Description

Information sending method, service processing method and system, base station and mobile station

technical field

The invention relates to the technical field of communication, in particular to an information sending method, a service processing method and system, a base station and a mobile station.

Background technique

With the rapid development of communication technology, Worldwide Interoperability for Microwave Access (WiMAX), also known as 802.16 wireless metropolitan area network, can achieve a high coverage of 25 to 30 miles in the field of data communication. (Institute of Electrical and Electronics Engineers, IEEE) 802.16 standard series as its air interface protocol. The IEEE 802.16 standard series so far includes seven standards: 802.16, 802.16a, 802.16c, 802.16d, 802.16e, 802.16f, and 802.16g. Among them, 802.16e (16e for short) belongs to the air standard for mobile broadband wireless access.

The development trend of wireless access technology is to introduce new technologies, such as Orthogonal Frequency Division Multiple (OFDM), Multiple Input Multiple Output (Multiple Input Multiple Output, MIMO) Coverage and achieve a certain degree of mobility, coexist and complement each other with the third generation digital communication (3rd Generation, 3G) network. Therefore, 802.16e technology has become the focus of attention in this field. On the basis of 802.16e, WiMAX proposes a new enhanced technology 802.16m (abbreviated as 16m). 16m needs to be compatible with the current 16e.

In a general OFDMA system, there are generally two modes of channelization design: one is to disperse frequency (subcarrier) resources in resource units to obtain frequency diversity gain, and this mode is called distributed mode; The other is to use the feature of frequency selectivity to allocate continuous frequency resources suitable for users to users. This mode is called localized mode or adjacent mode. There are a variety of specific channel designs in 16e, and the partially used subcarriers (partial usage of sub channels, PUSC) are a distributed channel design. In the basic resource unit of each PUSC, it is composed of a plurality of subcarrier resources dispersed in frequency to obtain frequency diversity gain.

Since 16m must be compatible with 16e, in the uplink subframe of 16m, it can be multiplexed with the zone (zone) of 16e through time division multiplexing mode (TDM) or frequency division multiplexing mode (FDM), that is, through time division or frequency division, Allocate certain resources to 16e to ensure the backward compatibility of 16m. In addition, the channel design of the uplink (UL) of 16m also adopts distributed mode and localized mode, but the resources of each subframe in 16m are divided into multiple basic resource allocation units, and the size of each unit is 18 subcarriers×6 OFDM symbols, for distributed resources, 18 subcarriers are scattered, and for localized mode, 18 subcarriers are continuous. Since the size of each sub channel in the 16e PUSC structure is 24 subcarriers × 3 OFDM symbols, and the size of each unit in 16m is 18 subcarriers × 6 OFDM symbols, so if you want to ensure that 16m and 16e are in a UL subframe In FDM multiplexing, the two are in conflict,

At present, a new 16m channel design is proposed following the design idea of 16e PUSC, that is, when 16m and 16e FDM are multiplexed, the distributed design of 16m also uses 6 discrete tiles, and each tile consists of 4 subcarriers × 6 OFDM symbols , so that 16m and 16e can effectively perform FDM multiplexing.

However, the inventor found in the process of implementing the above technical solution that: the base station (BS) did not indicate various types and ratios of uplink subframes of the 16m mobile station (MS). Therefore, the 16m MS cannot correctly select a different channel structure according to the type of the UL subframe for corresponding processing.

Detailed ways

The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

As shown in Figure 1, it is a flowchart of an embodiment of the information sending method of the present invention, and the method includes:

Step 101, assembling control parameter information;

The base station (BS) assembles control parameter information, the above control parameter information includes the proportional relationship between the downlink subframe and the uplink subframe and the downlink subframe corresponding to the proportional relationship between the downlink subframe and the uplink subframe Allocation information of road subframes and uplink subframes;

Step 102, sending control parameter information to the mobile station.

The base station sends control parameter information to the mobile station (MS) through the forward link broadcast channel (BCH). The length of the above control parameter information can be 8 bits, so when the BS broadcasts 8 bit information through the above forward link broadcast channel, The design of the BCH will not be affected; in addition, the length of the above-mentioned control parameter information can also be set as required; the ratio between the above-mentioned downlink DL subframe and uplink UL subframe can be 5:3, or 4: 4 etc;

For a certain length of control parameter information, the number of DL subframes (subframes) in the proportional relationship between DL subframes and UL subframes indicates the length of the DL subframe type (type) indication (bitmap), and the DL subframe and UL subframe The number of UL subframes in the proportional relationship of the frame indicates the length of the ULsubframe type bitmap; for example, when the length of the above-mentioned control parameter information is 8 bits, and the above-mentioned proportional relationship between the DL subframe and the UL subframe is 5:3, it means There are 5 DL subframes and 3 UL subframes. At this time, the high 5bits of the subframe type bitmap, that is, bit7~bit3, correspond to the DL subframe type indication, and the low 3bits, that is, bit2~bit0, correspond to the UL subframetype indication. ;Similarly, if the ratio between DL subframe and UL subframe is 4:4, it means that there are 4 DL subframes and 4 UL subframes, that is, bit7~bit4 corresponds to the DL subframe type indication, and bit3~ Bit0 corresponds to the UL subframe type indication.

For a DL subframe type bitmap with 4 DL subframes, each bit corresponds to 1 DL subframe, if the corresponding bit is set to '1', it means that the DL subframe is reserved for 16e, if the corresponding bit is set to ' 0', it means that the DL subframe is reserved for 16m, as shown in Figure 2a, which is the corresponding schematic diagram of Embodiment 1 of the downlink subframe allocation information of the present invention, in which bitmap='1100' is used as an example to illustrate For the allocation information of the downlink subframe, FIG. 2b and FIG. 2c respectively illustrate the allocation information of the downlink subframe by taking bitmap='0000' and bitmap='1001' as examples.

For a UL subframe type bitmap with 3 UL subframes, the UL subframe type bitmap has 3 bits, and the UL subframe type bitmap can be set according to the following rules, see Table 1 for details.

Table 1

000 Subframe 0&1&2, pure 16m 100 Subframe 0 support FDM legacy user; Subframe1&2 pure 16m 110 Subframe 0&1 support FDM legacy user; Subframe 2 pure 16m 111 Subframe 0&1&2, FDM legacy support 001 Subframe 0&1, pure 16eSubframe 2, pure 16m 011 Subframe 0, pure 16eSubframe 1&2, pure 16m 010 Reserved 101 Reserved

Among them, when the bitmap is set to 000, it means that all three UL subframes are reserved for 16m; when the bitmap is set to 100, it means that the first UL subframe is 16e and 16m are multiplexed by FDM, and the last two UL subframes are Reserved for 16m; when the bitmap is set to 110, it means that the first and second UL subframes are 16e and 16m using FDM multiplexing, and the last UL subframe is reserved for 16m; when the bitmap is set to 111, Indicates that all 3 UL subframes are 16e and 16m are multiplexed by FDM; when the bitmap is set to 001, it means that the first 2 UL subframes are reserved for 16e, and the last UL subframe is reserved for 16m. When the bitmap is set When it is 010 or 101, it means to be determined, and it can be set according to the need when needed. In addition, as shown in FIG. 3a, it is a schematic diagram corresponding to Embodiment 1 of the uplink subframe allocation information of the present invention. The schematic diagram takes bitmap equal to '110' as an example to illustrate the corresponding relationship of allocation information. FIG. 3b and FIG. 3c respectively use Bitmap is equal to '000' and '111' as an example to illustrate the corresponding relationship of allocation information;

In order for the MS to perform corresponding service processing, the BS needs to send control parameter information to the MS, so that the MS can select resources and channel structures to send and receive information according to the subframe type of the subframe specified by the above control parameter information.

In the above information sending method, the BS sends the control parameter information including the uplink and downlink subframe ratio information and the corresponding uplink and downlink subframe allocation information to the MS, so that the MS can obtain the UL subframe and DL subframe according to the above control parameter information. The subframe type of the subframe, and select appropriate resources and channel structures according to the obtained subframe types of the UL subframe and DL subframe to perform corresponding service processing.

As shown in Figure 4, it is a flow chart of an embodiment of the business processing method of the present invention, and the method includes:

Step 201, receiving control parameter information from the base station, the above control parameter information includes the proportional relationship and allocation information between the downlink DL subframe and the uplink UL subframe;

Step 202, according to the proportional relationship between the downlink subframe and the uplink subframe contained in the above information and the downlink subframe and the uplink subframe corresponding to the above proportional relationship between the downlink subframe and the uplink subframe Frame allocation information, obtaining subframe types of downlink subframes and uplink subframes;

The MS can obtain the subframe type of each UL and DL subframe according to the above-mentioned proportional relationship between the downlink subframe and the uplink subframe and the allocation information;

Step 203: Select resources and channel structures according to the subframe types of the above-mentioned uplink subframe and uplink subframe to perform corresponding service processing.

If the type of subframe acquired by the MS is pure 16m UL subframe, the MS performs service processing according to the resource and channel structure of 16m. For example, the size of the resource unit is 18×6, and the replacement method is processed according to the newly designed replacement method of 16m; And once the MS is allocated to the UL subframe multiplexed by 16m and 16e through FDM, the MS knows that it should be processed according to the resource and channel structure of 16m compatible with 16e. The resource unit is 24×6 in size, and each resource unit is It consists of 6 small resource blocks, and the replacement method is processed according to the 16e PUSC mode.

In a backward compatible 16m system, the scheduling sequence is shown in Figure 5. From Figure 5, it can be seen that the UL resource scheduling of 16m is after the resource scheduling of 16e, so in the subframe where 16e and 16m are multiplexed by FDM, BS can allocate resources not used by 16e to 16m MS. Since the channel design of 16m MS also adopts the same design as 16e PUSC, their resources will not conflict. Since the resource scheduling is performed by the same base station using a unified numbering method for all logical resource units, the BS will allocate the unused resources of 16e to 16m for use. For example, in a 16e and 16m FDM UL subframe, taking 10MHz bandwidth as an example, according to the 16e PUSC channel design, there are 35 subchannels. If 16e uses the first 10 subchannels, then the BS can schedule the following The 25 sub channels are allocated to 16m users. Because they use the same channel permutation method, their physical resources will not conflict.

The above service processing method enables the MS to receive the parameter control broadcast by the BS including the proportional relationship between the downlink subframe and the uplink subframe and the allocation information of the corresponding downlink subframe and uplink subframe Information, so that the subframe types of the UL subframe and the DL subframe can be obtained according to the above parameter control information, and resources and channel structures can be selected according to the subframe types of the above UL subframe and DL subframe to perform corresponding service processing.
