In some embodiments of the present application, the mapping ruler of the port PT-RS and DMRS port can be pre-defined.It base station can With putting in order according to the determining SRS resource for needing to be indicated to terminal of the mapping ruler, and need to be indicated to terminal DMRS port puts in order, and due to corresponding between SRS resource and DMRS port, and each SRS resource is corresponding with PT-RS Port, therefore the incidence relation between the port PT-RS and DMRS port can be indicated to terminal by above- mentioned information by base station, and And the mapping ruler defined according to the embodiment of the present application, satisfaction setting channel is mapped to the DMRS port of PT-RS port association The SRS resource of quality requirement；Terminal can be according to the mapping ruler, and according to the SRS resource of base station instruction and its puts in order, And DMRS port and its put in order, the determining DMRS port with PT-RS port association, and then the DMRS port is mapped Data Layer where the SRS resource (or the port SRS) arrived, as data Layer used in transmission PT-RS.

Specifically, the mapping ruler between the DMRS port and the port PT-RS, can be with is defined as: a port PT-RS Corresponding one meets the DMRS port that setting index value requires, and the DMRS port maps to satisfaction setting channel quality requirement SRS resource corresponding to the port SRS.

Wherein, optionally, the satisfaction sets the DMRS port of index value requirement as the smallest DMRS port of index value, institute The SRS resource for stating satisfaction setting channel quality requirement is the best SRS resource of channel quality.

For example, base station measures terminal in the SRS that N number of SRS resource is sent, and is therefrom chosen according to measurement result After channel quality preferable s (s is the integer more than or equal to 1) SRS resource, DMRS port is distributed for the s SRS resource (SRS resource and DMRS port correspond), it is then according to the mapping ruler, index value in this s DMRS port is the smallest DMRS port is mapped to the SRS resource that channel quality is best in this s SRS resource, and this corresponding relationship is indicated to terminal. In terminal side, terminal above-mentioned corresponding relationship according to indicated by base station is mapped according to the smallest DMRS port of index value The SRS resource arrived determines that (corresponding relationship between SRS resource and PT-RS, can for the port PT-RS corresponding to the SRS resource To be pre-configured with) it is associated with the smallest DMRS port of the index value, so as on the data Layer where the DMRS port (data Layer where the SRS resource that the data Layer where DMRS port, the i.e. DMRS port are be mapped to), passes through the PT-RS Port sends PT-RS.

It for the s SRS resource by base station based on measurement selection and is the s SRS resource point in the embodiment of the present application The s DMRS port matched, and corresponding relationship between the two notify to terminal, introduces that " SRS resource instruction state is (referred to as Resource instruction state) " and " DMRS port instruction state (abbreviation port instruction state) ".

Wherein, SRS resource instruction state is used to be directed to SRS resource group, indicates the SRS resource that the SRS resource group is included And its it puts in order.For a SRS resource group, a resource instruction state can be only defined (i.e. in the SRS resource group SRS resource only has one kind and puts in order), multiple resource instruction states (SRS resource i.e. in the SRS resource group can also be defined There are many put in order).It include one or more SRS resources in one SRS resource group.SRS resource in one SRS resource group The corresponding port PR-RS is identical, and the port PT-RS corresponding to different SRS resource groups is different.That is, corresponding to The SRS resource of the same port PT-RS can form a SRS resource group.

For example, if the index value for the SRS resource for including in a SRS resource group is respectively as follows: SRS_n0,SRS_n1,…, SRS_ns-1, then the corresponding resource instruction state of the SRS resource group can include:

Resource instruction state n:{ SRS_n0,SRS_n1,…,SRS_ns-1}

Resource instruction state n+1:{ SRS_n1,SRS_n0,…,SRS_ns-1}

DMRS port instruction state is used to for DMRS port group (include one or more DMRS in a DMRS port group Port), indicate the DMRS port and its put in order that the DMRS port group is included.It, can be only for a DMRS port group It defines a port instruction state (DMRS port i.e. in the DMRS port group only has one kind and puts in order), can also define more A port instruction state (there are many put in order the DMRS port i.e. in the DMRS port group).

For example, if the index value for the DMRS port for including in a DMRS port group is respectively as follows: DMRS_0, DMRS_ 1 ..., DMRS_s-1, the then corresponding port instruction state of the DMRS port group can include:

Port instruction state m:{ DMRS_0, DMRS_1 ..., DMRS_s-1 }

Port instruction state m+1:{ DMRS_1, DMRS_0 ..., DMRS_s-1 }

Wherein, m and m+1 indicates the mark or index of port instruction state.
