Description

Communication method, device and system

Technical Field

The present invention relates to the field of wireless communications, and in particular, to a communication method, apparatus, and system in a wireless communication system.

Background

In the random access scheme of the existing long term evolution system (Long Term Evolution, LTE), the random access procedure of the user equipment (UserEquipment, UE) is initiated by the higher layer or medium access control (Media Access Control, MAC) layer. When the UE is in uplink out-of-step, the random access procedure is referred to as an asynchronous random access procedure, and one common method in the asynchronous random access procedure is contention-based random access, which is as follows: the UE sends a random access sequence message Msg1 to the base station through a random access channel (Random Access Channel, RACH), the base station feeds back a random access response message Msg2 to the UE through a downlink shared channel (Downlink Shared Channel, DL-SCH), then the UE sends a first scheduling message Msg3 to the base station through an uplink shared channel (Uplink Shared Channel, UL-SCH), and the base station returns a contention resolution content message Msg4 to the UE. After receiving the Msg4 of the downlink transmission of the base station, the UE needs to send a hybrid automatic repeat request (Hybrid Automatic repeat request, HARQ) feedback message to the base station if the contention is successful, otherwise, the base station cannot perform subsequent data transmission. And the UE determines the resource carrying the feedback message through the index of the control channel unit in the downlink control channel carrying the Msg4.

In a New Radio (NR) system, when a terminal device is in an initial access phase, information interaction with a network side device is required, and finally the terminal device feeds back response information of successful access to the network side device to complete Radio Resource Control (RRC) connection. In the NR system, how to flexibly and efficiently perform resource allocation to implement RRC connection between the terminal device and the network device is a technical problem to be solved.

Detailed Description

The network architecture and the service scenario described in the embodiments of the present invention are for more clearly describing the technical solution of the embodiments of the present invention, and do not constitute a limitation on the technical solution provided by the embodiments of the present invention, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present invention is applicable to similar technical problems.

In the embodiments of the present invention, "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Fig. 1 shows a schematic diagram of a possible application scenario in an embodiment of the present invention. The communication system in the application scene comprises: a network device, and one or more terminal devices. Wherein the network device and the terminal device may communicate via one or more air interface technologies.

Hereinafter, terms that may appear in the embodiments of the present invention will be explained.

Communication system: it may be applied to a long term evolution (Long Term Evolution, abbreviated as LTE) system, or other wireless communication systems employing various wireless access technologies, such as a system employing access technologies such as code division multiple access, frequency division multiple access, time division multiple access, orthogonal frequency division multiple access, single carrier frequency division multiple access, etc. In addition, the method can be also suitable for subsequent evolution systems using the LTE system, such as a fifth generation 5G system and the like.

Network equipment: may be a base station or an access point or may refer to a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals. The network device may be configured to inter-convert the received air frames with IP packets as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) network. The network device may also coordinate attribute management for the air interface. For example, the network device may be a base station (Base Transceiver Station, BTS) in global mobile communications (Global System of Mobile communication, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a base station (NodeB, NB) in wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), an evolved base station (Evolutional Node B, eNB or eNodeB) in long term evolution (Long Term Evolution, LTE), or a relay station or access point, or a base station in future 5G networks, such as a gNB, etc., without limitation. It should be noted that, for a 5G or NR system, there may be one or more transmission and reception points (Transmission Reception Point, TRP) under one NR base station, where all the TRPs belong to the same cell, and each TRP and terminal may use the measurement reporting method described in the embodiments of the present application. In another scenario, the network device may be further divided into a Control Unit (CU) and a Data Unit (DU), and under one CU, there may be a plurality of DUs, where each DU and the terminal may use the measurement reporting method described in the embodiments of the present application. The CU-DU split scenario differs from the multi-TRP scenario in that TRP is just one radio frequency unit or one antenna device, whereas protocol stack functions may be implemented in DUs, e.g. physical layer functions may be implemented in DUs.

Terminal equipment: either a wireless terminal, which may be a device that provides voice and/or other traffic data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. The wireless terminals may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), which may be mobile terminals such as mobile phones (or "cellular" phones) and computers with mobile terminals, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access network. Such as personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiation Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDAs), and the like. A wireless Terminal may also be referred to as a system, subscriber Unit (Subscriber Unit), subscriber Station (Subscriber Station), mobile Station (Mobile Station), mobile Station (Mobile), remote Station (Remote Station), remote Terminal (Remote Terminal), access Terminal (Access Terminal), user Terminal (User Terminal), user Agent (User Agent), user equipment (User Device or User Equipment), without limitation.

Symbols, including but not limited to orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols, sparse code division multiple access (Sparse Code Multiplexing Access, SCMA) symbols, filtered orthogonal frequency division multiplexing (Filtered Orthogonal Frequency Division Multiplexing, F-OFDM) symbols, non-orthogonal multiple access (Non-Orthogonal Multiple Access, NOMA) symbols, may be specifically determined according to practical situations, and will not be described herein.

Sub-frames: one subframe occupies time-frequency resources of the entire system bandwidth in the frequency domain and occupies a fixed time length, e.g., 1 millisecond (ms), in the time domain. At the same time, one subframe can occupy continuous K symbols, wherein K is a natural number larger than zero. The value of K may be determined according to practical situations, and is not limited herein. For example, in LTE, 1 subframe occupies 14 consecutive OFDM symbols in the time domain.

Time slots: the time slot refers to a basic time domain resource unit, occupies L continuous OFDM symbols in the time domain, and L is a natural number greater than zero. The value of L may be determined according to practical situations, for example, 7 OFDM symbols.

Physical resource block (Physical Resource Block, PRB): a frequency domain resource unit occupies M continuous subcarriers in a frequency domain, wherein M is a natural number larger than zero. For example, M is equal to 12 or 16.

Subcarrier width: spacing of center frequencies of adjacent subcarriers. For example, the subcarrier width of 1 subcarrier may be 15×2 ⁿ kHZ, where n is a non-negative integer.

High layer signaling: separate from the physical layer signaling, it may be a master information block (Master Information Block, MIB), a system information block (System Information Block, SIB), or radio resource control (Radio Resource Control, RRC) signaling, or other higher layer signaling with similar characteristics.

Response information: or feedback information, which may include, but is not limited to, hybrid automatic repeat request (HARQ, hybrid Automatic Repeat Request) techniques. The HARQ technique is a technique in which forward error correction coding (Forward Error Correction, FEC) and automatic repeat request (Automatic Repeat Request, ARQ) are combined.

For example, in the HARQ technique, a receiving end may determine whether information is accurately decoded after receiving the information from a transmitting end. If the decoding can be performed accurately, the receiving end may feed back Acknowledgement (ACK) information to the transmitting end, so that the transmitting end may determine that the receiving end receives the information accurately based on the ACK information.

Further optionally, if the decoding cannot be accurately performed, the receiving end may feed back non-acknowledgement (NACK) information to the transmitting end, so that the transmitting end may determine that the receiving end does not accurately receive the information based on the NACK information.

That is, in the embodiment of the present invention, ACK information may be sent to the transmitting end when the receiving end decodes successfully. Alternatively, NACK information may be fed back to the transmitting end when decoding fails.

It should be understood that the contents included in the response information or the feedback information listed above are only exemplary, and the present invention is not limited thereto, and other information capable of indicating the receiving condition of the terminal device on the downlink information falls within the protection scope of the present invention.

Bandwidth region: a plurality of physical resource blocks, which are contiguous in the frequency domain, are typically configured by a network device for a terminal device. The terminal device receives or transmits data within the BWP. Taking control resource transmission as an example, at least one control resource set is included in one BWP, and the frequency domain resources included in the control resource set do not exceed a plurality of physical resource blocks included in the BWP on the frequency domain. In addition, the area where the terminal device interacts with the network device in the initial access phase may be referred to as an initial active bandwidth area (Initial active BWP), and may be, for example, initial Uplink (UL) BWP and/or initial Downlink (DL) BWP.

Frequency hopping: frequency hopping, a transmission mode. For example, for an uplink control channel occupying 2T symbols (or, a set of resources for carrying the uplink control channel includes 2T symbols), the first T consecutive time domain symbols (the first subset, or, the first hopping unit) are transmitted on one frequency domain resource, and the last T consecutive time domain symbols (the second subset, or, the second hopping unit) are transmitted on another frequency domain resource. By using a frequency hopping transmission mode, the transmission of the uplink control channel can acquire the frequency diversity gain and improve the transmission performance of the uplink control channel.

Further, a possible schematic structure of the above network device may be shown in fig. 2. The network device 102 is capable of performing the methods provided by embodiments of the present invention. Wherein the network device 102 may comprise: a controller or processor 201 (hereinafter processor 201 is illustrated as an example) and a transceiver 202. The controller/processor 201 is sometimes referred to as a modem processor (modem processor). Modem processor 201 may include a baseband processor (baseband processor, BBP) (not shown) that processes the digitized received signal to extract the information or data bits conveyed in the signal. As such, the BBP is typically implemented in one or more digital signal processors (digital signal processor, DSP) within the modem processor 201 or as separate integrated circuits (integrated circuit, IC) as needed or desired.

Transceiver 202 may be used to support the transceiving of information between a network device and a terminal device, as well as to support the radio communication between terminal devices. The processor 201 may also be used to perform the functions of various terminal devices communicating with other network devices. On the uplink, uplink signals from the terminal device are received via the antenna, mediated by the transceiver 202, and further processed by the processor 201 to recover traffic data and/or signaling information transmitted by the terminal device. On the downlink, traffic data and/or signaling messages are processed by the terminal device and modulated by transceiver 202 to generate a downlink signal, which is transmitted via an antenna to the terminal device. The network device may also include a memory 203 that may be used to store program codes and/or data for the network device. The transceiver 202 may include separate receiver and transmitter circuits, or may be the same circuit to perform the transceiving functions. The network device may further comprise a communication unit 204 for supporting the network device to communicate with other network entities. For example, for supporting the communication between the network device and a network device of a core network or the like.

Optionally, the network device may also include a bus. The transceiver 202, the memory 203, and the communication unit 204 may be connected to the processor 201 through a bus. For example, the bus may be a peripheral component interconnect standard (Peripheral Component Interconnect, PCI) bus or an extended industry standard architecture (Extended Industry Standard Architecture, EISA) bus, or the like. The buses may include an address bus, a data bus, a control bus, and the like.

Fig. 3 is a schematic diagram of a possible configuration of a terminal device in the communication system. The terminal equipment can execute the method provided by the embodiment of the invention. The terminal device may be any one of the one or more terminal devices in fig. 1. The terminal device comprises a transceiver 301, an application processor (application processor) 302, a memory 303 and a modem processor (modem processor) 304.

Transceiver 301 may condition (e.g., analog convert, filter, amplify, upconvert, etc.) the output samples and generate an uplink signal, which is transmitted via an antenna to a base station as described in the above embodiments. On the downlink, an antenna receives downlink signals transmitted by the network device. Transceiver 301 may condition (e.g., filter, amplify, downconvert, digitize, etc.) the received signal from the antenna and provide input samples.

Modem processor 304, also sometimes referred to as a controller or processor, may include a baseband processor (baseband processor, BBP) (not shown) that processes the digitized received signal to extract the information or data bits conveyed in the signal. BBP is typically implemented in one or more digits within modem processor 304 or as a separate Integrated Circuit (IC) as needed or desired.

In one design, a modem processor 304 may include an encoder 3041, a modulator 3042, a decoder 3043, and a demodulator 3044. The encoder 3041 is used for encoding a signal to be transmitted. For example, the encoder 3041 may be configured to receive traffic data and/or signaling messages to be transmitted on the uplink and process (e.g., format, encode, interleave, etc.) the traffic data and signaling messages. The modulator 3042 is used to modulate the output signal of the encoder 3041. For example, the modulator may perform symbol mapping and/or modulation, etc., on the output signal (data and/or signaling) of the encoder and provide output samples. The demodulator 3044 is configured to perform demodulation processing on an input signal. For example, a demodulator 3044 processes the input samples and provides symbol estimates. The decoder 3043 is used for decoding the demodulated input signal. For example, the decoder 3043 deinterleaves, decodes, and/or the like the demodulated input signal, and outputs a decoded signal (data and/or signaling). The encoder 3041, modulator 3042, demodulator 3044 and decoder 3043 may be implemented by a composite modem processor 304. These units are handled according to the radio access technology employed by the radio access network.

Modem processor 304 receives digitized data, which may represent voice, data, or control information, from application processor 302 and processes the digitized data for transmission. The modem processor may support one or more of a variety of wireless communication protocols for a variety of communication systems, such as LTE, new air interface, universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS), high speed packet access (High Speed Packet Access, HSPA), and so forth. Optionally, one or more memories may be included in modem processor 304.

Alternatively, the modem processor 304 and the application processor 302 may be integrated in one processor chip.

The memory 303 is used to store program code (sometimes also referred to as programs, instructions, software, etc.) and/or data for supporting communication with the terminal device.

It should be noted that the memory 203 or the memory 303 may include one or more storage units, for example, may be a storage unit inside the processor 201 or the modem processor 304 or the application processor 302 for storing program codes, or may be an external storage unit independent of the processor 201 or the modem processor 304 or the application processor 302, or may also be a component including a storage unit inside the processor 201 or the modem processor 304 or the application processor 302 and an external storage unit independent of the processor 201 or the modem processor 304 or the application processor 302.

The processor 201 and the modem processor 304 (hereinafter referred to as processor 304) may be the same type of processor or different types of processors. For example, the logic may be implemented in a central processing unit (Central Processing Unit, CPU), general purpose processor, digital signal processor (Digital Signal Processor, DSP), application-specific integrated circuit (ASIC), field programmable gate array (Field Programmable Gate Array, FPGA) or other programmable logic device, transistor logic device, hardware component, other integrated circuit, or any combination thereof. The processor 201 and modem processor 304 may implement or execute the various exemplary logic blocks, modules and circuits described in connection with the present disclosure. The processor may also be a combination of devices implementing computing functions, e.g., including one or more microprocessor combinations, a combination of a DSP and a microprocessor, or a system-on-a-chip (SOC), etc.

Those of skill in the art will appreciate that the various illustrative logical blocks, modules, circuits, and algorithms described in connection with the aspects disclosed herein may be implemented as electronic hardware, instructions stored in memory or in another computer readable medium and executed by a processor or other processing device, or combinations of both. As an example, the apparatus described herein may be used in any circuit, hardware component, IC, or IC chip. The memory disclosed herein may be any type and size of memory and may be configured to store any type of information as desired. To clearly illustrate this interchangeability, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. How such functionality is implemented depends upon the particular application, design choice, and/or design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.

In the embodiment of the present invention, transmitting the downlink (uplink) channel may refer to transmitting data or information carried on the downlink (uplink) channel, where the data or information may refer to data or information after channel coding.

Embodiments of the present invention will be described in further detail below based on the above-described common aspects of the present invention. In the explanation of the embodiment, the time delay possibly existing between the uplink and the downlink is ignored, and the transmission time of the network device is assumed to be the same as the reception time of the terminal device. For the processing corresponding to the transmission of the network device and the reception of the terminal device, in the embodiment, the angle is described from the side of the terminal device, and those skilled in the art will understand that the terminal device receives from the network device, which means that the network device transmits. The present invention relates to the expression "resource set", which is a combination of resources logically as will be understood by a person skilled in the art.

In the embodiment of the present invention, sending the uplink control channel may refer to sending data or information carried on the uplink control channel, where the data or information may refer to data or information after channel coding.

In the embodiment of the present invention, each resource set may be preconfigured (or, in other words, statically or semi-statically configured), that is, a higher-level management device of the communication system divides and notifies each network device, or, a division manner of each resource set may be specified by a communication protocol, or, a division manner of each resource set is prestored in each network device by a factory setting or an administrator setting, or the like. For example, for the same resource, each network device may use the resource in a time division multiplexing manner, and a specific corresponding time usage range may be divided by a higher layer management device. Alternatively, each set of resources may be autonomously determined (or, alternatively, dynamically changing) by each network device.

The expressions "first", "second", and the like mentioned in the embodiments of the present invention are not limited to the order or the number, and may be any one.

In the NR system, when the terminal equipment is in an initial access stage, the terminal equipment and the network equipment need to complete information interaction. Specifically, the terminal device needs to send preamble information (also called Msg 1) to the network device, initiate an access request to the network device, and then the network device feeds back configuration information to the terminal device that initiates the access request at the same time through the broadcasted RAR information (also called Msg 2). After receiving the Msg2, the terminal equipment receives a downlink scheduling signaling sent by the network equipment through a downlink control channel, after receiving the downlink scheduling signaling, the terminal equipment sends Msg3 through an uplink data channel to report relevant information of the terminal equipment, the network equipment identifies the terminal equipment through the Msg3, and configures the relevant information to the appointed terminal equipment through unicast Msg4 information to finish confirmation of conflict resolution and RRC configuration. After receiving the Msg4, the terminal device needs to feed back response information to the network device, and completes the RRC connection process by means of handshake communication.

It should be noted here that, generally, after the terminal device completes RRC connection, the terminal device feedback response information configures a physical uplink control channel resource set (PUCCH resource set) through radio resource control RRC signaling, and then dynamically indicates one PUCCH resource in the PUCCH resource set for the terminal device feedback response information through downlink control information (Downlink Control Information, DCI). However, in the initial access phase, the network device cannot configure PUCCH resource set for the terminal device through RRC signaling, so that it is required to configure PUCCH resource sets for feeding back response information of Msg4 for the terminal device in the initial access state through broadcasting system information (for example, SIB 1).

Currently, the system information 1 (System Information Broadcast 1, sib1) contains only 4 bits of fields for configuring the PUCCH resource set, and the independent indication of each PUCCH resource through RRC signaling causes a significant overhead. Therefore, how to configure a PUCCH resource set for a terminal device with such limited 4-bit information and further efficiently indicate PUCCH resources for feeding back response information of Msg4 becomes a problem to be solved.

For convenience of explanation, in the embodiment of the present invention, an uplink resource with a time domain length of L symbols is referred to as an uplink resource of L symbols.

Embodiments of the present invention will be described in further detail below based on the above-described common aspects of the present invention.

Fig. 4 shows a specific implementation of the communication method in the embodiment of the present invention, and the scheme provided by the embodiment of the present invention is described below according to fig. 4.

Step 400: the network device sends first indication information to the terminal device, wherein the first indication information is used for determining a first resource set or a second resource set in a plurality of Physical Uplink Control Channel (PUCCH) resource sets, at least one resource set in the plurality of PUCCH resource sets comprises at least two uplink resources, and the time domain lengths of the at least two uplink resources are different.

Specifically, the uplink resource in the PUCCH resource set is used for the terminal device to feed back the response information, for example, one uplink resource is used for one terminal device to feed back the HARQ-ACK. The PUCCH uplink resources include resources of a time domain, a frequency domain, and/or a code domain. Optionally, the time domain resource includes the number of symbols occupied by the resource and the index of the occupied symbol in 1 slot; the frequency domain resources include an index of physical resource blocks, PRBs, in an initial active bandwidth region (initial active BWP). The code domain resources include time domain orthogonal cover codes OCC and cyclic shift CS values.

Optionally, the first indication information includes N bits, where N is a positive integer. For example, N is 4, the first indication information is used to indicate a first resource set of the maximum 16 resource sets.

Optionally, each of the plurality of PUCCH resource sets may include R PUCCH resources, where R is a positive integer. For example, R is 4 or 8.

Wherein at least one resource set in the plurality of PUCCH resource sets includes at least two uplink resources, and time domain lengths of the at least two uplink resources are different. The different time domain lengths may also be divided into a plurality of time domain length types. For example, the time domain length may be 14 symbols, 10 symbols, 2 symbols, and 1 symbol. Wherein, 14 symbols and 10 symbols are called a first time domain length type (also called a long PUCCH resource), and 2 symbols and 1 symbol are called a second time domain length type (also called a short PUCCH resource). For another example, the plurality of PUCCH resource sets includes one resource set including 2 uplink resources of time domain length, 10 symbols and 14 symbols, or 10 symbols and 2 symbols, etc.

By including uplink resources with various time domain lengths in one resource set, the PUCCH resource set can be flexibly adapted to various Slot types. Wherein, 1-symbol and 2-symbol PUCCHs can be transmitted in slots for uplink (UL only), the above center of behavior (UL center) or the below center of behavior (DL center), 14-symbol PUCCHs can be transmitted in UL only slots, and 10-symbol PUCCHs can be transmitted in UL only and UL center slots. If the semi-statically configured PUCCH resource set only contains a 14-symbol long PUCCH resource configuration, HARQ-ACK information can only be fed back on the UL only slot, which may cause an increase in delay of access of the terminal device. But if the PUCCH resources of 1 symbol and 14 symbols are configured at the same time, the network device can configure the terminal device to feed back HARQ-ACK information on more kinds of slots, and if the coverage of the terminal device is limited, can also configure the PUCCH feedback HARQ-ACK of 14 symbols for enhancing the coverage.

Optionally, the first indication information is carried in system information, for example, system information transmitted through a broadcast channel, such as SIB1, RMSI, etc. Or, the first indication information is indicated by downlink control information DCI or higher layer signaling.

This step may be performed by the transceiver 202 of the network device or by the processor 201 controlling the transceiver 202.

Step 401: the terminal equipment acquires first indication information; for example 1101.

Alternatively, the correspondence between the first indication information and the configuration of the first resource set may be reflected in a tabular manner. As described in table 1. Here, in table 1, there are a plurality of items of information, and the first indication information indicates index information of the first column. One or more items of information shown in the first row in the table 1 may be acquired through the first indication information. The embodiments of the present invention are described in relation to the association between the first indication information and the other pieces of information in table 1 and the preset rule that is satisfied, and it is not necessary to determine the pieces of information in table 1 according to the association and the rule.

In table 1, the first action header information, the index is bit information corresponding to the first indication information, and the PUCCH Format is a Format adopted by an uplink resource in the resource set indicated by the first indication information, for example, format 0 or 1; the number of resource symbols is the number of symbols included in the uplink resource in the resource set indicated by the first indication information, or the time domain length of the uplink resource may include, for example, 1 symbol, 2 symbols, 10 symbols, and/or 14 symbols of uplink resource, for example, the resource set corresponding to 1101 includes 10 symbols, 14 symbols, and 1 symbol of uplink resource; the initial symbol indicates that the initial symbol of the uplink resource in the resource set indicated by the first indication information occupies an index of a symbol in the current time slot, for example, the resource set indicated by 0001 in table 1 includes an uplink resource of 1 symbol, and the initial symbol of the uplink resource of 1 symbol is a symbol with an index of 13 in the current time slot; for another example, the resource set indicated by 0100 includes 14 symbols and 1 symbol uplink resources, where a start symbol of the 14 symbols uplink resources is a symbol with an index of 0 in the current slot, and a start symbol of the 1 symbols uplink resources is a symbol with an index of 13 in the current slot. The PRBs in the initial uplink BWP are configured as frequency domain resources occupied by uplink resources in the resource set indicated by the first indication information, for example, in the resource set indicated by 0111, the frequency domain of the uplink resources of 14 symbols occupies resource blocks with indexes of PRB 1 and PRB L-1 in the initial UL BWP, and the frequency domain of the uplink resources of 1 symbol occupies resource blocks with indexes of PRB 1 and PRB L-2 in the initial UL BWP, where L is the number of PRBs in the initial UL BWP. The initial Cyclic Shift (CS) index is an initial Cyclic Shift index of an uplink resource or an interval of an initial Cyclic Shift index between uplink resources in the resource set indicated by the first indication information. Time domain OCC is a time domain orthogonal cover code, and OCC of uplink resources of 14 symbol length in the resource set indicated by 0100 in table 1 is 0.

TABLE 1

Step 402: and the terminal equipment sends response information to the network equipment through a first uplink resource, wherein the first uplink resource belongs to the first resource set or the second resource set.

The steps 401 and 402 may be performed by the transceiver 301 of the terminal device or by the processor 304 controlling the transceiver 301.

In a first implementation, the first uplink resource is an uplink resource in a first resource set in the plurality of physical uplink control channel PUCCH resource sets.

In the first implementation, the terminal device determines a first uplink resource in a first resource set indicated by the first indication information, so as to send response information.

In a second implementation, the first uplink resource is an uplink resource in the second resource set.

The second resource set is determined by the terminal equipment according to the first indication information and the second indication information, and the second indication information is used for indicating the scheduling type of the first signaling and/or the second signaling. Optionally, the first signaling is uplink signaling Msg3, and the second signaling is downlink signaling Msg2. Alternatively, the second indication information may include two independent indication information, where the two independent indication information indicates scheduling types of the first signaling and the second signaling, respectively.

Optionally, the second indication information is downlink control information.

In this second implementation, the terminal device further determines, through the scheduling types of the first signaling and/or the second signaling, a second resource set, and determines a first uplink resource in the second resource set, so that the configuration of the uplink resource is more dynamic and flexible.

Further optionally, the second set of resources may or may not belong to the plurality of PUCCH resource sets.

By the communication method implemented in steps 400-402 described above, an efficient indication of PUCCH resources in a communication system may be achieved.

Optionally, the step 402 further includes:

step 4011, the network equipment sends third indication information to the terminal equipment; the third indication information is used for indicating at least one uplink resource in the first resource set or the second resource set. For example, the third indication information includes N ₁ A number of bits, said being N ₁ A positive integer. For example, N ₁ Is 2 or 3.

Optionally, the third indication information is carried in downlink control information or is carried in system information, for example, system information transmitted through a broadcast channel, such as SIB1, RMSI, etc.; or, alternatively, by higher layer signaling.

Step 4012, the terminal equipment obtains third indication information, and determines at least one uplink resource according to the third indication information and one resource set of the first or second resource sets.

Optionally, if the third indication information indicates one uplink resource, the third indication information is used to indicate the first uplink resource in the first or second resource set. In this alternative, theNamely, what is calledThe N is ₁ One bit is sufficient to indicate one uplink resource. Wherein the N is ₁ The bits can be carried in the downlink control information, and further, N in continuous or discontinuous positions in the downlink control information ₁ A number of bits.

For example, r=4, n ₁ When=2, thenThen N ₁ One bit is sufficient to indicate one of the R resources.

Optionally, the third indication information indicates more than one uplink resource in the first or second resource set, and the first uplink resource is determined by the third indication information and a value of Z, where the value of Z is equal to (c+s (i)) mod 2; "mod" means a modulo (or, alternatively, a remainder) operation; wherein C is 0, or C is a minimum index value or a maximum index value of a control channel element CCE occupied by a downlink control channel used to carry the third indication information, S (i) is a pseudo random sequence, i is a non-negative integer, or i is a parameter required for generating the pseudo random sequence. In this alternative, the Namely the N ₁ The number of bits is insufficient for indicating one uplink resource and for indicating a subset, i.e. more than one uplink resource, of said first or second set of resources. Then it is required at this time at said N ₁ The first uplink resource is determined from a subset of the bit indications.

For example, r=8, n ₁ When=2, thenThen N ₁ One bit is not sufficient to indicate one of the R resources. Alternatively, N ₁ Each of the bits is used to indicate only a subset of the R resources, e.g., 2 of the R resources. In this case, the terminal device may determine the first uplink resource in the subset, where the first uplink resource passes through the third indication messageInformation and a value of Z equal to

(c+s (i)) mod 2, where Z is 0, the first uplink resource may be one of the 2 resources, and where Z is 1, the first uplink resource may be another of the 2 resources.

Further optionally, the pseudo-random sequence is an m sequence or a gold sequence. The initial value of the pseudo-random sequence is determined by a cell radio network temporary identity (Cell Radio Network Temporary Identifier, C-RNTI) or a terminal device identity, e.g. UE-ID.

In an alternative design, the first set of resources or the second set of resources includes at least two uplink resources, and the time domain lengths of the at least two uplink resources are different, where:

optionally, if the time domain length types of the at least two uplink resources are the same, the number of the at least two uplink resources is the same.

Optionally, if the time domain length types of the at least two uplink resources are different, the number of uplink resources belonging to the first time domain length type in the at least two uplink resources is the same as the number of uplink resources belonging to the second time domain length type in the at least two uplink resources.

Specifically, if uplink resources of the first time domain length type and the second time domain length type exist in one PUCCH resource set at the same time, the number of the resources of the first time domain length type and the second time domain length type is the same; if only one time domain length type exists, the number of uplink resources with various time domain lengths belonging to the one time domain length type is the same.

For example, if the 1 resource set includes R PUCCH uplink resources, including long PUCCH resources and short PUCCH resources, the number of resources of both the long PUCCH and the short PUCCH is R/2.

For another example, if the 1 resource set includes R PUCCH uplink resources, and only the long PUCCH resources are included, the number of resources of the long PUCCH resources is R. Further, the number of resources of the long PUCCH resources is equally divided among the long PUCCHs of all time domain lengths, for example, the number of PUCCH resources of 10 symbols and 14 symbols is R/2, respectively.

Through the optional design, the time domain length of the PUCCH resource has a corresponding relation with the number of the PUCCH resources of each time domain length, and the number of the PUCCH resources of the corresponding time domain length can be determined according to the time domain length and/or the time domain length type of the PUCCH resources contained in the PUCCH resource set, so that the expenditure of configuration signaling is reduced.

In an alternative design, the frequency domain resources occupied by the uplink resources belonging to the first time domain length type and the second time domain length type in the first resource set or the second resource set do not overlap.

Optionally, the frequency domain resources occupied by the uplink resources belonging to the first time domain length type in the first resource set or the second resource set are frequency domain resources corresponding to the physical resource blocks with the largest and/or smallest index values in the initial active bandwidth area. For example, PRB 0 and PRB m-1, where m is the number of PRBs contained in the initial active BWP.

Through the optional design, the time domain length of the PUCCH resource has a corresponding relation with the frequency domain resource of the PUCCH resource of each time domain length, and the frequency domain resource occupied by the PUCCH resource of the corresponding time domain length can be determined according to the time domain length and/or the time domain length type of the PUCCH resource contained in the PUCCH resource set, so that the cost of configuration signaling is reduced.

In an alternative design, the initial cyclic shift index of the uplink resource in the first or second resource set satisfies: a+b is n, wherein a is an integer, b is in the range {1,2,3}, and n is an integer. The first or second resource set contains n resources, and the initial cyclic shift index of the n resources satisfies a+b×n. That is, an offset between an initial cyclic shift index of a previous resource and a subsequent resource among the n resources is b.

Optionally, the value of b is determined by one of:

first, when the uplink resource belongs to the first time domain length type, the value of b is 3, and when the uplink resource belongs to the second time domain length type, the value of b is 2 or 3. That is, the b value corresponding to the long PUCCH resource is 3, and the b value corresponding to the short PUCCH resource is one of 2 and 3.

Second, the value of b is indicated by 1 bit, and the 1 bit is included in the first indication information. For example, 1 bit of the N bits is used to indicate which of a plurality of values or which group of values is preconfigured for the value of b. Wherein the values of b corresponding to the resources of the first and second time domain length types may be referred to as a set of values, or the values of b corresponding to the resources of the plurality of different time domain lengths may be referred to as a set of values.

For example, the 1-bit information is used to determine that an interval of an initial cyclic shift index (initial index of CS) of PUCCH resources having the same time domain length is 1 or 2 or 3. The CSs of the plurality of PUCCH resources having the same time domain length are configured at equal intervals.

When a is 0, b is 1, the time domain length of the PUCCH resource is 10 symbols, and one resource set includes 4 PUCCH resources, the initial cyclic shift index of each PUCCH resource is 0,1,2,3;

when a is 0, b is 2, the time domain length of the PUCCH resource is 10 symbols, and one resource set includes 4 PUCCH resources, the initial cyclic shift index of each PUCCH resource is 0,2,4,6;

when a is 0, b is 3, the time domain length of the PUCCH resource is 10 symbols, and one resource set includes 4 PUCCH resources, the initial cyclic shift index of each resource is 0,3,6,9;

when a is 0, b is 1, the time domain length of the PUCCH resource is 1 symbol, and one resource set includes 4 PUCCH resources, the initial cyclic shift index of each resource is 0,1,2,3;

when a is 0, b is 2, the time domain length of the PUCCH resource is 1 symbol, and one resource set comprises 4 resources, the initial cyclic shift index of each resource is 0,2, and occupies 2 PRBs;

When a is 0, b is 3, the time domain length of the pucch resource is 1 symbol, and one resource set includes 4 resources, the initial cyclic shift index of each resource is 0,3, and occupies 2 PRBs.

By the implementation mode, the initial cyclic shift index interval is dynamically indicated by 1 bit, so that the signaling overhead can be further reduced, and the interference among multiple users can be reduced.

Third, the value of b corresponds to a time domain length or a time domain length type of the uplink resource, where, for uplink resources having the same time domain length or belonging to the same time domain length type in the first or second resource set, the value of b is the same.

Fourth, the value of b is preconfigured and may be 1, 2 or 3.

Through the first, third and fourth implementation manners, the initial cyclic shift index interval can be indirectly configured, and signaling overhead is reduced.

In an alternative design, the first indication information includes N bits, where the N bits conform to at least one of:

the value of a first bit of the N bits corresponds to whether the first set of resources includes or does not include uplink resources having a first time domain length;

The value of a second bit of the N bits corresponds to whether the first set of resources includes or does not include uplink resources having a second time domain length;

the value of a third bit of the N bits corresponds to the first set of resources including uplink resources having a third or fourth time domain length.

In a first implementation, the value of each bit of the N bits corresponds to whether the first set of resources includes or does not include uplink resources having a respective time domain length. Take the bitmap of n=4 in table 2 as an example. A is that ₀ -A ₃ Respectively represent corresponding bits, A ₀ Represents whether or not a 10-symbol PUCCH resource is included, A ₁ Represents whether or not a 14-symbol PUCCH resource is included, A ₂ Represents whether or not a 1 symbol-included PUCCH resource, a ₃ Representing whether a 2 symbol PUCCH resource is included.

TABLE 2

For example, A ₀ A ₁ A ₂ A ₃ 1111, a PUCCH uplink resource including 10 symbols, 14 symbols, 1 symbol, and 2 symbols in the first resource set is described.

And combining the above-mentioned optional designs related to the time domain length type of the uplink resources and the number of the uplink resources, wherein, optionally, the time domain length types of the at least two uplink resources are different, and the number of the uplink resources belonging to the first time domain length type in the at least two uplink resources is the same as the number of the uplink resources belonging to the second time domain length type in the at least two uplink resources. If the number of resources R included in the first resource set is 8, the number of resources included in the first resource set is 4, and the number of resources included in the first time domain length type (10 symbols and 14 symbols) is 4, and the number of resources included in the second time domain length type (1 symbol and 2 symbols) is 4. Further optionally, the time domain length types of the at least two uplink resources are the same, and the number of the at least two uplink resources is the same. The numbers of PUCCH resources of 10 symbols and 14 symbols in the first resource set are 2, and the numbers of PUCCH resources of 1 symbol and 2 symbol are also 2.

As another example, A ₀ A ₁ A ₂ A ₃ 1011, the PUCCH uplink resource containing 10 symbols, 1 symbol, and 2 symbols in the first resource set is described.

And combining the above-mentioned optional designs related to the time domain length type of the uplink resources and the number of the uplink resources, wherein, optionally, the time domain length types of the at least two uplink resources are different, and the number of the uplink resources belonging to the first time domain length type in the at least two uplink resources is the same as the number of the uplink resources belonging to the second time domain length type in the at least two uplink resources. If the number of resources R included in the first resource set is 8, the number of resources of the first time domain length type (10 symbols) is 4, and the number of resources of the second time domain length type (1 symbol and 2 symbols) is 4. Further optionally, the time domain length types of the at least two uplink resources are the same, and the number of the at least two uplink resources is the same. The number of PUCCH resources for 1 symbol and 2 symbols in the first resource set is 2.

In a second implementation, the value of at least one bit of the N bits corresponds to whether the first set of resources includes or does not include uplink resources having a respective time domain length. Take the bitmap of n=4 in table 3 as an example. A is that ₀ -A ₃ Respectively represent corresponding bits, A ₀ Represents whether or not a 10-symbol PUCCH resource is included, A ₁ A indicates whether or not PUCCH resources of 14 symbols are included ₂ PUCCH resource indicating whether 1 symbol or 2 symbols are included, A ₃ Index indicating initial cyclic shift initial value, or a ₃ Indicating the interval of the initial cyclic shift initial value.

TABLE 3 Table 3

For example, A ₀ A ₁ A ₂ A ₃ 1111, the first resource set includes PUCCH uplink resources of 10 symbols, 14 symbols, and 2 symbols, and the uplink resource of the corresponding time domain length uses an index corresponding to an initial cyclic shift with a bit value of 1.

Optional designs related to the number of uplink resources by combining the above-mentioned uplink resource time domain length types:

optionally, if the time domain length types of the at least two uplink resources are different, the number of uplink resources belonging to the first time domain length type in the at least two uplink resources is the same as the number of uplink resources belonging to the second time domain length type in the at least two uplink resources. If the number of resources R included in the first resource set is 8, the number of resources included in the first resource set is 4, and the number of resources included in the first time domain length type (10 symbols and 14 symbols) is 4. Further optionally, the time domain length types of the at least two uplink resources are the same, and the number of the at least two uplink resources is the same. The number of PUCCH resources of 10 symbols and 14 symbols in the first resource set is 2.

Optionally, the initial cyclic shift indexes of the two 10 symbol uplink resources are 0 and 3; the initial cyclic shift indexes of the two 14 symbol uplink resources are also 0 and 3, and the interval between the two is 3, namely b=3; the interval of the initial cyclic shift index between the 4 2-symbol uplink resources is also 3.

In an alternative design, orthogonal cover codes (Orthogonal Cover Code, OCC) for uplink resources in the first or second set of resources are pre-configured or defined; for example, any one or more of 0, 1, -1.

And the OCCs corresponding to the uplink resources with the same time domain length in the first resource set or the second resource set are the same.

For example, the corresponding relationship between the number of OCC symbols and OCC can be seen in table 4.

OCC symbol number	OCC
		2	[1 1]
3	[1 1 1]
		4	[11 1 1]
5	[1 1 1 1 1]
		6	[1 1 1 1 1 1]
7	[1 1 1 1 1 1 1]

TABLE 4 Table 4

For uplink control information UCI, the correspondence between the number of symbols of PUCCH uplink resource and OCC of UCI may be shown with reference to table 5. Table 5 contains the mapping relationship of OCC configuration and hopping configuration. As can be seen from table 5, for the uplink resource of 10 symbols, in the hopping scenario, UCI occupies 2 symbols in the first hopping unit and 3 symbols in the second hopping unit, and then, in combination with table 4, the OCC of UCI in the first hopping unit is [1,1], and the OCC in the second hopping unit is [1, 1]. For uplink resources of 14 symbols, UCI occupies 3 symbols in the first hopping unit and 4 symbols in the second hopping unit, and as can be seen from table 4, OCC of UCI in the first hopping unit is [1,1], and OCC of UCI in the second hopping unit is [1, 1].

TABLE 5

For the demodulation reference signal (Demodulation Reference Signal, DMRS), the correspondence relationship between the number of symbols of the PUCCH uplink resource and the OCC of the DMRS can be referred to as shown in table 6. As can be seen from table 6, for an uplink resource of 10 symbols, in a frequency hopping scenario, the DMRS occupies 3 symbols in the first frequency hopping unit and 2 symbols in the second frequency hopping unit, and in combination with table 4, it can be seen that in a frequency hopping scenario, the OCC of the DMRS in the first frequency hopping unit is [1,1], and the OCC in the second frequency hopping unit is [1,1]. For an uplink resource of 14 symbols, the OCC of the DMRS in the first hopping unit is [1,1], and the OCC in the second hopping unit is [1,1].

TABLE 6

In an alternative design, there is a correspondence between the first set of resources or the second set of resources and at least one Physical Random Access Channel (PRACH) resource, the correspondence being pre-configured. Optionally, the number of uplink resources contained in the first or second resource set is equal to the number of PRACH resources configured by the network device at the same time.

In the initial access phase, the network device may configure multiple PRACH resources, e.g., P, simultaneously. If multiple UEs access the cell at the same time, at most P users need to feed back the response information of Msg4 at the same time, if the number of PRACH resources exceeds the number of PUCCH resources in the PUCCH resource set, the users will collide when feeding back the response information, and multiple users feed back on one PUCCH resource at the same time. Through the association of the P PRACH resources to the first PUCCH resource set, the number of the PRACH resources which are dynamically configured can be associated with the number of uplink resources in the PUCCH resource set, the requirement on the number of the PUCCH uplink resources when more PRACH resources are configured can be adaptively met, and meanwhile, the requirement on PUCCH resource overhead can be reduced when fewer PRACH resources are configured.

It should be noted that, the determining operation of the network device according to the embodiment of the present invention may be performed by the processor 201, the transceiving operation of the network device may be performed by the transceiver 202, or the transceiver 202 may be controlled by the processor 201 to perform; the determining operation of the terminal device may be performed by the processor 304, the acquiring operation of the terminal device may be performed by the processor 304 or the transceiver 301, or the transceiver 301 may be controlled by the processor 304 to perform the transceiving operation of the terminal device, depending on the acquiring manner, may be performed by the transceiver 301.

The scheme provided by the embodiment of the invention is mainly introduced from the interaction angle among the network elements. It will be appreciated that each network element, e.g. UE, base station, core network entity, etc. in order to implement the above-mentioned functions, comprises corresponding hardware structures and/or software modules for performing each function. Those of skill in the art will readily appreciate that the various illustrative elements and algorithm steps described in connection with the embodiments disclosed herein may be implemented as hardware or combinations of hardware and computer software. Whether a function is implemented as hardware or computer software driven hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.

The following is further explained based on a possible structure of the terminal device in fig. 3. The terminal device can execute any method of the embodiment of the present invention, and the terminal device at least may include: transceiver 301, and processor 304 (referred to herein generically as a processor, may represent modem processor 304 itself, or an integration of modem 304 and application processor 302). Optionally, fig. 3, which may also include a memory or the like, and other components described in connection with fig. 3. The transceiver 301 may be composed of a separate receiver and transmitter, and may perform the corresponding receiving and transmitting functions separately, or may be a transceiver integrating the receiving and transmitting functions. And are not further limited herein. Structurally, the transceiver 301 in fig. 3 may be split into a receiver 301A and a transmitter 301B. Here, since the terminal device is only an exemplary description as an alternative subject, a wireless device, which may be a unit, chip, or part included in the terminal device, or the terminal device itself, will be described below as a subject.

The wireless device includes a processor 304 and a transmitter 301B; optionally, further comprising a receiver 301A, wherein:

In a first alternative design:
