Description

Resource allocation method, communication device and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource allocation method, a communications device, and a computer readable storage medium.

Background

With the rapid increase of the uplink service demands of users, higher demands are put on the uplink coverage, rate and time delay of terminal devices in the network.

The transmission directions of network devices in the existing time division duplex (Time Division Duplexing, abbreviated as TDD) system on the same time domain resource are the same. In general, network devices in a TDD system configure transmission directions with time slots as granularity. For example, the downlink transmission direction is configured for the time slot 0 and the time slot 1, and the uplink transmission direction is configured for the time slot 2. The network equipment can only perform downlink communication and cannot perform uplink communication in time slot 0 and time slot 1; the network device can only perform uplink communication and cannot perform downlink communication in the time slot 2. For a UE (User Equipment, UE for short) with uplink traffic demand, this results in that the UE cannot transmit uplink data to the network device in time slot 0 and time slot 1, but must wait until time slot 2 for uplink communication.

Compared with the prior art, the technical scheme of the embodiment of the invention has the following beneficial effects:

for the network device side, the network device adopting the embodiment can configure the transmission direction with the frequency domain resources in one time unit as granularity, that is, a plurality of frequency domain resources can be configured in one time unit, and the transmission directions of different frequency domain resource configurations can be different. Thus, for the network device, both the configured frequency domain resources in the uplink communication direction and the configured frequency domain resources in the downlink communication direction may exist in the same time unit. By indicating the frequency domain resources configured based on the configuration mode to the terminal equipment, the network equipment can simultaneously carry out uplink or downlink transmission with different terminal equipment in different frequency domain resources. This is advantageous in order to meet the communication requirements of different terminal devices. For the terminal equipment with uplink service requirement, the implementation of the embodiment can be used for carrying out the uplink service faster, so that the flexibility of the communication mode of the TDD communication system is greatly improved.

For the terminal equipment side, different terminal equipment can determine the frequency domain resources which can be used respectively according to the resource indication information sent by the network equipment, and the available frequency domain resources and the network equipment are used for communication respectively. Because the frequency domain resource in one time unit is used as granularity to configure the transmission direction, different terminal devices can simultaneously carry out uplink communication or downlink communication on different frequency domain resources and network devices. For the terminal equipment with uplink service requirements, if the time unit at the current moment is configured with the available uplink frequency domain resources, the scheme in the prior art is not required to be followed until the next time unit configured as uplink transmission, but the network equipment can be used for configuring the frequency domain resources for uplink transmission to transmit data in the current time unit, so that the uplink service transmission can be completed more quickly.

Detailed Description

As described in the background, in the prior art, a TDD system predefines or configures a transmission direction with a granularity of time units (e.g., time slots), so that the transmission direction is either uplink or downlink in one time unit. For the terminal device with uplink service requirement, if the transmission direction of the current time unit is downlink, the terminal device cannot perform uplink transmission in the current time unit, but must wait until the next time unit of downlink transmission, which results in an increase of uplink service delay.

For the network device, since the transmission direction is configured with the granularity of the time unit, all resources in the same time unit can only be uniformly configured to be uplink or downlink, which can limit the uplink coverage rate of the terminal device in the network.

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a signaling interaction diagram of a resource allocation method according to an embodiment of the present invention.

The scheme of the embodiment can be applied to a resource allocation scene of a TDD communication system, in the scene, the network equipment divides a frequency domain into at least two frequency domain resources, and the frequency domain resources in the same time domain resource are used as granularity to allocate a transmission direction. Therefore, the network equipment can use different frequency domain resources to carry out uplink and downlink communication with different terminal equipment at the same time, and a plurality of terminal equipment can carry out uplink and downlink transmission at different frequency domain resources and network equipment at the same time.

In a specific implementation, in the resource allocation method provided in the following steps (S) 101 to S102, the actions performed by the terminal device may be performed by a chip with a resource allocation function in the terminal device, or may be performed by a baseband chip in the terminal device. The actions performed by the network device may be performed by a chip with a resource allocation function in the network device or may be performed by a baseband chip in the network device.

Specifically, referring to fig. 1, the resource allocation method according to the present embodiment may include the following steps:

s101, the network equipment sends resource indication information to the terminal equipment. Correspondingly, the terminal equipment receives the resource indication information sent by the network equipment.

S102, in response to receiving the resource indication information, the terminal equipment determines the frequency domain position of the available frequency domain resource in at least two frequency domain resources indicated by the resource indication information. Wherein S102 is an optional step.

Further, the resource indication information may be used to indicate at least two frequency domain resources, which may include a first frequency domain resource and a second frequency domain resource, wherein the first frequency domain resource and the second frequency domain resource on the same time unit support different transmission directions. That is, for the first frequency domain resource and the second frequency domain resource on the same time unit, the network device may configure the transmission directions on the two frequency domain resources to be the same or opposite according to the actual needs. The network device may configure the transmission direction of each frequency domain resource after S101 is executed, or may configure the transmission direction of each frequency domain resource synchronously when each frequency domain resource is configured. For example, the transmission direction of the first frequency domain resource support configuration includes uplink, and the transmission direction of the second frequency domain resource support configuration includes downlink. For another example, the transmission direction of the first frequency domain resource support configuration includes a downlink, and the transmission direction of the second frequency domain resource support configuration includes an uplink. Taking the first frequency domain resource as an example, it should be noted that, in some embodiments, the transmission direction of the first frequency domain resource supporting configuration may include uplink and downlink, and the specific configuration of the transmission direction is uplink or downlink, which may be indicated by the network device. Of course, in the embodiment of the present application, the transmission direction of the first frequency domain resource supporting configuration may be only one, such as uplink or downlink, which is not limited.

In the embodiment of the application, the time unit can be the communication granularity of the terminal equipment and the network equipment in the time domain. For example, the time units may be slots, mini-slots, subframes, symbols, frames, etc. The same time unit refers to the same time unit, e.g., two frequency domain resources on the same time slot 0.

In the embodiment of the present application, the frequency domain resource can be understood as: a new introduced granularity of communication between a network device and a terminal device in the frequency domain.

In some embodiments, the frequency domain resource may be a subband (subband). In this embodiment, the sub-band may be understood as: a portion of the sub-band is divided from a segment of the bandwidth. The bandwidth may be a system bandwidth. Alternatively, the bandwidth may be a carrier bandwidth part (BWP). Alternatively, the bandwidth may be a carrier.

Taking BWP as an example of bandwidth, one BWP may be divided into a plurality of sub-bands.

Taking the system bandwidth as an example, the system bandwidth can be divided into a sub-band 0, a sub-band 1, a sub-band 2 and a sub-band 3, the resource indication information indicates the sub-band 0 and the sub-band 1, and the transmission directions of the supporting configuration of the sub-band 0 and the sub-band 1 are different. Alternatively, the resource indication information may also indicate sub-band 0, sub-band 1 and sub-band 3. Alternatively, the resource indication information may also indicate subband 0, subband 1, subband 2, and subband 3.

In the case that the bandwidth is BWP, at least two frequency domain resources indicated by the resource indication information may belong to different BWP or may belong to the same BWP, which is not limited. For example, BWP0 and BWP1 are exemplified, BWP0 is divided into sub-band 00, sub-band 01 and sub-band 02, and BWP1 is divided into sub-band 10, sub-band 11 and sub-band 12. The resource indication information may indicate subband 00 and subband 10, or may indicate subband 00, subband 01, etc.

Of course, in the case that the bandwidth is a carrier, at least two frequency domain resources indicated by the resource indication information may belong to the same carrier or may belong to different carriers, which is not limited.

In some embodiments, the frequency domain resource may be a contiguous set of resource blocks (Resource Block set, RB set for short).

The available frequency domain resources may be frequency domain resources indicated for use by a particular terminal device among the at least two frequency domain resources. For example, the network device sends the same resource indication information to the terminal device 1 and the terminal device 2, where the resource indication information indicates a first frequency domain resource and a second frequency domain resource, and the first frequency domain resource is an available frequency domain resource of the terminal device 1, and the second frequency domain resource is an available frequency domain resource of the terminal device 2.

In some embodiments, at least two frequency domain resources indicated by the resource indication information may be configured to a plurality of terminal devices. Specifically, the network device may send the same resource indication information to the managed plurality of terminal devices, where at least two frequency domain resources indicated by the resource indication information are a complete set of available frequency domain resources of the plurality of terminal devices. Further, the network device may indicate or activate, to each terminal device, a frequency domain resource (i.e. an available frequency domain resource) that the terminal device is actually able to use in the at least two frequency domain resources.

In one possible embodiment, the resource indication information may carry an identity ID of each terminal device, such as a subscriber identity module (Subscriber Identity Module) card number associated with the terminal device. Different IDs associate different ones of the at least two frequency domain resources. Correspondingly, in S102, each terminal device determines, according to its own ID, a location of the available frequency domain resource indicated by the resource indication information to itself.

In some embodiments, at least two frequency domain resources indicated by the resource indication information may be configured exclusively to one terminal device. That is, the network device configures corresponding resource indication information for different terminal devices, respectively. Correspondingly, in S102, the terminal device determines at least two frequency domain resources indicated by the resource indication information as available frequency domain resources, and determines frequency domain positions of the available frequency domain resources.

In one implementation, the resource indication information may be determined or generated by the network device. For example, when the terminal device initially accesses a cell managed by the network device, or when the terminal device enters a connection state from an idle state or an inactive state, the network device may generate resource indication information and perform S101 to transmit to the terminal device.

In one implementation, the resource indication information may be carried by radio resource control (Radio Resource Control, RRC for short) signaling. It should be noted that, the network device may also carry the resource indication information in other signaling or message carrying and send the resource indication information to the terminal device, which is not limited.

In one implementation, the resource indication information may include: the resource allocation device comprises resource position indication information and resource length indication information, wherein the resource position indication information is used for indicating the starting positions of at least two frequency domain resources, and the resource length indication information is used for indicating the resource lengths of the at least two frequency domain resources.

In one example, the resource location indication information may indicate a start location of each of the at least two frequency domain resources, and the resource length indication information may indicate a frequency domain length of each of the frequency domain resources. Accordingly, in S102, the terminal device may determine a resource location of the available frequency domain resource on the frequency domain according to the starting location of the available frequency domain resource and the resource length.

In another example, the resource length of each frequency domain resource may be the same, and the resource length indication information may only need to indicate one resource length. Correspondingly, the terminal device can determine the resource position of each frequency domain resource on the frequency domain according to the starting position of each frequency domain resource and the uniform resource length.

In another example, the at least two frequency domain resources may include a first frequency domain resource, a second frequency domain resource, and a third frequency domain resource, the first frequency domain resource and the second frequency domain resource having the same resource length, the first frequency domain resource and the third frequency domain resource having different resource lengths. The resource location indication information may indicate three start locations and the resource length indication information may indicate two resource lengths. For example, the resource indication information includes three start position information, the resource length indication information may include two resource length information, and the resource indication information may further include an index of each frequency domain resource, the index being associated with the start position information and the resource length information. Correspondingly, the terminal equipment can determine the resource position of the corresponding frequency domain resource on the frequency domain according to the initial position and the resource length associated with the same index. Alternatively, for another example, the resource location indication information includes start location information 1, start location information 2, and start location information 3, and the resource length indication information includes resource length information 1, resource length information 2, and resource length information 3, wherein the resource lengths indicated by the resource length information 1 and the resource length information 2 are the same. And the initial position information and the resource length information are in one-to-one correspondence according to the position sequence in the resource position indication information and the resource length indication information respectively. For example, the start position information may be arranged in the order of the start position of the frequency domain resource from low to high in the resource position indication information, and the resource length information may be arranged in the order of the start position of the frequency domain resource from low to high in the resource length indication information. Alternatively, for another example, the start position information may be arranged in the order of the start position of the frequency domain resource from high to low in the resource position indication information, and the resource length information may be arranged in the order of the start position of the frequency domain resource from high to low in the resource length indication information.

The initial position information 1 corresponds to resource length information 1, the initial position information 1 is used for indicating the initial position of the first frequency domain resource, and the resource length information 1 is used for indicating the resource length of the first frequency domain resource. The starting position information 2 corresponds to resource length information 2, the starting position information 2 is used for indicating the starting position of the second frequency domain resource, and the resource length information 2 is used for indicating the resource length of the second frequency domain resource. The starting position information 3 corresponds to resource length information 3, the starting position information 3 is used for indicating the starting position of the third frequency domain resource, and the resource length information 3 is used for indicating the resource length of the third frequency domain resource.

In one implementation, the entire system bandwidth (system bandwidth) may include at least two frequency domain resources, wherein a starting location of the starting frequency domain resources may be a starting location PointA of the system bandwidth.

In particular, the starting frequency domain resource may be a frequency domain resource having a lowest frequency domain position in the at least two frequency domain resources.

Further, the start position PointA of the system bandwidth is a reference point of the start number of the common resource block (Common Resource Block, abbreviated as CRB) in the system bandwidth, and for each subcarrier interval, the subcarrier interval 0 of the CRB0 is aligned with the start position PointA.

For example, referring to fig. 2, the system bandwidth includes three frequency domain resources, with indexes 0, 1, and 2 (for indicating frequency domain resource 0, frequency domain resource 1, and frequency domain resource 2, respectively). Wherein the frequency domain resource 0 with the lowest frequency domain position is the initial frequency domain resource, and the initial position is the initial position of the system bandwidth (marked by CRB0 in the figure). The starting position of the frequency domain resource 1 is the ending position of the frequency domain resource 0. The starting position of the frequency domain resource 2 is the ending position of the frequency domain resource 1.

In the example shown in fig. 2, the resource indication information may include a frequency domain resource index sequence { index 0, index 1, index 2}, resource location indication information, and resource length indication information. Index 0 is used to indicate frequency domain resource 0, index 1 is used to indicate frequency domain resource 1, and index 2 is used to indicate frequency domain resource 2. The resource location indication information indicates a start location of the frequency domain resource 0, a start location of the frequency domain resource 1, and a start location of the frequency domain resource 2, respectively. The resource length indication information indicates the resource length of the frequency domain resource 0, the resource length of the frequency domain resource 1, and the resource length of the frequency domain resource 2, respectively.

Alternatively, when at least two frequency domain resources are configured continuously in the frequency domain as shown in fig. 2, that is, when the end position of the previous frequency domain resource is the start position of the next frequency domain resource, the resource position indication information may only include the start position of the start frequency domain resource (i.e., frequency domain resource 0), and the terminal device may determine the bandwidth specifically occupied by each frequency domain resource according to the start position of the start frequency domain resource and the resource length of each frequency domain resource.

Alternatively, when at least two frequency domain resources are continuously configured as shown in fig. 2 and the resource lengths are identical, the resource location indication information may include only a start location of a start frequency domain resource (i.e., frequency domain resource 0), and the resource length indication information may include only one resource length. For example, the Resource indication information may include a frequency domain Resource index sequence { index 0, index 1, index 2}, a starting position of the frequency domain Resource 0 is CRB0, and a Resource length (e.g., 3 Resource Blocks (RBs)). The terminal device may determine the bandwidth in the range of crb0 to crb0+3RB as the frequency domain resource 0, the bandwidth in the range of crb0+3RB to crb0+6RB as the frequency domain resource 1, and the bandwidth in the range of crb0+6RB to crb0+9RB as the frequency domain resource 2.

In one implementation, the entire system bandwidth may include at least two frequency domain resources, wherein the starting frequency domain resource may include a first sub-frequency domain resource and a second sub-frequency domain resource. The first sub-frequency domain resource and the second sub-frequency domain resource are discontinuous, and a start position of the sub-frequency domain resource with a lower frequency domain position in the first sub-frequency domain resource and the second sub-frequency domain resource may be a start position PointA of the system bandwidth.

For example, referring to fig. 3, the system bandwidth includes two frequency domain resources, with indexes 0 and 1 (for indicating frequency domain resource 0 and frequency domain resource 1, respectively), wherein frequency domain resource 0 with the lowest frequency domain position is the starting frequency domain resource and includes discontinuous first and second sub-frequency domain resources. The starting position of the first sub-frequency domain resource with the lower frequency domain position in the first sub-frequency domain resource and the second sub-frequency domain resource is the starting position of the system bandwidth (marked by CRB0 in the figure), the starting position of the frequency domain resource 1 is the ending position of the first sub-frequency domain resource, and the starting position of the second sub-frequency domain resource is the ending position of the frequency domain resource 1.

In the example shown in fig. 3, the resource indication information may include a frequency domain resource index sequence { index 0, index 1}, resource location indication information, and resource length indication information. Index 0 is used to indicate frequency domain resource 0 and index 1 is used to indicate frequency domain resource 1. The resource location indication information may include a start location s0 of a first sub-frequency domain resource of the frequency domain resource 0, a start location s1 of a second sub-frequency domain resource of the frequency domain resource 0, and a start location s2 of the frequency domain resource 1. The resource length indication information may include a resource length n0 of the first sub-frequency domain resource of the frequency domain resource 0, a resource length n1 of the second sub-frequency domain resource of the frequency domain resource 0, and a resource length n2 of the frequency domain resource 1.

In one implementation, the frequency domain resources of the at least two frequency domain resources other than the starting frequency domain resource may be contiguous resources or discontinuous resources. Similarly, the starting frequency domain resource may also be a contiguous resource. The terminal device may determine whether the frequency domain resource contains a plurality of RBs that are continuous or a plurality of RBs that are discontinuous according to the number of start positions of the frequency domain resource configuration for the same index in the resource location indication information.

In one implementation, the at least two frequency domain resources may occupy the entire system bandwidth, or may occupy only a portion of the entire system bandwidth.

In one implementation, a serving cell of a terminal device may include at least two frequency domain resources, where a starting location of a starting frequency domain resource may be a starting location of a carrier used by the serving cell, such as a starting CRB.

For example, the resource indication information may be carried in a serving cell configuration IE (Searvingcellconfig IE) of RRC signaling, and a frequency domain resource list, a frequency domain resource per subcarrier interval, and a frequency domain resource field may be configured in the IE. The frequency domain resource comprises a frequency domain resource field, at least one starting CRB and at least one CRB number, wherein the frequency domain resource field is used for allocating the subcarrier interval of the frequency domain resource, and the starting position and the resource length of each frequency domain resource are represented. That is, the resource location indication information and the resource length indication information may be carried in a frequency domain resource field. Each starting CRB corresponds to a respective number of CRBs, e.g. the correspondence between the starting CRBs and the number of CRBs may be determined according to the index of the frequency domain resource.

For example, referring to fig. 4, one carrier may include three frequency domain resources with indexes 0, 1, and 2, respectively (for indicating frequency domain resource 0, frequency domain resource 1, and frequency domain resource 2, respectively). Wherein, the frequency domain resource 0 with the lowest frequency domain position is the initial frequency domain resource, and the initial position is the initial position of the carrier. The starting position of the frequency domain resource 1 is the ending position of the frequency domain resource 0. The starting position of the frequency domain resource 2 is the ending position of the frequency domain resource 1. 3 starting CRBs and 3 CRB numbers are configured under the frequency domain resource field.

Alternatively, for the case where at least two frequency domain resources are consecutively configured as shown in fig. 4, 1 starting CRB and 3 CRB numbers may be configured under the frequency domain resource field. The terminal equipment determines the starting position of the frequency domain resource 0 according to the configured starting CRB, and determines the resource length of the frequency domain resource 0 according to the number of CRBs corresponding to the starting CRB. And further determining the ending position of the frequency domain resource 0 as the starting position of the frequency domain resource 1, and determining the resource length of the frequency domain resource 1 according to the CRB number of the frequency domain resource 1. And finally, determining the ending position of the frequency domain resource 1 as the starting position of the frequency domain resource 2, and determining the resource length of the frequency domain resource 2 according to the CRB number of the frequency domain resource 2, thereby determining the bandwidth which is specifically occupied by each of the three frequency domain resources.

Alternatively still, the starting position of the starting frequency domain resource may be predefined by the network device and the terminal device as the starting position of the carrier. This is advantageous in saving signaling overhead.

Or, when the resource lengths of the at least two frequency domain resources are the same, 3 starting CRBs and 1 number of CRBs may be configured in the frequency domain resource field.

In one implementation, the entire carrier may include at least two frequency domain resources, wherein the starting frequency domain resource may include a first sub-frequency domain resource and a second sub-frequency domain resource. The first sub-frequency domain resource and the second sub-frequency domain resource are discontinuous, and a starting position of the sub-frequency domain resource with a lower frequency domain position in the first sub-frequency domain resource and the second sub-frequency domain resource may be a starting position of the carrier.

For example, referring to fig. 5, a carrier includes two frequency domain resources with indexes of 0 and 1 (for indicating frequency domain resource 0 and frequency domain resource 1, respectively), wherein frequency domain resource 0 with the lowest frequency domain position is a starting frequency domain resource and includes discontinuous first, second and third sub-frequency domain resources, and frequency domain resource 1 includes discontinuous fourth and fifth sub-frequency domain resources. The starting position of the first sub-frequency domain resource with the lowest frequency position in the first sub-frequency domain resource, the second sub-frequency domain resource and the third sub-frequency domain resource is the starting position of the carrier. The frequency domain resource field is configured with 5 starting CRBs and 5 CRB numbers, wherein the frequency domain resource 0 is configured with 3 starting CRBs (denoted as s0, s1, and s2, respectively) and 3 CRB numbers (denoted as n0, n1, and n2, respectively), and the frequency domain resource 1 is configured with 2 starting CRBs (denoted as s3 and s 4) and 2 CRB numbers (denoted as n3 and n 4). The terminal device may determine the frequency domain position of the first sub-frequency domain resource according to s0 and n0, determine the frequency domain position of the second sub-frequency domain resource according to s1 and n1, determine the frequency domain position of the third sub-frequency domain resource according to s2 and n2, determine the frequency domain position of the fourth sub-frequency domain resource according to s3 and n3, and determine the frequency domain position of the fifth sub-frequency domain resource according to s4 and n 4.

Alternatively, when the resource lengths of the first sub-frequency domain resource and the second sub-frequency domain resource are the same, 2 starting CRBs and 1 number of CRBs may be configured for frequency domain resource 0 in the frequency domain resource field.

In one implementation, the at least two frequency domain resources may occupy the entire carrier, or may occupy only a portion of the bandwidth of the entire carrier.

In one implementation, the starting position of the starting frequency domain resource of the at least two frequency domain resources may be a starting position of a BWP of the terminal device, such as a starting physical resource block (Physical Resource Block, abbreviated PRB) of the BWP.

For example, the resource indication information may be carried in a BWP IE, in which a frequency domain resource list, a frequency domain resource per subcarrier spacing, and a frequency domain resource field may be configured.

For example, referring to fig. 6, one BWP may include three frequency domain resources, with indexes of 0, 1 and 2, respectively (for indicating frequency domain resource 0, frequency domain resource 1 and frequency domain resource 2, respectively), wherein frequency domain resource 0 with the lowest frequency domain position is a starting frequency domain resource, and its starting position is a starting PRB of the BWP (denoted as PRB 0). There is a non-zero interval between the starting position of frequency domain resource 1 and the ending position of frequency domain resource 0, and likewise there is a non-zero interval between the starting position of frequency domain resource 2 and the ending position of frequency domain resource 1. The 3 starting PRBs and 3 PRB numbers are configured under the frequency domain resource field. By controlling the specific location and number of starting PRBs for the same frequency domain resource, the network device may configure adjacent frequency domain resources to be discontinuous, as shown in fig. 7.

In one implementation, the entire BWP may include at least two frequency domain resources, wherein the starting frequency domain resource may include a first sub-frequency domain resource and a second sub-frequency domain resource. The first sub-frequency domain resource and the second sub-frequency domain resource are discontinuous, and a starting position of the sub-frequency domain resource with a lower frequency domain position in the first sub-frequency domain resource and the second sub-frequency domain resource may be a starting PRB of the BWP.

For example, referring to fig. 7, the bwp includes three frequency domain resources, indexes 0, 1 and 2 (for indicating frequency domain resource 0, frequency domain resource 1 and frequency domain resource 2, respectively), wherein frequency domain resource 0 having the lowest frequency domain position is a start frequency domain resource and includes discontinuous first and second sub-frequency domain resources, frequency domain resource 1 is located between the first and second sub-frequency domain resources, and a start position of frequency domain resource 2 and an end position of the second sub-frequency domain resource have a non-zero interval therebetween. The frequency domain resource field may be configured with 4 starting PRBs and 4 PRB numbers, where frequency domain resource 0 is configured with 2 starting PRBs (denoted as s0 and s1, respectively) and 2 PRB numbers (denoted as n0 and n1, respectively), frequency domain resource 1 is configured with 1 starting PRB (denoted as s 2) and 1 PRB number (denoted as n 2), and frequency domain resource 2 is configured with 1 starting PRB (denoted as s 3) and 1 PRB number (denoted as n 3). The terminal device may determine the frequency domain position of the first sub-frequency domain resource according to s0 and n0, determine the frequency domain position of the second sub-frequency domain resource according to s1 and n1, determine the frequency domain position of the frequency domain resource 1 according to s2 and n2, and determine the frequency domain position of the frequency domain resource 2 according to s3 and n 3. By controlling the specific location and number of starting PRBs of the second sub-frequency domain resource and the specific location of starting PRBs of the frequency domain resource 2, the network device may configure the second sub-frequency domain resource and the frequency domain resource 2 to be discontinuous, as shown in fig. 7.

In one implementation, the resource indication information may indicate a total number of at least two frequency domain resources and a resource length of each frequency domain resource, wherein the resource length of each frequency domain resource may be associated with a bandwidth of the BWP. For example, a frequency domain resource allocation table storing an association relationship of at least one set of bandwidths and resource lengths of frequency domain resources may be predefined.

Specifically, a resource length field and a frequency domain resource number field may be introduced in the BWP IE, respectively representing the resource length of each frequency domain resource and the total number of at least two frequency domain resources configured.

In one example, the frequency domain resource configuration table may report the configuration table for the sub-bands along with channel state information (Channel State Information, CSI) of the existing protocol, and in general, the larger the BWP bandwidth, the larger the resource length of each frequency domain resource.

In one implementation, the terminal device may be configured with a plurality of BWP, and the network device may configure at least two frequency domain resources for each BWP of the plurality of BWP, respectively, and indicate to the terminal device through the resource indication information. For example, the RRC signaling may include a plurality of resource indication information, wherein each resource indication information is used to indicate at least two frequency domain resources on the corresponding BWP. For another example, one resource indication information for indicating at least two frequency domain resources on each of the plurality of BWP may be included in the RRC signaling.

In one embodiment, if the transmission direction of the first frequency domain resource is different from the transmission direction of the second frequency domain resource in the same time unit, a guard band (guard band) may be spaced between the first frequency domain resource and the second frequency domain resource. The guard bandwidth may be used to avoid interference between uplink and downlink transmissions, such as to avoid interference from downlink transmissions to uplink reception. In other words, the guard bandwidth may be a frequency domain resource that is not used for both uplink and downlink communications, and by dividing a blank bandwidth between adjacent frequency domain resources with different transmission directions, mutual interference between communications in different directions performed on the adjacent frequency domain resources is avoided.

In one example, the protection bandwidth may be predefined. When the network device needs to send downlink data on a certain frequency domain resource and receive uplink data on an adjacent frequency domain resource in one time unit, that is, the transmission directions of the adjacent frequency domain resources (such as the first frequency domain resource and the second frequency domain resource) are different, the network device may further divide a part of bandwidth in the first frequency domain resource or the second frequency domain resource as a protection bandwidth. As regards the division in particular in the first frequency domain resource or in the second frequency domain resource, this may be based on predefined settings or may be determined by the network device through a pre-negotiation with the terminal device, which is not limited in this example.

For example, with continued reference to fig. 3, it is assumed that the transmission direction of the frequency domain resource 0 configured by the network device to the terminal device is downstream, and the transmission direction of the frequency domain resource 1 is upstream. The network device may divide a portion of the bandwidth from the first sub-frequency domain resource of frequency domain resource 0 and the vicinity of frequency domain resource 1 as the guard bandwidth and divide a portion of the bandwidth from the vicinity of frequency domain resource 1 and the second sub-frequency domain resource of frequency domain resource 0 as the guard bandwidth.

For another example, when the network device configures the frequency domain position of each frequency domain resource, it can be ensured that the end position of the previous frequency domain resource and the start position of the next frequency domain resource do not coincide, and the reserved blank resource is the protection bandwidth. For example, the blank resource between the second sub-frequency domain resource of the frequency domain resource 0 and the frequency domain resource 2 in fig. 7 may be used as the guard bandwidth. Further, the transmission direction of the frequency domain resource 0 may be configured as uplink, and the transmission direction of the frequency domain resource 2 may be configured as downlink. Alternatively, the transmission direction of the frequency domain resource 0 and the transmission direction of the frequency domain resource 2 may be configured to be the same direction. That is, the network device may reserve a blank resource between adjacent frequency domain resources with opposite transmission directions to form a guard bandwidth, or may reserve a blank resource between every two adjacent frequency domain resources without considering the transmission directions to form a guard bandwidth. The latter implementation facilitates a flexible subsequent configuration of the transmission direction.

In another example, the protection bandwidth may be indicated to the terminal device for the network device. For example, the resource indication information may further include a guard band list (guard band list) including an index of guard bands, the resource location indication information may further include a start location of each guard band, and the resource length indication information may further indicate a resource length of each guard band. Correspondingly, when the terminal device executes S102, the frequency domain position of each frequency domain resource may be determined according to the starting position and the resource length of each frequency domain resource, and the frequency domain position of each protection bandwidth may be determined according to the starting position and the resource length of each protection bandwidth.

The network device may configure the guard bandwidth according to the transmission direction of each frequency domain resource, e.g., only configure the guard bandwidth between the first frequency domain resource and the second frequency domain resource when the transmission directions of the two are opposite. If the transmission directions of the first frequency domain resource and the second frequency domain resource are the same, the network device may not configure a protection bandwidth between the first frequency domain resource and the second frequency domain resource, which is beneficial to improving the utilization rate of the frequency domain resources.

Thus, for the network device side, the network device adopting the embodiment can configure the transmission direction with the frequency domain resources in one time unit as granularity, that is, multiple frequency domain resources can be configured in one time unit, and the transmission directions of different frequency domain resource configurations can be different. Thus, for the network device, both the configured frequency domain resources in the uplink communication direction and the configured frequency domain resources in the downlink communication direction may exist in the same time unit. By indicating the frequency domain resources configured based on the configuration mode to the terminal equipment, the network equipment can simultaneously carry out uplink or downlink transmission with different terminal equipment in different frequency domain resources. This is advantageous in order to meet the communication requirements of different terminal devices. For the terminal equipment with uplink service requirement, the implementation of the embodiment can be used for carrying out the uplink service faster, so that the flexibility of the communication mode of the TDD communication system is greatly improved.

For the terminal equipment side, different terminal equipment can determine the frequency domain resources which can be used respectively according to the resource indication information sent by the network equipment, and the available frequency domain resources and the network equipment are used for communication respectively. Because the frequency domain resource in one time unit is used as granularity to configure the transmission direction, different terminal devices can simultaneously carry out uplink communication or downlink communication on different frequency domain resources and network devices. For the terminal equipment with uplink service requirements, if the time unit at the current moment is configured with the uplink available frequency domain resources, the network equipment can be used for configuring the frequency domain resources for uplink transmission to the terminal equipment in the current time unit to transmit data, so that the uplink service transmission can be completed more quickly.
