Reserved resource pool assisted access resource selection for small data transmission
First Claim
1. A method for wireless communication, comprising:
- capturing, by an internet of everything (IOE) device, information data;
transmitting, from the IOE device to a wireless communications device, a first set of data of the captured information data using a first access resource selected from a common pool of access resources as part of a grant-less transmission;
determining, by the IOE device, to switch from the common pool of access resources to a reserved access pool for transmitting a second set of data of the captured information data based on a metric associated with a channel condition, the second set of data including remaining information data to the first set of data of the captured information data;
requesting, by the IOE device, the wireless communications device to provide a second access resource from the reserved access pool for transmitting the second set of data of the captured information data based on the determining; and
transmitting, by the IOE device, the second set of data of the captured information data to the wireless communications device using the second access resource from the reserved access pool after switching from the common pool of access resources to the second access resource,wherein the common pool of access resources includes a smaller amount of access resources than the reserved access pool.

Abstract
Wireless communications systems and methods related to the reduction in a probability of collision for grant-less transmissions from internet of everything (IOE) devices while not increasing search complexity at a base station are disclosed. An IOE device randomly selects a first access resource from a common pool that the base station searches to initiate a transmission. If a metric associated with the data transmission is predicted to exceed a threshold, the IOE device also requests a second access resource from a reserved access pool from the base station, that the base station does not search. The IOE includes the request in the data transmission. The base station and the IOE device switch to the second access resource after the base station identifies an available resource from the reserved access pool and the IOE device completes the data transmission using the second access resource.

9. A method for wireless communication, comprising:
-
searching, by a first wireless communications device, a common pool of access resources to recover a first set of data of information data captured by and received from an internet of everything (IOE) device using a first access resource selected from the common pool of access resources as part of a grant-less transmission; receiving, at the first wireless communications device using the first access resource, a request from the IOE device to provide a second access resource selected from a reserved access pool to the IOE device after receiving the first set of data based on a metric associated with a channel condition; transmitting an identification of the second access resource selected from the reserved access pool to the IOE device; and switching from the common pool of access resources to the second access resource of the reserved access pool to recover a second set of data of the captured information data from the IOE device without searching the reserved access pool, the second set of data including remaining information data to the first set of data of the captured information data, wherein the common pool of access resources includes a smaller amount of access resources than the reserved access pool. - View Dependent Claims (10, 11, 12, 13, 14)

15. An internet of everything (IOE) device, comprising:
-
a sensor configured to capture information data; a processor configured to; select a first access resource from a common pool of access resources for transmitting a first set of data of the captured information data to a wireless communication device as part of a grant-less transmission to the wireless communications device; and determine to switch from the common pool of access resources to a reserved access pool for transmitting a second set of data of the captured information data based on a metric associated with a channel condition, the second set of data including remaining information data to the first set of data of the captured information data; request the wireless communications device to provide a second access resource from a reserved access pool based on the determination; and a transceiver configured to; transmit the first set of data of the captured information data to the wireless communications device using the first access resource, wherein the first set of data includes the request for the second access resource in response to the determination; and transmit the second set of data of the captured information data to the wireless communications device using the second access resource from the reserved access pool after switching from the common pool of access resources to the second access resource, wherein the common pool of access resources includes a smaller amount of access resources than the reserved access pool. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 30)
