DATA PROCESSING METHOD AND APPARATUS

TECHNICAL FIELD

Embodiments of the present disclosure relate to the field of communication technology, and in particular, to a method and apparatus for processing data.

BACKGROUND

In an unlicensed spectrum, due to limitation of the power spectrum density (PSD), a base station often needs to perform beam repetition to improve the coverage of a synchronization signal block.

In a new radio (NR) release 16 (R16) unlicensed spectrum, beam repetition information of a synchronization signal block is notified to a terminal device through a quasi co-location (QCL) parameter Q of a synchronization signal block. For example, the QCL parameter of a synchronization signal block is Q, the terminal device obtains a value of Q through a signaling transmitted by a base station, and if candidate synchronization signal block indexes of two synchronization signal blocks mod Q (divided by Q to take the remainders) have the same value, the two synchronization signal blocks are QCL, or are beam repeated, or have the same synchronization signal block index (also called beam index). The value of Q can be indicated in an information element (IE) ssbPositionQCL-Relationship, or indicated through bit(s) or code point(s) in a master information block (MIB).

In a high frequency spectrum, in order to support more beams for coverage, it is often needed to use more beams in an initial access stage. More beams would correspond to more synchronization signal blocks. When there are more beams, the largest synchronization signal block index is relatively large, correspondingly, the largest value of Q is relatively large, so that there are more optional values of Q, and potential signaling overhead for indicating the value of Q is relatively high. How to reduce signaling overhead when there are more beams is an urgent problem to be resolved.

DESCRIPTION OF EMBODIMENTS

In order to make purposes, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are a part of embodiments of the present disclosure, rather than all of embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without paying creative effort shall fall within the protection scope of the present disclosure.

For ease of understanding, the concepts involved in the present disclosure are explained first.

Terminal device: it could be a device that includes wireless transceiving functions and can cooperate with a network device to provide communication services for users. Specifically, the terminal device can refer to a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user apparatus. For example, the terminal device could be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or in a network after 5G.

Network device: it could be a device used to communicate with a terminal device. For example, it could be a base station (Base Transceiver Station, BTS) in a global system for mobile communication (GSM) or in a code division multiple access (CDMA) system, or a base station (NodeB, NB) in a wideband code division multiple access (WCDMA) system, or an evolutional base station (Evolutional NodeB, eNB or eNodeB) in an LTE system, or, the network device could be a relay station, an access point, a vehicle-mounted device, a wearable device, or a network side device in a future 5G network or in a network after 5G, or a network device in a future evolutional public land mobile network (PLMN) network.

The network device in the embodiments of the present disclosure may also refer to a radio access network (RAN) device. The RAN device, which is connected to a terminal device, is used to receive data from the terminal device and send the data to a core network device. The RAN device corresponds to different devices in different communication systems. For example, it corresponds a base station and a base station controller in a 2G system, corresponds to a base station and a radio network controller (RNC) in a 3G system, corresponds to an evolutional base station (Evolutional Node B, eNB) in a 4G system, and corresponds to, for example, an access network device (e.g., gNB, centralized unit CU, distributed unit DU) in a 5G system such as NR.

With reference to FIG. 1, the scenario, in which the method of the present disclosure is applied, is illustrated as follows.

FIG. 1 is a schematic diagram of an application scenario provided by an embodiment of the present disclosure. As shown in FIG. 1, the application scenario includes a network device 101 and a terminal device 102, and the network device 101 can communicate with the terminal device 102 wirelessly.

The network includes the network device 101 and the terminal device 102, and can also be called a non-terrestrial network (NTN), where the NTN is a communication network between the terminal device and a satellite (also called network device).

It is understandable that the technical solutions provided by the embodiments of the present disclosure, can be applied in communication technology of NR, where the NR is a new generation of wireless access network technology, and can be applied in a future evolutional network, such as the future 5th generation mobile communication (5G) system. The technical solutions in the embodiments of the present disclosure can also be applied to other wireless communication networks such as the wireless fidelity (WIFI) or the long term evolution (LTE) or the like, and corresponding names can also be replaced by names of the corresponding functions in other wireless communication networks.

The network architectures and the application scenarios described in the embodiments of the present disclosure are for the sake of explaining the technical solutions in the embodiments of the present disclosure more clearly, rather than limitations to the technical solutions in the embodiments. Those of ordinary skills in the art know that, with the evolution of network architectures and the emergence of new application scenarios, the technical solutions in the embodiments of the present disclosure are also used for similar problems.

In Release 15 (R15) of NR, the synchronization signal and the broadcast channel form a synchronization signal block, for introducing the function of beam sweeping.

Through the primary synchronization signal (PSS) and the secondary synchronization signal (SSS), UE obtains time-frequency synchronization of a cell and a physical layer cell ID of the cell. This process is generally called cell search.

The PSS, the SSS, and the physical broadcast channel (PBCH) form an SS/PBCH block (synchronization signal block).

Each synchronization signal block has a time domain location predetermined. The time domain location can also be called a candidate synchronization signal block. Multiple synchronization signal blocks form an SS-burst (synchronization signal burst). Multiple synchronization signal blocks form a synchronization signal burst. Multiple synchronization signal bursts form an SS-burst-set (synchronization signal burst set). The Lmax time domain positions of the synchronization signal block are fixed within a window of 5 ms. The Lmax time domain position indexes of the synchronization signal block are in a consecutive order from 0 to Lmax−1. Therefore, the transmitting time of a synchronization signal block in the window of 5 ms is fixed, and the indexes are also fixed.

Generally speaking, a base station transmits a synchronization signal block through beam sweeping. That is, the base station transmits the synchronization signal block through different beams at different time domain positions. Accordingly, UE can measure different beams and sense at which beam the strongest signal is received.

In a licensed spectrum of NR (NR licensed spectrum, also called unshared spectrum access), a UE obtains timing information within 5 ms by acquiring candidate synchronization signal block indexes. In a licensed spectrum, the candidate synchronization signal block indexes are related to the Lmax candidate positions of the synchronization signal block. When Lmax=4, the lower two bits (2 LSBs) of a candidate synchronization signal block index are carried in a PBCH-DMRS (demodulation reference signal of PBCH); when Lmax>4, the lower three bits (3 LSBs) of a candidate synchronization signal block index are carried in the PBCH-DMRS; when Lmax=64, the higher 3 bits (3 MSBs) of a candidate synchronization signal block index are in PBCH payload or carried in an MIB. In this case, the number of candidate synchronization signal block indexes is equal to the number of synchronization signal block indexes.

In an unlicensed spectrum of NR (NR unlicensed spectrum, NR-U, also called shared spectrum access), a UE obtains timing information within 5 ms by acquiring candidate synchronization signal block indexes. In an unlicensed spectrum, the candidate synchronization signal blocks within a half frame are numbered in the order from 0 to Lmax-1. When the subcarrier spacing of the synchronization signal blocks is 15 kHz, Lmax=10; when the subcarrier spacing of the synchronization signal blocks is 30 kHz, Lmax=20. The UE determines, through the index of a PBCH DMRS sequence (one-to-one mapping), the 3 LSB bits of a candidate synchronization signal block index within a half frame. For Lmax=10, UE determines, through the bit ā_Ā+7of PBCH payload, 1 MSB bit of a candidate synchronization signal block index within a half frame. For Lmax=20, UE determines, through the bits ā_Ā+6, ā_Ā+7of PBCH payload, 2 MSB bits of a candidate synchronization signal block index within a half frame.

In an unlicensed spectrum of NR, a candidate synchronization signal block index is different with a synchronization signal block index. The candidate synchronization signal block index represents an index of a synchronization signal block in a candidate position, while the synchronization signal block index represents a beam index of a synchronization block. In this case, the number of candidate synchronization signal block indexes may be greater than the number of synchronization signal block indexes. The synchronization signal block can be a synchronization signal block within a window (such as a discovery burst transmission window), so as to reduce the number of candidate synchronization signal block indexes and reduce UE complexity.

In an unlicensed spectrum, before transmitting a synchronization signal block, a base station needs to conduct listen before talk (LBT) or conduct channel access assessment (CAA). The base station can transmit a synchronization block once it detects that the channel is available. It is because of the LBT that a window needs to be predefined, where there are more candidate positions (or indexes) for a synchronization signal block within the window than the number of synchronization signal blocks that need to be transmitted actually. When detecting that a channel is busy, the base station can continue listening until a channel is detected to be available, and then transmits a synchronization signal block in the subsequent candidate positions for the synchronization signal block.

On the other hand, in an unlicensed spectrum, due to limited power spectrum density (PSD), it is difficult to use more and narrower beams to meet coverage requirement, so the base station often needs to perform beam repetition to improve the coverage of synchronization signal blocks. Generally, the base station can inform UE beam repetition information of synchronization signal blocks, so that the UE knows which measurement values of the synchronization signal blocks can be averaged when measuring (the measurement values of the synchronization signal blocks transmitted by the same beam can be averaged). The base station can also have more PDCCH transmitting occasions associated with the synchronization signal blocks, since the UE needs to listen to multiple PDCCHs associated with multiple synchronization signal blocks transmitted by the same beam.

In R16 NR-U, beam repetition information of a synchronization signal block is notified to UE through a QCL parameter of the synchronization signal block. For example, the QCL relationship parameter of the synchronization signal block is Q, and the UE obtains the value of Q through a signaling of a base station. If candidate synchronization signal block indexes of two synchronization signal blocks mod Q (divided by Q to take the remainders) have the same value, the two synchronization signal blocks are QCL, or are beam repeated, or have the same synchronization signal block index (also called beam index).

In general, the value of the candidate synchronization signal block index mod Q is called a synchronization signal block index (also called a beam index). The largest synchronization signal block index is equal to the largest value of Q. The optional values of Q are integer factors of the largest value of Q. For example, in an unlicensed spectrum of Release 16 NR, the largest value of Q is 8, and the optional values of Q are 8, 4, 2, 1. In Release 16 NR-U, a master information block (MIB) uses only 2 bits or 4 code points to indicate the optional values of Q. Generally speaking, when the number of bits is x, the number of code points (the coded possibility) is 2 to the power of x.

In a high frequency band, such as a spectrum of 52.6 GHz-71 GHz, there are high frequency band characteristics, and the unlicensed spectrum access technology can be adopted. Due to the fact of high frequency band, more beams are needed to achieve better coverage. Generally speaking, a base station can realize an initial access with more beams by using more beams to transmit synchronization signal blocks, so that the UE can receive at least one synchronization signal block transmitted by a beam at different directions of a cell. When there are more beams, the largest synchronization block index is relatively large, and the corresponding largest value of Q is relatively large. For example, when the largest value of Q is 64, there are more optional values of Q, and the signaling overhead for indicating potential values of Q is relatively high. How to reduce the signaling overhead when there are more beams is an urgent problem to be solved.

To solve the above problem, the embodiments of the present disclosure provide a method for processing data, so as to determine an optional value of Q when there are more beams. The technical solutions of the present disclosure are illustrated below with reference to the drawings.

FIG. 2 is a flow diagram of a method for processing data provided in an embodiment of the present disclosure. The method is applied to a terminal device. As shown in FIG. 2, the method may include as follows.

S21, obtain a signaling;

S22, obtain a value of a quasi co-location parameter Q based on the signaling.

A terminal device can obtain a value of Q through a signaling. After obtaining the value of Q, the terminal device may judge whether two synchronization signal blocks have a quasi co-location relationship. For example, based on the candidate synchronization signal block indexes of the synchronization signal blocks mod the value of Q (that is, divided by the value of Q to take the remainder), if the candidate synchronization signal block indexes of two synchronization signal blocks mod the value of Q have the same value, the two synchronization signal blocks have a quasi co-location relationship. Alternatively, it is possible to determine a synchronization signal block index based on the value of Q. For example, based on the candidate synchronization signal block index mod the value of Q (that is, divided by the value of Q to take the remainder), the result obtained is a synchronization signal block index. Alternatively, beam repetition information of a synchronous signal block may be obtained based on the value of Q. For example, it is possible to make the candidate synchronization signal block indexes mod the value of Q (that is, divided by the value of Q to take the remainder), if the candidate synchronization signal block indexes of two synchronization signal blocks mod the value of Q have the same value, the two synchronization signal blocks are beam repeated.

In a possible implementation, the terminal device may obtain, in a value set of Q, the value of Q based on the signaling transmitted by a network device.

In a possible implementation, there are four optional values of Q, and by determining the four optional values of Q, the signaling overhead can be reduced.

In a possible implementation, it is possible to obtain, in a value set of Q, the value of Q based on a bit or a code point in the signaling. For example, the terminal device may obtain 2 bits from the signaling transmitted by a network device, and determine the value of Q based on the 2 bits, where the 2 bits may correspond to 4 optional values of Q. Thus, the signaling overhead by the 2 bits in the signaling can be reduced.

In a possible implementation, the signaling is a master information block (MIB). The terminal device may obtain the bit(s) or code point(s) from the MIB, and obtain, in a value set of Q, the value of Q based on the bit(s). The terminal device may quickly obtain the value of Q of a serving cell through the MIB.

In a possible implementation, the signaling is a system information block (SIB). The terminal device may obtain the value of Q of a neighbor cell through the SIB, which is beneficial for cell reselection.

In a possible implementation, the signaling is radio resource control (RRC) information. The terminal device may obtain the value of Q of a target cell when switching through RRC information, which is beneficial for switching.

The embodiments of the present disclosure provide a method for processing data, which is applied to a terminal device and includes: firstly obtaining a signaling from a network device, and then obtaining a value of a quasi co-location relationship parameter Q based on the signaling. By obtaining the value of Q, it is possible to learn whether two synchronization signal blocks have a quasi co-location relationship, or obtain a synchronization signal block index, or obtain beam repetition information of a synchronization signal block. In the embodiments of the present disclosure, it is possible to obtain a value of Q through a signaling transmitted by a network device, thus solving the problem of signaling overhead when there are more beams.

Technical solutions in the present disclosure are illustrated in detail as follows, combining with specific embodiments.

After obtaining a signaling from a network device, a terminal device needs to obtain a value of Q from a value set of Q based on the signaling. Where the value of Q belongs to the value set of Q. Alternatively, elements in the value set of Q are candidate values of Q. The value set of Q includes a plurality of different elements. The largest value of Q is a possible largest value of Q predefined. The largest value of Q is generally the largest synchronization signal block index, or the largest number of beams for synchronization signal blocks. In general, the largest value of the elements in the value set of Q is equal to the largest value of Q. In the following, the value ranges of the elements in the value set of Q in different cases will be introduced in the first place.

In a possible implementation, elements in the value set of Q are from all factors of the largest value of Q. Here, factor B of integer A indicates that the integer A is divisible by B. The reason why the elements in the value set of Q are from all factors of the largest value of Q is that, if the elements in the value set of Q are all factors of the largest value of Q, after candidate synchronization signal block positions (indexes) are divided into multiple groups based on the largest value of Q, the synchronization signal block indexes of the same position in each group may be the same.

In a possible implementation, when the largest value of Q is M, optional values of Q include: M/8, M/4, M/2, or M, where a value of M is any one of 16, 32, or 64.

In a possible implementation, when the largest value of Q is 16, elements in the value set of Q are from 1, 2, 4, 8, 16, that is, optional values of Q are from 1, 2, 4, 8, 16. In the present disclosure, elements in the value set of Q are from a, b, c, that is, optional values of Q are selected from a, b, c, representing that the elements in the value set of Q can be selected from the set {a, b, c}.

In a possible implementation, when the largest value of Q is 32, elements in the value set of Q are from 1, 2, 4, 8, 16, 32, that is, optional values of Q are selected from 1, 2, 4, 8, 16, 32.

In a possible implementation, when the largest value of Q is 64, elements in the value set of Q are from 1, 2, 4, 8, 16, 32, 64, that is, optional values of Q are selected from 1, 2, 4, 8, 16, 32, 64.

In a possible implementation, the largest value of Q can be any one of 12, 18, 20, 24, 30, 36, 40, 48, 54 or 60.

In a possible implementation, when the largest value of Q is 12, elements in the value set of Q are from 1, 2, 3, 4, 6, 12, that is, optional values of Q are selected from 1, 2, 3, 4, 6, 12.

In a possible implementation, when the largest value of Q is 18, elements in the value set of Q are from 1, 2, 3, 6, 9, 18, that is, optional values of Q are selected from 1, 2, 3, 6, 9, 18.

In a possible implementation, when the largest value of Q is 20, elements in the value set of Q are from 1, 2, 4, 5, 10, 20, that is, optional values of Q are selected from 1, 2, 4, 5, 10, 20.

In a possible implementation, when the largest value of Q is 24, elements in the value set of Q are from 1, 2, 3, 4, 6, 8, 12, 24, that is, optional values of Q are selected from 1, 2, 3, 4, 6, 8, 12, 24.

In a possible implementation, when the largest value of Q is 30, elements in the value set of Q are from 1, 2, 3, 5, 6, 10, 15, 30, that is, optional values of Q are selected from 1, 2, 3, 5, 6, 10, 15, 30.

In a possible implementation, when the largest value of Q is 36, elements in the value set of Q are from 1, 2, 3, 4, 6, 9, 12, 18, 36, that is, optional values of Q are selected from 1, 2, 3, 4, 6, 9, 12, 18, 36.

In a possible implementation, when the largest value of Q is 40, elements in the value set of Q are from 1, 2, 4, 5, 10, 20, 40, that is, optional values of Q are selected from 1, 2, 4, 5, 10, 20, 40.

In a possible implementation, when the largest value of Q is 48, elements in the value set of Q are from 1, 2, 3, 4, 6, 8, 12, 16, 24, 48, that is, optional values of Q are selected from 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.

In a possible implementation, when the largest value of Q is 54, elements in the value set of Q are from 1, 2, 3, 6, 9, 18, 27, 54, that is, optional values of Q are selected from 1, 2, 3, 6, 9, 18, 27, 54.

In a possible implementation, when the largest value of Q is 60, elements in the value set of Q are from 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60, that is, optional values of Q are selected from 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.

The value of Q belongs to a value set of Q. Elements in the value set of Q are candidate values of Q. Therefore, after determining the value set of Q, it is possible to obtain in the value set of Q the value of Q. Description is made with reference to FIG. 3 in the following.

FIG. 3 is a flow diagram of a method for obtaining a value of Q provided by an embodiment of the present disclosure, as shown in FIG. 3, the method includes as follows.

S31, obtain a bit or a code point based on a signaling.

The signaling is a signaling transmitted by a network device to a terminal device. It is possible to obtain a bit or a code point through the signaling, and determine the value of Q based on the bits or the code point.

S32, obtain, in the value set of Q, the value of Q based on the bit or the code point.

It is possible to obtain, in the value set of Q, the value of Q based on the bit. For example, the terminal device obtains 2 bits or 4 code points and determines the corresponding 4 optional values of Q based on the 2 bits or the 4 code points.

After determining the value range of elements in the value set of Q, it is possible to further determine the value set of Q. In this way, the range of optional values of Q can be narrowed down and the signaling overhead can be saved. Determination of the value set of Q is described as follows.

In a possible implementation, elements in the value set of Q include four largest factors of the largest value of Q, where:

when the largest value of Q is 16, or when elements in the value set of Q are from 1, 2, 4, 8, 16, the elements in the value set of Q include 2, 4, 8, 16;

when the largest value of Q is 32, or when elements in the value set of Q are from 1, 2, 4, 8, 16, 32, the elements in the value set of Q include 4, 8, 16, 32;

when the largest value of Q is 64, or when elements in the value set of Q are from 1, 2, 4, 8, 16, 32, 64, the elements in the value set of Q include 8, 16, 32, 64;

when the largest value of Q is 12, or when elements in the value set of Q are from 1, 2, 3, 4, 6, 12, the elements in the value set of Q include 3, 4, 6, 12;

when the largest value of Q is 18, or when elements in the value set of Q are from 1, 2, 3, 6, 9, 18, the elements in the value set of Q include 3, 6, 9, 18;

when the largest value of Q is 20, or when elements in the value set of Q are from 1, 2, 4, 5, 10, 20, the elements in the value set of Q include 4, 5, 10, 20;

when the largest value of Q is 24, or when elements in the value set of Q are from 1, 2, 3, 4, 6, 8, 12, 24, the elements in the value set of Q include 6, 8, 12, 24;

when the largest value of Q is 30, or when elements in the value set of Q are from 1, 2, 3, 5, 6, 10, 15, 30, the elements in the value set of Q include 6, 10, 15, 30;

when the largest value of Q is 36, or when elements in the value set of Q are from 1, 2, 3, 4, 6, 9, 12, 18, 36, the elements in the value set of Q include 9, 12, 18, 36;

when the largest value of Q is 40, or when elements in the value set of Q are from 1, 2, 4, 5, 10, 20, 40, the elements in the value set of Q include 5, 10, 20, 40;

when the largest value of Q is 48, or when elements in the value set of Q are from 1, 2, 3, 4, 6, 8, 12, 16, 24, 48, the elements in the value set of Q include 12, 16, 24, 48;

when the largest value of Q is 54, or when elements in the value set of Q are from 1, 2, 3, 6, 9, 18, 27, 54, the elements in the value set of Q include 9, 18, 27, 54;

when the largest value of Q is 60, or when elements in the value set of Q are from 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60, the elements in the value set of Q include 15, 20, 30, 60.

Since a larger value of Q represents a smaller number of repeated beams, it is more suitable for a high-frequency environment by selecting the four largest factors of the largest value of Q, and a larger value of Q can reduce complexity of a terminal device. For example, it can reduce the number of type0-physical downlink control channels (Type0-PDCCH) to be monitored, since UE needs to monitor Type0-PDCCH5 associated with synchronization signal blocks having a QCL relationship.

It is possible to determine the elements in the value set of Q in other ways, in addition to selecting 4 largest factors of the largest value of Q.

In a possible implementation, the elements in the value set of Q at least include 1, the largest value of Q, or, first two or three largest factors of the largest value of Q. Where the elements in the value set of Q may include any one of the three of 1, the largest Q value, and the first two or three largest factors of the largest value of Q; the elements in the value set of Q may also include any two of the three of 1, the largest Q value, and the first two or three largest factors of the largest Q value; or, the elements in the value set of Q may include 1, the largest Q value, and the first two or three largest factors of the largest value of Q.

In a possible implementation, the elements in the value set of Q may at least include the largest value of Q. The largest value of Q represents the largest number of beams that a network device (base station) can transmit. The largest value of Q indicates the smallest number of repeated beams, which is more suitable for a high-frequency environment. Moreover, a larger value of Q can reduce complexity of a terminal device, for example, the number of Type0-PDCCHs that need to be monitored can be reduced.

In a possible implementation, the elements in the value set of Q may at least include 1. The value of Q being 1 represents that all beams are repeated, which is suitable for a scenario of omnidirectional transmission, i.e., a single beam.

In a possible implementation, the elements in the value set of Q may at least include the first two or three largest factors of the largest value of Q. In this way, it can be ensured that optional values of Q are large enough, while making it free to select other types of values of Q.

In a possible implementation, the elements in the value set of Q at least include 1, the largest value of Q, or, the first two or three largest factors of the largest value of Q, where:

when the largest value of Q is 16, or when elements in the value set of Q are from 1, 2, 4, 8, 16, the elements in the value set of Q include 1, 4, 8, 16;

when the largest value of Q is 32, or when elements in the value set of Q are from 1, 2, 4, 8, 16, 32, the elements in the value set of Q include 1, 4, 16, 32, or, 1, 8, 16, 32;
