Technical Field

The present application relates to transmission methods and apparatus in wireless communication systems, and more particularly to communication methods and apparatus supporting data transmission over unlicensed spectrum (Unlicensed Spectrum).

Background

In conventional 3GPP (3 rd Generation Partner Project, third generation partnership project) LTE (Long-term Evolution) systems, data transmission can only occur on licensed spectrum, however, with a drastic increase in traffic, especially in some urban areas, the licensed spectrum may be difficult to meet the traffic demand. Communications on unlicensed spectrum in Release 13 and Release 14 are introduced by the cellular system and used for transmission of downlink and uplink data. To ensure compatibility with access technologies on other unlicensed spectrum, LBT (Listen Before Talk ) technology is adopted by LAA (Licensed Assisted Access, licensed spectrum assisted access) to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources.

In the conventional LTE system, the uplink transmission is often based on Grant (Grant) of the base station, and in Phase (version) 1 of 5G NR (New Radio Access Technology ), the terminal may perform Grant-Free uplink transmission in an air interface resource preconfigured by the base station on the Grant spectrum, so as to reduce overhead of air interface signaling and improve spectrum efficiency of the system. Currently, 5G NR is under discussion about access technologies for unlicensed spectrum, where grant-free uplink transmission on unlicensed spectrum needs to be reconsidered.

Disclosure of Invention

The inventor finds that how to increase the utilization rate of air interface resources as much as possible in an NR system, and improving the system capacity is a key problem to consider.

In view of the above, the present application discloses a solution. It should be noted that the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other without collision.

The application discloses a method used in first user equipment of wireless communication, which is characterized by comprising the following steps:

receiving first information, wherein the first information is used for determining first time-frequency resources reserved for a first wireless signal;

monitoring whether the first downlink wireless signal is transmitted on a reference time-frequency resource;

the first downlink wireless signal is not transmitted on the reference time-frequency resource, and the first wireless signal is transmitted on the first time-frequency resource; or, the first downlink wireless signal is transmitted on the reference time-frequency resource, and the transmission of the first wireless signal on the first time-frequency resource is abandoned;

wherein the first reference access detection performed is used to determine whether to transmit the first downlink wireless signal on the reference time-frequency resource, the end time of the first reference access detection preceding the start time of the reference time-frequency resource; the ending time of the reference time-frequency resource precedes the starting time of the first time-frequency resource.

As an embodiment, the problem to be solved by the present application is: the existing NR Phase 1 version supports grant-free uplink transmission on a licensed spectrum, a base station allocates an air interface resource pool to a ue performing grant-free transmission in advance, and then the ue sends uplink data in the allocated air interface resource pool by itself. For grant-free uplink transmission on unlicensed spectrum, the pre-allocated air interface resource pool may not be occupied, which may cause resource waste and affect system capacity. How to fully utilize the air interface resource pool is a key problem to be solved.

As an embodiment, the essence of the method is that in the present application, the first ue is a Grant-based user, the second ue is a Grant-Free user, the second time-frequency resource is a time-frequency resource pre-allocated by the base station for Grant-Free uplink transmission of the second ue, the transmission beam of the first downlink radio signal is the same as the reception beam of the base station in the second time-frequency resource, the first time-frequency resource is a time-frequency resource allocated by the base station for Grant uplink transmission of the first ue, and the first time-frequency resource and the second time-frequency resource overlap (are not orthogonal) partially; if the base station cannot send the first downlink wireless signal because the LBT does not pass, the second user equipment does not perform grant-free uplink transmission on the second time-frequency resource, and the first user equipment can send grant-based uplink transmission on the first time-frequency resource; conversely, if the base station transmits the first downlink radio signal because of LBT, the second ue may perform grant-free uplink transmission on the second time-frequency resource, and the first ue may not transmit grant-based uplink transmission on the first time-frequency resource. The method has the advantages that on one hand, the base station LBT does not indicate that uplink interference is strong, the base station does not expect to receive uplink wireless signals in the LBT beam direction, and the second user equipment can determine whether uplink transmission is performed by detecting whether the first downlink wireless signals are sent or not; on the other hand, the time-frequency resource pre-allocated for grant-free uplink transmission can be used for grant-based uplink transmission under the condition of not being occupied by grant-free users, so that the utilization rate of air interface resources is improved, and the system capacity is improved.

The method has the advantages that the grant-free user judges whether the grant-free uplink transmission can be carried out on the corresponding air interface resource according to the downlink signal measurement, the indication signaling overhead of the base station is saved, and the increase of the user complexity and the increase of the power consumption caused by monitoring the indication signaling are avoided.

Fig. 4 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, fig. 4 shows the radio protocol architecture for a User Equipment (UE) and a base station device (gNB or eNB) in three layers: layer 1, layer 2 and layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY301. In the user plane, the L2 layer 305 includes a MAC (MediumAccess Control ) sublayer 302, an RLC (Radio Link Control, radio link layer control protocol) sublayer 303, and a PDCP (Packet Data Convergence Protocol ) sublayer 304, which terminate at the gNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., remote UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out of order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but there is no header compression function for the control plane. The control plane also includes an RRC (RadioResource Control ) sublayer 306 in layer 3 (L3 layer).
