Description

A method and apparatus for reporting channel state information in wireless communication Technical Field

[0001] This application relates to methods and apparatus in wireless communication systems, and more particularly to methods and apparatus in wireless communication that support channel state information reporting. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study New Radio (NR) (or 5G). The 3GPP RAN #75 plenary meeting adopted the WI (Work Item) for New Radio technology and began the standardization work for NR.

[0003] Channel Status Information (CSI) reporting is a fundamental and important research area in wireless communication. The basic principle of CSI reporting is that the base station configures Reference Signal (RS) resources for the User Equipment (UE), the UE performs measurements on the RS and calculates the CSI, and then reports it to the base station to assist the base station in performing scheduling and beam management. To adapt to diverse network scenarios and meet different needs, 3GPP has been continuously evolving the CSI reporting process. Summary of the Invention

[0004] The inventors discovered through research that UE-triggered CSI reporting requires further investigation. To address this issue, this application discloses a solution. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined. Although this application is specifically for the Uu air interface, it is equally applicable to the PC5 air interface. Furthermore, while this application is initially intended for UE-triggered CSI reporting scenarios, it is also applicable to other UE-triggered reporting scenarios, including but not limited to physical layer reporting and MAC sublayer reporting. Physical layer reporting includes, but is not limited to, UCI (Uplink Control Information) reporting and L1 (layer 1) measurement reporting; MAC sublayer reporting includes, but is not limited to, BFR (Beam Failure Recovery) reporting, achieving similar technical effects. In addition, using a unified solution for different scenarios helps reduce hardware complexity and cost. Specifically, the explanations of terms, nouns, functions, and variables in this application (unless otherwise specified) can be found in the definitions of the 3GPP specification protocols TS38 and TS37 series.

[0005] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0006] Receive the first signaling;

[0007] Received in the first RS resource set;

[0008] Detect target DCI (Downlink Control Information);

[0009] In response to any event in the first event set, first control information is sent, the first control information indicating a first physical layer channel for first reporting;

[0010] Whether to send the first report on the first physical layer channel is determined based on at least the detection target DCI;

[0011] Wherein, the first signaling indicates that the first report depends on the measurement of the first RS resource set, and the first report indicates channel quality; one of the events in the first event set is: the RSRP of an RS resource in the first candidate RS resource set is better than the RSRP of at least one RS resource in the first RS resource set by more than a first threshold.

[0012] As an example, the first node monitors whether any event in the first event set has occurred.

[0013] As an example, monitoring whether any event in the first event set has occurred depends on measurements of the first RS resource set and the first candidate RS resource set.

[0014] As an example, the time-frequency resources occupied by the first control information are configured.

[0015] As an example, the time-frequency resources occupied by the first control information appear at equal intervals.

[0016] As an example, in the prior art, the UE transmission is uniformly scheduled by the base station, and no transmission conflict will occur; however, in the present invention, the first physical layer channel occupied by the first report is indicated by the first control information, and the first control information is triggered by any event in the first event set. Whether any event in the first event set occurs is determined by the first node itself. That is, the first physical layer channel occupied by the first report is scheduled by the first node, so it is impossible to avoid conflict with the transmission scheduled by the base station.

[0017] As an example, the transmission conflict includes transmission time-frequency resource overlap, or a conflict between transmissions triggered by the base station and those triggered by the UE.

[0018] As an example, the above method can effectively reduce uplink transmission latency compared with the uplink transmission triggered by the UE request and then the base station scheduling in the prior art.

[0019] As an example, the above method can avoid unnecessary reporting, save air interface resources, and achieve the beneficial effect of UE power saving.

[0020] As an example, the above method standardizes the behavior of the UE when a transmission conflict occurs, and a consistent understanding can be obtained between the UE and the base station.

[0021] As an example, the above method can effectively support hybrid UE scheduling and base station scheduling.

[0022] As one example, the first node is a terminal.

[0023] According to one aspect of this application, the above method is characterized by:

[0024] The target DCI includes a first DCI, which indicates a first air interface resource for a second report.

[0025] Wherein, the first air interface resource includes time-domain resources in the first time resource, and the first time resource is associated with the first physical layer channel; the second reporting depends on the measurement for the first RS resource set; the second reporting indicates channel quality.

[0026] As one example, the second report is triggered by the base station, or scheduled.

[0027] As one example, the first report and the second report are triggered sequentially or simultaneously.

[0028] As an example, the above method ensures that the second report includes the information included in the first report by associating the first time resource with the first physical layer channel.

[0029] According to one aspect of this application, the above method is characterized by:

[0030] The target DCI includes a second DCI, which indicates a second air interface resource. The time-domain resources included in the second air interface resource overlap with the time-domain resources occupied by the first physical layer channel.

[0031] According to one aspect of this application, the above method is characterized by:

[0032] The step of determining whether to send the first report on the first physical layer channel based on at least the detected target DCI includes: if the target DCI is not detected, sending the first report on the first physical layer channel.

[0033] As an example, the above method can effectively reduce uplink transmission latency by sending the first report on the first physical layer channel indicated by the first control information.

[0034] As an example, the above method can report channel status information to the base station in a timely manner.

[0035] According to one aspect of this application, the above method is characterized by:

[0036] The step of determining whether to send the first report on the first physical layer channel based on at least the detected target DCI includes: detecting the target DCI and abandoning the sending of the first report on the first physical layer channel; the step of abandoning the sending of the first report on the first physical layer channel includes: sending the second report in the first air interface resource;

[0037] The target DCI is the first DCI.

[0038] As an example, the above method can save air interface resources and achieve the beneficial effect of UE power saving by abandoning the transmission of the first report on the first physical layer channel when the target DCI is detected.

[0039] As an example, the above method can promptly report channel status information to the base station by sending the second report in the first air interface resource.

[0040] As an example, the above method is more robust in sending the second report in the first air interface resources scheduled by the base station, which can improve air interface performance.

[0041] According to one aspect of this application, the above method is characterized by:

[0042] The step of determining whether to send the first report on the first physical layer channel based on at least the detected target DCI includes: detecting the target DCI and abandoning the sending of the first report on the first physical layer channel; the step of abandoning the sending of the first report on the first physical layer channel includes: delaying the sending of the first report to a second physical layer channel;

[0043] The target DCI is the second DCI; the second physical layer channel is indicated by the second control information, and the resources occupied by the first control information and the resources occupied by the second control information are configured by the same set of configuration information.

[0044] As an example, the above method can avoid missing the reporting of channel status information to the base station by sending the first report on the second physical layer channel.

[0045] As an example, the above method improves the robustness of channel state information reporting.

[0046] According to one aspect of this application, the above method is characterized by:

[0047] The first request is cancelled after the first report is sent;

[0048] The step of sending the first control information in response to any event in the first event set includes: triggering the first request in response to any event in the first event set; after the first request is triggered, it is considered to be pending processing, and the first control information is sent while the first request is pending processing.

[0049] As an example, the first request is a scheduling request (SR).

[0050] As an example, the first request is a Channel State Information Reporting Request (CSI report request).

[0051] As an example, the above method ensures that the first report is sent through the first request.

[0052] According to one aspect of this application, the above method is characterized by:

[0053] The first time resource being associated with the first physical layer channel includes: the first time resource includes at least one of the time resource between a first reference time and the time domain resource occupied by the first physical layer channel and the time resource between the time domain resource occupied by the first physical layer channel and the second reference time.

[0054] As an example, the above method ensures the timeliness of reporting through the first time resource.

[0055] As an example, the above method ensures that the first report and the second report depend on the measurement of RS resources in the same first RS resource set through the first time resource.

[0056] According to one aspect of this application, the above method is characterized by:

[0057] The first reference time is the time elapsed after a first interval following the most recent occurrence of one RS resource in the first RS resource set before the time domain resource occupied by the first physical layer channel.

[0058] As an example, the above method reserves post-processing for measurements of RS resources in the first RS resource set through the first interval.

[0059] According to one aspect of this application, the above method is characterized by:

[0060] The second reference time is the time elapsed after the second interval following the latest occurrence of one RS resource in the first RS resource set after the time domain resources occupied by the first physical layer channel.

[0061] As an example, the above method reserves post-processing for measurements of RS resources in the first RS resource set through the second interval.

[0062] This application discloses a first node used for wireless communication, characterized in that it comprises:

[0063] The first receiver receives the first signaling; receives data from the first RS resource set; detects the target DCI.

[0064] A first transmitter, in response to any event in a first set of events, sends first control information, the first control information indicating a first physical layer channel for a first report; and determines whether to send the first report on the first physical layer channel based on at least the detection target DCI.

[0065] Wherein, the first signaling indicates that the first report depends on the measurement of the first RS resource set, and the first report indicates channel quality; one of the events in the first event set is: the RSRP of an RS resource in the first candidate RS resource set is better than the RSRP of at least one RS resource in the first RS resource set by more than a first threshold.

[0066] This application discloses a terminal, characterized in that,

[0067] The terminal includes: one or more processors and memory;

[0068] The memory is coupled to the one or more processors and is used to store computer program code, which includes computer instructions. The one or more processors invoke the computer instructions to cause the terminal to execute the method described above in the first node. Attached Figure Description

[0114] As an example, one RS resource in the first RS resource set is aperiodic in the time domain, that is, the RS resource in the first RS resource set appears at equal intervals.

[0115] As an example, one RS resource in the first RS resource set is semi-persistent in the time domain, meaning that the RS resource in the first RS resource set appears at equal intervals after being activated and before being deactivated.

[0116] As an example, one RS resource in the first RS resource set is aperiodic in the time domain, meaning that the RS resource in the first RS resource set appears only once.

[0142] As a sub-implementation of the above embodiment, the RSRP is L1 (Layer 1)-RSRP.

[0143] As a sub-example of the above embodiment, the RSRP is an L1 filtered RSRP.

[0169] As an example, the first RS resource set depends on at least one TCI state of at least one CORESET in the first CORESET pool, including: the first RS resource set is an RS resource configured with QCL type 'typeD' (type D) indicated by at least one TCI state of at least one CORESET in the first CORESET pool.

[0170] As an example, one of the RS resources in the first RS resource set is the RS resource whose TCI status is indicated by the DCI of the currently scheduled PDSCH (Physical Downlink Shared Channel).

[0177] As a sub-example of the above embodiment, the worst quality RS resource is the RS resource with the smallest RSRP.

[0178] As an example, the RSRP of one RS resource in the first candidate RS resource set being better than the RSRP of at least one RS resource in the first RS resource set by more than a first threshold includes: the RSRP of one RS resource in the first candidate RS resource set being better than the RSRP of the best quality RS resource in the first RS resource set by more than the first threshold.

[0179] As a sub-example of the above embodiments, the RS resource with the best quality is the RS resource with the highest RSRP.

[0180] As an example, the first threshold is configured.

[0181] As an example, the first threshold is pre-configured.

[0182] As an example, the first threshold is fixed.

[0183] As an example, during an evaluation period, the first node evaluates whether the RSRP of each RS resource in the first candidate RS resource set is greater than the first domain value than the RSRP of at least one RSRP in the first RS resource set.

[0184] As an example, the first time window includes at least Q1 evaluation periods, where Q1 is a positive integer not less than 1.

[0185] As an example, the evaluation period is T. Evaluate_CBD_SSB Or T Evaluate_CBD_CSI-RS .

[0186] As an example, when one of the RS resources in the first candidate RS resource set is an SS / PBCH block, the RSRP of the RS is based on the L1-RSRP measured for the SS / PBCH block.

[0187] As an example, when one of the RS resources in the first candidate RS resource set is a CSI-RS, the RSRP of the RS is obtained by subtracting a first power value from the L1-RSRP measured for the CSI-RS. The first power value is the power offset of the CSI-RS to the SS / PBCH block; the first power value is configurable.

[0188] As an example, one of the events in the first event set is: the RSRP of at least one RS resource in the first RS resource set is less than a threshold, wherein the threshold is configured.

[0189] As an example, one of the events in the first event set is: the RSRP of at least one RS resource in the first candidate RS resource set is greater than a threshold, wherein the threshold is configured.

[0190] As an example, one of the events in the first event set is: the RSRP of at least one RS resource in the first candidate RS resource set is greater than a threshold, and the RSRP of at least one RS resource in the first RS resource set is less than another threshold, wherein the first threshold and the other threshold are configured.

[0191] As a sub-implementation of the above three embodiments, the RSRP is L1-RSRP.

[0192] As one embodiment, the first control information indicates a first physical layer channel for first reporting.

[0193] As an example, the first physical channel is reserved for the first report.

[0194] As an example, the first physical channel is dedicated to the first reporting.

[0204] As a sub-implementation of the above embodiments, the first report is MAC CE.

[0205] As a sub-implementation of the above embodiments, the first report is carried in a MAC PDU (Protocol Data Unit).

[0206] As one example, the first control information includes 1 bit.

[0207] As a sub-implementation of the above embodiments, the frequency domain resources occupied by the first physical layer channel are configured; the time interval between the time domain resources occupied by the first physical layer channel and the time domain resources occupied by the first control information is configured.

[0208] As a sub-implementation of the above embodiments, the time-frequency resource occupied by the first physical layer channel is a time-frequency resource following the time-domain resource occupied by the first control information, and the time-frequency resource is one of the periodic time-frequency resources, which is configured.

[0210] As an example, the first control information indicates partial information about the resources occupied by the first physical layer channel, and the remaining information about the resources occupied by the first physical layer channel is configured.

[0211] As a sub-implementation of the above embodiments, the above method can reduce the number of bits of the first control information and save air interface transmission resources.

[0212] Specifically, for example, the resources occupied by the first physical layer channel include time-domain resources and frequency-domain resources. The first control information indicates the time-domain resources. For example, the first control information includes 3 bits, indicating a maximum of 8 time-domain resources. The maximum of 8 time-domain resources can be obtained by looking up a table, or they can be the 8 uplink time slots following the time-domain resources occupied by the first control information. The frequency-domain resources are configured.

[0213] As one embodiment, the first control information indicates all information about the resources occupied by the first physical layer channel.

[0214] As one embodiment, the resources occupied by the first control information, or the resources occupied by the first physical layer channel, are air interface resources.

[0215] As an example, the air interface resources include at least one of time domain resources, frequency domain resources, spatial domain resources, or code domain resources.

[0216] As an example, the first control information indicates that the resources occupied by the first physical layer channel include at least one of time-domain resources, frequency-domain resources, spatial-domain resources, or code-domain resources.

[0217] As one embodiment, the first control information is used to schedule the transmission of the first physical layer channel that was first reported.

[0218] As a sub-implementation of the above embodiments, the above method implements uplink transmission scheduled by the UE, which can reduce uplink transmission latency.

[0219] As an example, it is determined whether to send the first report on the first physical layer channel based on at least the detection target DCI.

[0220] Specifically, the first control information indicates the first physical layer channel for the first report, but whether the first report is sent on the first physical layer channel depends on the result of at least the detection target DCI.

[0221] As one embodiment, determining whether to send the first report on the first physical layer channel based on at least the detection target DCI includes: determining whether to send the first report on the first physical layer channel based on the detection target DCI.

[0222] As an example, determining whether to send the first report on the first physical layer channel based on at least the detection target DCI includes: in addition to determining whether to send the first report on the first physical layer channel based on the detection target DCI, determining whether to send the first report on the first physical layer channel also includes determining whether to send the first report on the first physical layer channel based on whether the first node is in a first state.

[0223] As an example, when it is determined according to the detection target DCI that the first report should be sent on the first physical layer channel, but the first node is in the first state, it is determined not to send the first report on the first physical layer channel; when it is determined according to the detection target DCI that the first report should be sent on the first physical layer channel, and the first node is not in the first state, it is determined to send the first report on the first physical layer channel.

[0229] As an example, the first state is that the timeAlignmentTimer is not running, and the timeAlignmentTimer is associated with the TAG (Timing Advance Group) to which the serving cell belongs.

[0230] As an example, the first signaling indicates that the first reporting depends on the measurement of the first RS resource set.

[0231] As an example, the first signaling indicates that the first report also depends on measurements of other RS ​​resources outside the first RS resource set.

[0232] As an example, the other RS ​​resources outside the first RS resource set are configured by RRC.

[0233] As an example, the other RS ​​resources besides the first RS resource set include the first candidate RS resource set.

[0236] As one example, the first report indicates channel quality.

[0237] As one embodiment, the first report explicitly indicates the channel quality, or the first report implicitly indicates the channel quality.

[0238] Specifically, when the first report includes the channel quality, the first report explicitly indicates the channel quality; when the first report does not include the channel quality, the first report implicitly indicates the channel quality; the implicit indication of the channel quality includes the channel quality being greater than or less than a configured threshold.

[0239] As an example, the channel quality is the reception quality in the RS resources.

[0263] Example 3

[0264] Example 3 illustrates a schematic diagram of the wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in Figure 3. Figure 3 is a schematic diagram illustrating an embodiment of the wireless protocol architecture for the user plane 350 and control plane 300. Figure 3 shows the wireless protocol architecture of the control plane 300 of the UE and gNB 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. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the UE and gNB through PHY 301. L2 layer 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, which terminate at the gNB on the network side. PDCP sublayer 304 provides data encryption and integrity protection, and also supports inter-gNB mobility for UEs. RLC sublayer 303 provides packet segmentation and reassembly, implements retransmission of lost packets via ARQ, and also provides duplicate packet detection and protocol error detection. MAC sublayer 302 provides mapping between logical and transport channels and multiplexing of logical channel identities. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among UEs. MAC sublayer 302 is also responsible for HARQ (Hybrid Automatic Repeat Request) operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the gNB and the UE. Although not illustrated, the UE's control plane 300 may also have a V2X layer above the RRC sublayer 306. The V2X layer is responsible for generating PC5 QoS parameter sets and QoS rules based on the received service data or service requests. It generates a PC5 QoS flow corresponding to the PC5 QoS parameter set and sends the PC5 QoS flow identifier and the corresponding PC5 QoS parameter set to the AS (Access Stratum) layer for the AS layer to perform QoS processing on data packets belonging to the PC5 QoS flow identifier. The V2X layer also includes a PC5-Signaling Protocol sublayer, which is responsible for indicating to the AS layer whether each transmission is a PC5-S transmission or a V2X service data transmission.The wireless protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The wireless protocol architecture in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce wireless transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and data radio bearers (DRBs) to support service diversity. The UE's radio protocol architecture in the user plane 350 may include some or all of the protocol sublayers of SDAP sublayer 356, PDCP sublayer 354, RLC sublayer 353, and MAC sublayer 352 at the L2 layer. Although not illustrated, the UE may also have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).

[0278] Example 4

[0279] Example 4 illustrates a hardware module schematic diagram of a communication device according to an embodiment of this application, as shown in Figure 4. Figure 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.

[0280] 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.

[0281] The second communication device 410 includes a controller / processor 475, a memory 476, a data source 477, 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.

[0282] 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 or from the data source 477 are provided to the controller / processor 475. The core network and data source 477 represent all protocol layers above the L2 layer. 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, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for 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.

[0283] 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 transmission and logical channels to recover the upper-layer data packets from the second communication device 410. 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.

[0284] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, upper-layer data packets are provided to the controller / processor 459 using a data source 467. 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 the logical and transport channels, 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.

[0285] 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 function. The controller / processor 475 implements the L2 layer function. The controller / processor 475 may be associated with a memory 476 storing 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 the upper-layer data packets from the first communication device 450. Upper-layer data packets from the controller / processor 475 can be provided to the core network or all protocol layers above the L2 layer, and various control signals can also be provided to the core network or L3 for L3 processing.

[0474] As an example, the first request is an SR (scheduling request).

[0475] As an example, the first request is a procedure.

[0476] As an example, the first request is considered pending after it is triggered, until it is cancelled.

[0477] As an example, the first request is considered pending after it is triggered, and the first control information is sent while the first request is pending.

[0478] As an example, the time-frequency resources occupied by the first control information occur periodically.

[0479] As an example, after the first request is triggered, the first node selects one of the periodic time-frequency resources to send the first control information.

[0480] As an example, the first control information is a positive SR.

[0481] As an example, the positive SR is a signal.

[0482] As an example, when the first node sends an SR, the SR is the positive SR.

[0483] As a sub-implementation of the above three embodiments, the first request is SR.

[0484] As an example, the resources occupied by the first control information are allocated to the first request.

[0485] As one example, the resources occupied by the second control information are configured for the first request.

[0486] As an example, the resource configured for the first request is dedicated to CSI reports.

[0490] As an example, the resource configured for the first request is a PUCCH resource.

[0491] As an example, the first request is cancelled after the first report is sent.

[0492] As one embodiment, the first report is sent on the first physical layer channel or on the second physical layer channel.

[0493] As an example, any event in the first event set is used to trigger the first request. After the first request is triggered, it is considered pending. While the first request is pending, the first control information is sent. After the first control information is sent, the first request is canceled. Herein, the first request is an SR or a CSI report request.

[0494] As an example, any event in the first event set is used to trigger the first request. After the first request is triggered, it is considered pending. While the first request is pending, the first control information and the second control information are sent. After the first report is sent, the first request is canceled. The first report is not sent on the first physical layer channel. The first control information and the second control information each occupy one time-frequency resource that is adjacent in the time domain in the periodic time-frequency resources.

[0495] As an example, any event in the first event set is used to trigger the first request. After the first request is triggered, it is considered to be pending. The first control information is sent while the first request is pending. The first request is canceled after the second report is sent. The first report is not sent on the first physical layer channel.

[0496] In Case A of Implementation 9, the first report is sent on the first physical layer channel indicated by the first control information, and the first request is cancelled after the first report is sent.

[0497] In Case B of Implementation Example 9, the first report was not sent on the first physical layer channel indicated by the first control information; the first report was sent on the second physical layer channel indicated by the second control information, and the first request was cancelled after the first report was sent.

[0498] In Example 9, when the first request is an SR, backward compatibility can be effectively supported.

[0499] Example 10

[0500] Example 10 illustrates a schematic diagram of the relationship between a first RS resource set, a first physical layer channel, a first reference time, and a first interval according to an embodiment of this application, as shown in Figure 10. In Figure 10, an unfilled rectangle represents an RS resource in the first RS resource set, and a rectangle filled with diagonal lines represents a first physical layer channel.

[0501] As an example, the first time resource depends on the occurrence time of two time-adjacent RS resources in the first RS resource set.

[0502] As an example, the duration of the first time resource depends on the time interval between two time-adjacent RS resources in the first RS resource set.

[0503] As an example, the duration of the first time resource is determined based on the occurrence interval of two adjacent RS resources in the first RS resource set in the time domain.

[0504] As an example, the duration of the first time resource is no greater than the time interval between two adjacent RS resources in the first RS resource set.

[0505] As an example, the duration of the first time resource is equal to the time interval between two adjacent RS resources in the first RS resource set.

[0506] As one embodiment, the first time resource being associated with the first physical layer channel includes: the first time resource includes time resources between a first reference time and the time domain resources occupied by the first physical layer channel.

[0507] As an example, the time-domain resources occupied by the first physical layer channel include at least one symbol.

[0508] As an example, the symbol is an OFDM symbol.

[0509] As an example, the symbol is a single-carrier symbol.

[0510] As one embodiment, the first time resource includes the time resource between the first reference time and the time domain resource occupied by the first physical layer channel, including: the first time resource includes the time resource between the first reference time and the start time of the time domain resource occupied by the first physical layer channel.

[0513] As an example, the first reference time is the time elapsed after a first interval following the most recent occurrence of one RS resource in the first RS resource set before the time domain resource occupied by the first physical layer channel.

[0514] As an example, the first reference time is the time elapsed between the end time of one of the RS resources in the first RS resource set that most recently appeared before the time domain resources occupied by the first physical layer channel and the first interval.

[0515] As an example, the end time of an RS resource in the most recently occurring first RS resource set is the end time of the symbols included in that RS resource.

[0516] As an example, no RS resource in the first RS resource set will appear between the first reference time and the start time of the time domain resources occupied by the first physical layer channel.

[0517] As an example, the first physical layer channel does not overlap in the time domain with one of the most recently occurring RS resources in the first RS resource set.

[0518] As an example, the first interval is equal to 0.

[0519] As an example, the first interval is greater than 0.

[0520] As one example, the first interval is related to the capabilities of the first node.

[0521] As an example, the first interval is configurable.

[0522] As an example, the first interval is used for measurement and post-processing of one RS resource in the first RS resource set.

[0523] As one example, the post-processing includes L1 filtering.

[0524] As one example, the post-processing includes physical layer processing.

[0525] As an example, the post-processing includes MAC sub-layer processing, wherein the second report is either a BFR MAC CE or a Truncated BFR MAC CE.

[0526] As an example, in the first interval, the measurement of one of the RS resources in the first RS resource set that most recently appeared before the time domain resource occupied by the first physical layer channel has not yet yielded a measurement result, or has not yet generated a reporting content.

[0527] As an example, when the first time resource includes the time resource between the first reference time and the time domain resource occupied by the first physical layer channel, the transmission time of the second report is not later than the time domain resource occupied by the first physical layer channel, and both the first report and the second report depend on the measurement for the same first RS resource set, the first report is not sent, which can save air interface resources and obtain the beneficial effect of UE power saving.

[0532] As an example, the second reference time is the time elapsed between the end time of the most recent RS resource in the first RS resource set after the time domain resources occupied by the first physical layer channel and the second interval.

[0533] As an example, the end time of an RS resource in the most recently appearing first RS resource set is the end time of the symbols included in that RS resource.

[0534] As an example, no RS resource in the first RS resource set will appear between the start time of the time domain resource occupied by the first physical layer channel and the second reference time.

[0535] As an example, no RS resource in the first RS resource set will appear between the end time of the time domain resources occupied by the first physical layer channel and the second reference time.

[0536] As an example, the first physical layer channel does not overlap in the time domain with one of the most recently appearing RS resources in the first RS resource set.

[0537] As an example, the second interval is equal to 0.

[0538] As an example, the second interval is greater than 0.

[0539] As one embodiment, the second interval is configurable.

[0540] As an example, the value of the first interval is the same as the value of the second interval.

[0541] As an example, in the second interval, the measurement of one of the RS resources in the first RS resource set that appears most recently after the time domain resources occupied by the first physical layer channel has not yet yielded a measurement result, or has not yet generated a reporting content.

[0542] As an example, when the first time resource includes the time resources between the time domain resources occupied by the first physical layer channel and the second reference time, the transmission time of the second report is equal to or later than the time domain resources occupied by the first physical layer channel, and both the first report and the second report depend on the measurement for the same first RS resource set, the first report is not sent, which can save air interface resources and achieve the beneficial effect of UE power saving. At the same time, the transmission of the second report based on base station scheduling is more robust and can improve air interface performance.

[0545] As a sub-implementation of the above embodiments, the first time resource consists of continuous time resources, and the first physical layer channel does not overlap with one of the most recently occurring RS resources in the first RS resource set in the time domain.
