Detailed Description
In order to solve the above problems in the prior art, in the technical scheme adopted in the embodiments of the present invention, the user equipment divides the first type of radio resources into the first radio resources and the second radio resources according to whether the user equipment overlaps with the second type of radio resources allocated to other user equipment by the network side, and performs different transmission processing on the data transmitted by using the first radio resources and the data transmitted by using the second radio resources, so that the network side can distinguish the data transmitted by different user equipment on the first radio resources, and the reliability of uplink data transmission can be improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 shows a flow chart of a speech recognition method in an embodiment of the invention. The speech recognition method as shown in fig. 1 may include the steps of:
step S101: and according to the acquired information of the first type wireless resources allocated to the network side and the second type wireless resources allocated to other equipment by the network side.
In a specific implementation, when the ue sends data to the network side, it needs to first obtain the uplink radio resource allocated by the network side for the ue, and then send the data to the network side by using the uplink radio resource allocated by the network side.
In a general situation, the requirement on the real-time performance of uplink data sent by the user equipment is not high, and in the present application, such uplink data with low real-time performance is referred to as high-delay uplink data. In some low-delay and high-reliability communication scenarios, the requirement on the real-time performance of uplink data sent by user equipment is high, and the uplink data is referred to as low-delay uplink data in the present application.
Accordingly, the uplink radio resource formed by the time domain and the frequency domain on the air interface may be divided into a first type radio resource and a second type radio resource. The first type of wireless resource is a physical resource which is allocated to a user equipment (first user equipment) by a network side to transmit high-delay uplink data, and the second type of resource is a physical resource which is allocated to other user equipment (second user equipment) by the network side to transmit low-delay uplink data.
Referring to fig. 2, a radio resource of one subframe in LTE is taken as an example, and includes two subframes, each subframe includes 7 consecutive slots on the horizontal axis and 12 consecutive subcarriers on the vertical axis. Wherein, the network side has allocated the radio resource of one subframe shown in fig. 2 as the first type radio resource to the first user equipment. However, in order to meet the requirement of low-latency high-reliability communication of other user equipments, the network side may occupy part of the first type of radio resources already allocated to the first user equipment and simultaneously allocate to the second user equipment to transmit the low-latency uplink data, that is, the second type of radio resources partially or completely overlap with the first radio resources.
Fig. 2 shows a case where the first type radio resource and the second type radio resource allocated to the first user equipment occupy only 12 subcarriers of one resource block in the frequency domain. In practice, the situation of the subcarriers occupied by the first type radio resources and the second type radio resources in the frequency domain may also include subcarriers corresponding to a plurality of resource blocks.
For example, fig. 3 shows a case where the number of subcarriers occupied by the second type radio resource allocated to the second user equipment in the frequency domain is equal to the number of subcarriers occupied by the first type radio resource. Fig. 4 shows a case where the number of subcarriers occupied by the second type radio resource allocated to the second user equipment is greater in the frequency domain than the number of subcarriers occupied by the first type radio resource. Wherein the RB represents a first type radio resource and the URB represents a second type radio resource.
Of course, in the specific implementation, the first type radio resource and the second type radio resource in the embodiment of the present invention are not limited to the above, and the network side may allocate the first type radio resource and the second type radio resource to the user equipment according to actual needs.
For example, the first type of radio resource includes one or more first radio resource blocks, and the first radio resource blocks may include radio resources of a plurality of time domain units and one frequency domain unit; the second type of radio resource includes at least one second radio resource block, which may include radio resources of a plurality of frequency domain units and one time domain unit. One time domain unit may include one slot, one subframe, or one symbol, or may also include multiple slots, multiple subframes, or multiple symbols. One frequency domain unit may include one subcarrier or a plurality of subcarriers.
In a specific implementation, after allocating the first type radio resource to the first user equipment, the network side sends information of the allocated first type radio resource to the first user equipment. Meanwhile, when the second user equipment needs to occupy part of uplink wireless resources allocated to the first user equipment for uplink transmission of low-delay data, the network side sends information of the second type of wireless resources allocated to the second user equipment to the first user equipment.
Step S102: and dividing the first type of wireless resources into first wireless resources and second wireless resources, wherein the first wireless resources are overlapped with the second type of wireless resources, and the second wireless resources are not overlapped with the second type of wireless resources.
In a specific implementation, after the first user equipment acquires information of a first type of radio resource allocated to the first user equipment and a second type of radio resource allocated to the second user equipment by the network side, the first user equipment may divide the first type of radio resource allocated to the first user equipment by the network side into a first radio resource overlapping with the second radio resource and a second radio resource not overlapping with the second type of radio resource.
Step S103: and performing corresponding transmission processing on the data sent by using the first wireless resource and the data sent by using the second wireless resource respectively to obtain corresponding first transmission data and second transmission data.
In a specific implementation, the first radio resource overlaps with the second type of resource, which means that when the first user equipment uses the first radio resource to perform uplink data transmission, the second user equipment may also use the first radio resource to transmit uplink data, but the first user equipment and the second user equipment cannot know whether the other party uses the first radio resource to perform uplink data transmission at the same time. Therefore, there will be interference between the uplink data transmitted by the first user equipment using the first radio resource and the uplink data transmitted by the second user equipment using the first radio resource, so that the base station cannot correctly receive the corresponding uplink data.
Therefore, in order to avoid interference caused by the shared uplink radio resource, when the first user equipment uses the uplink data transmitted by the first radio resource, the first user equipment may use different transmission processing for the uplink data transmitted by the second radio resource that does not overlap with the second type radio resource.
For example, the order of the modulation scheme used for the uplink data transmitted using the first radio resource is lower than the order of the modulation scheme used for the uplink data transmitted using the second radio resource. For example, when the transport block transmitted by the second radio resource adopts a 64QAM modulation scheme, the transport block transmitted by the first radio resource can adopt a 16QAM or QPSK modulation scheme; for another example, the transmission power used for transmitting the uplink data by using the first radio resource is less than the transmission power of the uplink data transmitted by using the second radio resource.
Meanwhile, in order to further improve the reliability of the uplink data, the first user equipment may use the first radio resource to transmit some relatively unimportant data when performing the transmission of the uplink data.
For example, in the physical resource mapping, the check bits of the channel coding are mapped onto the first radio resource for transmission, for example, the Turbo coding rate is one third, one third of which is the original information bits, and the remaining two thirds are the check bits. In an embodiment of the present invention, the original information bits may be transmitted using the second radio resource, and the check bits may be transmitted using the first radio resource. For another example, in physical channel mapping, repeated bits in rate matching may be mapped to the first radio resource, and original bits may be mapped to the second radio resource.
Step S104: the obtained first transmission data is transmitted using the first radio resource, and the obtained second transmission data is transmitted using the second radio resource.
In a specific implementation, after different transmission processes are performed on a block to be transmitted to obtain first transmission data and second transmission data, the first transmission data may be sent to a corresponding base station by using the first radio resource, and the obtained second transmission data may be sent to the corresponding base station by using the second radio resource.
The corresponding apparatus of the above method will be described in further detail below.
