Description

Technical Field

[0001] The present invention relates to the field of communication technologies.

Background Art

[0002] Compared with conventional 3G (3rd Generation Mobile Communication Technology) and 4G (4th Generation Mobile Communication Technology) systems, the 5G (5th Generation Mobile Communication Technology) system provides a wider bandwidth and a higher data rate, and can support more types of terminals and diverse industrial services.

[0003] Therefore, in addition to the conventional telecommunications spectrum, the 5G system is also deployed in new spectrums, and the frequencies of the new spectrums have significantly higher frequencies than the conventional telecommunications spectrum used by 3G and 4G systems. For example, the 5G system may be deployed in the millimeter wave band (such as 28 GHz, 38 GHz, 60 GHz and above).

[0004] According to the propagation rules of wireless signals, the higher the frequency of the carrier wave where the wireless signal is located, the greater the fading of the signal during propagation. Therefore, in actual deployment, the 5G system needs to strengthen the cell coverage more than the conventional 3G and 4G systems. Especially for the 5G system deployed in the millimeter wave band, how to better strengthen the cell coverage of the 5G system has become an urgent problem to be solved.

[0005] It should be noted that the above description of the background art is only for explaining the configuration of the present invention more clearly and completely, and is for the understanding of those skilled in the art. These configurations should not be interpreted as well-known technologies to those skilled in the art just because they are described in the background art part of the present invention.

Summary of the Invention

Problems to be Solved by the Invention

[0006] To better address coverage issues in cellular mobile communication systems in actual deployments, using radio frequency repeaters (RF Relays / Repeaters) to amplify and forward communication signals between terminal and network devices is a relatively common deployment method. Radio frequency repeaters are relatively widely used in the actual deployments of 3G and 4G systems. Typically, a radio frequency repeater is a device that amplifies and forwards signals between devices in the radio frequency domain. In other words, a radio frequency repeater is a non-regenerative relay node that simply amplifies and forwards all received signals directly.

[0007] According to the inventors of this invention, one feasible solution to the coverage problem in 5G system deployment is to enhance coverage using conventional radio frequency repeaters. However, the forwarding operation of conventional radio frequency repeaters is not controlled by network equipment. The effect of amplifying the signal to be forwarded is insufficient, and it can cause significant interference to other devices in the network, increasing system noise and interference levels, and potentially reducing network throughput. Specifically, taking antenna direction as an example, 5G systems use more advanced and complex MIMO (Multi-Input Multi-Output) technology compared to 3G and 4G systems. In 5G systems, especially at high carrier frequencies, directional antennas become a basic component of network equipment and terminal equipment, and signal transmission and reception based on beamforming technology is a basic signal transmission method in 5G systems. The direction and width of the (simulated) beam of network equipment and terminal equipment may change dynamically due to changes in position, etc. (i.e., beam switching (handover)). However, conventional radio frequency repeater antennas cannot dynamically adjust their direction, resulting in wider beams. The direction and width of their transmitting and receiving antennas cannot flexibly adapt to the dynamic changes in the position of network and terminal equipment, as well as the direction and width of the transmitting and receiving antennas' beams. When such radio frequency repeaters are deployed in a 5G system, the performance and effectiveness of the amplified / enhanced target signal may be insufficient because the direction and width of their transmitting and receiving antennas do not match the dynamic changes in the direction and width of the transmitting and receiving antennas of the network and terminal equipment. Furthermore, using a wider transmitting beam can cause significant interference to other equipment over a wider range (e.g., network equipment or terminal equipment), increasing the overall noise and interference levels of the system and potentially reducing network throughput.

[0008] To improve 3GPP Rel-18 NR coverage, network-controlled repeaters (NCRs) have been proposed for forwarding signals between network devices and terminal devices. NCRs can communicate directly with network devices via a control link to assist their forwarding operation.

[0009] According to the inventors of this invention, whether or not there may be overlap between time-domain resources or flexible symbols corresponding to the access link beam of a repeater, and how to handle such overlaps, is a problem that needs to be solved urgently.

[0010] In view of at least one of the above problems, embodiments of the present invention provide an information transmission method, an information reception method, a repeater, and a network device. [Means for solving the problem]

[0011] One embodiment of the present invention provides a network device comprising a transmitting unit that transmits a first instruction indicating a first time-domain resource, wherein the first time-domain resource overlaps with or does not overlap with a first flexible symbol and / or overlaps with or does not overlap with a second time-domain resource, and the second time-domain resource is indicated by a second instruction or by a first instruction.

[0012] Another embodiment of the present invention provides a repeater comprising a receiving unit that receives a first instruction indicating a first time-domain resource, wherein the first time-domain resource overlaps with or does not overlap with a first flexible symbol and / or overlaps with or does not overlap with a second time-domain resource, and the second time-domain resource is indicated by a second instruction or indicated by a first instruction.

[0013] Another embodiment of the present invention provides a communication system including the above-described repeater and / or network device.

[0014] One of the advantageous effects of the embodiments of the present invention is as follows: By clarifying whether or not there is overlap between time-domain resources or flexible symbols corresponding to access link beams, and how to handle overlaps, the time-domain resources on which the repeater performs forwarding (forwarding downlink / uplink signals) and the time-domain resources of the terminal device receiving / transmitting the signals match, thereby improving the effect of signal amplification / enhancement, saving power consumption of the repeater, reducing interference to other devices in the network, and improving network throughput.

[0031] Figure 1 is a schematic diagram of an example of an NCR according to an embodiment of the present invention. As shown in Figure 1, the NCR102 is positioned between the network device 101 and the terminal device 103. The NCR102 may include two modules / components, namely, a repeater mobile terminal (NCR-MT) and a repeater forwarding unit (NCR-Fwd). The NCR-Fwd is also referred to as the routing unit of the NCR-RU (NCR-RU).

Here, the C-link is used for communication between the NCR and the network device. The BH link is used for the repeater to receive signals to be forwarded from the network device, or to forward signals from terminal devices to the network device.

[0038] The following describes various embodiments of the present invention with reference to the drawings. These embodiments are merely examples and do not limit the present invention.

[0039] <Example 1> An embodiment of the present invention provides an information receiving method, which will be described from the perspective of the repeater.

[0040] Figure 2 is a schematic diagram of an example of an information receiving method according to an embodiment of the present invention. As shown in Figure 2, the method may include the following steps.

[0041] Step 201: The repeater receives a first instruction indicating a first time-domain resource, which overlaps with or does not overlap with a first flexible symbol and / or overlaps with or does not overlap with a second time-domain resource, which is indicated by a second instruction or by a first instruction.

[0042] Figure 2 above merely illustrates an embodiment of the present invention and is not limited thereto. For example, the execution order between each step may be adjusted as appropriate, or several other steps may be added, or some steps may be omitted. Those skilled in the art may modify the above content as appropriate and are not limited to the description in Figure 2 above.

[0043] In some embodiments, the first indicator (type) may be a periodic beam indicator, a semi-sustained beam indicator, or a dynamic beam indicator, and the second indicator may be a periodic beam indicator, a semi-sustained beam indicator, or a dynamic beam indicator.

[0044] Periodic beam instructions: Constitute a transfer resource or transfer resource list via RRC signaling. Each periodic beam instruction includes a transfer resource list, which includes a first information field beamIndex-r18 indicating an access link beam and a second information field periodicTimeResource-r18 indicating a time-domain resource. This second information field includes time-length information and / or offset information for time-domain resources within one period. A periodic beam instruction may also include period information and / or priority information priorityFlag-r18. A third information field referenceSCS-r18 for indicating a subcarrier interval is the reference subcarrier interval for all time-domain resources indicated by the periodic beam instruction, but embodiments of the present invention are not limited thereto. A network device may transmit one or more periodic beam instructions to the NCR. Each periodic beam instruction includes one or more of the first information field, second information field, third information field, period information periodicity-r18, and priority information, respectively. For example, it can be configured using the ToAddModList or other lists method. This allows for the configuration of one or more lists, where one list contains one of the aforementioned periodic beam indicators.

[0045] For example, the periodic beam indication is expressed using ASN.1 as follows:

[0046] [Table 1] For semi-sustained beam indications, the method of configuring the transfer resource list via RRC signaling is the same as for periodic beam indications, except that it includes MAC CEs that activate or deactivate the transfer resource list. For example, one first MAC CE (e.g., NCR Access Link Beam Indication MAC CE) activates or deactivates one semi-sustained transfer resource list.

[0047] For example, a semi-sustained beam indication is expressed using ASN.1 as follows:

[0048] [Table 2] Furthermore, the MAC CE configuration includes a Resource set ID field to indicate a single transfer in a semi-persistent resource list, as shown in Figure 11. A value of 1 in the Activate / Deactivate A / D field indicates activating the indicated resource, a value of 0 indicates deactivating the indicated resource, and vice versa. The Beam index ID field is used to indicate the beam index corresponding to the time-domain resource. It may also include reserved bits, etc.

[0049] For non-periodic beam indications, the following may be replaced by a DCI, which may include one or more first information fields for indicating a beam and one or more second information fields for indicating a time-domain resource. The DCI has / uses (may / may) a first DCI format specific to the repeater. The first DCI format or DCI is used to carry (aperiodic or dynamic) beam indication or side control information, and / or to transmit or notify (aperiodic / dynamic) beam indication or side control information of an access link, and / or to indicate (aperiodic or dynamic) forwarding time resources or forwarding resources, and / or to indicate that a repeater or the forwarding unit of a repeater is ON, and / or to indicate that an access link and / or a backhaul link is ON, and / or to indicate (aperiodic or dynamic) access link beams and / or time domain resources. This ON indicates that NCR-Fwd may (should) forward signals, or may forward signals in access links and / or backhaul links, including forwarding downlink signals transmitted from network devices to terminal devices and / or forwarding uplink signals transmitted from terminal devices to network devices. This first DCI format is a newly introduced DCI format (e.g., DCI format 5_0), is not used for scheduling PDSCH and / or PUSCH, and may be unicast. However, embodiments of the present invention are not limited thereto, and this DCI format may be an existing DCI format and / or be used for scheduling PDSCH and / or PUSCH, and / or be groupcast / multi-cast / broadcast.

[0050] In embodiments of the present invention, “downlink control information in the first DCI format,” “downlink control information using the first DCI format,” or “DCI in the first DCI format” may simply be referred to as “the first DCI format.” The same applies to other DCI formats.

[0051] In some embodiments, the first information field indicates a beam by indicating a beam index. The beam refers to an access link beam or a beam about an access link.

[0052] In some embodiments, the DCI includes one or more first information fields, where one first information field must indicate one or at most one beam (in other words, it does not have to indicate a beam). For example, first information fields (having / corresponding to) different sequence numbers must all indicate one beam, or not all may indicate a beam, or some (e.g., the first first information field) must indicate a beam and others (e.g., the other first information fields) may not indicate a beam.

[0053] In some embodiments, when the DCI includes a second information field, one second information field is used to indicate one time-domain resource index, or up to one time-domain resource index. This index may be replaced with a sequence number or identifier (ID). Cases where the DCI does not include a second information field will be discussed later, but the following first describes a case where the DCI includes a second information field as an example.

[0054] In some embodiments, the second information field indicates time-domain resources by a time-domain resource list. The time-domain resource list includes one or more time-domain resource configurations. A single time-domain resource configuration is defined by one or more parameters, for example, a slot offset (slotOffsetAperiodic-r18 for determining the starting slot), a symbol offset (symbolOffset-r18 for determining the starting symbol in the slot), and a symbol count (durationInSymbols-r18 for determining the duration of the time-domain resource). Here, the slot offset means the offset value between the slot in which the time-domain resource resides or the first slot in which the time-domain resource resides and a reference point. The symbol offset means the offset value between the first symbol of the time-domain resource and the slot in which it resides or the first symbol in the first slot in which it resides. The symbol offset and / or symbol count must, for example, ensure that the configured time-domain resources reside in the same slot, or the configured time-domain resources may reside in the same slot or between slots.

[0055] For example, the time-domain resource list may be constructed using RRC signaling.

[0056] [Table 3] In other words, information for adding and / or modifying time domain resources, ncr-AperiodicFwdTimeResourceToAddModList-r18 and ncr-AperiodicFwdTimeResourceToReleaseList-r18 (used to release / delete time domain resources), may constitute a list of such time domain resources.

[0057] The first and second instructions may be the same or different types of beam instructions.

[0058] For the same type: For example, the first and second indicators are periodic beam indicators. The first and second indicators are composed of different first information and / or identified by different IDs (for example, composed of second information (e.g., ncr-PeriodicFwdResourceId / periodicFwdRsrcId / PeriodicFwdRsrcId)).

[0059] For example, both the first and second instructions are semi-persistent beam instructions. That is, the first and second instructions are composed of different third pieces of information and / or identified by different IDs (e.g., composed of fourth pieces of information (ncr-SemiPersistentFwdResourceSetId / )) and / or activated / deactivated by different fifth pieces of information (MAC CE).

[0060] The first, second, third, and fourth pieces of information described above may be transmitted via RRC signaling.

[0061] For example, the first and second instructions are dynamic / non-periodic beam instructions. That is, the first and second instructions are carried / transmitted by different DCIs (of time-frequency resources) or PDCCHs that carry the DCIs.

[0062] In the following embodiments, overlap is also called duplication and represents partial overlap, incomplete overlap, or complete overlap. Overlap between a time-domain resource and a flexible symbol may be represented as the time-domain resource containing the flexible symbol. Non-overlap between a time-domain resource and a flexible symbol may be represented as the time-domain resource not containing the flexible symbol. Overlap between a first time-domain resource and a second time-domain resource may be represented as the first time-domain resource containing all or part of the second time-domain resource, or the second time-domain resource containing all or part of the first time-domain resource. Non-overlap between a first time-domain resource and a second time-domain resource may be represented as the first time-domain resource not containing (all) of the second time-domain resource, or the second time-domain resource not containing (all) of the first time-domain resource.

[0063] The following explains each situation.

[0064] (i) Whether or not the first time-domain resource and the first flexible symbol collide, and how to resolve the collision. In some embodiments, the first subcarrier interval of the first time-domain resource is the same as or different from the second subcarrier interval of the first flexible symbol. The first flexible symbol is a semi-static flexible symbol. For example, a repeater may determine the first flexible symbol by a TDD configuration. The TDD configuration includes a first TDD configuration (e.g., TDD-UL-DL-ConfigCommon) and / or a second TDD configuration (e.g., TDD-UL-DL-ConfigDedicated) received at the repeater's mobile terminal. For example, the first TDD configuration and / or the second TDD configuration may flexibly configure the transmission direction type for the time-domain resource, where the transmission direction type includes uplink, downlink, and flexible. Here, the second TDD configuration cannot override the downlink or uplink configured by the first TDD configuration. In other words, if the first TDD configuration configures a slot or symbol as downlink (or uplink), the second TDD configuration cannot reconfigure the slot or symbol as uplink or flexible (or downlink or flexible), and even if the second TDD configuration configures it as uplink or flexible (or downlink or flexible), the configuration of the first TDD configuration still takes precedence (it remains downlink (or uplink)). The second TDD configuration can override the flexible configuration of the first TDD configuration as downlink or uplink. In other words, if the first TDD configuration configures a slot or symbol as flexible, or not as uplink or downlink, the second TDD configuration may configure it as downlink or uplink, or as flexible.

[0065] In some embodiments, the first time-domain resource and the first flexible symbol do not overlap. The repeater does not expect the time-domain resource indicated by the first instruction (the first time-domain resource) and the first flexible symbol to overlap, or the repeater expects the time-domain resource indicated by the first instruction (the first time-domain resource) and the first flexible symbol to not overlap. In other words, it is necessary to avoid situations in which the first time-domain resource and the first flexible symbol overlap, or to avoid collisions between the first time-domain resource and the first flexible symbol, thereby eliminating the need for collision resolution.

[0066] In some embodiments, the first time-domain resource and the first flexible symbol may or may not overlap (a conflict may exist). The repeater does not expect the time-domain resource indicated by the first instruction (the first time-domain resource) and the first flexible symbol to completely overlap, or the repeater expects the time-domain resource indicated by the first instruction (the first time-domain resource) and the first flexible symbol to not completely overlap, or to partially overlap. In other words, it is necessary to avoid situations where the first time-domain resource and the first flexible symbol completely overlap, or the first time-domain resource must contain resources that do not overlap with the first flexible symbol.

[0067] In some embodiments, the first time-domain resource and the first flexible symbol may or may not overlap (a conflict may exist). The repeater does not expect the time-domain resource indicated by the first instruction (the first time-domain resource) and the first flexible symbol to partially overlap, or the repeater expects the time-domain resource indicated by the first instruction (the first time-domain resource) and the first flexible symbol to not overlap at all, or to completely overlap. In other words, it is necessary to avoid situations in which the first time-domain resource and the first flexible symbol partially overlap, or all symbols included in the first time-domain resource may be the first flexible symbol, or none of the symbols included in the first flexible symbol.

[0068] In some embodiments, if the first time-domain resource and the first flexible symbol overlap in a situation where the above-mentioned collision may exist, the repeater does not perform a transmission in the first time-domain resource.

[0069] Here, the first time-domain resource is indicated by the second information field (second information field X). The second information field X and / or the second information field following the second information field X do not indicate a time-domain resource and / or are invalid and / or are set to a second specific value and / or are ignored by the repeater and / or The first information field corresponding to the second information field and / or the first information field corresponding to the second information field following the second information field does not show a beam and / or is invalid and / or is set to a fourth specific value and / or is ignored by the repeater and / or The information field following the second information field is invalid and / or set to a fifth specific value and / or ignored by the repeater and / or The first information field included in the information block in which the second information field is located does not indicate a beam and / or is invalid and / or is set to a fourth specific value and / or is ignored by the repeater and / or The first information field contained in the information block following the information block in which the second information field is located does not indicate a beam and / or is invalid and / or is set to a fourth specific value and / or is ignored by the repeater and / or The second information field contained in the information block following the information block in which the second information field is located does not indicate a time-domain resource and / or is invalid and / or is set to a second specific value and / or is ignored by the repeater and / or The second information field is the last information field (of the downlink control information) and / or, The information block in which the second information field is located is the last information block (of the downlink control information) and / or The second information field is the last second information field (of the downlink control information) and / or, The first information field corresponding to the second information field is the last first information field (of the downlink control information) and / or, The second information field does not have a corresponding first information field.

[0070] In some embodiments, in situations where the above-mentioned collision may exist, if the first time-domain resource and the first flexible symbol overlap, the repeater may either not perform a transfer in the first sub-resource of the first time-domain resource, or perform a transfer and / or perform a transfer in the second sub-resource of the first time-domain resource, or not perform a transfer. The first sub-resource includes resources that overlap with the first flexible symbol (of the first time-domain resource) and / or resources that overlap with the first period. The second sub-resource includes resources that do not overlap with the first flexible symbol (of the first time-domain resource), or resources other than the first period among the resources that do not overlap with the first flexible symbol (of the first time-domain resource), or resources that do not overlap with the first flexible symbol (of the first time-domain resource) and do not overlap with the first period. The first period described above includes at least the duration of the first partial resource and / or processing time, which includes, for example, the on / off transition time of a repeater, but the embodiments of the present invention are not limited thereto.

[0071] Figures 7A to 7C are schematic diagrams of the overlap between time-domain resources and flexible symbols according to embodiments of the present invention. As shown in Figure 7A, in the first time-domain resource, the first four symbols are downlink symbols and the last eight symbols are first flexible symbols. Therefore, a transfer (downlink transfer) is performed in the first four symbols (second partial resource), but not in the last eight symbols (first partial resource). As shown in Figure 7B, in the first time-domain resource, the first four symbols (second partial resource) are downlink symbols and the last eight symbols (first partial resource) are first flexible symbols. No transfer is performed in the first time-domain resource. As shown in Figure 7C, in the first time-domain resource, the first two symbols are flexible symbols and the last ten symbols are uplink symbols. No transfer is performed in the first time-domain resource or the first two symbols (first partial resource), but a transfer is performed in the second partial resource (last nine symbols).

[0072] Whether or not the second time-domain resource and the second flexible symbol collide, and the embodiment of collision resolution, are the same as in (1), and are therefore omitted from this explanation. Here, the third subcarrier interval of the second time-domain resource and the fourth subcarrier interval of the second flexible symbol are the same or different. The configuration of the second flexible symbol may be described by referring to the first flexible symbol, and is therefore omitted from this explanation.

[0073] (ii) Whether or not the first time-domain resource and the second time-domain resource indicated by the first instruction conflict, and how to resolve the conflict. In some embodiments, the first subcarrier interval of a first time-domain resource and the third subcarrier interval of a second time-domain resource are the same or different. The first and second time-domain resources are indicated by different second information fields in the first instruction.

[0074] In some embodiments, the non-overlap of a first time-domain resource and a second time-domain resource means that different time-domain resources indicated by the same instruction (first instruction or second instruction) do not overlap or conflict. For example, a repeater does not expect different (two or more) time-domain resources indicated by a first instruction to overlap (or that time-domain resources indicated by different second information fields indicated first do not overlap), or a repeater expects different time-domain resources indicated by a first instruction to not overlap (or that time-domain resources indicated by different second information fields indicated by a first instruction do not overlap). In other words, it is necessary to avoid situations where the first time-domain resource and the first flexible symbol overlap, i.e., situations where the first time-domain resource and the second time-domain resource conflict, i.e., situations where time-domain resources indicated by different second information fields indicated by the first instruction conflict, and therefore, conflict resolution is unnecessary. For example, if the first instruction is DCI, then any two second information fields have different values ​​and / or different indicated time-domain resource indices and / or the time-domain resources included in the time-domain resource indices in the corresponding time-domain resource list do not overlap at all. Here, for example, the number of non-overlapping time-domain resources included in the time-domain resource list and / or the number of entries for non-overlapping time-domain resources is greater than or equal to the number of second information fields included in the DCI and / or the number of first information fields included in the DCI, but is not limited to this.

[0075] In some embodiments, if the first time-domain resource and the second time-domain resource overlap or do not overlap (a collision may occur), the repeater does not expect the different time-domain resources indicated by the first instruction to completely overlap, or the repeater expects the different time-domain resources indicated by the first instruction to not completely overlap or to partially overlap. In other words, it is necessary to avoid a situation where the first time-domain resource and the second time-domain resource completely overlap. For example, if the first instruction is DCI, the values ​​of the second information field indicating the first time-domain resource and the second information field indicating the second time-domain resource may be different, and the time-domain resources included in the time-domain resource index in the time-domain resource list corresponding to those values ​​may not completely overlap.

[0076] In some embodiments, if a first time-domain resource and a second time-domain resource overlap or do not overlap (overlap or collision may occur), the repeater does not expect the different time-domain resources indicated by the first instruction to partially overlap, or the repeater expects the different time-domain resources indicated by the first instruction to either not overlap at all or to completely overlap. For example, if the first instruction is DCI, the second information field indicating the first time-domain resource and the second information field indicating the second time-domain resource have the same value (they overlap completely). Alternatively, for example, the number of non-overlapping time-domain resources and / or the number of entries for non-overlapping time-domain resources in the time-domain resource list is greater than or equal to the number of second information fields in the DCI and / or the number of first information fields in the DCI. The values ​​of the second information field indicating the first time-domain resource and the second information field indicating the second time-domain resource are different, and the time-domain resources included in the time-domain resource index in the time-domain resource list corresponding to those values ​​do not overlap at all.

[0077] In some embodiments, the beams shown for the first time-domain resource and the second time-domain resource are the same or different.

[0078] In some embodiments, in situations where the above collision may occur, if the first time-domain resource and the second time-domain resource overlap, the repeater does not perform transmission in the second time-domain resource, or does not perform transmission in the portion of the second time-domain resource that does not overlap with the first time-domain resource, and / or performs transmission in the first time-domain resource (using the first beam), or performs transmission in the portion of the first time-domain resource that does not overlap with the second time-domain resource (using the first beam).

[0079] In some embodiments, in situations where the above collisions may occur, if the first time-domain resource and the second time-domain resource overlap, the repeater performs a transfer in the union of the first time-domain resource and the second time-domain resource (using the same beam, e.g., the first beam or the second beam).

[0080] In the above embodiment, the second information field Y for indicating a second time-domain resource is located after the second information field X for indicating a first time-domain resource. The second information field Y and / or the second information field after the second information field Y do not indicate a time-domain resource and / or are invalid and / or are set to a second specific value and / or are ignored by the repeater and / or The first information field corresponding to the second information field Y and / or the first information field corresponding to the second information field after the second information field does not show a beam and / or is invalid and / or is set to a fourth specific value and / or is ignored by the repeater and / or The information field following the second information field Y is invalid and / or set to a fifth specific value and / or ignored by the repeater and / or The first information field contained in the information block where the second information field Y is located does not indicate a beam and / or is invalid and / or is set to a fourth specific value and / or is ignored by the repeater and / or The first information field contained in the information block following the information block in which the second information field Y is located does not indicate a beam and / or is invalid and / or is set to a fourth specific value and / or is ignored by the repeater and / or The second information field contained in the information block following the information block in which the second information field Y is located does not indicate a time-domain resource and / or is invalid and / or is set to a second specific value and / or is ignored by the repeater and / or The second information field Y is the last information field (of the downlink control information), and / or The information block in which the second information field Y is located is the last information block (of the downlink control information), and / or The second information field Y is the last second information field (of the downlink control information), and / or The first information field corresponding to the second information field Y is the last first information field (of the downlink control information), and / or The second information field Y does not have a corresponding first information field.

[0081] In the above embodiment, each specific value is represented in binary, and all bits may be 0 or all bits may be 1. Also, for example, in the decimal example, each specific value may be 0.

[0082] Figures 8A to 8C are schematic diagrams of overlapping time-domain resources (indicated by the same reference) according to embodiments of the present invention. As shown in Figure 8A, if two symbols overlap between the first time-domain resource and the second time-domain resource, a transfer is performed (using the first beam) in the portion of the first time-domain resource that does not overlap with the second time-domain resource, and no transfer is performed in the second time-domain resource and the portion of the first time-domain resource that does not overlap with the second time-domain resource. As shown in Figure 8B, if two symbols overlap between the first time-domain resource and the second time-domain resource, and the first beam and the second beam must be the same, a transfer is performed in the first time-domain resource and the second time-domain resource (using the same beam, e.g., the first beam or the second beam). As shown in Figure 8C, if the second information field Y for indicating the second time-domain resource is after the second information field X for indicating the first time-domain resource, and there is an overlap of two symbols between the first and second time-domain resources, then the first beam is used to perform the transfer in the first time-domain resource, and no transfer is performed in the portion of the second time-domain resource that does not overlap with the first time-domain resource.

[0083] In the above embodiment, the first beam is indicated by a first information field corresponding to a second information field indicating a first time-domain resource, i.e., it is the beam corresponding to the first time-domain resource indicated by the first instruction. The second beam is indicated by a first information field corresponding to a second information field indicating a second time-domain resource, i.e., it is the beam corresponding to the second time-domain resource indicated by the first instruction.

[0084] (iii) Whether or not the first time-domain resource and the second time-domain resource indicated by the second instruction conflict, and how to resolve the conflict. In some embodiments, the first subcarrier interval of the first time-domain resource and the third subcarrier interval of the second time-domain resource are the same or different. The priority of the first instruction and the priority of the second instruction are the same or different.

[0085] The priority order for each type of beam indication is as follows: semi-sustaining beam indication A (with priority flag configured and activated) > periodic beam indication A (with priority flag configured) > aperiodic beam indication > semi-sustaining beam indication B (without priority flag configured and activated) > periodic beam indication B (without priority flag configured). One or more of these may be configured / provided for the NCR, and each type may have one or more beam indications.

[0086] For aperiodic beam indications, a later aperiodic beam indication received in the time domain takes precedence over an earlier aperiodic beam indication. In other words, for DCIs using a first DCI format received at different time-domain locations, a later DCI indication in the time domain takes precedence over an earlier DCI indication.

[0087] If multiple (two or more) beam instructions with different priorities collide, the transfer will be performed according to the higher / highest priority beam instruction.

[0088] For example, a collision means that time-domain resources indicated by multiple beam directives of different priorities partially or completely overlap. For instance, a transfer is performed using the corresponding beam indicated by a higher / highest priority beam directive for a time-domain resource, while ignoring time-domain resources and / or beams indicated by lower priority beam directives.

[0089] Furthermore, a collision, for example, means a situation where time-domain resources indicated by multiple beam directives of different priorities partially or completely overlap, and the beams indicating them are different. For example, a transfer might be performed using the corresponding beam indicated by the higher / highest priority beam for a time-domain resource, while ignoring the time-domain resources and / or beams indicated by the lower priority beam directive. Alternatively, a transfer might be performed using the corresponding beam indicated by the higher / highest priority beam directive in the overlapping portion, and no transfer might be performed in the non-overlapping portion, or transfers might be performed using the corresponding beams indicated in each portion.

[0090] In some embodiments, the NCR does not expect more than N beams (e.g., 2) to collide. For example, if there is overlap in time-domain resources indicated by two (differently prioritized) beam indications, the NCR does not expect a third time-domain resource indicated by a third (differently prioritized) beam indication to overlap with the aforementioned overlapping portion. Also, for example, if there is overlap in time-domain resources indicated by two (differently prioritized) beam indications, and the corresponding beams indicated are different, the NCR does not expect a third time-domain resource indicated by a third (differently prioritized) beam indication to overlap with the aforementioned overlapping portion, or it does not expect a third time-domain resource indicated by a third (differently prioritized) beam indication to overlap with the aforementioned overlapping portion and indicate other different beams.

[0091] In embodiments of the present invention, it is possible to determine whether the priority of the first instruction and the priority of the second instruction are the same according to the priority order described above, and if they are different, to determine which of the first instruction and the second instruction has a higher priority and which has a lower priority, and then to perform the following processing according to the result of the determination.

[0092] (1) The priority of the first instruction and the priority of the second instruction are the same, and the following instructions having the same priority include, but are not limited to, the first instruction and the second instruction.

[0093] In some embodiments, the non-overlap of the first time-domain resource and the second time-domain resource includes the repeater not expecting time-domain resources indicated by the same priority indication to overlap, or the repeater expecting time-domain resources indicated by the same priority indication to not overlap. As a result, the first time-domain resource and the second time-domain resource do not conflict, and no conflict resolution is required.

[0094] In some embodiments, the first time-domain resource and the second time-domain resource may overlap or not overlap (a collision may occur), and the repeater may not expect the time-domain resources indicated by the same priority indication to partially overlap, or the repeater may expect the time-domain resources indicated by the same priority indication to not overlap at all or to completely overlap. In other words, it is necessary to avoid a situation where the first time-domain resource and the second time-domain resource completely overlap, i.e., the first time-domain resource must include resources that do not overlap with the second time-domain resource.

[0095] In some embodiments, if a collision is possible, and the first time-domain resource and the second time-domain resource overlap, the repeater does not perform a transfer in the second time-domain resource, or does not perform a transfer in a portion of the second time-domain resource that does not overlap with the first time-domain resource, and / or performs a transfer in the first time-domain resource (using the first beam), or performs a transfer in a portion of the first time-domain resource that does not overlap with the second time-domain resource (using the first beam). Here, the beam shown for the first time-domain resource and the beam shown for the second time-domain resource may be the same or different.

[0096] In some embodiments, if a collision is possible and the first time-domain resource and the second time-domain resource overlap, the repeater performs a transfer in the union of the first time-domain resource and the second time-domain resource (using the same beam, e.g., the first beam or the second beam). Here, the beam indicated for the first time-domain resource and the beam indicated for the second time-domain resource may be the same or different.

[0097] In some embodiments, the situation in (1) is similar to the situation in (ii), and for details, please refer to the schematic diagrams in Figures 8A to 8C, which will be omitted here.

[0098] (2) The second instruction takes precedence over the first instruction. The following instructions of different priorities include, but are not limited to, the first and second instructions.

[0099] In some embodiments, the overlap or non-overlapping of the first time-domain resource and the second time-domain resource further includes the fact that the repeater does not expect the time-domain resources indicated by different priority indications to partially overlap, or that the time-domain resources indicated by different priority indications do not completely overlap, or completely overlap. In other words, by avoiding partial overlap of the time-domain resources indicated by different priority indications, the first time-domain resource and the second time-domain resource are completely identical if they completely overlap.

[0100] In some embodiments, the first time-domain resource and the second time-domain resource overlap. If the first and second time-domain resources overlap, the repeater uses the second beam in the third time-domain resource and / or does not perform a transfer in the fourth time-domain resource. The third time-domain resource is either the first time-domain resource, or the second time-domain resource, or the union of the second and first time-domain resources, or includes resources from the second time-domain resource that do not overlap with the first time-domain resource. The fourth time-domain resource includes resources from the first time-domain resource that do not overlap with the second time-domain resource, and / or resources from the second time-domain resource that overlap with the first time-domain resource. In other words, if the first and second time-domain resources overlap (the first instruction and the second instruction collide, i.e., the first time-domain resource and the second time-domain resource collide), the transfer is performed according to the second instruction, which has a higher priority.

[0101] In some embodiments, the first time-domain resource and the second time-domain resource overlap (partially). If the first and second time-domain resources overlap, the repeater uses the second beam in the fifth time-domain resource and / or uses the first beam in the sixth time-domain resource and / or does not perform transmission in the second period. The fifth time-domain resource includes some or all of the resources that overlap with the first and second time-domain resources, and / or some or all of the resources in the second time-domain resource that do not overlap with the first time-domain resource. The sixth time-domain resource includes some or all of the resources in the first time-domain resource that do not overlap with the second time-domain resource. The above second period includes at least processing time in the portion of the first time-domain resource that does not overlap with the second time-domain resource, and such processing time includes, for example, beam switching time, but embodiments of the present invention are not limited thereto.

[0102] Figures 9A to 9D are schematic diagrams of overlapping time-domain resources (indicated by different instructions) according to embodiments of the present invention. As shown in Figure 9A, if two symbols overlap between the first time-domain resource and the second time-domain resource, and the second instruction takes precedence over the first instruction, the transfer is performed using the second beam in the second time-domain resource, and the transfer is not performed in the partial resource of the first time-domain resource that does not overlap with the second time-domain resource. As shown in Figure 9B, if two symbols overlap between the first time-domain resource and the second time-domain resource, and the second instruction takes precedence over the first instruction, the transfer is performed using the second beam in the third time-domain resource (including the union of the first and second time-domain resources). As shown in Figure 9C, if two symbols overlap between the first time-domain resource and the second time-domain resource, and the second instruction takes precedence over the first instruction, the transfer is performed using the second beam in the second time-domain resource, and the transfer is performed using the first beam in the sixth time-domain resource that does not overlap with the second time-domain resource of the first time-domain resource. As shown in Figure 9D, if two symbols overlap between the first time-domain resource and the second time-domain resource, and the second instruction takes precedence over the first instruction, the transfer is performed using the second beam in the second time-domain resource, the transfer is performed using the first beam in the sixth time-domain resource (the portion of the first time-domain resource that does not overlap with the second time-domain resource), and no transfer is performed in the second period.

[0103] In the above embodiment, the first beam is indicated by a first information field corresponding to a second information field indicating a first time-domain resource, i.e., it is the beam corresponding to the first time-domain resource indicated by the first instruction. The second beam is indicated by a first information field corresponding to a second information field indicating a second time-domain resource, i.e., it is the beam corresponding to the second time-domain resource indicated by the second instruction.

[0104] In some embodiments, embodiments (i) and (ii) above may be combined and / or embodiments (i) and (iii) above may be combined.

[0105] In some embodiments, first, it may be considered whether the different time-domain resources (shown) overlap with the flexible symbols, and if they do, the overlapping symbols may be removed from the time-domain resources (the remainder being called a partial time-domain resource), and it may be determined whether there are any overlaps in the remaining portion of the time-domain resources, and then collision handling in (ii) or (iii) may be performed.

[0106] For example, the first instruction indicates the seventh time-domain resource. The third partial time-domain resource, which does not overlap with the first flexible symbol of the seventh time-domain resource, and the fourth partial time-domain resource, which does not overlap with the second flexible symbol of the eighth time-domain resource, may or may not overlap. The eighth time-domain resource is indicated by the second instruction or by the first instruction. The instruction methods for the seventh and eighth time-domain resources are the same as described above, and their explanation is omitted here. The third and fourth partial time-domain resources described above are considered to be the first and second time-domain resources described above, and the processes of (ii) and (iii) are executed.

[0107] In some embodiments, first, it is considered whether there is overlap between the different time-domain resources (shown), and if there is overlap, the process is carried out according to embodiments (ii) and (iii) above to determine whether the third time-domain resource, fourth time-domain resource, fifth time-domain resource, and sixth time-domain resource overlap with the flexible symbol, and the collision processing of (i) is performed.

[0108] For example, the first instruction information indicates the seventh time-domain resource. The seventh time-domain resource and the eighth time-domain resource overlap, and processing according to the embodiments of (ii) and (iii) above is performed to obtain a non-transferable fifth partial time-domain resource, and the sixth partial resource is obtained by excluding the fifth partial resource from the union of the seventh time-domain resource and the eighth time-domain resource, and it is determined whether the sixth partial resource overlaps with the third flexible symbol (which may be the first flexible symbol or the second flexible symbol) or not. The eighth time-domain resource is indicated by the second instruction or by the first instruction. The sixth partial time-domain resource is considered to be the first time-domain resource and the second time-domain resource, and processing (i) is performed.

[0109] Figures 10A and 10B are schematic diagrams of the overlap between time-domain resources and flexible symbols. As shown in Figure 10A, first, the portions that overlap with flexible symbols are removed from the 7th and 8th time-domain resources, respectively, to obtain the 3rd and 4th partial time-domain resources. If the 3rd partial time-domain resource (i.e., the 1st time-domain resource) and the 4th partial time-domain resource (i.e., the 2nd time-domain resource) do not overlap, a transfer is performed using the 2nd beam in the 2nd time-domain resource, a transfer is performed using the 1st beam in the 1st time-domain resource, and no transfer is performed in the remaining resources other than the 1st and 2nd time-domain resources in the union of the 7th and 8th time-domain resources. As shown in Figure 10B, first, resources that cannot be transferred due to resource overlap are removed according to method (ii) or (iii), and then resources that overlap with flexible symbols are removed from the remaining resources, after which a transfer is performed using the 2nd beam, and no transfer is performed in the remaining positions in the 7th and 8th time-domain resources.

[0110] The above embodiments are merely illustrative examples of the present invention, and the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, each of the above embodiments may be used individually, or one or more of the above embodiments may be used in combination.

[0111] According to embodiments of the present invention, by clarifying whether or not there is overlap between time-domain resources or flexible symbols corresponding to access link beams, and how to handle overlaps, the time-domain resources on which the repeater performs forwarding (forwarding downlink / uplink signals) and the time-domain resources of the terminal device receiving / transmitting the signals coincide. This improves the signal amplification / enhancement effect, saves power consumption of the repeater, reduces interference to other devices in the network, and improves network throughput.

[0112] <Example 2> The embodiments of the present invention provide an information transmission method and will be described from the perspective of the network device. Descriptions of the same content as in Embodiment 1 will be omitted.

[0113] Figure 3 is a schematic diagram of an example of an information transmission method according to an embodiment of the present invention. As shown in Figure 3, the method includes the following steps.

[0114] Step 301: The network device transmits a first instruction to the repeater indicating a first time-domain resource, which overlaps with or does not overlap with a first flexible symbol and / or overlaps with or does not overlap with a second time-domain resource, which is indicated by a second instruction or by a first instruction.

[0115] For an example of whether or not duplication occurs, and how to handle it if it does occur, refer to Example 1, and its explanation will be omitted here.

[0116] Figure 3 above merely illustrates an embodiment of the present invention and is not limited thereto. For example, the execution order between each step may be adjusted as appropriate, or several other steps may be added, or some steps may be omitted. Those skilled in the art may modify the above content as appropriate and are not limited to the description in Figure 3 above.

[0117] The above describes only the steps or processes related to the present invention, but the present invention is not limited thereto.

[0119] <Example 3> An embodiment of the present invention provides a repeater. The repeater may be, for example, the NCR described above, a network device or terminal device having a forwarding function, or one or more components configured in the NCR, network device or terminal device.

[0120] Figure 4 is a schematic diagram of an example of a repeater according to an embodiment of the present invention. The principle of solving the problem of this repeater is the same as that of the method in Example 1, so the specific implementation may refer to the method in Example 1, and redundant explanations of similar content will be omitted.

[0121] As shown in Figure 4, the repeater 400 further includes a receiving unit 401.

[0122] The receiving unit 401 receives a first instruction indicating a first time-domain resource. The first time-domain resource overlaps with or does not overlap with a first flexible symbol and / or overlaps with or does not overlap with a second time-domain resource, the second time-domain resource being indicated by a second instruction or by a first instruction.

[0123] Alternatively, the receiving unit 401 receives a first instruction indicating a time-domain resource.

[0124] The receiving unit 401 does not expect the time-domain resource indicated by the first gear instruction and the first flexible symbol to overlap, or expects the time-domain resource indicated by the first instruction and the first flexible symbol to not overlap, and / or The receiving unit 401 does not expect time-domain resources indicated by indications of the same priority to overlap, or expects that time-domain resources indicated by indications of the same priority will not overlap, and / or The receiving unit 401 does not expect time-domain resources indicated by different priority indications to partially overlap, or it expects time-domain resources indicated by different priority indications to not overlap at all, or to completely overlap.

[0125] For an embodiment of whether or not duplication occurs and how it is handled if it does, please refer to Example 1, which will be omitted here.

[0126] In some embodiments, the repeater may further include a processing unit (not shown).

[0127] The processing unit does not perform the transfer in the first time domain resource.

[0128] Alternatively, the processing unit may either not perform a transfer in the first partial resource of the first time domain resource, or perform a transfer and / or perform a transfer in the second partial resource of the first time domain resource, or not perform a transfer.

[0129] Alternatively, the processing unit may choose not to perform a transfer in the second time domain resource, or not to perform a transfer in a portion of the second time domain resource that does not overlap with the first time domain resource, and / or perform a transfer in the first time domain resource, or perform a transfer in a portion of the first time domain resource that does not overlap with the second time domain resource.

[0130] Alternatively, the processing unit performs a transfer in the union of the first time-domain resource and the second time-domain resource.

[0131] Alternatively, the processing unit may use the second beam in the third time-domain resource and / or not perform the transfer in the fourth time-domain resource.

[0132] Alternatively, the processing unit may use the second beam in the fifth time-domain resource and / or use the first beam in the sixth time-domain resource and / or not perform the transfer in the second period.

[0133] You may refer to Example 1 for the processing scenario and processing method of the processing unit.
