Description

Technical Field

[0001] (Cross - reference to Related Applications) This application claims the priority of Chinese Patent Application No. 202210102661.X, filed in China on January 27, 2022, and all the contents of the same application are incorporated herein by reference.

[0002] This application belongs to the field of communication technology, and specifically relates to a method for receiving a synchronization signal block, a method for transmitting a synchronization signal block, and related devices.

Background Art

[0003] With the development of communication technology, reduced - capability (RedCap) terminals have emerged in communication systems. For RedCap terminals, since the supported bandwidth is below the bandwidth capability of general terminals, the bandwidth part (Bandwidth Part, BWP) configured by network - side devices for general terminals may exceed the capabilities of RedCap terminals. The network - side device can configure an additional first BWP for the RedCap terminal to make the bandwidth of this first BWP within the capability range of the RedCap UE. Since this first BWP does not include the cell - defining synchronization signal block (Cell Defining Synchronization Signal and PBCH block, CD - SSB), considering not monitoring paging on this first BWP, it is necessary to switch to a second BWP including the CD - SSB to monitor paging. Thus, the system signaling overhead is relatively large, causing waste of resources.

For the purposes of this explanation, only base stations in NR systems are given as examples in the embodiments of this application, but this does not limit the specific types of base stations.

[0023] To facilitate understanding, the following describes some aspects of the embodiments of this application.

[0024] 1. Transmission of the synchronization signal block.

[0025] In the design of an NR system, an NR base station needs to transmit SSBs so that terminals can perform synchronization, acquire system information, and perform measurement and evaluation. A single SSB consists of two parts: the NR-Synchronization Signal (SS) and the NR-Physical Broadcast Channel (PBCH). Here, the NR-SS is divided into two parts: the NR-Primary Synchronization Signal (PSS) and the NR-Secondary Synchronization Signal (SSS). The NR-PBCH is used to acquire the Master Information Block (MIB). The MIB also carries Downlink (DL) baseband parameter (numerology) information, which is used to indicate whether the SSB's numerology matches the Remaining Minimum System Information (RMSI), msg2 / 4 used for initial access, and the Open System Internetconnect (OSI) numerology for broadcasts.

[0026] Multiple SSBs constitute a single SS burst set. The maximum number of SSBs included in a single SS carrier burst set is related to the carrier frequency used by the network. If the frequency is less than 3GHz, a single SS burst set can contain a maximum of L=4 SSBs. If the carrier frequency range is from 3GHz to 6GHz, a single SS burst set can contain a maximum of L=8 SSBs. When the carrier frequency range is 6GHz or higher, a single SS burst set can contain a maximum of L=64 SSBs.

[0027] Regardless of the number of SSBs included in a single SS burst set, each of these SSBs must complete transmission within a single 5ms transmission window.

[0028] NR supports different numerologies, and SSB symbols and other symbols (e.g., symbols for uplink control, downlink control, guard intervals, and data transmission) may employ different numerologies and be multiplexed (the other symbols mentioned later refer to other symbols when they are multiplexed with SSB). In different numerologies, the possible positions of SSB within a slot differ, and the position of the slot where SSB is located may also differ within the 5ms transmit window. If NR above 6GHz supports subcarrier intervals of 60 / 120 / 240kHz, and NR below 6GHz supports subcarrier intervals of 15 / 30 / 60kHz, then SSB can be transmitted when the subcarrier interval is 15 / 30 / 120 / 240kHz. When the subcarrier interval is 15 / 30 / 60 / 120kHz, other symbols can be transmitted, but when the subcarrier interval is 240kHz, it cannot be used for data transmission. Regardless of the SSB's numerology, the numerology of the RMSI control resource set (CORESET) must match the RMSI's numerology.

[0029] The transmission locations for SSB as defined in the NR protocol are as follows:

[0030] In a single half-frame, the symbol index of the first OFDM symbol in the SSB Block is related to the subcarrier spacing of the SSB, where the orthogonal frequency division multiplex (OFDM) symbol with number 0 is the first OFDM symbol in the first slot in a 5ms half-frame.

[0031] In Case 1, with a 15kHz subcarrier spacing, the symbol number of the first OFDM symbol transmitting SSB is {2, 8} + 14*n. When the carrier frequency is 3GHz or less, n=0,1. When the carrier frequency is greater than 3GHz and 6GHz or less, n=0,1,2,3.

[0032] In Case 2, with a 30 kHz subcarrier spacing, the symbol number of the first OFDM symbol transmitting SSB is {4, 8, 16, 20} + 28*n. When the carrier frequency is 3 GHz or less, n=0. When the carrier frequency is greater than 3 GHz and 6 GHz or less, n=0,1.

[0033] In Case 3, if the subcarrier spacing is 30 kHz, the symbol number of the first OFDM symbol transmitting SSB is {2,8}+14*n, and the carrier frequency is 3 GHz or less, then n=0,1. If the carrier frequency is greater than 3 GHz and 6 GHz or less, then n=0,1,2,3.

[0034] In Case 4, with a 120 kHz subcarrier spacing, the symbol number of the first OFDM symbol transmitting SSB is {4, 8, 16, 20} + 28*n. When the carrier frequency is greater than 6 GHz, n = 0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

[0035] 2. Sending and receiving system information The transmission of system information is related to the transmission of a synchronization signal block, and in the PBCH of the synchronization signal block, it specifies the monitoring parameters of the system information physical downlink control channel (PDCCH) that schedules SIB-1. One of the monitoring occasions and SSB association methods for this PDCCH is as follows: The PDCCH monitoring occasion of the scheduling SIB-1 associated with each SSB is the PDCCH monitoring occasion of two consecutive slots. The UE determines the PDCCH monitoring occasion of the associated scheduling SIB-1 based on the SSB index and performs monitoring of the PDCCH. A pseudo-collocation relationship is satisfied between this PDCCH and the associated synchronization signal block. Here, SIB stands for System Information Block.

[0036] 3. Sending via paging channels.

[0037] The UE determines paging occasions (POs) based on the terminal identifier (UE-ID) and the period of discontinuous reception (DRX) during idle states, and a single PO contains multiple paging PDCCH monitoring occasions. There is a one-to-one correspondence in chronological order between the N PDCCH occasions within this PO and the N SSBs transmitted from the network-side equipment. These N SSBs are the N SSBs of transmissions configured by the network through upper-layer signaling. The nth paging PDCCH monitoring occasion, corresponding to the nth (1≦n≦N) SSB, satisfies a quasi-co-located relationship (QCL).

[0038] In other words, the paging signal is also transmitted using a beam scanning method, and the beam transmitted by the paging PDCCH and paging PDSCH is the same as the beam used for the corresponding SSB transmission.

[0039] Four, Redcap UE.

[0040] For RedCap UEs, the supported bandwidth is less than or equal to the bandwidth capacity of a typical UE. Therefore, the BWP bandwidth configured by network-side equipment for a typical UE may exceed the capacity of the RedCap terminal. The network can bring this BWP bandwidth within the RedCap UE's capabilities by configuring an additional BWP on the RedCap terminal.

[0041] Furthermore, because RedCap UEs have fewer receiving antennas than typical UEs, their receiving performance is lower, which can lead to network equipment using greater overhead and resources to transmit RedCap UEs. Thus, even if the bandwidth of the BWP configured by the network equipment is within the capabilities of the RedCap UE, if the network uses the same BWP to transmit both typical UEs and RedCap UEs, the load on this BWP may become too great, potentially causing congestion in general terminal transmissions. Therefore, the current Work Item has reached the following conclusion:

[0042] The network-side equipment can configure a separate initial DL BWP (i.e., the first initial BWP) for the RedCap terminal, and if this first initial BWP does not include the CD-SSB (i.e., the second SSB) and the entire control resource set (CORESET#0) numbered 0, If a search space for random access is configured on this first initial BWP, i.e., a Type 1 Common Search Space (Type 1 CSS) is configured, and no search space related to paging is configured, then the SSB, CORESET#0, and SIB do not need to be included on this first initial BWP.

[0043] RedCap UEs in Radio Resource Control IDLE (RRC_IDLE) and RRC Inactive (RRC_INACTIVE) states must monitor paging messages in the initial BWP associated with the second SSB (i.e., the second initial BWP). RedCap UEs in RRC_IDLE and RRC_INACTIVE states do not further consider monitoring paging in the first initial BWP associated with the first SSB. Here, the first SSB may be understood as a Non-Cell Defining SSB (NCD-SSB).

[0044] For a downlink activation BWP (hereinafter referred to as the first BWP) configured on a RedCap UE with RRC connection (RRC_CONNECTED), if it does not include the second SSB and the entire CORESET#0, A RedCap UE that only supports the forced 6-1 characteristic (FG 6-1) and not the optional 6-1a characteristic (FG 6-1a) is expected to include a first SSB for the serving cell but not CORESET#0 / SIB. The first BWP mentioned above may be the first initial BWP for an RRC_IDLE / INACTIVE / CONNECTED UE, or it may be the activated BWP of any UE in the RRC_CONNECTED state.

[0045] Selectively, the period of the first SSB does not require the same configuration as the second SSB, and the period of the first SSB should be greater than or equal to the period of the second SSB.

[0046] Currently, there is no defined method for the configuration signaling and network of the first SSB to provide first SSB availability to RedCap UEs with RRC_IDLE and RRC_INACTIVE.

[0047] In the following sections, the method for receiving a synchronous signal block according to the embodiment of this application will be described in detail with reference to several embodiments and their application scenarios, while referring to the drawings.

[0048] Referring to Figure 2, an embodiment of this application provides a method for receiving a synchronous signal block, and this method is The terminal performs step 201, which involves obtaining first information of the first synchronization signal block SSB from the network-side device, The terminal includes step 202 of receiving the first SSB based on the first information, Here, the first SSB is a non-cell-defined SSB, and the first information includes at least one of the following: frequency domain start position, subcarrier spacing (SCS), SSB index, SSB period, SSB transmit power, and physical cell identifier (PCI).

[0049] In the embodiments of this application, the terminal may be a RedCap terminal. The first information may be understood as some configuration information of the first SSB. If the first information does not include at least one of the parameters of the first SSB, such as SCS, SSB index, SSB period, SSB transmit power, and PCI, the terminal may default that this at least one parameter is the same as the corresponding parameter in the second SSB. For example, if the first information includes the frequency domain start position, subcarrier spacing (SCS), SSB index, SSB period, and SSB transmit power, the terminal may assume, determine, or consider that the PCI of the first SSB is the same as the PCI of the second SSB.

[0050] The embodiments of this application, by determining the configuration of the first SSB, can support connected RedCap terminals using the first SSB to perform radio resource management (RRM) and radio link monitoring (RLM), and can also support idle / inactive RedCap terminals using the first SSB to perform channel measurement and cell reselection. In this way, RedCap terminals do not need to switch BWPs, reducing the operational complexity of RedCap terminals and lowering signaling and resource overhead.

[0051] Selectively, in some embodiments, the frequency domain start position is comprised of an absolute frequency domain position or a frequency offset parameter.

[0052] For example, in some embodiments, the absolute frequency domain position may be defined by the parameter ssbFrequency or absoluteFrequencySSB. This absolute frequency domain position may also be called the Absolute Radio-Frequency Channel Number (ARFCN). It should be understood that the above frequency offset parameter may be used to indicate an offset value. For example, the frequency domain start position may be determined based on this offset value and the frequency offset reference position agreed upon by the protocol.

[0053] Selectively, in some embodiments, the frequency domain start position is determined based on a frequency offset reference position, and the frequency offset reference position is The system includes at least one of the following: the start position of the first bandwidth portion BWP, the end position of the first BWP, the start position of the second BWP, the end position of the second BWP, the start position of the second SSB, the end position of the second SSB, the start position of the control resource set numbered 0, the end position of the control resource set numbered 0, the start position of the first control resource set, the end position of the first control resource set, reference point A, and the start position and end position of the serving cell. Here, the first control resource set is the control resource set of the smallest index or the control resource set of the largest index included on the first BWP, the first BWP is at least one of the initial BWP that the terminal is independent of the second BWP and the BWP that the terminal has activated, the second BWP is a BWP that includes the second SSB, and the second SSB is a cell definition SSB.

[0054] In some embodiments, the first control resource set is Common search space CSS for Type 1, CSS of type 2 or type 2A, It is related to at least one of the following CSS types: Type 0 or Type 0A.

[0055] It should be understood that, in the embodiments of this application, the first BWP may be understood as the first initial BWP for an RRC_IDLE, INACTIVE, or CONNECTED terminal, or as the activated BWP of one of the terminals in the RRC_CONNECTED state.

[0056] Selectively, the above SSB index may be composed of the parameters SSB-Index and / or ssb-PositionsInBurst.

[0057] In some selective embodiments, the first information is, BWP Common Downlink Signaling (BWP-DownlinkCommon) and BWP-DownlinkDedicated and System Information Block Frequency Information Downlink Signaling (FrequencyInfoDL-SIB), Frequency Info DL (FrequencyInfoDL) and ServingCellConfigCommon and It is included in at least one of the signaling signals, including the ServingCellConfig signaling.

[0058] Selectively, the first signaling that carries the first information is It includes at least one of the following: terminal-specific signaling, cell-specific signaling, and system information.

[0059] Selectively, the configuration information of the first SSB may include the first information and further include the second information. In some embodiments, the second information of the first SSB is carried by system information, a first object, a terminal-specific radio resource control RRC signaling, and an RRC connection release message, among at least one second signaling. Here, the first target is downlink physical layer signaling or layer 1 signaling.

[0060] For example, network-side equipment may transmit the second information of the first SSB via the downlink control information DCI, or it may transmit the second information of the first SSB via the physical downlink shared channel (PDSCH).

[0061] Selectively, the DCI may be a DCI that carries a paging early indication (PEI) or a DCI that schedules paging.

[0062] Selectively, the above PDSCH is a PDSCH scheduled by a DCI that schedules paging.

[0063] Selectively, in some embodiments, when the terminal receives second information carried by the first object and second information carried by the second object, the terminal determines the second information of the first SSB based on the first object and the second object. Here, the second object includes at least one of the system information, terminal-specific RRC signaling, and RRC connection release messages.

[0064] In the embodiments of this application, the second information in the second object may be overwritten using the second information in the first object. For example, if the second information in the first object includes all the parameter configurations of the second information in the second object, the second information in the first object may be directly determined as the second information in the first SSB. If the second information in the first object includes some of the parameter configurations of the second information in the second object, the parameters may be directly updated in the second object based on the second information in the first object.

[0065] For example, if the second information in the first object includes A1, B1, C1, and D, and the second information in the second object includes A2, B2, and C2, then A1, B1, C1, and D may be determined as the second information of the first SSB.

[0066] For example, if the second information in the first object includes A1, B1, and C1, and the second information in the second object includes A2, B2, C2, and E, then A1, B1, C1, and E may be determined as the second information of the first SSB.

[0067] For example, if the second information in the first object includes A1, B1, C1, and D, and the second information in the second object includes A2, B2, C2, and E, then A1, B1, C1, D, and E may be determined as the second information of the first SSB.

[0068] Selectively, in some embodiments, the second information of the first SSB is Available information and, Unavailable information and, Modification information to instruct that at least one of the available and / or unavailable pieces of information in the second piece of information carried by the second signaling received previously be modified, The second information carried by the second signaling received previously includes at least one of the available information and / or unavailable information instructing not to change at least one of them.

[0069] In the embodiments of this application, the available information is The terminal assumes or expects that the network-side device has transmitted the first SSB, A first available duration, the first duration being used to determine the length of the activation time of the second information, The first available reference point, The first reference point is the start time of the activation time of the second information. This may include at least one of the available first reference points used to determine the

[0070] It should be understood that if the available information includes the first available duration, the duration of the activation time of the second information is equal to the duration of the first.

[0071] Selectively, the duration of the activation time for the second piece of information is: The activation time of the second piece of information is comprised of the upper layers, The activation time for the second piece of information is a predetermined or pre-configured fixed time, The activation time of the second piece of information is determined by the target instruction information, The end time of the activation period for the second piece of information is determined by the terminal receiving the next target instruction information, satisfying at least one of the following conditions: Here, the target instruction information is used to indicate the second information.

[0072] The end time of the activation period for the second piece of information is determined by the terminal receiving the next target instruction information. This can be understood as: when one target instruction information is received, the second piece of information carried in this target instruction information is activated immediately until the next target instruction information is received. When one target instruction information is received, the second piece of information carried in this target instruction information is activated according to the start time configured by the upper layer, agreed upon by the protocol, or indicated by the target instruction information, until the next target instruction information is received.

[0073] Selectively, the start time of the activation period for the second piece of information is: A first time, wherein the first time is the time when the target instruction information was received or the start time of the next time unit after the target instruction information was received, The start time of the target SSB period, wherein the target SSB period is the start time of the target SSB period which is the SSB period associated with the received target instruction information, The time position formed by the upper layers, Including one of the first reference points indicated by the target indication information, Here, the target instruction information is used to indicate the second information.

[0074] In the embodiments of this application, the time unit may be a subframe, slot, or symbol, and is not further limited thereto.

[0075] Selectively, in some of these examples, the aforementioned unavailable information is The terminal does not consider or expect that the network-side device will transmit the first SSB, Unavailable second duration, It includes at least one of the following: a second reference point that is unavailable.

[0076] It should be understood that the above change information may be understood as changing available information in the second information carried by the second signaling received last time to unavailable information, or changing unavailable information in the second information carried by the second signaling received last time to available information. For example, the current layer 1 signaling instruction changes "available" to "unavailable" as indicated by the previous layer 1 signaling, or changes "unavailable" to "available" as indicated by the previous layer 1 signaling.

[0077] The information that remains unchanged above may be understood as not changing the available information in the second information carried by the second signaling that was received last time, or not changing the unavailable information in the second information carried by the second signaling that was received last time. For example, the current layer 1 signaling indication remains unchanged from the "available" indication of the previous layer 1 signaling and is still "available," or it remains unchanged from the "unavailable" indication of the previous layer 1 signaling and is still "unavailable."
