A method of wireless communication, comprising: determining, by a base station , a symbol timing drift between transmission points of base stations (105a-c) of a plurality of base stations in a coordinated multipoint, CoMP, group; signaling, from the base station 105d), a configuration instruction to one or more served user equipments, UEs (115a-b), to determine a downlink co-phasing value on a per-subband basis or to determine the downlink co-phasing value on a wideband basis based upon the symbol timing drift between transmission points of base stations (105a-c) of the plurality of base stations; receiving , at the base station , a downlink co-phasing value from the one or more UEs (115a-b), wherein the downlink co-phasing value represents a first phase difference between downlink phase synchronization reference signals, PSRS, received at each of the one or more served UEs (115a-b) from a pair of base stations (105a-b), wherein the base station is one of the plurality of base stations in the coordinated multipoint, CoMP, group serving the one or more served UEs (115a-b) using dynamic time division duplex, TDD, and wherein the base station performs backhaul communications with the plurality of base stations; receiving , at the base station , an uplink PSRS from the one or more served UEs (115a-b); computing , by the base station , an uplink co-phasing value based on a second phase difference between the uplink PSRS as received by a pair of base stations (105a-b) of the plurality of base stations; and applying , by the base station , a phase correction value for phase synchronization to communications by the plurality of base stations in the CoMP group, wherein the phase correction value corresponds to a difference between the downlink co-phasing value and the uplink co-phasing value. determining, by a base station , a symbol timing drift between transmission points of base stations (105a-c) of a plurality of base stations in a coordinated multipoint, CoMP, group; signaling, from the base station 105d), a configuration instruction to one or more served user equipments, UEs (115a-b), to determine a downlink co-phasing value on a per-subband basis or to determine the downlink co-phasing value on a wideband basis based upon the symbol timing drift between transmission points of base stations (105a-c) of the plurality of base stations; receiving , at the base station , a downlink co-phasing value from the one or more UEs (115a-b), wherein the downlink co-phasing value represents a first phase difference between downlink phase synchronization reference signals, PSRS, received at each of the one or more served UEs (115a-b) from a pair of base stations (105a-b), wherein the base station is one of the plurality of base stations in the coordinated multipoint, CoMP, group serving the one or more served UEs (115a-b) using dynamic time division duplex, TDD, and wherein the base station performs backhaul communications with the plurality of base stations; receiving , at the base station , an uplink PSRS from the one or more served UEs (115a-b); computing , by the base station , an uplink co-phasing value based on a second phase difference between the uplink PSRS as received by a pair of base stations (105a-b) of the plurality of base stations; and applying , by the base station , a phase correction value for phase synchronization to communications by the plurality of base stations in the CoMP group, wherein the phase correction value corresponds to a difference between the downlink co-phasing value and the uplink co-phasing value. <EOS>
