Narrowband reference signals in non-anchor resource blocks
First Claim
1. A method for wireless communications by a user equipment (UE), comprising:
- deciding that a starting subframe for a paging occasion (PO), a random access response (RAR) transmission, or a single cell point to multipoint (SC-PTM) transmission will occur or has occurred;
determining occurrence of a narrowband reference signal (NRS) in a non-anchor resource block (RB) based on at least a length of a narrowband physical downlink control channel (NPDCCH) candidate and a minimum number of subframes, N, for transmission of NRSs after the end of the NPDCCH candidate; and
processing the NRS in at least the length plus N subframes after the PO, the RAR transmission, or the SC-PTM transmission.

Abstract
Certain aspects of the present disclosure generally relate to techniques for determining presence of narrowband reference signals (NRSs) in non-anchor physical resource blocks (PRBs). An exemplary method that may be performed by a user equipment (UE) includes deciding that a paging occasion (PO), a RAR transmission, or a SC-PTM transmission will occur or has occurred, determining occurrence of a narrowband reference signal (NRS) in a non-anchor resource block (RB) based on at least one of: the decision, one or more narrowband transmission parameters, or presence of one or more other transmissions in a same RB as the PO, the RAR transmission, or the SC-PTM transmission; and processing the NRS. Other aspects, embodiments, and features are also claimed and described.
