Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a relay communication method, device, and storage medium. Background Art

[0002] The Network Controlled Repeater (NCR) enables low-cost relay communication between network devices and terminals to improve system coverage. The NCR consists of two parts: the Network Controlled Repeater Mobile Termination (NCR-MT) and the Network Controlled Repeater Forwarding (NCR-Fwd). The NCR-MT receives control commands from network devices, which control the behavior of the NCR-Fwd. These commands include side control information (SCI), such as beam direction and forwarding on and off.

[0003] When a time domain conflict occurs in the control information, for example, when a beam indication conflicts with another beam indication, that is, at least part of the application time of the two beams overlaps, NCR-Fwd will not be able to select the beam information that needs to be applied on the access link between the terminal and NCR.

[0056] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.

[0057] The relay communication method provided by the embodiment of the present disclosure can be applied to Figure 1 In the relay communication system shown in FIG. Figure 1 As shown, it includes network devices, network controlled repeater (NCR) devices, and terminals. The network devices transmit data to the terminals through the repeater devices.

[0058] The NCR consists of two parts: the Network Controlled Repeater Mobiletermination (NCR-MT) and the Network Controlled Repeater Forwarding (NCR-Fwd). The NCR-MT receives control commands from network devices over the control link. These control commands control the behavior of the NCR-Fwd, specifically the backhaul link and access link, such as beam direction and enabling and disabling forwarding.

[0059] Furthermore, the network devices involved in the present disclosure may also be referred to as wireless access network devices. The wireless access network device may be: a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It may also be a gNB in ​​an NR system, or it may also be a component or part of a base station. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network device are not limited. In the present disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located in the coverage area (cell).

[0060] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: smart phones (Mobile Phones), customer premises equipment, pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptop computers, tablet computers, wearable devices, or vehicle-mounted devices, etc. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0061] Furthermore, the relay device involved in the present disclosure may also be referred to as a repeater.

[0062] In addition, unless otherwise specified, the SCI signaling involved in the embodiments of the present disclosure refers to side control information (SCI).

[0063] In related technologies, network equipment can indicate priorities for different channels, such as by indicating the priorities of different physical downlink shared channels (PDSCH) in downlink control information (DCI). Network equipment can also inform the terminal of the priority through predefined rules, which is the priority of the beam or certain information received by the terminal. However, whether the network device indicates the priority through communication signaling or informs the terminal through predefined rules, the terminal needs to decode the obtained information before knowing it.

[0064] When network equipment transmits with limited power and high-frequency signal link loss is significant, distant terminals experience significant signal attenuation and are unable to receive or demodulate signals properly. By adding NCRs to the link, relay communication between network equipment and terminals can be performed at low cost, improving system coverage and increasing system capacity.

[0065] NCR is completely transparent to the terminal and does not decode the forwarded information, for example, it does not demodulate the forwarded control channel and data channel. Therefore, priority is reflected only in the control information sent by the network device to the relay device. If the control information conflicts in the time domain, such as when a beam indication conflicts with another beam indication in the time domain, that is, when at least part of the application time of the two beams overlaps, NCR-Fwd will be unable to select the beam information to be applied on the access link between the terminal and NCR.

[0066] Based on this, an embodiment of the present disclosure provides a relay communication method, which can determine the control information applied within the time domain conflict range from the multiple control information received by the relay device when a time domain conflict occurs.

[0067] Figure 2 is a flow chart showing a relay communication method according to an exemplary embodiment. Figure 2 As shown, the relay communication method is applied to a relay device and includes the following steps.

[0068] In step S11 , a plurality of control information sent by the network device to the relay device is acquired.

[0069] In step S12, it is determined that a time domain conflict occurs in a plurality of control information, and control information applied within the time domain conflict range is determined from the plurality of control information.

[0070] In an embodiment of the present disclosure, after obtaining multiple control information sent by a network device to a relay device, if it is determined that a time domain conflict occurs in the multiple control information, the control information applied within the time domain conflict range is determined from the multiple control information, thereby solving the problem that the relay device cannot determine the control information applied within the time domain conflict range when a time domain conflict occurs in the control information.

[0071] The following describes how to determine the control information to be applied within the time domain conflict range from multiple pieces of control information.

[0072] In a relay communication method provided by an embodiment of the present disclosure, control information applied within a time domain conflict range is determined from the multiple control information based on the priorities of the multiple control information.

[0073] Figure 3 is a flow chart showing a relay communication method according to an exemplary embodiment. Figure 3 As shown, the following steps are included:

[0074] In step S21, priorities of a plurality of control information are determined.

[0075] In step S22, based on the priorities of the plurality of control information, the control information to be applied within the time domain conflict range is determined.

[0076] In the embodiment of the present disclosure, by determining the priorities of multiple control information, the control information applied within the time domain conflict range is determined based on the priorities of the multiple control information, thereby solving the problem that the relay device cannot determine the control information applied within the time domain conflict range when a time domain conflict occurs in the control information.

[0077] In a relay communication method provided by an embodiment of the present disclosure, control information with the highest priority among multiple control information is determined as the control information applied within a time domain conflict range.

[0078] How to determine the priorities of multiple control information will be described below.

[0079] In a relay communication method provided by an embodiment of the present disclosure, the priorities of multiple control information are determined based on the priorities configured or indicated by communication signaling.

[0080] Figure 4 is a flow chart showing a relay communication method according to an exemplary embodiment. Figure 4 As shown, the following steps are included:

[0081] In step S31, the priorities of the plurality of control information are determined based on the priorities configured or indicated by the communication signaling.

[0082] The communication signaling includes at least one of the following: dynamic control signaling, radio resource control signaling RRC signaling, and media access control element MAC-CE signaling.

[0083] The dynamic control signaling includes DCI signaling and SCI signaling.

[0084] In step S32, based on the priorities of the plurality of control information, the control information to be applied within the time domain conflict range is determined.

[0085] In one implementation, based on the priority configured or indicated by the communication signaling, the control information with the highest priority is determined from multiple control information, and the control information with the highest priority is determined as the control information applied within the time domain conflict range.

[0086] In an implementation of a relay communication method provided by an embodiment of the present disclosure, the priorities of multiple control information are determined based on priority bits configured or indicated by communication signaling.

[0087] In an exemplary embodiment, the larger the priority bit, the higher the priority of the control information. Alternatively, the larger the priority bit, the lower the priority of the control information.

[0088] For example, the priority bit of control information 1 configured or indicated by communication signaling is 1, and the priority bit of control information 2 configured or indicated by communication signaling is 0. When the larger the priority bit, the higher the priority of the control information, the priority of control information 1 is higher than the priority of control information 2. Furthermore, control information 1 can be determined as the control information applied within the time domain conflict range.

[0089] In the embodiment of the present disclosure, the method of determining the priorities of multiple control information based on the priorities configured or indicated by communication signaling is more flexible. Different priorities can be configured for different control information based on different priority methods, so that the relay device can determine the control information applied within the time domain conflict range, which solves the problem that the relay device cannot determine the control information applied within the time domain conflict range when a time domain conflict occurs in the control information.

[0090] In a relay communication method provided by an embodiment of the present disclosure, priorities of multiple control information are determined based on predefined rules.

[0091] Figure 5 is a flow chart showing a relay communication method according to an exemplary embodiment. Figure 5 As shown, the following steps are included:

[0092] In step S41, the priorities of the plurality of control information are determined based on predefined rules.

[0093] In step S42, based on the priorities of the plurality of control information, the control information to be applied within the time domain conflict range is determined.

[0094] In one implementation, based on a predefined rule, control information with the highest priority is determined from multiple pieces of control information, and the control information with the highest priority is determined as the control information applied within the time domain conflict range.

[0095] In the embodiment of the present disclosure, the priorities of multiple control information are determined by means of predefined rules, without the need for additional signaling indications, thus saving signaling overhead, and at the same time enabling the relay device to determine the control information applied within the time domain conflict range, thereby solving the problem that the relay device cannot determine the control information applied within the time domain conflict range when a time domain conflict occurs in the control information.

[0096] In a relay communication method provided in an embodiment of the present disclosure, if there is the same priority among the priorities of multiple control information configured or indicated by communication signaling, the priorities of the multiple control information corresponding to the same priority are determined based on the time sequence of the control information corresponding to the same priority, the time domain configuration type, and at least one of the number of parameters contained in the control information.

[0097] Figure 6 is a flow chart showing a relay communication method according to an exemplary embodiment. Figure 6 As shown, the following steps are included:

[0098] In step S51, if there is the same priority among the priorities of multiple control information configured or indicated by the communication signaling, the priorities of the multiple control information corresponding to the same priority are determined based on the time sequence of the control information corresponding to the same priority, the time domain configuration type, and at least one of the number of parameters contained in the control information.

[0099] The time domain configuration type of the control information includes: a periodic time domain configuration type, a semi-static time domain configuration type, and a dynamic time domain configuration type.

[0100] In step S52, based on the priorities of multiple pieces of control information corresponding to the same priority, the control information to be applied within the time domain conflict range is determined.

[0101] In an implementation of a relay communication method provided by an embodiment of the present disclosure, the priorities of multiple control information corresponding to the same priority are determined based on the time sequence in which the control information corresponding to the same priority is acquired.

[0102] In an exemplary embodiment, the priority of the control information obtained at a first time is higher than the priority of the control information obtained at a second time, wherein the first time is later than the second time.

[0103] In the embodiment of the present disclosure, the most recently received control information has the highest priority, which can ensure the timeliness of the application of the control information.

[0104] In another implementation of a relay communication method provided by an embodiment of the present disclosure, the time domain configuration type is determined based on the control information corresponding to the same priority level.

[0105] In an exemplary embodiment, the priority of control information of periodic time domain configuration is higher than the priority of control information of dynamic time domain configuration, and the priority of control information of dynamic time domain configuration is higher than the priority of control information of semi-static time domain configuration.

[0106] For example, when the control information 1 of the periodic time domain configuration and the control information 2 of the dynamic time domain configuration configured or indicated by the communication signaling have the same priority, the control information 1 of the periodic time domain configuration has a higher priority than the control information 2 of the dynamic time domain configuration.

[0107] It should be noted that in the embodiment of the present disclosure, the time when the control information is obtained is not taken into consideration. Even if the control information 1 of the periodic time domain configuration is obtained earlier than the control information 2 of the dynamic time domain configuration, the priority of the control information 1 of the periodic time domain configuration is still higher than the control information 2 of the dynamic time domain configuration.

[0108] In the embodiment of the present disclosure, by making the priority of the control information of the periodic time domain configuration higher than the priority of the control information of the dynamic time domain configuration, and the priority of the control information of the dynamic time domain configuration higher than the priority of the control information of the semi-static time domain configuration, it is possible to ensure that the priority of the cell-level signaling is higher, and further, ensure that the priority of the control information of the more dynamic time domain configuration is the highest.

[0109] The above examples are merely examples. In the embodiment of the present disclosure, other priority rules may be set such that the priority of the control information of the dynamic time domain configuration is higher than the priority of the control information of the periodic time domain configuration.

[0110] In another implementation of a relay communication method provided by an embodiment of the present disclosure, the determination is based on the number of parameters included in the control information corresponding to the same priority.

[0111] In an exemplary embodiment, a control information having a first number of parameters has a higher priority than a control information having a second number of parameters, wherein the first number is greater than the second number.

[0112] For example, if the number of beams included in control information 1 is 3 or a beam group, and the number of beams included in control information 2 is 1, the priority of control information 1 is higher than the priority of control information 2.

[0113] In the embodiment of the present disclosure, by making the control information corresponding to the same priority have a higher priority if the control information includes more parameters, it can be ensured that the efficiency of applying the control information is higher.

[0114] In a relay communication method provided by an embodiment of the present disclosure, a predefined rule is determined based on a time domain configuration type of control information in which a time domain conflict occurs.

[0115] In a relay communication method provided by an embodiment of the present disclosure, if the time domain configuration type of the control information causing the time domain conflict is the same, the priority of the control information obtained at the first time is higher than the priority of the control information obtained at the second time, where the first time is later than the second time.

[0116] Furthermore, the control information acquired at the first time is determined as the control information applied within the time domain conflict range.

[0117] In an exemplary embodiment, if a time domain conflict occurs between control information of a semi-static time domain configuration and control information of a semi-static time domain configuration, the control information of the semi-static time domain configuration acquired at the first time is determined as the control information applied within the time domain conflict range.

[0118] In another exemplary embodiment, if a time domain conflict occurs between control information of a dynamic time domain configuration and control information of a dynamic time domain configuration, the control information of the dynamic time domain configuration acquired at the first time is determined as the control information applied within the time domain conflict range.

[0119] In the embodiment of the present disclosure, when the time domain configuration types of the control information that causes the time domain conflict are the same, the priority of the most recently acquired control information is predefined to be the highest, thereby ensuring the timeliness of the application of the control information.

[0120] In a relay communication method provided by an embodiment of the present disclosure, if the time domain configuration types of the control information causing the time domain conflict are different, the priority of the first control information is higher than the priority of the second control information, and the first control information and the second control information are different control information.

[0121] Furthermore, the first control information is determined as control information applied within a time domain conflict range.

[0122] In an exemplary embodiment, if a time domain conflict occurs between the control information of the periodic time domain configuration and the control information of the semi-static time domain configuration, the control information of the semi-static time domain configuration is determined as the control information applied within the time domain conflict range.

[0123] In an exemplary embodiment, if a time domain conflict occurs between the control information of the periodic time domain configuration and the control information of the semi-static time domain configuration, the control information of the periodic time domain configuration is determined as the control information applied within the time domain conflict range.

[0124] In another exemplary embodiment, if a time domain conflict occurs between the control information configured in the periodic time domain and the control information configured in the dynamic time domain, the control information configured in the dynamic time domain is determined as the control information applied within the time domain conflict range.

[0125] In another exemplary embodiment, if a time domain conflict occurs between the control information of the periodic time domain configuration and the control information of the dynamic time domain configuration, the control information of the periodic time domain configuration is determined as the control information applied within the time domain conflict range.

[0126] In yet another exemplary embodiment, if a time domain conflict occurs between the control information of the semi-static time domain configuration and the control information of the dynamic time domain configuration, the control information of the semi-static time domain configuration is determined as the control information applied within the time domain conflict range.

[0127] In another exemplary embodiment, if the control information of the semi-static time domain configuration conflicts with the control information of the dynamic time domain configuration, the control information of the dynamic time domain configuration is determined as the control information applied within the time domain conflict range.

[0128] In an embodiment of the present disclosure, when the time domain configuration types of the control information that causes a time domain conflict are different, by predefining a certain time domain configuration type as having the highest priority, the relay device can determine the control information applied within the time domain conflict range from the control information of multiple time domain configuration types based on the predefined time domain configuration type, thereby solving the problem that the relay device cannot determine the control information applied within the time domain conflict range when a time domain conflict occurs in the control information.

[0129] In a relay communication method provided by an embodiment of the present disclosure, the priority of the first control information is higher than the priority of the second control information; the first control information is configured or indicated to have priority by communication signaling, and the second control information is not configured with priority.

[0130] In an embodiment of the present disclosure, if, among multiple control information that have a time domain conflict, the first control information is configured or indicated to have priority by communication signaling, and the second control information is not configured or indicated to have priority by communication signaling, a default priority is configured for the second control information, such as the highest priority by default, and the priority of the first control information that is configured or indicated to have priority by communication signaling is lower than that of the first control information that is not configured or indicated to have priority by communication signaling.

[0131] In a relay communication method provided in an embodiment of the present disclosure, the control information includes at least one of the following:

[0132] A. beam information and / or beam group information;

[0133] The beam information includes at least one of the following: one or more beam IDs, one or more beam group IDs, beam type information, and beam width information.

[0135] C.UL-DL TDD information;

[0136] D. Power control information of the relay device.

[0137] The control information in the relay communication method involved in any of the above embodiments can be replaced by any one of the above A, B, C, and D.

[0138] The relay communication method involved in the above embodiment is described below by taking the example that the control information includes beam information and / or beam group information.

[0139] The situations in which the beam information and / or beam group information has a time domain conflict include at least one of the following:

[0140] A. The beam information and / or beam group information of two semi-static time domain configurations have a time domain conflict.

[0141] One implementation is to determine the priority of beam information and / or beam group information of two semi-static time domain configurations based on predefined rules.

[0142] In an exemplary embodiment, the beam information or beam group information of the semi-static time domain configuration acquired later is always used.

[0143] Another implementation is to determine the priority of beam information and / or beam group information of two semi-static time domain configurations based on the priority configured or indicated by communication signaling.

[0144] In an exemplary embodiment, a priority bit is added to the communication signaling, and the beam or beam group information to be applied is determined by comparing the priority bits.

[0145] The communication signaling may be RRC signaling or MAC CE signaling. For example, MAC CE signaling may be used to activate an RRC-configured beam, including beam ID, activation command, and priority bit.

[0151] The communication signaling may be SCI signaling.

[0154] In an exemplary embodiment, it is always ensured that the beam information and / or beam group information configured in the semi-static time domain has the highest priority.

[0155] In another exemplary embodiment, it is always ensured that the beam information and / or beam group information configured in the periodic time domain has the highest priority.
