Description

System information transmission method, network equipment and terminal

Technical Field

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

Background

In a mobile communication system, a terminal needs to read broadcast information when accessing the system or in an idle state. These broadcast Information include Remaining Minimum System Information (RMSI), Other System Information (OSI), Paging (Paging) messages, and the like.

Before the RMSI is acquired, the terminal cannot acquire information contained in the RMSI, that is, cannot acquire a corresponding bandwidth configuration and a starting reference point of a Component Carrier (CC), and at this time, the terminal needs to divide a Precoding Resource Block Group (PRG) according to a starting position of a Control Resource Set (CORESET) scheduled by broadcast information. After the terminal acquires the RMSI, the PRG is divided by using the initial reference point of the CC as a starting point.

However, in the case that the Bandwidth Part (BWP) of the terminal includes the initial (initial) BWP, if the terminal needs to schedule the System Information Block one (System Information Block1, SIB1) to update the System Information and other terminals in the same cell also need to schedule SIB1 for the initial access procedure, the network device configures a set of SIBs 1 on the initial BWP to share to different terminals, but since the terminal updating the System Information already acquires the RMSI, the partition of the PRG is based on the start reference point of the CC, and the terminal performing the initial access does not acquire the RMSI, and the partition of the PRG is based on the start position of the CORESET scheduled by the broadcast Information to partition the PRG, so these terminals cannot share the SIB 1.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 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), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention, only the Base Station in the NR system is taken as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission.

An embodiment of the present invention provides a system information configuration method, which is applied to a communication device, where the communication device may be a terminal or a network device, as shown in fig. 2, and the method includes the following steps:

step 21: in case of scheduling the system information block by the active bandwidth part BWP, the system information block is transmitted according to the start position of the pre-coding resource block group PRG in the active BWP. Wherein the starting position of the PRG is related to at least one of a target control resource set CORESET and update indication information of the system information block, and the active BWP overlaps at least part of frequency domain resources of the initial BWP.

The active BWP is one of multiple BWPs supported by the network device and the terminal, and the initial BWP is a default BWP of the system, that is, the default BWP used when the terminal does not access the system. The at least partial frequency-domain resource overlap of the active BWP with the initial BWP means that the active BWP overlaps with the frequency-domain resource of the initial BWP. For example, as shown in fig. 3, the frequency-domain resources of the active BWP completely overlap with the frequency-domain resources of the initial BWP; alternatively, as shown in fig. 4, the start position of the frequency-domain resource of the active BWP is aligned with the start position of the frequency-domain resource of the initial BWP; or, the end position of the frequency-domain resource of the active BWP, not shown in the figure, is aligned with the end position of the frequency-domain resource of the initial BWP; alternatively, as shown in fig. 5, the frequency-domain resources of the active BWP contain the complete frequency-domain resources of the initial BWP. It is worth noting that the target CORESET may refer to a set of control resources where frequency domain resources overlap with frequency domain resources of the initial BWP.

The system information block referred to herein may refer to SIB1, and when the network device schedules SIB1 for the terminal by activating BWP, the network device may transmit SIB1 according to the starting position of PRG in the activated BWP. Accordingly, the terminal receives the SIB1 according to the starting position of the PRG in the active BWP. In the conventional technique, the starting position of the PRG in the active BWP is related to the component carrier CC where the active BWP is located, so that when there is an initial access of another terminal through the initial BWP that overlaps with the frequency domain of the active BWP, the starting position of the PRG in the initial BWP is related to the control resource set CORESET, so that on the same frequency domain resource, terminals in different states consider that the starting positions of the PRGs are different, and the result of dividing the PRGs may also be different. In order to avoid the above problem, the starting position of the PRG may be determined according to at least one of the target CORESET and the update indication information of the system information block, so as to avoid the interference problem that the network device configures the system information block for different terminals.

Embodiments of the present invention include, but are not limited to, the following ways of determining the starting position of the PRG:

mode one, the starting position of the PRG in the active BWP is related to the target CORESET.

In this way, when the current active BWP of the terminal overlaps with at least part of the frequency domain resources of the initial BWP, after the terminal receives the update indication information for updating the system information block, the terminal determines the starting position of the PRG in the active BWP according to the target CORESET, thereby determining the division result of the PRG in the active BWP, and receives the system information block sent by the network device according to the division result of the PRG.

Specifically, the starting position of the PRG is determined according to the minimum resource block index of the target CORESET. Wherein the minimum resource block index of the target CORESET is scheduled or indicated by a Physical Broadcast Channel (PBCH). The minimum resource block index of the target CORESET may be 0, then the starting position of the PRG in the active BWP may be determined from CORESET 0. As shown in fig. 3 to 5, the starting position of the PRG in the activated BWP may be the starting position of the CORESET0, wherein the target CORESET is all the control resource sets in the initial BWP, and the frequency domain starting point of the CORESET0 may be the same as the frequency domain starting point of the initial BWP.

That is to say, in the case that the frequency domain resources of the active BWP of the terminal overlap with the frequency domain resources of the initial BWP, if the network device indicates that the terminal needs to update the system information, after the terminal acquires the update indication information of the updated system information, it is assumed that the starting position of the PRG partition in the active BWP is the starting point of the CORESET 0.

Second, the starting position of the PRG in the active BWP is related to the update indication information of the target CORESET and the system information block.

In this manner, in scenario one, when at least part of the update indication information is configured on the target CORESET, the starting position of the PRG is determined according to the minimum resource block index of the target CORESET. Specifically, when the current active BWP of the terminal overlaps with at least part of the frequency domain resources of the initial BWP, if the terminal receives the update indication information indicating that at least part of the system information block is configured on the target CORESET, the terminal determines the start position of the PRG in the active BWP according to the target CORESET, thereby determining the division result of the PRG in the active BWP, and receives the system message block sent by the network device according to the division result of the PRG.

Specifically, in this scenario the starting position of the PRG is determined according to the smallest resource block index of the target CORESET, such as CORESET 0. As shown in fig. 3-5, the starting position of the PRG in the activated BWP may be the starting position of CORESET0, and the frequency domain starting point of CORESET0 may be the same as the frequency domain starting point of the initial BWP.

That is, in the case that the frequency domain resources of the active BWP of the terminal overlap with the frequency domain resources of the initial BWP, if the network device indicates that the terminal needs to update the system information, after the terminal acquires the update indication information of the updated system information, if the update indication information indicates that at least part of the system information block is configured on the target CORESET, the terminal assumes that the starting position of the PRG partition in the active BWP is the starting point of CORESET 0.

On the other hand, in this manner, in scenario two, when the update indication information is not configured on the target CORESET, the starting position of the PRG is determined according to the component carrier CC where the BWP is activated. Specifically, when the current active BWP of the terminal overlaps with at least part of the frequency domain resources of the initial BWP, if the terminal receives the update indication information indicating that the system information block is not configured on the target CORESET, the terminal determines the start position of the PRG in the active BWP according to the CC where the active BWP is located, thereby determining the partition result of the PRG in the active BWP, and receives the system message block sent by the network device according to the partition result of the PRG.

Specifically, in this scenario two, the starting position of the PRG is determined according to the minimum resource block index of the CC. As shown in fig. 6, when the activation BWP is BWP1, BWP2, BWP3 or BWP4, the starting position of PRG in the activation BWP may be CC 1.

That is to say, under the condition that the frequency domain resources of the active BWP of the terminal overlap with the frequency domain resources of the initial BWP, if the network device indicates that the terminal needs to update the system information, after the terminal acquires the update indication information of the updated system information, and if the update indication information indicates that the system information block is not configured on the target CORESET, the terminal assumes that the starting position of the PRG partition in the active BWP is the starting point of the CC where the active BWP is located.

The above has been briefly described with respect to the first and second ways to activate the starting position of PRG in BWP, respectively, and the following description of the embodiment will further describe the related indication information for updating the system information block.

In the embodiment of the present invention, the update indication information is carried in a Physical Downlink Control Channel (PDCCH), that is, the network device indicates, through the PDCCH, that the terminal needs to update the system information.

Further, the PRG in the BWP is a PRG for activating a Physical Downlink Shared Channel (PDSCH) on the BWP, and the PDSCH is scheduled by the PDCCH.

Taking the first method as an example, when the frequency domain resources of the active BWP of the terminal overlap with the frequency domain resources of the initial BWP, if the network device indicates that the terminal needs to update the system information through the PDCCH, after receiving the PDCCH, the terminal assumes that the starting point of PRG partition of the PDSCH carrying the system information block scheduled by the PDCCH starts from the minimum resource block index of CORESET indicated by the PBCH (that is, the starting point of CORESET0 starts).

Taking the second method as an example, when the frequency domain resources of the active BWP of the terminal overlap with the frequency domain resources of the initial BWP, if the network device indicates that the terminal needs to update the system information through the PDCCH, and after the terminal receives the PDCCH, if the PDCCH indicates that at least part of the system information block is configured on the target CORESET, the terminal assumes that the starting point of PRG division of the PDSCH carrying the system information block scheduled by the PDCCH starts from the minimum resource block index of the CORESET indicated by the PBCH (that is, the starting point of CORESET 0). If the PDCCH indicates that the system information block is not configured on the target CORESET, the terminal assumes that the starting point of PRG division of the PDSCH carrying the system information block scheduled by the PDCCH is from the minimum resource block index of the CC where the BWP is activated.

In the system transmission method according to the embodiment of the present invention, the network device or the terminal transmits the system information block according to the starting position of the PRG in the active BWP, where the starting position of the PRG is related to the target CORESET and the indication information of the system information block, so that different terminals using overlapping frequency domain resources can share the system information block.

The above embodiments respectively describe in detail the system information transmission methods in different scenarios, and the following embodiments further describe the corresponding communication devices with reference to the accompanying drawings.

As shown in fig. 7, the communication device 700 according to the embodiment of the present invention can implement the details of the method for transmitting the system information block according to the starting position of the PRG in the active BWP when the system information block is scheduled by the active bandwidth part BWP, where the starting position of the PRG is related to at least one of the target control resource set CORESET and the update indication information of the system information block, and the active BWP overlaps at least part of the frequency domain resources of the initial BWP, and achieves the same effect. The network device 700 specifically includes the following functional modules:

a transmission module 710, configured to transmit the system information block according to a starting position of a pre-coding resource block group PRG in the active bandwidth part BWP in case that the system information block is scheduled by the active bandwidth part BWP; wherein the starting position of the PRG is related to at least one of a target control resource set CORESET and update indication information of the system information block, and the active BWP overlaps at least part of frequency domain resources of the initial BWP.

Wherein, the starting position of the PRG is determined according to the minimum resource block index of the target CORESET.

When at least part of the updating indication information is configured on the target CORESET, the starting position of the PRG is determined according to the minimum resource block index of the target CORESET;

wherein, when the update indication information is not configured on the target CORESET, the starting position of the PRG is determined according to the component carrier CC where the active BWP is located.

Wherein, the starting position of the PRG is determined according to the smallest resource block index of the CC where the BWP is activated.

Wherein, the updating indication information is carried in the physical downlink control channel PDCCH.

The PRG is a PRG for activating a PDSCH (physical downlink shared channel) on the BWP, and the PDSCH is scheduled by the PDCCH.

The communication equipment is network equipment or a terminal.

It is noted that the communication device according to the embodiment of the present invention transmits the system information block according to the starting position of the PRG in the active BWP, the starting position of the PRG being related to the target CORESET and the indication information of the system information block, so that different terminals using overlapping frequency domain resources can share the system information block.

It should be noted that the division of the modules of the above communication device is only a logical division, and the actual implementation may be wholly or partially integrated into one physical entity, or may be physically separated. And these modules can be realized in the form of software called by processing element; or may be implemented entirely in hardware; and part of the modules can be realized in the form of calling software by the processing element, and part of the modules can be realized in the form of hardware. For example, the determining module may be a processing element separately set up, or may be implemented by being integrated in a chip of the apparatus, or may be stored in a memory of the apparatus in the form of program code, and the function of the determining module is called and executed by a processing element of the apparatus. Other modules are implemented similarly. In addition, all or part of the modules can be integrated together or can be independently realized. The processing element described herein may be an integrated circuit having signal processing capabilities.

For example, the above modules may be one or more integrated circuits configured to implement the above methods, such as: one or more Application Specific Integrated Circuits (ASICs), or one or more microprocessors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs), etc. For another example, when some of the above modules are implemented in the form of a Processing element scheduler code, the Processing element may be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor that can invoke the program code. As another example, these modules may be integrated together, implemented in the form of a system-on-a-chip (SOC).

Embodiments of the present invention also provide a computer-readable storage medium, on which a computer program is stored, where the computer program, when executed by a processor, implements the steps of the system information transmission method described above.
