Methods, systems, and devices related to related to digital wireless communication, and more specifically, to techniques related to pre-configure dedicated resources for data transmission. In one exemplary aspect, a method for wireless communication includes receiving a pre-configured transmission resource request from a terminal. The method also includes configuring a pre-configured transmission resource based on the pre-configured transmission resource request. In another exemplary embodiment, a method for wireless communication includes receiving a pre-configured transmission resource request from a terminal, wherein the pre-configured transmission resource request includes a medium access control (MAC) control element. The method also includes configuring a pre-configured transmission resource based on the pre-configured transmission resource request.
1. A method for wireless communication, comprising:
receiving, by a terminal, a first message including a pre-configured transmission resource configuration from a communication node, the first message further including a pre-configured transmission resource release instance including a counter configured to count a number of continuous inactivity of a pre-configured transmission resource associated with the pre-configured transmission resource configuration;
determining, by the terminal, that a timing advance (TA) is valid based on a Reference Signal Received Power (RSRP) change threshold and a TA validity timer; and
transmitting, by the terminal, a second message using a pre-configured transmission resource associated with the pre-configured transmission resource configuration based on the determining that the TA is valid, and
wherein the determining is further based on an RSRP change and the determining comprises:
setting an RSRP of a serving cell as a reference RSRP, in response to receiving, by the terminal, at least one of the pre-configured transmission resource configuration and a TA update indication; and
determining the RSRP change based on a difference between a measured RSRP value of the serving cell and the reference RSRP, and
wherein the method further comprises:
making, by the terminal, a comparison between the number of continuous inactivity of the pre-configured transmission resource and the pre-configured transmission resource release instance; and
releasing, by the terminal, the pre-configured transmission resource based on the comparison.

The method of claim 1 , wherein the determining determines that the TA is valid due to determining that (1) the TA validity timer is not included within the pre-configured transmission resource configuration and the RSRP change threshold is included within the pre-configured transmission resource configuration, and (2) the RSRP change does not exceed the RSRP change threshold.
6. The method of claim 1 , wherein the determining determines that the TA is invalid due to determining that (1) the TA validity timer is included within the pre-configured transmission resource configuration and that the RSRP change threshold is not included within the pre-configured transmission resource configuration, and (2) the TA validity timer expired.
7. The method of claim 1 , wherein the determining determines that the TA is valid due to determining that (1) the TA validity timer is included within the pre-configured transmission resource configuration and the RSRP change threshold is not included within the pre-configured transmission resource configuration, and (2) the TA validity timer has not expired.
8. The method of claim 1 , wherein the determining determines that the TA is invalid due to determining that (1) the RSRP change threshold and the TA validity timer are included within the pre-configured transmission resource configuration message and (2) the TA validity timer has expired or (2) the RSRP change exceeds the RSRP change threshold.
9. The method of claim 1 , wherein the counter is incremented based on an unsuccessful delivery of an uplink data message by the terminal using the pre-configured transmission resource at a pre-configured transmission resource time domain location included within the pre-configured transmission resource configuration.
10. The method of claim 1 , further comprising:
resetting, by the terminal, the counter based on successfully transmitting an uplink data message using the pre-configured transmission resource at a pre-configured transmission resource time domain location included within the pre-configured transmission resource configuration.
11. An apparatus for wireless communication comprising a processor that is configured to carry out a method comprising:
receiving a first message including a pre-configured transmission resource configuration from a communication node, the first message further including a pre-configured transmission resource release instance including a counter configured to count a number of continuous inactivity of a pre-configured transmission resource associated with the pre-configured transmission resource configuration;
determining that a timing advance (TA) is valid based on a Reference Signal Received Power (RSRP) change threshold and a TA validity timer; and
transmitting a second message using a pre-configured transmission resource associated with the pre-configured transmission resource configuration based on the determining that the TA is valid, and
wherein the determining is further based on an RSRP change and the determining comprises:
setting an RSRP of a serving cell as a reference RSRP, in response to receiving, by the apparatus, at least one of the pre-configured transmission resource configuration and a TA update indication; and
determining the RSRP change based on a difference between a measured RSRP value of the serving cell and the reference RSRP, and
wherein the method further comprises:
making a comparison between the number of continuous inactivity of the pre-configured transmission resource and the pre-configured transmission resource release instance; and
releasing the pre-configured transmission resource based on the comparison.
12. The apparatus of claim 11 , wherein the determining determines that the TA is valid based on another determination that the TA validity timer and the RSRP change threshold are not included within the pre-configured transmission resource configuration.
13. The apparatus of claim 11 , wherein the determining determines that the TA is valid due to determining that (1) the TA validity timer is not included within the pre-configured transmission resource configuration and the RSRP change threshold is included within the pre-configured transmission resource configuration, and (2) the RSRP change does not exceed the RSRP change threshold.
