[0049] The embodiments of the present disclosure provide a communication method and apparatus thereof, which can solve the problem of whether a secondary cell supports an on-demand SSB function and / or an SSB-less function, and how to implement support for the on-demand SSB function and / or the SSB-less function.

In the absence of contradiction, each step in a certain embodiment can be implemented as an independent embodiment, and the steps can be arbitrarily combined.

[0064] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0065] In some embodiments, data, information, etc. may be obtained in accordance with the laws and regulations of the country in which the data is obtained. In some embodiments, data, information, etc. may be obtained after obtaining the user's consent.

[0066] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. The communication system may include, but is not limited to, one terminal and one network device. The number and configuration of devices shown in Figure 1 are for example purposes only and do not limit the present disclosure. In practical applications, two or more terminals and two or more network devices may be included. The communication system 100 shown in Figure 1 includes, for example, one terminal 101 and one network device 102.

[0067] It's important to note that with the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, the 3GPP (3rd Generation Partnership Project) international standards organization has begun developing 5G. The main application scenarios for 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). eMBB continues to focus on providing users with multimedia content, services, and data, and demand for it is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly, making a generalized approach difficult and requiring detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. mMTC's key features include high connection density, low data volumes, latency-insensitive services, low module costs, and a long service life.

[0068] Since the energy consumption of 5G base stations is four times that of LTE base stations, network energy saving is an important means for operators to reduce the cost of operating 5G systems. In some embodiments, in order to save energy in the RRC connected state (RRC_CONNECTED) terminal, WUS (wake up signal) is introduced. An offset in front of the on duration of UE C-DRX (Connected Discontinuous Reception) defines a duration for sending a WUS signal. During this WUS duration, the WUS signal, i.e., DCI 2-6, is sent and scrambled by PS-RNTI (Power Saving RNTI) to indicate whether the terminal wakes up to monitor PDCCH (Physical Downlink Control Channel) during the next UE C-DRX onduration.

[0069] In some embodiments, a paging WUS (paging wake-up signal) is introduced to save energy in RRC_IDLE / INACTIVE terminals. This WUS, also known as the PEI (paging early indication), is sent sometime before the paging occasion (PO) to indicate whether the terminal is monitoring paging schedule information at that PO. The PEI is DCI 2-7, scrambled by the PEI-RNTI (paging early indication radio network temporary identifier).

[0070] In some embodiments, Network Energy Saving (NES) already supports SSB-less SCells in inter-band CA scenarios. SSB-less SCells do not send SSBs (Synchronization Signal Blocks). The terminal uses the SSBs of the reference cell to implement time-frequency synchronization, L1 / L3 (Layer 1 / Layer 3) measurements, and SCell activation on the SCell (Secondary Cell). However, SSB-less in inter-band CA scenarios has many limitations. For example, the PCell (Primary Cell) and SCell can only operate in frequency band FR1 when they are co-located. Frequency band FR2 and non-co-site scenarios are not supported.

[0071] In some embodiments, R19 NES supports FR2 and non-co-site scenarios, and on-demand SSB can be used as an enhancement to SSB transmission for scenarios not covered by SSB-less operation to achieve network element gain and ensure appropriate / enhanced SCell functions, including time / frequency synchronization, L1 / L3 measurement, and SCell activation. If the terminal needs to obtain the SSB of the on-demand SSB SCell (SCell that requests SSB on demand), it can request the SSB from the on-demand SSB SCell through the UL WUS (wake up signal). In other words, the SSB of the SCell is sent based on request or on demand.

[0072] However, for the secondary cell supporting the network energy saving (NES) mode in the carrier aggregation scenario, whether it can support the on-demand SSB function and / or the SSB-less function of not sending the synchronization signal block, and how to support the on-demand SSB function and / or SSB-less function, are issues that need to be solved urgently.

[0073] To this end, an embodiment of the present disclosure provides a communication method and an apparatus thereof, which can configure a first parameter and / or a second parameter for a terminal through a network device, so that the terminal obtains a first SSB based on the first parameter and / or the second parameter, so that the terminal can perform corresponding operations on a first secondary cell supporting an on-demand SSB function and / or an SSB-less function through the first SSB, thereby ensuring normal communication between the terminal and the first secondary cell, thereby solving the problem of whether the secondary cell supports the on-demand SSB function and / or the SSB-less function, and how to implement support for the on-demand SSB function / or the SSB-less function.

[0074] Figure 2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the communication method according to the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0075] Step S2101: The network device 102 sends first information of a first secondary cell.

[0076] In some embodiments, the first information of the first secondary cell may be sent by the network device 102 to the terminal 101. For example, the network device 102 sends the first information of the first secondary cell to the terminal 101, and correspondingly, the terminal 101 receives the first information of the first secondary cell sent by the network device 102.

[0077] In some embodiments, the above-mentioned first secondary cell may be a network energy saving (NES) cell, and the first secondary cell supports an on-demand SSB (sending synchronization signal blocks on demand) function and / or an SSB-less (not sending synchronization signal blocks) function. Exemplarily, the on-demand SSB function may refer to sending the first SSB in the first secondary cell based on a request, that is, the first SSB is sent in the first secondary cell based on a request. Exemplarily, the network device 102 may trigger the first secondary cell to send an SSB based on an implementation. Exemplarily, the terminal 101 may request the first secondary cell to send the first SSB to the network device 102. For example, when a certain condition is met, the terminal 101 sends information (such as WUS) to the network device 102 to wake up the first secondary cell to send the first SSB. For example, the terminal 101 determines based on the implementation that it needs to request the first secondary cell to send the first SSB, then the terminal 101 sends information (such as WUS) to the network device 102 to wake up the first secondary cell to send the first SSB. For another example, the terminal 101 measures the RSRP (Reference Signal Receiving Power) of the SSB of the anchor cell. When the measured RSRP is less than or equal to the threshold, the terminal 101 sends information (such as WUS) to wake up the first secondary cell to send the first SSB. For another example, the terminal 101 measures the RSRP of the SSB of the anchor cell, reports the RSRP measurement report to the network device 102, and the network device 102 triggers the first secondary cell to wake up and send the first SSB. For another example, the terminal 101 measures the RSRP of the SSB of the anchor cell, reports the RSRP measurement report to the network device 102, and the network device 102 triggers the terminal 101 to send information (such as WUS) to wake up the first secondary cell to send the first SSB. The anchor cell is an associated cell of the first secondary cell, and the anchor cell can be a normal cell. It should be noted that the implementation method based on the request to send the first SSB in the first secondary cell can also be implemented by other means. This disclosure does not limit this and will not be repeated here.

[0078] Exemplarily, the SSB-less function may mean that the first secondary cell does not send the first SSB, but the terminal 101 obtains the first SSB through a reference cell (referece cell) or a default cell (default cell).

[0079] In some embodiments, the first information is RRC signaling. In some embodiments, the first information may include a first parameter and / or a second parameter. In some embodiments, the first parameter may be a parameter configured for the first secondary cell to support the on-demand SSB function, that is, the first secondary cell needs to configure the first parameter to support sending SSB. The second parameter may be a parameter configured for the first secondary cell to support the SSB-less function. Exemplarily, the first parameter may be named absoluteFrequencySSB, or may be named other names, which is not limited in this disclosure. The second parameter may be named referenceCell, or may be named other names, which is not limited in this disclosure.

[0080] In some embodiments, if the first secondary cell supports both the on-demand SSB function and the SSB-less function, the first parameter may be a mandatory parameter, and the second parameter may be an optional parameter. For example, taking the case where the first secondary cell supports both the on-demand SSB function and the SSB-less function, the network device 102 may configure the first parameter and the second parameter at the same time. If the terminal 101 determines that the on-demand SSB function needs to be used to obtain the first SSB, the terminal 101 obtains the first SSB from the first secondary cell; if the terminal 101 determines that the SSB-less function needs to be used to obtain the first SSB, the terminal 101 may obtain the first SSB from the reference cell indicated by the second parameter. For example, taking the case where the first secondary cell supports both the on-demand SSB function and the SSB-less function, the network device 102 can only configure the first parameter. If it is determined that the on-demand SSB function needs to be used to obtain the first SSB, the terminal 101 obtains the first SSB from the first secondary cell; if the terminal 101 determines that the SSB-less function needs to be used to obtain the first SSB, the terminal 101 can obtain the first SSB from the default cell.

[0081] In some embodiments, the first information of the first secondary cell may be cell information, that is, the network device 102 sends the cell information of the first secondary cell, the cell information may include downlink frequency information, and the downlink frequency information includes the first parameter and / or the second parameter. In some embodiments, the first information may be downlink frequency information, that is, the network device 102 sends the downlink frequency information of the first secondary cell, and the downlink frequency information includes the first parameter and / or the second parameter.

[0082] In some embodiments, the first information may include a first parameter and a second parameter. The initial transmission mode of the first SSB is the first transmission mode, and the first transmission mode of the first SSB means that the first SSB is transmitted in the first secondary cell based on a request, and the initial transmission mode refers to the default transmission mode when adding and / or modifying the first secondary cell. Exemplarily, the initial transmission mode of the first SSB may be preset, or may be agreed upon by a protocol, for example, the protocol stipulates that the initial transmission mode of the first SSB is the first transmission mode; for another example, the initial transmission mode of the first SSB is preset to be the first transmission mode.

[0083] In some embodiments, the first SSB may be used to perform a first operation on the first secondary cell, wherein the first operation may include but is not limited to at least one of the following: timing synchronization; layer 1 (L1) measurement; layer 3 (L3) measurement; SCell activation, etc.

[0084] Step S2102: The network device 102 sends the fifth information.

[0085] In some embodiments, the fifth information may be sent by the network device 102 to the terminal 101. Exemplarily, the network device 102 sends the fifth information to the terminal 101, and correspondingly, the terminal 101 may receive the fifth information sent by the network device 102.

[0086] In some embodiments, the fifth information may include, but is not limited to, at least one of the following: the transmission start time of the first SSB; the transmission duration of the first SSB; and the transmission end time of the first SSB. Exemplarily, upon receiving the fifth information sent by the network device 102, the terminal 101 may monitor the first SSB based on the transmission start time and / or the transmission duration and / or the transmission end time of the first SSB in the fifth information. In some embodiments, the terms "monitor," "detect," "receive," "discover," and "monitor" are interchangeable. Exemplarily, the transmission start time and / or transmission end time may be represented by a radio frame, a radio subframe, a time slot, a time domain symbol, etc. Exemplarily, the transmission start time and / or transmission end time may be a relative time position, such as an offset from the fifth information, indicating the transmission start time and / or transmission end time of the first SSB. Exemplarily, the transmission duration of the first SSB may be measured in hours, minutes, seconds, milliseconds, microseconds, nanoseconds, etc., or in radio frames, radio subframes, time slots, time domain symbols, etc. In some embodiments, the terms "sending start time", "sending start position" and the like can be used interchangeably. In some embodiments, the terms "sending end time", "sending end position" and the like can be used interchangeably.

[0087] In some embodiments, the fifth information may include but is not limited to DCI (Downlink Control Information) and / or MAC CE (Medium Access Control Control Element). Exemplarily, the fifth information may be DCI, or the fifth information may also be MAC CE, indicating the sending start time of the first SSB and / or the sending duration of the first SSB and / or the sending end time of the first SSB through DCI or MAC CE. Exemplarily, the DCI may be a multicast-based DCI, such as CSS (Common Search Space) type 3 (i.e., CSS Type 3).

[0088] In some embodiments, the fifth information can be sent by the network device 102 to the terminal 101 together with the first information of the above-mentioned first secondary cell, or the network device 102 can first send the first information of the first secondary cell and then send the fifth information, or the network device 102 can first send the fifth information and then send the first information of the first secondary cell. This disclosure does not limit this and will not elaborate on it.

[0089] In step S2103, the terminal 101 determines that the sending mode of the first SSB is the first sending mode.

[0090] In some embodiments, the first sending method of the first SSB means that the first SSB is sent in the first secondary cell based on a request, that is: the terminal 101 needs to request the first secondary cell to send the first SSB to the network device 102 in order to obtain the first SSB.

[0091] Exemplarily, it is agreed in the protocol that the initial sending mode of the first SSB is the first sending mode, and the terminal 101 determines that the sending mode of the first SSB is the first sending mode based on the protocol agreement.

[0092] Exemplarily, the initial sending mode of the first SSB is preset as the first sending mode, and the terminal 101 can determine that the sending mode of the first SSB is the first sending mode through pre-configuration.

[0093] Step S2104: Terminal 101 obtains the first SSB sent by network device 102 in the first secondary cell.

[0094] In some embodiments, the transmission mode of the first SSB is the first transmission mode, and the terminal 101 may request the first secondary cell to send the first SSB from the network device 102. Exemplarily, when a certain condition is met, the terminal 101 sends information (such as WUS) to the network device 102 to request the first secondary cell to send the first SSB. For example, the terminal 101 determines based on the implementation that it is necessary to request the first secondary cell to send the first SSB, and the terminal 101 sends information (such as WUS) to the network device 102 to wake up the first secondary cell to send the first SSB. For another example, the terminal 101 measures the RSRP of the SSB of the anchor cell. When the measured RSRP is less than or equal to the threshold, the terminal 101 sends information (such as WUS) to wake up the first secondary cell to send the first SSB. For another example, the terminal 101 measures the RSRP of the SSB of the anchor cell and reports the RSRP measurement report to the network device 102, so that the network device 102 can trigger the first secondary cell to send the first SSB. For another example, the terminal 101 measures the RSRP of the SSB of the anchor cell and reports the RSRP measurement report to the network device 102, so that the network device 102 triggers the terminal 101 to send information (such as WUS) to request the first secondary cell to send the first SSB.

[0095] Exemplarily, the network device 102 receives information (such as WUS) sent by the terminal 101, and the information is used to request the network device 102 to send a first SSB in the first secondary cell. Then, the network device 102 sends the first SSB in the first secondary cell. Accordingly, the terminal 101 can obtain the first SSB sent by the network device 102 in the first secondary cell. Exemplarily, the first SSB can be used to perform timing synchronization on the first secondary cell. Exemplarily, the first SSB can be used to perform L1 measurement on the first secondary cell. Exemplarily, the first SSB can be used to perform L3 measurement on the first secondary cell. Exemplarily, the first SSB can be used to activate SCell on the first secondary cell. It should be noted that the first SSB can also implement other functions on the first secondary cell, which is not limited in this disclosure and will not be described in detail.

[0096] In some embodiments, the sending method of the first SSB is the first sending method, and the network device 102 can trigger the first secondary cell to send the first SSB based on implementation, that is: the network device 102 can send the first SSB in the first secondary cell based on network implementation, and the terminal 101 can obtain the first SSB sent by the network device 102 in the first secondary cell.

[0097] The method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2104.

[0098] In some embodiments, step S2101 and step S2102 may be executed in an interchangeable order or simultaneously.

[0099] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0100] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2A .

As shown in Figure 2B, the communication method according to the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0102] Step S2201: The network device 102 sends first information of a first secondary cell.

[0106] Step S2203: The network device 102 sends the second information.

[0107] In some embodiments, the second information may be sent by the network device 102 to the terminal 101. For example, the network device 102 sends the second information to the terminal 101, and correspondingly, the terminal 101 may receive the second information sent by the network device 102.

[0108] In some embodiments, the second information can be used to adjust the transmission method of the first SSB. In some embodiments, the second information can be RRC (Radio Resource Control) signaling, or it can also be MAC CE or DCI. Exemplarily, the network device 102 can adjust the transmission method of the first SSB through RRC signaling or MAC CE. In some embodiments, the terms such as "adjust", "switch", "change", and "replace" can be used interchangeably.

[0109] It should be noted that, in some embodiments, the second information and the fifth information may be the same information or different information, and this disclosure does not limit this and will not be described in detail.

[0111] Exemplarily, the initial transmission mode of the first SSB is the first transmission mode, and the network device 102 sends second information to the terminal 101. The second information is used to adjust the transmission mode of the first SSB. The terminal 101 receives the second information and adjusts the transmission mode of the first SSB from the initial transmission mode (i.e., the first transmission mode) to the second transmission mode. In some embodiments, the second transmission mode of the first SSB means that the first secondary cell does not send the first SSB. For example, the terminal 101 can obtain the first SSB through a reference cell (referece cell) or a default cell (default cell).

[0112] In step S2205, the terminal 101 determines that the sending mode of the first SSB is the second sending mode.

[0113] Step S2206: Terminal 101 obtains the first SSB sent by the reference cell indicated by the second parameter.

[0114] In some embodiments, the transmission mode of the first SSB is the second transmission mode, and the terminal 101 obtains the first SSB transmitted by the reference cell indicated by the second parameter. Exemplarily, the initial transmission mode of the first SSB is the first transmission mode, and the terminal 101 receives the second information sent by the network device 102, and adjusts the transmission mode of the first SSB from the initial transmission mode (i.e., the first transmission mode) to the second transmission mode, that is, the transmission mode of the first SSB is changed to the second transmission mode, then the terminal 101 can obtain the first SSB through the reference cell indicated by the second parameter.

When the first indication information takes the fourth value, it indicates that the SSB-less function is enabled in the first secondary cell, that is, the sending mode of the first SSB is the second sending mode. When the first indication information is the fifth value or the sixth value, it indicates that the on-demand SSB and SSB-less functions are enabled in the first secondary cell, that is, the transmission mode of the first SSB can be the first transmission mode or the second transmission mode.

Exemplarily, the network device 102 indicates through the first indication information that the on-demand SSB function and the SSB-less function are enabled in the first secondary cell, then the network device 102 can also reconfigure the on-demand SSB function to be enabled in the first secondary cell through RRC signaling (that is, the on-demand SSB function and the SSB-less function are enabled in the first secondary cell through RRC signaling, and are adjusted to enable the on-demand SSB function in the first secondary cell), or reconfigure the SSB-less function to be enabled in the first secondary cell through RRC signaling (that is, the on-demand SSB function and the SSB-less function are enabled in the first secondary cell through RRC signaling, and are adjusted to enable the SSB-less function in the first secondary cell).

Exemplarily, after the network device 102 reconfigures the SSB-less function in the first secondary cell through RRC signaling, the terminal 101 may determine that the transmission mode of the first SSB is the second transmission mode. If the second parameter is configured, the terminal 101 may obtain the first SSB sent by the reference cell indicated by the second parameter. If the second parameter is not configured and only the first parameter is configured, the terminal 101 may obtain the first SSB sent by the default cell. Exemplarily, after the network device 102 is reconfigured through RRC signaling to enable the on-demand SSB function and the SSB-less function in the first secondary cell, if the second parameter is configured, the terminal 101 determines based on the terminal 101 implementation to obtain the first SSB sent by the network device 102 in the first secondary cell or obtains the first SSB from the reference cell indicated by the second parameter; if the second parameter is not configured and only the first parameter is configured, the terminal 101 determines based on the terminal 101 implementation to obtain the first SSB sent by the network device 102 in the first secondary cell or obtains the first SSB from the default cell.

[0286] It is worth noting that the present disclosure provides a method for switching the SSB transmission mode, which solves the problem of whether the on-demand SSB SCell in R19 can support the SSB-less function at the same time and how to achieve simultaneous support of the on-demand SSB and SSB-less functions. The following is a detailed description with reference to the embodiments.

[0287] Example 1: On-demand SSB SCell can be configured / supported simultaneously with the functions of sending SSB on request and SSB-less.

[0288] For example, an on-demand SSB SCell can be configured with both the absoluteFrequencySSB parameter (cells that support SSB transmission need to configure this parameter) and the referenceCell parameter (R18 SSB-less cells do not configure absoluteFrequencySSB, but can configure referenceCell. If referenceCell is not configured, the terminal uses the default cell to obtain timing synchronization). For example, absoluteFrequencySSB (such as the first parameter in this article) is a required parameter. For example, referenceCell (such as the second parameter in this article) is an optional parameter.

[0289] Exemplarily, the first parameter and the second parameter are configured together, and the initial transmission mode of the SSB of the SCell is on-demand SSB. Exemplarily, the first parameter and the second parameter are configured together, and the initial transmission mode of the SSB of the SCell is SSB-less. Exemplarily, the network device can adjust the transmission mode of the SSB of the SCell through RRC signaling or MAC CE, for example, from on-demand SSB to SSB-less, or from SSB-less to on-demand SSB. The terminal determines whether to obtain timing synchronization from the reference cell or from the SSB sent on-demand through implementation.

[0290] Embodiment 2 defines first indication information, which is used to indicate whether the SSB-less function and / or the on-demand SSB function is enabled.

[0291] Exemplarily, the two parameters absoluteFrequencySSB and referenceCell are configured at the same time, and the first indication information indicates whether to enable the SSB-less function and / or the on-demand SSB function.

[0292] Example A, the first indication information can have 1 bit. For example, when the first indication information takes the value of enable or the first value, it is not specifically limited and is used to indicate that the SSB-less function is enabled, the SSB sending mode of the SCell is SSB-less, and the terminal obtains timing synchronization through the referenceCell; when the first indication information is default, it is used to indicate that the on-demand SSB function is enabled, the SSB sending mode of the SCell is on-demand SSB, and the terminal obtains timing synchronization through on-demand SSB.

[0293] Example B, the first indication information can have 1 bit. For example, when the first indication information takes the value of enable or the first value, it is not specifically limited and is used to indicate that the on-demand SSB function is enabled, the SCell sends SSB in an on-demand SSB manner, and the terminal obtains timing synchronization through on-demand SSB; when the first indication information is default, it is used to indicate that the SSB-less function is enabled, the SSB sending manner of the SCell is SSB-less, and the terminal obtains timing synchronization through the referenceCell.

[0294] Example C, the first indication information can have 1 bit. When the first indication information takes a first value (such as 0), the on-demand SSB function is enabled, the SCell sends SSB in an on-demand SSB manner, and the terminal obtains timing synchronization through on-demand SSB; when the first indication information takes a second value (such as 1), the SSB-less function is enabled, the SCell sends SSB in an SSB-less manner, and the terminal obtains timing synchronization through referenceCell.

[0295] Example D, the first indication information is 2 bits. When the first indication information is the third value (such as 00), the on-demand SSB function is enabled, the SCell sends SSB in an on-demand SSB manner, and the terminal obtains timing synchronization through on-demand SSB; when the first indication information is the fourth value (such as 01), the SSB-less function is enabled, the SCell sends SSB in an SSB-less manner, and the terminal obtains timing synchronization through the referenceCell. When the first indication information is the fifth value (such as 10 or 11), the on-demand SSB and SSB-less functions are enabled, and the SCell sends SSB in an on-demand SSB or SSB-less manner. The terminal determines whether to obtain timing synchronization through on-demand SSB or through the referenceCell based on the implementation.

[0296] Exemplarily, only absoluteFrequencySSB is configured, and referenceCell is not configured, and the first indication information is used to indicate whether the SSB-less function and / or on-demand SSB function is enabled. Exemplarily, the first indication information may have 1 bit. Exemplarily, when the first indication information takes the value of enable or the first value, without specific limitation, it is used to indicate that the SSB-less function is enabled, the SSB sending mode of the SCell is SSB-less, and the terminal obtains timing synchronization through the default cell or SpCell or SCell; when the first indication information is default, it is used to indicate that the on-demand SSB function is enabled, the SSB sending mode of the SCell is on-demand SSB, and the terminal obtains timing synchronization through on-demand SSB.

[0297] In Embodiment 3, the network device indicates the transmission start time and / or transmission duration and / or transmission end time of the SSB through DCI or MAC CE. Exemplarily, the transmission start time and / or transmission duration and / or transmission end time of the SSB can be indicated through DCI or MAC CE. Exemplarily, the DCI can be multicast-based DCI, such as CSS type 3.
