Description

Information transmission indication method, network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission indication method, a network device, and a terminal.

Background

In a New Radio resource Assisted Access (NR-LAA), before transmitting information, a transmitting node (a base station or a User Equipment (UE, also referred to as a terminal)) needs to perform Clear Channel Assessment (CCA)/enhanced Clear Channel assessment (eCCA) on a Channel with a preset bandwidth to monitor the Channel, that is, perform Energy Detection (ED), and when Energy is lower than a certain threshold, the Channel is determined to be empty, and then the transmitting node may start transmission. Since the unlicensed frequency band is shared by multiple technologies, this contention-based access method causes uncertainty of the available time of the channel. The fixed-location Reference Signal (RS) configuration in the NR is no longer applicable to the unlicensed band, because when the channel is available, the RS may have missed its transmittable location and cannot transmit it, which may result in failure to properly perform the RS reception and various measurements and evaluations of the wireless channel environment by the RS.

After listening to the channel and determining to be empty, the duration of the UE sending the signal needs to be less than a Maximum Channel Occupancy Time (MCOT).

The CCA/eCCA listening bandwidth on the unlicensed spectrum of LTE-LAA is 20 MHz. On the unlicensed spectrum of NR, the listening bandwidth may be in units of 20MHz, or may be in units of other bandwidth sizes.

But the resources available to the base station are not fixed over the unlicensed spectrum. Under the existing mechanism of periodically transmitting system information, a base station may not acquire corresponding resources for a long time, which results in missing the opportunity of transmitting the system information, so that a user cannot quickly acquire the system information.

Embodiments of the present invention are described below with reference to the accompanying drawings. The information transmission indication method, the network equipment and the terminal provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a system using 5th generation (5G) mobile communication technology (hereinafter referred to as a 5G system), and those skilled in the art will appreciate that the 5G NR system is merely an example and is not a limitation.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a User terminal 11 and a base station 12, where the User terminal 11 may be a User Equipment (UE), for example: the terminal side Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present invention. The base station 12 may be a base station of 5G and later releases (e.g., a gNB, a 5G NR NB), or a base station in other communication systems, or referred to as a node B, and it should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.

The NR grant (license) frequency band introduces the concept of Control Resource SET (CORESET), and there are multiple candidate locations in the CORESET that can be used for transmitting Physical Downlink Control Channel (PDCCH). And the user blindly detects the PDCCH in the CORESET configured by the base station.

In the NR sense frequency band, a synchronization Signal Block (synchronization Signal and PBCH Block, SS/PBCH Block for short, SSB) carries a NR Physical Broadcast Channel (PBCH), and the NR-PBCH carries a System Master Information Block (MIB), which carries Remaining Minimum System Information (RMSI) PDCCH configuration Information (also called pdccconfigugsi 1 Information). The first 4 bits of the RMSI-PDCCH configuration help a user to confirm information such as time domain duration, frequency domain bandwidth and frequency domain position occupied by RMSI CORESET, and the last 4 bits indicate the configuration of search space (search space) of type0PDCCH, so that the user is helped to determine the time for monitoring the PDCCH, namely the position of a PDCCH monitoring window.

The PDCCH used to schedule RMSI may be referred to as RMSI PDCCH. A PDCCH for scheduling Other System Information (OSI) may be referred to as an OSI PDCCH. The PDCCH for scheduling paging (paging) may be referred to as a paging PDCCH. In some cases, paging the CORESET, OSI CORESET may multiplex RMSI CORESET.

In the NR sense band, the RMSI core and SSB are multiplexed in a Frequency Division Multiplexing (FDM) or Time Division Multiplexing (TDM), and RMSIPDCCH Synchronization Signals (SS) occur periodically. In FDM multiplexing, core set occupies X symbols, and a Physical Downlink Shared Channel (PDSCH) occupies 2 symbols.

For transmission of system information such as RMSI, the number of bits may be as high as 1700 bits, and to ensure transmission performance, RMSI may only use a lower order modulation scheme, such as Quadrature Phase Shift Keying (QPSK).

In the NR unlicensed frequency band, a base station or a terminal node listens in units of channels (channels) with 20MHz bandwidth, and based on the result of the listening, time-frequency resources occupied by the base station and the terminal for transmission are also in units of 20MHz channels.

On the NR unlicensed band, each channel of 20MHz bandwidth may be considered as a bandwidth part (BWP).

There may be multiple 20MHz unlicensed spectrum available in the network, and the network may transmit system information on multiple channels, increasing the transmission opportunity of the system information.

Besides the transmission of the system information, the transmission opportunities of other downlink broadcast information can also be increased, and the time delay is reduced. E.g., a paging message, a Random Access Response (RAR), a random access message four (MSG 4).

Specifically, as shown in fig. 2, an embodiment of the present invention provides an information transmission indication method, which is applied to a network device, and includes:

step 201, sending configuration information of target information through a physical broadcast channel PBCH, where the configuration information includes: indication information of at least one resource for receiving the target information;

It should be noted that the preset bandwidth is a unit bandwidth for listening, for example, the spectrum resource of the preset bandwidth may be a channel with a bandwidth of 20MHz, and the channel with the bandwidth of 20MHz may also be regarded as a bandwidth portion (BWP).

It should be noted that, by using the configuration information of the target information sent by the PBCH to indicate the resource for receiving the target information, the opportunity of receiving the target information can be increased, the transmission of the target information can be ensured, and the reliability of network communication can be ensured.

It should be noted that the first SSB refers to an SSB other than the current PBCH, and the SSB that transmits the current PBCH is referred to as a second SSB, which is also referred to as a current SSB. For example, the terminal performs PBCH transmission on the current SSB, and the first SSB refers to other SSBs besides the current SSB.

It should be further noted that the configuration information further includes at least one of the following information:

a1, the position of the first resource transmitting the second SSB in the unlicensed spectrum;

for example, a number indicating that the first resource is in the unlicensed spectrum.

A2, the bandwidth or the number of channels of the unlicensed spectrum which carries out downlink transmission;

in this case, it is necessary to specify the size of the bandwidth of the unlicensed spectrum for downlink transmission or specify the number of channels of the unlicensed spectrum for downlink transmission.

A3, identification information of at least one second resource;

it should be noted that the identification information may be an index of the second resource; or the identification information may be an offset of the second resource relative to the first resource. It should be further noted that the first resource and the second resource are different resources, that is, the at least one second resource is: a resource of the at least one resource other than the first resource.

Optionally, the configuration information is further configured to:

at least one of Other System Information (OSI), a Random Access Response (RAR), a paging message, and a random access message indicating transmission on the at least one resource.

It should be noted that, in this case, at least one resource may be used for not only the transmission of the first SSB and/or the RMSI, but also at least one of OSI, RAR, paging message, and random access message, and the terminal may receive not only the first SSB and/or RMSI, but also at least one of OSI, RAR, paging message, and random access message in the at least one resource.

Further, the at least one resource includes: the first resource and/or the at least one second resource of the second SSB is transmitted.

Optionally, the at least one resource includes: when the target information includes the RMSI, the configuration information further includes:

a search space and/or a set of control resources of a RMSI Physical Downlink Control Channel (PDCCH) transmitted on the at least one resource.

It should be further noted that, at the at least one resource, the following are included: when the target information includes the RMSI, if the number of the at least one second resource is greater than or equal to two, the at least one second resource satisfies at least one of the following conditions:

b1, the first information on each second resource is the same as the search space and/or control resource set of the first resource;

b2, first information on a different second resource, using a different configuration;

b3, first information on a different second resource, using the same configuration;

in this case, preferably, the second resource uses the same configuration as the first resource.

B4, using the first information on all the second resources to use the preset configuration;

it should be further noted that the preset configuration includes a search space configuration, and the search space configuration includes at least one of the following information:

b41, at least one of a subframe, a time slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol and a control resource set configuration for PDCCH monitoring;

b42, identification information of the starting and ending resource blocks of the PDSCH;

b43, identification information of starting and ending resource blocks of PDSCH;

specifically, the identification information mentioned in B42 and B43 may be an index of the resource block.

B44, number of resource blocks for PDSCH transmission.

For example, the preset configuration may be a default location, i.e., all configuration information in the search space configuration is configured default information.

It should be further noted that the first information mentioned above includes: RMSI PDCCH search space and/or RMSIPDCCH control resource sets.

It should be further noted that, when the target information includes the RMSI, after the sending of the configuration information of the target information through the physical broadcast channel PBCH, the method further includes:

and transmitting the PDCCH of the RMSI and/or the PDSCH of the RMSI on the at least one resource.

Specifically, the network device may transmit the PDCCH and/or PDSCH of the RMSI on any one of the at least one resource, or the network device may transmit the PDCCH and/or PDSCH of the RMSI on all the at least one resource, and the terminal only needs to receive the PDCCH and/or PDSCH of the RMSI on the at least one resource indicated by the network device.

It should be further noted that the PBCH may also be used to indicate: a third resource satisfying a quasi co-location (QCL) relationship with the first resource transmitting the second SSB.

It should be noted that the third resource may include the at least one second resource, or the third resource is a resource other than the at least one second resource.

For example, when the current SSB is transmitted on channel 1, the PBCH is also used to indicate that channel 2 and channel 1 satisfy the QCL relationship, i.e., the QCL relationship is satisfied between the physical signal and the physical channel transmitted at the same time.

Specifically, the parameters of the QCL include at least one of the following parameters: doppler shift (Doppler shift), Doppler spread (Doppler spread), average delay time (average delay), delay spread (delay spread), Spatial Rx parameter (Spatial Rx parameter), and average gain (average gain).

The following describes a specific implementation of an embodiment of the present invention in practical use.

In the unlicensed frequency band, a frequency band bandwidth that can be used by the network device is at most 80MHz, that is, at most 4 channels (channels) may be used, as shown in fig. 3, the network device performs SSB transmission on channel 1, where information indicated by PBCH may be divided into the following cases.

Situation one

Indicating the bandwidth of all available unlicensed bands and the location of the channel (or BWP) in which the current SSB is located in all available unlicensed bands. For example, if the SSB is transmitted on channel 1, the index number of the current channel is indicated in the PBCH, for example, the index number of the current channel is 1, the current channel is the 2 nd channel in the available continuous unlicensed frequency band, and the 1 st channel (channel 0) is in the lower frequency bandwidth of 20 MHz.

In addition, the network device may indicate the bandwidth of the unlicensed frequency band in the PBCH, for example, the maximum bandwidth that can be used on the unlicensed frequency band is 80MHz, and then the number of available channels in the PBCH may be indicated as 4.

Situation two

If there are 4 available channels (or BWPs), the channels that can receive the downlink broadcast information may be other than the channel that transmits the SSB. It can be indicated by PBCH which channels can transmit downlink broadcast information. For example: the SSB and RMSI may be sent on channel 1, while the network may send the SSB and/or RMSI on channel 2, and the network may indicate via PBCH or RMSI that the SSB and/or RMSI may be sent on channel 2.

The terminal may perform SSB and/or RMSI reception on channel 1, or channel 2, or both channel 1 and channel 2, as indicated by the PBCH.

Preferably, if the network indicates that there is more than one channel (or BWP) that can transmit the RMSI in addition to the channels transmitted by the SSBs, the search spaces of the RMSI on these channels (or BWPs) are the same, and the CORESET size and the relative position in the frequency domain within the BWP are the same.

Situation three

The network indicates, by PBCH, that channel 0, channel 1 and channel 2 (or BWP0, BWP1 and BWP2) are used for RMSI transmission, then the terminal assumes that the PDCCH in the RMSI search space on the 3 channels (or BWPs) indicated by PBCH and the SSB where the PBCH is located satisfy the QCL relationship.

Alternatively, the SSB is transmitted on channel 0 (or BWP0), and the PBCH indicates that channel 1 (or BWP1) and the current channel (or BWP) satisfy the QCL. I.e., the QCL relationship is satisfied between the physical channel and the physical signal transmitted at the same time on two channels (or BWPs).

Situation four

Assuming that the current network needs to transmit 9 pieces of system information, i.e., OSI (SIB2-SIB9) in addition to RMSI (SIB1), channels for OSI transmission can be configured separately through RMSI configuration. For example, the current network occupies two channels, channel 0 and channel 1, the network may configure SIB2, SIB4, SIB6 and SIB8 to transmit on channel 0, or SIB3, SIB5, SIB7 and SIB9 to transmit on channel 2, respectively, and may configure some OSI message to transmit on multiple channels.

In the embodiment of the invention, the system information/broadcast information is transmitted on a plurality of channels (or BWPs) to increase the transmission opportunities of the information on the unauthorized frequency band, thereby avoiding the problem that the network equipment cannot transmit SSB and/or RMSI because the network equipment cannot acquire the channel transmission opportunities as far as possible, ensuring that the user cannot acquire the SSB and/or RMSI quickly and further ensuring the effectiveness of network communication.

As shown in fig. 4, an embodiment of the present invention further provides an information transmission indication method, which is applied to a terminal, and includes:

step 401, receiving configuration information of target information sent by a network device through a physical broadcast channel PBCH, where the configuration information includes: indication information of at least one resource for receiving the target information;

and receiving a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH) of the RMSI on at least one resource.

Optionally, the second information transmitted on the at least one resource and the second SSB satisfy a quasi co-located QCL relationship;

wherein the second information comprises: RMSI PDCCH and/or RMSI PDSCH

It should be further noted that, when the second information includes: RMSI PDCCH, the second information is located in RMSI PDCCH search space and/or in the set of control resources in which RMSI PDCCH is located.

It should be noted that all the descriptions regarding the terminal in the above embodiments are applicable to the embodiment of the method for indicating transmission of information applied to the terminal, and the same technical effects can be achieved.
