Referring to FIG. 2, FIG. 2 is a schematic flowchart of an uplink scheduling method according to the first embodiment of the present invention. As shown in FIG. 2, the uplink scheduling method specifically includes the following steps:

S201. The base station sends downlink signaling to the user equipment UE, where the downlink signaling is signaling that the UE needs to perform an uplink response for the downlink signaling.

The downlink signaling may be RRC signaling, NAS (Non Access Stratum) signaling, TCP (Transmission Control Protocol) signaling, or FTP (File Transfer Protocol) signaling. Order and so on.

The downlink signaling is a signaling that the UE needs to perform an uplink response to the downlink signaling, and may be determined by the base station. Optionally, the determining, by the base station, whether the downlink signaling is the signaling that the UE needs to perform the uplink response to the downlink signaling, the determining, by the base station, determining, according to the attribute information of the downlink signaling, whether the downlink signaling is a preset If yes, the base station determines that the downlink signaling is signaling that the UE needs to perform an uplink response for the downlink signaling; if not, the base station determines that the downlink signaling is not a message that the UE needs to perform uplink response for the downlink signaling. make. The attribute information of the downlink signaling may include the identifier, type, name, and the like of the downlink signaling. The foregoing preset signaling may be, for example, RRC Connection Reconfiguration, RRC Connection Setup signaling, RRC Connection Reestablishment, Security Mode Command. Order), UE Capability Enquiry, Counter Check, UE Information Request, RN Reconfiguration, etc.

Preferably, the base station determines whether the downlink signaling is the signaling that the UE needs to perform the uplink response for the downlink signaling, and the RLC entity of the base station identifies whether the downlink signaling is downlink (DL) signaling wireless. Signaling Radio Bearer (SRB) signaling (excluding the case where the RLC Protocol Data Unit (PDU) packet has only the RLC status report), and if so, the RLC entity of the base station sets the flag bit SRBFlag of the MAC entity interface of the base station. True; if not, the RLC entity of the base station sets the flag bit SRBFlag of the MAC entity interface of the base station to False. When the MAC entity of the base station recognizes that the flag bit SRBFlag of the MAC entity interface of the base station is set to True, the downlink is determined. The signaling is that the UE needs to perform uplink response signaling for the downlink signaling. When the MAC entity identifies that the flag of the MAC entity interface, SRBFlag, is set to False, the downlink signaling is determined not to be required for the downlink signaling. Signaling of the uplink response.

S202. If the base station determines that the uplink response sent by the UE is not received within a preset time period, the base station allocates an uplink scheduling resource to the UE.

Optionally, the foregoing preset time period is determined by the base station according to the uplink response.

Optionally, the specific implementation manner for the base station to allocate the uplink scheduling resource to the UE is: the base station determines the specification of the uplink response; and the base station allocates, to the UE, the uplink scheduling resource that matches the specification of the uplink response.

Optionally, the method for the base station to allocate the uplink scheduling resource to the UE is: the base station allocates, to the UE, the uplink scheduling resource whose demodulation threshold is lower than or equal to a preset demodulation threshold.

The uplink scheduling resource includes a time-frequency resource location (a time location and a frequency location). Optionally, the foregoing uplink scheduling resource may further include a time domain length, a frequency domain width, an identifier of the UE, and the like. The above time position is used by the UE to transmit data at the time position. The above frequency location is used by the UE to transmit data on the carrier of the frequency location. The time domain length is the number of subframes occupied by the uplink scheduling resource. The frequency domain width is a frequency range in which the uplink scheduling resource occupies a carrier. The identifier of the UE may be a Cell Radio Network Temporary Identifier (C-RNTI) or a SAE Temporary Mobile Station Identifier (S-TMSI). The identity of the UE is used to distinguish the scheduling resources allocated by the base station. The subsequent base station sends a resource allocation notification to the UE, and the UE may determine, according to the identifier of the UE, the uplink scheduling resource allocated by the base station to the UE.

It can be seen that, in the embodiment of the present invention, if the downlink signaling sent by the base station to the UE is the signaling that the UE needs to perform the uplink response for the downlink signaling, and the base station does not receive the uplink response sent by the UE within the preset time period. When the base station actively gives the UE an opportunity to actively schedule the UE, it can avoid the problem that the UE fails to send the uplink response and causes the UE to fail to access or drop the call, thereby improving the UE access success rate or reducing the call drop rate.

Optionally, before the determining, by the base station, that the uplink response that is sent by the UE is not received in the preset time period, the uplink scheduling method shown in FIG. 1 further includes: acquiring, by the base station, the UE, Confirmation ACK information of downlink signaling.

Optionally, before the base station sends the resource allocation notification to the UE, the uplink scheduling method shown in FIG. 1 further includes: determining, by the base station, whether the UE meets a resource allocation condition according to the channel state information reported by the UE; The UE satisfies a resource allocation condition, and the base station allocates an uplink scheduling resource to the UE.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of an uplink scheduling method according to a second embodiment of the present invention. As shown in FIG. 3, the uplink scheduling method specifically includes the following steps:

S301. The base station sends downlink signaling to the user equipment UE, where the downlink signaling is signaling that the UE needs to perform an uplink response for the downlink signaling.

For the specific implementation of the step S301, refer to the related description of the step S201 in the uplink scheduling method disclosed in the first embodiment of the present invention, and details are not described herein again.

S302. The base station acquires acknowledgement ACK information that the UE receives the downlink signaling.

In a specific implementation, the control signaling (such as an acknowledgment (ACK), an SR, etc.) is uploaded to the base station through a Physical Uplink Control Channel (PUCCH). The UE has a specific location on the PUCCH. When the UE transmits the ACK information at the specific location, the base station may acquire the ACK information of the UE at the specific location, and if the ACK is 1, the acknowledgement is valid, then step S303 is performed. When the ACK is 0, the acknowledgment is invalid, and the base station initiates a hybrid automatic repeat reQuest (HARQ, HARQ).

S303. The base station determines whether the uplink response sent by the UE is not received within a preset time period.

If so, do nothing.

If no, step S304 is performed.

Preferably, the specific implementation manner of the base station determining whether the uplink response is not received by the UE in the preset time period may be: the base station determines whether the uplink control plane data of the SRB2 is received within the preset time period (uplink control) The area data includes uplink (UL) signaling radio bearers (SRB) signaling, the base station receives the uplink SRB signaling of the SRB2 indicating that the base station receives the uplink signaling of the downlink signaling, or the base station determines whether it is Receiving the UL SRB signaling of the SRB1 in the foregoing preset period (the UL SRB signaling of the SRB1 received by the base station indicates that the base station receives the signaling response of the RRC peer layer, that is, the uplink response of the downlink signaling is received); The base station determines that the uplink response sent by the UE is not received within a preset time period; if yes, the base station determines that the uplink response sent by the UE is received within a preset time period, where SRB1 and SRB2 are both signaling wireless Bearer, SRB1 is used to carry RRC signaling (may also carry NAS signaling, but the NAS signaling is related to RRC signaling), and SRB2 is used to carry NAS signaling.

Optionally, the start time node of the preset time period may be a time node when the base station receives the ACK information of the UE.

Optionally, the foregoing preset time period may be implemented by the base station by using a timer corresponding to the UE. For example, when the base station acquires the acknowledgement ACK information (ACK 1) of the downlink signaling received by the UE, the base station initiates the UE corresponding. The timer has a timer duration of the preset period.

The foregoing preset time period is determined by the base station according to the uplink response. The specific implementation manner of determining, by the base station, the preset time period according to the uplink response is determined by the base station according to the foregoing uplink response, for example, the base station determines the preset time period according to the mapping relationship between the signaling size and the duration; or, the base station determines according to the uplink response. The specific implementation manner of the foregoing preset time period is: the base station is determined according to the attribute information of the uplink response, where the attribute information of the uplink signaling may include the identifier, type, name, and the like of the uplink signaling, for example, the base station according to the information The mapping relationship between the type of the order and the duration determines the preset time period.

S304. The base station allocates an uplink scheduling resource to the UE.

In an embodiment of the present invention, the base station allocates an uplink scheduling resource to the UE, where the base station determines the uplink response specification, and the base station allocates, to the UE, an uplink scheduling resource that matches the foregoing uplink signaling specification. Preferably, the base station can know the specific signaling of the uplink response, and can further know the specification of the uplink response (such as the size of the uplink response). In order to make the resources allocated to the UE sufficient and not waste, the base station can respond according to the foregoing uplink response. The mapping relationship between the size and the size of the uplink scheduling resource is to allocate the uplink scheduling resource that matches the size of the uplink response to the UE.

In another embodiment of the present invention, there is a case that after receiving the downlink signaling sent by the base station, the UE has initiated an SR to the base station, and after receiving the SR initiated by the UE, the base station allocates an uplink scheduling resource to the UE. However, the uplink response sent by the UE may not be successfully sent for some reason (for example, the uplink scheduling resource allocated by the base station cannot be sufficient for the UE to send the uplink response to the base station), thereby causing the base station not to receive the UE within the preset time period. The uplink response is sent. In this case, the base station allocates an uplink scheduling resource to the UE. The base station allocates, to the UE, an uplink scheduling resource whose demodulation threshold is lower than or equal to a preset demodulation threshold. Preferably, the base station acquires a demodulation threshold of the uplink scheduling resource allocated to the UE last time; the base station uses the demodulation threshold as a preset demodulation threshold; and the base station allocates a demodulation threshold to the UE that is lower than or equal to a preset demodulation threshold. Upstream scheduling resources.

Optionally, before the step S304, the uplink scheduling method shown in FIG. 3 further includes: determining, by the base station, whether the UE meets the resource allocation condition according to the channel state information reported by the UE; and if the UE meets the resource allocation condition, the base station allocates the uplink to the UE. Schedule resources.

In a specific implementation, before the base station allocates uplink scheduling resources to the UE, the base station needs to know the UE calendar. The channel state, when the UE has a good channel quality and the UE needs to transmit data, the base station allocates uplink scheduling resources to the UE. Therefore, before the base station allocates the uplink scheduling resource to the UE, the base station needs to determine whether the UE meets the resource allocation condition. The specific implementation manner may be: the base station determines, according to the channel state information (CSI) reported by the UE, whether the UE meets the resource allocation condition. If the UE meets the resource allocation condition, the base station allocates an uplink scheduling resource to the UE. The CSI includes a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), and a Rank Indicator (RI). For example, the base station may determine whether the value of the CQI is greater than or equal to a preset threshold. If yes, it indicates that the UE meets the resource allocation condition, and the preset threshold may be 15, 20, 24, 25, 28 or other values.
