Problems solved by technology

When uplink control information (UCI) is to be transmitted on one of the K PUSCHs, and the number of physical resources of this PUSCH is small, the physical resources occupied by the UCI calculated using the above TBS are too large, resulting in This PUSCH is overloaded, which reduces the reliability of information transmission

Embodiment Construction

[0066] The embodiment of the invention discloses a communication method and equipment, which are used to improve the reliability of information transmission. Each will be described in detail below.

[0067] In order to better understand the communication method and device disclosed in the embodiment of the present invention, the network architecture used in the embodiment of the present invention will be described below first. see figure 1 , figure 1 It is a schematic diagram of a network architecture disclosed by an embodiment of the present invention. Such as figure 1 As shown, the network architecture may include one or more terminal devices 101 ( figure 1 6) and network device 102 are shown in the figure. figure 1 The network device 102 and the six terminal devices 101 (ie, terminal devices 1-6) can form a communication system, and the terminal devices 4-6 can also form a communication system.

[0068] The communication between the terminal device 101 and the network...

Abstract

The embodiment of the present invention discloses a communication method and equipment, including: the terminal equipment receives the information of K uplink data channels for K repeated transmission of data packets from the network equipment and the information for transmitting the first uplink control information UCI After the information of the first time-domain resource, if the first time-domain resource overlaps with the first uplink data channel in the K uplink data channel in the time domain, and the first uplink data channel is overloaded, it is determined to be used for transmission the physical resource of the first UCI, and then send the first UCI to the network device through the determined physical resource. In the embodiment of the present invention, when resources for transmitting UCI and data packets overlap and are overloaded in the time domain, the physical resources occupied by UCI can be determined, so as to ensure the transmission reliability of UCI, thereby improving the reliability of information transmission.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a communication method and device. Background technique [0002] In order to enhance the reliability of data transmission, a multiple repeated transmission mechanism is introduced in 5G new air interface (new radio, NR), that is, a data packet is repeatedly transmitted K on physical uplink shared channel (PUSCH). Second-rate. Since the K PUSCHs are used to repeatedly transmit the same data packet, the transport block size (transport block size, TBS) needs to be kept the same. In the case that K PUSCHs include the same number of physical resources, the TBS may be calculated based on the number of physical resources of the first PUSCH among the K PUSCHs. When uplink control information (UCI) is to be transmitted on one of the K PUSCHs, and the number of physical resources of this PUSCH is small, the physical resources occupied by the UCI calcul...
