Abstract:
A wireless device may select, based on a first group of search space sets for monitoring control resource sets (coresets) and a second group of search space sets for monitoring the coresets, reference signals, associated with the first group of search space sets, for link monitoring in both a first mode and a second mode. In the first mode, the first group of search space sets are monitored and the second group of search space sets are unmonitored. In the second mode, the first group of search space sets are unmonitored and the second group of search space sets are monitored. The wireless device may measure, both in the first mode and the second mode, the reference signals for the link monitoring.

International Classification:
H04W 74/08
H04W 72/08
H04W 72/04
H04W 76/27
H04W 74/00
Abstract:
A wireless device receives at least one power threshold for selecting one of a first uplink carrier or a second uplink carrier of a cell. The wireless device selects, based on the at least one power threshold and a speed of the wireless device, one of the first uplink carrier and the second uplink carrier as a selected uplink carrier. The wireless device transmits a random access preamble via the selected uplink carrier.

Transmission Power Control For Beam Failure Recovery Requests

17/860594
Inventors:
- Philadelphia PA, US
Esmael Hejazi Dinan - McLean VA, US
Alireza Babaei - Fairfax VA, US
Hyoungsuk Jeon - Centreville VA, US
Kyungmin Park - Vienna VA, US
International Classification:
H04W 76/18
H04B 7/06
H04B 17/10
H04L 5/00
H04W 52/50
H04W 52/14
H04W 52/42
Abstract:
Systems, apparatuses, and methods are described for wireless communications. A base station may transmit indications of target received powers for a random access procedure and a beam failure recovery procedure. A wireless device may transmit a random access preamble and a beam failure recovery preamble using different transmission powers based on the indications of target received powers.

Transmission Information For A Configured Periodic Grant Of A Wireless Device

View page
US Patent:
20220385404, Dec 1, 2022
Filed:
Aug 2, 2022
Appl. No.:
17/879342
Inventors:
- Suwon-si, KR
Esmael DINAN - McLean VA, US
Kyungmin PARK - Vienna VA, US
Alireza BABAEI - Fairfax VA, US
International Classification:
H04L 1/16
H04W 72/14
H04L 5/00
H04W 72/04
Abstract:
A wireless device receives, from a base station, at least one first message comprising a first periodicity of resources of a configured periodic grant of a first type. A request for transmission information associated with the configured periodic grant is received. A response is transmitted. The response comprises: a first value based on a number of transmissions via the resources the configured periodic grant; and a second value based on a number of times that the wireless device received no corresponding acknowledgement from the base station in response to the transmissions.

Semi-Persistent Scheduling Release

View page
US Patent:
20220385537, Dec 1, 2022
Filed:
Aug 9, 2022
Appl. No.:
17/884539
Inventors:
- Fairfax VA, US
Alireza Babaei - Fairfax VA, US
Assignee:
PanPsy Technologies, LLC - Fairfax VA
International Classification:
H04L 41/0896
H04L 41/0803
H04L 5/00
H04L 1/18
H04W 72/12
Abstract:
A base station transmits RRC message(s) comprising a first configuration parameter of a first SPS configuration, a second configuration parameter of a second SPS configuration, and a third configuration parameter. The first configuration parameter may indicate a first HARQ codebook identifier. The second configuration parameter may indicate a second HARQ codebook identifier. The second HARQ codebook identifier may be the same as the first HARQ codebook identifier. The third configuration parameter may indicate a state that is mapped to the first SPS configuration and the second SPS configuration. A DCI may be transmitted. A value of bit(s) of a HARQ process number field of the DCI may indicate the state. The DCI may indicate deactivation of the first SPS configuration and the second SPS configuration. An acknowledgement may be received.

Validation Of A Dci Format

US Patent:
20220386358, Dec 1, 2022
Filed:
Aug 9, 2022
Appl. No.:
17/884046
Inventors:
- Fairfax VA, US
Alireza Babaei - Fairfax VA, US
Assignee:
PanPsy Technologies, LLC - Fairfax VA
International Classification:
H04W 72/12
H04L 1/18
H04W 72/14
H04W 76/20
H04W 76/30
Abstract:
A base station may transmit a DCI comprising a HARQ process number field, comprising first bit(s), and an RV field comprising second bit(s). The base station may receive a TB in response to validation of the DCI. The validation may be based on the second bit(s). The validation may be based on comparing the first bit(s) with a first sequence of bit(s), determined using a first configuration parameter, in response to the first bit(s) not indicating a configuration index and the DCI having a first format. The validation may not be based on comparing the first bit(s) with the first sequence in response to the DCI having a second format.

Signaling For Cancellation Of Transmission On An Uplink Carrier

US Patent:
20220386412, Dec 1, 2022
Filed:
Aug 10, 2022
Appl. No.:
17/884649
Inventors:
- Fairfax VA, US
Alireza Babaei - Fairfax VA, US
Assignee:
PanPsy Technologies, LLC - Fairfax VA
International Classification:
H04W 76/36
H04W 72/04
H04W 76/11
H04W 24/08
H04W 72/12
Abstract:
A base station transmits configuration parameters indicating a first position and a second position. The first position may be in a first number of bit. The second position may be in a second number of bit. The first number of bit and the second number of bit may be based on a payload size. The base station may transmit cancellation indications comprising a first cancellation indication. The first cancellation indication may indicate cancellation of a scheduled transmission. The first cancelation indication may be based on the first position when the scheduled transmission is for a normal carrier and may be based on the second position when the scheduled transmission is for a supplementary carrier.
