Embodiment 1

[0630] Assuming that both sides of the R8 / 9 / 10 backward compatible component carrier are configured to use a new type of carrier, the new type of carrier can be a fragmented carrier, an extended carrier or other non-backward compatible carriers; taking a fragmented carrier as an example, It is assumed that the two fragmented carriers have the same size and are located on both sides of the backward-compatible component carrier, and the PRB numbering form of the LTE uplink physical resource adopts mode 1. When the system is initialized, it is confirmed that the resource mapping start position of the PUCCH formats of the R11 UE configured to use the fragmented carrier starts from the fragmented carrier. The size relationship of the required PUCCH resource size determines the corresponding mapping rule. When the size of the fragmented carrier is larger than the PUCCH resource size required by the R11 UE configured to use the fragmented carrier, the determination method of the varia...

[0638] Assuming that both sides of the R8 / 9 / 10 backward compatible component carrier are configured to use a new type of carrier, the new type of carrier can be a fragmented carrier, an extended carrier or other non-backward compatible carriers; taking a fragmented carrier as an example, It is assumed that the two fragmented carriers have the same size and are located on both sides of the backward compatible component carrier, and the PRB numbering form of the LTE uplink physical resource adopts the mode 1. When the system is initialized, it is confirmed that the format1 / 1a / 1b and format2 / 2a / 2b resource mapping start position of the PUCCH of the R11 version UE configured to use the fragmented carrier starts from the R8 / 9 / 10 backward compatible component carrier, and the resource mapping of format3 The starting position starts from the fragmented carrier according to the high-level signaling notification. At this time, format1 / 1a / 1b and format2 / 2a / 2b are determined in the same w...

Embodiment 3

[0640]Assuming that both sides of the R8 / 9 / 10 backward compatible component carrier are configured to use a new type of carrier, the new type of carrier can be a fragmented carrier, an extended carrier or other non-backward compatible carriers; taking a fragmented carrier as an example, It is assumed that the two fragmented carriers have the same size and are located on both sides of the backward compatible component carrier, and the PRB numbering form of the LTE uplink physical resource adopts the mode 1. When the system is initialized, it is confirmed that the resource mapping start position of format1 / 1a / 1b and format2 / 2a / 2b of the PUCCH of the R11 version UE configured to use the fragmented carrier starts from the beginning of the fragmented carrier, and the resource mapping start position of format3 is based on the higher layer The signaling notification starts from the R8 / 9 / 10 backward compatible component carrier, which is the same as the situation to be considered in Em...

Abstract

The invention discloses a mapping method of a physical uplink control channel (PUCCH) led into a newly increased type carrier wave scene. The mapping method includes that user experience (UE) configured by a base station uses newly increased type carrier waves, and the newly increased type carrier waves are paired with downward compatible component carrier waves; the base station numbers physical resource blocks (PRBs) in the paired downward compatible component carrier waves and the newly increased type carrier waves; and the base station and the UE carry out PUCCH mapping according to PRB numbering. The invention further correspondingly discloses a base station and UE. According to the mapping method, the base station and the UE, the spectrum resource utilization rate and uplink service handling capacity can be improved.

Description

technical field [0001] The present invention relates to the field of mobile wireless communication, in particular to a mapping method, a base station and a UE of a physical uplink control channel (PUCCH, Physical Uplink Control Channel) under the scenario of introducing a new type of carrier. 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 started. The typical example is the Long Term Evolution (LTE) project launched by the Third Generation Partnership Project (3GPP). The highest frequency spectrum that the LTE system can provide The bandwidth is 20MHz (megahertz). W...
