Stopping Ongoing Random Access Procedure for Triggered Scheduling Request
A method can include receiving, by a wireless device, one or more configuration parameters for a timing advance (TA) reporting procedure. The one or more configuration parameters can include a first timing advance threshold for a TA reporting based on an offset between a current timing advance value and a last reported timing advance value. The method can also include triggering the TA reporting procedure based on a condition for the first timing advance threshold being satisfied. The method can further include triggering a scheduling request (SR), based on the triggering the TA reporting procedure. The method can additionally include transmitting a TA reporting information via one or more uplink shared channel (UL-SCH) resources. The method can also include, in response to the transmitting the TA reporting information, stopping an ongoing random access procedure for the triggered SR.
1 . 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 one or more configuration parameters for a timing advance (TA) reporting procedure, wherein the one or more configuration parameters comprise a first timing advance threshold for a TA reporting based on an offset between a current timing advance value and a last reported timing advance value;
trigger the TA reporting procedure based on a condition for the first timing advance threshold being satisfied;
trigger a scheduling request (SR), based on the triggering the TA reporting procedure;
transmit a TA reporting information via one or more uplink shared channel (UL-SCH) resources; and
in response to the transmitting the TA reporting information, stop an ongoing random access procedure for the triggered SR, wherein:
the SR has no valid physical uplink control channel (PUCCH) resource; and
the one or more UL-SCH resources are not associated with the ongoing random access procedure.
2 . The wireless device of claim 1 , wherein the instructions further cause the wireless device to initiate a random access procedure based on the triggering the SR, wherein the ongoing random access procedure is the initiated random access procedure.
3 . The wireless device of claim 2 , wherein the instructions further cause the wireless device to cancel the triggered SR based on the initiating the random access procedure.
4 . The wireless device of claim 3 , wherein the instructions further cause the wireless device to:
start an SR prohibit timer based on the triggering the TA reporting procedure; and
stop the SR prohibit timer based on the canceling the triggered SR.
5 . The wireless device of claim 4 , wherein the one or more configuration parameters indicate a Type 1 configured grant or a Type 2 configured grant, wherein the one or more UL-SCH resources are indicated by at least one of the Type 1 configured grant or the Type 2 configured grant.
6 . The wireless device of claim 5 , wherein a first UL-SCH resource associated with the ongoing random access procedure is indicated by a random access response (RAR) of the ongoing random access procedure.
7 . The wireless device of claim 6 , wherein a second UL-SCH resource associated with the ongoing random access procedure is for transmission of a message A (MSGA) of the ongoing random access procedure.
8 . The wireless device of claim 7 , wherein the instructions further cause the wireless device to receive a first downlink control information (DCI) indicating a dynamic grant.
9 . The wireless device of claim 8 , wherein the one or more UL-SCH resources are based on the dynamic grant.
10 . The wireless device of claim 9 , wherein the DCI schedules a transmission or a retransmission of a message 3 of the ongoing random access procedure using the one or more UL-SCH resources, wherein the DCI is scrambled by a temporary cell radio network temporary identifier (TC-RNTI).
11 . A method, comprising:
receiving, by a wireless device, one or more configuration parameters for a timing advance (TA) reporting procedure, wherein the one or more configuration parameters comprise a first timing advance threshold for a TA reporting based on an offset between a current timing advance value and a last reported timing advance value;
triggering the TA reporting procedure based on a condition for the first timing advance threshold being satisfied;
triggering a scheduling request (SR), based on the triggering the TA reporting procedure;
transmitting a TA reporting information via one or more uplink shared channel (UL-SCH) resources; and
in response to the transmitting the TA reporting information, stopping an ongoing random access procedure for the triggered SR, wherein:
the SR has no valid physical uplink control channel (PUCCH) resource; and
the one or more UL-SCH resources are not associated with the ongoing random access procedure.
12 . The method of claim 11 , further comprising initiating a random access procedure based on the triggering the SR, wherein the ongoing random access procedure is the initiated random access procedure.
13 . The method of claim 12 , further comprising canceling the triggered SR based on the initiating the random access procedure.
14 . The method of claim 13 , further comprising:
starting an SR prohibit timer based on the triggering the TA reporting procedure; and
stopping the SR prohibit timer based on the canceling the triggered SR.
15 . The method of claim 14 , wherein the one or more configuration parameters indicate a Type 1 configured grant or a Type 2 configured grant, wherein the one or more UL-SCH resources are indicated by at least one of the Type 1 configured grant or the Type 2 configured grant.
16 . The method of claim 15 , wherein a first UL-SCH resource associated with the ongoing random access procedure is indicated by a random access response (RAR) of the ongoing random access procedure.
17 . The method of claim 16 , wherein a second UL-SCH resource associated with the ongoing random access procedure is for transmission of a message A (MSGA) of the ongoing random access procedure.
18 . The method of claim 17 , further comprising receiving a first downlink control information (DCI) indicating a dynamic grant.
19 . The method of claim 18 , wherein the one or more UL-SCH resources are based on the dynamic grant.
20 . The method of claim 19 , wherein the DCI schedules a transmission or a retransmission of a message 3 of the ongoing random access procedure using the one or more UL-SCH resources, wherein the DCI is scrambled by a temporary cell radio network temporary identifier (TC-RNTI).
