Description
大带宽***物理上行控制信道资源确定方法及装置 技术领域 本发明涉及通信领域, 具体而言, 涉及一种大带宽***物理上行控制信道资源确 定方法及装置。 背景技术 图 1 是根据相关技术中的 LTE (Long Term Evolution, 长期演进) *** FDD (Frequency Division Duplex, 频分双工)模式的帧结构示意图, 如图 1所示, FDD模 式的帧结构中, 一个 10ms的 radio frame (无线帧) 由二十个长度为 0.5ms, 编号 0~19 的 slot (时隙) 组成, 时隙 2i和 2i+l组成长度为 1ms的 subframe (子帧) i。 图 2是 根据相关技术中的 LTE (Long Term Evolution, 长期演进) *** TDD (Time Division Duplex, 时分双工)模式的帧结构示意图, 如图 2所示, TDD模式的帧结构中, 一个 10ms的 radio frame (无线帧) 由两个长为 5ms的 half frame (半帧) 组成, 一个半帧 包含 5个长为 1ms的 subframe (子帧)。子帧 i定义为 2个长为 0.5ms的时隙 2i和 2i+l。 两种帧结构里, 对于 Normal CP (Normal Cyclic Prefix, 标准循环前缀), 一个时隙包 含 7个长度为 66.7 的符号, 其中第一个符号的 CP长度为 5.21us, 其余 6个符号的 CP长度为 4.69us; 对于 Extended (Extended, 扩展) CP, 一个时隙包含 6个符号, 所 有符号的 CP长度均为 16.67us。 TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method and apparatus for determining a physical uplink control channel resource of a large bandwidth system. 1 is a schematic diagram of a frame structure of an LTE (Long Term Evolution) system FDD (Frequency Division Duplex) mode according to the related art. As shown in FIG. 1 , in a frame structure of an FDD mode, A 10ms radio frame consists of twenty slots (lengths) of length 0~19, and slots 2i and 2i+1 form a subframe of length 1ms. 2 is a schematic diagram of a frame structure according to an LTE (Long Term Evolution) system TDD (Time Division Duplex) mode according to the related art. As shown in FIG. 2, a frame structure of a TDD mode is 10 ms. The radio frame consists of two half frames of 5 ms long. One frame contains five subframes with a length of 1 ms. Subframe i is defined as two time slots 2i and 2i+1 that are 0.5 ms long. In the two frame structures, for Normal CP (Normal Cyclic Prefix), one slot contains seven symbols with a length of 66.7, where the CP length of the first symbol is 5.21us, and the CP length of the remaining six symbols. It is 4.69us; for Extended (Extended) CP, one slot contains 6 symbols, and the CP length of all symbols is 16.67us.
LTE定义了 PDCCH (Physical downlink control channel, 物理下行控制信道)承载 调度分配和其它控制信息; PCFICH (Physical control format indicator channel, 物理控 制格式指示信道)承载在一个子帧里用于传输 PDCCH的 OFDM符号的数目信息, 在 子帧的第一个 OFDM符号上发送, 所在频率位置由***下行带宽与小区 ID决定。 每 个 PDCCH由若干个 CCE (Control Channel Element, 控制信道单元) 组成, 每个子帧 的 CCE数目由 PDCCH的数量和下行带宽决定。 每个子帧的 CCE按照先频域后时域 的顺序编号进行索引。 LTE Release-8定义了 6种带宽: 1.4MHz、3MHz、5MHz、 10MHz、 15MHz和 20MHz。 LTE defines a PDCCH (Physical Downlink Control Channel) bearer scheduling allocation and other control information; a PCFICH (Physical Control Format Indicator Channel) carries an OFDM symbol for transmitting a PDCCH in one subframe. The number information is transmitted on the first OFDM symbol of the subframe, and the frequency position is determined by the system downlink bandwidth and the cell ID. Each PDCCH is composed of a number of CCEs (Control Channel Elements), and the number of CCEs per subframe is determined by the number of PDCCHs and the downlink bandwidth. The CCE of each subframe is indexed according to the sequential number of the time domain after the frequency domain. LTE Release-8 defines six bandwidths: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz.
LTE-Advanced (Further Advancements for E-UTRA)是 LTE Release-8的演进版本。 除满足或超过 3GPP TR 25.913: "Requirements for Evolved UTRA (E-UTRA) and Evolved UTRAN (E-UTRAN) "的所有相关需求外, 还要达到或超过 ITU-R提出的 IMT- Advanced的需求。 其中, 与 LTE Release-8后向兼容的需求是指: LTE Release- 8
的终端可以在 LTE-Advanced的网络中工作; LTE- Advanced的终端可以在 LTE Release-LTE-Advanced (Further Advancements for E-UTRA) is an evolved version of LTE Release-8. In addition to meeting or exceeding all relevant requirements of 3GPP TR 25.913: "Requirements for Evolved UTRA (E-UTRA) and Evolved UTRAN (E-UTRAN)", it also meets or exceeds the requirements of IMT-Advanced proposed by ITU-R. Among them, the requirement for backward compatibility with LTE Release-8 means: LTE Release-8 The terminal can work in the LTE-Advanced network; the LTE-Advanced terminal can be in the LTE Release-
8的网络中工作。 另外, LTE-Advanced应能在不同大小的频谱配置, 包括比 LTE Release-8更宽的 频谱配置 (如 100MHz的连续的频谱资源) 下工作, 以达到更高的性能和目标峰值速 率。 由于 LTE-Advanced网络需要能够接入 LTE用户, 所以其操作频带需要覆盖目前 LTE 频带, 在这个频段上已经不存在可分配的连续 100MHz 的频谱带宽。 所以 LTE-Advanced 需要解决的一个直接技术是将几个分布在不同频段上的连续分量载频 (频谱) (Component carrier)聚合起来形成 LTE-Advanced可以使用的 100MHz带宽。 即对于聚集后的频谱, 被划分为 n个分量载频(频谱)(Component carrier), 每个分量 载频 (频谱) 内的频谱是连续的。 图 3是根据相关技术中的频谱配置的示意图, 如图 3所示, 频谱配置的方案主要 有 3种, 如图 3所示。 其中, 方格部分为与 LTE Release-8兼容的***带宽, 斜线部分 为 LTE-Advanced专有的***带宽。 图 3a为频谱配置方案 1, 是指 LTE-Advanced频谱 配置由 1个 LTE-Advanced定义的***带宽组成,且该带宽大于 LTE Release- 8定义的 ***带宽。图 3b为频谱配置方案 2,是指 LTE-Advanced频谱配置由一个 LTE Release- 8 定义的***带宽和多个 LTE-Advanced 定义的***带宽通过频谱聚集 (carrier aggregation)组成。 图 3c为频谱配置方案 3, 是指 LTE-Advanced频谱配置由多个 LTE Release-8定义的***带宽通过频谱聚集 (carrier aggregation) 组成, 其中, 上述频谱 的聚集可以是连续频谱的聚集, 也可以是不连续频谱的聚集。 LTE Release-8 UE能够 接入兼容 LTE Release-8的频带, LTE-AUE即能够接入 LTE Release-8兼容的频带, 也 能够接入 LTE-Advanced的频带。 考虑到与 LTE Release-8的兼容性, LTE-Advanced各分量载频都需要满足可以接 入 LTE用户, 这需要保证在每个分量载频的信道结构尽量保持与 LTE—致。 目前, LTE-Advanced在 FDD双工模式下, 上行和下行的可用分量载频数目可以 不一样, 这样, 每个下行分量载频就不能——对应上行控制信道 PUCCH (Physical uplink control channel, 物理上行控制信道), LTE已经设计的 PUCCH资源索引就无法 正确工作。 目前 LTE FDD双工模式下动态调度 PDSCH设计的在上行发送 HARQ-ACK的 PUCCH资源索引是通过调度的下行子帧上分配给该用户的 PDCCH的最小 CCE隐含 映射的。 gp " ccH = "CCE + A¾ CCH, 其中" ^CCH是用户发送 HARQ-ACK的 PUCCH资源
索引, "CCE是对应传输 PDCCH的第一个 CCE索引, VPUCCH由高层配置。 对半静态调 度的 PDSCH, "PUCCH由高层配置。 对 LTE TDD双工模式动态调度的 PDSCH, 上行发送 HARQ-ACK的 PUCCH资 源索引是通过调度的下行子帧上分配给该用户的 PDCCH的 CCE经过块交织后得到。 由于 TDD模式下会存在一个无线帧中下行子帧数目多于上行子帧数目的配置,所以定 义了反馈窗的概念。反馈窗即上行子帧对应的所有下行子帧(需要说明的是,此处的 "对 应"是指这些下行子帧均在该上行子帧反馈确认信息)。 对于 TDD双工模式,由于可能存在在一个无线帧中下行子帧大于上行子帧的配置 场景, 所以可能存在多个下行子帧的反馈信息在同一个上行子帧中发送。 这样的一个 上行子帧对应的多个下行子帧称为反馈窗。 Working in the network of 8. In addition, LTE-Advanced should be able to operate in different spectrum configurations, including a wider spectrum configuration than LTE Release-8 (such as 100 MHz of continuous spectrum resources) to achieve higher performance and target peak rates. Since the LTE-Advanced network needs to be able to access LTE users, its operating band needs to cover the current LTE frequency band, and there is no allocated 100 MHz spectrum bandwidth that can be allocated in this frequency band. Therefore, a direct technology that LTE-Advanced needs to solve is to aggregate several consecutive component carrier carriers distributed in different frequency bands to form a 100 MHz bandwidth that can be used by LTE-Advanced. That is, for the aggregated spectrum, it is divided into n component carrier carriers, and the spectrum in each component carrier frequency (spectrum) is continuous. FIG. 3 is a schematic diagram of a spectrum configuration according to the related art. As shown in FIG. 3, there are mainly three schemes for spectrum configuration, as shown in FIG. 3. Among them, the grid part is the system bandwidth compatible with LTE Release-8, and the slash part is the system bandwidth of LTE-Advanced. 3A is a spectrum configuration scheme 1, which means that the LTE-Advanced spectrum configuration is composed of a system bandwidth defined by one LTE-Advanced, and the bandwidth is greater than the system bandwidth defined by LTE Release-8. Figure 3b shows the spectrum configuration scheme 2, which means that the LTE-Advanced spectrum configuration consists of a system bandwidth defined by one LTE Release-8 and a system bandwidth defined by multiple LTE-Advanceds through carrier aggregation. Figure 3c shows the spectrum configuration scheme 3, which refers to the LTE-Advanced spectrum configuration. The system bandwidth defined by multiple LTE Release-8s is composed of carrier aggregation. The aggregation of the foregoing spectrum may be continuous spectrum aggregation or It is the aggregation of discontinuous spectrum. The LTE Release-8 UE can access the LTE Release-8 compatible frequency band, and the LTE-AUE can access the LTE Release-8 compatible frequency band and also access the LTE-Advanced frequency band. Considering the compatibility with LTE Release-8, each component carrier frequency of LTE-Advanced needs to be able to access LTE users, which needs to ensure that the channel structure of each component carrier frequency is kept as close as possible to LTE. At present, in the FDD duplex mode, the number of available component carrier frequencies of the uplink and downlink can be different, so that each downlink component carrier frequency cannot be used - corresponding to the uplink control channel PUCCH (Physical uplink control channel, physical uplink) Control channel), the PUCCH resource index that LTE has designed cannot work properly. Currently, the PUCCH resource index for transmitting the HARQ-ACK in the uplink in the LTE FDD duplex mode is dynamically mapped by the minimum CCE allocated to the PDCCH of the user in the scheduled downlink subframe. Gp " cc H = " CCE + A 3⁄4 CCH , where " ^CCH is the PUCCH resource for the user to send HAR Q- AC K Index, " CCE is the first CCE index corresponding to the transmission PDCCH, and V PUCCH is configured by the upper layer. For the semi-statically scheduled PDSCH, " PUCCH is configured by the upper layer. For the PDSCH that is dynamically scheduled in the LTE TDD duplex mode, the PUCCH resource index of the uplink HARQ-ACK is obtained by block interleaving the CCEs of the PDCCH allocated to the user in the scheduled downlink subframe. Since there is a configuration in the TDD mode that the number of downlink subframes is larger than the number of uplink subframes in a radio frame, the concept of a feedback window is defined. The feedback window is all the downlink subframes corresponding to the uplink subframes. It should be noted that the “correspondence” here means that the downlink subframes are fed back the acknowledgement information in the uplink subframe. For the TDD duplex mode, there may be a configuration scenario in which the downlink subframe is larger than the uplink subframe in one radio frame. Therefore, feedback information of multiple downlink subframes may be sent in the same uplink subframe. A plurality of downlink subframes corresponding to such an uplink subframe are referred to as a feedback window.

At present, in the continuous evolution of LTE-Advanced, the demand for the number of users for system expansion is increasing, and the existing physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) can no longer meet the requirements of more advanced wireless communication. For the requirements of the system, the 3GPP introduces an ePDCCH (Enhanced PDCCH) channel to enhance the PDCCH performance, and introduces a new transmission PDCCH region. In this case, how to obtain the transmission ACK/NACK corresponding to the PDSCH of the ePDCCH Physically The Physical Uplink Control Channel (PUCCH) resource is called a problem to be solved.

Virtual resource block index. FIG. 8 is a schematic diagram of a continuous mapping according to a preferred embodiment of the present invention. As shown in FIG. 8, the resource mapping of the PUCCH is also designed to design a new resource region based on the mapping region of the R8 system, and the parameter cH is introduced to obtain the resource location, and may also be in the R8. The resource region is obtained by introducing (the total CCE of each downlink subframe corresponding to the uplink subframe) to obtain the final mapping resource. 3.

As shown in FIG. 9, the resource mapping of the PUCCH is also designed to design a new resource region based on the mapping region of the R8 system, and the parameter cH is introduced to obtain the resource location. The final mapping resource is obtained by introducing (the CCE sum of each downlink subframe corresponding to the uplink subframe) in the R8 resource region. The LTE-Advanced needs to be compatible with LTE users. If the LTE-Advanced aggregated carrier includes the LTE frequency band, the LTE user can access the LTE-Advanced network in the uplink and downlink frequency bands used by the LTE. At this time, the mapping method of the LTE user uplink control channel accessing the LTE-Advanced network is completely the same as the LTE design.

For LTE-Advanced users, the channel resource index of the PUCCH is jointly determined by the high-level configuration parameters and the DCI dynamic signaling. In the ^CCH, the DCI dynamic signaling may be through the newly added ARI domain, or may be through its existing TPC. For example, the channel resource index "TM of the PUCCH carrying the ACK/NACK of the PDSCH is jointly determined according to the newly added ARI domain of the higher layer signaling W^CCH and the DCI signaling, wherein the W^CCH configures a group of PUCCH resources, The ARI indicates a specific one of the PUCCH resources in the PUCCH resource group. For example, the upper layer parameter ^^^ configures 4 available PUCCH resources, and the ARI field in the DCI signaling is '00', then "is the first of the 4 available PUCCH resources; for example, if the upper layer parameter W^ The CCH is configured with 4 available PUCCH resources, and the ARI field in the DCI signaling is '10', then " CCH is the third of the 4 available PUCCH resources. For example, the CCH is determined according to an existing indication field in the CCH and DCI signaling, such as a TPC domain, where the WCHC is configured with a PUCCH-group resource, and the TPC indicates a specific corresponding in the PUCCH resource group. A PUCCH resource. For example, the upper layer parameter ^^^ configures 4 available PUCCH resources, and the TPC field in the DCI signaling is '00', then ^CCH is the first of the 4 available PUCCH resources; for example, if the upper layer parameter A3⁄4 The CCH is configured with 4 available PUCCH resources. The TPC field in the DCI signaling is '10', then "is the third of the 4 available PUCCH resources. For the LTE-Advanced FDD system user, the PUCCH channel resource index can be Obtained in different ways, the following describes the manner of implicit mapping in the newly designed PUCCH region.

"The VRI is mapped in other interleaving manners in units of VR. It is assumed that one uplink subframe corresponds to four downlink subframes, and each The corresponding VR on the downlink subframe is shown in Figure 6. VRBI represents the virtual resource block index composed of VR. The mapping of other interleaving modes in VR is shown in Figure 9. The channel resource index for PUCCH is based on the upper layer. The manner in which the ARI domain in the signaling and the DCI signaling are jointly determined is different in the manner in which the primary downlink carrier configuration and the secondary downlink carrier configuration are different. For the LTE-Advanced system user, the UE is configured in In the carrier aggregation scenario, the UE is configured to aggregate two downlink CCs at a certain time, and the UE sends a feedback message in PUCCH format 3 on the uplink. The primary downlink carrier is configured with an ePDCCH or a PDCCH, and the secondary downlink carrier is configured with an ePDCCH. That is, the UE receives the PDSCH of the two carriers in the downlink, and the channel resource index of the PUCCH that carries the ACK/NACK of the PDSCH is jointly determined according to the ARI domain in the high layer signaling and the DCI signaling, where the high layer signaling configuration is a group of PUCCH resources, the ARI field indicates a specific one of the PUCCH resources in the PUCCH resource group. The RP domain reuses the TPC domain of the ePDCCH of the secondary component carrier. If the system is a TDD system, the main component carrier is divided by the counter field DAI=1. The TPC of the other PDCCH/ePDCCH is also used as the ARI. For the LTE-Advanced system user, the UE is configured in the carrier aggregation scenario, assuming that the UE is configured to aggregate two downlink CCs at a certain moment, and the UE adopts PUCCH format 3 in the uplink. The feedback message is sent, where the primary downlink carrier is configured with the ePDCCH, and the secondary downlink carrier is configured with the PDCCH. That is to say, the UE receives the PDSCH of the two carriers at the same time, and the channel resource index of the PUCCH carrying the ACK/NACK of the PDSCH is according to the upper layer. The ARI domain in the signaling and the DCI signaling is jointly determined, where the high layer signaling configures a group of PUCCH resources, and the ARI domain indicates a PUCCH corresponding to the PUCCH resource group. The TPC domain implementation of the PDCCH of the ARI domain reusing the secondary component carrier. If the system is a TDD system, the TPC of the other PDCCH/ePDCCH except the counter field DAI=1 on the primary component carrier is also used as the ARI. The FDD system user, the UE is configured in a carrier aggregation scenario, assuming that the UE is configured to aggregate two downlink CCs at a certain time, and the UE transmits a feedback message in the uplink using the PUCCH format 1 channel selection mode. When indicated, a group of PUCCH resources are configured by high layer signaling, and one of the resources is indicated by the ARI field of the PDCCH/ePDCCH in the secondary component carrier. The PDCCH/ePDCCH or the secondary component carrier dynamically scheduled on the primary component carrier For the PDCCH/ePDCCH without the cross-carrier scheduling, or the PDCCH/ePDCCH carrying the SPS release message on the primary component carrier, for the downlink transmission modes 1, 2, 5, 6, and 7, the PUCCH resource carries the PDCCH/ePDCCH. First One CCE implicit mapping; then for downlink transmission modes 1, 3, 4, 8 and 9, PUCCH resources are implicitly mapped by the first CCE carrying the PDCCH/ePDCCH and the first CCE+1. For the PDSCH transmission and transmission modes 1, 2, 5, 6 and P 7 of the semi-persistent scheduling of the primary carrier, the PUCCH resource is the SPS resource notified by the upper layer; for the transmission mode 3, 4, 8 and 9, the first PUCCH The resource is the SPS resource notified by the upper layer, and the second PUCCH resource is obtained according to the implicit mapping of the first SPS resource. For the LTE-Advanced TDD system user, the UE is configured in a carrier aggregation scenario. Assume that the UE is configured to aggregate two downlink CCs at a certain time, and the UE sends a feedback message in the uplink using the PUCCH format 1 channel selection mode. The PUCCH resource carrying the feedback message is determined as follows: If there is cross-carrier scheduling, and the PDSCH transmission of the primary component carrier is indicated by the corresponding PDCCH, the first CCE corresponding to the PDCCH of the DAI domain equal to 1 and 2 in the primary component carrier corresponds to Two PUCCH resources are obtained. If the PDSCH transmission is not indicated by the corresponding PDCCH, the two PUCCH resources in the primary component carrier correspond to the first CCE of the PDCCH/ePDCCH from the SPS reserved resource and the DAI is equal to 1. The two PUCCH resources of the secondary component carrier are from the first CCE corresponding to the PDCCH/ePDCCH with DAI equal to 1 and P 2 . If there is no cross-carrier scheduling, and the PDSCH transmission of the primary component carrier is indicated by the corresponding PDCCH/ePDCCH, the first CCE of the PDCCH/ePDCCH in which the DAI domain is equal to 1 and P 2 in the primary component carrier obtains two PUCCH resources, Or, if the PDSCH transmission is not indicated by the corresponding PDCCH, the two PUCCH resources in the primary component carrier correspond to the first CCE of the PDCCH/ePDCCH from the SPS reserved resource and the DAI is equal to 1. The two PUCCH resources of the secondary component carrier are from the indication of the ARI. The ARI is a TPC domain that reuses the PDCCH/ePDCCH.
