Description

Semi-static scheduling method, base station and user equipment
Technical Field
The embodiment of the invention relates to the field of communication, in particular to a semi-static scheduling method, a base station and user equipment.
Background
Dynamic shared resource scheduling is adopted in LTE/LTE-A. In the uplink transmission process, a User Equipment (UE) needs to apply for resources to a base station first to use time-frequency resources to send data, and can send the data after obtaining authorization of the base station.
Dynamic shared resource scheduling, while greatly optimizing the allocation of resources, also introduces control signaling overhead. In order to reduce the control signaling overhead, semi-persistent scheduling (Semi-Persistent Scheduling, SPS) is introduced for traffic in which the size of the data packets is relatively fixed and the time intervals between the data packets also satisfy a certain regularity.
For example, in Uplink (UL) SPS, the base station transmits an SPS configuration message including an SPS cellular radio network temporary identity (Cell Radio Network Temporary Identity, C-RNTI) and an SPS period to the UE, and then transmits an SPS activation message including SPS resource allocation information (resource allocation). After activation, the UE transmits uplink data using the allocated resources according to the SPS period without scheduling.
However, in some systems that need to transmit various data at fixed time, such as the internet of vehicles (V2X), the control signaling overhead caused by scheduling is large, and may even cause limitation of system capacity. While multiple SPS are an effective way to reduce control signaling overhead, in the prior art, only one SPS is supported at a time, failing to meet the multiple SPS requirements.

Detailed Description
In the following description, for purposes of explanation and not limitation, numerous specific details are set forth, such as particular system architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced in other embodiments, which depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
Referring to fig. 1, a flowchart of a first embodiment of the semi-static scheduling method of the present invention is described. In this embodiment, the execution body is a base station, and the SPS in question is an uplink SPS. The base station may be coupled to a core network and may be in wireless communication with a plurality of user devices to provide communication coverage for an associated sixth zone. The base station may include, but is not limited to, a macro base station, a micro base station, or a pico base station. In various embodiments, a base station may also be interchangeably referred to as a radio base station, access point, node B, evolved node B (eNodeB or eNB), and the like. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may comprise the steps of:
S11: an SPS configuration message is sent to the UE, wherein the SPS configuration message includes at least two SPS information.
The base station may send an SPS configuration message to the UE after or during initial access when the UE enters its coverage to complete the initial access. The SPS configuration message includes information of at least two SPS. In general, each SPS corresponds to a service. Each SPS message at least comprises SPS C-RNTI of SPS, wherein the SPS C-RNTI of different SPS is different.
Each SPS information may further include a period and a resource allocation for the SPS. The resource allocation may include a frequency domain allocation and/or a time domain allocation. The frequency domain allocation specifies which subcarriers the UE should use to upload data. The time domain allocation specifies which TTI (Transmission Time Interval ) within the period the UE should upload data. The periodicity of different SPS may be the same or different, but the resource allocation is different. In addition, in case of supporting transmission of release signaling using RRC message, a release command of the SPS may be included in each SPS information. Release commands for different SPS are different.
S12: and sending control signaling scrambled by the SPS C-RNTI and a target index to the UE.
The control signaling and the target index may be separate or integrated. For example, the target index may be included in the control signaling. The transmission of the control signaling and the target index may be initiated by the UE, i.e. the base station transmits in response to the UE's request; or may be base station initiated, i.e., self-transmitted by the base station.
The target index comprises at least one UE mark, the mark corresponds to the UE in the coverage range one by one, and the marks of different UEs are different. The flag may be an identification code of the UE itself or may be allocated by the base station to the UE. Since control signaling transmitted by a base station may be received by other UEs, a target index needs to be used to indicate a transmission target of the control signaling. By adjusting the number of UE flags in the target index, the number of UEs performing SPS operations may be changed such that a single or multiple UEs respond to a single transmitted control signaling.
SPS C-RNTI scrambling is used to indicate for which SPS the control signaling is. The UE corresponding to the flag included in the target index needs to use a plurality of SPS C-RNTIs in the stored SPS information to attempt to decode the received control signaling, after the decoding is successful, it may be determined that the SPS targeted by the control signaling is the SPS corresponding to the SPS C-RNTIs used for successful decoding, and then corresponding operations are performed on the SPS according to the control signaling.
In general, the control signaling includes activation signaling and/or release signaling, and the operations performed by the corresponding UE include activation and/or release. After activation, the UE will start transmitting uplink data using the SPS resources allocated in the SPS period, and after release, the UE will stop transmitting uplink data using the SPS resources allocated in the SPS period.
In one embodiment of the invention, the base station may send activation signaling and/or release signaling scrambled by SPS C-RNTI to the UE on a physical downlink control channel (Physical Downlink Control Channel, PDCCH) and may also send release signaling scrambled by SPS C-RNTI to the UE using a radio resource control (Radio Resource Control, RRC) message. The base station may also send the release command directly to the UE using an RRC message, where the SPS information should include the release command of the SPS, and the release commands of different SPS are different. The control signaling sent on the PDCCH may use a cyclic redundancy check (Cyclic Redundancy Check, CRC).
The unscrambled activation signaling transmitted using the PDCCH includes fields as shown in table 1 and the release signaling includes fields as shown in table 2. If the target index is included in the activation signaling, a new field for representing the target index needs to be added to the activation signaling.
Table 1:
table 2:
in the prior art, only a single SPS is supported, so that a base station only needs to configure one SPS C-RNTI for each UE. After receiving the SPS control signaling, the UE only needs to use the SPS C-RNTI of the UE to attempt decoding, and if the decoding is successful, the corresponding SPS operation is executed. If the existing SPS technology is simply expanded, different SPS C-RNTIs are respectively allocated to each SPS of each UE, the number of the needed SPS C-RNTIs is the total number of the UEs multiplied by the SPS type, the number is too large, and the practicability is low.
In this embodiment, the SPS configuration message includes at least two SPS information, and different SPS are distinguished by SPS C-RNTI, so as to support multiple SPS. In addition to the control signaling scrambled by the SPS C-RNTI, the base station also transmits a target index to the UE, so that the UE can determine whether to execute the control instruction according to the target index, and determine which SPS should be operated for according to the SPS C-RNTI, thereby reducing signaling overhead while supporting multiple SPS.
Referring to fig. 2, a flow chart of a second embodiment of the semi-static scheduling method of the present invention is described. The present embodiment is based on the first embodiment of the semi-static scheduling method shown in fig. 1, where the UE initiates transmission of the control signaling and the target index. This embodiment is a further extension of the first embodiment of the semi-persistent scheduling method of the present invention, and therefore the same contents as those of the first embodiment of the semi-persistent scheduling method of the present invention will not be repeated here. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may comprise the steps of:
s111: an SPS configuration message is sent to the UE, wherein the SPS configuration message includes at least two SPS information.
S112: an operation request for a corresponding SPS is received from a UE.
The operation request includes an activation request and/or a release request. The operation request should indicate which SPS(s) is targeted in addition to the operation type (activation/release). The UE may send an operation request to the base station according to its own state.
For example, in the internet of vehicles (V2X), the UE may choose whether to enable a certain service (e.g., speed monitoring) based on its own status. If the service is enabled, an activation request is sent to activate the corresponding SPS, starting to periodically upload the status data (real-time speed) of the service. When the UE itself changes state (e.g., parks), it may choose to deactivate the service, send a release request to the base station to release the corresponding SPS, and stop uploading state data.
It should be noted that the transmission of the release request may include both explicit and implicit types. The explicit type refers to the UE directly transmitting a release instruction to the base station, and the implicit type refers to the UE making a release request in such a way that the UE stops transmitting data to the base station using SPS resources. SPS resources indicate which SPS is to be released. For implicit release requests, the base station needs to compare the continuous times of not receiving the data sent by the UE using the corresponding SPS resource with the size of the preset threshold. And when the continuous times are larger than the preset threshold, judging that the implicit type release request is received.
S113: and responding to the operation request, and sending a corresponding control signaling and a target index to the UE.
Wherein, the control signaling should be consistent with the operation type corresponding to the operation request, and the target index should include a flag of the UE transmitting the operation request.
In other embodiments, the base station may also directly send the control signaling and the directory index to the UE to control the UE to perform SPS operations without receiving the operation request, for example, to control the UE to release SPS if the channel quality is poor.
As shown in fig. 3, a flowchart of a third embodiment of the semi-static scheduling method of the present invention is described. The present embodiment is based on the first embodiment of the semi-static scheduling method shown in fig. 1, and the control signaling is sent in a multicast or broadcast manner. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may comprise the steps of:
s121: and sending control signaling and target index to a plurality of UE in a multicast or broadcast mode.
Since the SPS C-RNTI used for scrambling is used to indicate different SPS rather than different UEs, the same control signaling may be sent to multiple UEs at the same time to further reduce signaling overhead. The number of UEs receiving the control signaling and the target index may be greater than the number of target UEs (UEs that need to perform SPS operations according to the control signaling). For example, if three UEs in a group of 4 UEs are target UEs, the base station may choose to send to the 4 UEs simultaneously in a multicast manner and indicate the target UEs in the target index, instead of sending to three UEs respectively.
If the control signaling includes the target index, the base station may select to transmit multiple times in case of a large number of UEs to be transmitted. Preferably, the number of transmissions and the maximum number of flags included in the target index for each transmission may be adjusted to minimize the sum of the two.
The present embodiment may be combined with the second embodiment of the semi-static scheduling method shown in fig. 2, and after that, if the number of operation requests received by the base station in the specified duration T is greater than the specified threshold (0 or a positive integer), the base station sends the control signaling and the target index in a multicast or broadcast manner. At this time, the target index should at least include the mark of the UE sending the operation request; and if the number of the acquired operation requests is less than or equal to a specified threshold, transmitting the control signaling and the target index in a unicast mode. For example, in the internet of vehicles (V2X), when a congestion occurs, there may be a plurality of UEs (vehicles) transmitting release requests, and the base station may notify the plurality of UEs to release SPS in a multicast or broadcast manner.
As shown in fig. 4, a flowchart of a fourth embodiment of the semi-static scheduling method of the present invention is described. The present embodiment is based on a first embodiment of the semi-static scheduling method as shown in fig. 1. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may comprise the steps of:
S13: a flag is assigned to the UE.
The execution of this step should be performed before step S12, before, after or simultaneously with step S11, and of course, the allocated flag may also be included in the SPS configuration message sent in step S11.
The base station may allocate a flag to the UE according to a preset policy, for example, a sequence of entering the coverage area, a position where the base station enters the coverage area, a movement direction, and so on.
In the case of a large number of UEs, the UEs may be grouped for ease of management. The flags allocated to the UE at this time include a group flag and a UE flag, where the UE flag refers to the number of the UE within the group.
This embodiment can be combined with any of the above embodiments. It should be noted that if the flags allocated to the UEs include a group flag and a UE flag, and the base station transmits the control signaling and the target index in a multicast manner, and the group flags of the UEs in one multicast group are the same and all are target UEs (e.g., all transmit the same operation request), the target index may include only the group flag and omit the UE flag, so as to further reduce signaling overhead.
As shown in fig. 5, a flowchart of a fifth embodiment of the semi-static scheduling method of the present invention is described. The method is implemented by UE. The UE may be stationary or mobile, including but not limited to a cell phone, personal Digital Assistant (PDA), wireless modem, tablet, notebook, cordless phone, etc. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may further comprise the steps of:
S21: and receiving an SPS configuration message sent by the base station, wherein the SPS configuration message comprises at least two SPS information.
In general, the UE receives an SPS configuration message after entering the coverage of the base station. The UE may save the SPS information for subsequent SPS operations and data transmission.
S22: and receiving a control signaling and a target index which are sent by the base station and scrambled by the SPS C-RNTI.
S23: and if the target index comprises a self mark, executing corresponding operation on the SPS corresponding to the SPS C-RNTI according to the control signaling.
The flag may be an identification code of the UE itself or may be allocated by the base station to the UE. The target index includes a flag of the UE itself to indicate that the UE is a transmission target of the control signaling, that is, the target UE should perform a corresponding operation.
SPS C-RNTI scrambling is used to indicate for which SPS the control signaling is. The UE may sequentially use the SPS C-RNTI in the stored SPS information to attempt to decode the received control signaling, and after the decoding is successful, may determine that the SPS targeted by the control signaling is the SPS corresponding to the SPS C-RNTI used for successful decoding.
In general, control signaling is classified into two types, activation signaling and release signaling. The UE may confirm whether the control signaling is an activation signaling or a release signaling in case that both conditions including a flag of itself and a successful decoding control signaling are satisfied in the target index. For example, for control signaling transmitted using PDCCH, the UE checks the successfully decoded control signaling with tables 1 and 2 to confirm the type of control signaling, and then performs corresponding operations for the corresponding SPS, including activation and/or release. After activation, the UE will start transmitting uplink data using the SPS resources allocated in the SPS period, and after release, the UE will stop transmitting uplink data using the SPS resources allocated in the SPS period.
Through implementation of the above embodiment, the SPS configuration message includes at least two SPS information, and different SPS are distinguished by SPS C-RNTI, so as to support multiple SPS. In addition to receiving control signaling scrambled by the SPS C-RNTI, the UE also receives the target index, so that the UE can determine whether or not to execute the control instruction according to the target index, and determine which SPS should be operated for according to the SPS C-RNTI, thereby reducing signaling overhead while supporting multiple SPS.
As shown in fig. 6, a flowchart of a sixth embodiment of the semi-static scheduling method of the present invention is described. This embodiment is based on a fifth embodiment of the semi-static scheduling method as shown in fig. 5. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may further comprise the following steps before step S22:
s24: an operation request for a corresponding SPS is sent to a base station.
The UE may send an operation request to the base station according to its own state. The operation request includes an activation request and/or a release request. The operation request should indicate which SPS(s) is targeted in addition to the operation type (activation/release). Generally, the UE transmits a release request to the base station after the end of the current SPS upload data and before the end of the next SPS upload data.
It should be noted that the transmitted release request may include an explicit type and an implicit type, where the explicit type refers to that the UE directly transmits the release instruction to the base station, and the implicit type refers to that the UE makes the release request in a manner of stopping using SPS resources to transmit data to the base station, i.e. stopping using corresponding SPS resources to transmit data to the base station N times in succession, where N is greater than a preset threshold, and the SPS resources indicate which SPS is to be released.
Of course, in other embodiments, the UE may directly receive the control signaling and the target index sent by the base station without sending the operation request.
As shown in fig. 7, a flowchart of a seventh embodiment of the semi-static scheduling method of the present invention is described. The present embodiment is based on the fifth embodiment of the semi-persistent scheduling method shown in fig. 5, and determines whether to execute the SPS operation if the target index is included in the control signaling, where the same parts as those of the fifth embodiment of the semi-persistent scheduling method of the present invention are not described herein. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may further comprise the steps of:
S211: and receiving an SPS configuration message sent by the base station, wherein the SPS configuration message comprises at least two SPS information.
S212: and receiving control signaling scrambled by the SPS C-RNTI sent by the base station, wherein the control signaling comprises a target index.
S213: an attempt is made to decode the control signaling using the SPS C-RNTI in the SPS configuration message.
If the decoding is successful, the process goes to step S214: if the decoding fails, the process is ended.
S214: and judging whether the target index comprises a self mark or not.
If so, go to step S215: if not, ending the flow.
S215: confirm the control signaling type and perform the corresponding SPS operations.
In this embodiment, decoding is first attempted to determine the corresponding SPS, after decoding is successful, the target index in the control signaling is read and whether the target index includes the own flag is determined, and if the target index does not include the own flag, the control signaling type does not need to be confirmed, so that the operations required by the UE are reduced. Of course, in other embodiments, the UE may first confirm the control signaling type and then determine whether the target index includes its own flag.
As shown in fig. 8, a flowchart of an eighth embodiment of the semi-persistent scheduling method of the present invention is described. The present embodiment is based on the fifth embodiment of the semi-persistent scheduling method shown in fig. 5, and determines whether to execute the SPS operation if the target index is not included in the control signaling, where the same parts as those of the fifth embodiment of the semi-persistent scheduling method of the present invention are not described herein. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may comprise the steps of:
S221: and receiving an SPS configuration message sent by the base station, wherein the SPS configuration message comprises at least two SPS information.
S222: and receiving control signaling and a target index which are sent by the base station and scrambled by the SPS C-RNTI, wherein the control signaling does not comprise the target index.
S223: and judging whether the target index comprises a self mark or not.
If so, go to step S224: if not, ending the flow.
S224: the control signaling is decoded using the SPS C-RNTI in the SPS configuration message.
If the decoding is successful, the process goes to step S225: if the decoding fails, the process is ended.
S225: confirm the control signaling type and perform the corresponding SPS operations.
In this embodiment, the target index in the control signaling is read first and whether the target index includes the own flag is judged, and if the target index does not include the own flag, decoding is not required to be attempted, so that operations required by the UE are reduced, and power consumption is reduced. Of course, in other embodiments, the UE may attempt to decode and then determine whether the target index includes its own flag.
As shown in fig. 9, a flowchart of a ninth embodiment of the semi-persistent scheduling method of the present invention is described. This embodiment is based on a fifth embodiment of the semi-static scheduling method as shown in fig. 5. For ease of illustration, the method is described in order. However, portions of the method may be performed in other sequences or in parallel (e.g., concurrently). The method may further comprise the following steps prior to step S22:
S25: and receiving the mark allocated by the base station.
The execution of this step should be performed before step S22, or may be performed before, after or simultaneously with step S21, and the flag may also be included in the SPS configuration message sent in step S21.
The activation/release of SPS may be divided into single activation/release and group activation/release according to the number of UEs in the target index, where the group activation/release requires the base station to send the control signaling and the target index in a multicast or broadcast manner, but the base station does not necessarily need to send the control signaling and the target index in a multicast or broadcast manner, but may be single activation/release. The following are each illustrated in the accompanying drawings.
