Description

Method and device for transmitting indication information

Technical Field

The application belongs to the technical field of communication, and particularly relates to a method and equipment for transmitting indication information.

Background

The terminal may maintain constant power and continuous phase in the transmission process of multiple Physical Uplink Shared Channels (PUSCHs), so that when receiving the multiple PUSCHs, the network side device may obtain Channel information for other PUSCHs based on a DeModulation Reference Signal (DMRS) of one of the PUSCHs, and further perform joint Channel estimation using the DMRSs of the multiple PUSCHs to improve reception performance, which may be referred to as DMRS binding (bundling). The DMRS bundling is also applicable to multiple Physical Uplink Control Channel (PUCCH) transmission.

The DMRS bundling requires that a terminal keeps constant power and continuous phase within a certain time, does not generate any own behavior, and has higher requirements on the terminal, so that the time for the terminal to keep power consistency is not easy to overlong. If the terminal triggers (e.g., changes in transmit power) to destroy the state of constant power or continuous phase, the network-side device cannot know the situation of the terminal, and if the network-side device still performs joint channel estimation, performance loss will be caused.

The following describes in detail a transmission method and device of indication information provided by embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 2, an embodiment of the present application provides a method 200 for transmitting indication information, which may be performed by a terminal, in other words, by software or hardware installed in the terminal, and the method includes the following steps.

S202: the terminal sends first indication information, wherein the first indication information is used for indicating at least one of the following information: whether the terminal maintains phase continuity; whether the terminal keeps the transmission power constant; the terminal maintains phase continuity and/or transmit power constant for a first duration.

The embodiment may be performed in the process of sending the first transmission by the terminal, where the first transmission may be transmission of multiple Physical Uplink Shared Channels (PUSCHs), transmission of multiple Physical Uplink Control Channels (PUCCHs), or the like.

With respect to the first transmission described above, reference may be made to fig. 3, where the first transmission in fig. 3 comprises 4 transmission opportunities, each occupying the first 5 symbols of a slot.

In this embodiment, the first indication may be contained within the first transmission; alternatively, the first indication information may also be transmitted simultaneously with the first transmission. For example, the first transmission is a PUSCH transmission, and the first indication information may be contained within the PUSCH transmission; alternatively, the first indication information is included in a DeModulation Reference Signal (DMRS) associated with the PUSCH, and the DMRS is used for the network side device to demodulate the PUSCH.

In one example, the first indication information is used to instruct the terminal to keep the phase continuous and/or the power constant. For example, in the example shown in fig. 2, the terminal sends the first indication information when sending the first transmission of the time slot 2, that is, the phase of the first transmission of the time slot 1 and the phase of the first transmission of the time slot 2 are kept continuous and/or the power of the first transmission of the time slot 2 is kept constant, so that the network side device can perform joint channel estimation on the first transmissions of the first two time slots to improve the reception performance, which is beneficial to improving the coverage capability.

In another example, the first indication information is used to indicate a first duration for which the terminal maintains phase continuity and/or transmission power constant. For example, in the example shown in fig. 2, the terminal sends the first indication information when sending the first transmission of the timeslot 1, where the first indication information indicates the time length of the first duration and the start time, for example, the start time is the start time of the timeslot 1, and the time length is 4 timeslots, so that the network side device can perform joint channel estimation on the first transmissions of the 4 timeslots, so as to improve the reception performance, and be beneficial to improving the coverage capability.

In yet another example, the first indication information is used to indicate that the terminal is not phase continuous and/or power constant. For example, in the example shown in fig. 2, the terminal sends the first indication information when sending the first transmission of time slot 4, so that the network side device may default that the first transmissions of the first three time slots are sent with the terminal maintaining phase continuity and constant power, and the network side device may perform joint channel estimation on the first transmissions of the first three time slots to improve the reception performance, which is beneficial to improving the coverage capability.

In the transmission method of the indication information provided in the embodiment of the present application, the terminal may indicate at least one of the following to the network side device: and if the terminal keeps continuous phase and constant transmitting power, the terminal keeps the first duration of continuous phase and/or constant transmitting power, so that the network side equipment can carry out joint channel estimation according to the terminal indication to improve the receiving performance and be beneficial to the improvement of the coverage capability.

Optionally, the sending, by the terminal, the first indication information in the foregoing embodiment may include: the terminal sends a first transmission in a binding time window (or a bundle window, etc.), and sends first indication information when a first event occurs.

In this embodiment, the network side device may configure a binding time window for the terminal, and in the binding time window, if the terminal does not send the first indication information, the network side device may default that the terminal keeps phase continuity and power constant when sending the first transmission.

In this embodiment, the terminal sends the first transmission within the binding time window, and may send the first indication information if the occurrence of the first event is detected, and the first event may include at least one of the following 1) to 4).

1) A Physical Random Access Channel (PRACH) is transmitted between transmission units of the first transmission. The transmission unit may be a transmission opportunity of the first transmission. For example, referring to fig. 4, in the example shown in fig. 4, the terminal transmits PRACH in slot 3, so that the phase of the first transmission in slot 4 is discontinuous and/or the power of the first transmission is not constant as compared with the first transmission before slot 4, so that the terminal may transmit the first indication information when transmitting the first transmission in slot 4, and the first indication information may be used to indicate that the phase of the terminal is discontinuous and/or the power of the terminal is not constant.

2) The transmission power of the terminal changes. In this example, the first indication information may be used to indicate that the power of the terminal is not constant.

3) The precoding for the first transmission changes. In this example, since the phase discontinuity and/or the power discontinuity of the terminal may be caused by a change from the code, the first indication information may be used to indicate that the phase discontinuity and/or the power discontinuity of the terminal is not constant.

4) A second transmission is sent that overlaps with a time domain resource occupied by the first transmission. In this example, since the second transmission is transmitted at the same time as the first transmission, phase discontinuity and/or power non-constancy of the terminal may be caused, and thus, the first indication information may be used to indicate that the phase discontinuity and/or power non-constancy of the terminal.

Alternatively, the aforementioned second transmission may include one of the following 1) to 4).

1) And configuring the authorized PUSCH, namely the Configured grant PUSCH.

2) The PRACH triggered by the terminal may be the terminal executing the method embodiment, or may be another terminal.

3) Scheduling Request (SR) on PUCCH, i.e. SR on PUCCH.

4) Uplink transmission on the second cell; wherein the first transmission is transmitted on a first cell. In this example, the first cell and the second cell may be the same; alternatively, the first cell and its second cell may be different. In a specific example, the embodiment may be applied in a Dual-Connectivity (DC) scenario, where the first cell and the second cell are different cell groups.

It was mentioned in the previous embodiments that the terminal sends the first transmission within the binding time window and, in case of a first event, sends the first indication information. Optionally, after the first event occurs, the foregoing embodiments may further include one of the following steps 1) and 2):

1) And the terminal does not perform transmission for keeping the phase continuity and/or the power constant within the binding time window. In this example, the terminal sends the first transmission within the bundling time window, and if the first event occurs, the subsequent first transmission may not need to maintain phase continuity nor power constant.

2) Adjusting the transmission power such that the phase of the terminal after the first time unit is kept continuous with the phase before the first time unit, and/or the power of the terminal after the first time unit is kept constant (or equal) with the power before the first time unit; wherein the first event causes phase discontinuity and/or power non-constant of the terminal within a first time unit. In this example, the first time unit may be a time slot.

Optionally, the sending of the first indication information mentioned in the foregoing embodiments includes one of the following 1) and 2).

1) Sending the first transmission, the first transmission including the first indication information; wherein the content indicated by the first indication information is opposite to the content indicated by second indication information, the second indication information being indication information included in the first transmission after the first time unit; wherein the first event causes phase discontinuity and/or power non-constant of the terminal within the first time unit.

This example mentions that the content indicated by the first indication information is opposite to the content indicated by the second indication information. For example, the first indication information indicates that the terminal is discontinuous in phase, and the second indication information indicates that the terminal is continuous in phase, where the phase is continuous in phase of the first transmission after the first time unit, and the phase of the first transmission before the first time unit is continuous, and the following is similar; for another example, the first indication information indicates that the power of the terminal is not constant, and the second indication information indicates that the power of the terminal is constant; for example, the first indication information indicates that the terminal is discontinuous in phase or not constant in power, and the second indication information indicates that the terminal is continuous in phase and constant in power.

This example may send 1bit marker information from the affected time unit of the first transmission, put into the first transmission for transmission. The unaffected part and the affected part are marked oppositely, so that the network side equipment can be distinguished conveniently.

2) Transmitting a DMRS associated with the first transmission, the DMRS including the first indication information; wherein the content indicated by the first indication information is opposite to the content indicated by second indication information, the second indication information being indication information included in the DMRS after the first time unit; wherein the first event causes phase discontinuity and/or power non-constancy of the terminal within the first time unit.

This example may send 1bit flag information from the affected time unit of the first transmission, and integrate the information into the DMRS for transmission. The unaffected part and the affected part are marked oppositely, so that the network side equipment can be distinguished conveniently.

In the embodiment, the network side device can fully perform joint channel estimation on the part capable of performing joint channel estimation through the first indication information and the second indication information, which is beneficial to improving the transmission performance.

In the foregoing embodiment, the first indication information included in the DMRS, and/or the second indication information included in the DMRS includes one of:

1) Orthogonal Cover Code (OCC) sequences. This example may multiplex OCC sequences into DMRS sequences, with different OCC sequences indicating different marker information.

The different mark information mentioned here may be the above-mentioned first indication information and second indication information, and the content indicated by the first indication information is opposite to the content indicated by the second indication information, and the following is the same.

2) A pair of phase rotation (phase rotation) sequences. This example may multiplex pairs of phase-rotated sequences into DMRS sequences, with different pairs of phase-rotated sequences indicating different marker information. The DMRS in this example is at least 2 columns.

3) DMRS time domain location. This example indicates different flag information by different DMRS positions.

4) DMRS time domain density (or time domain pattern). This example indicates different signature information by different DMRS time domain densities (time domain patterns).

5) Scrambling information of the DMRS sequence. This example indicates different tag information by scrambling different Identifications (IDs) or scrambling different sequences.

6) A cyclic prefix or root sequence of the DMRS sequence is generated. In this example different flag information is indicated by different cyclic prefixes or root sequences.

In the above embodiment, after the terminal sends the first indication information, the method further includes one of:

1) The terminal continues to maintain phase continuous and/or power constant transmission until the end of the bundling time window.

2) The terminal continues to maintain phase continuous and/or power constant transmission until the first event occurs again. It is understood that the specific content of the reoccurring first event and the previously occurred first event may be different, for example, the previously occurred first event is that the PRACH is transmitted by the terminal, and the reoccurring first event may be that the transmission power of the terminal is changed.

3) And the terminal does not perform transmission for keeping the phase continuity and/or the power constant within the binding time window.

Optionally, the above embodiment may further include the following steps: the terminal determines a multiplexing method for multiplexing the position of the DMRS and/or the first indication information to the DMRS according to at least one of the following 1) and 2).

1) The information is preconfigured. In this example, the network side device may indicate the location of the DMRS through the pre-configuration information, and/or indicate a multiplexing method for multiplexing the first indication information to the DMRS.

2) A number of time domain resources occupied by a transmission opportunity of the first transmission. E.g., by the total number of symbols of the transmission opportunity of the first transmission. For example, the total number of symbols of the transmission opportunity of the first transmission is 5, and the OCC sequence is used as the first indication information and the second indication information; the total number of symbols of the transmission opportunity of the first transmission is 4, a pair of phase rotation sequences is taken as the first indication information and the second indication information, and so on.

In order to describe the transmission method of the indication information provided in the embodiments of the present application in detail, the following description will be made with reference to several specific embodiments.

Example one

As shown in fig. 4, the first transmission is indicated by a symbol filled with oblique lines, and at the position of the time slot 3, the terminal triggers PRACH transmission, and although there is no time domain collision on the time slot of the first transmission, the terminal will affect the change of the transmission power of the first transmission, so that the phase after PRACH transmission cannot be consistent with that before PRACH transmission.

Therefore, the terminal may transmit first indication information indicating that the terminal is phase discontinuous when transmitting the first transmission of slot 4. Thus, the network side device can perform joint channel estimation on the first transmission of the first 3 time slots in the binding time window, and perform independent channel estimation on the first transmission of the time slot 4.

Second embodiment

As shown in fig. 5, the first transmission is represented by a symbol filled with oblique lines, and during the transmission of the first transmission, due to different path loss or obstruction, the transmission power or precoding of the first transmission changes, so that the phase cannot be kept consistent.

Thus, the terminal may transmit first indication information indicating that the terminal is phase discontinuous when transmitting the first transmission of slot 4. Thus, the network side device can perform joint channel estimation on the first transmission of the first 3 time slots in the binding time window, and perform independent channel estimation on the first transmission of the time slot 4.

Third embodiment

As shown in fig. 6, if the first transmission and the second transmission are performed in the serving cell 1, and the second transmission and the first transmission are overlapped in some time slots, in this case, the multiplexing problem of 2 transmissions is required, and it cannot be guaranteed that the power of the first transmission is consistent with that of the previous transmission, so that the phase-consistent transmission cannot be guaranteed any more.

Accordingly, the terminal may transmit first indication information indicating that the terminal is phase discontinuous when transmitting the first transmission of slot 3. In this way, the network side device may perform joint channel estimation on the first transmission of the first 2 time slots within the bonding time window, and perform independent channel estimation on the first transmissions of time slots 3 and 4.

As shown in fig. 7, if the first transmission and the second transmission are from different cells, the transmission power of the first transmission will also change, and phase-consistent transmission cannot be guaranteed.

Accordingly, the terminal may transmit first indication information indicating that the terminal is phase discontinuous when transmitting the first transmission of slot 3. Thus, the network side device can perform joint channel estimation on the first transmission of the first 2 time slots in the bonding time window, and perform independent channel estimation on the first transmissions of the time slots 3 and 4.

Example four

As shown in fig. 8, the symbols filled with diagonal lines indicate that the first indication information with 1bit is inserted into the first transmission at this time. When the first indication information is inserted into the first transmission, rate matching (rate matching) may be directly performed on the first transmission, or a part (original information of the first transmission) where the first indication information is inserted may be replaced.

In this embodiment, a corresponding flag transmission (corresponding to the first indication information in the foregoing embodiment, and the following similar) is performed in the affected time slot (time slot 3), which indicates that the phase of the terminal is discontinuous and/or the power is not constant, and a flag transmission (corresponding to the second indication information in the foregoing embodiment, and the following similar) is performed in the opposite time slot (time slot 4 and time slot 5) where the effect is ended, which indicates that the phase is continuous and/or the power is constant.

Thus, the network side device can perform joint channel estimation on the first transmissions of the time slots 1,2,4,5 in the binding time window; or, the network side device performs joint channel estimation on the first transmissions of the time slots 1 and 2 in the binding time window, and performs joint channel estimation on the first transmissions of the time slots 4 and 5 in the binding time window.

EXAMPLE five

As shown in fig. 9, the symbols filled with oblique lines indicate that the first indication information with 1bit is inserted into the DMRS for the first transmission at this time. After the power or the phase is influenced, multiplying a group of OCC sequences into the DMRS sequences in a frequency domain multiplication mode, wherein the position of a time slot 3 is shown; after the influence is over, another group of sequences with different phases from the original OCC are multiplied into the DMRS sequence in a frequency domain multiplication manner, referring to the positions of time slot 4 and time slot 5 in fig. 9, to show the labels in opposite directions.

Thus, the network side device can perform joint channel estimation on the first transmissions of the time slots 1,2,4,5 within the binding time window; or, the network side device performs joint channel estimation on the first transmissions of the time slots 1 and 2 in the binding time window, and performs joint channel estimation on the first transmissions of the time slots 4 and 5 in the binding time window.

Example six

As shown in fig. 10, the padded symbols represent the DMRS of the first transmission, and after being affected, a set of phase pairs or time domain OCCs are multiplied in the sequence in a time domain. Since the phase pair needs to identify the mark information by the front and back phase differences, at least 2 sets of DMRS sequences are needed to completely represent the front and back opposite marks.

EXAMPLE seven

As shown in fig. 11, the filled symbols represent the DMRS transmitted in the first transmission, and after the filled symbols are affected, the location of the filled symbols will change, and the network device knows the meaning of the change of the location of the DMRS through some preconfigured information, so that the network device can determine the implicit indication; after the impact is over, the original DMRS position is changed back.

Example eight

As shown in fig. 12, a padded symbol represents a DMRS for a first transmission, and after the DMRS is affected, the density (pattern) of the DMRS changes, and a network side device knows the meaning of the DMRS density (pattern) change through some preconfigured information, so that the implicit indication can be determined; after the influence is over, the original DMRS density (pattern) is changed back.

Example nine

As shown in fig. 13, the padded symbols represent the DMRS of the first transmission, and after being affected, the resulting root sequence, cyclic prefix, may be changed or different scrambled to generate different sequences; the network side device will judge what meaning mark is at this time according to the detection result. After the influence is over, the original generation mode can be restored.

Example ten

As shown in fig. 14, after the network side device analyzes the terminal mark information, the mark information shown in fig. 14, that is, mark 1 and mark 2, is obtained, at this time, if the middle time slot interval is small, so that the phase can be estimated by the network side device or other manners, and the phases before and after the time slot interval are continuous, the network side device may select all time slots with the same mark to perform joint channel estimation.

For example, the affected slot 6 in fig. 14 has a short affected time, so that the network side device can obtain the phase change value by means of phase estimation compensation or the like and compensate back, and then the slots 4,5, and 7 can perform joint channel estimation.

EXAMPLE eleven

As shown in fig. 14, after the network side device analyzes the terminal tag information, tag information shown in fig. 14, i.e., tag 1 and tag 2, is obtained. At this time, the network side device may select consecutive slots with the same label for joint channel estimation, for example, slots 4 and 5 for joint channel estimation. Slots 2,3 are affected slots and therefore joint channel estimation may not be performed.

Example twelve

As shown in fig. 15, after analyzing the terminal tag information, the network side device obtains tag information shown in fig. 15, i.e., tag 1 and tag 2. At this time, the network side device may select a part of the units with the same label to perform joint channel estimation, for example, a part of the time slot 4 and a part of the time slot 5 in the above figure to perform joint channel estimation.

The transmission method of the indication information according to the embodiment of the present application is described in detail above with reference to fig. 2 to 15. A transmission method of indication information according to another embodiment of the present application will be described in detail below with reference to fig. 16. It is to be understood that the interaction between the network side device and the terminal described from the network side device is the same as that described at the terminal side in the method shown in fig. 2, and the related description is appropriately omitted to avoid redundancy.
