detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

First, some of the terms in this application are explained to be understood by those skilled in the art.

1) The base station is a Radio Access Network (RAN) device, which is used to connect the terminal to the wireless network, including but not limited to: an evolved Node B (eNB), and a wireless network control. Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (for example, Home evolved NodeB, or Home Node B, HNB), Base Band Unit (BBU), Wifi Access Point (AP), etc.

2) A terminal, also known as a User Equipment (UE), is a device that provides voice and/or data connectivity to a user, for example, a handheld device with wireless connectivity, an in-vehicle device, and a connection to Other processing devices for wireless modems, etc. At present, the demand of the base station for the terminal is often judged by the auxiliary measurement, and then the terminal is configured with parameters or resources that satisfy the requirements as much as possible. However, this approach does not really meet the needs of the terminal in various scenarios. The present application considers that if the terminal can directly inform the base station of the demand, it is more advantageous to configure the terminal. Moreover, for different terminal manufacturers, customized network side configuration parameters can also be obtained based on this; or, the terminal wants to obtain some state information of the network side so that the service can be performed better. For example, in order to save power for a terminal, different terminal manufacturers may configure a set of discontinuous reception (DRX) configuration parameters according to the most power-saving mode expected by the terminal in different scenarios, or before the terminal performs certain services. I hope to know the resource information on the network side.

In the communication process between the base station and the terminal, the logical channel identifier (LCID) field in the Medium Access Control (MAC) header is used to indicate MAC Service Data Unit (SDU), MAC Control Element (CE) (hereinafter referred to as Media Access Control Cell) or patch (padding) carried in a MAC Protocol Data Unit (PDU) ). Please refer to FIG. 1 , which is a schematic structural diagram of a MAC PDU. As shown in FIG. 1 , the MAC PDU includes a MAC header, a MAC SDU, a MAC CE, and a patch. Of course, the number of MAC SDUs and MAC CEs may be different according to the situation of the interaction information, and may even be 0. The patches may or may not exist according to specific situations.

The MAC header includes one or more subheaders. The normal MAC PDU subheader consists of six fields (R/R/E/LCID/F/L), and the L domain can be in the form of 7 bits and 15 bits. For the last one The subheader, the fixed length MAC CE, and the subheader corresponding to the patch include four domains (R/R/E/LCID). Where R is a reserved bit (referred to as a reserved bit) and is set to "0"; E is used to indicate whether the MAC header has multiple domains, for example, when E=1, it means that another set of "R" exists next. /R/E/LCID" field, when E=0, means that the next is the MAC load; the LCID is used to identify which logical channel the corresponding load (for example, MAC CE, MAC SDU or patch) originates from; Indicates the length of the L field; L is used to indicate the length of the MAC SDU or control message.

The value range of the LCID is determined. Refer to Table 1 and Table 2 for the setting of the LCID value of the downlink shared channel and the uplink shared channel. The method includes a reserved LCID value, and the present application uses the reserved LCID of the uplink shared channel to request the terminal from the terminal, and uses the reserved LCID of the downlink shared channel to respond to the requirement of the terminal, so that Through the reserved MAC CE and the terminal to do some custom information interaction, such as the terminal requesting the network side load situation, requesting some parameters more favorable to oneself, reporting the load of the user, etc., the base station makes some specifics to the terminal according to the situation reported by the terminal. The processing meets the requirements of the terminal, so that the customization requirements of the terminal can be better realized, and the service quality of the terminal is improved. In addition, both the request and the reply are completed by the MAC CE indicated by the reserved LCID, so that the information interaction can be made simpler and the realization of the base station and terminal customization requirements can be realized at a lower cost without going through higher layer processing.

Table 1: List of settings for the value of the logical channel identifier for the downlink shared channel (Values of LCID for DL-SCH)

Table 2: List of values for the value of the logical channel identifier of the uplink shared channel (Values of LCID for UL-SCH)

The process of the above information interaction is exemplified below with reference to the accompanying drawings.

Please refer to FIG. 2 , which is a signaling flow diagram of a method for information interaction according to an embodiment of the present invention. As shown in FIG. 2, the method is applied to a wireless communication system, and the system includes a terminal and a base station, and the terminal passes The base station accesses the wireless network. And the method comprises the following steps:

S201: The terminal sends a request message to the base station, where the request message is used to request the information that the terminal wants to obtain from the base station, where the request message is transmitted by the MAC CE indicated by the first LCID, and the first LCID is a reserved LCID, for example, Any one of 01100 to 10101.

The terminal uses the MAC CE to make a request to the base station, carries the request in the MAC CE, and uses the reserved LCID to inform the base station that this is the information requested by the terminal to the base station, so that the base station knows the terminal requirements and meets the requirements of the terminal. It should be noted that the requirements herein may be any kind of requirements, for example, may be status information, resource information, and the like on the network side that the terminal desires to obtain. It can also be the configuration required by the terminal, and the like. In summary, the present application does not impose any restrictions on the content of the request message request, and may be customized between the base station and the terminal, and different terminals may also be different.

S202: The base station receives the request message sent by the terminal, and sends the information that the terminal wants to obtain to the terminal by using a reply message, where the reply message is transmitted by the media access control cell indicated by the second LCID, where the second LCID is the reserved LCID. For example, any of 01011 to 11001.

After receiving the MAC PDU sent by the terminal, the base station finds that there is a MAC CE indicated by the reserved LCID, and the request of the terminal carried by the MAC CE, so that the base station can respond to the request according to the request message of the terminal. At this time, the base station also facilitates the reply message by facilitating the reserved LCID.

In this way, the terminal can use the reserved LCID of the uplink shared channel to make a request to the base station, and the base station uses the reserved LCID of the downlink shared channel to respond to the requirement of the terminal, so that the reserved MAC CE and the terminal can be used to do some Customized information interaction, such as the terminal requesting network-side load conditions, requesting certain parameters that are more favorable to oneself, and reporting their own load, etc. The base station performs some specific processing on the terminal to meet the terminal requirements according to the reporting situation of the terminal, thereby being better. Realize the customization needs of the terminal and improve the service quality of the terminal. In addition, both the request and the reply are completed by the MAC CE indicated by the reserved LCID, so that the information interaction can be made simpler and the realization of the base station and terminal customization requirements can be realized at a lower cost without going through higher layer processing.

The LCID of the uplink reservation has an intersection with the LCID of the downlink reservation. Preferably, the foregoing embodiment may be implemented by using the intersection part, that is, the first LCID and the second LCID are the same. In this way, both the request message and the reply message are transmitted through the logical channel indicated by the same LCID, which is simple to implement. Of course, the first LCID and the second LCID may also be different, that is, the request message and the reply message are indicated by different LCIDs.

In addition, the present application does not impose any restrictions on the manner in which the terminal selects the first LCID. For example, the terminal may select by traversing, and may traverse the unused LCID in the reserved LCID of the uplink shared channel as the first LCID. The request message is sent by using the logical channel indicated by the LCID. As another example, the first LCID used by the terminal can be configured by the base station, for example, by RRC signaling.

In addition, before the terminal sends the request message to the base station, the terminal may first obtain the consent of the base station to perform the above interaction. For example, the terminal may initiate a handshake process to the base station. After the handshake is successful, the terminal performs the above interaction, so that the base station can control which of the terminals to perform such customized information interaction, which is more beneficial to guarantee the quality of service of the terminal. The following is described in detail in conjunction with the drawings:

Please refer to FIG. 3, which is a signaling flow diagram of another method for information interaction according to an embodiment of the present invention. The method includes the following steps:

S301: The terminal sends a handshake message to the base station.

S302: The base station receives the handshake message, and sends a response message of the handshake message to the terminal.

Through the handshake, the base station can negotiate a private protocol with the terminal to establish a handshake relationship and a channel for the dedicated information exchange between the two. Here, the dedicated information exchange channel refers to the logical channel indicated by the reserved LCID, and the uplink and downlink may be the same or different.

S303: The terminal sends a request message to the base station, requesting to obtain the information that it wants.

S304: The base station receives the request message sent by the terminal, and sends the information that the terminal wants to obtain to the terminal by using a reply message.

The handshake message is used to indicate that the terminal supports the message exchange with the base station by using the logical channel indicated by the reserved LCID, and the base station replies with a response message to the terminal to agree to the handshake, and establishes a handshake relationship between the two. When the base station refuses to handshake, the terminal may not reply the response message to the terminal, so that the terminal can know that the handshake is unsuccessful, and does not use the logical channel indicated by the reserved LCID to perform message interaction with the base station. Certainly, when the base station rejects the handshake, the base station may also reply the rejected response message to the terminal to notify the terminal that the handshake fails.

In S301, the terminal may send a handshake message by using the MAC CE indicated by the reserved LCID, so that the subsequent terminal can continue to use the LCID used in the handshake process as the first LCID to perform information interaction with the base station, which simplifies the process and saves overhead. . Of course, the terminal can also complete the handshake with the base station in other manners. For example, the handshake process can be completed through RRC signaling, or the reserved LCID can be specified through RRC signaling. In summary, the present application does not limit the implementation of the handshake process, as long as the handshake between the terminal and the base station can be implemented.

A private protocol between the base station and the terminal can be established by sending and responding to the handshake message, and a dedicated channel between the two is established. The above handshake process may be performed by reserving the MAC CE indicated by the LCID. The specific process may be: the terminal sends a handshake message to the base station, and the base station may parse the MAC CE indicated by the reserved LCID when the MAC layer resolves to the MAC CE. The handshake message, so as to understand the handshake requirement of the terminal, after the base station responds to the handshake message or affirmatively responds to the handshake message, it can negotiate with the terminal part or all of the MAC CE of the reserved LCID for subsequent information interaction, the present invention The embodiment is not limited at all. Then, the negotiated information is notified to the terminal through the reply message, and the terminal can use the media access control cell of the negotiated reserved LCID to perform information interaction with the base station, and obtain related information of the peer device, thereby completing the service transmission better. .

It should be noted that the base station and the terminal may not handshake. In this case, the base station may identify the terminal through the process of interaction between the existing terminal and the base station, and determine that the terminal needs to perform customized information interaction, thereby instructing the terminal to use the reservation. The LCID interacts with the base station for information. In contrast, the base station and the terminal handshake, and the handshake message is sent by the MAC CE indicated by the reserved LCID during the handshake, so that the base station can implement the interaction of the subsequent information by using the logical channel indicated by the LCID. At this point, save money.

In addition, the handshake can also be implemented in other manners, that is, not implemented by the MAC CE indicated by the reserved LCID. At this time, the base station may specify the reserved LCID used by the base station, or the terminal may select it by itself. The manner in which the base station specifies the reserved LCID for the terminal is not limited. The RRC signaling may be specified by the RRC signaling, or may be specified by using a system message.

Please refer to FIG. 4 , which is a schematic flowchart of a method for information interaction according to an embodiment of the present invention. The method includes the following steps:

S401: The base station receives the request message sent by the terminal, where the request message is transmitted by the media access control cell indicated by the first logical channel identifier LCID, where the request message is used to request, from the base station, the information that the terminal wants to obtain. Wherein the first LCID is any one of 01100 to 10101.

The request message may be used to notify the base station of the service requirement of the terminal, request the base station to obtain a service configuration parameter, or request to acquire current resource occupation information of the base station.

S402: The base station sends the information that the terminal wants to obtain to the terminal by using a reply message, where the reply message is transmitted by the media access control cell indicated by the second LCID.

Wherein the second LCID is any one of 01011 to 11001.

Optionally, the first LCID is the same as the second LCID.

It can be seen that, in the above method, the base station and the terminal can receive and send the request message and the reply message by using the media access control cell that reserves the LCID, so as to implement the information interaction of the peer device, and the terminal can be embodied in the request message. The information that is to be obtained is such that the base station can accurately understand the service requirements of the terminal in different services and in different scenarios, thereby facilitating the base station to configure appropriate service configuration parameters for the terminal, scheduling appropriate resources to cooperate with the terminal to complete service transmission, and the terminal can also The information of the base station is obtained, so that the appropriate resources can be selected at the appropriate time to reduce the resource pressure of the base station; the information interaction between the two can greatly improve the network performance, improve the efficiency and quality of the service, and improve the user experience.

In the above step S201, the request message is used to notify the base station of the service requirement of the terminal, requesting the base station to acquire a service configuration parameter or requesting to acquire current resource occupation information of the base station. The service configuration parameters may include, but are not limited to, quality of service (QoS) for a certain service, channel reception quality, average reception level, signal transmission power, signal working frequency band, data transmission rate, path loss, and the like. . For example, for services with higher timeliness, you need to configure higher signal transmission power and data transmission rate. Other parameters can be configured normally. For services with higher quality requirements, you need to configure higher channel reception quality and lower. Path loss; for services with large data volume but not time-sensitive, a larger signal operating frequency band can be configured. The embodiment of the present invention is not limited in any way.

For the current resource occupation information of the base station, it may include, but is not limited to, occupation information of the time domain resource and the frequency domain resource, such as occupancy information of the channel. When a certain channel is idle, the terminal may directly initiate a resource request message requesting to use the idle resource to complete the service transmission after acquiring the current resource occupation information of the base station, and when the channel is occupied by other terminals, the terminal is aware of the After the information is received, the resource request message may be sent after a period of time, or the information acquisition message may be sent to obtain the latest current resource occupation information of the base station. Of course, when the channel is occupied, the base station may notify the terminal to indicate that it has passed a certain period of time. Initiate a resource request.

Optionally, before the foregoing step S402, after receiving the request message initiated by the terminal, the base station needs to occupy part of the time for collecting the service configuration parameter or the current service information. At this time, the base station may first send a corresponding response message to the terminal to notify The terminal has received the request message it sent and is processing it. So that the terminal knows the working state of the base station and waits for the processing result of the receiving base station.

Of course, the response message may not be sent, and the response message may be sent directly to the terminal directly after collecting the related information. Therefore, the terminal acquires the service configuration parameter that it wants or the current resource occupation information of the base station.

S502: The base station sends a response message to the terminal.

The response message is used to notify the terminal that the base station agrees to handshake with the terminal.

A private protocol between the base station and the specific terminal can be established by sending and responding to the handshake message, and a dedicated channel between the two is established. The process of completing the handshake by the media access control cell that reserves the LCID is as follows: the terminal sends a handshake message to the base station, and when the media access control layer resolves the message to the reserved LCID, the base station can parse the handshake message to obtain the handshake. The information is used to understand the handshake requirement of the terminal. After the base station responds to the handshake message, the base station can negotiate with the terminal for part or all of the media access control cell of the reserved LCID. . Then, the negotiated information is notified to the terminal through the reply message, and the terminal can use the media access control cell of the negotiated reserved LCID to perform information interaction with the base station, and obtain related information of the peer device, thereby completing the service transmission better. .

The handshake message may be sent by the media access control cell indicated by the first LCID. The sending channel of the response message may be the same as the sending channel of the handshake message, or may be different, and is not limited in any embodiment of the present invention.

When the information is exchanged, the information acquired by the terminal depends on the specific content of the information acquisition request message. If the terminal wants to obtain the optimized service configuration parameter of the current service according to the service requirement of the terminal, the information acquisition request message is used to notify the base station of the service requirement of the terminal, to the base station. Requesting to obtain the service configuration parameter; if the terminal wants to know the current resource occupancy of the base station to determine whether to initiate the resource request message, the information acquisition request message is used to request to acquire the current resource occupation information of the base station. The subsequent processing flow of the base station according to different contents of the information acquisition request message will be respectively described below with reference to FIG. 6 and FIG. 7.
