Uplink transmissions for type 2 relay
A method for providing user agent data. The method includes an access node receiving an indicator sent from a relay node as an indication that the relay node has received data from the user agent.
1. An access node in a wireless telecommunications network, the access node comprising:
a memory; and
a processor coupled to the memory and configured to:
make a first determination that a first user agent (UA) is to communicate indirectly with the access node through a relay node;
make a second determination that a second UA is to communicate directly with the access node; and
make a third determination of an allocation of reserved subframes to the first UA and the second UA based on the first determination and the second determination, wherein the allocation allocates at least one of the reserved subframes to the first UA and at least one remaining subframe to the second UA.
2. The access node of claim 1 , wherein the processor is further configured to:
reserve a group of reserved subframes;
select at least one subframe from the group of reserved subframes for the first UA; and
select at least one remaining subframe from the group of reserved subframes for the second UA.
3. The access node of claim 1 , wherein the processor is further configured to:
reserve a group of reserved subframes;
dynamically select at least one subframe from the group of reserved subframes for the first UA as required by the first UA; and
select at least one remaining subframe from the group of reserved subframes for the second UA.
4. The access node of claim 1 , wherein the processor is further configured to:
firstly reserve reserved subframes;
secondly select a group of the reserved subframes for the first UA;
thirdly select at least one remaining reserved subframe for the second UA;
fourthly determine that the first UA does not require all of the reserved subframes in the group; and
fifthly reserve at least one of the reserved subframes in the group for the second UA.
5. The access node of claim 1 , further comprising a transmitter coupled to the processor and configured to transmit to the relay node an indication of the allocation before the first UA is to transmit data to the relay node.
6. The access node of claim 1 , wherein the processor is further configured to allocate the resources when the relay node is a type 2 relay node.
7. The access node of claim 6 , wherein the processor is further configured to not allocate the resources when the relay node is a type 1 relay node or a type 3 relay node.
8. The access node of claim 1 , wherein the processor is further configured to enable non-adaptive synchronous retransmission in the relay node based on the first determination.
9. The access node of claim 8 , further comprising a transmitter coupled to the processor and configured to transmit to the relay node an indication of the non-adaptive synchronous retransmission using one of radio resource control (RRC) signaling, medium access control (MAC) control elements, or physical downlink control channel (PDCCH) signaling.
10. The access node of claim 9 , wherein the PDCCH signaling comprises a one-bit indicator instructing the relay node to turn on or turn off the non-adaptive synchronous retransmission.
11. A method implemented in a wireless telecommunications network, the method comprising:
making a first determination that a first user agent (UA) is to communicate through a relay node;
making a second determination that a second UA is to communicate without the relay node;
making a third determination of an allocation of reserved subframes to the first UA and the second UA based on the first determination and the second determination, wherein the allocation allocates at least one of the reserved subframes to the first UA and at least one remaining subframe to the second UA.
12. The method of claim 11 , further comprising:
reserving a group of reserved subframes;
selecting at least one subframe from the group of reserved subframes for the first UA; and
selecting at least one remaining subframe from the group of reserved subframes for the second UA.
13. The method of claim 11 , further comprising
reserving a group of reserved subframes;
dynamically selecting at least one subframe from the group of reserved subframes for the first UA as required by the first UA; and
selecting at least one remaining subframe from the group of reserved subframes for the second UA.
14. The method of claim 11 , further comprising transmitting to the relay node an indication of the allocation before the first UA is to transmit data to the relay node.
15. The method of claim 11 , further comprising enabling non-adaptive synchronous retransmission in the relay node based on the first determination.
16. The method of claim 15 , further comprising transmitting to the relay node an indication of the non-adaptive synchronous retransmission using one of radio resource control (RRC) signaling, medium access control (MAC) control elements, or physical downlink control channel (PDCCH) signaling.
17. The method of claim 16 , wherein the PDCCH signaling comprises a one-bit indicator instructing the relay node to turn on or turn off the non-adaptive synchronous retransmission.
18. A relay node in a wireless telecommunications network, the relay node comprising:
a memory;
a processor coupled to the memory and configured to determine an association of the relay node with a first user agent (UA); and
a receiver coupled to the processor and configured to receive from an access node a first indication of an allocation of reserved subframes,
wherein the allocation is based on the association and based on a second UA not being associated with the relay node, and
wherein the allocation allocates at least one of the reserved subframes to the first UA and at least one remaining subframe to the second UA.
19. The relay node of claim 18 , wherein the receiver is further configured to receive from the access node a second indication of non-adaptive synchronous retransmission via one of radio resource control (RRC) signaling, medium access control (MAC) control elements, or physical downlink control channel (PDCCH) signaling.
20. The relay node of claim 19 , wherein, when the PDCCH signaling is used, the receiver is further configured to receive a one-bit indicator instructing the relay node to turn on or turn off the non-adaptive synchronous retransmission.
