The present application claims priority to Chinese Patent Application No. PCT Application No. No. No. No. No. No. No. No. No. No. No. No.

Technical field

The present application relates to the field of communications and, more particularly, to methods and apparatus for transmitting information in the field of communications.

Background technique

With the development of communication systems in the future, different services have different requirements for mobile communication systems, and different services have different requirements for the length of control information. The length of control information may be the number of symbols of control information in time domain resources, for example, high. Ultra reliable and low latency communications (URLLC) services require high reliability and may require long control information. For example, mass machine type communications (mMTC) services require resource requirements. Larger, may require shorter control information. A time scheduling unit includes a fixed number of symbols, for example, seven. In the prior art, if the length of the control information is 4, there will be no signals transmitted on the three idle symbols, which may result in waste of resources; for example, If a time scheduling unit includes 14 symbols and a control information has a length of 12, there will be no signals transmitted on 2 idle symbols, or the length of one control information is 5, and the transmission of one control information is 7. Then, two control information can be sent in the time scheduling unit, but there are still no signals transmitted on the two symbols. Therefore, the existing method of transmitting the control information may cause waste of resources, resulting in poor system performance.

detailed description

It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, for example, a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, and a wideband code. Wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) System, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication system, wireless local area network (wireless local area) Network, WLAN) or the fifth generation of the fifth generation wireless communication system (the fifth generation, 5G).

FIG. 1 shows a communication system 100 to which an embodiment of the present application is applied. The communication system 100 can include a terminal device 110, which can be referred to as an access terminal, a subscriber unit, a subscriber station, a mobile 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 device. . The access terminal may be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), with wireless communication. Functional handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminals in 5G networks, and the like.

The network device 120 may be a network side device that performs wireless communication with the terminal device 110, for example, a wireless-fidelity (Wi-Fi) access point, a base station of a next-generation communication, such as a 5G gNB or The small station, the micro station, and the transmission reception point (TRP) may also be base stations in 2G, 3G, and 4G, and may also be relay stations, access points, in-vehicle devices, wearable devices, and the like.

It should be understood that the terminal device 110 may be one or more. The embodiment of the present application is described by taking only one terminal device as an example.

The nouns used in the embodiments of the present application are explained below:

Pilot symbols, pilot sequence mappings generate pilot symbols on pilot patterns.

The pilot sequence is used to represent a series of values of the pilot, and the value belongs to a value in the complex set. The cross-correlation between the pilot sequences decreases as the sequence length increases, that is, the longer the length of the pilot sequence, the interference The smaller the pilot sequence, the smaller the length, indicating greater interference.

Control information, the control information in the embodiment of the present application may control data symbols of the information, and the data symbols of the control information may be used to map the uplink control information to symbols generated by orthogonal frequency division multiplexing (OFDM) symbols. In order to avoid redundancy, the data symbols of the control information are simply referred to as data symbols.

Symbols, including but not limited to orthogonal frequency division multiplexing (OFDM) symbols, sparse code multiplexing access (SCMA) symbols, filtered orthogonal frequency division (filtered orthogonal frequency division) The multiplexing, F-OFDM, and non-orthogonal multiple access (NOMA) symbols may be determined according to actual conditions, and are not described here.

One time scheduling unit includes 14 symbols, and FIG. 2 shows the case where 4, 5, 9, 10, 13, and 14 symbol resources are occupied, respectively. Each row includes a pilot symbol and a data symbol of control information. The pilot symbol is used by the receiving end for channel estimation, and the result of the channel estimation can be used to assist in demodulating the data symbol of the control information. The abscissa is time, each grid occupies 1 symbol in time, the ordinate is frequency, and each grid is in the frequency minimum frequency unit (such as 12 subcarriers). Among them, the non-white is the control information and the pilot symbol part (black is the pilot symbol, the diagonal stripe is the data symbol of the control information), and the white is the empty resource. It can be seen that the control information and the pilot symbols corresponding to less than 7 symbols, such as the 5 symbols, can be placed once in the first 7 symbols of the 14 symbols, that is, there is a waste of 2 symbols (the waste symbol is represented by X); Corresponding to control information and pilot symbols greater than 7 symbols, such as 13 symbols, there is a waste of 1 symbol. Unless there are more than two symbols spliced together to exactly 14 symbols, such as 1 9 symbols + 5 symbols are sent in time. However, in the actual scheduling, the scheduling unit does not necessarily have exactly one 9 symbols and one 5 symbols transmitted at the same time, so the waste of resources is difficult to avoid.

Therefore, for the above problem, the embodiment of the present application proposes that multiple pilot symbols can be consecutive in the entire time scheduling unit, and pilot symbols can overlap, for example, as shown in FIG. 3, one time scheduling unit (including 14) Two sets of information can be transmitted in the symbol), each set of information includes 6 data symbols and 2 pilot symbols, wherein the pilot symbols of the two sets of information are overlapped, assuming that the information in each group is similar to that in FIG. Occupying a time scheduling unit, each group of information will be wasted 6 symbols, so that the two sets of information will be wasted 12 symbols. For another example, as shown in FIG. 4, two time information may be transmitted in a time scheduling unit (including 14 symbols), the first group information includes 6 data symbols and 2 pilot symbols of control information, and the second group information includes control. 5 data symbols of information and 2 pilot symbols, wherein the two pilot symbols of the first group of information and the second group of information are overlapped, only one symbol is wasted; assuming a method similar to that of FIG. 2, first The group information occupies 8 symbols of a time scheduling unit, and 6 symbols are wasted. The second group of information occupies 7 symbols of a time scheduling unit, and the other 7 symbols of the time scheduling unit can send another length less than or equal to The information of 7 is that, if the method similar to FIG. 2 is adopted, at least 6 symbols are wasted. Therefore, the method of the embodiment of the present application can avoid waste of resources.

As an example, in the embodiment of the present application, the data symbols of the pilot symbol and the control information may be arranged as shown in FIG. 5 to FIG. 8 , wherein the black grid represents the pilot symbol, and the lattice of the diagonal stripe represents the control. The data symbols of the information, the ellipses in FIG. 7 indicate the symbols of other control information, for example, other pilot symbols and data symbols, and other control information may be inserted between the pilot symbols and the data symbols of the control information (eg, FIG. 7) However, the multiple pilot symbols corresponding to one control information in the embodiment of the present application may be consecutive multiple pilot symbols.

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

FIG. 9 shows a communication method 200 of an embodiment of the present application. The method 200 can be applied to the communication system 100 shown in FIG. 1, but the embodiment of the present application is not limited thereto.

S210: The first terminal device generates first control information, where the first pilot is used to demodulate the first control information, where the first pilot includes n consecutive pilot symbols, where At least one of the n consecutive pilot symbols is the same as the time domain resource occupied by at least one of the m consecutive pilot symbols included in the second pilot transmitted by the second terminal device to the network device. The second pilot is used to demodulate the second control information sent by the second terminal device to the network device, where m and n are integers greater than 1.

In other words, the n consecutive pilot symbols at least partially overlap with the time domain resources occupied by the m consecutive pilot symbols, specifically, n consecutive pilot symbols and m consecutive pilot symbols The occupied time-frequency resources all overlap or partially overlap. For example, when n is equal to m, the time-frequency resources occupied by n consecutive pilot symbols and m consecutive pilot symbols may all overlap, that is, when n symbols The domain resources overlap, and may be symbols with less than n numbers of overlaps; when n is greater than m, the n consecutive pilot symbols and the m consecutive pilot symbols occupy the time domain resources may overlap m symbols, or The symbols are less than m number of symbols; when n is less than m, n consecutive pilot symbols and m consecutive pilot symbols occupy the time domain resource may overlap n symbols, or may overlap less than n number of symbols. The at least partially overlapping indicates that the overlapped portion is at least one symbol, for example, the first pilot includes 3 consecutive pilot symbols, and the second pilot includes 2 consecutive pilot symbols, and then a guide of the first pilot The frequency symbol may overlap with a time domain resource occupied by one pilot symbol of the second pilot; or two consecutive pilot symbols of the first pilot (may be the first two of the three consecutive pilot symbols) The time domain resources occupied by consecutive pilot symbols or the following two consecutive pilot symbols and the two consecutive pilot symbols of the second pilot may overlap.

It should be understood that the first terminal device and the second terminal device may be different terminal devices; the first control information and the second control information may be different control information. The first terminal device and the second terminal device may be the same. If the first terminal device and the second terminal device are the same terminal device, the first control information and the second control information share the same. The pilot signal is demodulated, for example, a pilot signal that transmits only one of the control information, such as the one that transmits the pilot symbol. As described above, when m is greater than n, only m pilot signals are transmitted, and the m pilot signals are the common pilot symbols.

Optionally, the first pilot comprises n consecutive pilot symbols; the second pilot comprises m consecutive pilot symbols.

In a possible implementation manner, the n consecutive pilot symbols at least partially overlap with a time domain resource occupied by the m consecutive pilot symbols; the n consecutive pilot symbols and the The frequency domain resources occupied by the m consecutive pilot symbols may overlap or not overlap. When the frequency domain resources also overlap, the pilot symbols of the overlapping portion may be orthogonal by code division; when the frequency domain resources do not overlap Then, the pilot symbols of the overlapping portion of the time domain may be orthogonal by frequency division. For example, as shown in FIG. 10, the horizontal direction represents time and the vertical direction represents frequency. The two columns in FIG. 10 indicate that the pilot symbols occupy two time domains. Symbol, FIG. 10 is a schematic diagram of pilot symbols of two time domain symbols of one frequency unit, one frequency unit includes 12 subcarriers (12 rows in FIG. 10, each row represents one subcarrier), for example, black indicates the first terminal The time-frequency resource occupied by two consecutive pilot symbols of the device, and the oblique line stripe is the time-frequency resource occupied by two consecutive pilot symbols of the second terminal device, that is, the guide of two terminal devices on the frequency The frequencies are separated and do not overlap. Specifically, the overlapping partial orthogonalities may be orthogonal to the pilot sequences corresponding to the overlapping pilot symbols.

Optionally, the time domain locations of the n consecutive pilot symbols occupying the first control information may have three time domain locations:

First, the n consecutive pilot symbols are in the time domain in front of the first control information (eg, Figures 6 and 7). Specifically, the manner in which the n consecutive pilot symbols overlap with the m consecutive pilots may be an overlapping manner as shown in FIG. 11, where n is 2 in FIG. 11 and FIG. 12, and m is 2 whole time scheduling units. Including 14 symbols, two pilot symbols of the first pilot and two pilot symbols of the second pilot overlap (the first two symbols in the 14 symbols), in FIG. 11, the third to the third 8 symbols are 6 data symbols included in the first control information, and the 9th to 14th symbols are 6 data symbols included in the second control information. Of course, as shown in FIG. 12, the third to the eighth The symbol may also be 6 symbols included in the second control information, and the 9th to 14th symbols are 6 data symbols included in the first control information. For another example, as shown in FIG. 13, a time scheduling unit includes 14 symbols, the first pilot includes 3 pilot symbols, the first control information includes 6 data symbols, and the second pilot includes 2 pilot symbols. The second control information includes five data symbols, wherein the pilot symbols of the first pilot and the pilot symbols of the second pilot occupy the first three symbols (the black portion in FIG. 13), and the fourth to the ninth The symbols are the data symbols of the first control information, and the 10th to 14th symbols are the data symbols of the second control information, and the arrangement of the first 3 pilot symbols may be the arrangement of FIG. 13: the second control The two pilot symbols of the pilot occupy the first two symbols, and the three pilot symbols of the first pilot occupy the first three symbols, and the first two symbols are overlapped. Of course, as shown in FIG. 14 , the two pilot symbols of the second pilot may also occupy the second and third symbols, which is not limited in this embodiment of the present application. Optionally, as shown in FIG. 15 , the five data symbols of the second control information may be in front of the six data symbols of the first control information, which is not limited in this embodiment of the present application. In Fig. 13 to Fig. 15, m is 2 and n is 3.

Second, the n consecutive pilot symbols are in the time domain behind the first control information (eg, FIG. 5). For example, the manner in which the n consecutive pilot symbols overlap with the m consecutive pilots may be an overlapping manner as shown in FIG. 16. The entire time scheduling unit includes 14 symbols, and the first pilot has three pilots. The last two pilot symbols in the symbol overlap with the two pilot symbols of the second pilot (the eighth and ninth symbols in the 14 symbols), and the first to sixth symbols are the first control information. The 6 data symbols included, the 10th to 14th symbols are 5 data symbols included in the second control information. For another example, the manner in which the n consecutive pilot symbols overlap with the m consecutive pilots may be an overlapping manner as shown in FIG. 17, and the entire time scheduling unit includes 14 symbols, and the third pilot of the first pilot The first two pilot symbols in the frequency symbol overlap with the two pilot symbols of the second pilot (the seventh and eighth symbols in the 14 symbols), and the first to sixth symbols are the first control The information includes 6 data symbols, and the 10th to 14th symbols are 5 data symbols included in the second control information. In Fig. 16 and Fig. 17, m is 2 and n is 3.

Third, the n consecutive pilot symbols are between the first control information (e.g., Figure 8). For example, the manner in which the n consecutive pilot symbols overlap with the m consecutive pilots may be an overlapping manner as shown in FIG. 18. The entire time scheduling unit includes 14 symbols, and the first pilot has three pilots. The last two pilot symbols in the symbol overlap with the two pilot symbols of the second pilot (the fifth and sixth symbols in the 14 symbols), of course, the two pilot symbols of the second pilot may occupy The 4th and 5th symbols, such overlapping parts are the 4th and 5th symbols. The 1st to 3rd symbols and the 7th to 9th symbols are 6 data symbols included in the first control information, and the 10th to 14th symbols are 5 data symbols included in the second control information. In Fig. 18, m is 2 and n is 3.

As an optional embodiment, the method 200 further includes: the network device sending the first indication information to the first terminal device, where the first terminal device receives the first indication information sent by the network device, where The first indication information is used to indicate one of the foregoing three manners, for example, the n consecutive pilot symbols are in front of or behind the first control information in a time domain, and the first terminal device is configured according to the first terminal device.
