  • a persistent allocation is indicated with the HARQ process id for the case of asynchronous HARQ, or may be indicated by defining a special value for the RV or RSN.
  • the minimum number of HARQ processes is dictated by the minimum round trip time (RTT) of the HARQ 5 and fewer HARQ processes require faster processing at both the transmitter and receiver.

  • the HARQ process id is not necessarily transmitted (it can be associated instead, e.g., to system frame numbers).
  • the HARQ can also be asynchronous, meaning that the retransmissions may be delayed (e.g., if the channel is occupied by some other user).
  • the HARQ process id may be explicitly signaled. It can be signaled, e.g., on the L1/L2 control channel (PDCCH) together with other parameters.
  • PDCCH L1/L2 control channel
  • a current understanding is that a maximum of five or six HARQ processes will be required for LTE. If asynchronous HARQ is used, then the HARQ process id is sent on the Ll control channel. For a case where five or six HARQ processes can be used, a three bit process id is needed instead for identification purposes. For normal operation only the five or six, out of eight possible processes (those possible to be encoded by three bits), are used. During normal dynamic scheduling the HARQ process id is used to indicate which transmissions should be combined.
  • the new data indicator (NDI) and/or redundancy version (RV) or retransmission sequence number (RSN) are used to indicate a new transmission or a retransmission.

  • the eNB 12 configures one (or more) HARQ processes for a (semi-)persistent allocation and sends this information to the UE 10 via RRC signaling.
  • the RRC signaling may also indicate other parameters required for semi-persistent operation (e.g., the periodicity, i.e., how often the persistent allocation is in use).
  • the eNB 12 When the eNB 12 needs to allocate some resource to the UE 10 persistently (to be used by the UE 10, e.g., every 20 ms), it sends that allocation on the Ll control channel (which may employ an allocation table (AT)). The eNB 12 also sets the HARQ process id to (one of) the preconfigured value(s) and sets the RV or RSN to 0 (or any other predefined value which indicates initial transmission). The UE 10 receives the packet using the parameters and stores the parameters for future use.
  • the eNB 12 may simply send new packets to the UE 10 by using the persistently allocated resources and transport format, and without sending the Ll control channel, thereby conserving DL bandwidth and resources.
  • retransmissions are separately allocated using the Ll control channel (HARQ process id is the one pre-allocated for persistent allocation and RV or RSN indicates retransmission). Retransmissions may also be sent in persistently allocated resources without Ll control, while still using the embodiments of this invention. However, it may be preferred to schedule the retransmissions.
  • the UE 10 operation may be as follows:
  • the UE 10 receives via RRC signaling a configuration which configures one (or more) HARQ processes for (semi-)persistent allocation (together with other semi-persistent allocation parameters).
  • the UE 10 stores these parameters.
  • the UE 10 receives the packet on the associated data channel according to the parameters and stores the parameters for future use. If the reception is successful (e.g., the received data is successfully decoded) the UE 10 sends an ACK to the eNB 12, and if not successful the UE 10 sends a NAK and stores the data in an associated HARQ buffer 1OE.
  • the UE 10 If instead the Ll control is for the configured HARQ process and indicates retransmission (RV>0 or RSN>0), the UE 10 combines the packet on the associated data channel with the initial transmission and decodes the resulting combination (combined data). If the decoding is successful, the UE 10 sends the ACK, otherwise it sends the NAK and stores the combined data in the HARQ buffer 1OE.
  • the UE 10 receives the packet on the data channel (but does not store the parameters), and if it is a retransmission, the UE 10 combines the received data with an earlier transmission and decodes the combined data. If successful, the UE 10 sends the ACK, and if not successful the UE 10 sends the NAK and stores the data in the HARQ buffer 1OE.
  • the UE 10 attempts to decode using the stored parameters (provided that the semi-persistent allocation is valid in the current TTI). If decoding is successful, and the data was for the UE 10 (e.g., based on a UE-specific CRC on data channel), the UE 10 sends the ACK, and if not successful the UE 10 stores data in the HARQ buffer 1OE of the configured HARQ process but does not send the NAK.
  • the persistent allocation may be indicated with the special value for the RV or RSN, i.e., (at least) one value of the RV or RSN may be reserved to indicate that the allocation is persistent and should be stored for future use.
  • so forth If, for example, three bits are reserved for conveying the RSN value, then the largest possible value is seven.
  • the largest value of RSN (e.g., seven, assuming a three bit RSN field) may be reserved for this purpose.
  • the RSN is signaled with two bits, then the largest value for RSN is three and that value may then be used for indicating the persistent allocation. Similar to HSUPA, the RSN may indicate the redundancy version used in the transmission.
  • RSN or RV can be used for both synchronous and asynchronous HARQ, and with asynchronous HARQ, any HARQ process id can be used for persistent allocation.
  • the operation of the eNB 12 for the UL data transmission with (semi-)persistent allocation may be as follows:
  • the eNB 12 configures one RSN (or RV) for (semi-)persistent allocation and sends that information to the UE 10 via RRC signaling (the RRC signaling may also convey other parameters required for semi-persistent operation, such as the periodicity, i.e., how often the persistent allocation is in use). Alternatively the reserved RV or RSN is specified and eNB 12 then simply switches the feature on using RRC signaling.
  • RRC signaling may also convey other parameters required for semi-persistent operation, such as the periodicity, i.e., how often the persistent allocation is in use.
  • the reserved RV or RSN is specified and eNB 12 then simply switches the feature on using RRC signaling.
  • the eNB 12 When the eNB 12 allocates some resource to the UE 10 persistently (e.g., to be used by the UE, e.g., every 20 ms), it sends that allocation on the Ll control channel (e.g., by using the AT) and sets the RSN (or RV) to the specified/configured value.
  • the UE 10 transmits the packet using the allocated parameters and stores the parameters for future use.
  • the eNB 12 simply receives new packets from the UE 10 by using the persistently allocated resources and transport format without sending the UL allocation on the Ll control channel.
  • retransmissions are separately allocated using the Ll control channel, where the RSN (or RV) indicates the retransmission in a conventional manner.
  • Retransmissions can also be sent in persistently allocated resources without Ll control, while still using the exemplary embodiments of this invention, although scheduling of the retransmissions may be preferred.
  • the UE 10 operation may be as follows:
  • the UE 10 receives via RRC signaling a configuration which configures one RSN (or RV) for (semi-)persistent allocation (the signaling may also convey other semi-persistent allocation parameters) or, alternatively if RSN (or RV) to be used for semi-persistent allocation is specified in a standard, the UE 10 receives the RRC signaling that switches the feature on.

  • the third packet (DLP #3) in Figure 1 is also sent without L1/L2 control.
  • the fourth packet (DLP #4) is sent with L1/L2 control signaling since it may have a different format from the persistent allocation.

  • HARQ process id For a case where there are three bits reserved for the HARQ process id, in some networks all of these process ids may be used for dynamically scheduled H-ARQ (leaving no option for the persistent indication within the HARQ process id). In this case a reserved RSN/RV may be used (although it may increase the memory requirement compared to reserving one HARQ process for the persistent allocation). In another case, and in order to provide full flexibility to persistently allocated UEs 10 in terms of HARQ retransmission freedom, one may reserve a full HARQ process for persistent allocation (with full flexibility maintained in the RSN/RV domain).
