A method for wireless communications, comprising: receiving, at a user equipment, UE, from a serving access point, a reference signal configuration specifying a periodicity at which to transmit reference signals over at least one symbol in a plurality of subframes; transmitting one or more uplink reference signal transmissions by the UE to the serving access point based on the received reference signal configuration; receiving, at the UE from the serving access point, downlink control information having a dynamic resource allocation indicator; receiving, at the UE from the serving access point, an uplink resource grant, the uplink resource grant indicating resources for uplink data communications in the at least one symbol based on the dynamic resource allocation indicator indicating that the at least one symbol in the at least one of the plurality of subframes is for the uplink data communications; determining, at the UE, that the dynamic resource allocation indicator indicates to override, for a period of time corresponding to the uplink resource grant, the reference signal configuration in at least one of the plurality of subframes; and transmitting, by the UE to the serving access point and based at least in part on the determination that the dynamic resource allocation indicator indicates to override the reference signal configuration in the at least one of the plurality of subframes, uplink data communications over the at least one symbol in the at least one of the plurality of subframes; wherein: transmitting the uplink data communications comprises transmitting the uplink data communications over the at least one symbol and remaining symbols in the at least one of the plurality of subframes, or the period of time corresponding to an uplink resource grant corresponds to a plurality of subframes, and wherein transmitting the uplink data communications comprises transmitting the uplink data communications in the plurality of subframes. receiving, at a user equipment, UE, from a serving access point, a reference signal configuration specifying a periodicity at which to transmit reference signals over at least one symbol in a plurality of subframes; transmitting one or more uplink reference signal transmissions by the UE to the serving access point based on the received reference signal configuration; receiving, at the UE from the serving access point, downlink control information having a dynamic resource allocation indicator; receiving, at the UE from the serving access point, an uplink resource grant, the uplink resource grant indicating resources for uplink data communications in the at least one symbol based on the dynamic resource allocation indicator indicating that the at least one symbol in the at least one of the plurality of subframes is for the uplink data communications; determining, at the UE, that the dynamic resource allocation indicator indicates to override, for a period of time corresponding to the uplink resource grant, the reference signal configuration in at least one of the plurality of subframes; and transmitting, by the UE to the serving access point and based at least in part on the determination that the dynamic resource allocation indicator indicates to override the reference signal configuration in the at least one of the plurality of subframes, uplink data communications over the at least one symbol in the at least one of the plurality of subframes; wherein: transmitting the uplink data communications comprises transmitting the uplink data communications over the at least one symbol and remaining symbols in the at least one of the plurality of subframes, or the period of time corresponding to an uplink resource grant corresponds to a plurality of subframes, and wherein transmitting the uplink data communications comprises transmitting the uplink data communications in the plurality of subframes. transmitting the uplink data communications comprises transmitting the uplink data communications over the at least one symbol and remaining symbols in the at least one of the plurality of subframes, or the period of time corresponding to an uplink resource grant corresponds to a plurality of subframes, and wherein transmitting the uplink data communications comprises transmitting the uplink data communications in the plurality of subframes.
