Technical Field

The present application relates to a method and apparatus for transmitting a radio signal in a radio communication system, and more particularly, to a method and apparatus for transmitting a radio signal in a radio communication system supporting a cellular network.

Background

In conventional 3GPP (3 rd generation partnerproject) LTE (Long-term evolution) systems, data transmission can only occur on licensed spectrum, but with a drastic increase in traffic, especially in some urban areas, licensed spectrum may be difficult to meet the traffic demand. Communications on unlicensed spectrum in Release13 and Release14 are introduced by the cellular system and used for transmission of downlink and uplink data. To ensure compatibility with other access technologies on unlicensed spectrum, LBT (listen before talk) technology is adopted by LAA (licensed assisted access) to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources. The transmitter of the LTE system adopts a quasi-omni antenna to perform LBT.

Currently, a technical discussion of 5GNR (new radio access technology) is in progress, wherein Massive (Massive) MIMO (Multi-input Multi-Output) is one research hotspot of next generation mobile communication. In massive MIMO, a plurality of antennas form beams directed to a specific spatial direction by Beamforming (Beamforming) to improve communication quality, and when considering coverage characteristics due to Beamforming, conventional LAA techniques need to be reconsidered, such as LBT schemes.

Disclosure of Invention

The inventor finds that in the 5G system, the beamforming will be used in a large scale, and the LBT scheme based on the beamforming will have an effect on the transmission of the uplink wireless signal. The transmission of uplink radio signals for multiple beams may require a process of using multiple LBTs based on beamforming, and the multiple LBTs may generate that only part of the uplink radio signals on multiple beams may be transmitted, so a transmission scheme of multi-beam uplink radio signals under multiple LBTs is a key problem to be solved.

In view of the above, the present application discloses a solution. It should be noted that, without collision, the embodiments in the UE (user equipment) and the features in the embodiments of the present application may be applied to the base station, and vice versa. Further, the embodiments of the present application and features in the embodiments may be arbitrarily combined with each other without collision.

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

receiving first information, the first information being used to determine N multicarrier symbols over a first subband, the N being a positive integer greater than 1;

Performing a first access detection, determining M multi-carrier symbols of the N multi-carrier symbols;

for the N multi-carrier symbols on the first sub-frequency band, respectively transmitting M reference signals in the M multi-carrier symbols;

wherein the M reference signals are used to determine the M multicarrier symbols from the N multicarrier symbols, the N multicarrier symbols are allocated to N1 antenna port groups, the M reference signals are transmitted by U1 antenna port groups of the N1 antenna port groups, M is a positive integer not greater than the N, U1 is a positive integer not greater than the M, and N1 is a positive integer not greater than the N.

As an embodiment, the essence of the method is that the first access detection corresponds to one or more LBTs based on beamforming, and different LBTs may monitor with different beams, where the beams of the one or more LBTs correspond to multiple beams of uplink reference signals that the base station desires to send on N multi-carrier symbols, respectively; after LBT of a certain beam passes, user equipment can send uplink reference signals on a multi-carrier symbol corresponding to the beam; if the LBT of a certain beam does not pass, the ue may not transmit an uplink reference signal on the multicarrier symbol corresponding to the beam. The method has the advantages that the user equipment can send the reference signal on the channel which is not occupied by a certain wave beam according to the channel occupation condition on different actual wave beams through the corresponding relation between the reference signal and the LBT, and interference caused by that a plurality of transmitters occupy the same frequency resource at the same time is avoided.

According to one aspect of the present application, the method is characterized by comprising:

respectively transmitting M1 reference signals in M1 multi-carrier symbols on the first sub-frequency band;

wherein the transmission power of any one of the M1 reference signals is the same as the transmission power of any one of the M reference signals, at least one multicarrier symbol not occupied by the user equipment exists, and the multicarrier symbol not occupied by the user equipment precedes the M1 multicarrier symbols and follows the M multicarrier symbols.

As an embodiment, the essence of the above method is that the transmission of M reference signals and M1 reference signals is a transmission after LBT on two different beams, respectively; since the beam direction of the uplink reference signal corresponding to the same LBT is limited within the beam corresponding to the LBT, in order for the base station to know whether there is a better beam in the beam direction outside the beam of the LBT, it is necessary to perform fair comparison on the multiple reference signal transmissions corresponding to the multiple LBT beams, so that the user equipment needs to use the same transmission power when transmitting the multiple reference signals. The advantage of using the above method is that the same transmit power is used for a plurality of reference signals corresponding to a plurality of LBT beams for fair channel/beam quality comparison.

The method has the advantage that the rest of the M reference signals can be further detected by blindly detecting one or more of the M reference signals, so that the base station can know which reference signals have no transmission beams passing through the uplink LBT.

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.
