Streaming unicast services to multiple user equipment

1. A method comprising:

allocating, at a base station, a service identifier to a first user equipment in response to the first user equipment requesting a unicast service that the base station is already providing to a second user equipment using the service identifier;

transmitting, from the base station, content for the unicast service for reception by the first and second user equipment based on the service identifier, wherein transmitting the content for the unicast service comprises transmitting scheduling information on a first physical downlink control channel (PDCCH) using the service identifier, and wherein the scheduling information comprises scheduling information for the content transmitted over a first physical downlink shared channel (PDSCH); and

allocating a first temporary identifier to the first user equipment and a second temporary identifier to the second user equipment, wherein the first and second temporary identifiers are different.

2. The method of claim 1 , further comprising:

receiving an indication that at least one of the first user equipment and the second user equipment did not successfully receive a packet of the content transmitted over the first PDSCH; and

retransmitting the packet over at least one of the group consisting of a second PDSCH using the first temporary identifier and a third PDSCH using the second temporary identifier.

3. The method of claim 1 , further comprising:

transmitting at least one first packet of the content over the first PDSCH using the service identifier; and

transmitting at least one second packet of the content over a second PDSCH using the first temporary identifier, wherein the at least one second packet was transmitted over the first PDSCH using the service identifier prior to transmission of the at least one first packet of the content over the first PDSCH.

4. The method of claim 1 , further comprising:

storing a portion of the content of the unicast service for a predetermined time interval in response to receiving an instruction to store the portion of the content of the unicast service.

5. A method comprising:

allocating, at a base station, a service identifier to a first user equipment in response to the first user equipment requesting a unicast service that the base station is already providing to a second user equipment using the service identifier;

transmitting, from the base station, content for the unicast service for reception by the first and second user equipment based on the service identifier, wherein transmitting the content for the unicast service comprises transmitting scheduling information on a first physical downlink control channel (PDCCH) using the service identifier, and wherein the scheduling information comprises scheduling information for the content transmitted over a first physical downlink shared channel (PDSCH); and

cyclically transmitting a plurality of packets of the content over the first PDSCH using the service identifier so that the plurality of packets are retransmitted over the first PDCCH using the service identifier in response to completing transmission of the plurality of packets in a previous cycle.

6. The method of claim 5 , further comprising:

storing a portion of the content of the unicast service for a predetermined time interval in response to receiving an instruction to store the portion of the content of the unicast service.

7. A method comprising:

allocating, at a base station, a service identifier to a first user equipment in response to the first user equipment requesting a unicast service that the base station is already providing to a second user equipment using the service identifier,

transmitting, from the base station, content for the unicast service for reception by the first and second user equipment based on the service identifier;

scheduling transmission of the content based on at least one of the group consisting of a first channel condition associated with the first user equipment and a second channel condition associated with the second user equipment; and

increasing a priority associated with the unicast service in response to receiving a signal instructing the base station to allocate the service identifier to the first user equipment, and wherein scheduling the transmission of the content comprises scheduling the transmission of the content based on the priority associated with the unicast service.

8. The method of claim 7 , further comprising:

storing a portion of the content of the unicast service for a predetermined time interval in response to receiving an instruction to store the portion of the content of the unicast service.
