Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to multi-carrier transmission schemes and apparatus 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-carrier technology (including carrier aggregation and dual connectivity) is an important component. To adapt to diverse application scenarios and meet different needs, 3GPP has been evolving multi-carrier technology since Release 15. Summary of the Invention

[0004] In multi-carrier communication processes, such as carrier aggregation (CA), cross-carrier scheduling is supported. In networks supported by existing standards, such as 5G NR (New Radio) versions R17 and earlier, for multiple scheduled carriers, scheduling is only supported on their respective corresponding carriers or their corresponding PDCCH (Physical Downlink Control Channel), and scheduling through the same PDCCH on the same carrier is not supported.

[0005] This application discloses a solution to the problem of simultaneously scheduling multiple carriers using the same PDCCH in a multi-carrier NR system. It should be noted that the description in this application uses PDCCH scheduling in a multi-carrier system as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (such as other scenarios with higher requirements for control channel capacity, including but not limited to capacity enhancement systems, systems using higher frequencies, coverage enhancement systems, unlicensed frequency domain communication, IoT (Internet of Things), URLLC (Ultra-Reliable Low-Latency Communication) networks, vehicle-to-everything (V2X) networks, etc.), and can achieve similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to multi-carrier 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 explanations of terms, nouns, functions, and variables in this application (unless otherwise specified) can refer to the definitions in the 3GPP specification protocols TS36, TS38, and TS37 series.

[0008] At least one PDCCH candidate is monitored in a first time window, which includes at least one time-domain consecutive multicarrier symbol;

[0009] In this process, the subcarrier spacing occupied by at least one PDCCH candidate monitored in the first time window in the frequency domain is equal to the first subcarrier spacing, which is used to determine the time length of a multi-carrier symbol included in the first time window; the number of PDCCH candidates using the first subcarrier spacing monitored in the first time window is not greater than a first threshold, and the number of non-overlapping CCEs using the first subcarrier spacing monitored in the first time window is not greater than a second threshold, where the first threshold is a positive integer and the second threshold is a positive integer; at least one PDCCH candidate monitored in the first time window is used to schedule at least one serving cell included in the first cell set, which includes at least one cell subset, and any cell subset included in the first cell set includes at least one serving cell; all serving cells included in a cell subset of the first cell set can be scheduled by the same PDCCH candidate; both the first threshold and the second threshold are related to a feature ratio value, and the number of serving cells included in the at least one cell subset of the first cell set is used to determine the feature ratio value, which is not less than 0.

[0010] As an example, the number of serving cells included in at least one subset of cells in the first cell set is used to determine the characteristic ratio value, thereby reducing the probability of scheduling congestion.

[0011] According to one aspect of this application, the above method is characterized in that the feature cell subset is a subset of cells included in the first cell set, the feature cell subset including multiple serving cells; the number of serving cells included in the feature cell subset is not equal to the number of serving cells included in the feature cell subset.

[0017] As an example, associating at least one of the number of bits of at least one field included in the DCI format or the number of fields included with the number of serving cells included in the scheduled subset of cells further improves configuration flexibility and reduces standard complexity and signaling overhead.

[0023] As an example, only one of the two PDCCH candidates, the first PDCCH candidate or the second PDCCH candidate, is counted in the monitoring count. This avoids exceeding the user equipment's capacity for PDCCH candidate monitoring or increasing the complexity of PDCCH reception, while fully utilizing the monitoring capability of PDCCH candidates, further reducing the probability of PDCCH blocking and improving scheduling flexibility.

[0141] As an example, when the first time window includes more than one multicarrier symbol, the time lengths of any two multicarrier symbols included in the first time window are equal.

[0142] As an example, when the first time window includes more than one multi-carrier symbol, the time lengths of the two multi-carrier symbols included in the first time window are not equal.

[0143] As an example, the sentence "The first subcarrier interval is used to determine the time length of a multi-carrier symbol included in the first time window" has the following meaning: The first subcarrier interval is used by the first node device in this application to determine the time length of a multi-carrier symbol included in the first time window.

[0301] Example 3

[0302] 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.).

[0308] Example 4

[0309] 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.

[0310] 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.

[0311] 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.

[0312] In the DL (Downlink) process, higher-layer packets, such as the higher-layer information included in the first and second information blocks in this application, are provided to the controller / processor 440. The controller / processor 440 implements functions at Layer 2 and above. In the DL process, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logic and transport channels, and radio resource allocation to 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; for example, the higher-layer information included in the first and second information blocks in this application is generated in the controller / processor 440. The transmit processor 415 implements various signal processing functions for Layer 1 (i.e., physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation; for example, the generation of the physical layer signals of the first and second information blocks and the physical layer signals corresponding to the PDCCH candidates in this application is completed in the transmit processor 415. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multicarrier subcarrier and / or multicarrier symbol. These are then transmitted by the transmit processor 415 via the transmitter 416 to the antenna 420 as radio frequency (RF) signals. At the receiver, each receiver 456 receives the RF signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the RF carrier and provides the baseband information to the receive processor 452. The receive processor 452 implements various signal reception processing functions at Layer 1. These functions include monitoring the physical layer signals and PDCCH candidates of the first and second information blocks in this application, demodulating the multicarrier symbols in the multicarrier symbol stream based on 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, and then providing the data and control signals 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 second information block 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 a computer-readable medium.

[0313] In uplink (UL) transmission, similar to downlink transmission, the higher-layer information, including the higher-layer information contained in the third information block of this application, is generated by the controller / processor 490 and then processed by the transmitter processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., physical layer). This includes the generation of the physical layer signal carrying the third information block, which is completed by the transmitter processor 455 and then transmitted by the transmitter processor 455 via the transmitter 456 to the antenna 460 as a radio frequency signal. The receiver 416 receives the radio frequency signal through its corresponding antenna 420. Each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receiver processor 412. The receiver processor 412 implements various signal reception processing functions for the L1 layer (i.e., physical layer), including receiving and processing the physical layer signal carrying the third information block, and then providing data and / or control signals to the controller / processor 440. The controller / processor 440 implements L2 layer functions, including the interpretation of the higher-layer information, including the interpretation of the higher-layer information carried by the third information block. The controller / processor may be associated with a cache 430 that stores program code and data. The cache 430 may be computer-readable media.

[0449] Example 8

[0450] Example 8 illustrates a schematic diagram of a scheduling instruction value according to an embodiment of this application, as shown in the attached diagram. Figure 8 As shown. In the appendix Figure 8 In the diagram, each arc-shaped apex region represents a serving cell in the first cell set, each dot-filled arc-shaped apex region represents a serving cell in the feature cell subset, the dashed lines with arrows represent the scheduling and being-scheduled relationships between serving cells, and the identifier SI (scheduling indicator) in each serving cell represents the corresponding scheduling indicator value.

[0451] In embodiment 8, each serving cell included in the first cell set of this application corresponds to a scheduling indication value, and the serving cells included in the first cell set that correspond to equal scheduling indication values ​​and have the same scheduling cell constitute a cell subset in the first cell set; at least one of the number of bits of at least one field included in a DCI format or the number of fields included is related to the number of serving cells included in the cell subset of the first cell set that is scheduled.

[0452] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is equal to a CIF (carrier indicator field) value.

[0453] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is equal to the CIF value of the corresponding serving cell.

[0454] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is equal to the indication value independent of CIF.

[0455] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is equal to the indication value other than the CIF of the corresponding serving cell.

[0456] As an example, the scheduling indication value corresponding to one serving cell included in the first cell set is equal to the value of the indication other than the CIF of the corresponding serving cell, and the scheduling indication value corresponding to another serving cell included in the first cell set is equal to the value of the CIF of the corresponding serving cell.

[0457] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is independent of the value configured by the CIF of the corresponding serving cell.

[0458] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is equal to the value configured in the field outside the field of the CIF value of the corresponding serving cell.

[0459] As an example, the scheduling indication value corresponding to at least one or any one serving cell in the first cell set is configured independently of the CIF value.

[0460] As an example, in the first set of cells, there exists a serving cell whose scheduling indication value is equal to a default value or a predefined value.

[0461] As an example, there exists a serving cell in the first cell set whose scheduling indication value is equal to 0.

[0462] As an example, in the first cell set, at least one serving cell has a scheduling indication value that is configured by signaling.

[0463] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is greater than 0.

[0464] As an example, the first cell set includes two serving cells whose respective scheduling indication values ​​are not equal.

[0465] As an example, the first cell set includes two serving cells whose respective scheduling indication values ​​are equal.

[0466] As an example, the scheduling indication values ​​corresponding to any two serving cells included in the first cell set are not equal.

[0467] As an example, the first information block is used to explicitly or implicitly indicate at least one scheduling indication value corresponding to at least one serving cell included in the first cell set.

[0468] As an example, information blocks other than the first information block are used to explicitly or implicitly indicate at least one scheduling indication value corresponding to at least one serving cell included in the first cell set.

[0469] As an example, at least one scheduling indication value corresponding to at least one serving cell included in the first cell set is explicitly or implicitly configured by the IE that configures the CIF value of the corresponding serving cell.

[0470] As an example, at least one scheduling indication value corresponding to at least one serving cell included in the first cell set is explicitly or implicitly configured by an IE other than the IE that configures the CIF value of the corresponding serving cell.

[0471] As an example, at least one scheduling indication value corresponding to at least one serving cell included in the first cell set is explicitly or implicitly configured by the IE of the corresponding serving cell.

[0472] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is a positive integer not greater than 7.

[0473] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is a non-negative integer not greater than 7.

[0474] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is no greater than 31.

[0475] As an example, the scheduling indication value corresponding to a serving cell included in the first cell set is greater than 7.

[0476] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is greater than 7.

[0477] As an example, the scheduling indication value corresponding to a serving cell included in the first cell set is greater than 31.

[0478] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is greater than 31.

[0479] As an example, the range of values ​​for the scheduling indication value corresponding to any serving cell included in the first cell set is predefined.

[0480] As an example, the range of values ​​for the scheduling indication value corresponding to any serving cell included in the first cell set is configurable.

[0481] As an example, the range of values ​​for the scheduling indication value corresponding to any serving cell included in the first cell set is related to the protocol release.

[0482] As an example, the correspondence between the serving cells included in the first cell set and their corresponding scheduling indication values ​​is configurable or predefined.

[0483] As an example, the scheduling indication value corresponding to a serving cell included in the first cell set is an indication value applicable to that serving cell.

[0484] As an example, the scheduling indication value corresponding to a serving cell included in the first cell set is an indication value for granting or assigning an application applicable to that serving cell.

[0485] As an example, the scheduling indication value corresponding to a serving cell included in the first cell set is an indication value for determining the distribution or position of the PDCCH candidates for scheduling this serving cell in the search space set to which they belong.

[0486] As an example, the scheduling indication value corresponding to a serving cell included in the first cell set is an indication value configured for that serving cell.

[0487] As an example, the scheduling indication value corresponding to a serving cell included in the first cell set is an indication value associated with that serving cell.

[0488] As an example, the scheduling indication value corresponding to any serving cell included in the first cell set is used in the scheduling cell of that serving cell.

[0489] As an example, the range of values ​​for the scheduling indication value corresponding to a serving cell included in the first cell set is used to determine whether the corresponding serving cell is scheduled together with other serving cells.

[0490] As an example, the statements in the claims "the serving cells included in the first cell set that have corresponding equal scheduling indication values ​​and the same scheduling cell constitute a subset of cells in the first cell set" and "any two serving cells included in any subset of cells in the first cell set that have corresponding equal scheduling indication values ​​and the same scheduling cell" are equivalent or can be used interchangeably.

[0491] As an example, the statements in the claims "serving cells with corresponding equal scheduling indication values ​​and the same scheduling cell included in the first cell set constitute a subset of cells in the first cell set" and "any two serving cells included in a given subset of cells in the first cell set have corresponding equal scheduling indication values ​​and the same scheduling cell" are equivalent or can be used interchangeably.

[0492] As an example, the claims state that "serving cells with corresponding equal scheduling indication values ​​and the same scheduling cells included in the first cell set constitute a subset of cells in the first cell set" and "any subset of cells in the first cell set that includes multiple serving cells is composed of serving cells with corresponding equal scheduling indication values ​​and the same scheduling cells".

[0493] As an example, the scheduling cell of a serving cell is the serving cell that carries scheduling information of channels or signals on the serving cell.

[0494] As an example, the scheduling cell of a serving cell is the serving cell to which the grant or assignment of this serving cell belongs.

[0495] As an example, the scheduling cell of a serving cell is the serving cell to which the PDCCH that schedules the channels or signals on that serving cell belongs.

[0496] As an example, when self-scheduling is used, the scheduling cell of a serving cell is the serving cell itself; when cross-carrier scheduling is used, the scheduling cell of a serving cell is a serving cell other than the serving cell itself.

[0497] As an example, the statement in the claim that "at least one of the number of bits of at least one field included in a DCI format or the number of fields included is related to the number of serving cells included in the cell subset of the first cell set scheduled" includes the following meaning: the number of bits of at least one field included in a DCI format is related to the number of serving cells included in the cell subset of the first cell set scheduled.
