Embodiment 1
[0106] Embodiment 1 illustrates the flow chart of sending signaling on the LAA carrier, as shown in the attached figure 1 shown. attached figure 1 In , the serving cell of UE U2 is maintained by base station N1, the steps identified in block F1 are optional.
[0107] For the base station N1, the first high layer signaling is sent in step S11, the first signaling is sent in step S13, and the second signaling is received on the first carrier in step S14.
[0108] For the UE U2, the first high layer signaling is received in step S21, the first signaling is received in step S13, and the second signaling is sent on the first carrier in step S14.
[0109] In Embodiment 1, the first high layer signaling indicates L candidate carriers. The first signaling includes the index of the first carrier, or the first signaling is transmitted on the first carrier. The first signaling is physical layer signaling, and the second signaling includes at least one of {scheduling request, K1 CSI g...
Embodiment 2
[0118] Embodiment 2 illustrates a schematic diagram of dynamic switching of physical layer control channels on multiple carriers, as shown in the attached figure 2 shown. attached figure 2 In , the thick line box identifies the time-frequency resource occupied by the physical layer control channel.
[0119] The L candidate carriers in the present invention are as attached figure 2 In the carrier {#1, #2, ..., #L} shown.
[0120] as attached figure 2 As shown, the physical layer control channel in the present invention is dynamically configured by the base station on carriers {#1, #2, ..., #L}.
[0121] As sub-embodiment 1 of embodiment 2, the physical layer control channel is PUCCH.
[0122] As a sub-embodiment 2 of Embodiment 2, if the physical layer control channel occupies time-frequency resources on the unlicensed spectrum, the UE can send an uplink signal on the physical layer control channel without LBT operation.
Embodiment 3
[0124] Embodiment 3 illustrates the schematic diagrams of the first moment and the second moment, as attached image 3 shown. attached image 3 , the squares with bold lines indicate the time-frequency resources occupied by uplink bursts, and the squares with slashes indicate the time-frequency resources occupied by downlink bursts.
[0125] In Embodiment 3, the first signaling is transmitted on the first carrier and the time interval between the first moment and the second moment is smaller than a specific threshold, and the UE can send the second signaling without performing LBT. The first moment is the end moment of the downlink burst corresponding to the first signaling, and the second moment is the start moment of the uplink burst corresponding to the second signaling.
[0126] As a sub-embodiment 1 of Embodiment 3, the first signaling is a signature sequence, and the signature sequence includes at least one of {Zadoff-Chu sequence, pseudo-random sequence}. As an embod...
