Description

Downlink subframe scheduling method, base station, terminal and system

Technical Field

The present invention relates to the field of communications, and in particular, to a downlink subframe scheduling method, a base station, a terminal, and a system.

Background

In an LTE (long term evolution) system of the existing 3GPP (3 rd generation partnership project), a terminal receives downlink service data and transmits uplink service data at corresponding uplink and downlink resources according to an instruction of a PDCCH (physical downlink control channel) signaling sent by a base station.

In the existing LTE system, a base station schedules a resource of one subframe through PDCCH signaling to perform transmission of service data. For the transmission of downlink service data, the base station sends corresponding scheduling instructions on the PDCCH signaling to schedule downlink subframe resources, and issues the service data on the subframe bearing the scheduling instructions. Specifically, after receiving a downlink MAC (media access control) data packet, the terminal checks whether the data packet is correct through a Cyclic Redundancy Check (CRC) code, and if so, feeds back a correct indication to the base station in a certain fixed subframe after receiving the MAC data packet, and notifies the base station that scheduling of new service data can be started; if the MAC data packet is wrong, the terminal feeds an error indication back to the base station in a certain fixed subframe after receiving the MAC data packet, and the base station retransmits the MAC data packet after receiving the error indication until receiving a correct indication sent by the terminal or giving up retransmitting the MAC data packet after reaching the maximum retransmission times.

With the rapid increase of the indoor MBB (mobile broadband) service demand, some indoor coverage scenarios have the characteristics of small coverage area, few users, and good and stable user channel conditions, and according to the LTE standard, if each PDCCH signaling can only schedule resources of one or a fixed number of subframes, the receiving mode of the terminal needs to be frequently configured according to the data transmission format, which results in large PDCCH signaling overhead of the system and low spectrum efficiency, thereby limiting the system capacity.

301: and the base station sends a notification message to the terminal, wherein the notification message is used for notifying the terminal whether the base station supports sending the service data on the resources of the continuous downlink subframes.

In this embodiment, when the channel state is stable, the transmission channel of the terminal may be configured according to the current channel state, and the service data sent on the resource of the continuous downlink subframe may be received according to the configuration, so as to avoid the problem of frequently configuring the transmission channel.

Specifically, the base station may set a flag bit in the notification message, and identify whether the base station supports sending the service data on the resource of the consecutive downlink subframe through the flag bit, for example, the flag bit is set to 0 to identify that the base station supports sending the service data on the resource of the consecutive downlink subframe, the flag bit is set to 1 to identify that the base station does not support sending the service data on the resource of the consecutive downlink subframe, and the like. Further, the base station may send the notification message to the terminal through RRC (radio resource control) signaling.

302: and the terminal receives the notification message sent by the base station.

The terminal receives the notification message and judges whether the base station supports sending the service data on the resource of the continuous downlink subframe according to the notification message, wherein the judging method is related to the method for setting the notification message by the base station. Taking the method that the base station sets the notification message through the flag bit in 301 as an example, the terminal reads the flag bit in the notification message, if the flag bit is 0, the terminal identifies that the base station supports sending the service data on the resource of the continuous downlink subframe, and the terminal needs to keep track of the indication of the subsequent sending of the base station to determine whether the base station sends the service data on the resource of the continuous downlink subframe; and if the flag bit is 1, identifying that the base station does not support the transmission of the service data on the resources of the continuous downlink subframes, and normally processing the indication transmitted by the base station by the terminal.

303: and the base station generates a PDCCH (physical Downlink control channel) signaling according to the channel state and sets the PDCCH signaling so as to identify that the service data is to be sent on the resources of the scheduled continuous downlink subframes.

The PDCCH signaling is used for describing scheduling, transmission format, occupied frequency band resource and the like of channel resources, so that the terminal configures a receiving mode of the terminal according to the PDCCH signaling after receiving the PDCCH signaling, and the configured receiving mode can receive service data sent by a base station.

In this embodiment, the PDCCH signaling may also be set to identify that service data is to be transmitted on resources of scheduled consecutive downlink subframes.

Specifically, setting the PDCCH signaling to identify that service data is to be transmitted on resources of scheduled consecutive downlink subframes may include:

the base station sets the TPC command of the PDCCH signaling so as to identify that the service data is to be sent on the resource of the scheduled continuous downlink subframe; or,

the base station sets the TPC command and the RV domain so as to identify that service data is to be sent on the resources of the scheduled continuous downlink subframes; or,

Before setting the TPC command, the base station first classifies DCI (downlink control information) corresponding to the PDCCH signaling, where the classification may include, but is not limited to, DCI format1/1 a/1B/1C/1D/2 and the like. The format of each DCI may be different, for example, some DCI categories include TPC commands, and the rest DCI categories do not include TPC commands. In this embodiment, the base station sets the TPC command in all DCI categories, for example, if the TPC command is included in dciformation 1/1A/1B/1D/2, the TPC command in dciformation 1/1A/1B/1D/2 is set. Specifically, the TPC command may be set to "00" to identify that the traffic data is to be transmitted on the resource of the scheduled consecutive downlink subframe, and the like.

Or, the TPC command and the RV field may also be set, specifically, the TPC command may be set to "00" and the RV field may be set to "00" to identify that the service data is to be transmitted on the resource of the scheduled consecutive downlink subframe, and the like.

Or, an activation flag may be added to the PDCCH signaling and set, for example, the activation flag may be set to "0" to identify that service data is to be sent on resources of scheduled consecutive downlink subframes, and the like.

304: and the base station generates a first scheduling indication according to the set PDCCH signaling and sends the first scheduling indication to the terminal.

In this embodiment, in order to facilitate the terminal to determine whether the base station will send service data on resources of consecutive subframes according to the received PDCCH signaling, the terminal may further generate the first scheduling indication according to the set PDCCH signaling.

Specifically, generating the first scheduling indication according to the set PDCCH signaling may include:

the base station scrambles the set PDCCH signaling according to the newly added RNTI to generate a first scheduling indication; or the base station reverses the CRC calculated according to the PDCCH signaling, and generates a first scheduling indication by taking the reversed CRC as the set CRC of the PDCCH signaling.

The base station can add a type of RNTI and send the RNTI to the terminal, so that the terminal can descramble the first scheduling instruction according to the RNTI.

Further, the base station may separately send the first scheduling indication to the terminal, or send the MAC packet corresponding to the first scheduling indication to the terminal, so as to save signaling overhead.

305: and the terminal receives the first scheduling indication and acquires the PDCCH signaling according to the first scheduling indication.

In this embodiment, the method for the terminal to obtain the PDCCH signaling is related to the method for the base station to generate the first scheduling indication in 304. Taking the example that the base station generates the first scheduling indication in 304, the acquiring, by the terminal, the PDCCH signaling may include:

After receiving the first scheduling indication, the terminal descrambles the first scheduling indication according to the conventional RNTI, if the descrambling is correct, the PDCCH signaling obtained by identification is the conventional PDCCH signaling, and the terminal can configure the receiving mode of the terminal according to the conventional PDCCH signaling; and if the descrambling is wrong, the terminal descrambles the first scheduling indication according to the newly added RNTI, and if the descrambling is correct, the PDCCH signaling obtained by the identification is the PDCCH signaling set in the 304. Or, the terminal checks the first scheduling indication according to the conventional CRC, if the first scheduling indication is correct, the PDCCH signaling obtained by the identification is the conventional PDCCH signaling, and the terminal can set the self receiving mode according to the conventional PDCCH signaling; and if the check is wrong, the terminal checks the first scheduling indication according to the reversed CRC, and if the check is correct, the obtained PDCCH signaling is identified as the PDCCH signaling set in the step 304.

306: and the terminal detects the PDCCH signaling and configures the receiving mode of the terminal according to the PDCCH signaling.

In this embodiment, the terminal may further detect the set PDCCH signaling to determine that the base station is to send service data on resources of consecutive downlink subframes.

Specifically, detecting the PDCCH signaling and configuring a receiving mode of the PDCCH signaling according to the PDCCH signaling may include:

The method for detecting the PDCCH signaling is related to the method for setting the PDCCH signaling in 303. Taking PDCCH signaling set in 303 as an example, if the TPC command acquired by the terminal is "00", it is identified that the base station will send service data on resources of consecutive downlink subframes. Or, if the TPC command acquired by the terminal is "00" and the RV domain is "00", the identity base station will send the service data on the resources of the consecutive downlink subframes. Or, if the activation flag bit acquired by the terminal is "0", the identity base station will send the service data on the resource of the continuous downlink subframe.

307: and the base station transmits the service data to the terminal on the resource of the continuous downlink subframe scheduled by the first scheduling indication.

Preferably, the method may further comprise: when transmitting service data to the terminal on the resource of the scheduled continuous downlink subframe, if the channel state changes, the base station updates the PDCCH signaling in the first scheduling indication according to the changed channel state and transmits the updated scheduling update indication to the terminal. Specifically, the base station may update the PDCCH signaling, set the updated PDCCH signaling, and generate a scheduling update instruction according to the set updated PDCCH signaling, where details of a process of specifically generating the scheduling update instruction are described in 303 and 304, and are not described herein.

308: and the terminal receives the service data sent by the base station on the resources of the continuous downlink subframes scheduled by the first scheduling indication.

Correspondingly, the method may further include: and the terminal receives a scheduling updating instruction sent by the base station, performs configuration updating on the receiving mode of the terminal according to the scheduling updating instruction and receives service data according to the receiving mode after the configuration updating. Specifically, the terminal acquires a set updated PDCCH signaling according to the scheduling updating indication, detects the updated PDCCH signaling, and if the terminal determines that the base station updates the resource of the scheduled continuous downlink subframe according to the detection result, the terminal performs configuration updating on the receiving mode of the terminal according to the updated PDCCH signaling and receives service data according to the updated receiving mode.

309: and when the service data is sent, the base station generates a second scheduling instruction for finishing scheduling the resources of the continuous downlink subframes, and sends the second scheduling instruction to the terminal so as to mark that the base station sends the data service to the resources of the continuous downlink subframes.

In this embodiment, the base station may further generate a second scheduling indication to identify the completion of the service data transmission. Specifically, the base station may generate the second scheduling identifier by modifying the first scheduling identifier, for example, the base station may modify a TPC command of the PDCCH signaling to identify that the base station will end scheduling resources of consecutive downlink subframes to transmit service data; or, the base station may modify the TPC command and the RV field to identify that the base station will end scheduling resources of consecutive downlink subframes to perform transmission of service data; or, the base station may modify an activation flag bit newly added in the PDCCH signaling to identify that the base station will end scheduling resources of consecutive downlink subframes to perform service data transmission.

Wherein, the modification method for the PDCCH signaling is related to the setting method for the PDCCH signaling in 303. Taking the PDCCH signaling set in 303 as an example, the base station may modify the TPC command to "11" to identify that the base station will end scheduling resources of consecutive downlink subframes to perform transmission of service data; or, the base station may modify the TPC command to "11" and the RV domain is "11" to identify that the base station will end scheduling resources of consecutive downlink subframes for transmitting the service data; or, the base station may modify the activation flag to "1" to identify that the base station will end scheduling resources of consecutive downlink subframes for transmitting service data, and the like.

Further, the base station may also generate the second scheduling indication according to the modified PDCCH signaling, and the generating method is described in detail in 304, which is not described herein again.

310: and the terminal receives a second scheduling instruction sent by the base station and finishes receiving the service data in the receiving mode according to the second scheduling instruction.

In this embodiment, the terminal may obtain the modified PDCCH signaling, and the detailed obtaining method is described in detail in 305, which is not described herein again.

The terminal can also detect the modified PDCCH signaling to identify that the base station will finish scheduling the resources of the continuous downlink subframes to transmit the data service.

Specifically, the terminal detects the TPC command of the PDCCH signaling to identify that the base station will end scheduling resources of consecutive downlink subframes for data service transmission; or, the terminal detects the TPC command and the RV domain to identify that the base station will finish scheduling resources of continuous downlink subframes to transmit data services; or, the terminal detects an activation flag bit newly added in the PDCCH signaling to identify that the base station will end scheduling resources of consecutive downlink subframes for data service transmission.

The detection method for the PDCCH signaling is related to the setting method for the PDCCH signaling in 309. Taking the PDCCH signaling modified in 309 as an example, if the TPC command detected by the terminal is "11", the identity base station will end scheduling resources of consecutive downlink subframes to transmit service data. Or, if the TPC command detected by the terminal is "11" and the RV domain is "11", the identity base station will end scheduling resources of consecutive downlink subframes for transmitting the service data. Or, if the activation flag bit detected by the terminal is "1", the identity base station will end scheduling resources of consecutive downlink subframes to transmit the service data.

In the method provided by this embodiment, a first scheduling indication of resources of a schedulable continuous downlink subframe is generated according to a channel state of a terminal, and the first scheduling indication is sent to the terminal, so that the terminal configures a reception mode of the terminal according to the first scheduling indication; transmitting traffic data to the terminal on resources of consecutive downlink subframes scheduled by the first scheduling indication; when the service data is sent, generating a second scheduling indication for ending the scheduling of the resources of the continuous downlink subframes, and sending the second scheduling indication to the terminal, so that the terminal ends the service data in the receiving mode, and the terminal can receive the service data sent by the base station through the continuous downlink subframes in the same receiving mode, thereby saving PDCCH signaling overhead, improving spectrum efficiency and improving system capacity.

EXAMPLE III

Referring to fig. 4, the present embodiment provides a downlink subframe scheduling method, where the method includes:

401: and the base station sets a scheduling flag bit in a third MAC PDU subheader of a third MAC data packet and sends the third MAC data packet to the terminal.

In this embodiment, the MAC packet sent by the base station before sending the service data to the terminal on the resource of the consecutive downlink subframe is referred to as a third MAC packet. Specifically, the base station adds the service data to the third MAC packet, and sets a scheduling flag bit in the third MAC pdu subheader. For example, the scheduling flag bit may be set to "0" to identify that the transmission of the service data on the resource of the consecutive downlink subframes is turned on, the scheduling flag bit may be set to "1" to identify that the transmission of the service data on the resource of the consecutive downlink subframes is not turned on, and the like, and the setting of the scheduling flag bit is not limited in this embodiment.

402: and the terminal receives a third MAC data packet sent by the base station and determines to start the reception of the service data on the resources of the continuous downlink subframes according to the scheduling flag bit in the third MAC PDU subheader of the third MAC data packet.

The determination method is related to a method for setting a scheduling flag bit by a base station. Taking the method for setting the scheduling flag bit by the base station in 401 as an example, if the scheduling flag bit acquired by the terminal is "0", the terminal marks that the transmission of the service data on the resource of the continuous downlink subframe is started, and the terminal needs to keep track of the indication of the subsequent transmission by the base station to determine whether the base station transmits the service data on the resource of the continuous downlink subframe; and if the scheduling flag bit acquired by the terminal is set to be 1, identifying that the transmission of the service data on the resource of the continuous downlink subframe is not started, and normally processing the indication of the subsequent transmission of the base station by the terminal.

403: the terminal sends a correct indication to the base station.

If the terminal correctly receives the third MAC packet and acquires the scheduling flag, sending a correct indication to the base station, where the correct indication may be an ACK (Acknowledgement) indication; if the terminal has an error when receiving the third MAC packet, the terminal sends an error indication to the base station in a fixed subframe after receiving the third MAC packet, where the error indication may be a Non-Acknowledgement (NACK) indication, and the base station retransmits the third MAC packet after receiving the NACK until the third MAC packet is correctly sent, or the base station abandons retransmission of the third MAC packet after reaching the maximum retransmission time of the third MAC packet. The retransmission third MAC packet has a higher priority than the new MAC packet.

404: after receiving a correct indication sent by the terminal, the base station determines to start sending the service data on the resources of the continuous downlink subframes.

405: and the base station generates a PDCCH signaling according to the channel state, sets a scheduling flag bit in a first MAC PDU subheader of a first MAC data packet, and sends the PDCCH signaling and the first MAC data packet to the terminal.

In this embodiment, a first MAC packet of service data sent by the base station to the terminal on the resource of the consecutive downlink subframe is referred to as a first MAC packet. In this embodiment, the PDCCH signaling is used to describe scheduling, transmission format, occupied frequency band resource, and the like of a channel resource, so that the terminal configures a receiving mode of the terminal according to the PDCCH signaling after receiving the PDCCH signaling, and the configured receiving mode can receive service data sent by the base station.

In addition, the base station may set the scheduling flag to "0" to identify that the base station transmits the service data on the resource of the continuous downlink subframe, and the like.

406: and the terminal receives a first MAC data packet sent by the base station, determines to receive service data on the resources of continuous downlink subframes according to a scheduling flag bit in a first MAC PDU subheader of the first MAC data packet, and configures the receiving mode of the terminal according to the PDCCH signaling.

407: and the base station transmits the service data to the terminal on the resource of the continuous downlink subframe scheduled by the first scheduling indication.

Specifically, when the base station sends the service data, the scheduling flag bit of the MAC pdu subheader of the MAC packet between the first MAC packet and the last MAC packet is the same as the scheduling flag bit of the first MAC pdu subheader.

Preferably, the method may further comprise: when transmitting service data to the terminal on the resource of the scheduled continuous downlink subframe, if the channel state changes, the base station updates the PDCCH signaling in the first scheduling indication according to the changed channel state, and transmits the updated scheduling update indication to the terminal. The specific process for generating the scheduling update indication is described in detail in 405, and is not described herein again.

408: and the terminal receives the service data sent by the base station on the resources of the continuous downlink subframes scheduled by the first scheduling indication.

Specifically, the terminal judges that the base station sends the service data on the resource of the continuous downlink subframe according to the scheduling flag bit in the MAC PDU subheader, and then receives the service data according to the receiving mode.

Correspondingly, the method may further include: and the terminal receives a scheduling updating instruction sent by the base station, performs configuration updating on the receiving mode of the terminal according to the scheduling updating instruction and receives service data according to the receiving mode after the configuration updating. And the terminal determines that the base station updates the resource of the scheduled continuous downlink subframe, performs configuration updating on the receiving mode of the terminal according to the PDCCH signaling in the scheduling updating indication, and receives service data according to the receiving mode after the configuration updating.

409: and when the service data is sent, the base station sets a scheduling flag bit in a second MAC PDU subheader of a second MAC data packet and sends the second MAC data packet to the terminal.

The last MAC packet of the service data transmitted by the base station is referred to as a second MAC packet in this embodiment. Specifically, in order to identify the completion of the service data transmission, the base station may further set a scheduling flag bit in a subheader of the second mac pdu, where the setting method is related to the setting method in 405. For example, the base station may set the scheduling flag bit to "1" to identify that the base station will end scheduling resources of consecutive downlink subframes for transmission of traffic data, and so on.

410: and the terminal receives a second MAC data packet, and receives the service data in the receiving mode according to the end of the scheduling flag bit in the second MAC PDU subheader of the second MAC data packet.
