[0116] 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).

[0117] 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.

[0118] 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.

[0119] 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).

[0120] 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.

[0121] 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.

[0122] 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).

[0123] 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.

[0124] 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.

[0125] 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.

[0126] The advantages of this mechanism are as follows:

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 4. Compared to the NR / LTE mechanism, it provides more flexible DCI transmission locations, which helps to enhance scheduling flexibility;

[0131] 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.

[0132] The potential disadvantages of this mechanism are as follows:

[0133] 1. Affects PDSCH transmission.

[0134] 2. PDSCH has lower reliability requirements than PDCCH. After introducing this feature, reliability needs to be enhanced to ensure the transmission of DCI.

[0135] 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.

[0136] 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.

[0137] When the UE learns that a new-DCI exists on the received data channel, it will perform processes such as puncturing and rate matching on the data channel to extract the new-DCI it carries. If the corresponding information is not known, the UE can only blindly test each data channel to prevent missing the new-DCI, which would result in a large number of blind tests and high power consumption.

[0138] To address the aforementioned issues, this disclosure proposes a communication method. This method primarily discusses how to determine which PDSCH / SPS carries the new DCI. In other words, the terminal device needs to clearly identify which PDSCH / SPS carries the new DCI and which does not, so that the terminal can determine which data channels need to be processed. The specific content of this method is as follows.

[0139] 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.

[0218] Implicit determination methods include at least one of the following:

[0232] Optionally, the second control information can be a legacy DCI, and the first data channel can be an SPS. In other words, if the terminal fails to find the legacy DCI within a certain time, the UE assumes that the base station will send a new DCI in the SPS, meaning the UE needs to search for a new DCI in the SPS. When the terminal finds the legacy DCI, it does not need to retrieve the DCI in the SPS within that time range.

[0233] In some embodiments, the first data channel may optionally be configured to have all SPSs activated by default, or the first data channel may be configured to have SPSs enabled by the new DCI detection enable configuration.

[0234] Optionally, the time period or timer can be predefined by the protocol, or it can be configured by the network device using RRC signaling.

[0235] Method 15:

[0236] In some embodiments, determining whether a first data channel carries first control information based on a protocol predefined method includes: determining a third format based on a protocol predefined method; determining that the first data channel carries the first control information if control information with the third format is detected; or, determining that the first data channel carries the first control information within a time period or a timer's timing range if control information with the third format is detected.

[0237] In some embodiments, the first data channel may optionally be configured to have all SPSs activated by default, or the first data channel may be configured to have SPSs enabled by the new DCI detection enable configuration.

[0238] In other words, when the terminal retrieves control information of a certain format within the time period or timer's timing range, the UE assumes that the base station will send a new DCI in the SPS, meaning the UE searches for a new DCI in the SPS. Conversely, when the terminal does not retrieve control information of a certain format within the time period or timer's timing range, the base station defaults to not sending a new DCI in the SPS, and the terminal does not need to search for a new DCI in the SPS within the time period or timer's timing range.

[0239] Optionally, the time period or timer can be predefined by the protocol, or it can be configured by the network device using RRC signaling.

[0240] In some embodiments, methods 1 to 15 described above can determine whether the first data channel carries first control information through the indication of the first information or a predefined protocol. This allows the terminal to know in advance whether the first control information is carried on the first data channel, enabling the terminal to detect only the data channel carrying the first control information. This avoids the need for the terminal to detect each data channel when it is unclear whether the data channel carries control information. This reduces the number of detections by the terminal and lowers its power consumption.

[0254] In some embodiments, the network device may send first information to the terminal, but is not limited thereto; the network device may also send first information to other entities.

[0255] The following is an exemplary description of the above method.

[0256] The method illustrated in this disclosure relates to a configuration method for carrying control information, the full content of which is as follows.

[0257] Example 1

[0258] In a network, as shown in Figure 5, New-DCI is mapped onto a data channel. New-DCI is control information defined by a protocol and can be carried by the data channel. A data channel refers to a channel capable of carrying data information, including but not limited to at least one of the following: data channels dynamically scheduled through control information (e.g., PDSCH scheduled through legacy DCI), semi-statically configured data channels (e.g., SPS configured through RRC), and semi-statically pre-configured data channels that are dynamically activated (e.g., SPS pre-configured through RRC and activated by legacy DCI).

[0259] Based on the above, the explicit confirmation method for carrying new-DCI in the data channel includes at least one of the following:

[0260] Method 1:

[0261] The legacy DCI carried by the PDCCH contains a new-DCI bearer indication field, indicating whether the PDSCH scheduled by the legacy DCI carries the new DCI.

[0262] Furthermore, when the new-DCI bearer indication field indicates that the PDSCH scheduled by the legacy DCI carries the new-DCI, it means that: the PDSCH scheduled by the legacy DCI carries the new DCI; or, the PDSCH scheduled by the legacy DCI and the PDSCH scheduled by other subsequent legacy DCIs all carry the new DCI; or, the PDSCH scheduled by the legacy DCI and the PDSCH scheduled by other subsequent legacy DCIs, as well as other SPSs, all carry the new DCI.

[0263] Example 1: The new-DCI bearer indicator field contains one bit. When the bit is 0, it indicates that the PDSCH scheduled by the legacy DCI does not carry the new DCI; when the bit is 1, it indicates that the PDSCH scheduled by the legacy DCI carries the new DCI.

[0264] Example 2: The new-DCI bearer indicator field contains multiple bits. When the bit is 0, it indicates that the PDSCH scheduled by the legacy DCI does not carry a new DCI; when the bit is 1, it indicates that the PDSCH scheduled by the legacy DCI carries one new DCI; when the bit is 2, it indicates that the PDSCH scheduled by the legacy DCI carries two new DCIs.

[0265] Method 2:

[0266] The legacy DCI carried by the PDCCH contains a new-DCI bearer indication field, indicating whether the SPS activated by the legacy DCI carries the new DCI.

[0267] Furthermore, when the new-DCI bearer indication field indicates that the SPS activated by the legacy DCI carries the new DCI, it means that: the SPS activated by the legacy DCI carries the new DCI; or, the SPS activated by the legacy DCI and the PDSCHs of other subsequent legacy DCI scheduling all carry the new DCI; or, the SPS activated by the legacy DCI, the PDSCHs of other subsequent legacy DCI scheduling, and other SPSs all carry the new DCI.

[0268] Example 1: The new-DCI bearer indicator field contains one bit. When the bit is 0, it indicates that the SPS activated by the legacy DCI does not carry the new DCI; when the bit is 1, it indicates that the SPS activated by the legacy DCI carries the new DCI.

[0269] Example 2: The new-DCI bearer indicator field contains multiple bits. When the bit is 0, it indicates that the SPS activated by the legacy DCI does not carry a new DCI; when the bit is 1, it indicates that the first SPS activated by the legacy DCI carries a new DCI; when the bit is 2, it indicates that the first two SPS activated by the legacy DCI carry a new DCI.

[0270] Method 3:

[0271] The new-DCI bearer format indication parameter is configured by RRC. This parameter indicates the DCI format of the data channel scheduled to carry the new-DCI. When the new-DCI bearer format indication parameter determines the first format, the data channel scheduled with the first format carries the new-DCI.

[0272] Alternatively, the RRC can configure a new-DCI bearer indication parameter to indicate whether the SPS configured in the RRC signaling carries the new DCI.

[0273] Method 4:

[0274] The first DCI format is configured by RRC, and the new DCI is carried by the PDSCH scheduled by the first DCI format.

[0275] Method 5:

[0276] The second DCI format is configured by RRC, and the SPS activated by the second DCI format carries the new DCI.

[0277] Method 6:

[0278] A timer is configured by the RRC. Within the timer's time range, the data channel transmitted by the base station carries the new-DCI. Furthermore, the timer is triggered by the DCI or MAC CE.

[0279] Method 7:

[0280] A time window is configured by RRC. Within the time window, the data channel transmitted by the base station carries new-DCI. Furthermore, the time window is triggered by DCI or MAC CE.

[0281] Method 8:

[0282] The indication field indicates whether the data channel transmitted by the base station carries new-DCI. The indication field is carried by the first channel, which includes, but is not limited to, PDSCH, SPS, etc.

[0283] Example 2

[0284] In a network, New-DCI is mapped onto a data channel. New-DCI is control information defined by a protocol and can be carried by the data channel. A data channel refers to a channel capable of carrying data information, including but not limited to at least one of the following: a data channel dynamically scheduled through control information (e.g., a PDSCH scheduled through legacy DCI), a semi-statically configured data channel (e.g., an SPS configured through RRC), and a semi-statically pre-configured data channel that is dynamically activated (e.g., an SPS pre-configured through RRC and activated by legacy DCI).

[0285] Based on the above, the implicit acknowledgment methods for carrying new-DCI in the data channel include at least one of the following:

[0286] Method 1:

[0287] All PDSCHs scheduled using the special DCI format carry the new DCI, and the protocol predefines the special DCI format.

[0288] Method 2:

[0289] SPS activated with a special DCI format all carry a new DCI, and the protocol predefines the special DCI format.

[0290] Method 3:

[0291] The new DCI is carried by the PDSCH scheduled by the DCI scrambled by the special RNTI.

[0292] Method 4:

[0293] If the terminal device fails to find the legacy DCI within a certain period of time, the UE assumes that the base station will send a new DCI in the SPS, that is, the UE needs to search for a new DCI in the SPS.

[0294] Furthermore, once a legacy DCI is found, there is no need to search for DCIs in the SPS within the timer's time frame. The timer is scheduled according to the / RRC configuration. The SPS can be set to activate all SPSs by default, or the new DCI detection can be configured to enable the SPS.

[0295] Method 5:

[0296] When the terminal device retrieves a DCI of a certain format, the UE assumes that the base station will send a new DCI in the SPS. That is, the UE searches for a new DCI in the SPS. Furthermore, once a DCI of a different format is found, it is not necessary to search for DCI in the SPS within the timer's time range. The timer is scheduled according to the / RRC configuration. The SPS can be set to fully activated by default, or the new DCI detection is enabled by the configured SPS.

[0297] In summary, in the above embodiments of this solution, control information is carried by the data channel. The data channel can carry both data and control information, or it can carry only control information. This allows for explicit or implicit determination of whether the data channel carries control information, avoiding blind detection of all data channels by the terminal and reducing terminal power consumption.
