Description

Method and apparatus in a communication node for wireless communication
Technical Field
The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus for resource scheduling.
Background
The scheduling request (Scheduling Request, SR) is used to apply for Uplink (UL) resources. With the continuous evolution of wireless communication technology, small Data packet (Small Data) service is increasingly used. The 3gpp ran #86 conferences decide to develop a "NR (New Radio) INACTIVE state" small packet transmission "Work Item (WI), study the small packet transmission (Small Data Transmission) technique in the RRC (Radio Resource Control ) INACTIVE state (rrc_inactive) state, and the small packet transmission in the RRC CONNECTED state (rrc_connected) also needs to be studied. In addition, in the face of increasingly higher communication demands, 3GPP (3 rd GenerationPartner Project, third generation partnership project) starts to study Non-terrestrial network communication (Non-Terrestrial Network, NTN), and 3GPP lan #80 conferences decide to develop a "NR (new radio, air interface) -supported Non-terrestrial network solution" study item, which is a continuation (RP-171450) of the earlier "NR-supported Non-terrestrial network" study item, in which uplink scheduling enhancement to reduce transmission delay is an important study aspect.
Disclosure of Invention
When a UE (User Equipment) has data to send in rrc_connected state, but there is no uplink resource, an SR needs to be sent to a Base Station to request uplink resource scheduling, the Base Station (BS) receives the SR and allocates a small amount of uplink resource for BSR (Buffer State Report) transmission to the UE, the UE sends the BSR to the Base Station on the allocated resource, and then the Base Station allocates a proper amount of uplink resource for data transmission to the UE according to the data amount in the BSR. The existing SR message cannot distinguish the data volume waiting to be sent by the UE, that is, the uplink resource for data transmission can be obtained after multiple signaling interactions no matter whether the data packet is big or small. If the UE only needs a small amount of data to be sent, more signaling overhead is wasted in the SR scheduling process, and the transmission delay is larger; especially for NTN large delay networks, the delay from transmitting the SR to actually transmitting the data is large. Therefore, an enhancement of SR is required.
In view of the above problems, the present application provides a solution. In the description for the above problems, the ground network communication (Terrestrial Network, TN) scenario is taken as an example; the method and the device are also applicable to scenes such as Non-terrestrial transmission (Non-Terrestrial Network, NTN) and achieve technical effects similar to TN scenes. Furthermore, the adoption of a unified solution for different scenarios also helps to reduce hardware complexity and cost.

Example 4
Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.
The first 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.
The second communication device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.
In the transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to a controller/processor 475 at the second communication device 410. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, a 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 retransmission of 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., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 410, as well as 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-quadrature amplitude modulation (M-QAM). The multi-antenna transmit processor 471 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.
In a transmission from the second communication device 410 to the first communication device 450, each receiver 454 receives a signal at the first communication device 450 through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the second communication device 410 on 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 the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as 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 transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.
In the transmission from the first communication device 450 to the second communication device 410, a data source 467 is used at the first communication device 450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit 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 allocations, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming, with the multi-antenna transmit processor 457 performing digital multi-antenna spatial precoding, after which the transmit processor 468 modulates the resulting spatial stream into a multi-carrier/single-carrier symbol stream, which is analog precoded/beamformed in the multi-antenna transmit processor 457 before being provided to the 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 provides it to an antenna 452.
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 to baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, a controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the UE 450.
