Description

Triggering of scheduling information and carrier activation control method and device

technical field

The present invention relates to a triggering mechanism of scheduling information in a wireless communication system, in particular to a triggering method and device for scheduling information when using high-speed packet access technology to transmit data on dual carriers in a wireless communication system, and a carrier Activation control methods and apparatus.

Background technique

In the existing system, scheduling information (SI, Scheduling Information) is used as reference information for Node B to perform scheduling. The scheduling information is located at the end of the protocol data unit of the Media Access Control (MAC, Media Access Control) entity that processes the Enhanced Dedicated Channel (E-DCH, Enhanced Dedicated Channel). The scheduling information is used to give the serving Node B a better perspective to observe the total amount of system resources required by the user terminal and the total amount of system resources actually used or available by the user terminal.

The scheduling information is sent by the user terminal to the Node B, and its content is the buffer status update value of the new data transmission after the enhanced transmission format set selection process. Fig. 1 is a schematic diagram of the scheduling information format in the prior art. As shown in Fig. 1, the scheduling information frame structure includes the following domains:

1) The highest priority logical channel identifier. The "Highest Priority Logical Channel Identification" field unambiguously identifies the highest priority logical channel for which data is available. If multiple logical channels are in the highest priority, then the identity of the logical channel corresponding to the highest buffer occupancy will be reported. The "Highest Priority Logical Channel Identifier" field has a length of 4 bits.

2) Enhanced Dedicated Channel Total Buffer State (TEBS, the Total E-DCH Buffer State). The "Enhanced Dedicated Channel Total Buffer Status" field identifies the total amount of data available across all logical channels that the RRC layer is required to report. The "Enhanced Dedicated Channel Total Buffer Status" field indicates the total amount of data used for transmission and retransmission at the radio link control layer, in bytes. If a media access control entity handling enhanced dedicated channels such as MAC-i/is (media access control entity i/media access control entity is) is configured, then this field also includes the MAC-i/is segment entity The total amount of data available for sending. When the MAC entity is associated with an RLC entity in acknowledged mode, this field also includes the data of the control protocol data unit to be sent, and also includes the radio link control entity outside the RLC sending window. The data of the control protocol data unit. In addition, the data of RLC PDUs that have been sent but not non-acknowledged (NACK) by the peer entity shall not be included in this field. The "Enhanced Dedicated Channel Total Buffer Status" field has a length of 5 bits.

3) Buffer status of the highest priority logical channel. The "Buffer Status of Highest Priority Logical Channel" field indicates the amount of data available on the logical channel indicated by the "Highest Priority Logical Channel Identification" field. The "Buffer Status of Highest Priority Logical Channel" field has a length of 4 bits.

4) Terminal Power Headroom (UPH). The "terminal power headroom" field indicates the ratio of the maximum transmit power of the user terminal to the code power of the corresponding dedicated physical control channel. The "Terminal Power Headroom" field has a length of 5 bits.

The format of the scheduling information frame structure is shown in Figure 1, which consists of the four fields described above. Wherein, the least significant bit is the rightmost bit in FIG. 1 ; the most significant bit is the leftmost bit in FIG. 1 .

The triggering of scheduling information in the existing system is divided into the following two scenarios:

Scenario 1: Serving Grant (SG, Serving Grant) is equal to 0, or all Hybrid Automatic Repeat request (HARQ, Hybrid Automatic Repeat request) processes are deactivated.

Scenario 2: SG is not equal to 0 and at least one HARQ process is activated.

For Scenario 1, there are two event triggers and one periodic trigger. One case event is that the buffer becomes non-empty, and the other case event is that the serving cell has changed and is not in the previous link set. The periodic triggering of the scheduling information is controlled by a timer (T-SING, Timer Scheduling Information-"Zero_Grant") whose scheduling information is zero grant, and the T-SING is configured to the MAC by the radio resource controller (RRC, RadioResource Controller). Once the scene one condition occurs and TEBS is greater than 0, T-SING will be started. When the T-SING times out, the transmission of new scheduling information will be triggered. Once scene two occurs, the T-SING timer is stopped and reset. Once the scheduling information is triggered, T-SIG will be restarted.

For Scenario 2, there are two event triggers and one periodic trigger. One case event is that there are too few SGs, and the other case event is that the serving cell has changed and is not in the previous link set. The periodic triggering of the scheduling information is controlled by a timer (T-SIG, Timer Scheduling Information-different from "Zero_Grant") whose scheduling information is not zero grant, and the T-SIG is configured to the MAC by the RRC. Once the conditions of Scenario 2 occur, T-SIG will be activated. When the T-SIG times out, the transmission of new scheduling information will be triggered. As soon as the scenario occurs, the T-SIG timer is stopped and reset. Once the scheduling information is triggered, T-SIG will be restarted.

When using the dual-carrier technology (this technology enables the user terminal to transmit data on two carriers, thereby doubling the uplink data rate), the current industry has reached a consensus on the scheduling information periodic trigger mechanism in the prior art, That is to configure two sets of trigger timers, that is, each carrier has a set of timers: T-SING and T-SIG. T_SIG and T_SING are independently configured by the network side. The T_SIGs of both carriers share the same network configuration value. The T_SING of the two carriers share the same network configuration value. But the value between T_SIG and T_SING can be different.

The estimation of T_SING is based on the carrier, and the scheduling information is sent on the carrier that triggers the scheduling information. T_SIG activation is based on carrier characteristics, that is, as long as the SG on that carrier is not equal to 0 and at least one process is active on that carrier, the T_SIG corresponding to this carrier is activated. When the T_SIG times out, if two T_SIGs are running, the scheduling information will be sent on both carriers; otherwise, the scheduling information will only be sent on the carrier that timed out. If scenario one is met on a certain carrier, T_SIG will be stopped or reset.

The scheduling information event trigger is based on carrier characteristics, and the scheduling information is only sent on the carrier that triggers the SI information.

When using dual-carrier technology for dual-cell enhanced dedicated channel operation, the Node B can use the High-Speed Shared Control Channel (HS-SCCH, High-Speed Shared Physical Control Channel) command to activate and deactivate the secondary uplink carrier. For example, a Node B can activate or deactivate a secondary carrier based on over-the-air interference or resource availability.

Poor radio conditions may cause the user terminal to increase the power of its dedicated physical control channel. As a result, both carriers will have very little power to transmit data. Poor radio conditions can even lead to power-limited situations, resulting in reduced throughput. The network side may be aware that the user terminal is experiencing poor radio conditions, but not to what extent. In this case, the UE power headroom information can help the Node B to decide whether to use deactivation to help the UE leave the power-limited state and make full use of its resources.

When the user terminal is experiencing good radio conditions, the terminal power headroom value can help the Node B decide whether to activate the secondary carrier, thereby improving the throughput of the user terminal.

The current scheduling information trigger mechanism is mainly based on the buffer size and SG. Periodic triggering is optionally configured by the network. The network may not need to obtain periodic scheduling information, but only needs the value of the terminal power headroom (UPH) in special cases to determine whether to activate the secondary carrier.

This prevents the Node B from making full use of system resources and user terminal power to provide optimal scheduling that matches current network performance and user terminal interference conditions.
