Description

Method for measuring cross link interference between user terminals, user terminal and transmission receiving point

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for measuring cross link interference between user terminals, a user terminal, and a transmission receiving point.

Background

There are two duplexing modes in the conventional mobile communication system, i.e., FDD (frequency division duplex) and TDD (time division duplex). FDD systems receive and transmit signals using different frequency bands at the same time, and TDD systems receive and transmit signals using different times at the same frequency band. Compared with TDD, FDD has the advantages of wide uplink coverage, simple interference processing, and the like, and does not require strict synchronization of the network. FDD must use paired transceiving frequency bands, which can fully utilize uplink and downlink frequency spectrum when supporting uplink and downlink symmetric services, and the frequency spectrum utilization ratio of FDD system will be reduced when supporting uplink and downlink asymmetric services.

The 5G (5Generation, fifth Generation) network is centered on user terminal experience, and realizes personalized and diversified service applications. The difference of uplink and downlink flow requirements of different services is large, and the traditional TDD and FDD systems are difficult to better match the diversified service requirements of the 5G network. In order to meet flexible change of uplink and downlink services, a flexible duplex technology or a dynamic TDD technology is provided.

The dynamic TDD technology breaks through the fixed configuration mode of uplink and downlink resources in the traditional cellular network system, and adaptively adjusts the uplink and downlink resources according to the service requirements, thereby improving the frequency spectrum utilization rate. Although the dynamic TDD technology may dynamically configure uplink and downlink Transmission directions according to the cell service state, when adjacent cells transmit information in different directions (uplink or downlink) on the same time-frequency resource, as shown in fig. 1, a cell 1 is in Downlink (DL) and a cell 2 is in Uplink (UL), which may cause two types of Cross-Link Interference (CLI), that is, Interference between TRP (Transmission Reception Point) -TRP and UE (User Equipment) -UE. Because the transmission power of the TRP is usually much greater than that of the UE, and the antenna position is generally higher, the propagation attenuation loss and attenuation between antennas are less, and the interference of the cross link between the TRP and the TRP may greatly reduce the interference-to-interference ratio (SINR) of the uplink signal, in the conventional LTE system, in order to improve the system throughput, it is mainly concerned how to avoid the interference of the downlink transmission on the TRP-TRP of the uplink transmission. Some typical interference cancellation schemes, such as link adaptation, scheduling coordination, and power control, are based on TRP-TRP interference measurements.

Therefore, it is desirable to provide a UE-UE cross link interference measurement technique.

wherein n is zero or a positive integer.

Optionally, in this embodiment, the configuration information of whether to perform the CLI measurement is sent to all or some of the user terminals in the serving cell through RRC (radio resource control) signaling or in another manner.

Referring to fig. 3, a flowchart of a method for measuring cross link interference between user terminals according to another embodiment is shown, where an execution subject of the method is a user terminal located in a serving cell of a first transmission and reception point, and optionally, the user terminal may be an edge user terminal of the serving cell, and the specific steps are as follows:

step 301, receiving configuration information of a measurement RS sent by a serving cell from a second transmission and reception point sent by a first transmission and reception point, where the second transmission and reception point is an adjacent transmission and reception point of the first transmission and reception point;

optionally, the configuration information comprises one or more of: and measuring the time-frequency resource position of the RS, measuring the sending period of the RS, judging whether the RS is multi-beam measurement or not, and indicating all or part of the RS sequence sent by the user terminal. Optionally, symbols occupied by all or part of the measurement RS sequences transmitted by the user terminals in one slot are continuous or discrete.

In this embodiment, the ue and the time-frequency resource location have a one-to-one correspondence, and the neighboring ues need to know the RS measurement sequence but do not need a specific ue ID (identity).

Step 302, according to the received configuration information, performing CLI measurement on each time-frequency resource position corresponding to the user terminal to obtain a CLI measurement value.

Step 303, reporting the CLI measurement value to the first transceiver.

Optionally, in step 303, a notification message sent by the first transmission receiving point is received, where the notification message carries a specified reporting mode of the CLI measurement value; and sending the CLI measured value to a first transmission receiving point from a CLI list according to the notification message in a specified reporting mode, wherein the CLI list records the CLI measured value obtained by the CLI measurement of the user terminal at each time-frequency resource position.

Furthermore, the CLI measurement can be only carried out on the edge user terminal through the configuration of the first transmission receiving point, so that the measurement overhead is effectively reduced; the user terminal corresponds to a specific time-frequency resource position, and the adjacent user terminal only needs to measure the interference information of the corresponding time-frequency resource position to obtain the cross link interference information of the user terminal corresponding to the time-frequency resource position; the influence of a plurality of beams of the user terminal is considered, so that the problems of interference mutation and the like caused by beam transformation can be effectively solved; in addition, the CLI list is optimized, various CLI measurement value reporting modes are provided, and the CLI measurement value reporting overhead is reduced.

Referring to fig. 4, a flowchart of a method for measuring cross link interference between user terminals according to another embodiment is shown, where an execution subject of the method is a second transmission receiving point, and the method includes the following specific steps:

step 401, sending configuration information of a measurement RS to a first transmission and reception point, where the first transmission and reception point sends the configuration information of the measurement RS to all or part of user terminals in a serving cell of the first transmission and reception point, where the second transmission and reception point is an adjacent transmission and reception point of the first transmission and reception point.

Optionally, the configuration information comprises one or more of: and measuring the time-frequency resource position of the RS, measuring the sending period of the RS, judging whether the RS is multi-beam measurement or not, and indicating a measuring RS sequence sent by the user terminal. Wherein, the symbols occupied by the measurement RS sequences sent by all or part of the user terminals in one time slot are continuous or discrete.

In this embodiment, the second transmission and reception point may send the configuration information of the measurement RS to the first transmission and reception point, where the first transmission and reception point configures all or part of the user terminals in the serving cell of the first transmission and reception point to perform CLI measurement, and each UE in all or part of the user terminals performs CLI measurement on each time-frequency resource location corresponding to each user terminal according to the configuration information, thereby implementing inter-user-terminal cross link interference measurement.

Referring to fig. 5, a flowchart of a method for measuring cross link interference between user terminals according to another embodiment is shown, which includes the following specific steps:

step 501, transmitting configuration information of a measurement RS sent by a receiving point configuration cell and cross link interference measurement between user terminals;

the cell edge user terminal can suffer from more serious cross link interference problem than the central user terminal, so the transmission receiving point is considered to only configure the measurement RS and CLI measurement sent by the cell edge user terminal;

specifically, the transceiver may determine whether the ue is an edge ue according to a CQI (Channel Quality Indicator) or an RSRP (Reference Signal Receiving Power) of downlink measurement Channel information of the ue, which is not limited to this.

It is understood that, in this embodiment, the transmission receiving point may also configure, through RRC signaling or other means, all the ues in the cell to perform configuration information transmission and CLI measurement for measuring the RS.

Step 502, the transmission receiving point performs measurement RS configuration and CLI measurement configuration for the user equipment through RRC signaling.

The configuration information of the measurement RS includes one or more of: measuring the position of time-frequency resources of the RS, measuring the sending period of the RS, whether the RS is multi-beam measurement or not, and the like; the configuration information may further indicate a measurement RS sequence transmitted by the user terminal.

The positions of the time-frequency resources of the measurement RS sent by all or part of the user terminals may be continuous (see fig. 6a), or the positions of the time-frequency resources of the measurement RS sent by all or part of the user terminals may be discrete (see fig. 6 b). For example: when 6 ues need to send the measurement RS, symbol positions occupied by the measurement RS are schematically shown in fig. 6a and 6 b.

Optionally, the configuration information of the CLI measurement may include: the CLI measures the location of the time-frequency resource, i.e. the transmission receiving point may configure the CLI of the ue through RRC signaling.

The CLI measurement time-frequency resource configured by the transmission receiving point may be related to the number of UEs in the cell that need to measure CLI. Optionally, the configured CLI measurement time-frequency resource may also be related to the number of beams supported by each UE.

Suppose that: x user terminals measure CLI in a cell, and each user terminal supports m wave beams; one OFDM symbol can support n user terminals to transmit measurement RS in one beam, and configuration is needed

One OFDM symbol is used for transmitting the measurement RS and for CLI measurement,

representing an ceiling function.

One user terminal may occupy multiple CLI measurement time-frequency resources and support multi-beam measurement, and if x user terminals need to send measurement RS and one OFDM symbol supports CLI measurement of one user terminal in m beams, the cell needs x × m CLI measurement time-frequency resource positions in total.

For example: when one ue supports 3-beam measurement, it occupies continuous time-frequency resources as shown in fig. 7a, or it may occupy discontinuous time-frequency resources as shown in fig. 7 b.

It should be noted that, adjacent cells may be configured as different CLI measurement time-frequency resources.

Step 503, the user terminal in the adjacent cell measures the CLI measurement reference signal of each time-frequency resource location to obtain the interference information of each time-frequency resource location.

Optionally, the cells alternately transmit the CLI measurement reference signal and perform CLI measurement.

In this embodiment, the ue and the time-frequency resource location have a one-to-one correspondence, and the adjacent ues need to know the CLI measurement RS sequence but do not need a specific ue ID (identity).

Optionally, the measurement RS sequence is related to at least a cell ID;

alternatively, NR (new radio) SRS (Sounding Reference Signal) pattern is used as the measurement RS.

As shown in fig. 8a, 8b, and 8c, the SRS is configured in the form of TDM (time division multiplexing mode), FDM (frequency division multiplexing mode), or TDM + FDM mode.

The corresponding relation between each CLI measurement time-frequency resource position and each user terminal is known by the transmission receiving point, so that the user terminal only needs to feed back the CLI information of each CLI measurement time-frequency resource position.

Step 504, the interference information of each time-frequency resource position is processed in the cell and reported to the local transmission receiving point.

The reporting mode can be as follows:

the first method is as follows: reporting interference values in all CLI lists;

the second method comprises the following steps: only reporting n CLI maximum values in the CLI list comprises the following steps: n CLI measurement time-frequency resource positions and quantized CLI measurement values (required to be larger than a certain preset value) corresponding to the positions;

the third method comprises the following steps: reporting only the CLI measured values of n user terminals, wherein the value is the maximum value of a plurality of CLI measured values corresponding to the user terminal, and the method comprises the following steps: n CLI measurement time-frequency resource positions and quantized CLI measurement values (required to be larger than a certain preset value) corresponding to the positions;

the method is as follows: reporting only the CLI measurement values of n UEs, wherein the CLI measurement values are the average value of a plurality of CLI measurement values corresponding to the UE, and the method comprises the following steps: n CLI measurement time-frequency resource positions and quantized CLI measurement values corresponding to the positions;

the fifth mode is as follows: each user terminal only supports single-beam CLI measurement, and only reports CLI measurement values (required to be greater than a certain preset value) of n user terminals;

the method six: the ue may choose to report the CLI measurement level with 1-bit indicator, for example: bit 0 indicates that the CLI interference information is less than a certain preset value, and bit 1 indicates that the CLI interference is greater than a certain preset value.

It should be noted that, in the above-mentioned manner, the UE reports the measurement result according to the CLI list without any indication. The first transceiver can instruct the UE to select one of the second to sixth modes to report the interference list through RRC signaling.

Assuming there are two cells, see fig. 9, there is one edge user terminal (UE) in cell 1¹) Receiving the measurement RS with one beam (beam); in cell 2 there are two edge user terminals (UE)₁，UE₂) Transmission receiving point 2(TRP2) transmits a measurement RS for each user terminal using two beams (beam1, beam2), specifically:

1) transmission receiving point 2 configures two edge user terminals (UE) in a cell₁，UE₂) CLI measurements were performed.

Transmission receiving point 2 configures two edge user terminals (UE) of local cell₁，UE₂) Sending a measurement RS, configuring a local cell edge user terminal (UE) by a transmission receiving point 1(TRP1)¹) CLI measurements are made from the received measurement RS.

2) And the transmission receiving point performs interference measurement RS configuration on the user terminal through RRC signaling.
