Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for transmitting wireless signals in wireless communication systems supporting cellular networks. Background Technology

[0002] In traditional wireless communication, terminals supporting carrier aggregation technology can transmit and receive on multiple cells. Carrier aggregation technology can enable terminals to obtain greater service bandwidth and higher transmission rates, but its utilization efficiency of fragmented spectrum resources is not high. Supporting the configuration of multiple carriers in the same cell can not only obtain greater service bandwidth and higher transmission rates, but also effectively improve the utilization efficiency of fragmented spectrum resources and reduce base station energy consumption.

[0003] Resource allocation mechanism is an important aspect of mobile communication system design, and a good resource allocation mechanism can effectively improve system efficiency. Summary of the Invention

[0004] For scenarios where a single cell comprises multiple frequency blocks (different frequency blocks on different carriers), how to enhance time-domain resource allocation is a problem worthy of research. To address this problem, this application discloses a solution. Where there is no conflict, the embodiments and features in the first node of this application can be applied to the second node. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0005] Where necessary, the interpretation of terms used in this application may be referenced to the descriptions in the TS38 series of specification protocols of 3GPP (3rd Generation Partner Project).

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

[0007] Sending a first signal, or receiving a first signal; the time-domain resource allocation of the first signal depends on one of a first time-domain resource allocation table and a second time-domain resource allocation table; the first time-domain resource allocation table includes multiple time-domain resource allocation items, and the second time-domain resource allocation table includes multiple time-domain resource allocation items;

[0008] The time-domain resource allocation of the first signal depends on either the first time-domain resource allocation table or the second time-domain resource allocation table, depending on the frequency block used for the transmission of the first signal; when the transmission of the first signal is within the first frequency block, the time-domain resource allocation of the first signal depends on the first time-domain resource allocation table; when the transmission of the first signal spans at least the first frequency block and the second frequency block, the time-domain resource allocation of the first signal depends on the second time-domain resource allocation table.

[0009] The first frequency block and the second frequency block belong to the same cell, and the first frequency block and the second frequency block are on different carriers.

[0010] As an example, the problem this application aims to solve includes: how to optimize the time-domain resource allocation of signals by comprehensively considering different frequency domain allocation situations.

[0011] As an example, in the above method, at least for the two cases where the first frequency block is used alone to transmit the first signal, and where both the first frequency block and the second frequency block are used to transmit the first signal, the time-domain resource allocation table on which the time-domain resource allocation of the first signal depends can be different; such a feature provides the possibility of realizing more flexible time-domain resource allocation, which is beneficial to improving resource allocation efficiency.

[0012] As an example, the above method takes into account both single-carrier transmission and cross-carrier transmission, and has good versatility.

[0013] As an example, in the above method, when the transmission of the first signal spans at least the first frequency block and the second frequency block, the time-domain resource allocation of the first signal does not need to rely on multiple time-domain resource allocation tables; this feature simplifies system design and helps reduce equipment costs.

[0014] As one example, the first node is a user equipment.

[0015] As one example, the first node is a terminal.

[0016] According to one aspect of this application, the above method is characterized in that,

[0017] When the transmission of the first signal is within the second frequency block, the time-domain resource allocation of the first signal depends on the second time-domain resource allocation table.

[0018] According to one aspect of this application, the above method is characterized in that,

[0019] The first frequency block set includes more than two frequency blocks. All frequency blocks in the first frequency block set belong to the same cell. Different frequency blocks in the first frequency block set are on different carriers. Both the first frequency block and the second frequency block belong to the first frequency block set.

[0020] When the transmission of the first signal is within a frequency block other than the second frequency block in the first frequency block set, or when the transmission of the first signal spans at least two frequency blocks in the first frequency block set excluding the second frequency block, the time-domain resource allocation of the first signal depends on the first time-domain resource allocation table.

[0021] When the transmission of the first signal spans at least two frequency blocks in the first frequency block set, including the second frequency block, the time-domain resource allocation of the first signal depends on the second time-domain resource allocation table.

[0022] As an example, the above method is specifically designed for cases where the same cell includes three or more frequency blocks, which helps to avoid complex system design while ensuring flexibility.

[0023] According to one aspect of this application, the above method is characterized by comprising:

[0028] As an example, the above method provides the possibility of indicating the contents of different time-domain resource allocation tables under different frequency domain scheduling for the same domain, which is beneficial to improving the utilization efficiency of bits in the first signaling.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0082] Example 1

[0083] Example 1 illustrates a flowchart of communication of a first node according to an embodiment of this application, as shown in the attached diagram. Figure 1 As shown.

[0084] The first node 100 sends a first signal or receives a first signal in step 101.

[0085] In Example 1, the time-domain resource allocation of the first signal depends on one of a first time-domain resource allocation table and a second time-domain resource allocation table; the first time-domain resource allocation table includes multiple time-domain resource allocation entries, and the second time-domain resource allocation table includes multiple time-domain resource allocation entries; whether the time-domain resource allocation of the first signal depends on the first time-domain resource allocation table or the second time-domain resource allocation table is related to the frequency block used for the transmission of the first signal; when the transmission of the first signal is within a first frequency block, the time-domain resource allocation of the first signal depends on the first time-domain resource allocation table; when the transmission of the first signal spans at least the first frequency block and the second frequency block, the time-domain resource allocation of the first signal depends on the second time-domain resource allocation table; wherein, the first frequency block and the second frequency block belong to the same cell, and the first frequency block and the second frequency block are on different carriers.

[0086] As an example, the first signal is transmitted over a physical channel.

[0087] As one embodiment, the first node sends the first signal, which is transmitted over a physical uplink channel.

[0088] As an example, the first node sends the first signal, which is PUSCH (Physical Uplink Shared Channel).

[0089] As an example, the first node receives the first signal, which is transmitted over a physical downlink channel.

[0090] As one embodiment, the first node receives the first signal, which is transmitted on a PDSCH (Physical Downlink Shared Channel).

[0094] As one embodiment, the first signal includes the output of the encoded bits of the information to be transmitted after at least scrambling, modulation, layer mapping, multi-antenna precoding, resource mapping, and physical antenna mapping.

[0095] As an example, receiving (or sending) a physical channel is a common expression in the art, meaning receiving (or sending) a signal on this physical channel; accordingly, in order to be consistent with the common expression in the art, the first signal in this application can also be replaced with the first physical channel (wherein, the first physical channel is used to transmit the first signal).

[0096] As one embodiment, the time-domain resource allocation of the first signal includes time-domain resources allocated for transmitting the first signal.

[0097] As an example, the time-domain resource allocation for the first signal is the time-domain resource allocated to the physical channel used to transmit the first signal.

[0098] As an example, the time-domain resource allocation of the first signal includes at least one symbol.

[0099] As an example, a symbol in this application is a symbol defined in the time domain.

[0100] As an example, a symbol in this application is a basic unit defined in a time-domain structure.

[0101] As an example, a symbol in this application is a symbol in a slot.

[0102] As an example, one of the symbols in this application is the OFDM (Orthogonal Frequency Division Multiplex) symbol.

[0103] As an example, a time-domain resource allocation item in the first time-domain resource allocation table is mapped to a time-domain resource allocation.

[0104] As an example, a time-domain resource allocation item in the second time-domain resource allocation table is mapped to a time-domain resource allocation.

[0105] As an example, the first time-domain resource allocation table is configured, and the second time-domain resource allocation table is configured; a time-domain resource allocation item in the first time-domain resource allocation table is mapped to a time-domain resource allocation (including at least time slot offset and symbol allocation within the time slot), and a time-domain resource allocation item in the second time-domain resource allocation table is mapped to a time-domain resource allocation (including at least time slot offset and symbol allocation within the time slot).

[0106] As an example, both the first time-domain resource allocation table and the second time-domain resource allocation table are configured by higher-layer signaling.

[0107] As one embodiment, the first time-domain resource allocation table is configured by RRC signaling, and the second time-domain resource allocation table is configured by RRC signaling.

[0108] As an example, the configuration signaling name of the first time domain resource allocation table includes TimeDomainResourceAllocationList.

[0109] As an example, the configuration signaling name of the second time domain resource allocation table includes TimeDomainResourceAllocationList.

[0110] As an example, the first time-domain resource allocation table and the second time-domain resource allocation table are configured separately.

[0111] As one embodiment, the time-domain resource allocation of the first signal depends on a time-domain resource allocation table, including:

[0112] Each candidate for the time-domain resource allocation of the first signal follows the indication of a time-domain resource allocation entry in the time-domain resource allocation table.

[0113] As one embodiment, the time-domain resource allocation of the first signal depends on a time-domain resource allocation table, including:

[0114] The time-domain resource allocation of the first signal is determined by the MAC CE (MAC control element, MAC layer control unit) from the time-domain resource allocation items indicated in the target time-domain resource allocation item set. The target time-domain resource allocation item set is composed of the union of all time-domain resource allocation items in the first time-domain resource allocation table and all time-domain resource allocation items in the given time-domain resource allocation table. The given time-domain resource allocation table is configured by RRC signaling, and the configuration of the given time-domain resource allocation table is independent of the configuration of the first time-domain resource allocation table and the configuration of the second time-domain resource allocation table.

[0115] As one embodiment, the transmission of the first signal is within the first frequency block, or the transmission of the first signal is within the second frequency block, or the transmission of the first signal spans both the first and second frequency blocks.

[0116] As an example, the transmission of the first signal is within one frequency block, and the transmission of the first signal does not span multiple frequency blocks.

[0117] As an example, when all the frequency domain resources allocated to the first signal are frequency domain resources in a frequency block, the transmission of the first signal is within that frequency block.

[0118] As an example, when all the frequency domain resources allocated to the physical channel used to transmit the first signal are frequency domain resources in a single frequency block, the transmission of the first signal is within that frequency block.

[0119] As an example, when each of the plurality of frequency blocks includes a portion of the frequency domain resources allocated to the first signal (wherein all the frequency domain resources allocated to the first signal are a subset of all the frequency domain resources included in the plurality of frequency blocks), the transmission of the first signal spans the plurality of frequency blocks.

[0120] As an example, when each of the plurality of frequency blocks is allocated a portion of the frequency domain resources of the physical channel used to transmit the first signal (wherein all the frequency domain resources allocated to the physical channel used to transmit the first signal are a subset of all the frequency domain resources included in the plurality of frequency blocks), the transmission of the first signal spans the plurality of frequency blocks.

[0121] As one embodiment, the transmission of the first signal spans at least the first frequency block and the second frequency block, comprising: the transmission of the first signal spans multiple frequency blocks, the multiple frequency blocks including at least the first frequency block and the second frequency block.

[0122] As one embodiment, the transmission of the first signal is within a frequency block, which is a frequency block used for the transmission of the first signal; or, the transmission of the first signal spans multiple frequency blocks, all of which are frequency blocks used for the transmission of the first signal.

[0123] As an example, when the transmission of the first signal is within one frequency block, the frequency block used for the transmission of the first signal is that frequency block; when the transmission of the first signal spans multiple frequency blocks, the frequency block used for the transmission of the first signal is the multiple frequency blocks.

[0124] As one embodiment, a frequency block for the transmission of the first signal is a frequency block that includes at least a portion of the frequency domain resources allocated to the first signal.

[0125] As an example, a frequency block for the transmission of the first signal is a frequency block that includes at least a portion of the frequency domain resources allocated to the physical channel for transmitting the first signal.

[0126] As an example, a frequency block is configured.

[0127] As an example, a frequency block comprises contiguous frequency domain resources.

[0128] As an example, a frequency block includes at least a portion of the frequency band on a carrier.

[0129] As an example, a frequency block can be a carrier, or a portion of a frequency band on a carrier (in both cases, the frequency block is considered to be on the carrier).

[0130] As an example, a frequency block includes multiple RBs (Resource Blocks).

[0131] As an example, the carrier in which a frequency block is located is a radio frequency (RF) carrier.

[0132] As an example, the carrier of a frequency block is a radio frequency channel.

[0133] As an example, the carrier of a frequency block is a radio frequency channel after channelization.

[0134] As an example, the carrier of a frequency block is a channel with a certain radio frequency channel bandwidth.

[0135] As an example, the carrier in which a frequency block is located is a CC (component carrier).

[0136] As an example, a cell is a serving cell.

[0137] As an example, a cell includes a frequency block, which belongs to the cell.

[0138] As an example, a frequency block included in a cell is a frequency block that is configured for that cell.

[0139] As an example, a frequency block included in a cell is a frequency block allocated to a carrier of that cell.

[0140] As an example, the configuration information of a cell includes the configuration information of each frequency block included in the cell.

[0141] As an example, multiple carriers can be configured for a single cell.

[0142] As an example, the same cell in this application includes a plurality of frequency blocks, which are respectively on a plurality of carriers (wherein, the plurality of frequency blocks correspond one-to-one with the plurality of carriers, the plurality of frequency blocks include at least the first frequency block and the second frequency block, and the plurality of carriers are all configured for the same cell).

[0143] As an example, any two of the several carriers are different carriers.

[0144] As an example, among the plurality of carriers, the index of the carrier in which the first frequency block is located is not the smallest, while the index of the carrier in which the second frequency block is located is the smallest.

[0145] As an example, among the plurality of carriers, the index of the carrier in which the first frequency block is located is not the largest, while the index of the carrier in which the second frequency block is located is the largest.

[0146] As one embodiment, the plurality of carriers includes a primary carrier or an anchor carrier.

[0147] As an example, the carrier carrying SIB1 among the plurality of carriers is the main carrier (or anchor carrier).

[0148] As an example, the carrier among the plurality of carriers that has CORESET#0 (control resource set#0) or has an initial BWP (bandwidth part) is the main carrier (or anchor carrier).

[0149] As one example, the carrier in which the second frequency block is located is the main carrier (or anchor carrier).

[0150] As an example, the carriers all belong to the same frequency range (FR).

[0151] As an example, the plurality of carriers all belong to frequency range 1 (FR1).

[0152] As an example, limiting the carriers to the same frequency range (at least in the initial version) reduces implementation complexity while effectively utilizing the existing main fragmented spectrum.

[0153] As one example, among the plurality of carriers, there are two carriers belonging to different frequency ranges.

[0154] As an example, the plurality of carriers employ the same mathematical structure.

[0155] As one embodiment, the plurality of carriers employ the same subcarrier spacing.

[0156] As an example, restricting the plurality of carriers to use the same subcarrier spacing simplifies the scheduling design.

[0157] As one example, among the plurality of carriers, there are two carriers that use different subcarrier spacings.

[0172] Example 3

[0173] 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 used by user equipment and network-side equipment is illustrated in 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 user equipment and network-side equipment 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 network-side equipment. 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-area mobility between network-side equipment and user equipment. 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 user equipment. 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 layers using RRC signaling between network-side equipment and user equipment. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for user equipment and network-side equipment 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 user equipment 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.).

[0180] Example 4

[0181] Example 4 illustrates a hardware module schematic diagram of a communication node according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in the access network.

[0182] The first 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.

[0183] The second 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.

[0184] In the transmission from the second communication device 410 to the first communication device 450, at the second 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 second communication device 410 to the first 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 first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first 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 channel coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, 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.

[0185] In the transmission from the second communication device 410 to the first communication device 450, at the first 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 first 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 deinterleaves and decodes the soft decisions to recover the upper-layer data and control signals transmitted by the second 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 second communication device 410 to the second node 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.

[0186] In the transmission from the first communication device 450 to the second communication device 410, at the first 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 second communication device 410 described in the transmission from the second communication device 410 to the first 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 second communication device 410. Transmit processor 468 performs channel coding, interleaving, and modulation mapping. Multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0187] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.
