Description

Information determination and configuration transmission methods, devices, and communication systems Technical Field

[0001] The embodiments of this application relate to the field of communication technology. Background Technology

[0002] As a crucial component of global new infrastructure construction, 5G communication networks have experienced rapid development worldwide in recent years. With the increasing scale of these networks, operators' energy consumption continues to rise. For example, data released by China's Ministry of Industry and Information Technology shows that energy consumption in 2022 will increase by approximately 80% compared to 2015.

[0003] With the deployment of 5G networks and the large-scale commercialization of 5G Active Antenna Units (AAUs), the energy consumption of AAUs will increase exponentially compared to the Remote Radio Units (RRUs) primarily used in 3G and 4G, due to their higher power consumption. 5G defines three major service types: Enhanced Mobile Broadband (eMBB), Massive Machine Type Communication (mMTC), and Ultra Reliable Low Latency Communication (URLLC). This leads to a continuous increase in bursty small-packet traffic in 5G, requiring base stations to operate 24 / 7. Consequently, the average daily energy consumption of 5G sites will be more than double that of 4G.

[0004] In the 5G era, 3GPP introduced key technologies such as Massive MIMO and larger radio frequency bandwidth. 5G supports higher data rates and larger data volumes, requiring more transmission bandwidth, and high-frequency band deployment will be the main frequency band for future 5G expansion. However, the transmission characteristics of high-frequency bands limit the coverage of 5G sites, leading to a denser deployment of 5G sites. Furthermore, the increased energy consumption from additional sites will place significant operational cost pressures on operators. Therefore, network energy saving is crucial for reducing operating costs, making it one of the most pressing issues to be addressed in the 5G and even 6G era.

[0005] To achieve energy savings, network devices can implement energy-saving measures in the time, frequency, spatial, and / or energy domains based on network load. For example, in the spatial and energy domains, network devices can shut down some antennas when the load is low to save energy. In the time domain, network devices can adjust the period or time position of the cell common reference signal (e.g., SSB / SIB) when there are few users and the load is low to achieve energy savings.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0007] The inventors discovered that, in the time domain, for a serving cell that functions solely as a secondary cell, when there is no load and no data transmission is required on the serving cell, network devices can shut down / stop the transmission of the common reference signal (e.g., SSB) of the serving cell to achieve energy saving. When the serving cell is loaded and data transmission is required, the network device activates / triggers the common reference signal of the serving cell through signaling for L1 / L3 measurements of terminal devices, rapid activation of secondary cells, and other operations. This energy-saving method of turning the transmission of the common reference signal on or off according to changes in traffic volume can ensure normal communication of terminal devices while also achieving energy saving for network devices. Determining the power information of on-demand SSBs (e.g., Energy Per Resource Element (EPRE)) or location information has become one of the urgent problems to be solved in network energy-saving technology.

[0057] System message design is a crucial concept in wireless communication systems. Cell-level system messages primarily serve to configure cell camping, provide user access, and facilitate interoperability. 5G NR has simplified system messages to some extent, and its design differs from 4G in terms of synchronization signals and system message design, thus necessitating a re-evaluation.

[0058] Unlike 4G, which separates the cell downlink synchronization signal and the physical broadcast channel, 5G couples the cell synchronization signal (SS) and the physical broadcast channel (PBCH) to some extent, presenting them as SS / PBCH resource blocks, or simply synchronization signal blocks (SSBs).

[0059] Figure 2 is a schematic diagram of the time-frequency structure of SSB. As shown in Figure 2, in 5G NR, SSB occupies 20 consecutive physical resource blocks (PRBs) in the frequency domain, with a maximum of 240 consecutive resource elements (REs). Among them, the synchronization signals (including the primary synchronization signal PSS and the secondary synchronization signal SSS) occupy 127 consecutive REs in the first and third OFDM symbols of SSB, respectively. The frequency domain center position of SSB can be flexibly configured and adjusted according to local conditions.

[0060] After the UE achieves SSB synchronization through frequency search, it decodes the Master Information Block (MIB) in the Physical Broadcast Channel. In LTE systems, in addition to configuring the MIB, the cell also configures SIB1 according to a fixed transmission period, and transmits the necessary parameter configurations for resolving SIB2 to SIBN through SIB1. 5G NR provides an optimized system message configuration mechanism, namely, on-demand configuration; SIB1 is not necessarily configured according to a fixed period in principle. However, SIB1 transmits important information related to cell selection, and even if not configured according to a fixed period, it still needs to be configured semi-statically through RRC signaling. Since the PDCCH carries limited content, and cell-level system messages generally do not change dynamically, PDCCH is generally not used to carry system messages in the design. In 5G NR, configuration is achieved semi-statically through RRC messages.

[0061] The "on-demand" design concept of 5G NR system messages greatly reduces the resource consumption overhead of system messages, while terminal devices can also reduce the power consumption caused by periodically listening to system messages to a certain extent. In 5G NR, the parameter `ssb-SubcarrierOffset` in the MIB determines whether SIB1 is configured in the PDCCH common search space `CORESET#0`. This parameter represents the subcarrier offset of the SSB's frequency domain start position relative to the common PRB. For 5G cell carriers in the FR1 (sub 6GHz) band, the UE, in conjunction with the PBCH, adds 1 bit representing the time domain payload to jointly determine the SSB's subcarrier offset relative to the common PRB, with a value ranging from 0 to 31. If this value is not greater than 23, the UE considers the cell to have configured system message SIB1; otherwise, the SIB1 content does not appear as a system message. For 5G cell carriers in the FR2 band, the UE only uses the parameter `ssb-SubcarrierOffset` to determine the subcarrier offset, with a value ranging from 0 to 15. If this value is not greater than 11, the UE considers the cell to have configured system message SIB1; otherwise, the SIB1 content does not appear as a system message. If this parameter is not configured, the UE determines the SSB's frequency domain subcarrier offset through frequency search.

[0062] 5G NR introduces the concept of shaped narrow beams. The beam pattern is not explicitly defined; within a single SSB transmission cycle, the shaped narrow beams transmitted by the SSB at different candidate transmission times are not identical. The protocol specifies that a maximum of one SSB transmission occurs every 80ms, meaning that the higher-layer content carried by the SSB will not change for at least an 80ms higher-layer scheduling period. The physical layer transmission cycle of the SSB can be configured via the higher-layer parameter `ssb-periodicityServingCell`, with values ​​ranging from {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}. Setting the SSB repetition cycle is primarily for SSB transmission rate matching considerations. A larger cycle means less time-domain resources are occupied by the SSB, potentially lengthening the UE's listening period. If this parameter is not configured, the UE defaults to a 5ms SSB transmission cycle. The protocol stipulates that during initial cell selection, the UE can assume a 20ms cycle to search for half-frames containing SSBs, providing a theoretical basis for optimizing the downlink synchronous network search mechanism.

[0063] For different subcarrier spacings, the candidate positions of the SSB in each half-frame transmission are defined as follows:

[0064] A: With a subcarrier spacing of 15kHz, for NR carrier frequencies within the FR1 band not exceeding 3GHz, the candidate transmission times for the SSB can be configured at the {2, 8} OFDM positions in time slots 0 and 1, resulting in a total of 4 candidate times; while for NR carrier frequencies within the FR1 band exceeding 3GHz, the candidate transmission times for the SSB can be configured at the {2, 8} OFDM positions in time slots 0, 1, 2, and 3, resulting in a total of 8 candidate times.

[0065] B: With a subcarrier spacing of 30kHz, for NR carrier frequencies within the FR1 band not exceeding 3GHz, the candidate transmission times for the SSB can be configured at the {4, 8, 16, 20} OFDM positions calculated starting from slot 0, resulting in a total of 4 candidate times; while for NR carrier frequencies within the FR1 band exceeding 3GHz, the candidate transmission times for the SSB are configured at the {4, 8, 16, 20} OFDM positions calculated starting from slots 0 and 2, resulting in a total of 8 candidate times.

[0066] C: With a subcarrier spacing of 30kHz, in 5G FDD spectrum mode, for NR carrier frequencies within the FR1 band not exceeding 3GHz, the candidate transmission time of the SSB can be configured at the {2, 8} OFDM position in time slots 0 and 1, resulting in a total of 4 candidate times; while for NR carrier frequencies within the FR1 band exceeding 3GHz, the candidate transmission time of the SSB is configured at the {2, 8} OFDM position in time slots 0, 1, 2, and 3, resulting in a total of 8 candidate times. In 5G TDD spectrum mode, for NR carrier frequencies within the FR1 band not exceeding 2.4GHz, the candidate transmission time of the SSB can be configured at the {2, 8} OFDM position in time slots 0 and 1, resulting in a total of 4 candidate times; while for NR carrier frequencies within the FR1 band exceeding 2.4GHz, the candidate transmission time of the SSB is configured at the {2, 8} OFDM position in time slots 0, 1, 2, and 3, resulting in a total of 8 candidate times.

[0067] D: The subcarrier spacing is 120kHz. For the NR carrier frequency within the FR2 band, the candidate transmission times of the SSB are configured in slots 0, 2, 4, 6, 10, 12, 14, 16, 20, 22, 24, 26, 30, 32, 34, and 36, which are the initial calculation OFDM positions {4, 8, 16, 20}, for a total of 64 candidate times.

[0068] E: Subcarrier spacing 240kHz. For NR carrier frequencies within the FR band, the candidate transmission times of SSB are configured in time slots 0, 4, 8, 12, 20, 24, 28, and 32, which are the initial calculated OFDM positions {8, 12, 16, 20, 32, 36, 40, 44}, for a total of 64 candidate times.

[0069] For the SSB candidate location pattern ABCDE transmitted within a half-frame, the UE can determine the specific index position of the currently transmitted SSB by decoding the PBCH payload bits. For a half-frame containing 4 SSB candidate transmission positions, the index is determined using 2 least significant bits (LSB). For a half-frame containing 8 SSB candidate transmission positions, the index is determined using 3 least significant bits (LSB). In both cases, the PBCH index corresponds one-to-one with the initial sequence index of the pseudo-random sequence of the DMRS in the SSB. When determining 2 or 3 least significant bits, the UE does not directly obtain this information by decoding the PBCH transmission bits, but rather indirectly performs a logical mapping by decoding the DMRS. A half-frame contains 64 SSB candidate transmission positions. The DMRS index in the transmitted SSB is mapped cyclically using 3 least significant bits (8 SSB cycles). The UE combines the 3 least significant bits (LSB) with the 3 additional most significant bits (MSB) of the PBCH payload to jointly determine the transmission index of the SSB. The PBCH payload consists of 32 bits, including 23 bits carrying RRC content. Of these 23 bits, 6 bits are used as the high-order 6 bits for calculating the radio frame. In addition to these 23 bits, the physical layer adds 4 bits related to the transmission time as the low-order 4 bits for calculating the radio frame, 1 bit as the half-frame identifier in the radio frame, 3 bits as the high-order 3 bits for determining the SSB index, and the remaining 1 bit is not specified by the protocol. The MAC layer entity fills it in to align with the transmitted bytes.

[0070] Figure 3 is a schematic diagram of SSB candidates. As shown in Figure 3, different frequencies and subcarrier spacings can correspond to different numbers of SSB candidates. For example, when the frequency band is less than or equal to 3 GHz and the subcarrier spacing is 15 kHz, the number of SSB candidates is 4.

[0071] The SSB diagram shows the possible candidate locations of SSBs and the maximum value L of an SSB within the set of SSB bursts. max The actual number of activated SSBs can be less than L. max The base station notifies the UE which SSBs are activated and used via SIB1 or the higher-layer parameter ssb-PositionInBurst in UE-specific RRC signaling. For SSB-related RRC parameters, please refer to relevant technical documentation.

[0072] Network devices can configure a Service-Specific Block (SSB) for a secondary cell, and terminal devices can perform measurements and synchronization operations based on the SSB configured at fixed intervals. Alternatively, network devices can choose not to configure an SSB on the secondary cell, but instead configure a reference cell for it. Terminal devices can then perform measurements and synchronization based on the reference cell's SSB. By default, the reference cell and the current secondary cell are synchronized and co-located. Terminal devices can perform time-frequency synchronization operations for the current secondary cell based on the reference cell's SSB. The above are the relevant regulations for secondary cell SSBs, which support SSB-based QCL reference, SSB-based CSI measurement and reporting, and SSB-based RLM and BFD / BFR.

[0073] The above description illustrates the SSB-related content of the embodiments of this application. This application is not limited thereto, and related technologies can be referenced. Furthermore, the above content, as part of the embodiments of this application, can be combined with the following embodiments.

[0074] Rel-19 network energy-saving technology introduces on-demand SSB cell operation technology, which means that network devices can be configured with on-demand SSB (OD-SSB) in secondary cells. When the cell is unloaded, the network device shuts down / deactivates the OD-SSB to achieve network energy saving. When the cell is loaded, the OD-SSB is activated for terminal device synchronization and measurement.

[0075] The on-demand SSB cell operation technology supports two scenarios: one scenario is that the network device only configures OD-SSB in the cell and can activate / deactivate the OD-SSB; the other scenario is that the network device can configure OD-SSB and always-on SSB at the same time, where always-on SSB is the periodically transmitted SSB in the prior art.

[0076] Therefore, in the two scenarios of on-demand SSB SCell operation technology, how terminal equipment performs downlink power allocation based on on-demand SSB, such as how to determine the ERPE of on-demand SSB and / or the EPRE of CSI-RS based on on-demand SSB, and how to determine the transmission of other channels, such as PUSCH / PUCCH / PRACH, based on the transmission of on-demand SSB, and avoid collisions between on-demand SSB and other channels, are not clearly defined in the existing protocols.

[0077] In the embodiments of this application, higher-layer signaling may be, for example, Radio Resource Control (RRC) signaling; for example, referred to as an RRC message, including MIB, system information, dedicated RRC messages; or referred to as an RRC information element. Higher-layer signaling may also be, for example, Medium Access Control (MAC) signaling; or referred to as a MAC control element. However, this application is not limited to these.

[0078] In the following description, without confusion, the terms "PDCCH" and "Physical Downlink Control Channel" or "Downlink Control Information" are used interchangeably, as are the terms "PDSCH" and "Physical Downlink Data Channel" or "Downlink Data". Furthermore, transmitting or receiving a PDCCH can be understood as transmitting or receiving downlink control information carried by the PDCCH; transmitting or receiving a PDSCH can be understood as transmitting or receiving downlink data carried by the PDSCH.

[0079] In the embodiments of this application, the terms "indication," "activation," and "trigger" can be used interchangeably or in combination; for example, "indication / trigger" can be replaced by "activation / deactivation" or "enable / de-enable," etc. Beam failure detection (BFD) reference signal can be replaced by radio link monitoring reference signal; beam failure recovery (BFR) reference signal can be replaced by candidate beam reference signal.

[0080] First aspect of the embodiments

[0081] This application provides an information determination method, described from the perspective of a terminal device. Figure 4 is a schematic diagram of an information determination method according to an embodiment of this application. As shown in Figure 4, the method includes:

[0082] 401, The terminal device receives (is configured) the first SSB configuration information and / or the second SSB configuration information; and

[0083] 402, the terminal device determines the Energy Per Resource Element (EPRE) of the SSB based at least on the first SSB power parameters included / associated with the first SSB configuration information and / or the second SSB power parameters included / associated with the second SSB configuration information; and / or, the terminal device determines the location information of the SSB based at least on the location parameters within the first SSB burst included / associated with the first SSB configuration information and / or the location parameters within the second SSB burst included / associated with the second SSB configuration information.

[0084] It is worth noting that Figure 4 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 4 above.

[0085] In this embodiment of the application, the network device can configure one or more secondary cells (Scells) for the terminal device through RRC, and can configure SSB (e.g., always-on SSB / CD-SSB and / or on-demand SSB) for one or more secondary cells (Scells).

[0086] For a secondary cell that supports on-demand SSB SCell operation, the network device configures on-demand SSB configuration information based on RRC signaling. The network device can configure one or more lists, each containing multiple pieces of information. Each piece of information is a candidate configuration value or a combination of multiple candidate configuration values. Then, it uses MAC CE, RRC signaling, or DCI signaling to indicate / trigger at least one of the multiple pieces of information as an available value. For example, in the on-demand SSB configuration information based on RRC signaling, the network device configures multiple candidate on-demand SSB period values, and then uses MAC CE, RRC signaling, or DCI signaling to indicate that a period is available / valid.

[0087] In the embodiments of this application, the terms “indicator”, “trigger”, “activate”, “deactivate”, “enable”, “deactivate”, “activate / deactivate” and “enable / deactivate” can be used interchangeably.

[0088] In some embodiments, the SSB includes a first SSB and / or a second SSB; the first SSB is configured as a periodic always-on SSB (AO-SSB); the second SSB is configured as a semi-persistent SSB or an on-demand SSB (OD-SSB). The first SSB is a cell-defined SSB (CD-SSB), or the first SSB can also be a non-cell-defined SSB (NCD-SSB).

[0089] In some embodiments, the terminal device is a UE that supports network power saving (e.g., referred to as a Rel-19 NES capable UE), but this application is not limited thereto. The terminal device in the embodiments of this application supports OD-SSB secondary cell operation, and is at least able to receive OD-SSB-related configurations, and is also able to receive OD-SSB transmission indication / trigger / activation / enable information based on RRC and / or MAC CE and / or DCI; the terminal device is able to perform OD-SSB-based measurements and reporting, such as CSI measurements and reporting, and / or BFD / BFR. For example, the UE capability includes: supporting CSI reporting associated with two CSI resources simultaneously, wherein one CSI resource is AO-SSB, the other CSI resource is OD-SSB, AO-SSB and OD-SSB have the same center frequency, and / or have different center frequencies, and AO-SSB and OD-SSB are within the same BWP.

[0090] The following section will first use an always-on SSB as the first SSB and an on-demand SSB (active OD-SSB) as an example to explain the scenarios supported by the serving cell that supports on-demand SSB secondary cell operation.

[0091] In some embodiments, an on-demand SSB is an SSB triggered by a network device on a secondary cell for Layer 1 / Layer 3 (L1 / L3) measurements; the secondary cell does not transmit an SSB before triggering the on-demand SSB, or the secondary cell transmits an always-on SSB (e.g., CD-SSB of an existing protocol); the network device may indicate / trigger the on-demand SSB based on RRC, MAC CE, or DCI.

[0092] Figure 5 is an example diagram of on-demand SSB triggering according to an embodiment of this application, showing an example where there is no always-on SSB, and the cell indicates / triggers on-demand SSB as needed. As shown in Figure 5, the network device indicates / triggers on-demand SSB when sending the secondary cell activation command, or it can indicate / trigger on-demand SSB during the period when the secondary cell is configured but not yet activated.

[0093] Figure 6 is another example diagram of on-demand SSB triggering according to an embodiment of this application, showing an example of always-on SSB. As shown in Figure 6, on-demand SSB can be indicated / triggered at the time of sending the secondary cell activation command, or it can be indicated / triggered during the period when the secondary cell is configured but not yet activated; always-on SSB exists before or after the on-demand SSB is triggered.

[0094] In the Case#1 scenario shown in Figure 5, the terminal device is configured with an on-demand SSB but not with an always-on SSB. That is, the terminal device will be configured with a second SSB but not with a first SSB. The configuration information of the second SSB may contain at least a portion of all the parameters of the always-on SSB.

[0095] In the Case#2 scenario shown in Figure 6, the terminal device is configured with both on-demand and always-on SSB configurations. This means the terminal device is configured with both a first and a second SSB, and the second SSB configuration information includes some parameters from the always-on SSB. Specifically, if certain parameter values ​​in the second SSB configuration are the same as their corresponding values ​​in the first SSB configuration, those parameters will not appear in the second SSB configuration, and the terminal device will use the corresponding parameter values ​​from the first SSB configuration. Conversely, if the aforementioned parameter values ​​in the second SSB configuration are different from their corresponding values ​​in the first SSB configuration, those parameters will appear in the second SSB configuration, and the terminal device will use the corresponding parameter values ​​from the second SSB configuration.

[0096] In some embodiments, the first SSB configuration includes / is associated with the following high-level parameters: System Information Block Type 1 (SIB1), ServingCellConfigCommon, or NonCellDefiningSSB.

[0097] In some embodiments, the second SSB configuration is named using a newly defined higher-layer parameter, such as od-SSB-config. The second SSB corresponds to / contains / is associated with the secondary cell configuration higher-layer parameter SCellConfig. The second SSB configuration includes at least one of the following parameters:

[0098] The frequency of on-demand SSB (represented by the parameter od-ssb-absoluteFrequency);

[0099] The SSB position within the on-demand SSB burst (represented by the parameter od-ssb-PositionsInBurst);

[0100] On-demand SSB period (represented by the parameter od-ssb-Periodicity);

[0101] The subcarrier spacing of the on-demand SSB (represented by the parameter od-ssbSubcarrierSpacing);

[0102] The temporal location of the on-demand SSB (i.e., the on-demand SSB frame offset and the on-demand SSB half-frame index, represented by the parameters od-ssb-sfn-Offset and od-ssb-halfFrameIndex, respectively);

[0103] Downlink transmission power of on-demand SSB (represented by the parameter od-ss-PBCH-BlockPower);

[0104] The number of on-demand SSB bursts N (i.e., the number of on-demand SSB bursts actually transmitted after on-demand SSB is activated / indicated, represented by the parameter od-ssb-nrofTx).

[0105] In some embodiments, the OD-SSB configuration does not include the parameter N for the number of on-demand SSB bursts, or the number N for on-demand SSB bursts is a special value indicating that the OD-SSB is a periodically transmitted SSB. For example, the special value is an infinite value. Alternatively, the OD-SSB configuration includes the parameter N for the number of on-demand SSB bursts, where N is a positive integer greater than zero, indicating that the OD-SSB is an SSB that is transmitted for a certain period of time and has a finite transmission length.

[0106] In some embodiments, the OD-SSB configuration includes at least one first list, which includes P pieces of information or information IDs, where P represents the maximum number of pieces of information in the first list, and P is a positive integer greater than or equal to 0, for example, P takes the value 2 or 4. The value of the first list is SEQUENCE(SIZE(1..P)) OF information / information ID. The information corresponds to / is a parameter containing information ID and / or OD-SSB period parameters and / or the number of OD-SSB bursts N parameters and / or the time-domain position parameters of OD-SSB and / or the SSB position parameters within the OD-SSB burst and / or the information state indication. The same parameter may have the same value in different pieces of information, or it may have different values. When information contains multiple parameters, the information is a parameter set, which is a combination of multiple parameters. The information can be named OD-SSB sub-configuration. The first list is an OD-SSB sub-configuration list. Each OD-SSB configuration contains an OD-SSB sub-configuration list, which contains P sub-configurations. An OD-SSB sub-configuration contains at least an OD-SSB period. The OD-SSB period values ​​in different OD-SSB sub-configurations can be different or the same.

[0107] For example, the OD-SSB configuration includes a first list containing P pieces of information, each of which contains / corresponds to / is an OD-SSB cycle, and different pieces of information have different values.

[0108] For example, the OD-SSB configuration contains multiple first lists. The first first list contains P pieces of information, each of which contains / corresponds to / an OD-SSB cycle. The second first list contains Q pieces of information, each of which contains / corresponds to / an OD-SSB burst number N parameter. The values ​​of different pieces of information are different.

[0109] For example, the OD-SSB configuration contains only a first list, which contains P pieces of information. Each piece of information is a parameter set, a combination of multiple parameters. For instance, each piece of information might contain / correspond to the OD-SSB period and / or the number of OD-SSB bursts (N parameters) and / or the OD-SSB time-domain location parameter and / or the number of OD-SSB bursts (N parameters). The values ​​of the same parameter in different pieces of information can be the same or different.

[0110] The following is an example. For instance, the first list contains three pieces of information, each containing / being the number N of OD-SSB periods and OD-SSB bursts. In different pieces of information, i.e., different combinations, the value of the number N of OD-SSB periods or OD-SSB bursts can be the same or different.

[0111] --Combination 1:{Periodicity:5ms,Number N:6}

[0112] --Combination 2:{Periodicity:5ms,Number N:10}

[0113] --Combination 3:{Periodicity:20ms,Number N:infinite}

[0114] In some embodiments, the terminal device receives OD-SSB configuration information configured by the network device. The OD-SSB configuration includes at least one first list, wherein one piece of information in the first list is set as default or reference. The default / referenced information of the terminal device is valid / activated / enabled information, and the other information is deactivated / disabled information.

[0115] In some embodiments, the terminal receives OD-SSB configuration information configured by the network device. The OD-SSB configuration includes at least one first list, wherein at least one piece of information in the first list includes status information, which is used to indicate the status of the information, i.e., whether it is an active / enabled / available / valid status or a deactivated / disabled / unavailable status.

[0116] In some embodiments, the second SSB configuration includes at least the number N of on-demand SSB bursts, where N is a positive integer greater than zero. Semi-persistent / aperiodic CSI reporting configurations are associated with the second SSB configuration, and / or periodic CSI reporting configurations are not associated with the second SSB configuration.

[0117] For example, the terminal device receives a second SSB configuration, which is an on-demand SSB configured with RRC. This second SSB configuration includes a parameter (od-ssb-nrofTx) indicating the number of on-demand SSB bursts, N, where N is a positive integer and not infinitely large. By default, the terminal device can associate semi-persistent or aperiodic CSI reporting configurations with the second SSB configuration, but periodic CSI reporting configurations cannot. That is, the second SSB configuration can be a CSI resource associated with a semi-persistent or aperiodic CSI reporting configuration, but it cannot be a CSI resource configuration associated with a periodic CSI reporting configuration.

[0118] In some embodiments, the second SSB configuration includes at least the number N of on-demand SSB bursts, where N is a positive integer greater than zero. Periodic, semi-persistent, and / or aperiodic CSI reporting configurations can be associated with the second SSB configuration. When the periodic CSI reporting configuration is associated with the second SSB configuration, the terminal device defaults to / expects that it will not report CSI after receiving N on-demand SSB bursts, or will report a value of 0 or an invalid value.

[0119] For example, the terminal device receives a second SSB configuration, which is an on-demand SSB configured with RRC. This second SSB configuration includes a parameter (od-ssb-nrofTx) indicating the number of on-demand SSB bursts, N, where N is a positive integer and not infinitely large. The periodic CSI reporting configuration can be associated with the second SSB configuration; that is, the second SSB configuration can be a CSI resource configuration associated with the periodic CSI reporting configuration. The second SSB stops transmitting after transmitting N bursts. The terminal device assumes / expects that it will not perform CSI reporting after N bursts, or that the CSI report will be an invalid value or 0.

[0120] In some embodiments, the terminal device supports on-demand SSB indication / triggering based on RRC and / or MAC CE or DCI, or the terminal device supports on-demand SSB indication, activation / deactivation, and enable / disable based on RRC and / or MAC CE. The OD-SSB indication / activation / enablement is one or more of the P pieces of information in the first list of the OD-SSB indication / activation configuration, and the OD-SSB deactivation / disablement is one or more of the P pieces of information in the first list of the OD-SSB deactivation / disablement configuration.

[0121] In some embodiments, the terminal device receives a MAC CE for activating / deactivating the OD-SSBs of multiple secondary cells. The MAC CE includes at least a Ci field, with the first octet containing the Ci field. The Ci field is a bitmap with a length of N. One Ci corresponds to the OD-SSB activation / deactivation state of a secondary cell with SCellIndex = i. A Ci value of 1 indicates that the on-demand SSB of the secondary cell with SCellIndex = i is activated, and a Ci value of 0 indicates that the on-demand SSB of the secondary cell with SCellIndex = i is deactivated.

[0122] For example, the OD-SSB configuration on a secondary cell includes a first list containing P pieces of information, where P = 2. Each piece of information corresponds to / contains OD-SSB period and / or OD-SSB burst number N parameters and / or OD-SSB transmission location parameters (frame offset, half-frame index) and / or OD-SSB burst location parameters. The MAC CE also includes a Li field. The second octet contains a Li field, which is a bitmap with a length of N. One Li corresponds to an indication of one piece of information in the first list of the OD-SSB configuration of the secondary cell with SCellIndex = i.

[0123] In this embodiment, the first list contains first information and second information. A value of 0 for Li indicates that the first information in the first list of the OD-SSB configuration is indicated / activated / enabled; a value of 1 for Li indicates that the second information in the first list of the OD-SSB configuration is indicated / activated / enabled. Alternatively, a value of 0 for Li indicates that the second information in the first list of the OD-SSB configuration is indicated / activated / enabled; a value of 1 for Li indicates that the first information in the first list of the OD-SSB configuration is indicated / activated / enabled.

[0124] Figure 7 is a schematic diagram of OD-SSB activation / deactivation MAC CE according to an embodiment of this application. In Figure 7, N=7, that is, a maximum of 7 SCells, supporting OD-SSB activation / deactivation of 7 secondary cells. In Figure 7, Oct 1 is the first octet, corresponding to OD-SSB activation / deactivation, and Oct 2 is the second octet, corresponding to the OD-SSB configuration index (optional).

[0125] Figure 8 is another schematic diagram of the OD-SSB activation / deactivation MAC CE according to an embodiment of this application. In Figure 8, N=31, that is, a maximum of 31 SCells, supporting the activation / deactivation of OD-SSB for 31 secondary cells. In Figure 8, Oct 1 to Oct 4 are the first octet, corresponding to OD-SSB activation / deactivation, and Oct 5 to Oct 8 are the second octet, corresponding to the OD-SSB configuration index (optional).

[0126] In some embodiments, the terminal device receives a MAC CE, which is used to indicate / activate a second SSB, and / or, at least to indicate one or more pieces of information from a first list of P pieces of information configured in the second SSB configuration.

[0127] For example, the terminal device can also receive on-demand SSB trigger / indication information from the MAC CE. This MAC CE-based on-demand SSB trigger / indication information indicates that one piece of information in a first list is an available value. For instance, the OD-SSB configuration includes an OD-SSB period list, which contains multiple OD-SSB period candidate values. The MAC CE indicates that one of the OD-SSB period candidate values ​​is a valid / available value. In this case, the OD-SSB transmitted on the serving cell corresponds to the indicated OD-SSB period. If all information in the first list indicated by the MAC CE-based on-demand SSB trigger / indication information is invalid, 0, or unavailable, it indicates that the current OD-SSB is deactivated / disabled, and the serving cell does not transmit OD-SSB.

[0128] In some embodiments, the network device sends OD-SSB trigger / indication information based on MAC CE or RRC, wherein the MAC CE can only implement at most one information from a first list as an available value at any given time.

[0129] For example, a network device configures one on-demand SSB via RRC. This on-demand SSB includes a first list. The information in the first list contains P OD-SSB cycles and / or the number N of OD-SSB bursts and / or the time-domain location parameter of the OD-SSB. Taking the OD-SSB configuration containing a list as an example, each piece of information in the list is the OD-SSB cycle and the number N of OD-SSB bursts. Among the P pieces of information in the list, information 1 contains OD-SSB cycle 1 (or cycle ID = 0, corresponding to a large cycle) and the number N1 of OD-SSB bursts, and information 2 contains OD-SSB cycle 2 (or cycle ID = 1, corresponding to a small cycle) and the number N2 of OD-SSB bursts.

[0130] During SCell activation, network devices need to send frequent, dense on-demand SSBs to achieve rapid activation of the secondary cell. At this time, the network device sends a MAC CE to the terminal device to indicate / trigger / activate / enable OD-SSB period 2 and the number of OD-SSB bursts N2. Once the secondary cell is fully activated, the network device only needs to send sparse, longer-period on-demand SSBs for measurement. At this time, the network device sends a MAC CE to the terminal device to indicate / trigger / activate / enable OD-SSB period 1 and the number of OD-SSB bursts N1, and / or deactivate / deactivate OD-SSB period 2 and the number of OD-SSB bursts N2.

[0131] In some embodiments, the terminal device receives CD-SSB or always-on SSB configuration information configured by the network device. The terminal device also receives OD-SSB configuration information. Some SSB-related characteristics are not included in the OD-SSB configuration information. The terminal device assumes that the characteristics of OD-SSB are the same as those of CD-SSB, and the values ​​of the characteristics of OD-SSB are the same as those of CD-SSB / always-on SSB. Therefore, the values ​​of CD-SSB / always-on SSB can be used and do not need to be included in the OD-SSB configuration. SSB-related characteristics include SSB transmission power and / or SSB, etc.

[0132] In some embodiments, the terminal device sends capability reporting information to the network device. This capability reporting information at least indicates that the terminal device can support OD-SSB secondary cell operation, supports RRC-based OD-SSB and / or MAC CE-based OD-SSB, and that the terminal device can receive OD-SSB configuration information. The terminal device can perform L1 / L3 measurements and reporting based on OD-SSB. Furthermore, the capability reporting information at least indicates the maximum number of second SSB configurations that the terminal device can support / can be configured, or the maximum number of information items in the first list of second SSB configurations; and / or, the terminal device receives capability indication information from the network device, which at least indicates the maximum number of second SSB configurations, or the maximum number of information items in the first list of second SSB configurations.

[0133] For example, the UE can report the maximum number of on-demand SSBs it can support to the base station, and the base station can respond with indication information indicating the maximum number of on-demand SSBs. Alternatively, the UE can report the maximum number of on-demand SSBs it can support to the base station, and the base station will use that maximum number of on-demand SSBs by default. Yet another example is that the base station can directly send indication information indicating the maximum number of on-demand SSBs to the terminal device.

[0134] In this article, OD-SSB and on-demand SSB are interchangeable. The second SSB is the on-demand SSB, and the configuration of the second SSB is the on-demand SSB configuration.

[0135] In some embodiments, OD-SSB (configuration) or second SSB (configuration) may refer to an activated / indicated / triggered OD-SSB (configuration) or second SSB (configuration). The activated / indicated / triggered OD-SSB (configuration) or second SSB (configuration) herein can be interpreted as:

[0136] The terminal device receives at least one OD-SSB configuration based on RRC signaling, and receives RRC or MAC CE or DCI signaling, which is used to activate / indicate / trigger one of the OD-SSB configurations, here being the OD-SSB configuration that is activated / indicated / triggered;

[0137] Alternatively, the terminal device receives an OD-SSB configuration based on RRC signaling, the OD-SSB configuration including a first list, and the terminal device receives RRC or MAC CE or DCI signaling, the signaling being used to activate / indicate / trigger one of the information in the first list. Therefore, the activated / indicated / triggered OD-SSB (configuration) or second SSB (configuration) can be interpreted / understood as the OD-SSB configuration of the RRC configuration, the information being the activated / indicated / triggered information in the first list.

[0138] The above illustrations illustrate some situations of on-demand SSB. In the following description, "SSB parameters" refers to, for example, high-level parameters related to SSB, such as RRC parameters related to SSB, etc., but this application is not limited to these.

[0139] The following describes the downlink power allocation based on on-demand SSB in the embodiments of this application.

[0140] In some embodiments, the first SSB configuration information and the second SSB configuration information are related to the first secondary cell; the first SSB power parameter included in the first SSB configuration information is ss-PBCH-BlockPower, and the second SSB power parameter included in the second SSB configuration information is od-ss-PBCH-BlockPower or ss-PBCH-BlockPower. This application is not limited to this; for example, the power parameter can also be other parameters or use other names.

[0141] In some embodiments, the second SSB is configured in the first secondary cell, but the first SSB is not configured.

[0142] In some embodiments, if the second SSB configuration information includes the second SSB power parameters, then the terminal device determines the energy per resource element (EPRE) of the SSB or the second SSB based at least on the second SSB power parameters included in the second SSB configuration information.

[0143] For example, in Case #1 scenario, the terminal device is configured with on-demand SSB, but not always-on SSB. That is, the terminal device will be configured with the second SSB configuration information, but not the first SSB configuration. During the period when the second SSB configuration is indicated / activated, or during the period when an SSB cycle in the second SSB configuration is indicated / activated, or during the second SSB transmission, the terminal device determines the downlink transmission power or EPRE of the on-demand SSB or SSB based on the downlink power transmission parameters od-ss-PBCH-BlockPower or ss-PBCH-BlockPower in the second SSB configuration.

[0144] In some embodiments, the first SSB and the second SSB are configured in the first secondary cell.

[0145] In some embodiments, the first SSB configuration information includes the first SSB power parameter, while the second SSB configuration information does not include the second SSB power parameter. The terminal device defaults to the second SSB power parameter having the same value as the second SSB power parameter, so this parameter is absent / not included in the second SSB configuration. Therefore, the terminal device determines the Energy Per Resource Element (EPRE) of the SSB or the second SSB based at least on the first SSB power parameter included in the first SSB configuration information.

[0146] For example, in Case #2 scenario, the terminal device is configured with both on-demand SSB and always-on SSB. This means the terminal device is configured with both the first SSB configuration information and the first SSB configuration. The downlink transmission power parameter value for on-demand SSB is the same as that for always-on SSB. Therefore, the second SSB configuration does not include the second SSB power parameter od-ss-PBCH-BlockPower or ss-PBCH-BlockPower. During the period when the second SSB configuration is indicated / activated, or during the period when one SSB cycle in the second SSB configuration is indicated / activated, or during the second SSB transmission, the terminal device determines the downlink transmission power or EPRE of the second SSB (on-demand SSB) based on the ss-PBCH-BlockPower parameter in the first SSB configuration.

[0147] In other embodiments, the first SSB configuration information includes the first SSB power parameter, and the second SSB configuration information includes the second SSB power parameter. Then, during the period when the second SSB configuration is indicated / activated, or during the period when an SSB cycle in the second SSB configuration is indicated / activated, or during the second SSB transmission, the terminal device determines the Energy Per Resource Element (EPRE) of the SSB at least based on the second SSB power parameter included in the second SSB configuration information.

[0148] For example, in Case #2 scenario, the terminal device is configured with both on-demand SSB and always-on SSB. This means the terminal device will be configured with both the first SSB configuration information and the first SSB configuration. The downlink transmission power parameter value for on-demand SSB differs from that for always-on SSB. Therefore, the second SSB configuration includes the second SSB power parameter od-ss-PBCH-BlockPower or ss-PBCH-BlockPower. The terminal device determines the downlink transmission power or EPRE for on-demand SSB based on the downlink power transmission parameter od-ss-PBCH-BlockPower in the second SSB configuration.

[0149] Table 1 shows an example of an embodiment of this application:

[0151] Table 2 shows an example of an embodiment of this application:

[0152] Table 2

[0153] The collision based on on-demand SSB in the embodiments of this application will be described below.

[0154] In some embodiments, the terminal device determines the transmission of the first signal / channel based on location parameters within a first SSB burst and / or a second SSB burst to avoid collisions between the SSB and the first signal / channel. The first signal / channel includes at least one of the following: Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (PRACH), Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), and Sound Reference Signal (SRS).

[0155] In some embodiments, the first SSB configuration information and the second SSB configuration information are related to the first secondary cell; the location parameter within the first SSB burst included in the first SSB configuration information is ssb-PositionsInBurst, and the location parameter within the second SSB burst included in the second SSB configuration information is od-ssb-PositionsInBurst or ssb-PositionsInBurst. This application is not limited to this; for example, the location parameter can be other parameters or use other names.

[0156] In some embodiments, the second SSB is configured in the first secondary cell but the first SSB is not configured.

[0157] In some embodiments, if the second SSB configuration information includes a location parameter within the second SSB burst, then during the period when the second SSB configuration is indicated / activated, or during the period when an SSB cycle in the second SSB configuration is indicated / activated, or during the second SSB transmission, the terminal device determines the time-domain location / symbol of the SSB or the second SSB at least based on the location parameter within the second SSB burst included in the second SSB configuration information.

[0158] For example, in Case #1 scenario, the terminal device is configured with an on-demand SSB but not with an always-on SSB. This means the terminal device will be configured with a first SSB but not with an always-on SSB. The second SSB configuration information includes parameters such as the OD-SSB frequency, the SSB position within the OD-SSB burst, the OD-SSB period, and the OD-SSB SCS. During the period when the second SSB configuration is indicated / activated, or during the period when one SSB period in the second SSB configuration is indicated / activated, or during the second SSB transmission, the terminal device determines the time-domain position / symbol of the SSB / second SSB based on the position parameters od-ssb-PositionsInBurst or ssb-PositionsInBurst within the second SSB burst of the second SSB configuration. This determines the transmission of the first signal / channel, avoiding collisions between the second SSB and the first signal / channel. For example, the first signal / channel may not be transmitted on a symbol or RE during on-demand SSB transmission.

[0159] In some embodiments, the first SSB and the second SSB are configured in the first secondary cell.

[0160] In some embodiments, the first SSB configuration information includes a location parameter within the first SSB burst, while the second SSB configuration information does not include the location parameter within the second SSB burst. The terminal device defaults to the same value for the location parameter within the second SSB burst as the value for the location parameter within the first SSB burst, therefore this parameter is absent / not included in the second SSB configuration. Then, during the period when the second SSB configuration is indicated / activated, or during the period when an SSB cycle in the second SSB configuration is indicated / activated, or during the second SSB transmission, the terminal device determines the time-domain location / symbol of the SSB / second SSB at least based on the first SSB location parameter included in the first SSB configuration information.

[0161] For example, in Case #2 scenario, the terminal device is configured with both on-demand and always-on SSB, meaning it can be configured with both a first and a second SSB. The second SSB configuration does not include the second SSB burst position parameter (od-ssb-PositionsInBurst), while the first and second SSB burst position parameters have the same value. During the period when the second SSB configuration is indicated / activated, or during the period when one SSB cycle in the second SSB configuration is indicated / activated, or during the transmission of the second SSB, the terminal device determines the temporal position / symbol of the second SSB (on-demand SSB) based on the first SSB burst position parameter (ssb-PositionsInBurst) in the first SSB configuration. The terminal device then determines the transmission of the other signals / channels based on the first SSB burst position parameter to avoid collisions.

[0162] In other embodiments, the first SSB configuration information includes a position parameter within the first SSB burst, and the second SSB configuration information includes a position parameter within the second SSB burst. Then, during the period when the second SSB configuration is indicated / activated, or during the period when an SSB cycle in the second SSB configuration is indicated / activated, or during the second SSB transmission, the terminal device determines the time domain position / symbol of the SSB / second SSB at least according to the position parameter within the second SSB burst included in the second SSB configuration information.

[0163] For example, in Case #2 scenario, the terminal device is configured with both on-demand and always-on SSB, meaning it can be configured with both a first and a second SSB. The second SSB configuration includes position parameters within a second SSB burst (od-ssb-PositionsInBurst or ssb-PositionsInBurst), which differ in value from those in the first and second SSB bursts. During the period when the second SSB configuration is indicated / activated, or during the period when an SSB cycle within the second SSB configuration is indicated / activated, or during the transmission of the second SSB, the terminal device determines the temporal position / symbol of the second SSB (on-demand SSB) based on the position parameters within the second SSB burst in the second SSB configuration (od-ssb-PositionsInBurst or ssb-PositionsInBurst). The terminal device then uses these position parameters to determine the transmission of other signals / channels to avoid collisions.

[0164] In some embodiments, for example, an SSB symbol is the symbol where a candidate SSB is located. The index of the candidate SSB is indicated by the first SSB position parameter in the first SSB configuration, i.e., ssb-PositionsInBurst in SIB1, or ssb-PositionsInBurst in ServingCellConfigCommon. Alternatively, during the period when the second SSB configuration is indicated / activated, or during the period when an SSB cycle in the second SSB configuration is indicated / activated, it is indicated by the second SSB position parameter (e.g., od-ssb-PositionsInBurst or ssb-PositionsInBurst) in the second SSB configuration (e.g., od-SSB-Config).

[0165] In some embodiments, the terminal device is configured with a second SSB configuration information on an active downlink BWP. By default, the active downlink BWP of the terminal device includes the second SSB. The collision problem between downlink reception or uplink transmission and the second SSB (on-demand SSB) is the same as the collision problem between downlink reception or uplink transmission and the first SSB. The first SSB is the SS / PBCH blocks provided by SIB1 or ssb-PositionsInBurst in ServingCellConfigCommon.

[0166] In some embodiments, the second SSB is an activated / indicated / enabled OD-SSB, or the second SSB is an OD-SSB that is being transmitted.
