It is accurate co-located, it is right for indicating that there are one or more identical or similar communication features between multiple resources In multiple resources with apposition, same or similar communication configuration may be used.For example, if two antenna ports With apposition, then the channel large scale characteristic that a port transmits a symbol can transmit one from another port The channel large scale characteristic of symbol is inferred to.Wherein, large scale characteristic may include：Delay extension, average retardation, Doppler Extension, Doppler frequency shift, average gain, terminal device receive wave beam number, and transmitting/reception channel relevancy receives angle of arrival, The spatial coherence etc. of receiver antenna.

Based on this, the resource of other signals sent on the wave beam for sending PDCCH can be used to indicate the wave beam.It can Choosing, which can be reference signal, such as CSI-RS.Wherein, " resource " here can include but is not limited to following letter At least one of breath：Running time-frequency resource, port number, period, offset etc..

It should be understood that if base station sends PDCCH using some wave beam to UE, base station is sent out using this wave beam Pass through CSI-RS.This is because general base station needs first to send CSI-RS to UE, to carry out channel measurement；Then, letter is recycled Road measurement result sends PDCCH to UE.If based on this it is found that base station to UE be notified of port numbers that CSI-RS is used and/or Resource number, UE would know that base station sends PDCCH using which or which wave beam.

As shown in figure 9d, it is a kind of correspondence between CSI-RS resource and wave beam.

Optionally, CSI-RS resource number can be resource ID, alternatively, (the ports resource ID+port ID ID).In this case, it is assumed that beam_idxWherein, each number indicates a CSI-RS resource for={ 0,1 ..., }, then, Offset and a kind of possible relevant way of CSI-RS resource are：Offset=beam_idxMod N, wherein N is one pre- Definition or configurable integer.

For example, as shown in figure 9d, if used CSI-RS resource number is #0 and #1 when base station is to UE transmission CSI-RS, and And send PDCCH, and N=2 to the UE using the wave beam for sending CSI-RS, then offset=0 can be used to obtain CSI-RS and provided Source number is the scramble sequence of the corresponding wave beams of #0, and it is the corresponding wave beams of #1 to obtain CSI-RS resource number using offset=1 Scramble sequence.

Mode 6：Wave beam instruction information is wave beam to connection (beam pair link, BPL) information.

BPL information can be BPL numbers etc..Assuming that beam_idxWherein, each number indicates one for={ 0,1 ..., } BPL, as shown in figure 9e.So, offset and a kind of possible relevant way of BPL information are offset=beam_idx.For example, As shown in figure 9e, base station sends PDCCH using wave beam pair 0 and wave beam pair 1 to UE, it is possible to obtain wave using offset=0 0 corresponding scramble sequence of beam obtains 1 corresponding scramble sequence of wave beam using offset=1.

Mode 7：Wave beam indicates that information is UE groups.Wherein, the UE in a beam coverage constitutes a UE group, each UE groups may include one or more UE, and a UE may belong to one or more UE groups.

As shown in figure 9f, 1 corresponding UE groups 1 of wave beam include UE1, and 2 corresponding UE groups 2 of wave beam include UE1 and UE2, 3 corresponding UE groups 3 of wave beam include UE2.In this case, it is assumed that beam_idxWherein, each number refers to a UE to={ 0,1 .., } Group, then, a kind of possible relevant way of offset and UE groups is：Offset=beam_idx.For example, as shown in figure 9f, base Standing can use offset=1 to obtain 1 corresponding scramble sequence of wave beam, and 2 corresponding scrambling sequence of wave beam is obtained using offset=2 Row obtain 3 corresponding scramble sequence of wave beam using offset=3.

Mode 8：Wave beam indicates that information is time-domain symbol.

The time-domain symbol refers to sending the OFDM symbol occupied when the wave beam.Which is suitable for base station and uses multiple wave beams PDCCH is sent to the same UE on different symbols, and a wave beam is only used to the field of UE transmission PDCCH in each symbol Jing Zhong.As shown in figure 9g, base station sends PDCCH using a wave beam in symbol 0 to UE, and uses another wave beam in symbol 1 PDCCH is sent to the UE.

Assuming that beam_idxWherein, each number refers to a symbol time for={ 0,1 ..., }.So, offset is accorded with time domain Number a kind of possible relevant way be：Wherein, N is one predefined or configurable Integer, such as N=9.
