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 existing NR (New Radio) systems, spectrum resources are statically divided into FDD (Frequency Division Duplex) and TDD (Time Division Duplex) spectrum. For TDD spectrum, both base stations and UEs (User Equipment) operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates the impact of cross-link interference (CLI), but it also leads to decreased resource utilization and increased latency. To address these issues, supporting flexible duplex modes or variable link directions (uplink, downlink, or flexible) on TDD or FDD spectrum has become a possible solution. At the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) 1#103e meeting, research on duplex technology was approved, particularly the proposal of Subband Non-Overlapping Full Duplex (SBFD) mode at the gNB (NR Node B) end. In this mode, the same symbol is used for uplink in some frequency resources and downlink in others, thus improving resource utilization and reducing latency. Summary of the Invention

[0003] In scenarios where symbols are configured as downlink signals indicated by uplink / downlink TDD configuration signaling and are usable for uplink transmission, determining the transmission power of signals on a cell group is a crucial issue. This application discloses a solution to this problem. It should be noted that this application is applicable to various wireless communication scenarios, such as scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, scenarios using more flexible duplex modes, and scenarios supporting only half-duplex mode, achieving similar technical effects. Furthermore, using a unified solution for different scenarios (including but not limited to scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, scenarios using more flexible duplex modes, and scenarios supporting only half-duplex mode) can help reduce hardware complexity and cost, or improve performance. Without conflict, embodiments and features in any node of this application can be applied to any other node. Without conflict, embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0092] As an example, the first cell group and the second cell group are two cell groups under a dual connectivity configuration.

[0093] As an example, the second cell group is different from the first cell group in that the first cell group is an SCG (Secondary cell group), and the second cell group is an MCG (Master cell group).

[0094] As an example, the second cell group is different from the first cell group in that the second cell group is an SCG and the first cell group is an MCG.

[0095] As one embodiment, the first signal includes a wireless signal.

[0096] As an example, the first signal is an uplink signal.

[0097] As an example, the first signal is scheduled by DCI (Downlink control information).

[0098] As an example, the first signal is triggered by DCI.

[0099] As an example, the first signal is semi-statically configured.

[0100] As an example, when the first node transmits the first signal on one cell of the first cell group, the first node transmits the first signal on the first cell group.

[0101] As an example, the frequency domain resources occupied by signals transmitted on a cell group belong to the frequency domain resources allocated to at least one cell included in the cell group.

[0102] As an example, the first signal is PUSCH.

[0115] As an example, combined with the above features, the method disclosed in this application has good compatibility with the 5G NR protocol specifications.

[0116] As an example, the first reference power is configured by RRC signaling.

[0117] As an example, semi-static-mode2 for nrdc-PCmode-FR1 is provided to the first node.

[0118] As an example, semi-static-mode2 for nrdc-PCmode-FR2 is provided to the first node.

[0119] As an example, the first cell group is SCG, the second cell group is MCG, and the second cell group is in FR1 (Frequency range 1).

[0120] As an example, the first cell group is one of SCG and MCG, and the second cell group is the other of SCG and MCG.

[0121] As an example, the total transmit power of the first node in the first cell group and the second cell group is limited, and the upper limit of the total transmit power is configurable.

[0122] As an example, when the total transmission power of the signals to be transmitted by the first node in the first cell group and the second cell group exceeds the upper limit, the first node reduces the transmission power of the signals in the second cell group to ensure that the total transmission power does not exceed the upper limit.

[0123] As an example, the first node is configured with a reference TDD configuration for E-UTRA; when a subframe on the first cell group is an uplink subframe in the reference TDD configuration, the first node does not want to transmit signals in the corresponding time slot on the second cell group.

[0124] As an example, from a time domain perspective, the time domain resources of the first signal are used for the transmission of the first signal.

[0125] As an example, the temporal resource of the first signal is the subframe in which the first signal is located.

[0126] As an example, the time-domain resource of the first signal is: symbols(s) for the first signal.

[0130] As an example, one of the symbols in this application is the SC-FDMA (Single-carrier Frequency-Division Multiple Access) symbol.

[0131] As one example, the first signal overlaps with a time slot of the first cell group.

[0137] When the time-domain resources of the first signal overlap with at least one symbol of the first type belonging to the first type of time-domain resources, the first node uses the first reference power as the maximum transmission power to determine the first power; when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time-domain resources, the first node determines the first power without considering the first reference power.

[0138] As an example, the advantages of the above method include: it helps to optimize spectral efficiency.

[0139] As an example, the statement "whether the first node uses the first reference power as the maximum transmit power to determine whether the time-domain resource of the first power dependent on the first signal overlaps with at least one first-class symbol belonging to the first-class time-domain resource" includes:

[0140] When the time-domain resources of the first signal overlap with at least one symbol of the first type belonging to the first type of time-domain resources, the first node uses the first reference power as the maximum transmission power to determine the first power; when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time-domain resources, the first node determines the first power without considering the first reference power as the maximum transmission power.

[0141] As an example, the advantages of the above method include: it helps to optimize spectral efficiency.

[0142] As an example, if the time-domain resources of the first signal overlap with at least one symbol of the first class belonging to the first class of time-domain resources, then the first node uses the first reference power as the maximum transmission power to determine the first power; otherwise, the first node does not use the first reference power as the maximum transmission power to determine the first power.

[0143] As one embodiment, determining the first power without using the first reference power as the maximum transmission power includes: the first node determining the first power without considering the first reference power.

[0144] As one embodiment, the first node determining the first power without using the first reference power as the maximum transmission power includes: the first node determining the first power without considering the first reference power as the maximum transmission power.

[0145] As an example, if the time-domain resources of the first signal overlap with at least one symbol of the first class belonging to the first class of time-domain resources, the first node uses the first reference power as the maximum transmission power to determine the first power; otherwise, the first node determines the first power without considering the first reference power.

[0151] As an example, when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time-domain resources, the first node does not use the first reference power as the maximum transmission power to determine the first power.

[0152] As an example, when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time-domain resources, the first node determines the first power without considering the first reference power as the maximum transmission power.

[0153] As an example, when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time-domain resources, the first node determines the first power without considering the first reference power.

[0154] As an example, the meaning of "the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time-domain resources" is that the time-domain resources of the first signal do not overlap with any of the first type of symbols belonging to the first type of time-domain resources.

[0155] As an example, the statement that the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time-domain resources means that the condition that the time-domain resources of the first signal overlap with at least one of the first type of symbols belonging to the first type of time-domain resources is not satisfied.

[0156] As an example, the first type of time-domain resource is a symbol(s) that is indicated as downlink by the uplink / downlink TDD configuration signaling and can be used for uplink transmission.

[0160] As an example, whether a symbol indicated as downlink by the uplink / downlink TDD configuration signaling can be used for uplink transmission is configurable.

[0161] As an example, the advantages of the above method include: it helps to improve uplink capacity.

[0162] As an example, the advantages of the above method include: it facilitates support for full-duplex operation.

[0163] As an example, the statement "whether the first node uses the first reference power as the maximum transmit power to determine whether the time-domain resource of the first power dependent on the first signal overlaps with at least one first-class symbol belonging to the first-class time-domain resource" includes:

[0164] When the time-domain resources of the first signal overlap with at least one symbol of the first type belonging to the first type of time-domain resources, the first node uses the first reference power as the maximum transmission power to determine the first power; when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the second type of time-domain resources, the first node determines the first power without considering at least the first reference power; the first type of time-domain resources is a proper subset of the second type of time-domain resources.

[0165] As an example, the statement "whether the first node uses the first reference power as the maximum transmit power to determine whether the time-domain resource of the first power dependent on the first signal overlaps with at least one first-class symbol belonging to the first-class time-domain resource" includes:

[0166] When the time-domain resources of the first signal overlap with at least one symbol of the first type belonging to the first type of time-domain resources, the first node uses the first reference power as the maximum transmission power to determine the first power; when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the second type of time-domain resources, the first node determines the first power without considering at least the first reference power as the maximum transmission power; the first type of time-domain resources is a proper subset of the second type of time-domain resources.

[0167] As an example, when the time-domain resources of the first signal overlap with at least one symbol of the first type belonging to the first type of time-domain resources, the first node uses the first reference power as the maximum transmission power to determine the first power; when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the second type of time-domain resources, the first node does not use at least the first reference power as the maximum transmission power to determine the first power; the first type of time-domain resources is a proper subset of the second type of time-domain resources.

[0168] As an example, when the time-domain resources of the first signal overlap with at least one symbol of the first type belonging to the first type of time-domain resources, the first node uses the first reference power as the maximum transmission power to determine the first power; when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the second type of time-domain resources, the first node determines the first power without considering at least the first reference power; the first type of time-domain resources is a proper subset of the second type of time-domain resources.

[0169] As an example, the advantages of the above method include: it helps to optimize spectral efficiency.

[0170] As an example, when the time-domain resources of the first signal overlap with at least one symbol of the first type belonging to the first type of time-domain resources, the first node uses the first reference power as the maximum transmission power to determine the first power; when the time-domain resources of the first signal do not overlap with the first type of symbols belonging to the second type of time-domain resources, the first node determines the first power without considering at least the first reference power as the maximum transmission power; the first type of time-domain resources is a proper subset of the second type of time-domain resources.

[0171] As an example, the advantages of the above method include: it helps to optimize spectral efficiency.

[0172] As an example, when the time-domain resources of the first signal overlap with at least one symbol of the first class that belongs to the second class of time-domain resources but does not belong to the first time-domain resources, the first node does not use the first reference power as the maximum transmission power to determine the first power.

[0173] As an example, when the time-domain resource of the first signal overlaps with at least one symbol of the first class that belongs to the second class of time-domain resources but does not belong to the first time-domain resource, the first node uses the second reference power as the maximum transmission power to determine the first power.

[0210] Example 3

[0211] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. 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 communication node devices and between the two UEs 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 communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication 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 and first communication 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 communication 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 data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication 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., a remote UE, server, etc.).

[0219] Example 4

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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.

[0224] 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.

[0225] 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. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated 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.

[0226] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the second communication device 450 to the first 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.

[0247] Example 5

[0248] Example 5 illustrates a signal transmission flowchart according to an embodiment of this application, as shown in the attached diagram. Figure 5As shown. In the appendix Figure 5 In this system, the first node U1 and the second node U2 communicate via an air interface.

[0249] The first node U1 receives uplink and downlink TDD configuration signaling in step S511; and sends a first signal on the first cell group in step S512.

[0250] The second node U2 sends uplink and downlink TDD configuration signaling in step S521; and receives the first signal on the first cell group in step S522.

[0251] In Embodiment 5, the first power is the transmission power of the first signal; a first reference power is configured for the first node U1, and the first node U1 determines whether the first power depends on whether the time domain resources of the first signal overlap with at least one first-class symbol belonging to the first-class time domain resources when the time domain resources of the first signal overlap with at least one first-class symbol belonging to the first-class time domain resources; when the time domain resources of the first signal overlap with at least one first-class symbol belonging to the first-class time domain resources, the first node U1 uses the first reference power as the maximum transmission power to determine the first power; the first-class symbol is the symbol of the time slot of the second cell group, the second cell group is different from the first cell group, and the first-class time domain resources include symbols indicated by the uplink / downlink TDD configuration signaling as downlink and usable for uplink transmission.

[0252] As a sub-example of Example 5, when the time domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time domain resources, the first node U1 determines the first power without considering the first reference power.

[0253] As a sub-example of Example 5, when the time domain resources of the first signal do not overlap with the first type of symbols belonging to the first type of time domain resources, the first node U1 determines the first power without considering the first reference power as the maximum transmission power.

[0254] As an example, the first node U1 is the first node in this application.

[0255] As an example, the second node U2 is the second node in this application.

[0256] As an example, the first node U1 is a UE.

[0257] As one example, the second node U2 is a base station.

[0258] As one embodiment, the air interface between the second node U2 and the first node U1 is the Uu interface.

[0262] As one embodiment, the air interface between the second node U2 and the first node U1 includes a wireless interface between the relay device and the user equipment.

[0263] As an example, for the transmitting end of the first signal, whether the first reference power is used as the maximum transmission power is used to determine whether the time domain resources of the first power depending on the first signal overlap with at least one symbol of the first class belonging to the first class of time domain resources.

[0264] As an example, the receiving end of the first signal may make the following assumptions about the behavior of the transmitting end of the first signal: whether the transmitting end of the first signal uses the first reference power as the maximum transmission power to determine whether the time domain resources of the first power dependent on the first signal overlap with at least one of the first type of symbols belonging to the first type of time domain resources.

[0265] As an example, when the time-domain resources of the first signal overlap with at least one symbol of the first class belonging to the first class of time-domain resources, the transmitting end of the first signal uses the first reference power as the maximum transmission power to determine the first power.
