Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, in particular to a method and apparatus for transmitting wireless signals in a wireless communication system supporting a cellular network. Background Art

[0002] In the existing NR (New Radio) system, spectrum resources are statically divided into FDD (Frequency Division Duplex) spectrum and TDD (Time Division Duplex) spectrum. For the TDD spectrum, both the base station and the UE (User Equipment) operate in a half-duplex mode. This half-duplex mode avoids self-interference and can mitigate the impact of Cross Link Interference (CLI), but it also brings problems such as decreased resource utilization and increased latency. To address these problems, it becomes a possible solution to support a flexible duplex mode or variable link directions (uplink or downlink or flexible) on the TDD spectrum or FDD spectrum. At the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #103e meeting, research work on duplex technology was agreed, and in particular, the SubBand non-overlapping Full Duplex (SBFD) mode at the gNB (NR Node B) side was proposed. In this mode, the same symbol is used for uplink in some frequency resources and for downlink in other frequency resources, so resource utilization is improved and latency is reduced.

[0003] PUSCH (Physical Uplink Shared CHannel) repetition is a technical solution to enhance the reliability of uplink transmission. At the RAN #90 meeting, research work on enhancing PUSCH repetition type A was agreed, and in particular, a repetition transmission counting method based on available uplink time slots was proposed. With this counting method, the number of PUSCH repetitions increases, so the reliability of uplink transmission is improved and the uplink coverage is enhanced. Summary of the Invention

[0004] Reasonable and effective time-domain resource allocation for PUSCH repetition is an important issue to be considered in system design optimization; this application discloses a solution to the above problem. It should be noted that this application can be applied to a variety of wireless communication scenarios, such as scenarios using the SBFD mode, scenarios using other types of full-duplex modes other than SBFD, scenarios using more flexible duplex modes, scenarios only supporting the half-duplex mode, etc., and achieve similar technical effects. In addition, adopting a unified solution for different scenarios (including but not limited to scenarios using the SBFD mode, scenarios using other types of full-duplex modes other than SBFD, scenarios using more flexible duplex modes, scenarios only supporting the half-duplex mode) helps to reduce hardware complexity and cost, or improve performance. Without conflict, the embodiments and features in any node of this application can be applied to any other node. Without conflict, the embodiments and features in the embodiments of this application can be combined with each other arbitrarily.

[0113] As an example, the target symbol set is directly indicated by the start symbol position and the symbol length.

[0114] As an example, the set of target symbols is the set of target symbols indicated by an SLIV (start and length indicator value).

[0115] As an example, the set of target symbols is the set of symbols indicated by an indexed row of a resource allocation table.

[0117] As an example, the first signaling includes a Time domain resource assignment field, and the Time domain resource assignment field in the first signaling indicates a row in a resource allocation table, and this row indicates the set of target symbols.

[0118] As an example, a resource allocation table is predefined.

[0119] As an example, a resource allocation table is defined by Table 6.1.2.1.1-2 or Table 6.1.2.1.1-3 in 3GPP TS 38.214.

[0120] As an example, a resource allocation table is configurable.

[0143] As an example, the M time slots are M consecutive physical time slots.

[0144] As an example, the M time slots are M non - consecutive available slots.

[0145] As an example, based on the available slot count of the terminal, the M time slots are M non - consecutive available slots.

[0146] As an example, the benefits of the above - mentioned method include: by increasing the number of re - transmissions, it is beneficial to improve the reliability of uplink transmission.

[0147] As an example, the PUSCH - Config IE includes a higher - layer parameter availableSlotCounting, and the higher - layer parameter availableSlotCounting indicates that the terminal counts based on available slots.

[0148] As an example, the first PUSCH is a dynamically scheduled PUSCH.

[0149] As an example, the benefits of the above - mentioned method include: being applicable to dynamically granted uplink transmissions.

[0150] As an example, the first PUSCH is a semi - persistently scheduled PUSCH.

[0151] As an example, the benefits of the above - mentioned method include: being applicable to configured - granted uplink transmissions.

[0152] As an example, the benefits of the above - mentioned method include: being beneficial to reducing the latency of uplink transmission.

[0153] As an example, the first PUSCH is a PUSCH of PUSCH repetition Type A.

[0154] As an example, the first PUSCH is a PUSCH of TBoMS (Transport Block processing over Multiple Slots).

[0155] As an example, transmitting the first PUSCH (Physical Uplink Shared Channel) includes: transmitting multiple repetitions of the first PUSCH.

[0158] As an example, the signal transmitted on the first PUSCH includes: the output after at least part of the following operations on at least one bit block: CRC attachment, code block segmentation, code block CRC attachment, channel coding, rate matching, codeblock concatenation, scrambling, modulation, layer mapping, transform precoding, precoding, mapping to virtual resource blocks, mapping from virtual to physical resource blocks, multi-carrier symbol generation, and modulation up-conversion.

[0159] As an example, the M time slots are used for transmitting multiple repetitions of the first PUSCH.

[0160] As an example, each of the M time slots is used for transmitting one repetition of the first PUSCH.

[0161] As an example, each of the M time slots is used for transmitting a part of the first PUSCH.

[0162] As an example, each of the M time slots is used for transmitting a part of one repetition of the first PUSCH.

[0163] As an example, the terminal would transmit the first PUSCH in the M time slots.

[0164] As an example, according to the conditions in Article 9, Article 11.1, Article 11.2A, Article 15, and Article 17.2 of 3GPP TS 38.213, the terminal does not transmit the first PUSCH in one of the M time slots, and the number of time slots determined by the terminal remains the number of the M time slots.

[0165] As an example, the symbol type of a full-duplex symbol is full-duplex, and the symbol type of a non-full-duplex symbol is non-full-duplex.

[0166] As an example, the multiple symbol types at least include full-duplex and non-full-duplex.

[0167] As an example, the multiple symbol types only include full-duplex and non-full-duplex; when a symbol is not a full-duplex symbol, this symbol is a non-full-duplex symbol.

[0168] As an example, the symbol type of a symbol is one of full-duplex and non-full-duplex.

[0169] As an example, the multiple symbol types further include symbol types other than full-duplex and non-full-duplex.

[0170] As an example, the symbol type of a symbol is a symbol type other than full-duplex and non-full-duplex.

[0171] As an example, there does not exist a symbol that is both a full-duplex symbol and a non-full-duplex symbol.

[0172] As an example, when a symbol is indicated as a downlink by the uplink and downlink TDD configuration signaling and is available for uplink transmission, this symbol is a full-duplex symbol.

[0173] As an example, the benefits of the above method include: being beneficial to improving the uplink performance.

[0174] As an example, when a symbol is indicated as an uplink by the uplink and downlink TDD configuration signaling, this symbol is a non-full-duplex symbol.

[0175] As an example, when a symbol is configured to be available for full-duplex operation, this symbol is a full-duplex symbol; when a symbol is configured not to be used for full-duplex operation, this symbol is a non-full-duplex symbol.

[0176] As an example, when a symbol is configured to be available for full-duplex operation, this symbol is a full-duplex symbol; when a symbol is not configured to be available for full-duplex operation, this symbol is a non-full-duplex symbol.

[0177] As an example, the symbols for SBFD (SubBand non - overlapping Full Duplex) operation belong to full - duplex symbols and do not belong to symbols of non - full - duplex symbol type.

[0178] As an example, the determination of the M time slots depends on the symbol types of multiple symbols, including: the determination of the M time slots depends on the symbol types of the symbols in the target symbol set.

[0179] As an example, the determination of the M time slots depends on the symbol types of multiple symbols, including: the criteria for determining whether the first target time slot belongs to the M time slots and for determining whether the second target time slot belongs to the M time slots are different; the symbols in the target symbol set in the first target time slot are non - full - duplex symbols, and the symbols in the target symbol set in the second target time slot are non - full - duplex symbols.

[0257] Example 3

[0258] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3The radio protocol architecture for controlling plane 300 is shown using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first communication node device and the second communication node device, as well as between two UEs, through PHY301. L2 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. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides handover support. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for disordered reception due to HARQ (Hybrid Automatic Repeat Request).

[0271] Example 4

[0272] Example 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the Figure 4 attachment. Figure 4 It is a block diagram of a first communication device 410 and a second communication device 450 that communicate with each other in an access network.

[0273] The first communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0274] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454, and an antenna 452.

[0275] 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 retransmission of 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). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream and then provides it to a different antenna 420.

[0276] 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 signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream for providing to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the Fast Fourier Transform (FFT) to convert the baseband multi-carrier 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 receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the second communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0277] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, the 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 transmit function described at the first communication device 410 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, and implements the L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing. The multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, and after passing through the analog precoding / beamforming operations in the multi-antenna transmit processor 457, provides them to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0278] In the transmission from the second communication device 450 to the first communication device 410, the functions at the first communication device 410 are similar to the receive function described at the second communication device 450 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 receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive 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 a computer-readable medium. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 may be provided to the core network.
