(PUSCH);
Alternatively, UE, which sends up PUCCH/PUSCH/SRS information, can use different send-receive wave beams pair, such as:
PUSCH using optimal send-receive wave beam to 1 and Timing Advance TA1, PUCCH using suboptimum send-receive wave beam to 2 and
Timing Advance TA2, then to avoid the cover jamming of up different beams propagation delay time, it is necessary to meet:| TA1-TA2 | < CP;
Otherwise, UE needs to retransmit PUSCH information every an OFDM symbol after PUCCH is sent.
Above-mentioned embodiment illustrated in fig. 11 is only explained with 4 UE of scheduling simultaneously, while UE numbers, UE and the base station beam dispatched
Combined situation, it is easy to be generalized to while dispatch any scene of other combinations of more than 4 UE, UE and base station beam.
