in step S2201, the network device sends each first resource group to the terminal device in turn.

In some embodiments, a terminal device may receive a first set of resources. For example, the terminal device may receive a first resource group sent by the network device. For another example, the terminal device may also receive the first resource group sent by the other entity.

In some embodiments, the transmission interval between adjacent first resource groups is a first time slot.

In some embodiments, the first set of resources may belong to a first set of resources, which may be non-periodic sets of resources.

In some embodiments, the first set of resources may include M1 first resource groups, which may include N1 second reference signal resources, where M1 is an integer greater than 1 and N1 is an integer greater than 1.

In some embodiments, the name of the first resource group is not limited, and may be, for example, "resource group", "resource combination", or the like.

In some embodiments, the second information of the third reference signal resource may be the same, wherein the third reference signal resource may include a second reference signal resource having the same first index value in the M1 first resource groups.

In some embodiments, the second information may include at least one of: third information, fourth information, the third information may include at least one of: bandwidth, subcarrier location, starting location of resource block, the fourth information is symbol location in different time slots.

In some embodiments, the first index value may be an index value of the second reference signal resource obtained by sorting N1 second reference signal resources in the first resource group according to a resource index.

In some embodiments, the ports corresponding to the third reference signal resource of the same port index are the same.

In some embodiments, the port index may be understood as an index value corresponding to the port, taking the third reference signal resource as a CSI-RS resource as an example, where the index value may be an index value of the CSI-RS port.

For example, the network device may configure the terminal device with a first resource set, which may be one CSI-RS resource set, including 8 CSI-RS resources, where the resource IDs of the 8 CSI-RS resources are 0 to 7. For convenience of description, the 8 CSI-RS resources may be referred to as CSI-RS resource 0, CSI-RS resource 1, CSI-RS resource 2, CSI-RS resource 3, CSI-RS resource 4, CSI-RS resource 5, CSI-RS resource 6, CSI-RS resource 7. The network device may divide the 8 CSI-RS resources into 4 first resource groups: resource group a, resource group B, resource group C, and resource group D, each first resource group includes 2 second reference signal resources, i.e., 2 CSI-RS resources. Wherein, resource group A may include CSI-RS resource 0 and CSI-RS resource 1, resource group B may include CSI-RS resource 2 and CSI-RS resource 3, resource group C may include CSI-RS resource 4 and CSI-RS resource 5, and resource group D may include CSI-RS resource 6 and CSI-RS resource 7. For each first resource group, 2 CSI-RS resources in the first resource group may be ordered according to a resource index of the CSI-RS resources in the first resource group, and an index value of each CSI-RS resource after the ordering may be used as the first index value. Taking the resource group A as an example, after sorting, the CSI-RS resource 0 is in front of the CSI-RS resource 1, and then the first index value of the CSI-RS resource 0 is 0, and the first index value of the CSI-RS resource 1 is 1. Taking the resource group B as an example, after the CSI-RS resource 2 is ordered, the first index value of the CSI-RS resource 2 is 0, and the first index value of the CSI-RS resource 3 is 1. According to the above-mentioned sequencing of the resource group C and the resource group D, the first index value of the CSI-RS resource 4 in the resource group C is 0, the first index value of the CSI-RS resource 5 is 1, the first index value of the CSI-RS resource 6 in the resource group D is 0, and the first index value of the CSI-RS resource 7 is 1.

It should be noted that, the number of CSI-RS resources included in the first resource set is illustrated, and the ordering manner and the ordering result of the CSI-RS resources in each first resource set are not limited in this embodiment of the present disclosure.

Continuing with the description of the first resource set, the first index values of the CSI-RS resource 0, the CSI-RS resource 2, the CSI-RS resource 4, and the CSI-RS resource 6 are all 0, and the CSI-RS resource 0, the CSI-RS resource 2, the CSI-RS resource 4, and the CSI-RS resource 6 may be used as a third reference signal resource, for example, may be named as a third reference signal resource a, the first index values of the CSI-RS resource 1, the CSI-RS resource 3, the CSI-RS resource 5, and the CSI-RS resource 7 are all 1, and the CSI-RS resource 1, the CSI-RS resource 3, the CSI-RS resource 5, and the CSI-RS resource 7 may be used as a third reference signal resource, for example, may be named as a third reference signal resource B. The second information of the third reference signal resource a is the same and the second information of the third reference signal resource B is the same.

In some embodiments, the second information of the third reference signal resource a is the same, which is understood as that the third information of the third reference signal resource a is the same, or the fourth information of the third reference signal resource a is the same, or the third information and the fourth information of the third reference signal resource a are the same.

Taking the third reference signal resource a as an example in the first resource set, the first index values of the 4 CSI-RS resources included in the third reference signal resource a are all 0, and if the port indexes of the CSI-RS resource 0 and the CSI-RS resource 1 are the same, the ports corresponding to the CSI-RS resource 0 and the CSI-RS resource 1 are the same.

It should be noted that, the bandwidth may be interpreted as a bandwidth of the CSI-RS resource, the subcarrier position may be interpreted as a subcarrier position of the CSI-RS resource, and the start position of the resource block may be interpreted as a start position of the resource block of the CSI-RS resource. Symbol positions within different slots may be interpreted as symbol positions of CSI-RS resources within different slots.

In some embodiments, the transmission interval between adjacent fourth reference signal resources is a first slot, the fourth reference signal resources including a first second reference signal resource in each first resource group.

In some embodiments, the first time slot may be agreed by a protocol, or may be predefined on the network side, for example, the first time slot may be m time slots.

In some embodiments, a "first second reference signal resource" may be understood as a second reference signal resource with the smallest first index value in each first resource group. Taking the first resource set as an example, the fourth reference signal resource may include CSI-RS resource 0 in resource group a, CSI-RS resource 2 in resource group B, CSI-RS resource 4 in resource group C, and CSI-RS resource 6 in resource group D, where a transmission interval between CSI-RS resource 0 and CSI-RS resource 2 is a first time slot, a transmission interval between CSI-RS resource 2 and CSI-RS resource 4 is a first time slot, and a transmission interval between CSI-RS resource 4 and CSI-RS resource 6 is a first time slot.

In some embodiments, the time slot in which the second reference signal resource except the first second reference signal resource is located in each first resource group may be determined according to the location in which the first second reference signal resource is located in the first resource group. For example, the location of CSI-RS resource 1 in resource group a may be determined according to the time slot in which CSI-RS resource 0 is located.

In some embodiments, the second location of the fifth reference signal resource in each first resource group is the same, or the second locations of the ports corresponding to the fifth reference signal resource in each first resource group are continuous, where the fifth reference signal resource includes all or part of the second reference signal resources in the first resource group, and the second locations include at least one of the following: OFDM symbol position, subcarrier position.

Continuing taking the resource group a of the first resource set as an example, two CSI-RS resources in the resource group a have the same OFDM symbol position and/or subcarrier position, or subcarrier positions or OFDM symbol positions where ports corresponding to the two CSI-RS resources in the resource group a are located are continuous.

In some embodiments, the network device sending the first resource group to the terminal device may be understood as the network device sending a plurality of second reference signal resources in the first resource group to the terminal device.

In some embodiments, the network device may transmit the plurality of second reference signal resources in the first resource group in one or more time slots, and after the first time slot is spaced, the network device may transmit the plurality of second reference signal resources in the second first resource group. And so on until the transmission of the plurality of second reference signal resources within each first resource group is completed.

In some embodiments, a plurality of first resource groups may be ordered, and a group index value for each first resource group is determined. For example, the group index value of resource group A is 0, the group index value of resource group B is 1, the index value of resource group C is 2, and the group index value of resource group D is 3.

In some embodiments, the first resource group may be understood as the first resource group with the smallest group index value, and the last first resource group may be understood as the first resource group with the largest group index value.

For example, the network device may first transmit two CSI-RS resources in the resource group a, after a first time slot is separated, then transmit two CSI-RS resources in the resource group B, after the first time slot is separated, then transmit two CSI-RS resources in the resource group C, after the first time slot is separated, and finally transmit two CSI-RS resources in the resource group D.

In some embodiments, the transmission location of the first second reference signal resource in each first resource group may be determined according to an aperiodic offset configured by the network device through radio resource control (Radio Resource Control, RRC).

By adopting the method, the network equipment can transmit a plurality of second reference signal resources in the first resource group at a time, and the time domain positions or the frequency domain positions of the plurality of second reference signal resources are configured to support more transmitting antenna ports, so that the system performance is improved.

Fig. 2C is an interactive schematic diagram illustrating a resource allocation method according to an embodiment of the disclosure. The method may be performed by the communication system described above. As shown in fig. 2C, the method may include:

In step S2301, the network device sequentially sends the seventh reference signal resource to the terminal device according to the second index value of the seventh reference signal resource.

In some embodiments, the terminal device may receive a seventh reference signal resource. For example, the terminal device may receive a seventh reference signal resource transmitted by the network device. For another example, the terminal device may also receive the seventh reference signal resource sent by the other entity.

In some embodiments, the transmission interval between seventh reference signal resources of different second index values is the second slot.

In some embodiments, the second time slot may be agreed by a protocol, or may be predefined on the network side, for example, the second time slot may be n time slots.

In some embodiments, the second time slot may be the same as the first time slot or different from the first time slot, which is not limited by the embodiments of the present disclosure.

In some embodiments, the seventh reference signal resource may belong to a first set of resources, which may be a non-periodic set of resources.

In some embodiments, the first set of resources may include N2 second resource groups including M2 sixth reference signal resources, where M2 is an integer greater than 1 and N2 is an integer greater than 1.

For example, the network device may configure the terminal device with a first resource set, which may be one CSI-RS resource set, including 8 CSI-RS resources, where the resource IDs of the 8 CSI-RS resources are 0 to 7. For convenience of description, the 8 CSI-RS resources may be referred to as CSI-RS resource 0, CSI-RS resource 1, CSI-RS resource 2, CSI-RS resource 3, CSI-RS resource 4, CSI-RS resource 5, CSI-RS resource 6, CSI-RS resource 7. The network device may divide the 8 CSI-RS resources into 2 second resource groups: resource group E, resource group F, each second resource group comprises 4 sixth reference signal resources, i.e. 4 CSI-RS resources. The resource group E may include CSI-RS resource 0, CSI-RS resource 1, CSI-RS resource 2, and CSI-RS resource 3, and the resource group F may include CSI-RS resource 4, CSI-RS resource 5, CSI-RS resource 6, and CSI-RS resource 7.

In some embodiments, the transmission interval between adjacent sixth reference signal resources in the second resource group is a second slot.

Taking the above resource group E as an example, the transmission interval between the CSI-RS resource 0 and the CSI-RS resource 1 is the second time slot, the transmission interval between the CSI-RS resource 1 and the CSI-RS resource 2 is the second time slot, and the transmission interval between the CSI-RS resource 2 and the CSI-RS resource 3 is the second time slot.

In some embodiments, fifth information of the M2 sixth reference signal resources in each second resource group is the same, the fifth information including at least one of: sixth information, seventh information, the sixth information including at least one of: the seventh information is symbol positions in different time slots, and the ports corresponding to the sixth reference signal resources with the same port index in the M2 sixth reference signal resources are the same.

Taking the above resource group E as an example, the fifth information of CSI-RS resource 0, CSI-RS resource 1, CSI-RS resource 2, and CSI-RS resource 3 in the resource group E are the same. If the port indexes of the CSI-RS resource 0 and the CSI-RS resource 1 are the same, the ports corresponding to the CSI-RS resource 0 and the CSI-RS resource 1 are the same.

In some embodiments, a seventh reference signal resource is the same at a third position in the same or different time slot, or a third position where a port corresponding to the seventh reference signal resource is located is continuous, where the seventh reference signal resource includes a sixth reference signal resource with the same second index value in N2 second resource groups, and the third position includes at least one of the following: the second index value is an index value of the sixth reference signal resource obtained by sequencing the M2 sixth reference signal resources in the second resource group according to the resource index.

Continuing taking the above CSI-RS resource set as an example, for each second resource group, 4 CSI-RS resources in the second resource group may be ordered according to the resource index of the CSI-RS resource in the second resource group, and after the ordering, the index value of each CSI-RS resource may be used as the second index value. For the resource group E, the ordered CSI-RS resources are in the order of CSI-RS resource 0, CSI-RS resource 1, CSI-RS resource 2 and CSI-RS resource 3, and the CSI-RS resource 0 is at the forefront, wherein the second index value of the CSI-RS resource 0 is 0, and the second index value of the CSI-RS resource 3 is 3. For the resource group F, the ordered CSI-RS resources are CSI-RS resources 4, CSI-RS resources 5, CSI-RS resources 6 and CSI-RS resources 7 in sequence, the ordered CSI-RS resources 4 are at the forefront, the second index value of the CSI-RS resources 4 is 0, and the second index value of the CSI-RS resources 7 is 3.

It should be noted that, the above-mentioned ordering manner and ordering result of CSI-RS resources in each second resource group are illustrative, and the embodiments of the present disclosure are not limited thereto.

The fifth information of the seventh reference signal resource a is the same, the fifth information of the seventh reference signal resource B is the same, the fifth information of the seventh reference signal resource C is the same, and the fifth information of the seventh reference signal resource D is the same.

In some embodiments, the third time slot may be agreed by a protocol, or may be predefined on the network side, for example, the third time slot may be k time slots.

In some embodiments, the third time slot may be the same as the first time slot or different from the first time slot, which is not limited by the embodiments of the present disclosure.

In some embodiments, the ninth reference signal resource may comprise an eighth reference signal resource having the same third index value.

The resource allocation method of the present disclosure is described below by three specific embodiments.

Example 1,

The gNB configures a CSI-RS resource set for the UE, wherein the CSI-RS resource set comprises K _s =4 CSI-RS resource groups, and each CSI-RS resource group comprises K=2 CSI-RS resources. And the gNB sequentially transmits the four CSI-RS resource groups according to the index sequence of the CSI-RS resource groups. Fig. 6A is a schematic diagram illustrating a resource transfer in accordance with an embodiment of the present disclosure. As shown in fig. 6A, the gNB first transmits each CSI-RS resource (abbreviated as CSI-RS in the figure) in the first Group (Group 0) and finally transmits each CSI-RS resource in the fourth Group (Group 3) in order of the indexes from small to large. The interval of adjacent CSI-RS resource groups is m time slots. If the CSI-RS resources of the CSI-RS resource group are transmitted on two adjacent slots, the interval of the adjacent CSI-RS resource group refers to the interval between the first CSI-RS resources transmitted in the CSI-RS resource group.

And sequencing each CSI-RS resource group according to the sequence from the small resource ID to the large resource ID. When the CSI-RS are configured, the i < th > e {0,1} CSI-RS resources of each CSI-RS resource group have the same bandwidth and/or the same subcarrier position, and optionally, in different time slots, the OFDM conforming positions where the i < th > CSI-RS resources of each CSI-RS resource group are located are also the same.

For k=2 CSI-RS resources within each CSI-RS resource group, it is assumed that the two CSI-RS resources are configured within one slot, the OFDM symbol positions of the two CSI-RS resources are the same and/or the subcarrier positions are also the same. Optionally, subcarriers where ports of k=2 CSI-RS resources are located are consecutive or OFDM symbol positions where ports are located are consecutive.

And when transmitting each CSI-RS resource to the UE, the gNB is arranged in the adjacent CSI-RS resource group, wherein the interval between the 1 st CSI-RS resource in the adjacent CSI-RS resource group is m time slots. The 2 nd and 1 st CSI-RS resources of each CSI-RS resource group are in the same time slot. The transmission position of the 1 st CSI-RS resource of the first CSI-RS resource group is determined according to the aperiodic offset of gNB through RRC configuration. The gNB firstly transmits each CSI-RS resource in the first CSI-RS resource group, and then sequentially transmits each CSI-RS resource in the K _s CSI-RS resource groups according to the index of the CSI-RS resource group.

If the resources of the CSI-RS resource set are divided into k=2 CSI-RS resource groups, each CSI-RS resource group contains K _s =4 CSI-RS resources. Fig. 6B is a schematic diagram illustrating a resource transfer in accordance with an embodiment of the present disclosure. As shown in fig. 6B, the CSI-RS resource with id=0 in the first Group (Group 0) and the CSI-RS resource with id=1 in the second Group (Group 1) may be transmitted first, then the CSI-RS resource with id=2 in the first Group (Group 0) (abbreviated as CSI-RS in the figure) and the CSI-RS resource with id=3 in the second Group (Group 1) may be transmitted, and so on, and finally the CSI-RS resource with id=6 in the first Group (Group 0) and the CSI-RS resource with id=7 in the second Group (Group 1) may be transmitted.

EXAMPLE 2,

The gNB configures the UE with K _s = 4 aperiodic CSI-RS resource sets, each CSI-RS resource set containing K = 4 CSI-RS resources. The index or resource set ID of the CSI-RS resource set is ordered, and the index or ID of each CSI-RS resource within the CSI-RS resource set is also ordered. According to the corresponding sequencing, the ith CSI-RS resource in each CSI-RS resource set configured by the gNB has the same bandwidth and/or subcarrier position, or the same symbol position in different time slots, and the OFDM symbol position and/or subcarrier position of K=4 CSI-RS resources formed by the (0, 1,2, 3) th CSI-RS resources in each CSI-RS resource set are the same, or the subcarriers where ports of the K CSI-RS resources are located are continuous or the OFDM symbol positions where the ports of the K CSI-RS resources are located are continuous.

When each CSI-RS resource of each CSI-RS resource set is transmitted, the transmission interval of the ith CSI-RS resource in the adjacent CSI-RS resource set is m time slots. K=4 CSI-RS resources may be transmitted on t=2 slots. The gNB firstly transmits the 1 st CSI-RS resource in all Ks CSI-RS resource sets, then transmits the 2 nd CSI-RS resource in all Ks CSI-RS resource sets after m time slots are separated, and so on until the 4 th CSI-RS resource in all Ks CSI-RS resource sets is transmitted.

EXAMPLE 3,

The gNB configures the UE with k=4 aperiodic CSI-RS resource sets, each CSI-RS resource set containing ks=4 CSI-RS resources. The index or resource set ID of the CSI-RS resource set is ordered, and the index or ID of each CSI-RS resource within the CSI-RS resource set is also ordered. According to the corresponding ordering, all the CSI-RS resources in each CSI-RS resource set configured by gNB have the same bandwidth and/or subcarrier position, or the same symbol position in different time slots, and the OFDM symbol position and/or subcarrier position of K=4 CSI-RS resources formed by the (E {0,1,2, 3) th CSI-RS resource in each CSI-RS resource set are the same, or the subcarrier position where the K CSI-RS resources formed by the (E) th CSI-RS resource in each CSI-RS resource set are continuous or the OFDM symbol position where the K CSI-RS resources are continuous.

When transmitting each CSI-RS resource of each CSI-RS resource set, the transmission interval of adjacent CSI-RS resources in each CSI-RS resource set is m time slots. The gNB firstly transmits the 1 st CSI-RS resource in each CSI-RS resource set, and K=4 CSI-RS resources consisting of the 1 st CSI-RS resource in each CSI-RS resource set are transmitted in one or T=2 time slots. And then transmitting K=4 CSI-RS resources consisting of the 2 nd CSI-RS resources in all K CSI-RS resources after m time slots are separated, and so on until the 4 th CSI-RS resource in all K CSI-RS resources is transmitted.
