Description

Method for transmitting scheduling information, base station and user equipment

The present application relates to the field of communications technologies, and in particular, to a method for transmitting scheduling information, a base station, and a user equipment. Background technique

With the rapid development of the Internet, a large number of multimedia services have emerged, some of which enable multiple users to simultaneously receive the same data, such as video on demand, television broadcasting, video conferencing, online education, interactive games, and the like. In the field of mobile communications, people's needs are no longer satisfied with pure telephony and messaging services. However, current IP (Internet Protocol) protocols are not suitable for mobile networks because mobile networks have specific network structures, functional entities, and unique wireless interface bearers. These are all wired. IP networks are different, so existing IP multicast technologies cannot allow multiple mobile users to share mobile network resources. Therefore, 3G mobile operators represented by Hutchison 3G actively seek a new service mode that can broadcast multimedia information, and the service should be able to use relatively few system resources without affecting the operation of traditional mobile services.

In order to achieve the most efficient use of mobile network resources, the Global Standards Organization 3GPP (3rd Generation Partnership Project) proposes MBMS (Multimedia Broadcast I Multicast Service; Multicast and Broadcast Service). MBMS refers to a point-to-multipoint service in which a data source sends data to multiple users, and realizes network resource sharing, including core network and access network resource sharing, especially air interface resources. MBMS defined by 3GPP can not only realize plain text low-rate message class multicast and broadcast, but also realize high-speed multimedia service multicast and broadcast, which undoubtedly conforms to the trend of future mobile data development.

For LTE (Long Term Evolution) MBMS system spectrum usage is divided into the following two cases: One is that the MBMS system monopolizes one carrier frequency, called the dedicated carrier MBMS (DC-MBMS); the other is MBMS and Unicast (Unicast) The system shares a carrier called the hybrid carrier MBMS (MC-MBMS). In hybrid carrier MBMS, wireless resources for MBMS The source and the radio resources used for unicast are time-division, that is, some subframes of certain frames are divided and used exclusively for transmission of MBMS, and the configuration information of these subframes is included in the system information and broadcast to the UE ( User equipment).

The cell that uses the dedicated carrier for MBMS transmission is hereinafter referred to as a dedicated carrier MBMS cell; in contrast, a normal LTE cell is called a unicast cell, and an MBMS in a unicast cell is a hybrid carrier MBMS. The information that may be transmitted includes: scheduling information of downlink data transmission, scheduling information of uplink data transmission, uplink power control command, random access dedicated resource designation, MCCH (multicast control channel) information change indication, and the like.

A subframe in which scheduling information is configured is referred to as a PDCCH subframe. In the LTE FDD (Frequency Division Duplexing) system, the PDCCH subframe is all subframes. In the TDD (Time Division Duplexing) system, the PDCCH subframe is a downlink subframe and a subframe including a downlink time slot.

In the MBMS of the hybrid carrier, the subframe for transmitting the MBMS data and the control information is called an MBSF subframe. MBSF subframes are PDCCH indications that are not related to MBMS data scheduling, because the scheduling information of MBMS data on these subframes includes time domain, frequency domain location, MCS (Modulation and Coding Scheme), etc. are static, It does not change dynamically and can be included in the system information and MCCH information uniformly, so no dynamic indication is needed. The sub-frames used for transmitting MBMS data are not used for other services, including user data of unicast services, system information transmission, and paging. Therefore, these sub-frames do not have scheduling information for scheduling downlinks. .

For the dedicated carrier MBMS cell, there is no technical party that transmits scheduling information in the prior art.

Embodiment 1

This embodiment provides a method for transmitting scheduling information. Referring to FIG. 1, a flowchart of a method for transmitting scheduling information in the embodiment includes:

Step 101: The base station determines the location of the subframe used to carry the scheduling information, and the scheduling information is used to schedule the N types of data sent by the base station to the user equipment, where N is a positive integer; the location of the subframe used to carry the scheduling information meets the bearer. a subframe position requirement of scheduling information of at least one type of data, and N types including at least one type; Step 102: The base station sends scheduling information of N types of data on a subframe for carrying scheduling information.

Optionally, before performing step 101, the base station further determines a subframe position requirement of scheduling information of the N types of data. The N types of data include the following four types of data, but are not limited to the following: paging, dynamic scheduling system information, system information change indication, and MCCH change indication. In actual applications, N types of data include other The data indicated by the PDCCH, that is, the data that needs to transmit the scheduling information, is required. Further, in the embodiment of the present application, the N types of data may include only one of the above data, or may be a combination including any of the above data types.

In addition, the subframe position requirement of the scheduling information of the N types of data is determined. Specifically, if the data is periodically scheduled, the scheduling period may be different for different data, so the scheduling period of the scheduling information may be different. Therefore, the step may specifically be a transmission period of a subframe that determines scheduling information of N types of data.

In an actual application, the subframe that carries the scheduling information in the embodiment of the present application may be a PDCCH subframe or an ePDCCH (Enhanced Physical Downlink Control Channel) subframe.

Next, step 101 is performed, that is, the base station determines a location of the subframe used to carry the scheduling information, where the location of the subframe for carrying the scheduling information meets scheduling information of at least one type of data of the N types of data. Subframe position requirements. Wherein, if it is for a professional carrier MBMS cell, step 101 specifically determines a location of a subframe used to carry scheduling information in a dedicated carrier MBMS cell; when the method is used in other cases, it is determined to be used in other cases. The location of the subframe carrying the scheduling information.

First, how to determine the location of the subframe used to carry the scheduling information, in a possible embodiment, the step 101 specifically includes: determining, by the base station, the location of the subframe used to carry the scheduling information according to the data type of the N types of data. .

As a specific example, assuming that N types of data are paging, dynamically scheduled system information, system information change indication, and MCCH change indication, the base station determines the subframe position of the paging scheduling information as the bearer scheduling information. The position of the sub-frame, because the position of the sub-frame where the page is located is solid The qualitative is higher, followed by the fixed position of the subframe position where the dynamically scheduled system information is located, and then the fixedness of the subframe position where the MCCH change indication is located, and finally the subframe position where the system information change indication is located. The fixability is the lowest, because the more fixed the subframe position of the data, the more difficult it is to change, and it may need to involve modification of multiple parameters and modification of existing protocols, so the subframe position of the data according to the fixed position of the subframe is highly fixed. To determine the location of the subframe used to carry the scheduling information, the modification of the existing parameters, protocols, and the like can be reduced, so that the operation is single.

In an actual implementation, the priority may be set on the base station side, and the subframe for carrying the scheduling information is determined by determining the priority, for example, setting priority for each type of data, and continuing to use the above four types of data as an example to set the search. The priority of the call is higher than the priority of the dynamically scheduled system information, and the priority of the dynamically scheduled system information is higher than the priority of the MCCH change indication, and the priority of the MCCH change indication is higher than the priority of the system information change indication. Then, the step 101 specifically includes: determining a priority level of the N types of data; determining, by using the scheduling information of the data with the highest priority, the subframe in which the scheduling information is used.

Certainly, in actual operation, the determining condition may be directly set on the base station side according to the fixedness of the subframe position where the data is located. For example, step 101 specifically includes: determining whether the N types of data include paging, and if the paging is included, Then, determining that the subframe in which the scheduling information of the paging is located is a subframe for carrying scheduling information; if the paging is not included, determining whether the N types of data include dynamically scheduled system information, and if the dynamically scheduled system information is included, Determining the subframe in which the scheduling information of the dynamically scheduled system information is located is a subframe for carrying scheduling information; if the system information of the dynamic scheduling is not included, then continuing to judge until the last data is determined, and then determining this The subframe in which the scheduling information of the last data is located is a subframe for carrying scheduling information.

Certainly, in actual application, the location of the subframe used to carry the scheduling information may be determined by other methods, for example, the subframe in which the scheduling information of one type of data is randomly determined is a subframe for carrying scheduling information, for example, When the N types of data include paging, the base station may determine that the subframe in which the scheduling information of the paging is located is a subframe for carrying scheduling information; and, for example, when the N types of data include dynamically scheduled system information, the base station The subframe in which the scheduling information of the dynamically scheduled system information is located may be a subframe for carrying scheduling information; for example, when N types of data are included When the MCCH changes the indication, the base station may determine that the subframe in which the scheduling information of the MCCH change indication is located is a subframe for carrying scheduling information. When the above three types of data are included, one may be randomly determined, or may be determined according to several rules described above, for example, the fixedness of the subframe position where the data is located, such as priority.

Next, the sub-frame for carrying the scheduling information determined in step 101 needs to satisfy the meaning of the subframe position requirement of the scheduling information of the data of at least one type of N types of data.

On one hand, as described above, the scheduling period may be different for different data, so the location of the subframe used to carry the scheduling information determined in step 101 needs to satisfy at least one of the N types of data. The scheduling period of the scheduling information of the data.

On the other hand, the meaning of the subframe position requirement for the scheduling information of at least one type of data has different meanings according to different situations, and is exemplified below.

The first possible case: for example, N types of data are specifically four types, such as the paging, dynamic scheduling system information, system information change indication, and MCCH change indication, as described above, and scheduling of the four types of data. The scheduling period of information varies. In one case, the determined scheduling period of the subframe for carrying the scheduling information needs to be satisfied, regardless of the determined subframe in which the subframe for carrying the scheduling information is specifically the scheduling information of which of the four types of data. A scheduling period of the scheduling information of the four types of data, for example, determining that the subframe in which the scheduling information of the paging is located is a subframe for carrying scheduling information, and the scheduling period of the subframe used for carrying the scheduling information may be The scheduling period of the scheduling information is the same, and may also be the same as the scheduling period of the scheduling information of the dynamically scheduled system information. In another case, the determined subframe for carrying the scheduling information is specifically the subframe in which the scheduling information of the data of the four types of data is located, and the determined scheduling period of the subframe for carrying the scheduling information satisfies the The scheduling period of the scheduling information of the data in the four types of data, for example, the subframe in which the scheduling information of the paging is determined is the subframe used to carry the scheduling information, and the scheduling period of the subframe used to carry the scheduling information and the paging The scheduling period of the scheduling information is the same. Therefore, the above is the case of at least one of them.

The second possible case: If two of the scheduling periods of the scheduling information of the four types of data are the same, for example, the scheduling period of the scheduling information of the paging and dynamically scheduled system information is the same. a love The scheduling period of the subframe for carrying the scheduling information needs to satisfy the four types of subframes, where the subframe for carrying the scheduling information is specifically the subframe in which the scheduling information of the data is located. A scheduling period of the scheduling information of the data, for example, determining that the subframe in which the scheduling information of the paging is located is a subframe for carrying scheduling information, and the scheduling period of the subframe used for carrying the scheduling information and the scheduling of the paging The scheduling period of the information is the same, and may be the same as the scheduling period of the scheduling information of the dynamically scheduled system information, regardless of which of the two, because the scheduling periods of the scheduling information of the two types of data are the same, so that at least two are satisfied. The subframe position requirement of the scheduling information of the data. In another case, the determined subframe for carrying the scheduling information is specifically the subframe in which the scheduling information of the data of the four types of data is located, and the determined scheduling period of the subframe for carrying the scheduling information satisfies the The scheduling period of the scheduling information of the data in the four types of data, for example, the subframe in which the scheduling information of the paging is determined is the subframe used to carry the scheduling information, and the scheduling period of the subframe used to carry the scheduling information and the paging The scheduling period of the scheduling information is the same, but the scheduling periods of the scheduling information of the two types of data are the same, so that is the subframe position requirement that satisfies the scheduling information of at least two types of data.

In a third possible case, there are two subframes for carrying the scheduling information determined in step 101, for example, the subframe in which the scheduling information of the paging is located and the subframe in which the scheduling information of the dynamically scheduled system information is located The subframe is determined to be used to carry the scheduling information, and then the location of the subframe for carrying the scheduling information satisfies the scheduling information of the at least two types of data according to the first possible situation or the second possible case. Subframe position requirements.

Next, the base station performs step 102 of transmitting scheduling information of N types of data on the subframe for carrying the scheduling information.

Specifically, if only one subframe is determined for carrying the scheduling information, the scheduling information of the N types of data is sent on the one subframe for carrying the scheduling information. If the determined subframes for carrying the scheduling information are two or more, the step 102 may be specifically: scheduling the N types of data according to a predetermined rule in the corresponding information for carrying the scheduling information. Sent on the subframe. The predetermined rule may be determined according to a scheduling period. For example, scheduling information with a similar scheduling period is sent on the same subframe used for carrying scheduling information. In its In other embodiments, the predetermined rule may also be other rules, for example, the scheduling information of the dynamically scheduled system information and the MCCH change indication need to be sent in the same subframe for carrying the scheduling information.

Next, the user equipment side is convenient to determine the location of the subframe used to carry the scheduling information, and the base station side further sends a parameter to the user equipment UE, so that the UE can determine the location of the subframe used to carry the scheduling information based on the parameter. In an actual application, the base station may send the parameter to the UE in the system information of the dedicated carrier MBMS cell fixed scheduling, or may send the parameter to the system information of the unicast cell covered by the dedicated carrier MBMS cell. The UE may also be sent to the UE in the system information of other unicast cells, for example, the system information of the dedicated carrier multicast and the neighbor unicast cell of the MBMS cell of the broadcast service. Of course, it may be sent to the UE by other means, which is not specifically limited in this application. The system information of the dedicated carrier MBMS cell can be divided into two types, fixed scheduling system information and dynamically scheduled system information. The fixed scheduled system information does not need the PDCCH indication, so it can be used to carry information such as the parameters of the subframe used to determine the bearer scheduling information and the frequency domain location of the subframe used to carry the scheduling information. The unicast cell that covers the same geographical area as the professional carrier MBMS cell completely covers or partially overlaps the coverage; the neighbor unicast cell of the professional carrier MBMS cell refers to the professional carrier. A unicast cell adjacent to the MBMS cell.

The method flow shown in FIG. 1 is described from the base station side. Referring to FIG. 2 again, a flowchart of a method for transmitting scheduling information in the user equipment on the user equipment side is shown in FIG. 2 . , the method includes:

Step 201: The UE determines the location of the subframe that carries the scheduling information, and the scheduling information is used to schedule the N types of data that the base station sends to the UE, and the location of the subframe that carries the scheduling information meets the scheduling that carries at least one type of data. The subframe position of the information requires that N types include at least one type, and N is a positive integer;

Step 202: The UE acquires scheduling information for scheduling N types of data at a location of the subframe that carries the scheduling information.

Optionally, the UE further receives the parameter sent by the base station before performing step 201. Similarly, the UE may obtain the parameter from the fixed-carrier information of the dedicated carrier multicast and the broadcast service MBMS cell. Or obtaining parameters from system information of a unicast cell covered with a dedicated carrier multicast and broadcast service MBMS cell; or obtaining parameters from system information of a dedicated carrier multicast and a neighbor unicast cell of a broadcast service MBMS cell.

The UE then performs step 201 to determine the location of the subframe carrying the scheduling information. In a possible implementation, the location of the subframe carrying the scheduling information may be determined based on the foregoing parameters. In practical applications, when the parameter is a parameter of a subframe position for acquiring scheduling information of a paging, a parameter of a subframe position of scheduling information of dynamically scheduled system information, and/or scheduling information of an MCCH change indication, respectively. In the step 201, the UE determines the location of the subframe carrying the scheduling information based on the parameter, where the UE determines, according to the parameter, the subframe carrying the scheduling information as the scheduling information of the paging. The subframe, the subframe in which the scheduling information of the dynamically scheduled system information is located, and/or the subframe in which the scheduling information indicated by the MCCH change is located.

Certainly, in actual operation, a fixed rule may be negotiated between the base station and the UE in advance. For example, the base station sends scheduling information of N kinds of data in a subframe in which the scheduling information of the paging is located, so that the UE side only needs to pass the parameter. The location of the subframe in which the scheduling information of the paging is located can determine the location of the subframe carrying the scheduling information, which can reduce the calculation amount of the UE, save resources and save power, and improve processing speed.

Therefore, the step 201 may specifically be: determining, according to the parameter and the predetermined rule, a location of the subframe carrying the scheduling information. In this case, when the rule changes, the base station may send the indication information of the subframe position change for carrying the scheduling information to the UE, so that the UE can know in time what parameters need to be acquired, and then determine the child that carries the scheduling information. The position of the frame.

After determining the location of the subframe carrying the scheduling information in step 201, the UE performs step 202, that is, acquiring scheduling information for scheduling N types of data at the location of the subframe carrying the scheduling information; The UE receives each subframe, resulting in waste of resources.

Optionally, the UE may obtain the frequency domain location information of the subframe that carries the scheduling information, because the UE acquires the scheduling information, and needs to determine the time domain location information of the subframe carrying the scheduling information and the frequency domain location information, which is described in the foregoing. How to determine the location information in the time domain, so the frequency domain location information of the subframe carrying the scheduling information can also be obtained here, so that the step 202 can be performed quickly. The frequency domain location information may be obtained simultaneously with the foregoing parameters, or may be separately obtained, and the obtained path is similar to the acquisition path of the foregoing parameters.

Optionally, the step 102 may be: the UE parses the subframe with the bearer scheduling information, and obtains scheduling information of the N types of data.

In a specific application, the scheduling information used to indicate the scheduling information of the UE's own data (including the uplink data and the downlink data) is scrambled by using the C-RNTI, that is, when the UE detects the scheduling information, the C-RNTI is used to match, if The coincidence indicates that the scheduling information is sent to itself, and the C-RNTI is unique to each UE.

The scheduling information used to indicate system information scheduling is scrambled using SI-RNTI. The SI-RNTI is a fixed value and is shared by all UEs.

The paging scheduling information is scrambled using P-RNTI, and the P-RNTI is a fixed value, which is shared by all UEs. The scheduling information of the MCCH change indication is scrambled using M-RNTI, and the M-RNTI is a fixed value, which is shared by all UEs.

Therefore, in step 202, the UE may perform matching by using C-RNTI, SI-RNTI, P-RNTI, and M-RNTI respectively. If the matching is successful, it indicates that the subframe carrying the scheduling information carries the corresponding data. The scheduling information is obtained, and then the UE can further perform operations such as receiving or transmitting data according to the scheduling information.

As can be seen from the above description, in the embodiment of the present application, a scheduling information transmission method that can be applied to a dedicated carrier MBMS cell is provided. Further, in the embodiment of the present application, the base station determines a subframe used to carry scheduling information. a location, a subframe position requirement for the scheduling information of the at least one type of data that is used to carry the scheduling information, and then scheduling information of each type of data is configured to be sent on the subframe, that is, one PDCCH. The frame may include scheduling information of multiple types of data, so the scheduling information is not required to be configured in each downlink subframe, so the resources of the dedicated carrier MBMS cell can be sufficiently used for broadcasting MBMS data, and the PDCCH resources are fully utilized. Therefore, by using the method in this embodiment, the utilization rate of the radio resources is improved, and the technical effect of saving the radio resources is realized.
