[0002] This application claims priority to Chinese Patent Application No. 201810760126.7, filed in China on July 11, 2018, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, specifically to a signal processing method and device. Background Technology

[0004] In New Radio (NR) systems, base stations need to send Synchronization Signal Blocks (SSBs) for terminal devices to synchronize, acquire system information, and perform measurements.

[0005] The base station can notify the terminal device which SSBs it actually transmitted through Remaining Minimum System Information (RMSI) (also known as System Information Block 1 (SIB1)) and Radio Resource Control (RRC) signaling.

[0006] However, the SSBs actually transmitted by the base station indicated by RMSI and RRC may be different. In this case, user terminal equipment in different states (such as connected state and idle state) may have different understandings of the allocation of physical channel (or physical signal) resources according to different SSB indications. Furthermore, according to different SSB indications, the understanding of the correlation between physical channel (or physical signal) and actual transmitted SSB may also be different. This may lead to resource waste and increase the complexity of system resource configuration.

[0007] Summary of the Invention

[0035] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0036] The term "comprising," and any variations thereof, used in the specification and claims of this application, is intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus. Furthermore, the use of "and / or" in the specification and claims indicates at least one of the connected objects, such as A and / or B, indicating the inclusion of A alone, B alone, or both A and B.

[0037] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0038] To better understand the technical solutions of the embodiments of this disclosure, the following technical points are first introduced:

[0039] I. Regarding SSB instructions:

[0040] In NR systems, base stations need to send SSBs (Service Streaming Buses) for terminal devices to perform synchronization, system information acquisition, and measurements. Multiple SSBs form an SS burst set. The maximum number of SSBs contained in an SS burst set is related to the carrier frequency used by the network.

[0041] When the carrier frequency range is less than 3 GHz, a single SS burst set can contain a maximum of 4 SSBs;

[0042] When the carrier frequency range is 3GHz to 6GHz, a single SS burst set can contain a maximum of 8 SSBs;

[0043] When the carrier frequency range is above 6 GHz, a single SS burst set can contain a maximum of 64 SSBs.

[0044] Understandably, regardless of the number of SSBs in an SS burst set, all SSBs in that SS burst set must be transmitted within a 5-millisecond (ms) time window. However, the actual number of SSBs transmitted by the base station within the 5ms time window may be less than the maximum number of SSBs that can be contained in the previous SS burst set in that frequency band. The base station can notify the terminal device of which SSBs it actually transmitted via RMSI (also known as SIB1) and / or RRC signaling.

[0045] The SSB information indicating the actual transmission in the RRC signaling is designed as follows:

[0046]

[0047] The SSB information that indicates the actual transmission in the RMSI is designed as follows:

[0048]

[0049]

[0050] In frequency bands above 6 GHz, when a base station uses RMSI to indicate the actual transmitted SSB information, it employs an 8-bit group bitmap and an 8-bit intra-group bitmap. An SSB group is defined as multiple consecutive SSBs. The group bitmap indicates which SSB groups were actually transmitted (whether they exist), and the intra-group bitmap indicates which SSBs within those groups were actually transmitted (whether they exist). The number of SSBs actually transmitted within each group is the same. For example, for frequencies above 6 GHz, an SS burst set can contain a maximum of 64 SSBs. These 64 potentially transmitted SSBs are divided into 8 groups. A group bitmap of "11000000" indicates that the base station actually transmitted the first and second SSB groups. An intra-group bitmap of "11110000" indicates that the base station actually transmitted the first four SSBs within the first and second SSB groups. Therefore, the base station transmitted a total of 2 × 4 = 8 SSBs.

[0051] When the base station uses RRC signaling to notify the terminal device of the actual SSBs transmitted, it uses a full bitmap. That is, when an SS burst set can contain a maximum of L SSBs (L = 4 / 8 / 64), a bitmap of length L is used to indicate which SSBs are actually transmitted.

[0052] II. The relationship between SSB and Physical Random Access Channel transmission timing (PRACH Transmission Occasion, or PRACH Occasion, RO):

[0053] In an NR system, the association between an SSB and a RO refers to a mapping between them. This mapping can be one-to-one, one-to-many, or many-to-one. An example is when two SSBs are mapped to RO resources, with one SSB mapped to each RO. Assuming the two SSBs associated with the RO are SSB0 and SSB1, then within one SSB-RO mapping, SSB0 and SSB1 are mapped to two different ROs. The terminal device can determine the association between SSBs and ROs based on the SSB and PRACH configurations indicated in the RRC and / or RMSI.

[0054] The embodiments of this disclosure are described below with reference to the accompanying drawings. The signal processing method and apparatus provided in the embodiments of this disclosure can be applied to a wireless communication system. This wireless communication system can be a fifth-generation (5G) system, an evolved long-term evolution (eLTE) system, or a subsequent evolution communication system. Referring to Figure 1, it is a schematic diagram of the architecture of a wireless communication system provided in an embodiment of this disclosure. As shown in Figure 1, the wireless communication system may include: a network-side device 10 and a terminal device (e.g., a user equipment (UE)). For example, the terminal device is denoted as UE11, and UE11 can communicate with the network-side device 10 (transmit signaling or transmit data). In practical applications, the connection between the above-mentioned devices can be a wireless connection. To conveniently and intuitively represent the connection relationship between the devices, solid lines are used in Figure 1.

[0055] It should be noted that the above communication system may include multiple UE11, and the network-side device 10 may communicate with multiple UE11.

[0056] The network-side device 10 provided in this embodiment can be a base station. The base station can be a commonly used base station, an evolved node base station (eNB), or a network-side device in a 5G system (e.g., a next-generation node base station (gNB) or a transmission and reception point (TRP)).

[0057] The user equipment provided in this disclosure can be a mobile phone, tablet computer, laptop computer, Ultra-Mobile Personal Computer (UMPC), netbook, or Personal Digital Assistant (PDA), etc.

[0058] Referring to Figure 2, this disclosure provides a signal processing method, the execution subject of which is a network-side device, and the steps are as follows:

[0059] Step 201: Send the first information via RMSI; and / or, send the second information via RRC signaling;

[0060] In this embodiment, the SSB-related information indicated by the first indication information and the SSB-related information indicated by the second indication information are at least partially identical. Optionally, the SSB-related information indicated by the first indication information and the SSB-related information indicated by the second indication information are completely identical. In this embodiment, the network side can guarantee and / or the terminal device expects (assuming) that the SSB-related information indicated by the first indication information and the SSB-related information indicated by the second indication information are completely identical.

[0061] For example: the first indication information and the second indication information indicate the time position of the SSB transmitted in the burst set, and the time position of the transmitted SSB is used for rate matching; or, the first indication information and the second indication information indicate the SSB that is associated with the RO, and the indicated SSB is used for the association between the SSB and the RO.

[0062] In this embodiment of the disclosure, since the SSB-related information indicated by the first indication information is at least partially consistent with the SSB-related information indicated by the second indication information, the terminal device can determine the content indicated by the second indication information based on the first indication information, or determine the content indicated by the first indication information based on the second indication information, thereby ensuring that the terminal devices in different states (e.g., connected state and idle state) have a consistent understanding of the SSB indicated by RMSI and / or RRC.

[0063] It is understandable that the SSB-related information indicated by the first instruction information is the same as that indicated by the second instruction information, or there is a certain mapping relationship, or there is a derivation rule, that is, the SSB-related information indicated by the first instruction information is derived from the SSB-related information indicated by the second instruction information, or the SSB-related information indicated by the second instruction information is derived from the SSB-related information indicated by the first instruction information.

[0064] In the embodiments disclosed herein, the first information and the second information may have the same format. It is understood that the use of the same format for the first information and the second information is not specifically limited.

[0065] Optionally, in embodiments of this disclosure, the first information may indicate at least one of the following: the first time location of the SSB transmitted in the burst concentration; and the first SSB that is associated with the physical random access channel transmission timing RO;

[0066] The second information indicates at least one of the following: the second time location of the SSB transmitted in the burst; and a second SSB that is associated with the RO;

[0067] Wherein, the first time position and the second time position are at least partially consistent, and / or, the first SSB and the second SSB are at least partially consistent.

[0068] For example, the first information may include one or more of the following: parameter a, parameter b, and parameter c, wherein parameter a indicates the first time position of the SSB transmitted in the burst set, parameter b indicates the first SSB that is associated with the Physical Random Access Channel transmission timing RO, and parameter c indicates the first time position of the SSB transmitted in the burst set and the first SSB that is associated with the Physical Random Access Channel transmission timing RO.

[0069] For example, the second information may include one or more of the following: parameter d, parameter e, and parameter f, wherein parameter d indicates the first time position of the SSB transmitted in the burst set, parameter e indicates the first SSB that is associated with the Physical Random Access Channel (PRAN) transmission timing RO, and parameter f indicates the first time position of the SSB transmitted in the burst set and the first SSB that is associated with the PRAN transmission timing RO.

[0070] Furthermore, for example, the first information includes parameter c, and the second information includes parameters d and e, with the network side ensuring that parameters c and e are the same. Alternatively, the first information includes parameter c, and the second information includes parameter f, with the network side ensuring that parameters c and f are the same.

[0071] It is understandable that the first time position and the second time position are at least partially the same, or that the first time position and the second time position have at least a certain mapping relationship, or that the first time position and the second time position have at least a derivation rule, that is, the second time position is derived from the first time position, or the first time position is derived from the second time position.

[0072] It is understandable that the first SSB and the second SSB are at least partially the same, or that the first SSB and the second SSB have a certain mapping relationship, or that the first SSB and the second SSB have a derivation rule, that is, the second SSB is derived from the first SSB, or the first SSB is derived from the second SSB.

[0073] In this embodiment of the disclosure, optionally, the first information and the second information are the position parameter of the synchronization signal block in the burst set (SSB - PositionsInBurst) or other parameters characterizing the time domain position of the SSB transmission. It is understood that the form of the first information and the second information is not specifically limited.

[0074] In this embodiment of the disclosure, optionally, in step 201, the first information is sent via the RMSI of the target cell, secondary cell (Scell), or primary-secondary cell (PScell); or, the second information of the target cell, secondary cell, or primary-secondary cell is sent via RRC signaling. For example, in an inter-cell handover scenario, the source cell sends the second information of the target cell via RRC signaling. As another example, in a scenario of adding or modifying a serving cell, the added or modified serving cell sends the second information of the secondary cell or primary-secondary cell via RRC signaling.

[0075] In this embodiment of the disclosure, optionally, in an inter-cell handover scenario, the first information is sent by the target cell and the second information is sent by the source cell; or, in a scenario of adding or modifying a serving cell, the first information is sent by the serving cell being added or modified, and the second information is sent by the primary cell, specifically including: (1) in a scenario of adding or modifying a secondary cell configuration, the first information is sent by the secondary cell and the second information is sent by the primary cell; (2) in a scenario of adding or modifying a primary and secondary cell configuration, the first information is sent by the primary and secondary cells, and the second information is sent by the primary cell. Optionally, in an inter-cell handover scenario or in a scenario of adding or modifying a serving cell, the SSB-related information indicated by the first and second information can be completely identical. For example, when the conditions for inter-cell handover and serving cell addition (HOAndServCellAdd) exist, the SSB-related information indicated by the first and second information can be completely identical.

[0076] In the embodiments of this disclosure, in inter-cell handover scenarios, in scenarios of adding or modifying secondary cell configurations, or in scenarios of adding or modifying primary and secondary cell configurations, the network can ensure that the SSB-related information indicated by the first information sent via RMSI and the second information sent via RRC signaling is at least partially consistent. This ensures that terminal devices in different states (e.g., connected state and idle state) have a consistent understanding of the association between physical channels (or physical signals) and SSBs based on the SSBs indicated by RMSI and / or RRC, thereby avoiding resource waste and reducing the complexity of system resource configuration.

[0077] Referring to Figure 3, this disclosure also provides a signal processing method, which is executed by a terminal device, and the specific steps are as follows:

[0078] Step 301: Receive the first information via RMSI; and / or receive the second information via RRC signaling;

[0079] Wherein, the SSB-related information indicated by the first indication information and the SSB-related information indicated by the second indication information are at least partially consistent. Optionally, the SSB-related information indicated by the first indication information and the SSB-related information indicated by the second indication information are completely identical. In the embodiments of this disclosure, the network side can guarantee and / or the terminal device expects (assuming) that the SSB-related information indicated by the first indication information and the SSB-related information indicated by the second indication information are completely identical. For example: the first indication information and the second indication information indicate: the time position of the SSB transmitted in the burst concentration, which is used for rate matching; or, the first indication information and the second indication information indicate: an SSB that has an association with the RO, which is used for the association between the SSB and the RO.

[0080] In this embodiment of the disclosure, since the SSB-related information indicated by the first indication information is at least partially consistent with the SSB-related information indicated by the second indication information, the terminal device can determine the content indicated by the second indication information based on the first indication information, or determine the content indicated by the first indication information based on the second indication information, thereby ensuring that the terminal devices in different states (e.g., connected state and idle state) have a consistent understanding of the SSB indicated by RMSI and / or RRC.

[0081] It is understandable that the SSB-related information indicated by the first instruction information is the same as that indicated by the second instruction information, or there is a certain mapping relationship, or there is a derivation rule, that is, the SSB-related information indicated by the first instruction information is derived from the SSB-related information indicated by the second instruction information, or the SSB-related information indicated by the second instruction information is derived from the SSB-related information indicated by the first instruction information.

[0082] In the embodiments disclosed herein, the first information and the second information may have the same format. It is understood that the use of the same format for the first information and the second information is not specifically limited.

[0083] Optionally, in embodiments of this disclosure, the first information may indicate at least one of the following: the first time location of the SSB transmitted in the burst concentration; and the first SSB that is associated with the physical random access channel transmission timing RO;

[0084] The second information indicates at least one of the following: the second time location of the SSB transmitted in the burst; and a second SSB that is associated with the RO;

[0085] Wherein, the first time position and the second time position are at least partially consistent, and / or, the first SSB and the second SSB are at least partially consistent.

[0086] It is understandable that the first time position and the second time position are at least partially the same, or that the first time position and the second time position have at least a certain mapping relationship, or that the first time position and the second time position have at least a derivation rule, that is, the second time position is derived from the first time position, or the first time position is derived from the second time position.

[0087] It is understandable that the first SSB and the second SSB are at least partially the same, or that the first SSB and the second SSB have a certain mapping relationship, or that the first SSB and the second SSB have a derivation rule, that is, the second SSB is derived from the first SSB, or the first SSB is derived from the second SSB.

[0088] Optionally, in the embodiments disclosed herein, the first information and the second information are SSB-PositionsInBurst parameters or other parameters characterizing the time-domain position of SSB transmission. It is understood that the form of the first information and the second information is not specifically limited.

[0089] Optionally, in step 301, the first information is received via the RMSI of the target cell, secondary cell, or primary / secondary cell; or the second information of the target cell, secondary cell, or primary / secondary cell is received via RRC signaling.

[0090] In this embodiment of the disclosure, optionally, in an inter-cell handover scenario, the first information is sent by the target cell and the second information is sent by the source cell; or, in a scenario of adding or modifying a serving cell, the first information is sent by the serving cell being added or modified, and the second information is sent by the primary cell, specifically including: (1) in a scenario of adding or modifying a secondary cell configuration, the first information is sent by the secondary cell and the second information is sent by the primary cell; (2) in a scenario of adding or modifying a primary and secondary cell configuration, the first information is sent by the primary and secondary cells, and the second information is sent by the primary cell. Optionally, in an inter-cell handover scenario or in a scenario of adding or modifying a serving cell, the SSB-related information indicated by the first and second information can be completely identical. For example, when the HOAndServCellAdd condition exists, the SSB-related information indicated by the first and second information can be completely identical.

[0091] In the embodiments of this disclosure, in inter-cell handover scenarios, in scenarios of adding or modifying secondary cell configurations, or in scenarios of adding or modifying primary and secondary cell configurations, the network can ensure that the SSB-related information indicated by the first information sent via RMSI and the second information sent via RRC signaling is at least partially consistent. This ensures that terminal devices in different states (e.g., connected state and idle state) have a consistent understanding of the association between physical channels (or physical signals) and SSBs based on the SSBs indicated by RMSI and / or RRC, thereby avoiding resource waste and reducing the complexity of system resource configuration.

[0092] It is understood that the embodiments disclosed herein can solve the problems that arise in the following scenarios:

[0093] Scenario 1: During inter-cell handover, the ssb-PositionsInBurst associated with the target cell carried in the signaling of the current serving cell (e.g., the source cell) is different from the ssb-PositionsInBurst in the RMSI of the target cell.

[0094] Scenario 2: When adding or modifying the Scell ​​configuration, the ssb-PositionsInBurst carried in the signaling of the current serving cell (e.g., the primary cell) and associated with the secondary cell (Scell) is different from the ssb-PositionsInBurst in the RMSI of the Scell.

[0095] Scenario 3: When adding or modifying the configuration of a Primary Secondary Cell (PScell), the ssb-PositionsInBurst associated with the PScell ​​carried in the signaling of the current serving cell (e.g., the primary cell) is different from the ssb-PositionsInBurst in the RMSI of that PScell.

[0096] In response to the above scenario, this embodiment of the disclosure can ensure that the ssb-PositionsInBurst of the target cell, Scell ​​cell or PScell ​​carried in the signaling of the current serving cell is the same as the ssb-PositionsInBurst in the RMSI of the target cell, Scell ​​cell or PScell.

[0097] Example 1:

[0098] In this example, the first information and the second information are described as ssb-PositionsInBurst parameters. It is understood that the specific form of the first information and the second information is not specifically limited in this embodiment.

[0099] When performing inter-cell handover, adding or modifying Scell ​​configuration, or adding or modifying Pscell configuration, the base station ensures that the SSB indicated by ssb-PositionsInBurst in the ServingCellConfigCommon configuration for the target cell, Scell ​​cell, or PScell ​​is the same as the SSB indicated by ssb-PositionsInBurst in the SIB1 of the target cell, Scell ​​cell, or PScell ​​cell.

[0100] For example, for 6G and above, a single SS burst set can contain a maximum of 64 SSBs, which are divided into 8 groups. In an inter-cell handover scenario, assuming the group bitmap of ssb-PositionsInBurst in the RMSI of target cell A is "11000000", indicating the first and second SSB groups, and the intra-group bitmap is "11000000", representing the first two SSBs within the first and second SSB groups, the base station transmits a total of 2 × 2 = 4 SSBs, which are numbered SSB0, SSB1, SSB8, and SSB9. Considering inter-cell handover, the RRC configuration (e.g., ReconfigurationWithSync) of source cell B includes the configuration of target cell A. In this case, the ssb-PositionsInBurst in the ServingCellConfigCommon of the network configuration also indicates SSB0, SSB1, SSB8, and SSB9. The terminal device establishes an association between SSB and RO based on SSB0, SSB1, SSB8 and SSB9, and performs rate matching based on SSB0, SSB1, SSB8 and SSB9.

[0101] For example, for 6G and above, an SS burst set can contain a maximum of 64 SSBs. These 64 potentially transmitted SSBs are divided into 8 groups. The Pcell configures cell A as a newly added secondary cell for the user via signaling. Assume that cell A is also sending the RMSI of cell A, and the group bitmap of ssb-PositionsInBurst in the RMSI (SIB1) of the RMSI is "11000000", indicating the first and second SSB groups. The bitmap within the group is "11000000", indicating the first two SSBs in the first and second groups. Therefore, a total of 2×2=4 SSBs are transmitted, assuming they are numbered SSB0, SSB1, SSB8, and SSB9. At this time, the network needs to ensure that the ssb-PositionsInBurst indication in the configuration (e.g., ServingCellConfigCommon) for the secondary cell A in the signaling sent by the primary cell is also SSB0, SSB1, SSB8, and SSB9. The terminal device establishes an association between SSB and RO based on SSB0, SSB1, SSB8 and SSB9, and performs rate matching based on SSB0, SSB1, SSB8 and SSB9.

[0102] Alternatively, for example, for 6G and above, an SS burst set can contain a maximum of 64 SSBs. These 64 potentially transmitted SSBs are divided into 8 groups. The Pcell configures cell A as a primary or secondary cell for the user via signaling. Assume that cell A is also sending the RMSI of cell A, and the group bitmap of ssb-PositionsInBurst in the RMSI (SIB1) of the RMSI is "11000000", indicating the first and second SSB groups. The bitmap within the group is "11000000", indicating the first two SSBs in the first and second groups. Therefore, a total of 2x2=4 SSBs are transmitted, assuming they are numbered SSB0, SSB1, SSB8, and SSB9. At this time, the network needs to ensure that the ssb-PositionsInBurst indication in the signaling sent by the primary cell for the configuration of the primary / secondary cell A (e.g., ServingCellConfigCommon) is also SSB0, SSB1, SSB8, and SSB9. The terminal device establishes an association between SSB and RO based on SSB0, SSB1, SSB8 and SSB9, and performs rate matching based on SSB0, SSB1, SSB8 and SSB9.

[0103] This disclosure also provides a network-side device. Since the principle of the network-side device in solving the problem is similar to the signal processing method in this disclosure, the implementation of the network-side device can refer to the implementation of the method, and the repeated parts will not be described again.

[0104] Referring to Figure 4, this embodiment of the present disclosure also provides a network-side device 400, which includes: a transmitting module 401, configured to transmit first information via Residual Minimum System Information (RMSI); and / or, transmit second information via Radio Resource Control (RRC) signaling;

[0105] Wherein, the SSB-related information indicated by the first indication information and the SSB-related information indicated by the second indication information are at least partially consistent.
