In addition to the embodiment of sending the uplink transmission information to all network-side access points 32 in the geographic area, in order to reduce the downlink air interface signaling burden, the central control node 31 may also notify only macro network-side access points (e.g., macro base stations) responsible for providing wide area coverage of the uplink transmission information.

Step 304, the network side access point 32 receives the common uplink transmission resource pool and the uplink transmission parameters from the central control node 31, and may periodically send the common uplink transmission resource pool and the uplink transmission parameters in the coverage area of the network side access point 32 in a system broadcast manner, and may start to attempt to receive possible uplink transmissions according to the common uplink transmission resource pool and the uplink transmission parameters. For the small network side access point, the common uplink transmission resource pool and the uplink transmission parameters may not be sent in a system broadcast manner from the viewpoint of energy saving, and in this case, the user equipment needs to receive the system broadcast of the macro network side access point.

It should be noted that, if the network-side access point 32 receives the common uplink transmission resource pool and the uplink transmission parameter from the central control node 31, and also receives the effective time and the effective period parameter of the common uplink transmission resource pool and the uplink transmission parameter, the network-side access point 32 stores the two parameters and sets the configuration to the failure state after the effective period parameter is overtime. If the network-side access point 32 does not receive the validation time and the validity period parameters, the network-side access point 32 considers that the previous configuration is valid until the common uplink transmission resource pool and the uplink transmission parameter update message are not received from the central control node 31.

Step 306, if the ue 33 obtains the common uplink transmission resource pool and the uplink transmission parameters from the system broadcast message of the cell where the ue currently resides, the ue 33 stores the configuration parameters, and tries to obtain the common uplink transmission resource pool and the uplink transmission parameters of the target cell through the system broadcast message of the target cell after the inter-cell movement occurs. If the current resident cell of the user equipment 33 does not send the configuration information of the common uplink transmission resource pool and the uplink transmission parameters in a cell system broadcast mode, the user equipment 33 may obtain the configuration information of the common uplink transmission resource pool and the uplink transmission parameters in a dedicated signaling mode by initiating a network access request to the network side access point 32.

Step 308, when the network access point 32 receives the network access request sent by the user equipment 33, it sends a network access response to the user equipment 33, where the network access response carries the public uplink transmission resource pool and the uplink transmission parameters.

In step 310, after the uplink data arrives, the ue 33 selects a suitable uplink transmission resource (e.g., an idle uplink transmission resource) from the common uplink transmission resource pool according to the common uplink transmission resource pool configuration of the current area, and performs uplink data transmission using the uplink transmission parameter configuration. The network side access points 32 around the user equipment 33 will attempt to receive on the uplink transmission resources indicated by the common uplink transmission resource pool using the uplink transmission parameters. If the user equipment 33 supports multiple RAT types, uplink data transmission may be performed in multiple RATs according to uplink transmission resources and uplink transmission parameter configurations on different RAT types.

Second embodiment, dynamic uplink transmission information configuration scheme based on geographic area

In a dynamic uplink transmission information configuration scheme based on a geographic area, a network side access point is configured with a common uplink transmission resource pool and uniform uplink transmission parameters in a certain geographic area (for example, in a geographic area covered by a plurality of macro network side access points and small network side access points together), wherein the common uplink transmission resource pool is shared by all user equipment in the current geographic area, and all the user equipment use uplink transmission resources in the common uplink transmission resource pool in a preemptive manner or a network side access point scheduling manner. The user equipment receives the relevant scheduling information of the current subframe public uplink transmission resource pool on the downlink control channel, and selects an uplink transmission resource from the effective public uplink transmission resource pool of the current subframe for uplink data transmission after the uplink data arrives. The common uplink transmission resource pool and the uplink transmission parameters are determined by the central control node and configured to the network side access point in the geographic area by the central control node, and the common uplink transmission resource pool itself may change very frequently, for example, on each uplink subframe, the scheduling information related to the common uplink transmission resource pool may be different.

As a more specific embodiment, as shown in fig. 4, the dynamic uplink transmission information configuration scheme based on a geographic area includes the following steps:

step 402, the central control node 41 determines the public uplink transmission resource pool and the uplink transmission parameters in the specific area, and notifies all network side access points 42 in the geographic area of the above information, and in addition, may also carry an effective time to indicate the effective time of the public uplink transmission resource pool and the uplink transmission parameters. In the scheme for dynamically configuring the uplink transmission information, the default valid time of each configuration is a minimum transmission time interval (e.g., a subframe) in the system. Therefore, the central control node 41 will send the common uplink transmission resource pool and the uplink transmission parameters to the network-side access point 42 in a period of the minimum transmission interval. In the case of supporting multiple RAT types, the central control node 41 configures uplink transmission parameters for different RAT types, and configures the uplink transmission parameters to corresponding network side access points 42 in each RAT. The central control node 41 may notify the network-side access point 42 of the uplink transmission information by unicast, multicast, or broadcast. In addition to the embodiment of sending the uplink transmission information to all network-side access points 42 in the geographic area, in order to reduce the signaling burden of the downlink air interface, the central control node 41 may also notify only the macro network-side access point responsible for providing wide area coverage of the uplink transmission information.

Step 404, after the network side access point 42 receives the common uplink transmission resource pool, the uplink transmission parameter and the validation time parameter from the central control node 41, the common uplink transmission resource pool and the uplink transmission parameter are sent in the cell through the downlink control channel at the validation time, and after the user equipment 43 receives the common uplink transmission resource pool and the uplink transmission parameter that can be used in the cell at the current time through the downlink control channel, if uplink data to be transmitted in the cache of the user equipment 43 is to be transmitted, uplink data transmission can be performed according to the common uplink transmission resource pool and the uplink transmission parameter. If the small network side access point does not send the uplink transmission information, the ue 43 needs to receive the uplink transmission information through the downlink control channel of the macro network side access point.

In step 406, the ue 43 selects a suitable uplink transmission resource from the common uplink transmission resource pool according to the size of the uplink data to be transmitted in the Buffer (Buffer) and performs uplink data transmission according to the uplink transmission parameter configuration. The network side access point 42 around the user equipment 43 attempts to receive using the uplink transmission parameters on the uplink transmission resources indicated by the common uplink transmission resource pool at the uplink transmission time according to the scheduling information. If the user equipment 43 supports multiple RAT types, uplink data transmission can be performed in multiple RATs according to uplink transmission resources and uplink transmission parameter configurations on different RAT types.

It should be noted that, in the semi-static uplink transmission information configuration scheme and the dynamic uplink transmission information configuration scheme mentioned in the embodiments of the present invention, both the semi-static state and the dynamic state refer to an indication manner of an uplink transmission resource, and specifically, in the semi-static uplink transmission information configuration scheme, an effective time and an effective period for uplink transmission resource and uplink transmission parameter configuration are always effective in the effective period; in the scheme for configuring the dynamic uplink transmission information, the validity period of the time when the uplink transmission resource and the uplink transmission parameter are configured to be valid defaults to a minimum transmission time interval (for example, one subframe) in the system.

The scheme that the central control node configures uplink transmission information according to the position of the user equipment is divided into the following three cases, specifically:

when determining the uplink transmission information corresponding to at least one network side access point according to the location information or the probe signal list reported by the user equipment, before determining the uplink transmission information corresponding to at least one network side access point, the method further includes: receiving position information or a detection signal list reported by user equipment; determining a network access point list corresponding to the user equipment according to the position information of the user equipment and the position information of a pre-stored network side access point; or determining a network access point list corresponding to the user equipment according to a detection signal list reported by the user equipment; alternatively, the first and second electrodes may be,

when determining the uplink transmission information corresponding to at least one network side access point according to a random access process initiated by user equipment, before determining the uplink transmission information corresponding to at least one network side access point, the method further comprises: receiving position information reported by user equipment; configuring a special random access resource corresponding to the user equipment, wherein the special random access resource is used for indicating the user equipment to send a random access message to a network side access point by using the special random access resource when uplink data arrives; when receiving a random access message sent by a network side access point, determining a network access point list corresponding to user equipment sending the random access message according to the position of the network side access point; alternatively, the first and second electrodes may be,

when determining the uplink transmission information corresponding to at least one network side access point according to a random access process initiated by user equipment, before determining the uplink transmission information corresponding to at least one network side access point, the method further comprises: determining a preset public random access resource of a specific area, wherein the public random access resource is used for indicating user equipment to send a random access message to a network side access point by using the public random access resource when uplink data arrives; sending the public random access resource to a network side access point in a specific area; when receiving a random access message sent by a network side access point, determining a network access point list corresponding to user equipment sending the random access message according to the position of the network side access point; determining uplink transmission information corresponding to at least one network side access point, specifically: and determining uplink transmission information corresponding to at least one network access point in the network access point list.

The method is specifically divided into the following three embodiments:

first implementation mode, semi-static uplink transmission information configuration scheme based on user equipment location information

And the central control node reports and updates and judges the position of the user equipment according to the position information of the user equipment, and determines a network side access point list corresponding to the user equipment. The central control node pre-configures uplink transmission resources and uplink transmission parameters for the network side access points and the user equipment in the network side access point list, and the user equipment directly transmits uplink data according to the uplink transmission resources and the uplink transmission parameters after the uplink data arrives.

As a more specific embodiment, as shown in fig. 5, the configuration scheme of semi-static uplink transmission information based on the location information of the ue includes the following steps:

in step 502, after the ue 53 is powered on, or its location changes, or the measurement on the neighboring cell changes, it reports its location or a probe list to the central control node 51, where the location information of the ue 53 may be the geographical location information (e.g., positioning information) of the ue 53, and the probe list is a list composed of reference signals or synchronization signals sent by the network-side access point 52 measured by the ue 53.

The central control node 51 determines a network-side access point list corresponding to the user equipment 53 according to the geographical location information of the user equipment 53 and the geographical location information of the network-side access point 52 stored in advance, for example: adding the network-side access point 52, whose distance from the user equipment 53 is smaller than the preset threshold, to the network-side access point list corresponding to the user equipment 53, where the preset distance may be set according to an actual situation, for example: 1 kilometer. The network-side access point may also determine a network-side access point list corresponding to the user equipment 53 according to the probe signal list, for example: the network-side access point 52 that transmits the reference signal or the synchronization signal in the probe signal list is added to the network-side access point list corresponding to the user equipment 53. In addition, in the case that the user equipment 53 supports multiple RATs, the user equipment 53 notifies the central control node 51 of RAT information supported by itself.

In step 504, the central control node 51 determines a network-side access point list corresponding to the user equipment 53 according to the location information or the probe signal list reported by the user equipment 53, and configures uplink transmission resources and uplink transmission parameters used for uplink data transmission for the user equipment 53. The central control node 51 configures the uplink transmission resource, the uplink transmission parameter, the validation time and the validity period information to the user equipment 53. Of course, it will be understood by those skilled in the art that the central control node 51 configures the uplink transmission information to the user equipment 53, and needs to be transmitted to the user equipment 53 through the network-side access point 52. In the case that the user equipment 53 supports multiple RATs, the central control node 51 may notify the user equipment 53 of uplink transmission resources and uplink transmission parameters of the multiple RATs.

In step 506, the central control node 51 sends the configuration parameters such as the terminal identification information, the uplink transmission resource, the uplink transmission parameter, the validation time, the validity period, and the like to the network-side access point 52 according to the determined network-side access point list corresponding to the user equipment 53. After receiving the configuration parameters, the network access point 52 attempts to receive the uplink data transmission of the user equipment 53 after the configuration becomes effective. In the case of supporting multiple RATs, the network-side access point list generated by the central control node 51 includes network-side access points 52 of different RAT types.

In step 508, after the uplink data of the ue 53 arrives, the uplink data is transmitted by using the uplink transmission parameters according to the uplink transmission resources. The network side access points around the user equipment 53 will attempt to receive on the uplink transmission resources using the uplink transmission parameters. If the multi-RAT uplink transmission resource and the uplink transmission parameter are configured, the ue 53 may perform uplink data transmission in the multi-RAT.

Second embodiment, dynamic uplink transmission information configuration scheme based on random access mode, user equipment initiates random access message by using special random access resource

As a more specific embodiment, as shown in fig. 6, the scheme for configuring the dynamic uplink transmission information in the random access mode includes the following steps:

step 602, after the ue 63 is powered on, or its location changes, or the measurement of the neighboring cell changes, it reports its location information to the central control node 61, and if the ue 63 supports multiple RAT types, the ue 63 notifies the central control node 61 of the RAT information supported by itself.

In step 604, the central control node 61 allocates a dedicated random access resource to the ue 63 according to the location information of the ue 63. The allocation of so-called dedicated random access resources (dedicated scheduling request resources) herein aims to ensure that there is no collision between multiple user equipments which are identical or have overlapping network-side access point lists due to the use of exactly the same random access resources (or scheduling request resources). The central control node 61 informs the user equipment 63 of the dedicated random access resources (dedicated scheduling request resources). Wherein the dedicated random access resources (dedicated scheduling request resources) may be for a single RAT or for multiple RATs.

In step 606, after the uplink data arrives, the user equipment 63 initiates a random access process according to the dedicated random access resource (dedicated scheduling request resource), that is, sends a random access message to the network side access point 62.

In step 608, the network-side access point 62 that correctly receives the random access (or scheduling request) message sends the received random access (or scheduling request) message to the central control node 61.

Step 610, the central control node 61 generates a network side access point list corresponding to the user equipment 63 according to the network side access point 62 which detects and reports the random access message, and determines the uplink transmission resource and the uplink transmission parameter, and the effective time. The central control node 61 notifies the user equipment 63 of the uplink transmission resource, the uplink transmission parameter and the effective time information, and the user equipment 63 stores the uplink transmission information obtained from the central control node 61. In case the user equipment 63 supports multiple RATs, the central control node 61 may inform the user equipment 63 of uplink transmission resources and uplink transmission parameters of multiple RATs.

Step 612, the central control node 61 notifies all network side access points 62 in the network side access point list corresponding to the user equipment 63 of the uplink transmission resource, the uplink transmission parameter and the effective time, and the network side access points 62 store the uplink transmission information obtained from the central control node 61. In the case of supporting multiple RATs, the network-side access point list generated by the central control node 61 includes network-side access points of different RAT types.

Step 614, at the uplink transmission time, the ue 63 performs uplink data transmission according to the uplink transmission resource and the uplink transmission parameter obtained before. All the network access points 62 in the network access point list corresponding to the user equipment 63 attempt to receive the uplink data transmission of the user equipment 63 at the uplink transmission time. The user equipment 63 may perform uplink data transmission on the multi-RAT type if the multi-RAT uplink transmission resources and uplink transmission parameters are configured.

In the third embodiment, the scheme for configuring the dynamic uplink transmission information based on the random access mode is that the user equipment initiates a random access message by using a public random access resource

As a more specific embodiment, as shown in fig. 7, the scheme for configuring the dynamic uplink transmission information in the random access mode includes the following steps:

in step 702, after determining the public random access resource (public scheduling request resource) used in the specific area, the central control node 71 notifies all network side access points 72 in the specific area of the public random access resource.

Step 704, the network side access point 72 stores the public random access resource and broadcasts the public random access resource pool in the cell by the cell system broadcasting.

In step 706, after the uplink data arrives, the ue 73 initiates a random access process according to the public random access resource obtained from the system broadcast message, that is, sends a random access message to the network side access point 72. If the user equipment 73 supports multiple RAT types, the user equipment 73 may attempt to initiate a random access procedure in multiple RATs simultaneously.

In step 708, the network-side access point 72 that correctly receives the random access message forwards the received random access message to the central control node 71.

Step 710, the central control node 71 generates a network side access point list corresponding to the user equipment 73 that sends the random access message according to the network side access point 72 that detects and reports the random access message, determines the uplink transmission resource, the uplink transmission parameter, and the effective time, and sends the uplink transmission resource, the transmission parameter, and the effective time to all network side access points 72 in the network side access point list.

In step 712, the network side access point 72 stores the uplink transmission resource, the uplink transmission parameter and the effective time, and after the scheduling effective time is reached, the network side access point 72 sends the scheduling information of the uplink transmission resource and the uplink transmission parameter to the user equipment 73 through the downlink control channel.

In step 714, the ue 73 performs uplink data transmission at the uplink scheduling time according to the uplink transmission resource and the uplink transmission parameter indicated by the downlink control channel, and carries the ue identifier (e.g., the mobile phone number). All network access points 72 in the network access point list attempt to receive uplink data of the user equipment 73 at the uplink transmission time. The ue id is used to assist the network access point 72 to distinguish multiple ues using the same uplink transmission resource for uplink data transmission. If the user equipment 73 supports multiple RATs, the user equipment 73 may attempt to initiate an uplink data transmission procedure in the multiple RATs.
