Description

^Source allocation method indication method, device and system

Technical field

The present invention relates to the field of mobile communications, and in particular, to a resource allocation mode indication method, apparatus, and system. BACKGROUND OF THE INVENTION In the third-generation partnership program (LTE), the system uses a centralized scheduling of base stations to control the transmission of Physical Uplink Shared Channel (PUSCH) of user equipment (User Equipment, UE).

The uplink scheduling information of the physical uplink shared channel PUSCH is sent by the base station to the target UE through a Physical Downlink Control Channel (PDCCH). The physical downlink control channel carries Downlink Control Information (DCI), including downlink or uplink scheduling information, and uplink transmit power control commands. According to different downlink control information, the LTE system defines multiple downlink control information formats (DCI formats). The uplink scheduling information of the physical shared channel PUSCH is carried in the downlink control information format 0 (DCI format 0). If the UE detects the PDCCH with the DCI format 0 format, according to the uplink scheduling information contained therein, the PUSCH is transmitted on the allocated channel resource by using the indicated modulation and coding mode and the corresponding transmit power.

In the LTE system, the physical uplink shared channel of multiple user terminals in the small area is frequency-division multiplexed with the uplink system bandwidth, that is, the PUSCHs of different UEs are orthogonal in the frequency domain. The base station indicates the radio channel resource allocated by the PUSCH of the target UE in DCI format 0.

LTE system uplink resource allocation (resource allocation) with resource blocks (Resource Block,

RB) is the unit. A resource block is used to describe a mapping of a physical channel (Physical Channel) to a resource element (Resource Element, RE). Two resource blocks are defined: Physical Resource Block (PRB) and Virtual Resource Block (VRB). Representing a physical resource block PRB contiguous subcarriers (subcarrier) in the frequency domain, representing _{the b} successive symbols in the time domain. Where N = 12 and the subcarrier spacing is 15 kHz, that is, the width of a PRB in the frequency domain is 180 kHz. For the normal cyclic prefix (Normal CP), 3⁄4 =7, for the extended cyclic prefix (Extended CP), 3⁄4 =6, that is, the length of a PRB in the time domain is one slot (slot, 0.5ms). Thus, one PRB includes N _b xN _s resource units. In a time slot, the PRB index in the frequency domain is " _PRB , where,

A is the number of PRBs corresponding to the bandwidth of the uplink system; the index pair of RE is where /t = o,..., AN _s -1 is the frequency domain index, / = o,..., N _b -i is the time domain Index, then

k

^W PRB takes the regular cyclic prefix as an example. The structure of PRB is shown in Figure 1.

A virtual resource block VRB has the same structure and size as the PRB. Two types of VRBs, a virtual resource blocks of distributed type and a virtual resource blocks of localized type (VRB) are defined. When resources are allocated, a pair of VRBs located in two slots in one subframe (frame) are allocated together, and a pair of VRBs have an index " _VRB ."

The centralized VRB maps directly to the PRB, ie

^PRB = ⁷⁷ VRB

The mapping of VRB to PRB is the same on two slots within one subframe.

The distributed VRB is mapped to the PRB according to certain rules.

Where =0,..., 19 is the slot number within a radio frame (frame, 10ms). The mapping of VRB to PRB is different on two slots within one subframe.

As shown in FIG. 2, in order to maintain the single carrier characteristic of the uplink signal, in the LTE system, the PUSCH uses a continuous resource allocation manner, that is, the PUSCH of one UE occupies a continuous bandwidth in the frequency domain. This bandwidth is part of the bandwidth of the entire uplink system, including a set of consecutive PRBs. The number of PRBs is TM ^SCH and the number of consecutive subcarriers included is

PUSCH _ PUSCH 3⁄4rRB

1 ^V1 sc ~ ^1V1 B ■ ^ ^V sc

The base station gives a Resource Indication Value in DCI format 0. RIV). The RIV indicates the starting position _start and length ^ of a group of consecutive VRBs according to the tree representation method, where _{START is} the index of the starting VRB in the continuous VRB of the group, and is the number of VRBs included in the continuous VRB of the group. The resource indication is "log ₂ (A (i + l)/2)] bits, which is the number of resource blocks corresponding to the uplink system bandwidth.

In the LTE system, the physical uplink shared channel is transmitted using a single antenna port.

The LTE-Advanced system (referred to as the LTE-A system) is a next-generation evolution system of the system. As shown in Figure 3, the LTE-A system uses carrier aggregation technology to extend the transmission bandwidth. Each aggregated carrier is called a component carrier. Multiple component carriers may be contiguous or non-contiguous, may be in the same frequency band, or may be in different frequency bands.

In the LTE-A system, the physical uplink shared channel of the user terminal within one component carrier may adopt a continuous or non-contiguous resource allocation manner. The so-called continuous resource allocation, that is, similar to the LTE system, the physical uplink shared channel of the user terminal occupies a continuous bandwidth in one component carrier; the so-called discontinuous resource allocation means that the physical uplink shared channel of the user terminal occupies within one component carrier. Multi-segment bandwidth, these bandwidths are non-contiguous, each segment of bandwidth contains a set of consecutive PRBs, called a cluster, as shown in Figure 4.

The uplink discontinuous resource allocation of the LTE-A system can refer to the downlink resource allocation of the LTE system. There are three resource allocation modes for LTE system downlink resource allocation, type 0, type 1 and type 2, where type 0 allocates channel resources in units of Resource Block Grou (RBG). RBG is defined as a set of consecutive PRBs, and the size of the resource block group P (RBG size, ie the number of resource blocks included in the resource block group) is a function of the system bandwidth. As shown in Table 3, the LTE system bandwidth can be configured to 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz, and the corresponding PRB numbers are 6, 15, 25, 50, 75, 100. According to different system bandwidths (represented by the corresponding PRB number A), the size of the resource block group is also different, that is, the granularity of resource allocation is different, as shown in Table 4.

Table 3 LTE system bandwidth

Resource block group size

Then, the number of resource block groups is

N.

. The index of the resource block group is 0,..., Λ _σ -1 in order of increasing frequency. Where, if N^ _m . dP = Q, then the size of each resource block group is; if N^m. When dP>0, the size of the previous LN^/P" resource block group is P, and the size of the last resource block group is

The resource allocation mode type 0 uses a bitmap (bit map) to indicate the allocated resource block group, and each resource block group from index 0 to N^-l sequentially corresponds to each bit from the highest bit to the lowest bit in the bitmap. A bit of 1 indicates that the corresponding resource block group is assigned to the target user terminal, and a value of 0 indicates that it is not assigned to the target user terminal.

The resource allocation mode type 1 uses a bitmap to indicate the allocated resource block in the resource block group (RBG subset, also called resource block subset) on the basis of type 0. It has the same signaling overhead as type 0.

In the research on uplink discontinuous resource allocation in LTE-A system, a variety of resource allocation methods for limiting the number of clusters are also proposed. For example, a resource allocation method that limits the number of clusters to 2, in units of resource blocks, resources. The overhead of allocating information is "log ₂ (i (i + l)/2)] +1 bit.

In addition, in the LTE-A system, the physical uplink shared channel can be transmitted by using a single antenna port or by using multiple antenna ports.

In summary, in the LTE system, there is only one resource allocation mode for the physical uplink shared channel, that is, a continuous resource allocation mode; in the LTE-A system, there is at least one of the physical uplink shared channel except the continuous resource allocation mode. Other resource allocation methods that support non-contiguous resource allocation.

Preferred embodiment of the invention

The invention will be described in detail below with reference to the embodiments and the accompanying drawings.

The present invention provides a method for indicating a resource allocation manner, in which a base station carries resource allocation mode indication information indicating a resource allocation manner in a downlink control information format (DCI format) for scheduling a physical uplink shared channel, and formats the downlink control information. Send to the target user terminal.

After receiving the downlink control information format, the target terminal determines a resource allocation manner used by the downlink control information format according to the resource allocation manner indication information included therein, and further reads the resource in the downlink control information format. Assign information.

First, the first embodiment of the present invention will be described with reference to the accompanying drawings.

In the LTE-A system, the uplink system bandwidth of one component carrier is represented by the corresponding PRB number A, and the base station transmits the single-antenna or multi-antenna port transmission of the user terminal through the downlink control information format. The physical uplink shared channel transmits uplink data. A first embodiment of the present invention provides a method for indicating a resource allocation manner. The process for completing the indication of a terminal resource allocation manner by using the method is as shown in FIG. 5, and includes:

Step 501: The base station constructs a downlink control information format, and carries, in the downlink control information format, resource allocation mode indication information indicating a resource allocation manner;

In the embodiment of the present invention, the resource allocation mode indication information is specifically a resource allocation mode indication bit, and the resource allocation mode indication bit is 1 bit, and the resource allocation mode indication bit has 0 and 1 values, respectively representing continuous resource allocation. Mode and other resource allocation modes. Other resource allocation modes are one or more resource allocation modes that support non-contiguous resource allocation, such as resource allocation mode type 0 or type l.

Optionally, the resource allocation mode indication bit "0" represents a continuous resource allocation mode, and the resource allocation mode indication bit "1" represents another resource allocation mode (one or more resource allocation modes supporting non-contiguous resource allocation) You can also use the resource allocation mode to indicate that the bit "1" represents the continuous resource allocation mode, and the resource allocation mode indicates that the bit "0" represents other resource allocation modes. Embodiments of the Invention The former is explained by way of example.

The downlink control information format also carries resource allocation information.

When the resource allocation mode indication bit is 0, that is, the continuous resource allocation mode, the resource allocation information is specifically resource block allocation information, and the length of the information is “log ₂ (A (i + l) / 2)] Bit, used to indicate the allocated resource block.

When the resource allocation mode indication bit is 1, that is, one or more resource allocation modes that support non-contiguous resource allocation, the resource allocation information is used to indicate a specific resource allocation of the terminal. For example, the resource allocation information includes a resource allocation header and a resource block assignment, and the resource allocation header is 1-bit information, which is used to further distinguish the resource allocation modes type 0 and type 1 , and the type 0 resource allocation header. A value of 0 means that type 1 is represented by 1. When the resource allocation mode is type 0, the resource block is allocated as "N bits, which is used to indicate the allocated resource block group; when the resource allocation mode is type 1, the "i / P" bit allocated by the resource block includes three parts. They are: "log ₂ 0P) bit as the header of the resource allocation type type 1 to indicate the selected resource. 1 bit, used to indicate whether the resource allocation span is shifted in the selected subset of resource blocks, and a value of 1 indicates a shift trigger, and a value of 0 indicates that the shift is not triggered;

A / ^ _ "log ₂ (P)] - l bit, used to indicate the allocated resource block. Optionally, if the uplink system bandwidth of the component carrier is less than or equal to 10 physical resource blocks, the resource allocation may be ignored. Header, the default resource allocation method type 0.

The resource allocation modes type 0 and type 1 are the downlink resource allocation modes of the LTE system, type 0 and type 1, respectively.

The resource block group size P (RBG size, that is, the number of resource blocks included in the resource block group) depends on the uplink system bandwidth A of the component carrier, as shown in Table 5.

table 5

Step 502: The base station sends the downlink control information format to the terminal, and uses the resource allocation mode indicated by the resource allocation mode indication information to schedule the physical uplink shared channel corresponding to the terminal.

At this time, the resource block group size ^ depends on the uplink system bandwidth A of the component carrier, as shown in Table 5. Next, a second embodiment of the present invention will be described.

The base station transmits the uplink data by scheduling the physical uplink shared channel transmitted by the single-antenna or multi-antenna port of the user terminal through the downlink control information format.

In the embodiment of the present invention, the resource allocation mode indication information is specifically a cyclic redundancy check (CRC) mask (MASK). Specifically, the CRC is added to the CRC of the downlink control information format to indicate the scheduled The resource allocation mode of the physical uplink shared channel. You can add a mask to the CRC when you choose to use the continuous resource allocation method, or you can add a mask to the CRC when you choose to use other resource allocation methods, such as one or more resource allocation methods that support non-contiguous resource allocation.

The overhead of the resource allocation information in the downlink control information format is a "log ₂ (A (i + 1)/2)] bit, which is used to indicate the allocated resource block.

When the resource allocation mode is other resources, the overhead of the resource allocation information in the downlink control information format is “1 _0§2 (^(^ + 1)/2)]+1 bits, which is used to indicate the allocated resource block group. The resource block group size depends on the uplink system bandwidth N of the component carrier, as shown in Table 5.
