Description

Information transmission and processing method and device, equipment, terminal and system

Technical Field

The present invention relates to the field of mobile communications, and in particular, to an information transmission method, an information processing method, an information transmission apparatus, an information processing apparatus, a terminal, and an information transmission system.

Background

In a Long Term Evolution (LTE) system, a base station uses a Physical Downlink Control Channel (PDCCH) to transmit a Control signaling for scheduling a User Equipment (User Equipment, UE for short), and when scheduling data of a connected UE, the Control signaling includes a Cell Radio Network Temporary Identity (C-RNTI), that is, the C-RNTI of the UE is used for masking, the Control signaling includes a Physical Channel resource allocated to the UE and a Modulation and Coding Scheme (MCS) used for the UE, and after receiving the Control signaling transmitted on the PDCCH, the UE parses related information carried in the Control signaling, and transmits and receives data on a corresponding Physical Channel according to an instruction therein. In a massive Machine Type Communication (mtc) scenario, there are mass devices that need to access and perform data transmission. At this time, each UE is still scheduled by using the PDCCH scrambled by the UE-level C-RNTI, which may cause a large amount of PDCCH signaling overhead. Therefore, schemes such as scheduling based on a device group are currently proposed. However, in the current scheme of scheduling based on the device group, how to notify the UE of the information of the device group is still not clear, and in the current scheme, the base station needs to send signaling to each UE to notify group information such as a group ID, so that the signaling overhead is huge in an mtc scenario.

In view of the above technical problems, no effective solution has been proposed at present.

Preferred embodiment 1

Fig. 8 is a flowchart illustrating a method according to preferred embodiment 1 of the present invention, and as shown in fig. 8, the present preferred embodiment provides a method for notifying group information, which includes:

step 801: the base station groups the equipment according to at least one of the service characteristics, the service types, the equipment positions, the equipment types, the resources when the equipment is accessed, the scheduling resources and the like of the equipment; wherein devices like traffic characteristics or traffic types or device locations or device types may be grouped into a plurality of groups.

Step 802: the base station notifies the device of the group information. Wherein the group information at least includes a group identity (or group ID) which can be used as a group C-RNTI to mask the control information carried in the PDCCH related to the group, or the group identity (or group ID) can be used to generate the group C-RNTI and to mask the control information carried in the PDCCH related to the group using the group C-RNTI. The group information may further include group SPS (semi-persistent scheduling) information, and/or group DTX information, and/or an indication of group semi-statically occupied resources, where the indication of semi-statically occupied resources at least includes indications of time domain and frequency domain resources, and may further include indications of space domain resources and code domain resources.

Wherein, the group information notification at least adopts one of the following schemes:

the first scheme is as follows: group information broadcasting: the base station informs the group information of the device through broadcast signaling. The group information may be broadcast, either explicitly (e.g., in a list) or implicitly (e.g., for a device or a type of device accessed on a certain resource, automatically corresponding to a certain group). If explicit notification (for example, in the form of a list) is adopted, the sequence number of the device in the group may be displayed in the list, or implicit notification may be adopted (that is, the sequence number of the device in the group is related to the sequence order of the device appearing in the list). A certain segment of time-frequency resources may refer to a certain subframe set, a certain subframe, a certain PRB or PRB set, a certain PRB set of a certain subframe, or a certain PRB set on a certain subframe on a certain subcarrier, and so on.

Scheme II: multicast of group information: the base station informs the group information of the devices of a certain device set through the signaling of the device set. Wherein each device of the set belongs to the same group, or each device of the set belongs to a different group.

The device set may be a set of one or more types of devices that have transmitted an uplink channel on a certain segment of time-frequency resources, a set of one or more types of devices that have received a downlink channel on a certain segment of time-frequency resources, or a device set determined by other methods. A certain segment of time-frequency resources may refer to a certain subframe set, a certain subframe, a certain PRB or PRB set, a certain PRB set of a certain subframe, or a certain PRB set on a certain subframe on a certain subcarrier, and so on.

The multicast form of the group information may be an explicit notification (e.g., in the form of a list) or an implicit notification (e.g., a device accessed on a certain resource or a certain type of device automatically corresponds to a certain group). Wherein, if explicit notification (for example, in the form of a list) is adopted, the sequence number of the device in the group may be displayed in the list, or implicit notification may be adopted (that is, the sequence number of the device in the group is related to the sequence appearing in the list);

the third scheme is as follows: the group information is unicast in combination with broadcast or multicast. The base station informs the key group information of the group to which the UE belongs through the RRC signaling of the UE, and then informs other group information of the group to which the user equipment belonging to the group belongs through a broadcasting or multicasting mode. Wherein the key group information includes at least a group identification (or group ID) or signaling that may indicate reception of other group information. The base station then informs the group information of the group to which the user equipment belonging to the group belongs in a broadcast or multicast mode, which is similar to the first scheme or the second scheme, and is not described here again.

And the scheme is as follows: group information broadcast and multicast are combined. The base station informs the key group information of the group to which the equipment belongs through broadcast signaling, and then informs other group information of the group to which the user equipment belonging to the group belongs through a multicast mode. Wherein the key group information includes at least a group identification (or group ID) or signaling that may indicate reception of other group information. The base station then informs the group information of the group to which the user equipment belonging to the group belongs in a broadcast or multicast mode, which is similar to the first scheme or the second scheme, and is not described here again.

Step 803: user equipment receives a group information notification signaling sent by a base station;

wherein the group information at least includes a group identity (or group ID) which can be used as a group C-RNTI to mask the control information carried in the PDCCH related to the group, or the group identity (or group ID) can be used to generate the group C-RNTI and to mask the control information carried in the PDCCH related to the group using the group C-RNTI. The group information may further include group SPS (semi-persistent scheduling) information, and/or group DTX information, and/or an indication of group semi-statically occupied resources, where the indication of semi-statically occupied resources at least includes indications of time domain and frequency domain resources, and may further include indications of space domain resources and code domain resources.

Wherein, the group information acquisition at least adopts one of the following schemes:

the first scheme is as follows: the user equipment acquires the group information by broadcasting: the user equipment acquires the group information to which the user equipment belongs through the broadcast signaling. The group information may be broadcast, either explicitly (e.g., in a list) or implicitly (e.g., for a device or a type of device accessed on a certain resource, automatically corresponding to a certain group). If explicit notification (for example, in the form of a list) is adopted, the sequence number of the device in the group may be displayed in the list, or implicit notification may be adopted (that is, the sequence number of the device in the group is related to the sequence order of the device appearing in the list). A certain segment of time-frequency resources may refer to a certain subframe set, a certain subframe, a certain PRB or PRB set, a certain PRB set of a certain subframe, or a certain PRB set on a certain subframe on a certain subcarrier, and so on.

Scheme II: the user equipment learns the group information through multicast: the user equipment acquires the group information of the equipment of a certain equipment set through the signaling of the equipment set. Wherein each device of the set belongs to the same group, or each device of the set belongs to a different group.

the third scheme is as follows: the group information is learned by means of a combination of unicast and broadcast or multicast. The user equipment acquires the key group information of the group to which the UE belongs through the RRC signaling of the UE, and then acquires other group information of the group to which the user equipment belongs through a broadcasting or multicasting mode. Wherein the key group information includes at least a group identification (or group ID) or signaling that may indicate reception of other group information. The group information of the group to which the user equipment belonging to the group belongs is similar to the first scheme or the second scheme through the broadcast or multicast mode of the user equipment, and is not described again here.

And the scheme is as follows: the group information is known by means of a combination of broadcast and multicast. The user equipment acquires the key group information of the group to which the equipment belongs through the broadcast signaling, and then acquires other group information of the group to which the user equipment belongs through a multicast mode. Wherein the key group information includes at least a group identification (or group ID) or signaling that may indicate reception of other group information. The group information of the group to which the user equipment belonging to the group belongs is similar to the first scheme or the second scheme through the broadcast or multicast mode of the user equipment, and is not described again here.
