Description

Resource allocation method and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource allocation method and a base station.

Background

In 2017, the 3GPP has completed standardization of Long Term Evolution vehicle (Long Term Evolution vehicle X, LTE-V2X for short) information exchange with the outside. Among them, the 3GPP protocol determines that there are two ways for LTE-V2X communication, namely, through the air interface (PC5) between terminals that communicate directly, and also through the LTE-Uu port. The method of direct communication between nodes through the PC5 port can be classified into a network centralized control Mode (Mode 3) method and a distributed control Mode (Mode 4) method according to the control method of the network to the nodes.

Further, V2X communication shares a carrier with cellular communication or uses a dedicated carrier. In the coverage of a 4G network (E-UTRAN), a V2X communication node determines whether the node uses a Mode3 Mode or a Mode4 Mode according to configuration Information in received signaling, where the specific signaling includes a System Information Block21 (System Information Block21, abbreviated as SIB21) and a Radio Resource Control (RRC) reconfiguration message.

If the V2X communication node enters the Mode3, the UE may report a message to notify the base station of the following information: the information includes longitude and latitude geographic position information, service sending period, maximum packet size of service packet, service priority and the like. The base station (eNB) notifies the V2X communication node sidelink of resources required for transmitting control information and data information through DCI Format 5A for the V2X communication node communicating at PC5 port.

Currently, NR Uu has also been standardized in 3GPP, but standardization work for NR sidelink supporting NR V2X has not yet started. The mobile communication is updated more quickly, and operators are also accelerating to build infrastructure related to NR Uu, so that the coverage of NR Uu will gradually expand from hot-spot coverage in the future, and even gradually replace LTE cellular networks after coexisting with LTE cellular networks for a period of time. Among them, the development and replacement of automobile and road infrastructure is much slower than the rapid change of mobile communication. The front-mounted vehicle-mounted terminal and the roadside terminal which support LTE sidelink and appear on the market at present exist before vehicles are scrapped or roadside equipment is scrapped. With the development of terminals and the infrastructure construction of NR cellular networks, terminals supporting only LTE sidelink may also support NR Uu. In the future, even if the NR sidelink is standardized to form a product, in order to perform interconnection and interworking with a terminal which only supports LTE sidelink in the previous stage, the NR sidelink and the LTE sidelink are simultaneously supported, and only NR sidelink communication can be performed until the terminal which only supports LTE sidelink completely disappears. The intermediate transition phase may be relatively lengthy.

However, at least the following problems arise during the transition phase:

for example, LTE sidelink mode3UE can be scheduled by LTE network and NR network at the same time, if a part of LTE sidelink mode3UE accepts LTE network scheduling and another part of LTE sidelink mode3UE accepts NR network scheduling, there may be a case where eNB and gNBA allocate the same LTE sidelink mode3 resource to different UE, thereby causing unreasonable resource allocation and further reducing data transmission efficiency.

step 101: and sending resource indication information to a second base station, wherein the resource indication information is used for determining a second resource pool which can be scheduled by the second base station.

Wherein the second resource pool is not conflicted with a first resource pool that the first base station can schedule. Preferably, the first resource pool is a Uu transmission resource pool or a sidelink transmission resource pool, and the second resource pool is a Uu transmission resource pool or a sidelink transmission resource pool. The Uu transmission refers to transmission over a Uu interface, and the Uu interface refers to an air interface between the terminal and the base station.

In addition, the first base station and the second base station may have the same or different technical characteristics. Specifically, the technical characteristics are as follows:

support for LTE Uu;

support for NR Uu;

support the configuration of LTE sidelink UEs as mode3 UEs;

supporting receiving a resource request of an LTE sidelink mode3 UE;

supporting the allocation of resources for LTE sidelink mode3 UE;

supporting the sending of control signaling for LTE sidelink mode3 UE;

supporting receiving a resource request of an NR sidelink mode 1 UE;

supporting the allocation of resources for NR sidelink mode 1 UE;

the method comprises the steps that the UE supporting the NR sidelink mode 1 sends a control signaling;

scheduling of resource pools for NR sidelink mode2 UEs is supported.

Preferably, the first base station and the second base station may interact with each other through an X2 interface, an Xn interface, an S1 interface, an NG interface, or an interface with the operation management maintenance entity, and therefore, the first base station may send the resource indication information to the second base station through an X2 interface, an Xn interface, an S1 interface, an NG interface, or an interface with the operation management maintenance entity.

When the resource pools which can be scheduled by the two base stations are located in different target resource pools and are not overlapped in the time domain, the mutual interference between the resource pools which can be scheduled by the two base stations can be reduced, and thus the transmission efficiency of data is improved. Similarly, when the resource pools which can be scheduled by the two base stations are located in different target resource pools and are not overlapped in the frequency domain, the mutual interference between the resource pools which can be scheduled by the two base stations can be reduced, so that the data transmission efficiency is improved.

The first target resource pool described in the first embodiment and the second embodiment is a resource pool of LTE sidelink mode3 or a resource pool of NR sidelink mode 1.

It should be noted here that, in the LTE network system, when there are both LTE sidelink mode3 and LTE eidelink mode4, there may be NR sidelink mode 1 in the NR network system; in an LTE network system, when an LTE sidelink mode3 and an LTE sidelink mode4 exist at the same time, an NRsidelink mode2 may exist in an NR network system; in the NR network system, when there are NR sidelink mode 1 and NR sidelink mode2 at the same time, there may be LTE sidelink mode3 in the LTE network system; in the NR network system, when NRsidelink mode 1 and NR sidelink mode2 coexist, LTE sidelink mode4 may exist in the LTE network system. Therefore, for the second target resource pool and the third target resource pool, the following combination may be specifically used:

The second target resource pool is a resource pool of an LTE sidelink mode3, and the third target resource pool is a resource pool of an NRsidelink mode 2; or

The second target resource pool is a resource pool of an LTE sidelink mode4, and the third target resource pool is a resource pool of an NRsidelink mode 1;

the second target resource pool is a resource pool of LTE sidelink mode4, and the third target resource pool is a resource pool of NRsidelink mode 2.

In addition, the resource pool may also be a Uu transmission resource pool, and various combinations are more, which are not listed here.

As can be seen from the first and second embodiments, when the first base station is an eNB and the second base station is a gNB, the following specific embodiments are given for resource allocation.

For example, the eNB and the gNB interact with each other, so that LTE sidelink mode3 resource pools scheduled by the eNB and the gNB do not overlap, and the specific implementation manner is as follows:

the first method is as follows: the eNB selects a first resource pool which can be scheduled by the eNB from the LTE sidelink mode3 resource pools and sends the first resource pool to the gNB, so that the gNB selects a second resource pool which is scheduled by the gNB from the rest LTE sidelink mode3 resource pools; or

The eNB selects a first resource pool which can be scheduled by the eNB from the LTE sidelink mode3 resource pools, then selects a second resource pool which can be scheduled by the gNB from the rest resource pools in the LTEeidelink mode3 resource pools, and sends the information of the second resource pool to the gNB.

The second method comprises the following steps: the LTE sidelink mode3 resource pool allocation principle is predetermined, for example, the resource pools are divided according to the relative position relationship of the resource pools, so that the resource pools of the eNB and the gNB are in odd number and even number, the eNB selects a first resource pool which can be scheduled in the LTE sidelink mode3 resource pools according to the predetermined allocation principle, and sends the predetermined allocation principle to the gNB, so that the gNB selects a second resource pool which can be scheduled in the LTE sidelink mode3 resource pools according to the allocation principle; or

The eNB selects a first resource pool which can be scheduled by the eNB from the LTE sidelink mode3 resource pools according to a predetermined allocation principle, selects a second resource pool which can be scheduled by the gNB, and then sends the second resource pool to the gNB.

The third method comprises the following steps: the allocation principle and reference information of the LTE sidelink mode3 resource pool are predetermined, for example, the LTE sidelink mode3UE in the coverage of the base station is divided according to the number and/or the traffic proportion of the LTE sidelink mode3UE, and then the eNB sends the number and/or the traffic of the LTE sidelink mode3UE in the coverage of the eNB to the gNB, so that the gNB selects resource pools which can be scheduled for the eNB and the gNB in the LTE sidelink mode3 resource pool according to the number and/or the traffic of the LTE sidelink mode3UE in the coverage of the eNB and the number and/or the traffic proportion of the LTE sidelink mode3UE in the coverage of the eNB; or

The eNB receives the number and/or the traffic of the LTE sidelink mode3UE covered by the gNB and sends the number and/or the traffic to the gNB, and then resource pools which can be scheduled are respectively selected for the eNB and the gNB in the LTE sidelink mode3 resource pools according to the ratio of the number and/or the traffic of the LTE sidelink mode3UE covered by the eNB and the number and/or the traffic of the LTE sidelink mode3UE covered by the gNB, so that the resource pools selected for the gNB are sent to the gNB.

It should be noted that, in each of the above manners, the eNB may establish the request before starting the interaction with the gNB, where an initiator of the request may be any party, and may initiate the request periodically or initiate the event-triggered request. And after one party receives the information sent by the other party, a confirmation message can also be replied. Furthermore, the resource allocation principle and the reference information may be pre-configured, pre-negotiated with each other, or suggested by one party.

For another example: the eNB and the gNB interact with each other, so that the LTE sidelink resource pool scheduled by the eNB and the NRsidelink resource pool scheduled by the gNB do not overlap in a time domain, and the specific implementation mode is as follows:

the first method is as follows: assuming that the eNB knows the resource pool of the LTE sidelink and the gNB knows the resource pool of the NR sidelink, the eNB firstly selects a first resource pool which can be scheduled by the eNB from the resource pool of the LTE sidelink, and then the eNB sends the information of the first resource pool to the gNB, so that the gNB selects a second resource pool which can be scheduled by the gNB and is not overlapped with the first resource pool in the time domain from the NR sidelink resource pool; or

The eNB firstly selects a first resource pool which can be scheduled by the eNB from the resource pools of the LTE sidelink, and then selects a second resource pool which can be scheduled by the gNB and is not overlapped with the first resource pool in time domain from the NRsidelink resource pools, so that the information of the second resource pool is sent to the gNB.

The second method comprises the following steps: assuming that an eNB knows a resource pool of an LTE sidelink, a gNB knows a resource pool of an NR sidelink, and an allocation principle for selecting a first resource pool for the eNB is predetermined, the eNB selects a first resource pool which can be scheduled by the eNB from the resource pools of the LTE sidelink according to the allocation principle, and then sends information of the first resource pool to the gNB, so that the gNB selects a second resource pool which can be scheduled by the gNB and is not overlapped with a time domain of a first resource from the NR sidelink resource pools according to time domain information of the first resource; or

And the eNB sends the allocation principle to the gNB, so that the gNB selects a first resource pool which can be scheduled by the eNB from the resource pools of the LTE sidelink according to the allocation principle, and then selects a second resource pool which can be scheduled by the gNB and is not overlapped with the time domain of the first resource from the resource pools of the NR sidelink according to the time domain information of the first resource pool.

The third method comprises the following steps: assuming that an eNB knows a resource pool of an LTE sidelink, a gNB knows a resource pool of an NR sidelink, and an allocation principle for selecting a first resource pool for the eNB and required reference information are predetermined, the eNB acquires the required reference information, and then selects a first resource pool which can be scheduled by the gNB from the resource pool of the LTE sidelink according to the allocation principle and the reference information, so that the gNB selects a second resource pool which can be scheduled by the gNB and is not overlapped with a time domain of a first resource from the resource pool of the NR sidelink according to time domain information of the first resource; or

The eNB acquires the required reference information, and then sends the allocation principle and the reference information to the gNB, so that the gNB selects a first resource pool which can be scheduled by the eNB from the resource pools of the LTE sidelink according to the allocation principle, and then selects a second resource pool which can be scheduled by the gNB and is not overlapped with the time domain of the first resource from the resource pools of the NR sidelink according to the time domain information of the first resource pool.

The method is as follows: assuming that the eNB knows the resource pool of LTE sidelink, the gNB knows the resource pool of NR sidelink, and an allocation principle is predetermined, for example, the allocation principle specifies that the resource pools of the eNB and the gNB are odd-even-numbered, the eNB may select a first resource pool that the eNB can schedule from the resource pool of LTE sidelink directly according to the allocation principle, and the gNB selects a second resource pool that the gNB can schedule from the resource pool of NR sidelink according to the allocation principle; or

The eNB sends a predetermined allocation principle to the gNB, the gNB selects a first resource pool which can be scheduled by the gNB from the resource pools of the LTE sidelink according to the allocation principle, and the gNB selects a second resource pool which can be scheduled by the gNB from the resource pools of the NR sidelink.

The fifth mode is as follows: assuming that an eNB knows a resource pool of an LTE sidelink, a gNB knows a resource pool of an NR sidelink, and a distribution principle and required reference information are predetermined, the eNB acquires the required reference information, then selects a first resource pool which can be scheduled by the eNB from the resource pool of the LTE sidelink according to the distribution principle and the reference information, and selects a second resource pool which can be scheduled by the gNB from the NRsidelink resource pool; or

The eNB acquires the required reference information and sends the allocation principle and the reference information to the gNB, so that the gNB selects a first resource pool which can be scheduled by the eNB from resource pools of the LTEcidelink, and the gNB selects a second resource pool which can be scheduled by the gNB from the NR sidelink resource pools.

For another example: the eNB and the gNB interact with each other, so that the LTE sidelink resource pool scheduled by the eNB and the NRsidelink resource pool scheduled by the gNB do not overlap in the frequency domain, and the specific implementation manner is as follows:

the first method is as follows: assuming that the eNB knows the resource pool of the LTE sidelink and the gNB knows the resource pool of the NR sidelink, the eNB firstly selects a first resource pool which can be scheduled by the eNB from the resource pool of the LTE sidelink, and then the eNB sends the information of the first resource pool to the gNB, so that the gNB selects a second resource pool which can be scheduled by the gNB and does not overlap the first resource pool on the frequency domain from the NR sidelink resource pool; or

The eNB firstly selects a first resource pool which can be scheduled by the eNB from the resource pools of the LTE sidelink, and then selects a second resource pool which can be scheduled by the gNB and is not overlapped with the first resource pool on the frequency domain from the NRsidelink resource pools, so that the information of the second resource pool is sent to the gNB.

The second method comprises the following steps: assuming that an eNB knows a resource pool of an LTE sidelink, a gNB knows a resource pool of an NR sidelink, and an allocation principle for selecting a first resource pool for the eNB is predetermined, the eNB selects a first resource pool which can be scheduled by the gNB from the resource pools of the LTE sidelink according to the allocation principle, and then sends information of the first resource pool to the gNB, so that the gNB selects a second resource pool which can be scheduled by the gNB and is not overlapped with a frequency domain of a first resource from the NR sidelink resource pools according to the frequency domain information of the first resource; or

And the eNB sends the allocation principle to the gNB, so that the gNB selects a first resource pool which can be scheduled by the eNB from the resource pools of the LTE sidelink according to the allocation principle, and then selects a second resource pool which can be scheduled by the gNB and is not overlapped with the frequency domain of the first resource from the resource pools of the NR sidelink according to the frequency domain information of the first resource pool.

The third method comprises the following steps: assuming that an eNB knows a resource pool of an LTE sidelink, a gNB knows a resource pool of an NR sidelink, and an allocation principle for selecting a first resource pool for the eNB and required reference information are predetermined, the eNB acquires the required reference information, and then selects a first resource pool which can be scheduled by the gNB from the resource pool of the LTE sidelink according to the allocation principle and the reference information, so that the gNB selects a second resource pool which can be scheduled by the gNB and is not overlapped with the frequency domain of the first resource from the resource pool of the NR sidelink according to the frequency domain information of the first resource; or

The eNB acquires the required reference information, and then sends the allocation principle and the reference information to the gNB, so that the gNB selects a first resource pool which can be scheduled by the eNB from the resource pools of the LTE sidelink according to the allocation principle, and then selects a second resource pool which can be scheduled by the gNB and is not overlapped with the frequency domain of the first resource from the resource pools of the NR sidelink according to the frequency domain information of the first resource pool.

In addition, when selecting the first resource pool that the first base station can schedule and the second resource pool that the second base station can schedule according to the allocation principle or the allocation principle and the reference information, the method is not limited to first select the first resource pool according to the allocation principle or the allocation principle and the reference information, and then select the second resource pool by referring to the first resource pool, and may also be: firstly, selecting a second resource pool according to an allocation principle or the allocation principle and reference information, and then selecting a first resource pool according to the second resource pool; and simultaneously selecting the first resource pool and the second resource pool according to the allocation principle, the allocation principle and the reference information. That is, the allocation principle or the allocation principle and the reference information are not limited to be used only for selecting the first resource pool, simultaneously selecting the first resource pool and the second resource pool, but also used only for selecting the second resource pool.

In addition, the above example is that two base stations interact with each other, and the interaction between multiple base stations can be regarded as multiple pairwise interactions. Moreover, the above is an example of two base stations scheduling one resource pool or two resource pools, and the analogy can be given for the case that two base stations schedule more than two resource pools.

For example, the following may be given for two base stations to schedule three resource pools:

the first base station selects a first resource pool which can be scheduled in a second target resource pool, selects a third resource pool which can be scheduled in the third target resource pool, and selects a second resource pool which can be scheduled by a second base station in a fourth target resource pool, wherein the time domains of the first resource pool and the second resource pool are not overlapped, the frequency domains of the first resource pool and the third resource pool are not overlapped, and the time domains and the frequency domains of the second resource pool and the third resource pool are not overlapped.

It can be seen that the first resource pool and the second resource pool selected for the first base station may include a portion where only the time domain does not overlap, a portion where only the frequency domain does not overlap, and a portion where neither the frequency domain nor the time domain overlaps. That is, in the first embodiment and the second embodiment, specific methods for selecting the first resource pool that can be scheduled by the first base station and the resource pool that can be scheduled by the second base station may be combined with each other.
