Signal Monitoring Method and Apparatus
A signal monitoring method is provided: If the terminal device determines, based on a message received or sent in a first time unit, that the terminal device is not in a DRX active time in a second time unit, the terminal device monitors the power saving signal in the second time unit. The terminal device determines, based on the power saving signal, whether to monitor a PDCCH in a first time interval. The first time unit is located before the second time unit, and is separated from the second time unit by M third time units. M is an integer greater than or equal to 1. The embodiments of this application are applied to a mobile communications system such as 5G NR.
APPARATUSES AND METHODS FOR DISCONTINUOUS RECEPTION (DRX) SUPPORT IN SIDELINK COMMUNICATION
A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from one or more peer UEs. The controller determines a Sidelink (SL) Discontinuous Reception (DRX) configuration set, and applies the SL DRX configuration set to enable a DRX operation for SL communications with the peer UEs via the wireless transceiver; wherein the SL DRX configuration set is determined based on one of the following: one or more types of one or more SL services which the UE is participating with the peer UEs; one or more SL DRX configurations received from the peer UEs; and control information received from a Base Station (BS).
Methods and Apparatuses for Paging
Methods and apparatuses for paging are disclosed. According to an embodiment, a paging related entity obtains first information about a probability at which each of at least one terminal device is paged at a paging occasion (PO). The paging related entity obtains second information about a first power consumption and a second power consumption spent by each of the at least one terminal device for detecting a wake up signal (WUS) and a paging message respectively. The paging related entity determines, for multiple applicable WUS to PO mapping parameters, corresponding power consumptions spent by the at least one terminal device in a paging time window (PTW), based on the first and second information. The paging related entity determines, as a target WUS to PO mapping parameter to be applied to the at least one terminal device, one of the multiple applicable WUS to PO mapping parameters corresponding to a lowest power consumption in a PTW.
METHODS AND APPARATUSES FOR CONTROL OF CROSS-BANDWIDTH PART (BWP) WAKE UP SIGNALING (WUS) ACTIVATION
Systems, methods, apparatuses, and computer program products for control of cross-bandwidth part (BWP) wake up signaling (WUS) activation are provided. One method includes configuring a user equipment with a wake up signaling (WUS) bandwidth part (BWP) and a plurality of non-wake up signaling (WUS) bandwidth part (BWPs), and transmitting a wake up signaling (WUS) indication.
SIDELINK DISCONTINUOUS RECEPTION MANAGEMENT FOR GROUPCAST AND BROADCAST
Apparatus, methods, and computer-readable media for sidelink discontinuous reception (DRX) management for groupcast and broadcast are disclosed herein. A transmitter user equipment (UE) may determine one or more adjustments to a sidelink DRX configuration or DRX operation based on one or more factors of the transmitter UE, and transmit, to a receiver UE over a sidelink channel, during at least a portion of a sidelink DRX active duration, a first message comprising an indication of the one or more adjustments to the sidelink DRX configuration or DRX operation. A receiver UE may receive, from a transmitter UE sent to multiple UEs over a sidelink channel, during a portion of a sidelink DRX active duration, a first message comprising an indication of one or more first adjustments to a sidelink DRX configuration or DRX operation, and determine whether to respond to the indication based on parameters of the receiver UE.
Method and apparatus for transmitting wakeup packet in wireless LAN system
A method and an apparatus for transmitting a wakeup packet in a wireless LAN system are proposed. Specifically, a transmitter generates a wakeup packet by applying an OOK scheme. The transmitter transmits the wakeup packet to a receiver via an 80 MHz channel. The 80 MHz channel includes first to fourth subchannels. If some of the first to fourth subchannels are busy or there are no pending wakeup packets for the receiver in some of the subchannels, some of the subchannels are punctured. The wakeup packet is transmitted via the remaining subchannels of the first to fourth subchannels. Each of the first to fourth subchannels is a 20 MHz channel.
Reducing Power Consumption of a User Equipment Configured for Discontinuous Reception
An access node (110) configures a User Equipment, UE (105), with a power saving monitoring pattern, and subsequently transmits a power saving signal configured to switch the UE (105) from monitoring a downlink in accordance with a connected mode discontinuous reception, C-DRX, monitoring pattern to monitoring the downlink in accordance with the power saving monitoring pattern. For each of the monitoring patterns, monitoring the down-link in accordance with the monitoring pattern comprises monitoring the down-link only when a monitoring opportunity of the monitoring pattern is concurrent with a scheduled active interval of a C-DRX configuration of the UE (105). For any C-DRX cycle of the C-DRX configuration, the monitoring of the downlink in accordance with the power saving monitoring pattern has a shorter monitoring duration than the monitoring of the downlink in accordance with the C-DRX monitoring pattern. The UE (105) correspondingly receives the power saving signal and switches how it monitors the downlink accordingly.
SYSTEM AND METHOD FOR SELECTING PAGING RESOURCES
A system and method for wireless communication are disclosed herein. One embodiment includes a wireless communication node configuring a plurality of carriers and selecting one of the plurality of carriers for sending a paging message to a wireless communication device based on a Discontinuous Reception (DRX) parameter specific for the wireless communication device. An alternate embodiment includes a wireless communication device selecting one of a plurality of carriers for receiving a paging message to a wireless communication device based on a Discontinuous Reception (DRX) parameter specific for the wireless communication device.
Efficient power utilization for enhanced component carriers
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a narrowband (e.g., a single carrier, anchor carrier, etc.) for a control message that includes a grant for downlink data transmissions. The narrowband containing the control message may be a portion of a system bandwidth. The UE may then monitor a wideband (e.g., all or multiple carriers of the system bandwidth) for data according to the control message. Monitoring the wideband may include additional or alternate circuitry being powered (e.g., receiver circuit switching) to enable reception on an increased range of frequency spectrum. In some examples, a gap or narrowband data transmission may be scheduled between the control message and the grant to allow grant processing and receiver circuitry switching at the UE. In some cases, the control message and data transmission may be received in the same or different transmission time intervals (TTIs).
METHODS AND ARRANGEMENTS TO SUPPORT WAKE-UP RADIO PACKET TRANSMISSION
Logic may define one or more wake-up preambles suitable for high data rates for a wake-up radio (WUR) packet. Logic may define wake-up preamble with different counts of symbols. Logic may generate a wake-up preamble as two microsecond pulses of orthogonal frequency-division multiplexing (OFDM) symbols in a four megahertz (MHz) bandwidth. Logic may generate and receive a high data rate (HDR) WUR preamble or a low data rate (LDR) WUR preamble. The HDR preamble may signal a data rate of 250 kilobits per second and the LDR preamble may signal a data rate of 62.5 kilobits per second. The HDR preamble bit count may be twice a bit count of the LDR preamble. The HDR preamble may be 32 bits. The duration of transmission of the HDR may be 64 microseconds and duration of transmission of the LDR may be 128 microseconds.
