A PUCCH resource allocation method in LTE-A

Abstract

The present invention involves a PUCCH resource allocation method in a LTE‑A, including: the field of the wireless resource control layer in the use of a signal N1‑Pucch‑an‑cs‑list‑r10 to allocate resources for the user equipment, to the same two of the same twoPUCCH LIST resource, which uses positive sequence pairing and upside -order pairing to configure the PUCCH 1B CS resource pair for the user device. Among them, the PUCCH 1B CS resource indicates the PUCCH resources used in the auxiliary community for dynamic scheduling business.The scheduling business, and using the fields in the signal N1PUCCH‑AN‑PersisistentList and N1PUCCCHAN‑ANTLISTP1‑R10 to allocate resources for the user equipment, use the two ways of positive pairing and backflow pairing of the same two PUCCCHLIST resources.Configure the semi -static scheduling PUCCH 1X resource pair for the user's device.Through the above technical schemes, high -level signaling can be effectively distributed reasonably, and PUCCC 1X resources are reused among multi -users, and the PUCCCH resource utilization rate of PUCCH resources is used to configure the configuration method in LTE‑A.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a method for configuring PUCCH resources in LTE-A. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution system) system, LTE-A (LTE-Advanced, advanced long-term evolution system) is an evolved version of LTE, in order to meet the LTE-A downlink peak speed of 1Gbps, uplink peak speed of 500Mbps requirements , it is necessary to provide a maximum transmission bandwidth of 100MHz, but due to the scarcity of continuous spectrum with such a large bandwidth, LTE-A proposes a carrier aggregation (Carrier Aggregation, CA) solution. The so-called carrier aggregation is to aggregate two or more carrier units (Component Carriers, CCs) together to support a maximum transmission bandwidth of 100 MHz. [0003] In the LTE system, PUCCH (Physical Uplink Control CHannel, physical uplink control channel) mainly carries SR (Schedule Request, scheduling ...

Problems solved by technology

[0017] The second problem is that due to the PUCCH1B CS and PUCCH two-antenna port diversity transmission mechanism introduced in LTE-A, at most two PUCCH resources need to be allocated to one terminal, but not all terminals and all scenarios are fixedly allocated two PUCCH resources. PUCCH resources, according to different scenarios, UE can allocate one or two PUCCH resources

First, both solutions are equivalent to configuring a unique pair of available SPS configurations for the UE, so that even if the UE is not scheduled this time, the PUCCH resource position is still reserved, causing unnecessary waste; second , Scheme 1 does not use the flexible scheduling function of the PDCCH field, and Scheme 2 uses the function of the PDCCH field, but the actual allocation results and effects are the same, and no obvious benefits are introduced

Finally, these allocation schemes do not specifically consider how to efficiently use PUCCH resources when a single PUCCH resource and two PUCCH resources are configured for LTE-A.
