System and method for single carrier optimization for evolved multimedia broadcast multicast service

摘要

Techniques are provided for single carrier optimization. For example, there is provided a method that involves, in a subframe of a radio spectrum, allocating a first set of resource elements (REs) for multimedia broadcast over a single frequency network (MBSFN) transmissions, each symbol corresponding to each RE of the first set having a first cyclic prefix (CP) type. The method may involve allocating a second set of REs for unicast transmissions, each symbol corresponding to each RE of second set having a second CP type. The method may involve determining whether the first CP type and the second CP type are the same. The method may involve, in response to the first CP type and the second CP type being the same, combining the MBSFN transmissions and the unicast transmissions in the subframe according to the allocated first and second sets of REs.

1. A method for single carrier optimization for evolved Multimedia Broadcast Multicast Service (eMBMS) by at least one network entity, comprising:
in a subframe of a radio spectrum, allocating a first set of resource elements (REs) for multimedia broadcast over a single frequency network (MBSFN) transmissions, each symbol corresponding to each RE of the first set having a first cyclic prefix (CP) type; allocating a second set of REs for unicast transmissions, each symbol corresponding to each RE of the second set having a second CP type; determining whether the first CP type and the second CP type are the same; and in response to the first CP type and the second CP type being the same, combining the MBSFN transmissions and the unicast transmissions in the subframe according to the allocated first and second sets of REs, wherein combining the MBSFN transmissions and the unicast transmissions comprises sending MBSFN reference signals on symbols devoid of unicast cell-specific reference signals (CRS).
