Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to methods and apparatus for reporting power margins. Background Technology

[0002] To effectively utilize radio resources, the gNB's MAC includes a dynamic resource scheduler that allocates physical layer resources for uplink and downlink. This requires the UE to provide a Power Headroom Report (PHR) to support power-aware packet scheduling. The PHR is based on the difference between the nominal UE maximum transmit power and the estimated power for uplink transmission. The 3GPP (3rd Generation Partnership Project) standard TS38.321 defines the triggering conditions for the PHR and the format of the MAC CE used to report it. For Carrier Aggregation (CA), when there is no transmission on the active cell, a virtual report is provided using a reference power.

[0003] Existing carrier aggregation (CA) treats each component carrier (CC) as a serving cell. While existing carrier aggregation can improve the UE's service bandwidth and transmission rate, it has low efficiency in utilizing fragmented spectrum resources. Configuring multiple carriers for the same cell can not only leverage the advantages of existing carrier aggregation but also effectively improve the utilization efficiency of fragmented spectrum resources, representing an important evolution direction for future wireless communication technologies (such as 5G+ or 6G). According to the 3GPP (3rd Generation Partnership Project) standard TS38.300, configuring multiple carriers for the same cell exceeds the scope of 3GPP. Summary of the Invention

[0004] The inventors discovered through research that how to maintain the PHR (Programmable Response Rate) is a problem that needs to be studied if multiple carriers are configured in the same cell.

[0005] To address the aforementioned issues, this application provides a solution. While the example described above uses multiple carriers configured within the same cell, this application does not limit the terminology used for this configuration. For instance, multiple carriers configured within the same cell could be referred to as SCMC (Signal Cell Multiple Carrier). Furthermore, employing a unified solution across different scenarios helps reduce hardware complexity and cost.

[0006] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0007] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS37 series.

[0008] It should be noted that, unless otherwise specified, the embodiments and features in any node of this application can be applied to any other node. Furthermore, unless otherwise specified, the embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

[0009] This application discloses a method used in a first node for wireless communication, characterized by comprising:

[0010] Receive a first information block, wherein the first information block configures multiple frequency elements of a first cell, and any two frequency elements among the multiple frequency elements do not overlap; receive a second information block, wherein the second information block configures a target frequency block, and the target frequency block overlaps with at least some of the frequency elements among the multiple frequency elements, and the target frequency block can be used for uplink transmission;

[0011] Trigger the first PHR;

[0012] The triggering of the first PHR depends on the change of the frequency unit overlapping with the target frequency block.

[0013] When a first cell is configured with multiple frequency units, how to trigger a Pre-HR (Pre-HR) is a problem that needs to be solved. Considering that changes in frequency units will lead to changes in the system bandwidth of the first cell and changes in the target frequency block available for uplink transmission, thus affecting the transmission power, the above method relies on changes in frequency units overlapping with the target frequency block to trigger the first PHR. This is beneficial for power control, assists in the uplink scheduling of the sender of the second information block, and improves the utilization rate of frequency resources.

[0014] According to one aspect of this application, it is characterized by comprising:

[0015] Receive a first signaling instruction, the first signaling instruction indicating at least one frequency element;

[0016] The change in the frequency unit that overlaps with the target frequency block depends on the first signaling.

[0017] As an example, before the first signaling is received, the target frequency block does not overlap with the at least one frequency unit; after the first signaling is received, the target frequency block overlaps with the at least one frequency unit.

[0018] As one embodiment, before the first signaling is received, the target frequency block overlaps with the at least one frequency unit; after the first signaling is received, the target frequency block does not overlap with the at least one frequency unit.

[0019] Determining the changes in frequency units overlapping with the target frequency block is a problem that needs to be solved. The method described above, where the sender of the second information block controls the changes in frequency units overlapping with the target frequency block, allows the sender of the second information block to more flexibly adjust the target frequency block available for uplink transmission, thereby utilizing frequency resources more effectively.

[0020] According to one aspect of this application, it is characterized by comprising:

[0021] Receive a second signaling instruction, which indicates the value of the first timer;

[0022] The change in the frequency unit that overlaps with the target frequency block depends on the expiration of the first timer.

[0023] Determining the changes in frequency units overlapping with the target frequency block is a problem that needs to be solved. The above method adjusts the target frequency block available for uplink transmission using a first timer, requiring no additional signaling indication, making it simple to implement and helping to reduce signaling overhead.

[0024] According to one aspect of this application, it is characterized by comprising:

[0025] In response to the first PHR being triggered, a first PHR MAC (Medium Access Control) CE (Control Element) is sent.

[0026] Wherein, the first PHR MAC CE indicates at least one of the maximum output power or power margin.

[0027] After the first PHR is triggered, how to report the PHR is a problem that needs to be solved. The above method indicates at least one of the maximum output power or power margin through the first PHR MAC CE, which is beneficial for reusing the existing PHR process and reducing the workload of standardization.

[0028] As an example, the first PHR MAC CE indicates the maximum output power and power margin.

[0029] As an example, the first PHR MAC CE indicates the maximum output power.

[0030] As an example, the first PHR MAC CE indicates power margin.

[0031] According to one aspect of this application, the power margin indicated by the first PHR MAC CE is the difference between the maximum output power indicated by the first PHR MAC CE and the estimated power; the estimated power depends on the frequency cells overlapping with the target frequency block.

[0032] Determining the power margin indicated by the first PHR MAC CE is a problem that needs to be solved. Considering that uplink transmission can only be performed on frequency units that overlap with the target frequency block, the above method determines the estimated power based on the frequency units that overlap with the target frequency block. Frequency units that do not overlap with the target frequency block will not participate in the calculation of the estimated power, which can provide a more reasonable power margin to assist the sender of the second information block in resource scheduling.

[0033] According to one aspect of this application, the second information block includes a first sub-information block and a second sub-information block, the first sub-information block configuring a target frequency set, the target frequency set overlapping with each of the plurality of frequency units, and the second sub-information block indicating the target frequency block from the target frequency set.

[0034] Determining the target frequency block is a problem that needs to be solved. The aforementioned method of indicating the target frequency block from the target frequency set facilitates dynamic adjustment of the target frequency block within the target frequency set.

[0035] According to one aspect of this application, the target frequency block is indicated by a first index, which is a non-negative integer or a positive integer.

[0036] The above method indicates the target frequency block through the first index, which is beneficial for the first node and the sender of the second information block to identify the target frequency block, and is especially suitable for scenarios where the number of frequency blocks in the first cell is greater than 1.

[0037] According to one aspect of this application, the target frequency block belongs to a BWP (Bandwidth Part).

[0038] The above method reuses BWP, which is beneficial for forward compatibility.

[0039] The above approach facilitates evolution based on existing protocols and reduces the workload of standardization.

[0040] According to one aspect of this application, it is characterized by comprising:

[0041] Trigger the second PHR;

[0042] The triggering of the second PHR-dependent PHR reporting mode is reconfigured to the first candidate PHR reporting mode; for the first candidate PHR reporting mode, power margin is reported for the frequency unit.

[0043] The above method introduces a new PHR reporting mode for reporting power margins in frequency units, which is beneficial for the sender of the second information block to perform more refined radio resource scheduling and improve frequency resource utilization.

[0044] According to one aspect of this application, it is characterized by comprising:

[0045] In response to the first PHR MAC CE being sent, the partially triggered PHR is cancelled.

[0046] In the above method, some triggered PHRs are not canceled, which is beneficial for triggering new PHRs in a timely manner.

[0047] This application discloses a method used in a second node for wireless communication, characterized by comprising:

[0227] As an example, each of the plurality of frequency units is configured in at least one BWP.

[0228] As one embodiment, the multiple frequency units belong to the same BWP. This method configures multiple frequency units for the same BWP, which is beneficial for improving the frequency resource diversity gain of the BWP.

[0229] As an example, each of the plurality of frequency units is configured with at least one BWP.

[0279] Example 3

[0280] 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 control plane 300 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 as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and cross-area mobility support. The RLC sublayer 303 provides segmentation and reassembly of upper-layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat Request).

[0291] Example 4

[0292] 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 450 and a second communication device 410 communicating with each other in the access network.

[0293] The first 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.

[0294] The second 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.

[0295] In the transmission from the second communication device 410 to the first communication device 450, at the second 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 second communication device 410 to the first 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 first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting 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., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, 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.

[0296] In the 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 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 first 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 second 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 second communication device 410 to the first 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.

[0297] In the transmission from the first communication device 450 to the second communication device 410, at the first 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 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 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 second 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.

[0298] 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 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 first communication device 450 to the second 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.
