Description

一种实现资源分配的方法和装置Method and device for realizing resource allocation 技术领域Technical field
本申请涉及但不限于无线通信领域，尤指一种实现资源分配的方法和装置。The present application relates to, but is not limited to, the field of wireless communications, and more particularly to a method and apparatus for implementing resource allocation.
背景技术Background technique
机器类型通信(MTC，Machine Type Communication)用户终端(UE，User Equipment)，又称机器到机器(M2M，Machine to Machine)UE，是目前物联网的主要应用形式。Machine Type Communication (MTC) User Equipment (UE), also known as Machine to Machine (M2M), is the main application form of the Internet of Things.
近年来，由于长期演进(LTE，Long-Term Evolution)/高级长期演进系统(LTE-A，Long-Term Evolution Advance)的频谱效率高，越来越多的移动运营商选择LTE/LTE-A作为带宽无线通信系统的演进方向。基于LTE/LTE-A的MTC多种类数据业务也将更具吸引力。In recent years, due to the high spectrum efficiency of Long-Term Evolution (LTE)/Long-Term Evolution Advance (LTE-A), more and more mobile operators choose LTE/LTE-A as the The evolution direction of bandwidth wireless communication systems. MTC multi-class data services based on LTE/LTE-A will also be more attractive.
MTC设备通常是低成本的设备，具有支持的射频(RF，Radio Frequency)带宽比较小、单接收天线等特征，其发送和接收带宽一般为1.4兆赫兹(MHz)。有一类MTC设备，比如电表等，可能被放置在地下室的铁皮柜中，覆盖非常差，第三代合作伙伴(3GPP，3rd Generation Partnership Project)在版本12和13中为低成本和需要覆盖增强的MTC UE提供解决方案，目前针对覆盖增强的解决方案是通过对某些信道的大量重复来提升覆盖的。MTC devices are usually low-cost devices with features such as a small RF (Radio Frequency) bandwidth and a single receive antenna. The transmit and receive bandwidths are typically 1.4 megahertz (MHz). MTC has a class of devices, such as meters and the like, may be placed in the basement of the cupboard, the cover is very poor, the Third Generation Partnership (3GPP, 3 rd Generation Partnership Project ) release 12 and the cover 13 and the need for low cost enhancement The MTC UE provides a solution, and the current solution for coverage enhancement is to improve coverage by a large number of repetitions of certain channels.
在LTE系统中，基站需要为UE分配资源，UE根据基站分配的资源来发送物理上行共享信道(PUSCH，Physical Uplink Shared Channel)或者接收物理下行共享信道(PDSCH，Physical Downlink Shared Channel)。相关的实现资源分配的方法大致包括：基站通过下行控制信息(DCI，Downlink Control Information)在系统带宽的全带宽下为UE分配资源，其中，DCI中的资源分配域为表示分配给UE的资源的信息。然而，对于支持带宽较小的MTC UE来说，eNB分配给UE的资源只能限制在一个带宽小于系统带宽的窄带中，如果采用上述的资源分配方法，DCI中资源分配域所占用的比特数较多，资 源分配的开销较大，对于覆盖增强下的UE是不能接受的。In the LTE system, the base station needs to allocate resources to the UE, and the UE sends a Physical Uplink Shared Channel (PUSCH) or a Physical Downlink Shared Channel (PDSCH) according to the resources allocated by the base station. The related method for realizing resource allocation generally includes: the base station allocates resources to the UE under the full bandwidth of the system bandwidth by using Downlink Control Information (DCI), where the resource allocation field in the DCI is a resource indicating the resource allocated to the UE. information. However, for an MTC UE that supports a small bandwidth, the resources allocated by the eNB to the UE can only be limited to a narrowband whose bandwidth is smaller than the system bandwidth. If the resource allocation method described above is used, the number of bits occupied by the resource allocation domain in the DCI is used. More, capital The overhead of source allocation is large, which is unacceptable for UEs with coverage enhancement.

演进的节点B(eNB，Evolved Node B)分配给UE的资源为k1个RBG，其中，k1个RBG的频域跨度小于或等于M个PRB，也就是说k1个RBG的频率最低的PRB到频率最高的PRB之间的PRB的个数小于或等于M，比如M＝6，RBG的大小为4时，只能分配1个RBG。其中，k1为正整数。The resources allocated to the UE by the evolved Node B (eNB, Evolved Node B) are k1 RBGs, wherein the frequency domain span of the k1 RBGs is less than or equal to M PRBs, that is, the PRB to the lowest frequency of the k1 RBGs. The number of PRBs between the highest PRBs is less than or equal to M, such as M=6. When the size of the RBG is 4, only one RBG can be allocated. Where k1 is a positive integer.
可选地，可以规定k1≤K1，K1为eNB和UE预先设置，或者由eNB预先设置后发送给UE。Optionally, k1 ≤ K1 may be specified, where K1 is preset for the eNB and the UE, or is preset by the eNB and then sent to the UE.
分配的k1个RBG可以是连续的，也可以是不连续的。一个系统只能选择其中的一种方式。The allocated k1 RBGs may be continuous or discontinuous. A system can only choose one of them.
分配给UE的RBG为可用资源的RBG，也可以是至少有一个PRB在可用资源内的RBG。至少有一个PRB在可用资源内的RBG是指：分配给UE的RBG中，RBG的部分PRB在可用资源内，部分PRB在可用资源外，比如RBG大小为4，有一个RBG的1个PRB在可用资源内，有3个PRB在可用资源外，那么这个RBG也可以分配给UE。 The RBG allocated to the UE is an RBG of available resources, or may be an RBG in which at least one PRB is within an available resource. The RBG of the at least one PRB in the available resources refers to: in the RBG allocated to the UE, part of the PRB of the RBG is in the available resources, part of the PRB is outside the available resources, for example, the RBG size is 4, and one PRB of one RBG is in the RBG. Within the available resources, there are 3 PRBs outside the available resources, then this RBG can also be allocated to the UE.
可用资源可以是eNB和UE预设的，比如预设为系统带宽，那么分配给UE的一个或者多个RBG可以是系统带宽中RBG；可用资源也可以预设为系统带宽中的一部分频域资源，比如20MHz的系统可以预设为最中间的20个PRB，或者预设为频域位置固定的4个窄带，每个窄带包含的PRB大小为M，分配给UE的RBG为部分频域资源内的RBG，或者为部分PRB在可用资源内的RBG。The available resources may be preset by the eNB and the UE, for example, the system bandwidth is preset, and then one or more RBGs allocated to the UE may be RBGs in the system bandwidth; the available resources may also be preset as part of the frequency bandwidth resources in the system bandwidth. For example, a 20 MHz system can be preset to the most intermediate 20 PRBs, or preset to 4 narrowbands with fixed frequency domain positions. Each narrowband contains a PRB size of M, and the RBG allocated to the UE is part of the frequency domain resource. RBG, or RBG for some PRBs within available resources.
可用资源也可以是eNB预先设置后发送给UE的，比如eNB在系统信息块(SIB，System Information Block)中通知UE的可用RBG索引的范围。The available resources may also be sent to the UE after being set by the eNB. For example, the eNB notifies the UE of the range of available RBG indexes in a System Information Block (SIB).
假设M＝6，系统带宽为20MHz，假设可用资源为系统带宽上的所有RBG，由于20MHz系统带宽的RBG大小为4，而M为6，最多只能给UE分配1个RBG，那么可以分配的RBG数量为100/4＝25个。因此，系统至少需要

表示向上取整。Assume that M=6, the system bandwidth is 20MHz, assuming that the available resources are all RBGs on the system bandwidth, since the RBG size of the 20MHz system bandwidth is 4, and M is 6, and only one RBG can be allocated to the UE at most, then it can be allocated. The number of RBGs is 100/4=25. Therefore, the system needs at least

或者，假设系统带宽为10MHz，M＝6，假设可用资源为系统带宽上的所有RBG，由于10MHz系统带宽的RBG大小为3，而UE支持的最大带宽为6，最多可以给UE分配1个RBG或者2个RBG，若分配1个RBG，可能的资源分配有17种，若分配2个RBG，可能的资源分配有16种，因此，系统至少需要

Or two RBGs. If one RBG is allocated, there are 17 possible resource allocations. If two RBGs are allocated, there are 16 possible resource allocations. Therefore, the system needs at least

或者，假设系统带宽为5MHz，M＝6，假设可用资源为系统带宽上的所有RBG，由于5MHz系统带宽的RBG大小为2，而M为6，最多可以给UE分配1个RBG或者2个RBG或者3个RBG，假设eNB只给UE分配连续的资源，那么若分配1个RBG，可能的资源分配有13种，若分配2个RBG，可能的资源分配有12种，若分配3个RBG，可能的资源分配有11种。因此，系统至少需要

Or 3 RBGs. If the eNB allocates only contiguous resources to the UE, if there are 1 RBG allocated, there are 13 possible resource allocations. If 2 RBGs are allocated, 12 possible resource allocations. If 3 RBGs are allocated, There are 11 possible resource allocations. Therefore, the system needs at least

前面是几个可用资源为系统带宽上的所有RBG的例子，这里举一个可用资源为系统带宽上的若干个窄带的例子，假设系统带宽为5MHz，M＝6，可用的窄带为两个窄带，比如为PRB索引为0～5和PRB索引为10～15的窄带，其中包含的RBG一共有6个，如果eNB只给UE分配资源，那么至少需要
Figure PCTCN2016078328-appb-000006
个比特来为UE指示分配的资源。The foregoing is an example of several available resources for all RBGs on the system bandwidth. Here is an example of available resources as several narrowbands on the system bandwidth. Suppose the system bandwidth is 5MHz, M=6, and the available narrowband is two narrowbands. For example, a narrowband with a PRB index of 0 to 5 and a PRB index of 10 to 15 includes a total of six RBGs. If the eNB only allocates resources to the UE, then at least
Figure PCTCN2016078328-appb-000006
The bits are used to indicate the allocated resources for the UE.
eNB确定了需要分配给UE的资源之后，会发送表示分配给UE的资源 的信息给UE，表示分配给UE的资源的信息通常是一组二进制的比特，通常，表示分配给UE的资源的信息包含在eNB调度UE的DCI中，实际应用中不限于这种方式。在给出如何配置表示分配给UE的资源的信息之前，首先介绍RBG索引的概念，RBG索引可以是相关协议中规定好的RBG索引，为从零开始的整数；RBG索引也可以是将可用资源内的所有RBG重新编号后的索引，比如上述可用资源为两个窄带的例子中，一共有6个可以分配的RBG，可以按照从频率最低到最高的顺序得到RBG的索引分别为0、1、2、3、4和5，后者资源指示开销可能会小一些。After the eNB determines the resources that need to be allocated to the UE, it sends a resource indicating that it is allocated to the UE. The information to the UE indicates that the information of the resources allocated to the UE is usually a set of binary bits. Generally, the information indicating the resources allocated to the UE is included in the DCI of the eNB scheduling UE, and the actual application is not limited to this manner. Before giving information on how to configure the resources allocated to the UE, the concept of the RBG index is first introduced. The RBG index may be an RBG index specified in the relevant protocol, which is an integer from zero; the RBG index may also be an available resource. For all the RBG renumbered indexes, for example, the above available resources are two narrowband examples. There are 6 RBGs that can be allocated. The indexes of the RBGs can be 0, 1, respectively, in the order from the lowest frequency to the highest. 2, 3, 4, and 5, the latter resource indication overhead may be smaller.
在下面配置表示分配给UE的资源的信息的方法的介绍中，RBG索引可以是上述方式中的一种。In the following description of a method of configuring information indicating resources allocated to a UE, the RBG index may be one of the above.
第一种配置表示分配给UE的资源的信息的方法：The first method of indicating the information of the resources allocated to the UE:
配置表示分配给UE的资源的信息的方式可以采用两个域的形式，第一个域指示分配的RBG的个数，比如1个RBG则为“0”，2个RBG则为“1”，第二个域指示分配的具体是哪k1个RBG。下面分两种情况具体来介绍，即分配给所有UE的资源均是连续的，分配给不同UE的资源可以是连续的，也可以是不连续的。The method of configuring the information indicating the resources allocated to the UE may be in the form of two domains. The first field indicates the number of allocated RBGs, for example, one RBG is “0” and two RBGs are “1”. The second field indicates which k1 RBGs are allocated. The following two cases are specifically introduced, that is, resources allocated to all UEs are continuous, and resources allocated to different UEs may be continuous or discontinuous.
一、分配给所有UE的资源均是连续的。1. The resources allocated to all UEs are continuous.
第二个域为分配的k1个RBG的起始RBG的索引。The second field is the index of the starting RBG of the allocated k1 RBGs.
以M＝6，系统带宽为5MHz，可用资源为整个系统带宽为例，第一个域采用2比特(bit)来指示分配的是1个RBG，还是2个RBG，还是3个RBG，分别用“00”、“01”、“10”表示，第二个域采用4bit来指示分配的RBG的起始位置，以指示是哪个RBG或者哪两个连续RBG或者哪三个连续RBG。举例说明，假设分配给UE的是索引为5和6的RBG，即起始RBG索引为5，那么eNB发送给UE的表示分配给UE的资源的信息为“010101”。图3为分配资源的示意图。如图3所示，分配给UE的索引为5和6的RBG如图中点状部分所示。Take M=6, the system bandwidth is 5MHz, and the available resources are the whole system bandwidth. For example, the first field uses 2 bits to indicate whether 1 RBG, 2 RBGs, or 3 RBGs are allocated. "00", "01", and "10" indicate that the second field uses 4 bits to indicate the starting position of the allocated RBG to indicate which RBG or which two consecutive RBGs or which three consecutive RBGs. For example, it is assumed that the RBGs with the indexes of 5 and 6 are allocated to the UE, that is, the initial RBG index is 5, and the information that the eNB sends to the UE indicating the resources allocated to the UE is “010101”. Figure 3 is a schematic diagram of allocating resources. As shown in FIG. 3, the RBGs assigned to the UE with indices of 5 and 6 are shown in the dotted portion of the figure.
对于分配给UE的RBG的个数只有一个的情况，两个域的资源分配方法只包含第二个域。 In the case where there is only one RBG allocated to the UE, the resource allocation method of the two domains includes only the second domain.
比如，以M＝6，系统带宽为20MHz，RBG数目为25个，可用资源为整个系统带宽为例，这种情况下没有第一个域，只有第二个域，假设分配给UE的是索引为8的RBG，那么eNB发送给UE的表示分配给UE的资源的信息为“01000”。For example, with M=6, the system bandwidth is 20MHz, and the number of RBGs is 25. The available resources are the whole system bandwidth. In this case, there is no first domain, only the second domain, and the index assigned to the UE is assumed. The RBG of 8 is the information that the eNB sends to the UE indicating that the resource allocated to the UE is "01000".
二、分配给不同UE的资源可以是连续的，也可以是不连续的。2. Resources allocated to different UEs may be continuous or discontinuous.
第二个域包括两部分：第一部分为分配的k1个RBG的起始RBG的索引，第二部分为起始RBG之后的若干个RBG索引对应的RBG的bitmap，比如bitmap的bit数为
Figure PCTCN2016078328-appb-000007
，其中，
Figure PCTCN2016078328-appb-000008
为向下取整，S为RBG的大小，当
Figure PCTCN2016078328-appb-000009
时，只有第一部分。比如以M＝6，系统带宽为20MHz，可用资源为整个带宽为例，假设分配的是RBG索引5和7，那么第二个域的第一部分为起始位置的索引，即“0101”，第二部分为RBG#6和7的bitmap，即为“01”，那么第二个域的bit为：“010101”。The second field includes two parts: the first part is an index of the initial RBG of the allocated k1 RBGs, and the second part is a bitmap of the RBG corresponding to the RBG indexes after the starting RBG, for example, the bit number of the bitmap is
Figure PCTCN2016078328-appb-000007
,among them,
Figure PCTCN2016078328-appb-000008
To round down, S is the size of the RBG, when
Figure PCTCN2016078328-appb-000009
When, only the first part. For example, if M=6, the system bandwidth is 20MHz, and the available resources are the whole bandwidth as an example, if the RBG indexes 5 and 7 are allocated, then the first part of the second domain is the index of the starting position, that is, “0101”, The second part is the bitmap of RBG# 6 and 7, which is “01”, then the bit of the second field is “010101”.
第二种配置表示分配给UE的资源的信息的方法：The second configuration represents a method of information of resources allocated to the UE:
在该指示方法中，指示信息只有一个域，分配给UE的资源和一个RIV值对应，RIV的值是分配的RBG的索引的函数，比如假设分配的资源都是连续的，那么当分配的是1个RBG时，RIV＝起始RBG索引，当分配的是2个RBG时，RIV＝m+起始RBG的索引，其中，m为分配给UE的RBG的个数，其中的RBG索引如上述。In the indication method, the indication information has only one domain, the resource allocated to the UE corresponds to a RIV value, and the value of the RIV is a function of the index of the allocated RBG, for example, if the allocated resources are all continuous, then when the allocation is When 1 RBG, RIV=initial RBG index, when 2 RBGs are allocated, RIV=m+ index of starting RBG, where m is the number of RBGs allocated to the UE, where the RBG index is as described above.
第三种配置表示分配给UE的资源的信息的方法：A third configuration method of indicating information of resources allocated to the UE:
该指示方法是基于窄带的资源指示方法，采用两个域指示，第一个域指示分配的是哪个窄带，第二个域指示分配的是窄带中的哪些资源。比如可用资源为若干个窄带，第一个域用于指示分配的窄带的索引，第二个域用于指示分配的窄带内的哪些RBG。窄带的索引可以是按照预设的方式将系统带宽划分后得到的索引，比如系统带宽为20MHz时，假设从PRB#0开始每6个PRB划分成一个窄带，一共可以划分为17个窄带，索引为0～16，或者也可以是将可用资源按照预设的方式划分成的若干个窄带后得到的从0开始的索引。比如可用资源内一共有4个窄带，索引为0、1、2、3，每个窄带有2个RBG，索引为0，1，分配给UE的是第2个窄带的第2个RBG，那么第一个 域为“10”，第二个域用2bit的bitmap指示分配的RBG，即“01”。The indication method is based on a narrowband resource indication method, using two domain indications, the first domain indicating which narrowband is allocated, and the second domain indicating which resources in the narrowband are allocated. For example, the available resources are a number of narrowbands, the first field is used to indicate the index of the allocated narrowband, and the second field is used to indicate which RBGs in the allocated narrowband. The narrowband index may be an index obtained by dividing the system bandwidth according to a preset manner. For example, when the system bandwidth is 20 MHz, it is assumed that every 6 PRBs are divided into a narrow band from PRB#0, and a total of 17 narrowbands can be divided into indexes. It is 0 to 16, or it may be an index starting from 0 after a number of narrowbands in which the available resources are divided into a preset manner. For example, there are 4 narrowbands in the available resources, the index is 0, 1, 2, 3, each with 2 RBGs, the index is 0, 1, and the second RBG of the second narrowband is allocated to the UE, then First The field is "10", and the second field indicates the allocated RBG with a 2-bit bitmap, that is, "01".
又比如可用资源为整个系统带宽或者系统带宽中的部分频域资源，可以将可用资源按照预设的方式划分为多个由N个PRB组成的窄带，然后仍然可以采用上述的方法进行指示。其中，N为大于或等于1的整数。For example, the available resources are the whole system bandwidth or part of the frequency domain resources in the system bandwidth, and the available resources may be divided into a plurality of narrow bands composed of N PRBs according to a preset manner, and then the foregoing method may still be used for indication. Where N is an integer greater than or equal to 1.
实际应用中不限于上述举例。The actual application is not limited to the above examples.
第二实施例Second embodiment
假设UE支持的最大带宽对应的PRB个数为M，或者UE具有接收更大带宽的能力，但其应用受到某种限制，只能接收最多M个PRB，或者系统带宽为非规则系统带宽，如：7MHz、8MHz、12MHz、17MHz、22MHz等，而UE只能接收相关技术中的规范带宽，如：5MHz、10MHz、15MHz、20MHz，那么M为小于系统带宽的某一个规范带宽对应的PRB个数，实际应用中不限于这些场景。It is assumed that the maximum number of PRBs supported by the UE is M, or the UE has the capability of receiving a larger bandwidth, but its application is limited to only receive a maximum of M PRBs, or the system bandwidth is an irregular system bandwidth, such as : 7MHz, 8MHz, 12MHz, 17MHz, 22MHz, etc., and the UE can only receive the standard bandwidth in the related technology, such as: 5MHz, 10MHz, 15MHz, 20MHz, then M is the number of PRBs corresponding to a certain specification bandwidth of the system bandwidth. In practice, it is not limited to these scenarios.
本实施例中，eNB分配给UE的资源为k2个子RBG。其中，子RBG由RBG的部分PRB组成。比如子RBG是指将一个RBG分成多个块，例如将一个包含4个PRB的RBG平均分成两个子RBG，每个子RBG包含两个PRB，或者将包含4个PRB的RBG分成两个子RBG，一个子RBG包含3个连续的PRB，另一个子RBG包含一个PRB。对于一个系统来说，子RBG的划分可以是预设的，比如当RBG大小为4时，固定将4个PRB的RBG划分为两个包含2个PRB的子RBG，也可以是eNB预先设置好划分方式，然后发送给UE的。其中，k2个子RBG的频域跨度不大于M个PRB。k2为正整数。分配给所有UE的子RBG可以是均为连续的，也可以是连续或者不连续的，一个系统只能选择其中的一种方式。In this embodiment, the resources allocated by the eNB to the UE are k2 sub-RBGs. The sub-RBG is composed of a partial PRB of the RBG. For example, the sub-RBG is divided into multiple blocks, for example, an RBG including four PRBs is equally divided into two sub-RBGs, each sub-RBG includes two PRBs, or an RBG including four PRBs is divided into two sub-RBGs, one The sub-RBG contains 3 consecutive PRBs, and the other sub-RBG contains one PRB. For a system, the division of the sub-RBGs may be preset. For example, when the RBG size is 4, the RBGs of the four PRBs are fixed into two sub-RBGs including two PRBs, or may be preset by the eNB. Divide the way and then send it to the UE. The frequency domain span of the k2 sub-RBGs is not greater than the M PRBs. K2 is a positive integer. The sub-RBGs allocated to all UEs may be continuous or continuous or discontinuous, and one system can only select one of them.
可选地，可以规定k2≤K2，其中，K2为eNB和UE预先设置，或者由eNB预先设置，然后发送给UE的正整数。Alternatively, k2 ≤ K2 may be specified, where K2 is a preset integer set by the eNB and the UE, or preset by the eNB, and then sent to the UE.
eNB指示资源分配的方式与实施例一类似，其中，子RBG的索引可以是将系统带宽内的所有子PRB按照从频率最低到最高的顺序排序得到的索引，比如20MHz的系统带宽一共有25个RBG，每个RBG又分成2个子RBG，那么按照从频率最低到最高的顺序子RBG的索引分别为0、1、2……，49。 子RBG的索引也可以是可用资源内的索引。The manner in which the eNB indicates the resource allocation is similar to that in the first embodiment. The index of the sub-RBG may be an index obtained by sorting all sub-PRBs in the system bandwidth in order from lowest frequency to highest frequency, for example, a total of 25 system bandwidths of 20 MHz. RBG, each RBG is further divided into two sub-RBGs, and the indexes of the sub-RBGs in the order from the lowest frequency to the highest are 0, 1, 2, ..., 49, respectively. The index of the child RBG may also be an index within the available resources.
第三实施例Third embodiment
假设UE支持的最大带宽对应的PRB个数为M，或者UE具有接收更大带宽的能力，但其应用受到某种限制，只能接收最多M个PRB，或者系统带宽为非规则系统带宽，如：7MHz、8MHz、12MHz、17MHz、22MHz等，而UE只能接收相关技术中的规范带宽，如：5MHz、10MHz、15MHz、20MHz，那么M为小于系统带宽的某一个规范带宽对应的PRB个数，实际应用中不限于这些场景。It is assumed that the maximum number of PRBs supported by the UE is M, or the UE has the capability of receiving a larger bandwidth, but its application is limited to only receive a maximum of M PRBs, or the system bandwidth is an irregular system bandwidth, such as : 7MHz, 8MHz, 12MHz, 17MHz, 22MHz, etc., and the UE can only receive the standard bandwidth in the related technology, such as: 5MHz, 10MHz, 15MHz, 20MHz, then M is the number of PRBs corresponding to a certain specification bandwidth of the system bandwidth. In practice, it is not limited to these scenarios.
本实施例中，eNB分配给UE的资源为k3个RBG和k4个子RBG，其中，子RBG由RBG的部分PRB组成。其中，k3个RBG和k4个子RBG的频域跨度不大于M。In this embodiment, the resources allocated by the eNB to the UE are k3 RBGs and k4 sub-RBGs, where the sub-RBGs are composed of partial PRBs of the RBGs. The frequency domain span of k3 RBGs and k4 sub-RBGs is not greater than M.
可选地，可以规定k3≤K3，k4≤K4，其中，K3、K4为eNB和UE预先设置，或者由eNB预先设置，然后发送给UE的正整数。Alternatively, k3 ≤ K3, k4 ≤ K4 may be specified, where K3, K4 are preset for the eNB and the UE, or are preset by the eNB, and then sent to the UE.
可选地，子RBG由不属于可用资源中的任意一个RBG的一个或者多个PRB组成。图4为子RBG由不属于可用资源中的任意一个RBG的一个或者多个PRB组成的示意图。如图4所示，可用资源为系统资源中的一部分频域资源，系统中的RBG大小为4，在可用资源的两端有2个可以分配给UE的子RBG，如斜线部分所示。那么一共有4个可以分配给UE的RBG和2个可以分配给UE的子RBG，其中，子RBG的大小可以是不同的。Optionally, the sub-RBG consists of one or more PRBs that are not part of any of the available resources. 4 is a schematic diagram of a sub-RBG consisting of one or more PRBs that are not part of any of the available resources. As shown in FIG. 4, the available resource is a part of the frequency domain resource in the system resource, and the RBG size in the system is 4, and there are two sub-RBGs that can be allocated to the UE at both ends of the available resource, as shown by the slash portion. Then there are a total of 4 RBGs that can be allocated to the UE and 2 sub-RBGs that can be allocated to the UE, wherein the size of the sub-RBGs can be different.
图5为子RBG由不属于可用资源中的任意一个RBG的一个或者多个PRB组成的另一种示意图。如图5所示，可用资源为3个窄带，每个窄带的PRB个数为M＝6，系统中的RBG大小为4，一共有3个可以分配给UE的RBG和4个可以分配给UE的子RBG(如斜线部分所示)，其中，每个子RBG大小可以是不同的。FIG. 5 is another schematic diagram of a sub-RBG consisting of one or more PRBs that are not part of any of the available resources. As shown in FIG. 5, the available resources are three narrowbands, the number of PRBs in each narrowband is M=6, and the RBG size in the system is 4. There are three RBGs that can be allocated to the UE and four can be allocated to the UE. Sub-RBGs (as indicated by the shaded portion), where each sub-RBG size can be different.
可选地，子RBG由不属于窄带中的任意一个RBG的一个或者多个PRB组成，窄带是指将可用资源按照预设的方式划分成的由一个或一个以上PRB组成的窄带。图6为子RBG由不属于窄带中的任意一个RBG的一个或者多个PRB组成的示意图。如图6所示，可用资源划分成了4个窄带，每个窄带 中都有一个子RBG。Optionally, the sub-RBG is composed of one or more PRBs that do not belong to any one of the narrowbands, and the narrowband refers to a narrowband composed of one or more PRBs that divide the available resources into a preset manner. 6 is a schematic diagram of a sub-RBG consisting of one or more PRBs that do not belong to any one of the narrowbands. As shown in Figure 6, the available resources are divided into four narrow bands, each narrow band. There is a sub RBG in it.
下面介绍eNB进行资源指示的方式。比如将可用资源内的所有子RBG和RBG按照频率从最低到最高的顺序进行排序，例如图4中两个子RBG的索引为0和5，4个RBG的索引1、2、3、4，然后按照类似实施例一的方式进行资源分配指示。实施例一中的方式一和二都是基于索引的指示方式，可以将上述子RBG或者RBG的索引采用类似的方式进行指示。The manner in which the eNB performs resource indication is described below. For example, all sub-RBGs and RBGs in the available resources are sorted according to the frequency from lowest to highest. For example, the index of two sub-RBGs in FIG. 4 is 0 and 5, and the indexes of 4 RBGs are 1, 2, 3, and 4, and then The resource allocation indication is performed in a manner similar to the first embodiment. The first and second modes in the first embodiment are based on the indication manner of the index, and the index of the foregoing sub-RBG or RBG may be indicated in a similar manner.
对于图5中的情形，可以按照实施例一中的第三种资源分配方式进行指示，一共有3个窄带，需要2bit来指示窄带信息，每个窄带中最多有3个资源块，包括RBG和子RBG，那么也需要3bit来指示分配的是窄带中的哪些资源。图6也可以按照类似的方式进行指示，一共4个窄带，需要2个bit来指示分配的资源所在的窄带，每个窄带需要2bit来指示分配的RBG和/或子RBG。For the scenario in FIG. 5, the third resource allocation manner in Embodiment 1 may be used to indicate that there are 3 narrowbands, 2 bits are required to indicate narrowband information, and there are at most 3 resource blocks in each narrowband, including RBGs and sub-bands. RBG, then 3bit is also needed to indicate which resources are allocated in the narrowband. Figure 6 can also be indicated in a similar manner, a total of 4 narrowbands, requiring 2 bits to indicate the narrowband in which the allocated resources are located, and each narrowband requires 2 bits to indicate the assigned RBG and/or sub-RBG.
第四实施例Fourth embodiment
eNB分配的资源与第一实施例至第三实施例类似，不同的是指示方法有所不同。部分信息由调度UE的下行控制信道的预设信息表示，所述下行控制信道可以是PDCCH，也可以是EPDCCH，也可以是新定义的一种承载下行控制信息的下行控制信道。所述预设信息可以是调度该PUSCH/PDSCH的下行控制信道的聚合等级或者重复次数或者控制信道占用的资源或者传输模式等。The resources allocated by the eNB are similar to those of the first embodiment to the third embodiment, except that the indication methods are different. The part of the information is represented by the preset information of the downlink control channel of the scheduling UE. The downlink control channel may be a PDCCH, or may be an EPDCCH, or may be a newly defined downlink control channel carrying downlink control information. The preset information may be an aggregation level or a repetition number of a downlink control channel for scheduling the PUSCH/PDSCH, or a resource or a transmission mode occupied by the control channel.
比如聚合等级和表示分配给UE的资源的信息的部分信息有表2中所示的对应关系：For example, the aggregation level and the partial information indicating the information of the resources allocated to the UE have the correspondence shown in Table 2:
聚合等级Aggregation level 分配的资源Allocated resources
44 1个RBG1 RBG
88 2个RBG2 RBGs
1616 3个RBG3 RBGs
表2Table 2
具体分配的是哪1/2/3个RBG在DCI的资源分配域中通知，也就是说，对于实施例一中第一种配置表示分配给UE的资源的信息的方法来说，第一 个域采用调度UE的PDCCH的预设信息表示，第二个域在DCI的资源分配域中通知。或者对于实施例一中第三种配置表示分配给UE的资源的信息的方法，采用调度UE的PDCCH的预设信息表示分配给UE的资源所在的窄带，分配的具体是所述窄带中的哪些资源在DCI的资源分配域中通知。Specifically, which 1/2/3 RBGs are allocated in the resource allocation domain of the DCI, that is, for the first configuration in Embodiment 1, the information indicating the resources allocated to the UE, the first The domain is represented by preset information of the PDCCH scheduling the UE, and the second domain is notified in the resource allocation domain of the DCI. Or the method for indicating the information of the resource allocated to the UE in the third configuration in the first embodiment, the preset information of the PDCCH of the scheduling UE is used to indicate the narrowband where the resource allocated to the UE is located, and the specific one of the narrowband is allocated. The resource is notified in the resource allocation field of the DCI.
第五实施例Fifth embodiment
eNB分配给UE的资源与第一实施例到第三实施例类似，不同的是配置表示分配给UE的资源的信息的方法。表示分配给UE的资源的信息完全采用调度UE的PDCCH的预设信息表示，比如聚合等级或者重复次数或者控制信道占用的资源或者传输模式等。The resources allocated by the eNB to the UE are similar to the first embodiment to the third embodiment, except that a method of configuring information indicating resources allocated to the UE is configured. The information indicating the resources allocated to the UE is completely represented by preset information of the PDCCH scheduling the UE, such as the aggregation level or the number of repetitions or the resource or transmission mode occupied by the control channel.
比如UE接收PDSCH的窄带与调度UE接收PDSCH的PDCCH的窄带之间有一个预设的对应关系，比如假设PDCCH占用某一个窄带#5，那么PDSCH占用的窄带即为(PDCCH所在窄带+2)mod窄带总数，其中，“mod”为取模运算，假设窄带总数为16，则PDSCH所在窄带即为窄带#7，UE具体占所述窄带中的哪个资源，可以通过PDCCH的聚合等级来对应，比如表2所示。这样，eNB通过调度UE的PDCCH的预设信息表示的方式就可以通知分配给UE的资源，而不用在DCI中包含资源分配的信息。For example, the narrowband of the PDCCH that the UE receives the PDSCH has a preset correspondence with the narrowband of the PDCCH that the UE is scheduled to receive the PDSCH. For example, if the PDCCH occupies a certain narrowband #5, the narrowband occupied by the PDSCH is (the narrowband of the PDCCH is +2) mod. The total number of narrowband bands, where "mod" is a modulo operation, and assuming that the total number of narrowband bands is 16, the narrowband of the PDSCH is narrowband #7, and the UE specifically occupies which resource in the narrowband, and can correspond to the aggregation level of the PDCCH, for example, Table 2 shows. In this way, the eNB can notify the resources allocated to the UE by scheduling the preset information of the PDCCH of the UE, without including the information of the resource allocation in the DCI.
