Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In the civil 5G New air interface (5G New radio,5G NR) standard, a partial Bandwidth (BWP, bandwidth Part) is defined in consideration of different services of a terminal and the capability of the terminal. When the terminal is in the transmission requirements of different services, different partial bandwidths are adopted, so that the power consumption of the terminal and the cost of the terminal are reduced. However, in the private network field, the number of users is relatively small, and there is interference of narrow band and wide band, which may be caused by different systems and may also be malicious interference of enemy, and in addition, the cost of the terminal is relatively civil and the sensitivity is reduced. However, in the civil 5G NR standard, the terminal only has the capability of activating interference measurement in a partial bandwidth, and does not have the capability of measuring each partial bandwidth in the whole carrier bandwidth. For this reason, a strategy for measuring interference information corresponding to each partial bandwidth (including an active partial bandwidth and an inactive partial bandwidth) in a carrier bandwidth needs to be provided to acquire the interference information corresponding to each partial bandwidth in a current carrier.
The interference measurement method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. Wherein terminal 101 and base station 103 communicate. The base station 103 issues the resource configuration parameter of the interference measurement in the carrier bandwidth of the cell in which the terminal 101 is located to the terminal 101, and the terminal 101 receives the resource configuration parameter issued by the base station 103 and executes the interference measurement in the full carrier bandwidth according to the received resource configuration parameter.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments.

The present embodiment relates to a specific implementation process in which a base station determines a carrier bandwidth of a cell in which a terminal is located and a resource configuration parameter of interference measurement in the carrier bandwidth, so that the terminal performs interference measurement in the entire carrier bandwidth according to the determined resource configuration parameter. As shown in fig. 2, the method may include:
s201, determining the carrier bandwidth of a cell where a terminal is located, wherein the carrier bandwidth comprises an activated partial bandwidth and an inactivated partial bandwidth;
in NR, one cell supports multiple fractional bandwidths, and at most 4 fractional bandwidths are supported, where each fractional bandwidth corresponds to one parameter set, that is, the subcarrier sizes of each fractional bandwidth may not be the same. Specifically, the base station first determines a carrier bandwidth of a cell in which the terminal is located, where the carrier bandwidth includes an activated partial bandwidth and an inactivated partial bandwidth. Wherein the carrier bandwidth is a carrier bandwidth in the 5G standard. It should be noted that, in order to enable the terminal to measure the interference within the intra-cell carrier bandwidth, the base station needs to reserve a cell-based full-carrier zero-power reference signal (ZP-CSI RS) to measure the interference power of the electromagnetic environment in consideration of different subcarrier spacings, in the NR R15 version, for FR1 in the 5G standard, the supported subcarrier spacing is 15kHz/30kHz/60kHz, and for FR2, the supported subcarrier spacing is 60kHz/120kHz.
S202, determining resource configuration parameters of interference measurement in the carrier bandwidth.
Specifically, after determining the carrier bandwidth of the cell in which the terminal is located, the base station determines the resource configuration parameter of interference measurement in the carrier bandwidth. The resource configuration parameters comprise sparsity parameters of a plurality of subcarrier interval type resources, offsets in a frequency domain, a measurement period and offsets in a time domain. It can be understood that an offset (IM _ frequency _ offset) in the frequency domain may be associated with the cell ID, and if the interference measurement resources of the neighboring cells are staggered, the environmental noise measured by the terminal includes the transmission power of the neighboring cells; if the interference measurement resources of the adjacent cells overlap, the environmental noise measured by the terminal does not contain the transmission power of the adjacent cells.
Exemplarily, when the carrier bandwidth of the cell where the determined terminal is located is FR1, the unit with the smallest interference measurement in the time domain may be selected as the largest symbol unit length in 15kHz/30kHz/60kHz, that is, 1/14ms corresponding to 15 kHz; the unit in which the interference measurement is smallest in the frequency domain may be selected as the width of the largest one subcarrier of 15kHz/30kHz/60kHz, i.e. 60kHz. As shown in fig. 3-5, the time-frequency resource diagram is a time-frequency resource diagram of a minimum resource unit of interference measurement in a carrier bandwidth when a carrier bandwidth of a cell in which a terminal is located is FR1 and a subcarrier interval is 15kHz/30kHz/60kHz, where IM _ frequency _ offset is 60kHz, which is the unit of the largest subcarrier interval in FR1, and then IM _ frequency _ offset may be 0, 1, and 2 in FR 1. In FR1, the position of the minimum interference measurement resource unit in the entire bandwidth may be in units of Resource Blocks (RBs) corresponding to the maximum subcarrier spacing (i.e., 720 kHz), and the sparsity parameter of the multiple subcarrier spacing type resources may be 2, 1/2, 1/3, etc., which respectively indicates that there are 2 and 1 interference measurement resources in 1 RB, 1 interference measurement resource in 2 RBs, and 1 interference measurement resource in 3 RBs. In the time domain, the interference measurement resource may be configured in a period of a subframe or a radio frame. Under different subcarrier conditions, the time domain positions of the interference measurement resources need to be aligned, as shown in fig. 6-7, under the condition of 15kHz, if the last symbol in the time slot 0 is configured as the interference measurement resource in one radio frame, under the condition of 30kHz, the time domain positions of the interference measurement resource become the last two symbols in the time slot 1; in the 60kHz case, the time domain position of the interference measurement resource becomes the last four symbols in slot 3.
It can be understood that, when the carrier bandwidth of the cell where the determined terminal is located is FR2, the unit with the smallest interference measurement in the time domain may be selected as the largest symbol unit length in 60kHz/1200kHz, that is, 1/56ms corresponding to 60 kHz; the unit in which the interference measurement is minimum in the frequency domain may be selected to be the width of a maximum of one subcarrier in 60kHz/120kHz, i.e., 120kHz. As shown in fig. 8-9, the time-frequency resource diagram is a time-frequency resource diagram of a minimum resource unit of interference measurement in a carrier bandwidth when a carrier bandwidth of a cell in which a terminal is located is FR2 and a subcarrier interval is 60kHz/120kHz, respectively, where an offset (IM _ frequency _ offset) in a frequency domain is 120kHz, which is a unit of a maximum subcarrier interval in FR2, and then, in FR2, IM _ frequency _ offset may be 0, 1, 2, 3, 4, and 5. In FR2, the position of the minimum interference measurement resource unit in the entire bandwidth may be in units of RBs corresponding to the maximum subcarrier spacing (i.e. 1440 kHz), and the sparsity parameter of the plurality of subcarrier spacing type resources may be 2, 1/2, 1/3, etc., which respectively indicates that there are 2 and 1 interference measurement resources in 1 RB, 1 interference measurement resource in 2 RBs, and 1 interference measurement resource in 3 RBs. Similar to FR1, in the time domain, the interference measurement resource may be configured periodically in a subframe or a radio frame. In different sub-carrier conditions, the time domain positions of the interference measurement resources need to be aligned, as shown in fig. 10-11, in the case of 60kHz, if the last symbol in the slot 0 is configured as the interference measurement resource in one radio frame, in the case of 120kHz, the time domain position of the interference measurement resource becomes the last two symbols in the slot 1.
S203, the resource configuration parameters are sent to the terminal, so that the terminal performs interference measurement in the whole carrier bandwidth according to the resource configuration parameters, including interference measurement on activated partial bandwidth and interference measurement on non-activated partial bandwidth.
Specifically, the base station issues the resource configuration parameters of the determined interference measurement in the carrier bandwidth to the terminal, so that the terminal performs the interference measurement in the whole carrier bandwidth according to the issued resource configuration parameters, including the interference measurement on the activated partial bandwidth and the interference measurement on the inactivated partial bandwidth in the whole carrier bandwidth.
In this embodiment, the carrier bandwidth of the cell in which the terminal is located, which is determined by the base station, includes the activated partial bandwidth and the inactivated partial bandwidth, so that the resource configuration parameter of the interference measurement in the determined carrier bandwidth is issued to the terminal, so that the terminal can perform the interference measurement including the interference measurement on the activated partial bandwidth and the interference measurement on the inactivated partial bandwidth according to the issued resource configuration parameter, and by this way, the interference information corresponding to each partial bandwidth in the current carrier can be obtained, and the interference in each partial bandwidth in the entire carrier bandwidth can be measured.
On the basis of the foregoing embodiment, as an optional implementation manner, the foregoing method further includes: and informing the terminal to activate or deactivate the interference measurement in the whole carrier bandwidth based on the resource configuration parameters through a medium access control layer control unit.
Specifically, the base station notifies the terminal to activate or deactivate the interference measurement in the whole carrier bandwidth based on the resource configuration parameter through a medium access control layer (MAC layer) control unit. It should be noted that, notifying the terminal to activate the interference measurement in the whole carrier bandwidth based on the resource configuration parameter indicates to trigger the terminal to perform the interference measurement in the whole carrier bandwidth based on the resource configuration parameter; notifying the terminal to deactivate performing the interference measurement in the entire carrier bandwidth based on the resource configuration parameter means stopping the terminal from performing the interference measurement in the entire carrier bandwidth based on the resource configuration parameter.
In this embodiment, the base station notifies the terminal to activate or deactivate the interference measurement performed in the entire carrier bandwidth based on the resource configuration parameter through the mac layer control unit, so that the terminal can perform the intra-carrier interference power measurement semi-statically, which is convenient for the terminal to perform the interference power measurement operation.
On the basis of the foregoing embodiment, as an optional implementation manner, the foregoing method further includes: and skipping the resource position corresponding to the resource configuration parameter when the resource configuration parameter is issued to the terminal.
Specifically, when the base station issues the resource configuration parameter to the terminal, the base station skips over a resource location corresponding to the resource configuration parameter, that is, there is no transmission power at the resource location in the cell where the terminal is located. In this embodiment, when the base station issues the resource configuration parameter to the terminal, the base station skips over the resource location corresponding to the resource configuration parameter, so that resources are saved, and unnecessary resource waste is avoided.
Fig. 12 is a schematic flowchart of an interference measurement method according to another embodiment; fig. 13 is a schematic diagram of interference measurement and partial bandwidth mapping in a carrier bandwidth according to an embodiment. The embodiment relates to a specific implementation process that a terminal receives a resource configuration parameter of interference measurement in a carrier bandwidth sent by a base station and executes the interference measurement in the full carrier bandwidth according to the resource configuration parameter. As shown in fig. 12, the method may include:
s1201, receiving a resource configuration parameter of interference measurement in a carrier bandwidth sent by a base station; the carrier bandwidth is the carrier bandwidth of the cell where the terminal is located, and comprises an activated partial bandwidth and an inactivated partial bandwidth.
Specifically, the terminal receives a resource configuration parameter of interference measurement in a carrier bandwidth, which is sent by the base station. The resource configuration parameters comprise sparsity parameters of a plurality of subcarrier interval type resources, offset on a frequency domain, a measurement period and offset on a time domain.
And S1202, performing interference measurement in the full carrier bandwidth according to the resource configuration parameters, wherein the interference measurement comprises interference measurement of activated partial bandwidth and interference measurement of inactivated partial bandwidth.
Specifically, the terminal performs interference measurement in the full carrier bandwidth according to the resource configuration parameters of the intra-carrier bandwidth interference measurement sent by the base station, including interference measurement on activated partial bandwidth and interference measurement on non-activated partial bandwidth. Optionally, before the terminal performs interference measurement in the full carrier bandwidth according to the resource configuration parameter, the terminal configures a filter and a low noise amplifier at a radio frequency front end of the terminal to be in a broadband receiving mode, performs demodulation of downlink data and interference measurement in the full carrier bandwidth after performing fourier transform processing on the received resource configuration parameter, and/or receives a notification that the base station activates or deactivates the interference measurement performed in the full carrier bandwidth based on the resource configuration parameter. Illustratively, if the terminal receives a notification sent by the base station to activate the execution of the interference measurement within the entire carrier bandwidth based on the resource configuration parameters, the terminal turns on the broadband receiver at a specific measurement time of the measurement period to execute the interference measurement within the entire carrier bandwidth at a subcarrier interval of the currently activated partial bandwidth, and if the terminal receives the notification sent by the base station to deactivate the execution of the interference measurement within the entire carrier bandwidth based on the resource configuration parameters, the terminal exits the interference measurement within the entire carrier bandwidth. Optionally, when performing interference measurement in the entire carrier bandwidth, the terminal may adopt a forgetting filtering method to filter fluctuation caused by randomness in the time domain, so as to obtain an average value in the time domain. It should be noted that, in the frequency domain, the interference measurement resource in the carrier bandwidth measured by the terminal may have a certain corresponding relationship with a partial bandwidth allocated to the terminal by the base station, as shown in fig. 13, the 1 st and 2 nd interference measurement resources in the frequency domain are in the frequency domain range of the partial bandwidth 1, so the measurement value thereof may be used as the interference power in the frequency domain of the partial bandwidth 1, and the 8 th interference measurement resource in the frequency domain is in the frequency domain range of the partial bandwidth 2, so the measurement value thereof may be used as the interference power in the frequency domain of the partial bandwidth 2.
In this embodiment, the terminal receives a resource configuration parameter of interference measurement in a carrier bandwidth, which is sent by the base station, performs interference measurement on an activated partial bandwidth and interference measurement on an inactivated partial bandwidth according to the resource configuration parameter, obtains interference information of each partial bandwidth, and can avoid interference based on the interference information of each partial bandwidth, thereby improving the performance of air interface transmission.
