Description

Signal transmitting, receiving and transmitting device

Technical Field

The present invention relates to the field of communications, and in particular, to a signal transmitting apparatus, a signal receiving apparatus, a signal transmitting apparatus, a signal receiving apparatus, and a signal transmitting apparatus.

Background

In Long-Term Evolution (LTE), there are many periodic reference signals, such as synchronization signals, cell reference signals, channel measurement reference signals, uplink sounding reference signals, and the like, and a user may receive or send the periodic reference signals according to a period configured by a high-level signaling. The periodic reference signal configuration is simple, and only the base station needs to use semi-static configuration of high-level signaling without additional dynamic signaling notification. However, the periodic reference signal transmission may bring a large overhead to the system. Therefore, in LTE, some aperiodic reference signals, such as aperiodic sounding reference signals, are entered at the same time, and the base station may configure one or more sounding reference signal configurations by using higher layer signaling, where the configuration parameters include parameters such as transmission bandwidth, time-frequency position, and sequence cyclic shift, and the base station may determine whether to trigger the transmission of the sounding reference signal on the physical layer control area according to the requirement. This is the aperiodic sounding reference signal.

In 5G (new radio), since the data amount requirement of the user increases, in order to reduce the overhead, especially the overhead of the sounding reference signal, it is a trend to introduce the aperiodic reference signal. Such as aperiodic csi.

In addition, LTE does not require beam reference signals. This is because the LTE base station or user often uses a wide rf beam to achieve cell-level coverage when transmitting the reference signal. Fig. 1-a is a cell-level coverage of a radio frequency beam when transmitting a reference signal in the related art, as shown in fig. 1-a. Since the carrier frequency for LTE is basically 6GHz or less, a wide radio frequency beam formed by a multi-antenna array can cover the entire cell. In contrast, in 5G, not only the carrier band below 6GHz but also a band above 6GHz, for example, 60GHz, is supported. This presents a significant challenge to wireless communications because the large scale path loss is very large in the high frequency band. But since the center frequency is high in the high frequency band and the wavelength is short, the base station can accommodate a large number of antennas and form a narrow beam using a plurality of antennas to form a beamforming gain. Narrow rf beamforming is almost an indispensable technology for enhancing cell coverage in high frequency bands. And to configure the user with that beam, it may be necessary for the base station to transmit a beam reference signal for the user to measure the best beam. Fig. 1-b is a schematic diagram illustrating different beam directions corresponding to different reference signals in the related art, and as shown in fig. 1-b, a base station may trigger or periodically transmit beam reference signals, where the different reference signals correspond to different beam directions. The UE may feed back one or more optimal beam sequence numbers to the base station after measuring the beam reference signal, so that the base station may transmit data to a specific user using the optimal beam when subsequently transmitting data.

As mentioned above, the introduction of aperiodic beamformed reference signals also saves the pilot overhead of the system.

Furthermore, for beam measurement reference signals and other similar reference signals, the dynamically activated approach may also be introduced in 5G. For example, the base station may activate the beam reference signal transmission by using physical layer dynamic signaling, and after activation, the base station transmits a periodic or multiple beam reference signals according to the higher layer signaling configuration.

Fig. 2-a is a schematic diagram of triggering a downlink reference signal in the related art, and as shown in fig. 2-a, if the triggering is performed on the downlink reference signal, after the base station triggers a reference signal in a physical layer control region of a subframe n, the base station will transmit on a subframe n + m, and it is assumed that the subframe n + m is a downlink subframe. If the trigger is the uplink reference signal, after the base station triggers a reference signal on the physical layer control region of the subframe n, the user will send on a subframe n + m, wherein the subframe n + m includes an uplink sending region.

To support flexible subframe configuration, generally, the candidate value of m may be multiple, such as 0,1,2,3. The base station dynamically informs m of a specific value when triggering the reference signal. If m =0, the DCI triggering the reference signal and the transmitted reference signal are in one subframe.

Whether the UE needs to feed back the measurement results, and in which subframe the measurement results need to be fed back may also need to be included in the dynamic signaling. Generally, the base station may notify the user to feed back the measurement result to the base station k subframes after measuring the reference signal by using dynamic signaling. Fig. 2-b is a schematic diagram illustrating measurement result feedback in the related art, and as shown in fig. 2-b, after the base station triggers a certain downlink measurement reference signal in the physical layer control region of the subframe n, the base station will transmit the measurement result in the subframe n + m, and at the same time, the base station triggers measurement result feedback in the subframe n, so that the user will transmit the measurement result to the base station in the subframe n + m + k.

To support flexible subframe configuration, generally, the candidate value of k may be multiple, such as 0,1, 2.. 7. For example, if k =0 is a downlink subframe, the base station cannot configure k =0, because it is not possible for the user to transmit uplink data using the downlink subframe.

The dynamic trigger reference signal and the feedback bring great flexibility to the system and bring certain trouble to the system. As shown in fig. 2-a, the base station triggers reference signal 1 to be transmitted on subframe n +3 in subframe n, when m =3, and the base station triggers reference signal 2 to be transmitted on subframe n +3 in subframe n +1, when m =2. Thus, if the reference signal 1 and reference signal 2 resource positions overlap, the measurement and feedback of the user may be disturbed.

In view of the above problems in the related art, no effective solution has been found at present.

Optionally, when the signal s1 and the signal s2 include one or more of the following signals, the signals are prioritized according to the receiving time, or the type, or the density, or the bandwidth length, or the number of ports, of the reference signal corresponding to the signals s1 and s 2: and feeding back a measurement result corresponding to the channel measurement reference signal, feeding back a measurement result corresponding to the beam reference signal, and feeding back a measurement result corresponding to the precoding measurement reference signal.

Alternatively, signal s1 and signal s2 may be received or transmitted on overlapping resource locations according to the indicated priority rules.

Alternatively, the user does not wish to receive or transmit s1 and s2 on overlapping resource locations. At this time, the scheduling of the base station is relied on by default to avoid the resource positions of the signals s1 and s2 from overlapping, and when the time units n1 and n2 overlap on the resource positions, the base station does not trigger the corresponding signals s1 and s2 to transmit.

Example 3

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

the embodiment provides a method for triggering reference signals and sorting feedback priorities thereof, which comprises the following steps:

the sending end triggers the signal s1 to send or receive in the time unit n1, and

and the transmitting end triggers the signal s2 to transmit or receive at time unit n2+ m2 at time unit n 2. And if the resource positions of the signals s1 and s2 are overlapped, receiving or sending the signals s1 and s2 according to a certain priority rule.

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

The one time unit may be 1 subframe or a minimum scheduling time unit. The downlink transmitting end refers to a base station, the receiving end refers to a user terminal, the uplink transmitting end refers to a user, and the receiving end refers to a base station. Whether uplink or downlink, the triggering is done by the base station. For these reference signals, the base station may configure Resource positions, i.e., frequency positions, of the reference signals in one subframe by using higher layer signaling, such as which time domain Orthogonal Frequency Division Multiplexing (OFDM) symbols in one subframe, bandwidth length, such as the fraction of the system bandwidth of the reference symbols, density of the reference symbols, such as whether each Physical Resource Block (PRB) is transmitted, or once every two PRBs is transmitted, and so on. After the parameters are configured in the higher layer signaling, the base station may use a Downlink Control Information (DCI) bit to trigger whether to send a reference signal and which subframe to send in the following. Of course, the base station may configure multiple reference signal configuration parameters to the user through RRC signaling, and then the base station may trigger one of the parameters through the bit information of the DCI.

That is, the base station determines whether or not a certain reference signal is triggered and which subframe the reference signal is transmitted in, based on information included in the DCI. As shown in fig. 2-a, in subframe n, the base station triggers the downlink measurement reference signal with DCI, and then at the same time, some information bits are included in the DCI to tell the value of user m, and in subframe n + m, the base station will send the measurement reference signal. The time frequency position, bandwidth, density and other parameters of the measurement reference signal need to be known according to the high-level signaling indication.

Fig. 9 is a schematic diagram of the prioritization in this embodiment, and as shown in fig. 9, the transmission time unit n1 is the subframe n, and the transmission unit n2 is the subframe n +1, m1=3, and m2=2. The base station triggers the sounding reference signal s1 on subframe n1 and the sounding reference signal s2 on subframe n 2. s1 and s2 may be the same type of measurement Reference signal, for example, both are downlink Channel measurement Reference Signals (CSI-RS), and parameters such as bandwidth, density, and the like, configured to s1 and s2 by a high-level signaling may be the same or different. If the time-frequency positions of s1 and s2 overlap, the reference signals with low priority can be discarded according to the priority rule. That is, at this time, n1+ m1= n2+ m2, and the base station transmits only the reference signal with the highest priority, and discards the reference signal with the low priority.

Of course, s1 and s2 are the same type of reference signal, but the higher layer signaling configuration may be different. For example, for CSI-RS, the higher layer signaling configures multiple configurations, in subframe n1, DCI triggers one configuration parameter, and in subframe n2, DCI triggers another configuration parameter, but if the time-frequency positions of the reference signals indicated by the two configuration parameters overlap, 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 two types of reference signals configured by a higher layer overlap, only the reference signals with high priority need to be sent and the reference signals with low priority need to be discarded according to the priority order.

It should be noted that the present embodiment is not only applicable to two reference signal transmission collisions.

The predefined reference signal sorting method may be sorting according to the subframe sequence of the DCI trigger, for example, the reference signal priority of the DCI post-trigger is high, as shown in fig. 9, since the DCI trigger corresponding to s2 is in the subframe n2, and the subframe n2 is behind, the s2 has high priority. Therefore, the base station transmits only the sounding reference signal s2 at the time of the subframe n2+ m2 or n1+ m1. The sorting according to the method can completely arrange the priority according to the subframe sequence of the DCI without considering the type of the reference signal.

Alternatively, the user does not want the base station triggered reference signals to be transmitted or received on the same time cell. For example, for the downlink channel sounding reference signal and the beam reference signal, if resource locations of s1 and s2 overlap, the user does not want n2+ m2= n1+ m1.

The resource positions of the reference signals are overlapped, which means that in the same transmission time unit, the time domain symbol where the reference signal is located and the frequency domain resource positions are all overlapped or partially overlapped, as shown in fig. 9.

Alternatively, the predefined reference signal sorting method may be to prioritize the density 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 s2, then the priority of s1 is high, and if there is an overlap in their time-frequency positions, the trigger of s2 is disabled. That is to say that no s2 signal is actually transmitted at the time of sub-frame n2+ m2.

For the priority ordering method of multiple types of measurement reference signal triggering and multiple triggering overlapping of each measurement reference signal, optionally, if s1 and s2 are different types of reference signals, priority ordering may be performed according to the types of the signals s1 and s2, and then priority ordering may be performed according to the order of n1 and n 2. For example, the priority of the beam reference signal is higher than that of the channel sounding reference signal, if s1 is the beam sounding reference signal and s2 is the CSI-RS, then even if n2 is later, the priority of s1 is still higher than s2. Optionally, if s1 and s2 are different types of reference signals, priority is first performed according to the density, or bandwidth length, or port number, of the signals s1 and s2, or the order of the corresponding n1 and n 2. And then the signals s1 and s2 are prioritized according to the types.

The prioritization rules may be different for each user, requiring the base station to be configured to each user through higher layer signaling. For example, user 1 is ordered according to DCI trigger time, and does not distinguish between reference signal types. And the user 2 has high priority of the beam reference signal and low priority of the CSI-RS, and is firstly sorted according to the type of the reference signal and then sorted according to the order of the DCI triggering time.

For different transmission regions, fig. 10 is a schematic diagram of multiplexing the non-transmission regions in this embodiment, for example, fig. 10, two transmission regions are frequency-domain multiplexed on the system bandwidth, and the subcarrier intervals of the transmission region 1 and the transmission region 2 are different, so that the OFDM symbol length in each time domain is also different, resulting in different subframe lengths. The base station can thus configure the priority rules of the two transmission regions separately by higher layer signaling.

The candidate values of m1, m2 are configured by higher layer signaling, and the candidate values for different users m may be different. And m represents that the measurement reference signal is transmitted m subframes after the DCI triggering time. For example, a candidate value of 1,m is 0,1,2,3 for a user, and a value of 2,m is 0,1 for a user. Different candidate values of m can bring flexibility because different users have different processing capacities and different processing time delays. In addition, for the users with high delay requirement, the candidate value of m can be configured to be smaller, and for the users with low delay requirement, the candidate value of m can be configured to be larger to increase flexibility. Of course, even for the same user, the base station individually configures different m candidate values for different transmission areas through higher layer signaling. It is worth noting that the flexible m candidates may not be limited to the reference signal ordering method. That is, even if the system does not rank these reference signals, the flexible m candidate scheme may provide benefits to the system.

The signals s1 and s2 include feedback of channel sounding reference signal measurement results, feedback of beam reference signal measurement results, feedback of precoding channel sounding reference signal measurement results, and the like. The feedback of these measurement results can be transmitted on the uplink data channel or the uplink control channel, and the overlapping or collision of the corresponding resource positions are the collision of the uplink data channel and the collision of the uplink control channel, respectively.

After the base station triggers the measurement reference signal at the time of the subframe n, and informs the user that the measurement reference signal will be sent at the time of the subframe n + m, the user feeds back the measurement result to the base station at the time of the subframe n + m + k. And the value of k is also typically reported to the user by the base station through DCI at the time of subframe n. Therefore, for the feedback signal s, the base station needs to trigger in the DCI, and the time when the signal s is transmitted is n + m + k.

The candidate value for k may be configured by higher layer signaling, similar to m, and the candidate values for different users k may be different, e.g., the base station informs user 1k that the candidate value is 0,1 \ 82307 and user 2 that the candidate value is 0,1, \82303through higher layer signaling. Of course, even for the same user, different transmission regions can individually configure different candidate values of k using higher layer signaling.

Fig. 11 is a schematic diagram illustrating measurement feedback of a reference signal of a signal s1 on a subframe n1+ m1 according to an embodiment, where, as shown in fig. 11, the signal s1 represents measurement feedback of the reference signal on the subframe n1+ m1, that is, a base station triggers a feedback signal s1 on a control area of the subframe n1, and s1 is feedback of a measurement result of the reference signal on the subframe n1+ m1, and is transmitted by a user in the subframe n1+ m1+ k1 and received by the base station. And s2 represents the measurement feedback of the user for the reference signal sent on subframe n2+ m2. That is, the base station triggers a feedback signal s2 on the control region of subframe n2, and s2 is a feedback of the measurement result of the reference signal on subframe n2+ m2, and is transmitted by the user in subframe n2+ m2+ k2 and received by the base station. Merging or prioritization may be required if n1+ m1+ k1= n2+ m2+ k2 and there is overlap in the resources fed back.

The feedback of these measurement results may be performed by using an uplink data channel or an uplink control channel. The resource overlap may be only time unit overlap, while the frequency domain locations do not overlap, e.g. the overlap for the uplink data channels may mean that only the time units are the same. That is, the overlap or collision of resource locations may be one or more of the time domain, frequency domain, and code domain overlap.

If the user feeds back the measurement result on the physical layer data channel, the user can feed back both s1 and s2 to the base station even if the time-frequency resources of s1 and s2 are in one subframe. The timing station receives s1 and s2 in the same subframe. Of course, only the measurement results with high priority may be fed back in order of priority.

If the user feeds back the measurement result on the uplink control channel of the physical layer, and the positions of the control channel resources used by s1 and s2 are overlapped or completely conflict, only the measurement result with high priority needs to be fed back according to the priority order.

The order of priority may also be ordered according to the subframe order in which the triggered DCI is located. For example, as shown in FIG. 11, signal s2 has a higher priority than s1 because n2 is back relative to n 1.

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

Alternatively, similar to the priority ranking of the reference signals, the priority ranking of the measurement result feedback signals may also be determined according to the type, density, bandwidth length, number of ports, and the like of the corresponding reference signals. For example, for the feedback of uplink channel control, if the transmission resource of the measurement result corresponding to the beam reference signal conflicts with the resource of the measurement result of the channel measurement reference signal, it may be defined that the measurement result of the beam reference signal has a high priority. The user discards the feedback of the channel measurement result with low priority when transmitting.

Similarly, if the signals s1 and s2 are uplink data channels, the user can determine the priority according to the precedence order of n1 and n 2. The user can transmit only the uplink data with high priority in the corresponding sub-frame.

For the transmission of uplink data, optionally, the user does not want to receive multiple triggers, where the multiple triggers are the uplink data transmission of the same uplink subframe. Similarly, for the feedback of the measurement result, optionally, the user does not want to receive multiple triggers, which are the feedback of the measurement result of the same uplink subframe. Especially for measurement feedback of the same reference signal. For example, for channel measurement result feedback, a user does not want to receive multiple triggers fed back in the same uplink subframe (DCI of the multiple triggers may be in different subframes), that is, 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, which are the transmission or reception of the reference signal on the same subframe and with overlapping resource locations. In this case, priority ordering is not required, and resource location collision between s1 and s2 can be avoided depending on the implementation of the base station.

If the signals s1 and s2 include one or more of the following, the signals s1 and s2 are prioritized according to their content: the method comprises the steps of feeding back data of uplink scheduling, measurement results corresponding to channel measurement reference signals, measurement results corresponding to beam reference signals, measurement results corresponding to precoding measurement reference signals and ACK/NACK (acknowledgement/negative acknowledgement) feedback corresponding to downlink scheduling. For example, the priority of the upstream data can be differentiated according to the content contained. For example, if the uplink data signal s1 includes CSI feedback but s2 does not include CSI feedback, the priority of s1 may be determined without considering the sequence of n1 and n 2. That is, the uplink data including CSI feedback has a high transmission priority.

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

Person part information: the method comprises the steps of feeding back data of uplink scheduling, measurement results corresponding to channel measurement reference signals, measurement results corresponding to beam reference signals, measurement results corresponding to precoding measurement reference signals and ACK/NACK (acknowledgement/negative acknowledgement) feedback corresponding to downlink scheduling. For example, when transmitting on the uplink data channel, the users can transmit these signals simultaneously even if n1+ m1= n2+ m2.

Further, the method of the present embodiment is specifically described below with specific embodiments:

triggered scheduling of uplink data

Fig. 12 is a schematic diagram illustrating that the base station dynamically triggers transmission of uplink data by DCI in subframe # n1 according to the present embodiment, and as shown in fig. 12, the base station dynamically triggers transmission of uplink data by DCI in subframe # n1, and the user transmits uplink data s1 in subframe # n1+ m1 after detecting the DCI in subframe # n 1. The value of a particular m1 can be detected in DCI. Meanwhile, the user detects the scheduling of the uplink data s2 in the DCI of the subframe # n2, and the time when the data is transmitted is also # n1+ m1, that is, n1+ m1= n2+ m2. I.e. there is an overlap in resource locations of s1 and s2. Since one user may not support sending uplink data independently scheduled twice at the same time, the resource position overlap is satisfied as long as the time domain units overlap.

According to the priority sorting method provided by the invention, sorting can be carried out according to the sizes of n1 and n2, namely the uplink data transmission priority behind the time domain unit where the DCI is located is high. The user will only transmit uplink data s2 at time instant subframe # n1+ m1.

Alternatively, the priority may be determined according to the contents contained in s1 and s2. For example, if the base station triggers feedback of the reference signal measurement result at the same time when the base station triggers uplink data at the time of the subframe # n1, and schedules the user to transmit at the time of the subframe # n1+ m1, and does not trigger measurement result reporting when the uplink data is scheduled in the subframe # n2 later, the priority of s1 is higher than s2.

Alternatively, the base station may receive all or part of the information of s1 and s2 simultaneously. As shown in fig. 12, if the uplink data scheduled by the base station on both subframe # n1 and subframe # n2 includes measurement result feedback of a certain reference signal. Then, at this time, the feedback of the measurement results triggered on the subframe # n1 and the subframe # n2 and the uplink data triggered on the subframe # n2 can be prioritized according to the content, that is, the priority of the feedback of the measurement results triggered on the subframe # n1 and the subframe # n2 is higher than the data transmission, and then the sequencing is performed according to the sizes of n1 and n2, that is, the priority of the uplink data content triggered on the subframe # n2 is higher than the uplink data content triggered on the subframe # n1, so that finally, the user can transmit the feedback of the measurement results triggered on the subframe # n1 and the subframe # n2 and the uplink data triggered on the subframe # n2 in the uplink data region of the subframe # n 2. Therefore, in priority ordering, ordering may be performed according to the content included in the signal, for example, whether channel measurement result feedback is included, and then ordering may be performed according to the order of the subframes where the DCI triggers are located.

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

Optionally, in this embodiment, the storage medium may include, but is not limited to: a U-disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a removable hard disk, a magnetic disk, or an optical disk, and various media capable of storing program codes.
