[0110] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0111] In Long Term Evolution (LTE), the Control Region consists of the Physical Control Format Indicator channel (PCFICH), the Physical Hybrid ARQ Indicator channel (PHICH), the Physical Downlink Control Channel (PDCCH), and reference symbols. The mapping order is as follows: first map the reference symbols, then map the PCFICH and PHICH, and finally map the PDCCH.

[0112] Reference Symbols include downlink cell-specific reference signals that support cell communication, as well as primary synchronization signals (PSS) and search space sets (SSS) that support initial access synchronization of terminal devices. These signals are predefined by the protocol and configured at fixed time-frequency domain locations.

[0113] The PCFICH carries a 2-bit Control Format Indicator (CFI) that indicates the specific number of time-domain symbols in the control region. The PCFICH is mapped to the first time-domain symbol of the downlink subframe and to four Resource-Element Groups (REGs) in the frequency domain, distributed equally across the entire bandwidth. The specific location of each REG is related to the Physical Cell Identifier (PCI); different PCIs result in different REG locations. Terminal equipment determines the PHICH resource distribution by reading the Physical Broadcast Channel (PBCH).

[0114] In an LTE cell, all terminals search for the same PDCCH resource range of the DCI. The frequency domain resources of the control region are equal to the cell system bandwidth by default, and the time domain resources are fixed to the first 1 to 3 / 2 to 4 OFDM symbols of the downlink subframe, which are dynamically indicated by the PCFICH.

[0115] The size of the DCI field information in the PDCCH is only related to the DCI format and downlink bandwidth. The same DCI selects different aggregation levels according to channel quality. The aggregation level supports 1 to 8, representing the number of different Control Channel Elements (CCEs) occupied when the DCI is transmitted. The search space is divided into two main categories: UE-specific space and common space. The common space starts blind detection from CCE0, and the starting position of the UE-specific space is obtained through calculation.

[0116] In New Radio (NR), to improve link performance through beamforming of the PDCCH, optimize the PDCCH reference signal design, simplify base station scheduling, and save power consumption of the base station and terminals, NR uses UE-specific PDCCH resources. This concentrates the PDCCH monitoring range of a terminal from the system bandwidth to a single "control subband," namely the control resource set (CORESET).

[0117] To achieve low latency, NR introduces mini-slots and flexible channel structures. The LTE PDCCH, which can only be transmitted in the first few symbols of a subframe, cannot meet the requirements of Ultra-Reliable and Low-Latency Communications (URLLC) and Enhanced Mobile Broadband (eMBB) services. Furthermore, LTE terminals need to monitor the PDCCH in every downlink subframe, resulting in high terminal power consumption. Therefore, NR PDCCH requires a time-domain flexible PDCCH to match the flexibility of the data channel, thereby achieving on-demand transmission. This flexibility is ultimately reflected in the design of the PDCCH search space set.

[0118] NR carrier bandwidth can reach over 100MHz, and Time Division Multiplexing (TDM) alone cannot effectively multiplex PDCCH and PDSCH, resulting in a significant waste of frequency domain resources on both sides of the PDCCH. Therefore, 5G NR systems support Frequency-division multiplexing (FDM) for PDCCH and PDSCH. From a UE's perspective, its PDCCH is confined to the Control Subband, while it can simultaneously receive PDSCH outside the Control Subband. The base station's CORESET configuration implements this scheduling. Multiplexing between the PDCCH of other UEs and the PDSCH of the current UE is more complex, requiring information on PDCCH resources occupied by other UEs and further resolution through rate matching and other methods.

[0119] Currently, both LTE and NR use PDCCH to carry DCI (Data Channel Integration). However, PDCCH resources are limited, leading to significant congestion issues when facing frequent multi-user scheduling in the larger-scale access of 6G. Furthermore, UE blind detection has always been a major obstacle to UE energy efficiency. In NR, to support low-latency scheduling, DCI monitoring timing is configured more frequently, which is detrimental to terminal energy saving. Based on the fundamental design requirements of reducing UE blind detection and DCI congestion rate, a design for 6G is to use a data channel-borne DCI working mechanism, with semi-persistent scheduling (SPS) as the preferred method and dynamic scheduling of PDSCH as the next best option.

[0120] The advantages of this mechanism are as follows:

[0121] 1. The new DCI carried by PDSCH eliminates the need for blind testing by terminal devices, fundamentally reducing the number of blind tests required by the terminal.

[0122] 2. While maintaining the existing DCI in the network, it can also reduce the number of candidate positions of traditional DCI (legacy DC) carried in PDCCH, further reducing the number of blind detections in PDCCH.

[0123] 3. With the number of DCIs in the network remaining unchanged, the network side can reduce the configuration of legacy DCIs carried in the PDCCH, thereby reducing the blocking probability of legacy DCIs and helping to improve system throughput.

[0124] 4. Compared to the NR / LTE mechanism, it provides more flexible DCI transmission locations, which helps to enhance scheduling flexibility;

[0125] 5. Compared to PDCCH, PDSCH can be configured with more time and frequency resources, allowing for larger DCI payloads, which means that DCI can support more diverse functions.

[0126] The potential disadvantages of this mechanism are as follows:

[0127] 1. Affects PDSCH transmission.

[0128] 2. PDSCH has lower reliability requirements than PDCCH. After introducing this feature, reliability needs to be enhanced to ensure the transmission of DCI.

[0129] Regarding the first disadvantage, from the perspective of system throughput, it's necessary to consider the overall control / data resources and the specific network configuration. If the PDSCH itself is redundant and the DCI is insufficient, then the key factor affecting the overall system throughput is the number of DCIs, not the number of PDSCHs. Therefore, using PDSCHs to transmit DCIs is beneficial to the PDSCH transmission itself, and the impact on PDSCH transmission can only be considered from the perspective of a single PDSCH transmission. From a system perspective, in some scenarios, it can improve system throughput. Furthermore, compared to data information, control information occupies a very small percentage of the total PDSCH time-frequency resources, and its impact on PDSCH is limited. Additionally, this mechanism does not require PDSCHs to always carry DCIs; the network side can completely disable the function of carrying DCIs on PDSCHs when PDSCH resources are scarce.

[0130] Regarding the second disadvantage, the reliability requirements for PDSCH transmission are currently lower than those for PDCCH. However, PDSCH actually has multiple reliability / coverage enhancement schemes. Similarly, if PDSCH supports carrying DCI, conventional coverage enhancement approaches can be reused to mitigate this issue. Overall, PDSCH carrying DCI has significant technical advantages.

[0131] The terminal needs to decode the new DCI based on its modulation order, target / actual bit rate, spectral efficiency, etc. Therefore, how to determine the modulation order, target / actual bit rate, spectral efficiency, etc. of the new DCI is a problem that this solution needs to solve.

[0132] To address the aforementioned issues, this disclosure proposes a communication method that can indicate the modulation order, target / actual bit rate, spectral efficiency, etc. of the DCI to support terminal decoding of the new DCI. The specific details of this method are as follows.

[0133] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, which may include a terminal 101 and a network device 102. The method includes:

[0134] Step 2101: The network device sends the first information to the terminal.

[0135] In some embodiments, the terminal may receive first information from a network device, or determine the first information according to a predefined protocol. The terminal may determine decoding parameters for the first control information based on the first information, and then decode the first control information according to these decoding parameters. The first control information is carried through a data channel. Optionally, the first control information may be control information carried by a data channel, such as a new DCI (Digital Control Information), and the data channel may be, for example, a PDSCH (Programmable Spectrum Distributed Message Channel).

[0136] In some embodiments, the decoding parameters include at least one of the following: modulation order; code rate; spectral efficiency; and an index of the list of modulation and coding schemes (MCS).

[0137] In some embodiments, the data channel is one of the following: a data channel dynamically scheduled by second control information; a semi-statically configured data channel; or a semi-statically pre-configured and dynamically activated data channel. The second control information can be control information carried by a control channel, such as legacy DCI. The data channel dynamically scheduled by the second control information can be, for example, a PDSCH scheduled by legacy DCI. The semi-statically configured data channel can be, for example, an SPS configured by Radio Resource Control (RRC). The semi-statically pre-configured and dynamically activated data channel can be, for example, an SPS pre-configured by RRC and activated by legacy DCI.

[0138] In some embodiments, the first information includes at least one of the following: decoding parameters of the first control information carried by a data channel scheduled or activated by the second control information, wherein the second control information is carried by the control channel; a decoding parameter offset of the first control information carried by a data channel scheduled or activated by the second control information, wherein the decoding parameter offset is the offset between the decoding parameters of the first control information and the decoding parameters of the data channel carrying the first control information; decoding parameters of the first control information carried by the first data channel; a decoding parameter offset of the first control information carried by the first data channel; decoding parameters of the first control information carried by the second data channel; a decoding parameter offset of the first control information carried by the second data channel; a first set of decoding parameters of the first control information carried by a data channel configured by signaling sent by a network device, and a first decoding parameter indicated by the second control information sent by the network device, wherein the first decoding parameter is any one of the decoding parameters in the first set; a second set of decoding parameter offsets of the first control information carried by a data channel configured by signaling sent by a network device, and a first decoding parameter offset indicated by the second control information sent by the network device, wherein the first decoding parameter offset is any one of the decoding parameter offsets in the second set.

[0139] Step 2102: The terminal determines the decoding parameters of the first control information.

[0140] In some embodiments, the terminal may receive first information from a network device; determine decoding parameters for first control information based on the first information; or determine decoding parameters for first control information based on a predefined protocol, wherein the first control information is carried through a data channel.

[0141] In other words, the terminal can determine the decoding parameters of the first control information based on the first information or predefined by the protocol. Specifically, the terminal can determine the decoding parameters of the first control information in at least one of the following ways:

[0146] In other words, a decoding parameter indicator field, or indicator field, can be defined. This indicator field can be used to indicate the index value of the decoding parameter information table, and each index value can correspond to a decoding parameter. For example, a bit rate information indicator field can be defined to indicate the index value of the target bit rate information table, and each index value corresponds to a target bit rate value; or a modulation order information indicator field can be defined to indicate the index value of the modulation order information table, and each index value corresponds to a modulation order value; or a bit rate information indicator field and a spectral efficiency information indicator field can be defined to indicate the index value of the spectral efficiency information table, and each index value corresponds to a spectral efficiency value; or an MCS indicator field can be defined to indicate the index value of the MCS table, and each index value corresponds to a row of MCS information.

[0151] Method 2

[0152] In some embodiments, the first information may be the decoding parameter offset of the first control information carried by the data channel scheduled or activated by the second control information. The decoding parameter offset is the offset between the decoding parameters of the first control information and the decoding parameters of the data channel carrying the first control information.

[0199] In other words, the protocol can predefine the decoding parameter offset between the decoding parameters of the first control information and the decoding parameters of the data channel carrying the first control information. For example, the offset between the decoding parameters of the new DCI and the decoding parameters of the PDSCH / SPS carrying the new DCI can be predefine to be fixed at n. At this time, the decoding parameters of the first control information can be determined according to the decoding parameters of the data channel carrying the first control information and the offset value. The decoding parameters can be at least one of the following: modulation order; code rate; spectral efficiency.

[0200] Alternatively, the protocol may directly predefine the decoding parameters of the first control information. For example, the protocol may predefine the decoding parameters of the new DCI as n, where the decoding parameters may be at least one of the following: modulation order, code rate, and spectral efficiency.

In this case, the decoding parameters of the second control information can be determined and used as the decoding parameters of the first control information. The decoding parameters can be at least one of modulation order, code rate, and spectral efficiency.

[0204] In some embodiments, the terminal in methods 1 to 10 can determine the decoding parameters of the first control information based on the first information or protocol predefined. Optionally, the decoding parameters of the first control information can be indicated to the terminal by display indication, or the decoding parameters of the first control information can be indicated based on the existing MCS table.
