Specific embodiments of the present disclosure have been shown by way of example in the drawings and will be described in more detail below. These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

According to an aspect of the embodiments of the present disclosure, a method for measuring link path loss is provided, where the method may be applied to an NR unlicensed spectrum access (NR-U), and the method may be applied to a 5G terminal product.

Referring to fig. 1, fig. 1 is a schematic flow chart of a method for measuring link path loss according to an embodiment of the present disclosure.

As shown in fig. 1, the method includes:

s101: information of a sub-band occupied by a base station is acquired.

The link path loss refers to a link path loss caused by a communication link between the base station and the terminal in a data transmission process. The path loss, or propagation loss, refers to the loss generated by the propagation of the electric wave in space, which is caused by the radiation spread of the transmitted power and the propagation characteristics of the channel, and reflects the variation of the average value of the received signal power in the macroscopic range.

The sub-band (RB-set) is a plurality of frequency bands obtained by dividing the entire frequency band (i.e., bandwidth) of one cell. For example, in the unlicensed spectrum, one cell (cell) contains one Carrier (Carrier), and the bandwidth of one Carrier may be 20mhz,40mhz, 8230, 80MHz, and so on. Since contention for access to the channel is required when the NR unlicensed spectrum accesses the channel, the base station needs to perform Listen Before transmit, i.e., LBT (Listen Before Talk), and the basic unit of LBT in the frequency domain is 20MHz, so that one carrier may be divided into multiple sub-bands in units of 20 MHz.

In some embodiments, the subbands may be a set of resource blocks (RB-sets) consisting of contiguous resource blocks. In some embodiments, the information of the sub-band may be the number of sub-bands. E.g., 2 sub-bands, i.e., 40MHz;4 sub-bands, i.e. 80MHz, etc.

In some embodiments, a plurality of the sub-bands may be contiguous.

In some embodiments, a plurality of the sub-bands may be discontinuous.

Then, in this step, obtaining the information of the sub-bands occupied by the base station may be understood as obtaining the number of sub-bands occupied by the base station at a certain transmission time, such as 2 sub-bands.

In other embodiments, the information of the sub-bands may also be represented by a combination x of sub-bands. For example, subband combination 1, i.e., 1 subband, i.e., 20MHz; subband combination 2, i.e. 2 subbands, i.e. 40MHz; the subband combination 3, i.e. 3 subbands, is 60MHz; subband combination 4, i.e. 4 subbands, i.e. 80MHz, etc.

Then, in this step, obtaining the information of the sub-bands occupied by the base station may be understood as obtaining a combination x of the sub-bands occupied by the base station at a certain transmission time, such as sub-band combination 4.

Of course, in other embodiments, the information of the sub-band may also be bandwidth information of the sub-band, such as 80MHz.

In some embodiments, the subband information occupied by the base station is indicated by a common control channel, and the indication may be a bitmap (bitmap), where a bit in the bitmap corresponds to one subband, where a bit of 0 indicates that the subband base station does not contend, and a bit of 1 indicates that the subband base station contends.

In some embodiments, the sub-band occupied by the base station may be understood as a contention by the base station to an unlicensed band (unlicensed band) or a contention to an unlicensed band and a signal transmitted on these channels. S102: and determining an adjustment parameter corresponding to the information of the sub-band according to a preset mapping relation between the information of the sub-band and the adjustment parameter so as to perform power control based on the adjustment parameter.

In the embodiment of the present disclosure, when measuring the link path loss, the difference in energy per resource unit due to the difference in the sub-bands occupied by the base station is fully considered, and the difference is adaptively adjusted by increasing the adjustment parameter, so as to ensure the reliability and accuracy of power control.

In some embodiments, the adjustment parameter may be an offset value, which is an integer and has a unit of dB.

For example: the adjustment parameter is a parameter for adjusting the transmission power of the reference signal. The adjustment parameter may determine an adjustment parameter corresponding to the information of the subband based on experience or experiments, and construct a mapping relationship between the information of the subband and the adjustment parameter.

In other embodiments, the adjustment parameter may also be a P0 value. The P0 value may be composed of a sum of a component parameter P0_ normal _ PUSCH and a component parameter P0_ UE _ PUSCH, and the component parameter may be provided by signaling corresponding to a protocol higher layer parameter. The P0 value definition is detailed in section 7 of 3gpp ts38.213.

With reference to the above example, if the information of the sub-bands is the number of the sub-bands, a mapping relationship between the number of the sub-bands and the adjustment parameter is constructed. That is, the adjustment parameters for the number of different sub-bands are different.

For example, if the number of sub-bands is 1, that is, the base station occupies 1 sub-band (i.e., 20 MHz), the adjustment parameter a for 1 sub-band is determined based on the mapping relationship; if the number of the sub-bands is 2, that is, the base station occupies 2 sub-bands (i.e., 40 MHz), determining an adjustment parameter b corresponding to the 2 sub-bands based on the mapping relationship; if the number of the sub-bands is 3, that is, the base station occupies 3 sub-bands (i.e., 60 MHz), determining an adjustment parameter c for the 3 sub-bands based on the mapping relationship; if the number of the sub-bands is 4, that is, the base station occupies 4 sub-bands (that is, 80 MHz), determining an adjustment parameter d corresponding to the 4 sub-bands based on the mapping relationship; and so on.

In some embodiments, the tuning parameter a is greater than the tuning parameter b; the adjusting parameter b is larger than the adjusting parameter c; the adjustment parameter c is greater than the adjustment parameter d.

In some embodiments, adjustment parameter a is 3dB greater than adjustment parameter b; the adjustment parameter b is 1.7dB greater than the adjustment parameter c; the tuning parameter c is 1.3dB larger than the tuning parameter d.

And if the information of the sub-bands is the combination of the sub-bands, constructing a mapping relation between the combination of the sub-bands and the adjustment parameters. That is, the adjustment parameters for different combinations of subbands are different.

For example, if the combination of the sub-bands is combination 1 of the sub-bands, that is, the base station occupies 1 sub-band (i.e., 20 MHz), the adjustment parameter e of combination 1 of the sub-bands is determined based on the mapping relationship; if the combination of the sub-bands is a combination 2 of the sub-bands, namely the base station occupies 2 sub-bands (namely 40 MHz), determining an adjusting parameter f of the combination 2 of the sub-bands based on the mapping relation; if the combination of sub-bands is a combination of sub-bands 3, that is, the base station occupies 3 sub-bands (i.e., 60 MHz), determining an adjustment parameter g for the combination of sub-bands 3 based on the mapping relationship; if the combination of the sub-bands is the combination 4 of the sub-bands, namely the base station occupies 4 sub-bands (namely 80 MHz), determining an adjustment parameter h of the combination 4 of the sub-bands based on the mapping relation; and so on.

In some embodiments, the tuning parameter e is greater than the tuning parameter f; the adjusting parameter f is larger than the adjusting parameter g; the adjustment parameter g is greater than the adjustment parameter h.

In some embodiments, the tuning parameter e is 3dB greater than the tuning parameter f; the adjusting parameter f is 1.7dB greater than the adjusting parameter g; the tuning parameter g is 1.3dB larger than the tuning parameter h.

As shown in fig. 2 (fig. 2 is a schematic flowchart of a method for measuring a link path loss according to another embodiment of the present disclosure), in some embodiments, the method further includes:

s103: and adjusting the transmission power of the acquired reference signal according to the adjustment parameter.

S104: and measuring link path loss based on the adjusted transmission power of the reference signal.

In some embodiments, data transmission between a terminal and a base station may be based on link path loss.

In the embodiment of the present disclosure, when measuring the link path loss, differences in the transmission power of the reference signal due to different energy per resource unit caused by different information of the sub-bands occupied by the base station are fully considered, and the differences are adaptively adjusted by increasing the adjustment parameters, so as to ensure the reliability and accuracy of the measurement result.

In order to clearly understand the scheme of the embodiment of the present disclosure, the scheme of the embodiment of the present disclosure will be described in detail with reference to the application scenario shown in fig. 3.

As shown in fig. 3, the base station 100 establishes a communication link with the terminal 200 (in fig. 3, a computer is taken as a specific example of the terminal, and the terminal may further include a mobile phone, a smart band, an iPad, a notebook computer, and the like), and the base station 100 transmits data to the terminal 200 based on the communication link and receives data transmitted by the terminal 200 based on the communication link.

In some embodiments, the base station 100 sends the number of sub-bands occupied by the base station (the number of sub-bands is taken as an example here for exemplary illustration, and the principle of combining sub-bands is similar to this and will not be described later) and the transmission power of the reference signal (which may be carried in the protocol higher layer parameters) to the terminal 200.

The reference signal may be a periodic CSI-RS or may not be a periodic CSI-RS, such as an SS/PBCB block (synchronization signal/physical layer broadcast channel block). If the reference signal is not the periodic CSI-RS, the protocol high-level parameters are provided by IE ss-PBCH-Block Power; if the reference signal is a periodic CSI-RS, the protocol high layer parameters are provided by IE ss-PBCH-BlockPower or by the combination of power control OffsetSS and ss-PBCH-BlockPower. See section 7 of 3gpp TS38.213 for a detailed description.

It is noted that the number of sub-bands may be included in the downlink control information. That is, the number of subbands is carried in the downlink control information transmitted from base station 100 to terminal 200.

The terminal 200 is preset with a mapping relationship, which may be carried in a protocol higher layer parameter sent by the base station 100 to the terminal 200 during initialization.

The terminal 200 determines an adjustment parameter corresponding to the number of sub-bands according to the mapping relationship, and adjusts the transmission power of the reference signal according to the adjustment parameter. The adjustment may be to add an adjustment parameter on the basis of the transmission power of the reference signal, so as to calculate the link path loss based on the adjusted transmission power of the reference signal, and the calculation principle is the same as that in the prior art, which is not described herein again.

Of course, in other embodiments, the terminal 200 may also calculate the transmission power of the uplink channel according to the adjustment parameter.

In other embodiments, the mapping relationship may also be stored in the base station 100, and when the base station determines the number of sub-bands it occupies, the adjustment parameter corresponding to the number of sub-bands is determined based on the mapping relationship, and the adjustment parameter and the transmission power of the reference signal are transmitted to the terminal 200.

Similarly, the terminal 200 adjusts the transmission power of the reference signal according to the adjustment parameter. The adjustment may be to add an adjustment parameter on the basis of the transmission power of the reference signal, so as to calculate the link path loss based on the adjusted transmission power of the reference signal, and the calculation principle is the same as that in the prior art, which is not described herein again.

And, the terminal 200 may also calculate the transmission power of the uplink channel according to the adjustment parameter.

As shown in fig. 4 (fig. 4 is a schematic flowchart of a method for measuring a link path loss according to another embodiment of the present disclosure), in some embodiments, the method further includes:

s105: and calculating the transmission power of the uplink channel according to the adjustment parameters.

That is, in the embodiment of the present disclosure, on one hand, the link path loss may be calculated based on the adjustment parameter, and on the other hand, the transmission power of the uplink channel may be calculated based on the adjustment parameter.

Taking data transmission between the terminal and the base station as an example, in the embodiment of the present disclosure, the terminal may determine the transmission power of the uplink channel according to the adjustment parameter, so as to reliably transmit the data to be transmitted to the base station.

The fifth one may be: a bitmap (bitmap) is obtained, in which one bit represents one subband, bit position 1 indicates that the subband is occupied, and bit position 0 indicates that the subband is not occupied.

The information of the uplink resource allocation refers to a bandwidth corresponding to the uplink resource, such as 80MHz.

It should be noted that after the information of the uplink resource allocation is obtained, that is, after the bandwidth corresponding to the uplink resource is determined, the information of the sub-band may be determined based on the bandwidth.

For example, if the bandwidth is 80MHz, it may be determined that the number of sub-bands is 4; alternatively, the combination of sub-bands is determined to be a combination of sub-bands 4.

In some embodiments, the S11 and S12 execution bodies may be the base station, that is, the base station determines the information of its corresponding uplink resource allocation, and the base station determines the information of the sub-bands according to the information of the uplink resource allocation.

In some embodiments, the information of the sub-frequency band is information of a sub-frequency band occupied by a base station corresponding to the preset time period.

In some embodiments, the preset time period may be determined according to the time occupied by the channel after the channel is obtained by the base station; or, the preset time period may be determined according to a time length indicated by the base station through the downlink control information.

In some embodiments, the preset time period may be at least composed of one of a downlink symbol and/or subframe, a flexible symbol and/or subframe, and an uplink symbol and/or subframe.

In one embodiment, the link corresponds to a frequency sub-band occupied by the base station, the terminal and the communication between the base station and the terminal.

S107: and determining information of a sub-band corresponding to the uplink data.

S108: and selecting the adjusting parameters corresponding to the determined information of the sub-frequency bands from the adjusting parameters corresponding to each group of links.

Based on the above example, the information of the sub-bands corresponding to the four groups of links is respectively matched with the information of the determined sub-bands, and if the information of the sub-bands corresponding to a certain group of links in the four groups of links is the same as the information of the determined sub-bands, the adjustment parameter corresponding to the group of links with the same information of the determined sub-bands is selected.
