The present application relates to methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to digital wireless communication, and more specifically, to techniques related to maintaining a PDCCH blind decoding budget in the case that a cell can be scheduled by another cell and by itself. In one exemplary aspect, a method for wireless communication is disclosed. The method includes receiving, by a terminal on a scheduling cell, control information for a first cell according to a rule that an amount of blind decoding resources for the first cell does not exceed a budget, wherein the first cell is scheduled by the scheduling cell and the first cell is also scheduled by itself.

This application provides a communication method, a terminal device, and a network device, so that blind detection can be performed in different scheduling periods based on a maximum number of blind detection in a preset time period, thereby helping to reduce energy consumption that is caused to a terminal device by blind detection, and reduce blind detection complexity. The method includes: determining, by a terminal device, a maximum number of blind detection in a first time unit, where the first time unit is one or more symbols; and performing, by the terminal device, physical downlink control channel blind detection in the i.sup.th blind detection occasion, where the first time unit includes N blind detection occasions, and a number of physical downlink control channel blind detection performed by the terminal device in the N blind detection occasions is less than or equal to the maximum number of blind detection, where i and N are positive integers, i≤N and N≥2.

A method includes determining a delivery performance of a data flow being transmitted from a first network equipment to a second network equipment over a network; determining whether the network is congested based on the determined delivery performance of the data flow being transmitted to the second network equipment; and pacing delivery of the data flow to the second network equipment by reducing a rate at which the data flow is delivered to the second network equipment when the network is determined to be congested.

Embodiments of this disclosure improve the reliability of blind decoding when beamforming is used by having a user equipment (UE) receive a single downlink control information (DCI) message with different transmission and/or reception parameters. In some embodiments, a UE receives more than one set of configuration parameters, where any two sets of configuration parameters out of the more than one set of configuration parameters have at least one different parameter. The UE may receive two sets of configuration parameters each having a different transmission modes, but the same search space type. Additional examples are also provided.

A terminal device receives first information from a network device, where the first information indicates transmission direction information and/or service load information. The terminal device receives downlink control information DCI from the network device based on the first information. The network device may configure a DCI transmission mode by using the first information based on a characteristic of a to-be-transmitted service of the terminal device.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that an uplink demodulation reference signal (DMRS) bundling operation associated with a physical channel has started. The UE may change an activity state of a reception operation associated with periodic downlink communications based at least in part on determining that the uplink DMRS bundling operation has started. Numerous other aspects are described.

Methods and apparatuses for enhancing the reliability and performance of the PDCCH in a wireless network. The method performed by a UE comprises: receiving a configuration of search space sets for the PDCCH, each search space set comprises a number of PDCCH candidates made up of a number of resource elements; monitoring for DCIs of a specific format as indicated in the configured PDCCH candidates; wherein a configuration or an indication of an association of the search space sets with a search space set pool is provided to the UE, and at least two PDCCH candidates from the search space sets are associated with the same DCI content, or an association of two or more TCI states with a single CORESET is obtained from the network node; and applying the configuration(s) or indication of the association for receiving one or more PDCCH(s) on the search space sets.

Provided are a method and apparatus for transmitting control information, a method and apparatus for receiving control information, and a communication system. The method includes that: at least one modulation order of a Physical Downlink Control Channel (PDCCH) is determined; and Downlink Control Information (DCI) is modulated using the at least one modulation order.

Methods, systems, and devices for wireless communications provide for transmission of a beam switch command to a user equipment (UE) via control channel signaling. The UE may establish a connection with a base station using a first transmission beam, receive configuration information configuring the UE to select between a first decoding hypothesis corresponding to downlink control information (DCI) including a bit field including a beam switch command and a second decoding hypothesis corresponding to the DCI not including the bit field, receive a downlink control channel transmission via the first transmission beam, decode the downlink control channel transmission in accordance with the configuration information to obtain decoded DCI, and communicate with the base station based at least in part on the decoded DCI.

A base station is disclosed, including an information size adjusting section configured to adjust a size of control information based on a first basic information size of control information mapped on a user equipment (UE) specific search space in a first component carrier. The base station also includes a transmitter configured to transmit the control information mapped on the UE specific search space. A first determination method for determining the first basic information size is different from a second determination method for determining a second basic information size of control information mapped on a common search space in the first component carrier. The first determination method for determining the first basic information size is different from a third determination method for determining a third basic information size of control information mapped on a search space in a second component carrier that is different from the first component carrier.
