Description

A kind of report method of schedule information and system

Technical field

The present invention relates to the reporting of scheduling information (SI) technology in wireless communication system, relate in particular to a kind of report method and system that adopts the schedule information of High Speed Packet Access in the time that the enterprising line number of two carrier waves is reportedly sent.

Background technology

In existing system, schedule information is the reference information of dispatching as most crucial Node B.Here Node B is base station node B.Schedule information method in existing system is specific as follows:

Schedule information is positioned at the afterbody of the protocol Data Unit of the medium access control entity of processing enhancement dedicated channel.Schedule information is used to observe the required system resource total amount of terminal to Node B with a better visual angle, and the actual system resource total amount that maybe can use that uses of terminal.Schedule information sends to Node B by terminal.The content of schedule information is the renewal value of buffer status, and this value is the value that data new after enhanced transport format Resource selection process transmit.Schedule information territory comprises: the buffer status territory of the logic channel of the limit priority of total enhancement type special channel buffer status territory of the Logic Channel Identifier territory of the limit priority of 4 bits, 5 bits, 4 bits and the terminal power clear space territory of 5 bits, the form of schedule information as shown in Figure 1, is made up of these four territories.Wherein, least significant bit is the rightmost bit in Fig. 1; Highest significant position is the leftmost bit in Fig. 1.Here, in binary number, highest significant position is the highest summation of weighted bits, is usually located at the leftmost side of binary number; Least significant bit is lowest weighted position, is usually located at the rightmost side of binary number.Below each territory is set forth respectively.

For the Logic Channel Identifier territory of limit priority, the Logic Channel Identifier territory of limit priority identifies clearly: the highest priority logical channel of data available.If multiple logic channels all in limit priority, the mark of that logic channel so corresponding report high level cache being taken.The length in the Logic Channel Identifier territory of limit priority is 4 bits.

For total enhancement type special channel buffer status territory, total enhancement type special channel buffer status domain identifier goes out: radio resource control layer requires the total amount of the data available of all logic channels of leap of report.That is to say, total enhancement type special channel buffer status territory is used in reference to and illustrates: the data total amount at wireless chain control layer for transmitting and retransmitting, and take byte as digit.The length in total enhancement type special channel buffer status territory is 5 bits.

If configured the medium access control entity of processing enhancement dedicated channel, as medium access control entity i (MAC-i)/medium access control entity is (MAC-is), this territory also comprises the data total amount that can be used in MAC-i/MAC-is segmentation entity sends so.When the radio link control entity of medium access control entity and affirmation mode is associated, this territory also comprise by be sent out the data of control protocol data cell, and be also included in the data of the wireless link control protocol data cell outside wireless link control send window.In addition sent, but do not confirmed by opposite end entity that in the negative the data of the wireless link control protocol data cell of (NACK) should not be comprised in this territory.

For the buffer status territory of the logic channel of limit priority, the buffer status territory of the logic channel of limit priority indicates: by the amount of available data on the logic channel of the Logic Channel Identifier territory indication of limit priority.The length in the buffer status territory of the logic channel of limit priority is 4 bits.

For terminal power clear space territory, terminal power clear space territory indicates: the ratio of the code power of terminal maximum transmit power and corresponding Dedicated Physical Control Channel.The length in terminal power clear space territory is 5 bits.

For the rule that arranges of existing schedule information, this rule request: in schedule information, when total enhancement type special channel buffer status territory is designated as index 0, when 0 byte, the buffer status territory of the logic channel of limit priority must also be designated as index 0.

Along with technical development, two ZAP wish to be introduced into existing system, adopt this technology to make terminal on two carrier waves, to send data, thereby uplink data rate is doubled.But introduce after two ZAP, still adopt the rule that arranges of existing schedule information, and end side adopts the schedule information obtaining according to this existing rule to realize to report, in the time of the Node B resolution scheduling information of opposite side, will cause following problem:

If adopt the schedule information obtaining according to existing rule, terminal power clear space territory in schedule information indicates so: the ratio of the code power of terminal maximum transmit power and corresponding Dedicated Physical Control Channel, and the code power of the Dedicated Physical Control Channel of each carrier wave is different.Under two ZAP, terminal power clear space territory in schedule information, need to explicitly point out is the code power for the Dedicated Physical Control Channel of which carrier wave in two carrier waves, Node B is just meaningful in the time of resolution scheduling information like this, otherwise Node B cannot know that this ratio of terminal power clear space territory indication is the ratio corresponding to which carrier wave.

Visible, adopt the schedule information obtaining according to existing rule, although there is the information in terminal power clear space territory, but, Node B still cannot accurately be learnt the concrete power headroom situation on corresponding each carrier wave, causes in fact Node B cannot use more terminal power headrooms, carries out higher rate, more high-power data transmission, that is to say, the speed that causes terminal to send data cannot promote; Or in fact Node B possible errors ground uses terminal power headrooms, carries out higher rate, more high-power data transmission, that is to say, the speed that causes terminal to send data is promoted by mistake.No matter any situation, Node B all cannot make full use of system resource and terminal power, to such an extent as to cannot provide the optimal scheduling under coupling current network performance and terminal disturbed condition, under extreme case, will cause power ramp unreasonable, disturb too highly, user capacity reduces, and terminal sends that data effective speeds reduces and the catastrophic effect such as go offline.

At present, in the urgent need to a kind of novel reporting of scheduling information (SI) scheme, can explicitly point out: the terminal power clear space arranging in the terminal power clear space territory of schedule information is the terminal power clear space for which carrier wave in two carrier waves.Like this, after reporting scheduling information, Node B is in the time of resolution scheduling information, this ratio that just can know the indication of terminal power clear space territory is the ratio corresponding to which carrier wave, thereby can observe the required system resource total amount of terminal with a better visual angle, and the actual system resource total amount that maybe can use that uses of terminal, realize better scheduling of resource.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of report method and system of schedule information, can realize reporting of schedule information, and this schedule information can explicitly point out: the terminal power clear space territory in schedule information is the terminal power clear space for which carrier wave in two carrier waves, so that the specific aim of Node B is resolved, realize better scheduling of resource.

Step 301, in schedule information, the thresholding in the total enhancement type special channel buffer status territory of terminal is set to: radio resource control layer requires the total amount of the data available of all logic channels of leap of report.

Step 302, in schedule information, in the time that the thresholding in total enhancement type special channel buffer status territory is non-index 0, the thresholding in the buffer status territory of the logic channel of terminal limit priority is set to: by the amount of available data on the logic channel of the Logic Channel Identifier territory indication of limit priority.

Step 303, in schedule information, terminal terminal power clear space territory is set to: the terminal power clear space of carrier wave two.

Here, terminal also comprises reporting of scheduling information (SI) to after base station: the process that resolve the schedule information of receiving base station, and this process specifically comprises:

Resolve the schedule information of receiving base station, be set to index 0 if parse the thresholding in total enhancement type special channel buffer status territory, and the thresholding in the buffer status territory of the logic channel of limit priority is set to non-index 0, the terminal power clear space that current terminal power clear space is carrier wave one is determined in base station; Otherwise the terminal power clear space that current terminal power clear space is carrier wave two is determined in base station.

Here,, for the terminal power clear space of above carrier wave one, the terminal power clear space of carrier wave one is specially: the ratio of the code power of corresponding Dedicated Physical Control Channel on terminal limit transmitted power and carrier wave one.Wherein, terminal limit transmitted power is: the maximum transmit power of terminal.

For the terminal power clear space of above carrier wave two, the terminal power clear space of carrier wave two is specially: the ratio of the code power of corresponding Dedicated Physical Control Channel on terminal limit transmitted power and carrier wave two.

For the non-index 0 relating to above, non-index 0 is specially: length is in all values in buffer status territory of the logic channel of the limit priority of 4 bits, and value is any value of non-index 0.In fact the Node B repeatedly relating in literary composition is exactly base station, does not repeat here.

In sum, the present invention mainly comprises following content:

In schedule information of the present invention, by total enhancement type special channel buffer status territory, the buffer status territory of the logic channel of associating limit priority, indicate the terminal power clear space on one carrier wave in two carrier waves, observe the required system resource total amount of terminal with a better visual angle to Node B so that follow-up, and the actual system resource total amount that maybe can use that uses of terminal.One carrier wave in two carrier waves can be designated as to carrier wave one, another one carrier wave remaining in two carrier waves is designated as carrier wave two.

For the rule that arranges of schedule information of the present invention, rule request: in schedule information, total enhancement type special channel buffer status territory is designated as index 0, and when the buffer status territory of the logic channel of limit priority is designated as non-index 0 and is worth, terminal power clear space territory refers to: the terminal power clear space on carrier wave one; Otherwise terminal power clear space territory refers to the terminal power clear space on carrier wave two.

Rule is set obtains after schedule information based on this, terminal is by this reporting of scheduling information (SI) to Node B, and Node B is received after this schedule information afterwards, can resolve, and below sets forth respectively.
