Description

Transmission resource configuration method, access device and terminal

Technical field

The embodiments of the present invention relate to a data transmission technology, and in particular, to a transmission resource configuration method, an access device, and a terminal.

Background technique

At present, the International Telecommunication Union (ITU) proposes three major communication scenarios: enhanced mobile broadband communication scenarios, massive machine-like communication scenarios, and highly reliable low-latency communication scenarios. In the massive machine type communication scenario, various terminals having battery modules exchange information with the network. In the communication process, in order to save power, the terminal is in a dormant state for most of the time, and enters an active state to transmit uplink information only when the service needs to be transmitted.

Generally, the terminal can transmit uplink information in the following two manners: mode 1: using the scheduling-based resource to transmit uplink information; and second, using the contention-based resource to transmit uplink information. In the first mode, when the terminal needs to send the uplink information, the terminal enters the active state from the dormant state, requests the access device to allocate the scheduling resource, and then transmits the uplink information on the allocated scheduling resource. In this process, multiple information interactions are required to allocate scheduling resources, resulting in a large power consumption of the terminal and a delay in transmission. Compared with the first method and the second method, in consideration of multiple services, there are multiple sizes of data packets, and at the same time, in order to counter the fading of the wireless channel between the terminal and the access device, a data packet may have multiple modulation and coding modes. The access device allocates one or more orthogonal contention resource blocks of the same or different size to the terminal, and notifies the terminal, so that data packets of different sizes or different modulation and coding modes are transmitted on the most suitable contention resource block. In this process, the terminal does not need to send a scheduling request to the access device to allocate the scheduling resource, which reduces the conversion delay between the sleep state and the active state and the power consumption of the terminal to some extent.

However, in the foregoing mode 2, when the penetration rate of the terminal is low, for example, when there are relatively few terminals accessing the same access device, or when the service of the terminal is relatively small, the access device still allocates a large number of competing resource blocks, resulting in The utilization of competitive resource blocks is low, resulting in waste of resources.

Summary of the invention

The embodiment of the invention provides a transmission resource configuration method, an access device and a terminal, which are transmitted through The CBB that transmits the uplink information divides one or more sub-CBBs, so that the terminal selects the target sub-CBB from the plurality of sub-CBBs to transmit the uplink information, thereby saving competing resources when the penetration rate of the terminal is low.

detailed description

Currently, in the process of transmitting uplink information by using contention-based resources, the access device determines the number of contention-based resources according to system load, expected data packet size, channel characteristics, number of machine users, past conflict conditions, and the like. And the size of each contention-based resource, and assign a modulation coding scheme to each contention-based resource. Specifically, refer to FIG. 1. FIG. 1 is a schematic diagram of configuration of a current contention-based resource. Referring to FIG. 1, the access device is configured with three Contention Based Blocks (CBBs), wherein the size of the CBB1 is 20 bytes, and the modulation and coding mode is quadrature phase shift keying (Quadrature Phase Shift). Keying, QPSK), the code rate is 1/3 code rate; the size of CBB2 is 60byte, the modulation coding mode is QPSK, the code rate is 1/2 code rate; the size of CBB3 is 80byte, and the modulation coding mode is QPSK, the code rate is 1/3 bit rate.

After the contention-based resource is configured, the access device uses the control signaling to semi-statically or dynamically notify the terminal of the content of the contention-based resource, including: size and location of each contention-based resource, modulation and coding mode, and minimum power. Clearance value. If the power headroom value of the terminal is less than the minimum power headroom value of a certain contention-based resource, the terminal does not select the contention-based resource to transmit the uplink information.

The access device calculates the possibility factor according to factors such as system load, available resources, number of supported terminals, and data size of the terminal, and sends the possibility to the terminal, so that the terminal feels that it is Whether to use the contention-based resources to transmit uplink information. Generally, under light load conditions, a terminal has a relatively high probability of transmitting uplink information by using a contention-based resource, and under high load conditions, the terminal has a lower possibility of transmitting uplink information by using a contention-based resource, thereby Reduce the possibility of conflict.

In the foregoing method for configuring a transmission resource, considering that multiple services have multiple sizes of data packets, and at the same time, to counter the fading of the wireless channel between the terminal and the access device, one data packet may have multiple modulation and coding modes, and access The device allocates one or more orthogonal contention resource blocks of the same or different size to the terminal, and notifies the terminal, so that data packets of different sizes or different modulation and coding modes are transmitted on the most suitable contention resource block. In this process, different data packets and different modulation and coding modes require mutually orthogonal competitive resource blocks. When the penetration rate of the terminal is low, the access device still allocates a large number of competitive resource blocks, resulting in the utilization of the competitive resource blocks. Low, resulting in wasted resources.

In view of this, the present invention provides a transmission resource configuration method, by dividing a CBB transmitting uplink information into one or more sub-CBBs, so that the terminal selects a target sub-CBB from a plurality of sub-CBBs to transmit uplink information, thereby being at the terminal. When the penetration rate is low, the competition resources are saved.

For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), etc. .

The access device involved in the present application may be a base station, an access point (AP), or the like. The base station may refer to a device in the access network that communicates with the wireless terminal through one or more sectors on the air interface. The base station can be used to convert the received air frame to the IP packet as a router between the wireless terminal and the rest of the access network, wherein the remainder of the access network can include an Internet Protocol (IP) network. The base station can also coordinate attribute management of the air interface. For example, the base station may be a Base Transceiver Station (BTS) in GSM or CDMA, or may be a base station (NodeB) in WCDMA, or may be an evolved base station in LTE (NodeB or eNB or e-NodeB, evolutional Node B), this application is not limited.

In the following, for the convenience and clarity of the description, the technical scheme of the present invention will be described in detail by taking the system architecture as the OFDM system and the access device as the base station as an example. Specifically, please refer to Figure 2.

2 is a schematic structural diagram of a wireless communication system to which a transmission resource configuration method according to the present invention is applied. The wireless communication system may be a CDMA based UMTS system or an OFDM based LTE system. As shown in FIG. 2, in the example of the present invention, the access device configures a first CBB set for the terminal, and divides the first CBB in the first CBB set into one or more sub-CBBs and notifies the terminal, so that the terminal is from the first CBB. A suitable target sub-CBB is selected in the set to transmit uplink information. Next, the notification method of the present invention will be described in detail based on FIG.

FIG. 3 is a signaling diagram of Embodiment 1 of a method for configuring a transmission resource according to the present invention. In this embodiment, an access device interacts with a terminal, and is applicable to a scenario in which the access device configures a transmission resource for the terminal. Specifically, the embodiment includes the following steps:

101. The access device configures, by the terminal, a first contention resource block CBB set.

Wherein the first CBB set includes at least one CBB, and each CBB is divided into one One or more sub-CBBs, when the first CBB set includes at least two CBBs, each CBB is orthogonal to each other. Generally, the transmission of uplink data is transmitted through dedicated uplink transmission resources. However, when there is no dedicated uplink transmission resource, it is necessary to contend for resources to transmit uplink information, and the resources obtained through competition are resources based on Contention Based (CB). The CB resources are divided in the time domain and the frequency domain to obtain different resource blocks, that is, a Contention Based Block (CBB).

In the embodiment of the present invention, the CBBs are mutually orthogonal, that is, the CBBs do not overlap each other. For example, for an OFDM-based LTE system, each CBB is orthogonal to each other, meaning that the CBBs do not overlap in the time domain and the frequency domain; For example, for a CDMA-based UMTS system, each CBB is orthogonal to each other, meaning that each CBB does not overlap in the time domain and the codeword domain; for example, in other communication systems, each CBB may not be in the airspace. Overlap, or each CBB does not overlap in a single domain or multiple combined domains in the time domain, frequency domain, codeword domain, airspace, and the like.

In this step, the access device divides each CBB in the first CBB set into one or more sub-CBBs, and each sub-CBB may be orthogonal or non-orthogonal to each other. For example, the first CBB set includes three CBBs, and each (or part of) CBBs can be divided into two mutually orthogonal sub-CBBs or non-orthogonal sub-CBBs. In the division process, the division may be performed by frequency domain orthogonal or non-orthogonal, time domain orthogonal or non-orthogonal. Taking the frequency domain division as an example, suppose a CBB occupies 10 subcarriers in the frequency domain, and the number of the subcarriers is 1 to 10, respectively, and the division process can all the frequency domain resources of the CBB, that is, all subcarriers. Dividing to obtain two sub-CBBs, for example, when the two sub-CBBs occupy subcarriers 1 to 5, 6 to 10, or 1 to 3, 4 to 10, etc. in the time domain, respectively, the two sub-CBBs are orthogonal Sub-CBB; for example, when the two sub-CBBs occupy subcarriers 1 to 6, 5 to 10, or 1 to 7, 4 to 10, etc. in the frequency domain, the two sub-CBBs are non-orthogonal sub-CBBs; In addition, part of the frequency domain resources of the CBB, that is, part of the subcarriers may be divided to obtain two sub-CBBs, for example, when the two sub-CBBs occupy subcarriers 1 to 4, 5 to 8, or 1 in the time domain, respectively. When ～5, 7~10, etc., the two sub-CBBs are sub-CBBs that are orthogonal to each other.

102. The access device sends the first indication information to the terminal.

The first indication information includes information about each CBB in the first CBB set and information about each of the sub-CBBs, and is used by the terminal from the first CBB set according to the first indication information. Select the target CBB or sub-CBB to transmit the upstream information.

Specifically, after the first CBB set is configured for the terminal, the access device sends the first indication information to the terminal during the access, exit, or each adjustment period, so that each of the first CBB sets The information of the CBB and the information of each sub-CBB are notified to the terminal, and the information of each CBB includes the size, location, load, and the like of the CBB; the information of each sub-CBB includes the size, location, load, and the like of the sub-CBB. During the notification process, the first indication information may be transmitted by using broadcast, dedicated signaling, or multicast signaling.

For the sake of clarity, in the embodiment of the present invention, each CBB in the first CBB set is used as the first layer CBB, the first layer is denoted as L1 (Layer1), and the first CBB in the first CBB set is divided into The sub-CBB is the second layer CBB, and the second layer is denoted as L2 (Layer 2).

103. The terminal selects a target sub-CBB from the first set of CBBs according to the first indication information.

The first indication information carries information such as the size and load of each CBB or each sub-CBB. Therefore, after receiving the first indication information, the terminal may select, according to the size of the uplink information to be uploaded, the sub-information capable of transmitting the uplink information. CBB, when there are a plurality of sub-CBBs, the sub-CBB with a light load is further selected from the plurality of sub-CBBs as the target sub-CBB.

104. The terminal transmits uplink information by using the target sub-CBB.

In the above steps 103 and 104, after receiving the first indication information, the terminal selects an appropriate target sub-CBB from the first CBB set according to its own capabilities, service requirements, and the like to transmit uplink information.

It should be noted that, in the foregoing steps 103 and 104, after receiving the first indication information, the terminal may select one CBB transmission uplink information from the first CBB set.

The transmission resource configuration method provided by the example of the present invention, the access device configures a first CBB set for the terminal, the CBB in the first CBB set is divided into one or more sub-CBBs, and then the access device will include the first CBB set. The information of each CBB and the first indication information of the information of each sub-CBB are sent to the terminal, so that the terminal selects the target sub-CBB from the first CBB set according to the first indication information and transmits the uplink information, compared to the first CBB. A modulation coding mode and a fixed-size uplink information can be transmitted. By dividing the first CBB in the first CBB set into one or more sub-CBBs, each CBB or sub-CBB can be used to transmit different modulation coding modes and different Up-and-down information of size, thereby saving competitive resources when the penetration rate of the terminal is low.

Generally, the uplink information includes control information and data information. In the example of the present invention, the control information and the data information can be transmitted on the same sub-CBB. In this case, it can be understood as control information and The data information is transmitted on the same contention resource, and the data information may be transmitted on the sub-CBB divided by a certain CBB in the first CBB set, and the control information is transmitted on the CBB in the second CBB set. It can be understood that control information and data information are transmitted on different competing resources. Hereinafter, the present invention will be described in detail from the case where the control information and the data information are transmitted on the same contention resource, and the control information and the data information are transmitted on different competing resources, respectively.

The first case, control information, and data information are transmitted on the same competitive resource. At this time, in the first embodiment, the uplink information includes control information and data information. In this case, when the control information and the data information are transmitted in the same CBB or sub-CBB, the control information and the data information may be combined or coded separately and combined to reduce the terminal implementation complexity.

First, the initial conditions.

It is assumed that the control information and the data information sent by the terminal may have the same or different modulation and coding modes, and the control information and the data information of the terminal may be configured to be combined or separately encoded by the indication, and on an uplink competitive resource. , that is, the same sub-CBB transmission. It is assumed that the control information and the data information sent by the terminal are combined or coded and combined, and the required size of the uplink transmission resource block is N, which is defined as: {CBB ₁ , CBB ₂ , , , CBB _n ,,, CBB _N },among them

For example, CBB ₁ can represent 20byte data packets, 1/2 code rate, QPSK modulation; CBB ₂ can represent 20byte data packets, 1/3 code rate, QPSK modulation; CBB ₃ can represent 40byte data packets, 1/2 code rate, QPSK modulation and so on.

Second, the CBB configuration process.

When the terminal initially accesses the network, the access device allocates the first CBB set to the terminal; when the service demand of the terminal that has accessed the network changes, or the load of the competing resource block changes, the access device adjusts the terminal. The first CBB collection. Upon initial allocation or adjustment, the base station configures a first CBB set containing one or more orthogonal CBBs for the terminal, the sizes of the CBBs being the same or different. For details, refer to FIG. 4. FIG. 4 is a schematic diagram of a first CBB set in a method for configuring a transmission resource according to the present invention. Further, one or more CBBs in the first CBB set are internally divided into one or more orthogonal or non-orthogonal sub-CBBs, and the sizes of the sub-CBBs are the same or different. For details, refer to FIG. 5A. 5A, FIG. 5A is a schematic diagram of dividing a CBB from a time domain into two orthogonal sub-CBBs according to a method for configuring a transmission resource according to the present invention, and FIG. 5B is a method for configuring a transmission resource according to the present invention to divide a CBB from a frequency domain into two. Schematic diagram of orthogonal sub-CBB, FIG. 5C is a transmission of the present invention In the resource configuration method, a CBB is divided into 8 orthogonal sub-CBBs from the time domain and the frequency domain, and FIG. 5D is a method for configuring a transmission resource according to the present invention, and dividing a CBB from the time domain and the frequency domain into four orthogonal sub-categories. FIG. 5E is a schematic diagram of dividing a CBB from a frequency domain into two non-orthogonal sub-CBBs according to a method for configuring a transmission resource according to the present invention, and FIG. 5F is a CBB from a frequency domain and a time in a transmission resource configuration method according to the present invention; FIG. 5G is a schematic diagram of dividing a sub-CBB from a CBB resource in a method for configuring a transmission resource according to the present invention; FIG. 5H is a schematic diagram of a CBB in a transmission resource configuration method according to the present invention; Schematic diagram of the division of some resources.

Referring to FIG. 4, the first CBB set includes L1-CBB1, L1-CBB2, and L1-CBB3, which are orthogonal to each other. The division of L1-CBB1 is performed, and the divided sub-CBB includes but is not limited to the case shown in FIGS. 5A to 5F. For example, in FIG. 5A, L1-CBB2 are divided into orthogonal L2-sub-CBB1 and L2-sub-CBB2; as in FIG. 5C, L1-CBB2 is divided into orthogonal L2-sub-CBB1~L2-sub-CBB8 As another example, in FIG. 5F, L1-CBB2 are divided into non-orthogonal L2-sub-CBB1~L2-sub-CBB6.

In the above-described FIGS. 5A to 5F, the resources of the entire L1-CBB2 are divided to obtain the sub-CBB. However, the present invention is not limited thereto. In other feasible implementations, some resources of L1-CBB2 may be divided to divide orthogonal or non-orthogonal sub-CBBs, and FIG. 5G is non-positive. cross.

In the above-mentioned FIG. 5A to FIG. 5G, one L1-CBB2 is divided into a plurality of sub-CBBs. However, the present invention is not limited thereto. In other feasible implementation manners, only one sub-CBB may be divided for L1-CBB2. As shown in FIG. 5H, there are resources of L1-CBB2 at this time.

In the above-described FIG. 4 and FIG. 5A to FIG. 5F, each CBB is orthogonal to each other, and the CBBs are competitive resource blocks in which at least one of a time domain, a frequency domain, a codeword domain, and a spatial domain are orthogonal to each other. Similarly, each sub-CBB is orthogonal, and similarly, the sub-CBBs are competing resource blocks orthogonal to at least one of a time domain, a frequency domain, a codeword domain, and an airspace. Obviously, since the sub-CBB of the second layer exists inside the first layer CBB, the sub-CBB of the second layer is not orthogonal to the CBB of the first layer to which it belongs.

It should be noted that, in the above description for the sake of clarity, in the FIGS. 5A to 5H, the sub-CBB of the second layer is drawn on the upper portion of the CBB of the first layer. In reality, however, the sub-CBB of the second layer is located inside the first layer CBB.

Again, the CBB indicates the process that the access device sends the first indication information to the terminal.

The access device collects the capability level information of the terminal, where the capability level information includes the size of the service data packet supported by the terminal, the modulation and coding mode, and the maximum transmit power. According to the information, the access device configures the first CBB set for the terminal. And dividing the CBB in the first CBB set into one or more mutually orthogonal or non-orthogonal sub-CBBs, and then notifying the information of each CBB included in the first CBB set and the information of each sub-CBB to the terminal, so that The terminal selects the target sub-CBB in the first CBB set to transmit control information and data information.

Hereinafter, the configuration of the first indication information will be described by taking an OFDM-based wireless communication system as an example. The first indication information includes information of each CBB in the first CBB set and information of each sub-CBB. Specifically, each first layer CBB, that is, information of each L1-CBB includes: a starting carrier position, a number of carriers, a frame interval, a number of persistent frames, whether control information and data information are jointly encoded, combined, or respective The modulation coding mode, the number of supported L2-sub-CBBs, whether the L2-sub-CBB overlap is allowed, and the load condition of the L1-CBB. Specifically, refer to FIG. 6A, which is a L1-CBB in the transmission resource configuration method of the present invention. Information schematic.

Referring to FIG. 6A, the starting carrier position, the number of carriers, the frame interval, and the number of persistent frames represent the size and position of L1-CBB. The frame interval is used to determine the starting frame number of L1-CBB, and the current frame number can be used. For the frame interval modulo, it can be agreed that the frame number of the modulo result is a fixed positive integer or 0 is the starting frame number; if the control information and the data information are jointly encoded, the control information and the data information combined modulation code in FIG. 6A The mode field is valid, otherwise the control information modulation coding mode and the data information modulation coding mode are respectively indicated; the L2-sub CBB type number is used to represent how many sizes of L2-sub CBBs can exist in each L1-CBB, if the number of categories is 0, there is no L2-sub CBB. At this time, the L1-CBB load status field exists; otherwise, there is no existence; the load status indicates the current L1-CBB load information, and the load information can be the number of users, the bit error rate, and the demodulation. Signal to Interference Ratio (SIR), business reach, etc.

The information of L1-CBB may indicate that there are multiple L2-sub CBBs, and the information of each L2-sub CBB includes: starting carrier position, number of carriers, frame interval, number of persistent frames, control information and data information joint modulation coding The method, the control information modulation and coding mode, the data information modulation and coding mode, the load status, the number of overlapping carriers, and the like. For details, refer to FIG. 6B, which is a schematic diagram of information of the L2-sub CBB in the transmission resource configuration method of the present invention.

Referring to FIG. 6B, the starting carrier position, the number of carriers, the frame interval, and the number of persistent frames represent the size and position of the L2-sub CBB. The starting carrier position is used to determine the frequency domain of the L2-sub CBB. In addition, it is also used to determine which L1-CBB the L2-sub CBB belongs to. Specifically, in which L1-CBB the starting carrier position is, L2-CBB belongs to which L1-CBB; the number of overlapping carriers is only in the figure. Whether or not the L2-sub CBB overlap is allowed to be "yes" in 6A, and can be used to determine the starting position of the next L2-sub CBB of the same size, and it is possible to calculate how many of the L1-CBBs are included in the L1-CBB as described above. The L2-sub CBB of the size and their position; if the control information and the data information of the L1-CBB described by the L2-sub CBB are jointly encoded, the control information and the data information of the L2-sub CBB are jointly modulated by the coding mode field. Otherwise, the L2-sub CBB control information modulation coding mode and the data information modulation coding mode respectively indicate; the load status indicates the current L2-sub CBB load information, and the load information may be the number of users, the bit error rate, the demodulated SIR, Business reach rate, etc.

Finally, the uplink information transmission process.

The terminal selects the target sub-CBB to send uplink information according to the capability of the terminal, the service requirement, and the first indication information sent by the access device, and the access device demodulates at all possible CBB locations configured, and the access device can use interference cancellation, Advanced receivers such as joint detection simultaneously demodulate uplink information transmitted on multiple non-orthogonal sub-CBBs. The uplink information includes control information and data information.

Taking the OFDM-based wireless communication system as an example, the content of the control information includes: the terminal identity identifier and the number of retransmissions. For details, refer to FIG. 6C. FIG. 6C is the same as the data information and the control information in the transmission resource configuration method of the present invention. Schematic diagram of control information when transmitting on a transmission resource.

Referring to FIG. 6C, the control information includes a terminal identity identifier and a number of data packet retransmissions.

The access device determines, according to the information that the control information and the data information are jointly encoded, that the control information and the data information are separately encoded; and further determining whether to perform hybrid automatic according to the identity identifier and the number of retransmissions. Retransmission request HARQ merging; or determining whether to perform automatic retransmission request ARQ merging according to the identity identifier and the number of retransmissions.

In addition, the access device determines, according to the information that the control information and the data information are jointly encoded, that the control information and the data information are jointly encoded; and further determining whether to execute according to the identity identifier and the number of retransmissions. Automatic retransmission request ARQ merge.

In the foregoing transmission resource configuration method, the control information and the data information are transmitted on the same contention resource. When the terminal penetration rate is low, even if the terminal has multiple capability levels, the capability level includes the modulation and coding mode supported by the terminal, and the data packet size. Information such as maximum transmit power, but the access device only needs to allocate less contention-based resources to support multiple requirements of the terminal, saving competition-based resources, and as the penetration rate of the terminal is increased, the access device can be based on Load of each competing resource block Information to adjust the uplink transmission of competitive resources, and improve the utilization and allocation flexibility of contention-based resources.

The second case, control information and data information are transmitted on different competing resources. At this time, in the first embodiment, the uplink information includes data information. In this case, when the CBB for transmitting the control information and the CBB to which the sub-CCB for transmitting the data information belong are different, the control information and the data information can independently adopt respective modulation and coding modes, and the base station side can separately adjust and control the data. The load of the information CBB and the control information CBB can simultaneously support the base station to perform HARQ combined reception of the data information CBB, and improve the receiving performance of the base station.

First, the initial conditions.

It is assumed that the control information and the data information sent by the terminal may have the same or different modulation and coding modes, and the control information and the data information of the terminal are separately transmitted on different competing resources. Assume that the size of the uplink transmission resource block required for the control information sent by the terminal has a total of M classes, and is defined as:

among them

Assume that the size of the uplink resource block required by the data information sent by the terminal has a total of N categories, which are defined as: {CBB ₁ , CBB ₂ , , , CBB _n ,,, CBB _N }, where

Second, the CBB configuration process.

When the terminal initially accesses the network, the access device allocates the first CBB set and the second CBB set to the terminal; when the service demand of the terminal that has accessed the network changes, or the load of the competing resource block changes, the access The device adjusts the first CBB set and the second CBB set of the terminal. The first CBB set is used to transmit data information, the second CBB set is used to transmit control information, the second CBB set includes at least one CBB, and each CCB included in the second CBB set and the first CBB set Each of the included CBBs is orthogonal to each other, and when the second CBB set includes at least two CBBs, each CBB is orthogonal to each other. For details, refer to FIG. 7. FIG. 7 is a schematic diagram of a first CBB set and a second CBB set in a method for configuring a transmission resource according to the present invention. Among them, the upper right of CBB is marked with d for data information transmission, and the upper right c is for control information transmission.

Since the configuration of the first CBB set has been explained in detail since the first case described above, the configuration of the second CBB set is mainly emphasized. Specifically, when initially allocated or adjusted, the base station configures, for the terminal, a second set of CBBs including one or more orthogonal CBBs, and the sizes of the CBBs may be the same or different. Please refer to FIG. 7, the second CBB set includes

The CBB in the first CBB set and the CBB in the second CBB set may be one-to-one mapping, or may not be mapped one by one, that is, one CBB in the second CBB set may correspond to multiple CBBs in the first CBB set, but The CBB in the first CBB set is aligned in time with the CBB in the corresponding second CBB set. For example, in Figure 7,

Can map

Can also map

But can't map

and

Can only map

In the second case, the CBB in the first CBB set may be referred to as the CBB of the data information, and the CBB in the second CBB set may be referred to as the CBB of the control information.

Again, the CBB indicates the process that the access device sends the second indication information to the medium terminal.

The access device adjusts the second CBB set when the terminal accesses or the terminal exits, or periodically adjusts the second CBB set, and notifies the terminal of the information of each CBB in the adjusted second CBB set, that is, The terminal sends a second indication message. In the notification process, the second indication message may be sent by using broadcast, dedicated signaling, or multicast signaling, etc., so that the information of each CBB included in the second CBB set is notified to the terminal, so that the terminal selects a target from the second CBB set. CBB transmits control information.

It should be noted that, in the foregoing embodiment, the first indication message includes information of each CBB in the first CBB set and information of each sub-CBB, and the second indication message includes information of each CBB in the second CBB set. However, in an actual implementation process, the first indication message and the second indication message may be combined into one message simultaneously or not simultaneously sent to the terminal by means of broadcast, dedicated signaling, etc., so that when the control information and the data information are respectively in different competing resources When transmitting on a block, the terminal may select the target sub-CBB to transmit data information, and select the target CBB to transmit control information.

Hereinafter, the configuration of the second indication information will be described by taking an OFDM-based wireless communication system as an example. The second indication information includes information of each CBB in the second CBB set. Specifically, the information of each CBB in the second CBB set includes: a starting carrier position, a number of carriers, a frame interval, a number of persistent frames, and a load status. For details, refer to FIG. 8A, FIG. 8A is a transmission resource of the present invention. Schematic diagram of the information of each CBB in the second CBB set in the configuration method.

Referring to FIG. 8A, for a specific CBB in the second CBB set, the starting carrier position, the number of carriers, the frame interval, and the number of persistent frames represent the size and position of the CBB, and the frame interval is used to determine the CBB. The starting frame number can be modulo the frame interval by the current frame number, and the frame number of the fixed analog integer or 0 can be agreed to be the starting frame number; the load status indicates the load information of the CBB, and the load information can be The number of users, the bit error rate, the demodulated SIR, the service arrival rate, and the like.

Finally, the uplink information transmission process.

The terminal selects the target sub-CBB to send the data information according to the capability of the terminal, the service requirement, and the first indication information sent by the access device; and the terminal selects the target according to the capability of the terminal, the service requirement, and the second indication information sent by the access device. The CBB sends control information.

Taking the OFDM-based wireless communication system as an example, the content of the control information includes: the terminal identity, the number of retransmissions, the CBB start carrier position of the data information, and the number of CBB carriers of the data information. For details, refer to FIG. 8B. FIG. 8B is a schematic diagram of control information when data information and control information are transmitted on different transmission resources in the transmission resource configuration method of the present invention.

Referring to FIG. 8B, the control information includes a terminal identity, a number of retransmissions, a CBB start carrier position of the data information, and a number of data information CBB carriers. Determining, by the access device, whether to perform hybrid automatic repeat request (HARQ merging) according to the identity identifier and the number of retransmissions; or determining whether to perform automatic retransmission request ARQ merging according to the identity identifier and the number of retransmissions; The starting carrier position of the first CBB and the number of carriers of the first CBB determine the size and location of the first CBB.

When the data information and the control information are transmitted on different transmission resources, since the CBB in the first CBB set is aligned in time with the CBB in the corresponding second CBB set, the information of the CBB in the CBB set of the control information does not need to be The location information of the CBB carrying the corresponding data information in the time domain only needs to carry the frequency domain information, that is, the data information CBB actually the carrier position and the number of data information CBB carriers.

After the access device sends the second indication information to the terminal, in the second CBB set, the location of at least one CBB in each CBB is demodulated to demodulate the control information, the control information. Carrying information of the target sub-CBB; the access device demodulates at the location of the target sub-CBB according to the information of the target sub-CBB to demodulate the data information. Specifically, the access device demodulates the CBB location of all possible control information, demodulates the content of the corresponding control information, and then demodulates the corresponding data information CBB according to the content of the control information according to the content of the control information, thereby solving Recall the data information. The access device can simultaneously demodulate data information transmitted on multiple non-orthogonal sub-CBBs using advanced receivers such as interference cancellation and joint detection.

In the foregoing transmission resource configuration method, the control information and the data information are separately transmitted on different contention resources. When the terminal penetration rate is low, even if the terminal has multiple capability levels, the capability level includes the modulation and coding mode and data supported by the terminal. Packet size, maximum transmit power, etc., but access The device only needs to allocate less contention-based resources to support multiple requirements of the terminal, and saves competition-based resources. As the penetration rate of the terminal increases, the access device can adjust the uplink according to the load information of each competing resource block. The transmission of competing resources increases the flexibility of utilization and allocation of content based on competition. At the same time, the access device separately analyzes the load of the control information and the data information, and can independently adjust the load of the control information and the data information by setting different load thresholds. Compared with the case where data information and control information are transmitted on the same transmission resource, it has better flexibility, can improve the overall demodulation performance of control information and data information, and improve resource utilization.

In the first case, the first CBB set configured by the access device for the terminal is not fixed, but can be adjusted. Similarly, in the second case, the second CBB set can also be adjusted. Specifically, referring to FIG. 9, FIG. 9 is a schematic diagram of a CBB adjustment process in the transmission resource configuration method of the present invention, including:

201. The access device allocates or adjusts the CBB set according to the service requirement and the load status of the terminal.

The access device periodically analyzes the load information of each CBB and each sub-CBB in the CBB set, including the number of users, the error rate, the demodulated SIR, and the service arrival rate. Based on this information, the access device adjusts the CBB collection.

202. The access device notifies the information of each CBB in the CBB set of the terminal and the information of each sub-CBB through broadcast, multicast, or dedicated signaling.

Specifically, the access device notifies the terminal of the CBB information, the information of each sub-CBB, and the load information in the adjusted CBB set, and the terminal selects the target sub-CBB in the adjusted CBB set to transmit the uplink information. For example, the access device adjusts the CBB set when the terminal accesses or the terminal exits, or periodically adjusts the CBB set, and notifies the terminal of the information of each CBB and each sub-CBB in the adjusted CBB set.

203. The access device analyzes the load status of each CBB in the CBB collection and the load status of each sub-CBB.

In this step, the access device analyzes the load status of each CBB in the CBB set and the load status of each sub-CBB, and returns to 201 to form a closed loop process.

In the foregoing steps 201-203, the CBB set may refer to the first CBB set, and may also refer to the second CBB set, and may also include the first CBB set and the second CBB set. For the first CBB set, according to the set. The load condition of each of the sub-CBBs is closed-loop adjusted, and for the second CBB set, the closed-loop adjustment is performed according to the load conditions of the CBBs in the set.

The above is a detailed description of the present invention from the perspective of resource allocation. Hereinafter, the present invention will be described in detail from the perspective of data transmission and the direction of transmission resource indication.

First, the angle of data transmission.

Specifically, the access device receives the uplink information sent by the terminal through the target sub-CBB, where the target sub-CBB is selected by the terminal from the first CBB set, and each CBB included in the first CBB set is orthogonal to each other. And each CBB is divided into one or more sub-CBBs; the position of each sub-CBB in the first CBB set is demodulated to demodulate the uplink information.

When the control information and the data information are transmitted in the same CBB, the terminal selects the target sub-CBB to send the data information and the control information from the first CBB set according to the capability of the terminal, the service requirement, and the first indication information sent by the base station; The network device demodulates the position of all possible sub-CBBs of the configured first CBB set to demodulate control information and data information, and the access network device can also simultaneously demodulate using advanced receivers such as interference cancellation and joint detection. Data transmission on multiple non-orthogonal CBBs and performing HARQ merging or not merging. In the process, the access device further configures the first CBB set for the terminal before receiving the uplink information sent by the terminal through the target sub-CBB; and sends the first indication information to the terminal, where the first indication information includes The information of each CBB in the first CBB set and the information of each sub-CBB are used to enable the terminal to select the target sub-CBB from the first CBB set according to the first indication information to transmit the Control information and the data information.

When the control information and the data information are transmitted in different CBBs, the terminal selects the target CBB transmission control information from the second CBB set according to the capability of the terminal, the service requirement, and the second indication information sent by the base station, and according to the capability and service requirement of the terminal. The first indication information sent by the base station and the target CBB transmission data information are selected from the first CBB set. The access network device demodulates at all possible second CBB locations configured to demodulate the control information and demodulate at the location of the target sub-CBB based on the control information to demodulate the data information. The access network device can also simultaneously demodulate data transmissions on multiple non-orthogonal CBBs using advanced receivers such as interference cancellation and joint detection, and perform HARQ combining or not. In the process, the access device configures the second CBB set for the terminal, and sends second indication information to the terminal, where the second indication information includes information about each CBB in the second CBB set, and is used by the access device. And causing the terminal to select the target CBB from the second CBB set according to the first indication information to transmit the control information; and then, receiving control information sent by the terminal through the target CBB, where the target CBB is The terminal is from the second Selected in the CBB set, each CBB included in the second CBB set is orthogonal to each other; and demodulated at positions of each of the CBBs in the second CBB set to demodulate the control information.

Optionally, in the foregoing embodiment, each CBB is orthogonal to each other, and includes at least one of the following: a time domain orthogonal, a frequency domain orthogonal, a codeword domain orthogonal, and a spatial orthogonal.

Optionally, in the foregoing embodiment, each of the sub-CBBs are orthogonal or non-orthogonal to each other.
