Method for resource allocation, network equipment and terminal equipment

The present application claims the priority of the chinese patent office filed on 30/10/2017, the application number PCT/CN2017/108421, the application number PCT patent application entitled "method for resource allocation, network device and terminal device", and the application number PCT patent application filed on 25/4/2018, the application number PCT/CN2018/084497, the application number PCT patent application entitled "method for resource allocation, network device and terminal device", which are all incorporated herein by reference.

Technical Field

The present application relates to the field of communications, and in particular, to a method, a network device, and a terminal device for resource allocation.

Background

In a vehicle to X (V2X) scenario, a network device may indicate a reception resource pool to a terminal device through a System Information Block (SIB), where the reception resource pool is used for the terminal device to communicate with other terminal devices.

Specifically, when the network device configures a receiving resource pool for the terminal device, the network device may indicate the receiving resource pool through an SIB, where a synchronization reference source (sync reference) corresponding to the receiving resource pool may be determined by the terminal device according to a synchronization reference signal sent by the network device. However, when the network device does not configure multiple receiving resource pools for the terminal device, for example, the multiple receiving resource pools correspond to different synchronization reference sources, and the different synchronization reference sources may be determined by the terminal device according to reference signals of different network devices, due to size limitation of the SIB, it may not be possible to indicate all receiving resource pools through the SIB.

In addition, the network device may also transmit parameter information to the terminal device through the SIB, and specifically, the SIB may include a plurality of parameters used by at least one terminal device in the sidelink communication, but the plurality of parameters of all terminal devices may not be transmitted through the SIB due to size limitation of the SIB. Moreover, when the terminal device supports multiple working modes, for example, when a high-version terminal device is compatible with a low-version working mode, the network device further needs to determine the working mode of the terminal device, and further sends information including corresponding parameters to the terminal device, so that the terminal device lacks flexibility in selecting the working mode in sidelink communication.

Fig. 1 shows a schematic flow diagram of a method 100 for resource allocation according to an embodiment of the application, which method 100 may be performed by a network device. As shown in fig. 1, the method 100 includes: s110, a network device allocates a plurality of receiving resource pools for a terminal device, the plurality of receiving resource pools correspond to different synchronous reference sources, and the plurality of receiving resource pools are used for the terminal device to receive data sent by other terminal devices; s120, the network device determines at least one receiving resource pool in the plurality of receiving resource pools; s130, the network device sends an SIB to the terminal device, where the SIB is used to indicate the at least one reception resource pool.

In this embodiment, a network device allocates a plurality of receiving resource pools to a terminal device, where the plurality of receiving resource pools may correspond to a plurality of synchronization reference sources, and the plurality of synchronization reference sources are different synchronization reference sources. Optionally, the multiple receiving resource pools may correspond to the multiple synchronization reference sources one to one, that is, no receiving resource pool corresponding to the same synchronization reference source exists in the multiple receiving resource pools.

In this embodiment of the present application, the network device determines at least one receiving resource pool indicated by the SIB in the multiple receiving resource pools, and optionally, the network device may determine the at least one receiving resource pool in the multiple receiving resource pools according to different synchronization reference sources corresponding to the multiple receiving resource pools, or the network device may further determine the at least one receiving resource pool in the multiple receiving resource pools according to the number of the multiple receiving resource pools.

It should be understood that, considering that for a terminal device in an idle state, a reception resource pool of the terminal device cannot be indicated through dedicated Radio Resource Control (RRC) signaling, the terminal device in the idle state may be indicated through an SIB. However, due to the size limitation of the SIB, the reception resource pool allocated by the network device for the terminal device may not be completely indicated by the SIB, and therefore, it may be considered that the multiple reception resource pools are indicated by the SIB together with dedicated RRC signaling. Specifically, for the other receiving resource pools of the plurality of receiving resource pools determined by the network device except for the at least one receiving resource indicated by the SIB, the network device may indicate the other receiving resource pools through dedicated RRC signaling. Optionally, the synchronization reference source corresponding to at least one reception resource pool indicated by the SIB is different from the synchronization reference source corresponding to another reception resource pool indicated by the RRC.

Optionally, as an embodiment, the multiple receiving resource pools may include a first receiving resource pool, where the first receiving resource pool corresponds to a first synchronization reference source, and the first synchronization reference source corresponds to a synchronization reference signal sent by a network device that sends a BIS, that is, the terminal device may determine the first synchronization reference source according to the synchronization reference signal sent by the network device. Optionally, the network device may indicate the first reception resource pool through an SIB, that is, at least one reception resource pool indicated by the SIB includes the first reception resource pool, and the first reception resource pool is not indicated using dedicated RRC signaling.

Optionally, as an embodiment, the multiple receiving resource pools may include a Global Navigation Satellite System (GNSS) receiving resource pool, where the GNSS receiving resource pool corresponds to a GNSS synchronization reference source, and the GNSS synchronization reference source corresponds to a GNSS signal sent by a GNSS, that is, the terminal device may determine the GNSS synchronization reference source according to the synchronization signal sent by the GNSS. Optionally, the network device may indicate the GNSS reception resource pool through an SIB, that is, at least one reception resource pool indicated by the SIB includes the GNSS reception resource pool, and does not indicate the GNSS reception resource pool using dedicated RRC signaling.

Optionally, the GNSS receiving resource pool may be a Global Positioning System (GPS) receiving resource pool, and correspondingly, the GPS receiving resource pool corresponds to a GPS synchronous reference source, and the GPS synchronous reference source corresponds to a GPS signal sent by a GPS, that is, the terminal device may determine the GPS synchronous reference source according to the GPS signal sent by the GPS.

It should be understood that when only the first reception resource pool or only the GNSS reception resource pool is included in the plurality of reception resource pools, the network device may indicate the first reception resource pool or the GNSS reception resource pool only through the SIB. When the first receiving resource pool and the GNSS receiving resource pool are included in the plurality of receiving resource pools, the network device may indicate the first receiving resource pool and the GNSS receiving resource pool only through an SIB; alternatively, the first receiving resource pool and the GNSS receiving resource pool are indicated together through an SIB and dedicated RRC signaling, for example, the first receiving resource pool is indicated through an SIB and the GNSS receiving resource pool is indicated through dedicated RRC signaling, or the GNSS receiving resource pool is indicated through an SIB and the first receiving resource pool is indicated through dedicated RRC signaling, but the embodiment of the present application is not limited thereto.

Optionally, as an embodiment, the multiple receiving resource pools may further include at least one second receiving resource pool, where the at least one second receiving resource pool corresponds to at least one second synchronization reference source, and the at least one second receiving resource pool may correspond to the at least one second synchronization reference source in a one-to-one manner. The at least one second synchronization reference source corresponds to a synchronization reference signal sent by at least one neighboring network device of the network device, that is, the terminal device determines the at least one synchronization reference source according to the synchronization reference signal sent by the at least one neighboring network device. Optionally, the network device may indicate the at least one second reception resource pool through dedicated RRC signaling; alternatively, the network device may also indicate through the SIB, for example, when the number of the at least one second receiving resource pool is smaller, the network device may also indicate through the SIB; or when the number of the at least one second receiving resource pool is larger, the network device indicates the at least one second receiving resource pool together through the SIB and the dedicated RRC signaling, but the SIB and the second receiving resource pool indicated by the dedicated RRC signaling correspond to different synchronization reference sources.

Optionally, as an embodiment, considering the limitation of the SIB size, the number of the reception resource pools indicated by the SIB is limited, so that the network device may determine, according to the number of the multiple reception resource pools allocated to the terminal device, at least one reception resource pool indicated by the SIB in the multiple reception resource pools. Specifically, when the number of the multiple receiving resource pools is less than or equal to a preset value, the network device indicates all the multiple receiving resource pools through the SIB, that is, the number of at least one receiving resource pool indicated by the SIB is equal to the number of the multiple receiving resource pools. When the number of the multiple reception resource pools is greater than the preset value, the network device may indicate the multiple reception resource pools through an SIB and dedicated RRC together, that is, at least one reception resource pool indicated by the SIB is a partial reception resource pool in the multiple reception resource pools, the number of the at least one reception resource pool is less than the number of the multiple reception resource pools, and for other reception resource pools in the multiple reception resource pools except for the at least one reception resource pool indicated by the SIB, the network device may indicate through dedicated RRC signaling.

It should be understood that, when the number of the multiple receiving resource pools is greater than the preset value, if the multiple receiving resource pools include a first receiving resource pool and/or a GNSS receiving resource pool and the multiple receiving resources further include at least one second receiving resource pool, the SIB preferentially indicates the first receiving resource pool and/or the GNSS receiving resource pool, and if the size of the SIB allows, the SIB may further indicate a part of the receiving resource pools in the at least one second receiving resource pool, and indicate other second receiving resource pools through dedicated RRC signaling.

It should be understood that, when the network device indicates multiple reception resource pools together through the SIB and the dedicated RRC signaling, the synchronization reference source corresponding to the reception resource pool indicated by the SIB is different from the synchronization reference source corresponding to the reception resource pool indicated by the dedicated RRC signaling, that is, there is no reception resource pool corresponding to the same synchronization reference source as the reception resource pool indicated by the dedicated RRC signaling in the reception resource pool indicated by the SIB.

It should be understood that the preset value may be set according to an actual application, for example, may be determined according to the size of the SIB, and the embodiment of the present application is not limited thereto.

Therefore, in the method for resource allocation in the embodiment of the present application, the network device configures a plurality of receiving resource pools for the terminal device, and determines the receiving resource pool indicated by the SIB according to the synchronization reference sources corresponding to the plurality of receiving resource pools, so as to avoid that the terminal device in an idle state cannot be indicated only by dedicated RRC signaling; in addition, a plurality of receiving resource pools allocated for the terminal equipment can be indicated by the SIB and the dedicated RRC signaling together, so that the size limitation of the SIB is avoided, and the flexible configuration of the receiving resource pools is realized.

In addition, when the working version of the first terminal device is lower than that of the second terminal device, correspondingly, for the second terminal device working at the high version, the second terminal device may only support R15 and is incompatible with R14, or the second terminal device may support both R14 and R15, that is, the second terminal device is compatible with both high and low working versions.

The following describes in detail the relationship between the first SIB and the second SIB when the at least one terminal device includes the first terminal device and the second terminal device described above, with reference to several specific embodiments.

Correspondingly, the first terminal device receives the first SIB, determines the first parameter according to the first SIB, and performs identifier mapping only according to the first parameter, so that the first terminal device performs communication with the network device or performs sidelink communication with other terminal devices according to the identifier mapped by the first parameter. For example, the first terminal device and the network device may map the first parameter to a first identifier based on the same mapping rule, and the first terminal device and the network device communicate with each other using the first identifier.

Similarly, the second terminal device receives the second SIB, determines the first parameter corresponding to the first format and/or the second format according to the second SIB, and performs identifier mapping according to the first parameter, and the second terminal device performs communication with the network device or performs sidelink communication with other terminal devices according to the identifier mapped by the second parameter. For example, the second terminal device and the network device may map the second parameter to the second identifier based on the same mapping rule, and the second terminal device and the network device communicate with each other using the second identifier.

For example, taking the first parameter as the sidelink operating frequency of the terminal device as an example, and assuming that the first terminal device only supports the first format and the second terminal device supports the first format and the second format, the first SIB determined by the network device includes the sidelink operating frequency corresponding to the first format of the first terminal device, the second SIB includes the sidelink operating frequency corresponding to the first format of the second terminal device and the sidelink operating frequency corresponding to the second format, and the network device sends the first SIB and the second SIB to the two terminal devices, so that the first terminal device determines the sidelink operating frequency corresponding to the first format thereof according to the first SIB and performs identification mapping according to the sidelink operating frequency; and the second terminal equipment determines the side link working frequency corresponding to the first format and the side link working frequency corresponding to the second format according to the second SIB, and performs identification mapping according to the side link working frequencies corresponding to the first format and the second format.

Optionally, as an embodiment, the network device sends a first SIB and a second SIB to the first terminal device and the second terminal device, and correspondingly, the terminal device receives the first SIB and the second SIB, and the first terminal device may determine a second parameter of the at least one parameter according to the first SIB; the second terminal device may determine the second parameter according to the first SIB and the second SIB, where an index of the second parameter included in the first SIB received by the second terminal device is different from an index of the second parameter included in the second SIB, the second parameter is any one of the at least one parameter, and the second parameter is different from the first parameter.

Specifically, if the first terminal device only supports the first format, the first SIB includes a second parameter corresponding to the first format of the first terminal device; if the second terminal device only supports the second format, the first SIB includes a second parameter corresponding to the second format of the second terminal device, and meanwhile the second SIB includes a second parameter corresponding to the second format of the second terminal device; if the second terminal device supports the first format and the second format, the first SIB includes a second parameter corresponding to the first format of the second terminal device and/or a second parameter corresponding to the second format, and the second SIB includes a second parameter corresponding to the second format of the second terminal device, or may also include a second parameter corresponding to the first format of the second terminal device. The second parameter corresponding to the first format of the first terminal device included in the first SIB, the second parameter corresponding to the first format of the second terminal device included in the first SIB, and/or the second parameter corresponding to the second format, the second parameter corresponding to the first format of the second terminal device included in the second SIB, and the second parameter corresponding to the second format may be the same or different, and embodiments of the present application are not limited thereto.

Correspondingly, the first terminal device receives the first SIB, determines the second parameter according to the first SIB, and performs identifier mapping only according to the second parameter, so that the first terminal device performs communication with the network device or performs sidelink communication with other terminal devices according to the identifier mapped by the second parameter. For example, the first terminal device and the network device may map the second parameter to the first identifier based on the same mapping rule, and the first terminal device and the network device communicate with each other using the first identifier.

And the second terminal equipment receives the first SIB and the second SIB, determines a second parameter corresponding to the first format and/or the second format according to the first SIB and the second SIB, and performs identifier mapping according to the second parameter determined by the first SIB and the second SIB. Wherein, the second terminal device may map the second parameters determined by the first SIB and the second SIB to the same or different identities, for example, if the second parameters determined by the first SIB and the second SIB are for the same carrier, the second parameters determined by the first SIB and the second parameters determined by the second SIB may be mapped to the same identities; if the second parameters determined by the first SIB and the second SIB are for different carriers, the second parameters determined by the first SIB and the second parameters determined by the second SIB may be mapped to different identities, which is not limited in this embodiment of the present application. For example, the second terminal device maps the second parameter determined by the first SIB to the first identifier and maps the second parameter determined by the second SIB to the second identifier, so that the second terminal device communicates with the network device or communicates with other terminal devices in a sidelink manner using the first identifier and/or the second identifier. For example, the second terminal device and the network device perform mapping based on the same mapping rule, map the second parameter determined by the first SIB to the first identifier, and map the second parameter determined by the second SIB to the second identifier, so that the second terminal device communicates with the network device using the first identifier and/or the second identifier.

For example, taking the second parameter as an example of a receiving resource pool parameter of a terminal device, and assuming that a first terminal device supports a first format and a second terminal device supports the first format and the second format, a first SIB determined by a network device includes the receiving resource pool parameter corresponding to the first format of the first terminal device, and at the same time, the first SIB further includes the receiving resource pool parameter corresponding to the first format and/or the second format of the second terminal device, and the second SIB determined by the network device includes the receiving resource pool parameter corresponding to the second format of the second terminal device, or the second SIB includes the first format of the second terminal device and the receiving resource pool parameter corresponding to the second format, and the network device sends the first SIB and the second SIB to the two terminal devices so that the first terminal device determines the receiving resource pool parameter corresponding to the first format thereof according to the first SIB, and mapping the identifier according to the receiving resource pool parameter; the second terminal device determines the receiving resource pool parameter corresponding to the first format and the receiving resource pool parameter corresponding to the second format according to the first SIB and the second SIB, and performs identifier mapping respectively according to the receiving resource pool parameters determined by the first SIB and the second SIB, where an identifier mapped by the receiving resource pool parameter determined by the first SIB and an identifier mapped by the receiving resource pool parameter determined by the second SIB may be the same or different.

Optionally, as an embodiment, the network device may further send a first SIB to the first terminal device and the second terminal device, the terminal device receives the first SIB, the first terminal device determines a third parameter of the at least one parameter according to the first SIB, and the second terminal device determines the third parameter according to the first SIB, where the third parameter may be any one of the at least one parameter of the sidelink communication, and the third parameter is different from the first parameter and the second parameter.

Specifically, if the first terminal device only supports the first format, the first SIB includes a third parameter corresponding to the first format of the first terminal device; if the second terminal device only supports the second format, the first SIB further includes a third parameter corresponding to the second format of the second terminal device; if the second terminal device supports the first format and the second format, the first SIB includes a third parameter corresponding to the first format and a third parameter corresponding to the second format of the second terminal device. The third parameter corresponding to the first format of the first terminal device included in the first SIB, the third parameter corresponding to the first format of the second terminal device included in the first SIB, and the third parameter corresponding to the second format may be the same or different.

Correspondingly, the first terminal device receives the first SIB, determines the third parameter according to the first SIB, and performs identifier mapping only according to the third parameter, so that the first terminal device performs communication with the network device or performs sidelink communication with other terminal devices according to the identifier mapped by the third parameter. For example, the first terminal device and the network device may map the third parameter to the first identifier based on the same mapping rule, and the first terminal device and the network device communicate with each other using the first identifier.

Similarly, the second terminal device also receives the first SIB, determines a third parameter corresponding to the first format and/or the second format according to the first SIB, and performs identifier mapping according to the third parameter determined by the first SIB, so that the second terminal device communicates with the network device or performs sidelink communication with other terminal devices according to an identifier mapped by the third parameter. For example, the second terminal device and the network device may map the third parameter to the second identifier based on the same mapping rule, and the second terminal device and the network device communicate with each other using the second identifier.

For example, taking the first parameter as an example of a transmission resource pool parameter of a terminal device, and assuming that a first terminal device only supports a first format and a second terminal device supports the first format and the second format, a first SIB determined by a network device includes the transmission resource pool parameter corresponding to the first format of the first terminal device, and also includes the transmission resource pool parameter corresponding to the first format of the second terminal device and the transmission resource pool parameter corresponding to the second format, and the network device transmits the first SIB to the two terminal devices, so that the first terminal device determines the transmission resource pool parameter corresponding to the first format thereof according to the first SIB, and performs identification mapping according to the resource pool parameter; and the second terminal equipment determines the transmission resource pool parameters corresponding to the first format and the transmission resource pool parameters corresponding to the second format according to the first SIB, and respectively carries out identifier mapping according to the resource pool parameters determined by the first SIB.
