Description

무선통신 시스템의 무선자원 할당방법{METHOD FOR ALLOCATING RADIO RESOURCE IN RADIO COMMUNICATION SYSTEM} Radio resource allocation in a wireless communication system {METHOD FOR ALLOCATING RADIO RESOURCE IN RADIO COMMUNICATION SYSTEM}

본 발명은 무선통신 시스템의 무선자원 할당방법에 관한 것으로서, 특히 TDD-TDMA-SDMA방식을 기반으로 하는 무선 통신시스템에서의 무선자원 할당방법에 관한 것이다. The present invention relates to a radio resource allocation method in a radio communication system as related to a radio resource allocation method in a wireless communication system, in particular based on a TDD-TDMA-way SDMA.

일반적으로 TDD-TDMA-SDMA방식의 무선 통신시스템에서는 사용자 단말에게 상향 및 하향링크의 무선 자원을 할당하여 사용자 단말과 통신을 수행한다. In general, the TDD-TDMA-SDMA scheme in a wireless communication system are assigned to the user terminal the radio resources of the uplink and downlink to perform communication with the user terminal.

도 1은 종래의 TDD-TDMA-SDMA시스템의 자원할당 방법을 나타낸 도면이다. 1 is a view showing a resource allocation method of a conventional TDD-TDMA-SDMA system.

도 1에 도시된 바와같이, TDD-TDMA-SDMA시스템은 각각 상향 및 하향 링크를 동일한 수의 슬롯으로 나눈 다음 각 슬롯마다 다수의 공간채널을 형성하여 사용자들에게 할당한다. As shown in Figure 1, the TDD-TDMA-SDMA system allocates to users to form a plurality of spatial channels for each slot, and then by dividing each of the uplink and downlink respectively into the slots of the same number. 이 경우 TDD-TDMA-SDMA시스템은 상향 및 하향링크의 대칭되는 무선자원을 쌍으로 할당해 주는데, 예를들면, 사용자 1은 상향 링크에서 슬롯 1과 공간채널 1을 할당받고, 하향링크에서는 슬롯 1과 공간채널 1을 할당받아 점유한다. In this case, TDD-TDMA-SDMA system is up and juneunde allocate symmetrical pair of radio resources of the downlink, for example, user 1 is allocated slots 1 and a spatial channel 1 in the uplink, the downlink slot 1 It occupies the space allocated to CH1. 이를 위하여 TDD-TDMA-SDMA시스템은 사용자 단말과 데이터 및 시그널링(전력제어 신호, ACK/NAK신호 등)을 주고 받는다. For this TDD-TDMA-SDMA, the system is to give the user terminal and the data and signaling (power control signal, ACK / NAK signal or the like).

그런데, 종래의 TDD-TDMA-SDMA 시스템은 무선자원을 할당할 때 상하향 링크의 무선자원을 쌍으로 할당해 주기 때문에 만약 트래픽이 없는 사용자가 무선자원을 점유하는 상황이 발생할 수 있어 무선자원이 낭비되는 단점이 있었다. However, the conventional TDD-TDMA-SDMA system is that if the traffic is user radio resource waste can cause this situation to seize the radio resource is not because it is assigned to a pair of radio resources of uplink and downlink links to allocate radio resources there were drawbacks. 즉, 상 하향링크중에서 어느 한 링크에만 데이터와 시그널링이 모두 존재하고 다른 한 링크에는 시그널링만 있는 경우에는 무선자원의 낭비가 심하다. That is, all data and signaling to only one link exists in the downlink and the other link is severe there is a waste of radio resources if only signaling.

예를들어, 사용자 1~8은 상하향 링크 모두에서 데이터와 시그널링을 갖지만 사용자 9는 상향 링크에만 데이터와 시그널링을 갖고 하향 링크에서는 단지 시그널링만 갖는다고 가정해 보자. For example, let's assume that the user 1-8 has the data and signaling on both uplink and downlink link to the user 9 has a data and signaling only in the uplink in the downlink only has only signaling. 이 경우 하향링크에서 슬롯 3의 공간채널 3은 오직 시그널링(데이터에 비해 현저히 적은 양)만을 보내기 위하여 사용되므로 자원이 비효율적으로 사용되는 문제가 있다. In this case, there is a problem that since the spatial channel 3 of slot 3 in the DL is used only to send only signaling (significantly less than the data) resources are inefficiently used.

따라서, 본 발명의 목적은 상하향링크에서 무선자원을 효율적으로 할당할 수 있는 무선통신 시스템의 무선자원 할당방법을 제공하는데 있다. Accordingly, it is an object of the present invention to provide a radio resource allocation method of a wireless communication system that can efficiently allocate radio resources in the uplink and downlink links.

본 발명의 다른 목적은 데이터 및/또는 시그널링을 갖는 사용자를 구분하여 무선자원을 할당할 수 있는 무선통신 시스템의 무선자원 할당방법을 제공하는데 있다. Another object of the present invention to provide a radio resource assignment method for the data and / or the separation of the user with the signaling radio communication system capable of allocating a radio resource.

상기와 같은 목적을 달성하기 위하여 본 발명에 따른 무선통신 시스템의 무선자원 할당방법은 상하향링크에서 데이터와 시그널링이 모드 있는 사용자와 시그널링만 있는 사용자를 구분하여 무선자원을 할당하는 것을 특징으로 한다. Radio resource allocation method of a wireless communication system according to the present invention in order to accomplish the above object, is the separation of the user with only the user and signaling data with the signaling mode in uplink and downlink link is characterized in that assigning the radio resources.

바람직하게, 상기 시그널링만 있는 사용자의 시그널링 신호는 특정 무선자원에만 한정되어 할당된다. Preferably, the signaling signal of a user with only the signaling is assigned is limited to a certain radio resource.

바람직하게, 상기 사용자의 시그널링 신호는 특정 공간채널의 타임슬롯을 시분할하여 할당되는 것을 특징으로 한다. Preferably, the signaling signal of the user is characterized in that the allocation to the time division time slots of a particular spatial channel.

바람직하게, 상기 모든 사용자가 데이터와 시그널링을 상하향 링크에서 송수신할 경우 시그널링을 위해 할당된 무선자원을 일반 무선자원처럼 분할하여 사용한다. Preferably, the use by the user and all dividing the radio resources assigned to the signaling for sending and receiving data and signaling on the uplink and downlink radio resources as a normal link.

바람직하게, 상기 시그널링을 위해 할당된 무선자원은 타임슬롯인 것을 특징으로 한다. Preferably, the radio resources allocated for the signaling is characterized in that time slot.

이하 본 발명의 바람직한 실시 예를 설명하면 다음과 같다 Hereinafter will be described a preferred embodiment of the present invention;

본 발명은 TDD-TDMA-SDMA방식을 기반으로 하는 무선 접속망 시스템에서 구현된다. The invention is implemented in the radio access network system that is based on the TDD-TDMA-way SDMA. 그러나, 본 발명은 다른 표준에 따라 동작하는 통신 시스템에도 적용되어질 수 있다. However, the present invention may be applicable to communication systems operating according to other standards.

본 발명은 TDD-TDMA-SDMA 시스템에서 자원을 할당할 때 상하향 링크의 자원을 쌍으로 할당할 때 데이터(트래픽) 없이 단지 시그널링만 보내는 사용자를 위한 채널을 따로 할당하고 나머지 무선 자원에는 데이터 사용자를 할당하는 방법을 제안한다. The invention TDD-TDMA-SDMA when in the system allocates resources separately assigns a channel for the user only to send signaling only without data (traffic) when allocating the resources of the uplink and downlink links in pairs, and assign the data user, the remaining radio resources we propose a method. 이를 위하여 본 발명은 시그널링 신호만을 위한 무선자원을 따로 설정하고 나머지 자원은 상하향 링크에 대칭적으로 할당한다. To this end, the invention set aside radio resources for only the signaling signal, and the remaining resources are symmetrically allocated to the uplink and downlink links.

도 2는 본 발명에 따른 무선통신 시스템의 자원할당 방법을 나타낸 도면이다. 2 is a view showing a resource allocation method in a wireless communication system according to the present invention.

도 2에 도시된 바와같이, TDD-TDMA-SDMA시스템은 상향링크에서 진한 바탕의 자원 즉, 슬롯 1 및 슬롯 2의 공간채널 1, 2 ,3 과 슬롯 3의 공간채널 1, 2을 데이터와 시그널링이 모두 있는 사용자에게 할당한다. As shown in Figure 2, the TDD-TDMA-SDMA system resources in the dark background in uplink i.e., slot 1 and slot 2 of the spatial channels 1, 2, 3, and slot three spatial channels 1, 2, the data and signaling It is assigned to all users. 여기서, 상기 시그널링은 전력제어 및 ACK/NAK 등의 신호를 나타낸다. Here, the signaling represents a signal such as power control and ACK / NAK.

그리고, TDD-TDMA-SDMA시스템은 슬롯 3의 공간채널 3은 다시 시간 분할하여 시그널링만 있는 사용자에게 할당한다. And, TDD-TDMA-SDMA system to spatial channel 3 is again divided time slot 3 is allocated to the user in signaling only. 즉, 시그널링만 있는 사용자의 시그널링 신호는 특정 무선자원에만 한정되어 할당되며, 특히, 모든 사용자가 데이터와 시그널링을 상하향 링크에서 송수신할 경우에는 시그널링을 위해 할당된 무선자원은 일반 무선자원처럼 분할하여 사용될 수 있다. I.e., the signaling, only and signaling signals for a user who is assigned is limited to a specific radio resources, in particular, all users are sending and receiving data and signaling on the uplink and downlink link, the radio resources allocated for the signaling is used to divide as a normal radio resources can.

예를들어, 도 1에 도시된 바와같이 사용자 1~3은 하향 링크에는 데이터와 시그널링이 있고 상향링크에는 시그널링만 존재하기 때문에 본 발명은 슬롯 3을 시분할하여 사용자 1~3이 상향링크의 슬롯 3의 공간채널 3에서 시그널링을 받도록 한다. For example, some users 1-3 is DL, the data and the signaling and the uplink there is present only the signaling because the present invention by time-sharing the slot 3 users 1-3 are slots on the up-link 3, as shown in Figure 1 and to receive the signaling channel from the space 3. 반면에, 사용자 4~8은 상하향 링크에서 모두 데이터와 시그널링을 주고 받기 때문에 대칭적으로 상하향 무선자원을 할당한다. On the other hand, the users 4-8 are assigned to the uplink and downlink radio resources are symmetrically because give the data and signaling both in the uplink and downlink links. 또한, 사용자 9~11은 상향 링크에만 데이터가 있기 때문에 상향링크의 슬롯 3의 공간채널 3에서 시그널링을 받는다. In addition, the user 9-11 receives the signaling in the spatial channels of the uplink slots 33 because there is only uplink data.

따라서, 상기와 같은 할당방법을 사용할 경우 본 발명은 더 많은 사용자를 수용할 수 있다. Accordingly, the present invention when using the allocation method as described above can accommodate more users. 즉, 종래의 방식대로 자원을 할당할 경우에는 도 1에 도시된 바와같이 최대 9명밖에 접속할 수 없었지만 도 2에서와 같이 11명까지 접속할 수 있게 되어 시스템용량을 확장시킬 수 있게 된다. In other words, in a conventional manner to be able to connect, if the resource is assigned to up to 11 people, such as the outside could not connect to 9 persons in Fig. 2 as shown in Figure 1 it is possible to extend the system capacity.

상술한 바와같이, 본 발명은 TDD-TDMA-SDMA시스템에서 무선자원을 할당할 때 데이터와 시그널링을 모드 갖는 사용자와 시그널링만을 갖는 사용자를 구분하여 무선자원을 할당함으로써 상하향 링크의 무선자원을 효율적으로 할당함은 물론 시스템의 수용능력을 증대시킬 수 있는 효과가 있다. Thus, the present invention is TDD-TDMA-SDMA system, efficient allocation of radio resources of the uplink and downlink link by allocating the radio resource to identify the user having only the user and the signaling with the data and signaling mode when allocating radio resources in the described above there are also, as well as effects which may increase the capacity of the system.

그리고, 본 발명은 도면에 도시된 실시 예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 본 기술 분야의 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시 예가 가능하다는 점을 이해할 것이다.
