Description

Resource allocation method, terminal communication method and related equipment

Technical Field

The present application relates to the field of electricity, and in particular, to a resource allocation method, a terminal communication method, and a related device.

Background

The Device to Device (D2D) technology defined by the 3rd Generation Partnership Project (3 GPP) protocol is a technology for direct communication between devices, i.e., messages and corresponding control information may be sent directly between two devices without going through a base station. Currently, the D2D technology defined by the 3GPP protocol is mainly a public safety oriented application, in which a Physical bypass discovery channel (PSDCH) channel for sending a discovery message (discovery message) is defined.

In a typical application scenario, in a Relay (UE-to-Network Relay) scenario from a User Equipment (UE) to a Network, data and control information between an evolved Node B (eNB) and a Remote Equipment (Remote User Equipment, Remote UE) are transferred through the Relay Equipment (Relay User Equipment, Relay UE). In the D2D technology defined by the 3GPP protocol, both the transmitting device and the receiving device support full bandwidth operation. For example, when the system bandwidth is 20MHz, the device may transmit and receive discovery messages on the 20MHz frequency band.

In the prior art, a relay device selects a resource for transmitting a discovery message in a full frequency band at a time interval, and the selected resource can hop in a full frequency band, so that a remote device needs to receive and demodulate signals in the full frequency band over the entire operating bandwidth. This approach may increase the power consumption of the remote device.

Detailed Description

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In the present application, the network side device is not limited to the eNB, the Node B, and the Base Station (BS), but may also include other radio access network side devices associated with the eNB, the Node B, and the Base Station (BS) to complete a certain function.

The embodiment of the present application can be applied to the system architecture shown in fig. 1, where fig. 1 describes a relay scenario from a user equipment to a network, where a relay terminal is in a network coverage of an eNB, and the relay terminal and the eNB communicate through a Uu link; the Remote terminals may be within the network coverage of the eNB, such as Remote UE1 shown in fig. 1, or outside the network coverage of the eNB, such as Remote UE2 shown in fig. 1, and each Remote terminal and the relay terminal communicate through a bypass link.

A discovery message sent by a relay terminal (relay UE) to a remote terminal is sent in a discovery resource pool, and the discovery resource pool is divided into a plurality of time-frequency resource sets according to a period, where the period is referred to as a discovery period. In order to improve the reliability of the remote terminal receiving the discovery message, in each discovery period, the relay terminal can send the discovery message carrying the same information for at most 4 times, including 1 time of primary transmission and 3 times of retransmission. As shown in fig. 2.a, configuring the discovery period to 320ms, the relay device may select a resource on the PSDCH resource set for sending the discovery message. As shown in fig. 2.b, the relay device randomly selects one resource from the resource set in one period of the PSDCH for sending the discovery message.

Referring to fig. 3, a flow of an embodiment of the present application is described below, where a method embodiment of a resource allocation method and a terminal communication method in the embodiment of the present application includes:

301. the network side equipment divides the available bandwidth into at least two sub-bands;

in the D2D technique, a first terminal selects a resource on an available bandwidth to transmit a first message, wherein the available bandwidth is a frequency band used for the first terminal and a second terminal to communicate. The network side device divides the available bandwidth to obtain at least two sub-bands, where the at least two sub-bands include a primary sub-band and at least one secondary sub-band, and the manner in which the network side device divides the available bandwidth may be equal division or unequal division, that is, the bandwidths of the sub-bands obtained by division may be the same or different, and are not limited herein.

In addition, the network side device may divide the available bandwidth according to the supportable bandwidth of the second terminal, for example, the bandwidth supported by the second terminal is narrower, and correspondingly, the network side device divides the available bandwidth into sub-bands with smaller bandwidths. In practical applications, there are various bases for the network side device to divide the available bandwidth, for example, if the network device determines that the number of the second terminals is N, the network device divides the available bandwidth into N +1 shares, where the available bandwidth may include 1 primary subband and N secondary subbands, and therefore the base for the network side device to divide the available bandwidth is not limited herein.

It should be noted that for convenience of description, a "subband" is used in this application to refer to a resource set obtained by dividing an available bandwidth in a frequency domain, and it is understood that a subband includes a resource set of a certain frequency resource and a certain time resource. A subband may include one or more subcarriers in frequency, one or more PRBs with larger granularity in frequency, and even one or more carrier frequency resources. In practical applications, a subband may also be referred to as a subchannel, a time-frequency resource set, or a subband, and is not limited herein.

Optionally, dividing the available bandwidth into one or more sub-bands may also be performed in a preconfigured manner, i.e., without requiring the network side device to divide the available bandwidth.

302. Configuring resource configuration information by the network side equipment;

after the network side device divides the available bandwidth to obtain a primary sub-band and at least one secondary sub-band, resource configuration information is configured, where the resource configuration information at least includes information of the primary sub-band, and the information of the primary sub-band may specifically include at least one of the following information: the offset of the main subband resource from the SFN starting position or the DFN starting position in the time domain, the resource period on the main subband, the time domain resource contained in each resource period on the main subband, the position of the main subband in the frequency domain, and the resource size occupied by the main subband in the frequency domain. It should be noted that all the information required for determining the primary subband includes an offset between the primary subband resource and the SFN starting position or the DFN starting position in the time domain, a resource period on the primary subband, a time domain resource included in each resource period on the primary subband, a position of the primary subband in the frequency domain, and a resource size occupied by the primary subband in the frequency domain, and if the information of the primary subband includes only part of the information in the entire information, other information in the entire information can be obtained in the preconfigured information. Optionally, the resource configuration information may further include information of a secondary sub-band, where the information of the secondary sub-band may be specific information or mapping relationship of the secondary sub-band. When the information of the sub-band is specific information of the sub-band, at least one of the following information is included: the position of the time-frequency domain resource of the sub-subband, the size of the resource occupied by the sub-subband in the frequency domain, the transmission period of the signal on the sub-subband, and the like.

It is understood that the resource configuration information may include, in addition to the information of the primary subband, information of a terminal receiving resource pool (for example, a time-frequency resource location of the resource pool), a time period in which a resource on a target subband is available, and the like.

The primary (primary) sub-band and the secondary (secondary) sub-band are a relative concept in the present invention. The resource of the Relay UE for sending the message on the main subband is configured by a network side device such as eNB, and the resource used by the Relay UE for sending the message on the auxiliary subband has a certain association relation with the resource used on the main subband.

When the information of the sub-band is a mapping relation, the mapping relation is a relation between the resource of the main sub-band and the corresponding resource of the sub-band, such as a simple mapping relation listed in table 1, the serial number of the resource on the main sub-band is associated with the sub-band with the same serial number, assuming that the main sub-band comprises 6 PRBs, each time interval (in this application, the time interval refers to a fixed time unit; in the current LTE standard, the time interval length is equal to the time length of a sub-frame, i.e. the time interval can be represented by a sub-frame) two PRBs on the main sub-band constitute one resource block to obtain 3 resource blocks, the 3 resource blocks are respectively numbered as resource block 1, resource block 2 and resource block 3, the sub-bands are also numbered as sub-band 1 to sub-band 3, the resource blocks 1 to 3 on the main sub-band are respectively associated with sub-band 1, the first terminal subsequently transmits a signal on the resource on the sub-subband 1, which can be understood as the resource on the sub-subband is determined according to the configured resource location on the main subband.

TABLE 1

Sequence number of resource on main sub-band	Sub-band number
		Resource block
1	Subband 1
		Resource block 2	Subband 2
Resource block 3	Subband 3

In addition, when the network side device configures the mapping relationship, a dynamic configuration mode may also be adopted, that is, the mapping relationship may be changed, and therefore, the configuration mode of the mapping relationship is not limited here.

It is understood that the example in table 1 is to map the resource blocks on the primary subbands directly to the secondary subbands, that is, the resource blocks on one primary subband are mapped to a corresponding resource block set of one secondary subband; other mapping relations may also be that resources on the primary subband are mapped with resources on the secondary subband, for example, one or more resource blocks on the primary subband are mapped onto different resource block sets on one secondary subband, or N resource blocks on the primary subband are mapped onto L different resource block sets on M secondary subbands. In addition, resource blocks of different time intervals on the primary subband may be mapped to different time domain offsets or frequency domain offsets on the secondary subband, that is, the mapping relationship may also be an offset of resources mapped on the primary subband and the secondary subband in the time domain, that is, the location of the resources mapped on the secondary subband may be obtained according to the known location of the primary subband resource, and similarly, the mapping relationship may also be an offset of the resources mapped on the primary subband and the secondary subband in the frequency domain, so the content of the mapping relationship is not limited here.

It should be noted that, in this embodiment of the application, the network side device divides the available bandwidth into a plurality of sub-bands through step 301 and step 302, and configures the resource configuration information, in an actual application, both the division of the available bandwidth and the resource configuration information may be preconfigured, and a specific example is not limited here. In the embodiment of the application, the preconfigured information is information agreed according to a protocol.

303. The network side equipment sends resource configuration information through a broadcast channel;

the network side equipment sends the resource configuration information through a broadcast channel, so that the first terminal and a second terminal within the coverage range of the network side equipment both obtain the resource configuration information. The resource configuration information at least comprises information of a primary sub-band, and the primary sub-band can be determined through the information of the primary sub-band.

Optionally, when the resource configuration information further includes information of the secondary subband, the information of the secondary subband may be specific information of the secondary subband or a mapping relationship between the primary subband resource and the corresponding secondary subband resource. When the information of the secondary sub-band is a mapping relationship, the network side device may dynamically configure the mapping relationship, for example, the network side device sends a new mapping relationship through a broadcast channel every preset number of periods or preset times of resources on the primary sub-band or meeting a preset condition (for example, resource utilization information), so that the first terminal and the second terminal within the coverage of the network side device obtain the new mapping relationship.

304. The method comprises the steps that network side equipment receives a resource request sent by a first terminal;

the network side equipment receives a resource request sent by a first terminal, wherein the resource request is used for requesting the network side equipment to configure a resource used for sending a first message for the first terminal on an available bandwidth, so that the first terminal sends the first message to a second terminal through the resource.

It is understood that 303 and 304 are not strictly sequential and are determined by the network side device.

305. The network side equipment sends a first signaling to a first terminal;

after receiving a resource request sent by a first type terminal, a network side device sends a first signaling to a first terminal, wherein the first signaling is used for configuring a second target resource to the first terminal, and the second target resource is used for the first terminal to send a first message on a main subband.

Optionally, when the resource configuration information sent by the network side device only includes information of the primary subband, the first signaling may be further configured to configure, to the first terminal, a first target resource on a target secondary subband, where the first target resource is used for the first terminal to send the first message on the target secondary subband, and the first target resource is configured by the base station for the first terminal.

It should be noted that, the network side device configures the first target resource to the first terminal through the first signaling, where the configuration mode may be dynamic configuration, for example, the network side device periodically sends the first signaling again to the first terminal every other period of the resources on the preset number of main subbands, and the first signaling is used to configure a new first target resource to the first terminal.

306. A first terminal acquires resource configuration information;

since the first terminal needs to send the first message on the target subband, the first terminal needs to acquire the information of the target subband. When the target subband is the primary subband, the first terminal receives information of the primary subband, which is sent by the network side device through a broadcast channel, or the first terminal obtains the information of the primary subband in the preconfigured information, so the manner in which the first terminal obtains the information of the primary subband is not limited here.

Optionally, when the target subband further includes the target sub-subband, the corresponding resource configuration information further includes information of the target sub-subband. There are multiple ways for the first terminal to obtain the information of the target sub-band, including:

1. the first terminal acquires information of a target sub-band in the pre-configuration information, wherein the information of the target sub-band can be specific information or a mapping relation of the target sub-band; 2. the first terminal receives information of a target sub-subband, which is sent by a network side device through a broadcast channel, where the information of the target sub-subband may be specific information of a sub-subband or a mapping relationship, and it should be noted that, when the mapping relationship is configured by the network side device, the mapping relationship may be unchanged or dynamically changed, and is not limited herein specifically. Therefore, in practical applications, a specific manner for the first terminal to obtain the information of the target sub-band is not limited herein.

In this embodiment of the application, the first terminal may be a wireless terminal, an intelligent terminal, other terminals supporting sidelink, a relay terminal, and the like, and is not limited herein.

307. The first terminal determines a target resource;

after the first terminal obtains the resource configuration information, the target resource is determined, and then a first message is sent to the second terminal through the target resource. After receiving a first signaling sent by a network side device, a first terminal at least configures a second target resource on a primary subband to the first terminal, where the second target resource is used for the first terminal to send a first message on the primary subband.

Optionally, if the first terminal further sends the first message on the corresponding target subband, the target resource further includes a resource used by the first terminal to send the first message on the target subband, that is, the first target resource, so that the first terminal further needs to determine the first target resource. Because there are multiple ways and contents of the resource configuration information obtained by the first terminal, and multiple contents included in the first signaling, correspondingly, there are multiple ways for the first terminal to determine the first target resource, including:

firstly, a first terminal determines a first target resource through a first signaling and a mapping relation;

the first signaling is used for configuring a second target resource on the primary subband to the first terminal, so that through the first signaling, the first terminal determines the second target resource on the primary subband, and when the resource configuration information obtained by the first terminal includes a mapping relationship, the first terminal finds out a first target resource corresponding to the second target resource in the mapping relationship, wherein the mapping relationship is pre-configured or is sent by a network side device through a broadcast channel.

And determining the first target resource by the first terminal through the first signaling.

When the first signaling is further used for configuring a first target resource on a target secondary sub-band to the first terminal, the first terminal may directly obtain the first target resource from the first signaling, where the first target resource is configured by the network side device.

It can be understood that, when the first signaling is also used to configure the first target resource on the target secondary subband to the first terminal, since the first signaling is sent to the first terminal by the network side device and not sent to the second terminal, the second terminal does not know the first target resource, and in order to allow the second terminal to receive the first message sent by the first terminal using the first target resource, the first message sent by the first terminal on the primary subband carries indication information, where the indication information is used to indicate the first target resource to the second terminal.

Therefore, the manner in which the first terminal obtains the resource used for sending the first message on the target subband is not limited herein.

308. A first terminal sends a first message on a target subband through a target resource;

after determining a target resource, a first terminal sends a first message on the determined target resource, wherein when a target sub-band is a main sub-band, the target resource is a second target resource, and the second target resource is a resource used by the first terminal for sending the first message on the main sub-band.

When the target sub-band further includes the target sub-band, the target resource further includes a resource used by the first terminal to transmit the first message on the target sub-band, i.e., the first target resource. The first terminal therefore transmits the first message on the primary subband via the second target resource and transmits the first message on the target secondary subband via the first target resource. As shown in fig. 4, a schematic diagram of the first terminal periodically transmitting the first message on the primary subband and the secondary subband is shown, in which the available bandwidth is equally divided into 1 primary subband and 4 secondary subbands, and three first terminals, namely, Relay UE1, Relay UE2, and Relay UE3, all transmit a resource request to the network-side device, where the resource request is used to request the network-side device to configure a resource used for transmitting the first message. The network side equipment allocates three orthogonal resource blocks on a certain sub-frame of the main sub-band for the three first terminals, the three orthogonal resource blocks are respectively numbered as resource block 1-resource block 3, each first terminal periodically sends a first message on the main sub-band, and the resource blocks on the main sub-band and the sequence numbers of the sub-bands have a mapping relation, so that each first terminal respectively transfers to the corresponding sub-bands to send after sending the first message on the main sub-band, for example, after the Relay UE1 sends the first message on the main sub-band resource block 1, the Relay UE1 continues to periodically send at the position designated by the sub-band 1 for a period of time, and then the above processes are repeated.

309. The second terminal acquires resource configuration information;

the second terminal needs to receive the first message sent by the first terminal on the target sub-band, so the second terminal needs to acquire the information of the target sub-band. When the target subband is the primary subband, the second terminal receives information of the primary subband, which is sent by the network side device through a broadcast channel, or the second terminal obtains the information of the primary subband in the preconfigured information, and a manner of obtaining the information of the primary subband by the second terminal is not limited herein.

Optionally, when the target subband further includes the target sub-subband, the corresponding resource configuration information further includes information of the target sub-subband. There are multiple ways for the second terminal to obtain the information of the target sub-band, including:

1. the second terminal acquires information of a target sub-band in the pre-configuration information, wherein the information of the target sub-band can be specific information or a mapping relation of the target sub-band; 2. the second terminal receives information of a target sub-subband, which is sent by the network side device through a broadcast channel, where the information of the target sub-subband may be specific information of the sub-subband or a mapping relationship, and it should be noted that, when the mapping relationship is configured by the network side device, the mapping relationship may be unchanged or dynamically changed, and is not limited herein specifically. Therefore, in practical applications, the manner of acquiring the information of the target sub-band by the second terminal is not limited herein.

It can be understood that, in the embodiment of the present application, when the second terminal is outside the coverage of the network-side device, the second terminal cannot directly receive the message sent by the network-side device, so when the configuration information is sent by the network-side device through the broadcast channel, the configuration information is replaced by the pre-configuration information for the second terminal.

In this embodiment of the application, the second terminal may be a wearable device, an IoT device, other sidelink-enabled terminals, or a remote terminal, and the like, which is not limited herein.

310. The second terminal determines a master sub-band;

and after the second terminal acquires the resource configuration information, determining the master sub-band according to the information of the master sub-band included in the resource configuration information. The second terminal may determine the primary sub-band by its position in the frequency domain. It should be noted that, in practical applications, there are various ways for the second terminal to determine the primary subband, for example, if the resource configuration information further includes an identifier of the primary subband, the second terminal finds the primary subband according to the identifier of the primary subband, or the resource configuration message further includes an offset of the primary subband in the frequency domain from the fixed frequency domain, and the second terminal determines the primary subband according to the offset. Therefore, the manner in which the second terminal determines the subband is not limited herein.

311. The second terminal receives a first message sent by the first terminal on the main subband according to the resource configuration information;

after the second terminal determines the main subband, the second terminal may determine, on the main subband, the position information of the main subband resource through the offset of the main subband resource from the start position of the SFN or the DFN in the time domain in the resource configuration information and the period of the resource on the main subband, where the main subband resource is a resource used by the first terminal on the main subband, so that the second terminal receives, at a corresponding position on the main subband through the position information of the main subband resource, the first message sent by the first terminal, where it is to be noted that the first terminal may be multiple terminals.

312. The second terminal determines a target terminal;

after receiving a first message sent by a first terminal on a main subband, a second terminal demodulates the received first message to obtain information of the first terminal carried in the first message, such as information of a Public Land Mobile Network (PLMN) identifier, an identifier of the first terminal, and the like, and received signal strength of the first message, and selects the first terminal meeting a preset condition as a target terminal. For example, the second terminal selects the first terminal corresponding to the first message with the maximum received signal strength as the target terminal.

It should be noted that, in practical applications, there are various ways for the second terminal to determine the target terminal, for example, the second terminal obtains the comprehensive channel quality of the first terminal, and the comprehensive channel quality is a channel quality with a lower channel quality in the quality of the channel used by the first terminal for communication with the network side device and the quality of the channel used by the first terminal for communication with the second terminal user, and the second terminal determines the terminal with the highest comprehensive channel quality in the first terminal as the target terminal. For another example, the second terminal may select, as the target terminal, the first terminal that has the received signal strength of the first message exceeding the preset threshold and that has been associated with the second terminal. Therefore, the manner of determining the target terminal by the second terminal is not limited herein.

313. The second terminal determines a target sub-band;

after the second terminal determines the target terminal, a target sub-band corresponding to the target terminal needs to be determined, so as to receive the first message sent by the first terminal on the target sub-band. It should be noted that, in practical applications, there are various ways for the second terminal to determine the target sub-band, including:

the second terminal determines a target sub-band through the mapping relation between the main sub-band resource and the corresponding sub-band resource and the information of the main sub-band;

after the second terminal obtains the resource configuration information, if the resource configuration information includes the mapping relationship and the information of the primary subband, where the mapping relationship and the information of the primary subband are both obtained by the network side device through the broadcast channel transmission or obtained in the preconfigured information, the second terminal finds out the mapping relationship

The second terminal determines a target sub-band according to the indication information;

if the first message received by the second terminal on the primary subband carries indication information, and the indication information is used for indicating target resources on a target secondary subband, the target resources on the target secondary subband are resources for the first terminal to send the first message on the target secondary subband, and the indication information is added in the first message by the first terminal, so that the second terminal finds out the subband corresponding to the target resources on the target secondary subband as the target secondary subband.

And the second terminal determines the target sub-band according to the specific information of the target sub-band.

When the resource configuration information obtained by the second terminal includes specific information of a target sub-subband, where the target sub-subband information is preconfigured or is sent by a network side device through a broadcast channel, the specific information of the target sub-subband at least includes one of the following information: and the second terminal determines the target sub-subband according to the specific information of the target sub-subband.

314. The second terminal receives the first message at the target sub-band;

after the second terminal determines the target sub-subband, the second terminal correspondingly receives, on the target sub-subband according to the position of the first target resource, the first message sent by the first terminal, so as to measure the quality of the signal through the first message, where the first target resource is a resource used by the first terminal to send the first message on the target sub-subband, and the position of the first target resource may be preset, or obtained by the network side device through a broadcast channel, or determined through indication information carried by the first information sent by the first terminal on the main subband, where the indication information is used to indicate the position of the first target resource, and therefore, the obtaining mode of the position of the first target resource is not limited specifically here.

315. The second terminal measuring signal quality according to the first message received on the secondary sub-band;

the second terminal detects the first message received on the secondary sub-band, obtains an actual signal quality parameter of the first message, for example, the signal quality parameter is signal received power, and compares the actual signal received power with reference signal received power to measure the signal quality of the first terminal.

In practical applications, the second terminal may also measure the signal quality through a process of receiving the first information, for example, according to whether the bit error rate or the signal-to-noise ratio satisfies a reference value. Therefore, the measuring method is not limited herein.

316. The second terminal continues to receive the first message on the primary subband.

And if the signal strength of the target terminal is lower than the preset threshold value, the second terminal returns from the target sub-band to the main sub-band to continue receiving the first message, demodulates the received first message to re-determine a new target terminal, and jumps to the sub-band corresponding to the new target terminal to receive the first message sent by the first terminal until the signal strength of the new target terminal is determined to be higher than the preset threshold value.

It should be noted that, in practical applications, there are multiple triggering manners for triggering the second terminal to return to the primary sub-band, and the method further includes that the second terminal acquires a period instruction, where the period instruction may be preconfigured or sent by the network side device through a broadcast channel, where the period instruction is used to instruct the second terminal to perform periodic switching between the primary sub-band and the secondary sub-band, the second terminal continues to receive the first message on the primary sub-band through the period instruction, demodulates the received first message, selects a suitable (for example, the first terminal with the strongest signal strength) from the first message as a new target terminal, and then jumps to the secondary sub-band corresponding to the new target terminal to continue to receive the first message, and the cycle is repeated. Or setting a timer, and when the timer indicates that the set time length is reached, the second terminal continues to receive the first message on the main subband. Therefore, the triggering manner of the second terminal in the primary sub-band is not limited herein.

In the embodiment of the application, the network side device divides available bandwidth used for communication between the first terminal and the second terminal to obtain the main sub-band and the at least one auxiliary sub-band, and the first terminal sends the first message to the main sub-band and the auxiliary sub-band respectively, so that the load of the main sub-band can be reduced, and meanwhile, in-band leakage interference between the first terminals is also reduced.

If not specifically stated, there is no strict sequence between the steps in this embodiment, and the sequence may be determined by a signal trigger sent by the implementation subject of each step and/or other implementation subjects.

In the embodiment shown in fig. 3, the available bandwidth for communication between the first terminal and the second terminal is divided into one primary sub-band and at least one secondary sub-band, and in practical application, the available bandwidth may also be divided into a plurality of primary sub-bands and a plurality of secondary sub-bands, specifically as shown in fig. 5, another embodiment of the resource allocation method and the terminal communication method in this embodiment of the present application includes:

It should be noted that, the sub-bands corresponding to the same bandwidth may be in a continuous frequency domain resource position or a discontinuous frequency domain resource position in the division manner, and the specific details are not limited herein.

In addition, in practical applications, the sub-bands with different bandwidths may all be divided in the time domain, or all be divided in the frequency domain, and the sub-bands with different bandwidths may also be divided in a time division multiplexing manner, as shown in fig. 7, when the sub-band with the 6PRB bandwidth and the sub-band with the 1PRB bandwidth coexist in the available bandwidth, the sub-band with the 6PRB bandwidth may be divided in the time domain within a certain frequency band, and the sub-band with the 1PRB bandwidth may be divided in the frequency domain within a certain time interval, so the specific division manner is not limited here.

502. Configuring resource configuration information by the network side equipment;

after dividing the available bandwidth, the network side device configures resource configuration information, where the resource configuration information at least includes information of each primary subband, and the information of each primary subband may specifically include at least one of the following information: the offset of the main subband resource from the SFN starting position or the DFN starting position in the time domain, the time domain resource contained in each resource period on the main subband, the period of the resource on the main subband, the position of the main subband in the frequency domain, and the resource size occupied by the main subband in the frequency domain.

When the information of each sub-subband is a mapping relationship, in this embodiment, there are at least two mapping relationships, that is, a relationship between a first main subband resource and a corresponding first sub-subband resource, and a relationship between a second main subband resource and a corresponding second sub-subband resource, and the two mapping relationships are transmitted by the network side device through a broadcast channel.

It can be understood that the resource configuration information may include, in addition to the information of the primary subband, information of a terminal receiving resource pool (for example, a time-frequency resource location of the resource pool), a time period during which a resource on a target subband is available, and the like, which is not limited herein.

For convenience of understanding, as shown in fig. 8, which is a schematic diagram of periodically transmitting a first message by a first relay terminal and a second relay terminal, in fig. 8, an available bandwidth is divided into 2 primary subbands and a plurality of secondary subbands, and the primary subbands include both primary subbands of 6PRB bandwidths and primary subbands of 1PRB bandwidth. Likewise, a sub-subband may include both sub-subbands of 6PRB bandwidths and sub-subbands of 1PRB bandwidth. Three first Relay terminals Relay UE1, Relay UE2 and Relay UE3 with 6PRB working bandwidth send resource requests to network side equipment for sending first messages, and the network side equipment allocates three orthogonal resource blocks for the three first Relay terminals at a certain time interval of a main sub-band with 6PRB bandwidth, wherein the three orthogonal resource blocks can be respectively numbered as resource block 1-resource block 3; three second Relay terminals, namely, Relay UE 4, Relay UE 5 and Relay UE 6, with working bandwidth of 1PRB send resource requests to network side equipment to send first messages, the network side equipment may number resource blocks 4 to resource block 6 of three consecutive subframes with the same frequency domain position at a certain time interval of a primary subband with 1PRB bandwidth for the three second Relay terminals, each Relay terminal periodically sends a first message on the corresponding primary subband, and the resource blocks on the primary subband with 6PRB bandwidth have mapping relation with the sequence number of the corresponding secondary subband, so that the Relay terminals 1 to 3 transmit the first messages on the primary subband with 6PRB bandwidth and then respectively transfer to the corresponding secondary subbands with 6PRB bandwidth to send the first messages. For example, after the Relay UE1 transmits the first message on resource block 1, it continues to periodically transmit for a period of time at the position specified by the secondary subband of 6PRB bandwidths, and then repeats the above process. In addition, since the resource blocks on the primary subband of 1PRB bandwidth are also mapped to the corresponding sequence numbers of the secondary subbands, the Relay UEs 4 to 6 transmit the first message on the primary subband of 1PRB bandwidth and then switch to the corresponding secondary subbands of 1PRB bandwidth for transmission. For example, after the Relay UE 5 transmits the first message on the resource block 5, it continues to periodically transmit for a period of time at the position specified by the subband of 1PRB bandwidth, and then repeats the above process.

In the embodiment of the present application, the subbands obtained by dividing the available bandwidth include multiple primary subbands, and the implementation manner of the embodiment of the present application is increased in consideration of a situation that multiple devices with different working bandwidths need to be supported in the same frequency band in practical application.

Fig. 3 and fig. 5 above illustrate the case where the sub-band obtained by dividing the available bandwidth includes at least one primary sub-band and at least one secondary sub-band, and fig. 9 below illustrates the case where the available bandwidth is divided into a plurality of peer sub-bands.

Referring to fig. 9, another embodiment of a resource allocation method and a terminal communication method in the embodiment of the present application includes:

901. the network side equipment equally divides the available bandwidth into a plurality of peer-to-peer sub-bands;

the network side device equally divides the available broadband into a plurality of peer-to-peer sub-bands, that is, the bandwidths of the peer-to-peer sub-bands are all the same, wherein the available broadband is a frequency band used for the first terminal and the second terminal to communicate.

902. Configuring resource configuration information by the network side equipment;

after the network side device equally divides the available bandwidth into a plurality of peer-to-peer subbands, the network side device configures resource configuration information, wherein the resource configuration information includes information of the plurality of peer-to-peer subbands.

Optionally, the information of the sub-band may further include a sending manner of the first message, and the sending manner of the first message may be multiple, including full-wideband sending, comb sending, and hopping sending, which is not limited herein. The full-width transmission mode is used for indicating the first terminal to use all resources of one or more peer-to-peer subbands in a time interval to transmit, the comb transmission mode is used for indicating the first terminal to use resources of one or more peer-to-peer subbands in the same resource position in a time interval to transmit, and the hopping transmission mode is used for indicating the first terminal to use resources of one or more peer-to-peer subbands in different resource positions in different time intervals to transmit.

In addition, the information of the peer-to-peer subband may further include a relationship between bandwidths supported by the second terminals and corresponding transmission periods of the first message, where the relationship may be used for the second terminals with different supported bandwidths, and the first terminal may use different transmission periods when transmitting the first message, for example, when the bandwidths supported by the second terminals are narrower as in an IoT device, the first terminal may use a longer transmission period for transmission.

It should be noted that, in this embodiment of the present application, the network side device divides the available bandwidth into a plurality of peer-to-peer subbands through step 901 and step 902, and configures resource configuration information, and in practical application, both the division of the available bandwidth and the resource configuration information may be preconfigured, so the specific details herein are not limited.

903. The network side equipment sends resource configuration information through a broadcast channel;

after the network side device configures the resource configuration information, the network side device sends the resource configuration information through a broadcast channel, so that both the first terminal and a second terminal within the coverage of the network side device obtain the resource configuration information, wherein the resource configuration information includes information of one or more peer-to-peer subbands, and the information of the peer-to-peer subbands is used for determining the peer-to-peer subbands.

904. The method comprises the steps that network side equipment receives a resource request sent by a first terminal;

in the embodiment of the present application, step 904 is similar to step 304 shown in fig. 3, and is not described herein again.

905. The network side equipment sends a first signaling to a first terminal;

after sending the resource configuration information through the broadcast channel, the network side device sends a first signaling to the first terminal, where the first signaling is used to configure resources on one or more peer subbands to the first terminal, where the first signaling at least includes a resource location and a transmission frequency, it should be noted that the network side device configures resources on one or more peer subbands to the first terminal through the first signaling, and the configuration mode may be dynamic configuration or fixed configuration mode, which is not limited herein.

906. A first terminal acquires resource configuration information;

the first terminal needs to send the first message by using resources on one or more peer-to-peer subbands, so the first terminal needs to acquire information of the one or more peer-to-peer subbands. It should be noted that there are various ways for the first terminal to obtain the resource configuration information, including obtaining the resource configuration information from preconfigured information or receiving the resource configuration information sent by the network side device through a broadcast channel, and therefore the way for the first terminal to obtain the resource configuration information is not limited here.

907. A first terminal sends a first message through a target resource on one or more peer-to-peer subbands;

after receiving a first signaling sent by a network device, a first terminal configures resources on one or more peer-to-peer subbands to the first terminal. And the first terminal determines the target resource on each peer-to-peer sub-band according to the first signaling and the resource configuration information, and sends a first message on one or more peer-to-peer sub-bands through the target resource on each peer-to-peer sub-band.

Optionally, the resource configuration information obtained by the first terminal may further include a sending manner of the first message, where the first terminal may obtain the first message in multiple manners, for example, the sending manner of the preconfigured first message may be obtained, or the sending manner of the first message is extracted from the information of the peer-to-peer subband by the first terminal, and therefore, a specific obtaining manner is not limited here. When the sending mode of the first message included in the resource configuration information obtained by the first terminal is a full-width band mode, the first terminal sends the first message using all resources of one or more peer-to-peer sub-bands in one time interval, as shown in fig. 10, a scenario in which the first terminal sends the first message in the full-width band mode is shown, where an available bandwidth is divided into 6 peer-to-peer sub-bands, the network side device allocates one time interval to each first terminal, where resource blocks with the same number correspond to the same first terminal, so that the first terminal sends the first message in the entire frequency band in one time interval, that is, the first terminal sends the first message using all resources of one or more peer-to-peer sub-bands in one time interval.

When the sending mode of the first message included in the resource configuration information obtained by the first terminal is a comb sending mode, the first terminal sends the first message using resources of one or more peer subbands at the same resource position in a time interval, as shown in fig. 11, which is a scenario where the first terminal sends the first message in a comb sending mode, where an available frequency band is divided into 6 peer subbands, and the network side device allocates sending resources to the first terminal at different time intervals, where resource blocks with the same number correspond to the same first terminal, and it can be seen that, in a time interval, resource blocks with the same number are located at the same resource position of each peer subband, that is, the first terminal sends the first message using resources of one or more peer subbands at the same resource position in a time interval.

When the transmission mode of the first message included in the resource configuration information obtained by the first terminal is the hopping transmission mode, the first terminal transmits the first message using resources of one or more peer-to-peer subbands at different resource locations in different time intervals, as shown in fig. 12, for a scenario in which the first terminal transmits the first message by a hopping transmission scheme, wherein, the available frequency band is divided into 6 peer-to-peer sub-bands, the network side device can configure or pre-configure a time-frequency hopping rule, so that the first terminal hops and sends the first message on all peer-to-peer sub-bands, in fig. 12, 6 first terminals hop according to a certain hopping rule over 6 peer-to-peer subbands and 6 time intervals, i.e. the time and frequency locations of the matching blocks on one or more peer-to-peer sub-bands corresponding to the same first terminal are different, that is, the first terminal transmits the first message using resources of one or more peer-to-peer subbands at different resource locations in different time intervals. Further, the number of resource blocks occupied by the first terminal for sending the first message in a time interval may be set to 1, as shown in fig. 13, the available frequency band is divided into 3 peer-to-peer subbands, and in a time interval, the time domain and the frequency domain position of the resource block corresponding to the first terminal on each peer-to-peer subband are also different, so that the first terminal sends the first message through the resources of the one or more peer-to-peer subbands at different resource positions in different time intervals.

908. The second terminal acquires resource configuration information;

the second terminal needs to receive the first message sent by the first terminal on the resources of one or more peer-to-peer subbands, so the second terminal needs to obtain information of one or more peer-to-peer subbands. It should be noted that there are various ways for the second terminal to obtain the resource configuration information, including obtaining the resource configuration information from preconfigured information or receiving the resource configuration information sent by the network side device through a broadcast channel, and therefore the way for the first terminal to obtain the resource configuration information is not limited here.

909. And the second terminal receives the first message sent by the first terminal on the target subband according to the resource configuration information.

After the second terminal acquires the resource configuration information, the second terminal selects a target sub-band in the supported bandwidth, and receives a first message sent by the first terminal on the target sub-band according to the information of the target sub-band in the resource configuration information.

In the embodiment of the application, the available resources are equally divided into a plurality of peer-to-peer sub-bands, and a plurality of sending modes are provided, so that the second terminal can receive the first message on any peer-to-peer sub-band, the second terminal with a narrow working frequency band does not need to switch the working frequency band, and the power consumption of the second terminal is reduced.
