1. A method of wireless communication by a user equipment (UE), comprising:
- determining, by the UE, whether the UE is located within a sub-region of a multicast broadcast single-frequency network (MBSFN) area based on one or more parameters;
receiving, by the UE, a service over broadcast based on a determination that the UE is located within the sub-region of the MBSFN area;
receiving, by the UE, the service over unicast based on a determination that the UE is not located within the sub-region, wherein the MBSFN area is smaller than a unicast area;
receiving, by the UE from a base station, a command to switch reception of the service over unicast to reception of the service over broadcast based on at least one of an MBSFN measurement by the UE or a unicast measurement by the UE when the UE receives the service over unicast; and
switching, by the UE, reception of the service over unicast to reception of the service over broadcast based on the command.

Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines whether the UE is located within a sub-region of an MBSFN area based on one or more parameters. The UE receives based on the determination a service over broadcast in the sub-region of the MBSFN area or over unicast outside the sub-region. In an aspect, the MBSFN area may be smaller than a unicast area. In an aspect, adaptive retransmission with a group NACK approach may be used to improve an SNR and reliability.

8. A user equipment (UE) for wireless communication, comprising:
-
a memory; and at least one processor coupled to the memory and configured to; determine whether the UE is located within a sub-region of a multicast broadcast single-frequency network (MBSFN) area based on one or more parameters; receive a service over broadcast based on a determination that the UE is located within the sub-region of the MBSFN area; receive the service over unicast based on a determination that the UE is not located within the sub-region, wherein the MBSFN area is smaller than a unicast area; receive, from a base station, a command to switch reception of the service over unicast to reception of the service over broadcast based on at least one of an MBSFN measurement by the UE or a unicast measurement by the UE when the UE receives the service over unicast; and switch reception of the service over unicast to reception of the service over broadcast based on the command. - View Dependent Claims (9, 10, 11, 12, 13, 14, 30)

15. A user equipment (UE) for wireless communication, comprising:
-
means for determining whether the UE is located within a sub-region of a multicast broadcast single-frequency network (MBSFN) area based on one or more parameters; means for receiving a service over broadcast based on a determination that the UE is located within the sub-region of the MBSFN area; means for receiving the service over unicast based on a determination that the UE is not located within the sub-region, wherein the MBSFN area is smaller than a unicast area; means for receiving, from a base station, a command to switch reception of the service over unicast to reception of the service over broadcast based on at least one of an MBSFN measurement by the UE or a unicast measurement by the UE when the UE receives the service over unicast; and means for switching reception of the service over unicast to reception of the service over broadcast based on the command. - View Dependent Claims (16, 17, 18, 19, 20, 21, 31)

22. A non-transitory, computer-readable medium storing computer executable code for wireless communication at a user equipment (UE), comprising code to:
-
determine whether the UE is located within a sub-region of a multicast broadcast single-frequency network (MBSFN) area based on one or more parameters; receive a service over broadcast based on a determination that the UE is located within the sub-region of the MBSFN area; receive the service over unicast based on a determination that the UE is not located within the sub-region, wherein the MBSFN area is smaller than a unicast area; receive, from a base station, a command to switch reception of the service over unicast to reception of the service over broadcast based on at least one of an MBSFN measurement by the UE or a unicast measurement by the UE when the UE receives the service over unicast; and switch reception of the service over unicast to reception of the service over broadcast based on the command. - View Dependent Claims (23, 24, 25, 26, 27, 28, 32)
