Description

BACKGROUND

Technical Field

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a transmission scheme and device for uplink power control reporting in wireless communications.

Related Art

The 5G wireless cellular communication network system (5G-RAN) enhances the uplink power control of UE based on the already-existing Long-Term Evolution (LTE). Compared to LTE, due to the absence of Common Reference Signal (CRS) in the NR system, the measurement of pathloss required for uplink power control shall be performed using Channel State Information Reference Signal (CSI-RS) and SS/PBCH Block (SSB). In addition, the most important feature of the NR system is the introduction of the beam management mechanism. The terminal can communicate with multiple different transmitting and receiving beams, and thus the terminal needs to be able to measure multiple pathlosses corresponding to multiple beams, in which one way of determining the pathloss is to indicate to a certain associated downlink RS resource by means of a Sounding Reference Signal Resource Indicator (SRI) in the DCI.

In the discussion of NR R17, the scenario where multiple Panels are configured on the terminal side has been adopted, and the impact on power control brought about by the introduction of multiple Panels needs to be considered accordingly.

SUMMARY

In the discussion of NR R17, enhancements are made to the terminal's transmissions, and one important aspect is the introduction of two Panels, which can be employed by the terminal to transmit on two transmitting beams at the same time in order to obtain better spatial diversity gain. However, an important indicator for uplink transmission is power control. Whether the same power control parameter is applied for two Panels when adopted simultaneously and one panel when adopted solely, and whether there is dynamic allocation of power between the two Panels will have an impact on the practice of uplink power control under multi-Panel circumstance, and furthermore, the existing reporting mechanism of PHR (i.e., Power Headroom Report) also needs to be reconsidered.

The present application discloses a solution to the above problem of uplink power control in multi-panel scenarios. It should be noted that in the description of the present application, multiple panels are only used as an exemplary application scenario or example: the present application is equally applicable to other scenarios facing similar problems, such as single-panel scenarios, or for different technical fields, such as technical fields other than uplink power control, or the field of measurement reporting, or other non-uplink power control fields such as uplink data transmission, to achieve similar technical results. Additionally, the adoption of a unified solution for various scenarios, including but not limited to multi-panel scenario, contributes to the reduction of hardcore complexity and costs.

In FIG. 3, the radio protocol architecture for a control plane 300 between a first communication node (UE, gNB or, RSU in V2X) and a second communication node (gNB, UE, or RSU in V2X), is represented by three layers, i.e., layer 1, layer 2 and layer 3. The layer 1 (L1) is the lowest layer which performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present application. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between a first communication node and a second communication node via the PHY 301. The L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All these sublayers terminate at the second communication nodes. The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels.

Embodiment 4

FIG. 4 is a block diagram of a first communication device 450 and a second communication device 410 in communication with each other in an access network.

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 second communication device 410, a higher layer packet from a core network is provided to the controller/processor 475. The controller/processor 475 provides functions 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 transport channel, and radio resource allocation of the first communication device 450 based on various priorities. The controller/processor 475 is also in charge of a 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 (i.e., PHY). The transmitting processor 416 performs coding and interleaving so as to ensure a Forward Error Correction (FEC) at the second communication device 410 side and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, which includes precoding based on codebook and precoding based on non-codebook, and beamforming processing on encoded and modulated signals 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, which is later provided to different antennas 420.

In a 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 via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, and 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 reception analog precoding/beamforming on a baseband multicarrier symbol stream provided by the receiver 454. The receiving processor 456 converts the processed baseband multicarrier symbol stream 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 first communication device 450-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 by the second communication device 410 on the physical channel. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 provides functions of the L2 layer. The controller/processor 459 can be associated with the memory 460 that stores program code and data: the memory 460 may 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 transport channel and a logical channel, packet reassembling, decrypting, 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 for processing.

In a transmission from the first communication device 450 to the second communication device 410, at the first 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 node 410 to the first communication node 450, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource 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 a retransmission of a lost packet, and a signaling to the second communication device 410. The transmitting processor 468 performs modulation and mapping, as well as channel coding, and the multi-antenna transmitting processor 457 performs digital multi-antenna spatial precoding, including precoding based on codebook and precoding based on non-codebook, and beamforming. The transmitting processor 468 then modulates generated spatial streams into multicarrier/single-carrier symbol streams. The modulated symbol streams, after being subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457, are provided from the transmitter 454 to each antenna 452. Each transmitter 454 firstly converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 452.

In a transmission from the first communication device 450 to the second communication device 410, the function of the second communication device 410 is similar to the receiving function of 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 a radio frequency signal via a corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be associated with the memory 476 that stores program code and data: the memory 476 may be called a computer readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression, control signal processing so as to recover a higher-layer packet from the first communication device (UE) 450.
