The transmission processing method provided by the embodiment of the application is described in detail below by means of some embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 3, a transmission processing method according to an embodiment of the present application includes:
step 301, a relay device configures relay transmission parameters; wherein the configuration is based on at least one of the following information:
the network equipment transmits transmission parameter control information to the relay equipment, wherein the transmission parameter control information is determined by the network equipment according to the noise coefficient related information of the relay equipment;
A limitation condition of the relay transmission parameter;
the association relation between the relay transmission parameters and the transmission resources;
and the effective time of the relay transmission parameter.
Thus, according to the step 301, the relay device may configure the relay transmission parameter based on at least one of the transmission parameter control information sent by the network device and determined by the noise coefficient related information of the relay device, the limitation condition of the relay transmission parameter, the association relationship between the relay transmission parameter and the transmission resource, and the effective time of the relay transmission parameter, so as to achieve more reasonable amplification of the signal by the relay device.
The relay device realizes the amplifying function of the signal through the arranged amplifier, and the relay transmission parameter is a parameter related to signal amplification.
Optionally, in this embodiment, the relay transmission parameter includes at least one of:
magnification;
transmitting the beam;
whether the amplifier is enabled.
The amplification factor is that the relay device amplifies signals, and the amplification factor configured by the relay device comprises at least one of the following: the value of the magnification, the maximum value of the magnification, the minimum value of the magnification, the range value of the magnification and the adjustment value of the magnification. Optionally, the magnification has an association with the transmission beam (beam), so that the magnification configured by the relay device will be applied to the transmission beam having an association with the magnification.
Wherein the transmission beam, i.e. the beam that the relay device expects or does not expect to use for the amplified signal transmission. The transmission beam is at least an uplink transmission beam between the network device and the relay device. Optionally, the transmission beam has an association with the amplification factor, so that after the relay device amplifies the signal based on the amplification factor, the relay device transmits the signal only on the transmission beam having an association with the amplification factor.
And whether the amplifier is enabled or not can also be understood as whether the relay device amplifies the signal or not. Optionally, whether the amplifier is enabled has an association with the transmission beam, so that the relay device determines for the transmission beam whether to amplify a signal on the transmission beam.
In addition, in this embodiment, since the transmission parameter control information is determined by the network device according to the noise coefficient related information of the relay device, if the relay device configures the relay transmission parameter based on the transmission parameter control information, the configured relay transmission parameter can be made to meet the network device requirement in response to the control of the network device, so that the interference of the amplified uplink signal to the network device (i.e. the increment of the noise level of the control network device) is reduced, and the coverage area of the uplink signal is maintained.
Wherein the noise figure related information is obtained by the network device according to at least one of the following modes:
predefining;
reporting by the relay equipment;
noise level of the receiver.
Here, the noise level of the receiver may be processed to obtain noise figure related value information. The noise figure related information used when the network device determines the transmission parameter control information may be at least one of predefined noise figure related information, noise figure related information reported by the relay device, or noise figure related information resulting from the noise level of the receiver.
Optionally, in this embodiment, before step 301, the method further includes:
the relay device transmits the noise figure related information to the network device.
That is, the relay device transmits noise figure related information to the network device so that the network device determines transmission parameter control information based on the noise figure related information. For example, the relay device sends capability (capability) information to the network device, where the capability information carries noise figure related information.
Optionally, in this embodiment, the noise figure related information includes at least one of:
Correlation value information of noise coefficients;
class information of noise coefficients;
the kind information of the relay device.
Here, the related value information of the noise coefficient includes at least one of: the value of the noise coefficient, the maximum value of the noise coefficient, the minimum value of the noise coefficient, the range value of the noise coefficient and the adjustment value of the noise coefficient. The noise level information is obtained by classifying the noise level according to the value of the noise level, so that the noise level is roughly reflected, and exposure of the specific noise level can be avoided when the noise level information is used. The type information of the relay device may also be understood as level information of the relay device, where the type information of the relay device is associated with related value information of the noise figure to roughly reflect the noise figure, and exposure to a specific noise figure value can be avoided when the type information of the relay device is used.
In this embodiment, the transmission parameter control information is used to guide the configuration of the relay transmission parameter, for example, the transmission parameter control information indicates the value or the value range of the relay transmission parameter.
For example, the network device determines transmission parameter control information according to the predefined related value information of the noise figure (such as the maximum value A1 of the noise figure), where the transmission parameter control information indicates that the amplification factor is smaller than A1 (i.e. the amplification factor corresponding to the maximum value A1 of the noise figure), and sends the transmission parameter control information to the relay device, so that the relay device may configure the amplification factor to be a2, where a2 is smaller than A1. Or, the network device determines transmission parameter control information according to the related value information of the noise coefficient (such as the value A2 of the noise coefficient) reported by the relay device, where the transmission parameter control information indicates that the amplification factor is a3 (i.e. the amplification factor corresponding to the value A2 of the noise coefficient), and sends the transmission parameter control information to the relay device, so that the relay device can configure the amplification factor to be a3. Or, the network device obtains the noise level of the receiver by measuring, and further obtains the related value information of the noise coefficient (such as the range value A3-A4 of the noise coefficient), determines the transmission parameter control information, where the transmission parameter control information indicates that the amplification factor is greater than A4 (i.e. the amplification factor corresponding to the value A3 of the noise coefficient) and less than a5 (i.e. the amplification factor corresponding to the value A4 of the noise coefficient), and sends the transmission parameter control information to the relay device, so that the relay device may configure the amplification factor to be a6, where a6 is greater than A4 and less than a5.
Of course, in the process of determining the transmission parameter control information according to the noise coefficient related information, the network device may combine the noise coefficient related information and the transmission path loss (path) to determine the transmission parameter control information; alternatively, the network device may also determine transmission parameter control information in combination with noise figure related information, pathloss and amplification factor, where the transmission parameter control information directs the configuration of other parameters than amplification factor, such as a desired or undesired transmission beam.
The path at least comprises the path loss between the network equipment and the relay equipment, and the path loss can be measured by the network equipment or measured and reported by the relay equipment. Alternatively, the pathloss may have an association with the transmission beam, that is, the network device or the relay device measures for the transmission beam to obtain the corresponding pathloss. In the case where the network device needs to determine the transmission parameter control information in combination with the amplification factor, the amplification factor may be indicated in advance by the network device, which is notified by the operation and maintenance management device (Operation Administration and Maintenance, OAM), which is reported by the relay device.
Optionally, in this embodiment, the limitation condition includes at least one of:
The amplification factor and the transmission path loss meet a first condition;
the amplification factor, transmission path loss, and noise figure satisfy the second condition.
Wherein the first condition may be that the value of G-PL is less than or equal to a first threshold; the second condition may be that the value of nf+g-PL is less than or equal to a second threshold. G denotes the amplification factor, PL denotes the transmission path loss, and NF denotes the noise figure. Here, the first threshold value and the second threshold value may be predefined or indicated by the network device.
It should also be appreciated that the constraints may be predefined or indicated by the network device.
Optionally, the relay device configures the relay transmission parameter based on the constraint condition, including at least one of:
the relay device configures the amplification factor in the relay transmission parameter to be a desired value;
the relay device configures a transmission beam in the relay transmission parameters to be a desired beam.
That is, the relay device preferably configures the amplification factor to a desired value and/or preferably configures the transmission beam to a desired beam when configuring the relay transmission parameter based on the constraint condition, and then configures other parameters.
Here, the desired value of the magnification, the desired beam, may be a desire of the relay device. Wherein, in case the limitation condition is an indication of the network device, the relay device may report the desired value of the amplification factor and/or the desired beam to the network device, so that the network device controls the configuration of the relay transmission parameters by sending the limitation condition to the relay device.
Of course, the relay device configures the relay transmission parameters based on the constraint conditions, so that the configured relay transmission parameters maximally meet the constraint conditions, however, it is not excluded that the configured relay transmission parameters still cannot meet the constraint conditions. Thus, optionally, after the relay device configures the relay transmission parameter based on the constraint condition, the relay device further includes:
in the case where the configured relay transmission parameter does not satisfy the constraint condition, the relay device performs at least one of:
disabling the amplifier;
transmitting configuration failure information to the network equipment;
stopping amplification of the transmission signal on the first beam;
transmitting beam information of the second beam to the network device;
the first beam and the second beam are beams which do not meet the limiting condition after configuration.
Here, the configuration failure information indicates that the current relay transmission parameter configuration does not satisfy the constraint. The feedback of the configuration failure information and/or the beam information of the second beam to the network device can assist the network device in deciding at least one of the following: how to configure relay transmission parameters, how to schedule resources, and how to control relay devices.
Optionally, in this embodiment, before step 301, the method further includes:
the relay device receives first indication information and/or second indication information of the network device;
the first indication information is used for indicating the relay transmission parameters;
the second indication information is used for indicating transmission resources with association relation with the relay transmission parameters.
In this way, the relay device can configure the relay transmission parameter based further on the effective time of the relay transmission parameter according to the first indication information. For example, the effective time corresponding to the different relay transmission parameters (such as the amplification factor) indicated by the default first indication information is not overlapped; alternatively, the first indication information indicates a relay transmission parameter and an effective time thereof.
Of course, the relay device can configure the relay transmission parameters by itself based on the effective time of the relay transmission parameters without a network device indication. For example, the effective times of the predefined magnifications do not overlap and are each 1 hour, the relay device configures a plurality of magnifications, and then the signal is amplified sequentially at each hour using different magnifications.
The relay device configures relay transmission parameters according to the first indication information and/or the second indication information based on the association relation between the relay transmission parameters and the transmission resources. For example, the association relation between the relay transmission parameters and the transmission resources is predefined, and for the case of only receiving the first indication information, the relay transmission parameters (such as the amplification factor) of the corresponding transmission resources are configured according to the association relation between the predefined relay transmission parameters and the transmission resources; or, for the case of receiving the first indication information and the second indication information, configuring the relay transmission parameters (such as amplification factor) of the corresponding transmission resources according to the association relation between the relay transmission parameters indicated by the second indication information and the transmission resources; alternatively, for the case where only the second indication information is received, a relay transmission parameter (e.g., a magnification) corresponding to the transmission resource is configured.
Of course, the relay device can configure the relay transmission parameter based on the association relationship between the relay transmission parameter and the transmission resource by itself without the network device indication, for example, the association relationship between the amplification factor and the transmission resource is predefined, and if the relay device configures multiple amplification factors, the multiple amplification factors are applied to the transmission resources corresponding to each other according to the association relationship between the predefined amplification factor and the transmission resource.
In this embodiment, the transmission resources include time domain resources and/or frequency domain resources. For example, the first indication information indicates multiple magnifications, and the second indication information indicates time domain resources and/or frequency domain resources associated with the multiple magnifications, so that the relay device can configure the magnifications used on the specific time domain resources and/or frequency domain resources, that is, the magnifications are only effective on the associated time domain resources and/or frequency domain resources.
Optionally, in this embodiment, the effective times of the multiple magnifications of the relay device configuration do not overlap.
Therefore, different amplification factors can be effective in different time periods, and the situation that the amplification factors are mixed is avoided. For example, the validity times of the different magnifications are predefined not to overlap, and the relay device receives the first indication information indicating a new magnification if the validity time of the magnification is not expired. Of course, the effective times of other relay transmission parameters may not overlap, and will not be described in detail herein.
It should be further noted that, in this embodiment, the relay device configures the relay transmission parameters, and the effective times of the multiple configured magnifications overlap, so optionally, after step 301, the embodiment further includes:
in the case where there is an overlap in the effective time of the plurality of configured magnifications, the relay device selects one magnification within the overlap time.
The selection mode may be selected randomly from the plurality of magnifications, or may be selected according to a preset rule. Here, the preset rule includes at least one of:
adopting the latest magnification;
adopting the minimum magnification;
the maximum magnification is used.
Optionally, in this embodiment, after the relay device selects one of the amplification factors in the overlapping time, the method further includes:
and the relay equipment reports the selected magnification to the network equipment.
That is, after selecting one of the multiple magnifications with overlapping effective time, the relay device reports the multiple to the network device, so that the network device can learn the magnification and assist the network device in scheduling.
Of course, when the number of other relay transmission parameters is plural, the selection and reporting processes may be performed as in the case of the above-mentioned amplification factors, and will not be described here again.
Optionally, in this embodiment, the magnification includes at least one of: uplink amplification factor; downstream amplification.
In this way, the first indication information and the second indication information may also indicate the amplification factor independently for uplink and downlink, which is not described herein.
