Further, usually, undesirable receive of terminal device matches each SRS resource in a SRS resource group Different antenna port numbers is set, alternatively, undesirable receive of terminal device matches each SRS resource in a SRS resource group Set different amount of bandwidth.

The antenna port number of Physical Uplink Shared Channel: in codebook-based transmission (including no day selects and has day choosing When), it can be determined according to the SRS antenna port number that indicated SRS resource is configured；In the biography for being not based on code book It, can be according to the number institute of SRS resource in indicated SRS resource group really in defeated (including the choosing of no day and when there is day to select) Fixed, alternatively, determined according to the total number of SRS resource in the SRS resource group of configuration.

Value information: in multi-antenna technology, multiple antennas (logic, physics are ok) is weighted, by this Weight such as embodies energy in part side so that transmission or received signal spatially have certain energy-distributing feature Upward aggregation.By the directive property effect for the signal that this weighed value adjusting reaches, it is referred to as being precoding, wave beam tax Property.

In general, the modes such as pre-coding matrix, precoder can be used in the digital value information that base band is operated To identify.The weight formed by the phase adjustment of the phase shifter connected in physical antenna, it is believed that it is a kind of simulation weight, It is referred to as space propagation filter.In general, digital weight and simulation weight can be used in mixed way, such as first in base band Using digital weight matrix, again the application simulation weight matrix on radio frequency.Therefore, for pre-coding matrix, precoder, space Transmission filter etc., there is no stringent technologies to distinguish.

In addition, this weight is to combine antenna and/or antenna port application in a manner of a kind of function, such as function can To be multiplication, it is meant that weight can be with the signal multiplication on antenna and/or antenna port as a matrix.Specifically such as, when Weight be pre-coding matrix when, can by pre-coding matrix and DMRS antenna port carrying data manifold at multiplication of vectors, Reach and data flow is subjected to precoding, to reduce inter-stream interference, improves the purpose of system gain.Or such as, by adjusting antenna The phase of the phase shifter of connection forms simulation weight to the signal of transmission, and mathematically and one kind carries out on physical antenna The effect of multiplication weighting.

When the precoding matrix information that value information refers to, it is such that terminal device, which obtains the uplink matrix information that prelists, Process: the network equipment is terminal equipment configuration one or more SRS resource, configures corresponding antenna port number for SRS resource, Such as 1,2,4, indicate that the SRS resource is transmitted using how many a antenna ports.Optionally, the antenna port of SRS resource is The corresponding antenna port of antenna port number configured accordingly is chosen since the lowest order for the SRS antenna port that can be chosen, Such as when configuration SRS resource antenna port number be the antenna port lowest order that 4, SRS can choose is 3000, then SRS resource Antenna port is 3000,3001,3002,3003.Optionally, it may include specific SRS antenna in SRS resource configuration information Port information, such as antenna port 3000 and 3003.The network equipment is in Downlink Control Information (downlink control Information, DCI) in indicate SRS resource, terminal device indicates according to SRS resource, obtains indicated SRS resource SRS antenna port number determines the antenna port number of PUSCH.In general, in codebook-based transmission, the day of PUSCH Line port number is equal to the SRS antenna port number of indicated SRS resource.Antenna port number and precoding indicate information field With corresponding relationship.Terminal device indicates information field (precoding according to the precoding in antenna port number and DCI Information and number of layers) determine indicated pre-coding matrix.Specifically include terminal device root It determines which table searched according to port number, indicates that the value determination of information field is with which of table according to the precoding of DCI Pre-coding matrix (index), so that it is determined that corresponding pre-coding matrix.Also, it is further indicated in precoding square instruction information field The order of uplink.The order of uplink embodies the number of the independent data flow of upstream data, related with the Antenna Correlation of channel, letter The Antenna Correlation in road is higher, and order is smaller, conversely, the Antenna Correlation of channel is lower, order is higher.

Further, the precoding in DCI indicates information field (precoding information and number of Layers) it is used to indicate the transport layer (namely order) of precoding matrix information and uplink.

When the precoder or space propagation filter etc. that value information refers to, terminal device acquisition is such mistake Journey: terminal device can send at least one SRS resource according to the configuration of the network equipment, and one of SRS resource has corresponded to one A value information (has corresponding relationship) i.e. between SRS resource and value information, each SRS resource can be comprising 1 SRS days Line end mouth, and transmission SRS resource is carried out using this value information.After the network equipment receives at least one SRS resource, net Network equipment can measure, and the network equipment is that terminal device dispatch network equipment thinks preferable SRS resource, and the network equipment refers to Show and indicate that information, the instruction information can be carried by high-level signaling or physical layer signaling to terminal device SRS resource, such as It is carried by DCI.Terminal device is indicated according to the SRS resource that the network equipment indicates, is believed using the corresponding weight of the SRS resource Breath, the operation of (precoding in other words, beam forming etc.) is weighted to PUSCH.

The relationship of value information and logical antenna, physical antenna: on different physical antennas, identical patrol can be corresponded to Antenna is collected, but the channel of these different physical antennas may be different, therefore the suitable weight letter that the network equipment is measured Breath may be different.Accordingly, it is believed that the transmission of value information indicated by the network equipment and network equipment instruction terminal equipment Antenna has corresponding relationship.Often the network equipment is based on uplink detection signal channel experienced, can measure and determines uplink The corresponding value information of data, and it is variant by the channel of the uplink detection signal of different antenna transmissions, therefore network is set Standby corresponding different physical antenna, which may measure, determines different value informations.And value information, as pre-coding matrix is logical It is often to be weighted to logical antenna.Precoder, space propagation filter etc. be to antenna, and/or, logical antenna carry out Weighting.

The purposes of SRS resource (group): the purposes of SRS resource (group) has corresponding pass with the transmission characteristic etc. of SRS resource (group) System.As being to carry out wave beam management when being configured to purposes, then at least two resources in the SRS resource group can be different with correspondence Send wave beam (namely different space propagation filters) or (the namely different reception space filter of different reception wave beams Wave, or the non-standard of reception are co-located)；When configuring purposes is that SRS antenna switches, then at least two resources in the SRS resource group exist Transmission is switched on different antennas.
