Embodiment 1

[0067] Embodiment 1 of the present invention provides a resource acquisition method in a multi-antenna port scenario. The resource acquisition method includes but is not limited to a resource acquisition method for PUCCH format 1b with channel selection during multi-antenna port transmission. The antenna port includes but is not limited to Antenna port of PUCCH, and the method can be applied to transmit diversity schemes such as E-SORTD, M-SORTD (Modified SORTD, improved SORTD), RSTD, and of course can also be applied to other schemes, and will not be repeated in the embodiments of the present invention. .

[0068] Such as image 3 As shown, the resource acquisition method in the multi-antenna port scenario includes the following steps:

[0069] Step 301, the terminal device determines the uplink control information to be sent.

[0070] Step 302, the terminal device receives the resource indication information sent by the base station device, and obtains K candidate PUCCH re...

Embodiment 2

[0089] The above-mentioned embodiment 1 is for the processing of terminal equipment, and correspondingly, for the processing of base station equipment, embodiment 2 of the present invention provides a resource configuration method in a multi-antenna port scenario. The resource configuration method includes but is not limited to PUCCH format 1b with The resource acquisition method of channel selection during multi-antenna port transmission, the antenna port includes but not limited to the antenna port of PUCCH, and this method can be applied to transmit diversity schemes such as E-SORTD, M-SORTD, RSTD, etc., of course it can also be applied For other solutions, details will not be described in this embodiment of the present invention. Such as Figure 4 As shown, the resource configuration method in the multi-antenna port scenario includes the following steps:

[0090]Step 401, the base station device determines K candidate PUCCH resources used by the terminal device for channe...

Embodiment 3

[0106] In this embodiment, the FDD system is taken as an example, such as Figure 5 The FDD system scheduling diagram shown in the figure assumes that the terminal equipment uses PUCCH format 1b with channel selection to transmit 3-bit ACK / NACK information, and uses 2 antenna ports for transmission. The ACK / NACK mapping table is shown in Table 1 or Table 3. The specific steps are as follows:

[0107] Step 1. The base station device configures 4 channel resources for 2-antenna port transmission to the terminal device.

[0108] Method 1: The base station equipment determines four PUCCH format 1b channel resources, which are respectively And notify the terminal equipment through RRC signaling.

[0109] It can be seen from the above ACK / NACK mapping table that there are P=2 pairs of resource pairs in the mapping table, which are composed of two different channel resources respectively used to transmit data symbols and pilot symbols corresponding to the same ACK / NACK feedback inf...

Abstract

The invention discloses a resource acquisition method under a multi-antenna port scene, a configuration method thereof and equipment. The acquisition method comprises the following steps: terminal equipment determines uplink control information to be sent; according to received resource indication information, the terminal equipment acquires K candidate PUCCH (physical uplink control channel) resources needed for channel selection in multi-antenna port transmission, and the K candidate PUCCH resources comprise at least P pairs of resources with different resources, wherein, two resources in each pair of resources are in a same PRB (physical resource block); to each antenna port, according to the uplink control information to be sent, the terminal equipment selects L resources in the K candidate PUCCH resources, the L resources are respectively used for transmitting a data symbol and a pilot frequency symbol which are corresponding to the uplink control information to be sent, and the L resources are in a same PRB; at each antenna port, the terminal equipment uses a resource corresponding to a selected data symbol to send the data symbol, and uses a resource corresponding to a selected pilot frequency symbol to send the pilot frequency symbol. According to the methods and the equipment in the invention, performance gain of PUCCH transmit diversity is ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a resource acquisition method, a configuration method and a device thereof in a multi-antenna port scenario. Background technique [0002] (1) PUCCH (Physical Uplink Control Channel, physical uplink control channel) format (format) 1b with channel selection (PUCCH format 1b with channel selection) scheme. [0003] In LTE-A (Long Term Evolution-Advanced, advanced long-term evolution) Rel-10 (Release 10, version 10), PUCCH format 1b with channel selection can be used to transmit ACK (Acknowledgment, positive confirmation) / NACK not exceeding 4 bits (Non-Acknowledgment, negative acknowledgment) feedback information, and M bits of PUCCH format 1b resources need to be used for transmitting M-bit feedback information; where M=2, 3, 4. [0004] According to the ACK / NACK state to be fed back, the terminal queries the corresponding ACK / NACK mapping table, selects one ...
