[0164] Figure 1 The block diagram of a wireless communication system to which the embodiments of this application can be applied is shown. The wireless communication system includes a terminal device 11 and a network side device (or network device) 12. Among them, the terminal device 11 can also be called a terminal or a user terminal (User Equipment, UE). It should be noted that the specific type of the terminal 11 is not limited in the embodiments of this application. The network side device 12 can be a base station or a core network. It should be noted that only the base station in the NR system is taken as an example in the embodiments of this application, but the specific type of the base station is not limited.

[0165] To enable those skilled in the art to better understand the embodiments of this application, the following description is provided first.

[0166] The Synchronization Signal / PBCH (SSB) is one of the most important pilot channels used in 5G, and its role is related to many aspects of UE access to the cell, such as cell search, beam measurement, beam selection, beam recovery, etc.

[0167] An SSB Burst Set refers to a set of multiple SSBs within a certain period. In high frequencies, multiple SSBs within an SSB Burst Set can be used for beam scanning to enhance cell coverage. Currently, there are 6 types of periods for SSB Burst Sets: 5ms, 10ms, 20ms, 40ms, 80ms, and 160ms, and this period will be indicated in SIB1. In the existing NR system, the protocol stipulates that the default SSB transmission period for the UE is 20ms. Therefore, for a cell that supports initial cell search, its actual SSB transmission period can be 5ms, 10ms, and 20ms, but not longer than 20ms.

[0168] As Figure 2 shown, an embodiment of this application provides an information transmission method, which is executed by a terminal. The method includes:

[0169] Step 201: When a preset condition is met, send first information, where the first information is used to assist a network-side device in sending a Synchronization Signal Block (SSB); this first information can also be described as auxiliary information;

[0170] Optionally, the first information is used to indicate that the network side sends an SSB on demand. Optionally, the first information can further indicate the SSB configuration requested by the terminal to be sent or the SSB configuration expected by the terminal.

[0171] Optionally, in an embodiment of this application, after the terminal sends the first information, it further includes: receiving the SSB configuration sent by the network-side device, where the SSB configuration is the SSB configuration requested by the terminal to be sent or the SSB configuration expected by the terminal.

[0172] Among them, the preset condition includes at least one of the following:

[0173] The first item: The energy-saving mode of the serving cell changes;

[0174] For example, the terminal operates in the CA mode and configures a deactivated Secondary Cell (Scell) 1. For the purpose of energy saving, Scell 1 broadcasts the SSB in a more energy-saving manner (such as broadcasting sparse SSBs with an SSB period of 160ms). Subsequently, as the network load increases, Scell 1 exits the energy-saving mode and notifies the UE. After the UE discovers that Scell 1 has exited the energy-saving mode, it sends auxiliary information to the network side.

[0175] Optionally, when the SSB of Scell 1 meets a certain condition, such as when the SSB period is greater than or less than a certain threshold, and the power saving mode of Scell 1 changes, the UE sends a first piece of information to the network side; for example, when the SSB pattern is a certain specific pattern, and the power saving mode of Scell 1 changes, UE1 sends auxiliary information to the network side.

[0176] The second item: the SSB pattern of the serving cell changes;

[0177] For example, the terminal operates in the CA mode and is configured with a deactivated secondary cell (Scell) 1. For the purpose of energy saving, Scell 1 broadcasts the SSB in a more energy-saving manner (such as broadcasting sparse SSBs). As the traffic increases, Scell 1 changes the SSB pattern (such as becoming a denser SSB to provide more efficient services for UE1) and notifies the UE.

[0178] When UE1 determines that the SSB pattern of the serving cell has changed, the UE sends auxiliary information to the network side.

[0179] The third item: the signal quality of the serving cell is less than or equal to the signal quality threshold;

[0180] For example, the terminal operates in the CA mode and is configured with a primary cell (Pcell) and a secondary cell Scell 1. For the purpose of energy saving, Scell 1 broadcasts the SSB in a more energy-saving manner (such as a relatively long SSB period). When the signal quality of the serving cell (which can be the primary cell or the secondary cell) measured by the UE is less than or equal to the signal quality threshold, it may mean that the UE needs more SSBs under Scell 1. Therefore, the UE sends auxiliary information to the network side.

[0181] Optionally, here the signal quality of the serving cell also needs to be greater than a certain threshold, which means the UE is under the coverage of this serving cell (such as Scell1).

[0182] The fourth item: the SSB period of the serving cell changes.

[0183] For example, the terminal operates in the CA mode and is configured with a primary cell (Pcell) and a secondary cell Scell 1. For the purpose of energy saving, Scell 1 broadcasts the SSB in a more energy-saving manner (such as a relatively long SSB period, with an SSB period of 320 ms). When the UE receives indication information indicating that the SSB period of the serving cell becomes shorter (such as becoming 80 ms), the UE sends auxiliary information to the network side.

[0184] Optionally, the network side may pre-configure Scell 1 as a special cell (e.g., a cell that sends SSBs on demand) for UE1. When the SSB period of Scell 1 becomes longer or shorter, the UE sends the first information to the network side.

[0185] Fifth item: The first information changes;

[0186] For example, at time T1, the UE sends auxiliary information 1 to the network side, which optionally includes the desired SSB configuration 1 or the serving cell L3 measurement result; at time T2, the desired SSB configuration of the UE changes, and the UE sends auxiliary information 2 to the network side, which optionally contains the desired SSB configuration 2. Optionally, when the difference between T2 and T1 is greater than a certain threshold, UE1 is allowed to send the auxiliary information to the network side.

[0187] Sixth item: Receive a first request sent by the network side device, where the first request is used to request the sending of the first information.

[0188] In the embodiments of the present application, the network side may, based on its own algorithm, determine that the UE needs to send the first information to assist in configuring the SSB. For example, for the purpose of energy saving, a certain cell sends sparse SSBs. To better serve the UE, the network side sends a first request to the terminal. After receiving the first request, the terminal sends the auxiliary information.

[0189] Seventh item: The serving cell is a cell that sends SSBs on demand;

[0190] Optionally, the terminal determines whether the serving cell is a cell that sends SSBs on demand according to the indication of the network side.

[0191] Eighth item: The SSB period of the serving cell is greater than or less than the SSB period threshold;

[0192] Optionally, the SSB period threshold is agreed upon by the protocol or indicated by the network side.

[0193] Ninth item: The SSB mode of the serving cell is a specific SSB mode;

[0194] Optionally, the specific SSB mode may be indicated by the network side or agreed upon by the protocol.

[0195] Tenth item: The measurement of the serving cell does not meet the measurement requirements;

[0196] For example, the measurement requirement for the UE to perform the serving cell measurement is that the measurement period is n * DRX periods. However, according to the current SSB sending period of the serving cell, the UE cannot obtain the result corresponding to the serving cell within n * DRX periods. Therefore, the UE sends the auxiliary information to the network side.

[0197] For another example, the network side configures cell A as a secondary cell of the UE (which can be an active or deactivated secondary cell). The UE determines that the current SSB configuration cannot meet the measurement requirements for measuring secondary cell 1 according to the current SSB configuration; or, as the UE moves, the signal quality of the UE under secondary cell 1 becomes worse and worse, and more SSBs need to be measured to obtain the measurement result under secondary cell 1. However, according to the SSB period under secondary cell 1, the UE cannot obtain the measurement result under secondary cell 1 in time, thus failing to meet the measurement requirements for measuring secondary cell 1.

[0198] For another example, when the SSB configuration of the serving cell changes (such as the duration corresponding to the SSB becomes shorter, or when the SSB is sent in a beam scanning manner and the network side does not send SSBs in some beam directions), the measurement corresponding to the SSB of this cell detected by the UE does not meet the requirements.

[0199] Item 11: The SSB configuration of the serving cell changes.

[0200] For example, when the SSB configuration of the serving cell changes (such as the duration corresponding to the SSB becomes shorter, or when the SSB is sent in a beam scanning manner and the network side does not send SSBs in some beam directions), the UE finds that it cannot detect the required SSB in time, so the UE sends auxiliary information to the network side.

[0201] Optionally, the terminal determines whether the SSB configuration of the serving cell has changed according to the indication of the network side.

[0202] Item 12: The signal quality of the serving cell is greater than a preset quality threshold.

[0203] For example, the terminal works in the Carrier Aggregation (CA) mode and configures a deactivated secondary cell (Scell) 1. For energy-saving purposes, Scell 1 broadcasts SSBs in a more energy-saving manner (such as broadcasting sparse SSBs with an SSB period of 160 ms). When the UE measures that the signal quality of Scell 1 is greater than the preset quality threshold, the UE sends auxiliary information to the network side to trigger the network side to send additional SSBs to assist the UE side to obtain normal services under Scell 1 or to assist the UE side to activate Scell 1.

[0204] Optionally, the network side can pre-configure Scell 1 as a special cell for UE1 (for example, a cell that sends SSBs on demand). When the UE measures that the signal quality of Scell1 is greater than the preset quality threshold, the UE sends auxiliary information to the network side.

[0205] Optionally, when the SSB period (160 ms) of Scell is greater than a certain threshold, or when the SSB period of Scell 1 is less than a certain threshold, if the UE measures that the signal quality of Scell 1 is greater than a preset quality threshold, the UE sends auxiliary information to the network side.

[0206] Item 13: The traffic volume of the terminal is greater than a preset traffic volume threshold, and the traffic volume is the current traffic volume of the terminal;

[0207] For example, the terminal operates in the Carrier Aggregation (CA) mode and configures a deactivated Secondary Cell (Scell) 1. For energy-saving purposes, Scell 1 broadcasts SSB in a more energy-saving manner (such as broadcasting sparse SSB with an SSB period of 160 ms). When the UE discovers that the traffic volume to be transmitted is greater than the preset traffic volume threshold, the UE sends auxiliary information to the network side, triggering the network side to send additional SSB to assist the UE side to obtain normal services under Scell 1 or to assist the UE side to activate Scell 1.

[0208] Optionally, the network side can pre-configure Scell 1 as a special cell for UE1 (for example, a cell that sends SSB on demand). When the UE discovers that the traffic volume to be transmitted is greater than the preset traffic volume threshold, the UE sends auxiliary information to the network side.

[0209] Optionally, when the UE discovers that the traffic volume to be transmitted is greater than the preset traffic volume threshold and the signal quality of Scell 1 is greater than a certain threshold, the UE sends auxiliary information to the network side.

[0210] Optionally, on the basis of including at least one of the above, the above preset conditions may further include: receiving a signaling for activating or deactivating a secondary serving cell.

[0211] For example, the terminal operates in the Carrier Aggregation (CA) mode and configures a deactivated Secondary Cell (Scell) 1. For energy-saving purposes, Scell 1 broadcasts SSB in a more energy-saving manner (such as broadcasting sparse SSB with an SSB period of 160 ms). If the traffic on UE1 increases and more serving cells are needed to provide services for it, the network side sends a signaling to activate Scell 1 to UE1.

[0212] Optionally, the network side can pre-configure Scell 1 as a special cell for UE1 (for example, a cell that sends SSB on demand). After the UE side receives the signaling for activating Scell 1, the UE sends auxiliary information to the network side.

[0213] Optionally, when the SSB period (160 ms) of the Scell is greater than a certain threshold, or when the SSB period of Scell 1 is less than a certain threshold, after receiving the signaling to activate Scell 1, the UE sends auxiliary information to the network side. Here, the SSB period can be the period before receiving the signaling or the period after receiving the signaling.

[0214] Optionally, when the SSB mode (i.e., SSB pattern) of Scell 1 is a certain specific mode (assuming that the SSB mode before Rel19 is the traditional mode, and Rel19 may introduce a compressed SSB mode, such as the duration of SSB transmission within the same period becomes longer, and the network side can configure the SSB mode of Scell 1 as the compressed SSB mode), after the UE receives the signaling to activate Scell 1, UE1 sends auxiliary information to the network side.

[0215] In the embodiments of this application, when preset conditions are met, a first message is sent, and the first message is used to assist the network side device in sending the synchronization signal block (SSB). In the above solution, the terminal sends the first message to assist the network side device in sending the SSB, so that the network side device can efficiently send the SSB on demand based on this first message, thereby reducing the unnecessary transmission of SSBs, and further effectively saving network energy consumption.

[0216] Optionally, the method of the embodiments of this application further includes at least one of the following:

[0217] When receiving a first indication message, determining that the energy-saving mode of the serving cell has changed, where the first indication message is used to indicate that the serving cell enters or exits the energy-saving mode;

[0218] When receiving a second indication message, determining that the SSB mode of the serving cell has changed, where the second indication message is used to indicate that the SSB mode of the serving cell has changed, or is used to indicate that the SSB mode of the serving cell uses the compressed mode or exits the compressed mode;

[0219] When receiving a third indication message, determining that the serving cell is a cell that sends the SSB on demand, where the third indication message is used to indicate that the serving cell is a cell that sends the SSB on demand;

[0220] When receiving a fourth indication message, determining that the serving cell is a cell that sends the SSB on demand, where the fourth indication message is used to indicate that the SSB period of the serving cell has changed or the SSB configuration of the serving cell has changed.

[0221] In an embodiment of the present application, after the terminal determines at least one of a change in the energy-saving mode of the serving cell, a change in the SSB mode of the serving cell, determining that the serving cell is a cell that sends SSBs on demand, and determining that the serving cell is a cell that sends SSBs on demand, the terminal sends first information to the network side to assist the network in configuring the SSB. As a result, the network-side device can efficiently send SSBs on demand based on this first information, thereby reducing the unnecessary transmission of SSBs and effectively saving network energy consumption.

[0222] Optionally, in an embodiment of the present application, the terminal sends the first information through a Radio Resource Control (RRC) message or a Medium Access Control (MAC) Control Element (CE).

[0223] Optionally, the first information includes at least one of the following:

[0224] The layer 3 measurement results of the serving cell, where the layer 3 measurement results include cell-level measurement results and / or beam-level measurement results;

[0225] The layer 1 measurement results of the serving cell, where the layer 1 measurement results include beam-level measurement results;

[0226] The desired SSB configuration, such as the desired SSB period, the desired SSB mode, etc.;

[0227] The SSB configuration index, where the SSB configuration index corresponds to the SSB configuration. Here, the network side needs to pre-send some SSB configurations to the UE in advance. For example, the network side pre-configures multiple SSB configuration lists for the UE. SSB configuration list 1 has an SSB period of 20 ms, an SSB power of 1, and an SSB position configuration 1; SSB configuration list 2 has an SSB period of 320 ms, an SSB power of 2, and an SSB position configuration 2. When the UE sends the first information, according to its own algorithm, it determines the desired SSB configuration, and further determines the desired SSB configuration index according to the SSB configuration list pre-configured by the network side. Among them, the SSB position configuration is used to configure the time domain position of the SSB.

[0228] When the UE is configured with CA, the serving cell here can include only the serving cell that requests to send on-demand SSBs, or can include the primary serving cell and the serving cell that requests to send on-demand SSBs, or can be all active serving cells, or even all serving cells.

[0229] In the embodiments of the present application, the network side configures appropriate SSBs based on the received first information. For example, according to the first information, SSBs are only sent on appropriate beams, and not sent on beam directions where there may be no UEs, thereby reducing the power consumption caused by the network side sending SSBs; or according to the first information, the network side sends denser SSBs (smaller SSB period or longer SSB duration), thereby providing a high-performance SSB configuration when the UE needs it; or according to the first information, the network side determines the SSB configuration expected by the UE and sends appropriate SSBs according to its own algorithm.

[0230] Optionally, the sending of the first information includes:

[0231] Sending the first information through random access resources or uplink signals.

[0232] For example, a random access request is sent through random access resources. The random access request carries the above first information.

[0233] Optionally, there is a corresponding relationship between the above uplink signal and the first information. As an implementation, the corresponding relationship between the uplink signal and the first information can be configured by the network side or agreed upon by the protocol. That is, different first information is implicitly indicated by different uplink signals. Exemplarily, the network side determines, through pre-configuration, that the first information corresponding to an uplink signal is to request the network side to send SSBs on demand or further corresponds to the SSB configuration requested by the UE (or the SSB configuration expected by the UE). In addition, the above signals in the embodiments of the present application can be any signals, and the present application does not make specific limitations thereon. For example, the above uplink signal is a sounding reference signal (SRS).

[0234] In the embodiments of the present application, the network side can pre-configure some random access resources for sending the first information.

[0235] Optionally, the resource location and / or preamble of the random access resources are associated with the expected SSB configuration. For example, resource location 1 of the random access resources corresponds to SSB configuration 1 (for example, SSB period is 20 ms, power value 1 of the SSB, location 1 of the SSB, etc.), and resource location 2 of the random access resources corresponds to SSB configuration 2 (for example, SSB period is 160 ms, power value 2 of the SSB, location 2 of the SSB, etc.). Optionally, the random access resources can be the resources for sending MSG1 corresponding to 4-step RACH, or the resources for sending MSG A corresponding to 2-step RACH.

[0236] In the embodiments of the present application, the terminal may select the resource location and / or preamble of the associated random access resource according to the SSB configuration expected by the terminal to send the first information, that is, implicitly indicate the expected SSB configuration through the resource location and / or preamble of the first information. For example, if the terminal expects the SSB configuration 2, the random access process is triggered at the resource location 2 of the random access resource. After receiving the random access request (which may be MSG1 corresponding to 4-step RACH or MSG A corresponding to 2-step RACH), the network side determines that the UE requests to send the SSB on demand according to the received resource location and / or preamble; optionally, the network side determines the SSB configuration requested (expected) by the UE according to the received resource location and / or preamble. Based on the request, the network side configures a suitable SSB for the UE; optionally, based on the received UE signal, the direction where the UE is located is determined, and the network side may send the SSB only in special directions / locations to reduce network power consumption; optionally, the network side sends the corresponding SSB based on the SSB configuration requested (expected) by the UE.

[0237] Optionally, the terminal sends a signal to the serving cell (such as secondary Scell1) that requests to send the SSB on demand.

[0238] Optionally, the network side sends a random access confirmation message to respond to the random access request sent by the UE.

[0239] Optionally, after receiving the random access confirmation message, the UE receives the updated SSB configuration or receives the updated SSB.

[0240] Optionally, after receiving the random access confirmation message, the UE sets the secondary serving cell (such as secondary Scell1) that requests to send the SSB on demand as the active secondary serving cell.

[0241] Optionally, in the embodiments of the present application, before sending the first information, the method further includes:

[0250] By obtaining at least one of the above information, the terminal determines whether to send the first information for assisting the network side device to send the SSB and / or the content of the first information.

[0251] In the embodiments of the present application, when a preset condition is met, the first information is sent, and the first information is used to assist the network side device to send the synchronization broadcast block SSB. In the above solution, the terminal sends the first information for assisting the network side device to send the SSB, so that the network side device can efficiently send the SSB on demand based on the first information, thereby reducing the unnecessary transmission of SSBs, and further effectively saving network energy consumption.

[0252] As Figure 3 shown, the embodiments of the present application also provide an information transmission method, which is executed by a network side device, and the method includes:
