CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202211527181.4 filed in China on November 30, 2022, the entire contents of which are incorporated herein by reference.

Technical Field

The present application belongs to the field of communication technology, and specifically relates to a measurement method, device, terminal and network side equipment.

Background technique

With the development of communication technology, full-duplex mode has been introduced in communication systems. In full-duplex mode, independent antennas are usually required for transmission and reception, such as different antenna elements or antenna panels. At the same time, the transmitting antenna and the receiving antenna are isolated to reduce mutual interference.

In the time division duplex (TDD) mode, when the network side device is measuring the uplink channel or the terminal is measuring the downlink channel, it is usually assumed that the uplink and downlink channels are reciprocal, so as to reduce the overhead of channel measurement. In full-duplex mode, after the network side device uses independent transmitting antennas and receiving antennas for a certain degree of isolation, the spatial characteristics may be different, so the uplink and downlink channel reciprocity cannot be guaranteed. In addition, when the network side device operates in full-duplex mode, it may switch to half-duplex mode (i.e., only transmit or only receive) at some times, and may switch back to full-duplex mode. This switching between full-duplex mode and half-duplex mode may require corresponding changes to the antenna configuration of the network side device, resulting in reduced reliability of downlink measurement.

For ease of understanding, some contents involved in the embodiments of the present application are described below:

1. For asymmetric spectrum of TDD.

Different frequency domain resources on certain TDD time slots/symbols can be semi-statically configured or dynamically indicated as having both uplink transmission and downlink reception.

2. For half-duplex terminals.

At the same time, the terminal can only perform uplink transmission or downlink reception, that is, the terminal cannot receive and transmit signals at the same time.

3. Slot format

In order to achieve flexible network deployment, the NR system configures the transmission direction of each symbol in a time slot through the time slot format.

There are three definitions of the transmission direction of time slots in NR: downlink (DL), uplink (UL) and flexible. When the network side device configures a time slot or symbol as DL or UL, the transmission direction at that moment is clear; when the network side device configures a time slot or symbol as flexible, the transmission direction at that moment is undetermined. The network side device can modify the transmission direction of a flexible time slot or symbol through dynamic signaling, such as dynamic SFI (slot format indicator).

A slot can contain downlink, uplink and flexible orthogonal frequency division multiplexing (OFDM) symbols; Flexible symbols can be rewritten as downlink or uplink symbols.

Optionally, a slot format indicator (SFI) may indicate the format of one or more slots. The SFI is sent in the Group Common Physical Downlink Control Channel (GC-PDCCH).

SFI can flexibly change the slot format according to demand to meet business transmission requirements.

The user equipment (UE) decides whether to monitor the PDCCH based on the instructions of the SFI.

Optionally, the slot configuration includes the following:

1. The network-side device can semi-statically configure one or more cell-specific slot formats for the UE through the higher-layer parameters UL-DL-configuration-common and UL-DL-configuration-common-Set2 (optional).

2. The network-side device can also semi-statically configure one or more UE-specific slot formats through the high-level parameter UL-DL-configuration-dedicated.

3. The network side device can rewrite the flexible symbol or slot in the semi-static configuration through the SFI carried in the GC-PDCCH.

4. Quasi co-location (QCL) of Channel State Information Reference Signal (CSI-RS).

1. The case where CSI-RS and control resource set (CORESET) have overlapping orthogonal frequency division multiplexing (OFDM) symbols:

For the case where repetition is not configured "on" for CSI-RS, if the UE is configured with a CSI-RS resource in the same OFDM symbol or symbols as a search space associated to a CORESET, the UE may assume that the CSI-RS and the demodulation reference signal (DMRS) of the physical downlink control channel (PDCCH) of all search space sets associated to the CORESET are of quasi-co-located type D (QCL-Type D), if QCL-Type D is available. This also applies when the CSI-RS and the CORESET are on different intra-band carriers.

2. QCL of Aperiodic CSI-RS (A-CSI-RS)

A CSI-RS resource set associated with a CSI triggering state may include one or Multiple A-CSI-RS resources. The TCI state or QCL of each A-CSI-RS resource is configured by high-level parameters. One or more CSI trigger states can be indicated in the DCI. When an A-CSI-RS resource is associated with one of the CSI trigger states, there are multiple situations. The scheduling offset 2 (offset2) is the number of symbols between the last symbol of the PDCCH carrying the downlink control information (Downlink Control Information, DCI) and the first symbol of the A-CSI-RS resource for which trs-Info is not configured in the CSI-RS resource set configuration parameter (NZP-CSI-RS-ResourceSet).

5. Configured Grant (CG) Resources

To meet the needs of low-latency or periodic services, NR supports two uplink transmission (configured UL grant) modes of uplink semi-static scheduling authorization: type 1 and type 2. The configured UL grant type 1 resource can be semi-statically configured through RRC signaling. After receiving the configuration, the user can transmit it based on the arrival of its own services and configuration, without the need for dynamic scheduling via DCI. The configured UL grant type 2 resource can be semi-statically configured through RRC signaling. After receiving the configuration, the user cannot use it directly. The network-side device further activates the configuration through DCI before the user can use the grant resource according to the activated DCI. The network-side device can also deactivate the configuration through DCI, and the user who receives the deactivated DCI will stop the grant resource.

6. Random Access Channel (RACH) resource configuration.

In the time domain, through the Physical Random Access Channel (PRACH) configuration index (Configuration Index), the network side device instructs the UE what PRACH format to use and where to send the preamble.

For the long preamble (format 0 to 3), the UE mainly needs to know which subframes of which system frames can send the Preamble (the starting symbol of the long preamble is usually 0, and in a few cases 7).

For short preambles (format A1, A2, A3, B1, B2, B3, B4, C0, C2), the UE also needs to know which symbols in which time slots can send the Preamble.

At present, the terminal determines the transmit power of the uplink transmission according to the uplink power control configuration configured by the network. The parameters for uplink power control transmitted by an uplink channel, such as the target transmit power or the downlink reference signal for path loss estimation, are also configured by the network-side device. In full-duplex mode, the network-side device uses independent transmitting antennas and receiving antennas for certain isolation, and the channel reciprocity of the uplink and downlink cannot be guaranteed. At the same time, the switching between full-duplex mode and half-duplex mode may require corresponding changes to the antenna configuration of the network-side device, resulting in a reduction in the reliability of the downlink measurement. For this reason, the measurement method of the present application is proposed.

The following describes the measurement method provided in the embodiment of the present application in detail through some embodiments and their application scenarios in combination with the accompanying drawings.

Referring to FIG. 2 , an embodiment of the present application provides a measurement method. As shown in FIG. 2 , the measurement method includes:

Step 202: the terminal receives a target downlink reference signal resource according to the second information, and performs channel measurement or interference measurement;

In the embodiment of the present application, the downlink reference signal resource can be understood as a CSI-RS resource or a CSI-RS resource, or can be understood as an SSB resource. That is, the downlink reference signal can be a CSI-RS or an SSB. In the following embodiments, the downlink reference signal can be described as a CSI-RS.

Optionally, the time domain type may include:

Uplink (UL), time domain unit for uplink;

Downlink (DL), a time domain unit for downlink;

Full-duplex/flexible duplex can be used for DL, UL and/or Flexible time domain units. Specific types may include subband full-duplex (SBFD).

Optionally, the time domain format or time domain type may be indicated by a time division duplex uplink and downlink configuration (TDD-UL-DL-Configuration) or a frequency division duplex uplink and downlink configuration (FDD-UL-DL-Configuration), or a flexible duplex uplink and downlink configuration (XDD-UL-DL-Configuration), etc. It may be configured by a network high layer, such as by terminal-specific signaling, or by broadcast signaling.

The above-mentioned full-duplex sub-band configuration information or full-duplex sub-band indication information can be used to indicate the full-duplex frequency domain UL sub-band format, the full-duplex frequency domain DL sub-band format, the guard band (Guard band), the downlink (DL) bandwidth part (Bandwidth Part, BWP), and the uplink bandwidth part (UL BWP).

Optionally, the corresponding spatial attributes can be determined based on the above-mentioned second information, so that the downlink reference signal resources can be received based on the spatial attributes corresponding to the second information. In this way, when the network side device switches the antenna configuration, the downlink reference signal resources can be transmitted and channel measurement or interference measurement can be performed using the spatial attributes suitable for the current antenna configuration.

Optionally, the above-mentioned downlink reference signal configuration can be understood as a downlink reference signal resource configuration or a downlink reference signal resource set configuration. Among them, the downlink reference signal configuration can correspond to one or more spatial attributes. When the downlink reference signal configuration corresponds to multiple spatial attributes, a downlink reference signal resource or a downlink reference signal resource set indicated by the downlink reference signal configuration can correspond to one or more spatial attributes. It should be understood that the above-mentioned downlink reference signal resource configuration may include the number of the resource or the resource set, which may also be referred to as an index.
