[0002] In a communication system, a smart repeater can be a key device for a base station to expand the coverage of a small cell. Specifically, the smart repeater can amplify and forward the signal sent by a user equipment (UE) to the base station, and can amplify and forward the signal sent by the base station to the UE. In addition, the smart repeater can also directly communicate with the base station.

[0003] Therefore, in the related art, when the smart repeater communicates with the base station, there are two types of uplink signals, which are the signal of the UE forwarded by the smart repeater and the uplink signal generated by the smart repeater itself (i.e., the signal of the direct communication between the smart repeater and the base station); and there are also two types of downlink signals, which are the downlink signal of the base station that needs to be forwarded by the smart repeater and the downlink signal sent by the base station to the smart repeater for control (i.e., the signal of the direct communication between the smart repeater and the base station).

Depending on the context, the words "if" and "when" as used herein can be interpreted to mean "upon" or "when... then" or "in response to determining".

[0054] The signal multiplexing method / apparatus / device and storage medium provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0055] Figure 1 A flowchart of a signal multiplexing method provided by an embodiment of the present disclosure is shown in FIG. 14, which is applied to a relay device, as shown in FIG. 15, the signal multiplexing method can include the following steps: Figure 1

[0056] Step 101, determining corresponding transceiving resources of the first signal and the second signal.

[0057] ​In an embodiment of the present disclosure, the relay device can be a smart repeater, or any network device capable of directional signal amplification, or a terminal device with directional signal amplification function, which can be referred to as a "network-controlled relay device", a "relay device capable of directional signal amplification", a "smart relay device", a "network-assisted relay device", a "controllable relay device", and the like. Hereinafter, the "smart relay device" is used as a substitute.

[0058] A reconfigurable intelligent surface (RIS) is also known as a "reconfigurable intelligent surface" or "intelligent reflective surface". From the outside, the RIS is a plain sheet. However, it can be flexibly deployed in a wireless communication propagation environment and can manipulate the frequency, phase, polarization, and other characteristics of reflected or refracted electromagnetic waves to reshape the wireless channel. Specifically, the RIS can reflect the signals incident on its surface to a specific direction through precoding technology, thereby enhancing the signal strength at the receiving end and achieving channel control.

[0059] Since the smart relay device and the RIS have similar characteristics when interacting with the network, in the present disclosure, the smart relay device refers to the smart relay device and the RIS.

[0060] In an embodiment of the present disclosure, the first signal can be an uplink signal forwarded by the relay device and / or a downlink signal forwarded by the relay device; and the second signal can be an uplink signal (such as an uplink signal generated by the relay device itself, or a feedback signal of information sent by the base station to the relay device, etc.) and / or a downlink signal (such as a downlink signal sent by the base station to the relay device for control) directly interacted between the relay device and the base station.

[0061] In an embodiment of the present disclosure, the transceiving resource can be a transceiving resource corresponding to a multiplexing manner adopted by the relay device, where the multiplexing manner can include a time division multiplexing (TDM) manner, a frequency division multiplexing (FDM) manner, and a spatial division multiplexing (SDM) manner.

[0062] Further, in an embodiment of the present disclosure, the above-mentioned transceiving resource is specifically resource information used by the relay device when transceiving the first signal and the second signal. Wherein, when the multiplexing manner used by the relay device is different, the transceiving resource will also be different. Specifically, when the multiplexing manner is TDM, the transceiving resource can be time domain information of transceiving the first signal and / or time domain information of transceiving the second signal; when the multiplexing manner is FDM, the transceiving resource can be frequency domain information of transceiving the first signal and / or frequency domain information of transceiving the second signal; when the multiplexing manner is SDM, the transceiving resource can be beam information or polarization direction information or antenna port information of transceiving the first signal and / or beam information or polarization direction information or antenna port information of transceiving the second signal. Wherein, in an embodiment of the present disclosure, the transceiving resource corresponding to the first signal is different from the transceiving resource corresponding to the second signal at the same time.

[0063] In addition, the above-mentioned "determining the multiplexing manner of the first signal and the second signal and the transceiving resource corresponding to the multiplexing manner" can include multiple aspects, and the content related to this aspect will be described in detail in subsequent embodiments.

[0064] Step 102, transceiving the first signal and the second signal based on the transceiving resource of the first signal and the second signal respectively.

[0065] Specifically, in an embodiment of the present disclosure, the first signal can be transceived based on the transceiving resource corresponding to the first signal, and the second signal can be transceived based on the transceiving resource corresponding to the second signal, so as to realize the separate transceiving of the first signal and the second signal.

[0066] In summary, in the signal multiplexing method provided by the embodiment of the present disclosure, the relay device determines the multiplexing manner of the first signal and the second signal and the transceiving resource corresponding to the multiplexing manner, wherein the first signal can be the uplink signal forwarded by the relay device and / or the downlink signal forwarded by the relay device, and the second signal can be the uplink signal and / or the downlink signal directly interacted between the relay device and the base station. Then, the relay device transceives the first signal and the second signal based on the multiplexing manner and the transceiving resource of the first signal and the second signal. Thus, in an embodiment of the present disclosure, a signal multiplexing method is provided, which can distinguish the first signal forwarded by the relay device and the second signal directly interacted between the relay device and the base station, and transceive the two types of signals separately.

Therefore, in one embodiment of the present disclosure, a signal multiplexing method is provided, which can distinguish the first signal relayed by the relay device and the second signal directly interacted between the relay device and the base station, and will separately transceive the two types of signals.

[0072] Figure 3a A flowchart of a signal multiplexing method provided by an embodiment of the present disclosure is applied to a relay device, as shown in the figure, the signal multiplexing method can include the following steps: Figure 3a

[0073] Step 301a, obtaining the multiplexing manner of the first signal and the second signal sent by the base station.

[0074] Wherein, in one embodiment of the present disclosure, the obtaining of the corresponding transceiving resource of the first signal and the second signal sent by the base station can include:

[0075] Obtaining the multiplexing manner of the first signal and the second signal sent by the base station through the RRC (Ratio Resource Control, Radio Resource Control) message.

[0076] It should be noted that in one embodiment of the present disclosure, after the base station sends the multiplexing manner of the first signal and the second signal to the relay device through the RRC message, it can also update and send the multiplexing manner of the first signal and the second signal to the relay device subsequently.

[0077] Step 302a, determining the corresponding transceiving resource of the first signal and the second signal based on a protocol agreement.

[0078] ​In an embodiment of the present disclosure, when the relay device determines the multiplexing mode by acquiring the multiplexing mode of the first signal and the second signal sent by the base station, the relay device can directly determine the corresponding transceiving resources of the first signal and the second signal based on the protocol agreement.

[0079] In the embodiment of the present disclosure, the detailed description of the first signal, the second signal, the multiplexing mode, and the corresponding transceiving resources of the multiplexing mode can refer to the description of the above-mentioned embodiments, and the present disclosure will not be repeated here.

[0081] In summary, in the signal multiplexing method provided by the embodiment of the present disclosure, the relay device determines the multiplexing mode of the first signal and the second signal and the corresponding transceiving resources of the multiplexing mode, wherein the first signal can be the relayed uplink signal and / or the relayed downlink signal of the relay device, and the second signal can be the uplink signal and / or the downlink signal directly interacted between the relay device and the base station, and then the relay device transceives the first signal and the second signal based on the multiplexing mode and the corresponding transceiving resources of the first signal and the second signal. Therefore, in an embodiment of the present disclosure, a signal multiplexing method is provided, which can distinguish the first signal relayed by the relay device and the second signal directly interacted between the relay device and the base station, and transceive the two types of signals separately.

[0082] Figure 3b A flowchart of a signal multiplexing method provided by an embodiment of the present disclosure is applied to a relay device, as shown in Figure 3b The signal multiplexing method can include the following steps:

[0086] In one embodiment of the present disclosure, the relay device can determine the transceiving resource based on the RRC indication of the base station (e.g., RRC semi-static configuration). In another embodiment of the present disclosure, the relay device can determine the transceiving resource based on the MAC-CE (Media Access Control-Control Element) indication of the base station (e.g., MAC-CE dynamic activation) on the basis of the RRC configuration. In yet another embodiment of the present disclosure, the relay device can determine the transceiving resource based on the DCI (Downlink Control Information) indication of the base station (e.g., DCI dynamic indication) on the basis of the RRC configuration.

[0088] Step 303b: transceiving the first signal and the second signal based on the multiplexing manner and the transceiving resource of the first signal and the second signal.

[0089] In summary, in the signal multiplexing method provided by the embodiments of the present disclosure, the relay device determines the multiplexing manner of the first signal and the second signal and the transceiving resource corresponding to the multiplexing manner, wherein the first signal can be the relayed uplink signal and / or the relayed downlink signal of the relay device, and the second signal can be the uplink signal and / or the downlink signal directly interacted between the relay device and the base station. Then, the relay device transceives the first signal and the second signal based on the multiplexing manner and the transceiving resource of the first signal and the second signal. Thus, in one embodiment of the present disclosure, a signal multiplexing method is provided, which can distinguish the first signal relayed by the relay device and the second signal directly interacted between the relay device and the base station, and transceive the two types of signals separately.

[0093] ​Further, in an embodiment of the present disclosure, the base station can not indicate the multiplexing manner to the relay device, but directly indicate the transceiving resource corresponding to the multiplexing manner to the relay device, and after the relay device determines the transceiving resource corresponding to the multiplexing manner indicated by the base station, the relay device can implicitly determine the corresponding multiplexing manner based on the transceiving resource.

[0094] Specifically, in an embodiment of the present disclosure, if the transceiving resource is time domain information, it can be determined that the multiplexing manner to be adopted should be TDM; if the transceiving resource is frequency domain information, it can be determined that the multiplexing manner to be adopted should be FDM; if the transceiving resource is beam information or polarization direction information or antenna port information, it can be determined that the multiplexing manner to be adopted should be SDM.

And the method of determining TDM and the transceiving resource corresponding to the manner of TDM can refer to the description of the above embodiments, which will not be described here in detail.

[0100] ​In an embodiment of the present disclosure, the first time and the second time can be time slot information or other time units, and the first time and the second time are not overlapped.

[0101] Further, according to the above embodiments, the method of determining the TDM manner corresponding to the transmission and reception resource can be determined based on a protocol agreement or based on a base station indication.

[0102] The following describes the method of determining the first time and the second time corresponding to the TDM manner based on a base station indication.

[0105] Method 2: determining the first time based on a base station indication (i.e., the base station only indicates the first time), and determining the second time as the time other than the first time within the power-on time / activation time of the relay device.

[0106] Method 3: determining the second time based on a base station indication (i.e., the base station only indicates the second time), and determining the first time as the time other than the first time within the power-on time / activation time of the relay device.

[0107] In an embodiment of the present disclosure, the above method of determining the first time and / or the second time based on a base station indication can include at least one of the following:

[0108] Method a: determining the first time and / or the second time based on RRC semi-static configuration of the base station.

[0109] Specifically, in an embodiment of the present disclosure, the method of determining the first time based on RRC semi-static configuration of the base station can include that the base station indicates the first time and the second time within a period of time to the relay device through RRC signaling, and the base station configures the use period and the period offset of the first time and the second time to the relay device, so that the relay device uses the first time and the second time to transmit and receive the first signal and the second signal in the TDM manner based on the configured use period and the period offset.

[0110] Method b: Based on the RRC configuration of the base station, determine the first time and / or the second time based on the dynamic activation of the MAC-CE of the base station.

[0111] Specifically, in one embodiment of this disclosure, determining the first time based on the dynamic activation of the base station's MAC-CE may include: the base station configuring a time information resource set to the relay device via RRC signaling; and, each time the relay device or the base station transmits and receives a first signal and / or a second signal, the base station may, in advance, dynamically indicate to the relay device via MAC-CE signaling the specific first time and / or the second time used for transmitting and receiving the second signal in the time information resource set, so that the relay device can transmit and receive the first signal using the corresponding first time and transmit and receive the second signal using the second time based on the dynamic activation of the base station's MAC-CE.

[0112] Method c: Based on the RRC configuration of the base station, determine the first time and / or the second time based on the DCI dynamic indication of the base station.

[0113] Specifically, in one embodiment of this disclosure, determining the first time based on the DCI dynamic activation of the base station may include: the base station configuring a time information resource set to the relay device via RRC signaling; and, each time the relay device or the base station transmits and receives a first signal and / or a second signal, the base station may dynamically indicate to the relay device via DCI signaling the first time and / or the second time used for transmitting and receiving the second signal in the time information resource set, so that the relay device can transmit and receive the first signal using the corresponding first time and transmit and receive the second signal using the second time based on the DCI dynamic indication of the base station.

[0114] Example, Figure 5b A schematic diagram of time slot allocation for a first time and a second time provided in an embodiment of this disclosure, as shown below. Figure 5b As shown, the first time slot can be the 2nd to 6th time slots and the 8th to 16th time slots, and the second time slot can be the 1st and 7th time slots. That is, the first signal (i.e., the forwarded signal) can be transmitted and received in the 2nd to 6th time slots and the 8th to 16th time slots, and the second signal (such as the PDCCH (Physical Downlink Control Channel) signal, the ACK (Acknowledgement) signal, or the NACK (Negative Acknowledgement) signal) can be transmitted and received in the 1st and 7th time slots.

[0115] In addition, in one embodiment of the present disclosure, the relay device can further receive TDD (Time Division Duplexing) configuration information sent by the base station. The TDD configuration information specifically indicates which time slots are used for uplink transmission, which time slots are used for downlink reception, and which time slots are used as flexible time slots. For example, referring to Figure 5b It can be seen that, among them, the D time slots can be used for downlink reception, the U time slots can be used for uplink transmission, and the F time slots can be used as flexible time slots, which can be used for uplink transmission or downlink reception.

[0116] In one embodiment of the present disclosure, the relay device can further receive FDD (Frequency Division Duplexing) configuration information sent by the base station. The present disclosure does not limit this.

[0117] Step 502, respectively transceiving the first signal and the second signal based on the TDM transceiving mode and the transceiving resources of the first signal and the second signal.

[0118] Specifically, referring to Figure 5b It can be seen that the relay device can receive the second signal (such as receiving the PDCCH signal sent by the base station) sent by the base station on the first time slot, send the second signal (such as sending the ACK signal or the NACK signal to the base station) to the base station on the seventh time slot, and receive the first signal sent by the base station on the second to third time slots and the eighth to sixteenth time slots, and send the first signal to the base station on the fifth time slot and the sixth time slot.

[0119] In summary, in the signal multiplexing method provided in the embodiments of the present disclosure, the relay device determines the multiplexing mode of the first signal and the second signal and the transceiving resources corresponding to the multiplexing mode, wherein the first signal can be the uplink signal and / or the downlink signal forwarded by the relay device, and the second signal can be the uplink signal and / or the downlink signal directly interacted between the relay device and the base station, and then the relay device respectively transceives the first signal and the second signal based on the multiplexing mode and the transceiving resources of the first signal and the second signal. Thus, in one embodiment of the present disclosure, a signal multiplexing method is provided, which can distinguish the first signal forwarded by the relay device and the second signal directly interacted between the relay device and the base station, and will separately transceive the two types of signals.

[0120] Figure 6a A flowchart of a signal multiplexing method provided in the embodiments of the present disclosure is applied to a relay device, as shown in Figure 6a The signal multiplexing method can include the following steps:

[0121] Step 601, determining that the corresponding transceiving resources of the first signal and the second signal are a first frequency and a second frequency.

[0122] In one embodiment of the present disclosure, when the determined transceiving resource is the first frequency and the second frequency, it can be determined that the relay device adopts the multiplexing mode FDM. The method of determining the FDM and the transceiving resource corresponding to the FDM mode can refer to the above embodiments, and the embodiments of the present disclosure will not be described here.

[0123] The FDM mode can be that a first signal is transceived at the first frequency and a second signal is transceived at the second frequency, and the first frequency and the second frequency are different at least in center frequency. Specifically, in one embodiment of the present disclosure, the first frequency and the second frequency can be different CCs (Carrier Components). In another embodiment of the present disclosure, the first frequency and the second frequency can be BWPs (Bandwidth Parts).

[0124] In one embodiment of the present disclosure, the duplex configuration (such as TDD configuration and / or FDD configuration) on the first frequency and the duplex configuration (such as TDD configuration and / or FDD configuration) on the second frequency can be the same or different. Specifically, if the relay device only receives one duplex configuration sent by the base station, it is defaulted that the duplex configuration on the first frequency and the duplex configuration on the second frequency are the same.

[0125] It should be noted that, in one embodiment of the present disclosure, by making the duplex configuration on the first frequency and the duplex configuration on the second frequency the same, self-interference can be reduced.

[0126] Further, as can be known from the above embodiments, the method of determining the transceiving resource corresponding to the FDM mode can be determined based on a protocol agreement or based on a base station indication.

[0127] The specific method of determining the first frequency and the second frequency corresponding to the FDM mode based on the base station indication is described in detail below.

Figure 6b

[0134] In step 602, the first signal and the second signal are respectively transmitted and received based on the FDM transmission mode and the transmission and reception resources of the first signal and the second signal.

[0135] Specifically, as shown in FIG. 6, the relay device can receive the first signal transmitted by the base station on the D time slot of the first frequency CC#2, and receive the first signal transmitted by the base station on the U time slot of the first frequency CC#2. In addition, the relay device can receive the second signal transmitted by the base station on the D time slot of the second frequency CC#1, and receive the second signal transmitted by the base station on the U time slot of the second frequency CC#1.

Specifically, if the relay device only receives one duplex configuration sent by the base station, it is assumed that the duplex configuration on the first beam or the first polarization direction or the first antenna port is the same as the duplex configuration on the second beam or the second polarization direction or the second antenna port.

[0145] Further, as can be known from the above embodiments, the method of determining the transceiving resource corresponding to the mode of the SDM can be determined based on a protocol agreement or based on a base station indication.

[0154] Method c: determining the first beam / polarization direction / antenna port and the second beam / polarization direction / antenna port based on DCI dynamic indication of the base station.

[0155] The methods of RRC semi-static configuration, MAC-CE dynamic activation, and DCI dynamic indication can be described in the above embodiments, and the present disclosure will not be repeated here.

[0156] In addition, the first antenna port and the second antenna port are determined based on the base station indication.
