RESERVED RESOURCE POOL ASSISTED ACCESS RESOURCE SELECTION FOR SMALL DATA TRANSMISSION
First Claim
1. A method for wireless communication, comprising:
- transmitting, from a first wireless communications device to a second wireless communications device, a first set of data using a first access resource selected from a common pool of access resources as part of a grant-less transmission;
requesting, by the first wireless communications device, the second wireless communications device to provide a second access resource from a reserved access pool based on a metric; and
transmitting, by the first wireless communications device, a second set of data to the second wireless communications device using the second access resource after transitioning to the second access resource.

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 received from a second wireless communications 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, a request from the second wireless communications device to provide a second access resource selected from a reserved access pool to the second wireless communications device; transmitting an identification of the second access resource selected from the reserved access pool to the second wireless communications device; and switching to the second access resource to recover a second set of data from the second wireless communications device without searching the reserved access pool. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A first wireless communications device, comprising:
-
a processor configured to select a first access resource from a common pool of access resources as part of a grant-less transmission to a second wireless communications device and, based on a metric, request the second wireless communications device to provide a second access resource from a reserved access pool; and a transceiver configured to transmit a first set of data to the second 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, the transceiver being further configured to transmit a second set of data to the second wireless communications device using the second access resource. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A first wireless communications device, comprising:
-
a transceiver configured to receive a first set of data from a second wireless communications device, wherein the first set of data is transmitted using a first access resource selected from a common pool of access resources as part of a grant-less transmission from the second wireless communications device; a resource coordinator configured to search the common pool of access resources to recover the first set of data received from the second wireless communications device, wherein the transceiver is further configured to receive a request from the second wireless communications device to provide a second access resource selected from a reserved access pool and transmit an identification of the second access resource selected from the reserved access pool to the second wireless communications device; and a processor configured to switch the transceiver to the second access resource to recover a second set of data from the second wireless communications device without searching the reserved access pool. - View Dependent Claims (25, 26, 27, 28, 29, 30)
