Embodiment 1

[0156] In this embodiment, the system bandwidth is divided into multiple first resource sets, and the first resource set is composed of multiple RBs evenly distributed on the entire system bandwidth. Optionally, the first resource set may adopt an interlace structure as in eLAA. When performing resource allocation, the network device adopts a part of continuous RBs in the first resource set as the second resource set. In other words, the resource block of the second resource set allocated by the network device to the terminal is composed of an integer number of consecutive resource blocks in the first resource set.

[0157] Then, the network device may send resource scheduling information and frequency hopping information to the terminal, where the resource scheduling information is used to indicate the second resource set allocated by the network device to the terminal, and the frequency hopping information is used to indicate the frequency hopping mode associated with the secon...

Embodiment 2

[0188] The difference from the first embodiment is that the network device uses some non-contiguous RBs in the first resource set as the basic scheduling unit. In other words, the second resource set allocated by the network device to the terminal is composed of an integer number of non-contiguous resource blocks in the first resource set.

[0189] Specifically, the second set of resources allocated by the network device to the terminal may be expressed as: RB START +l+i·N, where RB START Represents the index of the starting resource block allocated to the terminal; l∈L, the set L includes the index of the first resource set to which the second resource set belongs; N represents the distance between two adjacent RBs in the first resource set ; I ∈ M, the set M includes the index of the resource block in the second resource set in the first resource set to which the second resource set belongs.

[0190] Specifically, during frequency hopping, the second set of resources allocated ...

Embodiment 3

[0219] In this embodiment, the system bandwidth is divided into multiple first resource sets, and the first resource set is composed of multiple RBs evenly distributed on the entire system bandwidth. Optionally, the first resource set may adopt an interlace structure as in eLAA. When performing resource allocation, the network device uses part of the RBs in the multiple first resource sets as the basic scheduling unit. In other words, the second resource set allocated to the terminal by the network device is composed of an integer number of resource blocks in at least two first resource sets.

[0220] Specifically, the second set of resources allocated by the network device to the terminal may be expressed as: RB START +l+i·N, where RB START Represents the index of the starting resource block allocated to the terminal; l∈L, the set L includes the index of the first resource set to which the second resource set belongs; N represents the distance between two adjacent RBs in the f...

Abstract

The invention discloses a signal transmission method, related equipment and a system. The method can comprise the steps: a terminal receives resource scheduling information sent by network equipment,wherein the resource scheduling information is used for indicating the network equipment to allocate a second resource set to the terminal, the second resource set comprises at least one resource block, the at least one resource block is from a first resource set, and the first resource set comprises an integer number of resource blocks which are uniformly distributed on a frequency domain; and the terminal conducts uplink transmission on a monitored idle frequency domain resource according to the resource scheduling information, wherein uplink transmission occupies multiple time units, the resource structure of the resource block for uplink transmission on each time unit is the same as the resource structure of the second resource set, and the frequency positions of the resource blocks for uplink transmission on the adjacent time units are different. According to the signal transmission method, the related equipment and the system, the accumulated transmission bandwidth in a certain time can meet OCB requirements, and more flexible resource allocation can be achieved.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a signal transmission method, related equipment and system. Background technique [0002] The rapid development of wireless communication technology has led to an increasing shortage of spectrum resources, which has promoted the exploration of unlicensed frequency bands. However, there are many regulatory restrictions on the use of unlicensed frequency bands. On the one hand, the channel bandwidth occupancy rate (Occupancy Channel Bandwidth, OCB) of the signal in the unlicensed frequency band is limited. The European Telecommunications Standards Institute (ETSI) stipulates that in the 2.4GHz and 5GHz frequency bands, the signal transmission bandwidth is required to occupy more than 80% of the system bandwidth, while for the 60GHz frequency band, the signal transmission bandwidth is required to occupy the system bandwidth. 70% or more. As for the transmission...
