Description

Signal transmission, reception and transmission and devices

technical field

The present invention relates to the communication field, in particular, to a signal sending, receiving and sending device.

Background technique

In Long-Term Evolution (LTE for short), there are many periodic reference signals, such as synchronization signal, cell reference signal, channel measurement reference signal, uplink sounding reference signal, etc. To receive or transmit these periodic reference signals. The configuration of the periodic reference signal is simple, and only requires the base station to use high-layer signaling to configure semi-statically, without additional dynamic signaling notification. However, periodic reference signal transmission will bring a large overhead to the system. Therefore, some aperiodic reference signals have entered into LTE at the same time, such as aperiodic uplink sounding reference signals. The base station can configure one or more sounding reference signal configurations with high-level signaling. The configuration parameters include transmission bandwidth, time-frequency position, and sequence cycle. Shift and other parameters, and then the base station can decide whether to trigger the transmission of the uplink sounding reference signal in the physical layer control region according to the requirement. This is the aperiodic sounding reference signal.

In 5G (new radio), due to the increase in user data volume requirements, in order to reduce overhead, especially the overhead of sounding reference signals, it is a trend to introduce aperiodic reference signals. For example, an aperiodic channel sounding reference signal.

In addition, LTE does not require beam reference signals. This is because LTE base stations or users often use a very wide radio frequency beam to achieve cell-level coverage when sending reference signals. Fig. 1-a is a cell-level coverage diagram of radio frequency beams when a reference signal is sent in the related art, as shown in Fig. 1-a. Because the carrier frequency used by LTE is basically below 6 GHz, the wide radio frequency beam formed by multiple antenna elements can cover the entire cell. In 5G, not only the carrier frequency band below 6GHz must be supported, but also the frequency band above 6GHz, such as 60GHz. Due to the very large large-scale path loss in the high frequency band, this brings great challenges to wireless communication. However, due to the high center frequency and short wavelength in the high frequency band, the base station can accommodate a large number of antennas and use multiple antennas to form very narrow beams to form beamforming gains. Therefore, narrow radio frequency beamforming has almost become an indispensable technology for enhancing cell coverage in high frequency bands. As for which beam is configured for the user, the base station may be required to send a beam reference signal for the user to measure the best beam. Figure 1-b is a schematic diagram of different reference signals corresponding to different beam directions in the related art. As shown in Figure 1-b, the base station can trigger or periodically send beam reference signals, where different reference signals correspond to different beam directions. After measuring the beam reference signal, the UE can feed back one or more optimal beam sequence numbers to the base station, so that the base station can use the optimal beam to send data to a specific user when sending data subsequently.

As mentioned above, the introduction of non-periodical transmission of beam reference signals will also save the pilot overhead of the system.

In addition, for the beam measurement reference signal and other similar reference signals, the dynamic activation method may also be introduced in 5G. For example, the base station can use physical layer dynamic signaling to activate the transmission of the beam reference signal. After activation, the base station will send periodic or multiple beam reference signals according to the high-layer signaling configuration.

Figure 2-a is a schematic diagram of the triggering of the downlink reference signal in the related art. As shown in Figure 2-a, if it is the triggering of the downlink reference signal, after the base station triggers a certain reference signal in the physical layer control area of subframe n, the base station will It will be sent on subframe n+m, and at this time it is assumed that subframe n+m is a downlink subframe. If the uplink reference signal is triggered, after the base station triggers a certain reference signal in the physical layer control area of subframe n, the user will send in subframe n+m, where subframe n+m includes the uplink transmission area.

In order to support flexible subframe configuration, generally, there may be multiple candidate values of m, such as 0, 1, 2, and 3. The base station will dynamically notify the specific value of m when triggering the reference signal. If m=0, then the DCI triggering the reference signal and the transmitted reference signal are in one subframe.

Whether the UE needs to feed back the measurement result and in which subframe the measurement result may be fed back may also need to be included in the dynamic signaling. Generally, the base station can use dynamic signaling to notify the user to feed back the measurement result to the base station in k subframes after measuring the reference signal. Figure 2-b is a schematic diagram of measurement result feedback in related technologies. As shown in Figure 2-b, after the base station triggers a downlink measurement reference signal in the physical layer control area of subframe n, the base station will At the same time, the base station triggers the measurement result feedback in subframe n, so that the user will send the measurement result to the base station in subframe n+m+k.

In order to support flexible subframe configuration, generally, there may be multiple candidate values of k, such as 0, 1, 2, ..7. For example, if k=0 is a downlink subframe, then the base station cannot configure k=0, because it is impossible for the user to use the downlink subframe to send uplink data at this time.

This kind of dynamic trigger reference signal and feedback brings great flexibility to the system, but also brings certain troubles to the system. As shown in Figure 2-a, the base station triggers the transmission of reference signal 1 on subframe n+3 in subframe n, and at this time m=3, and the base station triggers the transmission of reference signal 2 on subframe n+1 It is sent on subframe n+3, and m=2 at this time. In this way, if the resource positions of the reference signal 1 and the reference signal 2 overlap, it will bring troubles to the user's measurement and feedback.

Aiming at the above-mentioned problems existing in related technologies, no effective solution has been found yet.

Example 3

This embodiment is an optional embodiment according to the present invention, and is used to describe the application in detail in conjunction with specific examples:

This embodiment proposes a method for reference signal triggering and its feedback prioritization, including:

The sending end triggers signal s1 to be sent or received on time unit n1+m1 in time unit n1, and

And the sending end triggers the signal s2 to be sent or received in the time unit n2+m2 in the time unit n2. If the resource positions of the signals s1 and s2 overlap, the signals s1 and s2 are received or sent according to a certain priority rule.

If the signals s1 and s2 are reference signals, they include channel measurement reference signals, beam reference signals, uplink sounding reference signals, precoded channel measurement reference signals, and the like.

The foregoing one time unit may be one subframe, or one minimum scheduling time domain unit. The downlink sending end refers to the base station, and the receiving end refers to the user terminal, while the uplink sending end refers to the user, and the receiving end refers to the base station. Both uplink and downlink are triggered by the base station. For these reference signals, the base station can use high-level signaling to configure the resource position of the reference signal in a subframe, that is, the frequency position, such as which time-domain Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing, referred to as For OFDM) symbols, there is also the bandwidth length, such as the fraction of the system bandwidth for reference symbols, and the density of reference symbols, such as sending every Physical Resource Block (PRB for short), or every Two PRBs are sent once and so on. After high-level signaling configures these parameters, the base station can use the downlink control information (Downlink Control Information, DCI) bit to trigger whether to send the reference signal, and in which subframe to send it later. Of course, the base station can configure multiple reference signal configuration parameters for the user through RRC signaling, and then the base station can trigger one of them through bit information of the DCI.

That is to say, the information contained in the DCI by the base station includes whether to trigger a certain reference signal and in which subframe the reference signal will be sent later. As shown in Figure 2-a, in subframe n, the base station uses DCI to trigger the downlink measurement reference signal, and then at the same time, the DCI contains some information bits to tell the value of m to the user. In subframe n+m, the base station will The measurement reference signal is sent. Parameters such as the time-frequency position, bandwidth, and density of the measurement reference signal need to be known according to high-layer signaling instructions.

FIG. 9 is a schematic diagram of priority sorting in this embodiment. As shown in FIG. 9 , the sending time unit n1 is subframe n, and the sending unit n2 is subframe n+1, m1=3, m2=2. The base station triggers the measurement reference signal s1 on the subframe n1, and triggers the measurement reference signal s2 on the subframe n2. s1 and s2 can be the same type of measurement reference signal, for example, both are downlink channel measurement reference signals (Channel State Information-Reference Signals, CSI-RS), and high-level signaling configures the time-frequency position, bandwidth, density, etc. of s1 and s2 The parameters can be the same or different. If the time-frequency positions of s1 and s2 overlap, then according to the priority rule, the reference signal with low priority can be discarded. That is to say, n1+m1=n2+m2 at this time, and the base station only sends the reference signal with the highest priority, and discards the reference signal with the lowest priority.

Of course, s1 and s2 are reference signals of the same type, but high-level signaling configurations may be different. For example, for CSI-RS, multiple configurations are configured in high-level signaling. In subframe n1, DCI triggers one configuration parameter, and in subframe n2, DCI triggers another configuration parameter. However, if the two configurations If the time-frequency positions of the reference signals indicated by the parameters overlap, the reference signals with low priority also need to be discarded.

If s1 and s2 are different types of reference signals, for example, s1 is a beam reference signal, and s2 is a channel measurement reference signal, if the time-frequency positions of the two reference signals configured by the high layer overlap, it is still necessary to send only the priority in order of priority A reference signal with a high priority is discarded while a reference signal with a low priority is discarded.

It should be noted that this embodiment is not only applicable to two reference signal transmission conflicts.

The predefined reference signal sorting method can be sorted according to the subframe where the DCI trigger is located. For example, the reference signal triggered after the DCI has a high priority, as shown in Figure 9. Since the DCI trigger corresponding to s2 is in the subframe n2, and the subframe Frame n2 is late, so s2 has high priority. Therefore, the base station only sends the measurement reference signal s2 at the time of subframe n2+m2 or n1+m1. According to the sorting method, the type of the reference signal can be ignored, and the priority can be arranged completely according to the order of the subframes in which the DCI is located.

Optionally, the user does not want the reference signal triggered by the base station to be sent or received in the same time unit. For example, for the above-mentioned downlink channel measurement reference signal and beam reference signal, if the resource positions of s1 and s2 overlap, the user does not want n2+m2=n1+m1.

The resource locations of the reference signals overlap, which means that in the same transmission time unit, the time-domain symbols where the reference signals are located and the frequency-domain resource locations are all or partially overlapped, as shown in Figure 9 .

Optionally, the predefined reference signal sorting method may be prioritizing according to the densities of s1 and s2 , or the bandwidth length, or the number of ports. For example, if the bandwidth length of the s1 signal is greater than that of s2, then the priority of s1 is high. If their time-frequency positions overlap, the actual triggering of s2 will be invalid. That is to say, no s2 signal is actually sent at the time of subframe n2+m2.

For multiple types of measurement reference signal triggers, and the priority ordering method for multiple trigger overlaps of each measurement reference signal, optional, if s1 and s2 are different types of reference signals, the type of signals s1 and s2 can be selected first Perform priority sorting, and then perform priority sorting according to the order of n1 and n2. For example, the priority of the beam reference signal is higher than that of the channel measurement reference signal. If s1 is the beam measurement reference signal and s2 is the CSI-RS, then even if n2 is later, the priority of s1 is still higher than that of s2. Optionally, if s1 and s2 are different types of reference signals, priority is firstly sorted according to the density of signals s1 and s2, or the bandwidth length, or the number of ports, or the sequence of corresponding n1 and n2. Then perform priority sorting according to the types of signals s1 and s2.

The priority sorting rules may be different for each user, and in this case, the base station needs to configure it for each user through high-level signaling. For example, users 1 are sorted according to the DCI triggering time, regardless of the type of reference signal. For user 2, the priority of the beam reference signal is high, but the priority of the CSI-RS is low, and the priority is firstly sorted according to the type of the reference signal and then sorted according to the sequence of the DCI triggering time.

For different transmission areas, Figure 10 is a schematic diagram of the multiplexing of unused transmission areas in this embodiment, such as Figure 10, two transmission areas are multiplexed in the system bandwidth in the frequency domain, and the subcarrier spacing of transmission area 1 and transmission area 2 is different , so the length of each time-domain OFDM symbol is also different, resulting in different subframe lengths. In this way, the base station can separately configure the priority rules of the two transmission areas through high-layer signaling.

The candidate values of m1 and m2 are configured through high-layer signaling, and the candidate values of m may be different for different users. m indicates that the measurement reference signal is sent m subframes after the DCI trigger time. For example, for user 1, the candidate values of m are 0, 1, 2, 3. For user 2, the values of m are 0, 1. Since different users have different processing capabilities and require different processing delays, different candidate values of m can bring flexibility. In addition, for users with high latency requirements, the candidate value of m can be configured smaller, and for users with low latency requirements, more candidate values for m can be configured to increase flexibility. Of course, even for the same user, for different transmission areas, the base station separately configures different m candidate values through high-layer signaling. It is worth noting that the flexible m-candidate value approach is not limited to reference signal ranking methods. That is, even if the system does not sort these reference signals, the flexible m-candidate value scheme can bring benefits to the system.

The signals s1 and s2 include the feedback of the measurement result of the channel measurement reference signal, the feedback of the measurement result of the beam reference signal, the feedback of the measurement result of the precoding channel measurement reference signal, and the like. Feedback of these measurement results can be transmitted on the uplink data channel or on the uplink control channel, and the corresponding resource position overlap or conflict is the conflict of the uplink data channel and the conflict of the uplink control channel respectively.

After the base station triggers the measurement reference signal at the time of subframe n, and notifies the user that the measurement reference signal will be sent at the time of subframe n+m, then the user will feed back the measurement result to the base station at the time of subframe n+m+k. The value of k is generally notified by the base station to the user through the DCI at the time of subframe n. Therefore, for the feedback signal s, the base station also needs to trigger in the DCI, and the time when the signal s is sent is n+m+k.

The candidate value of k can be configured by high-level signaling. Similar to m, the candidate value of k for different users can be different. For example, the base station informs user 1k that the candidate value of k is 0, 1...7 through high-level signaling, while the candidate value of user 2 are 0, 1, ... 3. Of course, even for the same user, different transmission areas can be separately configured with different candidate values of k by high-level signaling.

Figure 11 is a schematic diagram of the measurement feedback of the reference signal of the signal s1 on the subframe n1+m1 according to the embodiment. As shown in Figure 11, the signal s1 represents the measurement feedback of the reference signal on the subframe n1+m1, that is, the base station The feedback signal s1 is triggered in the control area of the frame n1, and s1 is the feedback of the measurement result of the reference signal on the subframe n1+m1, which is sent by the user in the subframe n1+m1+k1 and received by the base station. And s2 represents the user's measurement feedback on the reference signal sent on the subframe n2+m2. That is, the base station triggers the feedback signal s2 in the control area of subframe n2, and s2 is the feedback of the measurement result of the reference signal in subframe n2+m2, which is sent by the user in subframe n2+m2+k2 and received by the base station. If n1+m1+k1=n2+m2+k2, and the feedback resources overlap, merging or prioritization may be required.

Feedback of these measurement results may use uplink data channel feedback, and may also use uplink control channel for feedback. The overlapping of resources may only be overlapped in time units, and it is also fine if the frequency domain positions do not overlap. For example, the overlap of uplink data channels may refer to only the same time units. That is to say, the overlap or conflict of resource locations may be in one or more of the time domain, frequency domain, and code domain.

If the user feeds back the measurement results on the physical layer data channel, even if the time-frequency resources of s1 and s2 are in one subframe, the user can feed back both s1 and s2 to the base station at the same time. At this time, the base station will receive s1 and s2 in the same subframe. Of course, only the measurement results with higher priority may be fed back according to the order of priority.

If the user feeds back the measurement results on the uplink control channel of the physical layer, and the control channel resources used by s1 and s2 overlap or completely conflict, then only the measurement results with higher priority need to be fed back according to the order of priority.

The order of priorities may also be ordered according to the order of the subframes in which the triggered DCI is located. For example, as shown in Figure 11, the priority of signal s2 is higher than that of s1 because n2 is later than n1.

Of course, the priority may also be determined according to the order of the subframes in which the reference signals corresponding to s1 and s2 are sent. That is to say, the priority is determined according to the sequence of subframes n1+m1 and n2+m2. For example, the feedback signal corresponding to the later RS has a higher priority.

Optionally, similar to the priority ordering of reference signals, the priority order of measurement result feedback signals may also be determined according to the type, density, bandwidth length, and number of ports of the corresponding reference signal. For example, for uplink channel control feedback, if the transmission resource corresponding to the measurement result of the beam reference signal conflicts with the resource of the measurement result of the channel measurement reference signal, it can be defined that the measurement result of the beam measurement reference signal has a higher priority. Then the user will discard the feedback of channel measurement results with low priority when sending.

Similarly, if the signals s1 and s2 are uplink data channels, the user can judge the priority according to the sequence of n1 and n2. The user can only send uplink data with high priority in the corresponding subframe.

For the transmission of uplink data, optionally, the user does not want to receive multiple triggers, and the multiple triggers are for the transmission of uplink data in the same uplink subframe. Similarly, for the feedback of the measurement result, optionally, the user does not want to receive multiple triggers, and the multiple triggers are the feedback of the measurement result of the same uplink subframe. Especially for the feedback of measurement results of the same reference signal. For example, for channel measurement result feedback, the user does not want to receive multiple triggers fed back in the same uplink subframe (the DCIs of these multiple triggers can be in different subframes), that is to say, the user does not want n1+m1= n2+m2. Similarly, for the transmission or reception of the reference signal, the user does not want to receive multiple triggers, and the multiple triggers are the transmission or reception of the reference signal on the same subframe with overlapping resource positions. At this time, there is no need for priority sorting, and the implementation of the base station can be relied on to avoid resource location conflicts between s1 and s2.

If the signals s1 and s2 include one or more of the following signals, prioritize according to the content contained in the signals s1 and s2: uplink scheduling data, measurement result feedback corresponding to the channel measurement reference signal, and measurement result feedback corresponding to the beam reference signal , the measurement result feedback corresponding to the precoding measurement reference signal, and the ACK/NACK feedback corresponding to the downlink scheduling. For example, the priority of uplink data can be distinguished according to the contained content. For example, if the uplink data signal s1 includes the CSI feedback, but s2 does not, it may be determined that the priority of s1 is high regardless of the order of n1 and n2. That is to say, the sending priority of the uplink data including the CSI feedback is high.

If signals s1 and s2 include one or more of the following signals, all or both of s1 and s2 are received simultaneously

Part of the information: uplink scheduling data, measurement result feedback corresponding to the channel measurement reference signal, measurement result feedback corresponding to the beam reference signal, measurement result feedback corresponding to the precoding measurement reference signal, and ACK/NACK feedback corresponding to the downlink scheduling. For example, when sending on the uplink data channel, even if n1+m1=n2+m2, the user can send these signals at the same time.

Further, the method of this embodiment is specifically described below with specific examples:

Trigger scheduling of uplink data

Figure 12 is a schematic diagram of the base station using DCI to dynamically trigger the transmission of uplink data in subframe #n1 in this embodiment. As shown in Figure 12, the base station uses DCI to dynamically trigger the transmission of uplink data in subframe #n1. After the DCI is detected in #n1, uplink data s1 will be sent in subframe #n1+m1. The specific value of m1 can be detected in DCI. At the same time, the user detects the scheduling of uplink data s2 in the DCI of subframe #n2, and the time to send data is also #n1+m1, that is, n1+m1=n2+m2. That is, the resource locations of s1 and s2 overlap. Since a user may not support sending two independently scheduled uplink data at the same time, as long as the time domain units overlap, the resource position overlap mentioned in the present invention is satisfied.

According to the priority sorting method of the present invention, the sorting can be performed according to the sizes of n1 and n2, that is, the uplink data transmission priority of the later time domain unit where the DCI is located is higher. Therefore, the user only sends uplink data s2 at the time of subframe #n1+m1.

Optionally, the priority may be determined according to the contents contained in s1 and s2. For example, if the base station triggers the feedback of the reference signal measurement results at the same time when the uplink data is triggered at the time of subframe #n1, and schedules the user to send at the time of subframe #n1+m1, and then the uplink data scheduled at the time of subframe #n2 When the data is not triggered to report the measurement results, the priority of s1 is higher than that of s2.

Optionally, the base station may simultaneously receive all or part of the information of s1 and s2. As shown in FIG. 12 , if the uplink data scheduled by the base station on both subframe #n1 and subframe #n2 includes the measurement result feedback of a certain reference signal. At this time, the priority can be sorted according to the content first, that is, the priority of the measurement result feedback triggered on subframe #n1 and subframe #n2 is higher than that of data transmission, and then sorted according to the size of n1 and n2, that is, subframe# The priority of the uplink data content that triggers scheduling on subframe #n2 is higher than the uplink data content that triggers scheduling on subframe #n1, so in the end, the user can send the content triggered on subframe #n1 and subframe #n2 in the uplink data area of subframe #n2 Feedback of measurement results and uplink data triggered on subframe #n2. Therefore, in terms of priority sorting, it can be sorted according to the content contained in the signal first, such as whether the channel measurement result feedback is included, and then sorted according to the subframe where the DCI is triggered.

Optionally, the user does not want to receive multiple DCI-triggered uplink data scheduling in the same subframe.
