Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for channel quality reporting in wireless communication systems. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the systems. With the widespread application of 5G, new business models and new application scenarios are constantly emerging, and the existing 5G standard cannot fully meet the new demands. Therefore, 3GPP is preparing to begin preliminary research on 6G. As application scenarios become more diversified and new business models emerge, the demand for more flexible and effective use of spectrum resources is increasing daily. Therefore, 6G needs to explore new ways of using spectrum resources.

[0003] Both 4G and 5G systems support carrier aggregation (CA), which allows different frequency domain resources to be used together, increasing overall bandwidth and thus transmission rate and throughput. However, in existing 4G and 5G systems, each component carrier (CC) corresponds to a different cell, and it does not support two or more component carriers corresponding to the same cell. This approach in existing 4G and 5G systems greatly limits the spectrum flexibility in carrier aggregation, especially limiting the use of many fragmented spectrum resources. As spectrum resources (especially low-frequency spectrum resources) become increasingly valuable, 6G networks need to find a flexible and efficient way to utilize spectrum resources. The possibility of multiple carriers or spectrum distributed across multiple bands corresponding to the same cell, thus supporting uplink and downlink transmissions distributed across multiple carriers, is considered a more efficient means for 6G networks to utilize spectrum resources.

[0004] In 5G, a cell operates on a single carrier, and CSI (Channel State Information) reporting on different carriers is configured and reported separately. A Bandwidth Part (BWP) on a carrier consists of consecutive Resource Blocks (RBs). A single CSI report in 5G supports the reporting of subband channel information within the BWP. This subband channel information includes the subband Precoding Matrix Indicator (PMI) and the subband Channel Quality Indicator (CQI). To reduce the reporting overhead of subband CQI, 5G CSI reporting reports both the broadband CQI for the entire reporting band and the subband differential CQI for each subband within that reporting band. In this system, the wideband CQI indicates a modulation and a code rate, while the subband differential CQI indicates an offset level. Different values ​​of the subband differential CQI correspond to different offset levels. The offset level is equal to the subband CQI index minus the wideband CQI index. A CQI index indicates a modulation and a code rate, and an offset level is an integer or a range of integers. For details, see section 5.2.2.1 of 3GPP TS 38.214. Furthermore, in 5G CSI reporting, a CSI report on a carrier typically also reports the RI (Rank Indicator) and CRI (Channel State Information Reference Signal Resource Indicator). The reported CQI is conditional upon the RI and CRI. Summary of the Invention

[0005] The applicant's research found that independently configuring and reporting channel information from two frequency domain resources significantly increases configuration and reporting overhead. In future wireless communication systems, to utilize spectrum resources more flexibly and effectively, reporting channel information from two frequency domain resources simultaneously can greatly reduce reporting overhead, improve spectrum efficiency, and reduce terminal power consumption. Furthermore, in future wireless communication systems, the carrier configurations of the two frequency domain resources being reported together may be more flexible; in this case, how to design CQI (Channel Quality Indicator) is a key issue that needs to be addressed.

[0006] In view of the above problems, this application discloses a solution. It should be noted that the description in this application only uses multi-carrier single-cell (or single-cell multi-carrier) as a typical application scenario or example; this application is also applicable to 6G networks or other scenarios facing similar problems in the future (such as other scenarios requiring the joint use of multiple carriers, or other scenarios requiring effective utilization of fragmented spectrum, such as 2G or 3G spectrum refarming, or other scenarios utilizing idle spectrum from non-cellular systems), targeting different application scenarios, such as eMBB, URLLC, full-duplex networks, IoT, sensor networks, integrated sensing networks, and smart meters. Similar technical effects can be achieved with surface-to-surface (SBS) and terahertz networks using V2X. Furthermore, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, full-duplex networks, IoT, sensor networks, integrated sensing networks, smart metasurfaces, terahertz networks, and V2X scenarios) or different application parameters helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features used in the first node of this application can be applied to the second node of this application, and vice versa. Where there is no conflict, the embodiments and features used in the embodiments of this application can be arbitrarily combined with each other.

[0012] It should be noted that receiving (sending) information is a common expression in this field, meaning that the content of the received (sent) information is expressed in a way that is consistent with the general expression in this field.

[0013] As an example, the problem this application aims to solve includes: how to design CQI reporting for two frequency domain resources reported together, in order to utilize spectrum resources more flexibly and effectively.

[0020] The above method enables flexible CQI overhead, making it more suitable for more flexible spectrum resources in future communications and improving the flexibility of reporting overhead.

[0021] According to one aspect of this application, the condition of the carriers on which the two frequency domain resources reside includes whether the two frequency domain resources are on the same carrier; when the two frequency domain resources are on the same carrier, the plurality of candidates belong to a first candidate set; when the two frequency domain resources are on two different carriers, the plurality of candidates belong to a second candidate set; wherein,

[0022] There is a candidate in the second candidate set that is not a candidate in the first candidate set, or the number of candidates in the second candidate set is greater than the number of candidates in the first candidate set.

[0023] In the above method, different CQI candidates are used in the two cases of the same carrier and different carriers, which provides the possibility of flexible CQI candidates, is more suitable for the more flexible spectrum resources in future communications, improves the accuracy of channel quality, improves resource utilization, and enhances spectrum efficiency.

[0026] or,

[0238] Example 3

[0239] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown.

[0240] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. Layer 1 will be referred to as PHY 301 in this document. Layer 2 (L2 layer) 305, above PHY 301, is responsible for the link between the first and second communication node devices, or between two UEs. Layer 2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between logical and transport channels.

MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer).

[0250] Example 4

[0251] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. (Attached) Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0252] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0253] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0254] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In DL (Downlink), the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for L1 layer (i.e., physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and constellation mapping based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating one or more parallel... The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0255] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any parallel stream destined for the second communication device 450. Symbols on each parallel stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted over the physical channel by the first communication device 410. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2 (L2). The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the DL (Layered Logic), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 (L3) for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0256] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the first communication device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0257] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer data packets from the second communication device 450. The upper-layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0291] As one embodiment, the two carriers on the same cell include: the two carriers sharing the same SIB (system information block).

[0292] In Example 6B, the two frequency domain resources are located on two carriers, and the two carriers belong to two cells respectively.

[0293] In the appendix Figure 6B In the text, Community #1 and Community #2 are the two communities mentioned above.

[0294] As one embodiment, the two carriers are located in two separate cells, and each carrier is assigned a different cell identifier (ID).

[0295] As an example, the two carriers are respectively located on two cells: the available frequency domain resources of the two cells are respectively distributed on the two carriers.

[0296] As one embodiment, the two carriers are respectively distributed on two cells: the channels or signals in the two cells are respectively distributed on the two carriers.

[0297] As one embodiment, the two carriers are respectively located in two cells: the domains or IEs of the two carriers are configured to belong to the IEs of different cells.

[0298] Regarding the "two carriers" in Examples 6A-6B, some specific implementation methods are given below:

[0299] As one embodiment, the two frequency domain resources are located on two carriers, and the two carriers are either inter-band or intra-band non-contiguous.

[0300] As an example, each of the two carriers is a radio frequency (RF) carrier.

[0301] As an example, each of the two carriers is a baseband carrier.

[0302] As one example, each of the two carriers is a resource grid for a subcarrier interval.

[0303] As an example, each of the two carriers is a resource grid list.

[0304] As an example, each of the two carriers is a list of subcarriers spaced apart by a specific carrier.

[0305] As one example, each of the two carriers is a list of subcarriers spaced at a specific resource grid.

[0306] As one embodiment, each of the two carriers is a resource block grid or a subcarrier grid for a subcarrier interval.

[0307] As an example, each of the two carriers is a CC (component carrier).

[0308] As an example, each of the two carriers is a carrier in carrier aggregation (CA).

[0309] As an example, each of the two carriers is a carrier in Single Cell Carrier Aggregation (SCA).

[0310] As an example, each of the two carriers is a carrier in a single-cell multiple carrier.

[0311] As an example, each of the two carriers is a radio frequency channel.

[0312] As an example, each of the two carriers is a radio frequency channel after channelization.

[0313] As an example, each of the two carriers is a channel with a certain radio frequency channel bandwidth.

[0314] As one embodiment, the two carriers are inter-band.

[0315] As one embodiment, the two carriers are either inter-band or intra-band non-contiguous.

[0316] As an example, multi-carrier aggregation in a single cell only considers inter-band or discontinuous scenarios, reducing implementation and standard complexity.

[0317] As an example, two of the two carriers are contiguous within the band.

[0318] As an example, multi-carrier aggregation considers consecutive carriers even in the case of a single cell, providing greater flexibility for network deployment and carrier configuration.

[0319] As one embodiment, the two carriers include either a primary carrier or an anchor carrier.

[0320] As an example, the carrier carrying SIB1 in the two carriers is either the main carrier or the anchor carrier.

[0321] As an example, the carrier with control resource set #0 or with initial BWP (bandwidth part) among the two carriers is the primary carrier or the anchor carrier.

[0322] As an example, one of the two carriers having a synchronization signal, a master information block, a system information block, a control resource set #0, and a common search space is a master carrier or an anchor carrier.

[0323] As an example, both carriers belong to the same frequency range (FR).

[0324] As an example, both carriers belong to frequency range 1 (FR1).

[0325] As an example, restricting the two carriers to the same frequency range (at least in the initial version) effectively utilizes the existing main fragmented spectrum while reducing implementation complexity.

[0326] As one example, the two carriers belong to different frequency ranges.

[0327] As an example, the two carriers are allowed to belong to different frequency ranges, which improves flexibility while ensuring forward compatibility.

[0328] As an example, the same mathematical structure is used on the two carriers.

[0329] As an example, the same subcarrier spacing is used on the two carriers.

[0330] As an example, restricting two carriers to use the same subcarrier spacing simplifies scheduling design.

[0331] As one example, two of the two carriers employ different subcarrier spacings.

[0332] As one example, it allows two carriers to use different subcarrier spacings, increasing flexibility and supporting a wider spectrum range.

[0421] Examples 10A-10B

[0422] Examples 10A-10B illustrate schematic diagrams of a first CQI and a plurality of candidates according to an embodiment of this application, respectively; as shown in the attached figures. Figures 10A-10B As shown.

[0423] In Example 10A, each of the plurality of candidates includes a modulation and a code rate; the first CQI for at least one of the two frequency domain resources includes: the first CQI for the entire reporting frequency band of the first report, wherein,

[0424] The first reported frequency band includes the two frequency domain resources, and each of the two frequency domain resources includes one or more sub-bands;

[0425] or,

[0426] The first reported frequency band includes at least one sub-band in each of the two frequency domain resources.

[0427] In the appendix Figure 10A The example illustrates an N-bit CQI table, where a CQI index (i.e., the value of an N-bit CQI) indicates a modulation and a code rate; the first CQI comprises N bits, and the first CQI from the N-bit CQI table indicates the modulation and code rate for the entire reporting band (also commonly referred to as wideband CQI) of the first report.

[0428] In Example 10B, the first CQI for at least one of the two frequency domain resources includes: the first CQI is a subband differential CQI for one subband of the two frequency domain resources, and the plurality of candidates are different offset levels.

[0429] In the appendix Figure 10B The example illustrates a mapping table from subband differential CQI values ​​to offset levels, where different subband differential CQI values ​​indicate different offset levels; the first CQI comprises N bits and indicates the offset level for one subband of the two frequency domain resources from the mapping table.

[0430] As one embodiment, the first report includes a wideband CQI, the wideband CQI targeting the entire reporting frequency band of the first report; the first CQI is a subband differential CQI targeting one subband of the two frequency domain resources, and the plurality of candidates are different offset levels; the offset level indicated by the first CQI is equal to the CQI index of the subband targeted by the first CQI minus the wideband CQI index; wherein,

[0431] The first reported frequency band includes the two frequency domain resources, and each of the two frequency domain resources includes one or more sub-bands;

[0432] or,

[0437] Example 11

[0438] Example 11 illustrates a schematic diagram of a scenario where multiple candidates depend on carriers containing two frequency domain resources according to an embodiment of this application; as shown in the attached diagram. Figure 11 As shown.

[0439] In Example 11, the situation regarding the carriers on which the two frequency domain resources reside includes whether the two frequency domain resources are on the same carrier; when the two frequency domain resources are on the same carrier, the plurality of candidates belong to a first candidate set; when the two frequency domain resources are on two different carriers, the plurality of candidates belong to a second candidate set; wherein,

[0440] There is a candidate in the second candidate set that is not a candidate in the first candidate set, or the number of candidates in the second candidate set is greater than the number of candidates in the first candidate set.

[0441] In the appendix Figure 11 In Case A, where the two frequency domain resources are on the same carrier, the first CQI is used to indicate a candidate from the first candidate set. In Case B, where the two frequency domain resources are on two different carriers, the first CQI is used to indicate a candidate from the second candidate set.

[0442] The following provides specific implementation methods for the first candidate set and the second candidate set, focusing on the first CQI indication modulation and code rate in Embodiment 10A:

[0443] As an example, each candidate in the first candidate set includes a modulation and a code rate, and each candidate in the second candidate set includes a modulation and a code rate; there is one candidate in the second candidate set that is different from each candidate in the first candidate set.

[0444] As an example, each candidate in the first candidate set includes a modulation and a code rate, and each candidate in the second candidate set includes a modulation and a code rate; the number of candidates in the second candidate set is greater than the number of candidates in the first candidate set.

[0445] As an example, each candidate in the first candidate set includes a modulation and a code rate, and each candidate in the second candidate set includes a modulation and a code rate; the maximum efficiency of the candidates in the second candidate set is different from the maximum efficiency of the candidates in the first candidate set.

[0446] As an example, each candidate in the first candidate set includes a modulation and a code rate, and each candidate in the second candidate set includes a modulation and a code rate; the minimum efficiency of the candidates in the second candidate set is different from the minimum efficiency of the candidates in the first candidate set.

[0447] In the above method, different CQI tables are used in the two cases of the same carrier and different carriers. For example, they can have the same size but different combinations of modulation and code rate, or they can have different sizes. This can be well applied to more flexible spectrum resources in future communications, improve the accuracy of channel quality reporting, improve reliability and robustness, and improve the system spectrum efficiency.

[0448] The following provides specific implementation methods for the first candidate set and the second candidate set for the first CQI indication offset level in Example 10B:

[0449] As an example, each candidate in the first candidate set is an offset level, and each candidate in the second candidate set is an offset level; there is an offset level in the second candidate set that is different from each offset level in the first candidate set.

[0450] As an example, each candidate in the first candidate set is an offset level, and each candidate in the second candidate set is an offset level; the number of offset levels in the second candidate set is greater than the number of offset levels in the first candidate set.

[0451] As an example, each candidate in the first candidate set is an offset level, and each candidate in the second candidate set is an offset level, where an offset level is an integer or an integer range; the number of integer offset levels in the second candidate set is greater than the number of integer offset levels in the first candidate set.

[0452] As an example, the candidates in the first candidate set are 0, 1, ≥2, ≤-1; and the candidates in the second candidate set are 0, 1, 2, 3, -1, -2, ≥4, ≤-3.

[0453] As an example, the candidates in the first candidate set are 0, 1, ≥2, ≤-1; and some of the candidates in the second candidate set are 0, 1, 2, 3, -1, -2, ≥4, ≤-3.

[0454] As an example, the first CQI includes N bits, where N depends on the carriers on which the two frequency domain resources are located, and N is a positive integer; when the two frequency domain resources are on the same carrier, N is 2; when the two frequency domain resources are on two different carriers, N is greater than 2.

[0455] In the above method, different subband differential CQI tables are used in the two cases of the same carrier and different carriers. For example, they can have the same size but different offset levels, or they can have different sizes.
