- the embodiment of the invention provides a resource allocation method and device for realizing allocation of uplink shared channel resources in the case where a frequency hopping user device and a non-frequency hopping user device coexist.
- the LTE system uses Single Carrier-Frequency Division Multiple Access (SC-FDMA) technology, and the uplink resource allocation requires resources allocated to one user equipment, which must be in one time slot. It is continuous in the frequency domain and can be frequency hopped between two slots of one subframe. Since the frequency hopping transmission is mainly applicable to high-speed mobile user equipment or small-bandwidth services, when allocating resources to various user equipments and services in the system, it is often the case that some user equipments use frequency hopping transmission, and another part of user equipments use non-hopping. The case of frequency transmission.
- SC-FDMA Single Carrier-Frequency Division Multiple Access
- the process of performing the scheduling by the base station scheduler is to first determine the priority of the scheduling user equipment, and then complete the resource allocation for each user equipment according to the priority order of the user equipment, and when performing resource allocation on the user equipment,
- the system resource allocation status, the current user equipment frequency hopping, the frequency hopping mode currently used by the system, the frequency hopping type of the user equipment, and other factors find the available resources of the current user equipment, and then select the appropriate resource to allocate to the User equipment.
- the frequency hopping user equipment and the non-frequency hopping user equipment will use different resource mapping modes between the two slots in one subframe, and therefore, in frequency hopping If the user equipment and the non-frequency hopping user equipment coexist, if the uplink shared channel resources are not planned in advance, it is likely that the remaining resources cannot be allocated after the resource allocation of some user equipments is completed. Reduce system resource utilization and affect users at the same time
- the embodiment of the present invention provides an uplink shared resource allocation scheme in which a frequency hopping user equipment and a non-frequency hopping user equipment coexist, according to the demand of the frequency hopping user equipment and the non-frequency hopping user equipment for the number of PRB resources, combined with the hopping
- the frequency rule divides the uplink shared channel resource into two parts: a frequency hopping resource and a non-hopping resource.
- the frequency hopping user equipment preferentially allocates the frequency hopping resource
- the non-frequency hopping user equipment preferentially allocates the non hopping resource. . Therefore, the probability of occurrence of system resource fragments can be greatly reduced, the utilization rate of system spectrum resources can be improved, and the QoS of users can be more effectively ensured.
- the PUSCH resource allocation in the embodiment of the present invention refers to dividing the PUSCH resource into two parts: a frequency hopping resource and a non-hopping resource.
- the uplink shared resource allocation scheme in the case where the frequency hopping user equipment and the non-frequency hopping user equipment coexist in the embodiment of the present invention are applicable to the intraframe interframe hopping mode.
- a resource allocation method provided by an embodiment of the present invention includes:
- the PUSCH resource is allocated to the user equipment according to the frequency hopping resource and the non-hopping resource that are obtained by dividing the PUSCH resource in advance, where the frequency hopping user equipment preferentially allocates the frequency hopping resource, and the non hopping frequency user equipment preferentially allocates the non hopping resource.
- Frequency hopping resources are allocated to the user equipment according to the frequency hopping resource and the non-hopping resource that are obtained by dividing the PUSCH resource in advance, where the frequency hopping user equipment preferentially allocates the frequency hopping resource, and the non hopping frequency user equipment preferentially allocates the non hopping resource.
- the PUSCH resource is divided into semi-static configurations.
- the time granularity at which the base station performs dynamic resource allocation is 1 Transmission Time Interval (TTI), that is, lms.
- TTI Transmission Time Interval
- the PUSCH resource allocation has a large execution period relative to the PUSCH resource allocation (that is, the PUSCH resource is allocated to the user equipment), mainly for the following two reasons: Cause one: The ratio of the non-hopping resource to the frequency hopping resource is mainly based on frequency hopping. The ratio of the demand for the number of PRB resources by the user equipment and the non-frequency hopping user equipment is determined.
- frequency hopping depends mainly on the moving speed of the user equipment. Degrees and services used by user equipment, generally for high-speed user equipment, small bandwidth services use frequency hopping transmission. If each TTI performs resource division, it is necessary to separately estimate the requirement of the number of PRB resources of the frequency hopping user equipment and the non-frequency hopping user equipment that the current TTI participates in scheduling, thereby determining the ratio of the non-hopping resource to the frequency hopping resource. Then, the PUSCH resource division is performed.
- PUSCH resource partitioning can also reduce the amount of computation of the device.
- the LTE uplink uses synchronous HARQ.
- non-adaptive HARQ is mainly used.
- the non-adaptive HARQ means that the PRB resource used by the user equipment to retransmit data is determined according to the PDCCH indication received by the user equipment last time. Therefore, for the retransmission data, the occupied PRB resources are related to the resource location occupied by the previous transmission of the data. If each ⁇ is subjected to PUSCH resource division, the hopping user equipment cannot be retransmitted using the non-adaptive HARQ mode.
- the PRB resources occupied by the retransmission data are located in the range of the hopping resources, and the PRB resources occupied by the retransmission data that the non-frequency hopping user equipment uses the non-adaptive HARQ mode to retransmit are located in the non-hopping resource range, so that the PUSCH resource division is lost.
- the meaning is located in the range of the hopping resources, and the PRB resources occupied by the retransmission data that the non-frequency hopping user equipment uses the non-adaptive HARQ mode to retransmit are located in the non-hopping resource range, so that the PUSCH resource division is lost.
- the PUSCH resource partitioning in the embodiment of the present invention can be triggered in the following manner:
- the number of PRBs of the frequency user equipment and the number of PRBs actually allocated to the non-frequency hopping user equipment are used to determine the resources that are actually allocated to the frequency hopping user equipment and allocated to the non-frequency hopping users from the last time the PUSCH resource partitioning timer is started up to the current time.
- the ratio of resources of the device is used to determine the resources that are actually allocated to the frequency hopping user equipment and allocated to the non-frequency hopping users from the last time the PUSCH resource partitioning timer is started up to the current time. The ratio of resources of the device.
- the PUSCH resource partitioning timer expires and the PUSCH resource partitioning timer is last started to the current, the ratio of the resources actually allocated to the frequency hopping user equipment to the resources allocated to the non-frequency hopping user equipment, and the most recent division of the PUSCH resources
- the PUSCH resource is triggered. Re-division of the source.
- the condition for triggering the division of the PUSCH resource into the hopping resource and the non-hopping resource is: the preset PUSCH resource division timer expires; and,
- the duration of the PUSCH resource division timer is greater than one transmission time interval TTI.
- the specific duration can be configured according to actual needs. The longer the duration, the easier it is to achieve, but the lower the accuracy of resource allocation. The shorter the duration, the more complex the implementation, but the higher the accuracy of resource allocation.
- the specific preset range can also be configured according to actual needs.
- the ratio of the non-hopping resource to the frequency hopping resource is allocated to the non-frequency hopping user equipment according to the actual allocation to the frequency hopping user equipment in the interval between the two adjacent PUSCH resources.
- the proportion of resources is determined. That is to say, the ratio of the non-hopping resource and the frequency hopping resource is determined according to the requirement of the frequency hopping user equipment and the non-frequency hopping user equipment for the number of PRB resources.
- the time interval between the two adjacent PUSCH resource allocations is 7, and the number of PRBs actually allocated to the non-frequency hopping user equipment in the time interval 7 is NP : and the number of PRB resources actually allocated to the frequency hopping user equipment, Hd,
- the ratio of non-hopping resources to frequency hopping resources is
- the PUSCH resource division is performed at the time of T1, and the statistics of the amount of resources (the number of PRBs) actually allocated to the frequency hopping user equipment and the non-frequency hopping user equipment are respectively counted, and at time T2, the frequency hopping user equipment is actually allocated separately.
- the amount of resources is N : h . ⁇
- the actual amount of resources allocated to non-frequency hopping user equipment is And satisfying the triggering condition of the PUSCH resource division, then the PUSCH resource division is started again at the time T2, and the ratio of the divided non-hopping resources to the frequency hopping resources is 7; N h P ' L
- the principle of PUSCH resource division is to ensure that the resources used by the frequency hopping user equipment using frequency hopping resources are still within the frequency hopping resources.
- the main purpose of the PUBR resource is to avoid resource fragmentation. Therefore, the method for dividing the PUSCH resources needs to be determined according to the frequency hopping rule. Since the Typel hopping type and the Type2 hopping type follow different hopping rules, it is difficult to simultaneously consider the two hopping types when performing resource division. Therefore, PUSCH resource partitioning is only for one of the frequency hopping types. For different frequency hopping types, different PUSCH resource partitioning methods are used.
- the following describes the PUSCH resource partitioning for two types of hopping.
- the PUSCH resources for Typel frequency hopping are divided as follows:
- the Type 1 frequency hopping is frequency hopping according to the interval indicated in the PDCCH
- the PUSCH resources can be divided according to the hopping interval. It can be seen from Table 1 that in the case where the system bandwidth is less than 10 MHz, there is one frequency hopping interval value: V NP CH /2 ”; for 10 MHz or more (including 10 MHz)

- the frequency hopping resource region is composed of four consecutive PRB resources, the first PRB of the PUSCH resource, the l+ ⁇ /4 " PRB, the 1+2 NRB SCH /4, respectively.

- the PUSCH resources for Type 2 frequency hopping are divided as follows:
- Type2 frequency hopping uses a predefined frequency hopping method, which is a combination of subband hopping and mirroring.
- the subband hopping frequency shifts the PRB resources used by the user equipment from one subband to another to obtain frequency diversity.
- the user equipment occupies Resources may need to be mirrored within subbands.
- the same number of consecutive PRB resources can be divided into frequency hopping resources on both sides in each subband, and the central part of the PRB resources are used as non-hopping resources.
- the number of non-hopping resources and frequency hopping resources in each subband is determined according to the number of PRBs included in each subband and the proportion of non-hopping resources and frequency hopping resources.
- the number of PRBs that are divided into hopping resources on each side of each subband is:
- the number of PRBs in each subband as non-hopping resources is:

技术领域
本发明涉及通信技术领域, 尤其涉及一种资源分配方法及装置。 背景技术
为了提高资源利用率和系统吞吐量, 满足各种业务的业务服务质量 ( QoS , Quality of Service )需求, 长期演进(LTE, Long Term Evolution ) 系 统使用共享信道机制, 通过动态资源分配的方式实现系统内各个用户、 各个 业务的资源共享。
LTE系统可支持的最大系统带宽为 20MHz, 为了更好地支持宽带系统, LTE系统物理上行共享信道(PUSCH, Physical Uplink Shared Channel )釆用 单载波频分多址 ( SC-FDMA, Single Carrier - Frequency Division Multiple Access ), 在频域把整个宽带频率选择性信道分成多个平坦的子信道, 各子信 道之间相互正交。 在多用户业务共存的情况下, 可以灵活地分配时频资源进 行数据传输。
在 LTE系统中,可分配的最小物理资源单位为物理资源块( PRB, Physical Resource Block ),一个时隙中频域上连续的宽度为 180kHz的物理资源称为一 个 PRB。为了支持上行传输的单载波特性, PUSCH资源釆用连续分配的方式, 即要求分配给一个用户设备(UE, User Equipment )连续的 PRB资源。
PUSCH支持跳频传输, 即对于同一个数据块的传输, 用户设备占用的频 率资源从一个频段跳至另一个频段。 标准中定义了帧间跳频和帧内帧间跳频 两种跳频模式。 跳频模式为系统级配置。 如果系统配置为帧间跳频模式, 则
对于跳频用户设备, 其同一个混合自动重传请求 (HARQ, Hybrid Automatic Repeat Request )进程的数据传输在不同的子帧使用不同的 PRB资源; 如果系 统配置为帧内帧间跳频模式, 则对于跳频用户设备, 其在一个子帧内的两个 时隙占用不同的 PRB资源进行数据传输。 基站在完成对用户设备的 PUSCH 资源分配后, 通过物理下行控制信道 ( PDCCH, Physical Downlink Control Channel ) 的时隙 (Format ) 0向用户设备指示为其分配的第一个时隙的 PRB 资源位置以及跳频相关信息 (包括是否跳频, 使用的跳频类型等)。
此外, 标准中针对 PUSCH定义了两种类型的跳频: 类型 (Type ) 1跳频 和 Type 2跳频。在 PDCCH Format 0中定义了 1 ~ 2比特( bit )的跳频( hopping ) bit, 用于指示 UE使用的跳频类型, hopping bit的取值及其含义如表 1所示。
表 1 其中, 表示上行系统带宽; 表示 PDCCH中指示的用户设备在 子帧 i的第一个时隙使用的 PRB编号, 表示该用户设备跳频后使用的
PRB编号, NM 表示 PUSCH资源包含的 PRB数目。
以 20MHz系统带宽 ( 110个 PRB )为例, 如果 hopping bit指示为 00、
01或者 10, 表明用户设备使用 Typel跳频类型, 即按照 PDCCH中指示的跳
I I
频间隔进行跳频, 对于以上 3 个取值, 对应的跳频间隔分别为 L 」、
-
使用 Type2 跳频类型, Type2跳频是一种预定义的跳频方式, 跳频后的 PRB资源位置通
过预定义的公式计算得到, 其主要取决于用户设备上一次接收到的 PDCCH 中的 PRB资源分配指示、本次传输的子帧序号 /时隙序号、无线帧序号以及小 区 ID、 子带个数等因素。 Type2跳频中用到的子带数目由高层配置。
但是, 目前没有针对跳频用户设备和非跳频用户设备共存情况的上行共 享资源规划方案, 因此, 很可能出现资源碎片, 从而无法保证系统资源的充 分利用以及用户设备的 QoS。 发明内容
本发明实施例提供了一种资源分配方法及装置, 用以实现在跳频用户设 备和非跳频用户设备共存的情况下的上行共享信道资源的分配。

本发明实施例提供了一种资源分配方法及装置, 用以实现在跳频用户设 备和非跳频用户设备共存的情况下的上行共享信道资源的分配。
为了降低峰均比, LTE系统上行釆用单载波频分多址(SC-FDMA, Single Carrier - Frequency Division Multiple Access )技术, 上行资源分配要求分配给 一个用户设备的资源, 在一个时隙内必须在频域保持连续, 一个子帧的两个 时隙间可以跳频。 由于跳频传输主要适用于高速移动的用户设备或者小带宽 业务, 在对系统内的各个用户设备、 各个业务进行资源分配时, 经常出现一 部分用户设备使用跳频传输, 另一部分用户设备使用非跳频传输的情况。 基 站调度器执行调度的过程, 通常是首先确定调度用户设备的优先级, 然后再 根据用户设备优先级顺序依次完成对各用户设备的资源分配, 而在对用户设 备进行资源分配时, 需要首先根据已完成的系统资源分配情况, 以及当前用 户设备是否跳频, 系统当前使用的跳频模式, 用户设备的跳频类型等因素找 到当前用户设备的可用资源, 然后, 从中挑选合适的资源分配给该用户设备。 如果系统当前使用的是帧内帧间跳频模式, 对于跳频用户设备和非跳频用户 设备在一个子帧内的两个时隙间将釆用不同的资源映射方式, 因此, 在跳频
用户设备和非跳频用户设备共存的情况下, 如果没有预先对上行共享信道资 源进行合理的规划, 很可能出现在完成对部分用户设备的资源分配后, 剩余 的资源无法分配的情况, 从而导致系统资源利用率的降低, 同时影响用户的
QoS性能。
因此, 本发明实施例提出一种跳频用户设备和非跳频用户设备共存情况 下的上行共享资源分配方案, 根据跳频用户设备和非跳频用户设备对于 PRB 资源数目的需求, 并结合跳频规则将上行共享信道资源划分为跳频资源和非 跳频资源两部分, 在实际进行资源分配时, 对于跳频用户设备优先分配跳频 资源, 对于非跳频用户设备优先分配非跳频资源。 从而, 能够大大降低系统 资源碎片出现的概率, 提高系统频谱资源利用率, 更有效地保证用户的 QoS。
为了便于描述, 本发明实施例中的 PUSCH资源划分, 是指将 PUSCH资 源划分为跳频资源和非跳频资源两部分。
本发明实施例提出的在跳频用户设备和非跳频用户设备共存情况下的上 行共享资源分配方案, 适用于帧内帧间跳频模式。
下面结合附图对本发明实施例提供的技术方案进行说明。
参见图 1 , 本发明实施例提供的一种资源分配方法包括:
5101、 确定预先对 PUSCH资源进行划分得到的跳频资源和非跳频资源。
5102、 根据预先对 PUSCH资源进行划分得到的跳频资源和非跳频资源, 将 PUSCH 资源分配给用户设备, 其中, 对于跳频用户设备优先分配跳频资 源, 对于非跳频用户设备优先分配非跳频资源。
本发明实施例中, 对 PUSCH 资源的划分釆用半静态配置。 具体地, 基 站执行动态资源分配的时间粒度为 1个传输时间间隔( TTI, Transmission Time Interval ), 即 lms。 PUSCH资源划分相对于 PUSCH资源分配(即将 PUSCH 资源分配给用户设备)具有较大的执行周期, 主要出于以下两方面原因: 原因一: 非跳频资源与跳频资源的比例, 主要根据跳频用户设备和非跳 频用户设备对 PRB资源数目的需求比例来确定。
基于目前的跳频决策思想, 是否使用跳频主要取决于用户设备的移动速
度以及用户设备使用的业务, 一般对于高速用户设备, 小带宽业务使用跳频 传输。 如果每个 TTI都进行资源进行划分, 需要先分别估算当前 TTI参与调 度的跳频用户设备和非跳频用户设备对 PRB资源数目的需求, 以此确定非跳 频资源与跳频资源的比例, 再来进行 PUSCH 资源划分。 而在实际系统中, 可以认为跳频用户设备和非跳频用户设备对 PRB资源的需求是一个相对慢变 的过程, 因此没有必要频繁地进行 PUSCH 资源划分, 更重要的是, 不频繁 地进行 PUSCH资源划分还可以减少设备的计算量。
原因二: LTE 上行釆用同步 HARQ, 为了节省信令开销, 以非自适应 HARQ为主。 所谓非自适应 HARQ, 是指用户设备重传数据使用的 PRB资源 根据该用户设备上一次接收到的 PDCCH指示来确定。 因此, 对于重传数据, 其占用的 PRB资源与上一次传输该数据占用的资源位置有关, 如果每个 ΤΉ 都进行 PUSCH资源划分, 无法保证跳频用户设备使用非自适应 HARQ方式 进行重传的重传数据占用的 PRB资源位于跳频资源范围内, 非跳频用户设备 使用非自适应 HARQ方式进行重传的重传数据占用的 PRB资源位于非跳频 资源范围内, 这样 PUSCH资源划分就失去了意义。
因此, 基于以上原因, 本发明实施例中的 PUSCH 资源划分可釆用以下 方式进行触发:
预先定义一个 PUSCH资源划分定时器,用于控制相邻两次 PUSCH资源 划分的最小时间间隔, 在每次完成 PUSCH 资源划分的时刻重启该定时器, 同时从该时刻开始, 累计统计实际分配给跳频用户设备的 PRB数目和实际分 配给非跳频用户设备的 PRB数目, 用以确定从 PUSCH资源划分定时器最近 一次启动到当前, 实际分配给跳频用户设备的资源与分配给非跳频用户设备 的资源的比例。
当 PUSCH资源划分定时器超时,并且从 PUSCH资源划分定时器最近一 次启动到当前, 实际分配给跳频用户设备的资源与分配给非跳频用户设备的 资源的比例, 和最近一次对 PUSCH 资源划分得到的非跳频资源与跳频资源 的比例相比, 差值超过预设范围 (即存在较大差异) 时, 触发对 PUSCH 资
源的重新划分。
也就是说, 触发将 PUSCH资源划分为跳频资源和非跳频资源的条件为: 预先设置的 PUSCH资源划分定时器超时; 并且,
最近一次实际分配给跳频用户设备的资源与分配给跳频用户设备的资源 的比例, 和最近一次对 PUSCH 资源划分得到的非跳频资源与跳频资源的比 例相比, 差值超过预设范围。
其中, PUSCH资源划分定时器的时长大于一个传输时间间隔 TTI。 具体 的时长, 可以根据实际需要进行配置, 时长越长, 则越容易实现, 但资源分 配的精确度越低; 时长越短, 则实现越复杂, 但资源分配的精确度越高。
具体的预设范围, 也可以根据实际需要进行配置, 设置的范围越大, 则 PUSCH资源划分的执行周期越大, 同理, 就越容易实现, 但资源分配的精确 度越低; 设置的范围越小, 则实现越复杂, 但资源分配的精确度越高。
本发明实施例中, 非跳频资源与跳频资源的比例, 是按照在相邻两次 PUSCH资源划分的间隔时间内, 实际分配给跳频用户设备的资源与实际分配 给非跳频用户设备的资源的比例确定的。 也就是说, 根据跳频用户设备和非 跳频用户设备对 PRB资源数目的需求确定非跳频资源和跳频资源的比例。
殳设相邻两次 PUSCH资源划分的时间间隔为 7 , 分别统计时间间隔 7内 实际分配给非跳频用户设备的 PRB数目 N P: 和实际分配给跳频用户设备 的 PRB 资源数目 H d , 则非跳频资源和跳频资源的比例为
具体地, 例如在 Tl时刻执行了 PUSCH资源划分, 并开始统计实际分别 分配给跳频用户设备和非跳频用户设备的资源量(PRB数目 ),到了 T2时刻, 实际分别分配给跳频用户设备的资源量为 N:h 。』 , 实际分别分配给非跳频 用户设备的资源量为
, 并且满足了 PUSCH 资源划分的触发条件, 则 T2时刻开始重新进行 PUSCH资源划分, 此时划分的非跳频资源与跳频资 源的比例为; 7 =
Nh P ' L
下面具体介绍一下本发明实施例是如何对 PUSCH资源进行划分的。
PUSCH资源划分的原则,是保证使用跳频资源的跳频用户设备在跳频后 所使用的资源仍然在跳频资源范围内, 其主要目的是为了尽量避免产生资源 碎片。 因此, PUSCH资源划分的方法需要依据跳频规则来确定, 由于 Typel 跳频类型和 Type2跳频类型遵循的跳频规律有所不同, 在进行资源划分时很 难同时兼顾到这两种跳频类型, 因此, PUSCH资源划分只针对其中一种跳频 类型。 对于不同的跳频类型, 釆用不同的 PUSCH资源划分方法。
下面分别介绍针对两种跳频类型的 PUSCH资源划分。
针对 Typel跳频的 PUSCH资源划分如下:
由于 Type 1跳频是按照 PDCCH中指示的间隔来跳频, 因此可以依据跳 频间隔来对 PUSCH资源进行划分。从表 1可以看出,在系统带宽小于 10MHz 的情况下,存在 1个跳频间隔值: VNP CH /2」;对于 10MHz以上(包括 10MHz )
, , I \τ PUSCH I I τ PUSCH ι r I , TPUSCH , 的系统带笕, 存在 2个跳频间隔值: NRB ^ ^\NRB 2Jo 其中, Ν 表 示 PUSCH资源包含的 PRB数目。
为了保证使用跳频资源的跳频用户设备在跳频后所使用的资源仍然在跳 频资源范围内,对于系统带宽小于 10MHz的情况, 可以划分出两段包含相同 PRB数目的连续 PRB资源作为跳频资源, 并且两段连续 PRB资源的间隔为 [NR P^SCH 对于 lOMHz以上系统带宽, 可以划分出四段包含相同 PRB数目 的连续 PRB资源作为跳频资源, 并且相邻两段用作跳频的连续 PRB资源的 间隔为 /4」。 非跳频资源和跳频资源的数目根据系统 PUSCH资源包含 的 PRB数目, 以及非跳频资源和跳频资源的比例 来确定。
以 10MHz系统带宽为例 , 由于跳频资源区域由四段连续的 PRB资源组 成, 可以分别以 PUSCH资源的第 1个 PRB, 第 l+ ^ ^ /4」个 PRB, 第 1+2 NRBSCH /4」个 PRB , % 1+3 χ
/4」个 PRB作为起始 PRB,预留 连续的 PRB资源作为跳频资源。
N
其中, ^ 的计算方法为: 4 · (1 + ;/)
综上, 针对 Typel类型的跳频, 本发明实施例提供的对 PUSCH资源进 行划分, 得到跳频资源和非跳频资源的步骤包括:
对于系统带宽小于 10MHz的 PUSCH资源, 确定跳频资源需要的两段包 含相同数目物理资源块 PRB 的连续 PRB 资源的间隔为 L^, /2」, 其中, N H表示 PUSCH资源包含的 PRB数目; 根据非跳频资源与跳频资源的比
I I ^ ^ 例、 间隔 / 2」, 以及 PUSCH资源包含的 PRB数目, 确定 PUSCH资源 中的跳频资源和非跳频资源。
对于系统带宽大于或等于 10MHz的 PUSCH资源, 确定跳频资源需要的 四段包含相同数目物理资源块 PRB的连续 PRB资源中, 每两段相邻的连续 PRB资源的间隔为 LN«TCff / 4」;根据非跳频资源与跳频资源的比例、每两段相 邻的连续 PRB资源的间隔 [ NP SCH / 4」, 以及 PUSCH资源包含的 PRB数目, 确定 PUSCH资源中的跳频资源和非跳频资源。
针对 Type2跳频的 PUSCH资源划分如下:
Type2 跳频釆用的是一种预定义的跳频方式, 是子带跳频和镜像映射的 结合。 子带跳频使用户设备使用的 PRB资源从一个子带搬移到另一个子带, 从而获得频率分集; 此外, 为了降低多个小区位于同一个子带内的用户设备 之间的干扰, 用户设备占用的资源可能需要在子带内作镜像映射。
因此, 对于 Type2跳频, 可以在每个子带内的两侧分别划分相同数目的 连续 PRB资源作为跳频资源, 而中心部分的 PRB资源作为非跳频资源。 其 中,每个子带中非跳频资源和跳频资源的数目根据每个子带包含的 PRB个数 以及非跳频资源和跳频资源的比例 来确定。
每个子带中每一侧划分出来作为跳频资源的 PRB数目为:
每个子带中作为非跳频资源的 PRB数目为:
丄 ―丄、 ―
其中, 表示每个子带中包含的 PRB数目。
例如,在系统带宽包含三个子带的情况下,针对 Type2跳频类型的 PUSCH 资源划分的效果如图 3所示。
综上, 针对 Type2类型的跳频, 本发明实施例提供的对 PUSCH资源进 行划分, 得到跳频资源和非跳频资源的步骤包括:
根据非跳频资源与跳频资源的比例, 以及每个子带中包含的物理资源块 PRB数目, 确定 PUSCH资源中的跳频资源和非跳频资源, 其中, 在 PUSCH 资源中的每个子带中, 都包括跳频资源和非跳频资源, 并且, 跳频资源位于 子带的两侧, 该子带两侧作为跳频资源的 PRB连续且数目相同。
完成 PUSCH 资源划分后, 在为用户设备分配资源的过程中, 对于跳频 用户设备优先分配跳频资源, 对于非跳频用户设备优先分配非跳频资源。 若 跳频资源用尽, 则也可以为跳频用户设备分配非跳频资源, 同理, 若非跳频 资源用尽, 则也可以为非跳频用户设备分配跳频资源。
对于跳频用户设备, 选择使用与资源划分策略一致的跳频类型, 即都选 择针对 Typel类型划分的 PUSCH资源, 或者都选择针对 Type2类型划分的 PUSCH资源。 这样可以进一步有效地降低资源碎片的概率。
基于同一发明构思, 本发明实施例中还提供了一种资源分配装置, 由于 该装置解决问题的原理与资源分配方法相似, 因此该装置的实施可以参见方 法的实施, 重复之处不再赘述。

较佳地, 划分单元 203确定的非跳频资源与跳频资源的比例, 是按照在 相邻两次 PUSCH 资源划分的间隔时间内, 实际分配给跳频用户设备的资源 与实际分配给非跳频用户设备的资源的比例确定的。
