Detailed Description
As background art shows, an existing terminal device (also called a User Equipment, UE for short) must initiate a random access procedure to switch to an RRC connected state before receiving downlink data, which causes a large RRC signaling overhead and a large energy consumption of the terminal device, and also causes unnecessary downlink data transmission delay.
To solve the foregoing technical problem, an embodiment of the present invention provides a data transmission method, including: acquiring configuration information of a preconfigured downlink resource to determine a resource position of the preconfigured downlink resource; during the idle state or the inactive state, directly receiving downlink data in the pre-configured downlink resource; the direct reception refers to data reception without switching to the RRC connected state.
The embodiment ensures that the UE can receive the data without initiating the random access to enter the connection state, is beneficial to reducing signaling overhead, saving resources and reducing equipment energy consumption, and can reduce unnecessary downlink data transmission delay. Specifically, a periodic preconfigured downlink resource is introduced in an idle state or an inactive state, and the UE can directly receive downlink data on the preconfigured downlink resource, thereby preventing the UE from initiating a random access process to enter an RRC connected state. The downlink data is directly received in the preconfigured downlink resource, so that the transmission delay of the downlink data is effectively reduced, and the UE does not need to perform signaling interaction with a network to switch states and request scheduling resources, so that the reduction of signaling overhead, resource saving, equipment energy consumption reduction and downlink data transmission delay are possible.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a data transmission method according to a first embodiment of the present invention.
This embodiment may be performed by the user equipment side, such as by the UE.
The embodiment can be applied to application scenes of 2G, 3G, 5G or future communication systems.
Specifically, referring to fig. 1, the data transmission method according to this embodiment may include the following steps:
step S101, obtaining configuration information of a pre-configured downlink resource to determine a resource position of the pre-configured downlink resource;
step S102, during idle state or inactive state, directly receiving downlink data in the pre-configured downlink resource;
the direct reception refers to data reception without switching to the RRC connected state.
In one implementation, the step S101 may be performed when the UE is in an RRC connected state, and the step S102 is performed when the UE switches from the RRC connected state to an idle state or an inactive state.
Specifically, the configuration information of the preconfigured downlink resource may be carried through RRC signaling.
For example, the step S101 may include the steps of: receiving RRC signaling during an RRC connected state; and acquiring the configuration information of the preconfigured downlink resource from the RRC signaling.
In one implementation, the preconfigured downlink resource may be periodically repeated, as shown in fig. 2.
Specifically, the configuration information of the preconfigured downlink resource may include: and the period and the initial position of the pre-configured downlink resource. Wherein the starting position is a time-frequency position of a first preconfigured downlink resource in periodically repeated preconfigured downlink resources configured for the UE; the period refers to a time interval between two adjacent pre-configured downlink resources.
Further, according to the configuration information of the preconfigured downlink resources, the time-frequency position of each preconfigured downlink resource which is periodically repeated can be determined.
In a specific implementation, different UEs may configure different preconfigured downlink resources, where the different preconfigured downlink resources may be distinguished in a time-frequency domain, or may correspond to the same resource in a time domain, but are distinguished by a space division format, a code division format, and the like.
For example, the network may configure different preconfigured downlink resources for each UE that establishes RRC connection with the network, and send configuration information of the preconfigured downlink resources of each UE to each UE through each RRC signaling.
In a specific implementation, in response to receiving the configuration information of the preconfigured downlink resource, the UE may determine a resource location of the preconfigured downlink resource configured to the UE, and receive downlink data sent to the UE by a network at the resource location of the preconfigured downlink resource after switching to an idle state or an inactive state in the future. During the period of receiving downlink data, the UE does not need to initiate a random access process and switch to an RRC connection state.
In one implementation, the step S102 may include the steps of: receiving indication information, wherein the indication information is used for indicating the activation or deactivation of the subsequent first number of pre-configured downlink resources; and directly receiving the downlink data at the activated subsequent first number of pre-configured downlink resources.
Specifically, the indication Information may be carried by common Downlink Control Information (DCI), dedicated DCI, and/or a paging message.
Further, the indication information may include a plurality of bits, where the plurality of bits correspond to the plurality of UEs one to one, or a part of the plurality of bits correspond to the same UE, and each bit is used to indicate activation or deactivation of a subsequent first number of preconfigured downlink resources configured for the corresponding UE. Taking the indication information carried by the common DCI as an example, since the common DCI may be sent to a plurality of UEs, the indication information carried by the common DCI may indicate whether the subsequent preconfigured downlink resources allocated to the plurality of UEs are available. Therefore, the UE can know whether the UE can receive the downlink data by using the pre-configured downlink resource subsequently or not by only sending one indication message, and the signaling overhead is favorably reduced.
Further, the configuration information of the preconfigured downlink resource may include the first number of candidate value sets, and the first number indicated by the indication information is selected from the candidate value sets. Therefore, the number of the activated or released pre-configured downlink resources can be dynamically adjusted according to the actual situation, so that the resources are better saved.
In one implementation, the UE may determine whether a subsequent first number of preconfigured downlink resources is available by receiving the common dci (common dci) issued by a network (or a control node).
Specifically, the common DCI refers to DCI control information that all UEs in a cell or a group of UEs in a cell can receive. Further, the transmission parameter configuration related to the common DCI is issued to the UE through a broadcast message or an RRC dedicated signaling.
Further, the network may indicate, through the common DCI, whether a UE configured with the preconfigured downlink resources is subsequently available (i.e., activated) for a first number of preconfigured downlink resources.
For example, a dedicated bit field may be added to the common DCI to activate or deactivate a first number of subsequent preconfigured downlink resources of the UE configured with the preconfigured downlink resources.
Further, each terminal device configured with the preconfigured downlink resource corresponds to one bit (bit) in the common DCI. When the network configures the pre-configured downlink resource for the UE, the network indicates the corresponding bit of the UE in the common DCI. Correspondingly, in an idle state or an inactive state, the UE determines whether the subsequent first number of preconfigured downlink resources are available (i.e., activated) according to a value of a bit corresponding to the common DCI.
For example, when the corresponding bit value is 0, the UE determines that the subsequent first number of preconfigured downlink resources is unavailable. For another example, when the corresponding bit value is 1, the UE determines that the subsequent first number of preconfigured downlink resources are available.
Further, the correspondence between the specific value of the corresponding bit in the common DCI and whether the subsequent first number of preconfigured downlink resources are activated may be indicated in advance through RRC signaling.
Further, the corresponding bit of the UE in the common DCI may be calculated and determined based on a formula UE ID mod x, where the UE ID is an identity (identity, abbreviated as ID) of the UE, mod represents a remainder operation, x is a numerical value indicated in advance by a network, and x may be included in configuration information of the preconfigured downlink resource. The above formula can also be written as mod (UE ID, x), where mod () represents the remainder of the parenthesis. Each UE can determine the corresponding bit on the common DCI according to its UE ID and x indicated by the network. The specific value of x indicated by the network to different UEs may be the same or different.
Further, the first number may be included in configuration information of the preconfigured downlink resource and indicated to the UE in advance through RRC signaling.
For example, when the corresponding bit value is 0, the UE determines that the subsequent m preconfigured downlink resources are unavailable. For another example, when the corresponding bit value is 1, the UE determines that the subsequent m preconfigured downlink resources are available. Wherein m is the first number.
Further, the subsequent first number of preconfigured downlink resources may be the first number of preconfigured downlink resources since the common DCI was received. For example, referring to fig. 2, assuming that common DCI is received at time t0 and the first number is 2, two preconfigured downlink resource activations or deactivations located after time t0 are illustrated.
Further, the first number of different UEs configured may be the same or different.
Further, the additional bit field in the common DCI may use reserved bits in the common DCI.
In a variation, the first number may also be dynamically indicated by the common DCI, that is, each UE may be indicated in the common DCI to activate or deactivate the next specific number of preconfigured downlink resources. Thus, the system has more flexibility in the use of resources.
In one implementation, the UE may determine whether a subsequent first number of preconfigured downlink resources is available by receiving dedicated DCI delivered by a network (or a control node).
Specifically, DCI at the UE level (i.e., UE-specific) refers to DCI that can be received only by a specific UE. Further, the transmission parameter configuration related to the dedicated DCI is configured to the UE through RRC dedicated signaling.
Further, the network may indicate, through the dedicated DCI, whether a UE configured with the preconfigured downlink resources is subsequently available (i.e., activated) for a first number of preconfigured downlink resources.
For example, a specific bit may be added to the dedicated DCI to activate or deactivate a first number of subsequent preconfigured downlink resources of the UE configured with the preconfigured downlink resources.
Further, after receiving the DCI, the UE determines whether the subsequent first number of preconfigured downlink resources are available (i.e., activated) according to a value of a corresponding bit in the DCI.
For example, when the corresponding bit value is 0, the UE determines that the subsequent first number of preconfigured downlink resources is unavailable. For another example, when the corresponding bit value is 1, the UE determines that the subsequent first number of preconfigured downlink resources are available.
Further, the network may configure a plurality of values as the candidate values of the first number to the UE when configuring the preconfigured downlink resource to the UE. Further, the network may indicate in the dedicated DCI from which one of the plurality of candidate values the first number of pre-configured downlink resources that this time indicates activation or deactivation is taken.
For example, assuming that there are 2 bits in the dedicated DCI for pre-configuring activation and deactivation of the downlink resource, the first number of candidate value sets for the network configuration is {2,4,6 }. When the value of the corresponding bit is 00, the UE determines that the subsequent 2 preconfigured downlink resources are unavailable; when the value of the corresponding bit is 01, the UE determines that the subsequent 2 preconfigured downlink resources are available; when the value of the corresponding bit is 10, the UE determines that the subsequent 4 preconfigured downlink resources are available; and when the value of the corresponding bit is 11, the UE determines that the subsequent 6 pre-configured downlink resources are available.
Further, the correspondence between the specific value of the corresponding bit in the DCI and the first number and whether the first number of preconfigured downlink resources is activated may be indicated in advance through RRC signaling.
Further, the first number of sets of candidate values with which different UEs are configured may be the same, partially the same, or completely different.
Further, the additional bits in the special DCI may use reserved bits in the special DCI.
When the configuration information of the preconfigured downlink resource includes the first number of candidate value sets, each UE may correspond to a bit block in the dedicated DCI carrying the indication information, where the bit block includes multiple bits.
In this embodiment, the preconfigured downlink resource activation means that the preconfigured downlink resource is available, that is, the network activates to send downlink data in the preconfigured downlink resource, and the UE may also activate to receive the downlink data in the preconfigured downlink resource.
Correspondingly, the deactivation of the preconfigured downlink resource means that the preconfigured downlink resource is unavailable, that is, the network does not activate and send downlink data in the preconfigured downlink resource, and the UE also suspends activating and receiving the downlink data in the preconfigured downlink resource.
Further, when the preconfigured downlink resource is deactivated, the preconfigured downlink resource may be released by the network and allocated to other UEs or used for other purposes.
In one implementation, the UE may determine whether a subsequent first number of pre-configured downlink resources are available by receiving a paging message sent by the network.
Specifically, the role of the paging message may include: (1) sending a call request to the UE in the RRC connection state; (2) informing the UE in an RRC idle state, an RRC inactive state and an RRC connected state that system information changes; (3) the Earthquake and Tsunami notification is used for instructing the UE to start receiving an Earthquake and Tsunami Warning System (ETWS for short) primary (primary) notification and/or an ETWS secondary (secondary) notification, and instructing the UE to start receiving a Commercial Mobile Warning System (CMAS for short) notification. If UE is paged, system information is updated or earthquake and tsunami occur, the base station firstly sends a wake-up signal, and after the UE detects the wake-up signal, the UE monitors a Physical Downlink Control signal (PDCCH) of paging to receive paging information; otherwise, the UE will always stay in the sleep state to achieve the purpose of power saving. In a New Radio (NR) system, a UE may use Discontinuous Reception (DRX) in an RRC idle state and an RRC inactive state in order to reduce power consumption. The UE may periodically (for example, the period may be a DRX period) monitor a Paging Occasion (PO).
Further, a dedicated field may be set in the paging message for indicating whether a UE subsequently has a first number of pre-configured downlink resources available. Accordingly, the UE may determine whether a subsequent first number of pre-configured downlink resources are available (i.e., activated) by receiving a paging message in an idle state or an inactive state.
Further, the first number may be indicated to the UE by configuration information of the preconfigured downlink resource.
Further, the configuration information of the preconfigured downlink resource may include the candidate value set of the first number, and the UE determines the specific value of the first number according to the specific value of the corresponding bit in the paging message, and whether the preconfigured downlink resource of the first number is activated.
In one implementation, the step S102 may include the steps of: if the downlink data is correctly received and ACK is fed back in the preconfigured downlink resource, starting a timer; and determining the preconfigured downlink resources before the timer is overtime as a deactivation state.
Specifically, the correct reception means that the downlink data is successfully received and decoded.
Further, after receiving the downlink data, the UE may send a Hybrid Automatic Repeat reQuest (HARQ) ACKnowledgement or negative ACKnowledgement (ACK/NACK) message to the network. Wherein, the ACK indicates that the UE correctly receives the downlink data, and the NACK indicates that the UE fails to correctly receive the downlink data.
Further, the specific value of the timer may be indicated to the UE in advance through configuration information of the preconfigured downlink resource.
Further, the time granularity of the timer may be selected from: millisecond, subframe, frame, time slot and period of pre-configuring downlink resource.
In this embodiment, the UE in the idle state or the inactive state may receive downlink data from the first preconfigured downlink resource in each preconfigured downlink resource configured by the network. And when the downlink data is correctly received and ACK is fed back in a certain preconfigured downlink resource, the UE starts the timer. Further, the preconfigured downlink resources that are located after the preconfigured downlink resources that correctly receive the downlink data are not available until the timer expires.
In a specific implementation, after the step S102, the data transmission method according to this embodiment may further include the steps of: and sending receiving feedback information pointing to the downlink data in a preconfigured uplink feedback resource.
Specifically, the network may configure a preconfigured downlink resource for the UE through RRC signaling and also configure a corresponding preconfigured uplink feedback resource for the UE.
In one implementation, the preconfigured uplink feedback resources may correspond to preconfigured downlink resources one to one. That is, each preconfigured downlink resource is associated with a preconfigured uplink feedback resource, as shown in fig. 3.
Further, there may be a fixed time interval (offset, which may also be referred to as an offset) between the preconfigured downlink resource and the associated preconfigured uplink feedback resource, and a specific value of the time interval may be configured by RRC signaling. That is, the configuration information of the preconfigured downlink resource may include: a time interval of a preconfigured uplink feedback resource associated with said preconfigured downlink resource relative to said preconfigured downlink resource.
Further, the UE may determine the preconfigured uplink feedback resource corresponding to each preconfigured downlink resource according to the resource location of the preconfigured downlink resource and the time interval.
Further, after receiving downlink data in a certain preconfigured downlink resource, the UE may send, in a preconfigured uplink feedback resource associated with the preconfigured downlink resource, reception feedback information pointing to the downlink data. Wherein the reception feedback information is used to indicate whether the downlink data is successfully received, that is, the reception feedback information is ACK or NACK.
For example, referring to fig. 3, assuming that the UE receives downlink data at the preconfigured downlink resource at time t1 and the decoding is successful, the ACK may be sent to the network at the preconfigured uplink feedback resource at time t2 associated with the preconfigured downlink resource at time t 1.
In a variation, the time interval between different preconfigured downlink resources and their associated preconfigured uplink feedback resources may be the same or different.
In one implementation, the preconfigured uplink feedback resource may be associated with a plurality of preconfigured downlink resources. That is, the network may configure one preconfigured uplink feedback resource associated with every N preconfigured downlink resources. N is an integer of 2 or more.
Correspondingly, the ACK or NACK feedback corresponding to the downlink data on each N preconfigured downlink resources is sent to the network through the same preconfigured uplink feedback resource. Wherein, the parameter N can be configured by RRC signaling.
Further, there may be a fixed time interval (offset) between the nth preconfigured downlink resource and the preconfigured uplink feedback resource in every N preconfigured downlink resources, and a specific value of the time interval may be configured by RRC signaling.
Further, the UE may determine the preconfigured uplink feedback resource corresponding to each N preconfigured downlink resources according to the resource location of the nth preconfigured downlink resource and the time interval.
Further, after receiving downlink data in a certain preconfigured downlink resource, the UE may send, in a preconfigured uplink feedback resource associated with the preconfigured downlink resource, reception feedback information pointing to the downlink data. Wherein the reception feedback information is used to indicate whether the downlink data is successfully received, that is, the reception feedback information is ACK or NACK.
For example, referring to fig. 4, assume that the network configures N + N 'total preconfigured downlink resources to the UE, where each N preconfigured downlink resources are associated with one preconfigured uplink feedback resource in the front, and each N' preconfigured downlink resources are associated with one preconfigured uplink feedback resource in the back. When the UE receives downlink data at time t3 and time t4, ACK or NACK may be sent by the preconfigured uplink feedback resources associated with the preconfigured downlink resources at the two times (the same resource in the example shown in fig. 4, that is, the preconfigured uplink feedback resource at time t 5) according to the receiving condition.
In a variation, the time intervals between the N different preconfigured downlink resources and the associated preconfigured uplink feedback resources may be the same or different.
In a variation, specific values of the preconfigured downlink resources associated with different preconfigured uplink feedback resources may be the same or different.
In one implementation, the configuration information of the preconfigured downlink resource may include: and the period and the initial position of the uplink feedback resource are preconfigured.
That is, similar to the preconfigured downlink resource, the preconfigured uplink feedback resource is also periodically repeated. Correspondingly, the network configures the periodically repeated preconfigured downlink resources through the dedicated RRC signaling, and also configures the periodically repeated preconfigured uplink feedback resources.
Further, the granularity of the period for pre-configuring the uplink feedback resource may be selected from: and pre-configuring the period, subframe, millisecond, frame and time slot of the downlink resource. That is, the period of the preconfigured uplink feedback resources may be equal to the period of the preset number of preconfigured downlink resources. Alternatively, the granularity of the period of the preconfigured uplink feedback resource may be a preset number of subframes, milliseconds, frames, or time slots.
Further, after the step S102, the data transmission method according to this embodiment may further include the steps of: determining a preconfigured uplink feedback resource closest to the preconfigured downlink resource receiving the downlink data; and sending receiving feedback information pointing to the downlink data in the determined preconfigured uplink feedback resources.
Specifically, the preconfigured downlink resources in each preconfigured uplink feedback resource period are associated with the uplink feedback resources in the current period. That is, the UE sends and receives feedback information on the last preconfigured uplink feedback resource after receiving the downlink data.
Further, the UE may determine the uplink feedback resource associated with each preconfigured downlink resource according to the periodic preconfigured downlink resource and the periodic preconfigured uplink feedback resource.
Referring to fig. 5, according to the period 1 and the starting position of the preconfigured downlink resource and the period 2 and the starting position of the preconfigured uplink feedback resource, the resource positions of each of the preconfigured downlink resource and the preconfigured uplink feedback resource may be determined. Further, it may be determined that preconfigured downlink resource 51 and preconfigured downlink resource 52 in fig. 5 are associated with preconfigured uplink feedback resource 53, and preconfigured downlink resource 54 and preconfigured downlink resource 55 are associated with preconfigured uplink feedback resource 56.
Therefore, by adopting the embodiment, the UE can receive the data without initiating the random access to enter the connection state, thereby being beneficial to reducing signaling overhead, saving resources, reducing equipment energy consumption and reducing unnecessary downlink data transmission delay. Specifically, a periodic preconfigured downlink resource is introduced in an idle state or an inactive state, and the UE can directly receive downlink data on the preconfigured downlink resource, thereby preventing the UE from initiating a random access process to enter an RRC connected state. The downlink data is directly received in the preconfigured downlink resource, so that the transmission delay of the downlink data is effectively reduced, and the UE does not need to perform signaling interaction with a network to switch states and request scheduling resources, so that the reduction of signaling overhead, resource saving, equipment energy consumption reduction and downlink data transmission delay are possible.
