Description

Uplink resource allocation method and device

The present invention relates to the field of communications technologies, and in particular, to an uplink resource allocation method and apparatus. Background technique

In the LTE (Long Term Evolution) system, the PDSCH is controlled by the base station (e B )

(Physical Downlink Shared Channel, downlink physical shared channel) and PUSCH (Physical Uplink Shared Channel). When the user equipment (UE) needs to send uplink data, the amount of the uplink data to be sent may be notified to the base station by using a BSR (Buffer Status Report), where the BSR is encapsulated in a MAC (Media Access Control, media connection). In the PDU (Protocol Data Unit), the PUCCH (Physical Uplink Control Channel) carries the bearer. When there is no uplink resource PUSCH to carry the BSR, the UE sends the SR (Scheduling Request) on the PUCCH. The scheduling request is sent to inform the base station that the UE is waiting to be transmitted by data, and the PUCCH resources of the multiple UEs may be multiplexed on one physical layer RB (Resource Block).

The inventor has found that in the prior art, the base station configures a dedicated PUCCH for transmitting an SR for each UE, which may also be called an SR-PUCCH, and the UE sends an SR on the SR-PUCCH. In order to enable the base station to receive the SR, the uplink scheduling may be performed by the UE-specific C-RNTK Cell-Radio Network Temporary Identifier. In the prior art, since the base station needs to separately configure one SR-PUCCH resource for each UE, when the SR transmission requirement of the system is small, the resource utilization of the SR-PUCCH is not high, thereby causing waste of system resources. Summary of the invention

The embodiments of the present invention provide an uplink resource allocation method and device, so as to solve the problem that the resource utilization of the SR-PUCCH in the prior art is not high, resulting in wasted system resources.

DETAILED DESCRIPTION OF THE INVENTION The following embodiments provide an uplink resource allocation method and apparatus to improve the utilization of uplink scheduling request channel resources in the system and reduce waste of system resources.

The above-mentioned objects, features, and advantages of the embodiments of the present invention will become more apparent and understood. Give further details.

Referring to FIG. 1, which is a flowchart of an embodiment of an uplink resource allocation method according to the present invention, the embodiment describes a process of uplink resource allocation from a base station side:

Step 101: The base station saves configuration information of an uplink scheduling request channel resource configured for each UE, where each UE configures at least two uplink scheduling request channel resources, where the number of UEs is smaller than the uplink tone The number of requested channel resources.

In the embodiment of the present invention, the uplink scheduling request channel resource may include at least one of the following resources: SR-PUCCH (scheduling request-physical uplink control channel), preamble in PRACH (Physical Random Access Channel) Pilot code).

Each of the uplink scheduling request channel resources can be shared by at least two UEs, thereby further improving the utilization of the uplink scheduling request channel resources and reducing the waste of system resources.

Step 102: After receiving the scheduling request SR sent by the UE through the configured at least two uplink scheduling request channel resources, the base station determines, according to the configuration information, the UE that sends the SR.

When the uplink scheduling request channel resource configured by the base station for the UE is the SR-PUCCH, the UE sends the SR through the SR-PUCCH. When the uplink scheduling request channel resource configured by the base station for the UE is the preamble of the PRACH, the UE passes the The SR is sent by a dedicated preamble code on the PRACH.

Specifically, the base station searches for the saved configuration information according to the received uplink scheduling request channel resource, and acquires a UE set corresponding to each uplink scheduling request channel resource, where the UE set includes the UE configured with the uplink scheduling request channel resource, and compares Obtaining the UE set, obtaining an intersection of the UE set according to the comparison result, and determining the UE in the intersection as the UE transmitting the SR.

Step 103: The base station allocates an uplink resource to the determined UE.

After determining the UE that sends the SR, the base station may allocate a dedicated uplink resource to the UE through the C-RNTI dedicated to the UE, so that the UE completes the uplink data transmission by using the uplink resource.

It can be seen that the foregoing embodiments do not need to configure a separate uplink scheduling request channel resource for each UE, but multiple UEs can share the uplink scheduling request channel resource, and the number of UEs is smaller than the number of uplink scheduling request channel resources, so The uplink scheduling request channel resource utilization in the system reduces the waste of system resources; and, since each UE is configured with at least two uplink scheduling request channel resources, the UE sends the SR through the configured at least two uplink scheduling request channel resources. After the base station can determine the UE that sends the SR according to the configuration information, the base station can accurately determine the UE that needs to be scheduled in the uplink, while improving the utilization of the uplink scheduling request channel resource. Referring to FIG. 2, it is a flowchart of another embodiment of an uplink resource allocation method according to the present invention. The embodiment details the process of uplink resource allocation from the base station side:

Step 201: The base station saves configuration information of an uplink scheduling request channel resource configured for each UE, where each UE configures at least two uplink scheduling request channel resources, and each uplink scheduling request channel resource is shared by at least two UEs. The number of UEs is less than the number of uplink scheduling request channel resources. In the embodiment of the present invention, the uplink scheduling request channel resource may include at least one of the following resources:

SR-PUCCH (scheduling request-physical uplink control channel), preamble (pilot code) in PRACH (Physical Random Access Channel).

Step 202: The base station sends at least two uplink scheduling request channel resources configured for each UE to the UE by using an RRC message.

In the embodiment of the present invention, the RRC (Radio Resource Control) message may include: an RRC connection setup message (RRC Connection Setup), an RRC connection reconfiguration message (RRC Connection Reconfiguration), and an RRC connection re-establishment message (RRC Connection). Reestablishment ₀ The RRC message is only used for the convenience of the description in the embodiment of the present invention, and is not used to limit the embodiment of the present invention, as long as the message can send the configuration information to the UE.

Step 203: The base station receives a scheduling request SR that is sent by the UE through the configured at least two uplink scheduling request channel resources.

Step 204: The base station searches for the saved configuration information according to the received uplink scheduling request channel resource, and acquires a UE set corresponding to each uplink scheduling request channel resource, where the UE set includes the UE configured with the received uplink scheduling request channel resource. .

Step 205: Compare all UE sets, obtain an intersection of the UE set according to the comparison result, and determine the UE of the intersection as the UE that sends the SR.

Step 206: The base station allocates an uplink resource to the determined UE.

It can be seen that the foregoing embodiments do not need to configure a separate uplink scheduling request channel resource for each UE, but multiple UEs can share the uplink scheduling request channel resource, and the number of UEs is smaller than the number of uplink scheduling request channel resources, so The uplink scheduling request channel resource utilization in the system reduces the waste of system resources; and, since each UE is configured with at least two uplink scheduling request channel resources, the UE sends the SR through the configured at least two uplink scheduling request channel resources. After the base station can determine the UE that sends the SR according to the configuration information, the base station can accurately determine the UE that needs to be scheduled in the uplink, while improving the utilization of the uplink scheduling request channel resource. Referring to FIG. 3, it is a flowchart of another embodiment of an uplink resource allocation method according to the present invention. This embodiment describes a process of uplink resource allocation from a UE side:

Step 301: The UE saves configuration information of an uplink scheduling request channel resource configured by the base station for the UE, and the base station configures at least two uplink scheduling request channel resources for the UE.

The UE receives an RRC message sent by the base station, where the RRC message includes an uplink scheduling request channel resource configured by the base station for the UE. In the embodiment of the present invention, the RRC (Radio Resource Control) message may include: an RRC connection setup message (RRC Connection Setup), an RRC connection reconfiguration message (RRC Connection Reconfiguration), and an RRC connection re-establishment message (RRC Connection). Reestablishment). The foregoing RRC message is only used for the convenience of the description in the embodiment of the present invention, and is not used to limit the embodiment of the present invention, as long as the message can send the configuration information to the UE.

Step 302: When the UE needs to send uplink data, send the SR to the base station according to the uplink scheduling request channel resource configured for the UE in the configuration information.

Step 303: The receiving base station allocates an uplink resource to the UE according to the SR.

After determining the UE that sends the SR, the base station may allocate a dedicated uplink resource to the UE by using the C-RNTI dedicated to the UE. After receiving the uplink resource allocated by the base station, the UE completes the uplink data transmission by using the uplink resource.

It can be seen that the foregoing embodiments do not need to configure a separate uplink scheduling request channel resource for each UE, but multiple UEs can share the uplink scheduling request channel resource, and the number of UEs is smaller than the number of uplink scheduling request channel resources, so The uplink scheduling request channel resource utilization in the system reduces the waste of system resources; and, since each UE is configured with at least two uplink scheduling request channel resources, the UE sends the SR through the configured at least two uplink scheduling request channel resources. After the base station can determine the UE that sends the SR according to the configuration information, the base station can accurately determine the UE that needs to be scheduled in the uplink, while improving the utilization of the uplink scheduling request channel resource. The following describes an embodiment of the uplink resource allocation method of the present invention by using an application example. Referring to FIG. 4, it is a schematic diagram of configuring an uplink scheduling request channel resource for a UE:

In Figure 4, it is assumed that the uplink scheduling request channel resource is SR-PUCCH, and a total of eight are configured in the system.

SR-PUCCH, which in turn is SR-PUCCH1, SR-PUCCH2 to SR-PUCCH8, and has 16 in the system. The UEs are UE0, UE1 to UE15 in order. As shown in FIG. 4, two SR-PUCCHs are configured for each UE, and each SR-PUCCH is shared by 4 UEs. The specific configuration is as follows:

UE0, UE4, UE8, UE12 share SR-PUCCH1;

UE1, UE5, UE9, UE13 share SR-PUCCH2;

UE2, UE6, UE10, UE14 share SR-PUCCH3;

UE3, UE7, UE11, UE15 share SR-PUCCH4;

UE0, UE1, UE2, UE3 share SR-PUCCH5;

UE4, UE5, UE6, UE7 share SR-PUCCH6;

UE8, UE9, UE10, UE11 share SR-PUCCH7;

UE12, UE13, UE14, UE15 share SR-PUCCH8.

After the foregoing information is configured on the base station, the configuration information of each UE may be sent to the UE through an RRC message. Taking UE0 as an example, it can be seen from the above configuration information that the SR-PUCCH configured by the base station for UE0 includes SR-PUCCH1 and SR-PUCCH5.

When UE0 has uplink data to be transmitted, UE0 first needs to send an SR to the base station to request the base station to allocate dedicated uplink resources for UE0. At this time, the UE0 sends the SR through the SR-PUCCH1 and the SR-PUCCH5 according to the configuration information. After receiving the SR-PUCCH1 and the SR-PUCCH5, the base station searches for the pre-stored configuration information, and the UE set sharing the SR-PUCCH1 includes {UE0, UE4, UE8, UE12}, the set of UEs sharing the SR-PUCCH5 includes {UE0, UE1, UE2, UE3}, and the base station takes the intersection of the two UE sets as {UE0}, whereby the UE can determine the UE0 that sends the SR, so The base station can allocate dedicated uplink resources to UE0 through the C-RNTI of UE0.
