Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus with multiple antennas in wireless communication. 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 system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study New Radio (NR) (or 5G). At the 3GPP RAN #75 plenary meeting, the WI (Work Item) for New Radio (NR) was adopted, and the standardization work for NR began.

[0003] In New Radio (NR) technologies, multi-antenna technologies (such as Multiple Input Multiple Output (MIMO), Transmission Reception Point (TRP), and multiple panels) are crucial components. To adapt to more diverse application scenarios and meet higher demands, the 3GPP RAN#86 plenary meeting approved a further enhancement of MIMO under NR, WI, to support more robust, spectrally efficient, and versatile multi-antenna communication for a wider range of applications. Summary of the Invention

[0004] In multi-antenna systems, such as multiple transmission reception point (TRP) communication, the same channel or signal can be transmitted through multiple transmission reception points to enhance transmission robustness. Release 16 (Rel-16) supported multi-transmission reception point transmission for data channels, and 3GPP plans to introduce multi-transmission reception point transmission for control channels in Release 17 (Rel-17). In Release 16, the data channel (PDSCH) needs to avoid the resources occupied by the corresponding scheduling channel during resource mapping. Accordingly, the resource mapping of the data channel also needs to consider supporting the transmission of control channels across multiple TRPs or panels.

[0005] This application discloses a solution to the problems of control channel transmission and resource mapping in multi-antenna systems. It should be noted that the description in this application uses a multi-antenna system, particularly a multi-transmitter / receiver node transmission system, as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (such as scenarios with higher requirements for control channel robustness or coverage, or scenarios requiring PDCCH association in addition to multi-transmitter / receiver node transmission, including but not limited to coverage enhancement systems, IoT (Internet of Things), URLLC (Ultra-Reliable Low Latency Communication) networks, and vehicle-to-everything (V2X) networks), and can achieve similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to multi-antenna system scenarios) helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the first node device of this application can be applied to the second node device, and vice versa. In particular, the interpretation of terms, nouns, functions and variables in this application (unless otherwise specified) can be found in the definitions in the 3GPP specification protocols TS36, TS38 and TS37 series.

[0006] This application discloses a method for a first node in wireless communication, characterized by comprising:

[0007] A first information block is received, which is used to determine a first search space set and a second search space set. The first search space set includes at least one PDCCH candidate, and the second search space set includes at least one PDCCH candidate. The PDCCH candidates included in the first search space set and the PDCCH candidates included in the second search space set are correspondingly associated.

[0008] The system receives target control signaling and a first PDSCH, the target control signaling being used to determine a target time-frequency resource set; the time-frequency resources occupied by the first PDSCH belong to the target time-frequency resource set.

[0009] Wherein, the first PDCCH is used to carry the target control signaling, the first PDCCH is a PDCCH candidate included in the first search space set, and the second PDCCH is a PDCCH candidate included in the second search space set; the first search space set and the second search space set are different, and the aggregation level of the first PDCCH and the aggregation level of the second PDCCH are not equal; whether the first PDCCH is detected is used to determine whether the resources occupied by the second PDCCH are valid for the first PDSCH.

[0010] As an example, the resource occupied by the second PDCCH is determined to be valid for the first PDSCH by whether the first PDCCH is detected. Thus, when mapping the PDSCH resources, the associated PDCCH candidates and PDCCH candidates that have the possibility of early termination or early decoding with the associated PDCCH candidates are considered at the same time. This avoids collisions between PDSCH and PDCCH, especially collisions caused by the inconsistency in the understanding of PDCCH candidates between the base station and user equipment, and ensures the transmission performance of PDSCH.

[0011] According to one aspect of this application, the above method is characterized in that the control resource set associated with the first search space set is a first control resource set, and the control resource set associated with the second search space set is a second control resource set; the quasi-co-addressable PDCCH reference signals whose resources belong to the first control resource set and the quasi-co-addressable PDCCH reference signals whose resources belong to the second control resource set are not the same; the target reference resource set includes all resources occupied by PDCCH reference signals in the first control resource set and all resources occupied by PDCCH reference signals in the second control resource set; and the precoding granularity of the first control resource set is used to determine whether all resources included in the target reference resource set are invalid for the first PDSCH.

[0012] As an example, the precoding granularity of the first control resource set is used to determine whether all resources of the target reference resource set are invalid for the first PDSCH. Thus, when mapping resources in the PDSCH, the PDCCH DMRS in the two related CORESETs are considered together. When the precoding in both CORESETs uses all RBs, as long as one PDCCH candidate is detected among the related PDCCH candidates, the PDSCH will perform rate matching on all PDCCH DMRS in the two CORESETs, avoiding collisions between the PDSCH and PDCCH DMRS, and further ensuring the transmission performance of the PDSCH.

[0013] According to one aspect of this application, the method is characterized in that the third PDCCH is a PDCCH candidate included in the second search space set and associated with the first PDCCH, the aggregation level of the first PDCCH is equal to the aggregation level of the third PDCCH, the index of the first PDCCH in the first search space set is equal to the index of the third PDCCH in the second search space set; the starting CCE occupied by the third PDCCH is the same as the starting CCE occupied by the second PDCCH, and whether the first PDCCH is detected is used to determine whether the resources occupied by the third PDCCH are valid for the first PDSCH.

[0014] According to one aspect of this application, the above method is characterized in that the target value is equal to the total number of monitoring operations performed on two mutually associated PDCCH candidates, the target value being a positive integer; the target value is used to determine whether the resources occupied by the second PDCCH are valid for the first PDSCH.

[0015] As an example, the resource occupied by the second PDCCH is determined based on the target value to see if it is avoided by the first PDSCH. This allows for the determination of whether the PDCCH resource is actually occupied based on the blind detection of the PDCCH, thereby reducing unnecessary rate matching or puncturing during PDSCH resource mapping and improving resource utilization and PDSCH transmission performance.

[0016] According to one aspect of this application, the method is characterized in that at least one of the PDCCH candidates or the second PDCCH included in the second search space set and associated with the first PDCCH is monitored to determine whether the resources occupied by the second PDCCH are valid for the first PDCCH.

[0017] As an example, the resource occupied by the second PDCCH is rate-matched by the first PDSCH based on whether at least one of the PDCCH alternative associated with the first PDCCH or the second PDCCH is monitored or discarded. Thus, when the PDCCH is discarded or not monitored, even if the associated PDCCH alternative is detected, the PDSCH resource mapping still does not require rate matching for the discarded PDCCH, ensuring the coding efficiency of PDSCH transmission and improving transmission performance.

[0018] According to one aspect of this application, the above method is characterized in that the control resource set associated with the first search space set includes only one symbol in the time domain, and the control resource set associated with the second search space set includes only one symbol in the time domain; the CCE-to-REG mapping used by the control resource set associated with the first search space set is non-interleaved, and the CCE-to-REG mapping used by the control resource set associated with the second search space set is non-interleaved; the aggregation level of the second PDCCH is equal to twice the aggregation level of the first PDCCH.

[0019] According to one aspect of this application, the method is characterized in that at least one symbol occupied by the second PDCCH in the time domain belongs to a first time window, and one subcarrier occupied by the second PDCCH in the frequency domain belongs to a first BWP; a first threshold is equal to the maximum number of PDCCH candidate monitoring times by the receiver of the target control signaling within the first time window and on the first BWP, and the first threshold is a positive integer; a second threshold is equal to the maximum number of non-overlapping CCEs occupied by the PDCCH candidates monitored by the receiver of the target control signaling within the first time window and on the first BWP, and the second threshold is a positive integer; the index of the second search space set, the first threshold, and the second threshold are used together to determine whether the second search space set is monitored in the first time window.

[0030] This application discloses a first node device for wireless communication, characterized in that it includes:

[0031] A first receiver receives a first information block, which is used to determine a first search space set and a second search space set. The first search space set includes at least one PDCCH candidate, and the second search space set includes at least one PDCCH candidate.

The first search space set includes at least one PDCCH candidate, and the second search space set includes at least one PDCCH candidate.

(Attached) Figure 2This diagram illustrates the network architecture 200 of 5G NR, LTE (Long-Term Evolution), and LTE-A (Long-Term Evolution Advanced) systems. The 5G NR or LTE network architecture 200 may be referred to as 5GS (5G System) / EPS (Evolved Packet System) 200 or some other suitable term. 5GS / EPS 200 may include one or more UE (User Equipment) 201, NG-RAN (Next Generation Radio Access Network) 202, 5GC (5G Core Network) / EPC (Evolved Packet Core) 210, HSS (Home Subscriber Server) / UDM (Unified Data Management) 220, and Internet services 230. 5GS / EPS can interconnect with other access networks, but these entities / interfaces are not shown for simplicity. As shown in the figure, 5GS / EPS provides packet-switched services; however, those skilled in the art will readily understand that the various concepts presented throughout this application can be extended to networks providing circuit-switched services or other cellular networks. NG-RAN includes NR / Evolved Node B (gNB / eNB) 203 and other gNBs (eNBs) 204. gNBs (eNBs) 203 provide user and control plane protocol termination to UE 201. gNBs (eNBs) 203 can connect to other gNBs (eNBs) 204 via Xn / X2 interfaces (e.g., backhaul). gNBs (eNBs) 203 may also be referred to as a base station, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), TRP (Transmitter Receiver Node), or some other suitable terminology. gNBs (eNBs) 203 provide UE 201 with an access point to the 5GC / EPC 210. Examples of UE201 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, non-terrestrial base station communications, satellite mobile communications, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, drones, aircraft, narrowband IoT devices, machine-type communication devices, land vehicles, automobiles, wearable devices, or any other similar functional devices.Those skilled in the art may also refer to UE201 as a mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or any other suitable term. gNB (eNB)203 connects to 5GC / EPC210 via the S1 / NG interface. 5GC / EPC210 includes MME (Mobility Management Entity) / AMF (Authentication Management Field) / SMF (Session Management Function) 211, other MME / AMF / SMF 214, S-GW (Service Gateway) / UPF (User Plane Function) 212, and P-GW (Packet Data Network Gateway) / UPF 213. The MME / AMF / SMF211 is the control node that handles signaling between UE201 and 5GC / EPC210. ​​Essentially, the MME / AMF / SMF211 provides bearer and connection management. All user IP (Internet Protocol) packets are transmitted through the S-GW / UPF212, which is itself connected to the P-GW / UPF213. The P-GW provides UE IP address allocation and other functions. The P-GW / UPF213 is connected to Internet service 230.

[0317] Example 3

[0318] 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 node device (UE or gNB) and the second node device (gNB or UE) 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. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second node devices via PHY301. L2 layer 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 node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encrypted data packets and supports cross-regional mobility between the second node devices and the first node device. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among first-node devices. 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-node devices and the first-node devices. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for the first and second node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS flows and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the first node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0319] As an example, Appendix Figure 3 The wireless protocol architecture described herein is applicable to the first node device in this application.

[0320] As an example, Appendix Figure 3 The wireless protocol architecture described herein is applicable to the second node device in this application.

[0322] As an example, the target control signaling in this application is generated in the RRC306, or MAC302, or MAC352, or PHY301, or PHY351.

[0323] As an example, the first PDSCH in this application is generated in RRC306, or MAC302, or MAC352, or PHY301, or PHY351.

[0324] Example 4

[0325] Example 4 illustrates a schematic diagram of a first node device and a second node device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown.

[0326] The first node device (450) may include a controller / processor 490, a data source / buffer 480, a receiver processor 452, a transmitter / receiver 456 and a transmitter processor 455, wherein the transmitter / receiver 456 includes an antenna 460.

[0327] The second node device (410) may include a controller / processor 440, a data source / buffer 430, a receiver processor 412, a transmitter / receiver 416 and a transmitter processor 415, wherein the transmitter / receiver 416 includes an antenna 420.

[0328] In the DL (Downlink) process, upper-layer packets, such as the higher-layer information included in the first information block and the first PDSCH in this application, are provided to the controller / processor 440. The controller / processor 440 implements L2 and higher-layer functions. In the DL process, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for the first node device 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first node device 450, such as the higher-layer information included in the first information block and the first PDSCH in this application, which are all generated in the controller / processor 440. The transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including encoding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation. For example, the generation of the physical layer signal of the first information block and the physical layer signal of the first PDSCH in this application is completed in the transmit processor 415, as is the generation of the target control signaling. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol. Then, the transmit processor 415 maps the mapping to the antenna 420 via the transmitter 416 and transmits it as a radio frequency signal. At the receiving end, each receiver 456 receives the radio frequency signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receiver processor 452. The receiver processor 452 implements various signal reception processing functions for the L1 layer. The signal reception and processing function includes receiving the physical layer signals of the first information block and the first PDSCH in this application, as well as the target control signaling in this application. It demodulates the multi-carrier symbols in the multi-carrier symbol stream using various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)), followed by descrambling, decoding, and deinterleaving to recover the data or control transmitted by the second node device 410 on the physical channel. The data and control signals are then provided to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and interprets the higher-level information included in the first information block and the first PDSCH in this application. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as computer-readable media.

Each rectangle filled with intersecting lines represents the resources included in the target reference resource set. The dotted parts represent the resources occupied by the first PDCCH, and the gray-filled parts represent the resources occupied by the PDCCH alternatives associated with the first PDCCH. The dashed lines with arrows represent the association relationships.

[0356] As an example, information blocks belonging to the same IE as the first information block in this application, other than the first information block, are used to indicate the control resource set (CORESET) associated with the second search space set.

[0366] As one embodiment, the first control resource set employs an interleaved CCE-to-REG mapping, and the second control resource set employs an interleaved CCE-to-REG mapping.

[0367] As an example, the first control resource set uses a non-interleaved CCE-to-REG mapping, and the second control resource set uses a non-interleaved CCE-to-REG mapping.

[0368] As one embodiment, the number of rows in the interleaver of the first control resource set is equal to the number of rows in the interleaver of the second control resource set.

[0370] As an example, the configurations outside the quasi-co-location (QCL) of the first control resource set are the same as the configurations outside the quasi-co-location of the second control resource set.

[0371] As an example, the PDCCH reference signal occupying resources belonging to the first control resource set is the PDCCH (Physical Downlink Control Channel) DMRS (Demodulation Reference Signal), and the PDCCH reference signal occupying resources belonging to the second control resource set is the PDCCH DMRS.

[0372] As an example, the PDCCH reference signal whose resource occupies the first control resource set is at least one PDCCH candidate reference signal included in the first control resource set, and the PDCCH reference signal whose resource occupies the second control resource set is at least one PDCCH candidate reference signal included in the second control resource set.

[0388] As one embodiment, the first transceiver receives a second information block, wherein the second information block is used to determine a target standard co-address set, the target standard co-address set including a positive integer number of antenna port quasi-co-addresses greater than 1, the quasi-co-address of the PDCCH reference signal whose resources belong to the first control resource set is an antenna port quasi-co-address included in the target standard co-address set, and the quasi-co-address of the PDCCH reference signal whose resources belong to the second control resource set is an antenna port quasi-co-address included in the target standard co-address set. As a supplementary embodiment of the above embodiment, the second information block and the first information block are different. As a supplementary embodiment of the above embodiment, the second information block and the first information block are the same. As a supplementary embodiment of the above embodiment, the second information block and the first information block are two different IEs or domains in the same signaling.

[0389] As an example, the statement in the claim that "the quasi-co-addressable PDCCH reference signals whose resources belong to the first control resource set and the quasi-co-addressable PDCCH reference signals whose resources belong to the second control resource set are not the same" includes the following meaning: the index value of the control resource set resource pool (CORESETPool) to which the first control resource set belongs and the index value of the control resource set resource pool (CORESETPool) to which the second control resource set belongs are not equal.

[0390] As an example, the index value of the control resource set resource pool (CORESETPool) to which the first control resource set belongs is not equal to the index value of the control resource set resource pool (CORESETPool) to which the second control resource set belongs.

[0391] As an example, the index value of the control resource set resource pool (CORESETPool) to which the first control resource set belongs is equal to the index value of the control resource set resource pool (CORESETPool) to which the second control resource set belongs.

[0392] As one embodiment, the target reference resource set includes all REs occupied by the PDCCH reference signal in the first control resource set and all REs occupied by the PDCCH reference signal in the second control resource set.

[0393] As an example, any RE occupied by the PDCCH reference signal included in the first control resource set belongs to the target reference signal resource set, and any RE occupied by the PDCCH reference signal included in the second control resource set belongs to the target reference signal resource set.

[0394] As an example, the target reference resource set includes only all resources occupied by the PDCCH reference signal in the first control resource set and all resources occupied by the PDCCH reference signal in the second control resource set.

[0395] As an example, the target reference resource set also includes all resources occupied by the PDCCH reference signal in the first control resource set or all resources occupied by the PDCCH reference signal in the second control resource set.

[0396] As an example, all resources occupied by the PDCCH reference signal in the first control resource set are all REs occupied by the PDCCH reference signal in the first control resource set, and all resources occupied by the PDCCH reference signal in the second control resource set are all REs occupied by the PDCCH reference signal in the second control resource set.

[0398] As one embodiment, all resources occupied by the PDCCH reference signal in the first control resource set and all resources occupied by the PDCCH reference signal in the second control resource set together constitute the target reference resource set.

[0399] As an example, the first information block is used to indicate the precoding granularity of the first control resource set.

[0400] As an example, information blocks other than the first information block are used to indicate the precoding granularity of the first control resource set.

[0401] As an example, information blocks other than the first information block that belong to the same IE as the first information block are used to indicate the precoding granularity of the first control resource set.

[0402] As an example, the precoding granularity of the first control resource set is the same as that of the second control resource set.

[0403] As an example, the precoding granularity of a control resource set (CORESET) is a resource unit within the control resource set that is assumed to use the same precoding.

[0404] As one embodiment, the precoding granularity of the first control resource set is one of REG bundles or all consecutive RBs (Resource Blocks), and the precoding granularity of the second control resource set is one of REG bundles or all consecutive RBs (Resource Blocks); the precoding granularity of the first control resource set and the precoding granularity of the second control resource set are the same.

[0406] As an example, the statement in the claim that "the precoding granularity of the first control resource set is used to determine whether all resources included in the target reference resource set are invalid for the first PDSCH" includes the following meaning: the precoding granularity of the first control resource set is used as one of a plurality of conditions to indirectly or directly determine whether all resources included in the target reference resource set are invalid for the first PDSCH.

[0407] As an example, the statement in the claim that "the precoding granularity of the first control resource set is used to determine whether all resources included in the target reference resource set are invalid for the first PDSCH" includes the following meaning: the precoding granularity of the first control resource set is used based on conditional relations to determine whether all resources included in the target reference resource set are invalid for the first PDSCH.

[0408] As an example, the statement in the claim that "the precoding granularity of the first control resource set is used to determine whether all resources included in the target reference resource set are invalid for the first PDSCH" includes the following meanings: when the precoding granularity of the first control resource set is all consecutive RBs, all resources included in the target reference resource set are invalid for the first PDSCH; when the precoding granularity of the first control resource set is REG bundling, some resources included in the target reference resource set are invalid for the first PDSCH.

[0409] As an embodiment, the statement in the claim that "the precoding granularity of the first control resource set is used to determine whether all resources included in the target reference resource set are invalid for the first PDSCH" includes the following meanings: when the precoding granularity of the first control resource set is all consecutive RBs, all resources included in the target reference resource set are invalid for the first PDSCH; when the precoding granularity of the first control resource set is REG bundling, the resources occupied by the only PDCCH reference signals of the target reference resource set that are detected to carry the target control signaling are invalid for the first PDSCH.

[0410] As an embodiment, the statement in the claim that "the precoding granularity of the first control resource set is used to determine whether all resources included in the target reference resource set are invalid for the first PDSCH" includes the following meanings: when the precoding granularity of the first control resource set is all consecutive RBs, all resources included in the target reference resource set are invalid for the first PDSCH; when the precoding granularity of the first control resource set is REG bundling, the resources occupied by the PDCCH reference signal that is detected carrying the target control signaling PDCCH candidate are invalid for the first PDSCH.

[0411] Example 7

[0412] Example 7 illustrates a schematic diagram of the relationship between the second PDCCH and the third PDCCH according to an embodiment of this application, as shown in the attached diagram. Figure 7 As shown. In the appendix Figure 7In the diagram, in cases A and B, the horizontal axis represents time, and the vertical axis represents frequency. In each case, the thick-lined rectangle represents the second PDCCH, the rectangle filled with crosshairs represents the first PDCCH, the rectangle filled with intersecting lines represents the third PDCCH, and the dashed lines with arrows represent interrelationships. In case A, the first and third PDCCHs are time-division multiplexed; in case B, the first and third PDCCHs are frequency-division multiplexed.

[0413] In Embodiment 7, the third PDCCH is a PDCCH candidate included in the second search space set of this application and associated with the first PDCCH of this application. The aggregation level of the first PDCCH is equal to the aggregation level of the third PDCCH. The index of the first PDCCH in the first search space set of this application is equal to the index of the third PDCCH in the second search space set. The starting CCE occupied by the third PDCCH is the same as the starting CCE occupied by the second PDCCH. Whether the first PDCCH is detected is used to determine whether the resources occupied by the third PDCCH are valid for the first PDSCH of this application.

[0414] As an example, the first node device in this application assumes that the third PDCCH is used to carry the target control signaling.

[0415] As an example, the time-frequency resources occupied by the third PDCCH are different from those occupied by the first PDCCH.

[0416] As an example, the index of the control resource set resource pool to which the third PDCCH belongs (CORESETpool index) is not equal to the index of the control resource set resource pool to which the first PDCCH belongs.

[0417] As an example, the third PDCCH was not detected, while the first PDCCH was detected.

[0418] As an example, the third PDCCH is detected.

[0419] As an example, the first node device in this application assumes that the scrambling code of the third PDCCH is different from the scrambling code of the first PDCCH.

[0420] As an example, blind detection of the target control signaling performed only on the third PDCCH fails.

[0421] As an example, blind PDCCH detection performed only on the third PDCCH fails, while blind PDCCH detection performed only on the first PDCCH alternative succeeds.

[0422] As an example, a blind PDCCH detection performed only on the third PDCCH fails, a blind PDCCH detection performed only on the first PDCCH fails, and a blind PDCCH detection performed jointly (or merged or soft-merged) on the third PDCCH and the first PDCCH succeeds.

[0423] As an example, a blind PDCCH detection performed only on the third PDCCH fails, a blind PDCCH detection performed only on the first PDCCH succeeds, and a blind PDCCH detection performed jointly (or merged or soft-merged) on the third PDCCH and the first PDCCH fails.

[0424] As an example, decoding or blind detection of the target control signaling performed only on the third PDCCH fails, while decoding or blind detection of the target control signaling performed only on the first PDCCH alternative succeeds.

[0425] As an example, decoding or blind detection of the target control signaling performed only on the third PDCCH fails, decoding or blind detection of the target control signaling performed only on the first PDCCH fails, and decoding or blind detection of the target control signaling performed jointly (or merged or soft-merged) on the third PDCCH and the first PDCCH succeeds.

[0426] As an example, decoding or blind detection of the target control signaling performed only on the third PDCCH fails, decoding or blind detection of the target control signaling performed only on the first PDCCH succeeds, and decoding or blind detection of the target control signaling performed jointly (or merged or soft-merged) on the third PDCCH and the first PDCCH fails.

[0427] As an example, only the decoding or blind detection of the target control signaling performed on the third PDCCH fails (or the CRC check fails), while the decoding or blind detection of the target control signaling performed on at least the first PDCCH (either the first PDCCH or the third PDCCH) succeeds (or the CRC check passes).

[0428] As an example, the first node device in this application only fails to detect the target control signaling on the third PDCCH.

[0429] As an example, the third PDCCH is a PDCCH alternative monitored by the first node device.

[0430] As an example, the target control signaling is actually transmitted on the third PDCCH.

[0431] As an example, the target control signaling was not actually sent on the third PDCCH.

[0432] As an example, the first node device in this application assumes that the target control signaling is sent on the third PDCCH.

[0433] As an example, the first node device in this application assumes that the third PDCCH and the first PDCCH are two repeated transmissions of the target control signaling.

[0434] As an example, the first node device in this application assumes that the third PDCCH and the first PDCCH are two repeated transmissions of the same PDCCH carrying the target control signaling.

[0435] As an example, the third PDCCH and the first PDCCH are two corresponding PDCCH candidates in the first search space set and the second search space set, respectively.

[0436] As an example, the first node device in this application assumes that soft merging is possible between the first PDCCH and the third PDCCH.

[0437] As an example, the first node device in this application assumes that soft merging is not possible between the first PDCCH and the third PDCCH.

[0438] As an example, the first information block is used to indicate whether the first node device in this application can assume that soft merging is possible between the first PDCCH and the third PDCCH.

[0439] As an example, information blocks other than the first information block that belong to the same IE as the first information block are used to indicate whether the first node device in this application can assume that soft merging can be performed between the first PDCCH and the third PDCCH.

[0440] As an example, the index of the first PDCCH in the first search space set is a non-negative integer, and the index of the third PDCCH in the second search space set is a non-negative integer.

[0441] As one embodiment, the PDCCH candidates included in the first search space set are indexed sequentially according to predefined rules, and the PDCCH candidates included in the second search space set are indexed sequentially according to predefined rules.

[0442] As an example, the aggregation level of the first PDCCH and the aggregation level of the third PDCCH are both equal to the target aggregation level. The index of the first PDCCH in the first search space set is the index of the first PDCCH in the first search space set that is a candidate PDCCH with the target aggregation level. The index of the third PDCCH in the second search space set is the index of the third PDCCH in the second search space set that is a candidate PDCCH with the target aggregation level.

[0443] As one embodiment, the PDCCH candidates included in the first search space set are indexed sequentially according to their occupied starting CCE, and the PDCCH candidates included in the second search space set are indexed sequentially according to their occupied starting CCE.

[0444] As an example, the index of the first PDCCH in the first search space set is the index of the first PDCCH. The value of the third PDCCH, and the index of the third PDCCH in the second search space set is the value of the third PDCCH. The value of .

[0445] As an example, the index value of the starting CCE occupied by the third PDCCH is equal to the index value of the starting CCE occupied by the second PDCCH.

[0446] As an example, the index value of the starting CCE occupied by the third PDCCH in its respective control resource set is equal to the index value of the starting CCE occupied by the second PDCCH in its respective control resource set.

[0447] As an example, the CCE with the smallest index value occupied by the third PDCCH and the CCE with the smallest index value occupied by the second PDCCH are the same CCE.

[0448] As an example, the index value of the CCE with the smallest index value occupied by the third PDCCH in its control resource set is equal to the index value of the CCE with the smallest index value occupied by the second PDCCH in its control resource set.

[0449] As an example, the second PDCCH occupies any one of the CCEs occupied by the third PDCCH.

[0450] As an example, any CCE occupied by the third PDCCH is also occupied by the second PDCCH.

[0451] As an example, the third PDCCH and the second PDCCH support early termination or early decoding after the third PDCCH is detected.

[0513] Example 10

[0514] Example 10 illustrates a schematic diagram of a control resource set associated with a first search space set and a control resource set associated with a second search space set according to an embodiment of this application, as shown in the attached diagram. Figure 10 As shown. In the appendix Figure 10 In the diagram, the horizontal axis represents frequency, the vertical axis represents time, and the two thick rectangles represent the control resource sets associated with the first search space set and the control resource sets associated with the second search space set, respectively. The number in each rectangle represents the index of the REG in its respective control resource set, and REGs with the same padding form the same CCE.

[0515] In Embodiment 10, the control resource set associated with the first search space set in this application includes only one symbol in the time domain, and the control resource set associated with the second search space set in this application includes only one symbol in the time domain; the CCE to REG mapping used by the control resource set associated with the first search space set is non-interleaved, and the CCE to REG mapping used by the control resource set associated with the second search space set is non-interleaved; the aggregation level of the second PDCCH in this application is equal to twice the aggregation level of the first PDCCH in this application.

[0516] As an example, the first control resource set in this application includes only one symbol in the time domain, and the second control resource set in this application includes only one symbol in the time domain.

[0517] As an example, the duration of the control resource set associated with the first search space set in the time domain is equal to the duration of one symbol, and the duration of the control resource set associated with the second search space set in the time domain is equal to the duration of one symbol.

[0520] As an example, information blocks other than the first information block in this application that belong to the same IE as the first information block are used to explicitly or implicitly indicate the number of symbols included in the control resource set associated with the first search space set in the time domain and the number of symbols included in the control resource set associated with the second search space set in the time domain.

[0527] Example 11

[0528] Example 11 illustrates a schematic diagram of the relationship between a second search space set and a first threshold and a second threshold according to an embodiment of this application, as shown in the attached diagram. Figure 11 As shown. In the appendix Figure 1 In the diagram, the horizontal axis represents time, and each thick-lined rectangle represents a search space set, a0, a1, a2, ..., a jThese represent the number of PDCCH monitoring times in the corresponding search space set, b0, b1, b2, ..., b j These represent the number of non-overlapping CCEs occupied by the PDCCH candidates monitored in the corresponding search space set; where b0+b1≤second threshold and a0+a1≤first threshold, and a0+a1+a2≥first threshold or b0+b1+b2≥second threshold.

[0529] In Embodiment 11, at least one symbol occupied by the second PDCCH in the time domain belongs to a first time window, and one subcarrier occupied by the second PDCCH in the frequency domain belongs to a first BWP; the first threshold is equal to the maximum number of PDCCH candidate monitoring times by the receiver of the target control signaling within the first time window and on the first BWP, and the first threshold is a positive integer; the second threshold is equal to the maximum number of non-overlapping CCEs occupied by the PDCCH candidates monitored by the receiver of the target control signaling within the first time window and on the first BWP, and the second threshold is a positive integer; the index of the second search space set, the first threshold, and the second threshold are used together to determine whether the second search space set is monitored in the first time window.

[0530] As one embodiment, the first time window is a slot, a subframe, or a span.

[0531] As an example, the first time window is a time window for a subcarrier spacing (SCS).

[0532] As one embodiment, the first time window includes at least one time-domain continuous symbol.

[0533] As an example, any symbol occupied by the second PDCCH in the time domain belongs to the first time window.

[0534] As an example, the symbol occupied by the second PDCCH in the time domain belongs to outside the first time window.

[0535] As an example, any symbol occupied by the second PDCCH in the time domain is an OFDM symbol.

[0536] As an example, any symbol occupied by the second PDCCH in the time domain includes a cyclic prefix and a data portion.

[0537] As an example, the second PDCCH occupies at least one symbol in the time domain and at least one subcarrier in the frequency domain.

[0538] As an example, any subcarrier occupied by the second PDCCH in the frequency domain belongs to the first BWP (Bandwidth Part).

[0539] As an example, the first information block is used to configure the first BWP.

[0540] As an example, information blocks other than the first information block are used to configure the first BWP.

[0541] As an example, the first BWP is an active BWP.

[0542] As an example, the first BWP is the default BWP.

[0543] As an example, the first BWP is the initial BWP.

[0544] As an example, both the first threshold and the second threshold are predefined or are signaling configurations.

[0545] As an example, both the first threshold and the second threshold are related to the capabilities of the first node device.

[0546] As an example, the capability reporting of the first node device is used to explicitly or implicitly indicate the first threshold and the second threshold.

[0547] As an example, both the first threshold and the second threshold are related to the subcarrier spacing of the first BWP.

[0548] As an example, both the first threshold and the second threshold are related to the number of serving cells configured for the first node device.

[0549] As an example, both the first threshold and the second threshold are related to the number of time-domain symbols included in the first time window.

[0550] As an example, the number of PDCCH monitoring operations performed by the receiver of the target control signaling within the first time window and on the first BWP is not greater than the first threshold, and the number of non-overlapped CCEs occupied by the PDCCH candidates monitored by the receiver of the target control signaling within the first time window and on the first BWP is not greater than the second threshold.

[0551] As an example, the receiver of the target control signaling expects that the number of PDCCH monitoring operations performed on the first time window and the first BWP will not exceed the first threshold, and the number of non-overlapped CCEs occupied by the PDCCH candidates monitored on the first time window and the first BWP will not exceed the second threshold.

[0552] As an example, the receiver of the target control signaling does not expect the number of PDCCH monitoring operations performed within the first time window and on the first BWP to be greater than the first threshold, and the receiver of the target control signaling does not expect the number of non-overlapped CCEs occupied by the PDCCH candidates monitored within the first time window and on the first BWP to be greater than the second threshold.

[0553] As an example, the number of times the receiver of the target control signaling performs PDCCH monitoring for a serving cell within the first time window and on the first BWP does not exceed the first threshold, and the number of non-overlapping CCEs occupied by the PDCCH candidates monitored by the receiver of the target control signaling for a serving cell within the first time window and on the first BWP does not exceed the second threshold.
