[0031] The information transmission method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0032] like Figure 2 As shown, an embodiment of the present application provides an information transmission method, including:

[0033] Step 201: Based on terminal implementation or first information, the first communication device determines whether to send a first media access layer control unit MAC CE, the first MAC CE is a discontinuous reception MAC CE in the secondary link SL, and the first information is information used to determine whether to send the first media access layer control unit MAC CE.

[0034] In the embodiment of the present application, the first communication device is specifically a first terminal. The discontinuous reception (DRX) MAC CE is used to indicate to stop running related DRX timers (such as DRX-onDurationTimer, DRX-InactivityTimer), so that the terminal enters a DRX inactive state.

[0035] In an embodiment of the present application, based on the terminal implementation or the first information, it is determined whether to send the first media access layer control unit MAC CE, and the first MAC CE is a discontinuous reception MAC CE in the secondary link SL. In this way, the sending mechanism of the first MAC CE is clarified, so that the terminal can send the first MAC CE according to the sending mechanism.

[0036] Optionally, the first information includes at least one of the following:

[0037] Item 1: indication information sent by the second communication device, where the indication information is used to indicate whether to send the first MAC CE or not to send the first MAC CE;

[0038] Item 2: terminal auxiliary information sent by the second communication device;

[0039] The third item: priority information of the first MAC CE.

[0040] In the embodiment of the present application, the second communication device is a second terminal or a network side device, which can be a service base station of the first terminal or a service base station of the second terminal. Optionally, the service base station of the first terminal and the service base station of the second terminal can be the same or different.

[0041] For the first item above, the indication information may be an explicit instruction, such as a 1-bit indication, and the first terminal directly decides whether to send the first MAC CE or not to send the first MAC CE through the indication information. Specifically, when the indication information indicates to send the first MAC CE, the first communication device sends the first MAC CE, and when the indication information indicates not to send the first MAC CE, the first communication device does not send the first MAC CE.

[0042] For the second item above, the terminal auxiliary information may specifically be terminal auxiliary information of the second terminal, and the first terminal determines whether to send the first MAC CE according to the terminal auxiliary information.

[0043] Further optionally, the terminal auxiliary information includes at least one of the following:

[0044] Uu discontinuous reception configuration information;

[0045] Business service quality QoS information;

[0046] Destination L2 ID.

[0047] Here, the first terminal determines different requirements that need to be met based on the terminal auxiliary information, and then determines whether to send the first MAC CE.

[0048] For the third item above, optionally, the priority information of the first MAC CE is a fixed priority value;

[0049] Alternatively, the priority information of the first MAC CE is determined according to a priority value of at least one SL logical channel;

[0050] Alternatively, the priority information of the first MAC CE is determined according to the SL media access control protocol data unit MAC PDU multiplexing priority.

[0051] In the case where the priority information of the first MAC CE is a fixed priority value, one may be selected from the priority value range [1,8] allowed by the protocol as the priority of the first MAC CE, for example, priority value=8.

[0052] In the case where the priority information of the above-mentioned first MAC CE is determined according to the priority value of at least one SL logical channel, the priority information of the first MAC CE can be determined according to the priority of the logical channel with the highest priority in the SL logical channels to be transmitted, or, the priority information of the first MAC CE can be determined according to the highest priority value in the configured SL logical channels.

[0053] In the case where the priority information of the first MAC CE is determined according to the SL media access control protocol data unit MAC PDU multiplexing priority, the SL MAC PDU multiplexing priority may be at least one of the following:

[0054] Shared control channel data > first MAC CE > SL CSI report MAC CE > traffic channel data;

[0055] Shared control channel data > SL CSI report MAC CE > first MAC CE > traffic channel data;

[0056] Data of shared control channel>SL CSI report MAC CE>data of traffic channel>first MAC CE.

[0057] Optionally, in an embodiment of the present application, when the first information is priority information of the first MAC CE, and the priority information of the first MAC CE is determined according to a SL MAC PDU multiplexing priority order, the method further includes:

[0058] In the case where uplink transmission and SL transmission meet preset conditions, if the SL transmission only includes the first MACCE, uplink transmission is prioritized.

[0059] Here, it can be understood that the priority of the first MAC CE is always lower than that of the SL service channel data.

[0060] The above preset condition may be that uplink transmission and SL transmission cannot be performed at the same time, or that one of the uplink transmission and the SL transmission needs to be selected for transmission due to power limitation.

[0061] Specifically, when the above transmission and SL transmission meet the preset conditions, if the SL transmission only includes the first MAC CE, uplink transmission is prioritized and the SL transmission is abandoned.

[0062] In addition, when the priority information of the first MAC CE is determined according to a fixed priority value (the smaller the priority value, the higher the priority it reflects), or is determined according to the priority value of at least one SL logical channel, if the uplink transmission and the SL transmission meet the preset conditions, and the SL transmission contains the first MAC CE, the existing rules are reused. That is, the network is configured with two thresholds, namely the SL priority threshold and the UL priority threshold. If the highest priority value in the SL transmission is less than the SL priority threshold, and the highest priority value in the UL transmission is greater than or equal to the UL priority threshold, SL is prioritized; otherwise, UL is prioritized.

[0063] If the priority information of the first MAC CE is determined according to the SL MAC PDU multiplexing priority, if the priority of the first MAC CE is always lower than the SL service channel data, and the SL transmission includes the first MAC CE and the second information, the above existing rules are reused, and at this time, it is only necessary to consider whether the second information satisfies the judgment condition "the highest priority value in the SL transmission is less than the SL priority threshold". The second information includes at least one of the SL CSI report MAC CE and the SL service channel data.

[0064] If the priority information of the first MAC CE is determined according to the SL MAC PDU multiplexing priority, if the priority of the first MAC CE is always higher than the SL service channel data, and the SL transmission only contains the first MAC CE, UL is always prioritized.

[0065] If the priority information of the first MAC CE is determined according to the SL MAC PDU multiplexing priority, if the priority of the first MAC CE is always higher than the SL service channel data, and the SL transmission includes the first MAC CE and the above-mentioned second information, the existing rules are reused, and at this time, the judgment condition "the highest priority value in SL transmission is less than the SL priority threshold" is met, so it is only necessary to see whether the comparison result of UL transmission meets the judgment condition "the highest priority value in UL transmission is greater than or equal to the UL priority threshold" to further decide whether to prioritize UL or SL.

[0066] Optionally, the method of the embodiment of the present application further includes:

[0067] The first communication device determines a hybrid automatic repeat request HARQ attribute of the first MAC CE according to at least one of the following;

[0068] Preset fixed attributes;

[0069] HARQ attributes of at least one SL logical channel.

[0070] For example, the first communications device selects one from the HARQ attribute value enumeration type [enabled, disabled] allowed by the protocol as the HARQ attribute of the first MAC CE. For example, the HARQ attribute of the first MAC CE is fixed to disabled.

[0071] For another example, the first communication device determines according to the HARQ attribute of the logical channel with the highest priority value in the SL logical channels to be transmitted data, or determines according to the HARQ attribute of the logical channel with the highest priority value in the configured SL logical channels.

[0072] For another example, when the first MAC CE is sent alone, the HARQ attribute of the first MAC CE is determined according to a preset fixed attribute, and when the first MAC CE is sent together with SL data, the HARQ attribute of the first MAC CE is determined according to the HARQ attribute of at least one SL logical channel. In this way, if the HARQ attribute of the logical channel with the highest priority value in the SL logical channels with data to be transmitted is disabled, and the HARQ attribute of the first MAC CE is fixed to enabled, the HARQ attribute of the first MAC CE can be temporarily changed, so that it can be multiplexed and transmitted together according to the data to be transmitted.

[0073] Optionally, the method in the embodiment of the present application, after determining the hybrid automatic repeat request HARQ attribute of the first MAC CE, further includes:

[0074] The first communication device determines, according to a preset rule, a HARQ attribute of a SL transmission, where the SL transmission includes at least a first MAC CE;

[0075] The preset rules include at least one of the following:

[0076] In a case where the HARQ attribute of the first MAC CE is a preset fixed attribute, determining the HARQ attribute of the SL transmission according to the preset fixed attribute of the first MAC CE;

[0077] In a case where the HARQ attribute of the first MAC CE is the HARQ attribute of at least one SL logical channel, if the SL transmission includes first data, determining the HARQ attribute of the SL transmission according to the HARQ attribute of the logical channel with the highest priority value in the SL logical channels corresponding to the first data;

[0078] In a case where the HARQ attribute of the first MAC CE is the HARQ attribute of at least one SL logical channel, if the SL transmission does not include the first data, determining the HARQ attribute of the SL transmission according to the HARQ attribute of the logical channel with the highest priority value in the configured SL logical channels;

[0079] In the case where the HARQ attribute of the first MAC CE is determined based on a preset fixed attribute and the HARQ attribute of at least one SL logical channel, if the SL transmission contains first data, the HARQ attribute of the SL transmission is determined based on the HARQ attribute of the logical channel with the highest priority value in the SL logical channel corresponding to the first data.

[0080] In the case where the HARQ attribute of the first MAC CE is determined based on a preset fixed attribute and the HARQ attribute of at least one SL logical channel, if the SL transmission does not contain the first data, the HARQ attribute of the SL transmission is determined based on the preset fixed attribute of the first MAC CE.

[0081] Optionally, the first data is a MAC service data unit SDU.

[0082] In an embodiment of the present application, based on the terminal implementation or the first information, it is determined whether to send the first media access layer control unit MAC CE, and the first MAC CE is a discontinuous reception MAC CE in the secondary link SL. In this way, the sending mechanism of the first MAC CE is clarified, so that the terminal can send the first MAC CE according to the sending mechanism.

[0083] like Figure 3 As shown, the embodiment of the present application also provides an information transmission method, including:

[0084] Step 301: The second communication device sends first information, where the first information is information used to determine whether the first communication device sends a first media access layer control element MAC CE.

[0085] In this step, the first communication device is specifically a first terminal. The second communication device is a second terminal or a network side device, and the network side device can be a service base station of the first terminal or a service base station of the second terminal. Optionally, the service base station of the first terminal and the service base station of the second terminal can be the same or different.

[0086] The above-mentioned discontinuous reception (DRX) MAC CE is used to instruct to stop running related DRX timers (such as DRX-onDurationTimer, DRX-InactivityTimer), so that the terminal enters the DRX inactive state.

[0087] In an embodiment of the present application, first information is sent, where the first information is information used to determine whether the first communication device sends a first media access layer control unit MAC CE, so that the first communication device can determine whether to send the first MAC CE based on the first information.

[0088] Optionally, the first information includes at least one of the following:

[0095] The above indication information and terminal auxiliary information have been described in detail in the method embodiment on the first communication device side, and will not be repeated here.
