Embodiment Construction

[0039] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present disclosure. Additionally, it should be understood that although the present disclosure is described primarily in the context of an uplink channel of a 3GPP LTE cellular network, this should not be viewed as limiting the scope of the present invention to the aforementioned systems. Other wireless systems including WCDMA, WiMax, UMB, GSM and WLAN may also benefit from utilizing the ideas presented within this disclosure.

[0040] Terms such as NodeB and UE should be considered non-limiting and do not imply a certain hierarchical relationship between the two; ...

Abstract

A method and a serving NodeB (28) for adjusting transmit power of a User Equipment (UE) (31 ) having multiple transmitter chains to reduce relative phase discontinuity (RPD) between a Sounding Reference Signal (SRS) and a Physical Uplink Shared Channel (PUSCH). The NodeB receives from the UE, an RP characteristic (32) of the UE and, based on the RP characteristic, selects an SRS or PUSCH transmit power level (39) for the UE so as to reduce the RPD. The NodeB instructs the UE to set the SRS or PUSCH transmit power level to the level selected by the NodeB.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C §119(e) to US Provisional Application No. 61 / 545,736, filed October 11, 2011, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to wireless communication systems. More specifically, and not by way of limitation, certain embodiments of the invention are directed to adjusting transmission power of a user equipment (UE) to reduce transmissions on sounding reference signals (SRS) and physical uplink shared channels (PUSCH) The relative phase discontinuity (RPD) between the method and the serving NodeB. Background technique [0004] Multiple Input Multiple Output (MIMO) is a key element of the air interface for high speed wireless communication for many wireless communication technologies such as Long Term Evolution (LTE) and High Speed ​​Packet Access (HSPA). MIMO can use diversity i...
