Description

HSPA System Accompanying Channel Allocation Method, Base Station and System

technical field

The invention relates to the field of wireless communication, in particular to a method for allocating accompanying channels in an HSPA system, a base station and a system.

Background technique

HSPA (High Speed Packet Access, High Speed Packet Access) is the collective name of two technologies, HSDPA (High Speed Downlink Packet Access, High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access, High Speed Uplink Packet Access). Adaptive modulation and coding), HARQ (hybrid automatic retransmission), high-order modulation (16QAM) and other technologies, and realize fast scheduling on the base station side, so that it can quickly and adaptively reflect changes in user channels and obtain higher peak user rates and cell data throughput.

Currently, the TD-SCDMA HSDPA system involves five channels, namely:

HS-PDSCH: High-Speed Physical Downlink Shared Channel, high-speed physical downlink shared channel, is an HSDPA service channel, used to carry high-level data of each UE (user equipment);

HS-SICH: High-Speed Shared Information Channel for HS-DSCH high-speed downlink shared channel shared information channel, is the HSDPA uplink control channel, used to carry and HS-DSCH (high-speed downlink shared channel, the corresponding physical channel is HS-PDSCH ) related signaling information, which may include HARQ acknowledgment/denial acknowledgment (ACK/NACK), downlink channel quality indication (CQI);

HS-SCCH: High-Speed Shared Control Channel, high-speed shared control channel, is an HSDPA downlink control channel, used to carry downlink signaling information, these signaling information can include channelization code set, time slot information, modulation mode , transmission block size, HARQ process ID (HARQ ProcessID), redundancy version, new data flag, HS-SCCH cycle sequence number and UE ID, etc.;

UL A-DPCH: HSDPA uplink accompanying channel, used to carry high-level data of each UE (user equipment) and uplink accompanying signaling;

DL A-DPCH: HSDPA downlink accompanying channel, used to carry downlink accompanying signaling, and used for physical layer control (including synchronization and power control) of uplink DPCH.

Among them, HS-DSCH is always accompanied by a downlink DPCH channel and one or more HS-SCCH channels. Each UE needs a downlink DPCH channel to provide SS synchronization commands for the UE uplink DPCH channel and uplink control channel HS-SICH, so as to ensure the synchronization of downlink DPCH, uplink DPCH channel and uplink control channel HS-SICH.

TD-SCDMA HSDPA system capacity is mainly determined by the number of carriers and HS-PDSCH time slots, but the number of access users is restricted by the accompanying channel. The typical configuration of HSDPA system resources can be shown in Figure 1, and the typical configuration of HSPA (including HSDPA and HSUPA) system resources can be shown in Figure 2. It can be seen from Figure 1 and Figure 2 that there are only 6 downlink accompanying channels in the downlink TS6 configuration in the HSDPA system, and only 3 in the HSPA system, that is, regardless of other channel resources, in terms of downlink accompanying channels It can support 6 or 3 users. Obviously, this typical HSPA resource configuration will limit the number of users accessed by a single carrier.

In order to solve this problem, in the current technology and standard, support for the multiplexing function of the downlink accompanying channel is added, which is realized by frame division multiplexing, and its essence is time division multiplexing, that is, the control cycle of L1 is increased. The frame division multiplexing mode of the downlink accompanying channel includes:

2 times frame division multiplexing: multiplexing by 2 downlink accompanying channels, that is, the original L1 control of each TTI (such as 40ms) is adjusted to the L1 control of every 2 TTIs (80ms);

4 times frame division multiplexing: multiplexing by 4 downlink accompanying channels, that is, the original L1 control of each TTI (such as 40ms) is adjusted to the L1 control of every 4 TTIs (160ms).

For the HSDPA system with the resource configuration shown in Figure 1, 2 downlink control channels are configured in the downlink TS6, and the remaining 6 downlink accompanying channels are available. The number of access UEs is shown in Table 1:

Table 1

Although frame division multiplexing can improve the use efficiency of the downlink accompanying channel and increase the number of access users, it will not become the bottleneck of the number of access users in the HSDPA system at first, but it will increase the control period of user L1 (from 1 TTI to 2 or 4 times), the performance of its air interface will decrease accordingly. In the wireless communication system, the control cycle of the physical layer is minimized to improve the performance of the air interface and improve the system efficiency. However, the frame division multiplexing method of the downlink accompanying channel in the existing HSDPA system sacrifices the performance of the air interface in exchange for the maximum interface. The ability to enter the number of users.

Under the urban propagation model, through simulation, when the L1 control cycle is increased from 1 TTI to 2 TTIs, the demodulation threshold of the channel will be deteriorated by 1-2 dB, and when it is increased to 4 TTIs, the demodulation threshold will be deteriorated by 4-5 dB. Regardless of 2 times frame division multiplexing or 4 times frame division multiplexing, the deterioration of the demodulation threshold of the channel will lead to the shrinkage of its coverage capability, and will affect the capacity of the HSDPA system in severe cases.

The frame division multiplexing multiple of the downlink accompanying channel of the existing HSDPA system is set according to the maximum number of access users, and is a fixed setting. For example, according to the multiplexing factor setting of 4 times, the maximum number of users that can be accessed is: 4×the number of downlink accompanying channels. Even in the case of fewer users, the next accompanying channel is allocated after being multiplexed according to the code channel, which will cause multiple users to share the accompanying channel, and many accompanying channel resources are idle, resulting in reduced system performance. It can be seen that there is some irrationality in the existing accompanying channel multiplexing mechanism.

Detailed ways

Aiming at the problems existing in the existing HSPA system's existing fixed allocation mechanism for channel multiplexing, the embodiment of the present invention dynamically adjusts the allocation mode of accompanying channels according to the current number of HSPA users, so as to meet the needs of access users while ensuring as much as possible The physical properties of the accompanying channel for the access user.

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 3 a, it is a schematic flow chart of the HSPA system accompanying channel allocation method of the embodiment of the present invention, the method includes the following steps:

Step 301, determine the current number of HSPA users;

Step 302, according to the determined number of HSPA users, judge whether to adopt the multiplexing mechanism of the accompanying channel, that is, whether to multiplex the HSPA users on the accompanying channel; To multiplex the HSPA user, perform step 304; otherwise, do not need to multiplex the HSPA user on the accompanying channel, perform step 303;

Step 303, assigning accompanying channel resources for current HSPA users, each HSPA user assigning an accompanying channel, without using the channel multiplexing mechanism;

Step 304, using the companion channel multiplexing mechanism to allocate companion channel resources for the current HSPA user.

In the above step 304, when it is judged that the accompanying channel multiplexing mechanism needs to be used, the existing accompanying channel multiplexing mechanism can be used, such as 2 times frequency division multiplexing or 4 times frequency division multiplexing; During the multiplexing mechanism, further determine the multiplexing multiple used and the accompanying channel to which the multiplexing multiple is applied. In this case, as shown in FIG. 3b, step 304 of the above process may include the following steps:

Step 3041, according to the number of HSPA users, determine the adopted multiplexing multiple and the accompanying channel using the multiplexing multiple;

Step 3042: According to the determined multiplexing factor, time slot division is performed on the corresponding accompanying channel, and the divided time slots are allocated to the corresponding number of HSPA users.

In the above-mentioned step 3041, when determining the multiplexing multiple used and the accompanying channel using the multiplexing multiple, it can be determined that all accompanying channels use the same multiplexing multiple, such as 2 times multiplexing or 4 times multiplexing, the specific multiplexing The multiple can be determined according to the current number of HSPA users to access as many users as possible. For example, for an HSDPA system with 6 downlink accompanying channels in the downlink TS6, when the number of HSDPA users does not exceed 12 (that is, 2 times frequency division multiplexing When the maximum number of access users), use 2 times frequency division multiplexing, when the number of HSDPA users exceeds 12, use 4 times frequency division multiplexing. It is also possible to use low multiplexing (such as 2 times multiplexing) for some accompanying channels, high multiplexing (such as 4 times multiplexing) for some accompanying channels, and use 2 times multiplexing and 4 times multiplexing for some accompanying channels without multiplexing. The number of accompanying channels with and without the multiplexing mechanism can be determined according to the current HSPA user quantity. Preferably, the embodiment of the present invention uses this method to allocate accompanying channel resources. The principle followed by this allocation method is:

Under the premise of accessing as many current HSPA users as possible, low multiplexing (such as 2 times multiplexing) is preferred. When all accompanying channels cannot fully access the current HSPA users with low multiplexing, part of the accompanying channels are used Higher multiplexing (such as 4 times multiplexing), when the current HSPA users still cannot be fully accessed, all accompanying channels use this high multiplexing multiplexing (4 times multiplexing).

The above method is applicable to the resource allocation process of the uplink accompanying channel or the downlink accompanying channel of the HSUPA and HSDPA systems. According to the above principles, for the allocation of downlink accompanying channels in the HSPA system, assuming that the number of current HSPA users is N, the number of downlink accompanying channels is M, and the multiplexing multiples that can be used include 2 times multiplexing and 4 times multiplexing, then the downlink accompanying channels Channel assignments include:

When N≤M, no multiplexing mechanism is used;

When M<N<2M, round N/2 to an integer, and the resulting value is the number of downlink accompanying channels that use 2 times frame division multiplexing, and the remaining downlink accompanying channels do not use the multiplexing mechanism;

When N=2M, all downlink accompanying channels adopt 2 times frame division multiplexing;

When 2M<N<4M, round N/4 to an integer, and the resulting value is the number of downlink accompanying channels using 4 times frame division multiplexing; (N-(N/4 rounded result value)×4) /2 is rounded to an integer, and the resulting value is the number of downlink accompanying channels that use 2 times frame division multiplexing, and the remaining downlink accompanying channels do not use the multiplexing mechanism;

When N=4M, all downlink accompanying channels adopt 4 times frame division multiplexing.

It can be seen that when using the embodiment of the present invention to allocate accompanying channel resources, when the number of users is small and the current user can be accessed without using the multiplexing mechanism, the accompanying channel multiplexing mechanism is not used, thereby ensuring While accepting the current users, maintain good channel performance; as the number of users gradually increases, a higher-capacity multiplexing mechanism will be gradually activated. Although the channel multiplexing mechanism will cause the performance of the accompanying channel to decline, it can be accepted More users; as the number of users decreases, the multiplexing function with lower capabilities will be gradually activated, so that the performance of the accompanying channel will be gradually improved while accepting users as much as possible.

Taking the allocation of downlink accompanying channel resources for users in the HSDPA system as an example below, the allocation process of the accompanying channel in the HSPA system in the embodiment of the present invention is described in detail, and the accompanying channel allocation method in the embodiment of the present invention is different from the existing fixed 4 times frame division. Multiplexing methods are compared.

As shown in Figure 1, the TS6 of the HSDPA system includes 6 downlink accompanying channels. If 4 times frame division multiplexing is used, a maximum of 24 users can be connected, and the currently connected HSDPA users are assumed to be N.

When N≤6, the frame division multiplexing mechanism does not need to be used. As shown in Table 2, each user is assigned a downlink accompanying channel. In view of this situation, when using the existing fixed 4 times frame division multiplexing mechanism, it is necessary to multiplex multiple users in the downlink accompanying channel, and at the same time, there are more downlink accompanying channel resources idle, which will lead to poor channel quality of users. decline; in contrast, in this embodiment, each user is assigned a downlink accompanying channel, and the performance of the accompanying channel will be better than that of a fixed 4 times frame division multiplexing method, and the utilization rate of channel resources is also higher.

Table 2

When 6<N≤12, some downlink accompanying channels adopt 2 times frame division multiplexing, and some downlink accompanying channels do not use frame division multiplexing (when N<12); or all downlink accompanying channels adopt 2 times frame division multiplexing Multiplexing mode (when N=12), as shown in Table 3. In view of this situation, when using the existing fixed 4 times frame division multiplexing mechanism, it is necessary to multiplex 4 users in the downlink accompanying channel, and at the same time, there are more downlink accompanying channel resources idle, which will lead to poor channel quality of users. decrease; in contrast, in this embodiment, only 2 users are multiplexed on the downlink accompanying channel. In the case of N<12, there are still some downlink accompanying channels that do not use frame division multiplexing. Obviously, the The performance will be better than using a fixed 4 times frame division multiplexing method, and the utilization rate of channel resources is also higher.

table 3

When 12<N≤24, some downlink accompanying channels adopt 4 times frame division multiplexing (when N<24), or all downlink accompanying channels adopt 4 times frame division multiplexing (N=24), as shown in Table 4. When some downlink accompanying channels adopt 4 times frame division multiplexing, according to the number of users, some downlink accompanying channels will use 2 frame division multiplexing, and some downlink accompanying channels may even not use frame division multiplexing. For this situation, when using the existing fixed 4 times frame division multiplexing mechanism, it is necessary to multiplex 4 users in the downlink accompanying channel; Double frame division multiplexing, obviously the user's channel quality is better, and even some downlink accompanying channels may not use frame division multiplexing, compared with 4 times frame division multiplexing, obviously the user's channel quality is better, and channel resource utilization rate is also higher. In the case of N=24, there is no obvious difference in user channel quality between the fixed 4 times frame division multiplexing method of the prior art and the downlink accompanying channel allocation method of the embodiment of the present invention.

Table 4

In the embodiment of the present invention, when HSPA users are multiplexed on the companion channel, in order to ensure system performance as much as possible, it can be determined according to factors such as user channel quality to start the multiplexing function for which users or to start updating for users who have started the multiplexing function. High multiplexing function; or according to factors such as user channel quality, determine which users should try not to start the multiplexing function or start a lower multiplexing function for users who have already started the multiplexing function.

Table 5 presents a strategy for enabling the multiplexing function of accompanying channels. Scenario 1 indicates that a higher multiplexing function (i.e., a higher multiplexing factor) needs to be activated due to the increase in the number of users. Scenario 2 indicates that the A reduction in the number of users requires a lower multiplexing function (i.e., a lower multiplexing factor) to be enabled.

table 5

In Table 5, the user SPI represents the scheduling priority indication, and GBR represents the minimum guaranteed rate.

It is also possible to quantify the level indicating that the user activates the multiplexing function in a weighted manner according to various factors, so as to implement a strategy for activating the accompanying channel multiplexing function. For example, for the various factors listed in Table 5, the weight calculation formula is as follows:

W=W1*SPI+W2*channel quality+W3*capacity requirement+W4*GBR+W5*power headroom+……;

Among them, W is the calculated grade, and Wi represents the weighting coefficient of each factor.

Since each adjustment requires a physical channel reconfiguration process, it can be considered differently in combination with the performance of physical channel reconfiguration. For example, when the channel performance is good, the above strategy can be used to dynamically allocate channel resources. Adjustment.

In the HSPA system, resource allocation of accompanying channels is performed by the base station. When the scheduling period arrives, the base station can allocate accompanying channel resources for HSPA users in the above manner according to the current number of HSPA users. Wherein, the base station can obtain the current number of HSPA users through real-time detection, and can also determine the current number of HSPA users according to the traffic statistics model. The traffic statistics model is the historical record of traffic statistics, through which the number of users in each time period can be obtained. Considering business growth and other factors, there may be deviations from the actual situation when determining the current number of users based on the traffic statistics model. Perform a weighted operation on the number of users determined according to the traffic statistics model, so as to finally determine the current number of HSPA users).

In another embodiment of the present invention, the number of users in each period can be determined according to the traffic statistical model (the determined number of users can also be adjusted appropriately), and the number of users in each period can be determined by the above method The method of allocating accompanying channel resources for HSPA users (including whether to use the multiplexing mechanism, the multiplexing factor when using the multiplexing mechanism, and the corresponding accompanying channels, etc.), so as to determine the corresponding accompanying channel resource allocation method for each time period. When the scheduling period arrives, the base station allocates accompanying channel resources in a corresponding accompanying channel resource allocation manner according to the current period. Further, when the base station allocates accompanying channel resources, if the allocation method adopted is the accompanying channel multiplexing method, it can refer to the above-mentioned strategy for starting the accompanying channel multiplexing function to perform accompanying channel resource allocation and dynamic adjustment.

Based on the same technical concept, the embodiment of the present invention also provides a base station. As shown in Figure 4, the base station includes:

The number of users determining unit 401 is used to determine the number of HSPA users in the current scheduling period, and the specific determination method can adopt the method of real-time detection as described above or determine according to the traffic statistics model;

An allocation method determination unit 402, configured to determine the accompanying channel resource allocation method adopted according to the determined number of HSPA users, the accompanying channel resource allocation method includes adopting or not using a multiplexing method;

The channel resource allocation unit 403 is configured to allocate accompanying channel resources for HSPA users according to the determined accompanying channel resource allocation manner.

The allocation mode determination unit 402 determines to adopt the multiplexing mode when judging that the number of HSPA users is greater than the number of accompanying channels. After the multiplexing method is determined, the multiplexing factor and the accompanying channel using the multiplexing factor can also be determined according to the number of HSPA users, so that the channel resource allocation unit 403 can use the determined multiplexing multiple Accompanying channel resource allocation is performed on the accompanying channels of multiplexing multiples. How the allocation method determining unit 402 determines the multiplexing multiple and the implementation of the accompanying channel using the multiplexing multiple according to the number of HSPA users can be performed according to the process described above, and will not be repeated here.

When the channel resource allocation unit 403 allocates accompanying channel resources, it can also use the aforementioned strategy of starting the accompanying channel multiplexing function to perform resource multiplexing according to factors such as the user's SPI and channel quality.

The allocation mode determination unit 402 may be a part of the baseband processing unit of the base station, and the channel resource allocation unit 403 may include a part of the baseband processing unit to implement user scheduling and channel resource allocation, and may also include a part of the radio frequency processing unit to realize the corresponding The HSPA user sends resource allocation indication information.

Based on the same technical idea, the embodiment of the present invention also provides an HSPA system accompanying channel resource allocation system, as shown in Figure 5, the system includes:

The channel allocation method determining means 501 is used to determine the outflow of the adopted channel resource allocation method according to the number of HSPA users corresponding to each time period in the traffic statistics model, and determine the traffic The accompanying channel resource allocation method corresponding to each time period in the statistical model (including whether to use the multiplexing mechanism, the multiplexing multiple used when the multiplexing mechanism is used, and the accompanying channel applied to the multiplexing multiple, etc.), and the determined Accompanied by channel resource allocation information configured in the base station;

The base station 502 is configured to, when the scheduling period arrives, allocate accompanying channel resources for HSPA users according to the accompanying channel resource allocation method corresponding to the current period by querying the associated channel resource allocation information configured thereon. Further, when the base station allocates accompanying channel resources, if the allocation method adopted is the accompanying channel multiplexing method, it can refer to the above-mentioned strategy for starting the accompanying channel multiplexing function to perform accompanying channel resource allocation and dynamic adjustment.

Wherein, the channel allocation method determining means 501 may be a component of the network management system, or may be integrated in the base station equipment.

In summary, the embodiment of the present invention realizes the best combination of access user capabilities and channel performance by dynamically adjusting the multiplexing mode of accompanying channels according to the actual number of access users, instead of only focusing on the ability of the maximum number of access users. Therefore, according to the actual number of access users and accompanying channel resources, the balance between demand and performance can be dynamically realized.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and equivalent technologies thereof, the present invention also intends to include these modifications and variations.
