Embodiment 1

[0085]In this embodiment, a 5MHz (including 25 RBs) backward compatible carrier and a 1.4MHz (including 6 RBs) fragmented carrier are used for aggregation of the UE of the new version.

[0086] 1. Determination of RBG size:

[0087] Such as figure 2 As shown, UE 1 only uses a 5MHz backward-compatible carrier, and the RBG size corresponding to UE1 is determined as follows: After the eNB configures UE 1 to use a 5MHz backward-compatible carrier, the new carrier bandwidth is 25 (that is, the number of RBs is 25), According to Table 1, the corresponding RBG size is 2;

[0088] UE 2 aggregates and uses a 5MHz backward compatible carrier and a 1.4MHz fragmented carrier, and determines the RBG size corresponding to UE 2 as follows: After the eNB configures UE 2 to use a 1.4MHz fragmented carrier and a 5MHz backward compatible carrier The sum of carrier bandwidths is 31 (that is, the number of RBs is: 6+25=31). According to Table 1, the corresponding RBG size is 3.

[0089] This w...

Embodiment 2

[0096] The main difference between this embodiment and the first embodiment lies in the different RBG division methods when the UE aggregates and uses backward compatible carriers and fragmented carriers.

[0097] Specifically, in the first embodiment, all RBs contained in the compatible carrier and the fragmented carrier are regarded as a whole, and the RBG division is performed; while in this embodiment, the RBs contained in the backward compatible carrier and the fragmented carrier are regarded as two parts, and the RBG is performed separately. divided.

[0098] Such as image 3 As shown, for UE 2, RBG division is performed on the RBs of the backward compatible carrier and the RBs of the fragmented carrier according to the determined RBG size (3). The numbering rules are as follows: RBGs of backward compatible carriers are numbered from 0, and RBGs of fragmented carriers are numbered continuously from the maximum value of RBG numbers of backward compatible carriers.

[00...

Embodiment 3

[0103] The method of determining the RBG size in this embodiment is the same as that in Embodiment 1, the main difference lies in the method of RBG numbering.

[0104] Wherein, the RBG encoding method when UE 1 only uses the backward compatible carrier is the same as that in Embodiment 1, and will not be repeated here. For the case where the UE 2 uses the backward compatible carrier and the fragmented carrier, in this embodiment, the RBs included in the backward compatible carrier and the fragmented carrier are respectively divided into RBGs, and the numbers start from 0 respectively.

[0105] Such as Figure 4 As shown, for UE 2, the RBs (31) contained in its carrier bandwidth are divided into two parts: backward compatible carrier and fragmented carrier, and the RBs in these two parts are divided into RBG according to the determined RBG size (3). , the numbering rule is: RBGs of backward compatible carriers are numbered from 0, and RBGs of fragmented carriers are also numbe...

Abstract

The invention discloses a method for determining a size and a number of a resource block group (RBG) after fragmentation carrier configuration. The method includes that when an enhanced node B (eNB) configures a fragmentation carrier for user equipment (UE), the eNB and the UE can determine that the size of the RBG is equal to a size of a RBG corresponding to a sum of the fragmentation carrier and a bandwidth of a downward compatible carrier which is used by matching with the fragmentation carrier; and according to the determined size of the RBG, a resource block (RB) of the downward compatible carrier and an RB of the fragmentation carrier are treated as a whole or two portions to be subjected to RBG division, and the divided RBG of the downward compatible carrier and the RBG of the fragmentation carrier are numbered. The invention further discloses a device for determining the size and the number of the RBG after the fragmentation carrier configuration. By means of the method and the device, the problem that the resource allocation is mixed due to the fact that the sizes of the RBGs of different versions of UEs are not unified after the fragmentation carrier configuration can be solved.

Description

technical field [0001] The present invention relates to the field of mobile wireless communication, in particular to a method and a device for determining the size and number of a resource block group (RBG) after a fragmented carrier is configured. Background technique [0002] With the development of the mobile communication industry and the increasing demand for mobile data services, people have higher and higher requirements for the speed and quality of service (Qos) of mobile communication. Therefore, before the third generation of mobile communication (3G) has not yet Before large-scale commercial use, the research and development work on the next generation mobile communication system has already begun. The typical example is the Long Term Evolution (LTE) project launched by the Third Generation Partnership Project (3GPP). The highest carrier that the LTE system can provide The bandwidth is 20MHz (megahertz). [0003] With the further evolution of the network, evolved...
