Description

Signal transmission method and device

Technical field

The present invention relates to the field of communications technologies, and in particular, to a signal transmission method and apparatus. Background technique

Currently, the downlink data transmission service provided by the wireless communication system to the user equipment (UE, User Equipment) mainly includes a unicast service and a Multimedia Broadcast Multicast Service (MBMS), wherein the unicast service is directed to the UE and the The inter-point communication between the base stations, and the MBMS service is directed to the case where multiple UEs simultaneously receive the same service.

The foregoing MBMS service is provided by the MBMS area. Specifically, a plurality of cells in the network form an MBMS area, and each cell in the MBMS area transmits an MBMS service belonging to the MBMS area; the number of cells included in the current MBMS area And the service content provided is pre-semi-statically planned, that is, the number of cells included in each MBMS area and the service content provided are generally fixed.

For a UE that is in a certain cell, the UE in the Radio Resource Control (RRC) connection state can receive the unicast service or the MBMS service, and the UE in the idle state can receive the MBMS service. However, the unicast service cannot be received, that is, the UE in the idle state needs to initiate random access, and after receiving the cell successfully, can receive the unicast service provided by the serving cell;

Currently, when the UE needs to order a certain video program, the unicast mode needs to be adopted. In this case, if the UE in the idle state that is receiving the MBMS service needs to order a certain program, it needs to firstly go to the network side. Initiating random access; as the number of UEs continues to increase, multiple idle UEs may need to order the same service in the same time period, that is, multiple idle UEs will be based on the same during the same time period. The service request frequently initiates a random access request to the network side, which is highly likely to cause access congestion and affect the access of UEs with other unicast service requirements.

There are three cases of B alone. In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship.

As shown in FIG. 1 , a flowchart of a signal transmission method according to an embodiment of the present invention includes the following steps:

S101: The UE determines, according to the correspondence between the configuration information of the first uplink signal and the service item supported by the current MBMS cell, the configuration information of the first uplink signal when the UE requests the service item, where the service is The project includes: a business, or a business collection containing at least two services, or a business system supporting at least one business;

S102: The UE sends the first uplink signal according to the configuration information of the first uplink signal.

In the embodiment of the present invention, the configuration information of the first uplink signal has a corresponding relationship with the service item supported by the cell, and the corresponding relationship is consistent between the UE and the network side, and the UE determines, according to the correspondence, the current service item that needs to be requested. The configuration information is sent according to the determined configuration information, and the first uplink signal is sent according to the determined configuration information. In a specific implementation process, any one of the service items may correspond to one or more types of configuration information. When the service item corresponds to multiple configuration information, the UE may select Any one of the configuration information, sending the first uplink signal; correspondingly, the network side is configured according to the configuration information of the first uplink signal, The first uplink signal is detected. After detecting the first uplink signal, the service item requested by the UE is determined according to the configuration information of the detected first uplink signal, and then the network side provides the determined service item for the UE. With the embodiment of the present invention, the UE can request the service item from the network side without initiating a random access request to the network side, thereby reducing the access signaling overhead of the network side, avoiding access congestion, and the uplink and downlink signal interference is deteriorated. .

In the specific implementation process, the corresponding relationship may be pre-defined by the network side and the UE. Specifically, the network side pre-configures the corresponding relationship, and notifies the configured correspondence to the UE, where the network side and the UE respectively store the corresponding relationship. The network side may also temporarily notify the UE through the system message; the foregoing pre-agreed manner may be combined with the manner of sending the system message, for example, the network side and the UE first pre-arrange the configuration information and the cell of the first uplink signal. The corresponding relationship of the service items that can be supported. Afterwards, the network side notifies the part of the configuration information supported by the current cell in the system message, and the part of the configuration information belongs to the pre-agreed information.

Optionally, the configuration information of the first uplink signal includes: at least one of a sequence used by the first uplink signal, a time resource that sends the sequence, and a frequency resource that sends the sequence; or ,

In a specific implementation process, the configuration information of the first uplink signal may include at least one of a sequence used by the first uplink signal, a time resource of the transmission sequence, and a frequency resource of the transmission sequence, where the sequence may be specifically m. Sequences or Zad-off Chu sequences, etc.; different service items may correspond to different sequences, or may correspond to different time resources, or may correspond to different frequency resources. The configuration information of the first uplink signal may further include at least one of a load quantity of a data packet used by the first uplink signal, a modulation and coding mode of the data packet, a time resource of the transmission data packet, and a frequency resource of the transmission data packet. Different service items may correspond to different load numbers, or may correspond to different modulation and coding modes, or may correspond to different time resources, and may also correspond to different frequency resources.

It should be noted that, in one configuration information, only the different business items can be distinguished. The configuration information may include configuration information that can distinguish different service items, and other configuration information that sends the first uplink signal. For example, the configuration information may specifically include only sequences that distinguish different service items, and different sequences correspond to each other. For the different service items, the configuration information may include or may not include a time-frequency resource of the transmission sequence. If the configuration information includes a time-frequency resource of the transmission sequence, the time-frequency resource is notified to the UE together with the sequence as configuration information. If the time-frequency resource of the transmission sequence is not included in the configuration information, the network side needs to separately notify the UE to send the time-frequency resource of the sequence. The specific notification mode is not limited. For example, the time-frequency resource may be pre-defined by the network side and the UE. It is also possible for the network side to notify the UE of the determined time-frequency resource bearer in the cell system message. Specifically, the frequency resource for transmitting the first uplink signal may be set as k resource blocks of the cell carrier center, where n is positive. Integer, you can set the time resource to a periodic time window, such as each radio frame Subframe 0 and 1 and the like.

In a specific implementation process, the UE may request a service, or may request a service set including multiple services, where the service set may be a type of service, such as a news service, or a combination of multiple services, and the UE may also Requesting a service system, the UE requests the service system to request access to the service system. In the existing mode, the UE access service system sends a random access request message directly to the network side, and the service type is diversified. In the future, the current cell is likely to be able to support multiple types of service systems at the same time, such as an MBMS system, a unicast service system, an inter-UE direct communication system, a machine type communication system, etc. In this case, the method of the embodiment of the present invention may be adopted, as needed. The configuration information corresponding to the requested service system sends the first uplink signal, and the network side can determine the service system that the UE needs to access according to the detected configuration information of the first uplink signal.

Optionally, in step S101, the service item is the one type of service or the service set; after the UE sends the first uplink signal, the method further includes:

In a specific implementation process, after the service or service set application in the MBMS system requested by the UE is successfully applied, the network side receives a response message, where the response message carries the area of the MBMS area of the service or service set requested by the UE. Identification, the area identifier is used to add 4 especially the MBMS area a reference signal of the domain, so that the UE performs channel estimation based on the reference signal, and receives the requested service or service set according to the result of the channel estimation; the preset time-frequency resource may be pre-agreed by the network side and the UE, or may be The network side is notified to the UE by using the cell system message. For example, the frequency resource in the preset time-frequency resource may be m resource blocks in the cell carrier center, and the time resource may be set as a periodic time window, where the time window may be For example, the time window may be separated from the time window in which the uplink signal is sent by N subframes or radio frames, etc. In the embodiment of the present invention, the UE is configured according to the service item. The configuration information is sent to the first uplink signal, and the network side may determine the service item required by the UE according to the configuration information of the detected first uplink signal, and the sequence, the number of loads, the modulation and coding mode, and the like that may be included in the configuration information may be for multiple UEs. Public, therefore, these UEs do not need to separately send random access request messages, thereby saving network side Accessing the signaling overhead to alleviate the network access congestion. In addition, the MBMS area in the embodiment of the present invention is dynamically allocated based on the requirements of the UE, and is different from the current semi-static or static MBMS area plan, as shown in FIG. 2 The dynamic MBMS area planning mode is provided in the embodiment of the present invention. In the dynamic MBMS area planning mode, the MBMS area can be temporarily allocated according to the on-demand requirement of the UE. When the UE's on-demand is completed, the temporary planning is released. The MBMS area can improve resource utilization efficiency.

Optionally, the service item is the one type of service; before the sending, by the UE, the first uplink signal according to the determined configuration information of the first uplink signal, the method further includes:

Determining, by the UE, the configuration information corresponding to the service set that needs to be requested according to the correspondence between the configuration information of the second uplink signal and the service set supported by the current MBMS cell; the service in the service set that needs to be requested currently includes the The service that the UE currently needs to request;

In the specific implementation process, in order to improve the on-demand efficiency of the UE and the cost of the network side, the UE may first send a second uplink signal to request the service set where the service is located, and then send the first uplink signal request service. After confirming the service set requested by the UE according to the detected second uplink signal, the network side may first record the service set requested by the UE, and after detecting the first uplink signal sent by the UE, from the previously confirmed service set, Looking for the first upstream signal The configuration information corresponds to the business.

Optionally, the configuration information of the second uplink signal includes: at least one of a sequence used by the second uplink signal, a time resource for sending the sequence, and a frequency resource for sending the sequence; or ,

The configuration information of the second uplink signal includes: a number of payloads of the data packet used by the second uplink signal, a modulation and coding manner of the data packet, a time resource for sending the data packet, and a frequency of transmitting the data packet. At least one of the four resources.

Here, similar to the foregoing first uplink signal, the configuration information of the second uplink signal in the embodiment of the present invention may also include a sequence, a time-frequency resource, and the like, and the corresponding relationship between the configuration information of the second uplink signal and the service set is The corresponding relationship between the configuration information of the first uplink signal and the service item is similar, and details are not described herein again.

Optionally, after the sending, by the UE, the second uplink signal, the method further includes:

In a specific implementation process, the UE may send the first uplink signal of the request service after sending the second uplink signal of the request service set, and the UE may also send the second uplink signal after confirming that the requested service set application is successful. And sending the first uplink signal of the request service. The resource bearer is sent to the UE in the cell system message. For example, the frequency resource in the preset time-frequency resource may be the n resource blocks in the carrier center, and the time resource may be a periodic time window. The time window in the time-frequency resource is associated with the sending time window of the first uplink signal. For example, the time window in the preset time-frequency resource may be set to be separated from the sending time window of the second uplink signal by M. Frame or radio frame, etc.

Optionally, the mapping between the configuration information of the first uplink signal and the service supported by the current MBMS cell includes: the at least two different services supported by the current MBMS cell are the same as those used by the first uplink signal. The sequence, the different services supported by the current MBMS cell are corresponding to different time resources for sending the sequence; the configuration information of the second uplink signal and the current MBMS The corresponding relationship of the service set supported by the cell includes: different service sets supported by the current MBMS cell corresponding to different sequences used by the second uplink signal, and different service sets supported by the current MBMS cell corresponding to the sequence The same time resource; or,

Optionally, the mapping between the configuration information of the first uplink signal and the service supported by the current MBMS cell includes: at least two different services supported by the current MBMS cell correspond to data packets used by the first uplink signal. The same number of payloads, the different services supported by the current MBMS cell correspond to different time resources for sending the data packet; the correspondence between the configuration information of the second uplink signal and the service set supported by the current MBMS cell includes: The different service sets supported by the cell correspond to the different load numbers of the data packets used by the second uplink signal, and the different service sets supported by the current MBMS cell correspond to the same time resources for sending the data packet; or

Optionally, the mapping between the configuration information of the first uplink signal and the service supported by the current MBMS cell includes: at least two different services supported by the current MBMS cell correspond to the first The same modulation and coding mode of the data packet used by the uplink signal, the correspondence between the information supported by the current MBMS cell and the service set supported by the current MBMS cell includes: the different service sets supported by the current MBMS cell correspond to the second The different modulation and coding modes of the data packets used by the uplink signal, the different service sets supported by the current MBMS cell are corresponding to the same time resource for sending the data packet; or

In a specific implementation process, different services or service sets may be distinguished by a sequence, a number of uplink data packets, a modulation and coding mode of an uplink data packet, and a time-frequency resource. Therefore, time resources corresponding to different service sets may be used. The same may be different. The time resources corresponding to different services may be the same or different. One achievable manner is to distinguish different services by using time resources, and to distinguish different service sets by other configuration information, and the other may be implemented. The way is to distinguish different service sets by time resources, and to distinguish different services by other configuration information. As shown in Figure 3 (a), different service sets share a transmission time window. Different service sets correspond to different sequences. Different services do not share the transmission time window. In this case, the sequences corresponding to different services may be the same or different; b), different service sets do not share the transmission time window, the sequences corresponding to different service sets may be the same or different, different services share the transmission time window, and different services correspond to different sequences;

In a specific implementation process, if different services correspond to the same time resource, other configuration information needs to be used to distinguish different services, for example, different sequences may be used to distinguish different services. If different service elements correspond to different time resources, the other configuration information corresponding to different services may be the same or different. For example, different services may be corresponding to different time resources, and at least two different services correspond to the same sequence. In this way, you can save the sequence type. Corresponding to the service, different service sets may correspond to different time resources, and may also correspond to the same time resource. When corresponding time resources are corresponding, other configuration information corresponding to different service sets may be the same or different.

Optionally, the service system includes any one or more of an MBMS system, a unicast service system, an inter-UE direct communication system, and a machine type communication system.

In the existing mode, the UE accesses the service system by directly sending a random access request message to the network side. With the diversification of service types, the current cell is likely to support multiple types of service systems at the same time, such as the MBMS system. The unicast service system, the inter-UE direct communication system, the machine type communication system, and the like. In this manner, the first uplink signal may be sent according to the configuration information corresponding to the service system that needs to be requested. That is, the service system that the UE needs to access may be determined according to the configured configuration information of the first uplink signal.

Optionally, the service item is the service system;

In a specific implementation process, if the UE accessing the service system is triggered by the UE itself, for example, the UE needs to send the uplink data packet to the network side, the UE may determine the service system that needs to be accessed by itself, and then according to the determined configuration of the service system. And transmitting, by the network, the first uplink signal, and determining, by the network side, the service system that the UE needs to access according to the configuration information of the first uplink signal, and then scheduling the UE to access the determined service system; if the UE accessing the service system is triggered by the network side For example, the network side needs to transmit a downlink data packet to the UE, and the UE is in an idle state, and the network side needs to instruct the UE to access the network. In this case, the network side may send the UE to the UE to access the network. The paging message, and the specific service system in the network that the UE needs to access is notified in the paging message, so that the UE can be prevented from randomly selecting a service system to access, and the network side needs to blindly check different service systems to discover the UE, which can reduce the overhead of the network side and improve the data transmission efficiency.

Corresponding to the method for performing signal transmission on the UE side, the embodiment of the present invention further provides a method for performing signal transmission on the network side. The method for performing signal transmission on the network side corresponds to the UE side, and the details are not repeated herein.

As shown in FIG. 4, a flowchart of a signal transmission method according to Embodiment 2 of the present invention includes: S401: A network side device detects, according to at least one configuration information of a first uplink signal, a first uplink signal sent by a user equipment UE;

S402: The network side device determines, according to the correspondence between the configuration information of the first uplink signal and the service item supported by the current MBMS cell, the service item corresponding to the detected configuration information of the first uplink signal, where the service item is The system includes: a service, or a service set that includes at least two services, or a service system that supports at least one service. The network side device in the embodiment of the present invention may be a base station that manages a cell, and the like.

Optionally, the service item is the one type of service or the service set;

The domain identifier, the at least one MBMS area is used to transmit the service item requested by the UE.

Optionally, before the network side device sends the area identifier that includes the at least one MBMS area, the method further includes:

The network side device determines that the received power of the detected first uplink signal is greater than a set threshold. In a specific implementation process, after determining that the received power of the detected first uplink signal is greater than a set threshold, the network side device may allocate an area identifier of the MBMS area to the UE in response to the service item request of the UE, and in the MBMS area.

Similar to the process of the UE on-demand a program, the UE needs to access the network first before feeding back the MBMS reception quality of the multicast broadcast service to the network side. When a large number of idle UEs frequently initiate random access to the network side, the UE will appear. The network side access signaling overhead increases, resulting in access congestion and deterioration of uplink and downlink interference. Based on this, the embodiment of the present invention further provides the following signal transmission method and apparatus.

As shown in FIG. 12, a flowchart of a method for performing signal transmission according to Embodiment 6 of the present invention includes:

S1201: The UE determines, according to the correspondence between the configuration information of the uplink signal and the MBMS receiving quality level, the at least one configuration information corresponding to the current actual receiving quality level. The current actual receiving quality level is the MBMS receiving of the MBMS region where the UE performs the location. The quality of reception received by the quality measurement;

S1202: The UE sends an uplink signal according to the determined configuration information, so that the network side device determines the actual reception quality level of the UE according to the configuration information of the received uplink signal.

In the embodiment of the present invention, the configuration information of the uplink signal has a corresponding relationship with the MBMS receiving quality level, and the corresponding relationship is consistent between the UE and the network side, and the UE determines the configuration information corresponding to the current actual receiving quality level according to the corresponding relationship. And sending an uplink signal according to the determined configuration information. In a specific implementation process, any one of the receiving quality levels may correspond to one or more configuration information. When the receiving quality level corresponds to multiple configuration information, the UE may select any one of the configurations. information, Correspondingly, the network side detects the uplink signal according to the configuration information of the uplink signal, and after detecting the uplink signal, determines the actual reception quality level of the UE according to the configuration information of the detected uplink signal. With the embodiment of the present invention, the UE can report the current actual reception quality level to the network side without initiating a random access request to the network side, thereby reducing the access signaling overhead of the network side, avoiding access congestion, and uplink and downlink signal interference. The problem of deterioration.

In the specific implementation process, the corresponding relationship may be previously agreed by the network side and the UE. Specifically, the network side may notify the UE after the corresponding relationship is configured, and the network side and the UE respectively store the corresponding relationship. The network side temporarily notifies the UE through the system message; the foregoing pre-agreed manner is combined with the manner of sending the system message. For example, the network side and the UE first pre-arrange the correspondence between the configuration information of the uplink signal and the receiving quality level. Then, the network side notifies the part of the configuration information supported by the current cell in the system message, where the part of the configuration information belongs to the pre-agreed configuration information. In a specific implementation, the UE may perform channel estimation based on the cell-specific reference signal, and according to The result of the channel estimation receives the cell system message;

In a specific implementation process, when the UE needs to obtain the foregoing correspondence by using the system message, or obtain the foregoing partial configuration information, the UE first detects the synchronization signal of the current cell, synchronizes with the cell, and then receives the broadcast channel of the current cell to obtain the broadcast. a system message in the channel, the system message may indicate a service system that the current cell can provide, such as an MBMS system, or a broadcast service sent by one UE to other multiple UEs (which may also be considered as a similar MBMS system), and thereafter, The UE reads the system message to obtain the foregoing correspondence or the partial configuration information. The foregoing correspondence may be predefined, that is, it is not required to be acquired from the network side, but is stored in advance on the UE side. . Similarly, the above multiple reception quality levels may also be predefined or acquired from the network side.

The receiving quality level may be excellent, good, general, poor, etc., or specific values, which may be represented by an index, for example, index 0 corresponds to one modulation and coding mode, and index 1 corresponds to another modulation and coding mode. Etc. Here, the reception quality may be represented by one or a combination of different modulation and coding modes, received power, signal interference and noise ratio of the received signal, channel state indication, etc., and different reception quality levels may be separately set, respectively Corresponding to different receiving qualities Quantity situation.

Optionally, the configuration information of the uplink signal includes: at least one of a sequence used by the uplink signal, a time resource for sending the sequence, and a frequency resource for sending the sequence; or

The configuration information of the uplink signal includes: a number of payloads of the data packet used by the uplink signal, a modulation and coding manner of the data packet, a time resource for transmitting the data packet, and a frequency resource for transmitting the data packet. At least one of them.

Here, the configuration information of the foregoing uplink signal is cell-specific or MBSF-region-specific, rather than UE-specific, that is, multiple UEs have multiple UEs or one MBSFN region within one cell if the received reception quality level is the same. The multiple UEs use the same configuration information to send the uplink signal to the network side. Therefore, when the UE in the idle state reports the reception quality level, it does not need to access the network side through the UE-specific signal. Signaling overhead and resource overhead. For example, the network side can detect uplink signals sent by different UEs on different time-frequency resources corresponding to different reception quality levels (ie, the configuration information is differentiated by time-frequency resources), and then can pass The strength of the uplink signal detected on the different time-frequency resources is used to determine the distribution of the UE reception quality level in the MBSFN area or in the cell. Of course, the distribution of UE reception quality levels in the MBSFN area or in the cell may also be determined according to the reception strength of different sequences transmitted on the same time-frequency resource.

In a specific implementation process, the configuration information of the uplink signal may include at least one of a sequence used by the uplink signal, a time resource of the transmission sequence, and a frequency resource of the transmission sequence, where the sequence may specifically be an m sequence or a Zad- Off Chu sequence, etc.; different reception quality levels may correspond to different sequences, or may correspond to different time resources, or may correspond to different frequency resources. The configuration information of the uplink signal may also include at least one of a load quantity of a data packet used by the uplink signal, a modulation and coding mode of the data packet, a time resource for transmitting the data packet, and a frequency resource for transmitting the data packet. Different receiving quality levels may correspond to different numbers of loads, or may correspond to different modulation and coding modes, or may correspond to different time resources, and may also correspond to different frequency resources. Optionally, in step S1201, the UE determines a current actual reception quality level according to the following steps:

The UE performs reception quality measurement based on the MBMS reference signal of the MBMS area, and determines a current actual reception quality level according to the measured result.

Optionally, before the sending, by the UE, the uplink signal, the method further includes: receiving, by the UE, an MBMS reception quality trigger signal; or

The sending, by the UE, the uplink signal includes: sending, by the UE, the uplink signal according to the acquired MBMS reception quality reporting period.

Optionally, the receiving, by the UE, an MBMS receiving quality trigger signal includes:

The UE performs channel estimation based on the MBMS reference signal of the MBMS region, and receives the MBMS reception quality trigger signal according to a result of channel estimation.

In the specific implementation process, the UE can report the MBMS reception quality level by using two mechanisms: a non-periodic mechanism and a periodic mechanism;

For the aperiodic mechanism, the UE needs to report the current actual reception quality level after receiving the MBMS reception quality trigger signal in the MBMS area, and the network side can send the trigger signal through the downlink control channel, where the trigger signal can carry the following information. At least one type of UE that needs to perform MBMS reception quality reporting (if there is no such list, all UEs in the MBMS area need to perform MBMS reception quality reporting), and the UE performs time-frequency code resources for MBMS reception quality reporting, and reports The number of times and other information. The trigger signal may be sent by the entire MBMS area, and the UE may perform channel estimation based on the MBMS reference signal, and receive the trigger signal according to the result of the channel estimation, where the MBMS reference signal is generated by using the area identifier of the MBMS area as a parameter. And the MBMS Single Frequency Network (MBSF) is used to transmit, that is, multiple cells are simultaneously transmitted in the MBMS area to ensure that all the UEs in the MBMS area can receive the trigger signal.

For the periodic mechanism, the UE needs to obtain the MBMS receiving quality of the MBMS region for a period of 4 ,, which may be obtained from the cell system message or pre-agreed with the network side.
