AI Technical Summary

Problems solved by technology

If the sum of the number of time slots that the MS supports for sending and receiving data is an odd number, the existing RTTI technology cannot utilize the maximum sending and receiving capability of the MS, resulting in a waste of some sending and receiving functions
For example, the sum of the number of time slots that an MS supports for sending and receiving is 5 time slots. If RTTI configuration is used, the network assigns the MS to use two time slots for uplink and downlink, so that the sum of the number of time slots for sending and receiving is 4. The maximum limit of 5 is not reached, which wastes the MS's uplink sending capability, and actually limits the uplink bandwidth

Embodiment 1

[0042] Embodiment 1: The mobile station implements uplink scheduling of MTTI TBF

[0043] figure 1 It is a flow chart of the method for scheduling uplink resources provided by the first embodiment of the present invention. This embodiment describes the technical solution for realizing uplink resource scheduling from the side of the mobile station. like figure 1 As shown, the method for scheduling uplink resources in this embodiment includes:

[0044] 11. Receive the uplink single temporary block flow (TBF) resource assignment information sent by the network side, the uplink single TBF resource assignment information includes the uplink time slot information allocated by the network side for the mobile station, and the uplink state identifier corresponding to the uplink time slot (USF), the above-mentioned uplink time slot information includes information about at least one uplink reduced transmission time interval (RTTI) time slot pair and information about at least one upl...

[0052] Embodiment 2: The network side implements uplink scheduling of MTTI TBF

[0053] image 3 It is a flowchart of a method for scheduling uplink resources provided by the second embodiment of the present invention. This embodiment describes the technical solution for realizing uplink resource scheduling from the network side. The method for scheduling uplink resources in this embodiment includes:

[0054] 31. Generate uplink single TBF resource assignment information and send it to the mobile station. The uplink single TBF resource assignment information includes information about the uplink time slot allocated by the network side for the mobile station, and the USF corresponding to the uplink time slot. The information includes information of at least one uplink RTTI time slot pair and information of at least one uplink BTTI time slot.

[0055] 32. Send the above USF in the downlink time slot corresponding to the uplink time slot, which is used to notify the mobile sta...

Embodiment 3

[0060] Embodiment 3: DA uplink scheduling MTTI TBF in BTTI USF mode

[0061] Figure 4A schematic diagram of MTTI TBF radio block allocation operation during DA uplink scheduling in BTTI USF mode provided by the third embodiment of the present invention.

[0062] If the MTTI TBF assignment message received by the MS indicates to use the single BTTI USF mode, for example, there are two USFs for each RTTI time slot pair, indicating that the current MTTI TBF scheduling mode is the BTTI USF mode. In BTTI USF mode, BTTI (20ms) is used as the scheduling period for uplink resource scheduling. Therefore, in BTTI USF mode, the scheduling periods of BTTI radio blocks and RTTI radio blocks are both 20ms.

[0063] If the MS monitors the corresponding USF on the time slot with a lower sequence number in the uplink RTTI time slot pair and the corresponding downlink RTTI time slot pair, the MS can send the RTTI radio block in the first 10ms of the next BTTI radio block period (20ms). For e...

Abstract

The invention relates to a dispatching method, a device and a communication system of uplink resources, wherein the dispatching method of uplink resources comprises the following steps: receiving uplink single TBF resource assignment information sent from a network side, wherein the uplink single TBF resource assignment information comprises the information of an uplink time slot allocated from the network side to a mobile station and the USF corresponding to the uplink time slot, and the information of the uplink time slot comprises the information of at least one uplink RTTI time slot and the information of at least one uplink BTTI time slot; and when the USF is monitored on a downlink time slot corresponding to the uplink time slot, sending uplink BTTI wireless blocks and / or RTTI wireless blocks at the uplink time slot corresponding to the monitored USF or partial or all uplink time slots of which the serial numbers are equal to or greater than the serial number of the corresponding uplink time slot. The embodiment of the invention not only can send BTTI blocks but also can send RTTI blocks in one TBF, thereby improving the flexibility of dispatching of uplink resources.

Description

technical field [0001] The present invention relates to communication technology, in particular to an uplink resource scheduling method, device and communication system. Background technique [0002] In a communication system, a Temporary Block Flow (TBF for short) is a temporary connection established between a mobile station (Mobile Station, MS for short) and a network side, and exists only during data forwarding. The TBF supports unidirectional forwarding of a logical link control (Logical Link Control, LLC for short) packet data unit on a packet physical channel. A Time Division Multiple Access (TDMA) frame in the circuit domain is divided into 8 time slots, and the same time slot allocated by the network side to each TDMA frame of the General Packet Radio Service (GPRS) is called It is a Packet Data Channel (PDCH for short). The TBF allocated by the network side to the MS is equivalent to allocating one or more currently available PDCHs for the MS. Specifically, the n...
