The method (100) includes: determining (110) whether each of a plurality of Logical Channels, LCHs, to be transmitted over a sidelink is in a starved state; and selecting (120) at least one of destinations associated with the plurality of LCHs based on whether at least one of the plurality of LCHs is determined to be in the starved state.
Embodiments of the present disclosure provide method and apparatus for session management. A method at a control plane function comprises generating an information element to indicate a number of reports that the user plane function can send a usage report to the control plane function. The method further comprises sending the information element to the user plane function.
Various embodiments of the present disclosure provide a method for random access. The method which may be performed by a terminal device comprises performing a first transmission of a message from the terminal device to a network node in a random access procedure, according to first configuration information. The first transmission of the message comprises a transmission of a first preamble and a transmission of a payload on a shared channel. The method further comprises performing a second transmission of the message from the terminal device to the network node in the random access procedure, according to second configuration information. The second transmission of the message comprises at least one of: a transmission of a second preamble and a retransmission of the payload on the shared channel.
Embodiments of a method in a base station configured to transmit and receive wireless signals to and from a user equipment, UE. A downlink channel response of a first UE antenna is determined, based on uplink signals received from the UE. First preceding weights are calculated based on the determined channel response of the first UE antenna. Orthogonal or quasi-orthogonal preceding weights are determined based on the first preceding weights. First and second downlink signal layers are transmitted using the first preceding weights and the orthogonal or quasi- orthogonal preceding weights.

SIGNALING PARAMETER VALUE INFORMATION IN A PARAMETER SET TO REDUCE THE AMOUNT OF DATA CONTAINED IN AN ENCODED VIDEO BITSTREAM
A method (400) performed by a decoder (260, 600, 701) for decoding a bitstream comprising a picture parameter set, PPS, and a first set of slices. The method includes obtaining (s402) the picture parameter set. The method also includes decoding (s404) a syntax element included in the picture parameter set to obtain an indicator value. The decoder is configured such that if the indicator value is set to a first value then the decoder determines that a picture header included in the bitstream comprises a parameter value corresponding to a particular parameter, otherwise the decoder determines that each slice included in the first set of slices comprises a parameter value corresponding to the particular parameter. If the picture header comprises the parameter value corresponding to the particular parameter, then this parameter value is used to decode slice data of each slice included in the first set of slices.

PRECONFIGURED UPLINK RESOURCES - CONFIGURATION FOR TA VALIDITY IN ENTIRE CELL
Systems and methods for determining timing advance (TA) validity are disclosed. In some embodiments, systems and methods are disclosed herein in which a wireless device implicitly considers a TA to be valid in a full cell when no TA validation mechanisms are explicitly configured. In other embodiments, systems and methods are disclosed herein in which a timer serves a dual purpose. If the timer is set to infinity, a wireless device will always consider a TA to be valid within a given cell, and at the same time will disable other TA validation mechanisms. Otherwise, the wireless device will interpret the timer as indicating for how long the TA value that the wireless device possesses is considered to be valid. Benefits of the solutions described herein include reducing signaling bits in the configuration and avoiding the possibility of conflicting configurations.
