- time-frequency resource In the Long Term Evolution (LTE) system, some of the wireless bands are used for signal transmission.
- the time and frequency occupied by the signal transmission of the LTE system is called time-frequency resource.
- time-frequency resources are time-divided into frames of different lengths such as a frame, a subframe, and an Orthogonal Frequency Division Multiplexing (OFDM) symbol, where one frame The duration is 10ms, one frame contains 10 subframes, and one subframe time is 1 ms.
- One subframe can be divided into two slots (slots), and each slot is divided into multiple OFDM symbols.

Description
一种信令资源的配置方法、 设备及系统 技术领域 本发明涉及通信技术领域, 尤其涉及一种信令资源的配置方 法、 设备及系统。 The present invention relates to the field of communications technologies, and in particular, to a method, device, and system for configuring signaling resources.
背景技术 Background technique
在长期演进型 LTE(Long Term Evolution)系统中, 信号的传输 会使用部分的无线频段。 LTE 系统的信号传输所占用的时间与频 率, 称为时频资源。 在 LTE 系统中, 将时频资源在时间上分为帧 ( Frame ) , 子帧 ( subframe ) , 正交频分复用 OFDM ( Orthogonal Frequency Division Multiplexing ) 符号等不同长度的单位, 其中, 一个帧的持续时间是 10ms , 一个帧包含 10个子帧, 一个子帧时间 上是 1 ms , —个子帧上可以分成两个时隙 ( slot ) , 每个时隙 slot 又分成多个 OFDM 符号。 这里在一个子帧的频域结构中, 将 LTE 占据的系统带宽,划分成了称为资源块 PRB pair( Physical Resource Block Pair ) 的单位。 例如, 若系统带宽为 10MHz , 则一个子帧在 频域上划分为 50个 PRB pair的单位,而每个 PRB又分成多个资源 单位 RE ( Resource Element )。 在 LTE 系统中, 时频资源上需要传输多种信道和参考信号, 其中一种控制信道以物理下行控制信道 PDCCH( Physical Downlink Control Channel ) 为例 , 参考信号以 小 区公共参考信号 CRS ( Cell-specific Reference Signal ) 为例进行说明。 In the Long Term Evolution (LTE) system, some of the wireless bands are used for signal transmission. The time and frequency occupied by the signal transmission of the LTE system is called time-frequency resource. In an LTE system, time-frequency resources are time-divided into frames of different lengths such as a frame, a subframe, and an Orthogonal Frequency Division Multiplexing (OFDM) symbol, where one frame The duration is 10ms, one frame contains 10 subframes, and one subframe time is 1 ms. One subframe can be divided into two slots (slots), and each slot is divided into multiple OFDM symbols. Here, in the frequency domain structure of one subframe, the system bandwidth occupied by LTE is divided into units called a resource block PRB pair (Physical Resource Block Pair). For example, if the system bandwidth is 10 MHz, one subframe is divided into 50 PRB pair units in the frequency domain, and each PRB is divided into multiple resource units RE (Resource Element). In the LTE system, multiple channels and reference signals need to be transmitted on the time-frequency resources. One of the control channels uses the physical downlink control channel PDCCH (Physical Downlink Control Channel) as an example, and the reference signal uses the cell common reference signal CRS (Cell-specific). Reference Signal) is an example.
在 LTE 系 统中传输的信道还包括一种增强型控制信道 EPDCCH ( Enhanced PDCCH ) , 与 PDCCH不同在于, PDCCH会使 用一个子帧的前 1〜4个 OFDM符号 ,而 EPDCCH会使用除了前 1〜4 个 OFDM符号之外的 OFDM符号, 并且 PDCCH是占满整个系统 带宽的, 而 EPDCCH只会使用若干个 PRB pair。 在 LTE系统中, 为了使用 EPDCCH , —个基站可以给 UE ( User Equipment ) 配置
1〜2个 EPDCCH set集合, 每个 EPDCCH set包括若干个 PRB pair。 这里基站会通知 UE每个 EPDCCH set 占据了哪几个 PRB pairs。 发给一个 UE 的下行控制信令 DCI ( Downlink Control Information )会在配置给这个 UE的 EPDCCH set中的某些 PRB pair 进行发送。 为了帮助 UE能够知道 EPDCCH都在哪些 RE上进行发 送, 基站会使用高层信令指示 UE每个 EPDCCH set的资源映射信 息, 包括: 本 set包涵的 PRB数量、 本 set PRB具体是哪几个、 本 set 中由于传输了 CRS 而无法使用的 RE 信息以及本 set 的起始 OFDM符号数。 在 UE得到每个 EPDCCH set的资源映射信息后, 对 EPDCCH进行正确的解调与接收。 在现有技术中对 EPDCCH 进行资源映射的时候, 资源映射方 式中 PDCCH与 CRS在每个子帧中都会出现。 而在现有技术: 下行 间断传输 Downlink DTX ( downlink discontinuous transmission ) 中 PDCCH与 CRS只在某些子帧固定出现 (例如每帧中的第 0,5号子 帧 ), 其余的 PDCCH与 CRS将在剩下的子帧中随机的出现。 若仅 仍然按照现有技术, 根据基站高层信令指示的当前子帧集合 set需 要避开的 CRS信息以及当前 set的起始 OFDM符号数对 EPDCCH 进行资源映射, 则在部分子帧上与实际的 EPDCCH 资源映射无法 匹配, 造成无法正确接收 EPDCCH的问题。 The channel transmitted in the LTE system further includes an enhanced control channel EPDCCH (Enhanced PDCCH), which is different from the PDCCH in that the PDCCH uses the first 1-4 OFDM symbols of one subframe, and the EPDCCH uses the first 1-4 symbols. OFDM symbols outside the OFDM symbol, and the PDCCH is occupied by the entire system bandwidth, and the EPDCCH uses only a few PRB pairs. In the LTE system, in order to use the EPDCCH, one base station can configure the UE (User Equipment) 1 to 2 EPDCCH set sets, each EPDCCH set includes several PRB pairs. Here, the base station will inform the UE which number of PRB pairs each EPDCCH set occupies. The Downlink Control Information (DCI) sent to a UE is sent in some PRB pairs in the EPDCCH set configured for this UE. In order to help the UE to know which REs the EPDCCH is transmitting, the base station uses the high layer signaling to indicate the resource mapping information of each EPDCCH set of the UE, including: the number of PRBs included in the set, and the specific number of the set PRBs, The RE information in set that cannot be used due to the transmission of CRS and the number of starting OFDM symbols of this set. After the UE obtains the resource mapping information of each EPDCCH set, the EPDCCH is correctly demodulated and received. When resource mapping is performed on the EPDCCH in the prior art, the PDCCH and the CRS appear in each subframe in the resource mapping manner. In the prior art, the PDCCH and the CRS are fixed only in certain subframes (for example, subframes 0 and 5 in each frame), and the remaining PDCCHs and CRSs will be in the Downlink DTX (downlink discontinuous transmission). Random occurrences in the remaining sub-frames. If only the CRS information that needs to be avoided and the number of starting OFDM symbols of the current set are mapped to the EPDCCH according to the current technology, the current subframe set indicated by the high layer signaling of the base station is mapped to the EPDCCH. The EPDCCH resource mapping cannot be matched, causing the problem that the EPDCCH cannot be correctly received.

具体实施方式 下面将结合本发明实施例中的附图,对本发明实施例中的技术 方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明
一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本 领域普通技术人员在没有作出创造性劳动前提下所获得的所有其 他实施例, 都属于本发明保护的范围。 本发明提供了一种信令资源的配置方法, 适用于长期演进型The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. Some embodiments, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. The invention provides a method for configuring signaling resources, which is suitable for long-term evolution
LTE ( Long Term Evolution ) 系统中, 该 LTE系统的信号传输所占 用的时间与频率, 称为时频资源, 其中时频资源上还会传输参考信 号 ( Reference signal ) , 参考信号的传输主要用于接收端解调, 信 道估计等目 的; 此外时频资源也会用于传输各种信道, 包括数据信 道与控制信道。其中,一种控制信道称为物理下行控制信道 PDCCH ( Physical Downlink Control Channel ) , 一种参考信号称为小区公 共参考信号 CRS ( Cell-specific Reference Signal )„ LTE系统中传 输的信道还包括一种增强型控制信道 ( EPDCCH , Enhanced PDCCH ) , 与上述的 PDCCH相比也是用来传输下行控制信令的。 但是 EPDCCH所使用的时频资源与 PDCCH不同。 PDCCH会使用 一个子帧的前 1 -4个 OFDM符号 ,而 EPDCCH会使用后面的 OFDM 符号。 PDCCH是占满整个系统带宽的, 而 EPDCCH仅会占用整个 系统带宽中的若干个资源块对 PRB pair ( Physical Resource Block Pair )。 现有技术假设 CRS 与 OFDM符号在每个子帧上都存在, 所以一旦 UE接收到了 EPDCCH set的资源映射信息, 就会在所有 的子帧上都按照这里的配置进行 EPDCCH 的资源映射。 而在下行 间断传输 Downlink DTX 中, 每个子帧的 CRS、 PDCCH 出现的情 况不相同。 若仅仍然按照现有技术, 根据基站高层信令指示的当前 子帧集合 set需要避开的 CRS信息以及当前 set的起始 OFDM符号 数对 EPDCCH进行资源映射, 则在部分子帧上与实际的 EPDCCH 资源映射无法匹配, 造成无法正确接收 EPDCCH 的问题。 因此本 发明实施例提供了一种信令资源的配置方法, 在基站侧, 参照图 1 所示, 具体包括以下步骤: In the LTE (Long Term Evolution) system, the time and frequency occupied by the signal transmission of the LTE system is called time-frequency resource, and the reference signal is also transmitted on the time-frequency resource, and the transmission of the reference signal is mainly used for Receiver demodulation, channel estimation, etc.; in addition, time-frequency resources are also used to transmit various channels, including data channels and control channels. A control channel is called a Physical Downlink Control Channel (PDCCH), and a reference signal is called a Cell-specific Reference Signal (CRS). The channel transmitted in the LTE system further includes an enhancement. The EPDCCH (Enhanced PDCCH) is also used to transmit downlink control signaling compared to the PDCCH described above. However, the time-frequency resource used by the EPDCCH is different from the PDCCH. The PDCCH uses the first 1-4 of one subframe. OFDM symbols, and EPDCCH will use the following OFDM symbols. The PDCCH is the entire system bandwidth, and the EPDCCH only occupies several PRB pairs (Physical Resource Block Pairs) in the entire system bandwidth. And the OFDM symbol exists in each subframe, so once the UE receives the resource mapping information of the EPDCCH set, the EPDCCH resource mapping is performed according to the configuration here in all the subframes, and in the downlink intermittent transmission Downlink DTX. , the CRS and PDCCH of each subframe are different. If only According to the prior art, according to the current subframe set set indicated by the high layer signaling of the base station, the CRS information to be avoided and the initial set OFDM symbol number of the current set are used to perform resource mapping on the EPDCCH, and then mapped to the actual EPDCCH resource in the partial subframe. The problem is that the EPDCCH cannot be correctly received. Therefore, the embodiment of the present invention provides a method for configuring a signaling resource. The base station side, as shown in FIG. 1 , specifically includes the following steps:
101、 基站生成增强型增强型物理下行控制信道 EPDCCH的资 源指示信息。 其中, 该 EPDCCH 的资源指示信息包含 PDCCH配置参数和 / 或 CRS 配置参数, 该 PDCCH配置参数用于指示 EPDCCH所占用
的资源单位的位置, 该 CRS配置参数用于指示 EPDCCH需要避开 的资源单位; 该 PDCCH配置参数包括 PDCCH所在的子帧信息以 及各子帧中 PDCCH的起始位置; 该 CRS配置参数包括 CRS所在 的子帧信息以及各子帧中 CRS所占用的资源单位信息。 这里基站对用户设备 UE ( User Equipment ) 按照不同的子帧 分别为 EPDCCH配置资源映射。 其中, 具体的按照不同的子帧分别为 EPDCCH 配置参数为: 针对每个子帧中 CRS与 PDCCH的配置信息为 EPDCCH配置资源 映射, 根据 CRS与 PDCCH的配置信息可避免 UE在接收 EPDCCH 时避免 占用 CRS 或 PDCCH 占用 的资源单位 RE ( Resource Element ) ,从而正确接收 EPDCCH。这里在一个子帧的频域结构中, 将 LTE 占据的系统带宽, 划分成了称为资源块 PRB pair ( Physical Resource Block Pair ) 的单位。 例如, 若系统带宽为 10MHz , 贝' J一 个子帧在频域上划分为 50个 PRB pair的单位,而每个 PRB又分成 多个资源单位 RE ( Resource Element )。 其中, PDCCH会使用一个 子帧的前 1〜4 个 OFDM符号, 而 EPDCCH 会使用除了前 1〜4 个 OFDM符号后的 OFDM符号,并且 PDCCH是占满整个系统带宽的, 而 EPDCCH只会使用若干个 PRB pair。 101. The base station generates resource indication information of the enhanced enhanced physical downlink control channel EPDCCH. The resource indication information of the EPDCCH includes a PDCCH configuration parameter and/or a CRS configuration parameter, where the PDCCH configuration parameter is used to indicate that the EPDCCH is occupied. The location of the resource unit, the CRS configuration parameter is used to indicate a resource unit that the EPDCCH needs to avoid; the PDCCH configuration parameter includes a subframe information in which the PDCCH is located, and a start position of the PDCCH in each subframe; the CRS configuration parameter includes a CRS Subframe information and resource unit information occupied by CRS in each subframe. Here, the base station configures a resource mapping for the EPDCCH for the user equipment UE (User Equipment) according to different subframes. Specifically, the EPDCCH configuration parameters are respectively configured according to different subframes: the configuration information of the CRS and the PDCCH in each subframe is a resource mapping of the EPDCCH, and the configuration information of the CRS and the PDCCH can prevent the UE from occupying the CRS when receiving the EPDCCH. Or the resource unit RE ( Resource Element ) occupied by the PDCCH, so that the EPDCCH is correctly received. Here, in the frequency domain structure of one subframe, the system bandwidth occupied by LTE is divided into units called a resource block (PB) (Physical Resource Block Pair). For example, if the system bandwidth is 10 MHz, one subframe of the cell is divided into units of 50 PRB pairs in the frequency domain, and each PRB is divided into multiple resource units RE (Resource Element). The PDCCH uses the first 1 to 4 OFDM symbols of one subframe, and the EPDCCH uses the OFDM symbols except the first 1 to 4 OFDM symbols, and the PDCCH is used to occupy the entire system bandwidth, and the EPDCCH only uses a number of OFDM symbols. PRB pair.
102、 基站向用户设备发送该 EPDCCH的资源指示信息, 指示 用户设备根据该 EPDCCH 的资源指示信息确定各子帧信令资源中 用于传输 EPDCCH所占用的资源单位。 本发明实施例提供的信令资源的配置方法, 基站通过根据不同 子帧中的 CRS以及 PDCCH的配置参数生成增强型增强型物理下行 控制信道 EPDCCH 的资源指示信息, 以便用户设备根据增强型增 强型物理下行控制信道 EPDCCH 的资源指示信息判断信令资源中 用于传输 EPDCCH所占用的资源单位 RE。 解决了由于无法准确的 对 EPDCCH进行资源映射, 从而无法正确传输的问题。 The base station sends the resource indication information of the EPDCCH to the user equipment, and the user equipment is instructed to determine, according to the resource indication information of the EPDCCH, the resource unit used for transmitting the EPDCCH in each subframe signaling resource. The method for configuring the signaling resource provided by the embodiment of the present invention, the base station generates the resource indication information of the enhanced enhanced physical downlink control channel EPDCCH according to the CRS and the configuration parameters of the PDCCH in different subframes, so that the user equipment is enhanced according to the enhancement type. The resource indication information of the physical downlink control channel EPDCCH determines the resource unit RE used for transmitting the EPDCCH in the signaling resource. The problem that the EPDCCH cannot be accurately mapped due to the inability to accurately transmit the EPDCCH is solved.
本发明实施例提供了一种信令资源的配置方法, 在用户设备侧, 参照图 2所示, 具体包括以下步骤:
201、 用户设备接收基站发送的物理下行控制信道 EPDCCH的 资源指示信息。 The embodiment of the present invention provides a method for configuring a signaling resource. The user equipment side, as shown in FIG. 2, specifically includes the following steps: 201. The user equipment receives resource indication information of a physical downlink control channel EPDCCH sent by the base station.
其中, 该 EPDCCH 的资源指示信息包含 PDCCH配置参数和 / 或 CRS 配置参数, 该 PDCCH配置参数用于指示 EPDCCH所占用 的资源单位的位置, 该 CRS配置参数用于指示 EPDCCH需要避开 的资源单位; 该 PDCCH配置参数包括 PDCCH所在的子帧信息以 及各子帧中 PDCCH的起始位置; 该 CRS配置参数包括 CRS所在 的子帧信息以及各子帧中 CRS所占用的资源单位信息。 The resource indication information of the EPDCCH includes a PDCCH configuration parameter and/or a CRS configuration parameter, where the PDCCH configuration parameter is used to indicate a location of a resource unit occupied by the EPDCCH, where the CRS configuration parameter is used to indicate a resource unit that the EPDCCH needs to avoid; The PDCCH configuration parameter includes subframe information in which the PDCCH is located and a start position of the PDCCH in each subframe. The CRS configuration parameter includes subframe information in which the CRS is located and resource unit information occupied by the CRS in each subframe.
202、 用户设备根据 EPDCCH的资源指示信息接收增强型物理 下行控制信道 EPDCCH。 这里用户设备根据 EPDCCH 的资源指示信息接收增强型物理 下行控制信道 EPDCCH , 其中, 具体如下所述: a、若 PDCCH对应的 EPDCCH的资源指示信息中指示 PDCCH 在第 0和第 5子帧中, 并且指示 PDCCH的起始符号数, 即 PDCCH 的起始的正交频分复用 OFDM ( Orthogonal Frequency Division Multiplexing ) 符号, 由于 PDCCH 在每个资源块对 PRB pair202. The user equipment receives the enhanced physical downlink control channel EPDCCH according to the resource indication information of the EPDCCH. The user equipment receives the enhanced physical downlink control channel EPDCCH according to the resource indication information of the EPDCCH, where the following is as follows: a. If the resource indication information of the EPDCCH corresponding to the PDCCH indicates that the PDCCH is in the 0th and 5th subframes, and Indicates the number of starting symbols of the PDCCH, that is, the Orthogonal Frequency Division Multiplexing (OFDM) symbol of the start of the PDCCH, since the PDCCH is in each resource block pair PRB pair
( Physical Resource Block Pair ) 中仅占据前 1 -3个 OFDM符号, 则用户设备接收到 EPDCCH的资源指示信息,将能够根据 EPDCCH 的资源指示信息获知在第 0 和第 5 子帧中, 因此在接收 EPDCCH 时, 用户设备将避免占用的 PDCCH所占据的 OFDM部分。 b、 若 CRS对应的 EPDCCH的资源指示信息中指示 CRS在第 0或第 5子帧中,并且已知 CRS的端口数,以及频域偏移 frequency shift , 则用户设备接收到 EPDCCH 的资源指示信息, 将能够根据 EPDCCH的资源指示信息获知在第 0和第 5子帧中, EPDCCH配置 资源映射不包括 CRS所占据的 RE部分。 本发明实施例提供的信令资源的配置方法, 基站通过根据不同 子帧中的 CRS以及 PDCCH的配置参数生成增强型增强型物理下行 控制信道 EPDCCH 的资源指示信息, 以便用户设备根据增强型增 强型物理下行控制信道 EPDCCH 的资源指示信息判断信令资源中 用于传输 EPDCCH所占用的资源单位 RE。 解决了由于无法准确的
对 EPDCCH进行资源映射, 从而无法正确传输的问题。 If the first 1-3 OFDM symbols are occupied in the (Physical Resource Block Pair), the user equipment receives the resource indication information of the EPDCCH, and is able to learn the information in the 0th and 5th subframes according to the resource indication information of the EPDCCH, and therefore receives the PDCCH. At EPDCCH, the user equipment will avoid the OFDM portion occupied by the occupied PDCCH. If the resource indication information of the EPDCCH corresponding to the CRS indicates that the CRS is in the 0th or 5th subframe, and the number of ports of the CRS is known, and the frequency domain offset frequency shift, the user equipment receives the resource indication information of the EPDCCH. According to the resource indication information of the EPDCCH, it can be learned that in the 0th and 5th subframes, the EPDCCH configuration resource mapping does not include the RE part occupied by the CRS.

The resource indication information of the physical downlink control channel EPDCCH determines the resource unit RE used for transmitting the EPDCCH in the signaling resource. Solved because it cannot be accurate The problem of resource mapping for the EPDCCH, so that it cannot be correctly transmitted.
具体的, 以下结合具体的实施例进行说明。 实施例一 可以在图 1或图 2所示的实施例的基础上, 参照图 3所示, 本发明 的实施例提供了一种信令资源的配置方法, 参照图 3所示, 为基站按照 不同子帧的配置情况分别为 EPDCCH配置资源映射的过程, 具体步骤如 下: Specifically, the following description will be made in conjunction with specific embodiments. The embodiment 1 can be based on the embodiment shown in FIG. 1 or FIG. 2, and the embodiment of the present invention provides a method for configuring signaling resources. Referring to FIG. 3, the base station is configured according to FIG. The configuration of different subframes is the process of configuring resource mapping for EPDCCH. The specific steps are as follows:
这里基站侧才艮据物理下行控制信道 PDCCH ( Physical Downlink Control Channel ) 以及小 区公共参考信号 CRS ( Cell-specific Reference Signal ) 配置对应 PDCCH的第一配置信息以及对应 CRS的 第二配置信息中, 包括两种方式, 具体如步骤 301和步骤 302、 步骤 303 以及步骤 304所述: Here, the base station side configures the first configuration information corresponding to the PDCCH and the second configuration information corresponding to the CRS according to the physical downlink control channel PDCCH (Physical Downlink Control Channel) and the cell common reference signal CRS (Cell-specific Reference Signal), including two The method is specifically as described in step 301 and step 302, step 303 and step 304:
301、基站根据各个子帧中 PDCCH的占用的 OFDM符号的起始 符号数生成 EPDCCH的资源指示信息。 其中, 该 EPDCCH 的资源指示信息包含 PDCCH配置参数和 / 或 CRS 配置参数, 该 PDCCH配置参数用于指示 EPDCCH所占用 的资源单位的位置, 该 CRS配置参数用于指示 EPDCCH需要避开 的资源单位; 该 PDCCH配置参数包括 PDCCH所在的子帧信息以 及各子帧中 PDCCH的起始位置; 该 CRS配置参数包括 CRS所在 的子帧信息以及各子帧中 CRS所占用的资源单位信息。 301. The base station generates resource indication information of the EPDCCH according to the starting symbol number of the OFDM symbol occupied by the PDCCH in each subframe. The resource indication information of the EPDCCH includes a PDCCH configuration parameter and/or a CRS configuration parameter, where the PDCCH configuration parameter is used to indicate a location of a resource unit occupied by the EPDCCH, where the CRS configuration parameter is used to indicate a resource unit that the EPDCCH needs to avoid; The PDCCH configuration parameter includes subframe information in which the PDCCH is located and a start position of the PDCCH in each subframe. The CRS configuration parameter includes subframe information in which the CRS is located and resource unit information occupied by the CRS in each subframe.
这里 EPDCCH 的 资源指示信息用 于指示用 户 设备在对 EPDCCH进行接收时避开 PDCCH所占用的资源, 其中基站在分配 每个资源块 PRB pair中占用的 OFDM时, PDCCH仅占用一个子帧 中前 1 -3 个 OFDM符号。 其中, 根据 PDCCH生成的 EPDCCH的 资源指示信息可以为, 以一个帧的长度为例, 在子帧集合 1 中, 即 第 0子帧和第 5子帧中, PDCCH的起始符号数 OFDM 1 ; 在子帧集 合 2 中, 即除第 0子帧和第 5子帧外的其他子帧 (如第 1子帧〜第 4子帧以及第 6子帧〜第 9子帧 )中, PDCCH的起始符号数 OFDM2。 以便于用户设备在 EPDCCH的资源指示信息对 EPDCCH进行接收
时, 避免接收该第一配置信息中的 PDCCH所占用的 OFDM符号。 Here, the resource indication information of the EPDCCH is used to indicate that the user equipment avoids resources occupied by the PDCCH when receiving the EPDCCH, where the PDCCH occupies only the first one of the subframes when allocating the OFDM occupied by each resource block PRB pair - 3 OFDM symbols. The resource indication information of the EPDCCH generated according to the PDCCH may be, for example, the length of one frame. In the subframe set 1, that is, in the 0th subframe and the 5th subframe, the starting symbol number of the PDCCH is OFDM 1 ; In the subframe set 2, that is, in other subframes except the 0th subframe and the 5th subframe (such as the 1st subframe to the 4th subframe and the 6th subframe to the 9th subframe), the PDCCH starts The starting symbol number is OFDM2.

In addition, when the user equipment receives the EDPCCH according to the resource indication information of the EPDCCH, the resource occupied by the CRS in the resource indication information of the EPDCCH is avoided. Or,

When the CRS is included only in the first subframe set, the resource indication information of the EPDCCH includes a port number of the CRS, a frequency domain offset position, and/or a first subframe set in which the CRS exists. It is assumed here that the CRS exists only in the first subframe set, specifically taking the length of one frame as an example. It is assumed that CRS exists in the 0th subframe and the 5th subframe, and the other is not included in the 0th subframe and the 5th subframe.

Specifically, the user equipment configures resource mapping for the enhanced physical downlink control channel EPDCCH according to the resource indication information of the EPDCCH, and the specific steps are as follows:
a、 当接收的 EPDCCH的资源指示信息中 PDCCH仅存在第一 子帧集时, 根据 EPDCCH的资源指示信息接收 EPDCCH。 a. When the PDCCH has only the first subframe set in the resource indication information of the received EPDCCH, the EPDCCH is received according to the resource indication information of the EPDCCH.
其中,该 EPDCCH的资源指示信息中 PDCCH 占用的第一子帧 集中的子帧数, 和 PDCCH 占用的 OFDM符号的起始符号数。 这里假设规定在第 0子帧与第 5子帧中存在 PDCCH , 其他除 过第 0子帧与第 5子帧中没有 PDCCH , 则根据 PDCCH所在的子 帧 (如 PDCCH位于第 0子帧与第 5子帧 )、 PDCCH在一个子帧中 的 PRB pair中占用的起始符号数 OFDM , 为 EPDCCH配置资源映 射, 由于已知 PDCCH的起始符号数 OFDM , 则根据现有规定, 在 同一子帧的 PDCCH 占用的 OFDM后面为 EPDCCH配置需要占用
的 OFDM。 b、 当接收的 EPDCCH 的资源指示信息中 CRS 仅存在第一子 帧集时, 根据 EPDCCH的资源指示信息接收 EPDCCH。 其中, EPDCCH 的资源指示信息中 CRS 占用的子帧为第一子 帧集中的子帧, 以及 CRS 占用的端口数和 /或频域偏移位置。 这里假设规定在第 0 子帧与第 5 子帧中存在 CRS , 其他除过 第 0子帧与第 5子帧中没有 CRS ,则根据 CRS所在的子帧(如 CRS 位于第 0子帧与第 5子帧)、 CRS在一个子帧中的端口数以及 CRS 在一个子帧中的频域偏移 frequency shift , 为 EPDCCH配置资源映 射, 由于已知 CRS 所在的子帧、 CRS在一个子帧中的端口数以及 CRS在一个子帧中的频域偏移 frequency shift , 则根据现有规定, 在同一子帧的 PDCCH占用的 OFDM后面以及除 CRS占用的 OFDM 部分为 EPDCCH配置需要占用的 OFDM。 本发明实施例提供的信令资源的配置方法, 基站通过根据不同 子帧中的 CRS以及 PDCCH的配置参数生成增强型增强型物理下行 控制信道 EPDCCH 的资源指示信息, 以便用户设备根据增强型增 强型物理下行控制信道 EPDCCH 的资源指示信息判断信令资源中 用于传输 EPDCCH所占用的资源单位 RE。 解决了由于无法准确的 对 EPDCCH进行资源映射, 从而无法正确传输的问题。 可选的, 当基站在为多个 EPDCCH 配置资源映射时, 具体步 骤如下所述: al、 当基站为多个 EPDCCH set集合配置资源映射时, 若至少 一个子帧中确定包含 CRS 以及 PDCCH , 则将至少一个子帧设置在 子帧信息中。 The number of subframes in the first subframe set occupied by the PDCCH in the resource indication information of the EPDCCH, and the number of start symbols of the OFDM symbol occupied by the PDCCH. It is assumed here that the PDCCH is present in the 0th subframe and the 5th subframe, and the other subframes are not included in the 0th subframe and the 5th subframe, and the subframe is located according to the PDCCH (eg, the PDCCH is located in the 0th subframe and the PDCCH) 5 subframes), the number of starting symbols occupied by the PDCCH in the PRB pair in one subframe, and the resource mapping is configured for the EPDCCH. Since the number of starting symbols of the PDCCH is known to be OFDM, the same subframe is used according to the existing regulations. The PDCCH occupied by the PDCCH is followed by the EPDCCH configuration. OFDM. b. When the CRS of the received EPDCCH has only the first subframe set in the CRS, the EPDCCH is received according to the resource indication information of the EPDCCH. The subframes occupied by the CRS in the resource indication information of the EPDCCH are the subframes in the first subframe set, and the number of ports and/or frequency domain offset positions occupied by the CRS. It is assumed here that there is a CRS in the 0th subframe and the 5th subframe, and other subframes in which the CRS is not included in the 0th subframe and the 5th subframe (for example, the CRS is located in the 0th subframe and the 5 subframes), the number of ports of the CRS in one subframe and the frequency shift of the CRS in one subframe, the frequency shift is configured for the EPDCCH, since the subframe in which the CRS is located and the CRS are in one subframe The number of ports and the frequency shift of the CRS in one subframe are frequency shift. According to the existing regulations, the OFDM occupied by the PDCCH of the same subframe and the OFDM part occupied by the CRS are OFDM required to be occupied by the EPDCCH configuration. The method for configuring the signaling resource provided by the embodiment of the present invention, the base station generates the resource indication information of the enhanced enhanced physical downlink control channel EPDCCH according to the CRS and the configuration parameters of the PDCCH in different subframes, so that the user equipment is enhanced according to the enhancement type. The resource indication information of the physical downlink control channel EPDCCH determines the resource unit RE used for transmitting the EPDCCH in the signaling resource. The problem that the EPDCCH cannot be accurately mapped due to the inability to accurately transmit the EPDCCH is solved. Optionally, when the base station is configured to perform resource mapping for multiple EPDCCHs, the specific steps are as follows: al. When the base station configures resource mapping for multiple EPDCCH set sets, if at least one subframe is determined to include the CRS and the PDCCH, At least one subframe is set in the subframe information.
这里以一个帧的长度为例进行举例说明 , 当基站为多 个 EPDCCH set配置资源映射时, ^_设基站确定在第 0子帧和第 5子 帧上存在 CRS 以及 PDCCH , 则配置第 0 EPDCCH set集合和第 1 EPDCCH set集合中的第 0子帧和第 5子帧中均配置存在 CRS以及 PDCCH。 故当用户设备接收到根据确定在第 0 子帧和第 5 子帧上 存在 CRS 以及 PDCCH , 生成的对应 PDCCH以及 CRS的 EPDCCH
的资源指示信息时,将根据 EPDCCH的资源指示信息配置 EPDCCH 的资源映射。 The length of one frame is taken as an example. When the base station configures resource mapping for multiple EPDCCH sets, the base station determines that there are CRS and PDCCH in the 0th subframe and the 5th subframe, and then configures the 0th EPDCCH. The CRS and the PDCCH are configured in both the 0th subframe and the 5th subframe in the set set and the 1st EPDCCH set set. Therefore, when the user equipment receives the EPDCCH corresponding to the PDCCH and the CRS generated according to the determination of the presence of the CRS and the PDCCH on the 0th subframe and the 5th subframe, When the resource indication information is used, the resource mapping of the EPDCCH is configured according to the resource indication information of the EPDCCH.
a2、 当基站为多个 EPDCCH set集合配置资源映射时, 若至少 一个子帧中确定包含 CRS 以及 PDCCH , 则用户设备根据 EPDCCH 的资源指示信息接收的各个 EPDCCH set集合上均包含 CRS 以及 PDCCH。 b l、 若至少一个子帧中确定不包含 CRS 以及 PDCCH , 则将所 有子帧不设置在子帧信息中。 A2: When the base station configures the resource mapping for the multiple EPDCCH set sets, if the CRS and the PDCCH are determined to be included in the at least one subframe, the user equipment includes the CRS and the PDCCH according to the EPDCCH set received by the resource indication information of the EPDCCH. b l. If it is determined in at least one subframe that the CRS and the PDCCH are not included, all subframes are not set in the subframe information.
假设基站确定除第 0子帧和第 5子帧外的其他子帧上均不存在 CRS 以及 PDCCH , 则配置第 OEPDCCH set集合和第 l EPDCCH set 集合中的其他子帧均不存在 CRS 以及 PDCCH , 故当用户设备接收 到根据确定在除第 0子帧和第 5子帧外的其他子帧中均不存在 CRS 以及 PDCCH , 生成的对应 PDCCH 以及 CRS的 EPDCCH的资源指 示信息时, 将根据 EPDCCH的资源指示信息配置 EPDCCH的资源 映射。 Assuming that the base station determines that there is no CRS and PDCCH on all subframes except the 0th subframe and the 5th subframe, the CES and the PDCCH are not configured in the OEPDCCH set set and the other subframes in the 1st EPDCCH set set. Therefore, when the user equipment receives the resource indication information of the EPDCCH corresponding to the CPDCCH and the PDCCH generated in the other subframes except the 0th subframe and the 5th subframe, the EPDCCH is determined according to the EPDCCH. The resource indication information configures a resource mapping of the EPDCCH.
b2、 若至少一个子帧中确定不包含 CRS 以及 PDCCH , 则用户 设备根据 EPDCCH的资源指示信息接收的各个 EPDCCH set集合上 均没有 CRS 以及 PDCCH。 If the CRS and the PDCCH are not included in the at least one subframe, the user equipment does not have the CRS and the PDCCH on each EPDCCH set received according to the resource indication information of the EPDCCH.
c l、 若其他的子帧中无法确定是否包含 CRS 以及 PDCCH , 则 将至少一个其他的子帧设置在子帧信息中,且至少一个其他的子帧 不设置在子帧信息中。 这里假设基站除第 0子帧和第 5子帧外的其他子帧无法确定是 否存在 CRS 以及 PDCCH , 则假设在第 0 子帧集合中均存在 CRS 以及 PDCCH , 在第 1子帧集合中不存在。 c2、 若其他的子帧中无法确定是否包含 CRS 以及 PDCCH , 则 用户设备在接收的多个 EPDCCH set集合中,根据 EPDCCH的资源 指示信息接收的至少一个 EPDCCH set集合存在 CRS和 PDCCH , 以及接收的至少一个 EPDCCH set集合不存在 CRS和 PDCCH。 具体如表 1所示:
第 0子帧集合 第 1子帧集合 Cl. If it is not determined in the other subframe whether the CRS and the PDCCH are included, at least one other subframe is set in the subframe information, and at least one other subframe is not set in the subframe information. It is assumed here that the base station cannot determine whether there is a CRS or a PDCCH except for the subframes other than the 0th subframe and the 5th subframe, and it is assumed that the CRS and the PDCCH exist in the 0th subframe set, and the subframe does not exist in the first subframe set. . C2, if the CRS and the PDCCH are not determined in the other subframes, the user equipment, in the received multiple EPDCCH set sets, the CRS and the PDCCH according to the at least one EPDCCH set set received according to the resource indication information of the EPDCCH, and the received There is no CRS and PDCCH in at least one EPDCCH set set. The details are shown in Table 1: 0th subframe set 1st subframe set

Set 1 表 1 这里如表 1所示, 第一行第二列为第 0子帧和第 5子帧, 第一行第 三列为以一个帧的长度为例除第 0子帧和第 5子帧外的其他子帧,即第 1 子帧〜第 4子帧以及第 6子帧〜第 9子帧。 第二行第一列为第 OEPDCCH set集合,第三行第一列为第 1EPDCCH set集合, 其中, 根据第一行的第二列与第一行的第三列描述第 0子帧集 合与第 1子帧集合的状态, 如表 1所示: 在第 OEPDCCH set集合中第 0子帧和第 5子帧中存在 PDCCH和 CRS ,在除第 0子帧和第 5子帧外的其他子帧中也均存在 PDCCH和 CRS; 在第 1EPDCCH set集合中第 0子帧和第 5子帧中存在 PDCCH和 CRS ,在除第 0子帧和第 5子帧外的其他子帧中均不存在 PDCCH和 CRS。 Set 1 Table 1 Here, as shown in Table 1, the first row and the second column are the 0th subframe and the 5th subframe, and the first row and the third column are divided into the 0th subframe and the 5th by taking the length of one frame as an example. Other sub-frames, that is, the first to fourth sub-frames and the sixth to ninth sub-frames. The first row of the second row is the OEPDCCH set set, and the first row of the third row is the 1E EPDCCH set set, wherein the 0th subframe set and the third column are described according to the second column of the first row and the third column of the first row 1 state of the subframe set, as shown in Table 1: PDCCH and CRS exist in the 0th subframe and the 5th subframe in the OEPDCCH set set, and other subframes except the 0th subframe and the 5th subframe PDCCH and CRS are also present in the PDCCH and the CRS in the 0th subframe and the 5th subframe in the 1st EPDCCH set, and no PDCCH exists in other subframes except the 0th subframe and the 5th subframe. And CRS.
具体如下所述: 如表 1所示, 假设基站不确定除第 0子帧和第 5子 帧外是否还有别的子帧存在 PDCCH 和 CRS , 基站则设定至少第 OEPDCCH set集合中所有子帧均存在 PDCCH和 CRS ,设定第 1EPDCCH set集合中除第 0子帧和第 5子帧存在 PDCCH和 CRS外, 其他子帧中均 不存在 PDCCH和 CRS。 在除第 0子帧和第 5子帧外若基站决定在其他子帧中也传输 PDCCH 和 CRS , 则使用表 1所示的第 OEPDCCH set集合, 令第 OEPDCCH set 集合传输 PDCCH 和 CRS , 在用户设备侧, 则根据 0〜9 子帧上均传输 PDCCH和 CRS的情况避免在对 EPDCCH进行资源映射配置时占据 0〜9
子帧上 PDCCH和 CRS所占用的资源。 当基站确定在除第 0子帧和第 5子帧外的其他子帧中不存在 PDCCH 和 CRS时, 则使用表 1所示的第 1EPDCCH set集合, 令第 1EPDCCH set 集合中的第 0 子帧和第 5 子帧传输 PDCCH 和 CRS , 其他子帧中没有 PDCCH和 CRS, 在用户设备侧, 则根据 0〜9子帧上均不传输 PDCCH和 CRS的情况接收 EPDCCH, 进而能够令用户设备正确的接收 EPDCCH, 避免了占用子帧中 PDCCH和 CRS所占用的资源。 本发明实施例提供的信令资源的配置方法, 基站通过对多个 EPDCCH进行资源配置,当不确定除特定子帧外包括物理下行控制 信道 PDCCH 以及小区公共参考信号 CRS时,令至少一个 EPDCCH set集合全部包含物理下行控制信道 PDCCH以及小区公共参考信号 CRS , 以及至少一个子帧集合不包含物理下行控制信道 PDCCH 以 及小区公共参考信号 CRS。 解决了由于无法准确的对 EPDCCH 进 行资源映射, 从而无法正确接收的问题。 The details are as follows: As shown in Table 1, it is assumed that the base station determines whether there are other subframes other than the 0th subframe and the 5th subframe, and the PDCCH and the CRS exist, and the base station sets at least all the children in the OEPDCCH set set. The PDCCH and the CRS are present in the frame, and the PDCCH and the CRS are not present in the other subframes except for the PDCCH and the CRS in the 0th subframe and the 5th subframe in the 1st EPDCCH set. If the base station decides to transmit the PDCCH and the CRS in other subframes in addition to the 0th subframe and the 5th subframe, the OEPDCCH set set shown in Table 1 is used, and the OEPDCCH set is transmitted to transmit the PDCCH and the CRS in the user. On the device side, the PDCCH and the CRS are transmitted on the 0 to 9 subframes to avoid occupying 0 to 9 when performing resource mapping configuration on the EPDCCH. The resources occupied by the PDCCH and CRS on the subframe. When the base station determines that there is no PDCCH and CRS in other subframes except the 0th subframe and the 5th subframe, the 1st EPDCCH set set shown in Table 1 is used, and the 0th subframe in the 1st EPDCCH set set is used. The PDCCH and the CRS are transmitted in the 5th subframe, and the PDCCH and the CRS are not in the other subframes. On the user equipment side, the EPDCCH is received according to the case where the PDCCH and the CRS are not transmitted on the 0 to 9 subframes, thereby enabling the user equipment to be correct. Receiving the EPDCCH avoids occupying resources occupied by the PDCCH and the CRS in the subframe. The method for configuring a signaling resource provided by the embodiment of the present invention, the base station performs resource configuration on multiple EPDCCHs, and when it is determined that the physical downlink control channel PDCCH and the cell common reference signal CRS are included except for a specific subframe, at least one EPDCCH set is obtained. The set includes the physical downlink control channel PDCCH and the cell common reference signal CRS, and the at least one subframe set does not include the physical downlink control channel PDCCH and the cell common reference signal CRS. The problem that the EPDCCH cannot be accurately received due to the inability to accurately receive the resource is solved.
实施例二 可以在图 1、 图 2或图 3所示的实施例的基础上, 参照图 4所示, 本发明的实施例提供了一种信令资源的配置方法, 参照图 4所示, 为基 站按照不同子帧的配置情况在若个别子帧中的配置发生变化时分别为 EPDCCH配置资源映射的过程, 具体步骤如下: 这里基站侧才艮据物理下行控制信道 PDCCH ( Physical Downlink Control Channel ) 以及小 区公共参考信号 CRS ( Cell-specific Reference Signal ) 配置对应 PDCCH的第一配置信息以及对应 CRS的 第二配置信息中, 包括两种方式, 具体如步骤 401和步骤 402、 步骤 403 以及步骤 404所述: The second embodiment can be based on the embodiment shown in FIG. 1, FIG. 2 or FIG. 3, and the embodiment of the present invention provides a method for configuring signaling resources. Referring to FIG. 4, For the base station to configure the resource mapping process for the EPDCCH when the configuration of the individual subframes changes according to the configuration of the different subframes, the specific steps are as follows: Here, the base station side checks the physical downlink control channel PDCCH (Physical Downlink Control Channel) And the first configuration information corresponding to the PDCCH and the second configuration information of the corresponding CRS are included in the cell-specific reference signal (CRS), and the method includes two methods, specifically, step 401 and step 402, step 403, and step 404. Description:
401、 当仅在第一子帧集中包含 PDCCH 时, 该 EPDCCH 的资 源指示信息包括 PDCCH 所在的第一子帧集以及 PDCCH 占用的 OFDM符号的起始符号数, 以便用户设备根据 EPDCCH 的资源指 示信息正确接收 EPDCCH。 这里根据 EPDCCH 的资源指示信息用于指示用户设备在对
EPDCCH进行资源映射时避开 PDCCH所占用的资源, 在分配每个 资源块 PRB pair中占用的 OFDM时, PDCCH仅占用 PRB pair中 前 1〜3个 0?0^1符号。 其中, 根据 PDCCH生成的 EPDCCH的资 源指示信息可以为, 以一个帧的长度为例, 在子帧集合 1 中第 0 子帧和第 5 子帧中指示 PDCCH 的起始符号数 OFDM 1 ; 在子帧集 合 2 中除第 0子帧和第 5子帧外的其他子帧 (如第 1子帧〜第 4子 帧以及第 6子帧〜第 9子帧 )中指示 PDCCH的起始符号数 OFDM2。 以便于用户设备在根据 EPDCCH的资源指示信息对 EPDCCH配置 资源映射时, 避免占用该 EPDCCH 的资源指示信息中所述的 PDCCH所占用的 OFDM。 其中, 假设 PDCCH仅存在于第一子帧集中, 其中 EPDCCH的 资源指示信息包括 PDCCH所在的子帧以及占用的 OFDM符号的起 始符号数中的一个或组合, 具体以一个帧的长度为例, 假设规定在 第 0子帧与第 5子帧中存在 PDCCH , 其他除过第 0子帧与第 5子 帧中没有 PDCCH , 则在 EPDCCH的资源指示信息中包括: PDCCH 所在的子帧 (如 PDCCH位于第 0子帧与第 5子帧 )、 PDCCH在一 个子帧中的 PRB pair中占用的起始符号数 OFDM中的一个或者组 合。 401. When the PDCCH is included in the first subframe set, the resource indication information of the EPDCCH includes the first subframe set in which the PDCCH is located and the start symbol number of the OFDM symbol occupied by the PDCCH, so that the user equipment according to the resource indication information of the EPDCCH Receive EPDCCH correctly. Here, the resource indication information according to the EPDCCH is used to indicate that the user equipment is in the right When the EPDCCH performs the resource mapping, the resources occupied by the PDCCH are avoided. When the OFDM occupied by each resource block PRB pair is allocated, the PDCCH only occupies the first 1~3 0?0^1 symbols in the PRB pair. The resource indication information of the EPDCCH generated according to the PDCCH may be, for example, the length of one frame, and the number of starting symbols of the PDCCH in the 0th subframe and the 5th subframe in the subframe set 1 is OFDM 1 ; In the frame set 2, other subframes other than the 0th subframe and the 5th subframe (such as the 1st subframe to the 4th subframe and the 6th subframe to the 9th subframe) indicate the number of starting symbols of the PDCCH OFDM2 . When the user equipment is configured to allocate resources to the EPDCCH according to the resource indication information of the EPDCCH, the OFDM occupied by the PDCCH in the resource indication information of the EPDCCH is avoided. It is assumed that the PDCCH is only in the first subframe set, where the resource indication information of the EPDCCH includes one or a combination of the subframe in which the PDCCH is located and the number of starting symbols of the occupied OFDM symbol, specifically taking the length of one frame as an example. It is assumed that the PDCCH is present in the 0th subframe and the 5th subframe, and the PDCCH is not included in the 0th subframe and the 5th subframe. The resource indication information of the EPDCCH includes: a subframe in which the PDCCH is located (such as a PDCCH). One or a combination of the number of starting symbols occupied in the PRB pair of the PDCCH in the 0th subframe and the 5th subframe).
402、 当仅在第一子帧集中包含所述 CRS 时, 该 EPDCCH 的 资源指示信息包括 CRS的端口数、频域偏移位置和 /或存在 CRS的 第一子帧集。 这里 EPDCCH 的 资源指示信息用 于指示用 户 设备在对 EPDCCH进行资源映射时避开 CRS所占用的资源,其中,根据 CRS 生成的 EPDCCH 的资源指示信息可以为, 以一个帧的长度为例, 在子帧集合 1中第 0子帧和第 5子帧中指示 CRS的端口数 1和 CRS 的频域偏移 frequency shift 1 , 在子帧集合 2 中除第 0 子帧和第 5 子帧外的其他子帧(如第 1子帧〜第 4子帧以及第 6子帧〜第 9子帧) 中指示 CRS的端口数 2和 CRS的频域偏移 frequency shift2。 进而 避免在用户设备根据 EPDCCH的资源指示信息为 EDPCCH配置资 源映射时, 占用该 EPDCCH的资源指示信息中所述的 CRS 占用的 资源。
其中, 假设 CRS 仅存在于第一子帧集中, 具体以一个帧的长 度为例, 假设规定在第 0子帧与第 5子帧中存在 CRS , 其他除过第 0子帧与第 5 子帧中没有 CRS , 则在 EPDCCH 的资源指示信息中 包括: CRS所在的子帧 (如 CRS位于第 0子帧与第 5子帧)、 CRS 在一个子帧 中 的端 口数以及 CRS 在一个子帧 中 的频域偏移 frequency shift至少一个或至少两个的组合。 402. When the CRS is included only in the first subframe set, the resource indication information of the EPDCCH includes a port number of the CRS, a frequency domain offset position, and/or a first subframe set in which the CRS exists. Here, the resource indication information of the EPDCCH is used to indicate that the user equipment circumvents the resource occupied by the CRS when performing resource mapping on the EPDCCH, where the resource indication information of the EPDCCH generated according to the CRS may be, for example, the length of one frame, in the sub- The frequency domain offset frequency shift 1 of the port number 1 and the CRS indicating the CRS in the 0th subframe and the 5th subframe in the frame set 1 is other than the 0th subframe and the 5th subframe in the subframe set 2 In the subframes (such as the first subframe to the fourth subframe and the sixth subframe to the ninth subframe), the port number 2 of the CRS and the frequency domain offset frequency shift2 of the CRS are indicated. Further, when the user equipment configures the resource mapping for the EDPCCH according to the resource indication information of the EPDCCH, the resource occupied by the CRS in the resource indication information of the EPDCCH is occupied. It is assumed that the CRS exists only in the first subframe set, and the length of one frame is taken as an example. It is assumed that CRS exists in the 0th subframe and the 5th subframe, and the other 0 subframes and 5 subframes are excluded. If there is no CRS, the resource indication information of the EPDCCH includes: a subframe in which the CRS is located (eg, the CRS is located in the 0th subframe and the 5th subframe), the number of ports in the CRS in one subframe, and the CRS in one subframe. The frequency domain offset frequency shift is at least one or a combination of at least two.
403、 基站向用户设备发送 EPDCCH的资源指示信息, 指示用 户设备根据该 EPDCCH 的资源指示信息确定各子帧信令资源中用 于传输 EPDCCH所占用的资源单位。 这里基站向用户设备发送 EPDCCH 的资源指示信息, 或者根 据用户设备的具体需求发送 EPDCCH的资源指示信息中的 PDCCH 和 /或 CRS。 403. The base station sends the resource indication information of the EPDCCH to the user equipment, and the user equipment is instructed to determine, according to the resource indication information of the EPDCCH, the resource unit used in the transmission of the EPDCCH in each subframe signaling resource. Here, the base station sends the resource indication information of the EPDCCH to the user equipment, or sends the PDCCH and/or CRS in the resource indication information of the EPDCCH according to the specific requirements of the user equipment.
404、 用户设备接收基站发送的物理下行控制信道 EPDCCH的 资源指示信息。 404. The user equipment receives resource indication information of a physical downlink control channel EPDCCH sent by the base station.
这里用户设备接收基站发送的 EPDCCH 的资源指示信息, 或 者根据用户设备的具体需求接收 EPDCCH 的资源指示信息中的 PDCCH和 /或 CRS。 Here, the user equipment receives the resource indication information of the EPDCCH sent by the base station, or receives the PDCCH and/or CRS in the resource indication information of the EPDCCH according to the specific requirements of the user equipment.
405、 用户设备根据该 EPDCCH的资源指示信息接收增强型物 理下行控制信道 EPDCCH。 这里用户设备根据 EPDCCH的资源指示信息对应的 PDCCH和 /或 CRS的配置情况配置 EDPCCH ,避免了在接收 EPDCCH时误用 PDCCH和 /或 CRS所占用的资源 , 从而准确的对 EPDCCH进行接 收。 405. The user equipment receives the enhanced physical downlink control channel EPDCCH according to the resource indication information of the EPDCCH. Here, the user equipment configures the EDPCCH according to the configuration of the PDCCH and/or the CRS corresponding to the resource indication information of the EPDCCH, and avoids the misuse of the resources occupied by the PDCCH and/or the CRS when receiving the EPDCCH, so as to accurately receive the EPDCCH.
具体的,用户设备根据 EPDCCH的资源指示信息为增强型物理 下行控制信道 EPDCCH配置资源映射, 具体步骤如下所述: a、 当接收的 EPDCCH的资源指示信息中 PDCCH仅存在第一 子帧集时, 根据 EPDCCH的资源指示信息接收 EPDCCH。 其中,该 EPDCCH的资源指示信息中 PDCCH 占用的第一子帧 集中的子帧数, 和 PDCCH 占用的 OFDM符号的起始符号数。
这里假设规定在第 0子帧与第 5子帧中存在 PDCCH , 其他除 过第 0子帧与第 5子帧中没有 PDCCH , 则根据 PDCCH所在的子 帧 (如 PDCCH位于第 0子帧与第 5子帧 )、 PDCCH在一个子帧中 的 PRB pair中占用的起始符号数 OFDM , 为 EPDCCH配置资源映 射, 由于已知 PDCCH的起始符号数 OFDM , 则根据现有规定, 在 同一子帧的 PDCCH 占用的 OFDM后面为 EPDCCH配置需要占用 的 OFDM。 b、 当接收的 EPDCCH 的资源指示信息中 CRS 仅存在第一子 帧集时, 根据 EPDCCH的资源指示信息接收 EPDCCH。 其中, EPDCCH 的资源指示信息中 CRS 占用的子帧为第一子 帧集中的子帧, 以及 CRS 占用的端口数和 /或频域偏移位置。 这里假设规定在第 0 子帧与第 5 子帧中存在 CRS , 其他除过 第 0子帧与第 5子帧中没有 CRS ,则根据 CRS所在的子帧(如 CRS 位于第 0子帧与第 5子帧)、 CRS在一个子帧中的端口数以及 CRS 在一个子帧中的频域偏移 frequency shift , 为 EPDCCH配置资源映 射, 由于已知 CRS 所在的子帧、 CRS在一个子帧中的端口数以及 CRS在一个子帧中的频域偏移 frequency shift , 则根据现有规定, 在同一子帧的 PDCCH占用的 OFDM后面以及除 CRS占用的 OFDM 部分为 EPDCCH配置需要占用的 OFDM。 Specifically, the user equipment configures the resource mapping for the enhanced physical downlink control channel EPDCCH according to the resource indication information of the EPDCCH, and the specific steps are as follows: a. When the PDCCH of the received EPDCCH has only the first subframe set in the resource indication information, The EPDCCH is received according to the resource indication information of the EPDCCH. The number of subframes in the first subframe set occupied by the PDCCH in the resource indication information of the EPDCCH, and the number of start symbols of the OFDM symbol occupied by the PDCCH.

Since the number of starting symbols of the PDCCH is known to be OFDM, the same subframe is used according to the existing regulations. The OFDM occupied by the PDCCH is followed by the OFDM required for the EPDCCH configuration. b.
