[0044] 基于系统带宽对应的PRB数量以及每一个子频带带宽对应的PRB的数量,可以确定本示例对应的协议中的上述表1限定的传输模式场景下;进一步地,基于每一个子频带包含的PRB的数量就能够确定M。 [0044] Based on the number of PRB corresponding to the system bandwidth and the bandwidth of each sub-band corresponding to the PRB, the present example can determine the corresponding protocol defined in Table 1 transmission mode scene; further, based on each sub-band comprising the number of the PRB can be determined M.

[0045] 需要理解的是,每一个PRB可以包含有7*12个资源元素(RE,Resource Element), 也就是对应了7个时域上的符号、以及12频域上的子载波,每一个RE即对应1个时域符号以及1个频域子载波;如果需要承载一个32端口的CSI-RS信号,就需要至少32个RE。 [0045] to be understood that each PRB may contain 7 * 12 resource elements (RE, Resource Element), which is corresponding to the symbol on the 7 time domain and a subcarrier 12 on the frequency domain, each of RE i.e. corresponding to a time domain symbol and a frequency domain subcarrier; if necessary carrying a CSI-RS signal port 32, you need at least 32 RE. 由于本实施例中设置在每一个PRB中选取时域上连续的两个符号,那么就是说,在频域上至少选取16 个子载波的RE才能够承载一个32端口的CSI-RS信号。 Since the present embodiment is provided on the selected two consecutive symbols in the time domain in each PRB, then that, in the frequency domain to select at least RE 16 sub-carriers to be able to carry a CSI-RS signal port 32.

[0050]基于系统带宽对应的PRB数量以及每一个子频带带宽对应的PRB的数量,可以确定本示例对应的协议中的上述表1限定的传输模式场景下;进一步地,基于每一个子频带包含的PRB的数量就能够确定M。 [0050] Based on the number of PRB corresponding to the system bandwidth and the bandwidth of each sub-band corresponding to the PRB, the present example can determine the corresponding protocol defined in Table 1 transmission mode scene; further, based on each sub-band comprising the number of the PRB can be determined M.

[0051 ] 需要理解的是,每一个PRB可以包含有7*12个资源元素(RE,Resource Element), 也就是对应了7个时域上的符号、以及12频域上的子载波,每一个RE即对应1个时域符号以及1个频域子载波;如果需要承载一个32端口的CSI-RS信号,就需要至少32个RE。 [0051] to be understood that each PRB may contain 7 * 12 resource elements (RE, Resource Element), which is corresponding to the symbol on the 7 time domain and a subcarrier 12 on the frequency domain, each of RE i.e. corresponding to a time domain symbol and a frequency domain subcarrier; if necessary carrying a CSI-RS signal port 32, you need at least 32 RE. 由于本实施例中设置在每一个PRB中选取时域上连续的两个符号,那么就是说,在频域上至少选取16 个子载波的RE才能够承载一个32端口的CSI-RS信号。 Since the present embodiment is provided on the selected two consecutive symbols in the time domain in each PRB, then that, in the frequency domain to select at least RE 16 sub-carriers to be able to carry a CSI-RS signal port 32.

[0054] 不例一中System bandwith= =8_26RBs,Subband size k= = 2RBs: —个Subband 的2个PRB中包含一个完整的32port CSI-RS,密度为0.5RE/port/PRB。 [0054] In an embodiment not System bandwith = = 8_26RBs, Subband size k = = 2RBs: - 2 Subband two PRB pairs contained a complete 32port CSI-RS, density 0.5RE / port / PRB.

[0057] 可见,通过采用上述方案,能够从每一个子频带中选取连续的物理资源块,将M个32端口的CSI-RS信号映射到选取的物理资源块中并传输。 [0057] Therefore, with the above-described embodiment, it is possible to select consecutive physical resource blocks from each of the subbands, the M signal CSI-RS port 32 is mapped to physical resource block selected and transmitted. 如此,就能够从子频带中的连续的物理资源块传输32端口的CSI-RS信号,使得其密度较高,从而保证了32端口的CSI-RS信号的覆盖性能。 Thus, it can be transmitted from the sub-band of consecutive physical resource blocks CSI-RS signal port 32, so that a higher density, so as to ensure the coverage performance of a CSI-RS port 32 signal.

[0058] 具体来说,能够从每一个子频带对应的物理资源块中选取第二时隙,并从第二时隙中选取两个目标符号,最终将M个32端口的CSI-RS信号映射到选取的目标符号中并传输。 [0058] Specifically, each sub-band can be selected from the physical resource block corresponding to a second time slot, and select two symbols from a second target slot, eventually the M signal mapping CSI-RS port 32 to select the target symbol and transmitted. 如此,就能够从每一个物理资源块的第二时隙中将近40个资源元素中进行挑选,并且将M个CSI-RS信号映射到挑选的资源元素后,使得其密度较高,从而保证了32端口的CSI-RS信号的覆盖性能。 Thus, it is possible to carry out a second time slot from each physical resource block almost 40 resource elements selected, and the mapping of the M signals to the CSI-RS resource elements selected so that a higher density, thus ensuring 32 CSI-RS signal coverage performance port.

[0139] 另外,本实施例具体提供确定M的数量的方式,如下: [0139] Further, this embodiment particularly provides a way to determine the number of M, as follows:

[0140] 信号处理单元62,用于基于系统带宽对应的PRB的数量、以及每一个子频带包含的PRB的数量K,确定所述K个PRB中能够传输的32端口的CS I-RS信号的数量M。 [0140] The signal processing unit 62, based on the number of PRB of the system bandwidth corresponding to the number of PRB, and each of the K sub-bands comprising, CS 32 determines the K PRB port capable of transmitting a signal I-RS the number of M.

[0141] 进一步地,本实施例结合上述表2、以下面三种示例进行确定M的操作的详细说明: [0141] Further, the present embodiment described in detail above in conjunction with Table 2, the following operation in three exemplary embodiment M is determined:

[0142] 示例一、 [0142] Example I.

[0143] 所述信号处理单元62,用于当系统带宽对应的PRB的数量处于第一阈值范围内、且所述每一个子频带包含的PRB的数量为四个时,确定所述K个PRB中能够传输的32端口的CSI-RS信号的数量M为三,其中,所述第一阈值范围可以为大于等于八且小于等于二十六。 [0143] The signal processing unit 62 for, when the number of PRB corresponding to the system bandwidth is within a first threshold range, and the number of PRB for each subband contains four, PRB determine the K in the number capable of transmitting signals M CSI-RS port 32 is three, wherein the first threshold range may be greater than or equal to eight or less (No.26).

[0144] 基于系统带宽对应的PRB数量以及每一个子频带带宽对应的PRB的数量,可以确定本示例对应的协议中的上述表2限定的传输模式场景下;进一步地,基于每一个子频带包含的PRB的数量就能够确定M。 [0144] Based on the number of PRB transmission mode corresponding to the system bandwidth and the bandwidth of each sub-band corresponding to the PRB, the present example can determine the corresponding protocol as defined in Table 2 scene; further, based on each sub-band comprising the number of the PRB can be determined M.

[0145] 需要理解的是,每一个PRB可以包含有7*12个资源元素(RE,Resource Element), 也就是对应了7个时域上的符号、以及12频域上的子载波,每一个RE即对应1个时域符号以及1个频域子载波;如果需要承载32端口的CSI-RS信号,就需要至少32个RE。 [0145] to be understood that each PRB may contain 7 * 12 resource elements (RE, Resource Element), which is corresponding to the symbol on the 7 time domain and a subcarrier 12 on the frequency domain, each of RE i.e. corresponding to a time domain symbol and a frequency domain subcarrier; if desired carrier signal CSI-RS port 32, you need at least 32 RE.

[0146] 由于本实施例中设置在每一个PRB中选取时域上连续的两个符号,那么就是说,在频域上至少选取16个子载波的RE才能够承载一个32端口的CSI-RS信号。 [0146] Since the present embodiment is provided in each PRB selected two consecutive symbols in the time domain, so to say, in the frequency domain to select at least 16 sub-carriers of the RE to be able to carry a CSI-RS signal port 32 .

[0147] 比如,系统带宽(System bandwidth) :8_26,某一个子频带(subband)包括4RBs: — 个Subband的4个PRB中包含3个完整的32port CSI-RS,密度为0.75RE/port/PRB。 [0147] For example, the system bandwidth (System bandwidth): 8_26, certain subbands (Subband) comprising 4RBs: - 4 PRB-one Subband contains three complete 32port CSI-RS, density 0.75RE / port / PRB .

[0148] 示例二、 [0148] Example II.

[0149] 所述信号处理单元62,用于当系统带宽对应的PRB的数量处于第二阈值范围内、且所述每一个子频带包含的PRB的数量为三个时,确定所述K个PRB中能够传输的32端口的CSI-RS信号的数量M为二,其中,所述第二阈值范围可以为大于等于二十七且小于等于六十_-O [0149] The signal processing unit 62 for, when the number of PRB corresponding to the system bandwidth is within a second threshold range, and the number of PRB each sub-band including three for determining the K PRB number M CSI-RS port 32 in the signal can be transmitted is two, wherein the second threshold range may be greater than or equal to and less than or equal to sixty twenty-seven _-O

[0150] 基于系统带宽对应的PRB数量以及每一个子频带带宽对应的PRB的数量,可以确定本示例对应的协议中的上述表1限定的传输模式场景下;进一步地,基于每一个子频带包含的PRB的数量就能够确定M。 [0150] Based on the number of PRB corresponding to the system bandwidth and the bandwidth of each sub-band corresponding to the PRB, the present example can determine the corresponding protocol defined in Table 1 transmission mode scene; further, based on each sub-band comprising the number of the PRB can be determined M.

[0151] 需要理解的是,每一个PRB可以包含有7*12个资源元素(RE,Resource Element), 也就是对应了7个时域上的符号、以及12频域上的子载波,每一个RE即对应1个时域符号以及1个频域子载波;如果需要承载一个32端口的CSI-RS信号,就需要至少32个RE。 [0151] to be understood that each PRB may contain 7 * 12 resource elements (RE, Resource Element), which is corresponding to the symbol on the 7 time domain and a subcarrier 12 on the frequency domain, each of RE i.e. corresponding to a time domain symbol and a frequency domain subcarrier; if necessary carrying a CSI-RS signal port 32, you need at least 32 RE. 由于本实施例中设置在每一个PRB中选取时域上连续的两个符号,那么就是说,在频域上至少选取16 个子载波的RE才能够承载一个32端口的CSI-RS信号。 Since the present embodiment is provided on the selected two consecutive symbols in the time domain in each PRB, then that, in the frequency domain to select at least RE 16 sub-carriers to be able to carry a CSI-RS signal port 32.

[0152] 比如,系统带宽(System bandwidth): 27-63,某一个子频带(subband)包括6个PRB 中包含4个完整的32port CSI-RS,密度为0·67RE/port/PRB。 [0152] For example, the system bandwidth (System bandwidth): 27-63, certain subbands (Subband) comprises six PRB contains four complete 32port CSI-RS, a density of 0 · 67RE / port / PRB.

[0153] 示例三、 [0153] Example III.

[0154] 所述信号处理单元62,用于当系统带宽对应的PRB的数量处于第三阈值范围内、且所述每一个子频带包含的PRB的数量为四个时,确定所述K个PRB中能够传输的32端口的CSI-RS信号的数量M为三,其中,所述第三阈值范围可以为大于等于六十四且小于等于110。 [0154] The signal processing unit 62 for, when the number of PRB corresponding to the system bandwidth is within the third threshold range, and the number of PRB for each sub-band including four for determining the K PRB in the number capable of transmitting signals M CSI-RS port 32 is three, wherein the third threshold range can be greater than or equal sixty-four 110 or less.

[0155] 基于系统带宽对应的PRB数量以及每一个子频带带宽对应的PRB的数量,可以确定本示例对应的协议中的上述表1限定的传输模式场景下;进一步地,基于每一个子频带包含的PRB的数量就能够确定M。 [0155] Based on the number of PRB corresponding to the system bandwidth and the bandwidth of each sub-band corresponding to the PRB, the present example can determine the corresponding protocol defined in Table 1 transmission mode scene; further, based on each sub-band comprising the number of the PRB can be determined M.

[0156] 需要理解的是,每一个PRB可以包含有7*12个资源元素(RE,Resource Element), 也就是对应了7个时域上的符号、以及12频域上的子载波,每一个RE即对应1个时域符号以及1个频域子载波;如果需要承载一个32端口的CSI-RS信号,就需要至少32个RE。 [0156] to be understood that each PRB may contain 7 * 12 resource elements (RE, Resource Element), which is corresponding to the symbol on the 7 time domain and a subcarrier 12 on the frequency domain, each of RE i.e. corresponding to a time domain symbol and a frequency domain subcarrier; if necessary carrying a CSI-RS signal port 32, you need at least 32 RE. 由于本实施例中设置在每一个PRB中选取时域上连续的两个符号,那么就是说,在频域上至少选取16 个子载波的RE才能够承载一个32端口的CSI-RS信号。 Since the present embodiment is provided on the selected two consecutive symbols in the time domain in each PRB, then that, in the frequency domain to select at least RE 16 sub-carriers to be able to carry a CSI-RS signal port 32.

[0157] 比如,系统带宽(System bandwidth) :27_63,某一个子频带(subband)包括一个Subband的8个PRB中包含6个完整的32port CSI-RS,密度为0.75RE/port/PRB。 [0157] For example, the system bandwidth (System bandwidth): 27_63, certain subbands (Subband) comprises a PRB Subband 8 contains six complete 32port CSI-RS, density 0.75RE / port / PRB.

[0158] 可见,通过采用上述方案,能够从每一个子频带中选取连续的物理资源块,将M个32端口的CSI-RS信号映射到选取的物理资源块中并传输。 [0158] Therefore, with the above-described embodiment, it is possible to select consecutive physical resource blocks from each of the subbands, the M signal CSI-RS port 32 is mapped to physical resource block selected and transmitted. 如此,就能够从子频带中的连续的物理资源块传输32端口的CSI-RS信号,使得其密度较高,从而保证了32端口的CSI-RS信号的覆盖性能。 Thus, it can be transmitted from the sub-band of consecutive physical resource blocks CSI-RS signal port 32, so that a higher density, so as to ensure the coverage performance of a CSI-RS port 32 signal.
