在5G网络中确定PDSCH资源的分配通过以下表进行查询,其具体定义如下: 表5.1.2.1.1-1和表5.1.2.1.1-1A定义了要应用的PDSCH时域资源分配配置。 应用根据表5.1.2.1.1-2、5.1.2.1.1-3、5.1.2.1.1-4 和 5.1.2.1.1-5 的默认PDSCH时域分配A、B或C,或者更高层配置 pdsch-TimeDomainAllocationList 或 [pdsch-TimeDomainAllocationListForMultiPDSCH-r17] 或 pdsch-TimeDomainAllocationListDCI-1-2 被应用。 对于在频率范围 1 中使用共享频谱信道访问的操作,如 [16,TS 37.213] 中所述,UE 将表 5.1.2.1.1-2 第 9 行中的 S 和 L 重新解释为 S=6 和 L=7。 Table 5.1.2.1.1-1: Applicable PDSCH time domain resource allocation for DCI formats 1_0, 1_1, 4_0, 4_1 and 4_2 RNTI | PDCCH search space | SS/PBCH block and CORESET multiplexing pattern | PDSCH-ConfigCommon includes pdsch-TimeDomainAllocationList | PDSCH-Config includes pdsch-TimeDomainAllocationList | PDSCH-Config-MCCH/PDSCH-Config-MTCH includes pdsch-TimeDomainAllocationList Or pdsch-Config-Multicast includes pdsch-TimeDomainAllocationList | PDSCH-Config includes pdsch-TimeDomainAllocationListForMultiPDSCH-r17 | PDSCH time domain resource allocation to apply | SI-RNTI | Type0 common | 1 | - | - | - | - | Default A for normal CP | 2 | - | - | - | - | Default B | 3 | - | - | - | - | Default C | SI-RNTI | Type0A common | 1 | No | - | - | - | Default A | 2 | No | - | - | - | Default B | 3 | No | - | - | - | Default C | 1,2,3 | Yes | - | - | - | Pdsch-TimeDomainAllocationList provided in PDSCH-ConfigCommon | RA-RNTI, MSGB-RNTI, TC-RNTI | Type1 common | 1,2,3 | No | - | - | - | Default A | 1,2,3 | Yes | - | - | - | Pdsch-TimeDomainAllocationList provided in PDSCH-ConfigCommon | P-RNTI | Type2 common | 1 | No | - | - | - | Default A | 2 | No | - | - | - | Default B | 3 | No | - | - | - | Default C | 1,2,3 | Yes | - | - | - | Pdsch-TimeDomainAllocationList provided in PDSCH-ConfigCommon | MCCH-RNTI | Type 0/0B common for broadcast | 1 | No | - | No | - | Default A | 2 | No | - | No | - | Default B | 3 | No | - | No | - | Default C | 1,2,3 | Yes | - | No | - | pdsch-TimeDomainAllocationList provided in PDSCH-ConfigCommon | 1,2,3 | No/Yes | - | Yes | - | pdsch-TimeDomainAllocationList provided in pdsch-Config-MCCH | G-RNTI for broadcast | Type 0/0B common for broadcast | 1 | No | - | No | - | Default A | 2 | No | - | No | - | Default B | 3 | No | - | No | - | Default C | 1,2,3 | Yes | - | No | - | pdsch-TimeDomainAllocationList provided in PDSCH-ConfigCommon | 1,2,3 | No/Yes | - | Yes | - | pdsch-TimeDomainAllocationList provided in PDSCH-Config-MTCH, if configured, otherwise TimeDomainAllocationList provided in PDSCH-Config-MCCH | C-RNTI, MCS-C-RNTI, CS-RNTI | Any common search space associated with CORESET 0 | 1, 2, 3 | No | - | - | - | Default A | 1, 2, 3 | Yes | - | - | - | pdsch-TimeDomainAllocationList provided in PDSCH-ConfigCommon | C-RNTI, MCS-C-RNTI, CS-RNTI | Any common search space not associated with CORESET 0 UE specific search space | 1,2,3 | No | No | - | - | Default A | 1,2,3 | Yes | No | - | - | pdsch-TimeDomainAllocationList provided in PDSCH-ConfigCommon | 1,2,3 | No/Yes | Yes | - | - | pdsch-TimeDomainAllocationList provided in PDSCH-Config | 1,2,3 | No/Yes | - | - | Yes | pdsch-TimeDomainAllocationListForMultiPDSCH-r17 provided in PDSCH-Config (Note 2) | G-RNTI, G-CS-RNTI (for multicast) | Type-X common search space for multiast | 1,2,3 | No | - | No | - | Default A | 1,2,3 | Yes | - | No | - | pdsch-TimeDomainAllocationList provided in PDSCH-ConfigCommon (Note 1) | 1,2,3 | No/Yes | - | Yes | - | pdsch-TimeDomainAllocationList provided in pdsch-Config-Multicast (Note 1) |
