Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of communications.
Background Art
[0002] Compared with the conventional 2G (Second Generation Mobile Communication Technology), 3G (Third Generation Mobile Communication Technology), and 4G (Fourth Generation Mobile Communication Technology) systems, the 5G (Fifth Generation Mobile Communication Technology) system can provide a larger bandwidth and a higher data rate, and can support more types of terminals and vertical services. Therefore, the frequency band range / working bandwidth supported by the 5G system is significantly higher than that of the 2G, 3G, and 4G systems. In addition, the 5G system supports a higher carrier frequency. For example, the 5G system can be deployed in the millimeter wave band.
[0003] However, the higher the carrier frequency, the more severe the fading (attenuation) that the signal encounters during transmission. Therefore, when actually deploying the 5G system, how to better enhance cell coverage, especially in the millimeter wave band, has become a problem to be solved.
[0004] It should be noted that the introduction of the above background art is for clearly and completely explaining the technical solution of the present invention and for easy understanding by those skilled in the art. These technical solutions should not be construed as well-known to those skilled in the art just because they are described in the background art of the present invention.
Summary of the Invention
Problems to be Solved by the Invention
[0005] To better address coverage issues when deploying cellular mobile communication systems, a commonly used deployment method involves using RF relays (RF relays / repeaters) to amplify and forward signals between devices. RF relays have a wide range of applications when deploying 2G, 3G, and 4G systems. Their advantages include low cost, ease of deployment, and minimal latency. Generally speaking, an RF relay is a device that amplifies and forwards round-trip signals between devices in the RF band. In other words, an RF relay is a non-regenerative relay node; it simply amplifies and forwards all received signals directly.
[0006] Conventional RF transceivers do not possess communication capabilities. In other words, conventional RF transceivers cannot exchange information with other devices (e.g., base stations / terminal devices). Specifically, in the case of reception, conventional RF transceivers do not support measurement / demodulation / decoding of the transmitted signal, nor do they receive signals other than the transmitted signal. Furthermore, in the case of transmission, conventional RF transceivers only amplify and transmit signals, and do not support signal generation or transmission of signals they themselves have generated.
[0007] Therefore, conventional RF transmitter working-related settings (e.g., amplification gain, antenna direction) are typically set or adjusted manually and cannot be adjusted adaptively and / or dynamically. For example, antenna direction is usually set and adjusted manually during initial installation so that the base station antenna points in the direction of the base station's incoming wave and the terminal antenna points where deployment enhancement is needed. Similarly, amplification gain is also set and adjusted during initial installation to achieve the desired coverage enhancement effect as much as possible.
[0008] The inventors discovered the following: When deploying 5G systems, one feasible solution to the coverage problem is to enhance coverage using RF transceivers. However, conventional RF transceivers lack communication capabilities and cannot adaptively and / or dynamically adjust transmission power / amplification gain and / or beam direction / beam width. This can lead to significant interference with other surrounding equipment, and they cannot be flexibly adjusted to avoid interference as much as possible. This can increase the level of noise interference in the system and reduce system throughput. Therefore, in order to reduce interference and support adaptive and / or dynamic beam management and / or power control of RF transceivers, RF transceivers need to have communication capabilities in addition to the signal transmission capabilities mentioned above. In other words, RF transceivers not only need to transmit signals, but also need to exchange information with other equipment (e.g., base stations / terminal equipment). For example, it needs to receive signals (transmit signals or signals other than transmit signals) (e.g., including measurement / demodulation / decoding), generate signals (e.g., including encoding / modulation / sequencing), and transmit the signals it has generated. However, there is currently no known method for transmitting and / or generating transmit signals, and especially when a transmitter needs to transmit multiple (more than one) signals (e.g., transmit signals and generated signals) simultaneously, there is currently no discussion of how to determine which signals to transmit and how to transmit the signals that need to be transmitted.
[0009] In view of at least one of the above-mentioned problems, embodiments of the present invention provide a signal transmission method, an information transmission method, and an apparatus. [Means for solving the problem]

[0030] The following describes various embodiments of the present invention in conjunction with the drawings. These embodiments are merely illustrative and do not limit the present invention.
[0031] <Example of the first side view> An embodiment of the present invention provides a signal transmission method, which will be described starting from the transfer device side.
[0032] Figure 2 shows a signal transmission method for a transporter in an embodiment of the present invention. As shown in Figure 2, the method includes the following steps.
[0033] Step 201: The transmitter determines the transmission power of the first signal and / or the transmission power of the second signal; and Step 202: The transmitter transmits or does not transmit the first signal and / or the second signal.
[0034] According to the embodiment described above, by determining the transmission power of the transfer signal and / or generated signal using the transceiver, the transceiver can control the power when it is necessary to transmit the transfer signal and / or generated signal simultaneously. This avoids power limitations and improves the overall transmission efficiency and throughput of the network.
[0035] Figure 2 above is provided to illustrate an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, or some operations can be added or removed. Those skilled in the art can make appropriate modifications to the above description without being limited to Figure 2.
[0036] In embodiments of the present invention, the transceiver may further be called a repeater, RF transceiver, relay, RF relay, or a repeater node, transceiver node, relay node, or an intelligent repeater, intelligent transceiver, intelligent relay, intelligent repeater node, intelligent transceiver node, or intelligent relay node. However, the present invention does not limit the name of the transceiver, and all devices capable of realizing the functions described later belong to the scope of the transceiver of the present invention.
[0037] In embodiments of the present invention, the transceiver may be a network device and / or a terminal device, and the transceiver has one or more corresponding identifiers (IDs) for uniquely identifying the transceiver. When there are multiple identifiers for identifying the transceiver, the different identifiers have different uses or functions. One identifier may have one or more uses or functions, and the uses and functions of different identifiers may or may not overlap. The above-mentioned 'different uses or functions' means that the uses or functions of different identifiers are not exactly the same / do not overlap.
[0038] For example, one or more signs may be used for at least one of the following items, one sign may be used for one or more items, and items corresponding to different signs may or may not intersect or overlap, i.e., Used in network devices to uniquely identify the network device; Used in terminal devices to uniquely identify the terminal device; Used to identify or manage the connection between the transceiver and (one or more) network devices; and It is used to identify or manage the connection between the transceiver and (one or more) terminal devices.
[0039] For example, the one or more indicators may be, for instance, IMSI, or a dedicated RNTI or CGI for the transporter, and the one or more indicators may be, for example, pre-configured, pre-defined, or configured by signaling, but the embodiments of the present invention are not limited thereto.
[0040] In embodiments of the present invention, the signals interacted between the transporter and other devices include a transport signal and a communication signal, of which the transporter can transport a signal between a first device and a second device (or a signal generated by the first device and / or a signal generated by the second device), and this signal is referred to as the transport signal. The transporter receives, amplifies, and transmits the transport signal in the RF band. Generally, the transporter performs signal processing such as frequency conversion, filtering, and amplification on the received transport signal before transmitting it. The transporter can also receive a communication signal (also referred to as a received communication signal), and the transporter needs to perform measurement and / or demodulation and / or decoding on the communication signal. Alternatively, the transporter can transmit a communication signal (also referred to as a transmitted communication signal or a generated signal), and in order to transmit the communication signal, the transporter needs to perform sequence generation and / or encoding and / or modulation, and the transport signal and communication signal transmitted by the transporter may be transmitted independently, or they may be combined into a single signal and transmitted. For example, one or any combination of time-division (TD), frequency-division (FD), code-division (CD), and spatial-division methods may be used, but the present invention is not limited thereto.
[0041] In some embodiments, when a signal belongs to a forwarding signal, the receiving of the signal by the transceiver means that the transceiver receives the signal in the RF band (i.e., the transceiver does not perform measurement and / or demodulation and / or decoding on the signal) and the transceiver transmits the signal in the RF band (i.e., the transceiver does not perform sequence generation and / or encoding and / or modulation to transmit the signal). When a signal belongs to a communication signal, the receiving of the signal by the transceiver (assuming the signal belongs to a received communication signal) includes the transceiver performing measurement and / or demodulation and / or decoding on the signal, and when the transceiver transmits the signal (assuming the signal belongs to a transmitted communication signal), it is necessary to perform sequence generation and / or encoding and / or modulation to transmit the signal.
[0042] In some embodiments, the communication signals include communication signals between the transceiver and the first device, and / or communication signals between the transceiver and the second device, and / or communication signals between the transceiver and the third device. The communication signals between the transceiver and the first device also include signals transmitted by the first device to the transceiver (e.g., referred to as the first downlink communication signal or the first received communication signal) and / or signals transmitted by the transceiver to the first device (e.g., referred to as the first uplink communication signal or the first transmitted communication signal or the first generated signal or the first uplink generated signal). Similarly, the communication signals between the transceiver and the second device include signals transmitted by the transceiver to the second device (e.g., referred to as the second downlink communication signal or the second transmitted communication signal or the second generated signal or the downlink generated signal) and / or signals transmitted by the second device to the transceiver (e.g., referred to as the second uplink communication signal or the second received communication signal). Communication signals between the transponder and the third device include signals transmitted by the third device to the transponder (e.g., referred to as the third downlink communication signal or the third received communication signal) and / or signals transmitted by the transponder to the third device (e.g., referred to as the third uplink communication signal, the third transmitted communication signal, the third generated signal, or the second uplink generated signal).
[0043] Figure 3 shows the signal interaction between the first device, the second device, and the transporter. As shown in Figure 3, the transport signal includes the first transport signal and the second transport signal (A1, A2, A1', A2'), and the transporter can perform signal processing such as receiving, filtering, amplifying, and transmitting on the transport signal, but cannot decode and / or demodulate and / or measure it. The communication signal includes the third received signal, the fourth received signal, the third transmitted signal, and the fourth transmitted signal, and the transporter needs to decode and / or demodulate and / or measure the third received signal and / or the fourth received signal, or the transporter needs to generate the third transmitted signal and / or the fourth transmitted signal, and the generation operation includes generating a sequence corresponding to the third transmitted signal and / or the fourth transmitted signal, and performing encoding and / or modulation, etc. (generated based on or without the third received signal and / or the fourth received signal, also referred to as the first generated signal and / or the second generated signal), of which the third received signal and / or the fourth received signal include a reference signal, etc.
[0044] It should be noted that not all signals that need to be transmitted are called transmitted signals. The transmitted signals mentioned above refer only to transmitted signals that the transmitter cannot decode and / or demodulate and / or measure. For example, when a transmitter receives a third received signal (e.g., a reference signal and / or configuration information) (including decoding and / or demodulating and / or measuring it), it may transmit the third received signal to a second device (or may not transmit it), but since the transmitter performs operations such as decoding and / or demodulating and / or measuring on the third received signal, the third received signal is also called a communication signal.
[0045] In some embodiments, the signal awaiting transmission of the transceiver includes a transmission signal and a generated signal, the generated signal may be generated spontaneously by the transceiver or based on a received communication signal, for example, the transceiver may measure or demodulate / decode the information carried by the received communication signal and generate a signal based on the measured result and the decoded information. In some embodiments, the transmission signal includes a first transmission signal (also called the first transmission signal or uplink transmission signal) to be transmitted to a first device and a second transmission signal (also called the second transmission signal or downlink transmission signal) to be transmitted to a second device, the generated signal includes a third transmission signal (a first generated signal or uplink generated signal) generated by the transceiver and transmitted to the first device, and a fourth transmission signal (a second generated signal or downlink generated signal) generated by the transceiver and transmitted to the second device. The first device is a first terminal device, the second device is a second terminal device, or the first device is a network device, the second device is a terminal device, or the first device is a first network device, the second device is a second network device.
[0046] Taking the example that the first device is a network device and the second device is a terminal device, the first generated signal includes PRACH, PUCCH, PUSCH, and SRS, and the second generated signal includes SSB, CSI-RS, and SRS. The first forwarded signal is a downlink signal and includes, for example, SSB (including PSS, SSS, PBCH, and PBCH DMRS), CSI-RS, PDCCH, PDSCH, DM-RS, PT-RS, PRS, etc., and the second forwarded signal is an uplink signal and includes, for example, PRACH, PUCCH, PUSCH, SRS, etc., but a comprehensive list is omitted here.
[0047] Taking the example that both the first and second devices are terminal devices, the first generated signal, the second generated signal, the first transmitted signal, and the second transmitted signal each include, for example, S-SSB (S-PSS, S-SSS, PSBCH, PSBCH with DMRS), PSSCH, PSCCH, PSFCH, DMRS, PT-RS, CSI-RS, SRS, etc.
[0048] Taking the example that both the first and second devices are network devices, the first generated signal, second generated signal, first forwarded signal, and second forwarded signal each include, for example, inter-node message, SSB, CSI-RS, PDCCH, PDSCH, PRS, PRACH, PUCCH, PUSCH, SRS, etc., but a comprehensive list is omitted here.
[0049] When a transceiver needs to transmit multiple signals simultaneously, for example, when an RF transceiver needs to transmit a signal it has generated to another device, the method in the embodiment of the present invention can determine whether to transmit the transfer signal and / or the generated signal, and how to transmit the signals that need to be transmitted.
[0050] The following explanation will use the example that multiple signals include a first signal and a second signal, but the embodiments of the present invention are not limited thereto. For example, the multiple signals may further include other signals, or may include multiple different first signals and / or multiple different second signals, but an exhaustive list will be omitted here.
[0051] In embodiments of the present invention, the first signal and the second signal in 201 belong to the transfer signals or generated signals of the above-described transfer device, or may be said as follows: the first signal includes a transfer signal and / or a generated signal, and the second signal includes a transfer signal and / or a generated signal. For example, the first signal and the second signal may be any two combinations of the first transmission signal, the second transmission signal, the third transmission signal, and the fourth transmission signal. For example, the first signal and the second signal may be signals transmitted to the same terminal device or signals transmitted to different terminal devices, or both the first signal and the second signal may be transfer signals or both may be generated signals, or one may be a transfer signal and the other a generated signal. However, embodiments of the present invention are not limited thereto.
[0052] In embodiments of the present invention, the first signal and the second signal may overlap in the time domain; for example, the time domain resources of the first signal and the time domain resources of the second signal may completely overlap or partially overlap. Alternatively, the time domain interval between the first signal and the second signal may be less than or equal to a first predetermined value; for example, the time domain resources of the first signal and the time domain resources of the second signal may not overlap, and the interval between them may be less than or equal to a first predetermined value. The first predetermined value may be pre-set, pre-defined, or set by signaling. The first signal and the second signal may or may not be time-division multiplexed (TDM). For example, when the signal of a transporter includes multiple signals, the multiple signals may overlap in the time domain, or the time domain interval may be less than or equal to a first predetermined value, but an exhaustive list is omitted here.
[0053] In embodiments of the present invention, the first signal and the second signal may be located on the same carrier or different carriers, may correspond to the same cell or the same set of cells, may correspond to different cells, may be signals of the same frequency or signals of different frequencies, but the present invention is not limited thereto.
[0054] In embodiments of the present invention, in step 201, the transporter can allocate the transmission power of the first signal and / or the transmission power of the second signal based on priority, and / or determine whether to transmit the first signal and / or the second signal.
[0055] In some embodiments, the transporter can allocate the transmit power of the first and / or second signals based on priority when the transmit power is limited. However, the present invention is not limited thereto, and the transporter can also allocate the transmit power of the first and / or second signals based on priority when the transmit power is not limited.
[0056] In some embodiments, priority may be related to whether the signal is a generated signal or a transmitted signal, or it may be related to the recipient (destination) of the transmitted signal.
[0057] For example, the priorities may be as follows: the priority of the signal generated by the transporter may be higher or lower than the priority of the signal transmitted by the transporter, and / or the priority of the transmission signal on the first device side of the transporter may be higher or lower than the priority of the transmission signal on the second device side.
[0058] In some embodiments, when the transfer signal of the transfer device includes a first transfer signal and a second transfer signal, the priorities of the first and second transfer signals may be the same or different. Similarly, when the transfer signal of the transfer device includes a first transfer signal and a second transfer signal, the priorities of the first and second transfer signals may be the same or different.
[0059] In some embodiments, the transmission signal from the first device may include a first transfer signal and / or a first generated signal, and the transmission signal from the second device may include a second transfer signal and / or a second generated signal. When the transmission signal from the first device includes a first transfer signal and a first generated signal, the priority of the first transfer signal and the first generated signal may be the same or different. When the transmission signal from the second device includes a second transfer signal and a second generated signal, the priority of the second transfer signal and the second generated signal may be the same or different.
[0060] For example, the priority of each signal may be as follows (and will be sorted in descending order of priority below), that is, First generated signal, second generated signal, first forwarded signal, second forwarded signal; or First transmission signal, second transmission signal, first generated signal, second generated signal; or First generated signal, first transmitted signal, second generated signal, second transmitted signal; or Second generated signal, second transmitted signal, first generated signal, first transmitted signal; or Second transmission signal, second generated signal, first transmission signal, first generated signal; or Second generated signal, first generated signal, second transmitted signal, first transmitted signal That is the case.
[0061] However, the present invention is not limited thereto. For example, as can be seen from the foregoing, the priority of the first transfer signal and / or the second transfer signal may be the same, the priority of the first generated signal and the second generated signal may be the same, or the priority of the first transfer signal and the first generated signal may be the same, or the priority of the second transfer signal and the second generated signal may be the same, but a comprehensive list is omitted here.
[0062] In some embodiments, priority may also be related to the signal type. For example, priority decreases or increases sequentially according to the signal types SRS, PUCCH, PUSCH, and PRACH. For example, when the priority of the first and second signals is the same, the priority may be determined by considering the signal types of the first and / or second signals. For example, suppose the first and second signals are the first generated signal and the second generated signal, respectively, and when the first signal is PRACH, the priority of the first signal is higher than that of the second signal, and when the first signal is SRS, the priority of the first signal is lower than that of the second signal. Also, suppose the first and second signals are the first generated signal and the second forwarded signal, respectively, and when the first signal is PRACH, the priority of the first signal is higher than that of the second signal, and when the first signal is SRS, the priority of the first signal is lower than that of the first signal. For example, the priority of each signal may be as follows (hereinafter sorted in descending order of priority), i.e., First generated signal (PRACH), first generated signal (PUSCH), first generated signal (PUCCH), transfer signal, first generated signal (SRS) That is the case.
[0063] Please note that the above are merely examples, and a comprehensive list will be omitted here.
[0064] In some embodiments, priorities may be set from various dimensions. For example, priorities may exist between signals of the same frequency and / or between signals of different frequencies and / or between signals on the same side and / or between signals on different sides and / or between transferred signals and / or between generated signals and / or between cells and / or between cell groups. Each of these will be explained below.
[0065] For example, priority may exist between the transfer signals and / or between the generated signals. For instance, suppose the first signal and the second signal are the first generated signal and the second generated signal, respectively, and the priority between the first generated signal and the second generated signal is determined based on any one of the above examples. Alternatively, suppose the first signal and the second signal are the first transfer signal and the second transfer signal, respectively, and the priority between the first transfer signal and the second transfer signal is determined based on any one of the above examples.
[0066] For example, priority may exist between signals on the same side and / or between signals on different sides. Signals on the same side may mean that the first and second signals have the same transmission direction, i.e., the same receiving target, while signals on different sides may mean that the first and second signals have different transmission directions, i.e., different receiving targets. For example, suppose the first and second signals are the first and third transmission signals (on the same side), and the priority between the first and third transmission signals is determined based on any one of the above examples, or suppose the first and second signals are the first and fourth transmission signals (on different sides), and the priority between the first and fourth transmission signals is determined based on any one of the above examples.
[0067] For example, priority may exist between signals of the same frequency and / or between signals of different frequencies. Signals of the same frequency may refer to the first and second signals being located in the same frequency range, while signals of different frequencies may refer to the first and second signals being located in different frequency ranges. For example, suppose the first and second signals are the first and second transmission signals (of the same frequency), and the priority between the first and second transmission signals is determined based on any one of the above examples, or suppose the first and second signals are the first and second transmission signals (of different frequencies), and the priority between the first and second transmission signals is determined based on any one of the above examples, and in this case, when priority exists between signals of different frequencies, the priority within multiple frequency band ranges of different frequencies may be set uniformly, or the priority within multiple frequency band ranges of different frequencies may be set independently within each frequency band range.
[0068] For example, priority may exist between cells (or pairs of cells). For instance, suppose the first signal and the second signal are the first and second transmission signals (corresponding to the same cell or pair of cells), and the priority between the first and second transmission signals is determined based on any one of the examples above.
[0069] The priorities of each of the dimensions described above may be set individually or in combination, but the present invention is not limited thereto (the above example uses individual implementation), and an exhaustive list is omitted here.
[0070] In some embodiments, priority may be predefined or set by signaling. For example, the transponder may receive signaling from a third device and determine the power of the signal waiting to be transmitted based on the signaling. The third device may be a network device and / or terminal device, and may be one of the first and second devices, or a different device from the first and second devices, for example, when the third device is a network device, the third device may be the transponder's serving device / or cell.
[0071] In some embodiments, if the priority of the first signal is higher than that of the second signal, the transporter preferentially allocates the transmission power of the first signal and / or does not transmit the second signal, and / or, if the priority of the second signal is higher than that of the first signal, the transporter preferentially allocates the transmission power of the second signal and / or does not transmit the first signal.
[0072] For example, the transmitter allocates power sequentially according to priority. It preferentially allocates transmit power to the signal with the highest priority, and then allocates power to signals with lower priority according to priority. When the remaining power is insufficient to transmit a signal with lower priority than the highest priority, it either does not transmit that signal or any signal with lower priority than that signal, or it allocates the remaining power to signals with lower priority than the highest priority and does not transmit any signal with lower priority than that signal, or it sets a weight for each signal with lower priority than the highest priority based on priority (used to reduce the actual transmit power of each signal), for example, the higher the priority, the greater the weight, and the actual transmit power of each signal with lower priority than the highest priority = predetermined transmit power * weight, and the sum of the actual transmit powers of each signal with lower priority than the highest priority is less than or equal to the maximum transmit power, and the transmitter allocates transmit power to each signal with lower priority than the highest priority based on the weighted actual transmit power.
[0073] Furthermore, for example, the transmitter assigns weights to all pending signals based on priority, with higher priority signals having larger weights. The actual transmit power of each signal is equal to a predetermined transmit power * weight, and the sum of the actual transmit powers of all signals is less than or equal to the maximum transmit power. The transmitter allocates transmit power for each signal according to the weighted actual transmit power.
[0074] Furthermore, for example, a transmitter will prioritize allocating transmit power to the highest priority signal and will not transmit signals with a lower priority than the highest priority.
[0075] In some embodiments, the transporter can determine the transmit power of the first and / or second signals when transmit power is limited. For example, the transporter determines the transmit power of the first and second signals respectively, and if the sum of the transmit powers of the first and second signals exceeds the first maximum transmit power, the transporter adjusts the transmit power of the first and / or second signals, and / or allocates the transmit power of the first and / or second signals based on priority, and / or does not transmit the first or second signal.
[0076] The transfer unit may adjust the transmission power of the first and / or second signals in various ways. For example, each transfer unit can determine a weighting factor for the transmission power of the first and / or second signals, and obtain the adjusted transmission power by multiplying the transmission power of the first and / or second signals before adjustment by the weighting factor. The determined weighting factor allows the sum of the adjusted transmission powers of the signals waiting to be transmitted (first and / or second signals) to be less than or equal to the first maximum transmission power. The transfer unit transmits the first and / or second signals at the adjusted transmission power. The weighting factors for the first and second signals may be the same or different. The present invention is not limited thereto, and the transmission power of the first and / or second signals may be adjusted in other ways.
[0077] For methods in which the transceiver allocates the transmission power of the first signal and / or the second signal based on priority, and for methods in which the transceiver does not transmit the first or second signal, please refer to the methods described above, and a detailed explanation will be omitted here.
[0078] In some embodiments, the first signal and the second signal may reside in the same cell group, which corresponds to the first maximum transmit power. That is, when the signals awaiting transmission reside in the same cell group, the maximum transmit power of the transporter may be determined based on the first maximum transmit power corresponding to the first cell group. Among these, the cell group may be replaced by a "carrier group," a "frequency band group," etc.
[0079] In some embodiments, each transceiver can determine the transmission power of the first and second signals, and when the sum of the transmission powers of the first and second signals exceeds the second maximum transmission power, the transceiver adjusts the transmission power of the first and / or second signals, and / or allocates the transmission power of the first and / or second signals based on priority, and / or does not transmit the first or second signal.
[0080] Regarding the methods in which the transceiver adjusts or allocates the transmission power, and the methods in which the transceiver does not transmit the first or second signal, please refer to the methods described above, and a detailed explanation will be omitted here.
[0081] In some embodiments, the first and second signals may reside in different cell sets, where the different cell sets correspond to the second maximum transmit power. That is, when the signals awaiting transmission reside in different cell sets, the maximum transmit power of the transporter may be determined based on the second maximum transmit power corresponding to the different cell sets. For example, the maximum transmit power of the transporter may be any value, minimum, maximum, average, or weighted average of the second maximum transmit powers corresponding to the different sets, or the sum of the second maximum transmit powers corresponding to some or all of the different sets.
[0082] The above explains how to allocate (adjust) the transmission power of each signal based on priority. The predetermined transmission power may be indicated by first instruction information and / or second instruction information, and / or determined or calculated by a transfer device. However, prior art can be used to determine or calculate the transmission power of the transfer device, and the present invention is not limited thereto.
[0083] In some embodiments, the transporter can receive first and / or second instruction information of a third device transmission, the first instruction information may be used to specify parameters relating to the first signal transmission power, and the second instruction information may be used to specify parameters relating to the second signal transmission power. This allows the transporter to determine the transmission power of the pending signal based on these parameters.
[0084] In this embodiment, “parameter” may be replaced with “setting.” The above-described first instruction information and second instruction information may be set directly by the third device on the transceiver, or the third device may instruct the transceiver based on the measurement results reported by the first or second device, but the embodiments of the present invention are not limited thereto. The above-described first instruction information and / or second instruction information may be transmitted in part with side control information, which may include, for example, signals / information for setting / instructing the working parameters of the transceiver, and / or signals / information for establishing a connection between the transceiver and the network device and / or terminal device, but the present invention is not limited thereto. For example, the side control information may be carried by a third downlink communication signal.
[0085] In some embodiments, the first instruction information may include the transmit power and / or amplification gain of the transferor, or the maximum transmit power and / or maximum amplification gain of the transferor. The transferor can determine the transmit power and / or amplification gain of the first signal based on the first instruction information, that is, the transferor can transmit the first signal with the transmit power and / or amplification gain determined based on the first instruction information. When the first instruction information is the transmit power and / or amplification gain of the transferor, the transferor can directly determine the transmit power and / or amplification gain of the first signal, and when the first instruction information is the maximum transmit power and / or maximum amplification gain, the transferor can determine the transmit power and / or amplification gain of the first signal based on the maximum transmit power and / or maximum amplification gain. For specific implementations, refer to the relevant art.
[0086] In some embodiments, the second instruction information may include the transmit power and / or amplification gain of the transferor, or the maximum transmit power and / or maximum amplification gain of the transferor. The transferor can determine the transmit power and / or amplification gain of the second signal based on the second instruction information, that is, the transferor can transmit the second signal using the transmit power and / or amplification gain determined based on the second instruction information. When the second instruction information is the transmit power and / or amplification gain of the transferor, the transferor can directly determine the transmit power and / or amplification gain of the second signal, and when the second instruction information is the maximum transmit power and / or maximum amplification gain, the transferor can determine the transmit power and / or amplification gain of the second signal based on the maximum transmit power and / or maximum amplification gain. Specific implementations can be found in the relevant technologies. However, the present invention is not limited thereto; the first and second instruction information may be other information.
[0087] In embodiments of the present invention, a network device can support (serve) one or more cells, and such one or more cells may be referred to as a served cell. In some cases, the network device may be referred to as a cell or a serving cell, and an exhaustive list is omitted here. For example, the first device is a network device, the second device is a terminal device, and the cell served by the first device may be referred to as the first cell, or as follows: namely, the transceiver is used to amplify the downlink and / or uplink signals of the first cell. The first cell may or may not be the serving cell of the transceiver and / or terminal device. In embodiments of the present invention, the transceiver, the first device and the second device are located in different geographical locations and there is no wired (e.g., optical fiber) connection between them. That is, signals are transmitted / received between the transceiver, the first device and the second device via an air interface.
[0088] In some embodiments, a connection exists between the transporter and the third device, and a connection may or may not exist between the transporter and the second device. A connection may or may not exist between the first device and the second device. The existence of a connection means, for example, that communication or information interaction can take place between the devices, for example, that user plane data can be transmitted / received (including demodulation / decoding) between the devices, and / or that data that can be transmitted under RRC connection conditions can be transmitted / received (including demodulation / decoding) between the devices, and / or that data scrambled by a dedicated signal (e.g., RNTI) can be transmitted / received (including demodulation / decoding) between the devices.
[0089] In some embodiments, the third device is a network device.
[0090] In some embodiments, when a connection exists between two devices, one device may be referred to as the serving device or serving cell (if the one device is a network device) or parent node of the other device. For example, when a connection exists between a transceiver and a third device, the third device is the serving device, serving cell, or parent node of the transceiver. For example, the transceiver accesses the third device (or the cell served by the third device) by a random access procedure to establish a connection with the third device, and the cell is the serving cell of the transceiver. Also, for example, when the first device and the second device are a network device and a terminal device, respectively, and a connection exists between the first device and the second device, the network device is the serving device (or serving cell) of the terminal device. However, embodiments of the present invention are not limited to these.
[0091] In some embodiments, the third device is the first device, meaning that the transporter not only has a connection with the third device but also transports signals transmitted by the third device and / or signals transmitted by other devices to the third device. For example, the transporter serves one or more first devices (in terms of signal amplification), and one or more of these first devices are also the third device. In other words, the communication signals between the transporter and the third device are the communication signals between the transporter and the first devices. For example, the first (third) device may be a serving device, serving cell, or parent node of the transporter. However, the present invention is not limited thereto, and the third device may be a different device from the first and second devices.
[0092] In embodiments of the present invention, there may be one or more transfer devices used between the first device and the second device, that is, the signal between the first device and the second device may be amplified once or multiple times, and each of the multiple transfer devices may use the same method to amplify and transfer the signal. The following explanation will use one transfer device as an example. When there are multiple transfer devices between the first device and the second device, the signal received by one of the transfer devices may be the signal transmitted by the first device, or it may be the signal after it has been amplified by another transfer device. Figure 5 is a diagram showing a transfer scenario of the transfer devices. As shown in Figure 5, there are two transfer devices 1021 and 1022 between the first device 101 and the second device 1031, a transfer device 1023 between the first device 101 and the second device 1032, and a transfer device 1024 between the first device 101 and the second device 1033.
[0093] In embodiments of the present invention, a single transceiver may serve one or more first or second devices, and the working frequencies of the different first or second devices may be the same or different. Figures 6 and 7 illustrate transceiver forwarding scenarios. As shown in Figure 6, transceiver 102 serves two network devices 1011 and 1012 with two different working frequencies, and the working frequencies of two terminal devices 1031 and 1032 may be the same or different. As shown in Figure 7, transceiver 102 serves two network devices 1011 and 1012 with the same working frequency.
[0094] An embodiment of the present invention provides an information transmission method, which includes the following steps (not shown):
[0095] The third device transmits first instruction information and / or second instruction information, the first instruction information is used to specify parameters related to the transmission power of the first signal, and the second instruction information is used to specify parameters related to the transmission power of the second signal. The implementation method is as described above, and a detailed explanation is omitted here.
[0096] Although only steps or processes related to the present invention have been described above, the present invention is not limited thereto. The methods in the embodiments of the present invention may further include other steps or processes, and the specific details of these steps or processes can be found in the relevant art.
[0097] The embodiments described above are for illustrative purposes to illustrate embodiments of the present invention, but the present invention is not limited thereto, and appropriate modifications may be made based on the embodiments described above. For example, the embodiments described above may be used individually, or a combination of several of the embodiments described above may be used.
[0098] According to an embodiment of the present invention, by determining the transmission power of the transfer signal and / or generated signal using a transceiver, the transceiver can perform power control when it is necessary to transmit the transfer signal and / or generated signal simultaneously. This avoids power limitations and improves the overall transmission efficiency and throughput of the network.

Since the principle by which the device solves the problem is the same as the method in the embodiment of the first aspect, for its specific implementation, refer to the implementation of the method in the embodiment of the first aspect, and redundant explanations that are the same or related are omitted here.

[0112] In the embodiments of this invention, priority is related to the type of signal.

[0114] In the embodiments of the present invention, the first generated signal includes PRACH, PUCCH, PUSCH, and SRS, and the second generated signal includes SSB, CSI-RS, and SRS.
[0115] In embodiments of the present invention, when the priority of the first signal is higher than that of the second signal, the determination module 801 determines to preferentially allocate the transmission power of the first signal and / or not transmit the second signal, and / or when the priority of the second signal is higher than that of the first signal, the determination module 801 determines to preferentially allocate the transmission power of the second signal and / or not transmit the first signal.
[0116] In embodiments of the present invention, priority may be predefined or set by signaling.
[0117] In embodiments of the present invention, the first signal and the second signal are located on the same carrier or on different carriers.
[0118] In embodiments of the present invention, each determination module 801 determines the transmission power of the first signal and the second signal, adjusts the transmission power of the first signal and / or the second signal if the sum of the transmission powers of the first signal and the second signal exceeds the first maximum transmission power, and / or allocates the transmission power of the first signal and / or the second signal based on priority, and / or determines not to transmit the first signal or the second signal.

[0126] In embodiments of the present invention, the transfer module 902 may or may not transmit a transfer signal based on the final result of the processing module 901. For example, the transfer module 902 may amplify and transmit the transfer signal based on the final result of the processing module 901.

[0129] In embodiments of the present invention, an information transmission device is provided, and the information transmission is installed in a third device. Since the principle by which the device solves the problem is the same as the method in the embodiment of the first aspect, for its specific implementation, refer to the implementation of the method in the embodiment of the first aspect, and redundant explanations that are the same or related are omitted here.
[0130] Figure 4 shows an information transmission device in an embodiment of the present invention. As shown in Figure 4, the information transmission device 400 includes the following:
[0131] Transmitting unit 401: Transmits first instruction information and / or second instruction information. The first instruction information is used to specify parameters related to the transmission power of the first signal, and the second instruction information is used to specify parameters related to the transmission power of the second signal. The implementation method is as described above, and a detailed explanation is omitted here.
[0132] Although only the components or modules related to the present invention have been described above, the present invention is not limited thereto. The signal transmitting device 800 and the signal transmitting device 900 in the embodiments of the present invention may further include other components or modules, and the specific details of these components or modules can be found in the relevant technologies.
[0133] Furthermore, for convenience, Figures 8 and 9 only show the connection relationships or signal directions between each component or module; however, various related technologies such as bus connections may be used as can be understood by those skilled in the art. The above-mentioned components or modules may be implemented by hardware such as processors, memory devices, transmitters, and receivers, but the implementation of the present invention is not limited thereto.
[0134] According to an embodiment of the present invention, by determining the transmission power of the transfer signal and / or generated signal using a transceiver, the transceiver can perform power control when it is necessary to transmit the transfer signal and / or generated signal simultaneously. This avoids power limitations and improves the overall transmission efficiency and throughput of the network.
[0135] <Example of the third side> In embodiments of the present invention, a transceiver / third device is provided, which may be, for example, a network device or a terminal device, or one or more components or assemblies located on a network device or terminal device. The transceiver may include a signal transmitting device as described in the embodiments of the second aspect. The third device may include an information transmitting device as described in the embodiments of the second aspect.
[0136] Figure 10 shows a transporter / third device in an embodiment of the present invention. As shown in Figure 10, the transporter / third device 1000 may include a processor 1010 and a memory unit 1020, the memory unit 1020 being connected to the processor 1010. The memory unit 1020 can store various data, and can also store a program 1030 for information processing, and can execute the program 1030 under the control of the processor 1010. Note that this figure is merely illustrative, and telecommunication functions or other functions may be realized by supplementing or substituting this configuration with other types of configurations.
[0137] In one implementation, all or part of the functions of the signal transmitting device / information transmitting device may be integrated into the processor 1010. For example, the processor 1010 may be configured as follows: namely, to determine the transmission power of the first signal and / or the transmission power of the second signal, and to transmit or not transmit the first signal and / or the second signal; and / or to determine the transmission power of the transfer signal and / or the generated signal, and to transmit or not transmit the transfer signal, and to transmit or not transmit the generated signal.
[0138] Alternatively, the processor 1010 may be configured as follows: it transmits first instruction information and / or second instruction information, the first instruction information is used to specify parameters relating to the transmission power of the first signal, and the second instruction information is used to specify parameters relating to the transmission power of the second signal.
[0139] In another implementation, the signal transmitting device / information transmitting device may be configured separately from the processor 1010. For example, the signal transmitting device / information transmitting device may be configured as a chip connected to the processor 1010, and all or part of the functions of the signal transmitting device may be realized by the control of the processor 1010.
[0140] As shown in Figure 10, the processor 1010 may be referred to as a controller or operation control, and may include a microprocessor or other processing unit and / or logic unit, and the processor 1010 can receive inputs and control the operation of each component of the transfer unit 1000.
[0141] Among these, the memory unit 1020 may be one or more of, for example, a buffer, fresh memory, HDD, movable medium, volatile memory, non-volatile memory, or other suitable devices, and can store various data and also store programs relating to the execution of information, and the processor 1010 can realize the storage or processing of information by executing the program stored in the memory unit 1020. Note that the functions of the other components are similar to those of conventional devices, so a detailed explanation of them is omitted here. Each component of the transferr or third device 1000 may be realized by dedicated hardware, firmware, software, or a combination thereof, but all of them are within the scope of the present invention.
[0142] Furthermore, as shown in Figure 10, the transceiver or third device 1000 may also include a transceiver 1040 and an antenna 1050, etc. Since the functions of these components are similar to those in the prior art, a detailed explanation is omitted here. Note that the transceiver 1000 does not need to include all the components shown in Figure 10, and the transceiver or third device 1000 may also include components not shown in Figure 10, for which prior art can be referenced.
[0143] According to an embodiment of the present invention, by determining the transmission power of the transfer signal and / or generated signal using a transceiver, the transceiver can perform power control when it is necessary to transmit the transfer signal and / or generated signal simultaneously. This avoids power limitations and improves the overall transmission efficiency and throughput of the network.
[0144] <Example of the fourth side> An embodiment of the present invention provides a communication system which includes a transporter as described in the fourth embodiment.
[0145] For example, the configuration of the communication system can be seen in Figure 1, which shows that the communication system 100 includes a first device 101, a transceiver 102, and a second device 103. For convenience, Figure 1 uses one first device, one transceiver, and one second device as an example, but the embodiments of the present invention are not limited thereto.
