Problems solved by technology

The maximum number of carriers supported in R11 is 5. Therefore, for example, the number of bits in the carrier indication field and the carrier index or the secondary cell index (Scell ​​index) is 3, which is used to indicate the activation / deactivation state of the MAC control element (MAC CE : MAC Control Element) can support up to 8 carriers, and in R13, it needs to support up to 32 carriers, and the carrier indicator field format, carrier index and MAC CE format of R11 cannot support the activation / deactivation status of 32 carriers

Abstract

The present invention relates to a method and device for indicating a carrier and a carrier state in a wireless communication network. The maximum number of the carriers is N. The method comprises: indicating the activation / deactivation states of all configuration carriers in a single MAC CE or indicating the activation / deactivation states of the carriers in changing carrier groups, wherein each carrier group is associated with one byte of the effective load in the MAC CE which includes a sub header and the effective load. A base can send carrier group identification numbers and carrier subindex to a user device, and the carrier group identification numbers are configured to indicate the carrier group where the carrier subindex is located. Based on the scheme of the invention, compared to the prior art, the signaling overheads for indicating carriers and / or activation / deactivation states of the carriers are reduced and the good compatibility of a current network is maximally realized in the condition of supporting the number of carriers which is more than the number of the R11.

Description

technical field [0001] The present invention relates to a wireless communication network, and more particularly, to a method and device for indicating a carrier and carrier status in a wireless communication network. Background technique [0002] At present, the 3GPP has approved a work project on carrier aggregation enhancement, and this work project will be discussed at the meeting of RAN1 and RAN2. An important function of carrier aggregation enhancement is to support 32 carrier aggregation. According to RAN2's point of view, an important issue in supporting carrier aggregation enhancement in R13 is how to indicate the activation / deactivation status of 32 carriers. The maximum number of carriers supported in R11 is 5. Therefore, for example, the number of bits in the carrier indication field and the carrier index or the secondary cell index (Scell ​​index) is 3, which is used to indicate the activation / deactivation state of the MAC control element (MAC CE : MAC Control ...
