The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for transmitting, receiving, and transmitting service data.
Background
Multicast Service (MBMS) is one of the important contents of 3GPP Service development. MBMS mainly refers to a network side simultaneously sending the same multimedia data to multiple receivers in the network, and compared with single-user transmission, MBMS greatly saves air interface resources.
In the prior art, there are two transmission modes of MBMS data: one is a multi-cell mode; one is single cell mode. When the MBMS data is transmitted in the single cell mode, an evolved node b (eNB) transmits the MBMS data in a semi-persistent scheduling manner, and schedules the MBMS data once in each semi-persistent scheduling period, that is, the eNB transmits the MBMS data through a Physical Downlink Shared CHannel (PDSCH), and indicates that the MBMS data is from a certain MBMS type through a Radio Network Temporary identity (Radio Network Temporary Identifier) on a Physical Downlink Control CHannel (PDCCH).
In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:
the eNB transmits the MBMS data in a semi-persistent scheduling manner, and therefore the eNB can only transmit the MBMS data once by using a fixed Transmission Time Interval (TTI) within a semi-persistent scheduling period, which cannot meet the requirement of MBMS data Transmission with a fast instantaneous rate, and may cause an increase in data delay and further cause data loss.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, embodiment 1 of the present invention provides a method for sending service data, including:
step 101: transmitting service data within the determined transmission time interval;
step 102: and informing the terminal of the transmission time interval of the subsequent data for transmitting the service in the current scheduling period.
In the embodiment of the invention, the base station can determine the transmission time interval for transmitting the service data in a scheduling period, so that the service data is transmitted more flexibly, the data transmission delay is reduced, and the data loss is avoided.
The following describes the above embodiment 1 in detail through embodiments 2 to 3 of the present invention, taking an MBMS service as an example.
This embodiment 2 may include the following steps:
step 201: the eNB determines a scheduling period; this step is an optional step.
Specifically, after determining to transmit a certain MBMS service data in the single cell mode, the eNB may determine a scheduling period for the MBMS service data, for example, automatically configure the scheduling period according to information such as QoS of the UE, or manually configure the scheduling period according to actual requirements. Further, the eNB may notify the UE of the determined length and the starting position of the scheduling period through a Multipoint Control Channel (MCCH).
Step 202: the eNB determines TTIs, e.g., 2 nd TTI and 6 th TTI, for transmitting MBMS data within a scheduling period.
It should be noted that, in this step, the eNB may use one or more TTIs in one scheduling period for transmitting the MBMS data, or may not transmit the MBMS data in the scheduling period.
Step 203: and the eNB sends the MBMS data in the 2 nd TTI, and informs the terminal that the TTI used for sending the subsequent data of the MBMS exists in the current scheduling period.
In this step, the eNB may send indication information in the 2 nd TTI, where the indication information indicates that a transmission time interval for sending subsequent data of the MBMS service exists in the current scheduling period. Specifically, the indication information may be carried in a physical downlink control channel message sent to the terminal or a media access control header of the multicast protocol data unit, for example, the indication information may occupy an extension bit or an extension field of the message or the media access control header. Taking the nth scheduling period shown in fig. 2 as an example, one scheduling period includes 8 TTIs, and Extend1 is indication information carried in a physical downlink control channel message, the eNB sends MBMS service data in the 2 nd TTI, and sets Extend1 sent in the 2 nd TTI to 1, which is used to indicate that there is a TTI for sending subsequent data of the MBMS service in the scheduling period.
Step 204: and the eNB sends the subsequent data of the MBMS in the 6 th TTI and informs the terminal that no TTI for sending the subsequent data of the MBMS exists in the current scheduling period.
Specifically, taking the nth scheduling period shown in fig. 2 as an example, the eNB sends the subsequent data of the MBMS service in the 6 th TTI, and sets an extended 1 sent in the 6 th TTI to 0, which is used to indicate that there is no TTI for sending the subsequent data of the MBMS service in the scheduling period.
In this embodiment, the indication information extended 1 may occupy only 1 bit, and occupy less resources.
Embodiment 3 of the present invention is similar to embodiment 2, except that the indication information in this embodiment is used to indicate the position of the TTI for transmitting the subsequent data of the MBMS service after the determined TTI.
Specifically, step 301-. In step 303 and 304 in this embodiment, the eNB sends the MBMS service data in the 2 nd TTI, and notifies the terminal that the TTI used for sending the subsequent data of the MBMS service is the 6 th TTI in the current scheduling period; and the eNB transmits the subsequent data of the MBMS in the 6 th TTI.
In this embodiment, the indication information extended 2 may be a sequence number value capable of directly indicating a TTI position, and a range that a value of the sequence number value can indicate is related to the number of TTIs in the scheduling period, for example, if the scheduling period includes 20 TTIs, the indication range of the indication information includes 0 to 19. For example 100 indicates the sequence number 5, i.e. the 6 th TTI, and for example 000 indicates the sequence number 0, i.e. the 1 st TTI. Taking the nth scheduling period shown in fig. 3 as an example, one scheduling period includes 8 TTIs, the indication information extended 2 carried by the physical downlink control channel message occupies 3 bits, the eNB sets the extended 2 sent in the 2 nd TTI to 101, which is used to indicate that the TTI for sending the subsequent data of the MBMS service is the 6 th TTI of the current scheduling period; the eNB also sets extended 2 sent in the 6 th TTI to null or the physical downlink control channel message sent in this TTI carries no indication information.
In this embodiment, the value of extended 2 and the TTI position may form an indication list. For example, extended 2 in the table is 1, corresponding to the 4 th TTI in the current scheduling period; extended 2 is 2, corresponding to the 6 th TTI in the current scheduling period. The indication lists can be stored by the eNB and the UE respectively, and also can be stored by other network entities and provide query for the eNB and the UE; the indication list may include a corresponding relationship between all TTI positions and extended 2 values in a scheduling period, or may only include a corresponding relationship between TTI positions that may be used for sending MBMS service data and extended 2 values, which are agreed by the eNB and the UE, so as to reduce bits occupied by the indication information and avoid unnecessary resource waste.
In this embodiment, the value of extended 2 and the TTI position may also form a location interval list. For example, extended 2 in the table is 1, the corresponding location interval parameter is 4, which indicates that the difference between the TTI of the subsequent data of the service and the TTI of the current TTI is 4, and if the current TTI is 2 nd TTI, the TTI of the subsequent data of the service is 6 th TTI.
Further, the value of extended 2 in this step may also include a case that indicates that there is no TTI for sending subsequent data, for example, extended 2 is null or a certain agreed value, and corresponds to that there is no TTI for sending subsequent data in the current scheduling period.
In this embodiment, the eNB may accurately indicate the TTI position for transmitting the MBMS subsequent data through the indication information, so that the UE can determine when to read the data conveniently, thereby saving terminal energy consumption.
In the embodiment of the method for sending the service data, the eNB schedules the transmission service data through the indication information, and can send a plurality of MBMS data in one scheduling period, so that the problem that the eNB can schedule the service data only once in one scheduling period in a single cell transmission mode in the prior art is solved, the transmission of the service data is more flexible, and the system performance meets the transmission burst requirement of the MBMS service data.
As shown in fig. 4, embodiment 4 of the present invention provides a method for receiving service data, which may include the following steps:
step 401: receiving service data;
step 402: and when the base station is informed to send the subsequent data of the service in the current scheduling period, the subsequent data of the service is received.
In the embodiment of the invention, the UE can acquire the TTI information of the received service data in time, so that the UE monitoring time is shortened, and the energy consumption of the terminal is further saved.
The above-mentioned example 4 is described in detail by the present invention of examples 5 to 6 below.
Assuming that the eNB as exemplified in embodiment 2 sends MBMS service data and indication information in the 2 nd TTI and the 6 th TTI in a certain scheduling period, embodiment 5 of the present invention may include the following steps:
step 501: the UE receives the length and the starting position of a scheduling period sent by an eNB through a Multipoint Control Channel (MCCH). This step is an optional step.
Step 502: and the UE receives the MBMS data in the 2 nd TTI in the current scheduling period.
Step 503: and the UE learns that the base station sends the subsequent data of the MBMS in the current scheduling period by reading the indication information.
Specifically, the UE may receive a physical downlink control channel message of the 2 nd TTI in the current scheduling period or a media access control header of a multicast protocol data unit, and read the indication information extended 1 therein, and if the indication information is 1, the UE knows that the base station will also send subsequent data of the MBMS service in the current scheduling period.
Step 504: and the UE reads the subsequent data of the MBMS service.
Specifically, after knowing the subsequent data of the MBMS service that is still sent by the base station in the current scheduling period, the UE may monitor the TTI after the 2 nd TTI until the subsequent data of the MBMS service is received in the 6 th TTI in the current scheduling period.
Step 505: the UE learns that the base station does not send the subsequent data of the MBMS service in the current scheduling period by reading the indication information, and the UE may not monitor the subsequent TTI in the current scheduling period.
Specifically, the UE may read the indication information extended 1 included in the physical downlink control channel message of the 6 th TTI, and if the indication information is 0, the UE knows that there is no TTI for sending the subsequent data of the MBMS service in the current scheduling period, and the UE may stop monitoring until the next scheduling period.
In this embodiment, the UE may stop monitoring the subsequent TTI in the current scheduling period when it is known that the TTI for transmitting the subsequent data of the MBMS service does not exist in the current scheduling period, so as to shorten UE monitoring time and further save terminal energy consumption.
Embodiment 6 of the present invention is similar to embodiment 5, except that the UE receives the subsequent service data according to the known TTI position where the base station transmits the subsequent service data in the current scheduling period. In this embodiment, it is assumed that the eNB in embodiment 3 transmits MBMS service data and indication information in the 2 nd TTI and the 6 th TTI in a certain scheduling period.
Specifically, steps 601-602 of this embodiment are similar to 501-502 of embodiment 5, and are not described again. Step 603-605 of this embodiment may be specifically as follows:
step 603: and the UE acquires the TTI position of the subsequent data of the MBMS service sent by the base station in the current scheduling period by reading the indication information.
Specifically, the UE may receive a physical downlink control channel message of the 2 nd TTI in the current scheduling period or a media access control header of a multicast protocol data unit, and read the indication information extended 2 therein. The UE may interpret extended 2 according to the indication information agreed with the eNB. For example, extended 2 directly indicates the sequence number value of the TTI location, and assuming that the extended 2 is 11, the UE knows that the base station has sent the subsequent data of the MBMS service in the 4 th TTI in the current scheduling period. For another example, the UE may obtain the TTI location in an indication list stored or capable of being queried by itself according to the value of extended 2. Assuming that the content of the indication list includes extended 2 as 1, corresponding to the 4 th TTI in the current scheduling period; extended 2 is 2, corresponding to the 6 th TTI in the current scheduling period. It is assumed that the UE receives the extended 2 being 2, and knows that the subsequent data of the MBMS service exists in the 6 th TTI in the current scheduling period through the list. For another example, the UE may obtain the location interval parameter for calculating the TTI location from a location interval list stored in the UE or capable of being queried according to the value of extended 2. Assuming that the content of the location interval list includes an extended 2 value of 1, and the corresponding location interval parameter is 3; the extended 2 value is 2, and the corresponding position interval parameter is 4; assuming that the extended 2 received by the UE takes the value of 2, the UE knows that the TTI of sending the subsequent data of the service in the current scheduling period is the 6 th TTI.
Step 604: and the UE reads the subsequent data of the MBMS service.
Specifically, the UE may select not to monitor or partially monitor the MBMS service in the 3 rd to 5 th TTIs, and monitor and receive subsequent data of the MBMS service in the 6 th TTI, thereby reducing the time for monitoring the UE and reducing energy consumption.
Step 605: the UE learns that the base station does not send the subsequent data of the MBMS service in the current scheduling period by reading the indication information, and the UE may not monitor the subsequent TTI in the current scheduling period.
Specifically, the physical downlink control channel message or the mac header of the multicast/multicast protocol data unit received by the UE in the 6 th TTI does not include the indication information, or the indication information is null, so that it is known that there is no TTI for transmitting subsequent data in the current scheduling period, and the UE may not monitor the subsequent TTI in the current period.
In this embodiment, the indication list and/or the location interval list stored by the UE are the same as the corresponding list stored by the eNB, may be determined by both the eNB and the UE through negotiation or protocol specification, or may be provided to the UE by the eNB; the above list may also be stored by other network entities and provide queries for the UE and/or eNB. Furthermore, if the TTI location determined by the UE according to the above list is outside the current scheduling period, the UE may regard the indication information as invalid without operating according to the indication information.
In the embodiment of the invention, the UE acquires the position for reading the MBMS data according to the indication information, thereby saving energy consumption.
It should be noted that, the methods for the eNB to set the indication information in the foregoing embodiments 2 and 3 may be combined, for example, the method provided in embodiment 2 determines the meaning of a part of the indication information, and the method provided in embodiment 2 determines the meaning of another part of the indication information, and the eNB may also use the methods for the eNB to set the indication information in the foregoing embodiments at the same time, for example, an extended field or a message to notify the UE of how to interpret the indication information preferentially. Similarly, the methods for the UE to read the indication information in the foregoing embodiments 5 and 6 may also be combined or used simultaneously, and are not described again. In addition, a method for receiving service subsequent data after the UE determines the TTI position according to the read indication information can be combined with a method for receiving MBMS service data at the TTI position appointed by the eNB in the prior art, and the UE can select when to read the indication information and receive the MBMS service data according to the indication information and directly receive the MBMS service data at the appointed TTI position.
It should be noted that, in the embodiment of the present invention, the determination of the scheduling period by the eNB and the reception of the scheduling period by the UE are optional steps. Specifically, the eNB may determine a scheduling period and notify the UE when establishing a connection with the UE or starting transmission, where whether the scheduling period changes has no necessary relation with whether and how the eNB and the UE transmit the service data in the embodiment of the present invention. In addition, in the embodiment of the present invention, before the eNB sends the service data in a certain scheduling period, the eNB may determine a TTI used for sending the MBMS data in the scheduling period, and apply the determined result to a certain period of time, for example, the determined TTI is used to send the MBMS data in n scheduling periods, where a smaller value of n is, the more the requirement for burstiness of service data transmission can be better satisfied by applying the embodiment of the present invention. For example, preferably, when n is 1, the eNB performs the step of determining the TTI for transmitting the MBMS data in each scheduling period before transmitting the service data in the scheduling period, so that the eNB can flexibly perform service data transmission.
In the above embodiment, the terminal can obtain the TTI information of the received service data in time, so that the terminal monitoring time is shortened, and the terminal energy consumption is further saved.

In the embodiment of the invention, the base station can determine the transmission time interval for transmitting the service data in a scheduling period, so that the service data is transmitted more flexibly, the data transmission delay is reduced, and the data loss is avoided.

In the embodiment of the invention, the terminal can acquire the TTI information of the received service data in time, so that the terminal monitoring time is shortened, and the energy consumption of the terminal is further saved.
