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.

[0186] 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 of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0187] 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).

[0188] 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.

[0189] 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 to each other or may be connected in any way. The connection may be direct or indirect, wired or wireless.

[0190] 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).

[0191] 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:

[0192] 1. DCI carried by PDSCH does not require blind testing by terminal equipment, fundamentally reducing the number of blind tests required by the terminal.

[0193] 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.

[0194] 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.

[0195] 4. Compared to the NR / LTE mechanism, it provides more flexible DCI transmission locations, which helps to enhance scheduling flexibility;

[0196] 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.

[0197] However, how to determine the frequency domain resource allocation of DCI in the data channel is currently unclear.

[0198] Figure 2A is an interactive schematic diagram illustrating a determination method according to an embodiment of the present disclosure. As shown in Figure 2A, this embodiment of the disclosure relates to a determination method for a communication system 100; the method includes:

In some embodiments, the relevant information of the first DCI can be directly agreed upon by a protocol, or the relevant information of the first DCI can be configured by signaling, for example, by at least one of RRC signaling, MAC CE signaling, and the second DCI; or, at least one alternative relevant information can be agreed upon by a protocol first, and then the network device can activate the alternative relevant information as the relevant information of the first DCI through signaling; or, the network device can first semi-statically configure at least one alternative relevant information, and then dynamically activate the alternative relevant information as the relevant information of the first DCI.

[0206] Optionally, in some embodiments, the network device may determine the frequency domain configuration of the first DCI based on a protocol agreement, while in other embodiments, the network device may determine the frequency domain configuration of the first DCI autonomously.

[0207] Optionally, in some embodiments, the first DCI may occupy continuous frequency domain resources in the data channel (or: the first DCI is continuously mapped in the frequency domain of the data channel), while in other embodiments, the first DCI may occupy non-continuous (or discrete) frequency domain resources in the data channel (or: the first DCI is discretely or non-continuously mapped in the frequency domain of the data channel).

[0208] Optionally, the aforementioned "continuous frequency domain resources" can refer to physically continuous frequency domain resources or logically continuous frequency domain resources. Optionally, "physically continuous frequency domain resources" can be understood, for example, as frequency domain resources with continuous frequency domain positions; "logically continuous frequency domain resources" can be understood, for example, as frequency domain resources with continuous frequency domain unit numbers, such as multiple resource blocks (RBs) with consecutive numbers; in some embodiments, when frequency domain resources are logically continuous, they may or may not be physically continuous.

[0209] Optionally, in some embodiments, the frequency domain configuration of the first DCI may include at least one of the following: the frequency domain offset value of the first DCI, the bandwidth resources occupied by the first DCI (or the frequency domain resources mapped by the first DCI, the frequency domain bandwidth mapped by the first DCI, etc.), and whether the first DCI hops frequencies in the frequency domain.

[0210] Optionally, the frequency domain offset value of the first DCI described above can be used to indicate: the frequency domain position (such as the start frequency domain position or the end frequency domain position) of the first DCI offset by frequency domain units relative to the first reference position; for example, the frequency domain offset value of the first DCI can be N frequency domain units, then the start frequency domain position or the end frequency domain position of the first DCI can be: the position after the first reference position has been offset by N frequency domain units.

[0211] Optionally, in some embodiments, the first reference position described above may include at least one of the following:

[0223] Optionally, in some embodiments, the "position of the first RB or the first RE of the reference signal in the data channel where the first DCI is located" may refer to the position of the first RB or the first RE of any reference signal in the data channel where the first DCI is located. For example, it may refer to the position of the first RB or the first RE of the first reference signal in the data channel where the first DCI is located, or it may refer to the position of the first RB or the first RE of the last reference signal in the data channel where the first DCI is located. Optionally, in other embodiments, the "position of the first RB or the first RE of the reference signal in the data channel where the first DCI is located" may also refer to the position of the first RB or the first RE of all reference signals in the data channel where the first DCI is located.

[0224] Optionally, the reference signal in the data channel where the first DCI is located may include at least one of the following: Synchronization Signal Block (SSB), Positioning Reference Signal (PRS), Low Power Synchronization Signals (LPSS), Tracking Reference Signal (TRS), Channel State Information Reference Signal (CSI-RS), and Demodulation Reference Signal (DMRS).

[0225] Optionally, in some embodiments, the frequency domain unit may be predefined by the protocol, and the frequency domain unit may include at least one of the following: RE, RB, Resource element group (REG), and Resource block group (RBG).

[0226] Optionally, in some embodiments, the method for determining the "frequency domain offset value of the first DCI" described above may include at least one of the following:

[0227] Method 1-1a: The frequency domain offset value of the first DCI is agreed upon by the protocol.

[0228] Method 1-2a: The frequency domain offset value of the first DCI is indicated by the first semi-static signaling.

[0229] Method 1-3a: The frequency domain offset value of the first DCI is indicated by the first dynamic signaling.

[0230] Method 1-4a: The frequency domain offset value of the first DCI is indicated by the first MAC CE signaling.

[0231] Method 1-5a: The frequency domain offset value of the first DCI is agreed upon by the protocol and indicated by the second semi-static signaling.

[0232] Optionally, at least one alternative frequency domain offset value for the first DCI can be agreed upon by the protocol, and the alternative frequency domain offset value can be indicated as the frequency domain offset value of the first DCI by the second semi-static signaling. For example, the range of values ​​for the frequency domain offset value of the first DCI can be agreed upon by the protocol, and then the specific value of the frequency domain offset value of the first DCI can be indicated by the second semi-static signaling.

[0233] Method 1-6a: The frequency domain offset value of the first DCI is indicated by the third semi-static signaling and the second dynamic signaling.

[0234] Optionally, the third semi-static signaling can be used to indicate at least one alternative frequency domain offset value of the first DCI, and the second dynamic signaling can be used to indicate the alternative frequency domain offset value as the frequency domain offset value of the first DCI. For example, the third semi-static signaling can be used to indicate the range of values ​​for the frequency domain offset value of the first DCI, and the second dynamic signaling can indicate the specific value of the frequency domain offset value of the first DCI.

[0235] Method 1-7a: The frequency domain offset value of the first DCI is indicated by the third semi-static signaling and the second MAC CE signaling.

[0236] Optionally, the third semi-static signaling can be used to indicate at least one alternative frequency domain offset value of the first DCI, and the second MAC CE signaling can be used to indicate the alternative frequency domain offset value as the frequency domain offset value of the first DCI. For example, the third semi-static signaling can be used to indicate the range of values ​​for the frequency domain offset value of the first DCI, and the second MAC CE signaling can indicate the specific value of the frequency domain offset value of the first DCI.

[0237] Optionally, the aforementioned semi-static signaling (i.e., the first semi-static signaling, the second semi-static signaling, and the third semi-static signaling) may include, for example, RRC signaling. Optionally, the aforementioned dynamic signaling (i.e., the first dynamic signaling and the second dynamic signaling) may include, for example, the second DCI and / or MAC CE signaling.

[0238] Optionally, the aforementioned "bandwidth resources occupied by the first DCI" can be agreed upon by a protocol and / or configured by the network device. When the bandwidth resources occupied by the first DCI are configured by the network device, in some embodiments, the network device can semi-statically configure the bandwidth resources occupied by the first DCI; in other embodiments, the network device can dynamically indicate the bandwidth resources occupied by the first DCI.

[0239] Optionally, in some embodiments, the method for determining "bandwidth resources occupied by the first DCI" may include at least one of the following:

[0240] Method 1-1b: The bandwidth resources occupied by the first DCI are the same as the bandwidth resources of the data channel where the first DCI is located.

[0241] For example, assuming the data channel where the first DCI is located is PDSCH and its bandwidth is 60 RBs, then the bandwidth resources occupied by the first DCI can be 60 RBs.

[0242] Method 1-2b: The bandwidth resources occupied by the first DCI do not exceed the bandwidth resources of the data channel where the first DCI is located.

[0243] Optionally, the first DCI can occupy as much bandwidth resource as possible. In some embodiments, the bandwidth resource occupied by the first DCI can be determined according to the frequency domain resource mapping granularity of the data channel where the first DCI is located. This "frequency domain resource mapping granularity of the data channel where the first DCI is located" can be understood, for example, as the frequency domain length occupied by one frequency domain segment of the data channel where the first DCI is located. For example, assuming the data channel where the first DCI is located is PDSCH with a bandwidth of 62 RBs, and the frequency domain resource mapping granularity of the data channel where the first DCI is located is 6 RBs, then it can be determined that the first DCI occupies 10 frequency domain resource mapping granularities, that is, the bandwidth resource occupied by the first DCI is 60 RBs.

[0244] Method 1-3b: The bandwidth resources occupied by the first DCI are a subset of the bandwidth resources of the data channel where the first DCI is located.

[0245] Optionally, a first offset value may be spaced between the starting position of the bandwidth resources occupied by the first DCI and the starting position of the bandwidth resources of the data channel where the first DCI is located, and / or a second offset value may be spaced between the ending position of the bandwidth resources occupied by the first DCI and the ending position of the bandwidth resources of the data channel where the first DCI is located. The first and second offset values ​​may be agreed upon by a protocol and / or configured by the network device.

[0246] Optionally, the above-mentioned "the starting position of the bandwidth resources occupied by the first DCI and the starting position of the bandwidth resources of the data channel where the first DCI is located are separated by a first offset value" can be understood as follows: the bandwidth resources occupied by the first DCI are all the bandwidth resources after the starting bandwidth resources of the data channel where the first DCI is located are offset by the first offset value.

[0247] For example, in some embodiments, assuming the first offset is 2RB and the data channel where the first DCI is located is PDSCH with a bandwidth of 62RB, the bandwidth resource occupied by the first DCI can be: the total bandwidth resource after the initial bandwidth resource of the data channel where the first DCI is located is offset by 2RB, so the bandwidth resource occupied by the first DCI is 60RB.

[0248] Method 1-4b: The bandwidth resources occupied by the first DCI are one-Nth of the bandwidth resources of the data channel where the first DCI is located, where N is a positive integer.

[0249] Optionally, N can be agreed upon by a protocol and / or configured by the network device; for example, N can be configured by RRC signaling.

[0250] For example, assuming the data channel where the first DCI is located is PDSCH with a bandwidth of 48 RBs and N is 2, the bandwidth resources occupied by the first DCI can be the upper half or the lower half of the bandwidth resources of the data channel where the first DCI is located. In this case, the bandwidth resources occupied by the first DCI are 24 RBs.

[0251] Method 1-5b: The bandwidth resources occupied by the first DCI are at least one of the M bandwidth resources. The M bandwidth resources are: the bandwidth resources obtained after the bandwidth resources of the data channel where the first DCI is located are divided into M parts, where M is a positive integer.

[0252] Optionally, M can be defined by a protocol and / or configured by the network device.

[0253] In some embodiments, the network device can configure the bandwidth resources occupied by the first DCI to be at least one of the M bandwidth resources via a fifth signaling. This fifth signaling may include at least one of RRC signaling, the second DCI, and MAC CE signaling.

[0254] Optionally, in some embodiments, the fifth signaling may include a bitmap, where bits in the bitmap may correspond to bandwidth resources in M ​​bandwidth resources. The bit value carried by the bit may be used to indicate whether the bandwidth resource corresponding to the bit is occupied by the first DCI. For example, when the bit carried by the bit is a first value (e.g., 1), it indicates that the bandwidth resource corresponding to the bit is occupied by the first DCI; when the bit carried by the bit is a second value (e.g., 0), it indicates that the bandwidth resource corresponding to the bit is not occupied by the first DCI.

[0255] For example, assuming the data channel where the first DCI resides is PDSCH with a bandwidth of 48 RBs, these 48 RBs are divided into 4 parts. The bitmap of the fifth signaling includes 4 bits, where the first bit of the bitmap corresponds to the first part of the bandwidth resource of the data channel where the first DCI resides, the second bit of the bitmap corresponds to the second part of the bandwidth resource of the data channel where the first DCI resides, and so on. Therefore, when the fifth signaling carries 0110, it can indicate that the bandwidth resource occupied by the first DCI includes the second and third parts of the bandwidth resource of the data channel where the first DCI resides. In this case, the bandwidth resource occupied by the first DCI can be 24 RBs.

[0256] Optionally, in some embodiments, the fifth signaling may not include a bitmap, but directly configures the bandwidth resources occupied by the first DCI to be at least one of the M bandwidth resources. For example, the fifth signaling may directly configure the bandwidth resources occupied by the first DCI to include the second and third bandwidth resources of the data channel where the first DCI is located.

[0257] Optionally, in some embodiments, the aforementioned "whether the first DCI hops frequencies in the frequency domain" can be indicated by a first signaling; optionally, the first signaling may include at least one of RRC signaling, a second DCI, and MAC CE signaling. The first signaling may use at least one of the following methods to indicate whether the first DCI hops frequencies in the frequency domain:

[0258] Method 1-1c: When the first signaling bears a first value (e.g., 1), it indicates that the first DCI will hop frequency; when the first signaling bears a second value (e.g., 0), it indicates that the first DCI will not hop frequency.

[0259] Method 1-2c: The first signaling is used to carry a bit map. The bits of the bit map correspond to time domain symbols. The value carried by the bit is used to indicate whether the first DCI hops frequency on the time domain symbol corresponding to the bit.

[0260] For example, the bitmap carried by the first signaling may include three bits, which correspond sequentially to the first time-domain symbol, the second time-domain symbol, and the third time-domain symbol of the first DCI. When a bit carries a first value (e.g., 1), it indicates that the first DCI will hop frequency on the time-domain symbol corresponding to that bit. When a bit carries a second value (e.g., 0), it indicates that the first DCI will not hop frequency on the time-domain symbol corresponding to that bit. If the first signaling carries a bitmap of 011, it means that the first DCI will not hop frequency on the first time-domain symbol, but will hop frequency on the second and third time-domain symbols.

[0261] Method 1-3c: The first signaling includes a first indication field. When the first indication field carries different values, the first signaling indicates whether the first DCI hops frequency on different time domain symbols.

[0262] For example, when the first indicator field carries the third value (such as 1), it indicates that the first DCI does not hop frequencies; when the first indicator field carries the fourth value (such as 2), it indicates that the first DCI does not hop frequencies on the first time domain symbol and hops frequencies on the second time domain symbol; when the first indicator field carries the fifth value (such as 3), it indicates that the first DCI does not hop frequencies on the first time domain symbol, hops frequencies on the second time domain symbol, hops frequencies on the third time domain symbol, and so on.

[0263] Optionally, in some embodiments, the network device may use any of the above methods to determine the frequency domain configuration of the first DCI. For example, the network device may use method 1-1a to determine the frequency domain offset value of the first DCI, method 1-1b to determine the bandwidth resources occupied by the first DCI, and method 1-1c to determine whether the first DCI is frequency hopping in the frequency domain. Alternatively, the network device may use method 1-2a to determine the frequency domain offset value of the first DCI, method 1-2b to determine the bandwidth resources occupied by the first DCI, and method 1-2c to determine whether the first DCI is frequency hopping in the frequency domain.

[0264] Optionally, in some embodiments, the protocol can directly specify which of the above methods to use to determine the frequency domain configuration of the first DCI. The network device can directly determine the frequency domain configuration of the first DCI based on the method agreed upon in the protocol. For example, the protocol may agree to use method 1-1a to determine the frequency domain offset value of the first DCI, method 1-1b to determine the bandwidth resources occupied by the first DCI, and method 1-1c to determine whether the first DCI hops frequencies in the frequency domain. Alternatively, in other embodiments, the protocol may agree upon multiple alternative methods, and the network device may select one of these alternative methods to determine the frequency domain configuration of the first DCI. For example, the alternative methods agreed upon in the protocol may include: a first alternative method: using method 1-1a to determine the frequency domain offset value of the first DCI, using method 1-1b to determine the bandwidth resources occupied by the first DCI, and using method 1-1c to determine whether the first DCI performs frequency hopping in the frequency domain; a second alternative method: using method 1-2a to determine the frequency domain offset value of the first DCI, using method 1-2b to determine the bandwidth resources occupied by the first DCI, and using method 1-2c to determine whether the first DCI performs frequency hopping in the frequency domain. Furthermore, the network device may select the second alternative method to determine the frequency domain configuration 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 the network device may select one of the multiple alternative methods to determine the frequency domain configuration 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. Furthermore, the network device may select the second alternative method to determine the frequency domain configuration of the first DCI and indicate the second alternative method to the terminal.

[0265] For example, Figure 2B is a schematic diagram of the frequency domain resources occupied by the first DCI according to an embodiment of the present disclosure. As shown in Figure 2B, the length of the time slot is 14 time domain symbols, the data channel carrying the first DCI is PDSCH, the PDSCH is scheduled by the second DCI, the PDSCH occupies time domain symbols #2 to #11, and occupies 7 REs in the frequency domain. The RRC signaling configuration uses the above-described method 1-2a to determine the frequency domain offset value of the first DCI, and uses the above-described method 1-3b to determine the bandwidth resources occupied by the first DCI. The first DCI does not hop frequencies. According to the RRC signaling configuration, the frequency domain offset value of the first DCI is 2. Therefore, the first DCI is mapped in the frequency domain starting from the 3rd RE of the PDSCH and continuously mapped to the entire PDSCH bandwidth.

[0266] For example, Figure 2C is a schematic diagram of the frequency domain resources occupied by the first DCI according to an embodiment of the present disclosure. As shown in Figure 2C, the length of the time slot is 14 time domain symbols, the data channel carrying the first DCI is PDSCH, PDSCH is scheduled by the second DCI, PDSCH occupies time domain symbols #2 to #11, and occupies 7 REs in the frequency domain. The RRC signaling configuration uses the above-described method 1-2a to determine the frequency domain offset value of the first DCI, and uses the above-described method 1-3b to determine the bandwidth resources occupied by the first DCI. The first DCI performs frequency hopping. According to the RRC signaling configuration, the frequency domain offset value of the first DCI is 2, the bandwidth resources occupied by the first DCI are 2, and the first DCI performs frequency hopping. Then, the first DCI starts mapping from the 3rd RE of PDSCH in the frequency domain, maps two REs consecutively, and frequency hopping is enabled.

[0267] Optionally, in some embodiments, the first DCI may occupy non-contiguous frequency domain resources. For example, the first DCI may occupy multiple frequency domain segments, where at least two adjacent frequency domain segments are not contiguous. In this case, the frequency domain configuration of the first DCI may include at least one of the following: the frequency domain offset value of the first DCI, the number of frequency domain segments occupied by the first DCI (or: the total number of frequency domain segments occupied by the first DCI), the duration of the frequency domain segments occupied by the first DCI (or: the granularity of the frequency domain segments occupied by the first DCI), the spacing between adjacent frequency domain segments occupied by the first DCI, and whether the first DCI performs frequency hopping in the frequency domain.

[0268] Optionally, in some embodiments, the aforementioned "discontinuous frequency domain resources" may include uniform discontinuous frequency domain resources or non-uniform discontinuous frequency domain resources. Optionally, "uniform discontinuous frequency domain resources" may refer to a first DCI occupying discontinuous frequency domain resources, but the resource distribution within each frequency domain unit is uniform. Optionally, the aforementioned "non-uniform discontinuous frequency domain resources" may refer to a first DCI occupying discontinuous frequency domain resources, but the resource distribution within each frequency domain unit may be non-uniform.

[0269] Optionally, the aforementioned "discontinuous frequency domain resources" can refer to frequency domain resources that are physically discontinuous or logically discontinuous. Optionally, "physically discontinuous frequency domain resources" can be understood, for example, as frequency domain resources whose frequency domain positions are discontinuous; "logically discontinuous frequency domain resources" can be understood, for example, as frequency domain resources whose frequency domain numbers are discontinuous, such as multiple REs with discontinuous numbers.

[0270] Optionally, for a detailed description of the "frequency domain offset value of the first DCI", please refer to methods 1-1a to 1-7a above.

[0271] Optionally, for a detailed explanation of whether the first DCI is frequency-hopping in the frequency domain, please refer to methods 1-1c to 1-3c above.

[0272] Optionally, the "number of frequency domain segments occupied by the first DCI" can be m, where m > 0 and m is an integer. The method for determining m can include at least one of the following:

[0273] Method 2-1a: As agreed upon in the agreement.

[0274] Method 2-2a: Configured by the second signaling.

[0275] Optionally, the second signaling may include at least one of RRC signaling, second DCI, and MAC CE signaling.

[0276] For example, if m=1, it means that the first DCI occupies one frequency domain segment in the frequency domain, that is, the first DCI is a continuous mapping in the frequency domain; if m=2, it means that the first DCI is two non-continuously mapped frequency domain segments in the frequency domain.

[0277] Optionally, the method for determining the "duration length of the frequency domain segment occupied by the first DCI" may include at least one of the following:

[0278] Method 2-1b: As agreed upon in the agreement.

[0279] Method 2-2b: Configured by third signaling.

[0280] Optionally, the third signaling may include at least one of RRC signaling, second DCI, and MAC CE signaling.

[0281] For example, if the duration of the frequency domain segment occupied by the first DCI is 6, it means that one frequency domain segment of the first DCI occupies 6 frequency domain units in the frequency domain.

[0282] Optionally, the method for determining the "spacing between adjacent frequency bands occupied by the first DCI" may include at least one of the following:

[0283] Method 2-1c: As agreed upon in the agreement.

[0284] Method 2-2c: Configured by the fourth signaling.

[0285] Optionally, the fourth signaling may include at least one of RRC signaling, second DCI, and MAC CE signaling.

[0286] For example, if the spacing between adjacent frequency domain segments occupied by the first DCI is 2, it means that the spacing between adjacent frequency domain segments of the first DCI in the frequency domain is 2 frequency domain units.

[0287] Optionally, in some embodiments, the "spacing between adjacent frequency domain segments occupied by the first DCI" can be determined by a first spacing pattern. This first spacing pattern can include at least one spacing value, where the spacing value is an integer greater than 0. Different spacing values ​​in the first spacing pattern are used to indicate the spacing between different adjacent frequency domain segments occupied by the first DCI. For example, the first spacing pattern can contain multiple integers greater than 0 {k1, k2, ..., km-1}, where k1 can be the spacing between the first and second frequency domain segments (e.g., time-domain spacing), k2 is the spacing between the second and third frequency domain segments (e.g., time-domain spacing), and so on.

[0288] Optionally, the first signaling, second signaling, third signaling, and fourth signaling may be the same or different.

[0289] Optionally, in some embodiments, the network device may use any of the above methods to determine the frequency domain configuration of the first DCI. For example, the network device may use method 1-1a to determine the frequency domain offset value of the first DCI, method 2-1a to determine the number of frequency domain segments occupied by the first DCI, method 2-1b to determine the duration of the frequency domain segments occupied by the first DCI, method 2-1c to determine the spacing between adjacent frequency domain segments occupied by the first DCI, and method 1-1c to determine whether the first DCI hops frequencies in the frequency domain. Alternatively, the network device may use method 1-2a to determine the frequency domain offset value of the first DCI, method 2-2a to determine the number of frequency domain segments occupied by the first DCI, method 2-2b to determine the duration of the frequency domain segments occupied by the first DCI, method 2-2c to determine the spacing between adjacent frequency domain segments occupied by the first DCI, and method 1-2c to determine whether the first DCI hops frequencies in the frequency domain.

[0290] Optionally, in some embodiments, the protocol can directly specify which of the above methods to use to determine the frequency domain configuration of the first DCI. The network device can directly determine the frequency domain configuration of the first DCI based on the method agreed upon in the protocol. For example, the protocol may agree to use method 1-1a to determine the frequency domain offset value of the first DCI, method 2-1a to determine the number of frequency domain segments occupied by the first DCI, method 2-1b to determine the duration of the frequency domain segments occupied by the first DCI, method 2-1c to determine the spacing between adjacent frequency domain segments occupied by the first DCI, and method 1-1c to determine whether the first DCI hops frequencies in the frequency domain. Alternatively, in other embodiments, the protocol may agree upon multiple alternative methods, and the network device may select one of these alternative methods to determine the frequency domain configuration of the first DCI. For example, the alternative methods agreed upon in the protocol may include: a first alternative method: using method 1-1a to determine the frequency domain offset value of the first DCI, using method 2-1a to determine the number of frequency domain segments occupied by the first DCI, using method 2-1b to determine the duration of the frequency domain segments occupied by the first DCI, using method 2-1c to determine the spacing between adjacent frequency domain segments occupied by the first DCI, and using method 1-1c to determine whether the first DCI performs frequency hopping in the frequency domain; a second alternative method: using method 1-2a to determine the frequency domain offset value of the first DCI, using method 2-2a to determine the number of frequency domain segments occupied by the first DCI, using method 2-2b to determine the duration of the frequency domain segments occupied by the first DCI, using method 2-2c to determine the spacing between adjacent frequency domain segments occupied by the first DCI, and using method 1-2c to determine whether the first DCI performs frequency hopping in the frequency domain. Furthermore, the network device may select the second alternative method to determine the frequency domain configuration 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 these alternative methods to determine the frequency domain configuration 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. Furthermore, the network device may select the second alternative method to determine the frequency domain configuration of the first DCI and indicate the second alternative method to the terminal.

[0291] For example, Figures 2D and 2E are schematic diagrams illustrating the frequency domain resources occupied by the first DCI according to an embodiment of this disclosure. As shown in Figure 2D, the length of the time slot is 14 time domain symbols, the data channel carrying the first DCI is PDSCH, PDSCH is scheduled by the second DCI, PDSCH occupies time domain symbols #2 to #11, and occupies 8 REs in the frequency domain. The RRC signaling configuration uses method 1-1a to determine the frequency domain offset value of the first DCI, method 2-1a to determine the number of frequency domain segments occupied by the first DCI, and method 2-1b to determine the frequency domain segments occupied by the first DCI. The duration length, the spacing between adjacent frequency domain segments occupied by the first DCI determined by method 2-1c above, and whether the first DCI hops frequencies in the frequency domain determined by method 1-1c above, wherein, according to the RRC signaling configuration, the frequency domain offset value of the first DCI is 1, the number of frequency domain segments occupied by the first DCI is 2, the duration length of the frequency domain segments occupied by the first DCI is 3, and the spacing between adjacent frequency domain segments occupied by the first DCI is 1, then the first DCI starts mapping from the second RE of PDSCH in the frequency domain and maps two frequency domain segments consecutively, with a duration length of 3RE and an interval of 1RE.

[0292] Optionally, the above methods can be combined with each other. For example, method 2-1a and method 2-1c can be combined. This disclosure does not specifically limit the specific combination method.

[0293] Therefore, in the above embodiments, the first DCI can occupy continuous frequency domain 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 non-contiguous frequency domain 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 the first DCI from colliding with other signals, avoids interference from other signals, and ensures the transmission performance of the first DCI.

[0294] Step 2102: The network device instructs the terminal on the frequency domain configuration of the first DCI.

[0295] Optionally, the network device may indicate the frequency domain configuration of the first DCI to the terminal via semi-static signaling and / or dynamic signaling.

[0296] Step 2103: The terminal determines the frequency domain configuration of the first DCI.

[0297] For a detailed description of the frequency domain configuration of the first DCI, please refer to step 2101 above.

[0298] Optionally, the terminal may determine the frequency domain configuration of the first DCI based on the protocol agreement, or the terminal may determine the frequency domain configuration of the first DCI based on the network device configuration.

[0299] Optionally, in some embodiments, the specific content of the frequency domain configuration of the first DCI can be directly agreed upon by the protocol and / or configured by the network device. For example, the protocol can directly agree that the first DCI starts mapping from the second RE of the PDSCH and maps two frequency domain segments consecutively, with a duration of 3 REs and an interval of 1 RE.

[0300] In other embodiments, the method for determining the frequency domain configuration 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 frequency domain configuration of the first DCI can be determined directly by the protocol and / or by the network device using the methods 1-1a, 2-1a, 2-1b, 2-1c, 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 frequency domain configuration 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 the methods 1-1a, 2-1a, 2-1b, 2-1c, and 1-1c described above to determine the frequency domain configuration of the first DCI; and a second alternative method: using the methods 1-2a, 2-2a, 2-2b, 2-2c, and 1-2c described above to determine the frequency domain configuration of the first DCI. Furthermore, the network device can select the second alternative method described above to determine the frequency domain configuration of the first DCI and indicate the second alternative method to the terminal. Alternatively, in some embodiments, the network device can first configure multiple alternative methods, and then the network device can select one of the multiple alternative methods to determine the frequency domain configuration 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, and the network device can select the second alternative method to determine the frequency domain configuration of the first DCI and indicate the second alternative method to the terminal.

[0301] Optionally, in some embodiments, the terminal can also determine the frequency domain configuration 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 frequency domain configuration of the first DCI can be determined. For example, the frequency domain offset value of the first DCI, the bandwidth resources occupied by the first DCI, and whether the first DCI is frequency hopping in the frequency domain can be determined.

[0302] Step 2104: The terminal and network device transmit the first DCI in the data channel based on the frequency domain configuration of the first DCI.

[0303] Optionally, the network device can transmit the first DCI in the data channel based on the frequency domain configuration of the first DCI, and the terminal can receive the first DCI in the data channel based on the frequency domain configuration of the first DCI.

[0304] In summary, in the above embodiments, the first device determines the frequency domain configuration of the first DCI carried in the data channel, so as to determine the frequency domain position of the first DCI in the data channel based on the frequency domain configuration. Thus, the first device can send or receive the first DCI in the data channel based on the frequency domain 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.

[0305] 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.

[0306] 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.

[0374] In some embodiments, the above methods may include the methods described in the embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0375] The determination method involved in the embodiments of this disclosure may include at least one of steps 4101 to 4103. For example, step 4101 may be implemented as a separate embodiment, and step 4102 may be implemented as a separate embodiment, but are not limited thereto.

[0376] 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.

[0377] The following is an exemplary description of the above method.

[0378] This disclosure mainly discusses the new control information (New-DCI) (i.e., the aforementioned first DCI), which is the control information carried by the data channel, the physical frequency domain resource location mapped in the data channel (e.g., PDSCH, SPS, etc.), and the corresponding frequency domain resource configuration, etc.

[0379] Optional embodiments

[0380] 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 (i.e., the aforementioned second 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). The data channel may carry both data and control information, or it may carry only control information.

[0381] The protocol predefines support for one or more new-DCI mapping resources, each containing frequency domain resource information. The new-DCI is mapped continuously in the frequency domain of the data channel, meaning it occupies contiguous frequency domain resources. Alternatively, the new-DCI is mapped discretely in the frequency domain of the data channel, meaning it occupies non-contiguous frequency domain resources. The relevant configuration parameters of the new-DCI mapping resource include at least one of frequency domain offset, bandwidth resources, and skipping.

[0382] Based on the above, the method for determining the first frequency domain offset of the new-DCI mapping resource includes at least one of the following:

[0383] Optional Example 1_1:

[0384] The protocol predefines a value for the first frequency domain offset, which is 'a' first frequency domain units. The first frequency domain unit is predefined by the protocol. For example, the first frequency domain unit is at least one of RE, RB, REG, and RBG.

[0385] Optional Example 1_2:

[0386] The semi-static signaling indicates the value of the first frequency domain offset, which is 'a' times the first frequency domain unit.

[0387] Optional Example 1_3:

[0388] The dynamic signaling indicates the value of the first frequency domain offset, which is 'a' times the first frequency domain unit. The first frequency domain unit is predefined by the protocol. For example, the dynamic signaling is legacy DCI signaling, and the first frequency domain unit is at least one of RE, RB, REG, and RBG.

[0391] Optional Example 1_5:

[0392] The protocol predefines the range of values ​​for the first frequency domain offset, and the semi-static signaling indicates the value of the first frequency domain offset. Its value is *a* first frequency domain units. The first frequency domain unit is predefined by the protocol. For example, the semi-static signaling is RRC signaling, and the first frequency domain unit is at least one of RE, RB, REG, and RBG.

[0393] Optional Example 1_6:

[0394] Semi-static signaling indicates the range of values ​​for the first frequency domain offset, while dynamic signaling indicates the value of the first frequency domain offset. Its value is *a* first frequency domain units. The first frequency domain unit is predefined by the protocol. For example, semi-static signaling is RRC signaling, dynamic signaling is legacy DCI, and the first frequency domain unit is at least one of RE, RB, REG, and RBG.

For example, the semi-static signaling is RRC signaling, and the first frequency domain unit is at least one of RE, RB, REG, and RBG.

[0397] Furthermore, the above methods can be used simultaneously.

[0398] Based on the above, the methods for determining the frequency domain bandwidth of the new-DCI mapping resource include at least one of the following:

[0399] Optional Example 2_1:

[0400] The protocol predefines that the size of the first frequency domain resource mapped by new-DCI is equal to the bandwidth of the data channel. For example, if the data channel is PDSCH with a bandwidth of 60 RBG, then the first frequency domain resource mapped by new-DCI is 60 RBG.

[0401] Optional Example 2_2:

[0402] The protocol predefines that the first frequency domain resource mapped by new-DCI does not exceed the bandwidth of the data channel. Furthermore, the first frequency domain resource is mapped according to the granularity of the second frequency domain resource, occupying as much of the data channel bandwidth as possible. For example, if the data channel is a PDSCH with a bandwidth of 62 RBG and the second frequency domain granularity is 6 RBG, then the size of the first frequency domain resource mapped by new-DCI is 10 second frequency domain units, or 60 RBG.

[0403] Optional Example 2_3:

[0404] The protocol predefines that the first frequency domain resource mapped by new-DCI is the bandwidth of all data channels after the first frequency domain offset. For example, if the data channel is PDSCH with a bandwidth of 62 RBG and the first frequency domain offset is 2 RBG, then the size of the first frequency domain resource mapped by new-DCI is 60 RBG.

[0405] Optional Example 2_4:

[0406] The protocol predefines that the first frequency domain resource mapped by the new-DCI is 1 / N of the bandwidth of the entire data channel, where N is an integer defined by the protocol or configured via RRC signaling. For example, if the data channel is PDSCH with a bandwidth of 48 RBG and N is 2, then the size of the first frequency domain resource mapped by the new-DCI is 24 RBG.

[0407] Optional Example 2_5:

[0408] The protocol predefines that the first frequency domain resource mapped by new-DCI is the bandwidth of all or part of the data channel, and the specific size of the first frequency domain resource is configured by signaling. The signaling includes at least one of RRC signaling, DCI, and MAC CE. For example, if the data channel is PDSCH with a bandwidth of 48 RBG, and the signaling indication is a 0110 bitmap, then the 4 RBG is divided into four parts. The second and third parts are mapped by new-DCI, while the first and fourth parts are not. The size of the first frequency domain resource is 24 RBG. For example, RRC signaling directly configures the first frequency domain resource as 24 RBG.

[0409] Furthermore, the above methods can be used simultaneously.

[0410] Based on the above, the methods for determining whether a new-DCI mapping resource is frequency-hopping in the frequency domain include at least one of the following:

[0411] Optional Example 3_1:

[0412] Frequency hopping is indicated via signaling, including RRC signaling, legacy DCI, MAC CE, etc. Example 1: The signaling contains one bit to indicate whether frequency hopping is enabled or disabled. Example 2: The signaling contains a bitmap, where each bit of each bitmap corresponds to whether the new-DCI of a time-domain symbol is frequency-hopping enabled. Example 3: The signaling contains an indicator field indicating the number of frequency hopping segments. When the indicator is 1, frequency hopping is disabled; when the indicator is 2, the first segment is not frequency-hopping, and the second segment is frequency-hopping; when the indicator is 3, the first segment is not frequency-hopping, the second segment is frequency-hopping, and the third segment is frequency-hopping; and so on.

[0413] The above methods can be combined in any way, and there are no restrictions here.

[0414] In one example, based on optional examples 1_2 and 2_3, as shown in Figure 2B, the length of a time slot in the network is 14 time-domain symbols. The PDSCH is scheduled by the legacy DCI, occupying symbols #2 to #11, which occupies 7 RBGs in the frequency domain. According to the RRC signaling configuration, the first frequency domain offset is 2. The new-DCI maps from the 3rd REG of the PDSCH in the frequency domain and continuously maps to the entire PDSCH bandwidth.

[0415] In one example, based on optional examples 1_2, 2_5, and 3_1, as shown in Figure 2C, the network time slot length is 14 time-domain symbols. The PDSCH is scheduled by the legacy DCI, occupying symbols #2 to #11, which occupy 7 RBGs in the frequency domain. According to the RRC signaling configuration, the first frequency domain offset is 2, and the first frequency domain resource is 2, with skipping enabled. The New-DCI maps from the 3rd REG of the PDSCH in the frequency domain, mapping two consecutive RBGs, and frequency hopping is enabled.

[0416] Optional embodiments

[0417] 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).

[0418] The protocol predefines support for one or more new-DCI mapping resources, which contain frequency domain resource information. New-DCI is mapped continuously in the frequency domain of the data channel, meaning it occupies contiguous frequency domain resources; or, new-DCI is mapped discretely in the frequency domain of the data channel, meaning it occupies non-contiguous frequency domain resources. The relevant configuration parameters of the new-DCI mapping resource include at least one of the following: frequency domain offset, number of frequency domain segments, frequency domain segment granularity, interval between frequency domain segments, and skipping.

[0419] Based on the above, the method for determining the first frequency domain offset of the new-DCI mapping resource includes at least one of the following:

[0420] Optional Example 1_1:

For example, the semi-static signaling is RRC signaling, and the first frequency domain unit is at least one of RE, RB, REG, and RBG.

[0430] Optional Example 1_6:

[0431] Semi-static signaling indicates the range of values ​​for the first frequency domain offset, while dynamic signaling indicates the value of the first frequency domain offset. Its value is *a* first frequency domain units. The first frequency domain unit is predefined by the protocol. For example, semi-static signaling is RRC signaling, dynamic signaling is legacy DCI, and the first frequency domain unit is at least one of RE, RB, REG, and RBG.

[0432] Optional Example 1_7:

[0433] The semi-static signaling indicates the range of values ​​for the first frequency domain offset, and the MAC CE indicates the value of the first frequency domain offset.

[0434] Furthermore, the above methods can be used simultaneously.

[0435] Based on the above, the methods for determining the number of frequency domain segments of the new-DCI mapping resource include at least one of the following:

[0436] Optional Example 2_1:

[0437] The protocol predefines at least one number of frequency bands, that is, the number of frequency domain segments of the first frequency domain resource mapped by the new-DCI is m, where m is an integer greater than 0. For example, m = 1 indicates that the new-DCI is a continuous mapping in the frequency domain; m = 2 indicates that the new-DCI is a discrete mapping of two frequency domain segments in the frequency domain.

[0438] Optional Example 2_2:

[0439] The number of frequency domain segments m of the first frequency domain resource mapped by the new-DCI is configured by signaling, where m is an integer greater than 0. The signaling includes at least one of RRC signaling, DCI, and MAC CE. For example, if the RRC signaling is configured with m=1, it indicates that the new-DCI is a continuous mapping in the frequency domain; if the RRC signaling is configured with m=2, it indicates that the new-DCI is a discrete mapping of two frequency domain segments in the frequency domain.

[0440] Furthermore, the above methods can be used simultaneously.

[0441] Based on the above, the methods for determining the frequency domain segment granularity of the new-DCI mapping resource include at least one of the following:

[0442] Optional Example 3_1:

[0443] The protocol predefines at least one frequency domain segment granularity, that is, the frequency domain segment granularity of the first frequency domain resource mapped by new-DCI is g, where g is an integer greater than 0. For example, g = 6, which means that the frequency domain segment granularity of new-DCI in the frequency domain is 6 frequency domain units.

[0444] Optional Example 3_2:

[0445] The frequency domain segment granularity *g* of the first frequency domain resource mapped by new-DCI is configured by signaling, where *g* is an integer greater than 0. The signaling includes at least one of RRC signaling, DCI, and MAC CE. For example, if the RRC signaling configuration is *g* = 6, it indicates that the frequency domain segment granularity of new-DCI in the frequency domain is 6 frequency domain units.

[0446] Furthermore, the above methods can be used simultaneously.

[0447] Based on the above, the methods for determining the frequency domain segment spacing of the new-DCI mapping resource include at least one of the following:

[0448] Optional Example 4_1:

[0449] The protocol predefines at least one frequency domain segment spacing, that is, the frequency domain segment spacing of the first frequency domain resource mapped by new-DCI is l, where l is an integer greater than 0. For example, l = 2, which means that the frequency domain segment spacing of new-DCI in the frequency domain is 2 frequency domain units.

[0450] Optional Example 4_2:

[0451] The spacing *l* between frequency domain segments of the first frequency domain resource mapped by new-DCI is configured by signaling, where *l* is an integer greater than 0. The signaling includes at least one of RRC signaling, DCI, and MAC CE. For example, if the RRC signaling configuration is *l* = 2, it indicates that the spacing between frequency domain segments of new-DCI in the frequency domain is 2 frequency domain units.

[0452] Furthermore, the above methods can be used simultaneously.

[0453] Based on the above, the methods for determining whether a new-DCI mapping resource is frequency-hopping in the frequency domain include at least one of the following:

[0454] Optional Example 5_1:

[0455] Frequency hopping is indicated via signaling, including RRC signaling, legacy DCI, MAC CE, etc. Example 1: The signaling contains one bit to indicate whether frequency hopping is enabled or disabled. Example 2: The signaling contains a bitmap, where each bit of each bitmap corresponds to whether the new-DCI of a time-domain symbol is frequency-hopping enabled. Example 3: The signaling contains an indicator field indicating the number of frequency hopping segments. When the indicator is 1, frequency hopping is disabled; when the indicator is 2, the first segment is not frequency-hopping, and the second segment is frequency-hopping; when the indicator is 3, the first segment is not frequency-hopping, the second segment is frequency-hopping, and the third segment is frequency-hopping; and so on.

[0456] The above methods can be combined in any way, and there are no restrictions here.

[0457] In one example, based on optional examples 1_2, 2_2, 3_2, 4_2, and 5_1, as shown in Figure 2C, the length of the time slot in the network is 14 time-domain symbols. The PDSCH is scheduled by the legacy DCI, occupying symbols #2 to #11, which occupy 8 RBGs in the frequency domain. According to the RRC signaling configuration, the first frequency domain offset is 1, the frequency domain segment granularity is 3, the interval between frequency domain segments is 1, and the number of frequency domain segments is 2.
