Embodiment Construction

[0030] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0031] A method for allocating physical layer control channel resources provided by the present invention, such as figure 1 As shown, it mainly includes the following steps:

[0032] Step 101, configuring a dedicated CCE resource area for downlink dynamic scheduling PDCCH.

[0033] The dedicated CCE resource area for the downlink dynamic scheduling PDCCH can be configured by the system side and notified to the user equipment (UE, User Equipment) in a broadcast form, and the configuration form can be the ratio of the dedicated CCE resource area to the total CCE resource area.

[0034] It should be noted that the above is only a typical configuration method of the dedicated CCE resource area of ​​the downlink dynamic scheduling PDCCH. In practical applications, the system can flexibly choose other configuration method...

Abstract

The invention discloses a method for allocating physical layer control channel resources, which comprises the steps of: allocating a special control channel unit (CCE) resource region for a physical downlink control channel (PDCCH) of downlink dynamic dispatching; selecting a CCE resource of PDCCH of the downlink dynamic dispatching from the allocated special CCE resource region, and initiating a CCE index according to the selected CCE resource of PDCCH, and allocating a physical uplink control channel (PUCCH) resource occupied by control information feedback corresponding to the current downlink dynamic dispatching. The invention further discloses a device for allocating the physical layer control channel resources. Through the method and the device, the problem that the span of user uplink acknowledgement / negative acknowledgement (ACK / NACK) feedback PUCCH resources is enlarged caused by the occupation of other types of CCE resources of PDCCH can be effectively avoided, thereby reducing the resource waste in the allocation of PUCCH resources, enlarging the effective data transmission resources of the system, and improving the system performance.

Description

technical field [0001] The invention relates to resource allocation technology in a long-term evolution (LTE) system, in particular to a method and device for allocating physical layer control channel resources. Background technique [0002] In the wireless communication system, the definition of the control channel is ubiquitous, and its functions generally include transmitting broadcast information, signaling interaction information, and auxiliary control information for service information, etc. Wherein, the auxiliary control information for service information includes service data scheduling control information, acknowledgment / non-acknowledgement (ACK / NACK) feedback message for traffic channel transmission data in Hybrid Automatic Repeat Request (HARQ, Hybrid Automatic Repeat Request) technology, and the like. [0003] In the third-generation mobile communication Long Term Evolution (LTE, Long Term Evolution) system, control channels still exist, and are defined as Phys...
