Semi-persistent scheduling in a wireless device and network
A wireless device receives at least one message. The at least one message comprises an uplink semi persistent scheduling (SPS) radio network temporary identifier (RNTI), and a sequence of at least one uplink SPS information element (IE). An uplink SPS IE of the sequence comprises: at least one uplink SPS configuration parameter comprising an uplink SPS interval, and an SPS configuration index for the at least one uplink SPS configuration parameter. A downlink control information (DCI) corresponding to the uplink SPS RNTI may be received. The DCI comprises a first SPS configuration index of one of the at least one uplink SPS IE. At least one transport block may be transmitted employing at least one first uplink SPS configuration parameter corresponding to the first SPS configuration index.
1. A method comprising:
receiving, by a wireless device, at least one radio resource control message comprising uplink periodic resource allocation configuration parameters indicating a hybrid automatic repeat request (HARQ) process identifier offset;
determining a HARQ process identifier for a current transmission time interval based on the HARQ process identifier offset; and
transmitting a transport block associated with a HARQ process identified by the HARQ process identifier.
2. The method of claim 1 , wherein the determining further comprises determining the HARQ process identifier for the current transmission time interval as a sum of the HARQ process identifier offset and a result of an initial value modulo a number of uplink HARQ processes.
3. The method of claim 2 , wherein the initial value is equal to the floor of the current transmission time interval divided by an uplink interval.
4. The method of claim 1 , wherein the uplink periodic resource allocation configuration parameters further indicate the number of uplink HARQ processes and the uplink interval.
5. A wireless device, comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive at least one radio resource control message comprising uplink periodic resource allocation configuration parameters indicating a hybrid automatic repeat request (HARQ) process identifier offset;
determine a HARQ process identifier for a current transmission time interval based on the HARQ process identifier offset; and
transmit a transport block associated with a HARQ process identified by the HARQ process identifier.
6. The wireless device of claim 5 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to determine the HARQ process identifier for the current transmission time interval as a sum of the HARQ process identifier offset and a result of an initial value modulo a number of uplink HARQ processes.
7. The wireless device of claim 6 , wherein the initial value is equal to the floor of the current transmission time interval divided by an uplink interval.
8. The wireless device of claim 5 , wherein the uplink periodic resource allocation configuration parameters further indicate the number of uplink HARQ processes and the uplink interval.
9. A method comprising:
transmitting, by a base station, at least one radio resource control message comprising uplink periodic resource allocation configuration parameters indicating a hybrid automatic repeat request (HARQ) process identifier offset;
determining a HARQ process identifier for a current transmission time interval based on the HARQ process identifier offset; and
receiving a transport block associated with a HARQ process identified by the HARQ process identifier.
10. The method of claim 9 , wherein the determining further comprises determining the HARQ process identifier for the current transmission time interval as a sum of the HARQ process identifier offset and a result of an initial value modulo a number of uplink HARQ processes.
11. The method of claim 10 , wherein the initial value is equal to the floor of the current transmission time interval divided by an uplink interval.
12. The method of claim 9 , wherein the uplink periodic resource allocation configuration parameters further indicate the number of uplink HARQ processes and the uplink interval.
13. A base station, comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to perform the actions of the method of claim 9 .
