Description

一种 PUSCH的资源映射方法， 装置 技术领域 本发明涉及无线通信领域， 特别涉及一种 PUSCH的资源映射方法与装 置。 背景技术
在现有的 3GPP E-UTRA系统中， 在载波聚合情况下， 不支持 SRS和 PUSCH ( hysical downlink data share channel , 物理下行数据共享信道) /PUCCH信道（physical downlink control channel, 物理下行控制信道）在 同一个时刻进行传输。如果某个载波的 SRS和其他载波的 PUSCH同时出现 在一个子帧的最后一个符号上， 则 UE不发送 SRS, 本载波上的 PUSCH映 射在所分配的全部 RE上， 不需要做 rate matching (速率匹配）， 如图 1所示。 在同一个载波里， 如果 UE在某个子帧的最后一个符号有 SRS传输， 且该子 帧里有 PUSCH传输， 那么 PUSCH不在最后一个符号上发送， 即 PUSCH按 照 n-1个符号进行速率匹配后映射到该子帧 n个符号的前 n-1个符号上。 或 者在同一个载波里， 如果在某个子帧的最后一个符号配置有小区级的 SRS 带宽， PUSCH在频域上部分或全部和该带宽重叠， 那么 PUSCH按照 n个符 号进行速率匹配后映射到该子帧 n个符号符号上。 由于 eNB确切知道 SRS是否发送， 因此对于 PUSCH按照何种方式进 行速率匹配不存在模糊度问题。 然而在 LTE Rel-11版本中，如果 UE被配置了多个 TAG ( time advanced group )，则可以支持 SRS和 PUSCH/PUCCH在不同载波上的同传， 只有当 SRS和 PUSCH/PUCCH的功率之和超过预先设定的功率上限时， 才不发送 SRS。 这种情况导致了 UE有时发送 SRS, 有时因为功率受限而不发 SRS, 由于 eNB并不知道 UE是否功率受限， 按照现有协议， 会导致 eNB无法明 确和 SRS在同一载波传的 PUSCH按照多少个符号进行速率匹配操作。 发明内容
本发明实施例的目的是提供一种 PUSCH的资源映射方法与装置， 能够 在支持 SRS和 PUSCH/PUCCH同传的情况下， 明确 PUSCH的资源映射方 案。

为实现上述目的， 本发明实施例提供如下技术方案： 一种 PUSCH资源 映射的方法， 在配置或调度了 SRS的子帧里， 在同一载波的 PUSCH按照 实际所配置的物理资源进行速率匹配，或者说速率匹配时不扣除 SRS所在 的符号， 不论由于功率受限 SRS不发送还是由于功率不受限 SRS正常发 送， 即不对 SRS所在的符号做速率匹配； 当所述同一载波上有 SRS传输时， 且所述传输的 SRS所在的频带与所述同一载波的 PUSCH资源所在的频带 有部分或全部的重叠时， 对所述同一载波的 PUSCH资源上与 SRS相同符 号的 PUSCH资源进行打孔， 即所述同一载波的 PUSCH不在与 SRS相同的 符号上进行资源映射。
为实现上述目的， 本发明实施例提供如下技术方案： 在配置或调度了 SRS的子帧里， 当在同一载波的 PUSCH上有 UCI传输时， 确定所述 UCI的 调制符号个数时假设 SRS发送或者不发送， 不论由于功率受限 SRS不发送 还是由于功率不受限 SRS正常发送。 为实现上述目的， 本发明实施例提供如下技术方案： 一种 PUSCH资源 映射的装置， 包括： 第一速率匹配单元， 用于当某个子帧存在 SRS和 PUSCH或者 PUCCH同时传输时， 在配置或调度 SRS的子帧里， 在同一载 波的 PUSCH按照实际所配置的物理资源进行速率匹配， 不对 SRS所在的 符号做速率匹配， 或者说速率匹配时不扣除 SRS所在的符号， 不论由于功 率受限 SRS不发送还是由于功率不受限 SRS正常发送； 第一打孔单元， 用 于当所述同一载波上有 SRS传输时， 对所述同一载波的 PUSCH资源上与 SRS相同符号的 PUSCH资源进行打孔。
为实现上述目的， 本发明实施例提供如下技术方案： 一种 PUSCH资源 映射的装置， 包括： 第二速率匹配单元， 用于当某个子帧存在 SRS和 PUSCH/PUCCH同传时， 在配置或调度了 SRS的子帧里， 在同一载波的 PUSCH按照实际所配置的物理资源进行速率匹配， 不对 SRS所在的符号 做速率匹配， 或者说速率匹配时不扣除 SRS所在的符号， 不论由于功率受 限 SRS不发送还是由于功率不受限 SRS正常发送； 第二打孔单元， 用于当 所述同一载波上有 SRS传输时， 且所述传输的 SRS所在的频带与所述同一 载波的 PUSCH资源所在的频带有部分或全部的重叠时， 对所述同一载波 的 PUSCH资源上与 SRS相同符号的 PUSCH资源进行打孔。 本发明实施例与现有技术相比，主要区别及其效果在于：能够在支持 SRS 和 PUSCH/PUCCH同传的情况下，明确 PUSCH的速率匹配和资源映射方案， 以及 UCI的调制符号个数， 消除 eNB侧由于不知道上行是否功率受限而导 致的 PUSCH速率匹配和资源误判， 以及 UCI调制符号个数误判。 附图说明
