Embodiment 1

[0196]This preferred embodiment provides an enhanced physical hybrid automatic repeat request indication channel resource definition and indication method, which is used to solve the problems of interference and insufficient resources of the traditional physical hybrid automatic repeat request indication channel (PHICH). The method includes: dividing part or all of the RE resources configured for sending ePHICH physical resource block pairs into Group ePHICH resource elements, where an ePHICH group includes ePHICH; one ePHICH resource consists of or an index pair Definitions and instructions, where is the ePHICH group index, is the index of the orthogonal sequence within the ePHICH group, n ePHICH group ∈ [ 0 , N ePHICH group - 1 ] and n ePHICH seq ...

Embodiment 2

[0223] This preferred embodiment provides a resource definition and indication method for an enhanced physical hybrid automatic repeat request indication channel, the method includes the following steps S502 to S508.

[0224] Step S502: The network side configures the physical resource block pair used for sending ePHICH to the terminal side, and notifies the terminal side of the resource information.

[0225] Step S504: The network side divides the physical resource block pairs configured for sending ePHICH into Group ePHCIH resource element (hereinafter also referred to as ePHICH group resource);

[0226] Step S506: The network side configures the group index and the intra-group orthogonal sequence index for the terminal side, and notifies the terminal side of the information;

[0227] Step S508: The terminal side receives the resource indication information of the above step S502 and step S506, and according to the instruction, finds its ePHICH resource position on the ePH...

Embodiment 3

[0269] In this embodiment, it is assumed that there are a total of N physical resource block pairs used for sending ePHICH PRB The number and positions of these ePHICH block pairs are notified by the network side to the terminal side through system messages or high-level signaling, or determined by agreement between the network side and the terminal side. where N PRB non-negative integer, preferably N PRB Equal to 1, 2, 4, 8 or 16.

[0270] The method includes: dividing each physical resource block for sending ePHICH into resource elements other than DMRS into 16 enhanced resource element groups (enhanced Resource Element Group, eREG' for short, adding a apostrophe here is mainly In order to distinguish from the eREG in the ePDCCH), the resource elements in each physical resource block pair are allocated to each eREG in the frequency domain first and then the time domain, for example Figure 9 shown.

[0271] A physical resource block pair for sending ePHICH includes multi...

Abstract

The invention discloses a transmitting method, a transmitting device, a receiving method and a receiving device for an ePHICH (enhanced Physical HybridARQ Indicator Channel). The transmitting method comprises the steps of dividing part or all of resource elements (REs) of a physical resource block pair for transmitting the ePHICH into N<ePHICH><group> groups of ePHICH resource elements, wherein among the N<ePHICH><group> groups of ePHICH resource elements, each group comprises N<ePHICH><seq> ePHICH resources, both N<ePHICH><group> and N<ePHICH><seq> being positive integers greater than or equal to 1; and transmitting the ePHICH on the ePHICH resources. By adopting the method, the transmission performance of the ePHICH is improved.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to an enhanced Physical Hybrid ARQ Indicator Channel (enhanced Physical HybridARQ Indicator Channel, ePHICH for short) sending method and device, receiving method and device. Background technique [0002] The Long Term Evolution (LTE) system is a third generation partnership organization (3 rd Generation Partnership Project (referred to as 3GPP) is an important plan. When the LTE system adopts a regular cyclic prefix (CP for short), a time slot includes uplink / downlink symbols of 7 lengths, and when an extended CP is used in the LTE system, a time slot includes uplink / downlink symbols of 6 lengths. [0003] The following physical channels are defined in the LTE system: [0004] Physical Broadcast Channel (PBCH for short): The information carried by this channel includes the frame number of the system, the downlink bandwidth of the system, the period of the physical hybrid re...
