Radio terminal
A user equipment, apparatus, and method receives from a base station, for each bandwidth part of a plurality of bandwidth parts provided in a bandwidth of one carrier, information indicating a frequency location of the bandwidth part and information indicating a subcarrier spacing applied to the corresponding bandwidth part, and receives, from the base station, broadcast information including information on a special bandwidth part which the user equipment should use initially. A base station transmits to a user equipment, for each bandwidth part of a plurality of bandwidth parts provided in a bandwidth of one carrier, information indicating a frequency location of the bandwidth part and information indicating a subcarrier spacing applied to the corresponding bandwidth part, and transmits to the user equipment, broadcast information including information on a special bandwidth part which the user equipment should use initially.
Method and apparatus for user distribution to sub-bands in multiple access communications systems
A mechanism is presented for attributing users to one or more of a plurality of sub-bands in a multiple access communications system, wherein in an initial assignment phase, a first user is selected for a sub band, for example on the basis of a user priority. Users having complementary channel gains to that of the first user are identified, and then a second sub-band user maximizing a performance metric reflecting the achieved throughput, and/or fairness across users, is selected to accompany the first user on that sub-band. The initial assignment phase may terminate once all users have been assigned to a sub-band once. After the first phase is complete, the first user for each sub-band may be the user whose achieved total throughput is furthest from a target throughput defined for that user, wherein each user is assigned to the remaining sub-band to which no first user is currently attributed offering the highest channel gain for that user. Mechanisms for determining user priority, making provisional and definitive power allocations, and performance metrics are proposed.

The resource allocation method for a sidelink applied to the terminal includes: obtaining a mapping relationship between a specific target of the sidelink and a logical channel priority (LCP) restriction parameter of the sidelink; and performing resource allocation of the sidelink according to the mapping relationship; where the specific target comprises: a Quality of Service (QoS) parameter or a logical channel.
Uplink channel collision resolution for conditional media access control (MAC) layer based prioritization
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may detect a collision between a physical uplink control channel and a plurality of physical uplink shared channels (PUSCHs) with a corresponding plurality of media access control (MAC) priorities, selectively applying a MAC prioritization rule for processing the plurality of PUSCHs based at least in part on the corresponding plurality of MAC priorities and based at least in part on an effect of the plurality of MAC priorities on an uplink control information (UCI) multiplexing configuration for UCI multiplexing, and selectively transmitting at least one of the plurality of PUSCHs with the UCI based at least in part on a result of selectively applying the MAC prioritization rule. Numerous other aspects are provided.
RTA packet duplication in time and frequency
A wireless station and protocols for a wireless local area network (WLAN) to support real-time application (RTA) packets in setting up an unsolicited retry policy for RTA packets within a TXOP in which the station retransmits RTA packets in time and frequency domains without waiting for feedback. Setting up block acknowledgement (BA) agreements to receive feedback for adapting future packet transmissions. Dropping an RTA packet if a retry count for that packet exceeds the unsolicited retry limit, or a lifetime of that packet has expired. Supporting multi-link devices (MLDs) including access point multi-link devices (AP-MLDs) for performing simultaneous transmit/receive (STR), and non-access point multi-link device (non-AP MLDs) which are not configured for simultaneous transmit/receive (non-STR).
Interference-aware beamforming
Aspects of the disclosure relate to an interference-aware beamforming environment in which an AP controller can determine one or more beams of one or more APs to serve various STAs. For example, an AP can request that STA(s) provide one or more uplink pilot signals during different time slots. The AP can receive the uplink pilot signal(s) and determine, for each STA, the uplink beam quality of each transmit beam-receive beam pair over which an uplink pilot signal was received from the respective STA. The AP can use reciprocity to determine, for each STA, the downlink beam quality for various transmit beam-receive beam pairs. The AP can use the determined downlink beam quality to identify the best beam with which to serve various STAs. An AP controller can determine which downlink beam(s) an AP should use to serve a STA based on the downlink beams originally selected by the APs.
METHOD AND DEVICE FOR PRIORITIZATION OF LOGIC CHANNEL INCLUDING MAC CE HAVING PRIORITY VALUE
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to the present disclosure, a priority relative to data is configured by assigning a priority a MAC CE so that a MAC PDU may be transmitted according to the priority.
