Configuration of measurement time requirements for cell reselection procedures including autonomous closed subscriber group csg cell search and reselection

Abstract

The requirement for measurement time to perform measurements that require the user equipment to tune its receiver to other frequencies is configured differently and depending on the length of the off-period and the measurements to be performed in order to meet the requirements for the measurement various requirements of timing while allowing autonomous reselection to CSG in CELL_FACH. Therefore, one type of user equipment UE performs measurements of various measurement types. The UE performs measurements of the first measurement type on at least one Closed Subscriber Group CSG cell; performs measurements of the second type on at least one carrier frequency of lower priority or equivalent priority compared to the priority of the serving carrier frequency and performing the third measurement type on at least one carrier frequency of higher priority than the priority of the serving carrier frequency. Among the measurements performed: (a) performing at least one of the second and third measurement types of measurements during the required time such that for at least one of the second and third measurement types of measurements A first predefined requirement is fulfilled, the required time forms a portion of the time available for measurements, and (b) measurements of the first measurement type are performed during the remainder of the time, during which no measurements of the second measurement type are performed At least one of the measurement and the measurement of the third measurement type, wherein the required time and the remaining time form different parts of the time available for measurement (for example, the period of the receiver off time of the discontinuous reception DRX cycle), which is determined by Network nodes to configure. The present application is directed to a user equipment, a network node, and a corresponding method.

Description

technical field [0001] Embodiments herein relate to a user equipment, a network node, and methods therein. In particular, it relates to performing measurements of multiple measurement types and configuring user equipment to perform measurements of the multiple measurement types. Background technique [0002] A communication device, such as a terminal, is also known as eg User Equipment (UE), mobile terminal, wireless terminal, and / or mobile station. Terminals are enabled to communicate wirelessly in a cellular communication network or wireless communication system (sometimes also referred to as a cellular radio system or cellular network). Via a radio access network (RAN) comprised within or connected to a cellular communication network and possibly one or more core networks, it is possible, for example, between two terminals, between a terminal and a fixed telephone, and / or perform communication between the terminal and the server. [0003] A terminal may further be ref...

Problems solved by technology

The second possibility is to configure the DRX cycle

In other words, for some DRX configurations, if the UE does not use the entire off-time for measurements for reselection evaluation in CELL_FACH, the UE may not be able to meet the existing measurement requirements
