Description

Communication method and device

Technical Field

The present application relates to the field of communications, and more particularly, to a communication method and apparatus.

Background

In a communication system, when a network device schedules a plurality of transport blocks or a plurality of data channels by one downlink control information (downlink control information, DCI), the MCS of the scheduled transport blocks or the number of repetitions of the data channels may be indicated by a modulation and coding scheme (modulation and coding scheme, MCS) field and a number of repetitions (repetition number) field in the DCI, respectively. However, there is some state redundancy in this way of indicating the MCS and the number of repetitions. For example, a portion of the MCS may be applicable to all users, and a portion of the MCS may be applicable to only a portion of the users. For example, for a user with a lower number of repetitions, the channel quality in which the user is located may be better due to the lower number of repetitions, and a higher order MCS may be selected.

Disclosure of Invention

The application provides a communication method and device, which can reasonably specify a modulation coding mode or a transmission block size used for data transmission and the repetition times of data or control information.

In a first aspect, a communication method is provided, including: the method comprises the steps that first equipment receives control information, wherein the control information indicates the repetition times of a first information index and second information used for data transmission, and the first information is a modulation coding mode or a transmission block size; the first information index is an element in a first index set, the first index set comprising one or more first information indexes, the first index set being one of a plurality of index sets; each index set in the plurality of index sets is associated with one repetition number set, the repetition number sets associated with different index sets are different, each repetition number set comprises one or more repetition numbers, and the second information is the data or the control information; the first device determines the repetition number of second information according to the control information, wherein the repetition number of the second information is an element in a repetition number set associated with a first index set; when the second information is data, the first device determines a transport block size used for transmitting the data according to the first information index, and the first device sends or receives the data according to the transport block size and the repetition number; and/or when the second information is control information, the first device determines a transport block size used for transmitting the data according to the first information index, determines a timing required for transmitting the data according to the repetition number, and the first device transmits or receives the data according to the transport block size and the timing.

Detailed Description

The technical solutions in the present application will be described below with reference to the accompanying drawings.

The technical solution of the embodiment of the application can be applied to various communication systems, for example: global system for mobile communications (global system for mobile communications, GSM), code division multiple access (code division multiple access, CDMA) system, wideband code division multiple access (wideband code division multiple access, WCDMA) system, general packet radio service (general packet radio service, GPRS), long term evolution (long term evolution, LTE) system, LTE frequency division duplex (frequency division duplex, FDD) system, LTE time division duplex (time division duplex, TDD), universal mobile telecommunications system (universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX) communication system, future fifth generation (5th generation,5G) system or New Radio (NR) air interface, and the like.

To facilitate understanding of the embodiments of the present application, a communication system suitable for use in the method provided in the embodiments of the present application will be described in detail with reference to fig. 1. Fig. 1 shows a schematic diagram of a communication system 100 suitable for use in the methods provided in embodiments of the present application. As shown, the communication system 100 may include at least one network device, such as a base station (gNB) in the 5G system shown in fig. 1; the communication system 100 may further include at least one terminal device, such as User Equipment (UE) 1 to UE 6 shown in fig. 1. The network device and each terminal device may communicate via a wireless link. For example, the network device may send configuration information to the terminal device, and the terminal device may send uplink data to the network device based on the configuration information; as another example, the network device may send downstream data to the terminal device. Thus, the gNB and the UEs 1 to 6 in FIG. 1 may constitute one communication system.

The terminal devices, e.g., UE 4 to UE 6, in the communication system 100 may also constitute a communication system. For example, UE 4 may control UE 5 and UE 6 to execute respective instructions. The present application is not limited in this regard.

It should be understood that the network device in the communication system may be any device having a wireless transceiving function. The network devices include, but are not limited to: an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (home evolved NodeB, or a home Node B, HNB, for example), a Base Band Unit (BBU), an Access Point (AP) in a wireless fidelity (wireless fidelity, wiFi) system, a wireless relay Node, a wireless backhaul Node, a transmission point (transmission point, TP), or a transmission reception point (transmission and reception point, TRP), etc., may also be 5G, e.g., NR, a gNB in a system, or a transmission point (TRP or TP), one or a group of base stations (including multiple antenna panels) in a 5G system, or may also be a network Node constituting a gNB or a transmission point, such as a baseband Unit (BBU), or a Distributed Unit (DU), etc.

In some deployments, the gNB may include a Centralized Unit (CU) and DUs. The gNB may also include a Radio Unit (RU). The CU implements part of the functions of the gNB, the DU implements part of the functions of the gNB, for example, the CU implements the functions of a radio resource control (radio resource control, RRC), a packet data convergence layer protocol (packet data convergence protocol, PDCP) layer, and the DU implements the functions of a radio link control (radio link control, RLC), a medium access control (media access control, MAC), and a Physical (PHY) layer. Since the information of the RRC layer may eventually become information of the PHY layer or be converted from the information of the PHY layer, under this architecture, higher layer signaling, such as RRC layer signaling, may also be considered to be transmitted by the DU or by the du+cu. It is understood that the network device may be a CU node, or a DU node, or a device comprising a CU node and a DU node. In addition, the CU may be divided into network devices in an access network (radio access network, RAN), or may be divided into network devices in a Core Network (CN), which is not limited in this application.

The terminal device may also be a cellular telephone, a cordless telephone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal digital assistant, PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved public land mobile network (public land mobile network, PLMN), etc., as the embodiments of the application are not limited in this respect.

It should also be appreciated that fig. 1 is a simplified schematic diagram that is merely illustrative for ease of understanding, and that other network devices or other terminal devices may be included in the communication system 100, which are not shown in fig. 1.

To facilitate understanding of the embodiments of the present application, a simple explanation of the transport block concept is first provided.

Transport Block (TB): the transport block may be a data block from a higher layer. A transport block may for example comprise a data block of a medium access control (media access control, MAC) protocol data unit (protocol data unit, PDU), which may be transmitted over a time unit or may be a unit of HARQ retransmission. The transport block may also be a code block or a group of code blocks.

In a communication system, typically one control information, e.g. downlink control information (Downlink Control Information, DCI), may schedule one transport block or schedule a transport block carried by one data channel. The data channel may be, for example, a physical downlink data channel or a physical uplink data channel.

In order to reduce the overhead of control information transmission and save transmission resources, a plurality of transport blocks may be scheduled with one control information. When the network device schedules a plurality of transport blocks through one control information, the number of repetitions may be indicated by using a repetition number field in the control information, and the MCS may be indicated through an MCS field. If the protocol defines the number of repetitions of the MCS of N (N.gtoreq.1 and integer) and M (M.gtoreq.1 and integer), then it may be necessary

A bit to indicate MCS and require +.>

A number of bits to indicate the number of repetitions. However, there is some state redundancy in this way of indicating the MCS and the number of repetitions. For example, a portion of the MCS may be applicable to all users, and a portion of the MCS may be applicable to only a portion of the users. For example, for a user with a lower number of repetitions, the channel quality in which the user is located may be better due to the lower number of repetitions, and a higher order MCS may be selected.

And as the values of N and M increase, the required indication bits also increase.

Therefore, if the same indication bit is used for all users to indicate the repetition number and MCS, redundancy of the indication bit may exist. And thus the resource usage is not high.

Therefore, it is desirable to provide a method for reasonably specifying the modulation and coding scheme or transport block size used for data transmission and the number of repetitions of the data or control information. In order to facilitate understanding of the embodiments of the present application, the following description is made before describing the embodiments of the present application.

First, in the embodiments of the present application, "indication" may include a direct indication and an indirect indication, and may also include an explicit indication and an implicit indication. The information indicated by a certain information (the first indication information described below) is called to-be-indicated information, and in a specific implementation process, there are various ways to indicate to-be-indicated information, for example, but not limited to, the to-be-indicated information may be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The information to be indicated can also be indicated indirectly by indicating other information, wherein the other information and the information to be indicated have an association relation. It is also possible to indicate only a part of the information to be indicated, while other parts of the information to be indicated are known or agreed in advance. For example, the indication of the specific information may also be achieved by means of a pre-agreed (e.g., protocol-specified) arrangement sequence of the respective information, thereby reducing the indication overhead to some extent.

Second, the first, second and various numerical numbers in the embodiments shown below are merely for convenience of description and are not intended to limit the scope of the embodiments of the present application. For example, different indication information is distinguished, etc.

Third, in the embodiments shown below, "pre-fetching" may include signaling by the network device or pre-defining, e.g., protocol definition. The "pre-defining" may be implemented by pre-storing corresponding codes, tables or other manners that may be used to indicate relevant information in devices (including, for example, terminal devices and network devices), and the application is not limited to a specific implementation manner thereof.

Fourth, the "protocol" referred to in the embodiments of the present application may refer to a standard protocol in the field of communications, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied in a future communication system, which is not limited in this application.

Fifth, reference to "a plurality of" in embodiments of the present application refers to two or more. "the following item(s)" or "items(s)" or the like, refer to any combination of these items, including any combination of single item(s) or plural item(s). For example, at least one (one) or more (ones) of a, b and c may represent: a, b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b and c can be single or multiple.

Sixth, references to predefine in embodiments of the present application may be understood as defining, predefining, storing, pre-negotiating, pre-configuring, curing, or pre-firing.

Seventh, a plurality of index sets in the embodiment of the present application may be defined as one. In other words, the "multiple index sets" in the embodiments of the present application may be replaced with "one or more index sets".

The method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

Optionally, the first device is a terminal device, or a chip configured in the terminal device; the second device is a terminal device or a chip configured in the terminal device. The embodiments shown below are not limiting as to the scenarios to which the methods provided herein are applicable.

Hereinafter, the embodiments of the present application will be described in detail by taking interaction between a first device and a second device as an example. Fig. 2 is a schematic flow chart illustrating a repetition number indication method 200 provided by an embodiment of the present application from a device interaction perspective. As shown, the method 200 may include step 210 and step 240. The various steps in method 200 are described in detail below.

The second device determines control information, step 210. The control information may indicate the number of repetitions of the first information index and the second information used for data transmission. Specifically, the first information is a modulation coding scheme or a transport block size. The first information index may be an index of a modulation coding scheme or an index of a transport block size. The second information may be data or control information. In this embodiment of the present application, the first information index is an element in the first index set, or the first information index belongs to the first index set. The first index set includes one or more first information indexes. The first index set to which the first information index belongs is one index set of a plurality of index sets. Each first index set of the plurality of index sets may be associated with a repetition number set, and the repetition number sets associated with different index sets are different. One or more repetition times may be included in each set of repetition times. The number of repetitions of the second information indicated by the control information may specifically refer to one repetition in the set of repetitions associated with the first information index.

In this embodiment of the present application, the repetition number set associated with the first index set may refer to a repetition number set associated with a modulation and coding scheme index set, or may refer to a repetition number set associated with a transport block size index set. The modulation and coding scheme and the transport block size may have a corresponding relationship. For example, table 14 below shows an example of the modulation and coding scheme index and the transport block size index. Thus, when one of the modulation coding scheme index set or the transport block size index set is associated with the repetition number set, the other is also associated with the repetition number set.

Optionally, the first index set is one of a plurality of index sets. Wherein the plurality of index sets may be preconfigured. E.g. protocol definition, or the second device is pre-configured to the first device by signalling. The present application is not limited in this regard.

Optionally, each index set of the plurality of index sets may be associated with a repetition number set, and the repetition number sets associated with different index sets of the plurality of index sets are different, each repetition number set containing one or more repetition numbers.

Optionally, the set of repetition times associated with each of the plurality of sets of indices may be specified or predefined by the communication protocol.

Optionally, the first information index in any two index sets is not repeated in the preconfigured plurality of index sets. In other words, the intersection of any two index sets is an empty set.

Optionally, the first device receives first indication information, where the first indication information indicates or configures a repetition number set associated with each of the plurality of index sets.

Alternatively, the first device may receive the first indication information sent by the second device.

Alternatively, in the case that the above-mentioned one repetition number set may include 1 element, all MSC indexes may be applicable to an application scenario of non-repeated or low-repetition transmission data.

Where max refers to the maximum value. For example, max {4,1} = 4.

Optionally, the correspondence between the plurality of index sets and the plurality of repetition number sets corresponding to the plurality of index sets may be optimized. For example, when the index is 0 to 4, it indicates that the data channel quality is not good, and thus the number of repetitions corresponding to the index is relatively large, so that the number of repetitions is selected to ensure that the control information schedules highly reliable transmission of the data channel. For another example, when the index is 5 to 9, the index value is relatively moderate, which indicates that the data channel quality is acceptable, so that the index corresponds to a relatively moderate number of repetitions, and the performance of data channel transmission can be ensured by selecting a relatively moderate number of repetitions. For another example, when the index is 10 to 15, it is indicated that the channel quality is good, and therefore, the index corresponds to a relatively low repetition number, so that the performance of data channel transmission can be ensured.

Alternatively, the multiple index sets listed above and the set of repetition times associated with the multiple index sets may be applicable, for example, to the first device being in coverage enhancement mode B, or the first device being at coverage enhancement level 2, or the first device being at coverage enhancement level 3.

Optionally, the multiple index sets and the repetition number sets associated with the multiple index sets may be optimized.

It should be appreciated that tables 1 through 13 above illustrate several examples of sets of repetition times associated with multiple sets of indices. But this should not constitute any limitation to the present application.

Step 220, the first device receives control information. Accordingly, in step 220, the second device transmits the control information. The control information may be control information determined by the second device in step 210, and the control information may be referred to the above description and will not be described in detail here.

Alternatively, the second device may independently indicate the number of repetitions of the first information index and the second information index used for data transmission, that is, the second device may independently indicate the modulation coding scheme or the transmission block size index used for data transmission, and the number of repetitions of the data or the control information, that is, the second device may separately indicate the modulation coding scheme or the transmission block size index used for data transmission, and the number of repetitions of the data or the control information, with two fields.

Illustratively, the second device may indicate the index of the modulation coding scheme or the transport block size with X bits and independently indicate the number of repetitions of the data or control channel with Y bits. For example, as shown in table 1, when the plurality of index sets is 3 index sets and the values in the 3 index sets are 0 to 15, there may be 16 values, then x=log ₂ 16 =4; the number of repetitions in the repetition number set associated with each index set may be two of n1, n2, n3, n4, then y=log ₂ 2=1. That is, the second device may indicate the index of the modulation coding scheme or the transport block size with 4 bits and may independently indicate the number of repetitions of the data channel or the control channel with 1 bit.

For example, the second device may indicate an index of a modulation coding scheme or a transport block size used for data transmission with L bits and independently indicate the number of repetitions of data or control information with P bits. For example, as shown in table 4, when the plurality of index sets includes 2 index sets and the values in the 2 index sets are 0 to 9, there may be 10 values, then l=log ₂ 10 =4; the number of repetitions in the set of the number of repetitions of the data or control information may be m1, m2, m3, m4, m5, m6, m7. At least four of m8, then p=log ₂ 4=2. That is, the second device may use 4 bits to indicate the index of the modulation coding scheme or the transport block size used for data transmission, and use 2 bits to independently indicate the number of repetitions of data or control information.

Illustratively, as shown in table 6, when the plurality of index sets includes 2 index sets, and the values in the 2 index sets are 0 to 7, there may be 8 values, then l=log ₂ 8=3; the number of repetitions in the set of the number of repetitions of the data or control information may be at least four of m1, m2, m3, m4, m5, m6, m7, and m8, and p=log ₂ 4=2. That is, the second device may use 3 bits to indicate the index of the modulation coding scheme or the transport block size used for data transmission, and use 2 bits to independently indicate the number of repetitions of data or control information.

Alternatively, the second device may also jointly indicate the number of repetitions of the first information index and the second information for data transmission, i.e. the second device may also jointly indicate the modulation coding scheme or the index of the transport block size for data transmission, and the number of repetitions of the data or the control information, i.e. the second device may use the same field to indicate the modulation coding scheme or the index of the transport block size for data transmission, and the number of repetitions of the data or the control information.

Illustratively, as shown in table 1, the second device may jointly indicate the index of the modulation coding scheme or transport block size used for data transmission and the repetition number of data or control information with 5 bits.

Illustratively, as shown in table 4, the second device may jointly indicate the index of the modulation coding scheme or transport block size used for data transmission and the repetition number of data or control information with 6 bits. Illustratively, as shown in table 6, the second device may jointly indicate the index of the modulation coding scheme or transport block size used for data transmission and the repetition number of data or control information with 5 bits.

According to the actual situation, the first device and the second device can reasonably allocate the repetition times of the data channel or the control channel associated with the modulation coding mode or the transmission block size, and meanwhile, the signaling overhead can be reduced, and the transmission performance of the data channel or the control channel is improved.

In step 230, the first device determines the repetition number of the second information according to the control information.

Optionally, the first device may determine the number of repetitions of the second information in the set of repetitions associated with the first set of indices. I.e. the number of repetitions of the second information is an element of the set of repetitions associated with the first index set.

Illustratively, if the first index set {0,1,2,3,4,5,6,7}, the number of repetitions of the second information is an element of the first index set {0,1,2,3,4,5,6,7} associated with the number of repetitions { n1, n2}, i.e., the first device may determine the number of repetitions of the second information in the first index set {0,1,2,3,4,5,6,7} associated with the number of repetitions { n1, n2}, the number of repetitions of the second information may be n1, or the number of repetitions of the second information may be n2.

Illustratively, if the first index set {8,9, 10, 11, 12, 13, 14, 15}, the number of repetitions of the second information is an element of the first index set {8,9, 10, 11, 12, 13, 14, 15} associated with the number of repetitions { n3, n4}, i.e., the first device may determine the number of repetitions of the second information from the first index set {8,9, 10, 11, 12, 13, 14, 15} associated with the number of repetitions { n3, n4}, the number of repetitions of the second information may be n3, or the number of repetitions of the second information may be n4.

In step 240, the first device transmits data with the second device according to the first information index and the repetition number of the second information.

Alternatively, the first device may determine a transport block size used for transmitting the data according to the first information index.

Optionally, there is a certain correspondence between the modulation and coding scheme in the first information and the size of the transport block. Table 14 shows an example of the correspondence between the modulation and coding scheme index of the data channel and the transport block size index. Wherein, when the modulation order is 2, the modulation method corresponds to a quadrature phase shift keying (quadrature phase shift keying, QPSK) modulation method, when the modulation order is 4, the modulation method corresponds to a quadrature amplitude modulation (quadrature amplitude modulation, QAM) method of 16 symbols, and when the modulation order is 6, the modulation method corresponds to a modulation method of 64 QAM; that is, the modulation and coding schemes corresponding to the modulation and coding scheme indexes 0 to 9 and 29 may be QPSK, the modulation and coding schemes corresponding to the modulation and coding scheme indexes 10 to 16 and 30 may be 16QAM, and the modulation and coding schemes corresponding to the modulation and coding scheme indexes 17 to 28 and 31 may be 64QAM.

TABLE 14

The correspondence relationship shown in table 14 may be configured or predefined. The values of the indication information in each table are merely examples, and may be configured as other values, which are not limited in this application. When the correspondence relation between the instruction information and each parameter is configured, it is not necessarily required to configure all the correspondence relations shown in each table. For example, in the above table, the correspondence relationship shown by some rows may not be configured. For another example, appropriate morphing adjustments, e.g., splitting, merging, etc., may be made based on the tables described above. The names of the parameters shown in the tables may be other names which are understood by the communication device, and the values or representations of the parameters may be other values or representations which are understood by the communication device. When the tables are implemented, other data structures may be used, for example, an array, a queue, a container, a stack, a linear table, a pointer, a linked list, a tree, a graph, a structure, a class, a heap, a hash table, or a hash table.

Alternatively, according to table 14, the first device may determine the size of the transport block used for transmitting the data according to the correspondence between the modulation and coding scheme and the size of the transport block. Accordingly, the second device may also determine the transport block size used to transmit the data.

Alternatively, in the case where the second information is data, the first device may also transmit or receive the data according to the transport block size and the number of repetitions of the second information. Accordingly, the second device may also receive or transmit data according to the transport block size and the repetition number of the second information.

Since a specific method of the first device transmitting data according to the transport block size and timing is the same as that of the related art, a detailed description of the specific process is omitted herein for brevity.

Alternatively, in the case where the second information is control information, the first device may also determine a timing required to transmit data according to the number of repetitions of the control information, and the first device may transmit or receive the data according to the transport block size and timing. Accordingly, the second device may also determine a transport block size used to transmit the data and a timing required to transmit the data, and the second device may receive or transmit the data according to the transport block size and the timing. The data may be, for example, data scheduled by control information.

Since the first device determines the timing of data according to the number of repetitions of control information and a specific method of transmitting data according to the transport block size and timing are the same as the prior art, a detailed description of the specific procedure is omitted herein for brevity.

Alternatively, the data transmitted between the first device and the second device may be data transmitted between a network device and a terminal device. Alternatively, the data transmitted between the first device and the second device may be data transmitted between the terminal device and the terminal device. For example, the first device may encode the uplink data using a modulation coding scheme associated with the repetition number of the data or the control information, and transmit the uplink data to the second device on the corresponding transport block.

The first device receives the downlink data sent by the second device on the corresponding transmission block according to the modulation coding mode used for transmitting the data or the index of the transmission block size, and the first device can decode the downlink data by adopting the modulation coding mode of the data.

Based on the above technical solution, the first device determines the repetition number of data or control information according to the repetition number set associated with the modulation coding scheme or the transport block size index used for data transmission, and further sends or receives the data according to the transport block size and the repetition number of the data, or the first device determines the timing required for transmitting the data according to the repetition number of the control information, and sends or receives the data according to the transport block size and the timing required for transmitting the data. Therefore, the number of repetitions of the second information in the embodiment of the present application is determined by the number of repetitions in the set of repetitions associated with the first information index. The first information index is used for associating the repetition number set, so that the second equipment can select different repetition number sets according to actual conditions, and the modulation coding mode, the transmission block size and the repetition number of the data or control information for data transmission are reasonably specified. And under the condition that the number of the repetition times contained in the repetition times set is smaller, the second device can adopt fewer indication bits to indicate the repetition times, so that the signaling overhead of the control information is reduced, and the utilization rate of resources is improved. It should be understood that, in the foregoing embodiments, the sequence number of each process does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not constitute any limitation on the implementation process of the embodiments of the present application.

The schematic structure of the network device shown in fig. 5 may be, for example, a schematic structure of a base station. The base station 3000 may be applied to the system shown in fig. 1, and perform the functions of the second device in the above method embodiment. As shown, the base station 3000 may include one or more radio frequency units, such as a remote radio frequency unit (remote radio unit, RRU) 3100 and one or more baseband units (BBUs) (also referred to as Distributed Units (DUs)) 3200.
