Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission method and related products. Background Art

[0002] For the Physical Uplink Control Channel (PUCCH), in the Rel-15 New Radio (NR) system, the PUCCH frequency domain resources can be configured with 1 to 16 physical resource blocks (PRBs). However, in the New Radio Unliecensed (NR-U) system, due to the limitation of occupied bandwidth (OCB), the information transmitted on the PUCCH needs to be mapped using comb interlace. The frequency domain resources of an interlace are 10 or 11 PRBs, which leads to the fact that in some cases, such as when the load on the PUCCH is large, the frequency domain resources corresponding to an interlace cannot carry too much load, and two or more interlaces are needed for transmission. In addition, in order to improve the utilization rate of the frequency domain resources of the interlace, when the PUCC is in Format 2, when the interlace is used, the physical resource blocks of the frequency domain resources of the interlace can also be reused through orthogonal cover codes (OCC), thereby increasing the number of user multiplexing.

[0003] However, when the number of multiplexed users is increased, the information transmitted on the PUCCH will be repeated more, resulting in a high peak to average power ratio (PAPR), which in turn affects the information transmission process on the PUCCH. Summary of the invention

[0015] In a fifth aspect, an embodiment of the present application provides a terminal device, comprising a processor, a memory, a communication interface, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the processor, and the program includes instructions for executing the steps in the method described in the first aspect of the embodiment of the present application.

[0016] In a sixth aspect, an embodiment of the present application provides a network device, comprising a processor, a memory, a communication interface, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the processor, and the program includes instructions for executing the steps in the method described in the second aspect of the embodiment of the present application.

[0032] The terms used in the implementation mode of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The terms "first", "second", "third" and "fourth" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0033] The embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced long term evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-based access to unlicensed spectrum, LTE-U) system, NR on unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next generation communication system or other communication systems, etc.

[0034] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device to device (Device to Device, D2D) communication, machine to machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), and vehicle to vehicle (Vehicle to Vehicle, V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0035] Optionally, the communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0036] The embodiments of the present application do not limit the spectrum to which they are applied. For example, the embodiments of the present application can be applied to licensed spectrum or unlicensed spectrum.

[0037] Figure 1 The present invention provides a communication system architecture schematic diagram, wherein the communication system includes a network device and a terminal device. Figure 1 As shown, the network device can communicate with the terminal device. The communication system can be a 5G communication system (such as a new radio (NR)), a communication system integrating multiple communication technologies (such as a communication system integrating LTE technology and NR technology), or a subsequent evolution communication system. Figure 1 The forms and quantities of the network devices and terminal devices shown are for example only and do not constitute a limitation on the embodiments of the present application.

[0038] The terminal device in this application is a device with wireless communication function, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (for example, on airplanes, balloons, satellites, etc.). The terminal device can be a mobile phone, a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in smart home, etc. The terminal device can also be a handheld device with wireless communication function, a vehicle-mounted device, a wearable device, a computer device or other processing device connected to a wireless modem, etc. Terminal devices may be called different names in different networks, such as: terminal equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), terminal equipment in 5G network or future evolution network, etc.

[0039] The network device in the present application is a device deployed in a wireless access network to provide wireless communication functions. For example, the network device can be a radio access network (RAN) device on the access network side of a cellular network. The so-called RAN device is a device that connects a terminal device to a wireless network, including but not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., Home evolved Node B, or Home Node B, HNB), base band unit (BBU), management entity (MME); for another example, the network device can also be a node device in a wireless local area network (WLAN), such as an access controller (AC), a gateway, or a WIFI access point (AP); for another example, the network device can also be a transmission node or a transmission reception point (TRP or TP) in an NR system.

[0040] Unlicensed spectrum is the spectrum allocated by countries and regions that can be used for radio equipment communications. This spectrum is generally considered to be a shared spectrum, that is, as long as communication equipment in different communication systems meets the regulatory requirements set by the country or region on the spectrum, they can use the spectrum without applying for exclusive spectrum authorization from the government.

[0041] In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist in a friendly manner on the spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, communication equipment follows the "Listen Before Talk (LBT)" principle, that is, before a communication device sends a signal on a channel of the unlicensed spectrum, it needs to first perform channel sensing. Only when the channel sensing result is that the channel is idle can the communication device send a signal; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send a signal. In order to ensure fairness, in one transmission, the duration of the communication device using the channel of the unlicensed spectrum for signal transmission cannot exceed the Maximum Channel Occupancy Time (MCOT).

[0042] However, in the New Radio Unliecensed (NR-U) system, when using unlicensed frequency bands for information transmission, due to the restriction on occupied bandwidth (OCB), comb interlace is required for frequency domain mapping of information transmitted on PUCCH.

[0043] When using each interlace for mapping, the information to be transmitted on the PUCCH needs to be mapped according to the mapping rules specified by the interlace. Figure 2 As shown, each bit in the information to be transmitted X(k) is mapped every 4 physical resource blocks on the physical resource blocks allocated by the PUCCH, thereby obtaining the mapping result of the transmission data X(k), and then the mapping result is sent out through the physical resource blocks allocated by the PUCCH.

[0044] In addition, in order to improve the utilization rate of the frequency domain resources of interlace, when the format of PUCC is Format 2, the PUCCH under Format 2 is also referred to as PF2 in this application. When using interlace, the physical resource blocks (PRBs) on the frequency domain resources corresponding to the interlace can also be multiplexed through OCC to increase the number of user multiplexing.

[0045] However, when the number of user multiplexing is increased, there will be too much duplication of information transmitted on the PUCCH, resulting in a high PAPR problem, which affects the information transmission process on the PUCCH.

[0046] Figure 3 A flowchart of an information transmission method provided in an embodiment of the present application. The method includes but is not limited to the following steps:

[0047] 301: When the configuration of the physical uplink control channel PUCCH meets a preset condition, the user terminal scrambles the information to be transmitted on the PUCCH.

[0048] The format of the PUCCH is Format 2.

[0049] The scrambling code is essentially to use a scrambling code sequence (random sequence) to perform a product operation with the information to be transmitted, so as to reduce the probability of data duplication in the information to be transmitted.

[0050] The configuration of PUCCH is configured by the network equipment, and the configuration of PUCCH includes but is not limited to one or a combination of the following: interlace, the number of interlaces, the orthogonal code length OCC-Length, the number of symbols used Nrof Symbols, and the like.

[0051] Optionally, the preset condition may include one or a combination of the above configurations. For example, the preset condition may be that interlace is configured for PUCCH and / or that the OCC-Length configured for PUCCH is greater than 1. The preset condition may also be that the number of interlaces used is greater than a first threshold and / or that Nrof Symbols is greater than a second threshold. The present application does not limit the specific form of the preset condition.

[0052] 302: The user terminal maps the scrambling result to the frequency domain resources corresponding to the PUCCH.

[0053] It can be seen that in an embodiment of the present application, when the configuration of the PUCCH in the format of Format2 meets the conditions, the information to be transmitted on the PUCCH is scrambled to avoid excessive duplication of content after the information to be transmitted is mapped to the frequency domain resources, thereby reducing the peak-to-average power ratio and improving data transmission efficiency.

[0054] Figure 4 A flow chart of another information transmission method provided in an embodiment of the present application. Figure 3 The same contents as those in the embodiments shown are not described again here. The method includes but is not limited to the following steps:

[0055] 401: When the configuration of the physical uplink control channel PUCCH meets the preset condition, the user terminal modulates the target sequence using a preset modulation method to obtain a scrambling code sequence.

[0056] The target sequence may be a target bit sequence, and the target sequence may be obtained by processing the initial parameters using a binary random generator, that is, a random binary sequence is generated using the binary random generator and the initial parameters, and the binary sequence is used as the target sequence.

[0057] The preset modulation mode includes binary phase shift keying (BPSK) or quadrature phase shift keying (QPSK).

[0058] For example, when the target sequence is (0, 1, 0, 0, 1, 1), if the preset modulation mode is BPSK modulation, the obtained scrambling code sequence is (-1, 1, -1, -1, 1, 1); if the preset modulation mode is QPSK, the obtained scrambling code sequence is ((-1+j) / sqrt(2), (1+j) / sqrt(2), (1-j) / sqrt(2)).

[0059] Furthermore, the initial parameter is obtained through a preset function, and the variables of the preset function include a scrambling identity.

[0060] It should be noted that the scrambling identity is not the only independent variable of the preset function, and other variables may also be set in the preset function; in addition, the preset function may contain more than one item of the scrambling identity, and this application does not limit this.

[0061] For example, the preset function may be: Init seed = a*scrambling identity + b, where a and b are preset parameter values, and Init seed is an initial parameter; the preset function may also be: Init seed = a*scrambling identity -1 +b*scrambling identity -2 +c, where scrambling identity-1 is the first scrambling identity and scrambling identity-2 is the second scrambling identity. -1 Can be Cell Identity, scrambling identity -2 It can be a configuration value. It is understandable that when a scrambling identity has no corresponding value, the value of the scrambling identity can be set to zero.

[0062] The scrambling code index includes one or a combination of a cell identity (Cell Identity) of a serving cell, a configuration value, and a preset value (a value pre-set in a protocol).

[0063] Specifically, any one of the Cell Identity, configuration value, and preset value can be used as the scrambling identity; the average of two of the Cell Identity, configuration value, and preset value can be used as the scrambling identity; of course, the two values ​​can be combined to obtain a final value, which is used as the scrambling identity; similarly, the Cell Identity, configuration value, and preset value can be used as the scrambling identity at the same time, or the three values ​​can be combined to obtain a final value, which is used as the scrambling identity.

[0064] For example, if the Cell Identity is 6, the configuration value is 8, and the preset value is 10. When the preset function includes a scrambling identity item, any one of the three values ​​can be taken as the value of the scrambling identity; or the average of the two values ​​(such as 7 or 9) can be taken as the value of the scrambling identity; or, two initial parameters corresponding to the two values ​​can be obtained in sequence through the preset function, and then the two initial parameters are weighted to obtain the above-mentioned initial parameters. The average value of the three values, 8, can be taken as the value of the scrambling identity; or, three initial parameters corresponding to the three values ​​can be obtained in sequence through the preset function, and then the three initial parameter values ​​are processed (such as weighted) to obtain the above-mentioned initial parameters.

[0065] Optionally, the Cell Identity can be obtained through a synchronization signal block (Synchronization Signal and PBCH block, SSB), that is, when accessing a service cell, the SSB sent by the service cell is received, and the SSB is parsed to obtain the Cell Identity of the service cell.

[0066] Optionally, the above configuration value is indicated by user equipment specific radio resource control (UE-specific RRC) configuration information.

[0067] Optionally, the UE-specific RRC configuration information includes an uplink control channel configuration information source PUCCH-Config Information Element, a physical uplink control channel resource information source PUCCH-Resource IE, and a PUCCH-Format2 IE.

[0068] Refer to Table 1, Table 2 and Table 3. Table 1 and Table 2 show two configuration forms of PUCCH-Resource IE; Table 3 shows the configuration form of PUCCH-Format2 IE.

[0069] As shown in Table 1, the Scrambling Identity is configured in the PUCCH-Resource IE (also referred to as IE: PUCCH-Resource), and the format of the PUCCH is also configured as format 2; As shown in Table 2, in the PUCCH-Resource IE, it is possible to configure whether scrambling is required, the Scrambling Identity required for scrambling, and the format of the PUCCH is format 2.

[0070] Therefore, the configuration value and the configuration of PUCCH can be indicated by PUCCH-Config IE; or, indicated by PUCCH-Resource IE; or, indicated by PUCCH-Format2 IE. That is, the configuration value is read in the relevant field of each information source to obtain the Scrambling Identtty.

[0071] The configuration of the PUCCH-Config IE may be the same as or different from the above configuration method, and the present application does not limit the configuration form of the PUCCH-Config IE.

[0072] IE: PUCCH-Resource SEQUENCE occ-Length ENUM ERATED{n1,n2,n4} occ-Index INTEGER(1..16) Scrambling Identity INTEGER(0..1023) format Choice{format 2} …… ……

[0073] IE: PUCCH-Resource SEQUENCE occ-Length ENUM ERATED{n1,n2,n4} occ-Index INTEGER(1..16) Is scrambling required? {enable} Scrambling Identity INTEGER(0..1023) format Choice{format 2} …… ……

[0074] IE: PUCCH-Format2 SEQUENCE occ-Length ENUM ERATED{n1,n2,n4} occ-Index INTEGER(1..16) Interlace number {n1, n2} Scrambling Identity INTEGER(0..1023) Nrof Symbols INTEGER(1..2) Starting SymbolIndex INTEGER(0..13) …… ……

[0075] Optionally, the above-mentioned service cell is a cell accessed by the user terminal, and the service cell includes a primary service cell (Primary Cell, PCell) and / or a secondary service cell (Secondary Cell, SCell).

[0076] 402: The user terminal scrambles the information to be transmitted on the PUCCH using a scrambling sequence.

[0077] like Figure 5As shown, the information to be transmitted X(k) is scrambled using the scrambling sequence R(k), that is, the scrambling sequence R(k) is multiplied with the corresponding bits of the information to be transmitted X(k) to obtain the scrambling result Y(k).

[0078] 403: The user terminal maps the scrambling result to the frequency domain resources corresponding to the PUCCH.

[0079] It can be seen that in an embodiment of the present application, when the configuration of PUCCH meets the preset conditions, a scrambling sequence is used to scramble the information to be transmitted on the PUCCH, thereby reducing the repeated information after the information to be transmitted is mapped to the frequency domain resources, thereby reducing the peak-to-average power ratio and improving data transmission efficiency.

[0080] Figure 6 Another information transmission method provided in the embodiment of the present application. Figure 3 , Figure 4 The same contents as those in the embodiments shown are not described again here. The method includes but is not limited to the following steps:

[0081] 601: When the configuration of the physical uplink control channel PUCCH meets a preset condition, the user terminal modulates the target sequence using a preset modulation method to obtain a scrambling code sequence.

[0082] 602: The user terminal scrambles the information to be transmitted on the PUCCH using a scrambling sequence.

[0083] 603: The user terminal maps the scrambling result to the frequency domain resources corresponding to the PUCCH.

[0084] 604: The user terminal sends the mapping result to the network device through the frequency domain resources.

[0085] Furthermore, after receiving the mapping result, the network device descrambles the mapping result to obtain the information to be transmitted.

[0086] Specifically, the network device demaps the mapping result to obtain the scrambling result; then, the network device and the user terminal have the same random binary generator and preset function, and when the user terminal sends the mapping result, the scrambling index and the preset modulation mode can be synchronously reported to the network device. The network device can generate the same initial parameters through the preset function, and similarly, use the random binary generator to process the initial parameters to generate the above-mentioned scrambling sequence, and use the preset modulation mode and the scrambling sequence to obtain the target sequence. Finally, the target sequence is used to descramble the scrambling result to obtain the information to be transmitted.

[0087] It can be seen that in the embodiment of the present application, in the embodiment of the present application, when the configuration of PUCCH meets the preset conditions, a scrambling code sequence is used to encode the information to be transmitted on the PUCCH, thereby reducing the repeated information after the information to be transmitted is mapped to the frequency domain resources, thereby reducing the peak-to-average power ratio and improving data transmission efficiency.
