Embodiment 1

[0098] In this embodiment, with 20MHz system bandwidth (N_UL_RB=100 physical resource blocks PRB, the number of PRB is 0-99; there are N_Interlace=10 virtual alternating units; each virtual alternating unit has 10 virtual resource blocks VRB; each Each virtual alternate unit has 10 physical resource blocks PRB; one virtual resource block VRB contains one physical resource block PRB), the base station allocates a virtual alternate unit (Interlace_Length=1) in the downlink control information DCI and allocates the first virtual The interlace unit (Interlace_Start=0) uses the resource indication value RIV (decimal) to indicate which virtual interlace unit is allocated as an example for illustration. Can refer to Figure 3 to Figure 7 .

[0099] Since one virtual alternating unit is allocated, and the virtual alternating unit includes 10 VRBs (also 10 PRBs), 10 clusters are allocated, and the unit of a cluster is a resource block. These resource blocks can be continuous or discr...

Embodiment 2

[0110] In this embodiment, with 20MHz system bandwidth (N_UL_RB=100 physical resource blocks PRB, the number of PRB is 0-99; there are N_Interlace=10 virtual alternating units; each virtual alternating unit has 10 virtual resource blocks VRB; each Each virtual alternate unit has 10 physical resource blocks PRB; one virtual resource block VRB contains one physical resource block PRB), the base station allocates a virtual alternate unit in the downlink control information DCI and allocates the first virtual alternate unit, using 10 A bitmap of bits (binary value "1000000000"; MSB corresponds to the virtual alternate unit with the smallest number) to indicate which virtual alternate unit is allocated is used as an example for illustration. Can refer to Figure 3 to Figure 7 .

[0111] Since one virtual alternating unit is allocated, and the virtual alternating unit includes 10 VRBs (also 10 PRBs), 10 clusters are allocated, and the unit of a cluster is a resource block. These r...

Embodiment 3

[0121] In this embodiment, with 20MHz system bandwidth (N_UL_RB=100 physical resource blocks PRB, the number of PRB is 0-99; there are N_Interlace=10 virtual alternating units; each virtual alternating unit has 10 virtual resource blocks VRB; each Each virtual alternate unit has 10 physical resource blocks PRB; one virtual resource block VRB contains one physical resource block PRB), the base station allocates 2 virtual alternate units in the downlink control information DCI and allocates the first virtual alternate unit and the second virtual alternate unit 10 virtual alternating units, using the combined values ​​corresponding to the 9-bit S0=1, S1=1, S2=10, S3=10 points to indicate which virtual alternating units are allocated as an example for illustration. Can refer to Figure 3 to Figure 7 .

[0122] Since 2 virtual alternating units are allocated, and the virtual alternating units include 10 VRBs (also 10 PRBs), 20 clusters are allocated, and the unit of a cluster is a...

Abstract

The present invention provides an up channel information and / or signal sending method and device. The method comprises: receiving down control information DCI from a base station; and sending up channel information and / or signals according to the sending resource indicated by the DCI, wherein the sending bandwidth corresponding to the sending resource at least occupies 80% of uplink system bandwidth. The bandwidth problem can be solved that the 80% occupation of radio transmission cannot be realized in the prior art.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending uplink channel information and / or signals. Background technique [0002] At present, the 3rd Generation Partnership Project (3GPP for short) has completed the standardization of the downlink communication (base station transmission, UE reception) part of Licensed Assisted Access (Licensed Assisted Access, short for LAA). In the next period of time, 3GPP will carry out the standardization work of the uplink communication (UE transmission, base station reception) part of LAA. [0003] According to the requirements of European radio regulation (EN 301 893), a device using an unlicensed carrier must meet the requirement of occupying 80% of the bandwidth when performing radio transmission. For example, for a system bandwidth of 20MHz, a radio transmission device must occupy at least 20*80%=16MHz of bandwidth. But the requirement (EN 301 893) does no...
