Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a structural diagram of an uplink transmission system according to an embodiment of the present invention, and as shown in fig. 1, the uplink transmission system includes a mobile communication terminal 11 and a network side device 12, where the mobile communication terminal 11 may be a ue (user equipment), for example: the terminal side Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the Mobile communication terminal 11 is not limited in the embodiments of the present invention. The network side device 12 may be a 5G network side device (e.g., a gNB, a 5G NR NB), or may be a 4G network side device (e.g., an eNB), or may be a 3G network side device (e.g., an NB), and the like, and it should be noted that a specific type of the network side device 12 is not limited in this embodiment of the present invention.
It should be noted that the specific functions of the mobile communication terminal 11 and the network side device 12 will be described in detail through a plurality of embodiments below.
Referring to fig. 2, fig. 2 is a flowchart of an uplink transmission method according to an embodiment of the present invention, and as shown in fig. 2, the uplink transmission method includes the following steps:
step 201, receiving at least one spatial transmission characteristic parameter indication sent by a network side device.
When the network side device notifies the mobile communication terminal to perform uplink transmission, the network side device needs to send at least one spatial transmission characteristic parameter indication, so that the mobile communication terminal can receive the at least one spatial transmission characteristic parameter indication sent by the network side device.
The indication of the spatial transmission characteristic parameter refers to an indication of the spatial transmission characteristic parameter used by the network side device for the mobile communication terminal. The spatial transmission characteristic parameter indication may include at least one of an uplink beam indication or a precoding matrix indication, and accordingly, the spatial transmission characteristic parameter may include at least one of an uplink beam or a precoding matrix.
For convenience of understanding, in the embodiments of the present invention, the spatial transmission characteristic parameter indication is specifically described as an uplink beam indication. Correspondingly, for the case that the spatial transmission characteristic parameter indication is the precoding matrix indication, the spatial transmission characteristic parameter indication can be implemented by referring to the uplink beam indication, and the same beneficial effects are achieved, and the repetition is avoided, which is not described herein again.
In the embodiment of the present invention, the uplink beam indication may include at least one of a SRI (Sounding-Reference-Signal Resource Index, uplink channel state Sounding pilot) or a CRI (CSI-RS Resource Index, downlink channel state Sounding pilot).
Wherein, in case of symmetry existing in the network, the CRI may be used to implicitly indicate the corresponding uplink beam information.
The data to be transmitted in uplink transmission according to the embodiment of the present invention includes at least one data stream, that is, the embodiment of the present invention is suitable for uplink transmission of one data stream (referred to as "single stream transmission") as well as uplink transmission of two or more data streams (referred to as "multi-stream transmission").
The number of uplink beam indicators sent by the network side device should be considered as the number of data streams, and specifically, the at least one uplink beam indicator sent by the network side device includes at least one uplink beam indicator of each data stream.
In the embodiment of the present invention, the network side device is not limited to only sending at least one uplink beam indication, and may also send other reference data or reference information. The reference data or reference information is beneficial to assist the mobile communication terminal to select the target uplink beam, or becomes a condition for the mobile communication terminal to select the target uplink beam to refer to, and the like.
Step 202, selecting a target spatial transmission characteristic parameter based on a measurement result of signal strength corresponding to the spatial transmission characteristic parameter indicated by the spatial transmission characteristic parameter, where the target spatial transmission characteristic parameter is the spatial transmission characteristic parameter indicated by the spatial transmission characteristic parameter, or is a spatial transmission characteristic parameter other than the spatial transmission characteristic parameter indicated by the spatial transmission characteristic parameter.
In the embodiment of the present invention, the mobile communication terminal may select the target uplink beam based on a measurement result of the signal intensity corresponding to the uplink beam indicated by the uplink beam. The target uplink beam selected by the mobile communication terminal may be the uplink beam indicated by the uplink beam in step 201, or may be an uplink beam other than the uplink beam indicated by the uplink beam. For example, if the uplink beam signal strength indicated by the uplink beam is better, the target uplink beam is generally the uplink beam indicated by the uplink beam; if the uplink beam indicated by the uplink beam has poor signal strength, the target uplink beam may be an uplink beam other than the uplink beam indicated by the uplink beam.
Optionally, the uplink transmission method according to the embodiment of the present invention may further include:
the mobile communication terminal measures the signal intensity corresponding to the uplink beam indicated by the uplink beam.
The measurement mode of the signal strength corresponding to the uplink beam indicated by the uplink beam may include, but is not limited to, any one of the following:
measuring the signal intensity corresponding to the uplink wave beam indicated by the uplink wave beam according to the received signal intensity indicator RSSI; alternatively, the first and second electrodes may be,
measuring the signal intensity corresponding to the uplink wave beam indicated by the uplink wave beam according to the echo; alternatively, the first and second electrodes may be,
and measuring the Signal intensity corresponding to the uplink beam indicated by the uplink beam according to a Reference Signal (RS) sent by the network side equipment.
Since the above-mentioned measuring methods can be realized by the prior art, they are not specifically described.
By measuring the signal strength corresponding to the uplink beam indicated by the uplink beam, the mobile communication terminal may obtain a measurement result of the signal strength corresponding to the uplink beam indicated by the uplink beam, where the measurement result may directly or indirectly reflect whether the uplink beam indicated by the uplink beam has a signal blocked or not, or may directly or indirectly reflect whether the signal strength of the uplink beam indicated by the uplink beam satisfies an uplink transmission requirement or not.
As uplink transmission is transmission of at least one data stream, accordingly, selecting a target uplink beam in the embodiment of the present invention may be selecting a target uplink beam of each data stream.
Of course, for the case of multi-stream transmission, when the signal strength corresponding to the uplink beam indicated by the uplink beam of the target data stream is poor, a manner of stream-down transmission, that is, discarding the target data stream, may also be adopted. This mode will be specifically described by way of examples which follow.
It should be noted that the above embodiment is also applicable to the case where the spatial transmission characteristic parameter indication is a precoding matrix indication.
Optionally, the network side device may further configure a PRB (Physical Resource Block) granularity that allows the mobile communication terminal to select the target uplink beam. Specifically, the network side device configures the number of PRBs included in the PRB set for the mobile communication terminal, so that the mobile communication terminal can select a corresponding target uplink beam on each PRB for uplink transmission.
Further, the step of configuring, by the network side device, the number of PRBs included in the physical resource block PRB set for the mobile communication terminal includes:
configuring the number of PRBs contained in a PRB set for the mobile communication terminal through high-level signaling; alternatively, the first and second electrodes may be,
allocating the number of PRBs contained in a PRB set for the mobile communication terminal through physical layer signaling; alternatively, the first and second electrodes may be,
and configuring the number of PRBs contained in the PRB set for the mobile communication terminal in a mode of combining high-layer signaling and physical layer signaling.
Here, the network side device configures the number of PRBs for the mobile communication terminal, which may be performed through a higher layer signaling, or may be performed through a physical layer signaling, or may be performed through a combination of a higher layer signaling and a physical layer signaling.
For the combination of the higher layer signaling and the physical layer signaling, the number of PRBs may be limited to a set by the higher layer signaling, and then further indicated by the physical layer signaling.
Since the mobile communication terminal selects the target uplink beam according to the PRB set granularity, which can be implemented by the prior art, this is not described in detail.
It should be noted that the above embodiment is also applicable to the case where the spatial transmission characteristic parameter indication is a precoding matrix indication.
And 203, performing uplink transmission by using the target space transmission characteristic parameters.
In this step, the mobile communication terminal may perform uplink transmission using the target spatial transmission characteristic parameter selected in step 202.
Accordingly, the uplink transmission using the target spatial transmission characteristic parameter in the embodiment of the present invention may be uplink transmission using each data stream using the target spatial transmission characteristic parameter of each data stream.
In the embodiment of the present invention, through the above steps, the mobile communication terminal may select the target spatial transmission characteristic parameter for uplink transmission based on the measurement result of the signal strength corresponding to the spatial transmission characteristic parameter. Therefore, the embodiment of the invention can effectively avoid the problem of uplink transmission failure caused by the antenna being shielded, thereby reducing the uplink transmission failure rate.
In order to make the uplink transmission method according to the embodiment of the present invention easier to understand, the following description will respectively exemplify a plurality of embodiments by taking the spatial transmission characteristic parameter indication as the uplink beam indication.
One embodiment is as follows:
the method comprises the steps that network side equipment sends an uplink beam indication set of each data stream, and a mobile communication terminal receives the uplink beam indication set of each data stream sent by the network side equipment, wherein the uplink beam indication set of each data stream comprises at least two uplink beam indications.
The mobile communication terminal selects an uplink beam from an uplink beam set of an uplink beam indication set of a target data stream as a target uplink beam of the target data stream, wherein the target data stream is one data stream in each data stream.
Further, the mobile communication terminal selects an uplink beam with the optimal signal strength from the uplink beam set of the uplink beam indication set of the target data stream as the target uplink beam of the target data stream.
The present embodiment is applicable to both single-stream transmission and multi-stream transmission, taking single-stream transmission as an example, as shown in fig. 3, the network side notifies the mobile communication terminal to perform single-stream transmission, and sends two SRIs (beam 1 and beam 7), and the mobile communication terminal selects a corresponding beam from beam 1 and beam 7 for uplink transmission based on the measurement results of the signal strengths of beam 1 and beam 7, for example, according to downlink measurement.
For example, if the signal strength of beam 1 and beam 7 both meet the uplink transmission requirement, the mobile communication terminal may arbitrarily select one of the beams for uplink transmission; if the signal intensity of the beam 1 is better than that of the beam 7, the mobile communication terminal can select the beam 1 with the optimal signal intensity to carry out uplink transmission; if the signal intensity of the beam 1 can not meet the uplink transmission requirement, the mobile communication terminal selects the beam 7 for uplink transmission.
Through the embodiment, the mobile communication terminal can autonomously select the beam for uplink transmission, and can effectively resist antenna shielding and channel change and cannot feed back in time.
The second embodiment:
the network side equipment sends the uplink beam indication of each data flow and the threshold value of each data flow, and the mobile communication terminal receives the uplink beam indication and the threshold value of each data flow sent by the network side equipment.
If the uplink beam signal strength indicated by the uplink beam of the target data stream is less than or equal to the threshold value of the target data stream, the mobile communication terminal selects uplink beams other than the uplink beam indicated by the uplink beam of each data stream as the target uplink beam of the target data stream, wherein the target data stream is one of the data streams.
Further, if the uplink beam signal strength indicated by the uplink beam of the target data stream is less than or equal to the threshold value of the target data stream, the mobile communication terminal selects an uplink beam with the optimal signal strength from uplink beams other than the uplink beam indicated by the uplink beam of each data stream as the target uplink beam of the target data stream.
The present embodiment is applicable to both single-stream transmission and multi-stream transmission, taking single-stream transmission as an example, as shown in fig. 4, a network side notifies a mobile communication terminal to perform single-stream transmission, and sends an SRI (beam 1), and the network side configures a threshold 1 for the mobile communication terminal. The mobile communication terminal finds that the Signal strength of the beam 1 is less than or equal to the threshold value 1 by RSSI or echo measurement or RSRP (Reference Signal Receiving Power) of the RS, and the mobile communication terminal automatically switches the beam for uplink transmission to a beam other than the beam 1, for example, the beam 6.
Through the embodiment, the mobile communication terminal can autonomously switch the beam of uplink transmission when the antenna is shielded, and can effectively resist the antenna shielding and channel change and cannot feed back in time.
The third embodiment:
the method comprises the steps that a network side device sends a main uplink beam indication of each data flow, an alternative uplink beam indication set of each data flow and a threshold value of each data flow, and a mobile communication terminal receives the main uplink beam indication, the alternative uplink beam indication set and the threshold value of each data flow sent by the network side device. Wherein the alternative uplink beam indication set comprises at least one alternative uplink beam indication.
If the uplink beam signal strength indicated by the main uplink beam of the target data stream is less than or equal to the threshold value of the target data stream, the mobile communication terminal selects an alternative uplink beam from an alternative uplink beam set of an alternative uplink beam indication set of the target data stream as the target uplink beam of the target data stream, wherein the target data stream is one data stream of the data streams.
Further, if the uplink beam signal strength indicated by the main uplink beam of the target data stream is less than or equal to the threshold value of the target data stream, the mobile communication terminal selects an alternative uplink beam with the optimal signal strength from the alternative uplink beam set of the alternative uplink beam indication set of the target data stream as the target uplink beam of the target data stream.
The present embodiment is applicable to both single-stream transmission and multi-stream transmission, taking single-stream transmission as an example, as shown in fig. 5, a network side device notifies a mobile communication terminal to perform single-stream transmission, and the network side device indicates two SRIs (beam 1 and beam 7) to the mobile communication terminal, where the beam 1 is a main beam, the beam 7 is an alternative beam, and the network side device configures a threshold 2 for the mobile communication terminal. The mobile communication terminal finds that the signal strength of the main beam 1 is less than or equal to the threshold value 2 through RSSI, RSRP or echo measurement, and the mobile communication terminal can automatically switch the beam of the uplink transmission from the beam 1 to the beam 7.
Through the embodiment, the mobile communication terminal can autonomously switch the beam of uplink transmission when the antenna is shielded, and can effectively resist the antenna shielding and channel change and cannot feed back in time.
The fourth embodiment:
the mobile communication terminal receives the uplink beam indication and the threshold value of each data flow sent by the network side equipment.
And if the uplink beam signal strength indicated by the uplink beam of the target data stream is less than or equal to the threshold value of the target data stream, selecting uplink beams except the uplink beam indicated by the uplink beam of the target data stream in the uplink beam indications of the data streams as target uplink beams, wherein the target data stream is one data stream in the data streams.
And performing uplink transmission of data streams except the target data stream by using the target uplink beam.
The embodiment is applicable to multi-stream transmission, and when the mobile communication terminal detects that the signal strength of a part of uplink beams in the mobile communication terminal is less than or equal to respective corresponding threshold values, the mobile communication terminal may revert to less stream transmission from multi-stream transmission, including single stream transmission.
Through the embodiment, the mobile communication terminal can autonomously select the wave beam with good signal intensity to transmit the corresponding data stream when the antenna is shielded, and can effectively resist the antenna shielding and the channel change and cannot feed back in time.
The fifth embodiment:
the network side equipment sends the uplink beam indication of each data flow and the threshold value of each data flow, and the mobile communication terminal receives the uplink beam indication and the threshold value of each data flow sent by the network side equipment.
And if the uplink beam signal strength indicated by the uplink beam of the target data stream is less than or equal to the threshold value of the target data stream, selecting the uplink beam except the uplink beam indicated by the uplink beam of the target data stream in the uplink beam indication of each data stream as the target uplink beam of the target data stream, wherein the target data stream is one data stream in each data stream.
And performing uplink transmission of the target data stream by using the target uplink beam.
The embodiment is applicable to multiflow transmission, and when the mobile communication terminal detects that the signal strength of a part of uplink beams in the multiflow transmission mode is less than or equal to the respective corresponding threshold value, the mobile communication terminal still performs uplink transmission according to the multiflow transmission mode, but the mobile communication terminal can autonomously determine the mapping order and the mapping rule of multiflow between layers.
Through the embodiment, the mobile communication terminal can autonomously determine the mapping sequence and the mapping rule of multiple streams among layers when an antenna is shielded, and selects other beams with good signal strength for the data stream with poor signal strength to transmit the corresponding data stream, so that the antenna shielding and channel change can be effectively resisted and the feedback can not be carried out in time.
The above is an example of various implementation manners of the embodiment of the present invention, and the above example fully illustrates that the mobile communication terminal may select the target spatial transmission characteristic parameter for uplink transmission based on the measurement result of the signal strength corresponding to the spatial transmission characteristic parameter, so that the problem of uplink transmission failure caused by the antenna being blocked can be effectively avoided, and the uplink transmission failure rate can be reduced.
