TECHNICAL FIELD
The present invention relates to the field of communications technologies and, in particular, to a method for group scheduling grant, a user equipment and a radio network controller.
BACKGROUND
With the rapid development of communications technologies, as one of the main technologies for the third generation mobile communication systems, the wideband code division multiple access (WCDMA for short) has been widely researched and applied on a global scale. At present, there are multiple WCDMA releases including the ninety-ninth release (Release 99; R99 for short), the fourth release (Release4; R4 for short), the eleventh release (Release 11; R11 for short) and etc.
In the WCDMA R6 release, optimizations and evolutions are performed for uplink packet service, and the high speed uplink packet access (HSUPA for short) technology is introduced. Similar to the HSDPA technology, the HSUPA adopts hybrid automatic repeat request (HARQ for short), fast scheduling based on a base station (Node B) and a 2 ms Transmission Time Interval (TTI for short) short frame transmission. The HSUPA makes a maximum uplink data throughput rate of a single cell achieve at 5.76 Mbit/s, which greatly enhances data service bearing capability and spectrum efficiency of the uplinks.
In the WCDMA R11 release, a TTI alignment between CELL-FACH users and cell-dedicated (CELL-DCH for short) users (TTI alignment between CELL-FACH UEs and CELL-DCH UEs) technology is introduced into properties of a enhanced cell forward access channel (CELL-FACH for short). The main spirit of this technology is to perform an alignment transmission for data block uplink subframes of the CELL-FACH users and the CELL-DCH users, so as to reduce interference between the CELL-FACH users and CELL-DCH users, thereby increasing cell throughput. In fact, this technology is a realization and an application of time-division multiple scheduling (TDM scheduling for short) under the CELL-FACH.
In the present universal mobile telecommunications system (UMTS for short) network, a market penetration rate of smartphones is becoming higher and higher, an uplink interference problem gradually emerges with the rapid growth of an amount of network data processing. Since the UMTS is a self-interference system, the uplink interference mainly results from mutual interferences among users, as proved by simulations and theoretical analysis, the TDM scheduling performed on the uplink transmission may produce large suppressions to interferences among users. Therefore, the TDM scheduling may not only be applied to CELL-FACH state, but also be extended to the CELL-DCH state in the future.
In prior art, information bits carried in an enhanced dedicated channel absolute grant channel (E-AGCH for short) include an absolute grant value of 5 bits and an absolute grant scope of 1 bit.
When a 2 ms enhanced dedicated channel (E-DCH for short) TTI is adopted, a timing setting for an absolute grant (AG for short) from being received till becoming effective is as follow: E-DCH control information (namely, AG) firstly received by a user equipment (UE for short) on the jth subframe of an E-AGCH frame in the ith system frame number (SFN for short), is corresponding to the tth subframe of an E-DCH dedicated physical data channel (E-DPDCH for short) in the (i+s)th SFN.
Configuring two E-DCH radio network temporary identifiers (E-RNTI for short) for each UE is supported in the present protocol, where a primary E-RNTI (P-E-RNTI) is an exclusive identification for each UE, theoretically, one-to-many control can be realized by configuring the same secondary E-RNTI (S-E-RNTI for short), however, the S-E-RNTI can neither be used for a process deactivation nor be used for per HARQ activation.
In the process of realizing the present invention, the inventors find that: the operation of activating and/or deactivating a process of a group cannot be performed in the prior art, in a per HARQ scheduling system, the usage amount of AGs re too big, resulting in large consume of downlink code resources, thereby affecting the downlink throughput.

Step 501, when a RNC receives a capability, which is reported by a UE, of the UE to support receiving an absolute grant which is identified as a first E-RNTI during an uplink enhanced dedicated channel operation, the RNC transmits uplink enhanced dedicated channel configuration information of the UE to a base station via a first message.
Where, the uplink enhanced dedicated channel configuration information of the UE includes information such as a frame offset of an uplink enhanced dedicated channel supported by the UE.
Specifically, the first message may be a radio link establishment message, a radio link adding message or a radio link reconfiguration message and etc.
Step 502, the base station, configures an E-RNTI for the UE according to current control reference information, and the base station notifies the E-RNTI configured by the base station for the UE to the RNC via a second message.
Specifically, the E-RNTI configured by the base station for the UE may include a first E-RNTI and a primary E-RNTI; or, the E-RNTI configured by the base station for the UE may include a first E-RNTI, a primary E-RNTI and a secondary E-RNTI.
Where, a first E-RNTI is an E-RNTI allocated by the base station to a group to which the UE belongs, the first E-RNTI may be an additional primary E-RNTI, and may also be a group E-RNTI. In this embodiment, the first E-RNTI is common, the base station configures a uniform first E-RNTI for all UEs in the group to which the UE belongs. In this way, all the UEs belonging to one group can be controlled according to the first E-RNTI, and thus the operation of activating or deactivating the process of the group can be achieved, thereby reducing the utilization of E-AGCHs, improving the utilization efficiency of downlink code resources, and preventing the downlink throughput from being limited.
Where, the current control reference information includes any one or a combination of: a rate of the UE, a data block of the UE, a process number allocated to the UE, group information corresponding to the UE and current process usage situation of a cell.
Specifically, the second message may be a radio link establishment response message, a radio link adding response message, a radio link reconfiguration response message or a radio link parameter updating message and etc.

Where, the third message may be an RRC message such as a radio bearer establishment message, a radio bearer reconfiguration message and an RRC connection establishment message.
Step 504, the base station selects an E-RNTI according to current control demand, and transmits an absolute grant which is identified as the selected E-RNTI to the UE through the first channel.
Specifically, if the current control demand is single control, then the base station selects the primary E-RNTI and transmits an absolute grant which is identified as the primary E-RNTI to the UE through the first channel; or, if the current control demand is group control, then the base station selects the first E-RNTI and transmits an absolute grant which is identified as the first E-RNTI to the UE through the first channel.
Hereinafter, in this embodiment, after step 504, if the base station needs to change the first E-RNTI of the UE, then the base station transmits an updated first E-RNTI to the RNC via the second message, and notifies the RNC to perform an alternation of the first E-RNTI. Then, the RNC will transmit the updated first E-RNTI to the UE via the third message.
In this embodiment, in step 501, after the RNC transmits the uplink enhanced dedicated channel configuration information of the UE to the base station via the first message, the base station may notify the 2 milliseconds HARQ process usage information to the RNC via the second message. Where, the specific process usage information may be that each process is activated or deactivated, or whether each process is a zero grant or not.
