Abstract
The embodiments of the present invention relate to the field of wireless communications. Disclosed are a resource mapping method and device for a PUSCH. When SRS and PUSCH or PUCCH simultaneous transmission exists in a certain subframe, in a subframe in which the SRS is configured or scheduled, physical resource mapping is performed on a PUSCH of the same carrier according to an actually configured physical resource, and rate matching is not performed on a symbol where the SRS is located; and when an SRS is transmitted on the same carrier, a PUSCH resource with the same symbol as the SRS on the PUSCH resource of the same carrier is punctured. The method provided above can, in the case of supporting SRS and PUSCH/PUCCH simultaneous transmission, define a resource mapping solution for a PUSCH, and eliminate misjudgments in PUSCH resources caused by the fact that an eNB side does not know whether the uplink is in power limitation.
Description
A kind of PUSCH method for mapping resource, the present invention relates to wireless communication field, more particularly to a kind of PUSCH method for mapping resource and device for engineering device technique field.Background technology
In existing 3GPP E-UTRA systems, under state of carrier aggregation, SRS and PUSCH (hysical downlink data share channel, physical down Data Shared Channel)/PUCCH channels are not supported（Physical downlink control channel, Physical Downlink Control Channel）It is transmitted at the same moment.If the PUSCH of the SRS of some carrier wave and other carrier waves is appeared in the last symbol of a subframe simultaneously, then UE does not send SRS, PUSCH on this carrier wave is mapped on the whole RE distributed, it is not necessary to do rate matching (rate-matcheds）, as shown in Figure 1.In same carrier wave, if UE has SRS transmission in the last symbol of some subframe, and have PUSCH transmission in the subframe, so PUSCH is sent not in last symbol, i.e. PUSCH is mapped on the preceding n-1 symbol of n symbol of the subframe after carrying out rate-matched according to n-1 symbol.Or in same carrier wave, if being configured with the SRS bandwidth of cell-level in the last symbol of some subframe, PUSCH part or all of and bandwidth overlays on frequency domain, then PUSCH is mapped on n symbol symbol of the subframe after carrying out rate-matched according to n symbol.Because whether the eNB SRS that know for sure send, therefore which kind of mode rate-matched is carried out in the absence of ambiguity issue according to for PUSCH.But in LTE Rel-11 versions, if UE is configured for multiple TAG (time advanced group), the simultaneous interpretation of SRS and PUSCH/PUCCH on different carrier waves can then be supported, only when SRS and PUSCH/PUCCH power sum exceedes the upper limit of the power set in advance, SRS is not just sent.Such case result in UE and send SRS sometimes, sometimes because power limited is without sending out SRS, due to eNB be not aware that UE whether power limited, according to existing protocol, it can cause eNB can not clearly and the PUSCH that pass in same carrier wave of SRS carry out rate adaptation operatings according to how many symbols.
The content of the invention
