[0032] The method for indicating carrier channel status information provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0033] like Figure 2 As shown, an embodiment of the present invention provides a method 200 for indicating carrier channel state information, which can be performed by a first terminal device. In other words, the method can be performed by software or hardware installed in the first terminal device. The method includes the following steps:

[0034] S202: The first terminal generates a first MAC CE.

[0035] The first MAC CE includes channel state information corresponding to one or more carrier components of the side link.

[0036] The first terminal may generate a first MAC CE, where the first MAC CE includes channel state information corresponding to multiple carrier components of the side link.

[0037] The first terminal may generate multiple first MAC CEs, each of which may include channel state information corresponding to multiple carrier components of a side link, and the channel state information corresponding to multiple carrier components is sent by sending the multiple first MAC CEs.

[0038] S204: Send the first MAC CE to the second terminal.

[0039] An embodiment of the present invention provides a method for indicating carrier channel status information, by generating a first MAC CE, wherein the first MAC CE includes channel status information corresponding to one or more carrier components of a side link; and sending the first MAC CE to a second terminal, thereby solving the problem that the MAC CE transmitted by the SL cannot represent the CSI corresponding to multiple CCs.

[0040] like Figure 3a As shown, an embodiment of the present invention provides a method 300 for indicating carrier channel state information, which can be performed by a first terminal device. In other words, the method can be performed by software or hardware installed in the first terminal device. The method includes the following steps:

[0041] S302: The first terminal generates a first MAC CE, wherein the first MAC CE includes channel state information corresponding to one or more carrier components of the side link, and the channel state information corresponding to the multiple carrier components of the side link is indicated by a carrier component bitmap corresponding to the first MAC CE.

[0042] This step can be done using Figure 2 The description of step S202 of the embodiment will not be repeated here for the repeated parts.

[0043] Figure 3b A schematic diagram of the first MAC CE is shown. Figure 3b As shown, in one implementation, the first MAC CE includes: a channel quality indicator (CQI) field and a carrier component bitmap corresponding to the first MAC CE.

[0044] In one implementation, the first bit in the carrier component bitmap corresponding to the first MAC CE is used to indicate whether the corresponding first carrier component has corresponding channel state information, wherein the channel state information includes at least one of CQI and RI.

[0045] For example, C0=1 indicates that the corresponding SLCC 1 has corresponding channel state information (eg, CQI value), and C1=0 indicates that the SLCC 2 has no corresponding channel state information.

[0046] In one implementation, the first MAC CE includes multiple CQI fields, and there is a one-to-one correspondence between the CQI field and the target bit indicating that the first carrier component has corresponding channel state information. The CQI field corresponding to the target bit is indicated by the order of the target bit in the carrier component bitmap.

[0047] like Figure 3b As shown, for example, C0=1 indicates that the corresponding SLCC 1 has a corresponding CQI value, and C1=1 indicates that the corresponding SLCC 2 has a corresponding CQI value, and C0 and C1 are target bits.

[0048] C2=0 indicates that the corresponding SL CC 3 has no corresponding CQI value, and C2 is not a target bit.

[0049] C3=1 indicates that the corresponding SL CC 4 has a corresponding CQI value, and C3 is the target bit.

[0050] It can be seen that the target bits are sorted in the carrier component bitmap as follows: C0, C1, C3. Through this sorting, it can be determined that: the CQI value corresponding to the first octet Oct1 in the figure corresponds to the target bit C0, which is the CQI value of SL CC 1 corresponding to C0; the CQI value corresponding to the second octet Oct2 in the figure corresponds to the target bit C1, which is the CQI value of SL CC 2 corresponding to C1; the CQI value corresponding to the third octet Oct3 (not shown in the figure) corresponds to the target bit C3, which is the CQI value of SL CC 4 corresponding to C3.

[0051] Similarly, in one implementation, the first MAC CE also includes multiple rank indicators (RI), and the RI field has a one-to-one correspondence with a target bit indicating that the first carrier component has corresponding channel state information, and the RI field corresponding to the target bit is indicated by the order of the target bit in the carrier component bitmap.

[0052] As an optional implementation, for one or more CCs with channel state information indicated in the bitmap, the channel state information corresponding to each of the one or more CCs can be arranged in ascending order based on the CC identifier. Of course, it can also be arranged in descending order, which is not specifically limited in this embodiment.

[0053] As an optional implementation, for one or more CCs indicating channel state information in the bitmap, each of the one or more CCs corresponds to an octet, and an octet corresponding to each CC includes channel state information corresponding to the CC (e.g., CQI and / or RI).

[0054] Optionally, the first MAC CE may further include a reserved bit R. As another optional implementation, for CCs in the bitmap indicating channel state information, each CC corresponds to an octet, and an octet corresponding to each CC includes a reserved bit R. The number of reserved bits is not limited. For example, Figure 3b The first octet in the byte includes 3 reserved bits R, and the second octet also includes 3 reserved bits.

[0055] It should be noted that Figure 3b The MAC CE in the protocol is designed to send channel state information of up to 32 CCs. i The field has four octets. Of course, if the channel state information of up to 8 CCs can be sent, C i The domain may also have one octet, which is not specifically limited in this embodiment. Figure 3b The channel state information of the MAC CE in the one or more octets is arranged in C i Of course, one or more octets containing the channel state information may also be placed in front of the C i This embodiment does not make any specific limitation after the domain.

[0056] S304: Send the first MAC CE to the second terminal.

[0057] An embodiment of the present invention provides a method for indicating carrier channel status information, by generating a first MAC CE, wherein the first MAC CE includes channel status information corresponding to one or more carrier components of a side link; and sending the first MAC CE to a second terminal, thereby solving the problem that the MAC CE transmitted by the SL cannot represent the CSI corresponding to multiple CCs.

[0058] like Figure 4aAs shown, an embodiment of the present invention provides a method 400 for indicating carrier channel state information, which can be performed by a first terminal device. In other words, the method can be performed by software or hardware installed in the first terminal device. The method includes the following steps:

[0059] S402: The first terminal generates a first MAC CE, wherein the first MAC CE includes channel state information corresponding to one or more carrier components of the side link, and the channel state information corresponding to the multiple carrier components of the side link is indicated by a carrier component index corresponding to the first MAC CE.

[0060] This step can be done using Figure 2 The description of step S202 of the embodiment will not be repeated here for the repeated parts.

[0061] Figure 4b-4e A schematic diagram of a first MAC CE is shown. In one implementation, the first MAC CE includes a first field and a second field, wherein the first field is used to indicate an index of a corresponding second carrier component (e.g., CC index), and the second field is used to indicate channel state information corresponding to the index; wherein the channel state information includes at least one of CQI and RI.

[0062] In an optional implementation manner, the first field and the second field corresponding to each CC use one octet, for example, Figure 4b In the , the first field and the second field of the CC corresponding to the CC index use one octet Oct1.

[0063] In another optional implementation manner, the first domain and the second domain corresponding to each CC are distributed in two octets. Optionally, the first MAC CE may also include a reserved bit R. Figure 4c , 4d Different numbers of reserved bits R are shown respectively.

[0064] As an optional implementation, the channel state information is based on CC index i The arrangement is performed in ascending order. Of course, the arrangement can also be performed in descending order, which is not specifically limited in this embodiment.

[0065] In another implementation, optionally, the first field may occupy a reserved bit position R of an existing CSI MAC CE. Figure 4e As shown, for example, the reserved bit position R is 3 bits, and the first domain occupies the reserved bit position R to indicate 8 CC indexes, and the corresponding relationship may include:

[0066] 000->CC1

[0067] 001->CC2

[0068] 010->CC3

[0069] 011->CC4

[0070] 100->CC5

[0071] 101->CC6

[0072] 110->CC7

[0073] 111->CC8

[0074] In one implementation, the correspondence between the carrier frequency and the carrier component index indicated by the first domain is pre-configured or configured by the base station or configured by the second terminal. In one implementation, the correspondence is transmitted via a system message or an RRC reconfiguration message or a sidelink RRC reconfiguration message.

[0075] Optionally, the base station configures CC index values, including which carrier frequencies CC1, CC2, ..., CC8 correspond to, for example, including f1, f2, ..., f8. At this time, the corresponding relationship can be transmitted through a system message or an RRC reconfiguration message or a sidelink RRC reconfiguration message.

[0076] Optionally, pre-configured CC index values ​​include which carrier frequencies CC1, CC2, ..., CC8 correspond to, for example, f1, f2, ..., f8. In this case, there is no need for the network to negotiate with the SL UE.

[0077] Optionally, Sidelink RRC configures CC index values, including which carrier frequency CC1, CC2, ..., CC8 corresponds to, for example, including f1, f2, ..., f8. At this time, the SL UE receives the corresponding information sent by the opposite SL UE 2 through the Sidelink RRC reconfiguration message. The corresponding information sent by the opposite SL UE 2 can be determined by itself or can be configured from its serving base station.

[0078] S404: Send the first MAC CE to the second terminal.

[0079] An embodiment of the present invention provides a method for indicating carrier channel status information, by generating a first MAC CE, wherein the first MAC CE includes channel status information corresponding to one or more carrier components of a side link; and sending the first MAC CE to a second terminal, thereby solving the problem that the MAC CE transmitted by the SL cannot represent the CSI corresponding to multiple CCs.

[0080] like Figure 5As shown, an embodiment of the present invention provides a method 500 for indicating carrier channel state information, which can be performed by a first terminal device. In other words, the method can be performed by software or hardware installed in the first terminal device. The method includes the following steps:

[0081] S502: The first terminal generates a first MAC CE, where the first MAC CE includes channel state information corresponding to one or more carrier components of the side link.

[0082] This step can be done using Figure 2 The description of step S202 of the embodiment will not be repeated here for the repeated parts.

[0083] Figure 6a-6b A schematic diagram of a first MAC CE is shown. In one implementation, the first MAC CE may include: a third field and a fourth field, wherein a first bit in the third field is used to indicate a rank indication RI of a sidelink channel state information CSI report, at least one second bit in the third field is used to indicate a carrier component index, and the fourth field is used to indicate a CQI corresponding to the index.

[0084] like Figure 6a As shown, in one implementation, the third field is the RI' field, and the RI' field is obtained by extending the RI field to 6 bits, wherein a first bit in the RI' field, for example, the last bit, is used to indicate the rank indication RI of the sidelink channel state information CSI report, that is, the meaning of the RI field, and the remaining 5 bits are used as the second bit to indicate the carrier component index CCindex. Optionally, the first MAC CE may also include a reserved bit R. For example, a 2-bit reserved bit R.

[0085] like Figure 6b As shown, in one implementation, the third field is the RI' field, and the RI' field is obtained by extending the RI field to 7 bits, wherein a first bit in the RI' field, for example, the last bit, is used to indicate the rank indication RI of the sidelink channel state information CSI report, and the remaining 6 bits are used as the second bit to indicate the carrier component index CC index. Optionally, the first MAC CE may also include a reserved bit R. For example, a 1-bit reserved bit R.

[0086] S504: Send the first MAC CE to the second terminal.

[0087] An embodiment of the present invention provides a method for indicating carrier channel status information, by generating a first MAC CE, wherein the first MAC CE includes channel status information corresponding to one or more carrier components of a side link; and sending the first MAC CE to a second terminal, thereby solving the problem that the MAC CE transmitted by the SL cannot represent the CSI corresponding to multiple CCs.

[0088] like Figure 7 As shown, an embodiment of the present invention provides a method 700 for indicating carrier channel state information, which can be performed by a first terminal device. In other words, the method can be performed by software or hardware installed in the first terminal device. The method includes the following steps:

[0089] S702: The first terminal generates a first MAC CE. When the first MAC CE includes channel state information corresponding to a carrier component of a side link, there is a correspondence between the channel state information included in the first MAC CE and the carrier frequency at which the second terminal receives the first MAC CE.

[0090] This step can be done using Figure 2 The description of step S202 of the embodiment will not be repeated here for the repeated parts.

[0091] S704: Send the first MAC CE to the second terminal.

[0092] Therefore, after receiving the first MAC CE, the second terminal can determine the channel state information included in the first MAC CE according to the carrier frequency at which the first MAC CE is received.

[0093] An embodiment of the present invention provides a method for indicating carrier channel status information, by generating a first MAC CE, wherein the first MAC CE includes channel status information corresponding to one or more carrier components of a side link; and sending the first MAC CE to a second terminal, thereby solving the problem that the MAC CE transmitted by the SL cannot represent the CSI corresponding to multiple CCs.

Figure 8 A method for indicating carrier channel state information according to another embodiment of the present invention is described in detail. It can be understood that the interaction between the second terminal device and the first terminal device described from the second terminal device side is similar to Figure 2-7 The description on the first terminal device side in the method shown is the same or corresponding. To avoid repetition, the relevant description is appropriately omitted.

[0096] S802: Receive a first MAC CE sent by a first terminal, where the first MAC CE includes channel state information corresponding to one or more carrier components of a side link.

[0101] It should be noted that the method for indicating carrier channel status information provided in the embodiment of the present application can be performed by a device for indicating carrier channel status information, or a control module in the device for executing the method of loading the above method. In the embodiment of the present application, the method for indicating carrier channel status information provided in the embodiment of the present application is described by taking the method for loading the carrier channel status information performed by a device for indicating carrier channel status information as an example.

[0103] The generating module 910 is used to generate a first MAC CE, wherein the first MAC CE includes channel state information corresponding to one or more carrier components of the side link. The sending module 920 is used to send the first MAC CE to the second terminal.

[0104] In one implementation, the channel state information corresponding to the multiple carrier components of the side link is indicated by a carrier component bitmap corresponding to the first MAC CE.

[0105] In one implementation, the first bit in the carrier component bitmap corresponding to the first MAC CE is used to indicate whether the corresponding first carrier component has corresponding channel state information, wherein the channel state information includes at least one of a channel quality indication CQI and a rank indication RI.
