Description

Multi-queue transmission method and device for high-speed downlink packet access medium access control

technical field

The present invention relates to HSDPA (High Speed Downlink Packet Access, high-speed downlink packet access) technology, in particular to a multi-queue transmission method of MAC-hs (Media Access Control for HSDPA, high-speed downlink packet access media access control) in the HSDPA system and a device for applying the method.

Background technique

In order to meet the needs of the rapid growth of wireless data services, 3GPP (3rd Generation Partnership Project, third generation cooperation organization) R5 (Release 5) specification introduced HSDPA technology. By introducing HS-DSCH (High Speed Downlink Shared Channel, high-speed downlink shared channel), HSDPA adopts AMC (Adaptive Modulation Coding, adaptive modulation coding), HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat request), high-order modulation and other technologies , adding a MAC-hs entity on the side of UTRAN (Universal mobile telecommunications system Terrestrial Radio Access Network, universal mobile telecommunications system terrestrial radio access network), which greatly increases the peak rate of downlink data.

On the UTRAN side, the MAC-hs entity in the base station establishes a priority queue for each UE (User Equipment, user terminal) through signaling, and the MAC-hs SDU (Service Data Unit, service data unit) of the UE enters different priority queue. MAC-hs SDU is MAC-d (MAC entity handling dedicated channels, MAC entity handling dedicated channel) PDU, MAC-d PDU is transmitted from RNC (Redio Network Controller, radio network controller) to the priority queue of the base station, Used to form a MAC-hs PDU. The base station scheduler determines the block size of the MAC-hs PDU according to the channel quality information RTBS (Recommended Transport Block Size) fed back from the UE to the base station, and forms the MAC-hs SDU in the priority queue into a MAC-hs PDU, which is determined by HARQ Entity sent to UE.

In the prior art, although a user can have multiple priority queues, the scheduler only schedules the MAC-hs SDUs in one priority queue of the user in the same TTI, and the MAC in one priority queue -hs SDUs form MAC-hs PDUs. The amount of data in each priority queue of the user may be uneven. If the amount of data in a higher priority queue being scheduled is small, the MAC-hs PDU composed of MAC-hs SDUs in the priority queue will be Will be much smaller than the block size that can be transferred. Since there can only be one MAC-hs PDU in the same TTI (Transmission Time Interval, transmission time interval) for a user, when MAC-hs schedules air interface resources, it can only allocate resources for the priority queue with a small amount of data , resulting in a waste of air interface resources.

Contents of the invention

Detailed ways

In the prior art, the MAC-hs entity on the UTRAN side distributes the MAC-hs SDUs from the upper layer to different priority queues according to their priorities, and only transmits the MAC-hs SDUs in one priority queue in each MAC-hs PDU. hs SDU. The upper-layer protocol outputs MAC-hs SDUs to the MAC-hs entity in order, and the UE side also needs to submit MAC-hs SDUs to the upper-layer protocol in the same order to achieve transparent transmission. However, in the process of transmitting MAC-hs PDU, it cannot ensure that MAC-hs SDU reaches UE in order. In the MAC-hs entity on the UE side, there is a reordering queue corresponding to each priority queue on the UTRAN side, and the MAC-hs SDU in the received MAC-hs PDU is output to the corresponding reordering queue. After sorting, output to the upper layer protocol.

In order to be able to identify the reordering queue to which the MAC-hs SDU belongs at the UE side, the MAC-hs PDU in the prior art adopts the frame structure shown in FIG. 1 . A MAC-hs PDU includes MAC-hs header information and one or more MAC-hs SDUs as payload, as well as possible padding bytes. The MAC-hs header information includes VF (Version Flag, version identifier) field, queue ID (QID, Queue Identifier), TSN (Transmission Sequence Number, transmission sequence number) field and one or more SID (Size index identifier, MAC -hs SDU or MAC-d PDU size indication) field, N field and F field.

In the MAC-hs header information in Figure 1, the VF field is set to 0, and this version is reserved; the queue ID field indicates the ID of the priority queue to which the carried MAC-hs SDU belongs or, because the ID of the priority queue is related to the receiving The ID of the terminal reordering queue, the length is 3bit (bit); the TSN field indicates the transmission sequence ID of this MAC-hs PDU on the HS-DSCH (High Speed Downlink Shared Channel, High Speed Downlink Shared Channel) channel, which is used for reordering and Sequential delivery is supported, and the length is 6 bits; the SID field indicates the size of each SDU in a continuous MAC-hs SDUs set, and the relationship between the size of each MAC-hs SDU and the SID is configured by the RRC (Radio Resource Control, radio resource control) high layer, and for Each priority queue is independent; the N field indicates the length of the continuous SDUs set with the same size; the F field indicates whether there are other SID fields behind, and the length is 1 bit.

It can be seen that the UE receiving the MAC-hs PDU can know which reordering queue the MAC-hs SDU carried in it should be put into from the queue ID field in its header information; and in the same reordering queue, the UE can learn from The TSN field knows the correct sequence of MAC-hs SDUs in the queue, so that the sequence delivery function of the upper layer protocol can be realized.

In the present invention, when the amount of data in the high-priority queue is less than the transmission block size determined according to the channel quality during a certain transmission, in order to make full use of the transmission capability of the air interface, the base station can be made to perform the MAC-hs SDU of the next priority queue scheduling. At the same time, the UTRAN side needs to notify the UE which reordering queue the MAC-hs SDU carried in its MAC-hsPDU belongs to. Since the reordering queue on the UE side has a one-to-one correspondence with the priority queue on the UTRAN side, the queue to which the MAC-hs SDU belongs can either be a priority queue or a reordering queue. In the present invention, the MAC-hs SDU The queues to which they belong are collectively referred to as priority queues or reordering queues.

The flow of the MAC-hs multi-queue transmission method in the present invention on the UTRAN side is shown in FIG. 2 . In step S210, the channel quality information fed back by the UE is received. The channel quality information fed back by the UE to the UTRAN side can provide a basis for the base station scheduler to allocate the specific size of the MAC-hs PDU, such as RTBS.

In step S220, the block size of the MAC-hs PDU for this transmission is determined according to the channel quality information fed back by the UE.

In step S230, the base station scheduler schedules the priority queue with the highest priority currently to be transmitted MAC-hs SDU. Steps S210 to S230 are the same as in the prior art.

In step S240, it is judged whether the data volume of the scheduled MAC-hs SDU reaches the capacity that this transmission can carry, if yes, execute step S250; if not, turn to step S230, and continue to schedule the next non-empty priority queue .

The capacity that can be carried by this transmission is the amount of data carried in the MAC-hs PDU. When the size of the MAC-hs PDU block indicated by the channel quality fed back by the UE is the same, the capacity that can be carried by this transmission may vary depending on the size of the MAC-hs PDU. The frame format of the PDU and the data volume of the header information are different.

In step S250, the scheduled MAC-hs SDUs are combined into a MAC-hs PDU, and the queue to which the MAC-hs SDUs in the payload belong is indicated in the MAC-hs PDU.

Corresponding to different MAC-hs PDU frame formats, there are many ways to indicate the queues of the MAC-hs SDUs included in the MAC-hs PDU. For example, one of the most direct ways is to separate each MAC-hs SDU Indicates the queue it belongs to. Considering the header information overhead of the MAC-hs PDU and the efficiency of composing and parsing the MAC-hs PDU, the present invention recommends using the MAC-hs PDU header information format shown in Figure 3 to indicate the queue to which the MAC-hs SDU belongs.

In the MAC-hs header information in Figure 3, fields such as QID, TSN, SID, N, and F are used to describe each queue, and their meaning and arrangement are the same as those in the prior art, that is, starting with the QID field, followed by the TSN field , SID field, N field and F field. The F field indicates whether there are other MAC-hs SDUs of the queue after the MAC-hs SDU corresponding to the current SID by setting and resetting. The last F field of each queue should be reset.

Add the QF field after the last F field of each queue. Its function is similar to the F field. When the QF field is set, it indicates that in the payload of the MAC-hs PDU, the MAC-hs SDU of the current queue has reached this point in this transmission. End, followed by MAC-hs SDU in another queue; when the QF field is reset, it means that the MAC-hs SDU of the current queue ends in this transmission, and the current queue is the last queue scheduled in this transmission. When the QF field is set, the QF field in the header information of the MAC-hs PDU is followed by the above description fields of the next scheduled queue.

When the base station MAC-hs entity generates the MAC-hs entity to generate the MAC-hs PDU according to the scheduled MAC-hs SDU, it first fills in the QID ₁ and TSN ₁ fields with the queue ID of the first scheduled queue, the current transmission MAC-hs PDU for the transmission sequence number of the first queue to be scheduled, and then fill in the fields of SID ₁₁ , N ₁₁ , F ₁₁ to SID _1m , N _1m , and F _1m in turn for the MAC in the first queue - hsSDU description information, where the F _1m field is reset, indicating the last MAC-hsSDU of the first queue. When a MAC-hs PDU includes MAC-hs SDUs of multiple queues, the QF field after the F _1m field is set, and the QID ₂ , TSN ₂ fields of the second queue and the subsequent SID ₂₁ , N ₂₁ , F ₂₁ to SID _2n , N _2n , F _2n fields. F _{The 2n} field is reset, if the MAC-hsPDU only carries MAC-hs SDUs in two queues, the subsequent QF field is reset; otherwise, the subsequent QF field is set, and the description of the third queue is added field.

In step S260, downlink transmit the generated MAC-hs PDU.

The above-mentioned MAC-hs transmission method of the present invention is not only applicable to a single-carrier TDD (Time Division Duplex, time division duplex) HSDPA system, but also applicable to a multi-carrier TDD HSDPA system. For the single-carrier TDD HSDPA system specified in R5, the HARQ entity used for MAC-hs PDU transmission has 8 HARQ processes, each HARQ process can send MAC-hs PDU, and each MAC-hs PDU carries its own TSN, used for reordering at the receiving end. In this way, to realize continuous transmission of all HARQ processes, the maximum value of TSN should not be less than 8.

At the same time, the maximum value of TSN is also related to the size of the sending window and/or receiving window. The UE performs sliding processing on the receiving window based on the TSN. If the TSN falls outside the receiving window range of the UE, the UE will perform related operations according to whether the TSN falls behind or in front of the window. If the TSN falls in front of the window, the UE will Before sliding the receiving window, the UE will no longer receive those TSNs that fall behind the receiving window. If the TSN falls behind the window, the UE will no longer receive the TSN; for the UTRAN side, if the retransmitted TSN falls outside the sending window range, the UTRAN side will stop retransmitting the data frame; it can be seen that MAC-hs PDU The carried TSN is an important factor affecting the normal communication between UE and UTRAN side. The UE is responsible for receiving the MAC-hs PDU, and the base station is responsible for sending the MAC-hs PDU. Generally, the size of the sending window and the receiving window are the same.

The size of the sending window limits the maximum value of the base station's continuous transmission of TSN, thereby limiting the ability of the base station to utilize the bandwidth of the air interface. In the current R5 specification, the maximum sending window size is 32, which means that the base station can continuously send MAC-hs PDUs with TSNs from 0 to 31 without waiting for the receiving end to confirm. In order to prevent wrapping and other reasons, the length of the TSN field in the current specification is 6 bits, and the maximum supported TSN is 63, which can meet the requirements of the single-carrier HSDPA system.

The peak rate supported by a single carrier cannot meet future high-speed service requirements. In a multi-carrier TDD HSDPA system, the cell needs to support single-carrier and multi-carrier users at the same time. The frame structure of the uplink and downlink physical shared control channel of multi-carrier TDD HSDPA cannot be easily changed. MAC-hs SDUs are assigned to different carriers, and each carrier performs coding mapping, modulation and transmission independently. For the UE, it is necessary to have the ability to receive data of multiple carriers at the same time. After each carrier is decoded independently, the MAC-hs on the UE side performs the combination. In this way, each carrier has a HARQ entity to ensure the correct reception of the MAC-hs PDU on the carrier.

In the multi-carrier TDD HSDPA system, the HARQ entity on each carrier transmits and receives independently. Therefore, when all HARQ processes between the base station and the UE are continuously sent in a multi-carrier system, the number of MAC-hs PDUs sent is the product of the number of carriers used simultaneously during transmission and the number of HARQ processes on one carrier. In this way, the range of each queue TSN is at least 0 to the product minus 1, so as to ensure that the receiving end can correctly reorder the received MAC-hs SDUs. In order to prevent wrapping, the TSN maximum value is usually set to twice the product minus 1. At the same time, the bit width of the TSN field of each queue in the MAC-hs PDU frame format should also match the set TSN maximum value.

For example, in a general TD-SCDMA (Time Division Synchronous Code Division Multiple Access, time division synchronous code division multiple access) cell base station and UE, the number of simultaneous transmission carriers is 6, and the number of HARQ processes also increases with the number of carriers, which can reach 48 processes, if all processes send continuously, the range of TSN can reach 0 to 47. At the same time, the air interface bandwidth of the multi-carrier HSDPA system is much higher than that of the single-carrier system, and the range of the transmission window is correspondingly expanded to allow the base station to fully utilize the air interface bandwidth. The value can be set to be proportional to the number of carriers, that is, 32×6=192.

It can be seen from the above that the original TSN range from 0 to 63 makes reordering at the receiving end very difficult. The maximum value of TSN is generally twice the size of the maximum sending window minus 1, that is, 383. In the header information of the MAC-hs PDU, when the bit width of the TSN field is 9 bits, it can support its maximum value of 383. However, if the TSN length is too long, air interface resources will be occupied, so the present invention recommends setting the bit width of the TSN field to 9 bits.

In addition, since the air interface frame format in the present invention is different from the frame format in the existing specification, and the VF field in the frame format is 0 and this version is reserved, the MAC-hs header information in the air interface frame format in the present invention can be The VF field is set to 1, indicating multi-carrier HSDPA, so that the multi-carrier UE can confirm that the serving cell can provide multi-carrier services through the identification.

In summary, the modification or addition of the MAC-hs PDU air interface frame format recommended in the present invention to the existing specifications is shown in the following table:

Logo Add/Modify Location meaning VF Revise very beginning TSN Modified, increased to 9 bit located behind the QID Ensuring that the UE can obtain the maximum downlink rate by increasing the bit width

QF Add behind the F logo Whether there is other queue information behind the flag; 1 means there is other queue information behind it, and 0 means there is no other queue information QID2, TSN2, etc. add new Located behind the QF logo Identify the MAC-hs SDU information of other queues (invalid when QF is 0)

On the UE side, when the UE receives the MAC-hs PDU generated in the above air interface frame format, it can analyze it according to the following steps:

a. The UE reads information such as QID ₁ , TSN ₁ , and SID ₁ in turn, as the basis for parsing the MAC-hsSDU in the queue; after the SID field is obtained, enter step b;

b. The UE reads the F field. If the F field is set, it means that all the SID fields of the queue are over, and enters step c; if the F field is reset, continue to read the information of the next SID field of the queue;

c. Read the QF field after the F field. If the QF field is set, it means that there is other queue MAC-hs SDU information in the future, then go to step a; if the QF field is reset, it means that there is no other queue information in the future, go to step d;

d. UE starts to analyze the MAC-hs SDUs of each queue according to the load information of the obtained MAC-hs PDUs, and distributes them to the corresponding reordering queues.

The structure schematic diagram of MAC-hs multi-queue transmission device of the present invention is shown in Figure 4, and priority queue module 410 is connected with scheduling module 420 and PDU generating module 430 respectively; Scheduling module 410 is connected with PDU generating module 420 and channel quality respectively Module 440 ; the PDU generation module 420 is connected to the transmission module 430 .

The priority queue module 410 includes at least one priority queue corresponding to a certain UE, and each priority queue stores MAC-hs SDUs to be sent with the same priority.

The channel quality module 450 determines the block size of the MAC-hs PDU transmitted this time according to the channel quality information received from the UE, and outputs the determined block size to the scheduling module 420.

The scheduling module 420 decides which MAC-hs SDUs in the priority queue module 410 are used for this transmission. The scheduling module 420 first schedules the current non-empty queue with the highest priority. When the data volume of the higher priority queue cannot meet the capacity of this transmission, the scheduling module 420 schedules the lower non-empty priority queue. When the scheduled MAC-hs SDU can satisfy this transmission, the scheduling module 420 notifies the PDU generation module 430 of the MAC-hs SDU for this transmission. The scheduling module 420 calculates the capacity that this transmission can carry according to the block size input from the channel quality module 450 .

The PDU generating module 430 takes out the MAC-hs SDU scheduled by the scheduling module 420 from the priority queue module 410, forms it into a MAC-hs PDU for this transmission, and indicates in the MAC-hs PDU the queue to which the MAC-hs SDU belongs . For the manner in which the PDU generation module 430 indicates the queue to which the MAC-hs SDU belongs and the frame format used to generate the MAC-hs PDU, please refer to the foregoing description, and will not be repeated here.

The PDU generation module 430 outputs the generated MAC-hs PDU to the transmission module 440, and the transmission module 440 downlink transmits the MAC-hs PDU to the corresponding UE.

The present invention adds a QF field to the header information of the MAC-hs PDU to support the MAC-hs to carry multiple queues of MAC-hs SDUs in one transmission, and improves the efficiency of air interface resources while providing maximum compatibility with existing specifications. Utilization, especially for multi-carrier HSDPA systems. In addition, the present invention expands the bit width of the TSN field in the MAC-hs PDU header information, preventing the reordering problem at the receiving end that may be caused by the too small maximum value of TSN supported by the existing specification under multi-carrier HSDPA.

The embodiments of the present invention described above are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
