Description

Measurement method, device, terminal and network side equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to a measuring method, a measuring device, a terminal and network side equipment.

Background

With the development of communication technology, a full duplex mode is introduced in a communication system, and in the full duplex mode, separate antennas are generally required to be used for transmitting and receiving, for example, different antenna arrays or antenna panels are used for transmitting and receiving. At the same time, the transmitting antenna and the receiving antenna are isolated as necessary to reduce interference with each other.

In the time division multiplexing (Time Division Duplex, TDD) mode, when the network side device performs measurement on an uplink channel or the terminal performs measurement on a downlink channel, it is generally assumed that the uplink and downlink channels have reciprocity, so as to reduce the overhead of channel measurement. In the full duplex mode, after the network side device adopts the independent transmitting antenna and the receiving antenna to perform certain isolation, the spatial characteristics may be different, so that the reciprocity of the uplink and downlink channels cannot be ensured. In addition, when the network side device operates in the full duplex mode, it may be possible to switch to the half duplex mode (i.e., transmit only or receive only) at some point, and may switch back to the full duplex mode. Such switching between full duplex and half duplex modes may require a corresponding change in the antenna configuration of the network side device, resulting in reduced reliability of the downlink measurements.

The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may be a Mobile phone, a tablet Computer (Tablet Personal Computer), a Laptop (Laptop Computer) or a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a palm Computer, a netbook, an ultra-Mobile Personal Computer (ultra-Mobile Personal Computer, UMPC), a Mobile internet device (Mobile INTERNET DEVICE, MID), a Mobile terminal, Augmented reality (augmented reality, AR)/Virtual Reality (VR) equipment, robots, wearable equipment (Wearable Device), vehicle-mounted equipment (VUE), pedestrian terminals (PUE), smart home (home equipment with wireless communication function, such as refrigerators, televisions, washing machines or furniture), game machines, personal computers (personal computer, PCs), teller machines or self-service machines, and other terminal side equipment, and the wearable equipment includes: intelligent watch, intelligent bracelet, Intelligent headphones, intelligent glasses, intelligent jewelry (intelligent bracelets, intelligent rings, intelligent necklaces, intelligent ankles, intelligent footchains, etc.), intelligent bracelets, intelligent clothing, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

It should be noted that, in the embodiment of the present application, only the core network device in the NR system is described as an example, and the specific type of the core network device is not limited.

For ease of understanding, some of the following descriptions are directed to embodiments of the present application:

1. For the asymmetric spectrum of TDD.

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

2. For half duplex terminals.

The terminal can only perform uplink transmission or downlink reception at the same time, i.e. the terminal cannot both receive and transmit signals at the same time.

3. Slot format (slot format).

In order to realize flexible network deployment, the transmission direction of each symbol in a time slot is configured in a time slot format manner in an NR system.

There are three definitions of the transmission direction of the slots in NR, downlink (DL), uplink (UL) and flexible. When the network side equipment configures a time slot or a symbol which is DL or UL, the transmission direction of the moment is clear; when the network side device configures a time slot or symbol to be flexible, the transmission direction of the moment is pending. The network side device may modify the transmission direction of the slots or symbols of the flexible by dynamic signaling, such as DYNAMIC SFI (slot format indicator).

One slot may contain downlink (uplink) and flexible (flexible) orthogonal frequency division multiplexing (Orthogonal frequency division multiplex, OFDM) symbols; the Flexible symbols may be rewritten as downlink or uplink symbols.

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

The SFI can flexibly change the slot format according to the requirement so as to meet the service transmission requirement.

The UE decides whether to monitor the PDCCH according to the indication of the SFI.

Optionally, the following is included for slot configuration:

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

2. The network side device may also configure one or more UE-specific slot formats with the higher layer parameters UL-DL-configured-decoded semi-statically for the UE.

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

4. Quasi co-location (QCL) of the channel state Information reference signal (CHANNEL STATE Information REFERENCE SIGNAL, CSI-RS).

1. Case of orthogonal frequency division multiplexing (Orthogonal frequency division multiplex, OFDM) symbols where CSI-RS overlaps with the control resource set (Control resource set, CORESET):

For the case where the CSI-RS is not configured repetition (repetition) as "on", if the UE is configured with one CSI-RS resource in the same one or more OFDM symbols as one search space associated to one CORESET, the UE may assume that the CSI-RS is quasi co-located type D (QCL-TypeD) with Demodulation reference signals (Demodulation REFERENCE SIGNAL, DMRS) of physical downlink control channels (Physical downlink control channel, PDCCH) associated to all sets of search spaces of the CORESET if QCL-TypeD is available. CSI-RS and CORESET are also applicable on different intra-band (intra-band) carriers.

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

One CSI-RS resource set associated with one CSI-trigger state (CSI TRIGGERING STATE) may comprise one or more a-CSI-RS resources. The TCI state or QCL of each a-CSI-RS resource is configured by higher layer parameters. One or more CSI trigger states may be indicated in the DCI, and there are a number of cases when an a-CSI-RS resource is associated in one of the CSI trigger states. Wherein the scheduling offset2 (offset 2) 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 in which the trs-Info is not configured in the CSI-RS resource set configuration parameter (NZP-CSI-RS-resource set).

5. Configuring Grant (CG) resources

For the needs of low-delay service or periodic service, the NR supports two uplink transmission (configured UL grant) modes of uplink semi-static scheduling grant: type1 (type 1) and type2.configured UL GRANT TYPE1 resources can be semi-statically configured through RRC signaling, and after the user receives the configuration, the user can transmit according to the service arrival condition and the configuration condition, and DCI is not required to be dynamically scheduled. configured UL GRANT TYPE2 resources can be semi-statically configured through RRC signaling, after the user receives the configuration, the user cannot directly use the configuration, and after the network side device further activates the configuration through DCI, the user can use the grant resources according to the activated DCI. The network side device may also deactivate the configuration through DCI, and the user receiving the deactivated DCI may stop the grant resource.

6. Random access channel (Random ACCESS CHANNEL, RACH) resource allocation.

In the time domain, the index (Configuration Index) is configured through a Physical Random access channel (Physical Random ACCESS CHANNEL, PRACH), and the network side device instructs the UE what PRACH format to use and which locations can transmit a Preamble (Preamble).

For long preambles (formats 0-3), the UE mainly needs to know which subframes (subframes) of which system frames (SYSTEM FRAME) can send a Preamble (the start symbol of the long Preamble is typically 0, and a few cases are 7).

For short preambles (formatA 1, A2, A3, B1, B2, B3, B4, C0, C2), the UE also needs to know which symbols (symbols) of which slots (slots) can transmit the Preamble.

Currently, a terminal determines the transmission power of uplink transmission according to the uplink power control configuration of the network configuration. An uplink channel transmits parameters for uplink power control, such as target transmit power or path loss estimated downlink reference signals, which are also configured by the network side device. In the full duplex mode, after the network side equipment adopts independent transmitting antennas and receiving antennas to perform certain isolation, the reciprocity of uplink and downlink channels cannot be ensured. Meanwhile, the switching between the full duplex mode and the half duplex mode may require corresponding changes to the antenna configuration of the network side device, thereby reducing the reliability of downlink measurement.

The measurement method provided by the embodiment of the application is described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a measurement method, as shown in fig. 2, including:

Step 201, a terminal receives first information from a network side device, where the first information includes at least one downlink reference signal configuration, where the downlink reference signal configuration is used to indicate at least one downlink reference signal resource or at least one downlink reference signal resource set, and each downlink reference signal resource or downlink reference signal resource set corresponds to at least one spatial attribute;

Step 202, the terminal receives the 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 may be understood as a CSI-RS resource or a CSI-RS resource, and may also be understood as an SSB resource. That is, the downlink reference signal may be CSI-RS or SSB, and in the following embodiments, the downlink reference signal may be described as an example of CSI-RS.

Alternatively, the time domain types may include:

uplink (UL) for uplink time domain units;

downlink (DL) for downlink time domain units;

full duplex/Flexible duplex, time domain units available for DL, UL and/or Flexible, and specific types may include sub-band full duplex (subband full duplex, SBFD).

Alternatively, the time domain format or time domain type may be indicated by a time division duplex uplink-downlink Configuration (TDD-UL-DL-Configuration) or a frequency division duplex uplink-downlink Configuration (FDD-UL-DL-Configuration), or a flexible duplex uplink-downlink Configuration (XDD-UL-DL-Configuration), or the like. May be configured by higher layers of the network, for example by terminal-specific signaling, or by broadcast signaling.

The Quan Shuanggong subband configuration information or full-duplex subband indication information described above may be used to indicate a full-duplex frequency domain UL subband format, a full-duplex frequency domain DL subband format, guard band (Guard band), downlink bandwidth portion (DL BWP), uplink bandwidth portion (UL BWP).

Optionally, based on the second information, a corresponding spatial attribute may be determined, so that a downlink reference signal resource is received based on the spatial attribute corresponding to the second information, so that when the network side device switches the antenna configuration, the spatial attribute suitable for the current antenna configuration may be used to transmit the downlink reference signal resource and perform channel measurement or interference measurement.

Alternatively, the above downlink reference signal configuration may be understood as a downlink reference signal resource configuration or a downlink reference signal resource set configuration. The downlink reference signal configuration may correspond to one or more spatial attributes. When the downlink reference signal configuration corresponds to a plurality of spatial attributes, one downlink reference signal resource or one downlink reference signal resource set indicated by the downlink reference signal configuration may correspond to one or a plurality of spatial attributes. It should be appreciated that the above downlink reference signal resource allocation may include a number of resources or resource sets, which may also be referred to as an index.

It should be noted that, transmission in the example of the present application may be understood as transmission and/or reception.

Optionally, in some embodiments, the receiving, by the terminal, the target downlink reference signal resource according to the second information includes:

and the terminal receives a target downlink reference signal resource corresponding to a target space attribute according to the corresponding relation between the downlink reference signal resource or the downlink reference signal resource set and the space attribute, and the target space attribute is determined based on the second information.

In the embodiment of the application, when receiving the downlink reference signal resource, the target space attribute can be determined firstly based on the current second information, and then the downlink reference signal resource associated with the target space attribute is determined based on the corresponding relation between the downlink reference signal resource or the downlink reference signal resource set and the space attribute, so that the determined downlink reference signal resource is sent. Or, when the downlink reference signal resource to be received currently is associated with a plurality of different spatial attributes, the downlink reference signal resource to be received currently can be received by using the target spatial attribute.

Optionally, the correspondence between the downlink reference signal resource or the downlink reference signal resource set and the spatial attribute may be agreed by a protocol or configured by a network side device.

Optionally, in some embodiments, the target downlink reference signal resource satisfies any one of:

Case 1: in the case that different values of the different second information correspond to different bandwidth portions BWP, the target downlink reference signal resource is the downlink reference signal resource associated with one BWP or a downlink reference signal resource in the downlink reference signal resource set;

case 2: under the condition that different values of the second information correspond to different downlink reference signal resource sets, the target downlink reference signal resource is a downlink reference signal resource in one downlink reference signal resource set;

Case 3: under the condition that different values of the second information correspond to N different downlink reference signal resources in one downlink reference signal resource set, the target downlink reference signal resource is at least one downlink reference signal resource in the N downlink reference signal resources, and N is a positive integer;

Case 4: and under the condition that different values of the second information correspond to different spatial attributes of the downlink reference signal resource, the spatial attribute used in the transmission of the target downlink reference signal resource is one of the different spatial attributes.

For the above case 1, based on the correspondence between the CSI-RS resource set and the time domain format, the time domain type, the full duplex subband configuration information, or the full duplex subband indication information, the terminal may receive a CSI-RS resource corresponding to the BWP according to the spatial attribute corresponding to the current second information.

In the embodiment of the application, all downlink reference signal resources can be transmitted by using the spatial attribute corresponding to the second information. For example, each downlink reference signal resource corresponds to at least two spatial attributes, and the terminal may receive the downlink reference signal resource using the spatial attribute corresponding to the second information and perform channel measurement or interference measurement.

For example, in some embodiments, the terminal receiving the target downlink reference signal resource according to the second information includes at least one of:

The terminal receives downlink reference signal resources corresponding to first space attributes in the target downlink reference signal resources at a first moment, and the first space attributes are determined according to the second information corresponding to the first moment;

And the terminal receives the target downlink reference signal resource at a second moment, wherein the second moment is determined based on protocol convention or the second information indicated by the network side equipment.
