Abstract
Aspects of the present disclosure provide techniques that may be utilized by a UE for performing neighbor cell measurement and reselection in narrowband deployment scenarios, such as NB-IoT deployment scenarios. For example, a method for wireless communications by a user equipment (UE), can include determining, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters of at least one neighbor cell, and performing a neighbor cell search with measurement of narrowband reference signals (NRS) based on the one or more transmission deployment mode parameters.
Claims16
A method for wireless communications by a user equipment (UE), comprising:
- determining, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters comprising a number of transmit antennas of at least one neighbor cell, without assistance associated with the one or more transmission deployment mode parameters from the serving cell, wherein the determining comprises:
- inferring the number of transmit antennas used by the at least one neighbor cell by evaluating different hypotheses corresponding to different numbers of transmit antennas, and
- selecting one of the different hypotheses with a higher narrowband reference signal receive power (NRSRP) than another based on the inferring the number of transmit antennas used by the at least one neighbor cell;
- and
- performing a neighbor cell search with measurement of NRSRP based on the determined information regarding the one or more transmission deployment mode parameters.
An apparatus for wireless communications by a user equipment (UE), comprising:
- means for determining, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters comprising a number of transmit antennas of at least one neighbor cell, without assistance associated with the one or more transmission deployment mode parameters from the serving cell, wherein the means for determining comprises:
- means for inferring the number of transmit antennas used by the at least one neighbor cell by evaluating different hypotheses corresponding to different numbers of transmit antennas, and
- means for selecting one of the different hypotheses with a higher narrowband reference signal receive power (NRSRP) than another based on the inferring the number of transmit antennas used by the at least one neighbor cell;
- and
- means for performing a neighbor cell search with measurement of NRSRP based on the determined information regarding the one or more transmission deployment mode parameters.
An apparatus for wireless communication by a user equipment (UE), comprising:
- at least one processor;
- and
- memory coupled to the at least one processor, the memory comprising instructions executable by the at least one processor to cause the UE to:
- determine, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters comprising a number of transmit antennas of at least one neighbor cell, without assistance associated with the one or more transmission deployment mode parameters from the serving cell, wherein the instructions executable by the at least one processor to cause the UE to determine comprises instructions executable by the at least one processor to cause the UE to:
- infer the number of transmit antennas used by the at least one neighbor cell by evaluating different hypotheses corresponding to different numbers of transmit antennas, and
- select one of the different hypotheses with a higher narrowband reference signal receive power (NRSRP) than another based on the inferring the number of transmit antennas used by the at least one neighbor cell;
- and
- perform a neighbor cell search with measurement of NRSRP based on the determined information regarding the one or more transmission deployment mode parameters.
A non-transitory computer readable medium for wireless communication by a user equipment (UE) having instructions stored thereon, the instructions executable by at least one processor to cause the UE to:
- determine, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters comprising a number of transmit antennas of at least one neighbor cell, without assistance associated with the one or more transmission deployment mode parameters from the serving cell, wherein the instructions executable by the at least one processor to cause the UE to determine comprises instructions executable by the at least one processor to cause the UE to:
- infer the number of transmit antennas used by the at least one neighbor cell by evaluating different hypotheses corresponding to different numbers of transmit antennas, and
- select one of the different hypotheses with a higher narrowband reference signal receive power (NRSRP) than another based on the inferring the number of transmit antennas used by the at least one neighbor cell;
- and
- perform a neighbor cell search with measurement of NRSRP based on the determined information regarding the one or more transmission deployment mode parameters.
