Abstract

Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an indicating method and an indicating device for transmission powers, and a network node.
Background
As shown in fig. 1, 3GPP (third generation partnership project) introduces a self-backhaul technology, replaces optical fiber backhaul with high-frequency air interface transmission, and can transmit data back to a station with optical fiber transmission capability through a multi-hop link. For example, base station B and base station C transmit data back to base station a with optical fiber transmission capability via a backhaul link.
The method of allocating resources on the backhaul link and the access link may be divided into FDM (frequency division multiplexing), TDM (time division multiplexing), and SDM (space division multiplexing). Fig. 2 shows a schematic diagram of a backhaul link and an access link TDM; fig. 3 shows a schematic diagram of a backhaul link and an access link FDM; fig. 4 is a schematic diagram of the backhaul link and the access link SDM.
In order to ensure that resources are fully utilized, when an IAB (relay station) transmits back or sends back, the transmission of a BH (back link) and the transmission of a link corresponding to the IAB serving UE (terminal served by the relay station) can be performed simultaneously, that is, Space Division Multiplexing (SDM) of the IABbackhaul and the access link.
In the case of IAB based transmission, at least two cases are included:
case the IAB and terminal are transmitting upstream simultaneously.
For the uplink transmission of the IAB backhaul and the uplink transmission of the terminal, the transmission modes of TDM, FDM, and SDM may be selected.
When TDM transmission is selected, uplink transmission (i.e., IAB-BH-UL) returned by the IAB may select the maximum transmission power according to the IAB base station. At this time, more streams and higher modulation orders can be provided through higher power transmission, so that the transmission resources of the backhaul link can be fully utilized. Therefore, when the access link and the backhaul link perform TDM transmission, a full power transmission mode may be considered.
When FDM transmission is selected, the IAB may select an uplink power control mode similar to that of the terminal to perform uplink transmission in order to prevent the terminal from being blocked.
When SDM transmission is selected, similar to FDM reception, in order to protect uplink transmission of the terminal, the sending rate of uplink transmission (i.e., IAB-BH-UL) returned by the IAB cannot be too high, and therefore the IAB needs to transmit in a manner similar to uplink power control of the terminal.
Case two: the IAB downlink transmission and the access link are multiplexed.
For uplink transmission returned by the IAB and downlink transmission of the IAB to the terminal, the transmission modes of TDM, FDM, and SDM may be adopted.
When the TDM transmission is selected, the uplink transmission (i.e., IAB-BH-UL) returned by the IAB and the downlink transmission (i.e., IAB-UE-DL) of the terminal by the IAB can be respectively transmitted with full power.
When FDM transmission is selected, the downlink transmission (i.e., IAB-UE-DL) from the IAB to the terminal may be sent with full power. If the uplink transmission (i.e. IAB-BH-UL) returned by the IAB continues to transmit according to the uplink power control, the difference between the sending power of the downlink transmission from the IAB to the terminal and the power of the uplink transmission returned by the IAB is more than 6dB during FDM, which results in hard support of hardware.
When SDM transmission is selected, in order to ensure that the IAB can not configure full power transmission for uplink transmission returned by the IAB for downlink transmission to the terminal, uplink transmission can be performed according to an uplink power control mode.
Based on the above analysis, the IAB needs to support two actions that can perform full power transmission and power control transmission on the backhaul uplink for the above two cases. However, the uplink transmission scheme supported by the existing protocol is only transmission based on power control, and does not support full power transmission. Meanwhile, it is difficult for the IAB to directly indicate what specific transmission power is because of the problem of the transmission power of the base station. However, it is difficult to maximize the transmission power by the closed-loop power control based on the power control method. However, the existing uplink scheduling grant signaling only supports power adjustment based on TPC (transmit power control).

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 5, an embodiment of the present invention provides methods for indicating transmission power, which are applied to a th network node, and include:
Here, the th network node may be a base station gNB (5G base station), or may be a network node with backhaul capability such as a relay station IAB.
For example, the base station transmits th indication information to IAB _1(IAB _1 is an IAB connected to the base station), and the th indication information indicates a transmission power scheme used for transmission of IAB _ 1. for example, IAB _1(IAB _1 is an IAB connected to the base station) transmits th indication information to IAB _2(IAB _2 is a sub-IAB connected to IAB _ 1), and the th indication information indicates a transmission power scheme used for transmission of IAB _ 2.
As embodiments, the lower -level transmission node of the network node is a backhaul-capable network node, such as a relay station iab, and accordingly, in the case that the lower -level transmission node of the network node is a backhaul-capable network node, the indication information is used to indicate a transmission power mode used by the lower -level transmission node when transmitting on a backhaul link.
Preferably, in the above embodiments of the present invention, the transmission power method used by the lower level transmission node of the th network node for transmission includes:
a full power mode (i.e., a full power mode is used for transmission, or a full power mode is used for transmission); and the number of the first and second groups,
a power control based scheme (i.e., a scheme based on power control is used for transmission, or a scheme using non-full power is used for transmission).
For example, the th indication information occupies 1bit (bit), when the th indication information bit is equal to 1, the th indication information indicates that the next -level transmission node performs transmission in a full power mode, and when the th indication information bit is equal to 0, the th indication information indicates that the next -level transmission node performs transmission in a power control-based mode.
, in the above embodiment of the present invention, step 51 includes:
and sending scheduling authorization information to a lower -level transmission node of the -th network node, wherein the scheduling authorization information comprises the -th indication information.
As embodiments, the network node schedules the lower level transmission node to perform uplink transmission on the backhaul link through the scheduling grant information, and the lower level transmission node performs uplink transmission on the backhaul link in a full power manner or in a manner based on power control according to the indication of the indication information carried by the scheduling grant information.
For example, 1bit information (the 1bit information is the th indication information) is added to a control signaling of the scheduling authorization information, and is used for indicating a transmission power mode when uplink transmission of a lower -level transmission node is scheduled, when the bit is 1, the lower -level transmission node needs to transmit in a power control mode when uplink transmission is performed, and when the bit is 0, the corresponding lower -level transmission node does not need to transmit in the power control mode but adopts a full power mode for transmission (i.e., a transmission mode similar to downlink traffic).
For another example, multiplexing the TPC commands in the existing scheduling grant information, resetting states (e.g., TPC command state X) to indicate that the TPC commands are transmitted in a full power manner, and if the TPC commands are in other states, adjusting and operating in the original TPC manner by the lower -level transmission node.
It should be noted that, the manner based on power control mentioned in the embodiment of the present invention is as follows:
TXP＝10*log10(M)+P0+α*PL+β；
wherein, TXP is the power of uplink transmission determined based on a power control mode, M represents the number of resources occupied by the uplink transmission, P0 represents target receiving power, α represents partial power compensation factors, PL represents path loss, and β represents other parameters.
, in the above embodiment of the present invention, step 51 includes:
in case that resource multiplexing is performed between the transmission link between the lower -level transmission node and the network node and the second transmission link between the terminal and the network node (in case that resource multiplexing is performed between the transmission of the lower -level transmission node, which may also be referred to as the network node, on the transmission link and the transmission of the terminal on the second link), the th indication information is sent to the lower -level transmission node of the network node.
Preferably, the method further comprises:
and determining a transmission power mode used by the lower -level transmission node of the -th network node for transmission according to a multiplexing mode of the -th transmission link and the second transmission link (which can also be referred to as a multiplexing mode of transmission of the lower -level transmission node of the -th network node on the -th transmission link and transmission of the terminal on the second link).
Specifically, the determining, according to the multiplexing manner of the transmission link and the second transmission link, the transmission power manner used when the transmission is performed by the lower -stage transmission node of the network node includes:
when the transmission link and the second transmission link are multiplexed in a time division multiplexing manner, determining that a transmission power manner used for transmission by a lower -stage transmission node of the network node is a full power manner;
and when the th transmission link and the second transmission link are frequency division multiplexing or space division multiplexing, determining that a transmission power mode used by the lower -level transmission node of the network node for transmission is based on a power control mode.
As embodiments, the transmission link is a backhaul link and the second transmission link is an uplink access link.
For example, as shown in fig. 7, the base station (i.e. the th network node) schedules uplink transmission of the backhaul link of the relay station IAB (i.e. the th network node's lower level transmission node) in the second time unit, and at this time, the terminal served by the base station in the time unit is not scheduled to perform uplink transmission, the multiplexing manner of the backhaul link and the uplink access link in the time unit is time division multiplexing.
As shown in fig. 7, in the fourth time unit, in order to ensure the flexibility of backhaul link transmission and simultaneously meet the service transmission requirement of -like terminals, the uplink transmission of the backhaul link adopts a transmission method of frequency division multiplexing, FDM, or space division multiplexing, SDM, with the uplink transmission of other terminals, when the transmission method of frequency division multiplexing, FDM is adopted, the base station configures the relay station IAB to perform uplink transmission by using a power control-based method, so that it is ensured that the service transmission of -like terminals is not affected, and simultaneously the transmission requirement of the backhaul link is met.
As shown in fig. 8, when a base station (i.e., the th network node) schedules a backhaul link of an IAB (i.e., the lower -level transmission node of the th network node), the uplink transmission of the IAB backhaul link and the uplink transmission of a terminal served by the base station perform resource multiplexing, when a TDM multiplexing scheme is adopted, the transmission of the IAB-BH-UL and the transmission of the UE-UL occur at different times, and in order to ensure the transmission quality of the IAB-BH-UL, the base station schedules the IAB to perform uplink transmission on the IAB backhaul link in a full power mode.
In summary, in the method for indicating transmission power provided in the above embodiment of the present invention, the th indication information indicates the transmission power mode used by the lower level transmission node for transmission, so that the lower level transmission node can perform both full power transmission and power control-based transmission, thereby improving the transmission quality of the backhaul link and ensuring the transmission quality of the access link of the terminal.
As shown in fig. 9, an embodiment of the present invention further provides methods for indicating transmission power, which are applied to a second network node, and include:
Here, the second network node may be a main relay station IAB connected to the base station, or may be a sub-IAB connected to the main IAB.
For example, when the second network node is a master IAB connected to a base station, the upper -level transport node of the second network node is a base station gNB (5G base station), and when the second network node is a slave IAB connected to the master IAB, the upper -level transport node of the second network node is an upper -level IAB.
As embodiments, the second network node is a backhaul-capable network node, such as a relay station iab, and in the case that the second network node is a backhaul-capable network node, the second indication information is used to indicate a power transmission manner proposed by the second network node to be used by the second network node for transmission on a backhaul link.
, in the above embodiment of the present invention, after step 91, the method further includes:
and receiving third indication information sent by an upper -level transmission node of the second network node, wherein the third indication information is used for indicating the transmission power mode used by the second network node for transmission, which is determined by the upper -level transmission node.
In other words, the upper class transmission node of the second network node may recognize the proposed transmission power mode thereof or may not recognize the proposed transmission power mode thereof (or may not need to re-schedule other transmission power modes for the second network node under different recognition conditions), which is not limited specifically herein.
Preferably, in the above embodiment of the present invention, the transmission power method used by the second network node for transmission includes:
a full power mode (i.e., a full power mode is used for transmission, or a full power mode is used for transmission); and the number of the first and second groups,
a power control based scheme (i.e., a scheme based on power control is used for transmission, or a scheme using non-full power is used for transmission).
For example, the second indication information occupies 1bit (bit), and when the bit of the second indication information is 1, the second indication information indicates the network node to propose itself to transmit in a full power manner; and when the bit of the second indication information is 0, the second indication information indicates the network node to transmit in a power control-based mode.
It should be noted that, the manner based on power control mentioned in the embodiment of the present invention is as follows:
TXP＝10*log10(M)+P0+α*PL+β；
wherein, TXP is the power of uplink transmission determined based on a power control mode, M represents the number of resources occupied by the uplink transmission, P0 represents target receiving power, α represents partial power compensation factors, PL represents path loss, and β represents other parameters.
, in the above embodiment of the present invention, the step 91 includes:
and sending a scheduling request to an upper -level transmission node of the second network node, where the scheduling request carries the second indication information.
Correspondingly, the receiving of the third indication information sent by the upper -level transport node of the second network node includes:
and receiving scheduling authorization information sent by an upper -level transmission node of the second network node, where the scheduling authorization information carries the third indication information.
As embodiments, when sending a scheduling request to an upper -level transmission node, a second network node carries second indication information in its scheduling request, and after receiving the scheduling request, the upper -level transmission node determines whether to schedule the second network node according to the recommendation of the second network node according to a specific situation, and sends scheduling authorization information to the second network node, and in its scheduling authorization information, may indicate a terminal to transmit in a full power manner or in a power control-based manner.
, in the above embodiment of the present invention, the step 91 includes:
and in the case that the third transmission link between the second network node and the upper -level transmission node and the fourth transmission link between the second network node and the terminal are subjected to resource multiplexing, sending second indication information to the upper -level transmission node of the second network node.
Preferably, the method further comprises:
and determining a transmission power mode used when the second network node is transmitted, which is suggested by the second network node, according to the multiplexing mode of the third transmission link and the fourth transmission link.
Specifically, the determining, according to the multiplexing manner of the third transmission link and the fourth transmission link, the transmission power manner used when the second network node performs transmission, which is suggested by the second network node, includes:
when the multiplexing mode of the third transmission link and the fourth transmission link is time division multiplexing or frequency division multiplexing, determining that the transmission power mode used by the second network node for transmission suggested by the second network node is: a full power mode;
when the multiplexing mode of the third transmission link and the fourth transmission link is space division multiplexing, determining that a transmission power mode used when the second network node performs transmission, which is suggested by the second network node, is: based on the manner of power control.
Preferably, the third transmission link is a backhaul link, and the fourth transmission link is a downlink.
For example, as shown in fig. 10, the base station schedules the IAB for uplink transmission of the backhaul link, the IAB schedules the served terminal for downlink transmission of the traffic, and the two transmissions are resource multiplexed.
As shown in fig. 11, when the TDM multiplexing mode is adopted, the IAB-BH-UL and the UE-DL are transmitted at different times, and the IAB-BH-UL may adopt a full power transmission mode. When FDM transmission is used, the IAB-BH-UL transmission may be sent with full power, and UE-DL transmission may also be sent with full power, but in this case, it is necessary to ensure that the transmission power difference on adjacent frequency resources is within 6 dB. When the SDM transmission mode is adopted, in order to ensure that the downlink of the terminal has enough power for transmission, the IAB-BH-UL transmission adopts a mode based on power control, and the residual power is used for the transmission of UE-DL.
In this case, when the IAB makes an uplink transmission scheduling request, it proposes that the base station transmits with full power or in a power control-based manner when applying for uplink scheduling according to a potential multiplexing manner. And the base station sends the IAB whether to adopt a power control mode or not to the IAB according to the actual situation.
It should be noted that, when the IAB performs the uplink transmission scheduling request, the process of determining the transmission power mode of the IAB-BH-UL according to the possible potential multiplexing mode is as follows:
the base station schedules the IAB to transmit the return link at the time n, and the IAB determines whether the downlink service which needs to be scheduled exists at the time n. If the transmission mode is FDM, the IAB will suggest the base station to adopt the full power transmission mode; if it is SDM, the IAB will suggest the base station to use the transmission mode for power control. If there is no downlink terminal traffic that needs to be transmitted, the transmission mode of TDM is adopted, and at this time, the IAB recommends that the base station adopt a full-power mode for scheduling.
And the base station indicates whether the uplink transmission of the IAB adopts full power transmission or a power control mode through the uplink scheduling authorization according to the scheduling request of the IAB and the actual transmission requirement.
