Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] In the embodiment of the present invention, logical subbands are occupied in the PUCCH. Wherein, the ACK / NACK signal occupies the first symbol and the fourth symbol of the subband; the PUCCH demodulation reference signal occupies the second symbol and the third symbol of the subband. The terminal can perform uplink control through the PUCCH. Since multiple subbands can be occupied in the PUCCH, spectrum resources can be fully used. In addition, since frequency diversity can be used in the case of multiple subbands, the detection performance of ACK / NACK is further improved.

[0058] See attached figure 1 It is a schematic flow chart of a PUCCH resource allocation method, specifically including the following steps:

Abstract

Provided is a resource distribution method for a physical uplink control channel. The method comprises the steps of enabling multi-subband user equipment (UE) to occupy a logic subband in the physical uplink control channel (PUCCH); enabling acknowledgement / negative acknowledgement (ACK / NACK) signals to occupy a first symbol and a fourth symbol of the subband; enabling PUCCH demodulation reference signals to occupy a second symbol and a third symbol of the subband; and enabling a terminal to control an uplink through the PUCCH. The invention further discloses a resource distribution device for the physical uplink control channel. After applying the resource distribution method and device, spectrum resources can be fully utilized, and frequency diversity is further utilized to improve detection performance of ACK / NACK.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a resource allocation method and device for a physical uplink control channel. Background technique [0002] The authorized frequency points of the power communication network are discretely distributed in the frequency band from 223.525MHz to 231.65MHz, a total of 40, each with a bandwidth of 25KHz. The power communication network system adopts the same frequency network, and each cell adopts a multi-channel orthogonal frequency division multiplexing system for network coverage. The multi-channel OFDM system adopts Orthogonal Frequency Division (OFDM) as the basic technology, and each channel is a sub-band carrying effective information. A user (UE) can support single subband or multi-subband transmission and reception, and the most capable UE can support 40 subband services. [0003] Hybrid Automatic Repeat Request (HARQ) technology can improve communi...
