Embodiment Construction

[0027] Recent proposals have considered the possibility of not restricting Physical Uplink Control Channel (PUCCH) transmissions to the Primary Cell (PCell), as is currently required in Release 12. Thus, PUCCH resources for PUCCH-related signaling are provided for one or more secondary cells (SCells), which may be referred to herein as PUCCH-SCells. However, providing PUCCH resources on the SCell requires signaling for configuring the PUCCH-SCell and serving cells that should be mapped to the PUCCH-SCell.

[0028] Particular embodiments of the present disclosure may provide a solution that enables mapping of control information on a carrier by a wireless device. Certain embodiments may include functionality for mapping one or more serving cells to a certain PUCCH-SCell. in the attached Figure 1-8 Specific embodiments are described in , wherein like numerals are used for like and corresponding parts of the various drawings. figure 1is a block diagram illustrating an embodi...

Abstract

According to certain embodiments, a method by a wireless device (110) is provided for mapping control information on carriers. The method includes receiving, by the wireless device (110), a mapping between at least one serving cell and at least one PUCCH channel. Based on the mapping, a particular PUCCH channel on which PUCCH-related signalling is to be transmitted for a particular serving cell (302K) is determined. The PUCCH-related signalling is transmitted on the particular PUCCH channel.

Description

[0001] priority [0002] This application claims priority to US Patent Provisional Application No. 62 / 145,792, filed April 10, 2015, entitled "Methods for Mapping Control Information on Carriers," the disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure relates generally to wireless communications and, more particularly, to systems and methods for mapping control information on a carrier. Background technique [0004] Carrier aggregation (CA) is considered as one of the key features of LTE-Advanced systems. CA increases the available bandwidth and boosts the achievable data rate by aggregating multiple component carriers (CCs) which can be discontinuous and even operate in different bands (ie in different frequencies). Even operators with fragmented spectrum can provide end users with an enhanced mobile broadband experience in both uplink (UL) and downlink (DL). [0005] CA standardization started with Long Term Evolutio...
