domain units.

[0120] It can be seen that when SBFD technology is introduced, the beams used by network devices and terminals to communicate on the SBFD time domain unit may be different from the beams used to communicate on the SBFD time domain unit. Different beams correspond to different spatial relationships (SpatialRelation). Therefore, it is necessary to independently determine the spatial relationship used when communicating on the SBFD time domain unit.

[0121] FIG2 is an interactive schematic diagram illustrating a relationship determination method according to an embodiment of the present disclosure.

[0122] As shown in FIG2 , the relationship determination method may include the following steps:

[0123] In step S201, the terminal determines a first spatial relationship of first information on a sub-band full-duplex SBFD time domain unit and / or a second spatial relationship on a non-SBFD time domain unit according to first indication information or a predefined rule.

[0124] In some embodiments, the first information may include, for example, uplink information and / or uplink channels, such as a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), and a sounding reference signal (SRS). Taking the example of the first information including PUCCH, the first information resource may be a PUCCH resource.

[0125] In some embodiments, the first information may include, for example, downlink information and / or downlink channels, such as a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), and a channel state information reference signal (CSI-RS). Taking the example of the first information including the PDCCH, the first information resource may be a PDCCH resource.

[0126] In step S202, the terminal transmits first information in SBFD time domain units based on the first spatial relationship, and / or transmits the first information in non-SBFD time domain units based on the second spatial relationship.

[0127] According to an embodiment of the present disclosure, the terminal can determine the first spatial relationship of the first information on the SBFD time domain unit based on the first indication information sent by the network device, or a predefined rule, without having to follow the first spatial relationship of the first information on the non-SBFD time domain unit. Accordingly, the terminal can communicate on the first information based on different spatial relationships in the SBFD time domain unit and the non-SBFD time domain unit, so as to avoid interference between uplink communication and downlink communication when communicating on the SBFD time domain unit.

[0128] The following uses several embodiments to exemplarily illustrate how the terminal determines the first spatial relationship of the first information on the SBFD time domain unit according to the first indication information.

[0129] In some embodiments, the first indication information includes at least one of the following: Radio Resource Control (RRC) signaling; Downlink Control Information (DCI); and Media Access Control Control Element (MAC CE).

[0130] In some embodiments, the MAC CE includes one of the following: a traditional MAC CE; a newly defined MAC CE.

[0131] Exemplarily, the legacy MAC CE may be a MAC CE with the same LCID number as that of the existing PUCCH spatial relation Activation / Deactivation MAC CE or the existing Enhanced PUCCH Spatial Relation Activation / Deactivation MAC CE.

[0132] In some embodiments, a newly defined MAC CE is used to indicate at least one of the following:

[0133] activated spatial relationship information, wherein the activated spatial relationship information is used to determine the first spatial relationship;

[0134] The first spatial relationship is offset relative to a second spatial relationship of the first information in a non-subband full-duplex non-SBFD time domain unit, wherein the spatial relationship offset and the second spatial relationship are used to determine the first spatial relationship.

[0135] In some embodiments, regarding legacy MAC CEs and newly defined MAC CEs, to facilitate differentiation by the terminal, the network device may send the legacy MAC CEs and the newly defined MAC CEs based on different logical channels (LCs). In this case, the logical channel identifier of the newly defined MAC CE is different from the logical channel identifier (LCID) of the legacy MAC CE. Therefore, the terminal can differentiate between the legacy MAC CEs and the newly defined MAC CEs based on the logical channel identifier of the MAC CE, thereby correctly parsing the legacy MAC CEs and the newly defined MAC CEs.

[0136] FIG3A is a schematic structural diagram of a MAC CE according to an embodiment of the present disclosure.

[0137] As shown in FIG3A , a conventional MAC CE, eg, a PUCCH spatial relation Activation / Deactivation MAC CE, may include multiple bytes (Oct), for example, may include 3 bytes, namely, Oct1, Oct2, and Oct3.

[0138] Oct1 can include 3 information fields: R, Serving Cell ID, BWP ID. Oct2 can include 2 information fields: R, PUCCH resource ID. Oct3 can include information field S i , for example, i in FIG. 3A can be equal to 0 to 7.

[0139] Where R represents a reserved bit; Serving Cell ID is used to indicate the serving cell to which MAC CE is applied; BWP ID is used to indicate the bandwidth part (BandWidth Part, BWP) applied by MAC CE; PUCCH resource ID is used to indicate the PUCCH resource applied by MAC CE; S i is the spatial relationship number, which is used to indicate the activated spatial relationship, where S i There is a one-to-one correspondence between the spatial relationships in the spatial relationship table. If S i =1, indicating that the i+1th spatial relationship in the spatial relationship table is activated.

[0140] In some embodiments, the spatial relationship corresponding to SBFD can be indicated based on a newly defined MAC CE. The structure of the newly defined MAC CE can be the same as the structure of the traditional MAC CE shown in Figure 3A, but the LCID of the newly defined MAC CE can be different from the LCID of the traditional MAC CE, so that the terminal can distinguish the newly defined MAC CE from the traditional MAC CE based on the LCID.

[0141] For example, the newly defined information field S in MAC CE i The activated spatial relationship indicated in the spatial relationship table may serve as the first spatial relationship and / or the second spatial relationship.

[0142] For example, the newly defined information field S in MAC CE i The spatial relationship offset of the first spatial relationship relative to the second spatial relationship (for example, the offset of the spatial relationship identifier) ​​can be indicated, and the terminal can determine the second spatial relationship based on the traditional MAC CE, and then determine the first spatial relationship based on the second spatial relationship and the spatial relationship offset.

[0143] It should be noted that the spatial relationship table can be configured by the network device (for example, spatialRelationInfoToAddModList configured by PUCCH-config) or agreed upon by the protocol. The spatial relationship table can be a traditional spatial relationship table or a spatial relationship table specific to an SBFD terminal or SBFD time domain unit. This disclosure does not limit this.

[0144] FIG3B is a schematic structural diagram of another traditional MAC CE according to an embodiment of the present disclosure.

[0145] As shown in FIG3B , a conventional MAC CE, eg, Enhanced PUCCH Spatial Relation Activation / Deactivation MAC CE, may include multiple bytes (Oct), for example, 2N-1 bytes, namely Oct1, Oct2, Oct3, ..., Oct(2N-1), and the MAC CE includes N-1 PUCCH resource IDs.

[0146] Oct1 can include three information fields: R, Serving Cell ID, and BWP ID. The Oct following Oct1 can be divided into two types, for example, Octi and Oct(i+1). Octi can include two information fields: R and PUCCH resource ID; Oct(i+1) can include three information fields: R, R, and SpatialRelationInfoID.

[0147] Among them, R represents a reserved bit; Serving Cell ID is used to indicate the serving cell applied by MAC CE; BWP ID is used to indicate the BWP applied by MAC CE; PUCCH resource ID is used to indicate the PUCCH resource applied by MAC CE; SpatialRelationInfoID in Oct(i+1) is the activated spatial relationship identifier, which is used to indicate the activated spatial relationship, and the activated spatial relationship can be used as the spatial relationship of the PUCCH transmitted in the PUCCH resource corresponding to the PUCCH resource ID in Octi.

[0148] The conventional MAC CE shown in FIG3A may be a PUCCH spatial relation activation / deactivation MAC CE (spatial relation Activation / Deactivation MAC CE), and the corresponding LCID is 49. The conventional MAC CE shown in FIG3B may be an enhanced PUCCH Spatial Relation Activation / Deactivation MAC CE (enhanced PUCCH Spatial Relation Activation / Deactivation MAC CE), and the corresponding LCID is 313.

[0149] In some embodiments, the spatial relationship corresponding to SBFD can be indicated based on a newly defined MAC CE. The structure of the newly defined MAC CE can be the same as the structure of the traditional MAC CE shown in Figure 3B, but the LCID of the newly defined MAC CE can be different from the LCID of the traditional MAC CE, so that the terminal can distinguish the newly defined MAC CE from the traditional MAC CE based on the LCID.

[0150] For example, the activated spatial relationship indicated by the information field SpatialRelationInfoID in the newly defined MAC CE may be used as the first spatial relationship and / or the second spatial relationship.

[0151] For example, the information field SpatialRelationInfoID in the newly defined MAC CE can indicate the spatial relationship offset of the first spatial relationship relative to the second spatial relationship (for example, the offset of the spatial relationship identifier). The terminal can determine the second spatial relationship based on the traditional MAC CE, and then determine the first spatial relationship based on the second spatial relationship and the spatial relationship offset.

[0152] FIG3C is a schematic structural diagram of another MAC CE according to an embodiment of the present disclosure.

[0153] As shown in Figure 3C, the newly defined MAC CE may include multiple bytes (Oct), for example, four bytes, namely Oct1, Oct2, Oct3, and Oct4. In this embodiment, the newly defined MAC CE may indicate two spatial relationships, one of which may be used as a first spatial relationship, and the other may be used as a second spatial relationship.

[0154] Oct1 can include 3 information fields: R, Serving Cell ID, BWP ID. Oct2 can include 2 information fields: R, PUCCH resource ID. Oct3 and Oct4 can include information fields S i , for example, i in FIG. 3C can be equal to 0 to 7.

[0155] Where R represents a reserved bit; Serving Cell ID is used to indicate the serving cell to which MAC CE is applied; BWP ID is used to indicate the bandwidth part (BandWidth Part, BWP) applied by MAC CE; PUCCH resource ID is used to indicate the PUCCH resource applied by MAC CE; S i is the spatial relationship number, which is used to indicate the activated spatial relationship, where S i There is a one-to-one correspondence between the spatial relationships in the spatial relationship table. If S i =1, indicating that the i+1th spatial relationship in the spatial relationship table is activated.

[0156] The difference from the traditional MAC CE shown in FIG3A is that in the newly defined MAC CE shown in FIG3C , there are two bytes containing the information field S i , based on this MAC CE structure, S in one byte i The indicated activated spatial relationship may be the spatial relationship of the first information on the SBFD time domain unit, and the S in another byte may be the spatial relationship of the first information on the SBFD time domain unit. i The indicated activated spatial relationship may be a spatial relationship of the first information in a non-SBFD time domain unit.

[0157] For example, S in Oct3 i It can indicate the spatial relationship of PUCCH in non-SBFD time domain unit. i It can indicate the spatial relationship of PUCCH on the SBFD time domain unit. Among them, PUCCH is transmitted on the PUCCH resource indicated by the PUCCH resource ID in Oct2.

[0158] In addition, in some embodiments, S iThe spatial relationship offset SpatialRelationInfoOffset indicating the first spatial relationship relative to the reference relationship, for example, the reference spatial relationship may be a second spatial relationship of the first information in a non-SBFD time domain unit, or a predefined spatial relationship.

[0159] For example, S in Oct3 i It can indicate the second spatial relationship of PUCCH on the non-SBFD time domain unit, S in Oct4 i The spatial relationship offset of the first spatial relationship of the PUCCH on the non-SBFD time domain unit relative to the second spatial relationship may be indicated, and the terminal may determine the first spatial relationship based on the second spatial relationship and the spatial relationship offset.

[0160] FIG3D is a schematic structural diagram of another MAC CE according to an embodiment of the present disclosure.

[0161] As shown in Figure 3D, the traditional MAC CE may include multiple bytes (Oct), for example, it may include 3N-1 bytes, namely Oct1, Oct2, Oct3, ..., Oct(3N-1), and the MAC CE includes N-1 PUCCH resource IDs. In this embodiment, the newly defined MAC CE can indicate two spatial relationships, one of which can be used as the first spatial relationship, and the other spatial relationship can be used as the second spatial relationship.

[0162] Oct1 can include three information fields: R, Serving Cell ID, and BWP ID. The Octs following Oct1 can be divided into three types, such as Octi, Oct(i+1), and Oct(i+2). Octi can include two information fields: R and PUCCH resource ID; Oct(i+1) can include three information fields: R, R, and SpatialRelationInfoID; and Oct(i+2) can include three information fields: R, R, and SpatialRelationInfoID.

[0163] Among them, R represents a reserved bit; Serving Cell ID is used to indicate the serving cell applied by MAC CE; BWP ID is used to indicate the BWP applied by MAC CE; PUCCH resource ID is used to indicate the PUCCH resource applied by MAC CE.

[0164] The difference from the traditional MAC CE shown in FIG3B is that in the newly defined MAC CE shown in FIG3D , the PUCCH resource ID in one byte is associated with the SpatialRelationInfoID in two bytes.

[0165] For example, the SpatialRelationInfoID in Oct(i+1) is an activated spatial relationship identifier, which is used to indicate the activated spatial relationship, and the activated spatial relationship can be used as the spatial relationship of the PUCCH transmitted in the non-SBFD time domain unit in the PUCCH resource corresponding to the PUCCH resource ID in Octi; the SpatialRelationInfoID in Oct(i+2) is an activated spatial relationship identifier, which is used to indicate the activated spatial relationship, and the activated spatial relationship can be used as the spatial relationship of the PUCCH transmitted in the SBFD time domain unit in the PUCCH resource corresponding to the PUCCH resource ID in Octi.

[0166] In addition, in some embodiments, the spatial relationship offset SpatialRelationInfoOffset of the first spatial relationship relative to the reference relationship can also be indicated by SpatialRelationInfo. For example, the reference spatial relationship can be the second spatial relationship of the first information in the non-SBFD time domain unit, or a predefined spatial relationship.

[0167] For example, the SpatialRelationInfoID in Oct(i+1) is an activated spatial relationship identifier, which is used to indicate the activated spatial relationship, and the activated spatial relationship can be used as the second spatial relationship of the PUCCH transmitted in the non-SBFD time domain unit in the PUCCH resource corresponding to the PUCCH resource ID in Octi; the SpatialRelationInfoID in Oct(i+2) is an activated spatial relationship identifier, which is used to indicate the spatial relationship offset of the first spatial relationship of the PUCCH in the non-SBFD time domain unit relative to the second spatial relationship. Then the terminal can determine the first spatial relationship based on the second spatial relationship and the spatial relationship offset.

[0168] It should be noted that, in the above embodiment, the proportion of MAC CE may be fixed (for example, always 32 bits) or not fixed, and the present disclosure does not limit this.

[0169] In some embodiments, the spatial relationship offset is used to indicate an offset of the identifier of the first spatial relationship relative to the identifier of the second spatial relationship.

[0170] For example, in FIG. 3C and FIG. 3D above, the spatial relationship offset may be S in MAC CE. i , SpatialRelationInfo, and other information fields. In some embodiments, the spatial relationship offset may indicate the specific spatial relationship offset of the first spatial relationship relative to the second spatial relationship, and may also indicate the offset of the identifier of the first spatial relationship relative to the identifier of the second spatial relationship. For example, if the terminal determines that the identifier of the second spatial relationship is SpatialRelationInfoID=2, and the offset of the identifier of the first spatial relationship relative to the identifier of the second spatial relationship is 1, then the terminal may determine that the first spatial relationship is SpatialRelationInfoID=2+1, that is, SpatialRelationInfoID=3.

[0171] In some embodiments, a new MAC CE is defined to indicate the first spatial relationship and the second spatial relationship.

[0172] In some embodiments, the relationship determination method further includes at least one of the following:

[0173] Ignore traditional MAC CE;

[0174] Updating a second spatial relationship of the first information on the non-SBFD time domain unit according to the traditional MAC CE;

[0175] updating the first spatial relationship and the second spatial relationship according to the traditional MAC CE;

[0176] In response to receiving the newly defined MAC CE, no legacy MAC CE is expected to be received.

[0177] In some embodiments, the newly defined MAC CE may not only indicate the first spatial relationship of the first information in the SBFD time domain unit, but also indicate the second spatial relationship of the first information in the non-SBFD time domain unit.

[0178] In this case, since the newly defined MAC CE indicates the first spatial relationship and the second spatial relationship, the traditional MAC CE for indicating the second spatial relationship can be ignored by the terminal, so as to save terminal resources.

[0179] It should be noted that the terminal ignores the traditional MAC CE, which may mean that after receiving the traditional MAC CE, the terminal ignores the information bits used to indicate the second spatial relationship in the traditional MAC CE, while the information bits used to indicate other information can be parsed as usual.

[0180] In some embodiments, the newly defined MAC CE may not only indicate the first spatial relationship of the first information in the SBFD time domain unit, but also indicate the second spatial relationship of the first information in the non-SBFD time domain unit.

[0181] In this case, if the terminal receives a legacy MAC CE, the terminal may update the second spatial relationship based on the legacy MAC CE. For example, if the terminal receives a legacy MAC CE after receiving a newly defined MAC CE, the activated spatial relationship indicated in the legacy MAC CE may be used as the latest second spatial relationship. The first spatial relationship remains unchanged or is deactivated.

[0182] In some embodiments, the newly defined MAC CE may not only indicate the first spatial relationship of the first information in the SBFD time domain unit, but also indicate the second spatial relationship of the first information in the non-SBFD time domain unit.

[0183] In this case, if the terminal receives a traditional MAC CE, the terminal can update the first spatial relationship and the second spatial relationship based on the traditional MAC CE. For example, if the terminal receives a traditional MAC CE after receiving a newly defined MAC CE, the first spatial relationship and the second spatial relationship can be updated according to the activated spatial relationship indicated in the traditional MAC CE.

[0184] In some embodiments, the newly defined MAC CE may not only indicate the first spatial relationship of the first information in the SBFD time domain unit, but also indicate the second spatial relationship of the first information in the non-SBFD time domain unit.

[0185] In this case, since the newly defined MAC CE indicates the first spatial relationship and the second spatial relationship, the terminal may not expect to receive the traditional MAC CE. Accordingly, the network device may not send the traditional MAC CE to the terminal in order to save communication resources.

[0186] In another possible implementation manner, the terminal may determine the first spatial relationship and the second spatial relationship based on a traditional MAC CE. Exemplarily, the traditional MAC CE may be a MAC CE having the same LCID number as an existing MAC CE indicating a spatial relationship.

[0187] The following uses several embodiments to exemplify how the terminal determines the first spatial relationship of the first information on the SBFD time domain unit according to the traditional MAC CE.

[0188] In some embodiments, in response to the terminal being a terminal supporting SBFD, the terminal determines that the traditional MAC CE is used to indicate the first spatial relationship and the second spatial relationship; or, determines that the traditional MAC CE is used to indicate the first spatial relationship and the second spatial relationship based on the first information field of the traditional MAC CE.

[0189] Because based on the traditional MAC CE, only one spatial relationship can be activated for the same PUCCH resource, but based on the newly defined MAC CE, two spatial relationships can be activated for the same PUCCH resource.

[0190] In this implementation, the traditional MAC CE can be enhanced to indicate both the first and second spatial relationships. However, both SBFD-supporting terminals and non-SBFD-supporting legacy terminals can receive the traditional MAC CE. However, the traditional MAC CE may have different functions for SBFD-supporting terminals and legacy terminals. For example, the traditional MAC CE may indicate the first and second spatial relationships for SBFD-supporting terminals, while only indicating the second spatial relationship for legacy terminals. Therefore, it is necessary to enable SBFD-supporting terminals to distinguish the functions of the traditional MAC CE.

[0191] For example, when the terminal is a terminal that supports SBFD, the MAC CE sent by the network device to the terminal can be used to indicate (for example, activate) two spatial relationships, for example, one corresponding to the first spatial relationship and the other corresponding to the second spatial relationship; or, for a terminal that supports SBFD, the MAC CE sent by the network device to the terminal only has traditional functions, for example, it is only used to indicate (for example, activate) one spatial relationship, for example, as the second spatial relationship.

[0192] When the terminal is a traditional terminal, the MAC CE sent by the network device to the terminal is used to indicate (eg, activate) a spatial relationship, such as the second spatial relationship.

[0193] For example, the terminal may distinguish the function of the MAC CE based on the first information field in the traditional MAC CE, wherein the first information field may be any information in the MAC CE, such as a reserved bit, and the present disclosure does not limit this.

[0194] Taking the first information field including a reserved bit as an example, for example, if the reserved bit indication value is 1, the terminal can determine that the traditional MAC CE activates two spatial relationships, or the activated spatial relationship can correspond to the SBFD time domain unit and the non-SBFD time domain unit; for example, if the reserved bit indication value is 0, the terminal can determine that the traditional MAC CE only activates one spatial relationship, or the activated spatial relationship only corresponds to the SBFD time domain unit.

[0195] Regarding a spatial relationship where only traditional MAC CE is activated, the terminal can determine the type of time domain unit corresponding to this spatial relationship based on network device indication or a predefined method. For example, this spatial relationship corresponds to the PUCCH of a non-SBFD time domain unit; for example, this spatial relationship corresponds to the PUCCH of a SBFD time domain unit; for example, this spatial relationship corresponds to the PUCCH of both non-SBFD and SBFD time domain units; for example, this spatial relationship corresponds to the time domain unit where the PUCCH resource is located in the MAC CE.

[0196] The following uses several embodiments to exemplarily illustrate the terminal's determination of two spatial relationships where traditional MAC CE is activated.

[0197] In some embodiments, the terminal determines a first spatial relationship identifier and a second spatial relationship identifier among multiple activated spatial relationship identifiers according to the relationship between the multiple activated spatial relationship identifiers in the traditional MAC CE. Among them, the multiple activated spatial relationship identifiers correspond to the same first information resource identifier. The first spatial relationship identifier is used to indicate the first spatial relationship, and the second spatial relationship identifier is used to indicate the second spatial relationship.

[0198] For example, taking the traditional MAC CE shown in Figure 3A as an example, there can be two S i with a value of 1. For example, in S i where S m and S n have values of l, and m and n belong to i, then it can indicate that the (m + 1)-th and (n + 1)-th spatial relationships in the spatial relationship table are activated. One of the spatial relationships is used as the first spatial relationship, and the other is used as the second spatial relationship.

[0199] For example, if m < n, the terminal determines that the spatial relationship activated by S m is the second spatial relationship. If m > n, the terminal determines that the spatial relationship activated by S m is the first spatial relationship.

[0200] For example, if m < n, the terminal determines that the spatial relationship activated by S m is the first spatial relationship. If m > n, the terminal determines that the spatial relationship activated by S m is the second spatial relationship.

[0201] For example, if m = n, the terminal determines that the spatial relationship activated by S m is the first spatial relationship, or the terminal determines that the spatial relationship activated by S m \nis the second spatial relationship, or the terminal determines that the spatial relationship activated by S m is the first and second spatial relationships, and the two spatial relationships are the same.

[0202] In some embodiments, the terminal determines multiple activated spatial relationship identifiers corresponding to multiple identical first information resource identifiers in a traditional MAC CE, and determines a first spatial relationship identifier and a second spatial relationship identifier among the multiple spatial relationship identifiers based on the relationship between the multiple activated spatial relationship identifiers, wherein the first spatial relationship identifier is used to indicate a first spatial relationship, and the second spatial relationship identifier is used to indicate a second spatial relationship.

[0203] For example, in the conventional MAC CE shown in Figure 3B , the MAC CE includes multiple PUCCH resource IDs, and the same PUCCH resource ID can exist among the multiple PUCCH resource IDs. For example, if the PUCCH resource IDs in byte 2 and byte 4 are the same, the terminal can determine that the spatial relationship indicated by the SpatialRelationInfoID corresponding to byte 2 and byte 4 is activated. This allows the conventional MAC CE to activate two spatial relationships, and the specific spatial relationship as the first spatial relationship and the spatial relationship as the second spatial relationship can be determined based on predefined rules or network device instructions.

[0204] For example, the predefined rule stipulates that of the two bytes, the SpatialRelationInfoID corresponding to the smaller byte is used as the second spatial relationship, and the SpatialRelationInfoID corresponding to the larger byte is used as the second spatial relationship. For example, if the SpatialRelationInfoID corresponding to byte 2 indicates spatial relationship #2, and the SpatialRelationInfoID corresponding to byte 4 indicates spatial relationship #4, then spatial relationship #2 can be used as the second spatial relationship, and spatial relationship #4 can be used as the first spatial relationship.

[0205] Of course, the predefined rule may also stipulate that of the two bytes, the spatial relationship activated by the SpatialRelationInfoID corresponding to the larger byte is used as the second spatial relationship, and the spatial relationship activated by the SpatialRelationInfoID corresponding to the smaller byte is used as the second spatial relationship.

[0206] In another possible implementation manner, the terminal may determine the first spatial relationship identifier and the second spatial relationship identifier based on the indication signaling.

[0207] For example, the information field R in the MAC CE may indicate two spatial relations activated by the MAC CE, one of which is a first spatial relation and the other is a second spatial relation. For example, for two identical PUCCH resource IDs, the spatial relation indicated by the SpatialRelationInfoID corresponding to the PUCCH resource ID with an R value of 1 is used as the first spatial relation, and the spatial relation indicated by the SpatialRelationInfoID corresponding to the PUCCH resource ID with an R value of 0 is used as the second spatial relation; or, the spatial relation indicated by the SpatialRelationInfoID corresponding to the PUCCH resource ID with an R value of 0 is used as the first spatial relation, and the spatial relation indicated by the SpatialRelationInfoID corresponding to the PUCCH resource ID with an R value of 1 is used as the second spatial relation.

[0208] The following uses several embodiments to exemplarily illustrate how a terminal determines the first spatial relationship of the first information on the SBFD time domain unit according to a predefined rule.

[0209] In some embodiments, in addition to being configured with a traditional second spatial relationship table, the terminal may also be configured with a first spatial relationship table for SBFD. In this case, the terminal may determine, in the first spatial relationship table, that the spatial relationship corresponding to the activated spatial relationship identifier is the first spatial relationship based on the spatial relationship identifier activated in the traditional MAC CE, and may also determine, in the second spatial relationship table, that the spatial relationship corresponding to the activated spatial relationship identifier is the second spatial relationship. Exemplarily, the terminal may determine, in the first spatial relationship table, that the spatial relationship corresponding to the activated spatial relationship identifier is the first spatial relationship based on a spatial relationship identifier activated in the traditional MAC CE, and may also determine, in the second spatial relationship table, that the spatial relationship corresponding to the activated spatial relationship identifier is the second spatial relationship.

[0210] The network device may configure or agree upon a first spatial relationship table specifically for SBFD for the terminal. The first spatial relationship table may be the same as or different from the traditional second spatial relationship table (for example, some or all of the spatial relationships in the table are different), and this disclosure does not limit this.

[0211] Based on this, after receiving the traditional MAC CE, the terminal supporting SBFD can determine in the first spatial relationship table that the spatial relationship corresponding to the activated spatial relationship identifier is the first spatial relationship according to the spatial relationship identifier activated in the traditional MAC CE, and determine in the second spatial relationship table that the spatial relationship corresponding to the activated spatial relationship identifier is the second spatial relationship according to the spatial relationship identifier activated in the traditional MAC CE.

[0212] However, after receiving the traditional MAC CE, the traditional terminal that does not support SBFD can determine, according to the activated spatial relationship identifier in the traditional MAC CE, in the second spatial relationship table that the spatial relationship corresponding to the activated spatial relationship identifier is the first spatial relationship.

[0213] For example, taking the traditional MAC CE shown in FIG3A as an example, after receiving the traditional MAC CE, the terminal supporting SBFD can i Determine the i+1th spatial relationship in the first spatial relationship table as the first spatial relationship, and according to S in the traditional MAC CE i The i+1th spatial relationship in the second spatial relationship table is determined to be the second spatial relationship.

[0214] For example, taking the traditional MAC CE shown in Figure 3B as an example, after the terminal supporting SBFD receives the traditional MAC CE, if the spatial relationship corresponding to SpatialRelationInfoID=1 of PUCCH resource#1 is activated, the terminal can determine, based on the SpatialRelationInfoID=1 in the traditional MAC CE, that the spatial relationship identified as SpatialRelationInfoID=1 in the first spatial relationship table is the first spatial relationship, and determine, based on the SpatialRelationInfoID=1 in the traditional MAC CE, that the spatial relationship identified as SpatialRelationInfoID=1 in the second spatial relationship table is the second spatial relationship.

[0215] The following uses several embodiments to exemplarily illustrate how a terminal determines the first spatial relationship of the first information on the SBFD time domain unit according to a predefined rule.

[0216] In some embodiments, the terminal determines a second spatial relationship of the first information in a non-SBFD time domain unit; and determines the first spatial relationship according to a mapping relationship between the first spatial relationship and the second spatial relationship and the second spatial relationship.

[0217] For example, the terminal may determine the second spatial relationship of the first information on the non-SBFD time domain unit based on a traditional method, for example, based on the MAC CE shown in FIG. 3A or the MAC CE shown in FIG. 3B , which will not be described in detail here.

[0218] The predefined rule may stipulate that the terminal determines the first spatial relationship based on the mapping relationship between the first spatial relationship and the second spatial relationship. Since the mapping relationship is known to the terminal, for example, the terminal determines the mapping relationship based on implementation, network instructions, or predefined rules (such as protocol agreements), and then after determining the second spatial relationship, the terminal can determine the first spatial relationship based on the second spatial relationship and the mapping relationship.

[0219] In some embodiments, the mapping relationship is configured by a network device, or is agreed upon by a protocol, or is determined by a terminal according to a mapping relationship of reference signals having a quasi co-location (QCL) relationship.

[0220] For example, the reference signal includes but is not limited to a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), and a sounding reference signal (SRS).

[0221] Taking SSB as a reference signal as an example, for example, the terminal determines based on the traditional method that the SSB associated with the spatial relationship corresponding to the SBFD time domain unit is SSB#3, and the SSB associated with the spatial relationship corresponding to the non-SBFD time domain unit is SSB#0, and then the terminal determines based on the predefined rules that SSB#0 is associated with SSB#3. Then, under the condition that the spatial relationship of the first information in the non-SBFD time domain unit is quasi-co-located with SSB#0, the terminal can determine that the spatial relationship of the first information in the SBFD time domain unit is quasi-co-located with SSB#3.

[0222] In some embodiments, the terminal determines a second spatial relationship of the first information on a non-SBFD time domain unit; determines a first offset of the second spatial relationship relative to the first spatial relationship based on the spatial relationship offset of the SBFD time domain unit relative to the non-SBFD time domain unit; and determines the first spatial relationship based on the first offset and the second spatial relationship.

[0223] For example, the spatial relationship offset of the SBFD time domain unit relative to the non-SBFD time domain unit can be determined based on the offset of the SpatialRelationInfoId corresponding to the SBFD time domain unit relative to the SpatialRelationInfoId corresponding to the non-SBFD time domain unit, or can be determined based on the offset of the reference signal ID corresponding to the SBFD time domain unit relative to the reference signal ID corresponding to the non-SBFD time domain unit.

[0224] For example, the terminal may determine a second spatial relationship of the first information in a non-SBFD time domain unit, such as the spatial relationship indicated by SpatialRelationInfoId=1, and the offset of the SpatialRelationInfoId corresponding to the SBFD time domain unit relative to the SpatialRelationInfoId corresponding to the non-SBFD time domain unit is, for example, 2. Then, the terminal may determine that the first offset of the second spatial relationship relative to the first spatial relationship is also 2. Furthermore, based on the first offset of 2 and SpatialRelationInfoId=1, the terminal may determine that the first spatial relationship is SpatialRelationInfoId=(1+2), that is, the spatial relationship corresponding to SpatialRelationInfoId=3.

[0225] For example, the terminal may determine a second spatial relationship of the first information on a non-SBFD time domain unit, such as the spatial relationship indicated by SpatialRelationInfoId=1, and the reference signal SSB corresponding to the SBFD time domain unit is SSB#2, the reference signal SSB corresponding to the non-SBFD time domain unit is SSB#1, and the offset of the reference signal ID is 1. Then, the terminal may determine that the first offset of the second spatial relationship relative to the first spatial relationship is also 1. Furthermore, based on the first offset 2 and SpatialRelationInfoId=1, the terminal may determine that the first spatial relationship is SpatialRelationInfoId=(1+2), that is, the spatial relationship corresponding to SpatialRelationInfoId=3.

[0226] It should be noted that the spatial relationship offset of the SBFD time domain unit relative to the non-SBFD time domain unit can be determined autonomously by the terminal, agreed upon by the protocol, or indicated by the network device, such as through RRC, DCI, MAC CE, etc., and this disclosure does not limit this.

[0260] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0261] In some embodiments, the first indication information includes at least one of the following: radio resource control RRC signaling; downlink control information DCI; media access control layer control element MAC CE.

[0262] In some embodiments, the MAC CE includes one of the following: a traditional MAC CE; a newly defined MAC CE.

[0263] In some embodiments, a newly defined MAC CE is used to indicate at least one of the following:

[0264] activated spatial relationship information, wherein the activated spatial relationship information is used to determine the first spatial relationship;

[0265] The first spatial relationship is offset relative to a second spatial relationship of the first information in a non-subband full-duplex non-SBFD time domain unit, wherein the spatial relationship offset and the second spatial relationship are used to determine the first spatial relationship.

[0266] In some embodiments, the spatial relationship offset is used to indicate an offset of the identifier of the first spatial relationship relative to the identifier of the second spatial relationship.

[0267] In some embodiments, the terminal is a terminal supporting SBFD, wherein the traditional MAC CE is used to update the second spatial relationship of the first information on the non-SBFD time domain unit; or, the traditional MAC CE is used to update the first spatial relationship and the second spatial relationship.

[0268] In some embodiments, a new MAC CE is defined to indicate the first spatial relationship and the second spatial relationship.

[0269] In some embodiments, the logical channel identifier of the newly defined MAC CE is different from the logical channel identifier of the traditional MAC CE.

[0270] In some embodiments, a conventional MAC CE is used to indicate a first spatial relationship and a second spatial relationship of the first information on a non-SBFD time domain unit.

[0271] In some embodiments, in response to the terminal being a terminal supporting SBFD, it is determined that the traditional MAC CE is used by the terminal to determine the first spatial relationship and the second spatial relationship; or, the first information field of the traditional MAC CE is used by the terminal to determine that the traditional MAC CE is used to indicate the first spatial relationship and the second spatial relationship.

[0272] In some embodiments, the relationship between multiple activated spatial relationship identifiers in a traditional MAC CE is used to determine a first spatial relationship identifier and a second spatial relationship identifier among multiple spatial relationship identifiers, wherein the multiple activated spatial relationship identifiers correspond to the same first information resource identifier, the first spatial relationship identifier is used to indicate a first spatial relationship, and the second spatial relationship identifier is used to indicate a second spatial relationship.

[0276] In some embodiments, the predefined rules include: determining a second spatial relationship of the first information on a non-SBFD time domain unit; determining a first offset of the second spatial relationship relative to the first spatial relationship based on the spatial relationship offset of the SBFD time domain unit relative to the non-SBFD time domain unit; and determining the first spatial relationship based on the first offset and the second spatial relationship.

[0277] The second aspect and the optional implementation of the optional embodiment of the second aspect can be referred to the optional implementation in the embodiment shown in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0278] In some embodiments, a terminal supporting SBFD, such as a Rel-18 or later version terminal, sends uplink information on a UL subband in a DL or flexible symbol based on network device configuration.

[0279] The embodiment of the present disclosure uses uplink information including PUCCH as an example to illustrate the solution. The technical solution of the present disclosure can also be applied to other uplink information such as PUSCH and SRS, which will not be elaborated in this disclosure.

[0280] Taking the uplink information including PUCCH as an example, considering the different spatial relationships between PUCCH in SBFD and non-SBFD, a corresponding scheme is designed to implement the spatial relationship indication of PUCCH in SBFD and non-SBFD. This is beneficial for the terminal to transmit PUCCH separately on different time unit types based on different spatial relationships. PUCCH corresponding to SBFD and non-SBFD can be transmitted based on the same PUCCH resource or based on different PUCCH resources, and this disclosure does not limit this.

[0281] Implementation method 1:

[0282] In some embodiments, based on the spatial relationship list configured by the terminal, eg, based on the spatialRelationInfoToAddModList configured by PUCCH-config, the terminal determines the spatial relationship corresponding to PUCCH on SBFD and non-SBFD based on the MAC CE indication.

[0283] Example 1:

[0284] Considering that the spatial relationships corresponding to the same PUCCH transmitted in SBFD and non-SBFD time units are different, unlike the traditional mechanism where the same PUCCH corresponds to the same spatial relationship in the same PUCCH resource, in SBFD scenarios, the same PUCCH can correspond to two spatial relationships. Accordingly, the embodiments of the present disclosure mainly consider introducing a new MAC CE to indicate the spatial relationship corresponding to the SBFD time unit.

[0285] For example, the LCID number corresponding to the newly introduced MAC CE and the existing MAC CE indicating the spatial relationship is different.

[0286] For example, the MAC CE for indicating the spatial relationship may include a PUCCH spatial relation Activation / Deactivation MAC CE (corresponding to an LCID number equal to 49) or an enhanced PUCCH Spatial Relation Activation / Deactivation MAC CE (corresponding to an eLCID index equal to 313).

[0287] Example 1-1:

[0288] The terminal determines the spatial relationship corresponding to the SBFD time unit based on the newly introduced MAC CE. The terminal determines that the MAC CE is a MAC CE indicating the spatial relationship corresponding to the SBFD based on the LCID number corresponding to the MAC CE.

[0289] The terminal determines the spatial relationship corresponding to the SBFD based on the activated spatial relationship number indicated by the MAC CE, eg, PUCCH-SpatialRelationInfoId, or the spatial relationship offset.

[0290] Exemplarily, the spatial relationship offset is equal to the offset between the spatial relationship number corresponding to the SBFD and the ID corresponding to the non-SBFD.

[0291] Example 1-1:

[0292] Exemplarily, taking the MAC CE indicating the activated spatial relationship number as an example, the MAC CE structure is defined as shown in FIG3A .

[0293] For example, if the MAC CE indicates the corresponding spatial offset, it can be based on S i (i=0,1,2,…,7) information field indication, which will not be described in detail in this disclosure.

[0294] Example 1-2:

[0295] For example, taking the spatial relationship number indicated by MAC CE as an example, the MAC CE structure is defined as shown in FIG3B .

[0296] For example, if the MAC CE indicates the corresponding spatial offset, it can be indicated based on the Spatial Relation Info ID information field, which is not described in detail in this disclosure.

[0297] Example 1-2:

[0298] The terminal determines the spatial relationship between non-SBFD and SBFD time units based on the newly introduced MAC CE. Based on the LCID number corresponding to the MAC CE, the terminal determines that the MAC CE is a MAC CE indicating the spatial relationship corresponding to SBFD.

[0299] The terminal determines the spatial relationship corresponding to the SBFD based on the activated spatial relationship number indicated by the MAC CE, eg, PUCCH-SpatialRelationInfoId, or the spatial relationship offset.

[0300] In some embodiments, for a terminal supporting SBFD, the spatial relationship corresponding to the PUCCH is determined based only on the newly introduced MAC CE, and the indication information of the legacy MAC CE is ignored;

[0301] In some embodiments, for a terminal supporting SBFD, if the indication information of the legacy MAC CE is received, the terminal updates the spatial relationship of the PUCCH corresponding to non-SBFD based on the indication information of the legacy MAC CE. For the spatial relationship corresponding to SBFD, the aforementioned activated spatial relationship is deactivated or not updated;

[0302] In some embodiments, for a terminal supporting SBFD, if indication information of a legacy MAC CE is received, the terminal updates the spatial relationship between PUCCHs corresponding to non-SBFD and SBFD based on the indication information of the legacy MAC CE.

[0303] In some embodiments, for a terminal supporting SBFD, upon receiving a newly introduced MAC CE, it is not expected to receive a legacy MAC CE indicating a PUCCH spatial relationship.

[0304] Exemplarily, the spatial relationship offset is equal to the offset between the spatial relationship number corresponding to the SBFD and the ID corresponding to the non-SBFD.

[0305] Example 1-3:

[0306] Exemplarily, taking the MAC CE indicating the activated spatial relationship number as an example, the MAC CE structure is defined as shown in Figure 3C.

[0307] For example, the terminal is based on S in Oct3 i The domain determines the spatial relationship corresponding to the non-SBFD time unit, and the terminal is based on the S in Oct4 i The domain determines the spatial relationship corresponding to the SBFD time unit;

[0308] For example, the terminal is based on S in Oct3 i The domain determines the spatial relationship corresponding to the SBFD time unit, and the terminal is based on the S i The domain determines the spatial relationship corresponding to the non-SBFD time unit;

[0309] For example, if the MAC CE indicates the corresponding spatial offset, the S value of Oct3 and / or Oct4 may be used as the basis. i (i=0,1,2,…,7) information field indication, which will not be described in detail in this disclosure.

[0310] Exemplarily, the proportion of MAC CE is fixed, for example, always 32 bits.

[0311] Example 1-4:

[0312] Exemplarily, taking the MAC CE indicating the activated spatial relationship number as an example, the MAC CE structure is defined as shown in Figure 3D.

[0313] Exemplarily, corresponding to the same PUCCH resource, the terminal determines the spatial relationship corresponding to the non-SBFD time unit based on the first row of the Spatial Relation Info field, e.g., Oct 3, and determines the spatial relationship corresponding to the SBFD time unit based on the second row of the Spatial Relation Info field, e.g., Oct 4;

[0314] Exemplarily, corresponding to the same PUCCH resource, the terminal determines the spatial relationship corresponding to the SBFD time unit based on the first row of the Spatial Relation Info field, e.g., Oct 3, and determines the spatial relationship corresponding to the non-SBFD time unit based on the second row of the Spatial Relation Info field, e.g., Oct 4;

[0315] Exemplarily, if the MAC CE indicates a corresponding spatial offset corresponding to the same PUCCH resource, the spatial offset corresponding to the SBFD may be indicated based on the first row of the Spatial Relation Info field and / or the second row of the Spatial Relation Info field, which will not be elaborated in this disclosure.

[0316] Example 2:

[0317] Considering that the traditional MAC CE can indicate the activation status of multiple spatial relationships in the spatial relationship list, the embodiments of the present disclosure mainly consider indicating the spatial relationship corresponding to the SBFD time unit based on the traditional MAC CE.

[0318] Illustratively, the traditional MAC CE may be a PUCCH spatial relation Activation / Deactivation MAC CE (corresponding to an LCID number equal to 49), or an enhanced PUCCH Spatial Relation Activation / Deactivation MAC CE (corresponding to an eLCID index equal to 313).

[0319] Example 2-1:

[0320] The network device indicates two activated spatial relationships based on the traditional MAC CE, which correspond to the spatial relationships corresponding to the SBFD time unit and the non-SBFD time unit respectively.

[0321] Considering the traditional mechanism, legacy terminals can only activate one spatial relationship at a time based on the traditional MAC CE corresponding to the same PUCCH resource. However, for users supporting SBFD, two spatial relationships are required. To distinguish between the two MAC CE indication methods and avoid impacting legacy terminals, for example, the implementation method may include one of the following:

[0322] Based on network device differentiation, the network device determines whether to activate one or two spatial relationships based on traditional MAC CEs based on whether the user corresponding to the MAC CE supports SBFD.

[0323] Based on the distinction of indication signaling, for example, based on the R field indication of the traditional MAC CE, R can be the R field corresponding to Oct1, or other R fields, and the present disclosure does not limit this.

[0324] If the R indicator is 0, the terminal determines that only one of the spatial relationships corresponding to the MAC CE is activated and / or the activated spatial relationship only corresponds to one time unit type.

[0325] For a terminal supporting SBFD, determine the type of time unit corresponding to the spatial relationship based on signaling indication or a predefined method. The methods include, but are not limited to:

[0326] Apply the spatial relationship to the PUCCH corresponding to non - SBFD;

[0327] Apply the spatial relationship to the PUCCH corresponding to SBFD;

[0328] Apply the spatial relationship to both SBFD and non - SBFD simultaneously;

[0329] Apply the spatial relationship to the time unit where the PUCCH resource is located. For example, if the PUCCH resource is transmitted in the SBFD time unit, the terminal determines that the spatial relationship applies to SBFD, and vice versa;

[0330] If the R indication is 1, the terminal determines that the corresponding MAC CE can activate two spatial relationships and / or the activated spatial relationship can correspond to two types of time units.

[0331] The terminal determines the two activated spatial relationships based on the following method.

[0332] Example 2 - 1:

[0333] If the traditional MAC CE is the PUCCH spatial relation Activation / Deactivation MAC CE, if S m = 1 and S n = 1, the terminal determines that the (m + 1)th and (n + 1)th spatial relationships in the corresponding spatial relationship list are activated. The spatial relationship list can be an existing spatial relationship list or a SBFD specific spatial relationship list, which is not elaborated in this disclosure.

[0334] A possible implementation method. If m < n, the terminal determines that the activated spatial relationship of S m is the spatial relationship corresponding to non - SBFD. If m > n, the terminal determines that the activated spatial relationship of S m is the spatial relationship corresponding to SBFD;

[0335] A possible implementation method. If m < n, the terminal determines that the activated spatial relationship of S m is the spatial relationship corresponding to SBFD. If m > n, the terminal determines that the activated spatial relationship of S m is the spatial relationship corresponding to non - SBFD;

[0336] A possible implementation method. If m =,n, the terminal determines that Sm The activated spatial relationship is the spatial relationship corresponding to SBFD, or the terminal determines S m The activated spatial relationship is the spatial relationship corresponding to non-SBFD, or the terminal determines that the spatial relationship activated by Si is the spatial relationship corresponding to non-SBFD and SBFD, and the spatial relationships are the same.

[0337] Example 2-2:

[0338] If the traditional MAC CE is the enhanced PUCCH spatial relation Activation / Deactivation MAC CE, if the terminal determines two activated spatialRelationInfo ID numbers based on the same PUCCH resource ID, the terminal determines that two spaces are activated, and they correspond to the SBFD time unit and the non-SBFD time unit respectively.

[0339] Taking the MAC CE shown in Figure 3B as an example, if the terminal is based on Oct 2 and other Octs, e.g., Oct 4, the PUCCH resource ID corresponding to the same terminal determines that the PUCCH resources associated with the two Octs correspond to two activated spatial relationships, and the spatial relationship is determined based on the spatialRelationInfo ID associated with the PUCCH resource.

[0340] For example, for the same PUCCH resource, the terminal determines the correspondence between the activated spatial relationship and SBFD and non-SBFD based on the size of the Oct num where the activated spatialRelationInfo ID is located. The correspondence is similar to that in Example 1-1 and will not be repeated here.

[0341] Example 2-3:

[0342] For UE corresponding to SBFD, a second spatial relationship list is additionally configured on the basis of the existing spatial relationship list, and the second spatial relationship list is applied to SBFD.

[0343] A UE supporting SBFD receives traditional MAC CE activation signaling, which is applied to both the existing spatial relationship list and the second spatial relationship list. Based on the two lists, the UE determines the spatial relationships corresponding to SBFD and non-SBFD, respectively.

[0344] If the legacy MAC CE is a PUCCH spatial relation Activation / Deactivation MAC CE, and if Si=1, the terminal supporting SBFD determines that both the existing spatial relation list and the (i+1)th spatial relation in the second spatial relation list are activated.

[0345] If the legacy MAC CE is the enhanced PUCCH spatial relation Activation / Deactivation MAC CE, if spatialRelationInfo1 of a specific PUCCH resource is activated, the terminal supporting SBFD determines that both spatialRelationInfo1 in the existing spatial relation list and the second spatial relation list are activated.

[0346] The disclosed embodiment designs a corresponding MAC CE indication method based on the configuration spatial relationship list. Based on the above indication method, the terminal determines the corresponding spatial relationship of SBFD and non-SBFD respectively, and transmits the corresponding PUCCH.

[0347] Implementation 2:

[0348] In a possible implementation, after the terminal determines the spatial list on the non-SBFD time unit based on a traditional mechanism, the terminal determines the spatial relationship corresponding to the SBFD time unit based on a predefined method.

[0349] Exemplarily, the terminal determines a mapping relationship between the SBFD spatial relationship and the non-SBFD spatial relationship based on pre-definition or terminal implementation.

[0350] Exemplarily, the mapping relationship may be determined based on a reference signal having a QCL relationship corresponding to the spatial relationship, and the reference signal may be one or more of SSB, CSI-RS, and SRS.

[0351] Taking SSB as an example, if the terminal determines that the reference SSB associated with non-SBFD is SSB#1 based on the traditional mechanism, and the terminal determines that SSB#2 of SBFD is associated with SSB#1 of non-SBFD based on predefinition or implementation, the terminal determines that the reference SSB associated with SBFD is SSB#2.

[0352] CSI-RS and SRS are similar to SSB and will not be described in detail here.

[0353] The present disclosure is mainly based on the premise that the terminal determines the spatial relationship mapping relationship between SBFD and non-SBFD based on predefinition or terminal implementation. On the basis of determining the non-SBFD correspondence relationship based on the traditional mechanism, the terminal determines the SBFD correspondence based on the above mapping relationship.

[0354] Implementation 3:

[0355] In a possible implementation manner, the terminal determines a spatial relationship offset between SBFD and non-SBFD, and determines a spatial relationship corresponding to the PUCCH in the SBFD time unit.

[0356] Exemplarily, the spatial relationship offset may be equal to the Id offset of the PUCCH-SpatialRelationInfoId corresponding to SBFD compared to the Id offset of the non-SBFD.
