Problems solved by technology

For different TP / RPs, for example, TP / RP102, 103 and 104, they cannot have different TDD UL / DL configurations so that they cannot adapt to their own uplink / downlink traffic respectively

[0046] figure 2 is a diagram illustrating a wireless communication method by a base station according to an embodiment of the first embodiment. image 3 is a diagram illustrating a wireless communication method by a user equipment (UE) according to another embodiment of the first embodiment.

[0047] In the first embodiment, on the side of a (macro) base station, a wireless communication method is provided in which a base station transmits uplink / downlink (UL / DL) configurations in a common search space of a wireless communication system. Such as figure 2 As shown, the method includes step 201: sending the UL / DL configuration to the UE under coverage in the common search space, wherein the UL of the UE connected to a specific TP / RP is identified by a bit in the downlink control information (DCI) / DL configuration.

[0048] It should be noted that although figure 2 The wireless communication method by (macro) base station is explained, but since the macro base station sha...

[0067] Figure 4 It is a diagram showing a wireless communication method by a base station according to an embodiment of the second embodiment. Figure 5 is a diagram illustrating a wireless communication method by a user equipment (UE) according to another embodiment of the second embodiment.

[0068] In the second embodiment, at the (macro) base station or TP / RP side, such as Figure 4 As shown, the method includes step 401: sending UL / DL configurations to UEs under coverage in a UE group common search space (UE group CSS). Correspondingly, on the UE side, such as Figure 5 As shown, the method includes step 501: receiving UL / DL configuration in UE group common search space.

[0069] Specifically, in this embodiment, UEs in a wireless communication system are grouped, eg, based on different TP / RPs to which the UEs are connected. That is, UEs in a certain group can be connected to the same TP / RP, or connected to different TP / RPs. It should be noted that when UEs in a cer...

[0075] Figure 6 It is a diagram showing a wireless communication method by a base station according to an embodiment of the third embodiment. Figure 7 is a diagram illustrating a wireless communication method by a UE according to another embodiment of the third embodiment. Similar to the case in the first embodiment, the wireless communication method is also applied to a wireless communication system including a plurality of TP / RPs.

[0076] On the (macro) base station side, in the wireless communication method according to the third embodiment, as Figure 6 As shown, the method includes step 601: sending UL / DL configurations to UEs connected to a specific TP / RP in a common search space (CSS) of specific time / frequency resources associated with the specific TP / RP.

[0077] Also, despite Figure 6 Not shown in , but at the TP / RP side, similarly, the method includes the steps of: sending the UL / DL configuration to the TP / RP connected to the TP / RP in a common search space of...

Abstract

The present disclosure provides a wireless communication method, a transmission / reception point, a user equipment and a wireless communication system, the wireless communication method comprising a step of: receiving the UL / DL configuration for the UE in a common search space of a specific time / frequency resource associated with a specific TP / RP, wherein, the UE is attached to the specific TP / RP, and the association between a number index of the specific TP / RP and an index of the specific time / frequency resource is predefined.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a wireless communication method, a base station, a sending point / receiving point, user equipment and a wireless communication system. Background technique [0002] eIMTA (further enhancements to Long Term Evolution (LTE) Time Division Duplex (TDD) for downlink-uplink (DL-UL) interference management and traffic adaptation) is a work item (WI) subject in 3GPP LTE Release 12 and To adapt to the business by modifying the TDD UL / DL configuration. One of the main focuses is to enable fast TDD UL / DL configuration for traffic adaptation. Currently, TDD UL / DL configuration information is carried in System Information Block 1 (SIB1) and the change period is 640ms. One of the discussion points is how to send TDD UL / DL configuration information in the physical layer (L1). [0003] So far there are generally four options regarding fast TDD UL / DL configuration signaling: (1) implicit sign...
