Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus for control channels 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) technology, extending NR to higher frequency spectrum bands is an important issue. To adapt to more diverse application scenarios and meet higher demands, the 3GPP RAN#86 plenary meeting approved extending NR systems to the spectrum between 52.6 GHz and 71 GHz. To support greater bandwidth and combat more severe phase noise, larger subcarrier spacing, such as 480 kHz and 960 kHz, will be supported at 52.6 GHz and 71 GHz. In this case, compared to subcarrier spacing of 120 kHz or less, the length of OFDM (Orthogonal Frequency Divided Multiplexing) symbols will become shorter, and correspondingly, the slot spacing will also become shorter.

[0004] In an NR system, a UE (User Equipment) is configured with one or more UE-specific Search Space Sets (USS sets) and Common Search Space Sets (CSS sets). Each USS set or CSS set includes a set of Physical Downlink Control Channel (PDCCH) candidates. The UE must perform blind decoding (BD) on the USS set or CSS set to determine if a PDCCH is available for transmission to it. Summary of the Invention

[0005] The inventors discovered through research that using a larger subcarrier spacing would make the OFDM symbol length and time slot length shorter, requiring the UE to perform PDCCH blind detection more quickly and frequently, resulting in excessive UE implementation complexity and energy consumption, which is not conducive to controlling UE cost and energy consumption.

[0006] To address the aforementioned problems, this application discloses a solution. It should be noted that, although the description in this application uses an air interface transmission scenario between a cellular network gNB (next generation Node B) and a UE (User Equipment) as an example, this application is also applicable to other communication scenarios (such as wireless LAN scenarios, secondary link transmission scenarios between user equipments, etc.) and achieves similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to cellular networks, wireless LANs, secondary link transmission scenarios, etc.) also helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the embodiments of the first node of this application can be applied to the second node, and vice versa. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0007] As an example, the interpretation of the terminology in this application is based on the definitions in the 3GPP specification protocol TS36 series.

[0008] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0009] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS37 series.

[0010] As an example, the interpretation of terms in this application is based on the definitions in the IEEE (Institute of Electrical and Electronics Engineers) specification protocols.

[0011] This application discloses a method for a first node in wireless communication, characterized by comprising:

[0012] The system receives a first information block and a second information block. The first information block is used to indicate a first set of control channel candidates, and the second information block is used to indicate a second set of control channel candidates. The first set of control channel candidates includes at least one control channel candidate. The second set of control channel candidates includes at least one control channel candidate. The time-frequency resources occupied by any one of the control channel candidates included in the first set of control channel candidates belong to a first set of time-frequency resources, and the time-frequency resources occupied by any one of the control channel candidates included in the second set of control channel candidates belong to a second set of time-frequency resources.

[0013] Monitor Q1 control channels as candidates, where Q1 is an integer greater than 1;

[0014] Wherein, the time-frequency resources included in the first time-frequency resource set belong to the first time window in the time domain; the time interval length between the first time-frequency resource set and the second time-frequency resource set in the time domain is equal to the first time length; the first time length is less than the time length of the first time window; and the time length of the first time window is greater than the time length of a time slot; any one of the Q1 control channel candidates belongs to either the first control channel candidate set or the second control channel candidate set; Q1 is not greater than the maximum monitoring number, and the maximum monitoring number is a positive integer; the first time length and the time length of the first time window are used together to determine the maximum monitoring number.

[0015] As an example, the feature of the above method is that the maximum number of monitoring is the maximum number of PDCCH blind detections supported by the UE within the first time window, and the first time window includes the time length of a positive integer number of time slots.

[0016] As an example, the advantage of the above method is that the maximum number of monitoring is defined within a first time window, and the first time window is longer than the time length of a time slot; the UE can perform blind detection of the PDCCH within the first time window, so compared with PDCCH monitoring based on a time slot or less, the UE can support more blind detection times under the same signal processing capability.

[0017] As an example, the characteristic of the above method is that the first time-frequency resource set is located in the first time slot of the first time window.

[0018] As an example, the feature of the above method is that the first control channel candidate set includes at least one USS set.

[0019] As an example, the characteristic of the above method is that the UE assumes that only one time slot is configured with the USS set within the first time window.

[0020] As an example, the advantages of the above method are: the first time window includes multiple time slots, and the UE only needs to monitor the USS set in one of the time slots, which reduces the complexity of the UE and is conducive to UE energy saving.

[0021] As an example, the feature of the above method is that the second time-frequency resource set is located in one of the time slots after the first time slot in the first time window.

[0022] As an example, the feature of the above method is that the second control channel candidate set includes at least one CSS set.

[0023] As an example, the advantages of the above method are: the first time window includes multiple time slots, and the CSS set can be configured without restriction in time slots after the first time slot within the first time window; since the CSS set includes control signaling for multicast or broadcast, the above method is beneficial to improve the flexibility of CSS set configuration, so that different UEs can monitor the CSS set in the same PDCCH monitoring opportunity.

[0024] As an example, the advantage of the above method is that the first time-frequency resource set precedes the second time-frequency resource set in the time domain; therefore, the UE starts monitoring the first control channel candidate set first, and then starts monitoring the second control channel candidate set. Due to the sequential relationship of signal processing, when the UE starts monitoring the second control channel candidate set, some of the computing resources (e.g., storage space, processing processes, etc.) used for monitoring the first control channel candidate set have already been released. These released computing resources can be reused for monitoring the second control channel candidate set. When the first time length is large, more computing resources will be released, so the maximum number of monitoring operations that the UE can support within the first time window can also be greater; conversely, when the first time length is small, the maximum number of monitoring operations that the UE can support within the first time window will also be smaller. By adopting the above method, computing resources can be utilized more fully, enabling the UE to support a greater number of blind detections of PDCCH candidates.

[0025] According to one aspect of this application, the method is characterized in that the maximum number of monitoring components includes a first monitoring quantity component and a second monitoring quantity component, wherein the first monitoring quantity component is independent of the first time length, and the first time length is used to determine the second monitoring quantity component.

[0026] As an example, the characteristic of the above method is that: the first monitoring quantity component is determined by the UE's maximum PDCCH blind detection capability; the second monitoring quantity component is determined by the blind detection capability that the UE can release and reuse after the first time length. Therefore, the first monitoring component is independent of the first time length, while the second monitoring component is related to the first time length.

[0027] As an example, the feature of the above method is that the PDCCH monitoring capability represented by the first monitoring quantity component can be used for monitoring the first control channel candidate set and the second control channel candidate set.

[0028] As an example, the characteristic of the above method is that the PDCCH monitoring capability represented by the second monitoring quantity component is only used for monitoring the second control channel candidate set, and not for monitoring the first control channel candidate set.

[0029] As an example, the advantage of the above method is that by dividing the maximum number of monitoring components into a first monitoring component and a second monitoring component, the PDCCH monitoring capability can be allocated more accurately to the first control channel candidate set and the second control channel candidate set.

[0030] According to one aspect of this application, the above method is characterized by comprising:

[0031] Send the third information block;

[0032] The third information block is used to determine that the first node has the ability to determine the maximum number of monitoring points based on the first time length and the time length of the first time window.

[0033] According to one aspect of this application, the above method is characterized in that the third information block is used to determine a plurality of monitoring capability candidates supported by the first node, and the second monitoring quantity component is one of the plurality of monitoring capability candidates.

[0034] According to one aspect of this application, the above method is characterized in that, when the number of control channel candidates included in the second control channel candidate set is not greater than the second monitoring quantity component, the number of control channel candidates belonging to the Q1 control channel candidates in the first control channel candidate set is not greater than the first monitoring quantity component.

[0035] According to one aspect of this application, the above method is characterized in that any control channel candidate in the second control channel candidate set belongs to a common search space set.

[0036] According to one aspect of this application, the above method is characterized by comprising:

[0037] Receive the fourth information block;

[0038] The fourth information block indicates a third control channel candidate set, which includes at least one control channel candidate; the time-frequency resources occupied by any one of the control channel candidates in the third control channel candidate set belong to a third time-frequency resource set; the time interval between the first time-frequency resource set and the third time-frequency resource set in the time domain is a second time length, which is not less than the first time length.

[0039] As an example, the characteristic of the above method is that the third control channel candidate set includes the CSS set.

[0040] As an example, the advantage of the above method is that when there are two CSS sets after the first control channel candidate set, both CSS sets are within the first time window, and the two time intervals between the two CSS sets and the first control channel candidate set are different, only the smaller of the two time intervals is used as the basis for determining the maximum number of monitoring, which can simplify the complexity of determining the maximum number of monitoring.

[0041] This application discloses a method for a second node in wireless communication, characterized by comprising:

[0042] A first information block and a second information block are transmitted. The first information block is used to indicate a first control channel candidate set, and the second information block is used to indicate a second control channel candidate set.

[0045] According to one aspect of this application, the method is characterized in that the maximum number of monitoring components includes a first monitoring quantity component and a second monitoring quantity component, wherein the first monitoring quantity component is independent of the first time length, and the first time length is used to determine the second monitoring quantity component.

[0047] Receive the third information block;

[0048] The third information block is used to determine that the sending node of the third information block has the ability to determine the maximum number of monitoring based on the first time length and the time length of the first time window.

[0049] According to one aspect of this application, the above method is characterized in that the third information block is used to determine a plurality of monitoring capability candidates supported by the sending node of the third information block, wherein the second monitoring quantity component is one of the plurality of monitoring capability candidates.

[0050] According to one aspect of this application, the above method is characterized in that, when the number of control channel candidates included in the second control channel candidate set is not greater than the second monitoring quantity component, the number of control channel candidates belonging to the Q1 control channel candidates in the first control channel candidate set is not greater than the first monitoring quantity component.

[0051] According to one aspect of this application, the above method is characterized in that any control channel candidate in the second control channel candidate set belongs to a common search space set.

[0052] According to one aspect of this application, the above method is characterized by comprising:

[0055] This application discloses a first node for wireless communication, characterized in that it comprises:

[0056] A first receiver receives a first information block and a second information block. The first information block is used to indicate a first set of control channel candidates, and the second information block is used to indicate a second set of control channel candidates. The first set of control channel candidates includes at least one control channel candidate. The second set of control channel candidates includes at least one control channel candidate. The time-frequency resources occupied by any one of the control channel candidates included in the first set of control channel candidates belong to a first set of time-frequency resources, and the time-frequency resources occupied by any one of the control channel candidates included in the second set of control channel candidates belong to a second set of time-frequency resources.

[0057] The first receiver monitors Q1 control channel candidates, where Q1 is an integer greater than 1;

[0058] Wherein, the time-frequency resources included in the first time-frequency resource set belong to the first time window in the time domain; the time interval length between the first time-frequency resource set and the second time-frequency resource set in the time domain is equal to the first time length; the first time length is less than the time length of the first time window; and the time length of the first time window is greater than the time length of a time slot; any one of the Q1 control channel candidates belongs to either the first control channel candidate set or the second control channel candidate set; Q1 is not greater than the maximum monitoring number, and the maximum monitoring number is a positive integer; the first time length and the time length of the first time window are used together to determine the maximum monitoring number.

[0059] This application discloses a second node for wireless communication, characterized in that it comprises:

[0060] A second transmitter transmits a first information block and a second information block. The first information block is used to indicate a first set of control channel candidates, and the second information block is used to indicate a second set of control channel candidates. The first set of control channel candidates includes at least one control channel candidate. The second set of control channel candidates includes at least one control channel candidate. The time-frequency resources occupied by any one of the control channel candidates included in the first set of control channel candidates belong to a first set of time-frequency resources, and the time-frequency resources occupied by any one of the control channel candidates included in the second set of control channel candidates belong to a second set of time-frequency resources.

[0061] The second transmitter determines Q1 control channels as candidates, where Q1 is an integer greater than 1;

[0062] Wherein, the time-frequency resources included in the first time-frequency resource set belong to the first time window in the time domain; the time interval length between the first time-frequency resource set and the second time-frequency resource set in the time domain is equal to the first time length; the first time length is less than the time length of the first time window; and the time length of the first time window is greater than the time length of a time slot; any one of the Q1 control channel candidates belongs to either the first control channel candidate set or the second control channel candidate set; Q1 is not greater than the maximum monitoring number, and the maximum monitoring number is a positive integer; the first time length and the time length of the first time window are used together to determine the maximum monitoring number.

[0063] As an example, the method in this application has the following advantages:

[0064] - The blind detection capability of PDCCH can be defined within the time length of multiple time slots. Compared with PDCCH monitoring based on a time slot or an interval of less than a time slot, the UE can support more blind detection times under the same signal processing capability.

[0065] - For time windows containing multiple time slots, the UE only needs to monitor the USS in one time slot, without having to monitor the USS in other time slots, which reduces the complexity of the UE and helps the UE save energy.

[0066] - For time windows containing multiple time slots, CSS collections can be configured in any of the time slots without restriction; this improves the flexibility of CSS collection configuration.

[0067] - While reducing the complexity of blind detection of UE PDCCH, it makes full use of the computing resources that have been released by UE, enabling UE to support a larger number of PDCCH alternative blind detections;

[0068] - Dividing the maximum number of blind PDCCH detections into two components, which respectively reflect the UE's maximum monitoring capability and the ability to reclaim and utilize released computing resources, allows for a more accurate allocation of PDCCH monitoring capabilities to the PDCCH candidate set located in the first time slot of the first time window and the PDCCH candidate set not located in the first time slot of the first time window.

[0069] - When there are multiple CSS sets that are not located in the first time slot of the first time window, the PDCCH candidate set that is closer to the first time slot of the first time window can be used as the basis for determining the maximum number of blind PDCCHs, which can simplify the complexity of determining the maximum number of blind PDCCHs.

The 5G NR or LTE network architecture 200 can 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 Node B (gNB) 203 and other gNBs 204. gNB 203 provides user and control plane protocol termination to UE 201. gNB 203 can connect to other gNBs 204 via an Xn interface (e.g., backhaul). gNB 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 term. gNB 203 provides UE 201 with an access point to 5GC / EPC 210.

[0245] Example 3

[0246] 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 (UE or gNB) and the second node (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 as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second nodes via PHY301. L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node. 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 and first nodes. 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 the first nodes. 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 nodes. 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 nodes 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 streams and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the first node may have several upper layers above 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.).

[0254] Example 4

[0255] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. 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.

[0256] 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.

[0257] 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.

[0258] 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 the transmission from the first communication device 410 to the second communication device 450, 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 retransmitting 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 the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. 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 transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0259] 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 spatial stream destined for the second communication device 450. Symbols on each spatial 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 by the first communication device 410 over the physical channel. 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. 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 transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0260] 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 transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the first communication device 410.
