Problems solved by technology

Then, if there are few terminals performing PUCCH transmission in the dynamic HARQ-ACK area, the resource usage efficiency will be reduced; in addition, since the PDCCH resources of different cells (that is, the CCEs carrying DCI) are allocated to each terminal independently, therefore When terminals in different cells perform HARQ-ACK transmission, the PUCCH resources used are likely to collide, resulting in a significant drop in transmission performance

Embodiment Construction

[0041] In order to improve the utilization rate of PUCCH resources and ensure the transmission performance of PUCCH at the same time, in the embodiment of the present invention, the UE adopts the frequency hopping pattern agreed with the network side, and determines the frequency hopping mode allocated by the network side to the UE in the dynamic PUCCH resource area. The PUCCH resource, where the PUCCH resource may be a PUCCH resource carrying HARQ-ACK transmission, or / and, CQI (Channel Quality Indicator, channel quality indicator) transmission.

[0042] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] refer to Figure 4 As shown, in the embodiment of the present invention, the network side device (such as a base station) includes a communication unit 40 and a processing unit 41, wherein,

[0044] A communication unit 40, configured to determine the starting position of the PUCCH resource ...

Abstract

The invention relates to the communication field and discloses a PUCCH (physical uplink control channel) resource determination method and apparatus. The method comprises the following steps: based on PUCCH resource initial positions notified at a network side and sizes of dynamic PUCCH resource areas, UE determines, through frequency hopping patterns agreed at the network side, distributed PUCCH resources within the dynamic PUCCH resource areas via a frequency hopping mode. Therefore, the sizes of dynamic PUCCH resource areas are effectively reduced, resource spending is reduced, and probabilities of conflicts among PUCCH resources of different kinds of UE are minimized. Meanwhile, the utilization rate of PUCCH resources is effectively increased, orthogonal PUCCH transmission among districts is supported, and then the PUCCH transmission performance is substantially improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for determining PUCCH resources. Background technique [0002] In the current standard, HARQ-ACK (Hybrid Automatic Repeat request-ACK, hybrid automatic repeat request response) can be transmitted through several PUCCH Formats (Physical Uplink Control Channel Format, physical uplink control channel format), for example, PUCCH Format1a / 1b / 3. The contents of their respective transmissions are introduced as follows: [0003] 1) Use PUCCH format 1a to transmit 1-bit HARQ-ACK information, or, in the case of FDD (Frequency division duplex, frequency division duplex), use PUCCH format 1a to transmit 1-bit HARQ-ACK and positive SR (Scheduling Request, SR) joint transmission. [0004] 2) Use PUCCH format 1b to transmit 2-bit HARQ-ACK or jointly transmit 2-bit HARQ-ACK and positive SR. [0005] 3) When the UE in the FDD system is configured with more than one servin...
