Embodiment 1

[0060] In this embodiment, a resource indication method is provided, Figure 4 is a flowchart of a resource indication method according to an embodiment of the present invention, such as Figure 4 As shown, the process includes the following steps:

[0061] Step S402, allocating resources for more than two user equipment UEs in the access network;

[0062]Step S404, indicating to the UE the resources allocated to the above-mentioned UE; wherein, the resource is used for the UE to send the Physical Uplink Control Channel PUCCH, when at least two UEs among the two or more UEs send the PUCCH using spatial orthogonal resource transmission diversity SORTD Share the same antenna port Antenna port 1 resource.

[0063] Wherein, the above resource indication method may be performed by a network side device, and optionally, the above method may be performed by an eNodeB. In the above embodiment, the resources of the same antenna port Antenna port 1 shared by UEs essentially share the...

Embodiment 2

[0072] The method embodiment provided in Embodiment 2 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, Figure 5 It is a hardware structure block diagram of a mobile terminal according to a method for sending a PUCCH according to an embodiment of the present invention. Such as Figure 5 As shown, the mobile terminal 50 may include one or more ( Figure 5 Only one is shown in ) processor 502 (processor 502 may include but not limited to microprocessor MCU or programmable logic device FPGA and other processing devices), memory 504 for storing data, and transmission device for communication function 506. Those of ordinary skill in the art can understand that, Figure 5 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device. For example, mobile terminal 50 may also include Figure 5 more or ...

Embodiment 3

[0086] In this embodiment, the technical details of the present invention are mainly described. In this embodiment, PUCCHResource-P1 (or P1 for short) is equivalent to the above-mentioned Antenna port 1:

[0087] As shown in attached tables 1-4, different resource allocation examples can be obtained by using different multiplexing coefficients for PUCCH Resource-P1. The resource reuse factor is defined as:

[0088] S=[R_no_shared / R_shared]

[0089] Among them, S represents the multiplexing coefficient, R_no_shared represents the number of P1 resources required when there is no sharing between UEs when the traditional 3GPP solution is adopted, and R_shared represents the number of P1 resources required when the patented method is used for sharing. [] stands for integer rounding, optional rounding, rounding up or rounding down. Here is an example of rounding.

[0090] Attached Table 4 shows the resource occupancy when there is no multiplexing. As shown in Attached Table 4, it...

Abstract

The present invention provides a resource indication method, a PUCCH transmission method, and a network side device. The method includes the following steps: resources are allocated for more than twopieces of user equipment UE in an access network; the resources allocated to the UE are indicated to the UE; the resources are used for the UE to send a physical uplink control channel PUCCH, at leasttwo pieces of UE among the more than two pieces of UE share the same antenna port Antenna port 1 resource when transmitting the PUCCH by using a spatial orthogonal resource transmission diversity SORTD. The method disclosed in the invention helps solve problems of high resource occupation and consumption and low resource utilization rates in technologies of the related art, thereby achieving theeffects of reducing the resource occupation consumption and improving the resource utilization rates.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource indication method, a PUCCH sending method and network side equipment. Background technique [0002] In order to improve the stable transmission of the Physical Uplink Control Channel (PUCCH for short), in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) Rel10 for the user equipment (User Equipment, UE for short) The uplink multi-antenna technology introduces a Space Orthogonal-Resource Transmit Diversity (SORTD for short) technology. [0003] When the UE supports multi-antenna transmission, if the PUCCH transmission can make full use of the multi-antennas and corresponding antenna power amplifiers, it can make full use of power resources and achieve the maximum diversity gain. In order to achieve additional diversity, in Rel-10, 2-antenna SORTD for PUCCH is introduced. The mechanism is also backward compatible with the PUCC...
