Patent Application
20250008530
The present application relates to transmission methods and devices in wireless communication systems, and in particular to a transmission method and device for multicarrier scheduling in wireless communications.
Both LTE (Long-Term Evolution) and 5G wireless cellular communication network systems support the scenario where multiple carriers are scheduled at the same time. In the multicarrier scheduling scenario, the base station increases the transmission rate by transmitting multiple Downlink Control Information (DCI) to schedule Physical Downlink Shared Channels (PDSCHs) on multiple carriers. A feature in the multicarrier scheduling is that each PDSCH requires one DCI for scheduling, and one DCI cannot schedule multiple PDSCHs located on multiple carriers at the same time.
In the discussion of NR R17, the topic of scheduling a PDSCH or PUSCH (Physical Uplink Shared Channel) on multiple carriers based on a single DCI was set up, and accordingly, the solution of how to schedule the PDSCH or PUSCH on multiple carriers through a DCI needs to be studied and discussed.
An important enhancement in 5G NR is the introduction of the concept of BWP (Bandwidth Part), a serving cell often comprises multiple BWPs, each BWP can be configured with a different SCS (Subcarrier Spacing) or independently with DL SPS (Semi-persistent Scheduling) or with configured UL Grant Type 2 scheduling, and the base station uses DCI (Downlink Control Information) to activate or release one or multiple DL SPSs or uplink Configured Grant functions.
When a DCI is capable of scheduling PDSCH or PUSCH transmission on multiple carriers, a DCI should also be capable of activating or releasing DL SPS or uplink configured grant on multiple carriers, and thus how to implement the above functions based on existing DCI formats and protocol architectures is something that needs to be investigated and addressed.
The present application discloses a solution for the multicarrier scheduling scenario described above. It should be noted that in the description of the present application, multicarrier is only used as a typical application scenario or example; the present application is equally applicable to other scenarios facing similar problems, e.g., single-carrier scenarios, or for different technical fields, e.g., technical fields other than dynamic scheduling, and other non-dynamic scheduling fields, such as measurement reporting, control signaling transmission, where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios, including but not limited to scenarios of multi-panel, contributes to the reduction of hardware complexity and costs.

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device in the present application, as shown in
The first communication device 450 comprises 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.
The second communication device 410 comprises 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.
In a transmission from the second communication device 410 to the first communication device 450, at the first communication device 410, a higher layer packet from the core network is provided to a controller/processor 475. The controller/processor 475 provides a function of the L2 layer. 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, and multiplexing between a logical channel and a transmission channel, and radio resources allocation for the first communication device 450 based on various priorities. The controller/processor 475 is also responsible for retransmission of a lost packet and a signaling to the first communication device 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the L1 layer (that is, PHY). The transmitting processor 416 performs coding and interleaving so as to ensure an FEC (Forward Error Correction) at the second communication device 410, and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming on encoded and modulated symbols to generate one or more spatial streams. The transmitting processor 416 then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multicarrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multicarrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream. Each radio frequency stream is later provided to different antennas 420.
In a transmission from the second communication device 410 to the first communication device 450, at the second communication device 450, each receiver 454 receives a signal via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs receiving analog precoding/beamforming on a baseband multicarrier symbol stream from the receiver 454. The receiving processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any the first communication device-targeted spatial stream. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted on the physical channel by the second communication node 410. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 performs functions of the L2 layer. The controller/processor 459 can be connected to a memory 460 that stores program code and data. The memory 460 can be called a computer readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between a transmission channel and a logical channel, packet reassembling, decryption, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer, or various control signals can be provided to the L3 layer for processing.
In a transmission from the first communication device 450 to the second communication device 410, at the second communication device 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of 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 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transmission channel based on radio resources allocation so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for retransmission of a lost packet, and a signaling to the second communication device 410. The transmitting processor 468 performs modulation mapping and channel coding. The multi-antenna transmitting processor 457 implements digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, as well as beamforming. Following that, the generated spatial streams are modulated into multicarrier/single-carrier symbol streams by the transmitting processor 468, and then modulated symbol streams are subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457 and provided from the transmitters 454 to each antenna 452.
