Description

Signal processing method and device

Technical field

The embodiments of the application relate to the field of communication technology.

Background technique

In the fifth generation (5G) or New Radio (NR, New Radio) system, the transmission of some services needs to ensure both low latency and high reliability. These services include, for example, distributed power system control, smart factories, and remote driving. At present, the existing communication systems cannot meet the low latency requirements of these services. Therefore, it is necessary to further reduce the time delay of data transmission on the basis of the existing communication system.

For a single terminal device, especially in the case of a large data stream, the delay of data transmission will be affected by other data transmission. Specifically, due to the limitation of the processing capacity of the terminal device, the data that can be processed or transmitted at the same time is limited.

In the case of a large data stream, since the relatively recent transmission time point is scheduled by the previous data to be transmitted (for example, through the control signaling sent in advance), the data arriving later may face a long delay. Circumstances that can be transmitted. If the data that arrives later needs to ensure low latency according to business requirements, it is unacceptable to encounter the above situation.

As shown in FIG. 1, the communication system 100 may include a network device 101 and

terminal devices

102 and 103. For the sake of simplicity, FIG. 1 only uses two terminal devices and one network device as an example for description, but the embodiment of the present application is not limited to this.

In the embodiment of this application, an enhancement to the data transmission delay is: if the data to be transmitted arriving later has a higher priority (with low delay requirements), the data can try to preempt the allocated data. Time domain resources.

FIG. 2 is an example diagram of two data transmissions with overlapping resources in an embodiment of the present application. As shown in FIG. 2, indication 1 is used to indicate the transmission of data 1, and indication 2 is used to indicate the transmission of data 2; if The priority of the data 2 indicated by the indication 2 is higher than the priority of the data 1 indicated by the indication 1, and the time domain resources of the data 1 may be preempted, so that the sending of the data 1 is cancelled.

As shown in FIG. 4, indication 1 is used to indicate the transmission of data 1, and indication 2 is used to indicate the transmission of data 2; If the device has sufficient capabilities, both data 2 indicated by indication 2 and data 1 indicated by indication 1 can be sent.

For a terminal device to send an uplink signal, when the network device sends two different instructions to the terminal device (for example, Indication 1 and Indication 2 in Figures 2 to 4), for the hybrid service of URLLC and eMBB, the network device does not It must be determined which of the following signals the last uplink signal sent by the terminal device is: the signal corresponding to indication 1, the signal corresponding to indication 2, or the signal corresponding to indication 1 and indication 2.

Therefore, for network devices, according to which spatial direction (or spatial relation) the corresponding uplink signal is received is a problem that needs to be solved. For example, for high frequency bands (such as Frequency Range2), the radio frequency beamforming parameters for network equipment to receive uplink signals need to be determined in advance, and it is not possible to receive data first and then try digital domain demodulation several times like full digital beamforming. .

Similarly, for a terminal device to receive a downlink signal, when the network device sends two different instructions (for example, Indication 1 and Indication 2 in Figures 2 to 4) to the terminal device, for the hybrid service of URLLC and eMBB, the terminal The device may not necessarily be able to determine which of the following signals the last downlink signal sent by the network device is: the signal corresponding to indication 1, the signal corresponding to indication 2, or the signal corresponding to indication 1 and indication 2.

Therefore, for the terminal device, according to which spatial direction (such as QCL assumption or TCI state) to receive the corresponding downlink signal is also a problem to be solved. For example, for high frequency bands (such as Frequency Range 2), the radio frequency beamforming parameters of the terminal device to receive downlink signals need to be determined in advance, and it cannot be the same as the all-digital beamforming that receives the data first and then tries the digital domain solution multiple times.

501: The terminal device is instructed or configured with the airspace information corresponding to the first signal; and

502. The terminal device transmits or receives a second signal at least according to or prioritizes according to the spatial information corresponding to the first signal; wherein the resources of the first signal and the resources of the second signal are in the time domain The above overlaps at least partially.

It is worth noting that Figure 5 above only schematically illustrates the embodiments of the present application, but the present application is not limited thereto. For example, the order of execution among various operations can be appropriately adjusted, and some other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of FIG. 5 above.

In some embodiments, the spatial information includes at least one of the following: spatial relation information; Transmission Configuration Indication (TCI, Transmission Configuration Indication) state (State) information; Quasi-Co-Location (QCL, Quasi-Co-Location) assumption (Assumption) information; but the embodiment of this application is not limited to this, and may also be other information.

For example, the spatial relationship may refer to the relationship between a reference signal and an uplink signal. The reference signal may be an uplink reference signal (for example, Sounding Reference Signal (SRS, Sounding Reference Signal)), or a downlink reference signal (for example, Channel State Information Reference Signal (CSI-RS, Channel State Information Reference Signal), synchronization Signal block (SSB, Synchronization Signal Block), demodulation reference signal (DM-RS, De-Modulation Reference Signal)); the uplink signal can be via PUCCH, Physical Random Access Channel (PRACH, Physical Random Access Channel) or PUSCH The signal sent. The above spatial relationship is usually indicated or configured/validated in FR2 (Frequency Range 2).

For example, the TCI state may be associated with one or two reference signals with respect to a certain QCL type, and the QCL type includes, for example: QCL-TypeA, QCL-TypeB, QCL-TypeC or QCL-TypeD. The reference signal may be an uplink reference signal (for example, SRS), or a downlink reference signal (for example, CSI-RS, SSB, DM-RS); the uplink signal may be a signal sent via PUCCH or PUSCH. The above spatial relationship is usually indicated or configured/validated in FR2.

In some embodiments, the airspace information corresponding to the first signal may be sent by the network device through downlink control information (DCI), that is, it may be dynamically indicated; or, the airspace information corresponding to the first signal may be sent by the network device through wireless Resource control (RRC, Radio Resource Control) messages are sent, that is, they can be indicated or configured semi-statically; alternatively, the airspace information can also be indicated by DCI signaling and RRC signaling; or, the airspace information can be indicated by DCI signaling, MAC- CE signaling and RRC signaling are jointly indicated, but the embodiment of the present application is not limited to this.

In some embodiments, the airspace information corresponding to the first signal may be indicated/configured/pre-configured by the network device for the terminal device, or may be predefined. The airspace information corresponding to the second signal may also be instructed/configured/pre-configured by the network device for the terminal device, or may be predefined. The “prioritize” in the embodiment of the present application means, for example, that for the indicated/configured/preconfigured/predefined airspace information, the airspace information corresponding to the first signal has priority over the airspace information corresponding to the second signal.

In some embodiments, the terminal device receives the airspace information corresponding to the first signal; the terminal device also receives the airspace information corresponding to the second signal; wherein, the terminal device expects (or thinks, hopes, or determines) where the first signal is. The corresponding airspace information is the same as the airspace information corresponding to the second signal, wherein the resources of the first signal and the resources of the second signal at least partially overlap in the time domain; and the terminal device sends or receives the first signal Two signals.

In some embodiments, the terminal device receives the airspace information corresponding to the first signal; the terminal device also receives the airspace information corresponding to the second signal; and the terminal device sends or receives the second signal; wherein, The resources of the first signal and the resources of the second signal at least partially overlap in the time domain; and the spatial information corresponding to the first signal is the same as the spatial information corresponding to the second signal.

In some embodiments, the time domain resources of the first signal and the time domain resources of the second signal overlap at least within a time period. For example, the time period includes one of the following: at least one symbol, at least one sub-slot, at least one slot, at least one subframe, at least one frame ); The embodiments of this application are not limited to this.

In some embodiments, the terminal device reports the first UE capability (UE capability), which means that the terminal device does not send at least two signals at the same time (here, at least two signals refer to: at least two uplink signals; or , At least two downlink signals; or, at least one uplink signal and at least one downlink signal); the terminal device transmits or receives the second signal at least or preferentially according to the spatial information corresponding to the first signal.

In some embodiments, the terminal device reports the second UE capability (UE capability), which means that the terminal device has the ability to transmit at least two signals at the same time (here, at least two signals refer to: at least two uplink signals; or , At least two downlink signals; or, at least one uplink signal and at least one downlink signal); the terminal device still sends or receives the second signal according to the spatial information corresponding to the second signal.

The above embodiments only exemplify the embodiments of the present application, but the present application is not limited to this, and appropriate modifications may also be made on the basis of the above various embodiments. For example, each of the above embodiments may be used alone, or one or more of the above embodiments may be combined.

It can be seen from the foregoing embodiment that the terminal device transmits or receives the second signal at least or preferentially according to the spatial information corresponding to the first signal; wherein the resources of the first signal and the resources of the second signal are at least partially in the time domain. overlapping. As a result, the network equipment and the terminal equipment can reach a consensus on the spatial information of the uplink and downlink signals, thereby avoiding unnecessary link transmission failures.

Embodiments of the second aspect

The embodiment of the present application is based on the embodiment of the first aspect, and the upstream signal is taken as an example for description. The terminal device sends an uplink signal (second signal), and the network device receives the uplink signal (second signal). The first signal (which can be an uplink signal or a downlink signal) in the embodiment of this application can be actually sent, or it can be cancelled because the time domain resource is preempted by the second signal. The embodiment of this application does not limit the performance of the first signal. Actual transmission.

In some embodiments, the first signal belongs to a signal set (represented by S); the time domain resource of the second signal and the time domain resource of any signal in the signal set at least partially overlap in the time domain.

For example, suppose an uplink signal set S={S ₀ , S ₁ , S ₂ , S ₃ …, S _N }, the corresponding time domain resource sets are R ₀ , R ₁ , R ₂ , R ₃ …, R _N, wherein the time domain resource an uplink signal (a first signal) corresponding to R _{i, i} is greater than or equal to 0 and less than or equal to N; Further, for example, time domain resource uplink signal 2 (a second signal) corresponding to R ₀ , the uplink signal 1 and the uplink signal 2 can be the same signal. The above sets overlap in the time domain, that is, R ₀ ∩R ₁ ∩R ₂ ∩R ₃ ∩...∩R _N =R _overlap .

Here, R _overlap represents the overlapping part of the above-mentioned time domain resources, and its size is, for example, 1 symbol, 1 slot, 1 sub-slot, 1 subframe, and 1 frame; this embodiment does not Limited to this, other time periods are also possible.

In the embodiment of the present application, S can be reduced to S', and then the first signal can be selected from S'(for example, randomly selected with equal probability). Thus, the terminal device sends the uplink signal according to the spatial information corresponding to the first signal; the network device receives the uplink signal according to the spatial information corresponding to the first signal.

In some embodiments, the signals in the signal set (may be all signals or at least some of the signals) are data signals. For example, S'=S _data . Among them, S _data is composed of data signals in the set S.

In some embodiments, the data signal has corresponding control information. For example, consider dynamic grant (DG, Dynamic Grant), S'=S _DG . Among them, S _DG is composed of data signals in the set S _data that have corresponding control information (for example, transmitted through PDCCH).

In some embodiments, the time domain interval between the data signal and its corresponding control information is greater than or equal to a threshold. For example, considering UE capabilities, S'= _S'DG . _S'DG is a subset of S _DG . Wherein, S _'DG the signal satisfies the following conditions: a time domain between the control signaling signal a signal which it is scheduled / interval indicated greater than or equal Threshold. The length of the Threshold is based on the UE capability, and/or the length of the Threshold is related to the subcarrier carrier spacing (SCS).

For example, the Threshold refers to the number of shortest Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) symbols from receiving the PDCCH from the terminal device to applying the spatial relationship indicated by the DCI. The terminal device respectively reports the number of OFDM symbols to the network side according to different subcarrier intervals (for example, 60kHz, 120kHz).

In some embodiments, the control information corresponding to the data signal is scrambled by at least one of the following identifiers: C-RNTI, MCS-C-RNTI, SI-RNTI, P-RNTI, RA-RNTI, TC- RNTI; this application is not limited to this. For example, S'=S _RNTI . S _RNTI is a subset of S _DG . The signal in the S _RNTI satisfies the following condition: the signal is indicated by the DCI scrambled by a specific radio network temporary identifier (RNTI, Radio Network Temporary Identifier).

Among them, RNTI includes: cell RNTI (C-RNTI), modulation and coding scheme (MCS, Modulation and Coding Scheme) cell RNTI (MCS-C-RNTI, used to schedule a specific MCS table), configuration scheduling (CS, Configured Scheduling) RNTI (CS-RNTI), System Information (SI, System Information) RNTI (SI-RNTI), Paging RNTI (P-RNTI), Random Access (RA, Random Access) RNTI (RA-RNTI), or Temporary Cell (TC, Temporary Cell) RNTI (TC-RNTI).

In some embodiments, the data signal has no corresponding control information. For example, consider a configured grant (CG, Configured Grant), S'=S _CG . Among them, S _CG is composed of data signals in the set S _data that have no corresponding control information (PDCCH) transmission.

In some embodiments, the signals in the signal set (which may be all signals or at least some of the signals) are control signals. For example, S'=S _control . Among them, S _control is composed of control signals in the set S (for example, through PUCCH).

In some embodiments, the control signal is used to send a scheduling request (SR, Scheduling Request). For example, S'=S _SR ; where, S _SR is a subset of S _control , and S _SR refers to a control signal used to send SR in S _control .

In some embodiments, the control signal is used to carry Hybrid Automatic Repeat reQuest (HARQ, Hybrid Automatic Repeat reQuest) feedback information. For example, S'=S _HARQ . Among them, S _HARQ is a subset of S _control , and S _HARQ refers to a control signal used to carry ACK/NACK information corresponding to PDSCH in S _control .

For another example, consider DG, S'=S' _HARQ . _S'HARQ is a subset of S _HARQ , and the above-mentioned PDSCH has corresponding control information transmission. For another example, the data channel corresponding to the HARQ feedback information does not have corresponding control information.

In some embodiments, the control signal is used to carry channel state information (CSI, Channel State Information) feedback (feedback) information. For example, S'=S _CSI . Among them, S _CSI is a subset of S _control , and S _CSI refers to the control signal used to carry CSI measurement results in S _control .

In some embodiments, the signals in the signal set are signals indicated by control signals. For example, S'=S _controlled ; where S _controlled is composed of signals indicated by the controlled information (for example, through PDCCH) in the set S.

For example, the signal indicated by the control signal includes: an uplink data signal (via PUSCH) scheduled by a downlink control signal (via PDCCH). For another example, the signal indicated by the control signal includes: an uplink control signal (via PUCCH) related to a downlink control signal (via PDCCH) indication, for example, used to carry HARQ feedback information corresponding to a PDSCH scheduled by DCI.

In some embodiments, the signals in the signal set are signals that are not indicated by the control signal. For example, S'=S _no _controlled . Among them, S _no _controlled is composed of signals in the set S except for the signals indicated by the control information (through PDCCH).

For example, the signal indicated by the control signal is a data signal indicated by the control signal. For example, consider the case of CG, S'=S' _no _controlled . Among them, _S'no _controlled is composed of signals in the set S except for the data signals indicated by the control information (through PDCCH).
