Problems solved by technology

The addition of fragmented carriers will bring about an increase in the total number of PRBs, resulting in the situation that the RBGs corresponding to the number of PRBs of backward compatible carriers, fragmented carriers, and aggregated carriers are different, that is, UEs of lower versions and configured with fragmented carriers The RBG size determined by the UE in the new version based on the number of PRBs is inconsistent
Since existing standards do not support resource allocation for two or more UEs with different RBG sizes at the same time, after configuring the sliced ​​carrier, you will face the problem of how to determine the RBG size to clearly indicate resource allocation information

Embodiment 1

[0072] In this embodiment, the new version UE aggregates and uses a 5MHz backward compatible carrier and a 1.4MHz fragmented carrier. When performing resource allocation, the mapping table of carrier bandwidth and RBG size in R8 is used, as shown in Table 1. The RBG size corresponding to the 5MHz backward compatible carrier is 2, and the RBG size corresponding to the 1.4MHz fragmented carrier is 1. According to the division method and numbering method of the present invention: the unified RBG size after aggregation is before and after the fragmented carrier is configured The RBG size of the compatible carrier, that is, the RBG size corresponding to the 1.4MHz chip carrier is also determined to be 2;

[0073] After the RBG size is determined, the RBG of the backward compatible carrier and the RBG of the fragmented carrier are consecutively numbered, specifically: the RB of the backward compatible carrier and the RB of the fragmented carrier are regarded as a whole, and the RBG is d...

Embodiment 2

[0075] In this embodiment, the new version UE aggregates and uses a 5MHz backward compatible carrier and a 1.4MHz fragmented carrier; in resource allocation, the mapping table of carrier bandwidth and RBG size in R8 is used, as shown in Table 1. The RBG size corresponding to the 5MHz backward compatible carrier is 2, and the RBG size corresponding to the 1.4MHz fragmented carrier is 1. According to the division method and numbering method of the present invention: the unified RBG size after aggregation is before and after the fragmented carrier is configured The RBG size of the compatible carrier, that is, the RBG size corresponding to the 1.4MHz chip carrier is also 2;

[0076] After the RBG size is determined, the RBG of the backward compatible carrier and the RBG of the fragmented carrier are consecutively numbered, specifically: the RB of the backward compatible carrier and the RB of the fragmented carrier are regarded as two parts, which are divided according to the determine...

Embodiment 3

[0078] In this embodiment, the new version UE aggregates and uses a 5MHz backward compatible carrier and a 1.4MHz fragmented carrier; in resource allocation, the mapping table of carrier bandwidth and RBG size in R8 is used, as shown in Table 1. The RBG size corresponding to the 5MHz backward compatible carrier is 2, and the RBG size corresponding to the 1.4MHz fragmented carrier is 1. According to the division method and numbering method of the present invention: the unified RBG size after aggregation is before and after the fragmented carrier is configured The RBG size of the compatible carrier, that is, the RBG size corresponding to the 1.4MHz chip carrier is also 2;

[0079] After the RBG size is determined, the RBGs of the backward compatible carrier and the RBGs of the wave-sliced ​​carrier are numbered separately, specifically: the RB of the backward compatible carrier and the RB of the sliced ​​carrier are regarded as two parts, and the RBG sizes are determined according t...

Abstract

A method and a device for determining a RBG after configuring a segment carrier. The method comprises: after an eNB configures a segment carrier, the eNB and a UE determining that the size of an RBG is equal to the size of a RBG corresponding to a backward compatible carrier matching with the segment carrier; and according to the determined size of the RBG, performing RBG division by regarding an RB of the backward compatible carrier and an RB of the segment carrier as a whole or as two parts, and numbering an RBG of the backward compatible carrier and an RBG of the segment carrier obtained through division.

Description

Technical field [0001] The present invention relates to the field of wireless communication, and in particular to a method and device for determining the size and number of RBGs after fragmented carriers are 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, there is no Before large-scale commercial use, research and development work on the next-generation mobile communication system has already begun. A typical example is the Long Term Evolution (LTE) project initiated by the third-generation partnership plan. The highest carrier bandwidth that the LTE system can provide is 20MHz (megahertz). With the further evolution of the network, evolved LTE (LTE-A, LTE-Advanced), as an evolution system of LTE, can provide up to 100MHz carrier bandwidth and support more f...
