[0187] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0188] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0189] In some embodiments, the core network device may be a single device comprising one or more network elements, or multiple devices or a group of devices, each comprising all or part of one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0190] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0191] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0192] 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 deterministic 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).

[0193] Optionally, both LTE and New Radio (NR) use the physical downlink control channel (PDCCH) to carry DCI. However, PDCCH resources are limited, and they will cause significant congestion when facing frequent multi-user scheduling in the larger-scale access of 6G. Furthermore, blind detection of terminals has always been a major issue restricting terminal energy efficiency. In NR, to support low-latency scheduling, DCI monitoring timing is configured more frequently, which is detrimental to terminal energy efficiency. Therefore, based on the fundamental design requirements of reducing terminal blind detection and lowering DCI congestion rate, one design for 6G is a data channel-based DCI carrying mechanism. The data channel can include at least one of the following: a semi-persistent scheduling (SPS) channel, or a dynamically scheduled physical downlink shared channel (PDSCH). Optionally, the advantages of the data channel-based DCI carrying mechanism are as follows:

[0194] 1. DCI carried by PDSCH does not require blind testing by terminal equipment, fundamentally reducing the number of blind tests required by the terminal.

[0195] 2. While maintaining the existing DCI in the network, it can also reduce the number of candidate positions of DCI carried in PDCCH, further reducing the number of blind detections of PDCCH.

[0196] 3. With the number of DCIs in the network remaining unchanged, the network side can reduce the number of DCIs carried in the PDCCH, thereby reducing the probability of DCI blocking and helping to improve system throughput.

[0197] 4. Compared to the NR / LTE mechanism, it provides more flexible DCI transmission locations, which helps to enhance scheduling flexibility;

[0198] 5. Compared to PDCCH, PDSCH can be configured with more time and frequency resources, allowing for a larger DCI payload, which means that DCI can support a wider variety of functions.

[0199] However, how to determine the transmission resource allocation of DCI in the data channel is currently unclear.

[0291] For example, suppose the RRC signaling configuration frequency domain mapping type includes continuous mapping, non-continuous uniform and discrete mapping, and the second DCI signaling indication field contains 2 bits to indicate the index of the frequency domain mapping type, where 00 represents continuous mapping, 01 represents discrete mapping, 10 represents non-continuous uniform mapping, and 11 is empty.

[0292] For example, suppose the RRC signaling configuration frequency domain mapping pattern includes frequency domain mapping pattern1, frequency domain mapping pattern2 and frequency domain mapping pattern3. The second DCI signaling indication field contains 2 bits to indicate the index of the frequency domain mapping pattern, where 00 represents frequency domain mapping pattern1, 01 represents frequency domain mapping pattern2, 10 represents frequency domain mapping pattern3, and 11 is empty.

[0293] For example, suppose the RRC signaling configuration of the second reference position includes frequency domain mapping offset reference point 1, frequency domain mapping offset reference point 2 and frequency domain mapping offset reference point 3. The second DCI signaling indication field contains 2 bits to indicate the index of the second reference position, where 00 represents frequency domain mapping offset reference point 1, 01 represents frequency domain mapping offset reference point 2, 10 represents frequency domain mapping offset reference point 3, and 11 is empty.

[0294] Method 1-5b: The frequency domain resources of the first DCI are indicated by the second semi-static signaling and the second MAC CE signaling.

[0295] Optionally, the second semi-static signaling is used to indicate at least one alternative frequency domain resource of the first DCI, and the second MAC CE signaling is used to indicate the alternative frequency domain resource as the frequency domain resource of the first DCI.

[0296] For example, assuming the RRC signaling configuration frequency domain mapping type includes continuous mapping, non-continuous uniform and discrete mapping, the second MAC CE signaling indication field contains 2 bits to indicate the index of the frequency domain mapping type, where 00 represents continuous mapping, 01 represents discrete mapping, 10 represents non-continuous uniform mapping, and 11 is empty.

[0297] For example, suppose the RRC signaling configuration frequency domain mapping pattern includes frequency domain mapping pattern1, frequency domain mapping pattern2 and frequency domain mapping pattern3. The second MAC CE signaling indication field contains 2 bits to indicate the index of the frequency domain mapping pattern, where 00 represents frequency domain mapping pattern1, 01 represents frequency domain mapping pattern2, 10 represents frequency domain mapping pattern3, and 11 is empty.

[0298] For example, suppose the RRC signaling configuration of the second reference position includes frequency domain mapping offset reference point 1, frequency domain mapping offset reference point 2 and frequency domain mapping offset reference point 3. The second MAC CE signaling indication field contains 2 bits to indicate the index of the second reference position, where 00 represents frequency domain mapping offset reference point 1, 01 represents frequency domain mapping offset reference point 2, 10 represents frequency domain mapping offset reference point 3, and 11 is empty.

[0299] Optionally, the airspace resources of the first DCI may include at least one of the following:

[0300] The physical antenna port of the first DCI;

[0301] The logical antenna port of the first DCI;

[0302] The DMRS mapping type of the first DCI;

[0303] The first DCI's transmission reception point (TRP) identity (ID);

[0304] First DCI Spatial Resource Group ID.

[0305] Optionally, in some embodiments, the method for determining the airspace resources of the first DCI may include at least one of the following:

[0306] Method 1-1c: The airspace resources of the first DCI are agreed upon by the protocol.

[0307] Method 1-2c: The airspace resources of the first DCI are indicated by the first signaling.

[0308] Method 1-3c: The airspace resources of the first DCI are agreed upon by the protocol and indicated by the first signaling.

[0309] Method 1-4c: The airspace resources of the first DCI are indicated by the second semi-static signaling and the second dynamic signaling.

[0310] Method 1-5c: The airspace resources of the first DCI are indicated by the second semi-static signaling and the second MAC CE signaling.

[0311] For detailed information on methods 1-1c to 1-5c, please refer to the descriptions of methods 1-1a to 1-5a and methods 1-1b to 1-5b above.

[0312] Optionally, in some embodiments, the network device may use any of the above methods to determine the transmission resources of the first DCI. For example, the network device may use method 1-1a to determine the time domain resources of the first DCI, method 1-1b to determine the frequency domain resources of the first DCI, and method 1-1c to determine the spatial domain resources of the first DCI. Alternatively, the network device may use method 1-2a to determine the time domain resources of the first DCI, method 1-2b to determine the frequency domain resources of the first DCI, and method 1-2c to determine the spatial domain resources of the first DCI.

[0313] Optionally, in some embodiments, the protocol and / or the network device can directly determine which of the above methods to use to determine the transmission resources of the first DCI. For example, the protocol and / or the network device can determine whether to use method 1-1a to determine the time domain resources of the first DCI, method 1-1b to determine the frequency domain resources of the first DCI, or method 1-1c to determine the spatial domain resources of the first DCI. Alternatively, in other embodiments, the protocol can define multiple alternative methods, and the network device can select one of these alternative methods to determine the transmission resources of the first DCI. For example, the alternative methods agreed upon in the protocol may include: a first alternative method: determining the time-domain resources of the first DCI using method 1-1a, determining the frequency-domain resources of the first DCI using method 1-1b, and determining the spatial-domain resources of the first DCI using method 1-1c; and a second alternative method: determining the time-domain resources of the first DCI using method 1-2a, determining the frequency-domain resources of the first DCI using method 1-2b, and determining the spatial-domain resources of the first DCI using method 1-2c. The network device may select the second alternative method to determine the transmission resources of the first DCI and indicate the second alternative method to the terminal. Alternatively, in some embodiments, the network device may first configure multiple alternative methods, and then select one of the multiple alternative methods to determine the transmission resources of the first DCI and indicate that method to the terminal. For example, the alternative methods configured by the network device may include the first and second alternative methods described above. The network device may select the second alternative method to determine the transmission resources of the first DCI and indicate the second alternative method to the terminal.

[0314] From the above, it can be seen that the first DCI can occupy continuous transmission resources in the data channel. That is, the first DCI centrally occupies local resources in the data channel, so the resources not occupied by the first DCI can be centrally occupied by the data information in the data channel. This allows the data information to be centrally mapped, ensuring the transmission performance of the data information and reducing the impact of the first DCI on the transmission of the data information. Alternatively, the first DCI can occupy discrete or non-continuous transmission resources in the data channel. That is, the first DCI can be distributed and mapped in the data channel, which helps the first DCI avoid other signals in the data channel, prevents resource collisions between the first DCI and other signals, avoids interference from other signals, and ensures the transmission performance of the first DCI.

[0315] Step 2102: The network device indicates the transmission resources of the first DCI to the terminal.

[0316] Optionally, the network device may indicate the transmission resources of the first DCI to the terminal via semi-static signaling and / or dynamic signaling.

[0317] Step 2103: The terminal determines the transmission resources of the first DCI.

[0318] For a detailed description of the transmission resources of the first DCI, please refer to step 2101 above.

[0319] Optionally, the terminal may determine the transmission resources of the first DCI based on the protocol agreement, or the terminal may determine the transmission resources of the first DCI based on the network device configuration.

[0320] Optionally, in some embodiments, the specific content of the transmission resources of the first DCI can be directly agreed upon by the protocol and / or configured by the network device. For example, the time domain mapping type, time domain mapping pattern, and first reference position of the first DCI can be directly agreed upon by the protocol.

[0321] In other embodiments, the method for determining the transmission resources of the first DCI can be directly agreed upon by the protocol and / or configured by the network device. For example, in some embodiments, the transmission resources of the first DCI can be determined directly by the protocol and / or configured by the network device using methods 1-1a, 1-1b, and 1-1c described above. Alternatively, in other embodiments, multiple alternative methods can be agreed upon by the protocol, and the network device can select one of these alternative methods to determine the transmission resources of the first DCI and instruct it to the terminal. For example, the alternative methods agreed upon by the protocol may include: a first alternative method: using methods 1-1a, 1-1b, and 1-1c described above to determine the transmission resources of the first DCI; and a second alternative method: using methods 1-2a, 1-2b, and 1-2c described above to determine the transmission resources of the first DCI. The network device can select the second alternative method to determine the transmission resources of the first DCI and instruct the terminal on the second alternative method. Alternatively, in some embodiments, the network device may first configure multiple alternative methods, and then select one of these alternative methods to determine the transmission resources of the first DCI and indicate the method to the terminal. For example, the alternative methods configured by the network device may include the first alternative method and the second alternative method described above. The network device may select the second alternative method to determine the transmission resources of the first DCI and indicate the second alternative method to the terminal.

[0322] Optionally, in some embodiments, the terminal can also determine the transmission resources of the first DCI through blind detection. For example, in some embodiments, the network device can configure multiple locations for the terminal, and the terminal can attempt to detect at these multiple locations to determine whether the first DCI is included at these multiple locations. If the first DCI is detected, the transmission resources of the first DCI can be determined, such as the time domain resources and frequency domain resources of the first DCI.

[0323] Step 2104: The terminal and network equipment transmit the first DCI in the data channel based on the transmission resources of the first DCI.

[0324] Optionally, the network device can transmit the first DCI in the data channel based on the transmission resources of the first DCI, and the terminal can receive the first DCI in the data channel based on the transmission resources of the first DCI.

[0325] In summary, in the above embodiments, the first device determines the transmission resources of the first DCI carried in the data channel, so as to determine the transmission position of the first DCI in the data channel based on the transmission resources. Thus, the first device can send or receive the first DCI in the data channel based on the transmission position, ensuring that the first DCI can be carried and transmitted by the data channel, thereby achieving low-latency scheduling of DCI and reducing the DCI blocking rate, which is beneficial for terminal energy saving.

[0326] The determination method involved in the embodiments of this disclosure may include at least one of steps 2101 to 2104. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, step 2103 may be implemented as an independent embodiment, and step 2101+S2102 may be implemented as an independent embodiment, but is not limited thereto.

[0327] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0402] Optional embodiments

[0403] In a network, New-DCI is mapped onto a data channel. The new-DCI is control information defined by a protocol and can be carried by the data channel. The 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 via control information (e.g., a PDSCH scheduled via legacy DCI), a semi-statically configured data channel (e.g., an SPS configured via RRC), and a semi-statically pre-configured data channel dynamically activated (e.g., an SPS pre-configured via RRC and activated by legacy DCI).

[0404] The protocol predefines support for one or more new-DCI mapping resources. The configuration of the new-DCI mapping resource includes at least one of the following: time-domain mapping type, time-domain mapping pattern, and time-domain mapping offset reference point.

[0405] The time-domain mapping type indicates whether the new-DCI mapping resource is continuous in the time domain, and includes at least one of the types: continuous, discontinuous uniform, and discrete. Continuous means that the new-DCI mapping resource is a continuous mapping resource in the time domain, which can refer to physical continuity or logical continuity. Discontinuous uniform means that the new-DCI mapping resource is a discontinuous mapping resource in the time domain, but the resource distribution in each time domain is uniform; this can refer to physical discontinuity or logical discontinuity. Discrete means that the new-DCI mapping resource is a discontinuous mapping resource in the time domain, but the resource distribution in each time domain can be non-uniform; this can refer to physical discontinuity or logical discontinuity.

[0406] The time-domain mapping pattern is used to indicate the distribution of the new-DCI mapping resource in the time domain, including the location of the specific time-domain resources occupied by the new-DCI in the data channel and the number of time-domain resource units occupied. The protocol predefines at least one time-domain pattern.

The protocol predefines at least one reference point, including at least one of the following: the first symbol of the time slot, the first symbol of the data channel, the first symbol of the reference channel of the data channel, the last symbol of the time slot, the last symbol of the data channel, the last symbol of the reference channel of the data channel, and all symbols of the reference channel of the data channel.
