Description

Method, device and communication system for receiving and transmitting control information

Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, an apparatus, and a communication system for receiving and transmitting control information.

Background technique

Non-orthogonal multiple access (NOMA) technology is an important technology of the fifth generation (5G) communication system. NOMA is not limited to the use of orthogonal time-frequency resources to distinguish terminal devices, and thus it is possible to multiplex more terminal devices within limited time-frequency resources. The robustness of NOMA to interference between terminal devices makes it easy to combine with grant-free/configured grants, thereby reducing data latency and signaling overhead. These are important for realizing key performance indicators (KPIs) such as high connection density and low latency of 5G communication systems.

Unlike orthogonal multiple access (OMA), which relies on orthogonal time-frequency resources and/or orthogonal codes to multiplex terminal devices, NOMA can use non-orthogonal resources to complex terminal devices. use. These non-orthogonal resources may include, for example, power, interleaving (corresponding to corresponding interleaver interleaver), sequences, codewords, resource mapping, and the like. Different NOMA transmission modes can be constructed based on different features of these non-orthogonal resources and/or combinations of different features.

Example 1

The embodiment of the invention provides a method for transmitting control information. FIG. 5 is a schematic diagram of a method for transmitting control information according to an embodiment of the present invention, showing a situation on the network device side. As shown in FIG. 5, the method includes:

Step 501: The network device determines a multiplexing mode and/or a multiplexing configuration used by the terminal device to perform information transmission or reception;

Step 502: The network device sends the information about the multiplexing mode and/or the multiplexing configuration to the terminal device.

In this embodiment, the multiplexing manner may include, for example, one or more NOMA modes using at least one of the following resources: power, interleaving, sequence, codeword, and resource mapping. However, the present invention is not limited thereto, and other non-orthogonal resources may also be used; in addition, one of the above non-orthogonal resources may be used as one multiplexing mode, or at least two of the above non-orthogonal resources may be used as another A multiplexing method.

The multiplexing configuration (eg, referred to as a NOMA configuration) may include information of at least one of: bit repetition number information, bit interleaving information, symbol interleaving information, bit scrambling sequence information, symbol scrambling sequence information, bit spreading sequence Information, symbol spreading sequence information, codeword information, resource mapping information, modulation information, and code rate information. However, the present invention is not limited thereto, and other information may be used; in addition, one of the above information may be used as one multiplexing configuration, or at least two of the above information may be used as another multiplexing configuration.

Regarding the above multiplexing method and multiplexing configuration, the above description is exemplarily described in the NOMA mode and the NOMA configuration, but the present invention is not limited thereto, and may be, for example, an OMA mode and/or an OMA configuration. The following is a description of the NOMA mode and the NOMA configuration.

Unlike the OMA that distinguishes terminal devices by virtue of time, frequency, orthogonal code/sequence (which may be referred to as orthogonal resources), the NOMA may use other additional dimensions (which may be referred to as non-orthogonal resources) to distinguish the terminal devices.

For example, different end devices may use different interlaces, and/or different sequences, and/or different codewords, and/or different resource mappings and the like. These "interlaces", "sequences", "codewords", "resource mappings", etc. are equivalent to non-orthogonal resources, but have different signatures from each other. For example, the interleaving may include bit-level interleaving and/or symbol-level interleaving; the sequence may be a spreading sequence and/or a scrambling sequence, each of which may be a symbol sequence or a bit sequence; The mapping can be a resource mapping in a sparse manner. A NOMA approach may be based only on a certain feature (eg, based only on interleaving) or on a combination of multiple features (eg, based on both interleaved and sparse resource mapping).

The NOMA approach based on different features may be applicable to different channel conditions and/or application scenarios. For example, the NOMA method based on bit-level interleaving tends to have better block error rate (BLER) performance in low SNR regions, while the NOMA method based on symbol-level spreading sequences tends to be higher in signal-to-noise. Better BLER performance than regions.

Furthermore, even for a given NOMA mode, a better performance gain can be obtained if the NOMA configuration such as sequence length, interleave length, codeword length, resource mapping mode, etc. can be adaptively adjusted. For example, when the synchronization condition is not good, it is more robust to use a relatively long sequence of relatively long sequences. When the number of concurrent users in the system is small, using a shorter sequence can satisfy the performance index and reduce the receiver. The complexity of demodulation and/or decoding.

In this embodiment, the network device may determine the multiplexing mode and/or the multiplexing configuration based on at least one of the following: the current channel condition, the application scenario, and the number of concurrent users; but the present invention is not limited thereto, and It can be other factors.

That is, the network device can select a suitable NOMA mode and/or a corresponding NOMA configuration, and configure related information to the terminal device through signaling, thereby implementing adaptive adjustment of the NOMA mode and implementing NOMA configuration (eg, sequence length). Adaptive adjustment of interleave length, codeword length, resource mapping mode, etc., enables the NOMA mode and configuration to best meet the needs of current transmission.

For example, N types (N ≥ 1) of the NOMA method can be defined in advance. The NOMA mode can be selected and defined based on different criteria, which is not limited by the present invention. For example, a preferred NOMA mode under the use case can be defined for each typical use case. Use cases can be divided and defined by factors such as channel conditions (eg, signal-to-noise ratio conditions or intervals, etc.), and/or application scenarios (eg, mMTC, eMBB, URLLC, etc.), and/or concurrent users (eg, simultaneous) The number of users transmitted, or the number of users using overlapping time-frequency resources for data transmission, etc.

For example, for the nth NOMA mode (0 ≤ n ≤ N-1), a Cn kind of NOMA configuration can be defined. Each of the NOMA configurations may carry at least one of the following information, or information related to the following information (eg, a corresponding index or serial number, etc.), either explicitly or implicitly:

Number of bit repetitions: Determine how the bit sequence is repeated;

Bit interleaving mode: determining how to perform bit-level interleaving of bit sequences in a manner;

Symbol interleaving: determining how to perform symbol-level interleaving of symbol sequences;

Bit scrambling sequence: bit-level scrambling of a bit sequence;

Symbol scrambling sequence: symbol level scrambling of symbol sequences;

Symbol spreading sequence: a single symbol is expanded into a symbol sequence, that is, a single symbol is multiplied by the symbol spreading sequence;

Codeword: directly obtains a symbol vector or symbol sequence based on bits;

Resource mapping mode: decide whether to map to all resource particles or only to some resource particles; when mapping only to some resource particles, decide which resource particles are empty, that is, sparse resource mapping.

Modulation method: including Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), 16 Quadrature Amplitude Modulation (QAM), 64QAM, 256QAM, and many more.

Rate: Determines the code rate of the channel coding.

For the Cn kinds of NOMA configurations and the information carried by each of the NOMA configurations, different NOMA configurations have at least one of the above information different. For example, different NOMA configurations may correspond to symbol spreading sequences of different lengths.

In this embodiment, the information of the multiplexing mode and/or the multiplexing configuration may be carried by semi-static signaling and/or dynamic signaling. For example, the semi-static signaling may include radio resource control (RRC) signaling, and the dynamic signaling may include downlink control information (DCI, in a physical downlink control channel (PDCCH) (Physical Downlink Control Channel). Downlink Control Information).

For example, the network device may send the NOMA mode and the corresponding NOMA configuration to the terminal device through RRC signaling or a PDCCH. In the case that the new NOMA mode and the corresponding NOMA configuration are not received, the terminal device can always use the NOMA mode and the corresponding NOMA configuration; and when the new NOMA mode and the corresponding NOMA configuration are received, the The terminal device can use the new NOMA mode and the corresponding NOMA configuration. Thereby, switching of the NOMA mode and/or the corresponding NOMA configuration can be implemented semi-statically or dynamically.

For another example, the network device may send the NOMA mode and the corresponding multiple NOMA configurations to the terminal device by using RRC signaling, and then use the PDCCH to instruct the terminal device to use one of the multiple NOMA configurations described above. In the case that the new NOMA mode is not received, the terminal device can always use the NOMA mode and the NOMA configuration indicated in the recently received PDCCH; and when the new NOMA mode is received, the terminal device can use the terminal device. The new NOMA mode and the NOMA configuration indicated in the most recently received PDCCH. Thereby, the switching of the NOMA mode can be implemented semi-statically, and the switching of the corresponding NOMA configuration can be dynamically implemented.

It should be noted that the foregoing only describes the signaling of the bearer multiplexing mode and/or the multiplexing configuration, but the present invention is not limited thereto, and may be other signaling and/or channel, for example. In addition, the information of the multiplexing mode and/or the multiplexing configuration (which may be referred to as related information) may be the information itself that characterizes the multiplexing mode and/or the multiplexing configuration, or may represent the multiplexing mode and/or The identifier (or serial number, index) of the multiplexed configuration.

For example, at least two multiplexing modes and/or multiplexing configurations are predetermined (or predefined), and agreement can be reached between the network device and the terminal settings. The network device may select one multiplexing mode and/or multiplexing configuration from the at least two multiplexing modes and/or multiplexing configurations according to various factors, and associate related information (the multiplexing mode and/or multiplexing) The configured information is sent to the terminal device. The related information may include an index of the one multiplexing mode and/or multiplexing configuration in the at least two multiplexing modes and/or multiplexing configurations, but is not limited thereto; and is exemplified below.

It is assumed that N=3 kinds of NOMA modes are defined, respectively, an interleaving based NOMA method (NOMA mode 0, for example, as shown in FIG. 2), and a spreading based NOMA method (NOMA method 1, for example As shown in FIG. 3) and a codeword based based NOMA method (NOMA mode 2, for example, as shown in FIG. 4).

For the three NOMA modes and the corresponding NOMA configurations, they can be defined in advance and stored in the network device and the terminal device respectively, so that the network device and the terminal device reach an agreement. Table 1 exemplarily shows an association relationship between the above NOMA mode and the NOMA configuration;

Table 1

As shown in Table 1, NOMA mode 0 can use R _J different bit repetition times (R _J ≥ 1), for each given bit repetition number R _j (0 ≤ _j ≤ J-1), there are N _Rj (N _Rj ≥ 1) bit interleaving can be used. Similarly, NOMA mode 1 can use F _K different spreading factors (F _K ≥ 1), where the spreading factor is equal to the length of the spreading sequence, for each given spreading factor F _k (0 _{≤ k)} ≤ K-1), there are N _Fk (N _Fk ≥ 1) spreading sequences can be used. Similarly, NOMA mode 2 can use C _L different codeword lengths (C _L ≥ 1), for each given codeword length C _l (0 _{≤ l ≤ L} -1), there is N _Cl (N _Cl ≥ 1) code words can be used.

For example, each row in Table 1 (referring to the row with the smallest granularity) uniquely determines a NOMA mode and a corresponding NOMA configuration, and a network device (eg, a base station) can use signaling to notify the terminal device to use the table by indicating a row index. A line in 1 is configured to let the terminal device know the interleaving mode/spreading sequence/codeword that it should use.

Further, the "modulation method and/or code rate" in [] in Table 1 is an optional parameter, for example, it may exist in Table 1, and is combined with the interleaving method/spreading sequence/code word by indicating the row index. It can be configured for the terminal device, but it can also be used in the independent configuration. For example, related information may be configured using a PDCCH, one field in the PDCCH is used to indicate the row index of Table 1, and another independent field is used to indicate "modulation mode and/or code rate." All of the above methods can achieve adaptation of the NOMA mode and the NOMA configuration.

In this embodiment, for example, the network device may notify the terminal device of the configuration of Table 1 using dynamic signaling and/or semi-static signaling. As an implementation manner, the network device may use dynamic signaling (eg, PDCCH) to instruct the terminal device to use a certain row configuration in Table 1, so that the NOMA mode and the NOMA configuration may be dynamically switched. As another implementation manner, the network device may configure semi-static signaling (such as RRC signaling) to configure which NOMA mode the terminal device uses, and then dynamically use the dynamic signaling (eg, PDCCH) to dynamically indicate that the terminal device uses the NOMA mode. Which kind of NOMA configuration.

For another example, the network device may also notify only the part of the configuration of the table 1 to the terminal device at a time. As an implementation manner, the network device may send a certain NOMA mode and a plurality of NOMA configurations corresponding to the table 1 to the terminal device by using semi-static signaling (for example, RRC signaling), and then use dynamic signaling (for example, The PDCCH) indicates that the terminal device uses one of the plurality of NOMA configurations described above.

Thereby, adaptive adjustment of the NOMA mode and/or the NOMA configuration can be achieved.

FIG. 6 is a diagram showing an example of time-frequency resources according to an embodiment of the present invention. The adaptive adjustment of the NOMA configuration is exemplified by taking the NOMA mode based on the spread spectrum as an example; however, the present invention is not limited thereto. Where CR denotes a code rate, F denotes a spreading factor, MCS denotes a modulation and coding scheme, and RB denotes a resource block.

As shown in FIG. 6, from the perspective of a single user, OMA uses 1 RB; and since a spreading sequence is used, NOMA uses 4 RBs. However, NOMA can multiplex more terminal devices (more than 4 terminal devices) within 4 RBs. For a given size of transport block (TB), its transmission can use a variety of spreading sequences and MCS combinations (MCS includes modulation and code rate).

Different spreading factors generally correspond to different MCSs. For example, different spreading factors F in FIG. 6 correspond to different MCS 1/MCS 2. The same spreading factor may also correspond to different MCSs. For example, the same spreading factor F in FIG. 6 corresponds to different MCS 1 and MCS 2. With the embodiments of the present invention, adaptive selection can be made in various combinations (e.g., combinations of 8 spreading factors and MCS) listed in FIG.

In this embodiment, in order to support the adaptive adjustment of the above NOMA mode and/or the NOMA configuration, the calculation of the size of the transport block (TB) also needs to be modified accordingly. Currently, sections 6.1.4 and 5.1.3 of the TS 38.214 v15.0.1 standard document describe how to determine the TB size, for example, the number of resource elements (REs) to be allocated for data transmission, including first calculating 1 RB. The number of REs assigned to the data is N' _RE , and then the total number of _REs N _RE for data transmission in all RBs allocated to the terminal device is calculated, and the intermediate number of information bits N _{info is} also calculated.

Since NOMA introduces bit repetition/spreading/codewords, etc., compared with OMA, NOMA is equivalent to mapping the same information to more REs in duplicate form, and the number of REs available in the above calculation data is In fact, it is assumed that these REs carry independent information, so the redundancy caused by the copy of the information needs to be removed in the NOMA calculation. Since the number of bit repetitions/the spreading factor/codeword length and the like are adaptively changed in the above-mentioned NOMA adaptation process, the number of REs or the number of intermediate information bits required for the calculation of the TB size also needs to be adjusted accordingly.

In this embodiment, the network device and/or the terminal device may further determine, according to the multiplexing manner and/or the multiplexing configuration, a scaling factor for calculating a TB size; and determining, according to the scaling factor, the terminal device to perform information. The TB size at the time of sending or receiving.

For example, you can introduce variables

When NOMA uses bit repetition,

Equal to the number of bit repetitions; when NOMA uses a spread spectrum sequence,

Equal to the length of the spreading sequence (spreading factor); when the NOMA uses the codeword,

Equal to the codeword length. When the NOMA adaptively adjusts the number of bit repetitions/spreading factor/codeword length,

It also changes accordingly.

When calculating NOMA TB size, selection may be calculated from the following way: After the distribution obtained by calculation in a data RE to RB number N _'RE, which is further scaled

After calculating the total RE number N _RE for data transmission in all RBs allocated to the terminal device, further scaling it to

After calculating the number of intermediate information bits N _info , further scale it to

It is worth noting that the calculation process of N' _RE , N _RE and N _info before scaling, as well as other steps required to calculate the TB size, can refer to 6.1.4 and 5.1.3 in the TS 38.214 v15.0.1 standard document. The section of the present invention will not be described again.

In this embodiment, the multiplexing manner may further include one or more OMAs using orthogonal time-frequency resources and/or orthogonal codes. Furthermore, in order to assist the network device to more accurately determine the NOMA adaptation scheme, the terminal device can feed back to the network device the multiplexing mode and/or multiplexing configuration (eg, recommended NOMA mode and/or NOMA configuration) that it wishes to use.

FIG. 7 is a schematic diagram of a method for transmitting and receiving control information according to an embodiment of the present invention; further description is made from a network device side and a terminal device side. As shown in FIG. 7, the method includes:

Step 701: The terminal device feeds back information about the recommended multiplexing mode and/or multiplexing configuration to the network device.
