Fidelity, WiFi), fifth-generation communication (5th-Generation, 5G) system, B5G (Beyound5G) system, sixth-generation communication (6G) system or other communication systems, etc.

[0037] 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 (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, or vehicle-to-everything (V2X) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0038] The communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, and a standalone (SA) networking scenario.

[0039] The communication system in the embodiment of the present application can be applied to an unlicensed spectrum, where the unlicensed spectrum can also be considered as a shared spectrum; or, the communication system in the embodiment of the present application can also be applied to an authorized spectrum, where the authorized spectrum can also be considered as an unshared spectrum.

[0040] The embodiments of the present application can be applied to both non-terrestrial networks (NTN) and terrestrial networks (TN). NTNs generally use satellite communications to provide communication services to terrestrial users. Currently, NTN systems include NR-NTN and IoT-NTN systems, and may include other NTN systems in the future.

[0041] For example, Figure 1 is a schematic diagram of the architecture of a communication system provided by this application. As shown in Figure 1, communication system 100 may include network device 110, which may be a device that communicates with terminal device 120. Network device 110 may provide communication coverage for a specific geographic area and may communicate with terminal devices located within the coverage area.

[0042] Figure 1 exemplarily shows a network device 110 and two terminal devices 120. In some embodiments of the present application, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0043] For example, FIG2 is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG2 , the communication system may include a terminal device 201 and a satellite 202, and wireless communication may be performed between the terminal device 201 and the satellite 202. The network formed between the terminal device 201 and the satellite 202 may also be referred to as an NTN. In the architecture of the communication system shown in FIG2 , the satellite 202 may have the function of a base station, and the terminal device 201 and the satellite 202 may communicate directly. In this system architecture, the satellite 202 may be referred to as a network device. In some embodiments of the present application, the communication system may include multiple satellites 202, and each network satellite 202 may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0044] For example, FIG3 is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG3 , the communication system includes a terminal device 301, a satellite 302, and a base station 303. Wireless communication can be performed between the terminal device 301 and the satellite 302, and communication can be performed between the satellite 302 and the base station 303. The network formed between the terminal device 301, the satellite 302, and the base station 303 can also be referred to as an NTN. In the architecture of the communication system shown in FIG3 , the satellite 302 may not have the function of a base station, and the communication between the terminal device 301 and the base station 303 needs to be transferred through the satellite 302. Under this system architecture, the base station 303 can be referred to as a network device. In some embodiments of the present application, the communication system may include multiple base stations 303, each base station 303 may communicate with one or more satellites 302, and each satellite 302 may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0045] In future evolved communication systems such as B5G (Beyond 5G) or 6G, distributed multiple-input multiple-output (Distributed MIMO, also known as distributed antenna system) scenarios and / or massive multiple-input multiple-output (Massive MIMO, also known as massive antenna matrix system) scenarios may also be included. In some cases, Distributed MIMO and / or Massive MIMO can also support cell-free or terminal-centric (UE-centric) network deployment scenarios. It should be understood that the above scenarios are also applicable to TN and / or NTN.

[0046] The terminal devices mentioned in the embodiments of the present application may refer to UE (User Equipment), access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, user agent or user device. Optionally, the terminal device 10 may also be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5GS (5th Generation System) or a terminal device in a future evolved PLMN (Public Land Mobile Network), etc., and the embodiments of the present application are not limited to this. For convenience of description, the above-mentioned devices are collectively referred to as terminal devices. In the embodiments of the present application, "terminal device" and "UE" are often used interchangeably, but those skilled in the art will understand that the two can express the same meaning.

[0047] The network equipment mentioned in the embodiments of the present application may be an access network device, which may be located on the ground or on a satellite. An access network device is a device deployed in an access network to provide wireless communication functions for terminal devices. Access network devices may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in a 5G NR system, they are called gNodeB or gNB. With the evolution of communication technology, the name "access network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for terminal devices are collectively referred to as access network devices. Optionally, a communication relationship can be established between a terminal device and a core network device through the access network device.

[0048] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, subsequent evolution systems of 5G NR systems (e.g., B5G systems, 6G systems), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, and this application does not limit this.

[0049] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0050] For downlink data transmission, communication systems generally support the following two methods: 1. Dynamic scheduling; 2. Semi-persistent scheduling.

[0051] 1. Dynamic Scheduling

[0052] Dynamic scheduling refers to the way in which network equipment schedules downlink data transmission through downlink control signaling (Downlink Control Information, DCI). The terminal device receives the downlink control signaling sent by the network device, and then receives the downlink data based on the parameters in the downlink control signaling. The advantage of dynamic scheduling is that the scheduler determines the transmission parameters based on the real-time traffic volume and physical channel conditions, and the transmission efficiency is high. The terminal device first receives the downlink control signaling, and then receives the downlink data channel or sends the uplink data channel based on the parameters indicated in the downlink control signaling. However, the terminal device performs blind detection on the downlink control signaling, and its reception complexity is high. In addition, the processing delay of the terminal device includes two parts: the delay for demodulating the downlink control signaling and the delay for demodulating the downlink data.

[0053] 2. Semi-persistent scheduling (SPS)

[0054] Semi-persistent scheduling refers to a method by which network devices schedule downlink data transmission through high-level signaling (such as Radio Resource Control (RRC) signaling). The terminal device receives high-level signaling (such as RRC signaling) sent by the network device and receives downlink data based on the parameters in the high-level signaling. For scenarios with periodic arrival, constant traffic volume, and stable transmission conditions (for example, the terminal device does not move rapidly), using semi-persistent scheduling can reduce the downlink control signaling overhead in the system and simplify the reception processing of the terminal device.

[0055] With the development of communication technology, for example, in some applications of 6G URLLC (Ultra Reliable Low Latency Communication), the data has a relatively clear periodic arrival characteristic, but the amount of data transmitted in a single time is large, or the dynamic range of the data volume is large (that is, the amount of data to be transmitted in different periods varies greatly), or the transmission channel changes greatly. For this type of application, if the existing semi-continuous scheduling is used, since the transmission parameters are semi-statically configured, in order to ensure the transmission performance in the worst case, the configuration will be relatively conservative, so its transmission efficiency is not high. On the other hand, if the existing dynamic scheduling is used, the terminal device needs to receive the downlink control signaling before receiving the downlink data. The delay cannot be further reduced, and the periodic characteristics of the service are not fully utilized. The terminal device is still required to blindly detect the downlink control channel, resulting in waste of terminal power consumption.

[0056] Based on this, the present application provides a solution. For a first channel that is periodically transmitted, a first message is sent to a terminal device to indicate the type of information carried in the first channel, so that the network device can flexibly decide the type of information to be transmitted using the first channel based on information such as the characteristics of the currently transmitted service and channel conditions. Furthermore, the network device notifies the terminal device of the type of information carried in the first channel through the first message, so that the terminal device can obtain the type of information that the network device is about to transmit in the first channel based on the first message, thereby helping to improve the reliability of information transmission and reception efficiency.

[0057] Please refer to Figure 4, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The method may include the following steps:

[0058] In step 410, the terminal device receives first information, where the first information is used to indicate the type of information carried in a first channel, and the first channel is a periodically transmitted channel.

[0059] In some embodiments, the first information is sent by a network device. For example, the network device sends the first information, and the terminal device receives the first information accordingly. For example, the network device sends the first information to the terminal device, and the terminal device receives the first information from the network device accordingly.

[0060] In some embodiments, the first channel is a periodically transmitted channel. Periodic transmission refers to a channel that transmits periodically at regular intervals. For example, if the period is 1 second, the first channel transmits once every 1 second. For example, if the period is 2 time slots, the first channel transmits once every 2 time slots. This application does not limit the transmission period of the first channel.

[0061] In some embodiments, the first channel may be a control channel or a data channel. For example, the first channel may be a control channel used for downlink transmission, such as a PDCCH (Physical Downlink Control Channel). For example, the first channel may also be a data channel used for downlink transmission, such as a PDSCH (Physical Downlink Shared Channel). Of course, as communication technology evolves, the control channel or data channel may also be referred to by other names, and this application does not limit this.

[0062] In some embodiments, information can be divided into the following two types: data information and signaling information. Data information can be expressed in the form of a TB (Transport Block), a PDU (Protocol Data Unit), etc. Signaling information can be expressed in the form of DCI, configuration information, grant information, allocation information, etc. Compared to data information, signaling information has a smaller number of bits.

[0063] In an embodiment of the present application, for the first channel that is sent periodically, the network device can flexibly decide the type of information to be transmitted using the first channel based on information such as the service characteristics of the current transmission and the channel conditions. For example, when the channel conditions change slightly and the amount of data is constant, the periodic first channel is used to transmit data information; for another example, when the channel conditions change greatly or the amount of data changes greatly, the periodic first channel is used to transmit signaling information. In addition, the network device informs the terminal device of the type of information carried in the first channel through the first information, so that the terminal device can learn the type of information that the network device is about to transmit in the first channel based on the first information, thereby helping to improve the reliability of information transmission and reception efficiency.

[0064] In some embodiments, the first information is used to indicate the type of information carried in the first channel, and the type of information includes at least one of the following: data information and signaling information. The first information can indicate the following three situations: (1) the first information is used to indicate that the first channel carries data information, or in other words, the first information is used to indicate that the first channel only carries data information; (2) the first information is used to indicate that the first channel carries signaling information, or in other words, the first information is used to indicate that the first channel only carries signaling information; (3) the first information is used to indicate that the first channel carries data information and signaling information, or in other words, the first information is used to indicate that the first channel carries both data information and signaling information.

[0065] In some embodiments, for the above situations (1) and (3), if the data information has corresponding check information, the check information corresponding to the data information is also carried in the first channel. In some embodiments, for the above situations (2) and (3), if the signaling information has corresponding check information, the check information corresponding to the signaling information is also carried in the first channel. In some embodiments, the type of check information includes one or more of the following: Cyclic Redundancy Check (CRC), Error Correction Code (ECC), Checksum, Parity Check, etc., which are not limited in this application.

[0066] Because signaling information has a smaller number of bits than data information, when the content carried in the periodically transmitted first channel consists solely of signaling information, the communication system only needs to semi-statically reserve resources for the signaling information, while data information can be dynamically adjusted based on actual transmission conditions, thereby helping to improve system efficiency. Furthermore, by extending the semi-static scheduling transmission mechanism to signaling information transmission, terminal devices no longer need to perform complex blind detection of control signaling, which does not increase terminal device implementation complexity and saves terminal device power consumption.

[0067] In some embodiments, the first information is used to indicate the type of information carried in the first channel, and the type of information includes one of the following: signaling information and no signaling information. The first information can indicate the following two situations: (1) the first information is used to indicate that the information carried in the first channel includes signaling information; (2) the first information is used to indicate that the information carried in the first channel does not include signaling information.

[0068] In some embodiments, for the above situation (1), the presence of signaling information indicates that the content carried by the first channel includes signaling information and may or may not include data information. In other words, if the first information indicates that the type of information carried in the first channel is signaling information, then the information carried in the first channel must include signaling information, but the first information does not explicitly indicate whether the information carried in the first channel also includes data information.

[0069] In some embodiments, for the above situation (2), the absence of signaling information indicates that the content carried by the first channel does not include signaling information, which can also be understood as the content carried by the first channel only includes data information.

[0070] In some embodiments, when the first information indicates that the type of information carried in the first channel is signaling information, the terminal device determines, based on the first information, whether the information carried in the first channel also includes data information. In some embodiments, if the first information includes parameters of the data information, the terminal device determines that the information carried in the first channel also includes data information; if the first information does not include parameters of the data information or lacks some parameters of the data information, the terminal device determines that the information carried in the first channel does not include data information. In some embodiments, the parameters of the above-mentioned data information include but are not limited to at least one of the following: time domain resources of the data information, frequency domain resources of the data information, coding level of the data information, HARQ (Hybrid Automatic Repeat reQuest) process information corresponding to the data information, etc.

[0071] In the above manner, the first information is used to indicate whether the type of information carried in the first channel is signaling information or non-signaling information. There are only two indication results, which can save the signaling overhead of the first information.

[0072] In some embodiments, the first information is used to indicate the type of information carried in the first channel, and the type of information includes one of the following: data information and no data information. The first information can indicate the following two situations: (1) the first information is used to indicate that the information carried in the first channel includes data information; (2) the first information is used to indicate that the information carried in the first channel does not include data information.

[0073] In some embodiments, for the above situation (1), the presence of data information indicates that the content carried by the first channel includes data information, and may or may not include signaling information. In other words, if the first information indicates that the type of information carried by the first channel is data information, then the information carried by the first channel must include data information, but the first information does not explicitly indicate whether the information carried by the first channel also includes signaling information.

[0074] In some embodiments, for the above situation (2), no data information indicates that the content carried by the first channel does not include data information, which can also be understood as the content carried by the first channel only includes signaling information.

[0075] In some embodiments, when the first information indicates that the type of information carried in the first channel is data information, the terminal device determines, based on the first information, whether the information carried in the first channel also includes signaling information. In some embodiments, if the first information includes parameters of the signaling information, the terminal device determines that the information carried in the first channel also includes signaling information; if the first information does not include parameters of the signaling information or lacks some parameters of the signaling information, the terminal device determines that the information carried in the first channel does not include signaling information. In some embodiments, the parameters of the signaling information include, but are not limited to, at least one of the following: the type of signaling information, the encoding method of the signaling information, the format of the signaling information, the protocol version number corresponding to the signaling information, etc.

[0076] In the above manner, the first information is used to indicate whether the type of information carried in the first channel is data information or no data information. There are only two indication results, which can save the signaling overhead of the first information.

[0077] In the following, for the case where the information carried in the first channel includes signaling information, the signaling information is described.

[0078] In some embodiments, when the information carried in the first channel includes signaling information, the signaling information is used to indicate parameters of the second channel. The second channel is another channel different from the first channel.

[0079] In some embodiments, the second channel may include a control channel and / or a data channel, and the control channel may include a control channel for downlink transmission and / or a control channel for uplink transmission, and the data channel may include a data channel for downlink transmission and / or a data channel for uplink transmission. Exemplarily, the second channel includes one or more of the following types of channels: PUSCH (Physical Uplink Shared Channel), PDSCH, PUCCH (Physical Uplink Control Channel), PDCCH. Of course, with the evolution of communication technology, the control channel or data channel may also be called by other names, which is not limited in this application.

[0080] In some embodiments, the time domain position of the second channel is after the time domain position of the first channel; or, the time domain position of the second channel is no earlier than the time domain position of the first channel. The time domain refers to the time domain. The time domain resources of a channel refer to the time allocated for use by the channel within the time domain. The time domain position of a channel refers to the position in the time domain of the time period between the start and end of signal transmission on the channel.

[0081] In some embodiments, the time domain position of the second channel is after the time domain position of the first channel, which means that the starting time domain position of the second channel is after the starting time domain position of the first channel. In this case, the time domain resources occupied by the second channel may overlap with the time domain resources occupied by the first channel.

[0082] In some embodiments, the time domain position of the second channel is after the time domain position of the first channel, which means that the starting time domain position of the second channel is after the ending time domain position of the first channel. In this case, the time domain resources occupied by the second channel must not overlap with the time domain resources occupied by the first channel.

[0083] In some embodiments, the time domain position of the second channel is no earlier than the time domain position of the first channel, which means that the starting time domain position of the second channel is no earlier than the starting time domain position of the first channel. In this case, the time domain resources occupied by the second channel may overlap with the time domain resources occupied by the first channel.

[0084] In some embodiments, the time domain position of the second channel is no earlier than the time domain position of the first channel, which means that the starting time domain position of the second channel is no earlier than the ending time domain position of the first channel. In this case, the time domain resources occupied by the second channel and the time domain resources occupied by the first channel either do not overlap, or overlap only at the ending time domain position of the first channel when the starting time domain position of the second channel and the ending time domain position of the first channel are the same.

[0085] In addition, since the first channel is a periodically transmitted channel, the above-mentioned comparison of the time domain positions of the first channel and the second channel refers to the case where the information carried in a certain first channel includes signaling information, and the time domain position comparison between the first channel carrying the signaling information and the second channel indicated by the signaling information.

[0086] For example, as shown in Figure 5, it shows a schematic diagram of the time domain positions of the first channel and the second channel provided by an embodiment of the present application. The parameters of the second channel A are indicated by the signaling information A transmitted by the first channel at time domain positions a to b, and the parameters of the second channel B are indicated by the signaling information B transmitted by the first channel at time domain positions e to f. The starting time domain position of the second channel A is c, and the ending time domain position is d. The starting time domain position of the second channel A is after the ending time domain position b of the first channel where the signaling information A is located. The starting time domain position of the second channel B is g, and the ending time domain position is h. The starting time domain position of the second channel B is after the ending time domain position f of the first channel where the signaling information B is located.

[0087] In addition, the second channel may include one channel or multiple channels (or a group of channels).

[0088] In some embodiments, the second channel includes at least one of the following: at least one downlink channel, at least one uplink channel. In some embodiments, the second channel includes channels in the following three situations:

[0089] (1) The second channel includes at least one downlink channel;

[0090] (2) The second channel includes at least one uplink channel;

[0091] (3) The second channel includes at least one downlink channel and at least one uplink channel.

[0092] Among them, the downlink channel can be a control channel used for downlink transmission (such as PDCCH) or a data channel used for downlink transmission (such as PDSCH); the uplink channel can be a control channel used for uplink transmission (such as PUCCH) or a data channel used for uplink transmission (such as PUSCH).

[0093] Through the above method, the control information carried in the periodically sent first channel can schedule uplink transmission and / or downlink transmission. The specific channel type and number indicated can be determined according to actual transmission requirements, and this application does not limit this.

[0094] In some embodiments, the parameters of the second channel include at least one of the following: frequency domain resource information of the second channel, time domain resource information of the second channel, modulation and coding information corresponding to the second channel, HARQ process information corresponding to the second channel, redundant version information corresponding to the second channel, precoding related information corresponding to the second channel, reference signal information corresponding to the second channel, power control information corresponding to the second channel, transmission resource information of feedback information corresponding to the second channel, and priority information of the second channel.

[0095] The frequency domain resource information of the second channel is used to indicate the frequency domain resources allocated to the second channel. Exemplarily, the frequency domain resources may be a frequency band, a frequency band, a subcarrier, a BWP (Bandwidth Part), a grid, a bandwidth, an RB (Resource Block), an RBG (Resource Block Group), etc.

[0096] The time domain resource information of the second channel is used to indicate the time domain resources allocated to the second channel. Exemplarily, the time domain resources may be a frame, a subframe, a time slot, a sub-time slot, a symbol, a CP (Cyclic Prefix), a cycle, and the like.

[0097] The modulation and coding information corresponding to the second channel indicates the modulation and coding method used for information transmission on the second channel. Modulation methods include, but are not limited to, amplitude modulation, frequency modulation, and phase modulation. Coding methods include, but are not limited to, forward error correction coding, interleaved coding, and multiple access codes. In the embodiments of this application, the specific modulation and coding methods are not limited.

[0098] The HARQ process information corresponding to the second channel is used to indicate information such as the number and status of the HARQ process corresponding to the information transmitted by the second channel.

[0099] The redundancy version information corresponding to the second channel is used to indicate the redundancy version (RV) corresponding to the second channel. The RV is designed to implement incremental redundancy (IR) HARQ transmission. This involves dividing the redundant bits generated by the encoder into several groups. Each RV defines a transmission starting point. Different RVs are used for the initial transmission and each HARQ retransmission to achieve the gradual accumulation of redundant bits and complete the incremental redundancy HARQ operation.

[0100] The precoding related information corresponding to the second channel is used to indicate a precoding method for information transmitted on the second channel. The precoding method includes but is not limited to at least one of the following: linear precoding, nonlinear precoding, codebook-based precoding, non-codebook precoding, etc.

[0101] The reference signal information corresponding to the second channel is used to indicate relevant information of the reference signal corresponding to the second channel. A reference signal is a known signal provided by a transmitting end to a receiving end for channel estimation or channel detection, and is divided into an uplink reference signal and a downlink reference signal.

[0102] The power control information corresponding to the second channel is used to indicate the power when transmitting information on the second channel. The power control information may include open-loop power control information and / or closed-loop power control information.

[0103] The transmission resource information of the feedback information corresponding to the second channel is used to indicate the transmission resources occupied by the HARQ feedback information corresponding to the second channel.

[0104] The priority information of the second channel is used to indicate the priority of the second channel among the multiple channels.

[0105] The terminal device can receive the second channel based on the above parameters of the second channel indicated by the received control information, thereby improving the reliability and success rate of the second channel reception.

[0106] In some embodiments, the signaling information includes parameters of the second channel. That is, the signaling information directly indicates the parameters of the second channel. The terminal device can directly obtain the parameters of the second channel from the signaling information. This approach provides greater flexibility in indicating the parameters of the second channel.

[0107] In some embodiments, the signaling information includes an offset value or a differential value of the parameters of the second channel. The terminal device obtains the offset value or the differential value of the parameters of the second channel from the signaling information, and then determines the parameters of the second channel in combination with a pre-set reference configuration. In some embodiments, the reference configuration is indicated by at least one of the following information: first information, other information other than the first information. Among them, the other information other than the first information may be high-level signaling or downlink control information. Exemplarily, the signaling information indicates that the modulation and coding level corresponding to the second channel is the offset value delta, and the reference modulation and coding level of the second channel is A, then the modulation and coding level of the second channel is A+delta. In the above manner, the signaling information only needs to include the offset value or the differential value of the parameters of the second channel, and the bit overhead of the signaling information is relatively small.

[0108] In some embodiments, the first channel may carry at least one piece of signaling information, each piece of signaling information being used to indicate parameters of one or more second channels. Exemplarily, each piece of signaling information is used to indicate parameters of multiple second channels. For example, when the multiple second channels are periodic, the parameters of the multiple second channels may be multiplexed and transmitted in the same piece of signaling information. Multiplexing the parameters of multiple second channels in the same piece of signaling information helps reduce signaling overhead, improve system efficiency, and reduce the number of detections performed by terminal devices, thereby reducing power consumption of the terminal devices.

[0109] In some embodiments, when multiple pieces of signaling information are carried on a first channel, the multiple pieces of signaling information are independently encoded. When the multiple pieces of signaling information are independently encoded, the encoded pieces of signaling information are mapped to the first channel for transmission, such as by concatenation. Because different pieces of signaling information have different reliability requirements, independent encoding can improve efficiency. However, if each piece of signaling information is equipped with an independent checksum, this increases the signaling information overhead.

[0110] In some embodiments, when multiple pieces of signaling information are carried in the first channel, the multiple pieces of signaling information are jointly encoded. When multiple pieces of signaling information are jointly encoded, the jointly encoded signaling information is mapped to the first channel for transmission. Joint encoding methods include, but are not limited to, time domain joint encoding, frequency domain joint encoding, spatial domain joint encoding, and concatenated encoding. Since multiple pieces of signaling information are jointly encoded, the overhead of the check code is relatively low, thereby reducing the total overhead. However, if some bits are erroneous during transmission, all signaling information may not be properly received.

[0111] In some embodiments, when the information carried in the first channel includes signaling information, the first information is also used to indicate at least one of the following information: signaling format, signaling content, bit size of the signaling, modulation and coding level corresponding to the signaling, and coding rate corresponding to the signaling.

[0112] The signaling format indicates the order and structure of signaling information and is specified by the communication technology and protocols. Signaling content is the information in the signaling information used to control and manage the communication process, such as information on establishing and releasing connections, network configuration information, and protocol information. The bit size of the signaling indicates the length of the signaling information, i.e., the number of bits it occupies. The modulation and coding level of the signaling indicates the MCS (Modulation and Coding Scheme) used for the signaling information. The coding rate of the signaling indicates the bit rate used to transmit the signaling information; different signaling methods can use different coding rates.

[0113] By using the above method, the relevant information of the indication signaling information is clearly indicated, which is helpful to avoid blind detection at the receiving end.

[0114] In some embodiments, when the information carried in the first channel includes signaling information, the encoding method of the signaling information is determined based on the protocol agreed information or indicated by the first information.

[0115] In some embodiments, the protocol agreement information is used to agree on an encoding method for signaling information. In some embodiments, the protocol agreement information is also used to agree on a bit size constraint for the signaling information. The bit size constraint for the signaling information may include: the bit size of the signaling information is greater than or equal to a first value, and / or less than or equal to a second value.

[0116] In some embodiments, if the bit size of the valid information in the signaling information is less than the first value, placeholder information (padding) is added to the signaling information so that the bit size of the signaling information after the placeholder information is added is equal to the first value, thereby satisfying the above-mentioned restriction. Placeholder information refers to a field or value in the signaling information that does not carry useful information, and can be represented in at least one of the following forms: a zero value, a special flag bit, etc. Exemplarily, if the first value is 4 and the bit size of the valid information in the signaling information is 2 bits, then 4-2=2 bits of placeholder information are added to the signaling information, and the bit size of the resulting signaling information is 4 bits, which is equal to the first value.

[0117] In some embodiments, if the bit size of the valid information in the signaling information is greater than the second value, the signaling information is divided into at least two parts, the bit size of each part meets the above-mentioned agreed conditions, each part is independently encoded, and each part is independently encoded and carried together in the first channel for transmission. In some embodiments, if the bit size of one of the at least two parts is less than the first value, placeholder information can be added to the part to meet the above-mentioned agreed conditions. For example, the first value is 2, the second value is 11, the bit size of the valid information of the signaling information is 13 bits, and the signaling information is divided into The bit sizes of the information in the two parts are Bit and bit.

[0118] In the above manner, signaling information adopts a fixed coding method, which is relatively simple to implement. However, the overhead of signaling information may be increased due to the placeholder information, thereby reducing system efficiency.

[0119] In some embodiments, the protocol agreement information is used to agree on the correspondence between the bit size of the signaling information and the encoding method of the signaling information, and the encoding method of the signaling information is determined according to the bit size of the signaling information and the correspondence.

[0120] In some embodiments, the above correspondence is determined based on a bit size interval, with multiple bit size intervals being provided, and a corresponding encoding scheme being provided for each bit size interval. Optionally, different bit size intervals may correspond to different encoding schemes. Encoding schemes for signaling information include, but are not limited to, repetition coding, block coding, RM (Reed-Muller) coding, Polar codes, low-density parity-check (LDPC) codes, convolutional codes, and Turbo codes.

[0121] Exemplarily, when the bit size of the signaling information falls within a first bit size interval, a first encoding method is used; when the bit size of the signaling information falls within a second bit size interval, a second encoding method is used. The first bit size interval and the second bit size interval are different, and the first encoding method and the second encoding method are different. There can be multiple bit size intervals, and different intervals can correspond to different encoding methods or the same encoding method.

[0122] Exemplarily, when the bit size of the signaling information is less than or equal to 2, the signaling information uses a repetition coding method; when the bit size of the signaling information is greater than 2 but less than or equal to 11, the signaling information uses a group coding method or an RM coding method; when the bit size of the signaling information is greater than 12 and less than or equal to 140, the signaling information uses a Polar coding method; when the bit size of the signaling information is greater than 140, the signaling information uses an LDPC coding method.

[0123] Exemplarily, when the bit size of the signaling information is less than or equal to 2, the signaling information uses a repetition coding method; when the bit size of the signaling information is greater than 2 but less than or equal to 11, the signaling information uses a block coding method or an RM coding method; when the bit size of the signaling information is greater than 12 and less than or equal to 140, the signaling information uses the first Polar coding method; when the bit size of the signaling information is greater than 140 and less than or equal to 1706, the signaling information uses the second Polar coding method; when the bit size of the signaling information is greater than 1706, the signaling information uses an LDPC coding method.

[0124] The encoding methods corresponding to different intervals can be configured according to the requirements of information transmission, and this application does not limit this.

[0125] By configuring different coding modes for signaling information of different bit sizes in the above manner, the coding gain can be maximized.

[0126] In some embodiments, when the information carried on the first channel includes signaling information and data information, the signaling information and the data information are independently encoded. In some embodiments, the independently encoded signaling information and the independently encoded data information are concatenated and mapped to the first channel for transmission. This independent encoding allows the data information and signaling information to meet their respective reliability requirements, thereby improving system efficiency.

[0127] In some embodiments, the transmission resource of the first channel is indicated by the first information. The transmission resource of the first channel refers to the resources used to transmit information on the first channel, including one or more of the following resources: time domain resources, frequency domain resources, spatial domain resources, code domain resources, etc.

[0128] In some embodiments, when the information carried in the first channel includes signaling information and data information, the first channel occupies a first resource, the second resource occupied by the signaling information in the first resource is determined according to an agreed rule, and the third resource occupied by the data information is the remaining resource in the first resource excluding the second resource. The first resource occupied by the first channel can be pre-configured or indicated, such as by the first information or other information.

[0129] In some embodiments, when the information carried in the first channel includes signaling information and data information, the first channel occupies the first resource, the third resource occupied by the data information in the first resource is determined according to an agreed rule, and the second resource occupied by the signaling information is the remaining resource in the first resource excluding the third resource. The first resource occupied by the first channel can be pre-configured or indicated, such as by the first information or other information.

[0130] In some embodiments, the above-mentioned agreed rules can be indicated by the first information or agreed upon by the agreement, and this application does not limit this.

[0131] In the above manner, the resources occupied by the first channel, the resources occupied by data information, and the resources occupied by signaling information are determined according to the agreed rules, which helps to reduce the overhead for configuring the first channel.

[0132] In some embodiments, the agreed rules are related to at least one of the following factors: coding rate information of signaling information, resource occupancy ratio of signaling information, maximum resource occupancy of signaling information, priority of signaling information, coding rate information of data information, resource occupancy ratio of data information, maximum resource occupancy of data information, and priority of data information.

[0133] The coding rate information of signaling information is information used to indicate the bit rate when transmitting signaling information. The resource occupancy ratio of signaling information refers to the ratio of resources occupied by signaling information in the first resource of the first channel. The maximum resource occupancy amount of signaling information refers to the maximum amount of resources occupied by signaling information in the first resource of the first channel. The priority of signaling information is used to indicate the importance or urgency of transmitting signaling information in the first channel. The coding rate information of data information is information used to indicate the bit rate when transmitting data information. The resource occupancy ratio of data information refers to the ratio of resources occupied by data information in the first resource of the first channel. The maximum resource occupancy amount of data information refers to the maximum amount of resources occupied by data information in the first resource of the first channel. The priority of data information is used to indicate the importance or urgency of transmitting data information in the first channel.

[0134] In the above manner, according to the agreed rules and relevant factors of signaling information and data information, and based on the resources configured for the first channel, the resources occupied by the signaling information and the resources occupied by the data information are reasonably allocated.

[0135] In some embodiments, when the information carried on the first channel includes signaling information and data information, the second resource occupied by the signaling information and the third resource occupied by the data information are configured or indicated through the first information or other information. The first resource occupied by the first channel is equal to the second resource occupied by the signaling information plus the third resource occupied by the data information. This approach achieves precise configuration and improves channel utilization.

[0136] In some embodiments, the second resource occupied by the signaling information includes one of the following: at least one time domain symbol, at least one frequency domain resource unit, and at least one resource element (RE).

[0137] A time domain symbol refers to a basic unit of time used to transmit information, and may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol or other symbol. For example, data information and signaling information are transmitted in a time division multiplexing manner in the first channel, occupying different time domain symbols.

[0138] A frequency domain resource unit (FRU) is a basic unit used to allocate and manage spectrum resources. For example, in a 5G NR system, the entire spectrum is divided into multiple FRUs, each corresponding to a subcarrier or resource block. For example, signaling information and data information are transmitted in the first channel using frequency division multiplexing, occupying different FRUs.

[0139] A resource element is the smallest resource unit of physical resources used for channel transmission. For example, a resource element is a symbol in the time domain and a subcarrier in the frequency domain.

[0140] In some embodiments, the first channel is a downlink channel, i.e., the first channel is a periodically transmitted downlink channel. In some embodiments, the first channel is a PDSCH, i.e., the first channel is a periodically transmitted PDSCH. A periodically transmitted downlink channel refers to a downlink channel that transmits information at regular time intervals. In some embodiments, the periodically transmitted downlink channel may be a semi-persistently scheduled physical downlink shared control channel (SPS PDSCH), or may be another downlink channel that can be used for periodic transmission.

[0141] In some embodiments, the first information includes at least one of the following information: high-layer signaling, downlink control signaling, and activation signaling.
