In some embodiments, the network device may transmit a channel state information reference signal (Channel State Information Reference Signal, CSI-RS), the terminal may measure the CSI-RS to obtain channel state information, and transmit the channel state information to the network device, from which the network device may determine the channel state.

In some embodiments, the network device may send a channel state information reporting configuration (CSI report config) to the terminal, which may receive CSI-RS and/or send CSI report to the network device according to CSI report config.

In some embodiments, the network device may adjust the Spatial pattern (Spatial pattern) for some reasons. In some embodiments, adjusting the spatial format includes at least one of: adjusting the number of transmission resource units (Transmission Resource Units, txRU), adjusting the number of antenna units, wherein the antenna units may also be referred to as spatial elements (spatial elements).

For example, when the network device is in a network power saving (Network Energy Saving, NES) scenario, to reduce the power overhead of the network device, the number of spatial elements transmitted downstream may be dynamically reduced based on the dynamic change of the transmission load, so as to reduce the energy overhead of the network device.

In some embodiments, the network device adjusts the number of spatial elements of the downlink transmission in different manners, and may correspond to different downlink transmission types, e.g., the downlink transmission types include at least one of: measurement-first-adjustment (Measurement first then adaptation, MFTA), measurement-first-adjustment-last-measurement (Adaptation first then measurement, AFTM).

In some embodiments, CSI report config can include at least one sub-configuration (subsonfig). In some embodiments, different sub-configurations may correspond to different spatial adjustment (Spatial adaptation, SD) schemes (patterns), and/or different Power adjustment (PD) schemes.

For example, based on a plurality of sub-configurations, the terminal can measure the CSI-RS according to a plurality of SD patterns or PD patterns, thereby being beneficial to ensuring that CSI corresponding to a plurality of SD patterns and/or PD patterns can be obtained, so as to more comprehensively and accurately characterize channel states of different patterns, and being beneficial to further scheduling of subsequent data.

The following embodiments mainly use SD pattern to exemplarily illustrate the technical solutions of the present disclosure. In some embodiments, in embodiments involving SD patterns, SD patterns may be replaced with PD patterns, and in some embodiments, in embodiments involving SD patterns, SD patterns may be replaced with SD patterns and/or PD patterns.

For example, when the network device is in the NES mode, the network device can realize the energy saving effect by adjusting the spatial system. Taking the example that adjusting the spatial format includes reducing the number of txrus. Limited by the reduced number of txrus, the network device can only make downstream transmissions based on a partial SD pattern.

In some embodiments, the content of the downstream transmission includes at least one of: physical downlink control channel (physical downlink control channel, PDCCH), physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), CSI-RS, demodulation reference signal (Demodulation Reference Signal, DMRS).

Take downlink transmission including CSI-RS as an example. SD pattern can be configured through subsubonfig, on one hand, subsubonfig has an association relationship with SD pattern, on the other hand, the subsubonfig has an association relationship with individual CSI-RS resources (resources), and the CSI-RS resources can have an association relationship with the SD pattern associated with the associated subsubonfig. Since one CSI-RS resource may be associated with at least one subsubconfig, one CSI-RS resource may be associated with at least one SD pattern.

In some embodiments, the SD pattern and the number of antenna ports may be in one-to-one correspondence, for example, SD pattern #1 corresponds to a 32 antenna port and SD pattern #2 corresponds to a 16 antenna port.

In some embodiments, SD pattern corresponds to the number of antenna elements, e.g., for CSI-RS resource of 16 antenna ports, SD pattern #1 corresponds to 32 antenna elements, SD pattern #2 corresponds to 16 antenna elements.

In some embodiments, when the subsubonfig activates a certain SD pattern, the network device sends CSI-RS to the terminal based on the SD pattern on the subsubonfig-associated CSI-RS resource.

The terminal can determine the activated subsubonfig, namely the SD pattern associated with the sub-config is activated, and further can receive the CSI-RS sent by the network equipment at the CSI-RS resource associated with the activated subsubonfig based on the activated SD pattern.

However, there is a problem in that, when the network device is in the NES mode, CSI-RS can be transmitted based on only the partially activated SD pattern, limited by the reduced number of txrus. The terminal does not know that the network device can only send the CSI-RS based on the partially activated SD patterns due to the reduction of the TxRU number, so the terminal still receives the CSI-RS based on all the activated SD patterns, which can cause inaccurate CSI obtained by the terminal according to the CSI-RS and affect the accuracy of the CSI report.

The technical solutions of the present disclosure are exemplarily described below with reference to several drawings.

In MFTA mode, the network device may keep all txrus and/or antenna units activated (active) when transmitting CSI-RS, for example, since all txrus are activated, the network device may transmit CSI-RS to the terminal based on each SD pattern, for example, as shown in fig. 3A, the network device may transmit CSI-RS to the terminal based on SD pattern #1 (i.e., transmitting 32 ports of CSI-RS resource), and may transmit CSI-RS to the terminal based on SD pattern #2 (i.e., transmitting 16 ports of CSI-RS resource).

It should be noted that, in fig. 3A, although it is shown that the network device transmits CSI-RS based on one SD pattern (SD pattern #1 or SD pattern # 2) in one time domain unit, this is just one example, and since all txrus are active, the network device may transmit CSI-RS based on one or more SD patterns in any one time domain unit. Wherein the time domain unit comprises at least one of: frame, subframe, slot, symbol.

The terminal may receive CSI-RS sent by the base station based on different SD patterns (may also be referred to as TxRU patterns), and send CSI generated CSI report obtained by measuring the CSI-RS to the network device. For example, the terminal may obtain one CSI through CSI-RS transmitted based on multiple SD patterns and generate one CSI report to transmit to the network device, or the terminal may obtain multiple CSI through CSI-RS transmitted based on multiple SD patterns and generate multiple (multi) CSI reports to transmit to the network device.

But in MFTA mode, if the network device is in NES scenario, as many of the corresponding txrus may remain active when transmitting CSI-RS, while when transmitting PDSCH, part of the txrus may be turned off for energy saving reasons. The network device may alternately send CSI-RS and PDSCH, which may cause the network device to need to frequently turn on and off TxRU, that is, frequently switch TxRU patterns, which increases power overhead of the network device, and may cause a decrease in transmission performance due to switching time required for switching operation. Therefore, on the basis of MFTA, AFTM mode is introduced.

In AFTM mode, the network device may turn off part of the TxRU and/or the antenna element, keeping only part of the TxRU and/or the antenna element active. Taking the example of turning off the portion TxRU, the network device is limited to only send CSI-RS (i.e., transmitting 16-port CSI-RS resource) to the terminal based on SD pattern #2, but not send CSI-RS (i.e., transmitting 32-port CSI-RS resource) to the terminal based on SD pattern #1, which is limited to the portion TxRU being turned off.

For example, as shown in fig. 3B, the network device first transmits CSI-RS to the terminal based on SD pattern #1, i.e., indicates to the terminal that SD pattern #1 is active. Then the network device decides to close the part TxRU, which is limited by that only part TxRU is activated, then the network device can only send CSI-RS to the terminal based on SD pattern #2, and the terminal should measure the CSI corresponding to the 16-port CSI-RS accordingly (but the current terminal cannot realize the operation due to the following technical problems), so that the 16-port CSI report can be sent to the network device. After a period of scheduling delay (scheduling delay), the network device may continue to send CSI-RS to the terminal based on SD pattern # 2.

In the scenario shown in fig. 3B, in the AFTM mode, although the network device sends CSI-RS to the terminal based on SD pattern #1 and adjusts to send CSI-RS to the terminal based on SD pattern #2, the terminal does not know that the network device has turned off the part TxRU, and then can send CSI-RS to the terminal based on SD pattern #2 only, and for the terminal, SD pattern #1 is still in an active state, so the terminal still receives CSI-RS sent by the network device according to SD pattern # 1. As can be seen, the SD pattern understanding of the CSI-RS by the terminal and the network device is inconsistent, which may cause the CSI obtained by the terminal according to the CSI-RS to be inaccurate, and affect the accuracy of CSI report.

It should be noted that, fig. 3B is only an example of transmitting CSI-RS based on SD pattern by the network device in the AFTM mode, in which the network device is not limited to transmitting CSI-RS based on only one SD pattern to the terminal before turning off the portion TxRU, and is not limited to transmitting CSI-RS based on only one SD pattern to the terminal after turning off the portion TxRU.

For example, in some embodiments, the network device may send CSI-RS to the terminal based on SD pattern #1 and SD pattern #2 before turning off the portion TxRU, and send CSI-RS to the terminal based on SD pattern #2 only after turning off the portion TxRU.

In a first aspect, embodiments of the present disclosure provide a signal receiving method. Fig. 4 is a schematic flow chart diagram illustrating a signal receiving method according to an embodiment of the present disclosure. The signal receiving method shown in the present embodiment may be performed by a terminal.

As shown in fig. 4, the signal receiving method may include the steps of:

in step S401, according to the type of downlink transmission, determining a first SD pattern in at least one spatial adjustment pattern associated with a CSI-RS resource of a CSI reference signal;

in step S402, a CSI-RS is received according to the first SD pattern.

It should be noted that the embodiment shown in fig. 4 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

In some embodiments, one CSI-RS resource may be associated with at least one SD pattern. For example, the SD pattern may be configured by a subsubonfig, where the subsubonfig has an association relationship with the SD pattern on the one hand, and an association relationship with a CSI-RS resource (resource) on the other hand, and the CSI-RS resource may have an association relationship with the SD pattern associated with the associated subsubonfig. Since one CSI-RS resource may be associated with at least one subsubconfig, one CSI-RS resource may be associated with at least one SD pattern.

According to an embodiment of the present disclosure, the SD pattern on which the terminal receives the CSI-RS may not be fixed, but may be variable. Specifically, the terminal may determine the first SD pattern in at least one SD pattern associated with the CSI-RS resource according to the type of downlink transmission, and receive the CSI-RS according to the first SD pattern, that is, as the type of downlink transmission is different, the SD pattern on which the terminal receives the CSI-RS may also be different.

For example, when the type of downlink transmission is MFTA, the terminal may receive CSI-RS according to the activated SD pattern. Wherein, the activated SD pattern may refer to one or more SD patterns in which the network device indicates activation in at least one SD pattern through signaling.

For example, when the type of downlink transmission is AFTM, the network device may turn off the portion TxRU, which is limited by turning off the portion TxRU, and the network device may transmit CSI-RS based only on a portion of SD patterns among the plurality of SD patterns, with respect to the plurality of SD patterns activated before turning off the portion TxRU, and the terminal may not know that the network device may transmit CSI-RS based only on the portion of SD patterns. Therefore, the technical problem faced by the present application mainly exists in the case that the type of downlink transmission is AFTM, and the case that the type of downlink transmission is AFTM is described in the following by way of examples.

In some embodiments, the type of the downlink transmission is AFTM, and the terminal does not expect the channel state information configuration CSI report config to be different for SD patterns activated by the CSI-RS resource.

In some embodiments, the SD pattern associated with CSI-RS may be activated by CSI report config, and the terminal may not expect CSI report config to be different for the SD pattern activated by CSI-RS resources if it determines that the type of downlink transmission is AFTM, and may then determine CSI report config to activate only one SD pattern for CSI-RS resources.

For example, in the AFTM mode, the network device transmits CSI-RS to the terminal based on SD pattern #1 and SD pattern #2 before turning off the portion TxRU, and transmits CSI-RS to the terminal based on SD pattern #2 only after turning off the portion TxRU. When determining that the downlink transmission is in the AFTM mode, the terminal may not expect that the SD pattern activated by CSI report config for the CSI-RS resource is different, then it may only determine CSI report config that one SD pattern is activated for the CSI-RS resource, for example, the network device may instruct SD pattern #1 to deactivate, so that the terminal may determine CSI report config that only SD pattern #2 is activated for the CSI-RS resource, and further receive the CSI-RS sent by the network device based on SD pattern # 2. Accordingly, the SD pattern understanding consistency of the terminal and the network equipment to the CSI-RS can be ensured, and the accurate measurement of the terminal to the CSI-RS is ensured, so that accurate CSI is obtained.

As shown in fig. 5, 3 CSI-RS resources and 2 CSI report config are exemplified.

The 3 CSI-RS resources are CSI-RS resources #1, CSI-RS resources #2 and CSI-RS resources #3 respectively, wherein the CSI-RS resources #1 is associated with n1 SD pattern, the CSI-RS resources #1 to SD pattern #1 respectively, the CSI-RS resources #1 is associated with n2 SD pattern, the CSI-RS resources #1 to SD pattern #2 respectively, the CSI-RS resources #1 is associated with n3 SD pattern, and the CSI-RS resources #1 to SD pattern #3 respectively.

2 CSI report config are CSI report config #1 and CSI report config #2, respectively, wherein CSI report config #1 contains m1 SD patterns, subsubconfig#1 to SD patterns#m1, CSI report config #1 contains m2 SD patterns, subsubconfig#1 to SD patterns#m2, respectively.

The subsubonfig in CSI report config #1 is associated with the SD pattern associated with CSI-RS resource#1 and CSI-RS resource#2, and can be used to activate the SD pattern associated with CSI-RS resource#1 and CSI-RS resource#2. For example, subsubonfig#1 in CSI report config #1 is used to activate SD pattern#1,CSI report config#1 associated with CSI-RS resource#1 and subsubonfig#2 in SD pattern#1,CSI report config#1 associated with CSI-RS resource#2; the subsubconfig#1 in CSI report config #1 can also be used to activate the SD pattern#1 associated with CSI-RS resource#2.

The subsubonfig in CSI report config #2 is associated with the SD pattern associated with CSI-RS resource#2 and CSI-RS resource#3, and can be used to activate the SD pattern associated with CSI-RS resource#2 and CSI-RS resource#3. For example, subsubonfig#3 in CSI report config #2 is used to activate SD pattern#3,CSI report config#2 associated with CSI-RS resource#2 subsubonfig#4 in SD pattern#3,CSI report config#2 associated with CSI-RS resource#3 is used to activate SD pattern#4 associated with CSI-RS resource#3; the subsubconfig#3 in CSI report config #2 can also be used to activate SD pattern#3 associated with CSI-RS resource#3.

It can be seen that in the embodiment shown in fig. 5, a single CSI report config can activate multiple SD patterns for CSI-RS resources, e.g., subsubonfig. 1 in CSI report config #1 for activating subsubonfig. 2 in SD pattern #1,CSI report config#1 associated with CSI-RS resource#1 for activating SD pattern#2 associated with CSI-RS resource#2. The plurality CSI report config may activate a plurality of SD patterns for the CSI-RS resources, e.g., subsubonfig. 3 in CSI report config #2 for activating subsubonfig. 4 in SD pattern#3,CSI report config#2 associated with CSI-RS resource#2 for activating SD pattern#4 associated with CSI-RS resource#3.

In the case that the downlink transmission is in the AFTM mode, the downlink transmission is limited by turning off the part TxRU, and the network device can only send the CSI-RS based on the part SD pattern in the plurality of SD patterns, relative to the plurality of SD patterns activated before turning off the part TxRU, in this case, if the terminal still receives the CSI-RS based on the plurality of SD patterns, the terminal and the network device may not understand the SD pattern of the CSI-RS consistently, which affects the accuracy of CSI report.

In some embodiments, the terminal unexpected channel state information configuration CSI report config may include at least one of the following, different SD patterns for the CSI-RS resource activation:

the terminal does not expect that a single CSI report config is different for the SD pattern activated by the CSI-RS resource;

the terminal does not expect that the plurality CSI report config of SD patterns activated for the CSI-RS resource are different.

For example, the terminal may not expect CSI report config #1 to be different for the SD pattern activated by CSI-RS resource#1, specifically, the terminal may not expect any one of the subsubonfig. CSI report config #1 to be different for the SD pattern activated by CSI-RS resource#1, and then the terminal may determine that any one of the subsubonfig. CSI report config #1 activates only one SD pattern for CSI-RS resource#1. For example, activated subsubonfig in CSI report config #1 includes subsubonfig#1 and subsubonfig#2, wherein subsubonfig#1 activates SD pattern#1 for CSI-RS resource#1 and subsubonfig#2 activates SD pattern#2 for CSI-RS resource#1. Under the condition that the downlink transmission type is determined to be AFTM, the terminal can also only determine that the subsubconfig#1 and the subsubconfig#2 activate one SD pattern for the CSI-RS resource#1, for example, determine to activate the SD pattern#2, and then the terminal can receive the CSI-RS in the CSI-RS resource#1 according to the SD pattern#2.

Correspondingly, in the case that the downlink transmission is in the ATFM mode, the network device turns off part of the TxRU for energy saving, and can only transmit CSI-RS according to SD pattern #2. Accordingly, it can be ensured that the understanding of the network device and the terminal for the SD pattern is consistent, both being SD pattern #2.

For example, the terminal may not expect CSI report config #1 and CSI report config #2 to be different for the SD pattern activated by CSI-RS resource#1, and then the terminal may determine that only one SD pattern is activated by any one of the subsubonfig in CSI report config #1 and any one of the subsubonfig in CSI report config #2 for CSI-RS resource#1.

For example, activated subsubonfig in CSI report config #1 includes subsubonfig# 1,CSI report config#2 activated subsubonfig. includes subsubonfig. #3, wherein subsubonfig. #1 activates SD pattern#1 for CSI-RS resource#1 and subsubonfig. #3 activates SD pattern#3 for CSI-RS resource#1.

The network device may instruct the terminal to deactivate the subsurffig#3, and then the terminal may determine that only the subsurffig#1 is active, thereby determining that the SD pattern#1 configured by the subsurffig#1 is active, and further the terminal may receive the CSI-RS at the CSI-RS resource#1 according to the SD pattern#1.

Correspondingly, in the case that the downlink transmission is in the ATFM mode, the network device turns off part of the TxRU for energy saving, and can only transmit CSI-RS according to SD pattern #1. Accordingly, it can be ensured that the understanding of the network device and the terminal for the SD pattern is consistent, which is SD pattern #1.

It should be noted that, in the case that the downlink transmission is in the ATFM mode, the terminal may receive the CSI-RS based on one SD pattern as in the previous embodiment. However, embodiments of the present disclosure are not limited thereto, and in the case that the downlink transmission is an ATFM mode, the terminal may also receive CSI-RS based on multiple SD patterns, and in this case, the network device may also transmit CSI-RS based on multiple SD patterns. For example, the network device turns off a part of the TxRU, but can still send CSI-RS based on multiple SD patterns, so the terminal can also receive CSI-RS based on multiple SD patterns, which only needs to be consistent for the terminal and the network device to understand the multiple SD patterns.

In some embodiments, the terminal expects CSI report config that the SD pattern for CSI-RS resource activation is a specific SD pattern.

For example, a particular SD pattern includes at least one of: a specific number of SD patterns, a specific identified SD pattern, a most recent specific number of SD patterns.

Taking the example that a specific SD pattern includes a specific identification SD pattern, for example, a specific identification SD pattern includes an SD pattern #1 identified as 1 and an SD pattern #2 identified as 2.

In the case that the downlink transmission is in the ATFM mode, the terminal may expect the SD pattern activated for CSI-RS resources by CSI report config to be SD pattern #1 and SD pattern #2 identified as 2.

For example, the activated subsubonfig in CSI report config #1 includes subsubonfig#1, subsubonfig#2, and subsubonfig#3, wherein subsubonfig#1 activates SD pattern#1 for CSI-RS resource#1, subsubonfig#2 activates SD pattern#2 for CSI-RS resource#1, and subsubonfig#3 activates SD pattern#3 for CSI-RS resource#1.

The network device may instruct the terminal to deactivate the subsurffig#3, and then the terminal may determine that only subsurffig#1 and subsurffig#2 are active, thereby determining that SD pattern#1 configured by subsurffig#1 and SD pattern#2 configured by subsurffig#2 are active, and further the terminal may receive CSI-RS at CSI-RS resource#1 according to SD pattern#1 and SD pattern#2.

Correspondingly, in case of the downlink transmission being an ATFM mode, the network device turns off the partial TxRU for energy saving, and is still able to transmit the CSI-RS based on the SD pattern #1 and the SD pattern #2, although the CSI-RS cannot be transmitted based on the SD pattern #3. Accordingly, it can be ensured that the understanding of the network device and the terminal for the SD pattern is consistent, both being SD pattern #1 and SD pattern #2.

The downlink transmission type is AFTM, a plurality of SD patterns in the at least one SD pattern are in an active state, and the latest activated SD pattern (for example, the SD pattern corresponding to the latest activation signaling) is determined as the first SD pattern from the plurality of SD patterns in the active state.

For example, in the case where the terminal determines that the type of downlink transmission is AFTM, when a plurality of SD patterns in at least one SD pattern associated with CSI-RS resource are in an active state, the terminal may determine a last activated SD pattern among the plurality of SD patterns in the active state, and use the last activated SD pattern as the first SD pattern. Wherein, the activated SD pattern may refer to one or more SD patterns in which the network device indicates activation in at least one SD pattern through signaling.

For example, for CSI-RS resource #1, the SD pattern activated by CSI report config #1 for CSI-RS resource #1 includes SD pattern #1 and SD pattern #2, the terminal determines that SD pattern #1 is activated at time T1, SD pattern #2 is activated at time T2, and T2 is later than T1, so that SD pattern #2 can be determined as the last activated SD pattern, thereby determining SD pattern #2 as the first SD pattern, and further can receive CSI-RS at CSI-RS resource #1 according to SD pattern # 2.

and determining the SD pattern associated with the latest activated subsonic field as the first SD pattern in the plurality of subsonic fields in the activated state.

For example, if the terminal determines that the type of downlink transmission is AFTM, the terminal determines that a plurality of subsubonfig in CSI report config are in an active state, and the terminal may determine the latest activated subsubonfig in the plurality of subsubonfig in the active state, and use the SD pattern associated with the latest activated subsubonfig as the first SD pattern. Wherein, the activated subsubonfig may refer to one or more subsubonfig activated by the network device indicated in the plurality of subsubonfig in CSI report config by signaling.

For example, for CSI report config #1, activated subsubonfig in CSI report config #1 includes subsubonfig#1 and subsubonfig#2, wherein subsubonfig#1 correlates with SD pattern#1 in CSI-RS resource#1 and subsubonfig#2 correlates with SD pattern#2 in CSI-RS resource#1. The terminal determines that the subsubonfig#1 is activated at time T1, that the subsubonfig#2 is activated at time T2, and that T2 is later than T1, then it may be determined that the subsubonfig#2 is the latest activated SD pattern, thereby determining the SD pattern#2 associated with the subsubonfig#2 as the first SD pattern, and further may receive CSI-RS at CSI-RS resource#1 according to the SD pattern#2.

For example, the terminal may receive a first indication signaling sent by the network device when determining that the type of the downlink transmission is AFTM. The first indication signaling may be received before the terminal determines that the type of the downlink transmission is AFTM, or may be received after the terminal determines that the type of the downlink transmission is AFTM, which is not limited in this disclosure.

The first indication signaling may indicate one SD pattern (for example, an index (index) of the SD pattern may be indicated, or other information of the SD pattern) in at least one SD pattern associated with the CSI-RS resource, and the terminal may use the SD pattern indicated by the first indication signaling as the first SD pattern.

For example, for CSI-RS resource #1, CSI-RS resource #1 is associated with SD pattern #1 to SD pattern #1, and the terminal determines that the first indication signaling indicates SD pattern #2 in SD pattern #1 and SD pattern #1, so that SD pattern #2 may be determined to be the first SD pattern, and further CSI-RS may be received at CSI-RS resource #1 according to SD pattern # 2.

In some embodiments, the first indication signaling may also indicate the first SD pattern among a plurality of SD patterns in an active state of the at least one SD pattern.

For example, for CSI-RS resource #1, in SD pattern #1 and SD pattern #2 associated with CSI-RS resource #1 are in an active state, and the terminal determines that the first indication signaling indicates SD pattern #2 in SD pattern #1 and SD pattern #2, then it may be determined that SD pattern #2 is the first SD pattern, and further may receive CSI-RS at CSI-RS resource #1 according to SD pattern # 2.

In some embodiments, the first indication signaling includes at least one of:

cell-specific signaling;

radio resource control (Radio Resource Control, RRC) signaling;

downlink control information (Downlink Control Information, DCI);

a medium access control layer control unit (Media Access Control Control Element, MAC CE).

For example, the cell-specific signaling includes at least one of: system information block (System Information Block, SIB), paging message (paging). The SIB may be an existing SIB or a newly defined SIB.

In some embodiments, the first indication signaling is used to indicate at least one of:

Identification of CSI-RS resources;

identification of a CSI-RS resource set;

identification of SD pattern;

identification of channel state information reporting configuration CSI report config

CSI report config identification of subsubconfig.

Wherein the identification in the embodiments of the present disclosure may also be referred to as an index.

For example, the first indication signaling may indicate that the identifier of the CSI-RS resource is CSI-RS resource #1 and indicate that the identifier of the SD pattern is SD pattern #2, and the terminal may determine that SD pattern #2 in CSI-RS resource #1 is the first SD pattern according to this. Of course, the identifier of the CSI-RS resource indicated by the first indication signaling is not limited to one or more, and the identifier of the SD pattern indicated by the first indication signaling is not limited to one or more.

For example, the first indication signaling may indicate an identity of 1 of CSI report config, from which the terminal may determine CSI report config #1; and an identifier 2 for indicating the subsonic fig, wherein the terminal can determine the subsonic fig#2 according to the identifier, and CSI report config and subsonic fig corresponding to the identifier indicated by the first indication signaling can be CSI report config and subsonic fig used for determining activation by the terminal, and further the terminal can determine SD pattern associated with the subsonic fig. For CSI-RS resource #1, the terminal may determine that subsubconfig#2 in CSI report config #1 correlates with SD pattern#2 in CSI-RS resource #1 as the first SD pattern accordingly. Of course, the identifier indicated by the first indication signaling CSI report config is not limited to one or more, and the identifier of the subsubonfig indicated by the first indication signaling is not limited to one or more, so that the first SD pattern determined by the terminal may also be a plurality of SD patterns.

As shown in fig. 6A, taking an example that the first indication signaling includes MAC CE, the first indication signaling is used to indicate the identity of CSI-RS resources and the identity of SD pattern. The MAC CE may include bytes Oct 1 to Oct n+3.

Wherein Oct 1 contains function indication information a/D for indicating that the function of the position bit in the subsequent byte is for indicating activation, deactivation, serving Cell identification (Serving Cell ID) and bandwidth part identification (BWP (Bandwidth Part) ID).

In some embodiments, oct 2 contains an identification of an activation indication R, CSI-RS resource set, e.g., CSI-RS resource set #1, e.g., R is 1, which may indicate that CSI-RS resource set #1 is activated, R is 0, which may indicate that CSI-RS resource set #1 is deactivated. Oct3 to Oct n+3 contain the identity of the activated SD pattern of the SD patterns associated with CSI-RS resource set #1, e.g., one or more of SD patterns #1 to SD pattern # n. For example, the identification of SD pattern in Oct3 as SD pattern #2 may indicate that SD pattern #2 is active.

In some embodiments, oct 2 contains an identification of an activation indication R, CSI report config, e.g., CSI report config #1, e.g., R is 1, may indicate activation CSI report config #1, R is 0, may indicate deactivation CSI report config #1.Oct 3 to Oct n+3 contain an identification of activated ones of the CSI report config subsubonfig, for example one or more of subsubonfig #1 to subsubonfig # n. For example, the identifier of the subsubonfig in Oct3 is subsubonfig#2, which may indicate that subsubonfig#2 is activated, and the terminal may determine that the SD pattern (e.g., SD pattern#2) associated with subsubonfig#2 is activated.

Oct 2 contains an identification of an activation indication R, CSI-RS resource, e.g., CSI-RS resource #1, e.g., R is 1, which may indicate that CSI-RS resource #1 is activated, R is 0, which may indicate that CSI-RS resource #1 is deactivated.

Oct 3 to Oct n+3 contain an activation indication R and an identification of the SD pattern associated with CSI-RS resource #1, e.g. SD pattern #1 to SD pattern # n1. For example, R in Oct 3 is 1, which may indicate that SD pattern #1 in CSI-RS resource #1 is activated, R in Oct 3 is 0, which may indicate that SD pattern #1 in CSI-RS resource #1 is deactivated.

In some embodiments, the method further comprises: the type of downlink transmission is determined according to an explicit or implicit manner. The terminal may determine that the downlink transmission type is MFTA or AFTM according to an explicit manner, or may determine that the downlink transmission type is MFTA or AFTM according to an implicit manner.

The following exemplary descriptions of the display mode and the implicit mode are provided by several embodiments, respectively.

In some embodiments, determining the type of downlink transmission based on the explicit manner includes: and determining the type of the downlink transmission according to a second indication signaling sent by the network equipment.

For example, in the case of determining to close the portion TxRU, the network device may send a second indication signaling to the terminal, where the second indication signaling is used to indicate that the type of downlink transmission is AFTM or MFTA. The terminal may determine, according to the second indication signaling, that the type of downlink transmission after receiving the second signaling is AFTM or MFTA.

In some embodiments, determining the type of downlink transmission according to the implicit manner includes: and determining the type of the downlink transmission according to the port number of the downlink information sent by the network equipment.

In some embodiments, the determining the type of the downlink transmission according to the port number of the downlink information sent by the network device includes: the last time (for example, the reference point includes at least one of a terminal receiving downlink transmission, a terminal receiving configuration information of the downlink transmission, a terminal receiving system information, and a terminal receiving paging) the first port number of the downlink information sent by the network device is smaller than the second port number of the downlink information sent by the network device before the last time of sending the downlink information, and the type of the downlink transmission is determined to be AFTM.

For example, the terminal may receive the downlink information sent by the network device, and determine the port number of the downlink information, where the downlink information includes at least one of the following: PDCCH, PDSCH, CSI-RS, DMRS. Further, the first port number port#1 of the downlink information sent by the network device last time and the second port number port#2 of the downlink information sent by the network device last time before the downlink information is sent by the network device last time can be determined, and the port#1 and the port#2 are compared, when the port#1 is smaller than the port#2, the terminal can determine that the port number of the downlink information is reduced by the network device, and can generally determine that the network device enters a network access mode, so as to determine that the type of downlink transmission is AFTM.

In a second aspect, embodiments of the present disclosure provide a signaling method. Fig. 7 is a schematic flow chart diagram illustrating a signaling method according to an embodiment of the present disclosure. The signaling method shown in this embodiment may be performed by a network device.

As shown in fig. 7, the signal receiving method may include the steps of:

in step S701, according to the type of downlink transmission, determining a first SD pattern in at least one spatial adjustment pattern associated with a CSI-RS resource of a CSI reference signal;

In step S702, the CSI-RS is transmitted according to the first SD pattern.

It should be noted that the embodiment shown in fig. 7 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

According to embodiments of the present disclosure, the SD pattern on which the network device transmits CSI-RS may not be fixed, but may be variable. Specifically, the network device may determine a first SD pattern in at least one SD pattern associated with the CSI-RS resource according to the type of downlink transmission, and send the CSI-RS according to the first SD pattern, so as to meet the related needs of the downlink transmission type, such as the energy saving needs.

Correspondingly, the terminal may also determine a first SD pattern in at least one SD pattern associated with the CSI-RS resource according to the type of downlink transmission, and receive the CSI-RS according to the first SD pattern. Therefore, the SD pattern based on which the CSI-RS is received by the terminal is guaranteed to be identical to the SD pattern based on which the CSI-RS is sent by the network equipment, and the SD pattern understanding consistency of the terminal and the network equipment to the CSI-RS is guaranteed, so that the accurate measurement of the terminal to the CSI-RS is guaranteed, and accurate CSI is obtained.

For example, when the type of downlink transmission is AFTM, the network device may turn off the portion TxRU, which is limited by turning off the portion TxRU, and the network device may transmit CSI-RS based only on a portion of SD patterns among the plurality of SD patterns, with respect to the plurality of SD patterns activated before turning off the portion TxRU, and the terminal may not know that the network device may transmit CSI-RS based only on the portion of SD patterns.

In some embodiments, the downlink transmission is of the AFTM type, and the channel state information configures CSI report configuration to activate one SD pattern for the CSI-RS resource.

Correspondingly, in the case that the type of downlink transmission is AFTM, the terminal may not expect the SD pattern activated by CSI report config for CSI-RS resources to be different.

For example, in the AFTM mode, the network device transmits CSI-RS to the terminal based on SD pattern #1 and SD pattern #2 before turning off the portion TxRU, and transmits CSI-RS to the terminal based on SD pattern #2 only after turning off the portion TxRU.

When determining that the downlink transmission is in the AFTM mode, the terminal may not expect that the SD pattern activated by CSI report config for the CSI-RS resource is different, then it may only determine CSI report config that one SD pattern is activated for the CSI-RS resource, for example, the network device may instruct the SD pattern #1 to deactivate, then the CSI response config activates only one SD pattern #2 for the CSI-RS resource, so that the terminal may determine CSI report config that only SD pattern #2 is activated for the CSI-RS resource, and further receive the CSI-RS sent by the network device based on the SD pattern # 2. Accordingly, the SD pattern understanding consistency of the terminal and the network equipment to the CSI-RS can be ensured, and the accurate measurement of the terminal to the CSI-RS is ensured, so that accurate CSI is obtained.

In some embodiments, determining the first SD pattern in at least one spatial adjustment pattern associated with a CSI-RS resource of the channel state information reference signal according to the type of downlink transmission includes:

the downlink transmission type is AFTM, a plurality of SD patterns in at least one SD pattern are in an active state, and the latest activated SD pattern is determined as the first SD pattern in the plurality of SD patterns in the active state.

For example, in the case where the type of downlink transmission is AFTM, when a plurality of SD patterns in at least one SD pattern associated with CSI-RS resource are in an active state, the network device may determine a last activated SD pattern among the plurality of SD patterns in the active state, and use the last activated SD pattern as the first SD pattern. Wherein, the activated SD pattern may refer to one or more SD patterns in which the network device indicates activation in at least one SD pattern through signaling.

For example, for CSI-RS resource #1, the SD pattern activated by CSI report config #1 for CSI-RS resource #1 includes SD pattern #1 and SD pattern #2, the network device determines that SD pattern #1 is activated at time T1, SD pattern #2 is activated at time T2, and T2 is later than T1, so that SD pattern #2 can be determined as the last activated SD pattern, thereby determining SD pattern #2 as the first SD pattern, and further CSI-RS can be sent at CSI-RS resource #1 according to SD pattern # 2. Correspondingly, the terminal receives the CSI-RS at the CSI-RS resource #1 according to the SD pattern # 2.

In some embodiments, the signaling method further comprises: the downlink transmission type is AFTM, and a first indication signaling is sent to the terminal, wherein the first indication signaling is used for indicating the terminal to determine a first SD pattern in at least one SD pattern, and the first SD pattern is used for sending CSI-RS by the network equipment.

For example, the network device may send a first indication signaling to the terminal in case it determines that the type of the downlink transmission is AFTM. The first indication signaling may be sent before the network device determines that the type of the downlink transmission is AFTM, or may be sent after the network device determines that the type of the downlink transmission is AFTM, which is not limited in this disclosure.

The first indication signaling may indicate one SD pattern (for example, an index (index) of the SD pattern may be indicated, or other information of the SD pattern) in at least one SD pattern associated with the CSI-RS resource, where the first SD pattern is used for the network device to send the CSI-RS, so that the terminal may determine the first SD pattern, and may further receive the CSI-RS based on the first SD pattern.

For example, for CSI-RS resource #1, CSI-RS resource #1 associates SD pattern #1 to SD pattern #1, the first indication signaling indicates SD pattern #2 in SD pattern #1 and SD pattern #1, and then the terminal may determine SD pattern #2 as the first SD pattern, and may further receive CSI-RS at CSI-RS resource #1 according to SD pattern # 2.

For example, for CSI-RS resource #1, in SD pattern associated with CSI-RS resource #1, SD pattern #1 and SD pattern #2 are in an active state, and the first indication signaling indicates SD pattern #2 in SD pattern #1 and SD pattern #2, then the terminal may determine SD pattern #2 as the first SD pattern, and may further receive CSI-RS at CSI-RS resource #1 according to SD pattern # 2.

For example, the cell-specific signaling includes at least one of: system Information Block (SIB), paging message (paging). The SIB may be an existing SIB or a newly defined SIB.

In some embodiments, the first indication signaling is used to indicate at least one of: identification of CSI-RS resources; identification of SD pattern; an identification of the channel state information reporting configuration CSI report config; CSI report config identification of subsubconfig. Wherein the identification in the embodiments of the present disclosure may also be referred to as an index.
